[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses an elastic material for the anti-stick pad, which can adapt to waste materials of different thicknesses. Through elastic deformation, it tightly adheres to the application material, preventing the waste material from slipping or breaking during the peeling process. Combined with the flexible characteristics of the adhesive strip, it can actively adhere to the edge of the waste material. With the rotation of the peeling roller, a stable traction force is formed, ensuring that the waste material is completely peeled off from the application body, reducing waste material residue, making the waste material less prone to breakage, and effectively improving the stability of waste material peeling and the quality of the finished product.

[0017] 2. This utility model also utilizes the diamond-shaped locking strip of the locking strip and the diamond-shaped locking groove of the anti-stick pad to form a multi-directional locking mechanism, preventing the pad from falling off during high-speed rotation.

[0033] Working principle: This embodiment provides a waste stripping device for a coating die-cutting machine. First, the anti-stick pad 5 is installed in the mounting groove 401 of the fixed roller 4 by snap-fit ​​and fixed by the locking strip 6. Its surface is elastic and the material is non-stick, such as silicone or Teflon, to prevent waste from sticking to the roller surface. The diamond-shaped locking strip 602 of the locking strip 6 is inserted into the diamond-shaped locking groove 501 of the anti-stick pad 5. With the locking of the limiting protrusion 505 and the limiting groove 603, it is ensured that the anti-stick pad 5 will not fall off when the roller surface rotates at high speed. The cooperation between the elastic hole 503 and the wave spring 504 can improve the elasticity around the diamond-shaped locking groove 501, which facilitates the engagement or separation of the diamond-shaped locking groove 501 and the diamond locking strip 602. This can press against the finished product when in contact. The adhesive strip 7 is made of flexible material (such as rubber or adhesive material) and is fixed to the surface of the fixed roller 4 by the positioning groove 402 and the T-block 8. Its surface adhesiveness can adsorb the edges of waste materials. When the conveyor belt moves the waste materials, the edges of the waste materials come into contact with and are adhered to the adhesive strip 7. As the peeling roller 2 rotates, the waste materials are gradually peeled off from the main body of the product. A winding structure can be installed on the top of the fixed frame 1 on both sides. By connecting with the end of the waste materials, the waste materials can be wound up. Under the action of the peeling roller 2, a stable tension can be maintained, so that the peeling roller 2 achieves a self-rotation effect when peeling off the waste materials. This can improve the continuity of peeling off the waste materials and make it less prone to breakage. Moreover, the modular design of the anti-stick pad 5 and the adhesive strip 7 can be disassembled and replaced individually without disassembling the peeling roller 2 as a whole, reducing maintenance costs and improving equipment utilization.
