A large amount of raw materials can be pre-stored in the storage hopper 7. When it is necessary to feed materials, it can overcome the elasticity of the top support spring 10 and press down on the front part of the feeding cylinder 6. It is constrained by the hinge shaft 4 through the hinge frame 5. When the outer side of block 3 moves, the front of the feeding cylinder 6 is lowered. Under the connection of the connecting frame 11, the pressing plate 12 acts on the switch button box 13 to energize the electric conveying mechanism, which conveys part of the raw material in the storage hopper 7 into the feeding cylinder 6 and discharges it through the discharge pipe 19. When the external force is removed, the top support spring 10 elastically resets, the elastic top support on the front of the feeding cylinder 6 and the pressing plate 12 disengage from the switch button box 13, the switch button box 13 is in the off state, the electric conveying mechanism does not run, and only the raw material on the top of the picking platform 9 can be picked up.

[0025] The electric conveying mechanism includes a drive motor 14, a connecting shaft 15, and a spiral blade 16.
