A twin-screw extruder

Abstract

The invention belongs to the technical field of extruders, and specifically relates to a twin-screw extruder, which includes a console, a fan, a control panel, a first motor, a second motor, a screw, a material guide pipe, a spherical pipe, a stirring plate, The first shaft, the feeding bin, the mixing cylinder, the exhaust pipe, the nozzle, the receiving funnel, the third motor, the second shaft, the gear ring, the gear, the screen cylinder, the cooling box, the net cover, the stirring blade, the rotating rod , discharge pipe and collection box, mounting frame. This kind of twin-screw extruder can better mix the plastic raw materials and auxiliary materials by setting the spherical tube, the feeding bin, the shaft rod and the stirring plate, so that the screw can mix the plastic raw materials more evenly and fully, thus The quality of plastic raw materials is improved, and the processing efficiency is also improved; the processed plastic can be better cooled, which greatly speeds up the cooling speed of plastic raw materials and shortens the cooling time.

Description

technical field [0001] The invention belongs to the technical field of extruders, in particular to a twin-screw extruder. Background technique [0002] The twin-screw plastic extruder is a high-quality and efficient plastic extrusion equipment. The plastic extruder has a reasonable structural design, a sturdy and durable structure, and is not easy to be damaged. The material rod of the machine adopts a heat treatment carbonization process, which is hard and not easy to wear, and has a long service life. It is three times that of ordinary rods. It adopts advanced lubrication test, which has little wear and tear. The large tile seat completely protects the bearings and is easy to operate and maintain. [0003] Most of the existing twin-screw extruders use a feeding bin to feed plastic raw materials and auxiliary materials and then mix and extrude them through the screw, which makes it easy to mix the plastic raw materials unevenly, thereby reducing the plastic The quality of ...

Problems solved by technology

[0003] Most of the existing twin-screw extruders use a feeding bin to feed plastic raw materials and auxiliary materials and then mix and extrude them through the screw, which makes it easy to mix the plastic raw materials unevenly, thereby reducing the plastic The quality of the raw material also reduces the work efficiency, and when the screw extrudes the plastic raw material, due to the friction between the screw and the plastic raw material, a large amount of heat will be generated, so that the plastic raw material has a certain temperature, and most of the existing It is the natural heat dissipation of plastic raw materials, so that the heat dissipation is relatively slow, which greatly prolongs the working time
