Broken plastic regeneration plasticizer

Abstract

The invention relates to the field of waste plastic recycle, and aims at providing a broken plastic regeneration plasticizer. The broken plastic regeneration plasticizer comprises a machine base, a cutting-mixing pre-plasticizing device, a main plasticizing device and a vacuum suction filter device, wherein the cutting-mixing pre-plasticizing device is provided with a feeding hopper and a discharging port; the main plasticizing device comprises a cylinder which is provided with a cylinder heating device and connected with the machine base, a middle rod, two ends of which are connected with the cylinder, a plurality of main spiral push rods, two ends of which are pivoted with the cylinder, and a push rod driving device; an auxiliary spiral push rod is arranged in the interspace outside every two adjacent main spiral push rods; two ends of the auxiliary spiral push rods are pivoted with the cylinder; and the cylinder is provided with a plasticizing inlet which is arranged at the rear part of the side of the cylinder and communicated with the discharging port, a plasticizing outlet which is located at the front end of the cylinder, and an exhaust vent which is communicated with the inlet of the vacuum suction filter device.

Description

technical field [0001] The invention relates to the field of recycling waste plastics, in particular to a recycling plasticizing machine for crushed plastics. Background technique [0002] After the waste plastics are crushed, cleaned and dried, they can be made into recycled plastic raw materials by heating and plasticizing; the utility model of Chinese patent application No. CN201220184561.8 discloses a pulverizing and plasticizing machine, which includes The screw in the barrel is a variable-pitch screw, and the pitch of the screw changes from large to small in the direction from the inlet of the barrel to the outlet of the 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 plasticizing process It is a problem to be so...

AI Technical Summary

Problems solved by technology

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