Description

Technical Field

[0001] The utility model relates to the field of packaging bag film processing, and particularly relates to a device for winding waste materials at the edges of a film. Background Art

[0002] During the production and processing of a film, it is necessary to cut both sides of the film to trim the irregular sides to meet the required dimensions. The waste materials cut from the edges are generally wound synchronously by a winding machine. For example, a plastic film edge material winding machine disclosed in a Chinese utility model patent application with the patent application number 2017217130317 includes a frame. At the left and right ends of the frame, side plates that can slide along the frame and a driving mechanism are oppositely arranged. At the inner side wall of the side plate, a left chuck is connected through a bearing. At the rotating shaft of the driving mechanism, a right chuck matching the left chuck is fixedly arranged. A winding cylinder is movably clamped and fixed between the left chuck and the right chuck. This patent replaces the existing winding method with a rotating shaft passing through by adopting a sliding clamping method, thereby realizing the rapid loading and unloading of the edge material winding cylinder.

[0003] When loading and unloading the edge material winding cylinder in the above-mentioned prior art, it is necessary to rely on manual operation to hold one side plate with one hand and push it left or right to take out or clamp the edge material winding cylinder. This is not only time-consuming and laborious, but also, by the method of holding one side plate with one hand to clamp the edge material winding cylinder and then tightening the fastening screw at the positioning slider with the other hand, it is easy to leave gaps between the two ends of the edge material winding cylinder and the left and right chucks, resulting in left and right shaking of the edge material winding cylinder during operation and rotation. If two people cooperate in the operation, it will waste labor and cause high production costs. Content of the Utility Model
