Crushed film regeneration plasticator

Abstract

The invention relates to the field of waste plastic recycling, and aims at providing a crushed film regeneration plasticator. The crushed film regeneration plasticator comprises a rack and further comprises a cutting and stirring pre-plasticizing device, a plasticizing toughening device and a vacuum air pumping and filtering device, and the cutting and stirring pre-plasticizing device is provided with a feeding hopper and a discharging port. The plasticizing toughening device comprises a cylinder, a middle spiral push rod, a plurality of outer spiral push rods and a spiral push rod drive device, wherein the cylinder is provided with a cylinder heating device and connected with the rack, the middle spiral push rod is in pivot joint with the cylinder, and the multiple outer spiral push rods are distributed along the circumference of the middle spiral push rod and are in pivot joint with the cylinder. The cylinder is provided with a plasticizing inlet located in the rear portion of the side body of the cylinder and communicating with the discharging port, a plasticizing outlet located in the front end of the cylinder, and an air pumping hole communicating with an inlet of the vacuum air pumping and filtering device. The crushed film regeneration plasticator has good mixing, extruding and kneading effects on plasticizing raw materials in the plasticizing process, air is easily exhausted, and manufactured plastic regeneration raw materials are good in tenacity.

Description

technical field [0001] The invention relates to the field of recycling waste plastics, in particular to a recycling plasticizing machine for shredded films. Background technique [0002] After the waste plastic film is crushed, cleaned and dried, it can be made into recycled plastic raw materials by heating and plasticizing; the utility model of Chinese patent application number CN201220184561.8 discloses a pulverizing and plasticizing machine, which includes a melting device The screw rod in the barrel is a variable-pitch screw, and the pitch of the screw changes from large to small in the direction from the feed port of the feed barrel to the discharge port of the feed barrel. The traditional plasticizing machine has the disadvantages of mixing, extruding and kneading the plasticized raw materials during the plasticizing process, and the gas is not easy to discharge, resulting in poor toughness of the plastic recycled raw materials. Therefore, it is necessary to design a p...
