Plastic recycling crusher

Abstract

The invention discloses a plastic recycling crusher, and relates to the technical field of plastic machines. The plastic recycling crusher comprises a rack, a feeding hopper arranged at the upper portion of the rack, a lower crushing wheel arranged on the rack, and an upper crushing wheel arranged above the lower crushing wheel. The center of the upper crushing wheel is fixedly connected with a rotating shaft, and the rotating shaft is rotationally connected with the lower crushing wheel and the rack. The lower crushing wheel is fixedly or rotationally connected with the rack. The lower surface of the upper crushing wheel and the upper surface of the lower crushing wheel are grinding faces matched with each other. The feeding hopper is located above the upper crushing wheel. The upper crushing wheel is internally further provided with a plurality of feeding ports communicating with the feeding hopper and the grinding faces. Material collecting grooves are formed in the periphery of the lower crushing wheel. The rack is further provided with a drive motor and a gear case. The drive motor is connected with the rotating shaft through the gear case. According to the plastic recycling crusher, the characteristic of tenacity of plastic particles is avoided, the plastic particles are crushed through friction force, and the crushing effect and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of plastic machinery, in particular to a plastic recycling pulverizer. Background technique [0002] At present, the granulation production line mainly includes a mixing device, an extrusion granulation device, a cooling device and a granulation device. The granulation device extrudes multiple strips of plastic, passes these strips of plastic through the cooling device, cools and cleans them, and finally cuts them into pellets by the granulation device, and finally repacks them. [0003] In actual production, some unqualified products need to be crushed in a plastic grinder first, and then the above process is repeated to save costs. In the prior art, the plastic pulverizer utilizes two pulverizing rollers arranged alternately to pulverize the plastic. When crushing plastic particles, the plastic particles are more subject to extrusion force. Since the plastic itself has good toughness, after the crushing ...

AI Technical Summary

Problems solved by technology

When crushing plastic particles, the plastic particles are more subject to extrusion force. Since the plastic itself has good toughness, after the crushing roller squeezes it, it is often only deformed into a flat shape. In order to make the plastic particles meet the required Therefore, the existing plastic pulverizers not only have poor crushing effect, but also have low crushing efficiency.
