Plastic crushing machine capable of discharging impurities

Abstract

The invention relates to a plastic crushing machine capable of discharging impurities. The crushing machine comprises a supporting frame and a sound insulation cotton; a crushing box is fixed to the upper end of the supporting frame, a second feeding opening is formed in the right side of the upper end of the crushing box, a control box is arranged on the left side of the crushing box, a hydraulicpump is arranged on the upper end inside the control box, six crushing knives are arranged in the crushing box, plastic crushing treatment is more sufficient, directions of knife edges between everytwo adjacent crushing knives are different, during rotation, the plastic stirring directions are different, the plastic not achieving the crushing effect flows up and down in the crushing box in a reciprocated manner, the plastic can make repeated contact with the breaking knives to be crushed, the plastic can be subject to repeated crushing treatment, the plastic crushing is more uniform, the time needed by crushing is reduced, the crushing efficiency of the crushing machine is improved, the six crushing knives are connected with the same first motor through a belt, and the manufacturing costof the crushing machine is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic crushers, in particular to a plastic crusher capable of removing impurities. Background technique [0002] The plastic crusher is mainly used to crush various plastic plastics and rubber, such as plastic profiles, pipes, rods, silk threads, films, and waste rubber products. The pellets obtained after being crushed by the crusher can be directly used for extruders or injection molding. , and can also be recycled through basic granulation. In the actual production process, the plastic crusher often uses a motor to drive the moving knife to rotate at a high speed. The plastic crushing and shearing cut caused by the gap formed by the relative movement between the fixed knife and the fixed knife will crush the large pieces of plastic, and the crushed plastic will be filtered and output through the screen, so that the particle size of the filtered plastic particles meets the actual needs. In the existi...

Problems solved by technology

[0003] The purpose of the present invention is to provide a plastic crusher capable of removing impurities, so as to solve the problem that the existing plastic production crusher proposed in the above background technology needs to separate impurities from the plastic before crushing the plastic, which requires a certain amount of labor. When feeding, due to too much plastic, the feeding speed is too fast, resulting in more plastic stuck in the feeding port, which affects the crushing efficiency, and the internal crushing tool is single, and the plastic needs to be repeatedly stirred and crushed each time, which is greatly improved. The crushing efficiency is reduced, the discharge method is complicated, and the crushed plastic cannot be discharged directly from the crushing box
