Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically to a winding mechanism for preventing uneven winding of packaging film and a bag making machine. Background Technology

[0002] High-barrier polyethylene film and modified nano-shale powder film possess excellent flexibility, tensile strength, and tear strength, making them easy to process into various packaging forms, such as bags and bottles. Simultaneously, they also exhibit good abrasion resistance and puncture resistance, protecting the contents of the package from external physical damage. After processing, they require winding by a rewinding mechanism.

[0003] High-barrier polyethylene film and modified nano-shale powder film, due to their excellent flexibility and tensile strength, are prone to uneven winding during the winding process after bag making. This unevenness not only makes the packaging film susceptible to physical damage during winding, such as minor tears, scratches, and even local deformation, but also greatly reduces the overall processing quality of the film material, affecting the subsequent storage and use efficiency of the product. Optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a winding mechanism and bag making machine for preventing uneven winding of packaging film, so as to solve the problem mentioned in the background art that flexible film materials are easily stretched during winding, resulting in uneven winding and affecting the subsequent storage and use of products.

[0028] The actuating guide assembly includes a guide frame 17, which is mounted on the top of the fixed connecting plate 2, and an actuating rod 20 is connected to the inner side of the guide frame 17. The actuating guide assembly is used for the transmission and guidance of the film roll.

[0029] Specifically, such as Figure 3 As shown, the top and front sides of the winding support frame 1 are connected to side baffles 12, and the top inner side of the side baffles 12 is provided with a guide plate 13. The bottom end of the guide plate 13 is connected to an installation adjustment block 14. The installation adjustment block 14 is provided with an arc-shaped installation groove, which can install the guide plate 13 within a certain range according to actual needs.

[0030] Specifically, such as Figure 3 As shown, an elastic extrusion rod 15 is connected to the inner side of the guide plate 13, and a lower pressure plate 16 is connected to the bottom end of the elastic extrusion rod 15. The lower pressure plate 16 is pressed against the top of the film roll to prevent transmission jitter.

[0031] Specifically, such as Figure 4 As shown, an elastic extrusion rod 18 is connected to the inner side of the guide frame 17, and a rotating connecting plate 19 is connected to the bottom end of the elastic extrusion rod 18. A toggle rod 20 is connected to the inner side of the rotating connecting plate 19.
