Description

Technical Field

[0001] This utility model relates to the field of PVC film winding, specifically to a high-efficiency winding mechanism for PVC film calendering. Background Technology

[0002] The PVC film production process requires calendering, which is a process in which heated compound rubber or PVC rubber is passed through the gap between two horizontally arranged rollers that rotate relative to each other to form semi-finished products such as film. After calendering, the PVC film is wound up and stored by winding rollers to make the collection of calendered PVC film more convenient.

[0003] For example, Chinese patent application No. 202221218347.X provides a film taking-up mechanism for a PVC film calender. This technical solution involves inserting one end of the PVC film between two guide rollers and then fixing one end of the PVC film to the outer wall of the take-up roller. As the thickness of the PVC film on the outer wall of the take-up roller increases, the slide plate slides through the sliding groove, while the pressing roller presses the PVC film wound on the outer wall of the take-up roller. This solves the problem of wrinkles easily appearing on the PVC film when it is wound by the take-up roller in the prior art, avoids creases on the outer wall of the wound PVC film, and improves the convenience of PVC film winding.

[0004] However, the following problems still exist in this technical solution: the PVC film is wound up by a take-up roller, but the length of the take-up roller in this device is fixed and cannot be adjusted according to the width of the PVC film, which has certain limitations.

[0030] Rotate the limiting plate 406 to extend it from both ends of the connecting rod 3, insert the take-up rollers 401 of different lengths onto the outside of the connecting rod 3, and then rotate the limiting plate 406 into the inside of the connecting rod 3. Move the two limiting frames 402 to both sides of the take-up roller 401, and rotate the first bolt 405 into the second threaded hole 404 and the first threaded hole 403. Fix the limiting frame 402 onto the connecting rod 3 with the first bolt 405. This utility model can fix take-up rollers 401 of different widths onto the connecting rod 3 through the limiting mechanism 4, so as to roll up PVC films of different widths and expand the scope of application of this utility model.
