AI Technical Summary
During the rolling process, plastic film is prone to trapping air, causing air bubbles or wrinkles, resulting in a "loose inside and tight outside" phenomenon.
A plastic winding device to prevent loosening was designed. It uses a structure of bracket, tension roller, winding roller and pressure roller. The winding roller is squeezed by a counterweight to expel air and prevent air from being entangled.
This effectively prevents air bubbles or wrinkles from forming in the plastic film during the winding process, ensuring that the film roll is tight and uniform.
