The coating assembly A applies resin to the upper surface of the lower film in the working state. The upper film conveying assembly is connected to the frame 1, and the upper film conveying assembly includes an upper film roller 9, which is movably connected to the frame 1, and the frame 1 is provided with an upper film guide roller 10 for guiding the upper film on the conveyor belt 4, so that the upper film is placed on the lower film along the middle of the conveying assembly and conveyed to the discharge end.
