Although this operation method can stably coat the glue on the base layer film, the amount of glue coated cannot be guaranteed. Usually, there is excessive glue on the base layer film. In the subsequent composite process, the glue will overflow to the surface of the composite film, affecting the surface quality of the finished composite film, and its stability is relatively poor.

[0008] Specifically, the driving member drives the lifting plate to move, and the lifting plate moves up and down smoothly under the action of the guide structure.

[0009] Since the lifting plate is connected to the driving member and the connecting rod with the glue discharging cylinder at the same time, when the lifting plate is lifted or lowered, a plurality of glue discharging cylinders will also be lifted or lowered together.
