The cutter mechanism 30 comprises a cutter 31 and a connecting member 32, wherein the cutter 31 is located at an end away from the guide post 20, and the cutter 31 is vertically connected to the guide post 20 through the connecting member 32. In addition, a heating element 33 for heating the cutter to a predetermined temperature is arranged in the connecting member 31, so that when the guide post 20 drives the cutter 31 to rotate, the cutter 31 with a predetermined temperature can cut into the membrane surface to a predetermined depth. In this way, after the membrane is rolled up in its entire width, the guide post 20 can be directly rotated, and the cutters evenly spaced and distributed on the guide post 20 can be heated to a predetermined temperature. The knife 31 cuts the finished coils into small widths online, and there is no need to transfer them to the slitting and rewinding machine for unwinding and slitting, which can simplify the operating steps and improve work efficiency. It can also reduce the contact frequency between the film and the equipment, thereby reducing the probability of scratching or scratching the film, and can improve the yield of the film to a certain extent. In addition, especially for films with high Tg, cold cutting is more likely to cause incision defects, burrs, hair chips and other problems, resulting in a low overall yield. By pre-heating the cutter 31 to a suitable temperature through a heating element, various problems caused by cold cutting can be effectively avoided when the knife is fed into the strips.

This meshing transmission method has higher transmission accuracy and can ensure the stability of feeding and retracting.
