SJ-50 single screw extruder Dual PVC pipe line with haul off and cutter

What is a single screw extruder?
The single screw pipe extruder is a plastic processing equipment, which is mainly used to produce plastic pipes of various specifications. Its core component is a rotating screw, which is located in a heated barrel. Under the rotation of the screw, the plastic raw material is fed into the barrel and gradually heated to a molten state. Then, the molten plastic is extruded by high pressure, and after being molded by a mold, the pipe of the desired shape is finally obtained.

The main components of the single screw pipe production line include the raw material conveying system, the melt extrusion system, the mold molding system, the cooling and shaping system, the traction cutting system and the control system.
A1: The raw material delivery system is responsible for delivering the plastic raw materials to the extruder, the melt extrusion system heats the raw materials, melts them and extrudes them, A2: The mold forming system makes the molten plastic form the cross-sectional shape of the pipe
A3: The cooling and shaping system keeps the pipe in shape during the cooling process
A3: The traction and cutting system pulls out the cooled pipe and cuts it, and the control system isresponsible for monitoring the operating status of the entire production line and adjusting the process parameters as needed.

In terms of working principle, the single-screw pipe equipment uses the rotary motion of the screw to drive the material to move in the sleeve. The screw is driven to rotate by a motor or other power equipment, and the material continues to move forward under the push of the screw. Due to the irregularity of the screw arrangement, the material is mixed and extruded during the movement, thereby achieving the desired processing effect.
