Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipe production clamping fixtures, in particular to a PVC pipe production discharging traction device. Background Art

[0002] During the PVC pipe production process, an extruded pipe is formed by hot extrusion injection molding. The extruded pipe is used as a traction pipe through a finished PVC pipe of the same model located downstream of the extrusion die. The traction equipment drives the extruded pipe to move downstream through the traction pipe to complete the transportation.

[0003] There are many ways to connect PVC extrusion tubes and traction tubes, but after our company's research and investigation, there is no unified method. Some factories directly stick the newly extruded sticky extrusion tube to the end of the traction tube. This method requires the end of the traction tube to be heated and preheated first, and then the newly extruded PVC extrusion tube is wrapped and glued to the end of the traction tube. After gluing, the hot PVC tube needs to be cooled down to cool and fix it; some factories use ropes to tie the extrusion tube and the traction tube. This method is more troublesome. It is necessary to ensure that the rope tied on the outside of the traction tube is relatively thin so as not to cause the overall size of the traction tube to be too large, and it is also necessary to cool the extrusion tube to prevent it from being torn off by the rope before it is formed. Since there are no special tools, whether it is traction by gluing or traction by rope, because gluing and tying are new operations, more operating steps need to be repeated each time traction, which cannot improve efficiency and save time, and needs to be improved.
