[0026] Please refer to Figure 4Guide frames 14 are provided on both sides above the top plate 18, and a driving motor 15 is installed on the side wall of the guide frame 14. The output end of the driving motor 15 is connected to the material receiving component 13, and a driven shaft 16 is provided at one end of the material receiving component 13 away from the driving motor 15.
