TECHNICAL FIELD
[0001] The utility model relates to the production technical field of BOPP film, specifically to a trimming machine for BOPP film production. BACKGROUND
[0002] BOPP film (biaxially oriented polypropylene film) is widely used in packaging, printing and other fields due to its excellent performance. However, during the production process of BOPP film, due to the limitations of extrusion and stretching processes, the edges of the film often have uneven thickness and burrs, which affect product quality and subsequent processing. Therefore, a trimming machine is needed during BOPP film production to trim the edges of the film.
[0003] The existing trimming machine lacks automatic waste recycling function when trimming BOPP film, so manual operation is still needed to recycle the trimmed waste. Moreover, the cutting tool of the existing trimming machine cannot guarantee stable trimming precision when trimming BOPP film, which may cause problems such as burrs and uneven cutting edges.
