Shuliy plastic pellet machine

by allen guo Food Processing Machinery
The main machine of the plastic pellet machine structure is an extruder, which is composed of an extrusion system, a transmission system and a heating and cooling system.
Recommended Features
  • Extrusion system The extrusion system consists of a screw, barrel, hopper, head, and die. Plastic is plasticized into a uniform melt through the extrusion system.
  • Under the working pressure established in this process, Extruder head.
  • (1) Screw: It is the most important part of the extruder. It is related to the use scope and productivity of the extruder. It is made of high-strength and corrosion-resistant alloy steel.
  • (2) Barrel: It is a metal material barrel, usually made of alloy steel or composite steel pipe lined with alloy steel with high temperature resistance, high compressive strength, strong wear resistanc
  • The barrel cooperates with the screw to achieve the crushing, softening, melting, plasticizing, venting and compaction of the plastic, and to continuously and uniformly convey the rubber to the formi

Review on Shuliy plastic pellet machine

Generally, the total length of the barrel is 15 to 30 times its diameter. The principle is to make plastics obtain various aspects of heating and plasticization. Introduction to the structure of the plastic pellet machine (3) Hopper: The bottom of the hopper is equipped with a cutting device to adjust and cut off the material flow. The side of the hopper is equipped with a sight hole and a calibration metering device. (4) Machine head and mold: The machine head is composed of an alloy steel inner sleeve and a carbon structural steel jacket, and a forming die is installed in the machine head. The function of the machine head is to transform the plastic melt that automatically rotates into parallel and linear motion at a uniform speed, and it is introduced into the top block symmetrically and stably, and the plastic is given the necessary forming working pressure. The plastic is plasticized and compacted in the barrel, and passes through the porous filter plate through a certain flow channel through the neck of the head and flows into the head forming mold. The core mold sleeve is properly matched to form a circular gap with a decreasing cross-section so that the plastic melt is A continuous and dense tubular coating is formed around the core wire. To ensure that the plastic flow path in the machine head is effective and clear the dead corner of the accumulated plastic, a shunt sleeve is often installed. To clear the fluctuation of the working pressure when the plastic is squeezed out, there is also a lightning receptor. The head is also equipped with a device for adjusting and correcting the concentricity of the mold core and the top block.
