It is mainly used to twist multiple conductive cores together according to specific rules and requirements to form a cable with specific structure and performance requirements.

[0003] The Chinese patent application number CN202410118596.9 discloses a stranding device for cable production and a method of use. The device comprises a base, a motor is arranged on the base, the base is rotatably connected to a rotating frame, the rotating frame is rotatably connected to a material placement shaft, the base is rotatably connected to a transfer frame, the transfer frame is fixedly connected to a synchronous shaft, the synchronous shaft is fixedly connected to a synchronous frame, the base is fixedly connected to a clamping frame, the base is rotatably connected to a rotating shell, a first slider is slidably connected in the rotating shell, the first slider is rotatably connected to a leg, and the leg is rotatably connected to a first rotating wheel.

[0004] The present invention pre-deforms the auxiliary wires before twisting them by setting two groups of first rotating wheels and adjusting the relative rotation angle between the two groups of first rotating wheels, so as to prevent the auxiliary wires from being insufficiently deformed when being directly twisted on the main wire, resulting in loose twisting of the auxiliary wires. However, when a traditional twisting mechanism twists the metal conductors, since a plurality of metal wire reels are arranged at the same level on one side of the twisting mechanism, when the metal conductors released by the metal wire reels pass through the row holes, since the plurality of metal wire reels are arranged horizontally, the metal conductors between the row holes and the metal wire reels will swing during the wire releasing process, and the distance between the metal conductors between the row holes and the metal wire reels is relatively close, which will cause adjacent metal conductor wires to become entangled, which will not only affect the production quality of the cable by the twisting mechanism, but also when the metal conductor wires are entangled, the entangled wires need to be untangled, thereby affecting the production efficiency of the cable by the twisting mechanism.

This scheme rotates the multiple rotating frames 4 to pull out the metal wires on the surface of the multiple metal wire reels 8. Each metal wire passes through the surface of the rotating wheel 16 one by one, and then the metal wires pass through the corresponding wire arrangement holes 17. The rotation of the rotating frame 4 makes the various metal wire reels 8 not on the same horizontal plane. The multiple metal wire reels 8 realize the layering of the metal wires on the rotating frame 4. After the multiple metal wires pass through the corresponding wire arrangement holes 17, the multiple metal wires are uniformly placed in the clamping frame 18.Compared with the traditional metal winding reels placed at the same level, the rotating frame 4 rotates so that the various metal wire reels 8 are not on the same horizontal plane. Multiple metal wire reels 8 realize the layering of metal wires on the rotating frame 4. In the process of cable production, the problem of metal wire winding between the wire arrangement hole 17 and the metal wire reel 8 is solved, and the quality of cable production by the stranding device is improved, thereby improving the production efficiency of the cable by the stranding mechanism; in the process of metal wire conveying stranded wire, when the metal wire is suddenly tensioned, the rotating wheel 16 is squeezed and moved, so that the rotating rod 15 moves with the slide 13 to move inside the fixed frame 12 to squeeze the first spring 14. When the metal wire is suddenly relaxed, the slide 13 moves under the action of the first spring 14, and moves with the rotating rod 15 and the rotating wheel 16 to act on the surface of the metal wire. In order to prevent the metal wire from being suddenly tensioned or relaxed, the rotating rod 15, the rotating wheel 16, the slide 13 and the first spring 14 are set to adjust the tension of the metal wire during the conveying process, so as to realize the smooth conveying of the metal wire.

In the process of the metal wire conveying the stranded wire, the metal wire drum 8 continuously feeds the metal wire, and the position of the metal wire wrapped on the surface of the metal wire drum 8 changes. At this time, the metal wire will move with the conveying groove 41 and the arc seat 40, so that the rotating wheel 16 slides on the surface of the rotating rod 15, and the position of the rotating wheel 16 and the wire drum 8 that release the wire are always ensured to correspond, further ensuring the smooth conveying of the metal wire. At the same time, under the action of the arc 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.

[0037] The use steps of the present invention are as follows: when the stranding device for cable production is in use, during the process of the metal wire conveying the stranded wire, the metal wire drum 8 continuously conveys the metal wire, and the position of the metal wire wrapped around the surface of the metal wire drum 8 changes. At this time, the metal wire will move with the conveying groove 41 and the arc seat 40, so that the rotating wheel 16 slides on the surface of the rotating rod 15, and the rotating wheel 16 is always ensured to correspond to the position of the wire unwinding of the metal wire drum 8, further ensuring the smooth conveying of the metal wire.

Finally, the clamping rod 46 is rotated into the groove on the surface of the plug shaft 7.

The sliding column 20 moves and drives the tooth plate 22 to slide in the slide groove 21. The movement of the tooth plate 22 causes the gear 25 to rotate and drives the rotating shaft 24 to rotate, so that the multiple rotating frames 4 are rotated out from the inside of the stacking frame 47. When the rotating frame 4 rotates, the metal wires on the surface of the multiple metal wire drums 8 are pulled out, and 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 in the inside of the conveying groove 41, and then the metal wire will pass through the corresponding wire arrangement holes 17. The rotation of the rotating frame 4 makes the various metal wire drums 8 not on the same horizontal plane. The multiple metal wire drums 8 realize the layering of metal wires on the rotating frame 4. After the multiple metal wires pass through the corresponding wire arrangement holes 17, the multiple metal wires are uniformly placed in the inside of the clamping frame 18. S3: The motor 35 rotates continuously to rotate the gear disc 34, so that the gear ring 32 rotates to rotate the swivel ring 2 and the turntable 3, and the swivel ring 2 rotates to rotate the fixed plate 23, so that the turntable 4 follows the rotation of the swivel ring 2 and rotates the metal wire drum 8, and the rotation of the swivel ring 2 also rotates the fixed ring 19, so that the sliding column 20 rotates to rotate the electric telescopic rod 37, and then the turntable 36 rotates inside the first bracket 27. During the cable production process, the swivel ring 2 and the turntable 3 rotate synchronously, and the metal wire drum 8 and the cable arrangement hole 17 rotate synchronously. In addition, multiple metal wire drums 8 are used to realize the layering of metal wires on the turntable 4. During the cable production process, the problem of metal wire winding is avoided. Finally, the metal wires are twisted through the clamping frame 18.
