In the production process of ultra-high molecular weight polyethylene pipes, the requirements for equipment are extremely high. The production of this type of pipe requires multiple key steps to ensure the quality and performance of the final product.

[0003] Traditional pipe production equipment often has some shortcomings. For example, in terms of raw material processing, there is a lack of effective crushing mechanism, which leads to uneven raw material particle size, which is easy to cause uneven plasticization after entering the extrusion stage, affecting the density and mechanical properties of the pipe, increasing the risk of internal defects, and the material may not be fully crushed before entering the molding stage, affecting the quality of the final product; in terms of temperature control, traditional equipment is difficult to achieve temperature gradient control and cannot meet the segmented temperature requirements of ultra-high molecular weight polyethylene pipes in different production stages, which makes it difficult for the plasticization effect and molding quality of the pipe to reach the optimal state, and the molecular structure is not regular, thus affecting the strength, toughness and corrosion resistance of the pipe; in the cooling stage, the cooling method of traditional equipment is single and the cooling effect is poor, which easily leads to uneven cooling of the pipe, deformation and internal stress concentration.

A cover plate 15 is fixedly mounted on the top of the pre-treatment tank 14, so that the motor 18 can obtain stable support through the fixing plate 17. When the motor 18 is working, it drives the crushing components in the pre-treatment tank 14 to operate. The material enters the pre-treatment tank 14 from the feed pipe 16, and the feed pipe 16 penetrates the cover plate 15 to ensure that the material accurately enters the pre-treatment tank 14. The pre-treatment tank 14 is fixedly mounted on the top of the feed box 6 and the bottom penetrates the feed box 6, so that the crushed material can be smoothly introduced into the feed box 6 for subsequent processing.

A fixed plate 17 is fixedly connected to one side of the feed pipe 16, and a motor 18 is fixedly installed on the top of the fixed plate 17, so that the material can smoothly enter the inside of the pretreatment tank 14 through the feed pipe 16.

The feed pipe 16 passes through the cover plate 15 to ensure the smooth material conveying path, and also makes the whole structure more compact, improving the space utilization rate of the equipment. The fixed plate 17 plays a role in supporting the motor 18, ensuring that the motor 18 remains stable during the working process, thereby ensuring the efficient performance of the crushing work.

[0038] As attached Figure 1 , 2 As shown in Figures 3, 4, 6 and 8, a first gear 19 is fixedly connected to the output end of the motor 18, a second gear 20 is meshed on one side of the first gear 19, a rotating shaft 21 is fixedly connected inside the first gear 19 and the second gear 20, a crushing roller 22 is fixedly sleeved on the outer side of the rotating shaft 21, and the rotating shaft 21 is rotatably connected to the feed pipe 16, so that after the motor 18 is started, the first gear 19 at the output end is driven to rotate, the first gear 19 drives the second gear 20 to rotate through the meshing action, and the rotating shaft 21 fixedly connected inside the first gear 19 and the second gear 20 rotates accordingly, thereby driving the crushing roller 22 fixedly sleeved on the outer side to rotate, and the material entering the pretreatment tank 14 from the feed pipe 16 is crushed. The rotating connection between the rotating shaft 21 and the feed pipe 16 ensures that the rotating shaft 21 can rotate smoothly without being hindered by the feed pipe 16, so that the crushing work can be carried out stably and efficiently.

[0039] As attached Figure 1 , 2, 5, and 6, the cooling mechanism includes a meandering heat exchange tube 23, which is sleeved on the outside of the forming tube 8. A support platform 30 is fixedly connected to one side of the equipment box 1, and a fixed water tank 24 is fixedly installed on the top of the electric heating rod 13. An inlet pipe 25 and an outlet pipe 26 are fixedly connected between the meandering heat exchange tube 23 and the fixed water tank 24. A cooling block 37 and a circulating pump 36 are sequentially installed between the inlet pipe 25 and the outlet pipe 26, so that the coolant in the fixed water tank 24 can be circulated in the water inlet pipe 25, the meandering heat exchange tube 23, and the outlet pipe 26 through the action of the circulating pump 36. The heat of the material in the forming tube 8 is effectively absorbed by the cooling block 37, and the cooling block 37 circulates between the cooling block 37. The circular heat exchange tube 23 is sleeved on the outside of the forming tube 8, which can effectively absorb the heat of the material in the forming tube 8 and cool it. The cooling block 37 can further reduce the temperature of the coolant to ensure that the coolant can continue to perform cooling work efficiently. The fixed water tank 24 is installed on the support platform 30 on the top of the electric heating rod 13. The position is stable and can provide sufficient coolant for the cooling system. This structural design enables the cooling mechanism to stably and efficiently cool the material in the forming tube 8, thereby improving production efficiency and product quality.

[0040] As attached Figure 1 , 2 As shown in Figures 5, 6, and 7, a heat dissipation fin 27 is fixedly connected to the bottom of the cooling block 37, and the number of the heat dissipation fins 27 is set to be multiple. The bottoms of the multiple heat dissipation fins 27 sequentially penetrate the fixed water tank 24 and the support platform 30 and extend to the bottom of the support platform 30. The bottom of the support platform 30 is fixedly connected to a plurality of support columns 31, so that when the cooling block 37 cools the coolant, the heat can be quickly dissipated through the multiple heat dissipation fins 27 arranged at the bottom. The multiple heat dissipation fins 27 sequentially penetrate the fixed water tank 24 and the support platform 30 and extend to the bottom of the support platform 30, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. The multiple support columns 31 fixedly connected to the bottom of the support platform 30 provide stable support for the entire cooling mechanism, ensuring the stability of the equipment during the cooling process, thereby ensuring that the cooling work can be carried out continuously and efficiently.

[0041] As attached Figure 1 , 2 As shown in Figures 5, 6 and 7, a fixed vertical plate 28 is fixedly connected to one side of the bottom of the support platform 30, and a fan 29 is fixedly installed on the front side of the fixed vertical plate 28. One end of the fan 29 passes through the fixed vertical plate 28 and extends to one side of the fixed vertical plate 28, so that after the fan 29 is started, it can blow air to the heat dissipation fins 27, accelerate the heat dissipation speed of the heat dissipation fins 27, and improve the cooling efficiency of the cooling block 37 for the coolant. The fixed vertical plate 28 provides a stable installation position for the fan 29, ensuring that the fan 29 will not shake during operation, thereby being able to continuously and stably provide cooling air for the heat dissipation fins 27.

[0042] As attached Figure 1 , 2As shown in Figures 5 and 6, a connecting water pipe 32 is fixedly connected to the bottom of the support platform 30, the top of the meandering heat exchange tube 23 passes through the support platform 30 and extends to the top thereof, and an annular water pipe 33 is fixedly connected to the top of the meandering heat exchange tube 23, and a plurality of water spray heads 34 are fixed inside the annular water pipe 33, so that the connecting water pipe 32 can transport water or other cooling medium to the annular water pipe 33 at the top of the meandering heat exchange tube 23. The plurality of water spray heads 34 inside the annular water pipe 33 can evenly spray the cooling medium on the parts that need cooling, thereby improving the cooling effect. The top of the meandering heat exchange tube 23 passes through the support platform 30 and extends to the top thereof, so that the structure of the entire cooling system is more compact, which is convenient for the transportation and distribution of the cooling medium, thereby ensuring the efficient cooling work.

[0043] As attached Figure 1 , 2 As shown in Figures 5 and 6, the meandering heat exchange tube 23 is made of copper material, and the extruded tube 7 and the formed tube 8 are made of high temperature resistant and corrosion resistant stainless steel material, so as to increase the service life while ensuring the heat exchange effect.

[0044] As attached Figure 1 , 2 As shown in Figures 5, 6 and 9, the length of the first heat-conducting sleeve 10 is greater than the width of the second heat-conducting sleeve 11. Both the first heat-conducting sleeve 10 and the second heat-conducting sleeve 11 are made of aluminum alloy to facilitate heating of the raw materials inside the extruded tube 7.

[0045] Working principle of the present invention: During the use of the ultra-high molecular weight polyethylene pipe production equipment provided by the present invention, the raw material enters the pretreatment tank 14 through the feed pipe 16, the motor 18 is started, driving the first gear 19 to rotate, the first gear 19 is meshed with the second gear 20, so that the two rotating shafts 21 rotate at the same time, and the crushing roller 22 outside the rotating shaft 21 crushes the raw material to crush larger particles into smaller particles for better plasticization and extrusion later. The pretreated raw material falls into the feed box 6, the driving device 2 is started, and the gear box 4 is driven to work through the transmission shaft 3. The driving screw 9 at the output end of the gear box 4 starts to rotate, pushing the raw material from the feed box 6 to the extrusion pipe 7, and the feed box 6 is driven to extrusion pipe 7. The electric heating rod 13 at the bottom of the inner wall of the feed box 6 preliminarily heats the raw material to prevent the raw material from being blocked in the feed box 6. The raw material is further plasticized and extruded in the extrusion tube 7. The first heat-conducting sleeve 10 outside the extrusion tube 7 and the heating wire 12 inside the second heat-conducting sleeve 11 heat the extrusion tube 7. Since the length of the first heat-conducting sleeve 10 is greater than the width of the second heat-conducting sleeve 11, the temperature gradient control of different areas can be achieved, so that the raw material is gradually heated up in the extrusion tube 7 and fully plasticized. The plasticized raw material enters the molding tube 8 to form a pipe of a desired shape. Due to the special molecular structure of the ultra-high molecular weight polyethylene pipe, different temperatures are required at different production stages to achieve the best plasticizing effect and molding quality.

[0046] The meandering heat exchange tube 23 performs preliminary cooling on the pipe in the formed pipe 8, and the circulating pump 36 is started to transport the cooling water in the fixed water tank 24 to the meandering heat exchange tube 23 through the water inlet pipe 25. The cooling water exchanges heat with the formed pipe 8 in the meandering heat exchange tube 23, absorbs the heat of the pipe, and then returns to the fixed water tank 24 through the water outlet pipe 26. The cooling block 37 and the heat dissipation fins 27 further reduce the temperature of the cooling water. The cooling water that has absorbed the heat passes through the cooling block 37, and the cooling block 37 passes through the multiple heat dissipation fins 22 at the bottom. 7 dissipates heat into the air to reduce the temperature of the cooling water. The fan 29 assists in heat dissipation. The fan 29 starts to blow air to the heat dissipation fins 27 to accelerate the flow of air around the heat dissipation fins 27 and improve the heat dissipation efficiency. The annular water pipe 33 and the water spray head 34 perform spray cooling. The connecting water pipe 32 transports the cooling water to the annular water pipe 33 at the top of the meandering heat exchange tube 23. The multiple water spray heads 34 in the annular water pipe 33 spray cooling water to the forming tube 8 to further cool the pipe material and ensure that the pipe material is quickly cooled and shaped.
