[0002] PVC film is primarily composed of polyvinyl chloride (PVC), which is slightly yellow, translucent, and shiny. Its transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the amount of additives used, PVC is divided into soft and hard PVC. Soft PVC is flexible and tough, with a sticky feel. Hard PVC is harder than low-density polyethylene (LDPE) but lower than polypropylene.

The limiting effect of the winding drum is poor during installation, and it is easy to loosen and move during the winding process, which may affect the winding of the film, so it needs to be improved.

By rotating the threaded rod 8, the lifting frame 6 can be driven to move longitudinally, so that the pressure roller 7 can press the film during the winding process. When the winding roller 92 needs to be removed, the arc block 97 is driven to leave the slot 99 through the pull rod 98. At this time, the spring in the spring telescopic rod 94 rebounds and drives the winding roller 92 to move to the rear end. At this time, the groove 95 is misaligned with the slot 99, and then the winding roller 92 can be removed. The overall installation and disassembly are simple.
