[0030] When the material needs to be changed, the gear two 35 is driven to rotate by the motor one 34, the gear two 35 is engaged to drive the gear one 33, and then the T-shaped rod 31, the connecting sleeve 32 and the support plate 36 are driven to rotate, so that the material box 37 storing different materials is driven to rotate, and the corresponding bottom communication pipe 315 of the material box 37 is located directly above the discharge hopper 2, that is, the material changing process of the central feeding system is completed, and the material does not need to be replaced during shutdown, so that the work efficiency is improved.

[0031] As shown in the figure, Figure 2 , Figure 4 The output end of the motor one 34 is fixedly installed through the Z-shaped frame 1 and the inner surface of the gear two 35, and the number of teeth of the gear one 33 is three times that of the gear two 35.
