Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically to a cable forming machine. Background Technology

[0002] Cable forming machines are the main equipment used in wire and cable factories to produce power cables, plastic-insulated cables, and rubber-sheathed cables. These machines are specifically designed for manufacturing four-core and five-core plastic-insulated and cross-linked cables with a cross-sectional area of ​​25-240 mm², including armored versions. They are redesigned based on advanced domestic and international cable forming equipment and adapted to the specific conditions of my country's wire and cable production. The machine's structure consists of a transmission device, winch, double-row wire mold base, wrapping head, steel strip head, meter counter, traction device, take-up and unwinding frame, and electrical control system.

[0003] Chinese Patent CN119132746B discloses a cable forming machine. The cable forming machine includes a conductor placement frame, on which a conductor mounting roller is rotatably mounted. One end of the conductor placement frame is rotatably connected to a conductor tube. A first gear, a protective wire placement disc, a guide disc, and a stranding disc are sequentially fixed and mounted on the conductor tube. A die head is placed in front of the conductor tube. The first gear meshes with a second gear, and the end of the second gear is rotatably connected to the conductor placement frame. By driving the guide disc to rotate, the conductor wheels in the six sets of mounting slots on the guide disc can sequentially contact the lubricating oil in the oil tank. The lubricated conductor wheels apply lubricating oil to the protective wire, thereby achieving lubrication of the protective wire.

[0004] The structural design of the above-mentioned related technologies is as follows: Although the cable can be lubricated during the cable stranding process, the tension between the conductors is different before the cable is stranded, resulting in some conductors being too tight and some conductors still being loose, which affects the quality of the stranded cable. When stranding to the end of the conductor, the conductor is separated from the stranding reel, making it difficult to control the tension of the conductor. Therefore, it is necessary to use other machinery for stranding or to cut off the end of the conductor, resulting in material waste.

[0005] Therefore, a cable forming machine was proposed to solve the problems mentioned above. Summary of the Invention

[0006] This invention provides a cable forming machine, which aims to solve the problem of difficulty in controlling the tension of conductors before and after stranding in related technologies.

[0007] The cable forming machine of the present invention includes a base frame, a stranding mechanism on the base frame, an installation mechanism slidably connected to the stranding mechanism, and a plurality of tensioning mechanisms for tensioning conductors on the installation mechanism. The tensioning mechanism includes a rotating component disposed in the installation mechanism, a pressure component that is elastically slidably disposed inside the lower part of the rotating component, and a clamping component that is elastically slidably disposed inside the upper part of the rotating component, with the pressure component and the clamping component connected. The rotating assembly includes a mounting base mounted on the mounting mechanism, a mounting bracket rotatably connected to the mounting base, and a rotating rod rotatably connected inside the mounting bracket, with the clamping assembly located above the rotating rod; The wire clamping assembly includes a movable plate that is flexibly slidably connected in the mounting frame, a wire guide groove opened at the end of the movable plate, a wire clamping wheel that is rotatably connected in the wire guide groove, and slide rods installed on both sides of the movable plate. The movable plate is inclined in the mounting frame, and the slide rods are connected to the clamping assembly to drive the clamping assembly to clamp the wire.

[0008] Before stranding the wires, pull the end of the wire from the stranding mechanism, then let the wire enter the wire passage groove of the movable plate and contact the pressure wheel. At this time, pull the mounting bracket upward to lift the clamping assembly, causing the clamping assembly to move upward. After the clamping assembly moves upward, pass the wire between the rotating rod and the clamping assembly, and finally connect the wire to the stranding device. After the wire is connected to the stranding device, push the mounting mechanism to move. The mounting mechanism drives the movable plate to move through the mounting bracket. During the movement of the movable plate, the pressure wheel moves along the inclined direction of the wire, and at the same time, the movable plate gradually moves upward along the inclined direction of the wire, thereby clamping the wire so that the beginning of the wire is tensioned before stranding. When the end of the wire is disengaged from the stranding mechanism, the movable plate returns to its original position and drives the clamping assembly to contact the rotating rod through the slide rod, thereby clamping the wire so that the end of the wire is tensioned and prevents the end of the wire from losing tension and becoming loose.

[0009] Preferably, the mounting mechanism includes a mounting plate slidably connected to the hinge mechanism and a receiving groove formed on the mounting plate. The mounting plate has a cavity inside, the mounting seat is mounted on the inner bottom wall of the receiving groove, and a notch is formed on one side of the bottom of the receiving groove.

[0010] Preferably, the pressure wire assembly further includes a slider 1 installed on the bottom of both sides of the movable plate and a connecting shaft installed on the slider 1. The bottom of both sides of the mounting bracket is provided with a groove for the slider 1 to slide. The connecting shaft is located in the cavity of the mounting plate.

[0011] When the movable plate moves upward, the movable plate can drive the connecting shaft to misalign with the notch on the receiving groove through the slider to prevent the wire from pulling the mounting bracket to rotate after the clamping component presses down on the wire, so as to ensure the stability of the wire when it is tensioned.

[0012] Preferably, the clamping assembly includes a pressure plate slidably connected to the upper part of the mounting bracket, two sliders mounted on both sides of the pressure plate, and a limiting member mounted on the two sliders. The pressure plate has a groove for accommodating wires, and a rubber pad is provided in the groove of the pressure plate. The two sliders are fixed to the sliding rod.

[0013] By using a rubber pad placed in the groove of the pressure plate, the friction between the wire and the pressure plate can be increased, thereby improving the tensioning effect on the wire.

[0014] Preferably, the limiting component includes a fixed rod, a second torsion spring, and a rotating plate. The fixed rod is mounted on the second slider, the rotating plate is rotatably connected to the fixed rod, and the second torsion spring is installed between the second slider and the rotating plate to drive the rotating plate to reset.

[0015] Preferably, a torsion spring is provided between the mounting base and the inner wall of the mounting frame, the mounting frame is U-shaped, and L-shaped limiting plates are installed on both sides of the mounting frame, and the rotating plate is adapted to the limiting plates.

[0016] During the tensioning of the conductor's head end, the movable plate moves upward while the rotating plate rotates to a vertical position, causing the rotating plate to engage with the limiting plate. As the conductor continues to be tensioned, the movable plate continues to move upward. At this point, the rotating plate disengages from the limiting plate and resets under the action of the second torsion spring, preparing for the pressure plate to press onto the rotating rod. When the conductor disengages from the stranding mechanism, the movable plate resets and drives the connecting shaft to align with the notch on the receiving groove, allowing the connecting shaft to pass through the notch. At this point, the conductor can pull the mounting bracket to rotate, bringing the conductor closer to the stranding equipment. During the rotation of the mounting bracket, the coordinated arrangement of the first torsion spring, the rotating rod, and the pressure plate can tighten the end of the conductor, ensuring that the end of the conductor is tensioned.

[0017] Preferably, the stranding mechanism includes a rotating component, a driving component, a connecting rod, a guiding component, a threading reel, and multiple thread-feeding components. The rotating component is rotatably connected to the base frame, the driving component is mounted on the base frame, one end of the connecting rod is mounted on the driving component, and the other end of the connecting rod passes through the rotating component, the guiding component, and the mounting plate in sequence and is connected to the threading reel. The rotating component and the guiding component are both fixed to the connecting rod, the mounting plate is slidably connected to the connecting rod, and the multiple thread-feeding components are rotatably connected in a circular array between the rotating component and the guiding component.

[0018] Preferably, the rotating assembly includes a rotating disk and a plurality of connecting cylinders. The rotating disk is mounted on a connecting rod, and the number of connecting cylinders is the same as the number of the wire feeding assembly. The connecting cylinders are mounted at one end edge of the rotating disk.

[0019] Preferably, the guiding assembly includes a guiding disk and a plurality of mounting cylinders II. The guiding disk is mounted on a connecting rod. The number of mounting cylinders II is the same as that of mounting cylinders I. The plurality of mounting cylinders II are mounted at one end edge of the guiding disk. The wire feeding assembly is rotatably connected between mounting cylinders I and mounting cylinders II.

[0020] Preferably, the guide plate has a through groove corresponding to the second mounting cylinder, and two symmetrically arranged rollers are rotatably connected inside the through groove.

[0021] By using rollers on the guide plate, friction when the wire passes through the guide plate can be reduced, thereby improving the production quality of the cable.

[0022] The beneficial effects of the present invention by adopting the above technical solution are as follows: When the first end of the conductor is tensioned, the installation mechanism is pushed to move. At this time, the installation mechanism drives the movable plate to move through the installation frame. During the movement of the movable plate, the pressure wheel moves along the inclined direction of the conductor, and at the same time, the movable plate gradually moves upward along the inclined direction of the conductor, thereby pressing the conductor so that the first end of the conductor is tensioned before stranding. When the end of the conductor is disengaged from the stranding mechanism, the movable plate resets and drives the pressing component to contact the rotating rod through the slide rod, thereby pressing the conductor so that the end of the conductor is tensioned and preventing the end of the conductor from losing tension and becoming loose.

Detailed Implementation

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 10 As shown, the cable forming machine of the present invention includes a support mechanism 10, a stranding mechanism 20, an mounting mechanism 30, and a tensioning mechanism 40. The stranding mechanism 20 is disposed on the support mechanism 10, and the mounting mechanism 30 is slidably disposed on the stranding mechanism 20 and rotatably connected to the support mechanism 10. There are multiple tensioning mechanisms 40; in this embodiment, there are three tensioning mechanisms 40 arranged in a circular array on the mounting mechanism 30 with the axis of the mounting mechanism 30 as the center. The tensioning mechanisms 40 can tension the conductors.

[0036] When stranding the conductors, the conductors on the stranding mechanism 20 are passed sequentially through the tensioning mechanism 40 and the mounting mechanism 30. Then, the mounting mechanism 30 is slid horizontally, thereby driving the tensioning mechanism 40 to move. During the movement, the tensioning mechanism 40 can gradually compress the conductors so that the conductors can maintain the same tension in the early stage of stranding. When the end of the conductor is detached from the stranding mechanism 20, the tensioning mechanism 40 can press the conductor down. At this time, the end of the conductor is tensioned when it moves, so that both the beginning and end of the conductor are tensioned during stranding, thus ensuring the quality of the cable.

[0037] like Figures 1 to 2 As shown, the support mechanism 10 includes a base frame 11, a mounting assembly 12, a first support assembly 13, a second support assembly 14, a stranding frame 15, and a hydraulic cylinder 16. The mounting assembly 12 is mounted on one side of the top of the base frame 11, and the stranding frame 15 is mounted on the other side of the top of the base frame 11. The stranding frame 15 has holes for wires to pass through, thus gathering the wires. The first support assembly 13 is mounted on the mounting assembly 12 and the stranding frame 15. The second support assembly 14 is slidably disposed between the first support assembly 13 and the stranding frame 15. The hydraulic cylinder 16 is mounted between the second support assembly 14 and the stranding frame 15, and the movable end of the hydraulic cylinder 16 is connected to the second support assembly 14. The mounting mechanism 30 is rotatably connected to the second support assembly 14.

[0038] Before the wire is stranded, the hydraulic cylinder 16 can drive the installation mechanism 30 to move through the support assembly 2 14. At the same time, the installation mechanism 30 can drive the three tensioning mechanisms 40 on it to move. During the movement, the tensioning mechanisms 40 can press the wire to tighten the beginning of the wire.

[0039] like Figures 2 to 3 As shown, the mounting assembly 12 includes a connecting frame 121, a mounting plate 122, and a retaining ring 123. The connecting frame 121 is mounted on one side of the top of the base frame 11, the mounting plate 122 is mounted on one side of the connecting frame 121, and the retaining ring 123 is mounted on the top of the other side of the connecting frame 121.

[0040] Continue to refer to Figures 2 to 3 As shown, the support assembly 13 includes a fixed frame 131 and support wheels 132. The fixed frame 131 consists of two upright plates with arc-shaped grooves on their tops and a connecting plate. The connecting plate is installed on the top of the base frame 11 and on the side near the connecting frame 121. The two upright plates with arc-shaped grooves are installed on the top sides of the connecting plate. There are multiple support wheels 132; in this embodiment, there are four support wheels 132. All four support wheels 132 are rotatably connected between the two upright plates of the fixed frame 131.

[0041] like Figures 1 to 4As shown, the second support assembly 14 includes a slide plate 141, a movable frame 142, second support wheels 143, and slide bars 144. There are two movable frames 142, each with an arc-shaped groove on its top. The two movable frames 142 are respectively mounted on the top sides of the slide plate 141. The movable end of the hydraulic cylinder 16 is mounted on the movable frame 142 near the hinge frame 15. The slide plate 141 is slidably connected to the top of the base frame 11 and located between the fixed frame 131 and the hydraulic cylinder 16. There are two slide bars 144, each mounted on the bottom sides of the slide plate 141. The base frame 11 has grooves for the slide bars 144 to slide. There are multiple second support wheels 143, the same number as the first support wheels 132. All the second support wheels 143 are rotatably connected between the two movable frames 142. The mounting mechanism 30 is located between the two movable frames 142 and in contact with the multiple second support wheels 143.

[0042] When the conductor is tensioned, the movable end of the hydraulic cylinder 16 extends and drives the movable frame 142 to move. At this time, the movable frame 142 drives the tensioning mechanism 40 to move and tension the conductor through the mounting mechanism 30.

[0043] like Figures 1 to 3 As shown, the stranding mechanism 20 includes a rotating component 21, a driving component 22, a connecting rod 23, a wire feeding component 24, a guiding component 25, and a threading reel 26. The rotating component 21 is rotatably connected to the connecting frame 121, and the driving component 22 is mounted on the mounting plate 122. One end of the connecting rod 23 is mounted on the driving component 22 and rotatably connected to the connecting frame 121. The other end of the connecting rod 23 passes through the rotating component 21, the guiding component 25, and the mounting mechanism 30 in sequence and extends to the outside of the mounting mechanism 30. The threading reel 26 is mounted on the other end of the connecting rod 23 and has holes for the wire to pass through. The rotating component 21 and the guiding component 25 are both fixed to the connecting rod 23, and the mounting mechanism 30 is slidably connected to the connecting rod 23. There are multiple wire feeding components 24. In this embodiment, the number of wire feeding components 24 is equal to the number of tensioning mechanisms 40. Multiple wire feeding components 24 are rotatably connected between the rotating component 21 and the guiding component 25 in a circular array centered on the axis of the connecting rod 23.

[0044] During wire laying, the conductor is pulled out from the laying assembly 24, then passes sequentially through the guide assembly 25, the tensioning mechanism 40, and the mounting mechanism 30 before exiting the stranding frame 15. During conductor tensioning, the hydraulic cylinder 16 moves the movable frame 142, which in turn moves the tensioning mechanism 40 via the mounting mechanism 30 to tension the conductor. During stranding, the drive assembly 22 drives the rotating assembly 21, the guide assembly 25, and the mounting mechanism 30 to rotate synchronously via the connecting rod 23 to strand the conductor.

[0045] like Figures 2 to 3 As shown, the rotating assembly 21 includes a rotating disk 211, a mounting cylinder 212, and a connecting cylinder 213. The rotating disk 211 is mounted on the outside of the connecting rod 23. The mounting cylinder 212 is mounted on one end of the rotating disk 211 and rotatably connected to the inside of the fixing ring 123. The number of connecting cylinders 213 is the same as the number of wire feeding assemblies 24. The connecting cylinders 213 are mounted on the edge of the other end of the rotating disk 211.

[0046] Continue to refer to Figures 2 to 3 As shown, the drive assembly 22 includes a motor 221, a first gear 222, and a second gear 223. The motor 221 is mounted on the top of the mounting plate 122, and the first gear 222 is mounted on the drive shaft of the motor 221. The second gear 223 is located on top of the first gear 222 and meshes with the first gear 222. The second gear 223 is mounted on the outer side of one end of the connecting rod 23.

[0047] When motor 221 drives gear 223 to rotate via gear 1 222, gear 223 drives rotating component 21, guide component 25 and mounting mechanism 30 to rotate synchronously via connecting rod 23.

[0048] like Figures 2 to 3 and Figure 5 As shown, the guide assembly 25 includes a guide plate 251 and a mounting cylinder 252. The guide plate 251 is located in the fixing frame 131 and contacts the support wheel 132. The mounting cylinder 252 is installed at one end edge of the guide plate 251, and the number of mounting cylinders 252 is the same as that of the mounting cylinder 212. The guide plate 251 has a through groove 253 corresponding to the mounting cylinder 252 for the wire to pass through. Two symmetrically arranged rollers 254 are rotatably connected inside the through groove 253 to reduce friction when the wire passes through the through groove 253.

[0049] like Figures 2 to 3 As shown, the wire feeding assembly 24 includes a rotating frame 241 and a wire feeding reel 242. The two ends of the rotating frame 241 are rotatably connected to mounting cylinder 1 212 and mounting cylinder 252, respectively. The end of the rotating frame 241 connected to mounting cylinder 252 has a hole for the wire to pass through. The wire feeding reel 242 is rotatably connected to the inside of the rotating frame 241 to feed the wire.

[0050] During the wire laying process, one end of the wire is pulled out from the wire laying reel 242, and then the end of the wire is allowed to enter the through groove 253 through the mounting cylinder 252. The end of the wire that has entered the through groove 253 continues to move forward and passes through the roller 254, the tensioning mechanism 40 and the mounting mechanism 30 in sequence before being twisted in the twisting frame 15.

[0051] like Figures 1 to 4 and Figures 6 to 7As shown, the mounting mechanism 30 includes a mounting plate 31 and receiving slots 32. The mounting plate 31 has an internal cavity and is located between two movable frames 142 and in contact with the support wheel 143. There are multiple receiving slots 32, and their number is equal to the number of tensioning mechanisms 40. The multiple tensioning mechanisms 40 are located in the multiple receiving slots 32 respectively. The multiple receiving slots 32 are arranged in a circular array around the axis of the mounting plate 31 at one end of the mounting plate 31. A notch 33 is opened at the bottom of the side of the receiving slot 32 opposite to the wire threading plate 26.

[0052] like Figure 1 and Figure 6 As shown, the tensioning mechanism 40 includes a rotating assembly 41, a pressing assembly 42, and a clamping assembly 43. The rotating assembly 41 is disposed in the receiving groove 32, the pressing assembly 42 is elastically slidably disposed inside the lower part of the rotating assembly 41, and the clamping assembly 43 is elastically slidably disposed inside the upper part of the rotating assembly 41. The pressing assembly 42 and the clamping assembly 43 are connected.

[0053] like Figures 6 to 10 As shown, the rotating assembly 41 includes a mounting bracket 411, a rotating rod 412, a mounting rod 413, a mounting base 414, a protruding plate 416, and a limiting plate 417. The mounting bracket 411 is U-shaped and is installed on the outer sides of both ends of the mounting rod 413. The mounting base 414 is rotatably connected to the middle of the outer side of the mounting rod 413 and is installed on the inner bottom wall of the receiving groove 32. Torsion springs 415 connected to the inner wall of the mounting bracket 411 are installed on both sides of the mounting base 414. The rotating rod 412 is rotatably connected to the upper interior of the mounting bracket 411. The pressing assembly 43 is slidably disposed inside the mounting bracket 411 and located above the rotating rod 412. The wire pressing assembly 42 is slidably disposed inside the lower interior of the mounting bracket 411.

[0054] There are two protruding plates 416 and two limiting plates 417. The two protruding plates 416 are respectively installed on both sides of the mounting frame 411, and the two limiting plates 417 are respectively installed on both sides of the mounting frame 411 and located above the protruding plates 416. The limiting plates 417 are L-shaped.

[0055] like Figures 6 to 8 As shown, the wire pressing assembly 42 includes a movable plate 421, a wire guide groove 422, a wire pressing wheel 423, a slider 424, a connecting shaft 425, and a sliding rod 426. The movable plate 421 is inclinedly disposed inside the mounting bracket 411, the wire guide groove 422 is formed at one end of the movable plate 421, and the wire pressing wheel 423 is rotatably connected inside the wire guide groove 422.

[0056] There are two sliders 424, two connecting shafts 425, and two sliding rods 426. The two sliders 424 are respectively installed on the bottom sides of the movable plate 421, and grooves for sliding the sliders 424 are provided on the bottom sides of the mounting bracket 411. The two connecting shafts 425 are respectively installed on one side of the two sliders 424, and are located in the cavity of the mounting plate 31. The bottom ends of the two sliding rods 426 are respectively installed on the tops of the two sliders 424, and the top ends of the sliding rods 426 pass through the protrusion plate 416 and are connected to the clamping assembly 43. A spring 427 is installed between the sliders 424 and the protrusion plate 416 to drive the movable plate 421 to return to its original position.

[0057] When the wire is tensioned, the end of the guide wire passes through the wire groove 422 of the movable plate 421 and contacts the wire pressing wheel 423. Then, the pressing assembly 43 is pulled upward and the limiting plate 417 prevents the pressing assembly 43 from resetting. At this time, the end of the wire passes between the rotating rod 412 and the pressing assembly 43, so that the wire between the guide plate 251 and the mounting plate 31 is in an inclined state. Finally, the end of the wire passes through the receiving groove 32, the wire threading plate 26 and the stranding frame 15 in sequence.

[0058] After the conductor is guided, the hydraulic cylinder 16 is activated. The hydraulic cylinder 16 drives the mounting plate 31 to move via the movable frame 142. The mounting plate 31 drives the movable plate 421 to move via the mounting frame 411. During the movement of the movable plate 421, the pressure roller 423 moves along the inclined direction of the conductor, causing the movable plate 421 to gradually move upward. At this time, under the action of the spring 427, the pressure roller 423 can press the conductor tightly.

[0059] like Figures 6 to 10 As shown, the clamping assembly 43 includes a pressure plate 431, a second slider 432, and a limiting member. The pressure plate 431 is slidably connected inside the mounting bracket 411 and located above the rotating rod 412. A groove for accommodating the wire is formed at the bottom of the pressure plate 431, and a rubber pad is placed in the groove to increase the resistance when the wire passes through the pressure plate 431. There are two second sliders 432 and two limiting members. The two second sliders 432 are respectively installed on both sides of the pressure plate 431. Grooves for sliding the second sliders 432 are formed on the top of both sides of the mounting bracket 411. The bottom of the second slider 432 is fixed to the top of the sliding rod 426. The two limiting members are respectively installed on one side of the two second sliders 432, and the limiting members are adapted to the limiting plate 417.

[0060] The limiting components include a fixed rod 433, a second torsion spring 434, and a rotating plate 435. The fixed rod 433 is installed on one side of the second slider 432, and the rotating plate 435 is rotatably connected to one end of the fixed rod 433. The second torsion spring 434 is sleeved on the outside of the fixed rod 433 and installed between the second slider 432 and the rotating plate 435 to drive the rotating plate 435 to reset.

[0061] When the guide wire passes through the mounting bracket 411, the movable plate 421 is first pulled upward. At this time, the movable plate 421 drives the pressure plate 431 to move upward via the slide rod 426 on the slider 424. After the pressure plate 431 moves upward, it moves the rotating plate 435 into the limiting plate 417. At this time, the limiting plate 417 can prevent the rotating plate 435 from resetting, thereby preventing the pressure plate 431 from resetting, making it easier for the wire to pass between the rotating rod 412 and the pressure plate 431. During the upward movement of the slider 424, it also drives the connecting shaft 425 to move upward in the cavity of the mounting plate 31, causing the connecting shaft 425 to be misaligned with the notch 33 on the mounting plate 31.

[0062] During the tensioning process of the conductor, the mounting plate 31 is moved first, and the mounting plate 31 drives the movable plate 421 to move via the mounting bracket 411. As the movable plate 421 moves, the pressure roller 423 moves along the inclined direction of the conductor, thereby pressing the conductor firmly. During the conductor pressing process, the movable plate 421 drives the pressure plate 431 on the slide rod 426 to continue moving upward via the slider 1 424. Simultaneously, the pressure plate 431 drives the rotating plate 435 to move out of the limiting plate 417 via the slider 2 432. When the rotating plate 435 disengages from the limiting plate 417, the torsion spring 2 434 can drive the rotating plate 435 to reset, causing the rotating plate 435 to rotate to a horizontal position.

[0063] When the end of the wire detaches from the wire feeding reel 242, the spring 427 causes the movable plate 421 to reset. Simultaneously, the movable plate 421, via the slider 424, causes the pressure plate 431 on the slide rod 426 to reset, clamping the wire between the pressure plate 431 and the rotating rod 412. During the reset process, the slider 424 also causes the connecting shaft 425 to move downwards, aligning it with the notch 33 on the mounting plate 31. As the wire continues to move, the action of the wire and the pressure plate 431 pulls the mounting bracket 411 to rotate around the mounting rod 413 and approach the wire threading reel 26. Simultaneously, the torsion spring 415 tightens the wire. As the mounting bracket 411 approaches the wire threading reel 26, the distance the wire travels through the mounting bracket 411 into the wire threading reel 26 is shortened, allowing the wire to pass through the reel 26 more smoothly and reducing friction between the wire and the outside environment.

[0064] Working principle: Before stranding the wires, one end of the wire is pulled out from the wire release reel 242, and then the end of the wire enters the through groove 253 through the mounting cylinder 252. The end of the wire in the through groove 253 continues to move forward and passes through the roller 254, the movable plate 421, the receiving groove 32 and the wire threading reel 26 in sequence, and finally exits from the stranding frame 15. When the wire passes through the receiving groove 32, the movable plate 421 is pulled upward. At this time, the movable plate 421 drives the pressure plate 431 to move upward through the sliding rod 426 on the slider 424. After the pressure plate 431 moves upward, the rotating plate 435 is moved into the limiting plate 417. At this time, the limiting plate 417 can prevent the rotating plate 435 from resetting, thereby preventing the pressure plate 431 from resetting, so that the wire can pass between the rotating rod 412 and the pressure plate 431. As the slider 424 moves upward, it also drives the connecting shaft 425 to move upward in the cavity of the mounting plate 31, causing the connecting shaft 425 to be misaligned with the notch 33 on the mounting plate 31.

[0065] Then, hydraulic cylinder 16 is activated. Hydraulic cylinder 16 drives mounting plate 31 to move via movable frame 142. Mounting plate 31 drives movable plate 421 to move via mounting frame 411. During the movement of movable plate 421, pressure roller 423 moves along the inclined direction of the wire, thereby pressing the wire. During the pressing of the wire, movable plate 421 drives pressure plate 431 on slide rod 426 to continue moving upward via slider 1 424. At the same time, pressure plate 431 drives rotating plate 435 to move out of limit plate 417 via slider 2 432. When rotating plate 435 disengages from limit plate 417, under the action of torsion spring 2 434, rotating plate 435 can be reset, causing rotating plate 435 to rotate to a horizontal state. At this time, motor 221 is started to begin twisting the wire.

[0066] When the end of the wire detaches from the wire feeding reel 242, the spring 427 causes the movable plate 421 to reset. Simultaneously, the movable plate 421, via the slider 424, causes the pressure plate 431 on the slide rod 426 to reset, clamping the wire between the pressure plate 431 and the rotating rod 412. During the reset process, the slider 424 also causes the connecting shaft 425 to move downwards, aligning it with the notch 33 on the mounting plate 31. As the wire continues to move, the action of the wire and the pressure plate 431 pulls the mounting bracket 411 to rotate around the mounting rod 413 and approach the wire threading reel 26. Simultaneously, the torsion spring 415 tightens the wire. As the mounting bracket 411 approaches the wire threading reel 26, the distance the wire travels through the mounting bracket 411 into the wire threading reel 26 is shortened, allowing the wire to pass through the reel 26 more smoothly and reducing friction between the wire and the outside environment.
