Crushing structure of PE particle crushing machine

Abstract

The invention provides a crushing structure of a PE particle crushing machine. The crushing structure structurally mainly comprises a fixed knife pedestal, a fixed hole position, a fixed knife, a moving knife rest, a moving knife, a rotating shaft and a diaphragm, wherein the moving knife is welded on the moving knife rest, the fixed knife is fixedly connected on the fixed knife pedestal through lock screws, according to selection for different positions of the positioning hole, a gap between the fixed knife and the moving knife fits a to-be-crushed material in size, the rotating shaft is arranged at the center of the fixed knife pedestal through a bearing, a gap is reserved between the moving knife rest and the fixed knife pedestal, and the diaphragm is welded on the bottom of the moving knife rest. The crushing structure of the PE particle crushing machine can crush various waste plastics, is energy-saving and environmentally friendly, is simple in structure, and good in crushing effect, and thus the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a broken material structure of a PE particle pulverizer. Background technique [0002] At present, the scope of application of plastic products is becoming more and more extensive, and plastic waste is not perishable and accumulates over time, which will seriously affect the ecological environment of the earth. Therefore, people thought of recycling and reusing plastic waste. The key step in the recycling of waste plastics is to crush them into small pieces suitable for reprocessing. Therefore, various types of waste plastic shredders have emerged. The existing plastic shredders generally use a drum milling cutter to rotate the plastic to cut and shred. This type of equipment has large volume, complex structure, high equipment cost, low production efficiency, and unsatisfactory crushing effect. Contents of the invention [0003] The problem to be sol...
