Full-automatic biaxially oriented polypropylene film bag making machine

The utility model belongs to the technical field of bag making machines, and particularly relates to a full-automatic biaxially oriented polypropylene film bag making machine which comprises a device body, a baffle is arranged on the side wall of the device body, a circular groove is formed in the top end of the baffle, and a roller is placed on the inner wall of the circular groove. A friction force reducing mechanism and an ejection mechanism are arranged below the roller, the friction force reducing mechanism comprises a pulley arranged below the roller, and a first connecting rod is installed on the side, close to the baffle, of the pulley. The roller can be ejected out of the inner wall of the circular groove by rotating the circular groove, so that the roller can be conveniently taken out, and the problems that when a traditional device is used, due to the fact that too many and heavy roller collecting bags are adopted, the roller is difficult to lift up from the device when being taken out, and meanwhi
