Description

Technical Field

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

[0002] The stranding device in cable production is one of the most important pieces of equipment in the cable manufacturing process. It is mainly used to strand multiple conductive cores together according to specific rules and requirements to form cables with specific structural and performance requirements.

[0003] Chinese patent application CN202410118596.9 discloses a stranding device and its usage method for cable production. It includes a base, a motor mounted on the base, a rotating frame rotatably connected to the base, a feeding shaft rotatably connected to the rotating frame, a transfer frame rotatably connected to the base, a synchronous shaft fixed to the transfer frame, a synchronous frame fixed to the synchronous shaft, a clamping frame fixed to the base, a rotating shell rotatably connected to the base, a first slider slidably connected inside the rotating shell, a support leg rotatably connected to the first slider, and a first intermediate rotating wheel rotatably connected to the support leg.

[0004] This invention pre-deforms the auxiliary wire before stranding by setting two sets of first intermediate rotating wheels and adjusting the relative rotation angle between the two sets of first intermediate rotating wheels. This prevents insufficient deformation when the auxiliary wire is directly stranded onto the main wire, which would result in loose stranding between the auxiliary wires. However, in traditional stranding mechanisms, when stranding metal conductors, multiple metal wire spools are set horizontally on one side of the stranding mechanism. When the metal conductors released from the metal wire spools pass through the feed holes, the metal conductors between the feed holes and the metal wire spools will swing during the release process due to the horizontal setting of the multiple metal wire spools. The distance between the metal conductors between the feed holes and the metal wire spools is relatively close, which can cause adjacent metal conductors to become entangled. This not only affects the production quality of the cable by the stranding mechanism, but also requires untangling the entangled wires when they become entangled, thus affecting the production efficiency of the cable by the stranding mechanism. Summary of the Invention

[0005] The purpose of this invention is to provide a stranding device for cable production, in order to solve the problems mentioned in the background art above:

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A stranding device for cable production includes a base, with a rotating ring and a turntable rotatably connected to both ends of the base. Multiple rotatable frames are arranged inside the rotating ring. Each rotating frame has multiple placement slots on its surface. Support plates corresponding to the positions of the placement slots are fixedly mounted on the surface of each rotating frame. A shaft is provided on the surface of each support plate, and a metal wire spool is placed on the surface of the shaft. The metal wire spool is rotatably connected to the support plate via the shaft and is located inside the placement slot. Multiple fixed platforms are fixedly mounted on the bottom surface of the rotating frame, and the multiple fixed platforms are connected to the multiple placement slots. The slots are staggered, and each of the fixed platforms has a slot inside. The bottom surface of each fixed platform has an outer slot communicating with the slot. A fixed frame is fixedly installed inside the slot. A matching slide is slidably connected inside the fixed frame. A first spring is elastically connected between the slide and the fixed frame. A rotating rod is rotatably connected to the bottom inner side of the slide. A rotating wheel that can follow the rotation is provided on the surface of the rotating rod. A number of through-holes for wiring are provided on the surface of the turntable. A clamping frame is fixedly installed on one side of the turntable. The clamping frame corresponds to the center position of the turntable.

[0008] By adopting the above technical solution, multiple rotating frames pull out the metal wires from the surfaces of multiple metal reels. Each metal wire passes through the surface of the rotating wheel one by one, and then passes through its corresponding cable routing hole. The rotation of the rotating frames causes the metal reels to be on different horizontal planes, achieving layering of the metal wires on the rotating frames. After multiple metal wires pass through their respective cable routing holes, they are all placed into the clamping frame. Compared with the traditional method of placing metal reels horizontally, the rotation of the rotating frames, which causes the metal reels to be on different horizontal planes and achieves layering of the metal wires on the rotating frames, solves the problem of cable routing during the cable production process. The problem of metal wire entanglement between the wire hole and the metal spool improves the quality of cable production by the stranding device, thereby increasing the production efficiency of the stranding mechanism. During the stranding process, when the metal wire suddenly tightens, the roller is squeezed, causing the rotating rod to move and the slide to move into the fixed frame, squeezing the first spring. When the metal wire suddenly loosens, the slide moves under the action of the first spring, causing the rotating rod and roller to move and act on the surface of the metal wire. To prevent the metal wire from suddenly tightening or loosening, the tension of the metal wire during the conveying process is adjusted by setting the rotating rod, roller, slide, and first spring, thus achieving smooth conveying of the metal wire.

[0009] Preferably, the cable routing holes are used for the metal conductors of the manufactured cable to pass through. The cable routing holes are divided into multiple groups, and any group of cable routing holes is arranged sequentially towards the center of the turntable. A fixing ring is fixedly installed on the inner side of the rotating ring. A matching sliding column is slidably connected inside the fixing ring. The surface of the fixing ring is provided with a sliding groove. The number of sliding grooves is the same as the number of rotating frames, and their positions are corresponding. A toothed plate is slidably connected inside any one of the sliding grooves. The toothed plate is fixedly connected to the surface of the sliding column. Multiple fixing columns are fixedly connected between the fixing ring and the rotating ring.

[0010] By adopting the above technical solution, the rotation of the rotating frame causes the various metal wire reels to be on different horizontal planes. Multiple metal wire reels achieve layering of metal wires on the rotating frame. After multiple metal wires pass through their respective cable routing holes, they are all placed into the clamping frame. Compared with the traditional method of placing metal wire reels on the same horizontal plane, the rotation of the rotating frame causes the various metal wire reels to be on different horizontal planes. Multiple metal wire reels achieve layering of metal wires on the rotating frame. In the cable production process, the problem of metal wire entanglement between the cable routing holes and the metal wire reels is solved.

[0011] Preferably, multiple sets of fixing plates are fixedly installed on the surface of the rotating ring, with two fixing plates in each set. A rotating shaft is rotatably connected between the two fixing plates. A gear that meshes with a toothed plate is concentrically fixedly installed on the surface of the rotating shaft. The gear is rotatably connected to the fixing plate through the rotating shaft. A fixing block is fixedly installed on the surface of the rotating shaft, located on both sides of the gear. The surfaces of both fixing blocks are fixedly connected to the rotating frame.

[0012] By adopting the above technical solution, the gear meshes with the toothed plate, preventing the rotating frame from resetting under its own weight after the rotating frame has finished rotating.

[0013] Preferably, a first bracket is fixedly installed on one side surface of the base, a rotating disk is rotatably connected inside the first bracket, an electric telescopic rod is fixedly installed on the surface of the rotating disk, and the telescopic end of the electric telescopic rod is fixedly connected to a sliding column.

[0014] By adopting the above technical solution, the electric telescopic rod provides power for the rotation of the rotating frame.

[0015] Preferably, a second bracket is fixedly installed on the other side surface of the base, the clamping frame is fixedly installed through the surface of the second bracket, multiple connecting frames are fixedly installed between the rotating ring and the turntable, a slide cylinder is fixedly installed on the inner side of the turntable, a slide rod is movably connected inside the slide cylinder, and one end of the slide rod is fixedly connected to the inner surface of the slide column.

[0016] Preferably, a gear ring is fixedly installed on the outer surface of the rotating ring, a mounting bracket is fixedly installed on one side surface of the base, the mounting bracket is located on one side of the first bracket, a gear disc that meshes with the gear ring is rotatably connected to the inner side of the mounting bracket, a motor is fixedly installed on the surface of the mounting bracket, and the output end of the motor is fixedly connected to the gear disc.

[0017] By adopting the above technical solution, the motor is configured to provide power for the synchronous rotation of the rotating ring and turntable, as well as the synchronous rotation of the metal wire reel and the cable routing hole.

[0018] Preferably, the inside of the rotating wheel is provided with multiple slots, and each slot is slidably connected to a matching arc-shaped seat. The surface of the arc-shaped seat is provided with a conveying groove for conveying metal wires. A second spring is elastically connected between the arc-shaped seat and the slot. One end of the second spring is fixedly connected to the arc-shaped seat, and the other end of the second spring is fixedly connected to the inner wall of the slot.

[0019] By adopting the above technical solution, during the process of conveying stranded metal wire, as the metal wire reel continuously feeds the metal wire, the position of the metal wire winding on the surface of the metal wire reel changes. At this time, the metal wire will move with the conveying groove and the arc-shaped seat, causing the wheel to slide on the surface of the rotating rod, ensuring that the position of the wheel and the metal wire reel are always aligned, thus further ensuring the smooth conveying of the metal wire. At the same time, under the action of the arc-shaped seat and the second spring, the tension of the metal wire is adjusted during the conveying process, further ensuring the stable conveying of the metal wire.

[0020] Preferably, the surface of the rotating rod is provided with a movable groove, and the inner side of the rotating wheel is fixedly installed with a plug that matches the movable groove. The plug can slide inside the movable groove. With the plug and the movable groove matching each other, the rotating wheel can rotate and slide on the surface of the rotating rod.

[0021] Preferably, one end of the insert shaft is threaded with a limit block, the surface of the rotating frame is provided with a rotatable locking rod, and multiple stacking racks for storing the rotating frame are fixedly installed on the inner side of the rotating ring. The stacking racks and the rotating ring are fixedly connected with a reinforcing rod. The surface of any stacking rack is provided with a number of semi-circular grooves equal to the number of placement grooves. When the rotating frame is stored inside the stacking rack, the placement grooves and semi-circular grooves are in the same position.

[0022] By adopting the above technical solution, the clamp is used for axial positioning of the surface of the metal wire reel insert shaft, and the clamp is rotatably connected to the insert shaft. The clamp will not affect the rotation of the insert shaft or the rotation of the metal wire reel.

[0023] A method for stranding wire in cable production, comprising the following steps:

[0024] S1: In the initial state, the rotating frame is stored inside the stacking frame. At this time, the metal wire spool is inserted into the inside of the insert shaft through the semi-circular groove. Then, the limiting block is screwed onto the end of the insert shaft. Finally, the locking rod is rotated into the groove on the surface of the insert shaft. After the metal wire spools are inserted into the insert shaft in sequence, the motor servo rotates to make the gear ring rotate, thereby making the rotating ring rotate and the turntable servo rotate, so that the next set of metal wire spools is inserted into the surface of the insert shaft.

[0025] S2: After the metal wire reels are completely placed, the electric telescopic rod extends and moves the sliding column. The sliding column moves the toothed plate to slide in the slide groove. The movement of the toothed plate causes the gear to rotate, which in turn rotates the shaft, thus causing multiple rotating frames to rotate out from inside the stacking frame. After the rotating frames have rotated, the metal wires on the surface of multiple metal wire reels are pulled out. Each metal wire passes through the surface of the rotating wheel one by one. When the metal wire passes through the surface of the rotating wheel, the metal wire will be stuck inside the conveying groove. Then the metal wire passes through its corresponding wiring hole. The rotation of the rotating frame makes the metal wire reels not on the same horizontal plane. Multiple metal wire reels achieve layering of metal wires on the rotating frame. After multiple metal wires pass through their corresponding wiring holes, multiple metal wires are put into the inside of the clamping frame.

[0026] S3: The motor continuously rotates, causing the gear disc to rotate, which in turn causes the gear ring to rotate, along with the rotating ring and the turntable. The rotating ring rotates, causing the fixed plate to rotate, which in turn causes the rotating frame to follow the rotating ring and rotate the metal wire reel. The rotating ring also causes the fixed ring to rotate, which in turn causes the sliding column to rotate, which in turn causes the electric telescopic rod to rotate. This causes the rotating disk to rotate inside the first bracket. During the cable production process, the rotating ring and the turntable rotate synchronously, causing the metal wire reel and the cable routing hole to rotate synchronously. In addition, multiple metal wire reels on the rotating frame achieve layering of the metal wires. During the cable production process, the problem of metal wire tangling is avoided. Finally, the metal wires are twisted through the clamping frame.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1) When this stranding device for cable production is in use, compared with the traditional metal reels placed horizontally, the rotating frame makes the metal reels not on the same horizontal plane. Multiple metal reels achieve layering of metal wires on the rotating frame. In the cable production process, it solves the problem of metal wire entanglement between the cable routing hole and the metal reels, improves the quality of cable production by the stranding device, and thus improves the production efficiency of the stranding mechanism for cables.

[0029] 2) When the stranding device used in cable production is in use, during the process of conveying stranded metal wires, if the metal wires suddenly become tense, the rotating wheel will be squeezed, causing the rotating rod to move and the slide to move into the fixed frame to squeeze the first spring. If the metal wires suddenly become slack, the slide will move under the action of the first spring, causing the rotating rod and the rotating wheel to move and act on the surface of the metal wires. In order to prevent the metal wires from suddenly becoming tense or slack, the tension of the metal wires during the conveying process is adjusted by setting the rotating rod, rotating wheel, slide and the first spring to achieve smooth conveying of the metal wires.

[0030] 3) When the stranding device used for cable production is in use, during the process of feeding the stranded metal wire, the position of the metal wire wrapped on the surface of the metal wire reel changes as the metal wire reel continuously feeds the metal wire. At this time, the metal wire will move with the conveying groove and the arc-shaped seat, causing the wheel to slide on the surface of the rotating rod, always ensuring that the position of the wheel and the metal wire reel correspond, further ensuring the smooth feeding of the metal wire. At the same time, under the action of the arc-shaped seat and the second spring, the tension of the metal wire is adjusted during the feeding process, further ensuring the stable feeding of the metal wire.

Detailed Implementation

[0048] Example 1: Please refer to Figure 1 - Figure 16A stranding device for cable production includes a base 1, with a rotating ring 2 and a turntable 3 rotatably connected to both ends of the base 1. Multiple rotatable frames 4 are arranged inside the rotating ring 2. The rotation of the frames 4 causes the metal wire spools 8 to be out of parallel planes, achieving layering of metal wires on the frames 4. Multiple placement slots 5 are formed on the surface of any one of the frames 4. Support plates 6 corresponding to the positions of the placement slots 5 are fixedly installed on the surface of the frames 4. A shaft 7 is provided on the surface of any one of the support plates 6, and metal wire spools 8 are placed on the surface of the shaft 7. The metal wire spools 8 are rotatably connected to the support plates 6 via the shafts 7. The metal wire spools 8 are located inside the placement slots 5. When the frame 4 is stored inside the stacking rack 47, ensure that the metal wire reel 8 can be removed and installed. Multiple fixed platforms 9 are fixedly installed on the bottom surface of the rotating frame 4. These fixed platforms 9 and multiple placement slots 5 are arranged alternately. Each fixed platform 9 has a slot 10 inside, and the bottom surface of each fixed platform 9 has an outer slot 11 communicating with the slot 10. A fixed frame 12 is fixedly installed inside the slot 10. A matching slide 13 is slidably connected inside the fixed frame 12. A first spring 14 elastically connects the slide 13 and the fixed frame 12. To prevent sudden tension or slack in the metal wire, a rotating rod 15, a rotating wheel 16, and a slide 13 are used. The first spring 14 adjusts the tension of the metal wire during transport, ensuring smooth transport. A rotating rod 15 is rotatably connected to the inner bottom of the slide 13. A rotating wheel 16, which rotates with the rod 15, is mounted on its surface. The wheel 16 can rotate and slide on the surface of the rod 15. Several through-holes 17 are provided on the surface of the turntable 3. A clamping frame 18 is fixedly installed on one side of the turntable 3, corresponding to the center of the turntable 3. By rotating multiple rotating frames 4, the metal wires on the surfaces of multiple metal wire reels 8 are pulled out. Each metal wire passes through the surface of the rotating wheel 16 one by one, and then passes through its corresponding cable routing hole 17. The rotation of the rotating frame 4 causes the various metal wire reels 8 to be on different horizontal planes. Multiple metal wire reels 8 achieve layering of metal wires on the rotating frame 4. After multiple metal wires pass through their respective cable routing holes 17, they are all placed into the clamping frame 18. Compared with the traditional method of placing metal wire reels on the same horizontal plane, the rotation of the rotating frame 4 causes the various metal wire reels 8 to be on different horizontal planes. Multiple metal wire reels 8 achieve layering of metal wires on the rotating frame 4. In the cable production process, this solves the problem of metal wire entanglement between the cable routing holes 17 and the metal wire reels 8, improves the quality of cable production by the stranding device, and thus improves the production efficiency of the stranding mechanism for cables.During the conveying of stranded metal wire, when the metal wire suddenly tightens, the rotating wheel 16 is compressed, causing the rotating rod 15 to move, pulling the slide 13 into the fixed frame 12 and compressing the first spring 14. When the metal wire suddenly loosens, the slide 13, under the action of the first spring 14, moves, causing the rotating rod 15 and the rotating wheel 16 to act on the surface of the metal wire. To prevent sudden tightening or loosening of the metal wire, the tension of the metal wire during conveying is adjusted by setting up the rotating rod 15, rotating wheel 16, slide 13, and first spring 14, thus achieving smooth conveying of the metal wire.

[0049] The cable routing holes 17 are used for the metal conductors of the cables to pass through. Multiple groups of cable routing holes 17 are arranged sequentially towards the center of the turntable 3. A fixed ring 19 is fixedly installed inside the rotating ring 2. A matching sliding post 20 is slidably connected inside the fixed ring 19. The surface of the fixed ring 19 has grooves 21, the number of which is the same as the number of rotating frames 4, and their positions correspond. A toothed plate 22 is slidably connected inside each groove 21. The toothed plate 22 is fixedly connected to the surface of the sliding post 20. Multiple fixed rings are fixedly connected to both the fixed ring 19 and the rotating ring 2. The rotation of the fixed column 38 and the rotating frame 4 causes the various metal wire reels 8 to be on different horizontal planes. Multiple metal wire reels 8 achieve layering of metal wires on the rotating frame 4. After multiple metal wires pass through their respective cable routing holes 17, they are all placed into the clamping frame 18. Compared with the traditional method of placing metal wire reels on the same horizontal plane, the rotation of the rotating frame 4 causes the various metal wire reels 8 to be on different horizontal planes. Multiple metal wire reels 8 achieve layering of metal wires on the rotating frame 4. In the cable production process, the problem of metal wire entanglement between the cable routing holes 17 and the metal wire reels 8 is solved.

[0050] Multiple sets of fixing plates 23 are fixedly installed on the surface of the rotating ring 2. Each set of fixing plates 23 consists of two plates, and a rotating shaft 24 is rotatably connected between the two fixing plates 23. A gear 25 that meshes with the toothed plate 22 is fixedly installed on the surface of the rotating shaft 24. The gear 25 is rotatably connected to the fixing plate 23 through the rotating shaft 24. Fixing blocks 26 are fixedly installed on the surface of the rotating shaft 24. The fixing blocks 26 are located on both sides of the gear 25. The surfaces of both fixing blocks 26 are fixedly connected to the rotating frame 4. The gear 25 meshes with the toothed plate 22. After the rotating frame 4 has rotated, it prevents the rotating frame 4 from resetting under its own weight.

[0051] A first bracket 27 is fixedly installed on one side surface of the base 1. A rotating disk 36 is rotatably connected inside the first bracket 27. An electric telescopic rod 37 is fixedly installed on the surface of the rotating disk 36. The telescopic end of the electric telescopic rod 37 is fixedly connected to the sliding column 20. The electric telescopic rod 37 is a conventional electric control push rod in the prior art. The setting of the electric telescopic rod 37 provides power for the rotation of the rotating frame 4.

[0052] A second bracket 28 is fixedly installed on the other side surface of the base 1. A clamping frame 18 is fixedly installed through the surface of the second bracket 28. The clamping frame 18 is a conventional clamping frame 18 in the prior art. The clamping frame 18 is used to twist the metal wires to realize the production of cables. Multiple connecting frames 29 are fixedly installed between the rotating ring 2 and the turntable 3. A slide cylinder 30 is fixedly installed on the inner side of the turntable 3. A slide rod 31 is movably connected inside the slide cylinder 30. One end of the slide rod 31 is fixedly connected to the inner surface of the slide column 20.

[0053] A gear ring 32 is fixedly mounted on the outer surface of the rotating ring 2. A mounting bracket 33 is fixedly mounted on one side surface of the base 1. The mounting bracket 33 is located on one side of the first bracket 27. A gear disk 34 that meshes with the gear ring 32 is rotatably connected to the inner side of the mounting bracket 33. A motor 35 is fixedly mounted on the surface of the mounting bracket 33. The motor 35 is a conventional electric motor in the prior art. The motor 35 can rotate servo or rotate continuously. The rotation of the motor 35 is controlled by an existing programmable controller. The output end of the motor 35 is fixedly connected to the gear disk 34.

[0054] One end of the insert shaft 7 is threadedly connected to a limiting block 45. The surface of the rotating frame 4 is provided with a rotatable locking rod 46. Multiple stacking racks 47 for storing the rotating frame 4 are fixedly installed on the inner side of the rotating ring 2. The stacking racks 47 and the rotating ring 2 are fixedly connected by a reinforcing rod 48. The surface of any stacking rack 47 is provided with the same number of semi-circular grooves 49 as the placement grooves 5. When the rotating frame 4 is stored inside the stacking rack 47, the placement grooves 5 and the semi-circular grooves 49 are in the same position. The locking rod 46 is used to limit the axial movement of the surface of the insert shaft 7 of the metal wire reel 8. The locking rod 46 is rotatably connected to the insert shaft 7. The locking rod 46 will not affect the rotation of the insert shaft 7 and the rotation of the metal wire reel 8.

[0055] The usage steps of this invention are as follows: In the initial state of use, the stranding device for cable production has the rotating frame 4 housed inside the stacking frame 47. At this time, the metal wire spool 8 is inserted into the insert shaft 7 through the semi-circular groove 49. Then, the limiting block 45 is screwed onto the end of the insert shaft 7. Finally, the locking rod 46 is rotated into the groove on the surface of the insert shaft 7 (the locking rod 46 is used for axial positioning of the metal wire spool 8 on the surface of the insert shaft 7, and the locking rod 46 is rotatably connected to the insert shaft 7; the locking rod 46 will not affect the rotation of the insert shaft 7 or the rotation of the metal wire spool 8). After the metal wire spools 8 are sequentially inserted into the insert shaft 7, the motor 35 rotates servo-drivenly, causing the gear ring 32 to rotate, thereby causing the rotating ring 2 to rotate, which in turn causes the rotating disk 3 to rotate servo-drivenly. The next set of metal wire spools 8 is inserted into the surface of the insert shaft 7. When the metal wire spools 8 are completely placed... After completion, the electric telescopic rod 37 extends, causing the sliding column 20 to move. The sliding column 20 moves, causing the toothed plate 22 to slide in the sliding groove 21. The movement of the toothed plate 22 causes the gear 25 to rotate, which in turn rotates the rotating shaft 24, thus causing multiple rotating frames 4 to rotate out from inside the stacking frame 47. During the rotation of the rotating frame 4, the sliding frame 13 is no longer squeezed by the bottom surface inside the stacking frame 47. At this time, the sliding frame 13 extends under the action of the first spring 14. The movement of the sliding frame 13 causes the rotating rod 15 and the rotating wheel 16 to move. After the rotating frame 4 has finished rotating, it pulls out the metal wires from the surface of multiple metal wire reels 8. Each metal wire passes through the surface of the rotating wheel 16 one by one. When the metal wire passes through the surface of the rotating wheel 16, the metal wire will be stuck inside the conveying groove 41. Then the metal wire will exit from its corresponding row. The wire hole 17 passes through the rotating frame 4, causing the various metal wire reels 8 to be on different horizontal planes. Multiple metal wire reels 8 achieve layering of metal wires on the rotating frame 4. After multiple metal wires pass through their corresponding wiring holes 17, they are all placed into the clamping frame 18. At this time, the motor 35 continuously rotates, causing the gear disc 34 to rotate, which in turn causes the gear ring 32 to rotate, driving the rotating ring 2 and the rotating plate 3 to rotate. The rotating ring 2 rotates, causing the fixing plate 23 to rotate, thus causing the rotating frame 4 to follow the rotating ring 2 and rotate the metal wire reels 8. The rotating ring 2 also causes the fixing ring 19 to rotate, causing the sliding column 20 to rotate, driving the electric telescopic rod 37 to rotate, which in turn causes the rotating plate 36 to rotate inside the first bracket 27. During the cable production process, the rotating ring 2 and the rotating plate 36 rotate... The rotating disc 3 synchronously rotates the metal wire discs 8 and the cable routing holes 17. Furthermore, the multiple metal wire discs 8 on the rotating frame 4 achieve layering of the metal wires, preventing the metal wires from tangling during cable production. Finally, the metal wires are twisted through the clamping frame 18. This scheme, through the rotation of multiple rotating frames 4, pulls out the metal wires from the surfaces of multiple metal wire discs 8. Each metal wire passes through the surface of the rotating wheel 16 one by one, and then passes through its corresponding cable routing hole 17. The rotation of the rotating frame 4 causes the metal wire discs 8 to be on different horizontal planes, achieving layering of the metal wires on the rotating frame 4. After multiple metal wires pass through their respective cable routing holes 17, they are all placed into the clamping frame 18.Compared to traditional horizontal placement of metal reels, the rotating frame 4 rotates, causing the metal reels 8 to be on different horizontal planes. Multiple metal reels 8 are layered on the rotating frame 4, solving the problem of metal wire entanglement between the cable routing hole 17 and the metal reels 8 during cable production. This improves the quality of cable production by the stranding device and thus increases the production efficiency of the stranding mechanism. During the stranding process, when the metal wire suddenly tightens, the rotating wheel 16 is compressed, causing the rotating rod 15 to move, carrying the slide 13 into the fixed frame 12 and compressing the first spring 14. When the metal wire suddenly loosens, the slide 13, under the action of the first spring 14, moves, carrying the rotating rod 15 and the rotating wheel 16, acting on the surface of the metal wire. To prevent sudden tightening or loosening of the metal wire, the tension of the metal wire during transport is adjusted by setting the rotating rod 15, rotating wheel 16, slide 13, and first spring 14, achieving smooth transport of the metal wire.

[0056] Example 2: Please refer to Figure 1 - Figure 16 The difference from embodiment 2 is that the rotating wheel 16 has multiple slots 39 inside, and each slot 39 is slidably connected to a matching arc-shaped seat 40. The surface of the arc-shaped seat 40 has a conveying groove 41 for conveying metal wires. The conveying groove 41 prevents the metal wires from detaching. A second spring 42 is elastically connected between the arc-shaped seat 40 and the slot 39. One end of the second spring 42 is fixedly connected to the arc-shaped seat 40, and the other end is fixedly connected to the inner wall of the slot 39. Through the matching of the insert block 44 and the moving groove 43, the rotating wheel... Wheel 16 can rotate and slide on the surface of rotating rod 15. During the process of conveying stranded metal wire, as the metal wire reel 8 continuously feeds the metal wire, the position of the metal wire winding on the surface of the metal wire reel 8 changes. At this time, the metal wire will move with the conveying groove 41 and the arc-shaped seat 40, causing the wheel 16 to slide on the surface of rotating rod 15, always ensuring that the position of the wheel 16 and the wire feeding position of the metal wire reel 8 correspond, further ensuring the smooth conveying of the metal wire. At the same time, under the action of the arc-shaped seat 40 and the second spring 42, the tension of the metal wire is adjusted during the conveying process, further ensuring the stable conveying of the metal wire.

[0057] The surface of the rotating rod 15 is provided with a moving groove 43, and the inner side of the rotating wheel 16 is fixedly installed with a plug 44 that matches the moving groove 43. The plug 44 can slide inside the moving groove 43. With the plug 44 and the moving groove 43 matching each other, the rotating wheel 16 can rotate and slide on the surface of the rotating rod 15.

[0058] The steps of using this invention are as follows: When the stranding device for cable production is in use, during the process of conveying stranded metal wire, the position of the metal wire wound on the surface of the metal wire reel 8 changes as the metal wire reel 8 continuously feeds the metal wire. At this time, the metal wire will move along with the conveying groove 41 and the arc-shaped seat 40, causing the rotating wheel 16 to slide on the surface of the rotating rod 15, ensuring that the position of the rotating wheel 16 and the wire feeding position of the metal wire reel 8 always correspond, further ensuring the smooth conveying of the metal wire. At the same time, under the action of the arc-shaped seat 40 and the second spring 42, the tension of the metal wire is adjusted during the conveying process, further ensuring the stable conveying of the metal wire.

[0059] A method for stranding wire in cable production, comprising the following steps:

[0060] S1: In the initial state, the rotating frame 4 is stored inside the stacking frame 47. At this time, the metal wire spool 8 is inserted into the insert shaft 7 through the semi-circular groove 49. Then, the limiting block 45 is screwed onto the end of the insert shaft 7. Finally, the locking rod 46 is rotated into the groove on the surface of the insert shaft 7. After the metal wire spool 8 is inserted into the insert shaft 7 in sequence, the motor 35 rotates servo to make the gear ring 32 rotate, thereby making the rotating ring 2 rotate and the rotating disk 3 rotate servo to insert the next set of metal wire spool 8 into the surface of the insert shaft 7.

[0061] S2: After the metal wire spool 8 is completely placed, the electric telescopic rod 37 extends and moves the sliding column 20. The movement of the sliding column 20 causes the toothed plate 22 to slide in the sliding groove 21. The movement of the toothed plate 22 causes the gear 25 to rotate and drive the rotating shaft 24 to rotate, thereby causing multiple rotating frames 4 to rotate out from inside the stacking frame 47. After the rotating frame 4 has rotated, the metal wires on the surface of multiple metal wire spools 8 are pulled out. Each metal wire passes through the surface of the rotating wheel 16 one by one. When the metal wire passes through the surface of the rotating wheel 16, the metal wire will be stuck inside the conveying groove 41. Then the metal wire passes through its corresponding wiring hole 17. The rotation of the rotating frame 4 makes the metal wire spools 8 not on the same horizontal plane. Multiple metal wire spools 8 achieve layering of metal wires on the rotating frame 4. After multiple metal wires pass through their corresponding wiring holes 17, multiple metal wires are put into the inside of the clamping frame 18.

[0062] S3: The motor 35 rotates continuously, causing the gear disc 34 to rotate, which in turn causes the gear ring 32 to rotate, which in turn causes the rotating ring 2 and the rotating disk 3 to rotate. The rotating ring 2 rotates, causing the fixed plate 23 to rotate, which in turn causes the rotating frame 4 to rotate, causing the metal wire reel 8 to rotate. The rotating ring 2 also causes the fixed ring 19 to rotate, which causes the sliding column 20 to rotate, causing the electric telescopic rod 37 to rotate. This causes the rotating disk 36 to rotate inside the first bracket 27. During the cable production process, the rotating ring 2 and the rotating disk 3 rotate synchronously, causing the metal wire reel 8 and the cable routing hole 17 to rotate synchronously. In addition, multiple metal wire reels 8 on the rotating frame 4 achieve layering of metal wires. During the cable production process, the problem of metal wire entanglement is avoided. Finally, the metal wires are twisted through the clamping frame 18.
