Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, and in particular to a multi-strand wire tension adjustment device for processing twisted wires. Background Technology

[0002] Multi-strand yarns are made by twisting and combining multiple monofilaments. If the tension of each monofilament is uneven during processing, it will lead to inconsistent tension and twist deviations in the stranded yarn, and even defects such as breakage and fuzzing, affecting strength and appearance consistency. Tension adjustment devices can balance the tension of each strand in real time, ensuring stable force during processing, and are key equipment to ensure the quality of stranding. For example, a yarn tension adjustment device disclosed in Chinese Patent No. CN222573957U has limitations in its retraction. After the device is folded and stored, some structures (such as tension rollers) still protrude from the outside of the plate due to the need to maintain basic functional shape or the constraints of the internal space of the plate, thus limiting the retraction.

[0021] Example like Figures 1 to 3As shown, this utility model proposes a multi-strand wire tension adjustment device for processing stranded wires, including a plate 1 and a multi-strand wire body 3. The multi-strand wire body 3 passes through a guide roller group 17 and a tension roller group 18, and is the object of tension adjustment. The device adjusts its tension to ensure processing quality. A receiving groove 11 is provided at the bottom of the plate 1 to receive the support rods 14 and the guide roller group 17, reducing the space occupied by the device. A pair of support rods 14 are rotatably connected to both ends inside the receiving groove 11. One end of the support rod 14 is rotatably connected to the receiving groove 11, and the other end is equipped with the guide roller group 17, supporting the guide roller group 17 and rotatably stored in the receiving groove 11. One end of each support rod 14 is provided with a guide roller group 17 for the multi-strand wire body 3 to pass through. The guide roller group 17 is installed at one end of the support rod 14 to guide the multi-strand wire body 3. A positioning groove 12 is provided in the middle of the storage groove 11 for a pair of guide roller groups 17 to be inserted. The positioning groove 12 is located in the middle of the storage groove 11 to allow the guide roller groups 17 to be inserted, thereby achieving the positioning and storage of the guide roller groups 17. A pair of support rods 14 and guide roller groups 17 are symmetrically arranged with the positioning groove 12 as the center. A mounting cover 2 is fixedly connected to the middle of one side of the plate body 1. A rotating groove 13 is provided on the top of the plate body 1. The rotating groove 13 is located on the top of the plate body 1 to provide space for the rotation of the support arm mechanism, so that the first support arm 15 and the second support arm 16 can perform opening and closing movements.

[0022] Among them, such as Figures 1 to 3 As shown, a pair of support arm mechanisms corresponding to the support rods 14 are rotatably connected inside the rotating groove 13. Each support arm mechanism includes a pair of support shafts 24 fixedly connected inside the plate 1. The support shafts 24 are fitted with first support arms 15 and gears, and rotate under the drive of the motor 21, thus moving the support arms. Symmetrically arranged first support arms 15 are fixedly fitted onto each support shaft 24. Second support arms 16 are slidably fitted onto the first support arms 15 and rotate under the drive of the drive mechanism, providing a support base for tension adjustment. The second support arm 16 is slidably fitted onto the end of the first support arm 15 away from the support shaft 24. One end of the second support arm 16 is slidably fitted onto the first support arm 15, and the other end is equipped with a tension roller group 18, whose length can be adjusted for tension regulation. Tension roller groups 18 are provided at the ends of the second support arm 16 away from the first support arm 15. The tension roller groups 18 are located at the ends of the second support arm 16. By contacting the yarn, the tension roller groups 18 adjust the resistance to the yarn during the opening and closing movement of the support arm, thereby achieving tension adjustment.

[0023] In addition, such as Figure 2As shown, a drive mechanism for opening and closing the support arm mechanism is installed inside the mounting cover 2. The drive mechanism includes a motor 21 fixedly connected inside the mounting cover 2. One end of one support shaft 24 away from the inner wall of the rotating groove 13 is fixedly connected to the output shaft of the motor 21, and the other end of the support shaft 24 away from the inner wall of the rotating groove 13 is fixedly connected to the inner wall of the mounting cover 2. A first gear 22 and a second gear 23 that mesh with each other are fixedly sleeved on the ends of the pair of support shafts 24 near the mounting cover 2. The first gear 22 and the second gear 23 are fixedly sleeved on the support shafts 24 and mesh with each other, transmitting the power of the motor 21 to the other support shaft 24, causing the two support shafts 24 to rotate in opposite directions.

[0024] It is worth noting that, such as Figure 3 As shown, the storage slot 11 has a pair of telescopic slots 111 corresponding to the other end of the support rod 14. A return spring 112 is slidably connected inside each telescopic slot 111. The return spring 112, installed inside the telescopic slot 111, pushes the telescopic locking block 113 with elastic force, locking the support rod 14 and preventing it from unscrewing out of the storage slot 11. The end of the return spring 112 away from the bottom wall of the telescopic slot 111 is fixedly connected to a telescopic locking block 113, which locks the support rod 14 out of the storage slot 11. Under the action of the return spring 112, the telescopic locking block 113 locks the support rod 14, fixing its position within the storage slot 11, preventing accidental dislodgement after storage, and ensuring the support rod 14 is securely placed after being rotated out of the storage slot 11.

[0025] Furthermore, such as Figures 1 to 2 As shown, the first support arm 15 is screwed to one end of the second support arm 16, and the end of the screw abuts against the second support arm 16. The locking screw 19 is screwed to the first support arm 15 and the end abuts against the second support arm 16, which is used to fix the relative position of the first support arm 15 and the second support arm 16.

[0026] In this embodiment, when using the multi-strand yarn tension adjustment device for twisted yarn processing, the multi-strand yarn body 3 passes through a pair of guide roller groups 17 and tension roller groups 18. The motor 21 inside the mounting cover 2 is started, and its output shaft drives the support shaft 24 to rotate. Through the meshing of the first gear 22 and the second gear 23, the other support shaft 24 rotates in the opposite direction, thereby driving the first support arm 15 and the second support arm 16 to perform opening and closing movements within the rotating groove 13. This adjusts the contact force of the tension roller group 18 with the yarn, achieving tension adjustment.

[0027] After adjusting the telescopic length of the first support arm 15 and the second support arm 16, they can be fixed by tightening the locking screw 19. To retract the first support arm 15 and the second support arm 16, simply loosen the locking screw 19 and then retract each of the second support arms 16 completely into the first support arm 15. Then, start the motor 21. Figure 1 The state shown is transformed into Figure 3 As shown in the diagram, the first support arm 15, the second support arm 16, and the tension roller group 18 can now be folded and stored. Next, the corresponding telescopic latch 113 needs to be pressed down, allowing the support rod 14 to rotate into the storage slot 11 until the guide roller group 17 at the end of each support rod 14 is fully engaged in the positioning slot 12. At this point, the telescopic latch 113 is released. The elastic thrust of the return spring 112 within the telescopic slot 111 causes the top of the telescopic latch 113 to engage with the support rod 14, preventing the support rod 14 from rotating out of the storage slot 11. This ensures that no part of the support rod 14, guide roller group 17, first support arm 15, second support arm 16, or tension roller group 18 protrudes outside the plate 1, thus reducing space occupancy.

[0028] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
