Low-noise impurity-removing type plastic pulverizer

Abstract

The invention discloses a low-noise impurity-removing type plastic pulverizer. The low-noise impurity-removing type plastic pulverizer comprises a pulverizing knife group (10), a feeding cylinder (30), a powder partition plate (40), a screen net (50), a discharging cylinder (60), a box body (70), a metal separator (100) and a motor; the pulverizing knife group (10), the feeding cylinder (30), the powder partition plate (40), the screen net (50) and the metal separator (100) are arranged in the box body (70); the discharging cylinder (60) is fixedly arranged below the box body (70); and the motor is arranged outside the box body (70). The low-noise impurity-removing type plastic pulverizer can separate metal particles and plastic particles, prolong the service life of the blade of the plastic pulverizer and reduce noise; meanwhile, the three-axis pulverizing knife group pulverizes the plastic, so that the pulverized particles are uniform and complete.

Description

technical field [0001] The invention relates to the field of plastic manufacturing, in particular to a low-noise and impurity-removing plastic pulverizer. Background technique [0002] Plastic pulverizers are widely used in the plastic manufacturing industry. The raw materials of existing plastic pulverizers are generally from recycled plastic waste, and there are many impurities. Non-metallic impurities can generally be removed clearly by liquid, and metal impurities are often mixed into plastic raw materials, which often block injection molding. The nozzle of the grinder will damage the blade of the grinder and scratch the cylinder of the machine, which is very harmful. At the same time, the plastic grinder in the prior art has only one set of crushing knives, which directly cuts and grinds the plastic, and the crushing is not sufficient. The blades are seriously damaged, and the blades need to be replaced frequently; meanwhile, in the prior art, there is only one feeding ...
