Description

Technical Field

[0001] This utility model belongs to the field of texturing machine technology, specifically a tension adjustment mechanism for yarn texturing machines. Background Technology

[0002] A texturing machine is a type of textile machinery that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium and low elasticity through false twisting. It uses physical methods to twist and heat-treat long fibers such as nylon and polyester fibers, and then re-twist them. The yarn texturing machine operates at a relatively high speed during processing, and the yarn tension is unstable. Therefore, the yarn texturing machine is equipped with a tension adjustment mechanism to adjust the yarn tension.

[0003] While existing tension adjustment mechanisms in yarn texturing machines can dynamically adjust yarn tension, they often rely on counterweights or moving traction wheels to regulate tension, and only adjust one traction wheel at a time. This results in uneven tension adjustment and poor adjustment effectiveness. Therefore, we propose a tension adjustment mechanism for yarn texturing machines. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a tension adjustment mechanism for a yarn texturing machine, which has the advantages of uniform tension adjustment of the yarn and good tension adjustment effect.

[0006] Preferably, a third support plate is fixedly provided on the upper part of the first support plate near the side end of the disk, and a stress sensor fixedly connected to the lower end of the first support rod is fixedly provided on the upper part of the third support plate.

[0007] Preferably, a second groove is provided on the slide plate, the second groove passing through the side end of the slide plate near the third support rod, and the fourth support rod slides within the second groove.

[0008] Preferably, the upper part of both the first support plate and the second support plate is provided with a third groove corresponding to the second groove, and the third grooves both transversely penetrate the first support plate and the second support plate.

[0009] Preferably, the first gear has a first groove that passes through it, and the first groove is arc-shaped. The third support rod slides within the first groove, the second groove, and the third groove.

[0010] Preferably, the output end of the motor is fixedly provided with a second support rod that is fixedly connected to the middle of the second gear.

[0011] Preferably, a roller is uniformly rotatably provided on the inner end of the arc-shaped groove plate, a groove is provided in the middle of the roller, and the surface of the roller is provided with a slope from both ends of the roller towards the groove.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a tension adjustment mechanism for a yarn texturing machine, including a base 1. A bracket 2 is welded and fixed to the upper end of the base 1. A first support plate 3 is welded and fixed to the side of the upper end of the base 1 away from the bracket 2. Second support plates 4 are symmetrically welded and fixed to the left and right sides of the first support plate 3. First support rods 6 are welded and fixed through the upper parts of the first support plate 3 and the second support plate 4. A disc body 7 is fixed to the right end of the three first support rods 6 by screws. A sliding groove plate 16 is evenly welded and fixed to the end of the disc body 7 around its circumference. A fourth support rod 17 is slidably arranged on the sliding groove plate 16. An arc-shaped groove plate 10 is welded and fixed to the end of the fourth support rod 17. A third support rod 12 for driving the fourth support rod 17 to slide is welded and fixed to the side end of the fourth support rod 17. A first gear 8 is rotatably mounted on the left end of a rod 6 via a bearing. Three first gears 8 are arranged in an equilateral triangle. All three first gears 8 are meshed with second gears 9. A motor 5 for driving the second gears 9 is fixed to the top of the bracket 2 by bolts. The output end of the motor 5 is fixed to a second rod 11 that is bolted to the middle of the second gear 9 via a spline. A second slide groove 18 is provided on the slide plate 16. The second slide groove 18 passes through the side end of the slide plate 16 near the third rod 12. The fourth rod 17 slides in the second slide groove 18. A first slide groove 15 is provided on the first gear 8 that passes through the first gear 8. The first slide groove 15 is arc-shaped. The third rod 12 slides in the first slide groove 15 and the second slide groove 18.

[0023] Among them, the electric motor 5 and the stress sensor 14 with model number TS61-410B are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0024] The yarn passes under the arc-shaped groove 10 on the second support plate 4 located to the left of the first support plate 3, then over the arc-shaped groove 10 on the first support plate 3, and finally over the arc-shaped groove 10 on the second support plate 4 located to the right of the first support plate 3. Initially, the two ends of the third support rod 12 are located in the middle of the first slide groove 15 and the second slide groove 18, respectively. After the yarn is wound, when the yarn tension is small, the yarn is in a relaxed state. When the switch is turned on, the power supply is supplied to the controller and the motor 5 through the wire, so that the motor 5 is energized and works, thereby driving the second support rod 11 to rotate, thereby driving the second gear 9 to rotate, thereby driving the three first gears 8 located on the first support plate 3 and the second support plate 4 to rotate, and then driving the third support rod 12 located in the first slide groove 15 to move away from the first support plate 11. The gear 8 slides in the direction of its center, thereby driving the fourth support rod 17 located in the slide plate 16 to slide away from the disc 7, thereby driving the arc-shaped groove plate 10 to move away from the disc 7, thus increasing the yarn tension and adjusting the yarn tension to the normal range. When the yarn tension is large, the yarn is in a taut state, and the motor 5 is started in reverse. Under the action of the above components, the arc-shaped groove plate 10 moves closer to the disc 7, thereby reducing the yarn tension and adjusting the yarn tension to the normal range. At the same time, multiple arc-shaped groove plates 10 located on the first support plate 3 and the second support plate 4, which are located on the same circumference, can be moved outward or inward, thereby making the yarn tension adjustment more uniform and improving the yarn tension adjustment effect.

[0025] Specifically, a third support plate 13 is welded and fixed to the upper part of the first support plate 3 near the side end of the disc 7. A stress sensor 14, which is fixed to the lower end of the first support rod 6 by screws, is fixed to the upper end of the third support plate 13 by screws. In this invention, the detection end of the stress sensor 14 abuts against the lower end of the first support rod 6 and can monitor the stress of the yarn on the first support rod 6. When the stress of the yarn is large, the stress of the yarn on the first support rod 6 is also large, and vice versa. The stress sensor 14 transmits the stress value of the yarn on the first support rod 6 to the control processor through a wire. After processing the stress value, the control processor controls the forward and reverse rotation of the motor 5 through the wire, thereby dynamically adjusting according to the tension of the yarn, making the yarn tension adjustment effect better.

[0026] Furthermore, both the first support plate 3 and the second support plate 4 have a third slide groove 19 corresponding to the second slide groove 18 on their upper parts. The third slide groove 19 extends laterally through the first support plate 3 and the second support plate 4. In this invention, the third slide groove 19 and the second slide groove 18 are located on the same plane, and the third support rod 12 passes through the third slide groove 19. When the first gear 8 drives the third support rod 12 to move, the third support rod 12 slides in the third slide groove 19. The setting of the third slide groove 19 can ensure the normal movement of the third support rod 12, thereby ensuring the normal sliding of the fourth support rod 17 in the slide plate 16. At the same time, the third slide groove 19 also provides a certain support for the third support rod 12. The third slide groove 19 is coated with lubricating oil, which can reduce the wear between the third support rod 12 and the third slide groove 19.

[0027] Furthermore, a roller 20 is evenly rotatably mounted on the inner end of the arc-shaped groove plate 10 via a rotating shaft. A groove 21 is formed in the middle of the roller 20, and the surface of the roller 20 has a slope that slopes from both ends of the roller 20 towards the groove 21. In this invention, the yarn passes over the arc-shaped groove plate 10 and is placed in the groove 21 on the roller 20. The roller 20 reduces friction between the yarn and the roller 20 during traction and tension adjustment, thus reducing yarn wear. The groove 21 prevents the yarn from slipping off the roller 20. The slope of the roller 20 towards the groove 21, with both ends higher than the middle, allows the yarn on the slope of the roller 20 to roll into the groove 21, further preventing the yarn from slipping off the roller 20.

[0028] It is worth noting that the outlines of the multiple arc-shaped groove plates 10 and the multiple rollers 20 are on the same circumference, and the center of the circumference where the outlines of the multiple arc-shaped groove plates 10 and the center of the circumference where the outlines of the multiple rollers 20 are located are at the same position. In this invention, the multiple arc-shaped groove plates 10 and rollers 20 are respectively located on the same circumference, and the centers of the circumferences are the same. This allows the arc-shaped groove plates 10 and rollers 20 to uniformly adjust the tension of the yarn during movement, thereby improving the tension adjustment effect on the yarn.
