Description

Technical Field

[0001] This utility model relates to the field of cable cooling technology, specifically a cooling device for cable extrusion. Background Technology

[0002] Cable material is an indispensable material for the preparation of the outer sheath of wires and cables. Generally, cable material is processed by mixing various raw materials at high temperature and then extruding them using an extruder. However, the temperature of the extruded cable is often high, so a cooling device is needed to cool the extruded cable.

[0003] Cooling devices for cable extrusion typically include a water tank cooling system. The structure and principle of a water tank cooling system are as follows: Structure: The water tank cooling system consists of a water tank, a water pump, water circulation pipes, nozzles, etc., and is usually installed at the outlet of the cable extruder. Principle: When the extruded cable passes through the water tank cooling system, the water pump sends cooling water into the water tank through the water circulation pipes. The cable is immersed in the cooling water, and the cooling water is evenly sprayed onto the cable surface through the nozzles, absorbing heat from the cable, thereby reducing the cable temperature and solidifying the outer layer of the cable.

[0004] Existing cooling devices typically only cool extruded cables in a single way, resulting in poor cooling performance and affecting the uniformity of cable cooling. Therefore, a cooling device for cable extrusion is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a cooling device for cable extrusion.

[0006] The technical solution adopted by this utility model to solve its technical problem is a cooling device for cable extrusion, including a base, a water-cooled box mounted on the base, a control panel mounted on the outer wall of the water-cooled box, a water-cooled tank inside the water-cooled box containing cooling water, two guide rollers symmetrically and rotatably mounted on the inner wall of the water-cooled tank, an aeration pipe fixedly mounted on the inner wall of the water-cooled tank, multiple diaphragms installed inside the aeration pipe, the diaphragms having tiny self-closing holes, a first ventilation conduit connected to the aeration pipe, an air pump connected to the other end of the first ventilation conduit, the air pump fixedly connected to the outer wall of the water-cooled box, a second ventilation conduit connected to the other end of the second ventilation conduit, a liquid nitrogen bottle placed on the base, and a first air-cooling pipe mounted on one side of the water-cooled box via a fixed base. The first air-cooling pipe has a cavity inside, and multiple exhaust holes are formed on the inner wall of the first air-cooling pipe. A first air guide pipe is installed on the side wall of the first air-cooling pipe, and an air guide box is connected to the other end of the first air guide pipe. The air guide box is fixedly installed on the base, and a fan is installed on the air guide box via a base. An exhaust pipe is installed on the fan and connected to the air guide box. The extruded cable enters the first air-cooling pipe, and cold air blows on the extruded cable to perform the first stage of cooling. Then the cable moves into the water-cooling tank, and the cable is immersed in the cooling water of the water-cooling tank to achieve the second stage of cooling. Finally, after the cable is removed from the water-cooling tank, the cold air discharged from the second air-cooling pipe performs the third stage of cooling on the cable. This structure can perform multi-stage cooling of the cable, achieve uniform cooling of the cable, and is beneficial to improving the cooling effect of the cable.

[0007] Preferably, a second air-cooling pipe is mounted on the other side wall of the water-cooled box via a fixed seat. The second air-cooling pipe has the same internal structure as the first air-cooling pipe. A second air guide pipe is mounted on the second air-cooling pipe, and the other end of the second air guide pipe is connected to an air guide box. A first conveying assembly is mounted on the side wall of the water-cooled box, and a second conveying assembly is mounted on the side wall of the water-cooled box via a fixed seat. The first and second conveying assemblies have the same structure. The first conveying assembly includes a fixed frame, on which two sets of conveying rollers are rotatably mounted. Gears are fixedly mounted on the output shafts of the two sets of conveying rollers. The gears mesh with each other, and a drive motor is mounted on the side wall of the fixed frame via a base. The output shaft of the drive motor is fixedly connected to the output shaft of one of the conveying rollers. After the cable is removed from the water-cooling tank, the first and second conveying components operate, and the conveying rollers transport the cable, achieving stable movement of the cable. During this process, the cable removed from the water-cooling tank passes through the second air-cooling pipe. The cold air discharged from the second air-cooling pipe cools the cable and dries the water stains on the cable surface, thus cleaning the water stains on the cable surface and improving the cleanliness of the cable.

[0008] The advantages of this utility model are:

[0009] 1. This utility model involves extruding a cable into a first air-cooling pipe, where cold air blows onto the extruded cable for the first stage of cooling. The cable then moves into a water-cooling tank, where it is immersed in cooling water, achieving the second stage of cooling. Finally, after the cable exits the water-cooling tank, cold air from the second air-cooling pipe provides the third stage of cooling. This structure allows for multi-stage cooling of the cable, achieving uniform cooling and improving the overall cooling effect.

[0010] 2. In this utility model, after the cable is removed from the water-cooling tank, the first and second conveying components operate, and the conveying rollers transport the cable, achieving stable movement of the cable. During this process, the cable removed from the water-cooling tank passes through the second air-cooling pipe, and the cold air discharged from the second air-cooling pipe cools the cable.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4 As shown, a cooling device for cable extrusion includes a base 1, a water-cooled box 2 mounted on the base 1, a control panel 3 mounted on the outer wall of the water-cooled box 2, a water-cooled tank 4 inside the water-cooled box 2 containing cooling water, two guide rollers 5 symmetrically and rotatably mounted on the inner wall of the water-cooled tank 4, an aeration pipe 6 fixedly mounted on the inner wall of the water-cooled tank 4, multiple diaphragms 7 installed inside the aeration pipe 6, each diaphragm having a small self-closing hole, a first ventilation conduit 8 connected to the aeration pipe 6, the other end of the first ventilation conduit 8 connected to an air pump 9 fixedly connected to the outer wall of the water-cooled box 2, the other end of the air pump 9 connected to a second ventilation conduit 10, the other end of the second ventilation conduit 10 connected to a liquid nitrogen bottle 11 placed on the base 1, a first air-cooling pipe 12 mounted on one side of the water-cooled box 2 via a fixed seat, a cavity 13 formed inside the first air-cooling pipe 12, and a cavity 13 formed on the inner wall of the first air-cooling pipe 12. Multiple exhaust holes 14 are provided. A first air guide pipe 15 is installed on the side wall of the first air-cooling pipe 12. The other end of the first air guide pipe 15 is connected to an air guide box 16. The air guide box 16 is fixedly installed on the base 1. A fan 17 is installed on the air guide box 16 through a base. An exhaust pipe 18 is installed on the fan 17 and connected to the air guide box 16. During operation, the existing cooling device can usually only cool the extruded cable in a single way, resulting in poor cooling effect and affecting the uniformity of cable cooling. The extruded cable enters the first air-cooling pipe 12. The fan 17 operates and introduces cold air into the air guide box 16 from the exhaust pipe 18. Then, the cold air enters the cavity 13 of the first air-cooling pipe 12 from the first air guide pipe 15 and is discharged from multiple exhaust holes 14. The cold air blows on the extruded cable and performs the first stage of cooling on the extruded cable.

[0020] The cable is then moved into the water-cooling tank 4, where two guide rollers 5 guide it. The cable moves along the bottom wall of the water-cooling tank 4 and is immersed in the cooling water. During this process, the air pump 9 operates, introducing nitrogen from the liquid nitrogen bottle 11 into the first ventilation conduit 8, and then from the first ventilation conduit 8 into the aeration pipe 6. The diaphragm 7 on the aeration pipe 6 is made of rubber and has tiny self-closing pores. The principle of the aeration pipe 6 is that the micropores of the aeration pipe 6 automatically open under nitrogen pressure, allowing nitrogen to enter the cooling water for nitrogen filling. If the pressure disappears, the micropores of the aeration pipe 6 automatically close to prevent cooling water from flowing back into the micropores. In other words, nitrogen diffuses out from the aeration pipe 6 in the form of bubbles, thereby cooling the cooling water through liquid nitrogen. The diffused bubbles also agitate the cooling water to a certain extent, achieving uniform cooling of the cable and realizing the second stage of cooling of the cable.

[0021] Finally, after the cable is removed from the water-cooled tank 4, it will pass through the second air-cooling pipe 19. The cold air discharged from the second air-cooling pipe 19 will provide a third stage of cooling for the cable. This structure can provide multi-stage cooling for the cable, achieving uniform cooling and improving the cooling effect of the cable.

[0022] Please see Figure 5As shown, a second air-cooling pipe 19 is mounted on the other side wall of the water-cooled box 2 via a fixed seat. The second air-cooling pipe 19 has the same internal structure as the first air-cooling pipe 12. A second air guide pipe 20 is mounted on the second air-cooling pipe 19, and the other end of the second air guide pipe 20 is connected to the air guide box 16. A first conveying assembly is mounted on the side wall of the water-cooled box 2, and a second conveying assembly is mounted on the side wall of the water-cooled box 2 via a fixed seat. The first and second conveying assemblies have the same structure. The first conveying assembly includes a fixed frame 21, on which two sets of conveying rollers 22 are rotatably mounted. Gears 23 are fixedly mounted on the output shafts of the two sets of conveying rollers 22, and the two gears 23 mesh with each other. A drive motor 24 is mounted on the side wall of the fixed frame 21 via a base, and the output shaft of the drive motor 24 is fixedly connected to the output shaft of one of the conveying rollers 22. During operation, existing cooling devices typically use water cooling to cool the extruded cable. The method of cooling the cable is not ideal, but it is difficult to clean the water stains on the cable surface after cooling, resulting in poor cable cleanliness. After the cable is removed from the water-cooling tank 4, the first and second conveying components operate, that is, the drive motor 24 operates, driving one of the conveying rollers 22 to rotate. One of the conveying rollers 22 drives the gear 23 on it to rotate, and the gear 23 drives the other gear 23 to rotate. The two gears 23 rotate synchronously relative to each other, and the two gears 23 drive the two conveying rollers 22 to rotate synchronously relative to each other. The conveying rollers 22 on the first and second conveying components transport the cable, realizing the stable movement of the cable. During this process, the cable removed from the water-cooling tank 4 will pass through the second air-cooling pipe 19. The cold air discharged from the second air-cooling pipe 19 cools the cable and dries the water stains on the cable surface, thus cleaning the water stains on the cable surface and improving the cleanliness of the cable.

[0023] Working principle: Existing cooling devices typically only cool extruded cables using a single method, resulting in poor cooling effect and affecting the uniformity of cooling. The extruded cable enters the first air-cooling pipe 12. A fan 17 draws cold air from the exhaust pipe 18 into the air box 16. The cold air then enters the cavity 13 of the first air-cooling pipe 12 through the first air guide pipe 15 and exits through multiple exhaust holes 14. This cold air blows onto the extruded cable, providing the first stage of cooling. Afterward, the cable moves into the water-cooling tank 4, where two guide rollers 5 guide the cable, causing it to move along the bottom wall of the water-cooling tank 4. The cooling water is immersed in the water-cooling tank 4. During this process, the air pump 9 operates, and the air pump 9 introduces nitrogen gas from the liquid nitrogen bottle 11 into the first venting conduit 8, and then from the first venting conduit 8 into the aeration pipe 6. The diaphragm 7 on the aeration pipe 6 is made of rubber and has tiny self-closing pores. The principle of the aeration pipe 6 is that when it is working, the micropores of the aeration pipe 6 will automatically open under nitrogen pressure, and nitrogen gas will enter the cooling water for nitrogen filling. If the pressure is released, the micropores of the aeration pipe 6 will automatically close to prevent the cooling water from flowing back into the micropores. That is, nitrogen gas diffuses out from the aeration pipe 6 in the form of bubbles, thereby cooling the cooling water with liquid nitrogen, and the diffused bubbles can also cool the cooling water to a certain extent. The agitation achieves uniform cooling of the cable, realizing the second stage of cooling. After the cable exits the water-cooling tank 4, it passes through the second air-cooling pipe 19, where the cold air discharged from the second air-cooling pipe 19 provides the third stage of cooling. This structure allows for multi-stage cooling of the cable, achieving uniform cooling and improving the cooling effect. Existing cooling devices typically use water cooling during the cooling process of extruded cables, but it is difficult to clean water stains from the cable surface after cooling, resulting in poor cable cleanliness. By using the first and second conveying components after the cable exits the water-cooling tank 4, the cooling process is improved. The drive motor 24 operates, driving one of the conveying rollers 22 to rotate. One of the conveying rollers 22 drives the gear 23 on it to rotate, and the gear 23 drives the other gear 23 to rotate. The two gears 23 rotate synchronously relative to each other, and the two gears 23 drive the two conveying rollers 22 to rotate synchronously relative to each other. The conveying rollers 22 on the first conveying component and the second conveying component convey the cable, realizing the stable movement of the cable. During this process, the cable removed from the water-cooling tank 4 will pass through the second air-cooling pipe 19. The cold air discharged from the second air-cooling pipe 19 cools the cable and dries the water stains on the surface of the cable, thus cleaning the water stains on the surface of the cable and improving the cleanliness of the cable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
