The working principle of the extruder screw:   

1) Suction process: The screw type intake side suction port must be designed so that the compression chamber can fully inhale, while the double alloy screw compressor has no intake and exhaust valve groups, and the intake air is only adjusted by one. The opening and closing adjustment of the valve, when the rotor rotates, the space of the groove of the main and auxiliary rotors is the largest when the air is turned to the opening of the inlet end wall, and the space of the groove of the rotor is communicated with the free air of the air inlet. When the exhaust gas is exhausted, the air in the groove is completely exhausted. When the exhaust is completed, the tooth groove is in a vacuum state. When the air is turned to the air inlet, the outside air is sucked and flows into the groove of the main and auxiliary rotors in the axial direction. When the air fills the entire tooth groove, the air intake side end surface of the rotor is turned away from the air inlet of the casing, and the air between the tooth grooves is closed.   

2) Closing and conveying process: When the main and auxiliary rotors are at the end of inhalation, the main and auxiliary rotor tooth peaks will be closed with the casing. At this time, the air is closed in the tooth groove and no longer flows out, that is, [closed process]. The two rotors continue to rotate, and the tooth peaks coincide with the groove at the suction end, and the mating surface gradually moves toward the exhaust end.   

3) Compression and fuel injection process: During the conveying process, the meshing surface gradually moves toward the exhaust end, that is, the gap between the meshing surface and the exhaust port gradually decreases, and the gas in the groove is gradually compressed and the pressure is increased. This is the [compression process]. At the same time, the lubricating oil is also injected into the compression chamber and mixed with the chamber gas due to the pressure difference.   

4) Exhaust process: When the meshing end face of the rotor is turned into communication with the exhaust of the casing, (the pressure of the compressed gas is the highest), the compressed gas begins to discharge until the meshing surface of the tooth peak and the groove moves to the exhaust. End face, at this time, the space between the two rotor meshing surfaces and the casing exhaust port is zero, that is, the completion (exhaust process), at the same time, the length of the groove between the rotor meshing surface and the casing air inlet is the highest. Long, the inhalation process is going on.

Features

The single-screw extruder is mainly used for extruding soft plastics such as soft and hard polyvinyl chloride and polyethylene. 

It can process a variety of plastic products, such as blown film, extruded tube, pressure plate, ribbon, etc., and can also be used for melt granulation. The plastic extruder has advanced design, high quality, good plasticization and low energy consumption. It adopts involute gear transmission, featuring low noise, stable operation, large bearing capacity and long service life.
