After the diaphragm 100 on the first winding roller 32 is cut, the two rotating cylinders 53 of the abutting assembly 70 are used for abutting the end part of the diaphragm 100 to move to the second winding roller 42, so that the end part of the diaphragm 100 is forced to be sleeved on the plurality of positioning short needles in the two needle inserting areas, and the plurality of positioning short needles are used for puncturing and fixing the end part of the diaphragm 100. The two rotary drums 53 are further configured to press the positioning short pins to descend so as to partially enter the second winding roller 42, and the second winding roller 42 is configured to drive the film 100 to rotate through the positioning short pins so as to wind the film into a second film roll.
