Efficient shredder for two-end interactive crushing

Abstract

An efficient shredder for two-end interactive crushing comprises a body, above which a feed inlet is arranged. A material pushing box capable of reciprocating motion is arranged below the feed inlet. Two ends of the body are respectively provided with left and right cutting mechanisms. The cutting mechanism comprises a cutter shaft, a moving cutter installed on the cutter shaft, and an upper fixed cutter and a lower fixed cutter which are installed inside the body. The upper fixed cutter, the lower fixed cutter and the moving cutter are arranged in a staggered manner. When the cutter shaft rotates, a cutting face is formed between the moving cutter and the upper fixed cutter and the lower fixed cutter. The material pushing box is positioned between the two cutting mechanisms. When the material pushing box is reciprocating, a material can be respectively pushed towards the cutting face of the corresponding cutting mechanism. During crushing process of the material, the material can be pushed to the cutting face through forward and back moving of the material pushing box. Thus, the material pushing box has no noncutting stroke, continuous cutting crushing is realized, and work efficiency of the shredder is greatly enhanced. The shredder also has advantages of simple structure, low cost and convenience in use, and has a good market prospect.

Description

technical field [0001] The invention relates to a shredder capable of crushing materials, in particular to a high-efficiency shredder capable of crushing materials at both ends. Background technique [0002] The shredder is used to shred all kinds of solid or hollow materials such as plastics, rubber, tires, fibers, paper, wood, iron drums, waste electrical appliances, waste cables, industrial scraps, domestic garbage, etc. Compared with other shredders, its characteristics It is widely used because of the low speed of the cutter shaft, low noise and low energy consumption. For example, the leftovers of plastic or rubber are shredded and used as raw materials to melt and granulate, which are used to remake plastic bottles, tires or trash cans, etc. In the plastic recycling industry, shredders are usually used to shred waste large-diameter PE plastic pipes, bundled plastic films, large stacks of plastic sheets and machine head materials. [0003] The current single-shaft sh...

Problems solved by technology

When the push box is returning, even the cutter shaft is constantly rotating, but at this time the material does not have the driving force of the push box, so the crushing work cannot be carried out. The process of returning all the push boxes is completely a job Auxiliary process of the cycle, which wastes time and electricity
