Double-screw extruder

Abstract

The invention belongs to the technical field of extruders, and particularly relates to a double-screw extruder which comprises an operating floor, a fan, a control panel, a first motor, a second motor, a threaded rod, a feeding pipe, a spherical pipe, a stirring plate, a first shaft rod, a feeding bin, a mixing drum, an exhaust pipe, a spray head, a receiving funnel, a third motor, a second shaftrod, a gear ring, a gear, a screen drum, a cooling tank, a mesh enclosure, a stirring blade, a rotary rod, a discharge pipe, a collecting box and an installation rack. According to the double-screw extruder, through the interaction of the spherical pipe, the feeding bin, the shaft rods and the stirring plate, plastic raw materials and auxiliary materials can be mixed, and the plastic raw materialsare mixed uniformly and sufficiently through the threaded rod, so that the quality of the plastic raw materials is improved, and meanwhile, the processing efficiency is further improved; and the processed plastic raw materials can be cooled, so that the cooling speed of the plastic raw materials is greatly accelerated, and the cooling time is shortened.

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 hopper to feed plastics and auxiliary materials and then mix and extrude them through the screw. In this way, it is easy to make the mixing of plastic raw materials not uniform enough, thereby reducing the plastic waste. T...

Problems solved by technology

[0003] Most of the existing twin-screw extruders use a hopper to feed plastics and auxiliary materials and then mix and extrude them through the screw. In this way, it is easy to make the mixing of plastic raw materials not uniform enough, thereby reducing the plastic waste. 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
