Description

Technical Field

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

[0002] Cable production mainly includes conductor drawing, insulation / sheath extrusion, cabling, and armoring processes. Cooling is crucial, especially after extrusion where rapid cooling and shaping are necessary to prevent material deformation or performance degradation. Cooling prevents insulation softening at high temperatures, which can lead to eccentricity and uneven thickness. It also reduces conductor annealing, ensuring stable mechanical strength and electrical performance. Traditional cable cooling methods often involve using a cooling water bath with a cooling liquid. This method is inefficient and can allow moisture to remain on the cable surface, potentially entering the next process and affecting cable quality.

[0003] As shown in the reference case "A Cooling Device for Cable Production" announcement number "CN222775065U", through the setting of the cooling mechanism, during use, the drying component can evaporate the water absorbed by the absorbent pad by heating the drying plate, so that the absorbent pad remains dry, ensuring that the drying component can absorb the water on the surface of the cooled cable, and avoiding excessive water affecting subsequent processes. Although the above application can wipe the moisture on the cable surface by setting up an absorbent pad and continuously dry the absorbent pad by a drying component, thus keeping the absorbent pad continuously dry, the absorbent pad is prone to aging and hardening after being repeatedly soaked and dried. The hardened absorbent pad has a poor water absorption effect and is also prone to damaging the surface of the cable. Utility Model Content

[0004] Therefore, it is necessary to provide a cooling device for cable production to address the problem that absorbent pads tend to harden after repeated drying, resulting in poor water absorption.

[0005] A cooling device for cable production includes: a cooling tank and a collection component disposed at one end of the cooling tank; The cooling mechanism includes two mounting brackets installed above the cooling tank, and a water blowing assembly is disposed between the two mounting brackets.

[0006] In one embodiment, the water blowing assembly includes a retaining ring fixedly connected between two mounting brackets, and a plurality of high-pressure air nozzles are fixedly connected to the inner wall of the retaining ring.

[0007] In one embodiment, the plurality of high-pressure air nozzles are evenly distributed circumferentially on the inner wall of the fixed ring, and the inner wall of the fixed ring is provided with an air collecting pipe, which is annular and communicates with the plurality of high-pressure air nozzles.

[0008] In one embodiment, an air pump is fixedly connected to one side surface of the cooling tank, and the air outlet of the air pump is connected to the air collection pipe through an air pipe that passes through a fixing ring.

[0009] In one embodiment, a first adjusting roller and a second adjusting roller are respectively installed between the two mounting brackets. The first adjusting roller is rotatably connected to the mounting bracket surface on the side away from the collecting assembly and is positioned directly below the fixing ring.

[0010] In one embodiment, the second adjusting roller is rotatably connected to the mounting bracket surface near the collecting assembly, and the second adjusting roller is positioned directly above the fixing ring.

[0011] In one embodiment, two motorized roller brushes are disposed between the two mounting brackets, and the two motorized roller brushes are respectively mounted on the surfaces of the two mounting brackets. The motorized roller brushes are disposed between the fixing ring and the second adjusting roller.

[0012] In one embodiment, the cooling tank is rotatably connected to a plurality of limiting rollers, which are distributed in a “V” shape. Beneficial effects

[0013] By guiding the cooled cable vertically upwards and spraying high-speed airflow along its surface using multiple sets of high-pressure nozzles, a triple optimization effect can be achieved simultaneously: First, gravity allows the attached water film to flow down naturally, significantly reducing the amount of residual water; second, the high-pressure airflow directly peels off and blows away residual droplets on the surface, achieving non-contact and efficient drying; and third, the evaporation and heat absorption of the airflow further enhances the cooling effect, avoiding insulation layer damage caused by traditional wiping, while reducing energy consumption and coolant loss, significantly improving the reliability and production efficiency of subsequent processes. By setting multiple "V"-shaped distribution limit rollers inside the cooling tank, the friction loss caused by the cable entering and exiting the cooling tank is reduced, and the cable can be fully contacted with the coolant to improve the cooling effect.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes a cooling device for cable production.

[0019] In one embodiment, a cooling device for cable production includes: a cooling tank 100 and a collection assembly 200 disposed at one end of the cooling tank 100; The cooling mechanism 300 includes two mounting brackets 310 mounted above the cooling tank 100, and a water blowing assembly 320 is disposed between the two mounting brackets 310.

[0020] In this device, the collecting component 200 consists of a take-up roller and two support frames for supporting the take-up roller. The two support frames are respectively set on both sides of the take-up roller, and both ends of the take-up roller are rotatably connected to the support frames. A servo motor is mounted on the surface of one of the support frames. The drive end of the servo motor is fixedly connected to one end of the take-up roller through a coupling. Therefore, the take-up roller is driven by the servo motor. The highest point of the take-up roller is flush with the highest point of the second adjusting roller 312. The cable is wound around the surface of the take-up roller by the rotation of the take-up roller.

[0021] like Figure 3 , Figure 4 and Figure 5As shown, the water blowing assembly 320 includes a fixing ring 321 fixedly connected between two mounting brackets 310. Multiple high-pressure air nozzles 323 are fixedly connected to the inner wall of the fixing ring 321. The multiple high-pressure air nozzles 323 are evenly distributed circumferentially on the inner wall of the fixing ring 321. An air collecting pipe 322 is provided on the inner wall of the fixing ring 321, and the air collecting pipe 322 is annular and communicates with the multiple high-pressure air nozzles 323. An air pump 324 is fixedly connected to one side surface of the cooling tank 100. The air outlet of the air pump 324 passes through an air pipe into the fixing ring 321 and communicates with the air collecting pipe 322. A first adjusting roller 311 and a second adjusting roller 312 are respectively installed between the two mounting brackets 310. The first adjusting roller 311 is rotatably connected to the surface of the mounting bracket 310 on the side away from the collecting assembly 200, and the first adjusting roller 311 is located directly below the fixing ring 321. The second adjusting roller 312 is rotatably connected to the surface of the mounting bracket 310 near the side of the collecting assembly 200, and the second adjusting roller 312 is positioned directly above the fixing ring 321.

[0022] In this embodiment, the air pump 324 drives a turbine to operate at high speed via a motor, generating a high-pressure airflow. This airflow is then delivered to the high-pressure nozzle 323 via a pressure-stabilizing air pipe. The nozzle employs a Venturi tube structure design to accelerate the airflow, forming a high-speed jet. Multiple high-pressure nozzles 323 thoroughly blow air onto the surface of the cable. After the extrusion process, the cable enters the cooling tank 100 above the limiting roller 330 at the end furthest from the mounting frame 310. After entering the cooling tank 100, the cable passes under the multiple limiting rollers 330 in a "V" shape, where it is cooled. After passing the limiting roller 330 near one end of the mounting bracket 310, the cable is guided vertically upward, passing in sequence through the surface of the first adjusting roller 311, the center of the fixing ring 321, the two electric rollers 313, and the second adjusting roller 312. After passing the second adjusting roller 312, the cable bends at a 90-degree angle toward the take-up roller and is fixed to the surface of the take-up roller. The cable is then wound around the surface of the take-up roller by the rotation of the take-up roller. The surfaces of the two electric rollers 313 are provided with soft bristles made of polyester material, which can effectively remove moisture and avoid scratching the cable insulation layer. It should be noted that this device optimizes the traditional method of wiping the surface of the cable to remove water by using gravity and blowing. Since the cooling mechanism 300 of this device is mostly located on the upper surface of the cooling tank 100, it will not affect the normal cooling of the cable. At the same time, this device only cools the cable and removes water after cooling, and will not affect other processes of the cable. Therefore, the cooling mechanism 300 of this device will not have any impact on the normal process and cooling of the cable.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, two electric roller brushes 313 are arranged between the two mounting brackets 310. The two electric roller brushes 313 are respectively mounted on the surfaces of the two mounting brackets 310 and are located between the fixing ring 321 and the second adjusting roller 312. Multiple limiting rollers 330 are rotatably connected inside the cooling tank 100, and the multiple limiting rollers 330 are distributed in a "V" shape.

[0024] In this embodiment, multiple limiting rollers 330 are all located at the center line of the cooling tank 100. The limiting rollers 330 located inside the cooling tank 100 are rotatably connected to the fixed columns on both sides of the inner wall of the cooling tank 100, while the limiting rollers 330 located at the entrance of the cooling tank 100 are directly rotatably connected to the inner wall of the cooling tank 100. At the same time, "L"-shaped limiting blocks are provided on both sides of the two adjusting rollers, and both ends of the adjusting rollers are rotatably connected to the limiting blocks. The two "L"-shaped limiting blocks are fixedly connected to the lower surface of the crossbar of the mounting frame 310. The electric roller brush 313 is mainly composed of a drive motor, a rotating shaft, a flexible coupling, a polyester fiber bristle layer, and a waterproof shell. Its working principle is as follows: the drive motor drives the shaft to rotate at high speed through the coupling, so that the radially distributed bristles generate centrifugal force and contact the cable surface. The elastic deformation of the fibers forms micro-friction, which simultaneously achieves water removal and surface polishing.

[0025] Working principle: The cable that has undergone the extrusion process is introduced into the cooling tank 100 through multiple limiting rollers 330. The cable passes under all the limiting rollers 330. After the cable passes the limiting roller 330 near the end of the water blowing assembly 320, the cable is guided vertically upward. Under the adjustment of the two adjusting rollers, the cable passes through the fixing ring 321 and is wound up by the collecting assembly 200. As the cable moves vertically upward, most of the coolant on its surface will fall back into the cooling tank 100 under the action of gravity. When the cable passes the fixing ring 321, multiple high-pressure air nozzles 323 in the fixing ring 321 will blow air onto the surface of the cable, blowing away the water adhering to the surface of the cable through the high-pressure airflow, causing the water to flow downward along the surface of the cable and fall back into the cooling tank 100 under the action of gravity. After being blown by the water, the cable will pass through two electric roller brushes 313. The electric roller brushes 313 will wipe the surface of the cable while rotating, performing the final cleaning of the cable surface. After being cleaned, the cable will be wound up and collected by the collecting component 200.

[0026] It should be noted that the high-pressure air nozzle 323, air pump 324, electric roller brush 313, and collection component 200 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the air pump 324, electric roller brush 313, and collection component 200 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
