crushing plastic plasticizing machine

Abstract

The invention relates to the field of waste plastic recycling, and aims at providing a broken plastic plasticator. The broken plastic plasticator comprises a machine base, a cutting-up and stirring preplasticizing device, a main plasticizing device and an air exhausting filtering device, wherein the cutting-up and stirring preplasticizing device is provided with a feeding hopper and a discharging opening; the main plasticizing device comprises a barrel which is provided with a barrel heating device and connected with the machine base, a middle rod with the two ends connected with the barrel, a plurality of main spiral push rods in pivot joint with the barrel and a push rod driving device; an auxiliary spiral push rod is arranged in a gap of the outer sides of every two adjacent main spiral push rods; the two ends of each auxiliary spiral push rod are in pivot joint with the barrel; the barrel is provided with a plasticizing inlet which is formed in the rear portion of the side body of the barrel and is communicated with the discharging opening, a plasticizing outlet formed in the front end of the barrel and an air exhausting opening communicated with an inlet of the air exhausting filtering device. In the plasticizing process of the broken plastic plasticator, the mixing, extruding and rubbing effect on plasticizing raw materials is good, gas can be easily exhausted out, and toughness of prepared plastic regeneration raw materials is good.

Description

technical field

[0001] The invention relates to the field of recycling waste plastics, in particular to a plasticizing machine for broken 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 an urgent problem to be solve...
