[0002] The pipe extruder belongs to one type of extruders. The equipment used for the pipe extruder is a screw extruder. Here, the screw extruder can be roughly classified into a single-screw extruder and a multi-screw extruder according to the number of screws. The pipe extruder usually puts plastic particle raw materials and water into the machine body through a hopper. The screw rotates driven by a motor, so that the materials are continuously conveyed into the barrel. The barrel heats the materials by electric heating to melt them, and finally extrudes and forms from the die orifice.
[0003] In pipe production, the raw materials are naturally formed by extrusion inside the shaping die cavity. The internal space of the shaping die cavity is generally fixed, and the size of the internal space is the size of the formed pipe. Therefore, when producing pipes with different diameters or wall thicknesses, different shaping dies need to be used. For traditional extrusion equipment, the shapes and sizes of the produced pipes are single, and it is not convenient to replace the shaping die cavity to produce different pipes.
