BLIND CUTTING MACHINE
BACKGROUND OF THE INVENTION
Field of Invention
The present invention relates to a blind cutting machine, in particular to a
cutting
machine having a cutting blade set with double cutting edges for cutting and
chamfering a
headrail, a slat group, and a bottom rail of a window blind, and capable of
cutting off a
venetian blind and/or a vertical blind.
Related Art
Generally, when a window blind manufacturer produces a venetian blind or
vertical
blind, the window blind is preset to several different sizes for being sold in
the market or
retail stores. When a consumer buys the window blind in the retail stores, the
window
blind is cut by a blind cutting machine in the store to the size matching the
window in the
house of the consumer, such that the consumer may install the window blind in
the house
by himself or by installers.
Main elements of a common window blind include a headrail, a slat group, and a
bottom rail, which are not necessarily made of the same material; for example,
the headrail
can be made of a relatively firm metal material, the slat group can be made of
a relatively
light aluminum material or PVC material, and the bottom rail is usually made
of the same
material as the headrail. When the elements made of the different materials
are cut, the cut
sections of the different materials have different appearances; therefore, the
headrail made
of the metal material should be cut with a die cutting blade, and the slat
group made of the
aluminum or PVC material should be cut with a blade made of a material
different from
that of the die cutting blade.

CA 02668804 2009-06-12
In a conventional blind cutting machine, for example, as disclosed in US
Patent No.
6,761,099 and US Patent No. 6,681,673, the elements of the window blind are
cut by a
single die cutting blade. As described above, the cut end surfaces are
unsatisfactory
inevitably. Therefore, two die cutting blades are needed on a cutting machine
respectively
cut the headrail and the slat group, so as to meet the special demand on the
cut end surfaces
of the slat group. Thus, the assembly complexity and the manufacturing cost of
the die
cutting blades are increased. Further, as the die cutting blades respectively
use different
driving sources or the same driving source, when the different driving sources
are used, the
cost of the driving sources are increased, and the operation is more complex.
Further, a blind cutting machine can cut only one type of the window blind,
and it is
impossible to cut the elements of two types of window blinds on the same blind
cutting
machine, such that in the limited space of the exhibition place, the usage of
the cutting
machine cannot be expanded.
In view of the above problems, the inventor proposes a blind cutting machine,
which
overcomes the defects of the prior art.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a blind cutting machine,
capable of
cutting off a venetian blind and/or a vertical blind, and having a cutting
blade set with
double cutting edges for cutting and chamfering on a headrail, a slat group,
and a bottom
rail of the window blind.
The present invention is further directed to a blind cutting machine, disposed
in an
exhibition place and capable of being operated to perform a cutting action.
In order to have a further understanding of the objectives and efficacies of
the present
invention, a detailed description is given below with reference to the

FIGs. 1, 2, and 3 are a three-dimensional view, a partial three-dimensional
view, and a
partial exploded view according to an embodiment of the present invention
respectively. A
blind cutting machine 1 of the present invention is used to cut a size of a
horizontal blind
(not shown) and/or a vertical blind (not shown), in which the horizontal blind
includes a
3
CA 02668804 2009-06-12
headrail and a slat group, and may further include a bottom rail, and the
vertical blind
includes a vertical headrail and a vertical slat group.
The blind cutting machine 1 according to this embodiment includes a table 2, a
first
cutting device 3, a first supporting base 5, and a second supporting base 6,
and may further
include a second cutting device 4.
The table 2 is a rectangular structure, and has a first end 21 and a second
end 22. A
measuring-rule 23 is disposed between the first end 21 and the second end 22
for measuring
a cut size when the horizontal blind or vertical blind is cut. In addition,
the elements of the
two window blinds are placed on the table 2 in a direction parallel to a major
axis direction,
and the elements of the window blinds can be shifted along the major axis
direction.
The first cutting device 3 is used to cut the horizontal blind (not shown), is
disposed on
the first end 21 of the table 2, and has a cutting blade die holder 31, a die
plate 32, and a
first driving mechanism 33.
The cutting blade die holder 31 is disposed on an outer side of the die plate
32, and the
first driving mechanism 33 is connected to the cutting blade die holder 31, so
as to drive the
cutting blade die holder 31 to shift towards a minor axis direction of the
table 2. The die
plate 32 has a first positioning region 321 and a second positioning region
322, such that
the elements of the horizontal blind and the vertical blind are respectively
positioned, in
which the elements include the headrail, the slat group, and the bottom rail
of the horizontal
blind, and the vertical headrail of the vertical blind. A first cutting blade
311 and a second
cutting blade 312 are disposed on the cutting blade die holder 31. The first
cutting blade
311 is disposed corresponding to the first positioning region 321, and has a
first cutting
edge 3111 and a second cutting edge 3112, so as to cut and chamfer (described
in detail
below) the elements of the horizontal blind penetrating the first positioning
region 321.
The second cutting blade 312 is disposed corresponding to the second
positioning region
322, so as to cut the elements of the vertical blind penetrating the second
positioning region
322.

CA 02668804 2009-06-12
The first positioning region 321 has a headrail positioning hole 3211, a slat
group
positioning hole 3212, and a bottom rail positioning hole 3213, and the
headrail, the slat
group, and the bottom rail of the horizontal blind respectively pass through
the holes and
are positioned. The bottom rail positioning hole 3213 is used for holding the
bottom rail of
the horizontal blind, and the headrail positioning hole 3211 is disposed above
the slat group
positioning hole 3212. The positioning holes 3211, 3212, and 3213 are arranged
in an L
shape. The headrail is arranged in a direction perpendicular to the bottom
rail/slat group,
that is, when the headrail pass through the headrail positioning hole 3211, an
U-shaped
opening of the headrail faces upwards. At the same time, when the slat group
pass through
the slat group positioning hole 3212, the slats are arranged in a direction
parallel to a
moving direction of the first cutting blade and perpendicular to the opening
direction of the
headrail. The first cutting edge 3111 of the first cutting blade 311 is used
to cut off the
headrail, the second cutting edge 3112 of the first cutting blade 311 is used
to cut off the
slat group or together with the bottom rail, and chamfer the slat group for
trimming.
FIG 4 is a partial perspective view of the first cutting blade region
according to the
embodiment of the present invention. The second cutting edge 3112 of the first
cutting
blade 311 is approximately in a U shape, and includes a chamfering portion
3113 and a
vertical cutting portion 3114. When the first cutting blade 311 is driven by
the first driving
mechanism 33, the first cutting edge 3111 and the second cutting edge 3112 are
moved at
the same time. The first cutting edge 3111 cuts the headrail (not shown)
penetrating the
headrail positioning hole 3211. The vertical cutting portion 3114 of the
second cutting
edge 3112 cuts the bottom rail (not shown) penetrating the bottom rail
positioning hole
3213 and the slat group (not shown) penetrating the slat group positioning
hole 3212.
When the vertical cutting portion 3114 cuts the slat group, as the corners of
the two sides of
the slat group are right angles, the chamfering portion 3113 chamfers the
right angles on the
two sides of the slat group, so as to modify and improve an appearance of the
slat group.
In a retail store, the size of a sales counter is limited, and the sales
personnel is mostly
female, who may perform the cutting; further, the matching between the space
for driving
5
CA 02668804 2009-06-12
the first cutting device and the size of the sales counter must be considered
as well.
Therefore, the first driving mechanism 33 is further connected to a first
handle 34 having a
rod portion 341 in an approximate U shape and a grip portion 342. The rod
portion 341
has a first end 3411 and a second end 3412, the first driving mechanism 33 is
connected to
the first end 3411 of the rod portion 341, and the grip portion 342 is
vertical, faces towards
a direction of the second cutting device 4, and is connected to the second end
3412 of the
rod portion 341.
The second cutting device 4 is used to cut the vertical blind (not shown), is
disposed on
the second end 22 of the table 2, and has a third cutting blade 41, a
positioning mechanism
42, and a second driving mechanism 43. The positioning mechanism 42 positions
the
element (that is, the vertical slat group) of the vertical blind, and the
second driving
mechanism 43 is connected to the third cutting blade 41, so as to drive the
third cutting
blade 41 to cut the element (that is, the vertical slat group) of the vertical
blind.
The positioning mechanism 42 is used to position the vertical slat group, the
third
cutting blade 41 is used to cut off the vertical slat group, and the second
positioning region
322 has a vertical headrail positioning hole 3221, such that the vertical
headrail is
positioned, and the first driving mechanism 33 drives the second cutting blade
312 of the
cutting blade die holder 31 to cut off the vertical headrail.
The second driving mechanism 43 is further connected to a second handle 44,
such that
a user applies a force to drive the second driving mechanism 43.
The first supporting base 5 is slidably disposed adjacent to the first cutting
device 3 and
corresponding to the first positioning region 321, and has a first supporting
recess 51, a first
bearing table 52, and a first supporting table 53. The first supporting recess

the headrail
and the slat group bear against the rotating part 63, and when the rotating
part 63 is turned
upwards to be perpendicular to the second bearing table 62, the vertical slat
group is placed
on the second bearing table 62.
In addition, if the size of the horizontal blind is relatively large, a third
supporting base
7 is further disposed between the first supporting base 5 and the first
cutting device 3. The
third supporting base 7 has a third supporting recess 71 and a third bearing
table 72. The
third supporting recess 71 is disposed corresponding to the slat group
