[0002] Plastic pipes are generally made of synthetic resin, that is, polyester, as raw materials, and stabilizers, lubricants, plasticizers, etc. are added. They are processed by extrusion in a pipe-making machine by the method of "plasticizing". They are mainly used as pipes for the tap water supply system of building construction, gas, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and conduits for wire installation. Plastic pipes are divided into two categories: thermoplastic plastic pipes and thermosetting plastic pipes. Thermoplastic ones include TPR pipes, polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, etc., and thermosetting ones include phenolic plastic pipes, etc.

[0004] After a large number of searches, it is found that the Chinese patent publication number: CN217169647U discloses an energy-saving plastic pipe extrusion equipment. The utility model injects the granulated raw materials into the interior of the extrusion box through a feed hopper, and then starts the driving motor to drive the rotating shaft to rotate. When the raw materials pass through the heating cylinder, they are heated to melt the raw materials. The rotating shaft drives the extrusion screw to rotate and extrude the raw materials towards the extrusion die. However, when actually producing plastic pipes, different specifications of plastic pipes need to be produced according to production requirements.
