High-efficient waste silk pulverizer

The utility model discloses a high-efficient waste silk pulverizer. The pulverizer comprises a rack (1) and a main shaft (2), wherein the main shaft (2) is rotationally mounted on the rack (1) through a bearing; multiple groups of moving cutting blade structures are arranged on the outer periphery of the main shaft (2) in the axial direction; multiple fixed cutting blade structures are arranged at the positions, on the two sides of the main shaft, of the main shaft in the axial direction; a cover body (8) mounted on the main shaft (2) and the outer parts of the fixed cutting blade structures in a sleeving manner is further arranged on the rack; a discharging slanting plate (10) is arranged on the rack positioned at the lower part of the main shaft. The pulverizer has the benefits that the smashing effect is improved greatly; the time for smashing waste silks with the same amount is shortened; as the rigidness and the wearing resistance of the blades are improved and the blades can be reground and are adjustable in mounting position, the time for maintaining and repairing the device is reduced, and the problems in the prior art that the blades are low in smashing effect and the power source is waste after the cutting edges are worn are solved.
