Blade structure and knife roller of double-shaft shredding machine

Abstract

The invention discloses a double-shaft shredder blade structure, which includes a flywheel and several blades; the flywheel includes a flywheel body and several ratchets, and the several ratchet rings are arranged on the side wall of the flywheel body; The number of ratchets is equal to the number of blades; the blades are connected to the ratchets in a detachable one-to-one correspondence, and the bottom surface of the blades is matched with the front face of the ratchets, and the blades The sides of the ratchet are matched with the sides of the ratchet. The blade structure has good crushing effect, is convenient for replacement and maintenance, and has a simple structure. The invention also discloses a double-shaft shredder cutter roll, which has good working stability, convenient maintenance and good crushing effect.

Description

technical field [0001] The invention relates to the technical field of shredders, in particular to a blade structure and a knife roller of a biaxial shredder. Background technique [0002] Shredders are mainly used for crushing materials. The double-shaft shredder (also known as the shear shredder) is one of the shredders, which mainly reduces the size of the material through shearing, tearing and extrusion. This shredder is widely used Applied to the shredding of waste plastics, waste rubber, wood and other bulky wastes. The double-shaft shredder uses the friction force of the roller surface to bite the material into the crushing area, shear, squeeze and tear the material, and the material is squeezed or split to achieve the purpose of crushing. In order to increase the splitting effect, teeth or grooves are often made on the roll surface. [0003] Such as Figure 1-2 Shown is a schematic diagram of the cutter rolls of the biaxial shredder in the prior art. The knife ro...

AI Technical Summary

Problems solved by technology

[0004] When this kind of knife roller is used to crush tires, since the claws on the blade mainly play the role of carrying material, the number of claws is small, the shearing effect is not good, and the broken tire pieces are relatively long, even after passing through the disc sorting machine. Screening, the tire pieces that are screened out will still have a large proportion of longer lengths

Because the length of the tire piece is too long, if it is not effectively controlled within a certain size range, it will cause a relatively large load on the subsequent steel wire separator or roller machine, thereby reducing the output of subsequent equipment

In addition, during the process, the knife roller will be constantly impacted and worn, and the connection between the blade and the knife shaft is prone to instability, which will affect the crushing effect; and the integrated design of the blade is not conducive to the maintenance of the equipment
