Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire processing technology, and in particular to a wire anti-tangling device. Background Technology
[0002] Currently, steel wires and other wires are wound on take-up frames for easy transportation. However, when processing wires, the wires need to be drawn from the take-up frames to the traction device. The traction device actively pulls the wires out of the take-up frames. However, since the wires are wound irregularly on the take-up frames, there is a height difference between the top and bottom of the take-up frames when the wires are released. Therefore, during the release process, the wires may become tangled or the tension may fluctuate, resulting in the wires shaking, coiling, or stretching and deformation. In addition, it can also cause uneven release speed, sudden jamming or wear of the wires during the release process. Utility Model Content
[0003] The purpose of this invention is to provide a wire anti-tangling device to solve the problems in the prior art, which can effectively prevent wire tangling and make the wire unwinding speed adaptable to the traction speed of the traction device.
[0004] This utility model provides a wire anti-tangling device, including a fixed base and a wire feeding rod. The fixed base is used to connect to a wire take-up frame, and the wire feeding rod can rotate around the axis of the fixed base, wherein:
[0005] The wire-laying rod includes a first rod body and a second rod body. The first rod body is rotatably connected to a fixed base, and the second rod body is movably disposed at the end of the first rod body away from the fixed base. The end of the second rod body away from the first rod body is provided with a first channel for the wire to pass through. The second rod body can move relative to the first rod body along the axial direction of the first rod body as the wire is pulled.
[0006] In the wire anti-tangle device described above, preferably, the fixing base is provided with a bearing, and the first rod is connected to the inner ring of the bearing.
[0007] In the wire anti-tangling device described above, preferably, the side of the first rod facing the second rod has a receiving cavity, one end of the second rod is housed in the receiving cavity, and the other end extends to the outside of the receiving cavity. An elastic element is provided in the receiving cavity, one end of the elastic element abuts against the bottom wall of the receiving cavity, and the other end abuts against the second rod.
[0008] In the wire anti-tangling device described above, preferably, the elastic element includes a spring, and a protrusion is provided at the end of the second rod facing the spring, the protrusion extending into the spring.
[0009] In the wire anti-tangling device described above, preferably, the first rod body is provided with a limiting rod for preventing the second rod body from detaching from the receiving cavity, the top of the first rod body is provided with a limiting hole, the top of the second rod body is provided with a limiting groove along the axial direction of the second rod body, and the limiting rod extends through the limiting hole into the limiting groove.
[0010] In the wire anti-tangling device described above, preferably, the first channel is provided with rotatable balls, the balls being distributed annularly at intervals along the first channel, and at least a portion of the balls extending out of the inner wall surface of the first channel.
[0011] Compared with the prior art, this utility model allows the wire-feeding rod to rotate around the axis of the fixed base, enabling it to follow the winding path of the wire and preventing the wire from tangling during the wire-feeding process. The second rod body of the wire-feeding rod can move relative to the first rod body. During the wire-feeding process, the second rod body can move within the first rod body according to the tension of the wire to adjust the total length of the wire-feeding rod, shortening the actual stretching path of the wire in real time, offsetting the distance extension caused by the height difference, thereby avoiding sudden increases in tension and preventing the wire from shaking or breaking.

[0022] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0023] See Figure 5 As shown, a wire anti-tangling device is used in conjunction with a take-up frame 40. It includes a fixed base 10 and a wire release rod 20. The fixed base 10 connects to the take-up frame 40, and the wire release rod 20 can rotate around the axis of the fixed base 10. The fixed base 10 is connected to the top of the take-up frame 40, and the wire release rod 20 is horizontally positioned on the fixed base 10. The wire is guided and released from the take-up frame 40 through the end of the wire release rod 20 by a traction device. During the wire release process, the wire is released around the direction of the take-up frame 40, and the wire release rod 20 rotates with the wire relative to the axis of the fixed base 10, thereby preventing tangling between wires and improving the wire release quality.
[0024] Because the winding of the cable on the take-up rack 40 is irregular, and the take-up rack 40 usually has a certain height, there is a height difference between the top and bottom of the cable on the take-up rack 40. Therefore, during cable release, the tension will fluctuate. When the cable at the bottom of the take-up rack 40 is released, the actual distance the cable travels to the end of the release rod 20 will be longer due to the height difference. The traditional fixed-length release rod 20 cannot adapt to this change, resulting in a sudden increase in tension, which can easily cause the cable to break. Therefore, see Figure 1-2 As shown, in this embodiment, the wire-feeding rod 20 includes a first rod body 21 and a second rod body 22. The first rod body 21 is rotatably connected to the fixed base 10, and the second rod body 22 is movably disposed at the end of the first rod body 21 opposite to the fixed base 10. The end of the second rod body 22 away from the first rod body 21 is provided with a first channel 30 for the wire to pass through. The second rod body 22 can move relative to the first rod body 21 along the axial direction of the first rod body 21 as the wire is pulled. In the embodiment provided in this application, the tension fluctuation of the wire caused by the height difference is compensated by dynamically adjusting the length of the wire-feeding rod 20, which can significantly improve the stability and reliability of the wire-feeding process. Specifically, the second rod body 22 can move along the axis of the first rod body 21. By adjusting the total length of the wire-feeding rod 20, that is, the relative position of the second rod body 22 and the first rod body 21, the actual stretching path of the wire is shortened in real time, offsetting the distance extension caused by the height difference, thereby avoiding a sudden increase in tension.
[0025] In this embodiment, see Figure 2As shown, in order to enable the wire-feeding rod 20 to rotate around the axis of the fixed base 10, a bearing 11 is provided inside the fixed base 10, and the first rod body 21 is connected to the inner ring of the bearing 11. The end of the first rod body 21 facing the fixed base 10 has a connecting part 211 coaxial with the fixed base 10. The connecting part 211 passes through the bearing 11 and is fixed to the inner ring of the bearing 11. The inner wall of the fixed base 10 is fixed to the outer ring of the bearing 11. When the wire is pulled out from the take-up frame 40, the wire-feeding rod 20 rotates relative to the fixed base 10 along the winding path of the wire, thereby preventing the wire from getting tangled during the wire-feeding process. The fixed base 10 can be connected to the top of the take-up frame 40 by means of fixing pins, etc., and is detachably connected to the take-up frame 40. Its specific structure is not limited here.
[0026] In one possible implementation, see [link to implementation details]. Figure 2 As shown, the side of the first rod 21 facing the second rod 22 has a receiving cavity 210. One end of the second rod 22 is housed within the receiving cavity 210, and the other end extends to the outside of the receiving cavity 210. An elastic element 23 is provided inside the receiving cavity 210. One end of the elastic element 23 abuts against the bottom wall of the receiving cavity 210, and the other end abuts against the second rod 22. The elastic element 23 provides active buffering and dynamic adjustment for the adjustment of the wire feeding rod 20. When the tension of the wire suddenly increases due to height difference or irregular winding, the second rod 22 compresses the elastic element 23 and slides into the receiving cavity 210. When the tension suddenly decreases, the elastic element 23 resets and pushes the second rod 22 out, compensating for wire slack and preventing slippage or accumulation.
[0027] Further, see Figure 2 As shown, the elastic element 23 includes a spring, and a protrusion 220 is provided at the end of the second rod 22 facing the spring, extending into the spring. After the protrusion 220 is inserted into the inner hole of the spring, it provides a guiding function for the spring, ensuring that the spring force is always transmitted along the axis of the wire feeding rod 20, and avoiding the second rod 22 being subjected to eccentric force due to spring misalignment, which would affect the tension control accuracy. It should be noted that in this embodiment, the spring can be set to be relatively long, with at least one-third of the second rod 22 housed in the receiving cavity 210, providing sufficient distance for dynamic wire adjustment, preventing the second rod 22 from detaching from the first rod 21. The spring is not fixedly connected to the first rod 21 and the second rod 22, which facilitates spring replacement.
[0028] Of course, to better prevent the second rod 22 from detaching from the first rod 21, see [reference needed]. Figure 1-3As shown, the first rod 21 is provided with a limiting rod 24 to prevent the second rod 22 from detaching from the receiving cavity 210. A limiting hole is formed at the top of the first rod 21, and a limiting groove 221 is formed at the top of the second rod 22 along its axial direction. The limiting rod 24 extends through the limiting hole into the limiting groove 221. When the second rod 22 moves to the point where the limiting rod 24 abuts against the groove walls on both sides of the limiting groove 221, it restricts the second rod 22 from further moving into or out of the receiving cavity 210. Simultaneously, the limiting rod 24 and the limiting groove 221 also guide the second rod 22, preventing radial displacement during movement and ensuring it can adjust with the wire tension. Furthermore, if the spring or the second rod 22 needs to be replaced, the limiting rod 24 can be removed, and the second rod 22 can be taken out of the first rod 21. It should be noted that, in order not to affect the movement of the second rod 22 within the first rod 21, the limiting rod 24 does not contact the bottom of the limiting groove 221.
[0029] See Figure 4 As shown, in this embodiment, a rotatable ball bearing 31 is provided within the first channel 30. The ball bearings 31 are distributed annularly along the first channel 30, and at least a portion of the ball bearings 31 extends beyond the inner wall surface of the first channel 30. The first channel 30 has multiple individual receiving spaces, and the ball bearings 31 are embedded within these spaces. When the wire passes through the first channel 30, the ball bearings 31 rotate, generating rolling friction with the wire, which reduces wear on the wire. It should be noted that the gap between adjacent ball bearings 31 should be smaller than the diameter of the wire. This can be achieved by using ball bearings 31 with larger diameters or increasing the number of ball bearings 31. The aim is to ensure that the wire can only move within the gaps formed by the multiple ball bearings 31, and will not get stuck between adjacent ball bearings 31.
