Abstract
Description
Technical Field
[0001] This utility model relates to a cooling system for cable production. Background Technology
[0002] Cooling is a crucial step in cable production, primarily to ensure rapid curing of the cable after extrusion and to maintain its physical and electrical properties. The specific reasons for the need for cooling in cable production are as follows:
[0003] 1. Curing the insulation layer and sheath
[0004] After the cable is extruded, the insulation or sheath material (such as PVC, XLPE, etc.) is in a high-temperature molten state and needs to be cooled to solidify it quickly and form a stable structure.
[0005] Insufficient cooling can lead to material deformation or uneven surfaces.
[0006] 2. Maintain dimensional stability
[0007] Cooling helps the cable to quickly set its shape, preventing dimensional deviations caused by material shrinkage or expansion.
[0008] If the cooling is uneven, the cable may develop problems such as ellipticity or eccentricity.
[0009] 3. Improve mechanical properties
[0010] Proper cooling can improve the mechanical strength, abrasion resistance, and tensile properties of cables.
[0011] Cooling too quickly or too slowly can affect the crystallinity of the material, thereby reducing its mechanical properties.
[0012] 4. Ensure electrical performance
[0013] The electrical properties of insulating materials (such as insulation resistance and dielectric strength) are closely related to the cooling process.
[0014] Uneven cooling can lead to stress concentration within the insulation layer, affecting the long-term electrical performance of the cable.
[0015] 5. Prevent material aging
[0016] Prolonged exposure to high temperatures can cause insulation materials to oxidize or degrade, while cooling can reduce the risk of material aging.
[0017] Rapid cooling can also prevent materials from undergoing chemical changes due to high temperatures.
[0018] In the existing technology, the cooling of cables is mainly water cooling, which has two main methods: spray cooling and immersion cooling.
[0019] Immersion cooling has a high cooling efficiency, but it is more troublesome to load cables. This is because the cable enters the water cooling tank at a low position, while both ends are at a high position, so loading the cable is a very troublesome task.
[0020] Based on the above problems, we designed a cooling system for cable production that facilitates the rapid loading of cables to be cooled. Utility Model Content
[0021] The technical problem to be solved by this utility model is to provide a cooling system for cable production that facilitates the rapid loading of cables to be cooled.

Recesses are provided on the left and right sides of the water-cooled tank, and support devices are installed within these recesses. A linear drive device is installed at the rear end of the water-cooled tank, and a cable presser is installed via the linear drive device.

Therefore, they should not be construed as limitations on this utility model.
[0038] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0040] See Figure 1 and Figure 2 As shown, the device includes a water-cooled tank 1. An inlet pipe 101, an outlet pipe 102, and an overflow pipe 103 are installed on the side of the water-cooled tank 1. The height of the overflow pipe 103 is higher than the height of the inlet pipe 101. The outlet pipe 102 corresponds to the bottom of the water-cooled tank 1. Recesses 2 are provided on the left and right sides of the water-cooled tank 1. A support device 3 is installed in the recesses 2. A linear drive device 4 is installed at the rear end of the water-cooled tank 1. A cable clamp 5 is installed through the linear drive device 4. After the cable clamp 5 descends, it enters the water-cooled tank 1. When the cable clamp 5 ascends to its limit position, it is higher than the upper end surface of the water-cooled tank 1.
[0041] The above technical solution facilitates the insertion of the cable to be cooled.
[0042] In actual operation, the cable presser 5 is first moved upward. At this time, the cable to be cooled is installed between the support devices 3 on both sides, and the end of the cable to be wound is pulled out to the next process. Then, the cable presser 5 is driven downward by the linear drive device 4 to press the cable into the water cooling tank 1. The cable is cooled down by the cold water in the water cooling tank 1.
[0043] Water is supplied through the inlet pipe 101 and supplied through the outlet pipe 102, so that the water temperature in the water-cooled tank 1 is always kept at a relatively low temperature to meet the cooling needs of the cable.
[0044] See Figure 2 As shown, the support device 3 includes a support shaft, and a roller body 32 is fitted on the outside of the support shaft. Multiple annular grooves 32 for positioning cables are machined on the outer wall of the roller body 31. A bearing is assembled between the roller body 31 and the support shaft. The two ends of the support shaft are fixed to the side wall of the recess 2. The cable presser 5 corresponds to the annular grooves 32.
[0045] In the above technical solution, the resistance during cable movement is reduced by using the rotatable roller 31.
[0046] The annular groove 32 allows for accurate positioning of the cable.
[0047] See Figure 1 and Figure 3 As shown, the cable presser 5 includes a housing 51, a side bracket 52 is provided at the bottom of the housing 51, a first support shaft 53 is mounted on the side bracket 52, the first support shaft 53 is parallel to the support shaft, a plurality of pulleys 54 are rotatably mounted on the first support shaft 53, a ceramic bearing is installed between the pulleys 54 and the first support shaft 53, the pulleys 54 have pulley grooves 55, the pulley grooves 55 correspond to the annular groove 32, and the housing 51 is driven to slide by the linear drive device 4.
[0048] In the above technical solution, the cable is positioned in the pulley groove 55 by the downward movement of the housing 51, and the cable is immersed in water for cooling as the housing 51 continues to move downward.
[0049] See Figure 3 As shown, a through groove 551 is provided on the side of the housing 51. An axial flow fan 552 is installed at the upper end of the housing 51. When cooling the cable, a portion of the through groove 551 is immersed in water, and the axial flow fan 552 is located above the water surface. A bent pipe 553 is installed at the blowing end of the axial flow fan 552, and the end of the bent pipe 553 is inserted into the through groove 551.
[0050] In the above technical solution, air can be blown through the bend 553. The blown air acts on the through groove 551, causing the water in the water-cooling tank 1 to flow under the action of the air force, and the water is cooled by air cooling.
[0051] See Figure 3 As shown, a one-way valve 554 is connected in series on the bend 553.
[0052] The 554 check valve allows air to flow in only one direction, preventing water from entering.
[0053] See Figure 3 As shown, the linear drive device 4 includes a frame 441. The lower end of the frame 441 is fixed to the water-cooling tank 1. A servo motor 442 is mounted on the upper end of the frame 441. A screw 443 is mounted on the output end of the servo motor 442. A bearing is fitted between the screw 443 and the frame 441. A guide rod 444 parallel to the screw 443 is mounted on the inner side of the frame 441. A Z-shaped connecting arm 445 is mounted between the guide rod 444 and the screw 443. A linear bearing 446 that cooperates with the guide rod 444 and a nut 447 that cooperates with the screw 443 are mounted on the connecting arm 445. The lower end of the connecting arm 445 is fixed to the housing 51.
[0054] In the above technical solution, the servo motor 442 is controlled by the servo controller to realize the forward and reverse rotation of the screw 443 and the speed control, thereby adjusting the height of the housing 51.
[0055] The guide rod 444 and the linear bearing 446 work together to guide the connecting arm 445.
