The universal ball 205 at the top of the connecting rod 206 is installed at the eccentric shaft of the movable plate 210. When the movable plate 210 rotates, the connecting rod 206 flips in the vertical plane, driving the rotating plate to move up and down, which facilitates the amplitude adjustment of the vibration assembly 2.

Then, driven by the motor 5, the movable screw 8 moves the transfer component 1 on the surface of the storage funnel 3 along with the 3D printer. The transfer component 1 transports the granular material in the storage funnel 3 into the 3D printer. Then, according to the size of the granular material, the vibration component 2 is activated, and the granular material is transported evenly.
