Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, specifically to a cooling device and method for producing wires and cables. Background Technology

[0002] Cooling devices in wire and cable production are specialized equipment used in the cable manufacturing process to rapidly and uniformly cool cables that have just completed high-temperature processing steps such as extrusion and vulcanization. Their core function is to promote the rapid solidification and molding of the cable's insulation and sheath layers, thereby ensuring that the product's dimensional accuracy, mechanical properties, and electrical performance meet relevant standards. However, traditional spray cooling devices in wire and cable production have significant functional limitations. Their design is relatively fixed: they are arranged in a straight line along the cable production line, and the water spray direction is fixed (e.g., single-sided spraying or top-and-bottom spraying). This design results in the water flow not fully covering the entire circumference of the cable, leading to insufficient cooling of the back surface and uneven cooling of different parts of the cable.

[0003] Furthermore, when drying cables after water cooling, existing technologies typically employ a rubber scraper to remove water. However, this method has significant drawbacks: since cable production often requires switching between products with different wire diameters, a scraper with a fixed aperture either cannot completely remove water due to excessively large gaps, or its aperture is too small, causing forced compression of the cable and resulting in problems such as insulation wear and core deformation.

[0004] Therefore, a cooling device and method for wire and cable production are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling device and method for the production of wires and cables to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device and method for wire and cable production, comprising a working platform, a traction machine and a winding machine arranged on the working platform, a cable connected between the traction machine and the winding machine, a cooling and drying assembly arranged on the working platform, the cooling and drying assembly comprising multiple support rods, the multiple support rods being fixedly connected to the working platform in a linear array, a water pipe being fixedly connected to the top of each support rod, a solenoid valve being fixedly connected to the bottom of each water pipe, an outer shell being fixedly connected to the bottom of each solenoid valve, an inner shell being rotatably connected to each outer shell, multiple water holes being opened on each inner shell, and multiple sliding blocks being fixedly connected to the inner ring surface of each inner shell, with a nozzle being snapped onto each sliding block.

[0007] Furthermore, each inner shell has multiple connecting plates fixedly connected in a ring array on its side wall. The ends of the multiple connecting plates on the same inner shell that are away from the inner shell are fixedly connected to a ring. Each water pipe has a small motor fixedly connected to its bottom side near the ring. The small motor has a fixed end and an output shaft. The output shaft of the small motor faces the ring. The output shaft of the small motor and the ring are connected by a synchronous belt through a pulley drive.

[0008] Furthermore, the cooling and drying assembly also includes a second support rod, which is fixedly connected to the working platform. An outer ring shell is fixedly connected to the top of the second support rod, and a miniature air pump is fixedly connected to the top of the outer ring shell. An inner ring shell is inserted inside the outer ring shell, and an air hole is opened at the top of the inner ring shell. A rubber belt is fixedly connected to the inner ring surface of the inner ring shell, and multiple rubber ring strips are fixedly connected to the inner ring surface of the rubber belt in a linear array. Two insert rods are symmetrically fixedly connected to the outer wall of the inner ring shell, and two slot blocks are symmetrically fixedly connected to the outer wall of the outer ring shell.

[0009] Furthermore, multiple support rods are arranged equidistantly in a straight line along the horizontal direction of the cable. The top of the water pipe is connected to a water supply device. The solenoid valve is electrically connected to a remote control. The outer shell and inner shell are both fitted onto the cable, and the outer shell, inner shell, and cable are set at the same center. A circular cavity is formed between the outer shell and inner shell. This cavity is connected to the water pipe externally through the solenoid valve and to the nozzle internally through a water hole.

[0010] Furthermore, the number of water holes, sliding blocks, and nozzles on a single inner casing is equal, and the side of the sliding block away from the ring is set as an opening. A small motor is electrically connected to a remote control.

[0011] Furthermore, the outer ring shell, inner ring shell, rubber strip, and multiple rubber rings are all sleeved on the cable, and the outer ring shell, inner ring shell, rubber strip, and multiple rubber rings are concentric with the cable. The miniature air pump is electrically connected to a remote control, with the air outlet of the miniature air pump facing downwards. The inner ring shell and outer ring shell fit tightly together, and both the inner and outer ring shells are made of metal. The inner ring shell and rubber strip constitute a complete airbag function, and the expansion and contraction of the airbag are controlled by the miniature air pump. The two plug rods and two slot blocks are all plugged in and adapted.

[0012] A cooling method for wire and cable manufacturing includes the following steps:

[0013] Step 1: Equipment preset and preparation: Attach the appropriate nozzle along the opening of the slide block, ensuring that the nozzle is aligned and connected with the water hole.

[0014] Step 2: Start the cooling spray system: When the cable moves from the traction machine to the winding machine and passes through multiple inner shells, the solenoid valve and small motor are started by remote control. Water in the water pipe flows into the cavity between the outer shell and the inner shell through the solenoid valve, and then enters the nozzle through the water hole, and is sprayed onto the cable by the nozzle. The small motor drives the inner shell and the nozzle to rotate around the cable through the synchronous belt, realizing full-circumference dynamic flushing.

[0015] Step 3: Adjust the drying and scraping device: After the cable has been cooled, the controller operates the micro air pump to blow air downwards, causing the rubber strip of the inner ring shell to expand and drive the rubber ring to contact and adhere to the surface of the cable. This state is fixed to ensure that the moisture is scraped off, so that the cable remains dry when it moves to the winding machine side.

[0016] Step 4: Adaptation and Replacement Operation: According to the cable specifications, different types of nozzles can be replaced by inserting and unplugging along the slide block; when the rubber belt or rubber ring is worn out, the inner ring shell can be replaced by inserting and unplugging the plug rod and the slot block to achieve quick replacement of related parts.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In existing technologies, the fixed direction of the nozzles (single-sided or top-to-bottom spraying) prevents the water flow from covering the entire circumference of the cable, resulting in delayed cooling on the back side. However, with the operation of the cooling and drying components, the nozzles are evenly distributed on the inner surface of the inner casing, allowing water to be sprayed from the entire circumference of the cable. Combined with the rotation of the inner casing, the water flow dynamically washes every area of ​​the cable surface, completely eliminating the back side and cooling blind spots, ensuring that the cooling rate of all parts of the cable is consistent, and solving the problem of uneven cooling.

[0019] Meanwhile, the operation of the cooling and drying components and the detachable design of the nozzles make it easy to replace nozzles with different spray patterns (such as adjusting water spray density and impact force) according to cable specifications (such as diameter and surface characteristics). Furthermore, it allows for quick replacement of worn or clogged nozzles during routine maintenance without disassembling the entire water spray system, reducing downtime for maintenance.

[0020] In existing technologies, rubber plate squeegee devices have fixed apertures, which cannot adapt to cables of different diameters. This results in either excessively large gaps leading to incomplete squeegeeing or excessively small gaps causing damage to the cable. However, by operating the cooling and drying components, the fit between the rubber ring and the cable surface can be flexibly adjusted according to the cable thickness, achieving flexible adjustment for cable diameter. At the same time, it ensures the dryness of the cable, preventing moisture residue due to insufficient pressure and avoiding wear of the cable insulation layer and deformation of the core due to excessive pressure.

[0021] Meanwhile, the detachable design of the rubber belt and rubber rings makes it easy to replace parts individually when they wear out or age, reducing maintenance costs. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0034] The embodiments provided by this invention:

[0035] Example 1: Please refer to Figures 1 to 9 As shown, a cooling device and method for producing wires and cables includes a working platform 11, on which a traction machine 12 and a winding machine 13 are arranged, and a cable 14 is connected between the traction machine 12 and the winding machine 13.

[0036] The following components are known technologies: the working platform 11, the traction machine 12, the winding machine 13, and the cable 14. The traction machine 12 includes a drive component, a traction wheel, and a clamping component. The drive component provides power, and the traction wheel moves the cable 14 through friction. The clamping component is used to fix the cable 14 and prevent it from slipping during traction. The winding machine 13 includes a winding shaft, a winding wheel, and a drive motor. The winding shaft supports the winding wheel, and the drive motor provides power to rotate the winding wheel, thereby achieving the winding of the cable 14.

[0037] As a supplement to the previous one: the combined operation of the traction machine 12 and the winding machine 13 can realize the movement of the cable 14. The side of the traction machine 12 away from the winding machine 13 is the high-temperature processing end of the cable 14, and the side of the winding machine 13 is the cooling and drying winding end of the cable 14.

[0038] A cooling and drying assembly is installed on the working platform 11. The cooling and drying assembly includes multiple support rods 21, which are fixedly connected to the working platform 11 in a linear array. A water pipe 23 is fixedly connected to the top of each support rod 21, and a solenoid valve 25 is fixedly connected to the bottom of each water pipe 23. An outer shell 26 is fixedly connected to the bottom of each solenoid valve 25, and an inner shell 27 is rotatably connected to each outer shell 26. Multiple water holes 28 are opened on each inner shell 27, and multiple sliding blocks 29 are fixedly connected to the inner ring surface of each inner shell 27. A nozzle 210 is snapped onto block 29. Multiple connecting plates 211 are fixedly connected in a ring array on the side wall of each inner shell 27. The ends of the multiple connecting plates 211 on the same inner shell 27 away from the inner shell 27 are fixedly connected to a ring 212. A small motor 213 is fixedly connected to the bottom of each water pipe 23 near the ring 212. The small motor 213 is divided into a fixed end and an output shaft. The output shaft end of the small motor 213 faces the ring 212. The output shaft of the small motor 213 and the ring 212 are connected by a synchronous belt 214 through a pulley drive.

[0039] Where: Reference Figure 1 As shown, multiple support rods 21 are arranged at equal intervals in a straight line along the horizontal direction of cable 14, referring to... Figure 2 As shown, the top of the water pipe 23 is connected to an external water supply device.

[0040] Where: Reference Figure 4As shown, the solenoid valve 25 is a known prior art technology. The solenoid valve 25 is electrically connected to a remote control. The solenoid valve 25 is used to control whether the water inside the water pipe 23 flows downward.

[0041] Where: Reference Figure 4 , Figure 7 , Figure 9 As shown, the outer shell 26 and the inner shell 27 are both fitted onto the cable 14, and the outer shell 26, the inner shell 27, and the cable 14 are arranged at the same center.

[0042] As a supplement to the previous one: an annular cavity is formed between the outer shell 26 and the inner shell 27. This cavity is connected to the water pipe 23 externally through the solenoid valve 25, and to the nozzle 210 internally through the water hole 28. That is, the user can supply water to the nozzle 210 by controlling the solenoid valve 25.

[0043] Where: Reference Figure 4 , Figure 9 As shown, the number of water holes 28, sliding blocks 29 and nozzles 210 on a single inner sleeve 27 are equal. The side of the sliding block 29 away from the ring 212 is set as an opening. The user can snap the nozzle 210 onto the sliding block 29 along the opening of the sliding block 29. When the nozzle 210 is snapped onto the sliding block 29, the nozzle 210 and the water hole 28 are aligned and connected. The end of the nozzle 210 away from the sliding block 29 is the water spray hole.

[0044] As a supplement to the previous point: the insertion point between the nozzle 210 and the slide block 29 is set in a T-shape. After insertion, it slides horizontally a certain distance to be inserted tightly and aligned. This prevents the impact force of the water flow from knocking the nozzle 210 open. Users can quickly replace the nozzle 210 by inserting and removing it from the slide block 29. In this way, users can replace different types of nozzles 210, such as fan-shaped nozzles, ring nozzles, slit nozzles, etc. They can also quickly replace the nozzle 210 when it is clogged or aged, so as to achieve uniformity and continuity of the cooling operation of the cable 14.

[0045] Where: Reference Figure 4 , Figure 7 As shown, the small motor 213 is electrically connected to a remote control.

[0046] As a supplement to the previous one: the user can drive the output shaft of the small motor 213 to rotate via remote control. The output shaft of the small motor 213 drives the ring 212 to rotate synchronously via the synchronous belt 214. The ring 212 drives the inner shell 27 to rotate synchronously via multiple connecting plates 211. While the inner shell 27 rotates, it drives multiple nozzles 210 to rotate synchronously via multiple sliding blocks 29 on its inner ring surface. At this time, the inner shell 27 rotates on the outer shell 26, and the rotation of the inner shell 27 and the multiple nozzles 210 is centered on the cable 14, that is, the multiple nozzles 210 rotate around the cable 14.

[0047] In summary: When the cooling and drying assembly is in operation, and the cable 14 is being moved by the traction machine 12 and the winding machine 13, and cooling of the cable 14 is required, the operation of the cooling and drying assembly is as follows:

[0048] The user inserts the desired nozzle 210 into the slide block 29 beforehand.

[0049] When the cable 14 is moved by the traction machine 12 and the winding machine 13, the cable 14 moves from the traction machine 12 to the winding machine 13. During this process, the cable 14 passes through the inside of multiple inner shells 27. At this time, the user activates multiple solenoid valves 25 and multiple small motors 213 via remote control. As the solenoid valves 25 are activated, the water supplied by the water pipe 23 flows through the solenoid valves 25 into the cavity formed by the outer shell 26 and the inner shell 27, and enters the corresponding nozzles 210 through multiple water holes 28 in the cavity, and is sprayed onto the cable 14 by the multiple nozzles 210.

[0050] When the solenoid valve 25 is activated, the small motor 213 is also activated. The activation of the small motor 213 causes its output shaft to rotate. The output shaft of the small motor 213 drives the ring sleeve 212 to rotate synchronously through the synchronous belt 214. The ring sleeve 212 drives the inner shell 27 to rotate synchronously through multiple connecting plates 211. At the same time, the inner shell 27 rotates synchronously through multiple sliding blocks 29 on its inner ring surface, driving multiple nozzles 210 to rotate synchronously. At this time, the inner shell 27 rotates on the outer shell 26, and the rotation of the inner shell 27 and the multiple nozzles 210 is centered on the cable 14. That is, the multiple nozzles 210 rotate around the cable 14. In combination with the above, at this time, the multiple nozzles 210 rotate around the cable 14 while spraying, and the cable 14 is subjected to uniform spraying and rotational scouring around the entire circumference.

[0051] In summary, the operation of the cooling and drying components can produce the following beneficial effects:

[0052] In the prior art, because the nozzle 210 is fixed in one side or sprays water from top to bottom, the water flow cannot cover the outer surface of the cable 14, resulting in delayed cooling on the back side. However, through the operation of the cooling and drying component, the nozzles 210 are evenly distributed on the inner surface of the inner shell 27, which can spray water from the entire circumference of the cable 14. With the rotation of the inner shell 27, the water flow dynamically washes every area of ​​the surface of the cable 14, completely eliminating the back side and cooling blind spots, and ensuring that the cooling rate of each part of the cable 14 is consistent, thus solving the problem of uneven cooling.

[0053] Meanwhile, through the operation of the cooling and drying components, the detachable design of the nozzle 210 makes it easy to replace the nozzle 210 with different spray patterns according to the specifications of the cable 14, such as diameter and surface characteristics, to adjust the water spray density and impact force. Furthermore, it allows for quick replacement of worn or clogged nozzles 210 during routine maintenance without disassembling the entire water spray device, reducing downtime for maintenance.

[0054] The cooling and drying assembly also includes a second support rod 215, which is fixedly connected to the working platform 11. An outer ring shell 216 is fixedly connected to the top of the second support rod 215, and a micro air pump 217 is fixedly connected to the top of the outer ring shell 216. An inner ring shell 218 is inserted inside the outer ring shell 216. An air hole 219 is opened on the top of the inner ring shell 218. A rubber belt 220 is fixedly connected to the inner ring surface of the inner ring shell 218. Multiple rubber ring strips 221 are fixedly connected to the inner ring surface of the rubber belt 220 in a linear array. Two insert rods 22 are symmetrically fixedly connected to the outer wall of the inner ring shell 218, and two slot blocks 24 are symmetrically fixedly connected to the outer wall of the outer ring shell 216.

[0055] Where: Reference Figure 3 , Figures 6 to 8 As shown, the outer ring shell 216, the inner ring shell 218, the rubber strip 220, and the multiple rubber rings 221 are all sleeved on the cable 14, and the outer ring shell 216, the inner ring shell 218, the rubber strip 220, and the multiple rubber rings 221 are arranged concentrically with the cable 14.

[0056] Where: Reference Figure 7 , Figure 8 As shown, the miniature air pump 217 is electrically connected to a remote control. The air outlet of the miniature air pump 217 faces downward. The inner ring shell 218 and the outer ring shell 216 are tightly fitted together. When the inner ring shell 218 is inserted into the outer ring shell 216, the air outlet of the miniature air pump 217 is aligned and connected with the air hole 219. That is, at this time, the miniature air pump 217 can blow and suck air into the inner ring shell 218 through the inner ring shell 218.

[0057] As a supplement to the previous one: both the inner ring shell 218 and the outer ring shell 216 are made of metal. When the micro air pump 217 blows air into the inner ring shell 218, the rubber band 220 will expand inward accordingly. That is, the inner ring shell 218 and the rubber band 220 constitute a complete airbag function, and the expansion and contraction of the airbag are controlled by the micro air pump 217.

[0058] Where: Reference Figure 3 , Figures 6 to 8 As shown, both insert rods 22 are plugged into and matched with both slot blocks 24. The plugging function of the slot blocks 24 and the insert rods 22 is to facilitate the user to detach the inner ring shell 218 from the outer ring shell 216.

[0059] As a supplement to the previous one: the user can quickly replace the inner ring shell 218 by inserting and unplugging the plug 22 into the slot block 24. In this way, the user can quickly replace the rubber belt 220 and rubber ring 221 when they are worn out, so as to achieve uniformity and continuity of the drying operation of the cable 14.

[0060] In summary: When the cooling and drying assembly is in operation, and the cable 14 is being moved by the traction machine 12 and the winding machine 13, and the cable 14 has already undergone stepped cooling and needs to be dried, the operation of the cooling and drying assembly is as follows:

[0061] The user controls the micro air pump 217 to blow air downwards via the controller. The micro air pump 217 blows air, causing the rubber band 220 to expand inwards. As the rubber band 220 expands, the rubber rings 221 undergo corresponding elastic deformation. When the rubber band 220 expands to the point where multiple rubber rings 221 touch the cable 14, the user controls the micro air pump 217 to stop blowing air. At this point, the state of multiple rubber rings 221 touching the cable 14 is fixed.

[0062] As the cable 14 is moved by the traction machine 12 and the winding machine 13, the cable 14 moves toward the winding machine 13 while being in contact with and pressed against by multiple rubber rings 221. As a result, the water sprayed onto the cable 14 by the spray cooling is scraped off by the multiple rubber rings 221, so that the cable 14 that moves through the rubber belt 220 to the side of the rubber belt 220 near the winding machine 13 is in a dry state.

[0063] If the rubber rings 221 and rubber strips 220 show signs of wear or aging, the user can quickly replace the inner ring shell 218 by inserting and removing the plug 22 into the slot block 24, and replace the rubber strips 220 and multiple rubber rings 221 on the inner ring shell 218 as a whole, thereby achieving uniformity and continuity in the drying process of the cable 14.

[0064] In summary, the operation of the cooling and drying components can produce the following beneficial effects:

[0065] In the prior art, the rubber plate squeegee device has a fixed aperture, which cannot be adapted to cables 14 with different wire diameters. This results in either the gap being too large and the squeegee not being thorough, or the gap being too small and damaging the cable 14. However, by operating the cooling and drying component, the fit between the rubber ring 221 and the surface of the cable 14 can be flexibly adjusted according to the thickness of the cable 14. This achieves flexible adjustment for the wire diameter of the cable 14, while ensuring the dryness of the cable 14. It will not leave moisture residue due to insufficient pressure, nor will it cause wear of the cable 14 insulation layer or deformation of the wire core due to excessive pressure.

[0066] Meanwhile, the detachable design of the rubber belt 220 and rubber ring 221 makes it easy to replace the parts individually when they are worn or aged, thus reducing maintenance costs.

[0067] Example 2: A cooling method for wire and cable production, comprising the following steps:

[0068] Step 1: Equipment preset and preparation: Connect the appropriate nozzle 210 along the opening of the slide block 29, and ensure that the nozzle 210 is aligned and connected with the water hole 28.

[0069] Step 2: Start the cooling spray system: When the cable 14 moves from the traction machine 12 to the winding machine 13 and passes through multiple inner shells 27, the solenoid valve 25 and the small motor 213 are started by the remote control. The water in the water pipe 23 flows into the cavity between the outer shell 26 and the inner shell 27 through the solenoid valve 25, and then enters the nozzle 210 through the water hole 28, and is sprayed onto the cable 14 by the nozzle 210. The small motor 213 drives the inner shell 27 and the nozzle 210 to rotate around the cable 14 through the synchronous belt 214, so as to realize full-circumference dynamic flushing.

[0070] Step 3: Adjust the drying and scraping device: After the cable 14 has been cooled, the micro air pump 217 is controlled by the controller to blow air downwards, causing the rubber strip 220 of the inner ring shell 218 to expand, which drives the rubber ring 221 to contact and adhere to the surface of the cable 14. This state is fixed to ensure that the moisture is scraped off, so that the cable 14 remains dry when it moves to the side of the winding machine 13.

[0071] Step 4: Adaptation and Replacement Operation: According to the specifications of cable 14, different styles of nozzles 210 can be replaced by inserting and unplugging along the slide block 29; when the rubber belt 220 or rubber ring 221 is worn due to aging, the inner ring shell 218 can be replaced by inserting and unplugging the plug rod 22 and the slot block 24 to achieve quick replacement of related parts.
