It also has automated functions such as automatic feeding and unloading, which can significantly improve production efficiency and reduce production costs.

[0003] When workers need to punch plastic film, they place the plastic film on the punching equipment so that the equipment can punch it. However, during use, existing punching equipment may cause the plastic film to detach from the processing machine when the equipment retracts the blade due to the influence of plasticizers or static electricity. This results in workers having to manually remove the plastic film that is stuck to the surface of the cutter. Utility Model Content
