Crusher for waste plastics

Abstract

The invention relates to a crusher for waste plastics. The crusher comprises a rack and a crushing barrel, wherein the crushing barrel is fixed on the rack and is communicated with a feeding channel;the crushing barrel is internally and rotatably connected with a crushing mechanism; the feeding channel is connected with a pushing plate in a sliding way; a first piston cylinder is fixed on the rack; a first piston is connected in the first piston cylinder in a sliding way; a first wedge groove is formed in the pushing plate; a first wedge rod, inserted into the first wedge groove, is fixed onthe rack; a third spring is connected between the first wedge rod and the rack; a second wedge groove is formed in the first wedge rod; a second wedge rod, inserted into the second wedge groove, is fixed on the first piston; the first piston cylinder is communicated with an air inlet pipe; the rack is provided with an air inflating mechanism, and the air inflating mechanism is communicated with the air inlet pipe; the piston cylinder is also communicated with an air outlet pipe; an inclined plate, opposite to the pushing plate is fixed in the crushing barrel. Compared with the prior art, the crusher can be used for preliminarily crushing the waste plastics by means of the pushing plate and the inclined plate which are cooperatively used, so that the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of crushing equipment, in particular to a crusher for waste plastics. Background technique [0002] At present, most of the plastic recycling process requires the use of crushers, and the recycled plastics must be put into the crusher to be broken into small particles before further processing. [0003] A traditional crusher generally includes a crusher working room, a crushing hammer installed at the bottom of the crusher working room, a feeding port arranged on the upper part of the crusher working room, and a discharge screen located under the crusher knife. During the crushing process of traditional crushers, all the waste plastics that need to be crushed are generally put into the crusher. Since there are more plastics to be crushed, the load of the crushing hammer is relatively large, and the blocky plastics will be crushed in the crusher working room. Roll up and down, stay for a long time to completely crush,...

Problems solved by technology

During the crushing process of traditional crushers, all the waste plastics that need to be crushed are generally put into the crusher. Since there are more plastics to be crushed, the load of the crushing hammer is relatively large, and the blocky plastics will be crushed in the crusher working room. Roll up and down, stay for a long time to break completely, the crushing efficiency is low, seriously affecting the output
