[0002] When laminating processed products, laminating equipment for plastic packaging products is often used. Plastic packaging products are used to wrap and hold various items such as food, electronic products, and daily necessities. Laminating equipment is a processing device that covers the surface of a substrate with a thin film. Its function is to improve the substrate's waterproof, scratch-resistant, and wear-resistant properties through lamination. In the production and processing of packaging products, laminating equipment can treat the substrate of packaging products with a film, allowing the processed packaging products to better meet the actual needs of product packaging and better fulfill their functions of protecting, storing, and transmitting information. In the prior art, some plastic packaging products are generally coated with a coating mechanism and a conveyor belt.
