[0027] Furthermore, in order to limit the position of the SMC sheet and facilitate the removal of the protective film on the surface of the SMC sheet and its adsorption onto the semi-circular adsorption roller 4, a vertical rod 15 is fixedly connected to the side of the push plate 12. One end of the vertical rod 15 passes through the film-tearing mounting frame 2 and extends to the top of the film-tearing mounting frame 2. The front and rear sides of the top of the film-tearing mounting frame 2 are provided with through grooves that are compatible with the vertical rod 15. A connecting rod 16 is fixedly connected to the end of the vertical rod 15 that extends to the top of the film-tearing mounting frame 2.
