[0001] The utility model relates to the technical field of PE pipe production, in particular to a cooling device for PE pipe production. Background Art

[0002] During the PE pipe production process, the cooling device can accelerate the cooling process of the PE pipe, allowing it to reach the required hardness and stability more quickly, so that subsequent processing, packaging and transportation can be carried out earlier, which helps to shorten the production cycle and improve production efficiency.

[0003] For example, the patent document with publication number CN219600157U discloses a rapid cooling device for PE pipe production, which includes a fixed frame, a wire trough and a spray cooling mechanism. The entire sliding table is reciprocated by a drive box, and cooperates with the upper spray plate to circulate and spray cool the lower PE pipe. In the above patent, the outside of the PE pipe is mainly cooled. However, in the production process of PE pipes, especially in the manufacture of pipes with higher pressure resistance and compression resistance, relying solely on external cooling is not enough to ensure that the inside of the PE pipe also achieves the ideal cooling effect. Insufficient internal cooling will lead to excessive temperature difference between the inside and outside of the PE pipe, thereby generating stress and affecting the overall quality and performance of the pipe. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a cooling device for PE pipe production, which solves the problem in the existing technology that relying solely on external cooling is not enough to ensure that the inside of the PE pipe also achieves the ideal cooling effect. Insufficient internal cooling will lead to excessive temperature difference between the inside and outside of the PE pipe, thereby generating stress and affecting the overall quality and performance of the pipeline.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A cooling device for PE pipe production, comprising a fixing frame, a mounting plate fixedly connected to the front of the fixing frame, a drive motor fixedly connected to the mounting plate, an output end of the drive motor extending to the back of the mounting plate, and a pinion fixedly sleeved on the output end of the drive motor;

[0006] A water collecting trough is provided inside the fixed frame, and a first roller and a second roller are rotatably connected to both sides of the water collecting trough. One end of the first roller passes through and extends to the front of the water collecting trough, and a large gear is fixedly sleeved on one end of the first roller. The teeth of the small gear are engaged with the teeth of the large gear. PE pipes are placed on the first roller and the second roller, and the bottom of the PE pipe is located inside the water collecting trough.

[0007] Furthermore, support plates are fixedly connected to the tops of the front and back sides of the fixing frame.

[0008] Furthermore, both sides of the inner wall of the fixing frame are fixedly connected with a fixing seat, an inclined plate is rotatably connected to the fixing seat, and a stabilizing roller is rotatably connected between the front and rear inclined plates, and the stabilizing roller abuts against the outer surface of the PE pipe.

[0009] Furthermore, both sides of the top of the support plate are rotatably connected to a first threaded rod, the inclined plate is rotatably connected to a second threaded rod, and a threaded sleeve is threaded between the first threaded rod and the second threaded rod.

[0010] Furthermore, a plurality of insertion holes are equidistantly provided on the front surface of the inclined plate, a pin is movably inserted into the top of the second threaded rod, and one end of the pin is movably inserted into one of the insertion holes.

[0011] Furthermore, reinforcement plates are fixedly connected to both the left and right sides of the fixing frame.

[0012] By means of the above technical solution, the utility model provides a cooling device for PE pipe production, which has at least the following beneficial effects:

[0013] 1. The cooling device for PE pipe production places the PE pipe on the first and second rollers and ensures that the PE pipe is completely immersed in the coolant in the sump. Subsequently, the drive motor is started. The operation of the drive motor will drive the small gear to start rotating. The rotation of the small gear drives the large gear to rotate. The rotation of the large gear causes the first roller to start rotating. Since the first roller is in direct contact with the PE pipe, its rotation will drive the PE pipe as a whole to rotate. At the same time, the second roller serves as an auxiliary support, allowing the coolant to effectively cool the inner and outer surfaces of the PE pipe at the same time, avoiding the problem of insufficient cooling inside the PE pipe, thereby reducing the risk of excessive temperature difference between the inside and outside of the PE pipe and ensuring the quality and stability of the PE pipe during the production process.

[0014] 2. This cooling device for PE pipe production involves inserting a pin into the socket of the inclined plate, connecting the top of the second threaded rod to the inclined plate, and rotating the threaded sleeve clockwise, causing the first and second threaded rods to move in opposite directions. The second threaded rod exerts tension on the inclined plate, causing the inclined plate and its stabilizing roller to approach the outer surface of the PE pipe until the stabilizing roller makes close contact with the outer surface of the PE pipe. This ensures the stability of the PE pipe during rotation and prevents poor cooling or pipe damage caused by shaking or vibration. The position of the stabilizing roller can be easily adjusted by rotating the threaded sleeve, making it adaptable to PE pipes of different outer diameters without replacing or adjusting other components, thereby improving the device's flexibility and versatility.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 A cooling device for PE pipe production includes a fixing frame 1, a mounting plate 2 is fixedly connected to the front of the fixing frame 1, a driving motor 3 is fixedly connected to the mounting plate 2, an output end of the driving motor 3 extends to the back of the mounting plate 2, and a pinion 4 is fixedly sleeved on the output end of the driving motor 3;

[0024] A water collecting trough 5 is provided inside the fixed frame 1, and the first roller 6 and the second roller 7 are rotatably connected on both sides of the water collecting trough 5. One end of the first roller 6 passes through and extends to the front of the water collecting trough 5. A large gear 8 is fixedly sleeved on one end of the first roller 6. The teeth of the small gear 4 are engaged with the teeth of the large gear 8. PE pipes 9 are placed on the first roller 6 and the second roller 7, and the bottom of the PE pipe 9 is located inside the water collecting trough 5. Place the PE tube 9 on the first roller 6 and the second roller 7, and ensure that the PE tube 9 is completely immersed in the coolant in the sump 5. Then, start the drive motor 3. The operation of the drive motor 3 will drive the small gear 4 to start rotating. The rotation of the small gear 4 drives the large gear 8 to rotate. The rotation of the large gear 8 causes the first roller 6 to start rotating. Since the first roller 6 is in direct contact with the PE tube 9, its rotation will drive the PE tube 9 to rotate as a whole. At the same time, the second roller 7 serves as an auxiliary support, and the coolant can effectively cool the inner and outer surfaces of the PE tube 9 at the same time, avoiding the problem of insufficient cooling inside the PE tube 9, thereby reducing the risk of excessive temperature difference between the inside and outside of the PE tube 9, and ensuring the quality and stability of the PE tube 9 during the production process.

[0025] The tops of the front and back sides of the fixing frame 1 are fixedly connected to support plates 11. A fixing seat 12 is fixedly connected to both sides of the inner wall of the fixing frame 1. An inclined plate 13 is rotatably connected to the fixing seat 12. A stabilizing roller 19 is rotatably connected between the front and rear inclined plates 13. The stabilizing roller 19 abuts the outer surface of the PE tube 9. A first threaded rod 15 is rotatably connected to both sides of the top of the support plate 11. A second threaded rod 17 is rotatably connected to the inclined plate 13. A threaded sleeve 16 is threadedly mounted between the first and second threaded rods 15, 17. When the threaded sleeve 16 is rotated clockwise, the first and second threaded rods 15, 17 move in opposite directions. The second threaded rod 17 generates a pulling force on the inclined plate 13, causing the inclined plate 13 and the stabilizing roller 19 thereon to move closer to the outer surface of the PE tube 9 until the stabilizing roller 19 is in close contact with the outer surface of the PE tube 9. This ensures that the PE tube 9 remains stable during rotation and prevents poor cooling or damage to the pipe due to shaking or vibration. Furthermore, the position of the stabilizing roller 19 can be conveniently adjusted by rotating the threaded sleeve 16 so that it can adapt to PE pipes 9 of different outer diameters without replacing or adjusting other components, thereby improving the flexibility and versatility of the device.

[0026] The front of the tilting plate 13 is provided with multiple equally spaced insertion holes 14. A latch 18 is movably inserted into the top of the second threaded rod 17, with one end of the latch 18 movably inserted into one of the insertion holes 14. Inserting the latch 18 into the insertion hole 14 of the tilting plate 13 facilitates connecting the top of the second threaded rod 17 to the tilting plate 13. Inserting the latch 18 into different insertion holes 14 also facilitates adjusting the relative position of the second threaded rod 17 and the tilting plate 13. When the latch 18 is removed, the stabilizing roller 19 can be flipped to the outside of the fixed frame 1, facilitating the placement of the PE pipe 9 on the first and second rollers 6 and 7.

[0027] The left and right sides of the fixing frame 1 are both fixedly connected with reinforcement plates 10. The reinforcement plates 10 enhance the overall structural stability of the fixing frame 1.

[0028] Working principle: Place the PE tube 9 on the first roller 6 and the second roller 7, and ensure that the PE tube 9 is completely immersed in the coolant in the water collecting tank 5;

[0029] Insert the latch 18 into the insertion hole 14 of the tilting plate 13, connect the top of the second threaded rod 17 to the tilting plate 13, and rotate the threaded sleeve 16 clockwise so that the first threaded rod 15 and the second threaded rod 17 will move in opposite directions. The second threaded rod 17 will generate a pulling force on the tilting plate 13, so that the tilting plate 13 and the stabilizing roller 19 thereon will move closer to the outer surface of the PE tube 9 until the stabilizing roller 19 is in close contact with the outer surface of the PE tube 9.

[0030] Start the drive motor 3. The operation of the drive motor 3 will drive the small gear 4 to start rotating. The rotation of the small gear 4 drives the large gear 8 to rotate. The rotation of the large gear 8 causes the first roller 6 to start rotating. Since the first roller 6 is in direct contact with the PE tube 9, its rotation will drive the PE tube 9 to rotate as a whole. At the same time, the second roller 7 serves as an auxiliary support, and the coolant can effectively cool the inner and outer surfaces of the PE tube 9 at the same time, avoiding the problem of insufficient cooling inside the PE tube 9, thereby reducing the risk of excessive temperature difference between the inside and outside of the PE tube 9, and ensuring the quality and stability of the PE tube 9 during the production process.
