[0002] Heat transfer generally refers to pyrography, which is also called fire-brush painting. It is a traditional Chinese art treasure. It uses a hot iron to burn marks on objects. While controlling the temperature and strength of pyrography, it focuses on "the idea comes before the pen, and the pen takes shape". Heat transfer needs to be composed of ink, glue and film (release film). Many people on the market call blank release film heat transfer film, heat transfer film, but in fact, these are all release films; release film belongs to blank film, which is mainly suitable for various levels of heat transfer products of water-based / oil-based screen printing inks and various special heat transfers, thermal transfer printing substrates, etc.; usually, a release agent is applied on the film for the final tearing of products such as heat transfer / lettering film / decorative film, and in the production and processing of heat transfer film, it needs to be sheared and rolled up by cutting equipment.

In most of the existing equipment, the cutter is usually fixed and installed with bolts. The cutter will wear out after long-term use, which will affect the cutting effect and quality. Therefore, the cutter needs to be disassembled and replaced regularly. The above-mentioned cutter installation and fixing method makes it inconvenient to disassemble and affect its disassembly and replacement efficiency, is inconvenient to use, and has relatively poor practicality.

[0023] The working principle of the utility model is as follows: when it is necessary to disassemble and replace the cutter 8, the push handle can be pushed to drive the push rod 11 to move, so that the push rod 11 will drive the two connected baffles 12 to move synchronously, and the baffle 12 on one side stretches the spring 16, so that the baffle 12 will push the connecting rod 13, so that the connecting rod 13 pushes the connecting plate 14 connected thereto to move, so that the two connecting plates 14 move in the relative outer directions, and at the same time the connecting plate 14 will drive the connected plug post 15 to move synchronously, until the plug post 15 moves out of the outer side of the through groove, the cutter 8 and the connection block 10 can be separated from the slider 7, and then a new cutter 8 can be replaced for use, and when the cutter 8 is installed, the above steps are repeated. The plug post 15 is moved out of the groove to the outside of the groove, and then the connecting block 10 is inserted into the groove, and the force applied to the push handle is released, so that the baffle plate 12 on one side drives the push rod 11 to reset under the elastic force of the spring 16, so that the two baffle plates 12 drive the connecting rod 13 and then drive the connecting plate 14 to reset, so that the connecting plate 14 drives the plug post 15 to move, and the plug post 15 is inserted into the corresponding through groove on the connecting block 10, and the installation and fixation of the cutter 8 is completed, so that the cutter 8 can be quickly replaced and used conveniently; when cutting, the distance between the limit plates 26 and the distance between the two cutters 8 are adjusted in advance according to the width of the heat transfer film and the distance between the two cutters 8 according to the needs. By starting the motor 6 to drive the bidirectional screw 5 to rotate, the two sliders 7 can be synchronously driven to drive the cutter 8 to move relatively inward or outward, so as to change the distance between the two cutters 8; by twisting the handle to drive the connected bidirectional screw 25 to rotate, the two limit plates 26 can be synchronously driven to move relatively inward or outward, so as to adjust the position of the two limit plates 26 and change the distance between the two. After moving them to the appropriate position, cutting can be carried out. Under the action of the pulling force generated when the heat transfer film is rolled up, it passes between the pressure roller 1 20 and the pressure roller 2 24 and moves from under the cutter 8. By starting the hydraulic cylinder 3 to push the adjusting seat 4, the slider 7 is moved down, and the adjusting When the seat 4 moves downward, it will drive the transmission plate 23 to move synchronously. When the transmission plate 23 presses down the fixed rod 21, it will drive the guide rod 18 and push the mounting seat 19 and the pressure roller 1 20 to move downward. At the same time, the fixed rod 21 will cooperate with the support rod 17 to squeeze the spring 22. When the cutter moves to the cutting height position, the pressure roller 1 20 cooperates with the pressure roller 2 24 to just squeeze and position the passing heat transfer film, but does not affect the conveying and movement of the heat transfer film, so as to cooperate with the force of winding the heat transfer film to tighten the heat transfer film to avoid looseness affecting the cutting effect. At the same time, the limit plate 26 will limit and guide the passing heat transfer film, and at the same time, it will also cause the roller to press down and position the heat transfer film to avoid its displacement affecting the cutting quality, making it easy to use and more practical.
