Technical Field

[0001] This utility model relates to the field of ton bag production technology, and in particular to a winding device for ton bag production. Background Technology

[0002] Ton bags are flexible packaging containers widely used in industries such as chemicals, building materials, grains, and minerals. They are characterized by large capacity, convenient loading and unloading, and reusability. As industrial production demands increasing packaging efficiency and product quality, the production process of ton bags is constantly being improved and optimized. Among these, the winding device is a key piece of equipment in the production process of ton bags, and its performance directly affects product quality, production efficiency, and the convenience of subsequent processing.

[0003] However, existing ton bag winding devices still have some shortcomings and areas for improvement in actual use. Most existing winding devices are operated manually or semi-automatically, relying on human experience for tension adjustment and speed control, which makes it difficult to ensure product consistency and stability. At the same time, uneven material tension can cause wrinkles, deformation, or uneven stretching of the bag, affecting the appearance and performance of the bag. Therefore, those skilled in the art provide a winding device for ton bag production to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a winding device for producing ton bags. Through the installation of an auxiliary structure, the sidewall of the auxiliary roller adheres to the sidewall of the ton bag during winding. As the winding diameter increases, the connection between the connecting frame and the torsion spring and the retainer causes the connecting frame to tilt to one side. During this tilting process, the auxiliary roller remains in contact with the sidewall of the ton bag under the elastic action of the torsion spring, providing sufficient pressure and preventing wrinkles during winding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding device for producing ton bags, comprising a base, a mounting plate fixedly connected to the center of the upper surface of the base, a lifting device fixedly connected to the center of the upper surface of the mounting plate, a fixing plate fixedly connected to the output end of the lifting device, a worktable fixedly connected to the upper end of the fixing plate, a winding structure provided at the front edge of the center of the upper surface of the worktable, and an auxiliary structure provided at one edge of the center of the upper surface of the worktable near the winding structure.

[0006] The auxiliary structure includes a second slide groove, which is located at the center of the upper end face of the worktable near one side edge. A retainer is slidably arranged inside the second slide groove. A connecting frame is arranged at the center of the upper end face of the retainer. The two ends of the connecting frame are rotatably connected to the two inner side walls of the retainer.

A connecting plate is respectively provided on the output end of the second telescopic device and the output end of the drive motor. The take-up roller is disposed between the two connecting plates.

[0009] With the above technical solution, in use, the slider inside the first slide groove is slid to one side by controlling the first telescopic device, and then the take-up roller is installed on the side wall of the connecting plate on the output end of the drive motor. Then, the first telescopic device is controlled to drive the slider to slide to the other side, and then the third telescopic device drives the placement plate to lift and lower, and the connecting plate on the output end of the second telescopic device is snapped onto the other side wall of the take-up roller, so that it can be disassembled and replaced according to the winding situation.

[0010] Furthermore, the connecting plate on the front side is fixedly connected to the output end of the drive motor, while the connecting plate on the rear side is rotatably connected to the output end of the second telescopic device.
