The swing arm motor drives the swing arm to swing. With the circular motion of the swing arm, the movable ring is pulled and drives the connecting frame to move back and forth in the horizontal direction. The sieve plate moves back and forth quickly, scattering the caked material particles accumulated in the raw material box, ensuring the flowability of the material during filling, so as to facilitate subsequent weighing and filling.
