FULLY AUTOMATIC FRAMING MACHINE FOR ALUMINUM PROFILE
TECHNICAL FIELD
[0001] The present disclosure relates to the field of aluminum profile
production, and in
particular to a fully automatic framing machine for aluminum profiles.
BACKGROUND
[0002] During production of aluminum profiles, the aluminum profiles are
layered and
separated by parting strips to prevent surface damages and frictions between
upper and lower
layers of aluminum profiles. For ease of use, the parting strips are uniformly
stored in a parting
strip frame. Currently, parting strips are usually manually taken out from the
parting strip frame.
Moreover, the parting strips taken out are placed randomly and cannot meet the
requirements on
automatic production.
[0003] After the parting strips are placed, the parting strips and rows of
aluminum profiles are
lifted and framed manually, which is time-consuming, laborious and cost-
ineffective. Some
aluminum profile production enterprises employ an automatic framing machine to
frame the
aluminum profiles. It mainly includes a longitudinal movement mechanism and a
gripping
mechanism. The gripping mechanism is configured to grip the parting strips of
the aluminum
profiles. The longitudinal movement mechanism is configured to deliver the
aluminum profiles
and the parting strips together to the material frame. Nevertheless, the
parting strips are placed
manually. In order to align the parting strips and the grid mechanism, there
are usually three or
less parting strips. As a result, the aluminum profiles are supported
insufficiently and are easily
damaged in delivery.
SUMMARY

time-consuming and laborious, the present disclosure provides a fully
automatic framing
machine for aluminum profiles. The present disclosure can take out and place

[0018] The present disclosure has the following beneficial effects.
[0019] With the cooperation between the parting strip frame, the parting strip
delivery device
and the aluminum profile framing device, the present disclosure can take out
and place the
parting strips automatically, and deliver and frame the aluminum profiles
automatically, with
stable and reliable operation and no manual intervention.
[0020] The parting strip frame can accommodate more parting strips, because
the parting strips
can be layered and stacked in the frame body, and the parting strips are
arranged closely. The
bottommost parting strips are supported by the bottom support members. The
bottom center of
the frame body is hollow, such that the automatic lift mechanism moves up the
parting strips
from the bottom of the frame body. The end limit members are narrower than the
parting strips.
After the parting strips abut against the end limit members, there is a gap
between the ends of the
parting strips and the frames, and the parting strips can swing horizontally
within certain limits.
As a result, the two ends of the parting strips are not stuck in the frame
body and are smoothly
discharged from the top of the frame body.
[0021] The lift mechanism can lift the parting strips layered and stacked in
the parting strip
frame. Specifically, an uppermost layer of the parting strips enter the
layering mechanism, with
two ends of the parting strips pressed and fixed by the layering mechanism.
Then, the lift
mechanism drives parting strips other than the uppermost layer of the parting
strips to move
down, such that the uppermost layer of the parting strips are separated from
the parting strips
thereunder. The guide rails are stretched out. The guide rails are located
between the uppermost
4

(FS2214P-CA-PCT)
layer of the parting strips and the parting strips thereunder. The layering
mechanism releases the
uppermost layer of the parting strips, such that the uppermost layer of the
parting strips are
carried on the guide rails. At last, the uppermost layer of the parting strips
are pushed forward by
the push assembly along the guide rails. Whenever the push assembly pushes the
uppermost
layer of the parting strips by a distance equivalent to a width of one parting
strip, the endmost
parting strip on the guide rails falls onto a feeding conveyor belt of a
parting strip placement
mechanism, thereby implementing the one-by-one delivery of the parting strips.
With the stable
and reliable operation, and the high storage density of the parting strips,
the present disclosure
can meet the use requirements on the parting strips for a long time after
adding one frame of the
parting strips.
[0022] The parting strip gripping frame is sequentially connected to the
lateral movement
mechanism, the vertical movement mechanism and the longitudinal movement
mechanism to
ensure the stable movement of the parting strip gripping frame. The lateral
movement
mechanism for stretching a lower end of the parting strip gripping frame to a
bottom of each of
the parting strips is in the last among the three movement mechanisms.
Therefore, there are
fewer components that need to move left and right, and the parting strip
gripping frame moves
left and right more accurately and sensitively.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0039] In order to make the objectives, technical solutions and advantages of
the present
disclosure clearer, the present disclosure will be further described in detail
below with reference
to the drawings. It should be noted that the orientational terms illustrated
or to be illustrated in
the specification, such as up, down, left, right, forward, backward, inside
and outside, are only
based on the accompanying drawings of the present disclosure, and do not form
specific limits to
the present disclosure.
[0040] As shown in FIG. 1 to FIG. 3, an embodiment of the present disclosure
provides a fully
automatic framing machine for aluminum profiles, including a parting strip
frame 100, a parting
strip delivery device 101 and an aluminum profile framing device 102. The
parting strip frame
100 includes a frame body 8, end limit members 91 and bottom support members
92. The frame
body 8 is composed of rectangular frames 81. The bottom support members 92 are
provided at a
bottom of the frame body 8 in parallel and configured to support parting
strips 3'. The end limit
members 91 are vertically provided inside the frame body 8. The end limit
members 91 are
narrower than the parting strips 3'.
[0041] The parting strip frame can accommodate more parting strips 3', because
the parting
strips 3' can be layered and stacked in the frame body 8, and the parting
strips 3' are arranged
closely. The bottommost parting strips 3' are supported by the bottom support
members 92. The
bottom center of the frame body 8 is hollow, such that the automatic lift
mechanism lifts the
parting strips 3' from the bottom of the frame body 8. The end limit members
91 are narrower
than the parting strips 3'. After the parting strips 3' abut against the end
limit members 91, there
is a gap between the ends of the parting strips 3' and the frames 81, and the
parting strips 3' can
swing horizontally within certain limits. As a result, the two ends of the
parting strips 3' are not
6
CA 03163642 2022- 7- 4

CA National Phase of PCT/CN2021/111374
(FS2214P-CA-PCT)
stuck in the frame body 8, and the parting strips 3' are smoothly discharged
from the top of the
frame body 8.
[0042] Preferably, referring to FIG. 4, the end limit members 91 are of an
elongated shape and
are arranged in the frame body 8 at a predetermined distance. More preferably,
central positions
of ends of the parting strips 3' directly face the corresponding ones of the
end limit members 91.
With the end limit members 91 directly facing the central positions of the
ends of the parting
strips 3', point contacts are formed between the parting strips 3' and the end
limit members 91
and at the central positions of the ends of the parting strips 3'. Therefore,
the parting strips 3' can
rotate to some extent while limited, ensuring that multiple layers of stacked
parting strips 3'
move up and down smoothly in the frame body 8.
[0043] Preferably, the frame body 8 is provided with baffles 82 at two sides
corresponding to
the ends of the parting strips 3' and hollow portions 83 at the other two
sides. With the baffles 82,
the parting strips 3' cannot be stretched out from an end direction. Through
the hollow portions
83, the use of the parting strips 3' is directly observed by an operator. In
order to better support
the parting strips 3', the bottom support members 92 each are composed of two
rectangular tubes
921 at the bottom of the frame body 8. The rectangular tubes 921 are stretched
out from the
bottoms of the frames 81 to the center of the frame body 8, and support the
two ends of the
parting strips 3'.
[0044] As shown in FIG. 5 to FIG. 7, the parting strip delivery device 101
includes a lift
mechanism 5, a layering mechanism 6 and a conveyance mechanism 7. The lift
mechanism 5 is
provided below the parting strips 3', and configured to lift parting strips
3'. The layering
mechanism 6 is provided above the lift mechanism 5, and includes a clamping
cylinder 61 and
clamping plates 62. The clamping plates 62 are provided on a piston rod of the
clamping cylinder
61. The clamping plates 62 are symmetrically provided at two sides close to
the ends of the
parting strips 3'. The clamping plates 62 can move horizontally under the
driving of the clamping
cylinder 61, thereby fixing or loosening the parting strips 3'. The conveyance
mechanism 7
includes guide rails 71, a guide cylinder 72 and a push assembly 73. The guide
rails 71 are
provided on the guide cylinder 72. The guide rails 71 can be stretched out or
retracted back under
the driving of the guide cylinder 72. The push assembly 73 is configured to
push forward parting
strips 3' on the guide rails 71.
[0045] Referring to FIG. 9, the push assembly 73 includes a push frame 731
arranged above the
guide rails 71. Two ends of the push frame 731 each are provided with a
chainwheel 732. A chain
733 is provided on the chainwheel 732. A push claw 734 is provided on the
chain 733. The
chainwheel 732 is connected to a push motor 103. The lift mechanism 5 includes
a lift plate 51, a
lift leadscrew 52 and a leadscrew drive mechanism 53. The lift plate 51 is
configured to push a
7
CA 03163642 2022- 7- 4
Our Ref: 43970-19
CA National Phase of PCT/CN2021/111374
(FS2214P-CA-PCT)
row of parting strips 3 to move up and down together. The lift leadscrew 52 is
connected to the
lift plate 51, and can move up and down vertically under the driving of the
leadscrew drive
mechanism 53. The leadscrew drive mechanism 53 includes a motor and a nut. The
motor
rotationally drives the nut. The nut is sleeved on the lift leadscrew 52.
[0046] In the embodiment, referring to FIG. 11, the lift mechanism 5 can lift
the parting strips 3'
layered and stacked in the parting strip frame. Specifically, an uppermost
layer of the parting
strips 3' enter the layering mechanism 6, with two ends of the parting strips
3' pressed and fixed
by the layering mechanism 6. Then, the lift mechanism 5 drives parting strips
3b' other than the
uppermost layer of the parting strips 3a' to move down, such that the
uppermost layer of the
parting strips 3a' are separated from the parting strips 3W thereunder. The
guide rails 71 are
stretched out. The guide rails 71 are located between the uppermost layer of
the parting strips 3a'
and the parting strips 3b' thereunder. The layering mechanism 6 releases the
uppermost layer of
the parting strips 3a', such that the uppermost layer of the parting strips
3a' are carried on the
guide rails 71. At last, the uppermost layer of the parting strips 3a' are
pushed forward by the
push assembly 73 along the guide rails 71. Whenever the push assembly 73
pushes the
uppermost layer of the parting strips 3a' by a distance equivalent to a width
of one parting strip
3a', the endmost parting strip on the guide rails 71 falls onto a feeding
conveyor belt 5' of a
parting strip placement mechanism, thereby implementing the one-by-one
delivery of the parting
strips 3'.
[0047] In order to reliably clamp the parting strips 3', as shown in FIG. 8,
telescopic posts 621
are provided at sides of the clamping plates 62 close to the parting strips
3', and the telescopic
posts 621 are elastically connected to the clamping plates 62. Specifically,
limiting holes 622 are
formed in the clamping plates 62. The telescopic posts 621 are provided in the
limiting holes 622.
Springs 623 are provided between the telescopic posts 621 and bottoms of the
limiting holes 622,
such that the telescopic posts 621 can be stretched out or retracted back
relative to the clamping
plates 62. When the clamping plates 62 get close oppositely to firmly press
the parting strips 3',
the telescopic posts 621 contact the ends of the parting strips 3' first. Any
telescopic post 621
corresponding to a longer parting strip 3' has a large retracting amount, such
that all parting strip
3' can be reliably clamped.
[0048] In order to clamp the parting strips 3' more reliably and prevent
clamped parting strips 3'
from turning over, as shown in FIG. 9, locating holes 41 extending inward to
the parting strips 3'
are formed in the ends of the parting strips 3'. The telescopic posts 621 can
be stretched into the
locating holes 41. Preferably, two or more telescopic posts 621 can be
stretched into each of the
parting strips 3'. With the horizontal arrangement of the telescopic posts
621, the parting strips 3'
keep horizontal. It is also proposed to design the rectangular telescopic
posts 621, such that the
8
CA 03163642 2022- 7- 4
Our Ref: 43970-19
CA National Phase of PCT/CN2021/111374
(FS2214P-CA-PCT)
single telescopic posts 621 stretched into the locating holes 41 can abut
against upper and lower
inner walls of the parting strips 3' to prevent the parting strips 3' from
turning over.
[0049] Similarly, in order to move the parting strips 3' up and down more
stably, as shown in
FIG. 6, elastic support posts 511 are provided at two sides of the lift plate
51. The elastic support
posts 511 are elastically connected to the lift plate 51. Support trays 512
are provided on tops of
the elastic support posts 511. The support trays 512 abut against bottom
surfaces of the parting
strips 3'. Each of the support trays 512 contacts a corresponding one of the
parting strips 3'. The
elastic support posts 511 are also connected to the lift plate 51 through
springs, such that the
elastic support posts 511 can move up and down relative to the lift plate 51,
a same vertical row
of the parting strips 3' are independently stressed in the lifting process of
the parting strips 3', and
the phenomenon that the parting strips 3' move up and down unsmoothly due to
mutual
squeezing and friction is prevented.
[0050] In order to deliver the framed parting strips 3' to the lift mechanism
5, referring to FIG. 6
and FIG. 10, the fully automatic framing machine for aluminum profiles in the
embodiment may
further include a parting strip frame conveyance mechanism 104. The parting
strip frame
conveyance mechanism 104 includes a conveyance slide rail 74 and a conveyance
slide block 75.
The conveyance slide block 75 is stretched between the lift mechanism 5 and
the layering
mechanism 6. The conveyance slide block 75 can be slidable on the conveyance
slide rail 74. A
bottom of the parting strip frame can be matched with the conveyance slide
block 75. The
parting strip frame can move on the conveyance slide rail 74 with the
conveyance slide block 75.
[0051] As shown in FIG. 12, the aluminum profile framing device 102 includes a
longitudinal
movement mechanism 1, a lateral movement mechanism 2, a vertical movement
mechanism 3
and a parting strip gripping frame 4. The longitudinal movement mechanism 1 is
configured to
drive the vertical movement mechanism 3 to move forward and backward. The
vertical
movement mechanism 3 is configured to drive the lateral movement mechanism 2
to move up
and down. The lateral movement mechanism 2 is configured to drive the parting
strip gripping
frame 4 to move left and right. The parting strip gripping frame 4 includes a
frame body 41.
Gripping claws 42 extending downward are symmetrically provided at two sides
of the frame
body 41.
[0052] In the embodiment, the parting strip gripping frame 4 is sequentially
connected to the
lateral movement mechanism 2, the vertical movement mechanism 3 and the
longitudinal
movement mechanism 1 to ensure the stable movement of the parting strip
gripping frame 4. The
lateral movement mechanism 2 for stretching a lower end of the parting strip
gripping frame 4 to
a bottom of each of the parting strips is in the last among the three movement
mechanisms.
Therefore, there are fewer components that need to move left and right, and
the parting strip
9
CA 03163642 2022- 7- 4
Our Ref: 43970-19
CA National Phase of PCT/CN2021/111374
(FS2214P-CA-PCT)
gripping frame 4 moves left and right more accurately and sensitively.
[0053] Referring to FIG. 13, the longitudinal movement mechanism 1 includes a
bracket 11, a
longitudinal guide rail 12, a longitudinal movement frame 13 and a
longitudinal drive
mechanism 14. The bracket 11 is stretched across an aluminum profile
discharging station l' and
a framing station 105. The longitudinal guide rail 12 is provided on the
bracket 11. The
longitudinal movement frame 13 is supported on the bracket 11, and can move
forward and
backward along the longitudinal guide rail 12. The longitudinal drive
mechanism 14 is
configured to drive the longitudinal movement frame 13 to move forward and
backward relative
to the bracket 11.
[0054] The longitudinal drive mechanism 14 includes a longitudinal drive motor
141, a first
synchronizing shaft 142, first synchronizing gears 143, and first racks 144 in
a same direction as
the longitudinal guide rail 12. The first racks 144 are provided on the
bracket 11. The
longitudinal drive motor 141, the first synchronizing shaft 142 and the first
synchronizing gears
143 are arranged on the longitudinal movement frame 13. The synchronizing
gears are provided
at two ends of the synchronizing shaft 142. The first synchronizing gears 143
are meshed with
the first racks 144. The longitudinal drive motor 141 is configured to
rotationally drive the first
synchronizing shaft 142. When the longitudinal movement frame 13 is
necessarily driven to
move forward and backward, the longitudinal drive motor 141 rotationally
drives the first
synchronizing gears 143 through the first synchronizing shaft 142. As the
first racks 144 fixed on
the bracket 11 rotate with the first synchronizing gears 143, the longitudinal
movement frame 13
moves forward and backward relative to the bracket 11. The longitudinal guide
rail 12 provides a
guiding function for the longitudinal movement frame 13.
[0055] As shown in FIG. 14, the vertical movement mechanism 3 includes a
vertical guide post
31, a vertical guide sleeve 32, a vertical movement plate 33 and a vertical
drive mechanism 34.
The vertical guide sleeve 32 is provided on the longitudinal movement frame
13. The vertical
movement plate 33 is provided at a lower end of the vertical guide post 31.
The vertical guide
post 31 is nested in the vertical guide sleeve 32. The vertical drive
mechanism 34 is configured
to drive the vertical guide post 31 to move up and down relative to the
longitudinal movement
frame 13.
[0056] The vertical drive mechanism 34 includes a lift drive motor 341, a
second synchronizing
shaft 342, second synchronizing gears 343, and second racks 344. The lift
drive motor 341, the
second synchronizing shaft 342 and the second synchronizing gears 343 are
arranged on the
longitudinal movement frame 13. The second racks 344 are fixedly connected to
the vertical
movement plate 33. The second synchronizing gears 343 are provided at two ends
of the second
synchronizing shaft 342. The second synchronizing gears 343 are meshed with
the second racks

344. The lift drive motor 341 is configured to rotationally drive the second
synchronizing shaft
342. When the longitudinal movement frame 13 is necessarily driven to move up
and down, the
lift drive motor 341 rotationally drives the second synchronizing gears 343
through the
synchronizing shaft, thereby driving the second racks 344 to move up and down.
The
longitudinal movement frame 13 connected to the second racks 344 also moves up
and down
therewith. With the vertical guide post 31 and the vertical guide sleeve 32,
the longitudinal
movement frame 13 moves up and down more stably.
[0057] As shown in FIG. 16, the lateral movement mechanism 2 includes a
vertical movement
plate connecting frame 21, a lateral slide mechanism 22 and a lateral drive
mechanism 23. The
vertical movement plate connecting frame 21 is connected to the frame body 41
through the
lateral slide mechanism 22. The frame body 41 can move left and right relative
to the vertical
movement plate connecting frame 21. The lateral drive mechanism 23 is
configured to drive the
frame body 41 to move left and right relative to the vertical movement plate
connecting frame 21.
The vertical movement plate connecting frame 21 is fixedly connected to the
vertical movement
plate 33. Preferably, the lateral drive mechanism 23 may be a cylinder
connected to the frame
body 41 and the vertical movement plate connecting frame 21. The lateral slide
mechanism 22
may include a slide rail 221 and a slide block 222. Either the slide rail 221
or the slide block 222
is connected to the frame body 41, and the other is connected to the vertical
movement plate
connecting frame 21. When the frame body 41 is necessarily driven to move left
and right, the
cylinder is stretched out or retracted back, such that the frame body 41 moves
left and right
relative to the vertical movement plate connecting frame 21.
[0058] Referring to FIG. 15, the lift drive motor 341 as the component with
the maximum mass
in the whole vertical movement mechanism is crucial to the stability of the
longitudinal
movement frame 13 in operation. Preferably, the lift drive motor 341 is fixed
at a horizontal
center of the longitudinal movement frame 13 through a motor fixing frame 345,
such that a
center of gravity of the lift drive motor 341 is located at the horizontal
center of the longitudinal
movement frame 13. Therefore, during movement of the longitudinal movement
frame 13, the
longitudinal movement frame 13 moves more stably with less shaking of the
longitudinal
movement frame 13.
[0059] More preferably, in order that an overall center of the lift drive
motor 341 and a gearbox
matched with the lift drive motor 341 is located at a same height as the
longitudinal movement
frame 13, the motor fixing frame 345 is composed of two symmetrical U-shaped
rods. The lift
drive motor 341 and the gearbox 346 matched with the lift drive motor 341 are
arranged on the
U-shaped rods. With the above design, when a movement speed of the
longitudinal movement
frame 13 changes, the longitudinal movement frame 13 is not turned over for
the lift drive motor

341 and the gearbox 346 matched with the lift drive motor 341, and the
longitudinal movement
frame 13 can be stopped accurately at a predetermined position.
[0060] Preferably, as shown in FIG. 17, the gripping claws 42 each include a
connection rod
421 and a carrier plate 422 at a tail end of the connection rod 421. A
position sensor 411 for
sensing a position of the aluminum profile is further provided on the frame
body 41. A sensing
position of the position sensor 411 is as high as a position of the carrier
plate 422.
[0061] Preferably, a pressure sensor 412 is provided on the carrier plate 422
or at a junction
between the carrier plate 422 and the connection rod 421. The pressure sensor
412 is configured
to detect a pressure of the aluminum profile or each of the parting strips to
a bottom of the carrier
plate 422. When any parting strip is located at an inaccurate position, the
carrier plate 422
moving down may press the parting strip. In this case, the pressure sensor 412
senses the
pressure and can give an alarm and control the system to shut down, for fear
of the snap of the
parting strip or damage to the carrier plate 422, etc.
[0062] Descriptions will be made below in detail to the working principle in
the embodiment:
[0063] I. Taking-out and placement of the parting strips
[0064] 1. The framed parting strips 3' are placed on the conveyance slide
block 75, and the
parting strip frame slides to the lift mechanism 5 along the conveyance slide
rail 74.
[0065] 2. The leadscrew drive mechanism 53 of the lift mechanism 5 drives the
lift leadscrew
52 to move up. The lift plate 51 on the lift leadscrew 52 pushes the bottoms
of the parting strips
3' to move up the parting strips 3' overall.
[0066] 3. When the uppermost layer of the parting strips 3' reaches a
predetermined height, the
clamping plates 62 are stretched out under the pushing of the clamping
cylinder 61 to clamp and
fix the uppermost layer of the parting strips 3'.
[0067] 4. The lift mechanism 5 drives remaining parting strips 3' to move
down, such that the
uppermost layer of the parting strips 3a' are separated from the remaining
parting strips 3b'.
[0068] 5. The guide rails 71 are stretched out under the driving of the guide
cylinder 72. The
guide rails 71 are located between the uppermost layer of the parting strips
3a' and the parting
strips 3b' thereunder. The layering mechanism 6 releases the uppermost layer
of the parting strips
3a', such that the uppermost layer of the parting strips 3a' are carried on
the guide rails 71.
[0069] 6. Referring to FIG. 19, the push motor rotationally drives the
chainwheel 732, such that
the chain 733 on the chainwheel 732 rotates therewith. The push claw 734 on
the chain 733
contacts the uppermost layer of the parting strips 3', and pushes the parting
strips forward along
the guide rails 71. Whenever the push assembly 73 pushes the uppermost layer
of the parting
strips 3' by a distance equivalent to a width of one parting strip 3', the
endmost parting strip 3' on
the guide rails 71 falls onto the feeding conveyor belt 5' of the parting
strip placement

mechanism, thereby implementing the one-by-one delivery of the parting strips
3'.
[0070] The solution can separate and deliver the parting strips 3' one by one.
With the stable and
reliable operation, and the high storage density of the parting strips 3', the
present disclosure can
meet the use requirements on the parting strips 3' for a long time after
adding one frame of the
parting strips 3'.
[0071] II. Delivery and framing of the aluminum profile
[0072] 1. The feeding conveyor belt 5' of the parting strip placement
mechanism conveys the
parting strips at a predetermined distance to be below the aluminum profile to
be delivered.
[0073] Referring to FIG. 18, in an initial state, the carrier plate 422 is
located above the
aluminum profile discharging station l', and the vertical movement mechanism 3
drives the
carrier plate 422 to move downward. When moving to be below the parting strips
3', the carrier
plate 422 is driven by the lateral movement mechanism 2 to translate toward
the parting strips,
such that the carrier plate 422 is located below the parting strips 3'.
[0074] 2. While the vertical movement mechanism 3 drives the carrier plate 422
to move up, the
parting strips 3' and the aluminum profile 4' on the parting strips 3' move
up, either.
[0075] 3. Once being in place, the parting strips 3' and the aluminum profile
4' are delivered by
the longitudinal movement mechanism 1 to the framing station at a side of the
aluminum profile
discharging station. There is a material frame 2' at the framing station 105.
[0076] 4. The vertical movement mechanism 3 drives the carrier plate 422 to
move down. When
the parting strips 3' and the aluminum profile 4' are delivered to the
material frame, the carrier
plate 422 is separated from the parting strips 3'. The lateral movement
mechanism 2 drives the
carrier plate 422 to translate toward a direction away from the parting
strips, and the carrier plate
422 leaves away from the parting strips 3'.
[0077] 5. The carrier plate 422 is restored to deliver a next batch of
aluminum profiles.
[0078] The descriptions above are preferred implementations of the present
disclosure. It should
be noted that for a person of ordinary skill in the art, various improvements
and modifications
can be made without departing from the principles of the present disclosure.
These
improvements and modifications should also be regarded as falling into the
protection scope of
the present disclosure.
