[0002] In the eyes of industry insiders, plastic and plastic sheet are the same thing. Previously, domestic factories were all called plastic factories, while in Hong Kong, Macau and Taiwan regions, plastic factories were called plastic companies. Plastic is a high molecular compound polymerized from monomers through addition polymerization or condensation polymerization. Its anti-deformation ability is medium, between that of fibers and rubber, and it consists of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. Resin refers to a high molecular compound that has not been mixed with various additives. The term "resin" was originally derived from lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% - 100% of the total weight of plastic. The basic properties of plastic mainly depend on the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resin, containing little or no additives, such as plexiglass.

[0003] Currently, when plastic sheets are being produced and processed, they need to be trimmed. However, when using general trimming devices, the plastic sheets cannot be well fixed and moved, resulting in an impact on the trimming effect. Content of the Utility Model
