Electromagnetic heating pp pe pvc pet wasted recycling plastic pellets granulator machine

The main machine of plastic pellets granulator machine, which consists of extrusion system, drive system and heating and cooling system. We should vigorously develop renewable resources and turn waste into treasure.

Extrusion system

Including hopper, die, plastic through the extrusion system and plasticized into a uniform melt, and in the process of the establishment of pressure, by the screw continuous extrusion die. he function of the transmission system is to drive the screw, which supplies the torque and speed needed by the screw in the extrusion process. It is usually composed of motor, reducer and bearing.

1. Screw is the most important part of the extruder. It is directly related to the application scope and productivity of the extruder. It is made of high-strength corrosion-resistant alloy steel.

2. The barrel is a metal cylinder, which is generally made of alloy steel or composite steel pipes lined with alloy steel with high heat resistance, high compressive strength, strong wear resistance and corrosion resistance. The barrel cooperates with the screw to realize crushing, softening, melting, plasticizing, exhausting and compacting of the plastics, and continuously and evenly conveying the adhesive to the molding system. Generally, the length of the barrel is 15-30 times its diameter, so that the plastic can be fully heated and fully plasticized.

3. The bottom of the hopper is equipped with a cutting device to adjust and cut off the flow of material. The side of the hopper is equipped with a viewing hole and a calibrating and measuring device.

4. the die is made of alloy steel inner sleeve and carbon steel coat, and the molding die is installed inside the machine head. The function of the die is to transform the rotating plastic melt into a parallel linear motion, evenly and smoothly into the mold sleeve, and give the necessary molding pressure to the plastic. Plastic is plasticized and compacted in the barrel, and flows into the die through the neck of the head and neck of the machine through a certain runner through the porous filter plate. The core sleeve is properly matched to form an annular cavity with decreasing cross-section, which makes the plastic melt form a continuous and compact tubular coating around the core line. In order to ensure the reasonable flow channel of plastic in the die and eliminate the dead angle of the accumulated plastic, a shunt sleeve is often installed. In order to eliminate the pressure fluctuation during the plastic extrusion, a pressure equalizing ring is also installed. The machine head is also equipped with a device for die correction and adjustment, which is convenient for adjusting and correcting the concentricity of the die core and the die sleeve.

Drive system

The function of the drive system is to drive the screw, which supplies the torque and speed needed by the screw in the extrusion process. It is usually composed of motor, reducer and bearing.
