Intelligent copying heat transfer printer specialized for cues
Technical Field:
The present invention relates to a heat transfer printer, especially to an
intelligent copying heat transfer printer, which belongs to the technical
field
of special surface printing technical equipment.
Technical Background:
Heat transfer printing devices refer to all the devices using heat transfer
printing
technology, which include the planary surface pyrograph machine, the high
pressure
pyrograph machine, GB¨HB, the baking cup machine, the baking machine, the
roast
cap machine and other transfer printing devices. The printing scope includes
planary surface pyrograph as well as curved surface pyrograph for quilts,
plates
or hats, which is a new technology. Heat transfer printing technology is to
print
designs onto thermotolerant paper, and to print designs onto finished
materials
via adding heat and pressure. As a new surface printing technology, the heat
transfer technology has been widely applied in a variety of fields due to its
creative design, low requirements for printing, abundant colors of the
designs,
and environment friendly manufacture procedure. The traditional heat transfer
printing technology aims mainly at printing onto a planary surface, an
inclined
plan, a circumference surface, a regular curved surface or a male and female
surface
with a small radian and other single¨surface products. However, the
traditional
heat transfer technology cannot achieve a single time heat transfer processing
onto
an elongated formed product or the whole surface of the product.
The heat transfer printing device in the prior art can achieve printing onto
the
whole surface of an elongated product (such as a cue). However, such a machine
is
manually operated and features a low degree of intelligence. In addition,
according
to different products, the action, position, direction and pressure needed of
different stages are all different. The heat transfer printing device in the
prior
1

art cannot regulate the motion of the different stages and therefore cannot
achieve
accurate control of the heat transfer printing. Furthermore, the product
loading
and unloading are both manually operated, which is of low efficiency and labor
intensive.
Content of the Invention:
The goal of the current invention is to overcome the above mentioned
disadvantages

the
screw. Along the water flow direction within said main frame of the printer,
there
are sequentially located the heat transfer film automatic positioning device,
the
heat transfer positioning device, the heat transfer side sticking device, the
heat
transfer closing device, and the heat transfer pressure device, and the main
frame
of the printer is at one end furnished with the automatic cue releasing
device,
the automatic cue fetching and clamping device and the cue fetching machine
arm,
wherein the automatic cue releasing device is for the automatic release of the
cues,
the automatic cue fetching and clamping device is to clamp the cues which have
been
released by the automatic cue releasing device, and the cue fetching machine

to
realize the heat transfer printing process. And said heat transfer printer
applies
infrared heating.
Furthermore, said cue transmission device is a wheel gear driven chain.
Furthermore, the bottom of the cue clamping and fixing device is furnished
with
a sliding block which cooperates with the screw.

Furthermore, said cue clamping and fixing device is provided with a pressure
sensor.
Furthermore, the intelligent copying heat transfer printer further comprises
infrared temperature sensor for a timely detection and feedback regulation of
the
cue temperature during the whole processing procedure.
Furthermore, the cue fetching machine arm is a software controlled automatic
machine arm.
The advantage of the current invention lies in that: the current invention
features
a simple structure and effectively solves the problem of the prior art that
the
whole surface of an elongated object cannot be transfer printed by the
traditional
heat transfer printer. The effect and efficiency are better than water
transfer
printing. The transfer printed product looks beautiful and high quality. The
transfer printing applies a servo motor and is achieved using CAD copying
according
the shape of the cue, which leads to a more accurate transfer printing and the
pressure is more even. The printer of the current invention achieves the
regulation
of the action, position, direction, times, time and pressure of different
stages
via controlling the electricity box and adjust different parameters in
accordance
with different products. The transmission device uses the servo motor to
achieve
controlling in order to guarantee a more speedy and a more accurate feeding.
The
automatic feeding utilizes infrared electric eye to perform orientation so
that
the positioning is more accurate and faster, which prevents the manual
operational
mistakes. The heat transfer printing of the present invention utilizes
infrared
heating method, which is fast in heating and avoids heat loss during transfer
printing. This renders a more stable temperature during the transfer. In
addition,
the present invention applies automatic mechanic arm for loading and
unloading,
which reduces labor intensity.
