Description

Technical Field

[0001] This utility model belongs to the field of cable cooling technology, and in particular relates to a cable cooling device for a cable extruder. Background Technology

[0002] After the cable is wrapped with insulation, the freshly extruded insulation needs to be cooled and shaped with cooling water. When the insulated cable is immersed in water, the insulation cannot be bent because it has not been cooled. Since the cable needs to contact the upper edge of the cooling water tank, the soft insulation is prone to scratching against the upper edge of the cooling water tank, resulting in scratches on the insulation and a decrease in the quality of the cable insulation. The traditional method of using a sponge to hold the uncooled cable insulation can easily deform the insulation on the cable surface, making it impossible for the insulation to fully adhere to the cable surface.

[0003] To address these issues, we provide a cable cooling device for a cable extruder. Utility Model Content

[0004] The purpose of this utility model is to provide a cable cooling device for a cable extruder. A pre-cooling component is installed on one side of the water-cooling sleeve. A spray water curtain assembly is installed at the upper end of the pre-cooling water tank in the pre-cooling component, and an upward-lifting water curtain assembly is installed at the bottom end of the pre-cooling water tank. The insulation sheath, freshly extruded and wrapped around the cable core, passes through the pre-cooling water tank. The spray water curtain assembly sprays water downwards, and the upward-lifting water curtain assembly sprays water upwards, allowing the water curtains at both ends to spray onto the surface of the cable insulation sheath. This achieves preliminary cooling and shaping of the cable insulation sheath without hard contact. A circulating water tank is installed at the lower end of the water-cooling sleeve, and a circulating water pump is installed inside the circulating water tank. The outlet end of the circulating water pump is connected to the lower end of the water-cooling sleeve. The cable, after preliminary cooling and shaping, passes through the water-cooling sleeve. The circulating water pump pumps cooling water from the circulating water tank into the water-cooling sleeve, ensuring that the cable insulation sheath in the water-cooling sleeve is fully cooled and shaped by the cooling water in the water-cooling sleeve.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 4 This utility model relates to a cable cooling device for a cable extruder, comprising a precooling component 1 and a water-cooling sleeve 2. The precooling component 1 includes a spray water curtain assembly 101, an upward water curtain assembly 102, and a precooling water tank 103. The precooling component 1 is positioned on one side of the water-cooling sleeve 2. The spray water curtain assembly 101 is positioned at the upper end of the precooling water tank 103 within the precooling component 1, and the upward water curtain assembly 102 is positioned at the bottom end of the precooling water tank 103. The insulation sheath, freshly extruded and wrapped around the cable core, passes through the precooling water tank 103, and is sprayed downwards by the spray water curtain assembly 101 and upwards by the upward water curtain assembly 102. A water curtain is sprayed from the top and bottom to spray water onto the surface of the cable insulation, achieving preliminary cooling and shaping of the cable insulation without hard contact. A circulating water tank 201 is set at the lower end of the water-cooled sleeve 2, and a circulating water pump 201a is set in the circulating water tank 201. The outlet end of the circulating water pump 201a is connected to the lower end of the water-cooled sleeve 2. The cable that has undergone preliminary cooling and shaping is passed through the water-cooled sleeve 2, and the circulating water pump 201a pumps the cooling water in the circulating water tank 201 into the water-cooled sleeve 2, which fully cools and shapes the cable insulation in the water-cooled sleeve 2.

[0027] Specifically, a circulating water tank 201 is provided at the lower end of the water-cooled jacket 2, and a circulating water pump 201a is provided in the circulating water tank 201. The outlet end of the circulating water pump 201a is connected to the lower side of the water-cooled jacket 2. A pre-cooling water tank 103 is provided on the upper side of the end of the circulating water tank 201 near the end face of the water-cooled jacket 2. A pipe is connected to one side of the pre-cooling water tank 103 and the pipe extends into the circulating water tank 201. A spray water curtain assembly 101 is provided at the upper end of the pre-cooling water tank 103, and an upward water curtain assembly 102 is provided at the bottom end of the pre-cooling water tank 103.

[0028] Furthermore, cable openings 103a are respectively provided on both sides of the precooling water tank 103, and a receiving roller 103b is rotatably installed between the two sides of the end of the precooling water tank 103 near the water cooling sleeve 2.

[0029] Furthermore, the upper end of the receiving roller 103b in the precooling water tank 103 is higher than the lower end of the cable opening 103a, so that the cable is placed on the upper end of the receiving roller 103b, thus preventing the inner wall of the cable opening 103a from scratching the insulation of the cable.

[0030] Furthermore, the spray water curtain assembly 101 includes an inclined plate sleeve 101a, a set of water curtain plates 101b, and an upper water pipe 101c. The lower end of the inclined plate sleeve 101a is fixedly sleeved at the upper opening of the precooling water tank 103. The inclined plate sleeve 101a has openings at both the upper and lower ends. The water curtain plates 101b are arranged in an array and fixedly installed inside the inclined plate sleeve 101a along its length. The upper end of the water curtain plates 101b is perpendicular to the lower end and inclined to one side. There are gaps between the water curtain plates 101b inside the inclined plate sleeve 101a. A set of nozzle sleeves 101a-1 is provided at the upper end of the inclined plate sleeve 101a. Each nozzle sleeve 101a-1... 1. A nozzle is fixedly fitted inside the nozzle sleeve 101a-1 in the gap between each water curtain plate 101b. The nozzle outlet end of each nozzle in the nozzle sleeve 101a-1 is vertically downward. The upper end of each nozzle in the nozzle sleeve 101a-1 is connected to an upper water pipe 101c. One end of the upper water pipe 101c is connected to the outlet end of the circulating water pump 201a. A set of nozzles at the lower end of the upper water pipe 101c sprays water jets downward. After the water jets come into contact with the water curtain plate 101b, they form a surface water curtain and flow downward. The downward flowing water curtain sprays onto the upper end of the insulation of the cable, cooling the upper end of the cable insulation.

[0031] Furthermore, the upward water curtain assembly 102 includes a set of upward nozzle sleeves 102a and a lower water pipe 102b. The upward nozzle sleeve 102a is a square tube sleeve structure with an opening vertically upward. One side of the upward nozzle sleeve 102a is connected to a nozzle, and the outlet end of the nozzle extends horizontally into the interior of the upward nozzle sleeve 102a. The nozzles on the sides of each upward nozzle sleeve 102a are connected to the lower water pipe 102b. One end of the lower water pipe 102b is connected to the outlet end of the circulating water pump 201a. A set of nozzles connected to the lower water pipe 102b sprays water jets onto the inner wall of the upward nozzle sleeve 102a. After the water jets come into contact with the inner wall of the upward nozzle sleeve 102a, they form a water curtain and spray upward, finally spraying onto the lower end of the cable insulation to cool the lower end of the cable insulation.

[0032] The operation process in this embodiment is as follows:

[0033] The insulation sheath, freshly extruded and wrapped around the cable core, is passed through the pre-cooling water tank 103. The cable is then placed on the upper end of the receiving roller 103b to prevent the inner wall of the cable opening 103a from scratching the outer insulation sheath. One end of the upper water pipe 101c is connected to the outlet of the circulating water pump 201a. A set of nozzles at the lower end of the upper water pipe 101c sprays water jets downwards. After the water jets contact the water curtain plate 101b, they form a surface-shaped water curtain and flow downwards, spraying water onto the cable. The upper end of the cable insulation is cooled. A set of nozzles connected to the lower water pipe 102b sprays water jets onto the inner wall of the upward-facing nozzle sleeve 102a. After the water jets come into contact with the inner wall of the upward-facing nozzle sleeve 102a, they form a water curtain and spray upwards, finally spraying onto the lower end of the cable insulation to cool it. The pre-cooled cable insulation rests on the receiving roller 103b and is less prone to deformation when it is rolled and conveyed on the receiving roller 103b.

[0034] Example 2

[0035] Please see Figures 1 to 5 Based on embodiment 1, pipe end sleeves 202 are fixedly sleeved at both ends of the water-cooled sleeve 2. A receiving roller seat 103c is provided on the outer side of the pipe end sleeve 202 near the pre-cooling water tank 103. A receiving roller 103b is rotatably installed inside the receiving roller seat 103c. By placing the cable pulled out from the pre-cooling component 1 on the receiving roller 103b on the receiving roller seat 103c, the outer insulation of the cable rolls and rubs against the receiving roller 103b when the cable is conveyed into the water-cooled sleeve 2, thus preventing the inner wall of the pipe end sleeve 202 from scratching the outer insulation of the cable.

[0036] Specifically, pipe end sleeves 202 are fixedly sleeved at both ends of the water-cooled sleeve 2, and cable sleeves 202a are connected to the side of the pipe end sleeves 202.

[0037] Furthermore, a receiving roller seat 103c is fixedly installed on the outside of the pipe end sleeve 202 near the precooling water tank 103 of the water-cooled jacket 2. A receiving roller 103b is rotatably installed inside the receiving roller seat 103c. The roller axis of the receiving roller 103b inside the receiving roller seat 103c is at the same horizontal height as the roller axis of the receiving roller inside the precooling water tank 103.

[0038] The operation process in this embodiment is as follows:

[0039] The cable, which has been pre-cooled by the pre-cooling component 1, is pulled out and placed on the receiving roller 103b on the receiving roller seat 103c. This allows the outer insulation of the cable to roll and rub against the receiving roller 103b as it is conveyed into the water-cooled sleeve 2, preventing the inner wall of the tube end sleeve 202 from scratching the outer insulation of the cable. The circulating water pump 201a pumps the cooling water in the circulating water tank 201 into the water-cooled sleeve 2, which fully cools and shapes the cable insulation in the water-cooled sleeve 2.
