Description

Technical Field

[0001] The utility model relates to the technical field of film material processing, in particular to an upper and lower double cutting knife mechanism of a winding machine. Background Art

[0002] In the existing film winding equipment, especially the coating machine, after the film processing is completed, the film is wound up to form a roll-shaped winding structure. After the winding is completed, the film material needs to be cut to separate the wound film material from the subsequent film material. The prior art commonly uses a single-side trimming method to cut the film material. Then, due to changes in the production process and changes in the film material processing surface, the winding direction of the film material of the winding equipment changes. Therefore, it is necessary to reinstall and adjust the position of the cutter, resulting in low production efficiency. In addition, the existing cutter moves in a straight line, which makes its cutting effect on the film poor and prone to adhesion. Utility Model Content
