Cables have many uses, mainly for control installation, connecting equipment, transmitting power and so on. They are a common and indispensable item in daily life. Because cables are electrified, they need to be installed with special care. In the production process of cables, stranding devices are used to twist many wires into a single cable.

[0003] Some of the stranding devices currently in use lack a mechanism for adjusting cable tension, resulting in unstable cable tension, which affects the quality of stranding and causes problems such as uneven stranding and uneven cable appearance. Utility Model Content

[0004] This utility model proposes a transmission device for a wire and cable stranding machine, which solves the problem that some stranding devices in related technologies lack a mechanism for adjusting cable tension, resulting in unstable cable tension, affecting the quality of stranding, and causing problems such as uneven stranding tightness and uneven cable appearance.

[0005] The technical solution of this utility model is as follows:

[0006] A transmission device for a wire and cable stranding machine, comprising:

[0007] The base has a twisting mechanism at one end of its upper part and a transmission mechanism at the other end of its upper part.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-2 As shown, this embodiment proposes...

[0028] A transmission device for a wire and cable stranding machine includes: a base 1, a stranding mechanism 2 is provided at one end of the upper part of the base 1, and a transmission mechanism 3 is provided at another end of the upper part of the base 1; the stranding mechanism 2 includes a stranding frame 21 and a wire feeding frame 25, the wire feeding frame 25 is movably installed on the surface of the stranding frame 21, and the number of wire feeding frames 25 is several groups and symmetrically distributed on the circumferential surface of the stranding frame 21.

[0029] A main shaft 22 is fixedly connected to the center of the left end of the wire twisting frame 21, and a wire collecting reel 28 is fixedly connected to the center of the right end of the wire twisting frame 21. Wire collecting reel 28 has symmetrically arranged wire-passing holes 29 on its surface. A slide rail 23 is symmetrically arranged on the surface of the wire twisting frame 21. An electric push rod 24 is fixedly connected to the surface of the wire twisting frame 21. The output shaft of the electric push rod 24 is fixedly connected to the wire feeding frame 25. A wire reel 26 is rotatably connected inside the wire feeding frame 25. A wire ring 27 is fixedly connected to the left end of the wire feeding frame 25.

[0030] In this embodiment, by setting a slide rail 23 on the surface of the stranding frame 21, the installation of the wire feeding frame 25 on the upper end of the stranding frame 21 is facilitated. The wire feeding frame 25 is driven to move inside the slide rail 23 by the electric push rod 24, which can adjust the tension of the cable released from the wire reel 26 above the wire feeding frame 25. When the tension sensor of the device detects a fluctuation in the tension of a certain group of cables, the PLC control device of the device controls the corresponding set of electric push rods 24 to adjust the position of the wire feeding frame 25 to adjust the tension of this group of cables. The wire ring 27 facilitates the guidance of the cable to the direction of the wire collecting reel 28. The wire hole 29 opened on the surface of the wire collecting reel 28 facilitates the limiting of all cables and facilitates the final stranding of the cables.

[0031] Example 2

[0032] like Figures 1-4 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0033] The base 1 includes a motor 13 and a limit frame 15. The motor 13 is fixedly mounted on the mounting piece at the upper end of the base 1. The output shaft of the motor 13 is fixedly connected to a lead screw 14. The two ends of the lead screw 14 are rotatably connected to the connecting piece above the base 1.

[0034] Mounting blocks 11 are fixedly connected to both ends of the base 1, and a slide rail 12 is provided in the middle of the surface of the base 1.

[0035] The top center of the limiting frame 15 is rotatably connected to the limiting shaft 16, and the bottom end of the limiting frame 15 is movably connected to the base 1 through the slide rail 12. The lead screw 14 passes through the bottom end of the limiting frame 15 and is threadedly connected to the limiting frame 15.

[0036] The base 1 also includes a mounting bracket 17 fixedly mounted on its surface. An auxiliary pulley 18 is rotatably connected to the upper end of the mounting bracket 17. The wire twisting frame 21 is movably mounted on the upper end of the mounting bracket 17 and its bottom end is rotatably connected to the auxiliary pulley 18.

[0037] The transmission mechanism 3 includes a second motor 31 and a transmission shaft 36. The second motor 31 is fixedly installed at the middle of the left end of the base 1. A first synchronous pulley 32 is fixedly connected to the middle of the output shaft of the second motor 31. The first synchronous pulley 32 is driven by a first synchronous belt 33. The end of the first synchronous belt 33 away from the first synchronous pulley 32 is driven by the main shaft 22.

[0038] The output shaft of motor 2 31 is fixedly connected to the top of synchronous pulley 2 34, and both ends of transmission shaft 36 are rotatably connected to mounting block 11. Both ends of transmission shaft 36 are fixedly connected to synchronous pulley 37.

[0039] The transmission mechanism 3 also includes a synchronous belt 38, a synchronous pulley 34 is connected to a synchronous belt 35, the end of the synchronous belt 35 away from the synchronous pulley 34 is connected to the synchronous pulley 37, one end of the synchronous belt 38 is connected to the limiting shaft 16, and the end of the synchronous belt 38 away from the limiting shaft 16 is connected to the synchronous pulley 37.

[0040] In this embodiment, a limiting frame 15 is used to limit the position of the stranded cable formed by the stranded wires, preventing the cable from shaking during winding and affecting the winding process. When the cable passes through the limiting shaft 16, the limiting shaft 16 restricts the outer diameter of the cable and applies a certain radial pressure to further tighten the individual strands in the cable, improving the cable's tightness and roundness. The motor 13 drives the lead screw 14 to rotate, causing the limiting frame 15 to move left and right within the range of the slide rail 12, ensuring that cables of different specifications are in the optimal limiting position, thereby improving product quality. The motor 2 drives the synchronous belt connected to it. The rotation of synchronous belt 33 and synchronous belt 35 drives the main shaft 22 to rotate synchronously, enabling the stranding frame 21 to rotate and strand the cable. Synchronous belt 35 drives the transmission shaft 36 to rotate synchronously, which in turn drives synchronous belt 38 to rotate. Synchronous belt 38 then drives the limit shaft 16 to rotate. The rotation of the limit shaft 16 reduces friction on the stranded cable as it passes through, preventing damage and extending its service life. By using one motor to drive multiple mechanisms, the transmission structure of the device is optimized, reducing costs.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
