Film crushing plasticator

Abstract

The invention relates to the field of recycling of waste plastics and provides a film crushing plasticator. The film crushing plasticator comprises a machine frame and further comprises a crushing, stirring and preplasticizing device, a plasticizing and toughening device and an exhaust air filter device, wherein the crushing, stirring and preplasticizing device is provided with a feeding hopper and a discharging outlet; the plasticizing and toughening device comprises a barrel provided with a barrel heating device and connected with the machine frame, a middle spiral push rod connected with the barrel in a pivoted mode, a plurality of outer spiral push rods distributed in the circumferential direction of the middle spiral push rod and connected with the barrel in a pivoted mode, and a spiral push rod drive device; and the barrel is provided with a plasticizing inlet located at the rear portion of the side body of the barrel and communicating with the discharging outlet, a plasticizing outlet located in the front end of the barrel, and an exhaust hole communicating with an inlet of the exhaust air filter device. The film crushing plasticator is good in effect of mixing, extruding and rubbing of plasticized raw materials in the plasticizing process, gas is exhausted easily, and prepared plastic renewable raw materials are good in toughness.

Description

Technical field [0001] The invention relates to the field of recycling and utilization of waste plastics, in particular to a crushing film plasticizer. Background technique [0002] After the waste plastic film is crushed, cleaned, and dried, it can be recycled into plastic recycled materials by heating and plasticizing; the utility model of Chinese Patent Application No. CN201220184561.8 discloses a crushing and plasticizing machine, which includes a melting device The screw in the barrel is a variable-pitch screw, and the pitch of the screw varies from large to small in the direction from the inlet of the adjacent barrel to the outlet of the barrel. Traditional plasticizers have poor mixing, squeezing and kneading effects on plasticizing raw materials during the plasticizing process, and the gas is not easy to discharge, resulting in the insufficient toughness of the plastic recycled raw materials. Therefore, design a plasticizing process The plasticizing raw material mixing, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of the existing plasticizing machines in the plasticizing process, such as poor mixing, extruding and kneading effects on the plasticized raw materials and difficult gas discharge, resulting in poor toughness of the produced plastic recycled raw materials, and to provide a A broken film plasticizing machine with good mixing, extrusion and kneading effects on the plasticized raw materials during the plasticizing process, and the gas is easy to discharge, and the plastic recycled raw materials made have good toughness
