Waste plastic crushing device

Abstract

The invention provides a waste plastic crushing device. The waste plastic crushing device comprises a compressing chamber, a heating chamber, a crushing chamber and a discharging chamber which are connected sequentially, wherein a feed port is formed in the top of the compressing chamber; a briquette which can reciprocate towards the opposite side is arranged on one side in the compressing chamber; a plurality of pressing rollers are arranged on the upper and lower parts in the heating chamber respectively; serrated knifes are distributed on each pressing roller; the crushing chamber is composed of a transverse crushing chamber and a vertical crushing chamber; one side of the transverse crushing chamber is communicated with the heating chamber; and the bottom part of the transverse crushing chamber is communicated with the vertical crushing chamber; due to the adoption of the waste plastic crushing device, the problems that the crushing is incomplete, the noise is high, the wearing of a tool bit is serious and splashing materials are likely to cause a safety hidden in a crushing process of a traditional plastic crushing device are solved; the waste plastics are compressed, heated, crushed and degraded, the degrading speed of the waste plastics is significantly improved, on the premise that the complete crushing is guaranteed, the working strength of the tool bit is lowered, the working efficiency is improved, and the crushing cost is reduced.

Description

technical field [0001] The invention relates to the field of plastic processing equipment, in particular to a waste plastic crushing device. 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. A traditional crusher generally includes a crusher working room, a crushing motor knife installed at the bottom of the crusher working room, a fixed knife set opposite to the crusher machine knife, a feeding port set on the upper part of the crusher working room, and a crusher located under the crusher knife. The discharge mesh plate. During the crushing process of traditional crushers, blocky plastics will roll up and down in the crusher working chamber, staying for a long time, and cannot be broken into small particles quickly. The crushing efficiency is low, which seriously affects the output. At the same time,...

Problems solved by technology

During the crushing process of traditional crushers, blocky plastics will roll up and down in the crusher working chamber, staying for a long time, and cannot be broken into small particles quickly. The crushing efficiency is low, which seriously affects the output. At the same time, blocky plastics are crushing The working room of the crusher rolls up and down and hits the inner wall of the working room of the crusher, which produces a lot of noise and seriously affects the work efficiency of workers.
