When the raw material falls downward to the anti-blocking component 43, the rebound spring 432 can provide a buffer to slow down the speed at which the raw material falls downward. When the amount of raw material is large, the raw material accumulates on the filter plate 433. Under the influence of gravity, the raw material drives the filter plate 433 to move downward, and the filter plate 433 compresses the rebound spring 432 downward. During the downward movement of the filter plate 433, the distance between the edge of the filter plate 433 and the feeding pipe 41 becomes larger, and part of the raw material moves downward along the gap between the filter plate 433 and the feeding pipe 41 to the inside of the housing 3;
