[0019] By synchronously rotating the two stranding plates, driving the wire dividing plate and the wire guiding plate to rotate, a plurality of wire cores and strengthening cores can be stranded at the stranding die.

[0022] The double-headed threaded rod in the wire stabilizing structure can drive the slider to move, and then drive the rod to move, shortening the distance between the two rods, which can play a stabilizing role for smaller diameter wire cores and increasing the application range of the device.

[0023] The cooperative structure inside the fixing frame, by pulling the telescopic support frame to engage the long shaft with the hexagonal block and starting the motor to drive the long shaft to rotate, cooperating with belt two, the coupling, universal joint one and universal joint two, can drive all the cooperative pulleys to rotate synchronously, and then achieve the synchronous rotation of all double-headed threaded rods, achieving the purpose of synchronously adjusting the distance between each pair of rods and improving the adjustment efficiency.

[0024] Through the connection block between the two connecting rings and the connection relationship between the coupling and the connection block, when the stranding plate rotates, it can drive the connecting ring, connection block and coupling to rotate synchronously, and then drive the cooperative structure to rotate stably together with the wire stabilizing structure, ensuring the coordination of the operation between different structures, avoiding the cooperative structure from blocking the operation of the wire stabilizing structure, ensuring that all parts of the entire stranding device can work in coordination. The cooperative structure can rotate stably with the wire stabilizing structure. While ensuring the coordinated operation between structures, it improves the independence of the relative movement of different structures, enabling each structure to function without being overly interfered by other structures, which is beneficial to improving the working efficiency and stability of the entire cable production stranding device and further optimizing the performance of the device.

Main guiding grooves 14 are arranged at the front and rear through the rear parts of the stranding plate 10 and the tooth disc 16.

[0039] A plurality of wire cores 23 to be stranded are sequentially passed through the wire passing grooves 8 and the wire guiding grooves 13 from an external wire pay-off reel. Then, one end of the wire core 23 is passed through the stranding die 5 and then connected to an external traction device. The reinforcing core 24 to be stranded is sequentially passed through the main wire groove 9 and the wire guiding groove 13 from an external wire pay-off reel.

At this time, the two stranding plates 10 are rotated, and through a plurality of connecting frames 45, the wire dividing plate 6 and the lead wire plate 7 are driven to rotate synchronously, so as to strand the plurality of wire cores 23 and the reinforcing core 24 at the position of the stranding die 5;

[0040] During the synchronous rotation of the two stranding plates 10, the two tooth grooves 15 will be driven to rotate synchronously, thereby driving all the stranding gears 11 to revolve synchronously. During the synchronous revolution of all the stranding gears 11, the two tooth discs 16 are driven to rotate together. At the same time, since the stranding gears 11 are meshed with the tooth groove 15 and the tooth disc 16 at the same time, therefore, during the synchronous revolution of all the stranding gears 11, they will also rotate synchronously.

[0044] Start the two motors 25 synchronously, drive the two small belt pulleys 22, and drive the two large belt pulleys 21 to rotate synchronously through the two first belts, so as to drive the four power wheels 20 to rotate synchronously, and then drive the two stranded wire plates 10 to rotate synchronously, and then start the cable stranding work.

[0045] In this embodiment, a plurality of wire cores 23 penetrate through the wire dividing plate 6, the lead plate 7 and the two stranded wire plates 10 through a plurality of wire passing grooves 8, a plurality of wire guiding grooves 13 and a through groove 19. A strengthening core 24 penetrates through the wire dividing plate 6, the lead plate 7 and the two stranded wire plates 10 through a main wire groove 9 and a main guiding groove 14. Connecting rings 46 are rotatably connected to both the front and rear parts inside the fixed frame 3. The two connecting rings 46 are respectively fixedly connected to the two stranded wire plates 10. The through groove 19 is not located at the center position of the stranded wire gear 11.

[0046] In this embodiment, a wire stabilizing structure 26 is arranged between each pair of stranded wire gears 11. The wire stabilizing structure 26 includes two rotating rods 30. A pair of rotating discs 27 are arranged between a pair of stranded wire gears 11. Second rotating rings 29 are fixedly connected to the mutually remote surfaces of the pair of rotating discs 27. The pair of rotating discs 27 are rotatably connected to the pair of stranded wire gears 11 through the two second rotating rings 29. Two connecting bodies 28 are fixedly connected between the pair of rotating discs 27. Chute grooves 31 are formed on the mutually close sides of the two connecting bodies 28. Sliding grooves 32 are formed on the mutually remote sides of the two connecting bodies 28. Two sliders 33 are slidably connected to the inside of each of the two sliding grooves 32. A double-headed threaded rod 34 is rotatably connected to the inside of the sliding groove 32.

[0047] When the wire core 23 passes through the front and rear through grooves 19, it will be located between the two rotating rods 30. Through the two rotatable rotating rods 30, the wire core 23 can be more stable during the process of revolution and rotation, so that the tension distribution of the stranded wire core 23 is consistent, avoiding local over-tightening or loosening, and improving the stability of the electrical performance of the cable.

[0048] Rotate the double-headed threaded rod 34 to drive the two sliders 33 to move closer to each other along the sliding groove 32, thereby driving the two rotating rods 30 to move closer to each other along the sliding groove 31, thereby shortening the distance between the two rotating rods 30, so as to stably act on the wire core 23 with a smaller diameter.

[0049] In this embodiment, the two threads of the double-headed threaded rod 34 are opposite, and the double-headed threaded rod 34 is threadedly connected to the two sliders 33.

[0050] In this embodiment, the rotating rod 30 is rotatably connected to the slider 33. The rotating rod 30 penetrates through the sliding groove 31, and the sliding groove 31 is communicated with the sliding groove 32.

[0051] In this embodiment, a cooperation structure 35 is arranged inside the fixing frame 3. The cooperation structure 35 includes a plurality of universal joints one 38 and a plurality of universal joints two 41. The top of each double-headed threaded rod 34 penetrates through the top of a plurality of connectors 28 and is fixedly connected with a cooperation belt pulley 36. A belt two 37 is sleeved between adjacent two cooperation belt pulleys 36. A telescopic support frame 43 is slidably connected to the side of the fixing frame 3. A motor 44 is fixedly connected to the side of the telescopic support frame 43. The output shaft of the motor 44 penetrates through the inside of the fixing frame 3 and is fixedly connected with a long shaft 42. A hexagonal block 47 is fixedly connected to the side of one of the cooperation belt pulleys 36. One end of the long shaft 42 is adaptively matched with the hexagonal block 47. A universal joint one 38 is fixedly connected to the top. A plurality of universal joints one 38 are respectively fixedly connected to all the cooperation belt pulleys 36 except one of the cooperation belt pulleys 36 and another cooperation belt pulley 36 adjacent to it. One end of each universal joint one 38 is fixedly connected with a connecting shaft 40. A plurality of universal joints two 41 are fixedly connected between adjacent two connecting shafts 40.

[0052] When it is necessary to synchronously adjust the distance between each pair of rotating rods 30, pull the telescopic support frame 43 to drive the long shaft 42 to move, and then make one end of the long shaft 42 engage with the hexagonal block 47. At this time, start the motor 44 to drive the long shaft 42 to rotate, and then drive one of the cooperation belt pulleys 36 to rotate together through the hexagonal block 47, and then drive the adjacent cooperation belt pulleys 36 to rotate synchronously with the cooperation of the belt two 37, and further drive all the connecting shafts 40 through all of them. The universal joint one 38 and the universal joint two 41 can drive all the cooperation belt pulleys 36 to rotate synchronously, so as to drive all the double-headed threaded rods 34 to rotate synchronously, so as to achieve the purpose of synchronously adjusting the distance between each pair of rotating rods 30.

[0053] In this embodiment, a number of connecting blocks 39 are fixedly connected between the two connecting rings 46. The connecting shaft 40 is rotatably connected to the connecting blocks 39. During the rotation of the two stranding plates 10, the two connecting rings 46 will be driven to rotate synchronously, and then a number of connecting blocks 39 will be driven to rotate synchronously. Therefore, a number of connecting blocks 39 can drive a number of connecting shafts 40 to revolve synchronously. Therefore, the cooperative structure 35 can be driven to rotate stably together with a number of wire stabilizing structures 26, avoiding the cooperative structure 35 from blocking the operation of the wire stabilizing structure 26, thereby improving the operation coordination between different structures and the independence of relative movement.

[0054] It should be noted that the present invention is a cable production stranding device. When in use, a number of wire cores 23 to be stranded are sequentially passed through the wire passing grooves 8 and the wire guiding grooves 13 from an external wire pay-off reel, and then one end of the wire core 23 is passed through the stranding die 5 and then connected to an external traction device. The reinforcing core 24 to be stranded is sequentially passed through the main wire groove 9 and the wire guiding groove 13 from an external wire pay-off reel, and then one end of the reinforcing core 24 is passed through the stranding die 5 and then connected to an external traction device. At this time, the two stranding plates 10 are rotated, and through a number of connecting frames 45, the wire dividing plate 6 and the wire guiding plate 7 are driven to rotate synchronously, and then a number of wire cores 23 and the reinforcing core 24 are stranded at the position of the stranding die 5;

[0055] During the synchronous rotation of the two stranding plates 10, the two tooth grooves 15 will be driven to rotate synchronously, and then all the stranding gears 11 will be driven to revolve synchronously. During the synchronous revolution of all the stranding gears 11, the two tooth discs 16 will be driven to rotate together. At the same time, since the stranding gears 11 are meshed with the tooth grooves 15 and the tooth discs 16 at the same time, therefore, during the synchronous revolution of all the stranding gears 11, they will also rotate synchronously. Therefore, when the through groove 19 is driven to revolve, it will also rotate. Since the wire core 23 also passes through the through groove 19, therefore, through the through groove 19, the wire core 23 can be driven to rotate during the revolution stranding process and also rotate during the self-rotation stranding process. The two motors 25 are started synchronously, driving the two small belt pulleys 22, and through the two belts 1, the two large belt pulleys 21 are driven to rotate synchronously, so as to drive the four driving wheels 20 to rotate synchronously, and then drive the two stranding plates 10 to rotate synchronously, and then start the cable stranding work;

[0056] When the wire core 23 passes through the front and rear through grooves 19, it will be located between the two rotating rods 30. Through the two rotatable rotating rods 30, the wire core 23 can be made more stable during the revolution and self-rotation processes, so that the tension distribution of the stranded wire core 23 is consistent, avoiding local over-tightening or loosening, and improving the stability of the electrical performance of the cable;

[0057] Rotate the double-headed threaded rod 34 to drive the two sliders 33 to move closer to each other along the sliding groove 32, thereby driving the two rotating rods 30 to move closer to each other along the sliding groove 31, so as to shorten the distance between the two rotating rods 30, and thus can stably act on the wire core 23 with a smaller diameter. When it is necessary to synchronously adjust the distance between each pair of rotating rods 30, pull the telescopic support frame 43 to drive the long shaft 42 to move, and then make one end of the long shaft 42 engage with the hexagonal block 47. At this time, start the motor 44 to drive the long shaft 42 to rotate, and then drive one of the cooperative pulleys 36 to rotate together through the hexagonal block 47, and then cooperate with the second belt 37 to drive the adjacent cooperative pulley 36 to rotate synchronously. Furthermore, through all the coupling shafts 40, the first universal joint 38 and the second universal joint 41, all the cooperative pulleys 36 can be driven to rotate synchronously, so as to drive all the double-headed threaded rods 34 to rotate synchronously, and thus achieve the purpose of synchronously adjusting the distance between each pair of rotating rods 30.
