[0002] Cables generally consist of three parts: conductor, insulation layer, and protective layer. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits. During the production process, multiple sets of metal wires are twisted together using a stranding machine to form a cable.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] This utility model provides, for example Figures 1 to 7 The cable stranding machine shown includes a housing 1, a mounting frame 2, and a guide frame 5. The mounting frame 2 is installed inside the housing 1, and the guide frame 5 is installed outside the mounting frame 2. Connecting discs 51 are fixedly connected to both ends of the guide frame 5. A first guide shaft 52 and a second guide shaft 53 are fixedly connected to the center of the two sets of connecting discs 51, respectively. The first guide shaft 52 is rotatably connected to the left wall of the housing 1 and the left end of the mounting frame 2, and the second guide shaft 53 is rotatably connected to the right wall of the housing 1 and the right end of the mounting frame 2. A drive motor 12 is fixedly installed on the left side of the housing 1. The output end of the drive motor 12 is fixedly connected to the left end of the first guide shaft 52. The right ends of the first guide shaft 52 and the second guide shaft 53 are both provided with wire holes 55. The left end of the wire holes 55 is provided with wire grooves 56. The inside of the wire grooves 56 is rotatably connected to two sets of second guide wheels 57. The inner surface of the guide frame 5 is rotatably connected to multiple sets of first guide wheels 54. The surface of the second guide shaft 53 is fixedly connected to the drive gear 58. The inner side of the mounting frame 2 is equipped with a winding reel 6. The left inner wall of the mounting frame 2 is equipped with a traction assembly 3. The rear side of the mounting frame 2 is provided with a pulley group 4.

[0038] During equipment installation, the equipment housing 1 is installed on the left side of the stranding reel. The stranding reel is used to twist multiple sets of metal wires to form a cable. Then, the twisted cable is passed through the wire hole 55 and wire groove 56 inside the second guide shaft 53 and inserted into the interior of the equipment housing 1. Next, the cable is placed against the inner wall of the guide frame 5 and secured to the inner side of multiple sets of first guide wheels 54. Then, the cable is passed through the wire groove 56 and wire hole 55 inside the first guide shaft 52 and introduced into the interior of the mounting frame 2. Then, the cable is pulled by the traction component 3 and guided by the pulley group 4. Finally, it is fixed on the surface of the take-up reel 6.

[0039] During the winding process, the output end of the drive motor 12 drives the first guide shaft 52 to rotate, and the first guide shaft 52 drives the guide frame 5 and the second guide shaft 53 to rotate. The rotation direction of the first guide shaft 52, the second guide shaft 53 and the guide frame 5 is opposite to the rotation direction of the stranding disc. The two sets of forces in different directions work together to further tighten the cable, making the metal wires fit together tightly, effectively improving the stranding quality of the cable. When the cable moves, the two sets of second guide wheels 57 on the left and right support the cable and rotate with the movement of the cable to reduce wear on the cable.

[0040] Example 2:

[0041] See Figure 2 , Figure 6 , Figure 7 and Figure 9 Two sets of connecting rods 21 are fixedly connected between the inner walls of the left and right sides of the mounting frame 2. A counterweight 22 is fixedly connected to the inner wall of the left side of the mounting frame 2. A second magnet 28 is fixedly connected to the lower end of the counterweight 22. A first magnet 13 is fixedly connected to the bottom wall of the equipment box 1 at the position below the second magnet 28. A first transmission gear set 26 and a second transmission gear set 27 are respectively provided at the left and right ends of the mounting frame 2. A transmission rod 23 is rotatably connected to the right surface of the counterweight 22. The left end of the transmission rod 23 is connected to the first transmission gear set 26. A support rod is fixedly connected to the inner wall of the right side of the mounting frame 2 at the position opposite to the transmission rod 23. A transmission shaft 25 is rotatably connected to the upper position between the inner walls of the left and right sides of the mounting frame 2. The two ends of the transmission shaft 25 are respectively connected to the first transmission gear set 26 and the second transmission gear set 27 on both sides.

[0042] Simultaneously, during the rotation of the second guide shaft 53, the second guide shaft 53 drives the drive gear 58 to rotate, which in turn drives multiple gears inside the second transmission gear set 27 to rotate. Simultaneously, the second transmission gear set 27 drives multiple gears inside the first transmission gear set 26 to rotate via the transmission shaft 25. During the installation of the take-up reel 6, it is first placed at an angle, with its right end fitted onto the surface of the support rod. Then, it is slid to the right, making the sliding shaft of the take-up reel 6 horizontal. Next, the take-up reel 6 is slid to the left, with its left end fitted onto the surface of the transmission rod 23. After sliding to the leftmost end, the locking sleeve on the surface of the support rod limits the right end of the take-up reel 6, preventing it from sliding to the right. At this time, as the first transmission gear set 26 rotates, it drives the transmission rod 23 to rotate, which in turn drives the take-up reel 6 to rotate, winding up the cable.

[0043] Furthermore, during use, the first magnet 13 and the second magnet 28 work together to effectively improve the stability of the mounting bracket 2 during use and prevent the mounting bracket 2 from shaking.

[0044] See Figure 6 and Figure 7 The upper side of the counterweight 22 is rotatably connected to the first guide wheel 24. The traction assembly 3 includes a first traction wheel 31 and a second traction wheel 32. Both the first traction wheel 31 and the second traction wheel 32 are rotatably connected to the left wall of the mounting frame 2. A transmission belt 33 is connected between the first traction wheel 31 and the second traction wheel 32. The left end of the first traction wheel 31 is connected to the first transmission gear set 26.

[0045] When the cable is inserted into the inner side of the mounting bracket 2, it first goes around the right side of the first guide wheel 24, then winds upward from the bottom side of the second traction wheel 32, and then winds downward from the top side of the first traction wheel 31, winding multiple times between the first traction wheel 31 and the second traction wheel 32.

[0046] During the traction process, the first transmission gear set 26 drives the first traction wheel 31 to rotate. The first traction wheel 31 drives the second traction wheel 32 to rotate synchronously via the transmission belt 33, thus tractioning the cable. During the movement between the first traction wheel 31 and the second traction wheel 32, the first traction wheel 31 and the second traction wheel 32 repeatedly compress the cable, tightening it and further improving the tightness of the internal metal wire connections. (See reference) Figures 6 to 8The pulley block 4 includes a fixed block 41, a first pulley 411, a second pulley 412, a tension rod 413, a tension wheel 414, a reciprocating screw 42, a slider 421, a third pulley 422, a limiting rod 43, a limiting block 431, a fourth pulley 432, and a guide ring 433. The fixed block 41 is fixedly connected to the left inner wall of the mounting frame 2. The left and right ends of the reciprocating screw 42 are rotatably connected to the right end of the fixed block 41 and the right inner wall of the mounting frame 2, respectively. The right end of the reciprocating screw 42 passes through the right wall of the mounting frame 2 and is connected to the second transmission gear set 27. The two ends of the limiting rod 43 are fixedly connected to the left and right inner walls of the mounting frame 2, respectively. The pulley 411 is rotatably connected to the front surface of the fixed block 41, the second pulley 412 is rotatably connected to the upper surface of the fixed block 41, the rear end of the tensioning rod 413 is rotatably connected to the right end of the fixed block 41, the tensioning wheel 414 is rotatably connected to the front end of the tensioning rod 413, the slider 421 is threadedly connected to the reciprocating lead screw 42, the third pulley 422 is rotatably connected to the upper surface of the slider 421, the limiting block 431 is slidably connected to the limiting rod 43, the rear end of the limiting block 431 is fixedly connected to the slider 421, the fourth pulley 432 is rotatably connected to the upper surface of the limiting block 431, and the guide ring 433 is fixedly connected to the front surface of the limiting block 431.

[0047] In addition, after the cable is pulled out from the traction assembly 3, it is pulled backward and overlapped on the upper side of the first pulley 411. Then it passes through the rear side of the second pulley 412, then through the front side of the tensioning wheel 414, then around the rear side of the third pulley 422, then around the upper side of the fourth pulley 432. After passing the cable through the inside of the wire loop 433, the cable is fixed on the surface of the take-up reel 6. During the winding process, the tensioning rod 413 is in the front-back direction, the tensioning wheel 414 is at the front end, and the slider 421 is at the left end.

[0048] During the cable winding process, the second transmission gear set 27 drives the reciprocating screw 42 to rotate. The reciprocating screw 42 drives the slider 421 to slide to the right on its surface, laying the cable flat on the surface of the winding reel 6. When the cable is laid to the far right, the slider 421 just slides to the far right end. At this time, the slider 421 will slide to the left, and then drive the cable to be laid flat to the left, improving the cable winding quality and the neatness of the winding.

[0049] Furthermore, as the slider 421 slides to the right, the tension of the cable is relatively low, which will cause the tension wheel 414 and the tension rod 413 to rotate to the right, thus avoiding pulling on the cable.

[0050] In addition, as the take-up reel 6 continues to wind, the winding radius on the surface of the take-up reel 6 gradually increases, and the length of one inner turn also increases. At this time, the cable will gradually drive the tension wheel 414 and the tension rod 413 to rotate to the right, thereby making the cable distance between the second pulley 412 and the third pulley 422 gradually shorter.

[0051] The working principle of this utility model is as follows: By installing the equipment housing 1 on the left side of the stranding reel, the cable portion after stranding is inserted into the equipment housing 1. During the winding process, the drive motor 12 drives the first guide shaft 52, the second guide shaft 53, and the guide frame 5 to rotate in the opposite direction of the stranding reel, which, together with the stranding reel, tightens the cable, effectively improving the tightness of the connection between multiple sets of metal wires in the cable and improving the cable stranding quality. At the same time, the traction component 3 is used to pull the cable and press it again, further improving the cable quality. In addition, the pulley group 4 is used to adjust the winding position of the cable, effectively improving the winding quality.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
