Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of yarn dyeing tension adjustment mechanism, and in particular to an automatic tension adjustment mechanism during the yarn dyeing process. Background Technology
[0002] In the dyeing process of colored yarn, yarn tension control is a key factor in ensuring dyeing uniformity and yarn quality. Traditional tension adjustment methods often rely on manual adjustment or simple mechanical structures, making it difficult to achieve automatic and continuous tension regulation. Especially during the dyeing process, the yarn tension changes as the yarn moves and is affected by the dyeing solution. If it is not adjusted in time, it will lead to problems such as uneven dyeing and yarn breakage, seriously affecting dyeing quality and production efficiency.
[0003] In the prior art, Chinese patent document CN209973983U discloses a winding tension control mechanism for yarn dyeing. This mechanism includes a support plate, a drive mechanism, an adjustment mechanism, a fixing plate, a controller, and a guide groove. The drive mechanism, online tension sensor, and adjustment mechanism of this invention allow for tension adjustment. When tension adjustment is needed, the tension value is input to the controller, which then powers on a servo motor, driving the lead screw to move left and right. This causes the adjusting roller to apply pressure to the yarn, achieving the purpose of tension adjustment and keeping the yarn tension within a suitable range. The lead screw-driven adjustment provides fast adjustment speed, and the online tension sensor monitors the yarn tension in real time. The tension value of the yarn is fed back, and the tension value is fine-tuned by the controller to improve the accuracy of tension control. During the movement of the nut seat, the guide plate ensures that the nut seat always moves along the direction of the guide groove to avoid deflection. The slider runs in the groove of the support plate to improve the smoothness of the nut seat movement. However, consistent with conventional technology, although the adjustment speed is fast, there are problems of response lag and large adjustment step size when fine-tuning the tension, resulting in poor practicality. Therefore, this utility model discloses an automatic tension adjustment mechanism in the dyeing process of colored yarn to solve the problems of response lag and large adjustment step size in the existing tension adjustment mechanism when fine-tuning the tension.

[0023] This utility model provides, for example Figures 1 to 3An automatic tension adjustment mechanism for dyeing colored yarn, as shown, includes: a variable-diameter disc 1 with multiple sets of arc-shaped path grooves 2 arranged in an oblique array on the disc 1; an adjustment component installed on one side of the disc 1 for adjusting the tension of the colored yarn; and a support component installed on the other side of the disc 1 for winding the colored yarn. Through the cooperation of the arc-shaped path grooves 2 on the disc 1 and the adjustment rod 14, combined with the spiral design of the adjustment ramp 5 and the adjustment protrusion 8, fine adjustment of the yarn tension is achieved. This design directly transmits the adjustment force through a mechanical structure, avoiding the response lag problem of traditional drive methods and achieving higher adjustment accuracy. This solution uses simple mechanical components such as a rotating cylinder 6, an adjustment cylinder 4, and an adjustment spring 15 to achieve tension adjustment. Compared with the servo motor and screw drive mechanism in the comparative document, the structure is simpler and the failure rate is lower. Simultaneously, the sliding design of the adjustment rod 14 within the arc-shaped path groove 2 ensures the stability of the adjustment process. Tension can be quickly adjusted by rotating cylinder 6, eliminating the need for complex controller input and making operation more convenient. Furthermore, this design allows for flexible adjustments based on different yarn specifications and dyeing process requirements, by changing the diameter-changing disc 1 or adjusting the layout of the arc-shaped path groove 2, thus enhancing adaptability. The mounting arm 9, support arm 10, and winding arc plate 11 in the support assembly not only provide stable support for the yarn but also achieve orderly winding of the yarn, avoiding entanglement and breakage during dyeing, thereby improving dyeing quality and production efficiency.
[0024] Furthermore, in this example, such as Figure 1 and Figure 3As shown, the adjustment assembly includes multiple sets of adjustment rods 14. Each set of adjustment rods 14 is slidably inserted into the arc-shaped path groove 2. A through-hole is opened in the middle of the variable diameter disc 1, and a rotating cylinder 6 is rotatably installed in the through-hole. An adjustment cylinder 4 is rotatably installed on the outer wall of the rotating cylinder 6. One end of the adjustment cylinder 4 is fixedly installed on the side wall of the variable diameter disc 1. An adjustment ramp 5 is opened at the end of the adjustment cylinder 4 away from the variable diameter disc 1. A loading disc 7 is installed at the end of the rotating cylinder 6 near the adjustment ramp 5. An adjustment protrusion 8 is installed on the side wall of the loading disc 7 near the variable diameter disc 1 at the position corresponding to the adjustment ramp 5. A limit ring 16 is installed at the other end of the rotating cylinder 6, and an adjustment spring 15 is sleeved on the rotating cylinder 6. An installation disc 3 is installed on the side of the variable diameter disc 1 near the limit ring 16. One end of the adjusting spring 15 is abutted against the side wall of the mounting disc 3, and the other end of the adjusting spring 15 is abutted against the side wall of the limiting ring 16. The middle of the mounting disc 3 has a hole with the same diameter as the rotating cylinder 6, and the rotating cylinder 6 is slidably inserted into the hole. The end of the adjusting rod 14 near the loading disc 7 is equipped with a limiting block 13. The adjusting ramp 5 is spirally opened on the adjusting cylinder 4, and one end of the adjusting protrusion 8 is engaged with the adjusting ramp 5. The adjusting rod 14 is slidably inserted into the arc-shaped path groove 2 of the variable diameter disc 1. The rotating cylinder 6 passes through the middle of the adjusting cylinder 4 and connects to the middle of the variable diameter disc 1. The adjusting spring 15 is sleeved on the rotating cylinder 6, and its two ends abut against the mounting disc 3 and the limiting ring 16 respectively, ensuring stable contact between the adjusting rod 14 and the adjusting ramp 5 and the adjusting protrusion 8. When the colored yarn relaxes, the adjusting spring 15 releases pressure, causing the loading disc 7 to move towards the variable diameter disc 1. During this movement, the adjusting protrusion 8 mounted on the loading disc 7 interacts with the spirally opened adjusting ramp 5 on the adjusting cylinder 4, causing the adjusting cylinder 4 to rotate. As the adjusting cylinder 4 rotates, the adjusting protrusion 8 moves along the spiral path of the adjusting ramp 5. Simultaneously, the variable diameter disc 1 rotates, and the adjusting rod 14 slides within the arc-shaped path groove 2. The sliding motion of the adjusting rod 14 is transmitted to the winding arc plate 11 via the support arm 10, changing the winding radius of the yarn on the winding arc plate 11, thereby achieving fine adjustment of the yarn tension. The adjusting spring 15 provides continuous elasticity during the adjustment process, ensuring that the adjusting rod 14 always remains in contact with the adjusting ramp 5 and the adjusting protrusion 8, avoiding abnormal gaps during adjustment and improving the stability of the adjustment.
[0025] Furthermore, in this example, such as Figure 2 and Figure 3As shown, the support assembly includes multiple sets of mounting arms 9. The position of each set of mounting arms 9 corresponds to the position of each set of arc-shaped path grooves 2. One end of each set of mounting arms 9 is mounted on the arc wall of the mounting disc 3. A support arm 10 is slidably mounted on each set of mounting arms 9. A winding arc plate 11 is mounted on the other end of each set of support arms 10. The two adjacent sides of each set of winding arc plates 11 are connected together to form a circle. A winding groove 12 is formed on the outer wall of each set of winding arc plates 11. One end of the winding groove 12 on each set of winding arc plates 11 is connected to the winding groove 12 on the adjacent winding arc plate 11. The mounting disc 3 has a limiting groove 18 corresponding to the position of each set of adjusting rods 14, and the width of the limiting groove 18 is the same as the diameter of the adjusting rod 14. Each set of mounting arms 9 has a guide groove 17 on one side, and the guide groove 17 has the same width as the limiting groove 18. The other end of each set of adjusting rods 14 is fixedly mounted on one end of a support arm 10 inside the mounting disc 3. One end of multiple sets of mounting arms 9 is evenly mounted on the arc wall of the mounting disc 3, and a support arm 10 is slidably mounted on each set of mounting arms 9. A winding arc plate 11 is mounted on the other end of the support arm 10. Adjacent winding arc plates 11 fit together through winding grooves 12 on their outer walls. Multiple sets of winding arc plates 11 are connected together to form a circular structure, providing stable winding support for the yarn. During the yarn dyeing process, the yarn winds sequentially into the winding grooves 12 of adjacent winding arc plates 11 according to the predetermined winding path of the winding grooves 12, achieving orderly winding of the yarn. When the tension adjustment component adjusts the tension, the sliding motion of the adjusting rod 14 is transmitted to the winding arc plate 11 through the support arm 10, changing the winding radius of the yarn on the winding arc plate 11, thereby adjusting the yarn tension. This design of the support component ensures that the yarn maintains a stable winding state during the tension adjustment process, avoiding yarn entanglement and breakage.
