[0002] PE pipe cooling bed is a kind of equipment used in the production process of PE (polyethylene) pipes. It is mainly used to cool and shape the high-temperature PE pipes that have just been extruded. During the extrusion process, the temperature of the pipe is high and needs to be gradually cooled down by the cooling bed to ensure the dimensional stability, physical properties and appearance quality of the pipe. The cooling bed usually uses air cooling or water cooling to take away the heat of the pipe, so that it reaches the appropriate temperature and performance requirements, and prepares for subsequent cutting, packaging and other processes.

[0003] For example, the utility model with authorization announcement number CN220946273U discloses a large-diameter PE pipe cooling bed that prevents PE pipe deformation. The cooling seat can limit the PE pipe to prevent the PE pipe from shaking due to wind force during the cooling process, thereby affecting the smooth and efficient cooling work. At the same time, through the movable connection between the slider and the slide slot, the cooling plate can be replaced regularly, effectively extending the service life and use value of the cooling plate.

[0004] This prior art also has the following problems when used:

[0005] The air outlet is arranged above the PE pipe, which is not convenient for the cold air to blow evenly in all directions of the PE pipe, and uneven cooling is prone to occur. Therefore, we propose a large-diameter PE pipe cooling bed that prevents PE pipe deformation in order to solve the above problems. Utility Model Content

The outer end of the second gear 14 is meshed and connected with a first gear 12. The inner end of the first gear 12 is snap - fitted with a cleaning and water - absorbing ring 13. The outer end of the cooling bed main body 1 is fixedly installed with a motor drive box 8. The inner end of the motor drive box 8 rotates a rotating rod 9. The outer end of the rotating rod 9 is fixedly installed with a conveyor roller 10, which can automatically perform circumferential and uniform air cooling on the PE pipe during transportation, with high - efficiency and uniform cooling.

[0024] The rotating rod 9 is rotatably installed at the inner end of the cooling bed main body 1, and the conveying rollers 10 are equidistantly arranged on the inner side of the cooling bed main body 1. The cooling frame 6 has an annular structure, and the cooling frame 6 and the conveying rollers 10 are alternately arranged inside the cooling bed main body 1. An air extraction box 15 is fixedly installed at the upper end of the cooling bed main body 1, and an air extraction pump 16 is fixedly installed at the inner end of the air extraction box 15. An air inlet 17 is fixedly installed at the outer end of the air extraction pump 16, and an air outlet 18 is fixedly installed at the upper end of the air extraction pump 16.

[0025] Specific working principle:

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, when using this large-diameter PE pipe cooling bed for preventing PE pipe deformation, the PE pipe to be cooled is transported through the cleaning and water-absorbing ring 13 to the inside of the conveying roller 10 by the conveying device. The servo motor 11 drives the second gear 14 to rotate. When the second gear 14 rotates, it meshes with the first gear 12, driving the first gear 12 to rotate at a constant speed. When the first gear 12 rotates, the round rod installed at the rear end of the first gear 12 slides inside the ring installed inside the cooling bed main body 1 to help the first gear 12 stay stable. The first gear 12 drives the cleaning and water-absorbing ring 13 to rotate and wipe on the surface of the PE pipe to remove water stains, etc. on the surface of the PE pipe, and then enters the inside of the cooling bed main body 1 for air cooling. When the motor inside the motor drive box 8 drives the rotating rod 9 to rotate, it drives the conveying roller 10 to rotate. The conveying roller 10 transports the PE pipe to the inside of the cooling frame 6. The refrigeration box 3 cools the air. The blower 4 extracts cold air and transports it to the inside of the cooling frame 6 through the connecting pipe 5, and then evenly blows on the surface of the PE pipe from the air outlet 7 for cooling. The air outlets 7 are distributed at equal angles to evenly cool the PE pipe. The air extraction pump 16 extracts the relatively humid air inside the cooling bed main body 1 through the air inlet 17 and discharges it from the air outlet 18 to ensure the cooling effect. The above completes a series of operations of this large-diameter PE pipe cooling bed for preventing PE pipe deformation.
