Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe forming machines, in particular to a PE pipe forming machine with a cooling mechanism. Background Art

[0002] PE pipe is a pipe made of polyethylene material, which is widely used in many fields, such as building water supply, building drainage, etc. When preparing PE pipe, it is usually completed on the corresponding PE pipe forming machine. PE pipe forming machine is a kind of equipment for producing PE pipe, which is mainly composed of machine head, mold, traction machine, cutting machine and other parts. PE pipe forming machines mostly use the molten material to extrude outward through the corresponding mold to complete the PE pipe preparation operation.

[0003] Since the PE tube forming machine completes the preparation operation by extruding the molten raw materials outward, at this time, the newly prepared PE tube itself still has a relatively high temperature. The hot PE tube usually needs to be cooled. If it is not cooled in time, the hardness of the PE tube is low and it will be deformed under pressure. At this time, the traditional method is generally to directly use the prepared PE tube to expose it to the air to complete the cooling and heat dissipation operation. Some PE tube forming machines use fans to blow air for cooling and cooling. It is difficult to achieve a good cooling effect when directly exposed to the outside. The fan blowing is also affected by the external temperature. If the external temperature itself is high, it will also cause a poor cooling effect, which is not conducive to timely cooling and cooling the newly prepared PE tube, causing inconvenience to the user. In view of this, we propose a PE tube forming machine with a cooling mechanism. Utility Model Content

[0028] In this embodiment, an air outlet pipe 271 is fixedly installed on the top cylinder of the rear sleeve 27, and an external delivery pipe 272 is fixedly installed on the top of the air outlet pipe 271 to facilitate the discharge of the hot air after heat exchange; the end of the external delivery pipe 272 is fixedly installed on an external heat exchange device to recycle the heat in the discharged hot air.
