Description

Technical Field

[0001] The utility model relates to the technical field of production and cutting of polyethylene outer protective pipes, in particular to a ring-shaped rotating cutting device for the production of polyethylene outer protective pipes. Background Art

[0002] At present, the production process of high-density polyethylene outer protective tube is to plasticize the raw materials and then enter the extruder. After flowing out of the extruder, it is connected to the traction pipe and directly led out. The existing extruders for the production of polyethylene outer protective tubes mostly use water spraying to cool down and cool down the outer protective tube during production, and the effect is single. The local cooling caused by water spraying affects the cooling and molding effect of the outer protective tube, and the water spray cooling causes a lot of water to adhere to the outer protective tube, which needs to be handled separately later. In addition, after the outer protective tube is cooled and formed, it is cut by saw blades in the past, which easily causes more burrs on the cut end of the outer protective tube. In the later stage, it needs to be polished to remove the burrs, which increases the processing steps. And because of the pressure cutting during the cutting process, the cut end is deformed, which is not easy to correct during the later pipe threading, and the work intensity is increased.

[0003] As disclosed in Chinese patent CN113997542A, a polyethylene outer protective tube production process for heat-insulating pipes is proposed. The polyethylene raw materials are heated and mixed, and then extruded into an outer protective tube by an extrusion mechanism through a mold; the extruded outer protective tube is cooled by a cooling and shaping mechanism, and the cooling and shaping mechanism performs air cooling and water cooling on the outer protective tube; after the outer protective tube after cooling and shaping is extended to a set length, it is cut by a cutting device for circular rotation, and the cutting device adopts a progressive cutting method, and the incision is neat; after the cooling and shaping and rotary cutting steps are operated, the processing of the outer protective tube is completed. It can be seen from the above description that after the outer protective tube enters the cooling and shaping process; the outer protective tube after shaping adopts a progressive rotary cutting method, which effectively prevents the problems of large number of port burrs and cutting deformation generated during the cutting process.

[0004] However, in the prior art, during the production and cutting process of the polyethylene outer protective pipe, since the lengths of the pipes are different during the production process of the polyethylene outer protective pipe, when the pipes are cut during the production process, the distance between the pipe clamping and fixing structure and the cutting structure needs to be adjusted according to the length and size of the pipe, so that it can be clamped and cut more flexibly.
