Technical Field

[0001] The utility model belongs to the technical field of polyethylene pipe production, and in particular relates to automatic extrusion production equipment for ultra-high molecular weight polyethylene pipes. Background Art

[0002] Ultra-high molecular weight polyethylene raw materials and auxiliary materials are mixed according to the formula by the automatic weighing and mixing system and then transported to the finished product silo. The finished raw materials are transported to the extruder hopper by the automatic feeding system. The finished materials are shaped by high-temperature and ultra-high-pressure extrusion. After the pipes are automatically sawed, they are pushed to the pipe conveyor rack. The finished pipes are transported to the pipe identification conveyor by the automatic pipe conveyor and sent to the corresponding pipe yards.

[0025] As mentioned above, when using the cooling box 1, extrusion mechanism, support member and rotating mechanism provided by the utility model, when the extrusion mechanism extrude the extrudate, the extrudate is supported by the support member, and the rotating mechanism is started to drive the support member to rotate, thereby bringing the extrudate on the support member to the storage space where the coolant is stored. At this time, the extrusion mechanism extrude the extrudate onto the support member again, so that the support member can cool the extrudate on the support member while supporting the extrudate.

[0026] Further, in order to support the continuously extruded extrudate, reference is made to Figure 2-3 As shown, the support member includes a rotatable rotating shaft 4, and a plurality of placement grooves 9 are distributed in a ring array on the outer wall of the rotating shaft 4.
