Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and specifically to a textile yarn tension adjustment mechanism. Background Technology

[0002] Textile yarn tension adjustment mechanisms are used to control the tension of yarns during the textile process, ensuring fabric quality and production efficiency. Traditional tension adjustment methods mostly rely on mechanical devices, but these have problems such as poor adjustment accuracy and slow response. With the development of technology, automated and precise tension control systems have gradually become an important development direction for the textile industry, which can effectively improve production stability and product quality.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing yarn tension adjustment mechanism cannot adaptively fine-tune the position of the tension adjustment roller. During the textile process, the yarn tension is affected by a variety of factors. If the adjustment roller cannot adaptively fine-tune and cannot compensate for these changes in time, it will lead to large fluctuations in yarn tension. When the tension is too large or the fluctuation is severe, the yarn is prone to breakage. Broken yarn may become entangled in the equipment, causing equipment failure or safety accidents. Large tension fluctuations will cause unstable friction between the yarn and components such as the adjustment roller and the guide roller, accelerating equipment wear and shortening the service life of the equipment.

[0004] To address the aforementioned problems, this application proposes a textile yarn tension adjustment mechanism. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a textile yarn tension adjustment mechanism.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A textile yarn tension adjustment mechanism, including a base plate, and further comprising:

[0007] A tension adjustment assembly includes a support plate fixed to the top of a base plate, a limit roller rotatably connected to the top side of the support plate, a drive motor mounted on the bottom side of the support plate, a screw fixed to the output end of the drive motor, a movable seat threadedly connected to the screw, and a tension adjustment roller mounted on the movable seat.

[0008] An adaptive elastic floating assembly includes a movable block disposed within a movable seat, a fixed block fixed to the movable block, a fixed plate fixed to the movable seat, a buffer damper fixed to the fixed plate, the other end of the buffer damper fixed to the fixed block, a telescopic spring disposed on the buffer damper, a third limiting groove provided on the movable seat, and a tension adjusting roller rotatably connected to the movable block and disposed within the third limiting groove.

[0009] Preferably, a limit block is fixed on the side of the movable seat near the support plate.

[0010] When the drive motor drives the screw to rotate, causing the moving seat to move along the screw axis, the limiting block slides in the first limiting groove.

[0011] Preferably, a first limiting groove is provided on the side of the support plate near the limiting block, and the limiting block is slidably connected in the first limiting groove.

[0012] The combination of the limiting block and the first limiting groove serves to limit and guide the movement, ensuring that the moving seat can only move smoothly along the path specified by the first limiting groove, preventing it from deviating or shaking during movement, and ensuring the accuracy of tension adjustment.

[0013] Preferably, the bottom of the base plate is provided with support legs.

[0014] The support legs are located at the bottom of the base plate and mainly serve to support the entire tension adjustment mechanism. They evenly distribute the weight of the mechanism to the ground, keeping the mechanism stable during operation and preventing displacement or tipping due to external forces. This provides a stable foundation for the normal operation of the tension adjustment component and the adaptive elastic floating component.

[0015] Preferably, a roller is rotatably connected to the movable block, and a second limiting groove is provided on the side of the movable seat near the roller, with the roller disposed in the second limiting groove.

[0016] When the change in yarn tension causes the moving block to move within the moving seat, the roller rolls within the second limiting groove. The roller reduces the friction between the moving block and the moving seat, allowing the moving block to move more smoothly. At the same time, the second limiting groove limits the roller, ensuring the accuracy of the moving block's direction of movement.

[0017] Preferably, one end of the telescopic spring is fixed to the fixing block, and the other end of the telescopic spring is fixed to the fixing plate.

[0018] One end of the telescopic spring is fixed to the fixed block, and the other end is fixed to the fixed plate. When the yarn tension changes suddenly and the moving block moves, the telescopic spring will extend and retract accordingly. The telescopic spring works in conjunction with the buffer damper to buffer and adjust, maintaining the stability of the yarn tension.

[0019] The beneficial effects of this utility model are:

[0020] The yarn passes over the limit roller and tension adjusting roller. When the yarn tension needs to be adjusted, the drive motor starts, driving the screw to rotate. The movable seat, which is threadedly connected to the screw, moves along the screw axis, thereby changing the position of the tension adjusting roller and adjusting the yarn tension. During the yarn's operation, if a sudden tension change occurs, the adaptive elastic floating component comes into play. When the yarn tension suddenly increases, the tension adjusting roller is pulled, causing the movable block to move within the movable seat. Through the cooperation of buffer damping and telescopic spring, the buffer damping absorbs part of the impact force, while the telescopic spring provides buffer elasticity, allowing the tension adjusting roller to adaptively fine-tune its position and prevent the yarn from breaking due to excessive tension. If the tension suddenly decreases, the telescopic spring rebounds, pushing the tension adjusting roller to reset and maintaining stable yarn tension. Attached Figure Description

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] Reference Figures 1-3 A textile yarn tension adjustment mechanism includes a base plate 1, and further includes:

[0033] Tension adjustment assembly 2 includes a support plate 21 fixed to the top of the base plate 1. A limit roller 22 is rotatably connected to the side of the support plate 21 near the top. A drive motor 23 is installed on the side of the support plate 21 near the bottom. A screw 24 is fixed to the output end of the drive motor 23. A movable seat 25 is threadedly connected to the screw 24. A tension adjustment roller 28 is provided on the movable seat 25.

[0034] The adaptive elastic floating component 3 includes a movable block 31 disposed within a movable base 25, a fixed block 34 fixed to the movable block 31, a fixed plate 35 fixed to the movable base 25, a buffer damper 36 fixed to the fixed plate 35, the other end of the buffer damper 36 fixed to the fixed block 34, and a telescopic spring 37 disposed on the buffer damper 36. A third limiting groove 38 is provided on the movable base 25. A tension adjusting roller 28 is rotatably connected to the movable block 31 and disposed within the third limiting groove 38. The yarn passes over the limiting roller 22 and the tension adjusting roller 28. When yarn tension needs to be adjusted, the drive motor 23 starts, driving the screw 24 to rotate, and engaging the screw 24 threadedly. The connected movable seat 25 moves axially along the screw 24, thereby changing the position of the tension adjusting roller 28 and adjusting the yarn tension. During yarn operation, if a sudden tension change occurs, the adaptive elastic floating component 3 comes into play. When the yarn tension suddenly increases, the tension adjusting roller 28 is pulled, causing the movable block 31 to move within the movable seat 25. Through the cooperation of the buffer damper 36 and the telescopic spring 37, the buffer damper 36 absorbs part of the impact force, while the telescopic spring 37 provides buffer elasticity, enabling the tension adjusting roller 28 to adaptively fine-tune its position and prevent the yarn from breaking due to excessive tension. If the tension suddenly decreases, the telescopic spring 37 rebounds, pushing the tension adjusting roller 28 to reset and maintaining stable yarn tension.

[0035] Reference Figures 1-2 A limiting block 26 is fixed on the side of the movable seat 25 near the support plate 21. When the drive motor 23 drives the screw 24 to rotate, causing the movable seat 25 to move axially along the screw 24, the limiting block 26 slides in the first limiting groove 27. The support plate 21 has a first limiting groove 27 on the side near the limiting block 26. The limiting block 26 is slidably connected in the first limiting groove 27. The cooperation of the limiting block 26 and the first limiting groove 27 plays a role in limiting and guiding, ensuring that the movable seat 25 can only move smoothly along the path specified by the first limiting groove 27, avoiding deviation or shaking during movement, and ensuring the accuracy of tension adjustment. The bottom of the base plate 1 is provided with a support leg 29. The support leg 29 is located at the bottom of the base plate 1 and mainly plays the role of supporting the entire tension adjustment mechanism. It evenly distributes the weight of the mechanism to the ground, keeping the mechanism stable during operation and preventing displacement or tilting due to external forces. It provides a stable foundation for the normal operation of the tension adjustment component 2 and the adaptive elastic floating component 3.

[0036] Reference Figure 1 and Figures 3-4A roller 32 is rotatably connected to the movable block 31. A second limiting groove 33 is provided on the side of the movable seat 25 near the roller 32. The roller 32 is set in the second limiting groove 33. When the change in yarn tension causes the movable block 31 to move within the movable seat 25, the roller 32 rolls within the second limiting groove 33. The setting of the roller 32 reduces the friction between the movable block 31 and the movable seat 25, allowing the movable block 31 to move more smoothly. At the same time, the second limiting groove 33 limits the roller 32, ensuring the accuracy of the moving direction of the movable block 31. One end of the telescopic spring 37 is fixed to the fixed block 34, and the other end of the telescopic spring 37 is fixed to the fixed plate 35. When the yarn tension changes abruptly and the movable block 31 moves, the telescopic spring 37 will extend and retract accordingly. The telescopic spring 37 cooperates with the buffer damper 36 to play a buffering and adjusting role, maintaining the stability of the yarn tension.

[0037] Working principle:

[0038] When the yarn tension adjustment mechanism is running, the yarn passes through the limiting roller 22 and the tension adjusting roller 28 in sequence, forming a specific yarn path. When the yarn tension needs to be adjusted, the drive motor 23 starts, driving the screw 24 to rotate, causing the movable seat 25, which is threadedly connected to the screw 24, to move axially. During this process, the limiting block 26 slides in the first limiting groove 27 of the support plate 21, playing a limiting and guiding role to ensure that the movable seat 25 moves smoothly, thereby driving the tension adjusting roller 28 to change position. By changing the path length of the yarn passing through the limiting roller 22 and the tension adjusting roller 28, the initial adjustment of the yarn tension is achieved. The adaptive elastic floating component 3 is responsible for dealing with sudden tension changes during the yarn operation. The movable block 31 is set in the movable seat 25, and the tension adjusting roller 28 is rotatably connected to the movable block 31 and located in the third limiting groove 38 of the movable seat 25. When tension suddenly increases, the tension adjusting roller 28 is pulled and the moving block 31 moves within the moving seat 25. At this time, the roller 32 rolls within the second limiting groove 33, reducing the friction between the moving block 31 and the moving seat 25 and ensuring smooth movement. Simultaneously, the buffer damper 36 absorbs part of the impact force, and the telescopic spring 37 provides buffering force, allowing the tension adjusting roller 28 to adaptively fine-tune its position, preventing the yarn from breaking due to excessive tension. If the tension suddenly decreases, the telescopic spring 37 rebounds, pushing the tension adjusting roller 28 back to its original position, maintaining stable yarn tension. In addition, the support leg 29 at the bottom of the base plate 1 evenly distributes the weight of the mechanism to the ground, providing stable support for the entire tension adjusting mechanism and ensuring that the tension adjusting component 2 and the adaptive elastic floating component 3 operate normally on a stable basis, thereby achieving effective control of yarn tension and ensuring the stability and accuracy of yarn tension during textile production.
