In use, the raw material is conveyed to the bottom of the hot-cutting mold by the conveyor belt, the hot-cutting mold is heated by the heating mechanism, and the hot-cutting mold is pushed down by the cylinder to cut the raw material. During the cutting process, the pressure head first contacts the raw material, compresses the raw material, and then cuts it.

[0004] However, most existing molding machines are open-type, making the aprons susceptible to environmental dust contamination, affecting their cleanliness. Furthermore, the plastic film is easily wrinkled during transport, which in turn affects the molding quality of the aprons. Utility Model Content
