HDPE pipe has a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance, corrosion resistance, etc. In the water supply and drainage pipeline system, plastic pipe gradually replaces cast iron pipe and galvanized steel pipe and other traditional pipe materials and becomes the mainstream pipe material. Compared with traditional pipe materials, plastic pipe has the advantages of light weight, corrosion resistance, small water flow resistance, energy saving, simple and rapid installation, low cost and other obvious advantages, and is loved by the pipeline engineering field. After the extrusion of HDPE pipe, cutting processing is needed, and guiding equipment is needed for conveying and guiding the pipe in this process.

At the same time, the levelness of the end cutting is poor during the shaking process. When the pipe is conveyed, it will produce violent jolt, the pipe will produce offset in the center position, affect the normal production of the pipe, and because the HDPE hollow wall is in a high temperature state during production, it will also cause the pipe to be prone to deformation, thereby affecting the production quality of the pipe.

The external thread on the adjusting screw 7 is used to cooperate with the threaded hole. A through hole is provided on the first connecting rod 11, and a protrusion is provided at the end of the adjusting screw 7 to match and limit the movement of the through hole, so that the adjusting screw 7 and the first connecting rod 11 can be rotatably connected.

[0030] The method of using this utility model is as follows:

[0031] 1. Place the pipe into the circular through hole in the middle of the fixed bracket 3;

[0032] 2. Control the adjusting handwheels 6 on both sides of the pipeline, and control the adjusting screw 7 to be screwed into the position of the second connecting rod 12, thereby changing the position of the first connecting rod 11, and thus controlling the distance between the two pressing rollers 5, so as to achieve appropriate pressing of the pipeline by the pressing rollers 5.

[0033] Furthermore, the fixed base 2 is circular, and its upper surface has four mounting holes for connecting to the outer wall of the processing equipment (not shown). The fixed base 2 has a circular through hole in the middle, the diameter of which matches the outer diameter of the pipe.
