Knife roller for crusher

Abstract

The invention discloses a knife roller for a crusher. The knife roller comprises a knife shaft, movable knives and a plurality of movable knife holders, wherein the plurality of movable knife holders are arranged in sequence along the axial direction of the knife shaft, and each movable knife holder sleeves the outer surface of the knife shaft and is fixedly connected with the knife shaft; a plurality of movable knives are arranged on each movable knife holder, and the plurality of movable knives are arranged at intervals around the axial circumference of the knife shaft; and the connecting line of one of the movable knives on all the movable knife holders is in a C shape along the axial direction of the knife shaft. According to the knife roller for the crusher, the connecting line of one of the movable knives on all the movable knife holders is in the C shape along the axial direction of the knife shaft, i.e. when the knife shaft rotates, only one movable knife on every movable knife holder is sheared with a stationary knife on a shredder, and therefore, in the process that the knife shaft continuously rotates, all the movable knives are successively cut with the stationary knife, so that continuous shearing of the knife roller in the circumferential direction can be realized, the cutting force is large, materials with high hardness are easy to crush, and energy consumption is reduced in the condition of equivalent materials.

Description

technical field [0001] The invention relates to the technical field of material processing equipment, in particular to a cutter roll for a crusher. Background technique [0002] With the development of science and technology, people's requirements for environmental protection are getting higher and higher. The waste generated in life is generally crushed by a crusher before subsequent treatment for recycling. The crusher mainly includes a crushing chamber, a rotating knife roller and a fixed knife fixed in the crushing chamber. The material is cut through the shearing action between the rotating knife on the knife roller and the fixed knife to achieve the purpose of crushing. However, the existing cutter roller structure used in crushers has insufficient cutting force and low cutting efficiency. When crushing materials with high hardness, it is easily damaged by the impact of the material, and the entire cutter roller consumes a lot of energy. Contents of the invention ...
