Description

Technical Field

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

[0002] The field of wire and cable manufacturing technology mainly studies the basic knowledge and skills of wire and cable manufacturing processes, cable structure, cable machinery, and cable testing technology. In the field of wire and cable manufacturing technology, it involves the control of wire and cable production equipment, the preparation and implementation of production processes, product quality inspection and control, and production management. Stranded wire is a link in the production of wires and cables. Stranded wire is achieved by twisting single wires around the stranding axis at a constant angular velocity and by the stranded wire moving forward at a constant speed. The two most commonly used wires are copper and aluminum. Copper and aluminum wires can be stranded into conductors of various specifications and cross-sections and different types of wires and cables.

[0003] In existing technologies, stranding equipment is often used in the production of wires and cables. Common stranding equipment involves placing the female and male wires of the wire and cable separately, and then rotating the stranding reel to wind the female wire around the male wire, thereby improving its flexibility and mechanical strength. However, during the stranding process, the male and female wires are usually exposed to the outside environment. Consequently, dust and foreign objects from the outside air become trapped inside the stranded wires, affecting their reliability. Therefore, it is necessary to clean the dust and foreign objects during the stranding process. Existing cleaning methods typically involve washing and drying, which exposes the surfaces of the female and male wires to a significant temperature difference. This affects the resistance of the female and male wires, thus impacting their subsequent performance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a stranding device for producing wires and cables, thereby solving the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A stranding device for producing wires and cables includes a workbench, a PLC controller fixedly installed on one side of the workbench, and a cleaning seat fixedly installed on the top surface of the workbench.

[0007] The outer circular wall of the cleaning seat is rotatably connected to several lower cleaning sleeves, and the top surface of the lower cleaning sleeves is rotatably connected to an upper cleaning sleeve. A first semiconductor heating element is fixedly installed on one side of the upper cleaning sleeve and one side of the lower cleaning sleeve. A water storage pipe is fixedly installed on one side of the cleaning seat, and several water mist nozzles are fixedly sleeved on the inner circular wall of the water storage pipe. The water mist nozzles correspond to the positions of the lower cleaning sleeves.

[0008] A first sliding sleeve slides on one side of the inner side of the cleaning seat. A first temperature sensor is fixedly sleeved on the inner circular wall of the first sliding sleeve. The first temperature sensor is electrically connected to the water tank. An arc-shaped probe is fixedly installed at one end of the probe rod of the first temperature sensor. A second sliding sleeve slides on one side of the inner side of the cleaning seat. A limit plate is fixedly installed on one side of the second sliding sleeve. Two threaded positioning blocks are fixedly installed on one side of the cleaning seat. A first threaded rod is rotatably connected to one side of both the first and second sliding sleeves. The first threaded rod is threadedly connected to the inner circular wall of the threaded positioning block.

[0009] The inner circular wall of the cleaning seat is provided with two busbar cleaning covers. A second threaded rod is fixedly installed on one side of the busbar cleaning cover and is threadedly connected to the cleaning seat. Two guide rods are fixedly installed on the outer circular wall of the busbar cleaning cover and are slidably connected to the cleaning seat. A second semiconductor heating element is fixedly installed inside the busbar cleaning cover. Both the second semiconductor heating element and the first semiconductor heating element are electrically connected to the PLC controller.

[0010] By adopting the above technical solution, during the stranding process, the sub-wires of the electric wire and cable are passed between multiple lower and upper cleaning sleeves, and then the lower and upper cleaning sleeves are connected and fixed with bolts. The busbar of the electric wire and cable is then passed between two busbar cleaning covers. Next, by rotating the two first threaded rods, the first and second sliding sleeves simultaneously approach the busbar of the electric wire and cable. At this time, the arc-shaped probe at one end of the first temperature sensor's detection rod will be in contact with the surface of the busbar, while the limiting plate provides auxiliary support on the other side of the busbar. Then, by rotating the two second threaded rods, the two busbar cleaning covers are made to fit against the outer wall of the busbar. After the above steps are completed, the busbar and sub-wires can be stranded. The first temperature sensor will then monitor the external temperature of the busbar in real time and... The data is fed back to the PLC controller, which then activates the first and second semiconductor heating elements. These elements heat the lower cleaning sleeve, upper cleaning sleeve, and busbar cleaning cover, respectively. This ensures that the lower cleaning sleeve, upper cleaning sleeve, and busbar cleaning cover maintain the same temperature as the busbars and sub-wires during cleaning. Simultaneously, the PLC controller controls the water temperature inside the tank, ensuring that the water mist from the multiple nozzles is close to the temperature of the busbars and sub-wires. This achieves the effect of cleaning the cables during twisting while maintaining a consistent cleaning temperature with the cable temperature, preventing damage to the cable's resistance due to temperature differences.

[0011] Preferably, a mounting frame is fixedly installed inside the workbench, and hot air boxes are fixedly installed on the top and bottom surfaces of the mounting frame. A second temperature sensor is fixedly installed on one side of the inside of the mounting frame, and both the hot air box and the second temperature sensor are electrically connected to the PLC controller.

[0012] By adopting the above technical solution, two hot air boxes with a second temperature sensor can detect the airflow temperature of the hot air box, and the temperature of the hot air box can be controlled by a PLC controller. Thus, the hot air box can dry the sub-wires and busbars of the wires and cables at the same temperature.

[0013] Preferably, a threaded post is fixedly installed on the bottom surface of the lower cleaning sleeve, a tensioning frame is fixedly installed on one side of the lower cleaning sleeve, a first guide wheel is rotatably connected inside the tensioning frame, and a plurality of threaded adjusting caps are rotatably connected to the outer circular wall of the cleaning seat, and the inner circular wall of the threaded adjusting caps is threadedly connected to the threaded post.

[0014] By adopting the above technical solution, the threaded column is moved out of the threaded adjusting cap by rotating the threaded adjusting cap, thereby causing the lower cleaning sleeve and the upper cleaning sleeve to rotate and their operating angles are adjusted. At the same time, the first guide wheel can guide the sub-line when it is being laid out, so that the operating angles of the lower cleaning sleeve and the upper cleaning sleeve can be adjusted to adapt to sub-lines of different thicknesses and tensions.

[0015] Preferably, a water tank is fixedly installed inside the workbench, a submersible pump is fixedly installed on the bottom surface of the water tank, a heating rod is fixedly installed on one side of the water tank, the submersible pump and the heating rod are both electrically connected to the PLC controller, and the inner circular wall of the submersible pump outlet is fixedly sleeved with the water storage pipe.

[0016] By adopting the above technical solution, the heating rod can be controlled by the PLC controller to heat the water inside the water tank to a temperature suitable for the sub-line and busbar. The hot water is then output to the inside of the water storage pipe by the submersible pump and sprayed onto the outside of the sub-line and busbar through the water mist nozzle to humidify and clean them.

[0017] Preferably, a stranded wire holder is fixedly installed on the top surface of the workbench, a protective cover is fixedly installed on one side of the stranded wire holder, a first drive motor is fixedly installed on the outer circular wall of the protective cover, the first drive motor is electrically connected to the PLC controller, a gear is fixedly installed on the bottom surface of the drive shaft of the first drive motor, a hollow shaft is rotatably connected to one side of the stranded wire holder, a gear plate is fixedly sleeved on the outer circular wall of the hollow shaft, the gear plate and the gear are meshed, a guide plate is fixedly sleeved on the outer circular wall of the hollow shaft, a plurality of second guide wheels are rotatably connected inside the guide plate, a limit plate is fixedly sleeved on the outer circular wall of the hollow shaft, and a plurality of limit holes are opened on one side of the limit plate.

[0018] By adopting the above technical solution, the busbar extends from the inside of the hollow shaft, and multiple sub-wires extend through the round holes on the side of the stranded wire holder. The sub-wires are then placed on the surfaces of multiple second guide wheels, which guide them. The sub-wires are then passed through multiple limiting holes. At this point, the first drive motor can be started by the PLC controller, causing the drive shaft of the first drive motor to drive the gear to rotate. Under the meshing transmission of the gear and the gear plate, the hollow shaft will drive the guide plate and the limiting plate to rotate, which will cause multiple sub-wires to rotate simultaneously. This facilitates the rotation and twisting of the multiple sub-wires, allowing them to be stranded on the outer wall of the busbar.

[0019] Preferably, a guide seat is fixedly installed on the top surface of the workbench. A plurality of threaded fastening sleeves are fixedly installed on one side of the guide seat. One end of each threaded fastening sleeve is tapered, and the outer circular wall of the threaded fastening sleeve is threaded. An adjusting cap is threadedly connected to the outer circular wall of the threaded fastening sleeve, and the inner wall of the adjusting cap is tapered. A plurality of rotating disks are rotatably connected to the other side of the guide seat. The rotating disks correspond to the positions of the threaded fastening sleeves. Two limiting seats are fixedly installed on one side of each rotating disk, and the two limiting seats are spaced apart. A mounting shell is slidably connected inside each limiting seat. Two pressure rollers are rotatably connected inside the mounting shell. A first mounting cylinder is fixedly sleeved on the inner circular wall of the limiting seat. A first spring is movably sleeved inside the first mounting cylinder. A first connecting post is slidably connected inside the first mounting cylinder, and the bottom surface of the first connecting post is fixedly installed to the mounting shell.

[0020] By adopting the above technical solution, multiple strands of sub-wires and busbars are passed through the interior of multiple threaded fastening sleeves. The adjustable cap can be rotated to make the threaded fastening sleeves made of spring steel retract inward, thereby limiting the sub-wires and busbars during the release of the wires. Then, the rebound force of multiple first springs causes multiple pressure rollers to squeeze the sub-wires and busbars, which can guide them and prevent them from becoming tangled as the sub-wires and busbars are continuously released.

[0021] Preferably, a parallel connector is fixedly installed on the top surface of the workbench. The parallel connector has several pressure plates inside. An adjusting rod is fixedly installed on one end of each pressure plate. A twisting groove is formed on the bottom surface of the pressure plate. The twisting groove is arc-shaped. An adjusting cover is threaded to one side of the parallel connector. The inner side of the adjusting cover is inclined. Several second mounting cylinders are fixedly installed on the inner circular wall of the parallel connector. Every two second mounting cylinders and one pressure plate form a group. A second connecting column is slidably connected inside the second mounting cylinder. A second spring is movably sleeved on the outer circular wall of the second connecting column. The bottom surface of the second connecting column is fixedly installed with the pressure plate.

[0022] By adopting the above technical solution, the busbar passes through the interior of the parallel connector and the adjusting cover. Then, the adjustable cover can be rotated so that its inner wall is pressed against multiple adjusting rods. In turn, the multiple adjusting rods drive multiple pressure plates to converge into the interior of the parallel connector. Then, the twisting groove at the bottom of the pressure plate will press down on the sub-wire so that it fits against the outside of the busbar. This fixes the position of the sub-wire and the busbar and prevents the sub-wire and the busbar from loosening due to internal stress after twisting.

[0023] Preferably, a plurality of positioning sleeves are fixedly installed on the top surface of the workbench. The inner circular wall of the positioning sleeve is threaded, and a wire feeding wheel is rotatably connected to the outer circular wall of the positioning sleeve. A fixing cap is connected to the internal thread of the positioning sleeve. A mounting frame is fixedly installed on the top surface of the workbench. A wire take-up wheel is rotatably connected to the inside of the mounting frame. A second drive motor is fixedly installed on one side of the mounting frame. The second drive motor is electrically connected to the PLC controller, and one end of the drive shaft of the second drive motor is fixedly installed to the wire take-up wheel.

[0024] By adopting the above technical solution, multiple pay-off reels can be used to place the sub-wires and main wires of the wire to be twisted. Then, the fixed cap can be rotated to release the limit on the pay-off reels and remove them from the top of the workbench. At the same time, the second drive motor drives the take-up reel to rotate and wind up the twisted wire and cable.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] 1. This invention uses a first temperature sensor to monitor the external temperature of the busbar in real time. At this time, the first and second semiconductor heating elements heat the lower cleaning sleeve, the upper cleaning sleeve, and the busbar cleaning cover, respectively. This ensures that when the lower cleaning sleeve, the upper cleaning sleeve, and the busbar cleaning cover clean the busbar and sub-wires of the cable, they maintain the same temperature as the sub-wires and the busbar. At the same time, the PLC controller controls the water temperature inside the water tank so that the water mist sprayed from multiple water mist nozzles is close to the temperature of the sub-wires and the busbar. This achieves the effect of cleaning the cable while it is twisting, while ensuring that the cleaning temperature is consistent with the temperature of the cable, preventing damage to the resistance value of the cable due to temperature difference.

[0027] 2. This invention moves the threaded post out of the threaded adjusting cap by rotating the threaded adjusting cap, thereby causing the lower cleaning sleeve and the upper cleaning sleeve to rotate and adjust their usage angle. At the same time, the first guide wheel can guide the sub-line during the laying process, thereby achieving the effect of adjusting the usage angle of the lower cleaning sleeve and the upper cleaning sleeve to adapt to sub-lines of different thicknesses and tensions.

[0028] 3. This invention extends the busbar from the inside of the hollow shaft and extends multiple sub-wires through the round holes on the side of the stranded wire holder. The sub-wires are then placed on the surfaces of multiple second guide wheels for guidance. The sub-wires are then passed through multiple limiting holes. At this point, the first drive motor can be started by the PLC controller, causing the drive shaft of the first drive motor to drive the gear to rotate. Under the meshing transmission of the gear and the gear plate, the hollow shaft will drive the guide plate and the limiting plate to rotate, thereby causing multiple sub-wires to rotate simultaneously. This achieves the effect of facilitating the rotation and twisting of multiple sub-wires, so that they are stranded on the outer wall of the busbar.

[0029] 4. This invention passes multiple strands of sub-wires and busbars through the interior of multiple threaded fastening sleeves, and then the adjustable cap can be rotated to make the threaded fastening sleeves made of spring steel retract inward, thereby limiting the sub-wires and busbars during the release of the wires. Then, the rebound force of multiple first springs causes multiple pressure rollers to squeeze the sub-wires and busbars, which can guide them and prevent them from becoming tangled as the sub-wires and busbars are continuously released.

[0030] 5. This invention passes the busbar through the interior of the parallel connector and the adjusting cover. The adjusting cover can then be rotated so that its inner wall is pressed against multiple adjusting rods. In turn, the multiple adjusting rods drive multiple pressure plates to converge into the interior of the parallel connector. Then, the twisting groove at the bottom of the pressure plate presses down on the sub-wire so that it adheres to the outside of the busbar. This fixes the position of the sub-wire and the busbar and prevents the sub-wire and the busbar from loosening due to internal stress after twisting.

[0031] 6. The present invention uses multiple feed rollers to place the sub-wires and main wires of the wire to be twisted, and then the fixed cap can be rotated to release the limit on the feed rollers and take them out from the top of the workbench. At the same time, the second drive motor drives the take-up roller to rotate and can wind up and place the twisted wire and cable. Attached Figure Description

[0049] 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 scope of protection of the present invention.

[0050] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8A stranding device for producing wires and cables includes: a workbench 1, a PLC controller 2 fixedly mounted on one side of the workbench 1, and a cleaning seat 4 fixedly mounted on the top surface of the workbench 1; a plurality of lower cleaning sleeves 13 are rotatably connected to the outer circular wall of the cleaning seat 4, and an upper cleaning sleeve 17 is rotatably connected to the top surface of the lower cleaning sleeves 13; a first semiconductor heating element 19 is fixedly mounted on one side of the upper cleaning sleeve 17 and one side of the lower cleaning sleeve 13; a water storage pipe 14 is fixedly mounted on one side of the cleaning seat 4, and a plurality of water mist nozzles 15 are fixedly sleeved on the inner circular wall of the water storage pipe 14, the water mist nozzles 15 corresponding to the positions of the lower cleaning sleeves 13; a first sliding sleeve 22 slides on one side of the inside of the cleaning seat 4, and a first temperature sensor is fixedly sleeved on the inner circular wall of the first sliding sleeve 22. 25. The first temperature sensor 25 is electrically connected to the water tank 3. An arc-shaped probe 26 is fixedly installed at one end of the probe rod of the first temperature sensor 25. A second sliding sleeve 27 is slidably connected to one side of the inner side of the cleaning seat 4. A limit plate 28 is fixedly installed on one side of the second sliding sleeve 27. Two threaded positioning blocks 23 are fixedly installed on one side of the cleaning seat 4. A first threaded rod 24 is rotatably connected to one side of both the first sliding sleeve 22 and the second sliding sleeve 27. The first threaded rod 24 is threadedly connected to the inner circular wall of the threaded positioning block 23. Two busbar cleaning covers 29 are provided on the inner circular wall of the cleaning seat 4. A second threaded rod 31 is fixedly installed on one side of the busbar cleaning cover 29. The second threaded rod 31 is threadedly connected to the cleaning seat 4. Two... A guide rod 32 is slidably connected to the cleaning seat 4. A second semiconductor heating element 30 is fixedly installed inside the busbar cleaning cover 29. Both the second semiconductor heating element 30 and the first semiconductor heating element 19 are electrically connected to the PLC controller 2. During the twisting process, the sub-wires of the wire and cable are passed between multiple lower cleaning sleeves 13 and upper cleaning sleeves 17, and then the lower cleaning sleeves 13 and upper cleaning sleeves 17 are connected and fixed with bolts. Then, the busbar of the wire and cable is passed between two busbar cleaning covers 29. Then, by rotating the two first threaded rods 24, the first sliding sleeve 22 and the second sliding sleeve 27 simultaneously approach the busbar of the wire and cable. At this time, the arc-shaped probe 26 at one end of the probe of the first temperature sensor 25 will be in contact with the surface of the busbar, and simultaneously limit the movement. Plate 28 provides auxiliary support to the other side of the busbar. Then, by rotating the two second threaded rods 31, the two busbar cleaning covers 29 are made to fit against the outer wall of the busbar. After the above steps are completed, the busbar and sub-wires can be twisted. The first temperature sensor 25 monitors the external temperature of the busbar in real time and feeds the data back to the PLC controller 2. The PLC controller 2 then controls the activation of the first semiconductor heating element 19 and the second semiconductor heating element 30. At this time, the first semiconductor heating element 19 and the second semiconductor heating element 30 will heat the lower cleaning sleeve 13, the upper cleaning sleeve 17, and the busbar cleaning cover 29 respectively, thus enabling the lower cleaning sleeve 13, the upper cleaning sleeve 17, and the busbar cleaning cover 29 to clean the busbar and sub-wires of the cable.To ensure the water temperature remains the same as that of the sub-line and busbar, the PLC controller 2 controls the water temperature inside the water tank 3 so that the water mist sprayed from the multiple water mist nozzles 15 is close to the temperature of the sub-line and busbar. This achieves the effect of cleaning the wires and cables during stranding while ensuring that the cleaning temperature is consistent with the temperature of the wires and cables, preventing damage to the resistance value of the wires and cables due to temperature difference. A mounting frame 8 is fixedly installed inside the workbench 1. Hot air boxes 33 are fixedly installed on the top and bottom surfaces of the mounting frame 8. A second hot air box 33 is fixedly installed on one side of the inside of the mounting frame 8. Temperature sensor 34, hot air box 33, and second temperature sensor 34 are all electrically connected to PLC controller 2. The two hot air boxes 33 and the second temperature sensor 34 allow the second temperature sensor 34 to detect the airflow temperature of the hot air box 33, and the PLC controller 2 controls the temperature of the hot air box 33. Thus, the hot air box 33 can dry the sub-wires and busbars of the wires and cables at the same temperature. A threaded post 18 is fixedly installed on the bottom surface of the lower cleaning sleeve 13, and a tensioning frame 20 is fixedly installed on one side of the lower cleaning sleeve 13. The tensioning frame 20 has an internal rotating connection... A first guide wheel 21 is connected to the outer circular wall of the cleaning seat 4, and several threaded adjusting caps 16 are rotatably connected to them. The inner circular wall of the threaded adjusting caps 16 is threadedly connected to the threaded post 18. By rotating the threaded adjusting caps 16, the threaded post 18 moves out of the threaded adjusting caps 16, thereby causing the lower cleaning sleeve 13 and the upper cleaning sleeve 17 to rotate, thus adjusting their operating angle. At the same time, the first guide wheel 21 can guide the sub-line during the unloading process, thereby adjusting the operating angle of the lower cleaning sleeve 13 and the upper cleaning sleeve 17 to adapt to sub-lines of different thicknesses and tensions. The system includes a water tank 3 fixedly installed inside the workbench 1. A submersible pump is fixedly installed on the bottom surface of the water tank 3, and a heating rod is fixedly installed on one side of the water tank 3. Both the submersible pump and the heating rod are electrically connected to a PLC controller 2. The inner circular wall of the submersible pump outlet is fixedly fitted to a water storage pipe 14. The PLC controller 2 controls the heating rod to heat the water inside the water tank 3 to a temperature suitable for the sub-line and busbar. The hot water is then output to the inside of the water storage pipe 14 via the submersible pump and sprayed onto the outside of the sub-line and busbar through water mist nozzles 15 for humidification and cleaning.

[0051] Based on the above embodiments, refer to Figure 2 , Figure 9 , Figure 10 , Figure 11 and Figure 12A stranded wire holder 5 is fixedly installed on the top surface of the workbench 1. A protective cover 40 is fixedly installed on one side of the stranded wire holder 5. A first drive motor 41 is fixedly installed on the outer circular wall of the protective cover 40. The first drive motor 41 is electrically connected to the PLC controller 2. A gear 42 is fixedly installed on the bottom surface of the drive shaft of the first drive motor 41. A hollow rotating shaft 35 is rotatably connected to one side of the stranded wire holder 5. A gear plate 39 is fixedly sleeved on the outer circular wall of the hollow rotating shaft 35. The gear plate 39 and the gear 42 are meshed. A guide plate 11 is fixedly sleeved on the outer circular wall of the hollow rotating shaft 35. Several second guide wheels 36 are rotatably connected inside the guide plate 11. A limit plate 37 is fixedly sleeved on the outer circular wall of the hollow rotating shaft 35. Several limiting holes 38 are provided on one side. By extending the main wire from the inside of the hollow rotating shaft 35 and passing through the round holes on the side of the stranded wire seat 5, multiple sub-wires are extended and placed on the surface of multiple second guide wheels 36 for guidance. Then, the sub-wires are passed through the multiple limiting holes 38. At this time, the first drive motor 41 can be started by the PLC controller 2, so that the drive shaft of the first drive motor 41 drives the gear 42 to rotate. Under the meshing transmission of the gear 42 and the gear plate 39, the hollow rotating shaft 35 will drive the guide plate 11 and the limiting plate 37 to rotate, thereby causing multiple sub-wires to rotate and twist simultaneously. The guide seat 7 is fixedly installed on the top surface of the workbench 1. Several threaded fastening sleeves 45 are fixedly installed on one side of the guide seat 7. One end of the threaded fastening sleeve 45 is tapered. The outer circular wall of the threaded fastening sleeve 45 is threaded. An adjusting cap 46 is threaded to the outer circular wall of the threaded fastening sleeve 45. The inner wall of the adjusting cap 46 is tapered. Several rotating disks 47 are rotatably connected to the other side of the guide seat 7. The rotating disks 47 correspond to the positions of the threaded fastening sleeves 45. Two limiting seats 48 are fixedly installed on one side of the rotating disks 47. The two limiting seats 48 are spaced apart. The mounting shell 49 is slidably connected inside the limiting seat 48. Two rotatably connected inside the mounting shell 49 are rotatably connected. The pressure roller 50 and the inner circular wall of the limiting seat 48 are fixedly sleeved with a first mounting cylinder 54. The first mounting cylinder 54 is movably sleeved with a first spring 52. The first mounting cylinder 54 is slidably connected with a first connecting post 53. The bottom surface of the first connecting post 53 is fixedly installed with the mounting shell 49. By passing multiple sub-wires and busbars through the interior of multiple threaded fastening sleeves 45, the adjusting cap 46 can be rotated to make the threaded fastening sleeves 45 made of spring steel retract inward, thereby limiting the sub-wires and busbars when they are released. Then, the rebound force of multiple first springs 52 causes multiple pressure rollers 50 to squeeze the sub-wires and busbars, which can guide them and prevent them from becoming tangled when the sub-wires and busbars are continuously released.

[0052] Based on the above embodiments, refer to Figure 2 , Figure 13 , Figure 14 , Figure 15 and Figure 16 A parallel connector 9 is fixedly installed on the top surface of the workbench 1. Several pressure plates 56 are arranged inside the parallel connector 9. An adjusting rod 58 is fixedly installed at one end of each pressure plate 56. A twisting groove, which is arc-shaped, is opened on the bottom surface of the pressure plate 56. An adjusting cover 55 is threadedly connected to one side of the parallel connector 9. One side of the adjusting cover 55 is inclined. Several second mounting cylinders 57 are fixedly installed on the inner circular wall of the parallel connector 9. Every two second mounting cylinders 57 and one pressure plate 56 form a group. The second mounting cylinders 57... An internal sliding connection is provided with a second connecting post 59. A second spring 60 is movably sleeved on the outer circular wall of the second connecting post 59. The bottom surface of the second connecting post 59 is fixedly installed with the pressure plate 56. By passing the busbar through the interior of the parallel connector 9 and the adjusting cover 55, the adjusting cover 55 can be rotated to cause its inner wall to press against multiple adjusting rods 58. In turn, the multiple adjusting rods 58 drive multiple pressure plates 56 to retract into the interior of the parallel connector 9. Then, the twisting groove at the bottom of the pressure plate 56 presses down on the sub-wire to make it fit against the busbar. The external of the wire allows for the fixing of the positions of the sub-wires and the main wires, preventing them from loosening due to internal stress after twisting. Several positioning sleeves 43 are fixedly installed on the top surface of the workbench 1. The inner circular wall of the positioning sleeve 43 is threaded, and the outer circular wall of the positioning sleeve 43 is rotatably connected to the wire feeding wheel 6. The internal thread of the positioning sleeve 43 is connected to the fixing cap 44. The top surface of the workbench 1 is fixedly installed with a mounting frame 10. The internal rotatably connected to the mounting frame 10 is the take-up wheel 12. A second drive motor 51 is fixedly installed on one side of the mounting frame 10. The second drive motor 51 is electrically connected to the PLC controller 2. One end of the drive shaft of the second drive motor 51 is fixedly installed to the take-up wheel 12. The sub-wires and main wires to be twisted can be placed through the multiple wire feeding wheels 6. Then, the fixing cap 44 can be rotated to release the restriction on the wire feeding wheel 6 and remove it from the top of the workbench 1. At the same time, the second drive motor 51 drives the take-up wheel 12 to rotate, which can be used to wind up and place the twisted wires and cables.

[0053] Working principle: Please refer to Figures 1-16As shown, during the twisting process, the sub-wires of the wire and cable are passed between multiple lower cleaning sleeves 13 and upper cleaning sleeves 17, and then the lower cleaning sleeves 13 and upper cleaning sleeves 17 are connected and fixed with bolts. The busbar of the wire and cable is then passed between two busbar cleaning covers 29. Next, by rotating the two first threaded rods 24, the first sliding sleeve 22 and the second sliding sleeve 27 simultaneously approach the busbar of the wire and cable. At this time, the arc-shaped probe 26 at one end of the probe of the first temperature sensor 25 will be in contact with the surface of the busbar. Simultaneously, the limiting plate 28 will provide auxiliary support on the other side of the busbar. Then, by rotating the two second threaded rods 31, the two busbar cleaning covers 29 will be in contact with the outer wall of the busbar. After the above steps are completed, the busbar and sub-wires can be twisted. The first temperature sensor 25 will then monitor the temperature outside the busbar in real time and feed the data back. The PLC controller 2 is then activated, controlling the first semiconductor heating element 19 and the second semiconductor heating element 30. At this time, the first semiconductor heating element 19 and the second semiconductor heating element 30 heat the lower cleaning sleeve 13, the upper cleaning sleeve 17, and the busbar cleaning cover 29 respectively. This ensures that when the lower cleaning sleeve 13, the upper cleaning sleeve 17, and the busbar cleaning cover 29 clean the busbars and sub-wires of the cable, they maintain the same temperature as the sub-wires and busbars. Simultaneously, the PLC controller 2 controls the water temperature inside the water tank 3 so that the water mist sprayed from the multiple water mist nozzles 15 is close to the temperature of the sub-wires and busbars. This achieves the effect of cleaning the cables during twisting while ensuring that the cleaning temperature is consistent with the cable temperature, preventing damage to the cable's resistance due to temperature differences.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Through the two hot air boxes and the second temperature sensor, the second temperature sensor can detect the airflow temperature of the hot air boxes, and the PLC controller can control the temperature of the hot air boxes. Thus, the hot air boxes can dry the sub-wires and busbars of the wires and cables at the same temperature.

3. A stranding device for producing wires and cables according to claim 1, characterized in that: A threaded post is fixedly installed on the bottom surface of the lower cleaning sleeve, and a tensioning frame is fixedly installed on one side of the lower cleaning sleeve. The tensioning frame is rotatably connected to a first guide wheel. Several threaded adjusting caps are rotatably connected to the outer circular wall of the cleaning seat. The inner circular wall of the threaded adjusting cap is threadedly connected to the threaded post. By rotating the threaded adjusting cap, the threaded post moves out of the threaded adjusting cap, thereby causing the lower and upper cleaning sleeves to rotate and their operating angles to be adjusted. At the same time, the first guide wheel can guide the sub-line during the laying process, thereby adjusting the operating angles of the lower and upper cleaning sleeves to adapt to sub-lines of different thicknesses and tensions.

The inner circular wall of the submersible pump outlet is fixedly sleeved with the water storage pipe. The PLC controller can control the heating rod to heat the water inside the water tank to a temperature suitable for the sub-line and busbar. The hot water is then output to the inside of the water storage pipe through the submersible pump, and then sprayed onto the outside of the sub-line and busbar through water mist nozzles to humidify and clean them.

5. A stranding device for producing wires and cables according to claim 1, characterized in that: A stranded wire holder is fixedly installed on the top surface of the workbench. A protective cover is fixedly installed on one side of the stranded wire holder. A first drive motor is fixedly installed on the outer circular wall of the protective cover. The first drive motor is electrically connected to the PLC controller. A gear is fixedly installed on the bottom surface of the drive shaft of the first drive motor. A hollow shaft is rotatably connected to one side of the stranded wire holder. A gear plate is fixedly sleeved on the outer circular wall of the hollow shaft. The gear plate and the gear are meshed. A guide plate is fixedly sleeved on the outer circular wall of the hollow shaft. Several second guide wheels are rotatably connected inside the guide plate. A limit plate is fixedly sleeved on the outer circular wall of the hollow shaft. Several limit holes are opened on one side of the limit plate. By extending the busbar from the inside of the hollow shaft and passing multiple sub-wires through the round holes on the side of the stranded wire holder, the sub-wires are placed on the surfaces of multiple second guide wheels for guidance. Then, the sub-wires are passed through multiple limit holes. At this point, the first drive motor can be started by the PLC controller, causing the drive shaft of the first drive motor to drive the gear to rotate. Under the meshing transmission of the gear and the gear plate, the hollow shaft will drive the guide plate and the limit plate to rotate, which will cause multiple sub-wires to rotate simultaneously, thus facilitating the rotation and twisting of the multiple sub-wires and making them stranded on the outer wall of the busbar.

6. A stranding device for producing wires and cables according to claim 1, characterized in that: A guide seat is fixedly installed on the top surface of the workbench. Several threaded fastening sleeves are fixedly installed on one side of the guide seat. One end of each threaded fastening sleeve is tapered, and the outer circular wall of the sleeve is threaded. An adjusting cap is threaded onto the outer circular wall of the sleeve, and the inner wall of the adjusting cap is tapered. Several rotating discs are rotatably connected to the other side of the guide seat. The rotating discs correspond to the positions of the threaded fastening sleeves. Two limit seats are fixedly installed on one side of each rotating disc, spaced apart. A mounting shell is slidably connected inside each limit seat, and two pressure rollers are rotatably connected inside the mounting shell. The inner circular wall of the limit seat... A first mounting cylinder is fixedly sleeved on the surface. A first spring is movably sleeved inside the first mounting cylinder. A first connecting column is slidably connected inside the first mounting cylinder. The bottom surface of the first connecting column is fixedly installed with the mounting shell. By passing multiple strands of sub-wires and busbars through the interior of multiple threaded fastening sleeves, the adjustable cap can be rotated to cause the threaded fastening sleeves made of spring steel to retract inward, thereby limiting the sub-wires and busbars during the release of the wires. Then, the rebound force of multiple first springs causes multiple pressure rollers to squeeze the sub-wires and busbars, which can guide them during the continuous release of the sub-wires and busbars and prevent them from becoming tangled.

7. A stranding device for producing wires and cables according to claim 1, characterized in that: A parallel connector is fixedly installed on the top surface of the workbench. The parallel connector contains several pressure plates, one end of which is fixedly fitted with an adjusting rod. The bottom surface of the pressure plate has a twisting groove, which is arc-shaped. An adjusting cover is threaded onto one side of the parallel connector. One side of the adjusting cover is inclined. Several second mounting cylinders are fixedly installed on the inner circular wall of the parallel connector. Each group consists of two second mounting cylinders and one pressure plate. A second connecting column is slidably connected inside the second mounting cylinder. A second spring is movably sleeved on the outer circular wall of the second connecting column. The bottom surface of the second connecting column is fixedly installed with the pressure plate. By passing the busbar through the parallel connector and the adjusting cover, the adjusting cover can be rotated to press its inner wall against multiple adjusting rods. These adjusting rods then drive multiple pressure plates to converge towards the interior of the parallel connector. The twisting groove at the bottom of the pressure plate then presses down on the sub-wire, causing it to adhere to the outside of the busbar. This fixes the position of the sub-wire and busbar, preventing loosening due to internal stress after twisting.

A wire take-up wheel is rotatably connected inside the mounting frame. A second drive motor is fixedly installed on one side of the mounting frame. The second drive motor is electrically connected to the PLC controller. One end of the drive shaft of the second drive motor is fixedly installed to the wire take-up wheel. The multiple wire feeding wheels can be used to place the sub-wires and main wires of the wire to be twisted. Then, the fixing cap can be rotated to release the restriction on the wire feeding wheel and remove it from the top of the workbench. At the same time, the second drive motor drives the wire take-up wheel to rotate and place the twisted wire and cable.
