This diaphragm pressing machine, which is specially used for manufacturing protective films, is placed on the lower pressing assembly through the setting of the dual-axis motor and the motor. When the dual-axis motor is turned on, the bevel gear 2 drives the bevel gear 1 to rotate, the bevel gear 1 drives the screw 2 to rotate, the screw 2 drives the slide 1 to move, and the slide 1 drives the cross bar to move vertically. When the motor is turned on, it drives the screw 1 to rotate, which reduces the time used to replace the protective film, improves the pressing efficiency, and increases the production capacity.

[0004] Traditional protective film laminating machines are difficult to control. After laminating, the laminating structure will rise quickly, resulting in poor lamination between the protective film and the product. Therefore, it is urgent to design a protective film laminating machine to solve the above problems. Utility Model Content
