[0002] Polyethylene pipelines are high-molecular material pipelines made of polyethylene resin as the main raw material through extrusion molding. Because of their characteristics such as corrosion resistance, good flexibility, and long service life, they are widely used in water supply and drainage projects, gas transmission, agricultural irrigation and other fields. In the production process of polyethylene pipelines, the cooling and shaping device plays a key role.

The bottom plate 1 and the housing 2 cooperate to provide a stable basic support for the entire device, ensuring the stability of the housing 2 and its internal components during operation. A plurality of mounting frames 3 are fixedly connected inside the housing 2. The mounting frames 3 are used to carry subsequent components. An external gear ring 4 is fixedly connected to the outer wall of the mounting frame 3. The external gear ring 4 cooperates with the subsequent drive assembly to realize the surrounding operation of the slider 6. A chute 5 is provided on the outer wall of the mounting frame 3. The chute 5 provides a sliding track for the slider 6, enabling the slider 6 to move along a specific direction on the mounting frame 3. A slider 6 is slidably connected inside the chute 5. The slider 6 slides inside the chute 5 to achieve the effect of circular cooling of the pipeline. A drive assembly is provided at the bottom of the outer wall of the slider 6. The drive assembly is used to drive the slider 6 to slide along the inside of the chute 5. A housing 9 is fixedly connected to the top of the outer wall of the slider 6. The housing 9 provides an installation space for the subsequent transmission assembly and reciprocating assembly. A transmission assembly is provided inside the housing 9. The transmission assembly is used to transmit the power of the drive assembly to the reciprocating assembly, thereby driving the reciprocating assembly to work. A reciprocating assembly is provided on the top of the housing 9. The reciprocating assembly is used to achieve a specific reciprocating motion, increasing the cooling range of the pipeline. A plurality of cleaning assemblies are provided on the inner wall of the housing 2. The cleaning assemblies are used to clean the outer wall of the pipeline;

[0034] Referring to Figure 4 and Figure 5 , the drive assembly includes a motor 7. The motor 7 is fixedly connected to the outer wall of the slider 6. The motor 7 is the main power source of the entire drive assembly. By fixing the motor 7, the stability of the motor 7 during operation is ensured. A first gear 8 is fixedly connected to the output end of the motor 7. The first gear 8 is used to transmit the rotational power of the motor 7.

[0035] Referring to Figure 5, the transmission assembly includes a first rotating shaft 10 and a second rotating shaft 13. Both the first rotating shaft 10 and the second rotating shaft 13 are rotatably connected inside the housing 9. The rotation of the first rotating shaft 10 and the second rotating shaft 13 inside the housing 9 facilitates driving other subsequent components to rotate. One end of the first rotating shaft 10 is fixedly connected to a second gear 11. The second gear 11 is used to drive the first rotating shaft 10 to rotate by meshing with the first gear 8. The other end of the first rotating shaft 10 is fixedly connected to a driving bevel gear 12. The driving bevel gear 12 is used to transmit the rotational power of the first rotating shaft 10. The outer wall of the second rotating shaft 13 is fixedly connected to a driven bevel gear 14. The driven bevel gear 14 is used to receive the rotational power of the first rotating shaft 10 and change the direction of rotation.

[0036] Referring to Figure 5 , the reciprocating assembly includes a turntable 15. The turntable 15 is fixedly connected to the top of the second rotating shaft 13. By fixing the turntable 15 to the top of the second rotating shaft 13, it is convenient to drive the turntable 15 to rotate through the rotation of the second rotating shaft 13. The top edge of the turntable 15 is fixedly connected to an eccentric shaft 16. The rotation of the turntable 15 drives the eccentric shaft 16 to perform a circumferential eccentric motion, further driving other subsequent components to perform specific motions. The top of the eccentric shaft 16 is fixedly connected to a limiting sleeve 17. The limiting sleeve 17 is used to limit the rotating frame 18 on the outer wall of the eccentric shaft 16. The outer wall of the eccentric shaft 16 is slidably connected to the rotating frame 18. The rotating frame 18 performs a reciprocating motion driven by the eccentric shaft 16. The outer wall of the rotating frame 18 is fixedly connected to a first connecting rod 19. The first connecting rod 19 is used to transmit the reciprocating motion of the rotating frame 18, thereby driving the mounting plate 20 to perform a reciprocating motion. The bottom of the first connecting rod 19 is fixedly connected to the mounting plate 20. The mounting plate 20 provides a mounting basis for the installation of the nozzle 21 and realizes a reciprocating motion driven by the first connecting rod 19. The bottom of the mounting plate 20 is fixedly connected to the nozzle 21. The nozzle 21 is used to spray water to cool the pipeline and increase the cooling range of the pipeline driven by the reciprocating motion of the mounting plate 20.

[0037] Referring to Figure 6, The cleaning component includes multiple sleeves 24. The sleeves 24 are fixedly connected to the inner wall of the housing 2. The sleeves 24 are the main support structure of the entire cleaning component. At the same time, they also provide installation space for subsequent other components. A limiting plate 25 is slidably connected inside the sleeve 24. The limiting plate 25 is used to limit the second connecting rod 26 to prevent the second connecting rod 26 from sliding excessively and disengaging from inside the limiting plate 25. One side of the limiting plate 25 is fixedly connected to the second connecting rod 26. The second connecting rod 26 is used to connect the limiting plate 25 and the fixing plate 28 and transmit the movement of the limiting plate 25 to the fixing plate 28. The other side of the limiting plate 25 is fixedly connected to a spring 27. The spring 27 is used to provide elastic force to push the limiting plate 25 to slide, and further drive the fixing plate 28 to slide through the second connecting rod 26. The side of the second connecting rod 26 away from the limiting plate 25 is fixedly connected to a fixing plate 28. The fixing plate 28 provides installation space for the installation of the cleaning roller 29. A cleaning roller 29 is rotatably connected between two adjacent fixing plates 28. The cleaning roller 29 is used to clean the outer wall of the pipeline.

[0038] Refer to Figure 4 and Figure 5 , The first gear 8 meshes with the external gear ring 4. The meshing of the first gear 8 and the external gear ring 4 enables the first gear 8 to perform a circular motion along the external gear ring 4 during rotation. The first gear 8 meshes with the second gear 11. The meshing of the first gear 8 and the second gear 11 causes the first gear 8 to drive the second gear 11 to rotate during rotation.

[0039] Refer to Figure 5 , The driving bevel gear 12 meshes with the driven bevel gear 14. The meshing of the driving bevel gear 12 and the driven bevel gear 14 facilitates driving the driven bevel gear 14 to rotate through the rotation of the driving bevel gear 12 and changing the rotation direction at the same time.

[0040] Refer to Figure 5 , Two guide rods 22 are fixedly connected to the outer wall of the mounting plate 20. The outer walls of the guide rods 22 are slidably connected to the inner wall of the housing 9. The guide rods 22 are used to limit the mounting plate 20 so that the mounting plate 20 can only slide along a specified direction. A limiting block 23 is fixedly connected to the side of the guide rod 22 away from the mounting plate 20. The limiting block 23 is used to limit the guide rod 22 to prevent the guide rod 22 from sliding excessively and disengaging from inside the housing 9.

[0041] Refer to Figure 2 and Figure 6 , The cleaning roller 29 is in contact with the outer wall of the pipeline. The contact can ensure that when the pipeline passes through, the cleaning roller 29 can effectively clean the surface of the pipeline.

[0042] Working principle: After the pipe is extruded, it will enter the interior of the outer shell 2. Subsequently, by energizing and starting the motor 7, when the motor 7 is energized and started, it will rotate. When the motor 7 rotates, it will drive the first gear 8 to rotate. Since the first gear 8 meshes with the external gear ring 4 and the second gear 11, during the rotation of the first gear 8, it will slide along the outer wall of the external gear ring 4, further causing the slider 6 to slide along the interior of the chute 5 and driving the second gear 11 to rotate simultaneously. When the second gear 11 rotates, it will drive the first rotating shaft 10 to rotate, further driving the driving bevel gear 12 to rotate. Since the driving bevel gear 12 meshes with the driven bevel gear 14, when the driving bevel gear 12 rotates, it will drive the driven bevel gear 14 to rotate, further driving the second rotating shaft 13 to rotate. The rotation of the second rotating shaft 13 will drive the turntable 15 at its top to rotate. When the turntable 15 rotates, it will drive the eccentric shaft 16 at its top to perform a circumferential eccentric motion. When the eccentric shaft 16 performs a circumferential eccentric motion, it will drive the rotating frame 18 to slide reciprocally and drive the mounting plate 20 to slide reciprocally through the first connecting rod 19. When the mounting plate 20 slides reciprocally, it will drive the nozzle 21 at its bottom to slide reciprocally. This enables the nozzle 21 to cool the outer circumference of the pipe during the cooling process of the pipe. At the same time, the reciprocating motion increases the cooling area.

[0043] The cooled pipe will continue to be extruded and thus pass through the cleaning roller 29. The cleaning roller 29 cleans the surface of the pipe. During this process, the spring 27 will always push the limiting plate 25 to slide through its own elastic force, further driving the fixing plate 28 to slide through the second connecting rod 26, so that the cleaning roller 29 is always in contact with the pipe.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
