[0002] PVC film is a common plastic film material, usually used in packaging, building materials, printing and other fields. The main component of PVC film is polyvinyl chloride, which has good weather resistance, chemical resistance and mechanical properties. PVC film processing generally uses a PVC film calender. The PVC film calender can process PVC resin or PVC particles into a film through heating, melting, extrusion and calendering. After the PVC film is processed by the PVC calender, the PVC film needs to be rolled up for easy transportation and storage.
[0003] As the winding roller continuously rewinds the PVC film, the thickness of the rolled PVC film on the winding roller will continue to increase, causing the pressure exerted on the PVC film by the pressing roller in contact with the PVC film to increase synchronously.
