Description

Technical Field

[0002] Plastic film, as a widely used material, plays an important role in many fields such as agriculture, industry, and packaging. Efficient, stable, and precise winding and coiling devices are crucial in its production and use.

[0003] In the early days, the winding methods for plastic film were relatively simple and crude, usually using manual or semi-automatic methods. This was not only inefficient, but also difficult to guarantee the quality of winding, and the film was prone to problems such as wrinkles, loosening, and deviation. With the continuous development of industrial technology, some mechanically driven winding devices have emerged.

[0004] In the prior art, the winding roller of a plastic film winding device is generally fixed on the worktable, and the surface tension of the film is adjusted by a tension adjustment system. As a result, before the film is wound, wrinkles may easily appear on the surface of the film due to the guide roller or human factors, which may lead to quality problems in the finished film. Therefore, this application provides a plastic film winding device to meet the requirements. Utility Model Content

[0027] like Figures 1 to 4 As shown, the winding section includes: a first support rod 9, mounted on one side of the sliding block 8, and configured to fix the first drive unit 2 by a bracket; a second support rod 10, mounted on the side of the sliding block 8 away from the first support rod 9; and a winding roller 11, mounted between the first support rod 9 and the second support rod 10, and configured to be driven to rotate by the first drive unit 2 to wind up the film.

[0028] Example 2: Figures 1 to 4As shown, the second support rod 10 includes: a support block 12, installed on the side of the sliding block 8 away from the first support rod 9; a fixing module, located on the top of the support block 12, used to fix the take-up roller 11, and configured to disassemble the take-up roller 11 after the fixing module is released from fixing the take-up roller 11, so as to remove the finished film; the fixing module includes a limiting rod and a limiting box, the limiting rod is installed in the limiting box, and both ends of the sliding block 8 are slidably connected to a set of limiting rods to limit the sliding block 8.

[0030] like Figure 3 As shown, it also includes: a circular groove, which is opened on the side of the circular block 14 near the first support rod 9, for placing the take-up roller 11.

A guide section 4 at the top of the workbench 1 guides the film with its surface tension adjusted, enabling it to move accurately toward the winding section.

The middle of the sliding block 8 is threadedly connected to the threaded rod 6, and both ends are connected to two sets of limiting modules 7. When the threaded rod 6 rotates, the sliding block 8 moves along... The threaded rod 6 moves horizontally, and the sliding block 8 drives the winding part away from or near the guide part 4, thereby changing the tension of the film surface to achieve the ideal winding state. When winding begins, the first drive part 2 on the winding part drives the winding roller 11 to rotate, thereby winding the film. When the winding is completed and the finished film needs to be removed, the fixing module is released, and the winding roller 11 can be disassembled. Specifically, after the rotating block 13 rotates away from the first support rod 9, the locking block 17 on the rotating block 13 is released from the locking groove 16 on the circular block 14, and at the same time, the hook block 18 on the rotating block 13 is released from the groove 19 on the circular block 14. Then the circular block 14 is removed, and the finished film is removed.
