[0029] When the air valve membrane moves between the film placing roller 3 and the guide roller 5, the pointed cone head 13 is inserted between the two air valve membranes, which has a separation effect on the two air valve membranes to prevent them from sticking together. When the air valve membrane moves in contact with the surface of the separation plate 12, the friction force drives the rotating column 16 to rotate along the rotating shaft 17, thereby reducing the contact area, reducing the friction force, and avoiding surface damage caused by large-area friction, thereby improving the safety of the air valve membrane. The separation plate 12 moves along the moving groove 18 to adjust the distance between the separation plate 12 and the air valve membrane, so that it is suitable for air valve membranes of different sizes and improves flexibility.
