Description

[0001] This invention relates to the field of plastic tube extrusion technology, specifically to an extruder capable of continuously winding plastic tubes. Background Technology

[0002] Plastic pipes are made primarily from synthetic resins, with the addition of stabilizers, lubricants, plasticizers, and other auxiliary materials. Due to their lightweight, corrosion resistance, attractive appearance, lack of unpleasant odor, ease of processing, and convenient construction, they are widely used in the construction engineering field. Plastic pipes are manufactured through an extrusion process, which typically requires the use of an extruder.

[0003] Currently, the production of existing plastic pipes is completed by multiple machines. This method requires loading and unloading in the middle stage, which saves time and labor, but increases the labor intensity of plastic pipe production and reduces work efficiency. Moreover, existing plastic pipes cannot achieve automatic winding function after extrusion. If winding is required, an external coiling machine is needed. At the same time, existing plastic pipes require more power to operate, so energy consumption and cost are relatively high. Summary of the Invention
