Description

Technical Field

[0001] This utility model relates to the field of cable stranding machine technology, specifically to an elastic anti-tangle guide wheel structure for a cable stranding machine. Background Technology

[0002] When a cable needs to carry a large current, the diameter of the cable core will be relatively large. In normal production and use, due to limitations in materials and manufacturing processes, the core of a large-diameter cable is not a single, large-diameter core, but rather composed of multiple strands twisted together. Some cables require only one twisting of multiple strands, while others require multiple twistings.

[0003] A stranding positioning device for irregularly shaped conductor cables is disclosed in CN204288955U. Its features include: a central rotating shaft on the stranding machine, with 2-6 stranding plates sequentially mounted on the central rotating shaft; a wire guide module on one side of the stranding machine; and a corresponding mounting and positioning mechanism on the stranding plate closest to the wire guide module. In use, irregularly shaped transition guide rollers and tension adjustment devices are installed on the stranding plates to correct individual wires and eliminate stress. Flexible wire guide modules are evenly distributed on the four stranding plates. The mounting and positioning mechanisms corresponding to the wire guide modules on the stranding plates can adjust the angle of wires of different specifications and the tightness of the contact surface between the irregularly shaped wire and the module, thereby achieving the function of positioning the irregularly shaped wire angle. Using this irregularly shaped conductor positioning device, the fill factor reaches 96%-98%, eliminating the need for compression and thus avoiding pull-out hardening. When producing cables of the same specifications and performance, the outer diameter is reduced by 15% and the weight by more than 10%, achieving structural stability, energy saving, and convenient construction.

[0004] The aforementioned stranding positioning device for irregularly shaped conductor cables incorporates an irregularly shaped wire separating plate. This device, by using an irregularly shaped positioning mechanism, can effectively and accurately position the cable bundle, thereby avoiding the problem of tangling between the bundles. However, when this positioning device performs wire separating and opening / closing operations on the bundle, the distance is directly affected by the diameter of the wire separating plate. Specifically, when the diameter of the wire separating plate is larger, the opening / closing distance between the guide roller assemblies will be correspondingly larger; conversely, if the diameter of the wire separating plate is smaller, the opening / closing distance between the guide roller assemblies will also decrease. Therefore, to achieve flexible adjustment of the bundle separation distance, typically... Multiple sets of wire separating plates of different diameters are required, further increasing the footprint of the stranding machine and the complexity of its structure. In actual operation, if the wire harness is separated by a small distance, it may loosen and become tangled once the tension decreases. To avoid this, the operator needs to repeatedly adjust the tension of the guide wheel assembly according to the specific situation. However, it is not convenient to immediately enter the tension adjustment stage when the stranding machine is running, as this requires stopping the stranding of the cable harness. Doing so will affect the stranding efficiency of the machine, thereby reducing production efficiency.

[0005] Therefore, those skilled in the art have provided an elastic anti-winding guide wheel structure for a cable stranding machine to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide an elastic anti-tangle guide wheel structure for a cable stranding machine, so as to solve the problem mentioned in the background art that the existing cable stranding machine is not conducive to adjusting the opening and closing distance of the wire harness.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cable stranding machine elastic anti-tangle guide wheel structure includes: a wire-separating guide wheel assembly, wherein a wire-separating wheel is installed in the middle of the surface of the wire-separating guide wheel assembly, and a positioning guide wheel is installed on the outer edge of the wire-separating guide wheel assembly; a mounting bracket is fixedly installed at the bottom of the wire-separating guide wheel assembly, and a drive motor is installed at the end of the mounting bracket away from the center of the wire-separating guide wheel assembly; a rocker arm is fixedly connected to the output shaft of the drive motor; a tension spring is connected between the rocker arm and the wire-separating guide wheel assembly; a connecting angle bracket is fixedly installed at the end of the rocker arm away from the drive motor; and a wire-passing hole is provided inside the surface of the connecting angle bracket.

[0009] As a further embodiment of this utility model: a connecting shaft is connected to the outside of the thread hole, and a pressure hook is connected to the surface of the connecting shaft, and a torsion spring is provided between the pressure hook and the connecting shaft.

[0010] As a further embodiment of this utility model: the swing arm and the mounting frame are rotatably connected, and the swing arm and the mounting frame are arranged in a ring about the symmetrical center line of the dividing guide wheel assembly.

[0011] As a further embodiment of this utility model: the positioning guide wheel and the dividing wheel are located on the same straight line, and both the positioning guide wheel and the dividing wheel are arranged in a ring about the symmetrical center line of the dividing guide wheel assembly.

[0012] As a further improvement of this utility model: a connecting frame is rotatably mounted on the surface of the positioning guide wheel, and a pressure wheel is rotatably mounted on the inner left side wall of the connecting frame.

[0013] As a further embodiment of this utility model: the surface of the connecting frame and the dividing guide wheel assembly is fixedly connected, and the positioning guide wheel and the connecting frame form a rotating structure, and the diameter of the pressure wheel is smaller than the diameter of the positioning guide wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] On the surface of the cable distribution guide wheel assembly, from the center outwards, a cable distribution wheel and a positioning guide wheel are installed sequentially. The cable distribution wheel and the positioning guide wheel are on the same straight line and have the same structure. Their main function is to split the cable, that is, to separate the cable bundle from the middle and spread it outwards to both sides, thereby effectively avoiding the problem of cables tangling. At the bottom of the cable distribution guide wheel assembly, a swing arm is mounted on a mounting bracket. A connecting angle bracket is fixedly installed at the front end of the swing arm. After the cable bundle passes through the inside of the positioning guide wheel, it continues to pass through the wire hole on the connecting angle bracket. Through the coordinated work of the swing arm and the connecting angle bracket, the extended part of the cable is further opened and separated outwards, thus increasing the opening and closing distance between the cables and effectively preventing the cables from tangling due to being too close together. In addition, one end of the swing arm is connected to a drive motor, which can... The drive motor rotates the swing arm. When the swing arm rotates outward, the connecting angle code moves away from the outer edge of the cable guide wheel assembly. During this movement, the motor combs the cable, helping to further separate it. By adjusting the rotation angle of the swing arm, the opening and closing distance of the cable can be flexibly adjusted to adapt to different cable stranding conditions. The rotation of the drive motor makes the adjustment of the swing arm very flexible, allowing for elastic adjustment based on the actual cable stranding conditions. When the cable tension decreases, the swing arm rotates outward; when the cable tension is maintained, the swing arm maintains its original angle. When the cable tension is too high, the swing arm retracts. The entire adjustment process allows for flexible adjustment of the swing arm angle based on the actual stranding conditions. This makes the adjustment process more flexible and eliminates the need to stop the stranding machine midway for adjustment, thus avoiding adverse effects on cable stranding efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides an elastic anti-tangle guide wheel structure for a cable stranding machine, comprising: a wire-separating guide wheel assembly 1, a wire-separating wheel 2 installed in the middle of the surface of the wire-separating guide wheel assembly 1, and a positioning guide wheel 3 installed on the outer edge of the wire-separating guide wheel assembly 1. The positioning guide wheel 3 and the wire-separating wheel 2 are located on the same straight line, and the positioning guide wheel 3 and the wire-separating wheel 2 are both distributed in a ring about the symmetrical center line of the wire-separating guide wheel assembly 1. A connecting frame 8 is rotatably installed on the surface of the positioning guide wheel 3, and a pressure wheel 9 is rotatably installed on the left inner wall of the connecting frame 8. The connecting frame 8 and the surface of the wire-separating guide wheel assembly 1 are fixedly connected, and the positioning guide wheel 3 and the connecting frame 8 form a rotating structure. The diameter of the pressure wheel 9 is smaller than the diameter of the positioning guide wheel 3.

[0024] Specifically, the positioning guide wheel 3 is installed on the outer edge of the branching guide wheel assembly 1 via the connecting frame 8, and the single positioning guide wheel 3 and the single branching wheel 2 are located in the same straight line position. In this way, after a single cable passes through the branching wheel 2, it will enter the positioning guide wheel 3 through the same path. The positioning guide wheel 3 and the branching wheel 2 cooperate to position the single cable. The circular arrangement of the positioning guide wheel 3 and the branching wheel 2 is beneficial for the branching and positioning of multiple cables and avoids the cables from tangling. A pressure wheel 9 is set on the outer side of the positioning guide wheel 3. The diameter of the pressure wheel 9 is smaller than the diameter of the positioning guide wheel 3. The groove on the surface of the positioning guide wheel 3 and the groove on the surface of the pressure wheel 9 cooperate with each other. A single cable passes between the pressure wheel 9 and the positioning guide wheel 3. The pressure wheel 9 and the positioning guide wheel 3 are used to position the cable. During the twisting process, the cable will be pulled outward continuously. During the outward pulling of the cable, the pressure wheel 9 and the positioning guide wheel 3 will be pulled and rolled. During the rolling process, friction is generated with the cable, which helps to pull the cable outward. After the cable passes through the positioning guide wheel 3 and the pressure wheel 9, it immediately passes through the wire hole 10 on the surface of the connecting angle bracket 7. The wire hole 10 is used to connect the cable to the swing rod 6.

[0025] A mounting bracket 4 is fixedly installed at the bottom of the wire guide wheel assembly 1, and a drive motor 5 is installed at the end of the mounting bracket 4 away from the center of the wire guide wheel assembly 1. The output shaft of the drive motor 5 is fixedly connected to a rocker arm 6. A tension spring 14 is connected between the rocker arm 6 and the wire guide wheel assembly 1. A connecting bracket 7 is fixedly installed at the end of the rocker arm 6 away from the drive motor 5. A wire hole 10 is provided inside the surface of the connecting bracket 7. A connecting shaft 11 is connected to the outside of the wire hole 10. A pressure hook 12 is connected to the surface of the connecting shaft 11. A torsion spring 13 is provided between the pressure hook 12 and the connecting shaft 11. The rocker arm 6 and the mounting bracket 4 are rotatably connected, and the rocker arm 6 and the mounting bracket 4 are arranged in a ring about the symmetrical center line of the wire guide wheel assembly 1.

[0026] Specifically, the swing arm 6 is driven to rotate by the drive motor 5. The swing arm 6 rotates around one end of the mounting bracket 4 as the center point. During the rotation, the swing arm 6 gradually moves away from and closer to the cable guide wheel assembly 1. A connecting angle bracket 7 is fixedly installed at one end of the swing arm 6. The cable passes through the wire hole 10 in the connecting angle bracket 7. The rotation of the swing arm 6 pulls the cable outward, increasing the opening angle between the cables and preventing them from getting too close and tangling. At the same time, the drive motor 5 drives the swing arm 6 to rotate. According to the tangling of the cable, the swing arm 6 is driven to rotate and adjust. The process is highly adjustable, and the rotation of the swing arm 6 can be flexibly adjusted at any time according to the actual situation, whether it is close or far. Furthermore, a tension spring 14 is connected between the swing arm 6 and the cable guide wheel assembly 1. As the swing arm 6 and the cable guide wheel assembly 1 are adjusted to be close or far apart, the elastic force of the tension spring 14 will pull the swing arm 6, which is conducive to the elastic reset of the swing arm 6, adjusting the distance between the cables and further improving the anti-tangling effect. In addition, a pressure hook 12 is installed on the outside of the cable hole 10. The pressure hook 12 and the connecting shaft 11 cooperate to form a rotating structure to facilitate the rotation of the pressure hook 12. At the same time, with the setting of the torsion spring 13, the elastic force of the pressure hook 12 is increased. The pressure hook 12 hooks the cable that is inserted into the cable hole 10, applying an elastic force to the cable, so that the cable is stably inserted into the cable hole 10, and the cable is prevented from shaking at the insertion end of the connecting angle bracket 7.

[0027] The working principle of this utility model is as follows:

[0028] In this invention, the drive motor 5 drives the rocker arm 6 to rotate, causing the connecting bracket 7 and the threading hole 10 to move accordingly, thereby adjusting the position and tension of the cable. After the cable is evenly separated by the splitter wheel 2, they are further guided along the path of the positioning guide wheel 3, ensuring that each cable is accurately positioned in the predetermined position, i.e., passing through the splitter wheel 2. The structural design of the splitter wheel 2 is consistent with the structural design of the positioning guide wheel 3. The single cable passes through the splitter wheel 2 and enters between the pressure wheel 9 and the positioning guide wheel 3, and then passes through and enters the threading hole 10 on the surface of the connecting bracket 7. At the same time, the cooperation between the pressure wheel 9 and the positioning guide wheel 3 not only enhances the positioning stability of the cable, but also, through rolling... The dynamic friction method helps the cable pass through the entire positioning guide wheel 3 more smoothly, reducing the resistance and wear of the cable during the stranding process. In addition, the design of this structure also fully considers the dynamic adjustment needs during the cable stranding process. Through the flexible control of the drive motor 5, the rotation angle of the swing arm 6 can be precisely adjusted, thereby achieving fine adjustment of the cable spacing to adapt to the actual stranding needs of the cable. The rotation of the swing arm 6 can be flexibly adjusted according to the actual situation, either closer or farther. As the distance between the swing arm 6 and the wire guide wheel assembly 1 is adjusted, the distance between the cables is adjusted, further improving the anti-winding effect. This effectively solves the entanglement problem during the cable stranding process and improves the quality and efficiency of cable stranding.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
