It is mainly used to transmit electrical energy, transmit signals, or achieve electrical connections. It is an indispensable infrastructure in modern power systems, communication networks, and electronic equipment.

[0003] Chinese patent CN117623002B discloses a cable stranding device, comprising: a support frame, a stranding disc, a wire roller, a unloading assembly, and a loading assembly. The stranding disc is rotatably connected to the support frame. A first driving member is provided inside the stranding disc to drive the stranding disc to rotate. The stranding disc is provided with a plurality of first positioning rods spaced apart along its circumference. A positioning plate is provided at the center of the stranding disc.

[0004] In the aforementioned patents and prior art, the multiple strands of wire need to be rotated during the twisting process. In the long-term production process, the rotation of the multiple strands of wire may cause the wire to break. If the wire breaks, other equipment will continue the twisting operation, which will result in unqualified products and a large amount of material waste. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wire stranding device and a method for producing multi-strand cables.

[0009] Preferably, the wire stranding mechanism includes a turntable mounting base, which is mounted on the top of the workbench body. A middle turntable for the wire is rotatably mounted inside the turntable mounting base. Multiple middle turntable rollers are installed inside the middle turntable. A turntable connecting cylinder is installed inside the middle turntable. A front turntable for the wire is mounted outside the turntable connecting cylinder.

The two sides of the middle turntable of the conductor are connected to the front turntable and the rear turntable of the conductor respectively through turntable connecting cylinders.

[0011] The stranding drive mechanism can drive the middle turntable of the conductor to rotate inside the turntable mounting base. When the middle turntable of the conductor rotates, it can drive the front turntable and the rear turntable of the conductor to rotate through the turntable connecting cylinder. When the middle turntable, the front turntable and the rear turntable of the conductor rotate, they can drive multiple conductors to rotate synchronously. When the rear turntable of the conductor rotates, it can also drive the conductor mounting mechanism to rotate.

[0012] Preferably, the wires on the wire mounting mechanism pass sequentially through the rear turntable, the middle turntable, and the front turntable, and the rear turntable, the middle turntable, and the front turntable guide the movement direction of the wires through the central wire channel, the middle turntable roller, and the front turntable roller, respectively.

[0013] The center guide channel of the turntable connecting cylinder is on the same straight line as the center of the guide merging mechanism and the guide moving mechanism.

[0014] Preferably, the wire mounting mechanism includes multiple sliding mounting brackets and multiple fixed limiting brackets. The sliding mounting brackets are all slidably mounted inside the rear turntable of the wire, and the fixed limiting brackets are all mounted outside the fixed limiting brackets. A wire mounting turntable is rotatably mounted inside each sliding mounting bracket. A mounting bracket spring is installed inside each sliding mounting bracket. A transmission block is connected to the outside of each sliding mounting bracket. A transmission connecting ring is installed outside the transmission block. A transmission connecting plate is installed outside the transmission connecting ring.

[0015] Preferably, a plurality of the sliding mounting brackets are arranged in a ring inside the rear turntable of the conductor. The conductor mounting turntable is slidably mounted on the outside of the rear turntable of the conductor via the sliding mounting brackets. The inside of the sliding mounting brackets is connected to the outside of the rear turntable of the conductor via mounting bracket springs. The outside of the conductor mounting turntable has a polygonal structure.

[0016] When the sliding mounting bracket moves inside the rear turntable of the wire, it can drive the wire mounting turntable to move inside the fixed limiting bracket. When the mounting bracket spring drives the wire mounting turntable to move towards the fixed limiting bracket, it can drive the wire mounting turntable to contact the inside of the fixed limiting bracket. When the wire mounting turntable contacts the inside of the fixed limiting bracket, the fixed limiting bracket can engage with the outside of the wire mounting turntable.

[0017] Preferably, the outer surfaces of the plurality of transmission blocks are in contact with the outer surface of the transmission connecting ring, the bottom of the transmission connecting plate passes through the top of the workbench body and is connected to the twisting drive mechanism, the transmission connecting ring is slidably mounted on the top of the workbench body through the transmission connecting plate, and the outer surface of the transmission blocks is engaged with the outer surface of the transmission connecting ring.

[0018] When the sliding mounting bracket moves, it can drive the transmission block to move synchronously. When the transmission block moves, it can drive the transmission connecting plate to move inside the main body of the workbench.

[0022] The stranded motor drives the motor wheel to rotate, which in turn drives the movable wheel to rotate via the transmission belt. When the movable wheel rotates, it drives the wheel mounting rod to rotate. When the wheel mounting rod rotates, it drives the transmission roller to rotate. When the transmission roller rotates, it drives the turntable in the middle of the wire to rotate. After the transmission connecting plate drives the movable wheel to move, the movable wheel rotates and no longer drives the wheel mounting rod to rotate.

[0023] A method for producing multi-strand cables uses the aforementioned conductor stranding device.

[0024] Compared with the prior art, the present invention provides a wire stranding device and a method for producing multi-strand cables, which has the following advantages:

[0025] 1. In this type of wire stranding device, when the movable wheel is in the thicker part outside the wheel mounting rod, the rotation of the movable wheel can drive the wheel mounting rod to rotate synchronously. When the movable wheel is in the thinner part outside the wheel mounting rod, the rotation of the movable wheel no longer drives the wheel mounting rod to rotate. At this time, the rotation of the movable wheel no longer drives the transmission roller to rotate, thereby stopping the stranding drive mechanism from driving the wire stranding mechanism to rotate, thus stopping the wire stranding operation. This can prevent the production of unqualified products and also prevent the waste of other materials caused by the breakage of a single wire.

[0026] 2. This type of conductor stranding device can drive the front and rear conductor turntables connected to both ends of the turntable connecting cylinder to rotate synchronously when the middle turntable rotates. When the middle, front, and rear conductor turntables rotate, they can drive the multiple conductors to rotate synchronously outside the central conductor. When the multiple conductors rotate, they can cover the outside of the central conductor. By driving the synchronous rotation of the middle, front, and rear conductor turntables, the multiple conductors can be evenly distributed outside the central conductor, thereby ensuring the production quality of the multi-strand cable.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a wire stranding device and a method for producing multi-strand cables. Example

[0038] Please see Figure 1 - Figure 8A wire stranding device includes a workbench body 1, a wire stranding mechanism 2 installed on the top of the workbench body 1, a wire installation mechanism 3 installed outside the wire stranding mechanism 2, a stranding drive mechanism 4 installed inside the workbench body 1, a wire merging mechanism 5 installed on the top of the workbench body 1, and a wire moving mechanism 6 installed on the top of the workbench body 1.

[0039] The top of the stranding drive mechanism 4 passes through the workbench body 1 and is connected to the wire stranding mechanism 2 for transmission, and the bottom of the wire mounting mechanism 3 passes through the stranding drive mechanism 4 and is connected to the stranding drive mechanism 4.

[0040] The conductor stranding mechanism 2 can pull and gather the conductors on the conductor mounting mechanism 3. The stranding drive mechanism 4 can drive the conductor stranding mechanism 2 to rotate. When the conductor stranding mechanism 2 rotates, it can drive the conductor to rotate and strand the conductor. The conductor mounting mechanism 3 can control the wire release speed. The conductor mounting mechanism 3 can control the transmission connection inside the stranding drive mechanism 4. The conductor merging mechanism 5 and the conductor moving mechanism 6 can guide and move the conductor after stranding.

[0041] During wire stranding, the center wire of the multi-strand cable passes sequentially through the center of the wire stranding mechanism 2, the wire merging mechanism 5, and the wire moving mechanism 6, and connects to other external equipment. The other wires are mounted on the wire mounting mechanism 3. During cable stranding, the stranding drive mechanism 4 drives the wire stranding mechanism 2 and the wire mounting mechanism 3 to rotate. During rotation, the wires on the wire mounting mechanism 3 are guided and rotated by the wire stranding mechanism 2 to be stranded around the center wire. Throughout the stranding process, the multi-strand wires remain taut. During the multi-strand cable production process, one of the wires... When a wire breaks, the wire installation mechanism 3 can move outside the wire stranding mechanism 2. When the wire installation mechanism 3 moves outside the wire stranding mechanism 2, it can change the transmission connection relationship inside the stranding drive mechanism 4. After the connection relationship inside the stranding drive mechanism 4 is changed, the stranding drive mechanism 4 no longer drives the wire stranding mechanism 2 to rotate. After the wire stranding mechanism 2 stops rotating, the wire stranding production also stops. When the wire breaks, the production of the wire also stops immediately, which can effectively prevent one strand of wire from continuing to produce unqualified cables after the breakage, thereby preventing the waste of production materials during the production process. Example

[0042] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 8The wire stranding mechanism 2 includes a turntable mounting base 21, which is mounted on the top of the workbench body 1. A middle turntable 22 for the wire is rotatably mounted inside the turntable mounting base 21. Multiple middle turntable rollers 23 are installed inside the middle turntable 22. A turntable connecting cylinder 24 is installed inside the middle turntable 22. A front turntable 25 for the wire is mounted outside the turntable connecting cylinder 24. A front turntable roller 26 is installed inside the front turntable 25. A rear turntable 27 for the wire is mounted outside the turntable connecting cylinder 24. A rear turntable roller 28 is installed inside the rear turntable 27. A central wire channel 29 is opened inside the turntable connecting cylinder 24.

[0043] The outside of the middle turntable 22 of the conductor is connected to the stranding drive mechanism 4. The inside of the middle turntable 22 of the conductor is provided with multiple openings for the conductor to pass through. The middle turntable roller 23 is installed in the openings inside the middle turntable 22 of the conductor. The two sides of the middle turntable 22 of the conductor are connected to the front turntable 25 and the rear turntable 27 of the conductor respectively through the turntable connecting cylinder 24.

[0044] The stranding drive mechanism 4 can drive the middle turntable 22 of the conductor to rotate inside the turntable mounting base 21. When the middle turntable 22 of the conductor rotates, it can drive the front turntable 25 and the rear turntable 27 of the conductor to rotate through the turntable connecting cylinder 24. When the middle turntable 22, the front turntable 25 and the rear turntable 27 of the conductor rotate, they can drive multiple conductors to rotate synchronously. When the rear turntable 27 of the conductor rotates, it can also drive the conductor mounting mechanism 3 to rotate.

[0045] The wires on the wire installation mechanism 3 pass through the rear turntable 27, the middle turntable 22, and the front turntable 25 in sequence. The rear turntable 27, the middle turntable 22, and the front turntable 25 guide the movement direction of the wires through the central wire channel 29, the middle turntable roller 23, and the front turntable roller 26, respectively.

[0046] The center wire channel 29 of the turntable connecting cylinder 24 is on the same straight line as the center of the wire merging mechanism 5 and the wire moving mechanism 6.

[0047] During the stranding of multi-strand cables, the center wire passes through the center wire channel 29 in the center of the turntable connecting cylinder 24, and then sequentially passes through the wire merging mechanism 5 and the wire moving mechanism 6. Meanwhile, the multi-strand wires inside the wire mounting mechanism 3 on the rear turntable 27 pass through the rear turntable 27, the middle turntable 22, and the front turntable 25 respectively. As the multi-strand wires pass through these turntables, the movement direction is guided by the center wire channel 29, the middle turntable roller 23, and the front turntable roller 26. The stranding process is driven by... Mechanism 4 can drive the middle turntable 22 of the conductor to rotate. When the middle turntable 22 of the conductor rotates, it can drive the front turntable 25 and the rear turntable 27 of the conductor connected to both ends of the turntable connecting cylinder 24 to rotate synchronously. When the middle turntable 22, the front turntable 25 and the rear turntable 27 of the conductor rotate, they can drive the multi-strand conductors to rotate synchronously outside the central conductor. When the multi-strand conductors rotate, they can cover the outside of the central conductor. By driving the multi-strand conductors to rotate synchronously through the rotation of the middle turntable 22, the front turntable 25 and the rear turntable 27 of the conductor, the multi-strand conductors can be evenly distributed outside the central conductor, thereby ensuring the production quality of the multi-strand cable. Example

[0048] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 8 The wire mounting mechanism 3 includes multiple sliding mounting brackets 31 and multiple fixed limiting brackets 33. The sliding mounting brackets 31 are slidably mounted inside the rear turntable 27 of the wire, and the fixed limiting brackets 33 are mounted outside the fixed limiting brackets 33. The wire mounting turntable 32 is rotatably mounted inside the sliding mounting bracket 31. The mounting bracket spring 34 is installed inside the sliding mounting bracket 31. The transmission block 35 is connected to the outside of the sliding mounting bracket 31. The transmission connecting ring 36 is installed outside the transmission block 35. The transmission connecting plate 37 is installed outside the transmission connecting ring 36.

[0049] Multiple sliding mounting brackets 31 are arranged in a ring inside the rear turntable 27 of the conductor. The conductor mounting turntable 32 is slidably mounted on the outside of the rear turntable 27 of the conductor via the sliding mounting brackets 31. The inside of the sliding mounting brackets 31 is connected to the outside of the rear turntable 27 of the conductor via mounting bracket springs 34. The outside of the conductor mounting turntable 32 has a polygonal structure.

[0050] When the sliding mounting bracket 31 moves inside the rear turntable 27 of the wire, it can drive the wire mounting turntable 32 to move inside the fixed limiting bracket 33. When the mounting bracket spring 34 drives the wire mounting turntable 32 to move towards the fixed limiting bracket 33, it can drive the wire mounting turntable 32 to contact the inside of the fixed limiting bracket 33. When the wire mounting turntable 32 contacts the inside of the fixed limiting bracket 33, the fixed limiting bracket 33 can engage with the outside of the wire mounting turntable 32.

[0051] The exterior of multiple transmission blocks 35 is in contact with the exterior of the transmission connecting ring 36. The bottom of the transmission connecting plate 37 passes through the top of the workbench body 1 and is connected to the twisting drive mechanism 4. The transmission connecting ring 36 is slidably mounted on the top of the workbench body 1 through the transmission connecting plate 37. The exterior of the transmission blocks 35 is engaged with the exterior of the transmission connecting ring 36.

[0052] When the sliding mounting bracket 31 moves, it can drive the transmission block 35 to move synchronously. When the transmission block 35 moves, it can drive the transmission connecting plate 37 to move inside the workbench body 1. When the transmission connecting plate 37 moves, it can adjust the connection relationship inside the twisting drive mechanism 4.

[0053] The twisting drive mechanism 4 includes a twisting motor 41 and a rotating wheel mounting rod 44. The twisting motor 41 is installed inside the workbench body 1, and the rotating wheel mounting rod 44 is installed on the top inside the workbench body 1. A motor rotating wheel 42 is installed on the drive end of the twisting motor 41. A transmission belt 43 is installed on the outside of the motor rotating wheel 42. A movable rotating wheel 45 is installed on the outside of the rotating wheel mounting rod 44, and a transmission roller 46 is installed on the outside of the rotating wheel mounting rod 44.

[0054] The outer part of the transmission roller 46 passes through the top of the workbench body 1 and is connected to the outer part of the turntable 22 in the middle of the guide wire.

[0055] The motor wheel 42 is externally connected to the movable wheel 45 via a transmission belt 43. The movable wheel 45 is externally rotatably connected to the transmission connecting plate 37. The diameter of the wheel mounting rod 44 is different.

[0056] The stranding motor 41 drives the motor wheel 42 to rotate, which in turn drives the movable wheel 45 to rotate via the transmission belt 43. When the movable wheel 45 rotates, it drives the wheel mounting rod 44 to rotate. When the wheel mounting rod 44 rotates, it drives the transmission roller 46 to rotate. When the transmission roller 46 rotates, it drives the turntable 22 in the middle of the wire to rotate. After the transmission connecting plate 37 drives the movable wheel 45 to move, the movable wheel 45 rotates and no longer drives the wheel mounting rod 44 to rotate.

[0057] When the stranding motor 41 drives the motor wheel 42 to rotate, it can drive the movable wheel 45 to rotate via the external transmission belt 43. When the movable wheel 45 rotates, it can drive the wheel mounting rod 44 to rotate. When the wheel mounting rod 44 rotates, it can drive the transmission roller 46 to rotate. When the transmission roller 46 rotates, it can drive the conductor middle turntable 22 to rotate inside the turntable mounting base 21, thereby driving the conductor front turntable 25 and conductor rear turntable 27 to rotate synchronously, so as to drive multiple conductors to be stranded on the outside of the central conductor. When the external equipment drives the central conductor to move inside the conductor merging mechanism 5 and the conductor moving mechanism 6, it can be driven to coil around the conductor mounting turntable by traction. The external wires of the 32 gradually disperse. During the traction process, the mounting frame spring 34 remains relaxed. If one of the strands of wire breaks during the twisting of multiple strands, the wire mounting turntable 32 connected to that strand loses the traction of the wire. The mounting frame spring 34 contracts, causing the sliding mounting frame 31 to move towards the fixed limiting frame 33. As the sliding mounting frame 31 moves towards the fixed limiting frame 33, it can simultaneously drive the wire mounting turntable 32 to move towards the fixed limiting frame 33. When the wire mounting turntable 32 moves towards the fixed limiting frame 33, the polygonal structure on the outside of the wire mounting turntable 32 can interact with the interior of the fixed limiting frame 33. When the wire mounting turntable 32 is engaged with the fixed limiting frame 33, the wire mounting turntable 32 cannot continue to rotate to loosen the wire. When the sliding mounting frame 31 moves towards the fixed limiting frame 33, it can also drive the transmission block 35 connected to it to move towards the fixed limiting frame 33. When the transmission block 35 moves towards the fixed limiting frame 33, it can drive the transmission connecting ring 36 to move synchronously. When the transmission connecting ring 36 moves towards the fixed limiting frame 33, it can drive the transmission connecting plate 37 to move towards the fixed limiting frame 33 inside the workbench body 1. And when the transmission connecting plate 37 moves, it can drive the movable rotating wheel 45 from the rotating... When the thicker part of the wheel mounting rod 44 moves, the thinner part of the wheel mounting rod 44 rotates. When the movable wheel 45 is on the thicker part of the wheel mounting rod 44, the rotation of the movable wheel 45 can drive the wheel mounting rod 44 to rotate synchronously. When the movable wheel 45 is on the thinner part of the wheel mounting rod 44, the rotation of the movable wheel 45 no longer drives the wheel mounting rod 44 to rotate. At this time, the rotation of the movable wheel 45 no longer drives the transmission roller 46 to rotate, thereby stopping the stranding drive mechanism 4 from driving the wire stranding mechanism 2 to rotate, thus stopping the wire stranding operation. This can prevent the production of unqualified products and also prevent the waste of other materials caused by the breakage of a single wire. Example

[0058] A method for producing multi-strand cables, using a conductor stranding device as described in Examples 1 to 3, includes the following steps:

[0059] First, the center wire is passed through the center of the wire stranding mechanism 2, the wire merging mechanism 5, and the wire moving mechanism 6 in sequence;

[0060] Then, the stranding drive mechanism 4 drives the wire stranding mechanism 2 and the wire mounting mechanism 3 to rotate, stranding the multiple wires around the outside of the central wire.

[0061] When one of the wires breaks, the wire mounting mechanism 3 can move outside the wire stranding mechanism 2;

[0062] When the wire installation mechanism 3 moves outside the wire stranding mechanism 2, it can cause the through relationship inside the stranding drive mechanism 4 to change.

[0063] After the transmission relationship inside the stranding drive mechanism 4 changes, the stranding drive mechanism 4 no longer drives the wire stranding mechanism 2 to rotate.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The bottom of the transmission connecting plate passes through the top of the workbench body and is connected to the twisting drive mechanism. The transmission connecting ring is slidably mounted on the top of the workbench body through the transmission connecting plate. The exterior of the transmission blocks engages with the exterior of the transmission connecting ring. When the sliding mounting bracket moves, it can drive the transmission block to move synchronously. When the transmission block moves, it can drive the transmission connecting plate to move inside the main body of the workbench. When the transmission connecting plate moves, it can adjust the connection relationship inside the twisting drive mechanism.

6. A wire stranding device according to claim 5, characterized in that: The twisting drive mechanism includes a twisting motor and a rotating wheel mounting rod. The twisting motor is installed inside the main body of the workbench, and the rotating wheel mounting rod is installed at the top inside the main body of the workbench. A motor rotating wheel is installed at the drive end of the twisting motor, a transmission belt is installed on the outside of the motor rotating wheel, a movable rotating wheel is installed on the outside of the rotating wheel mounting rod, and a transmission roller is installed on the outside of the rotating wheel mounting rod. The external transmission roller passes through the top of the workbench body and is connected to the external transmission of the turntable in the middle of the guide wire.

7. A wire stranding device according to claim 6, characterized in that: The motor wheel is externally connected to the movable wheel via a transmission belt. The movable wheel is externally rotatably connected to the transmission connecting plate. The diameters of the wheel mounting rods are different. The stranded motor drives the motor wheel to rotate, which in turn drives the movable wheel to rotate via the transmission belt. When the movable wheel rotates, it drives the wheel mounting rod to rotate. When the wheel mounting rod rotates, it drives the transmission roller to rotate. When the transmission roller rotates, it drives the turntable in the middle of the wire to rotate. After the transmission connecting plate drives the movable wheel to move, the movable wheel rotates and no longer drives the wheel mounting rod to rotate.
