At the same time, PVC film is also widely used in many fields such as building materials, packaging boxes and medicine. When producing PVC film, a calender is needed to press the PVC film. The calender can make the multi-layer PVC film bond more tightly. After the calender presses the PVC film, a winding mechanism is needed to rewind the PVC film.

The existing film winding mechanism does not adapt to different inner diameters and lengths, which leads to reduced production efficiency during the use of this type of structure. A film winding mechanism for PVC calendered film has been introduced specifically; therefore, the above problems need to be improved. Utility Model Content
