Description

Grinder is used in production of modified polyethylene resin Technical Field The utility model relates to the technical field of production of polyethylene modified resin, in particular to a pulverizer for producing polyethylene modified resin. Background Polyethylene modified vinyl resin (such as EVA, PVC, etc.) is widely applied to the fields of packaging, shoe materials, etc. because of excellent flexibility and viscoelasticity, and is crushed into particles by mechanical crushing in the recovery or processing process, so that the subsequent processing or storage and transportation are facilitated, however, the resin is softened after being heated by shearing friction during crushing, the melting phase transition temperature is low, and the resin particles are easy to adhere to the surface of a cutter blade; In the traditional pulverizer, the problem of cutter surface adhesion is solved by plating a Teflon or ceramic coating on the surface of a cutter blade and adopting a mode of cooling by blowing cold air to the cutter surface, but the coating or cooling is only effective for a short period and can not be used for continuous production for eight hours or even longer. Disclosure of utility model The utility model aims to provide a pulverizer for producing a polyethylene resin, which solves the problem that the temperature of a cutting edge is increased due to contact friction between a blade and the polyethylene resin in the pulverizing process of the pulverizer, so that polyethylene resin particles are adsorbed, and the overall pulverizing efficiency is affected. The pulverizer for producing the polyethylene resin comprises a machine body, wherein a pulverizing box is fixedly arranged at the top of the machine body, a feeding pipe is fixedly arranged at the top of the right side of the pulverizing box, fans are symmetrically arranged at the top of the pulverizing box, and a plurality of discharge ports are formed in the right side of the machine body; The inner chamber middle part demountable installation of smashing the case has the center pin, and the surface fixed mounting of center pin has a plurality of blades, and the cutting edge has been seted up to one side symmetry of blade, and one side middle part of blade is equipped with the pivot, and the surface of pivot is equipped with the eccentric wheel, and the ring channel has been seted up to the opposite side of eccentric wheel, and the inner chamber symmetry of ring channel is equipped with the slider, and the connecting rod is installed through joint bearing rotation to the opposite side of slider, and the other end of connecting rod has the extension rod through articulating, and the other end of extension rod is connected with the scraper through the articulated shaft, and one side symmetry of blade is equipped with the stopper, and the bar slot has been seted up on the surface of stopper, and the spacing groove has been seted up to the inner chamber of stopper.
