Film slitting device based on high polymer material

The utility model discloses a thin film slitting device based on a high polymer material, particularly relates to the technical field of thin film slitting, and aims to solve the problems that the existing thin film is unstable in rolling and easy to fall off during slitting, and the existing thin film cannot meet the requirements of slitting with different distances and cannot meet the requirements of different enterprises. A cavity is formed in the lower roller, an abutting assembly is arranged on the lower roller and comprises a rotating shaft, the rotating shaft rotationally penetrates through the lower roller and is rotationally connected between the interiors of the lower roller, a rotating handle is fixedly connected to one end of the rotating shaft, and a plurality of first bevel gears are arranged on the outer wall of the rotating shaft; the outer walls of the multiple first bevel gears are connected with two second bevel gears in a meshed mode. According to the film winding device, the film winding
