Description

Technical Field

[0001] This invention belongs to the field of cable processing technology, specifically a multi-core cable processing and stranding equipment. Background Technology

[0002] Cables, as the core carriers of power transmission and signal transmission, are often designed with multi-core structures and are widely used in power engineering, communication networks, and industrial manufacturing. Because single metal wires have poor flexibility and are easily broken, they cannot directly adapt to complex laying environments. Therefore, a stranding process must be used to intertwine multiple single wires according to specific rules. The stranding process is a crucial step in wire and cable manufacturing. Its core principle is to physically bind multiple conductors together tightly to improve the conductor's conductivity, enhance mechanical strength, and improve fatigue resistance. The implementation steps of this process typically include core preparation and cleaning, equipment selection and process parameter setting, real-time control and adjustment of the stranding process, and post-stranding visual inspection and performance testing.

[0003] However, in existing multi-core cable manufacturing stranding equipment, if the tensioning system is poorly designed or the guiding mechanism lacks precision, the cable cores are prone to tilting or uneven stress during sliding. This easily leads to problems such as uneven stranding and core eccentricity. Uneven stranding disrupts the roundness of the cable core, causing eccentricity in subsequent insulation extrusion stages, resulting in uneven insulation layer thickness and weak points, increasing the risk of breakdown. It also affects the overall mechanical properties and structural stability of the cable, making it more susceptible to damage during laying and use. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a multi-core cable processing and stranding device, which solves the problem that tilting or uneven force may occur during the core sliding process, leading to core eccentricity and uneven stranding, ultimately resulting in uneven insulation layer thickness and weak points, affecting the cable's mechanical properties and structural stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-core cable processing and stranding device, comprising a workbench and a set of wire cores, wherein a bearing mechanism is provided on the workbench, and a set of buffer mechanisms and tensioning mechanisms are circumferentially and equidistantly arranged on the bearing mechanism, and a stranding mechanism is provided at the end of the bearing mechanism; The tensioning mechanism includes a sleeve fixed to the outer periphery of the bearing mechanism and a bearing plate hinged to the outer periphery of the bearing mechanism, wherein the bearing plate is designed to be inclined. A metal rod is axially slidably engaged inside the sleeve, and a limit cage is slidably engaged at the bottom of the metal rod. A pressure sensor is provided in the middle of the limit cage, and the limit cage is connected to the inside of the sleeve by a tension spring. The top of the metal rod slides and is hinged to the bottom of the support plate; Each of the aforementioned wire cores passes through a buffer mechanism and a support plate and is finally connected to a stranding mechanism; The wire core is released through the unwinding mechanism, and the twisted wire core is connected to the winding mechanism.

[0006] Preferably, the bearing plate includes an upper template and a lower template. The upper template is connected to the lower template by a set of bolts. After the upper template and the lower template are combined into a whole, their contact parts are provided with slots for penetrating the wire core. The metal rod is hinged and slidably engaged with the bottom of the upper template.

[0007] Preferably, the two ends of the upper template are designed to be bent downwards, and the two ends of the lower template are designed to be bent upwards, with the bent portions of both the upper and lower templates being rounded.

[0008] Preferably, under normal operating conditions, the core wire presses the bearing plate downwards and folds it over. The bearing plate presses the limiting cage downwards through the metal rod. The limiting cage stretches the tension spring a certain distance, and the pressure sensor does not bear pressure.

[0009] Preferably, when the length of any of the wire cores released by the wire release mechanism increases, the pressure on the support plate from the wire core decreases, the tension spring pulls the limiting cage upward, and the pressure sensor presses the bottom of the metal rod and sends an alarm to the computer. The limiting cage pushes the support plate upward through the metal rod to support the wire core and compensate for the excess length of the wire core released.

[0010] Preferably, when the wire feeding mechanism jams, causing the length of any of the wire cores to be released to shorten, the pressure on the support plate increases due to the wire core. The support plate folds downward and pushes the metal rod to retract into the sleeve. At the same time, the metal rod pushes the limiting cage down and presses the pressure sensor, which then sends an alarm to the computer.

[0011] Preferably, the bearing mechanism includes a bearing shaft fixedly mounted on the worktable, the sleeve fixedly mounted on the bearing shaft, and the upper template hinged to the bearing shaft; A constraint is provided at each end of the bearing shaft; Each of the aforementioned restrainers includes a limiting cylinder fixed to the end of the bearing shaft. A set of limiting grooves and positioning grooves are respectively provided circumferentially on the outer periphery and the end of the limiting cylinder, and the wire core can pass through the positioning grooves and the limiting grooves.

[0012] Preferably, any of the buffer mechanisms includes two rollers fixed on a bearing shaft, and rollers are slidably engaged on the bearing shaft. The core wires are S-shaped and wound around two rollers, roller one and roller two, respectively. A damper is fixedly mounted on the bearing shaft, and the end of the damper is fixedly connected to the second roller.

[0013] Preferably, the twisting mechanism includes a motor fixed on the workbench and two support plates. Each support plate has a sponge block inside. A twisting ring is rotatably engaged on the inner side of each of the two support plates. The tops of the two support plates are connected to an oil can filled with lubricating oil. A set of oil grooves communicating with the support plates are arranged circumferentially on the twisting ring. It also includes two meshing gears, one of which is connected to the motor drive, and the other gear is fixedly mounted on two hinge rings.

[0014] Preferably, the limiting cylinder is fixed to one of the support plates by a protective cylinder, the top of the oil can is provided with an opening and is closed by a knob cover, and the inner wall of the twisted ring is wavy and adapted to the wire core.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordination of structures such as a tensioning mechanism, triggers an alarm when multiple cores are released, reducing the pressure on the support plate and causing a significant change in the pressure sensor reading. This alerts workers to troubleshoot the problem. A tension spring, via a limiting cage and a metal rod, pulls the support plate upwards, supporting the cores and restoring them to the same tension as the other cores. If the release distance of a particular core is shortened, the pressure on the support plate increases, causing excessive changes in the pressure sensor reading, triggering an alarm. This allows production line personnel to react quickly to the fault. Simultaneously, the metal rod descends to compensate for the missing core, effectively preventing uneven stranding and other problems, providing reaction time for maintenance, avoiding downtime due to minor issues, and increasing the device's fault tolerance.

[0016] This invention, through the cooperation of a buffer mechanism and other structures, allows the wire core to pass through the upper layer of one of the rollers, preventing it from sliding directly to the edge of the limiting groove and getting scratched. It then sequentially connects to another roller and roller two in an S-shape. When the wire core shakes, the positioning and limiting grooves filter out a portion of it. The shaking inevitably causes a change in the length of the wire core connected to the stranding mechanism. If the shaking continues, the change is transmitted to the damper by roller two, thus buffering the movement and further ensuring that the shaking and swaying of the wire core do not interfere with the stranding quality.

[0017] This invention, through the coordinated arrangement of structures such as a twisting mechanism, allows the motor to drive two gears to rotate, which in turn drives two twisting rings to rotate synchronously. The constraint device is a fixed design, thus enabling the individual wire cores to be twisted into a whole. The lubricating oil in the oil reservoir flows to the sponge block and then penetrates downwards into the oil groove and onto the wire cores. This prevents damage to the outer layer caused by cable friction during the winding process and also prevents scratches from occurring when the wire cores slide against the inner wall of the twisting rings.

[0020] 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.

[0021] like Figures 1 to 11 As shown, the present invention provides a multi-core cable processing and stranding device, including a workbench 1 and a set of wire cores 6. A bearing mechanism 2 is provided on the workbench 1. A set of buffer mechanisms 3 and tensioning mechanisms 4 are arranged circumferentially and at equal intervals on the bearing mechanism 2. A stranding mechanism 5 is provided at the end of the bearing mechanism 2. The tensioning mechanism 4 includes a sleeve 41 fixed to the outer periphery of the bearing mechanism 2 and a bearing plate 46 hinged to the outer periphery of the bearing mechanism 2. The bearing plate 46 is designed to be inclined. A metal rod 42 is axially slidably engaged inside the sleeve 41. A limit cage 44 is slidably engaged at the bottom of the metal rod 42. A pressure sensor 45 is provided in the middle of the limit cage 44. The limit cage 44 is connected to the inside of the sleeve 41 by a tension spring 43. The top of the metal rod 42 slides and is hinged to the bottom of the support plate 46; Each wire core 6 passes through each buffer mechanism 3 and the carrier plate 46 and is finally connected to the stranding mechanism 5; The wire core 6 is released through the unwinding mechanism, and the twisted wire core 6 is then connected to the winding mechanism.

[0022] When the wire feeding mechanism causes an increase in the length of any of the wire cores 6 released, the pressure on the support plate 46 from the wire core 6 decreases. The tension spring 43 pulls the limit cage 44 upward, and the pressure sensor 45 presses the bottom of the metal rod 42 and sends an alarm to the computer. The limit cage 44 pushes the support plate 46 upward through the metal rod 42 to support the wire core 6 and compensate for the excess length of the wire core 6 released.

[0023] Under normal operating conditions, the core 6 presses the bearing plate 46 downward and folds it over. The bearing plate 46 presses the limiting cage 44 down through the metal rod 42. The limiting cage 44 pulls the tension spring 43 to extend a certain distance, and the pressure sensor 45 does not bear pressure.

[0024] When the wire feeding mechanism jams, causing the length of any wire core 6 to be released to shorten, the pressure on the support plate 46 increases due to the wire core 6. The support plate 46 folds downward and pushes the metal rod 42 to retract into the sleeve 41. At the same time, the metal rod 42 pushes the limit cage 44 down and presses the pressure sensor 45. The pressure sensor 45 sends an alarm to the computer.

[0025] Using the above scheme: each wire core 6 is first released from the unwinding mechanism, and then passes through the buffer mechanism 3, the bearing plate 46 and the twisting mechanism 5 in sequence, and finally connected to the winding mechanism; In actual operation, the speed at which the wire core 6 is released by the wire release mechanism is always less than the speed at which the wire winding mechanism winds the cable. This ensures that the wire core 6 remains taut, thereby preventing the wire core 6 from bending and causing eccentricity or uneven twisting. When the twisting operation begins, the core 6 is tightened, and the resulting pressure will force the bearing plate 46 to fold downwards. During this process, the metal rod 42 is forced to descend. The metal rod 42 is stretched by the tension spring 43 through the limiting cage 44. However, because the elasticity of the tension spring 43 is always present, the metal rod 42 will not completely retract into the sleeve 41 during the operation, so that the metal rod 42 still has room for vertical movement. As mentioned in the above scheme, if the wire feeding mechanism malfunctions or if the wire core 6 is bent when it is initially wound up in the wire feeding mechanism, the wire core 6 at that point will be released by the other wire cores 6, which is the initial cause of uneven twisting and cable eccentricity. It is important to note that because the wire core 6 is released a certain distance, the pressure on the corresponding bearing plate 46 will be less than that on other bearing plates 46, and the wire core 6 will be loose on the bearing plate 46 at that point. However, the corresponding tension spring 43 will immediately pull the metal rod 42 upward through the limiting cage 44. The metal rod 42 pulls the bearing plate 46 upward, thereby supporting the wire core 6 to return to the same taut state as the other wire cores 6. At this time, the pressure exerted on each bearing plate 46 by each wire core 6 is the same, and the excess released wire core 6 is replaced by the folding and supporting of the bearing plate 46. This can effectively prevent the excess wire core 6 from causing various problems such as uneven twisting, eccentricity, and cable bending in the future. During this period, if the pressure borne by the support plate 46 is reduced, the pressure applied by the support plate 46 and the metal rod 42 to the pressure sensor 45 will immediately change significantly. When the change in value exceeds the process setting value, the pressure sensor 45 will immediately send an alarm to the computer to remind the staff to carry out fault repair, which further ensures production quality and production line safety. Assuming the wire feeding mechanism malfunctions and jams, causing a shortened release distance for a certain wire core 6, the pressure exerted on the support plate 46 by that wire core 6 immediately increases. This will push the metal rod 42 to press against the pressure sensor 45, causing the value monitored by the pressure sensor 45 to exceed the process setting value, triggering an alarm. This allows production line personnel to react quickly to the fault. As described in the above workflow, the metal rod 42 has a margin for vertical movement during operation, so the release distance of the wire core 6 is relatively small. When the pressure on the support plate 46 increases, the metal rod 42 descends, thus compensating for the missing wire core 6. This effectively provides workers with reaction time for maintenance, while avoiding downtime for maintenance due to minor issues, greatly improving the fault tolerance of the device.

[0026] like Figures 1-7 As shown, the bearing plate 46 includes an upper template 461 and a lower template 462. The upper template 461 is connected to the lower template 462 by a set of bolts. After the upper template 461 and the lower template 462 are combined into a whole, their contact parts are provided with slots for penetrating the wire core 6. The metal rod 42 is hinged and slidably engaged at the bottom of the upper template 461.

[0027] The above solution is adopted: In the actual maintenance process, if the wire core 6 is stuck between the upper template 461 and the lower template 462, the upper template 461 and the lower template 462 can be separated by removing the bolts on the lower template 462, and the slots on both can be cleaned. This ensures the reliability of the device and the convenience of maintenance. Furthermore, both the upper template 461 and the lower template 462 are provided with semi-circular grooves of the same size. After the two are fastened with bolts, they are combined into a whole circular groove. Therefore, there is no problem of the wire core 6 getting stuck in either the upper template 461 or the lower template 462 groove, which improves the convenience of device maintenance and avoids the outer layer damage to the wire core 6.

[0028] like Figures 1-7 As shown, the two ends of the upper template 461 are curved downwards, and the two ends of the lower template 462 are curved upwards. The curved parts of both the upper template 461 and the lower template 462 are rounded.

[0029] The above solution is adopted: During the stranding process, the bearing plate 46 is folded up and down. When the bearing plate 46 is folded up, the wire core 6 contacts the bent part of the upper template 461. When the bearing plate 46 is folded down, the wire core 6 contacts the bent part of the lower template 462. This can protect the wire core 6 from being scratched by the edge of the bearing plate 46, further ensuring the quality of the finished cable and preventing rework in the future.

[0030] like Figures 1-10As shown, the bearing mechanism 2 includes a bearing shaft 21 fixedly mounted on the workbench 1, a sleeve 41 fixedly mounted on the bearing shaft 21, and an upper template 461 hinged to the bearing shaft 21. A constraint 22 is provided at each end of the bearing shaft 21; Each constraint device 22 includes a limiting cylinder 221 fixed to the end of the bearing shaft 21. A set of limiting grooves 222 and positioning grooves 223 are respectively arranged circumferentially on the outer periphery and the end of the limiting cylinder 221. The wire core 6 can pass through the positioning groove 223 and the limiting groove 222.

[0031] Using the above scheme: the wire core 6 first passes through the positioning groove 223 and the limiting groove 222 in one of the constraint devices 22, and then sequentially connects to the buffer mechanism 3 and the tensioning mechanism 4. Then it passes through the positioning groove 223 and the limiting groove 222 in the other constraint device 22 and connects to the twisting mechanism 5. This can limit the position of the wire core 6 and prevent it from shaking and deviating due to excessive gap distance.

[0032] like Figures 1-5 As shown, any buffer mechanism 3 includes two rollers 31 fixed on the bearing shaft 21, and roller 32 slidably engaged on the bearing shaft 21. The wire core 6 is wound in an S-shape around two rollers 31 and 32 respectively; A damper 33 is fixedly mounted on the bearing shaft 21, and the end of the damper 33 is fixedly connected to the roller 32.

[0033] The above solution is adopted: such as Figure 5 The wire core 6 shown in the figure passes through the upper layer of one of the rollers 31 first. This can prevent the wire core 6 from sliding directly to the edge of the limiting groove 222 during the process of passing through the limiting groove 222, thus avoiding scratches. It then connects to the lower layer of another roller 31 and wraps around to the lower layer of roller 32, and finally connects to the support plate 46 from the upper layer of roller 32; When the core 6 shakes due to external reasons, the positioning groove 223 and the limiting groove 222 filter out a portion of it. The shaking will inevitably cause the length of the core 6 connected to the stranding mechanism 5 to change. If the shaking continues, it will be transmitted to the damper 33 by the roller 2 32 to buffer it, further ensuring that the shaking and swaying of the core 6 and other unexpected situations will not interfere with the quality of stranding.

[0034] like Figures 1-11As shown, the twisting mechanism 5 includes a motor 51 fixed on the workbench 1 and two support plates 52. Each support plate 52 has a sponge block 521 inside. The inner side of each support plate 52 is rotatably engaged with a twisting ring 56. The top of the two support plates 52 is connected to an oil can 53. The oil can 53 is filled with lubricating oil. The twisting ring 56 has a set of oil grooves 561 circumferentially arranged on it, which are connected to the support plates 52. It also includes two meshing gears 511, one of which is connected to the motor 51 for transmission, and the other gear 511 is fixedly mounted on two hinge rings 56.

[0035] The limiting cylinder 221 is fixed to one of the support plates 52 by the protective cylinder 55. The top of the oil can 53 is provided with an opening and is closed by the knob cover 54. The inner wall of the twisting ring 56 is wavy and is adapted to the wire core 6.

[0036] Using the above scheme: after the wire core 6 passes through the positioning groove 223, it passes through the stranding ring 56 in a circular arrangement, and each wire core 6 is stuck in the wave groove on the inner wall of the stranding ring 56, and finally connected to the winding equipment. After the preparation is completed, the motor 51 drives the two gears 511 to rotate, and the gears 511 drive the two twisted rings 56 to rotate synchronously. The constraint device 22 is a fixed design, so it can twist the individual wire cores 6 into a whole. During this process, the lubricating oil in the oil can 53 flows to the sponge block 521 and penetrates downwards to the oil groove 561 and the wire core 6. This prevents damage to the outer layer caused by cable friction during the winding process, and also prevents scratches from occurring when the wire core 6 slides on the inner wall of the stranding ring 56.

[0037] Working principle and usage process of this invention: The wire core 6 passes through the buffer mechanism 3, the bearing plate 46 and the twisting mechanism 5, and is finally connected to the winding mechanism. When the stranding mechanism 5 starts stranding and the winding mechanism starts winding the core 6, the pressure generated by the tension of the core 6 forces the bearing plate 46 to fold downwards, and at the same time forces the metal rod 42 to descend. The metal rod 42 is stretched by the tension spring 43 through the limiting cage 44, but the metal rod 42 will not retract completely and can still move up and down. Suppose that a portion of the wire core 6 at a certain point is released from the other wire cores 6, the pressure on the corresponding bearing plate 46 is less than that on the other bearing plates 46. The corresponding tension spring 43 immediately pulls the metal rod 42 upward through the limiting cage 44. The metal rod 42 pulls the bearing plate 46 to fold upward, thereby supporting the wire core 6 to return to the same taut state as the other wire cores 6. The portion of the excess released wire core 6 is replaced by the folding support of the bearing plate 46. During the aforementioned period, the pressure borne by the bearing plate 46 is reduced, and the pressure of the wire core 6, after passing through the bearing plate 46 and the metal rod 42, causes a significant change in the value displayed on the pressure sensor 45, and an alarm is immediately triggered to alert the staff. Assuming that the release distance of a certain core 6 is shortened, the pressure exerted by the core 6 on the bearing plate 46 immediately increases. The value monitored by the pressure sensor 45 exceeds the process setting value, and an alarm is triggered. The metal rod 42 descends to compensate for the missing core 6.
