Abstract
Description
Technical Field
[0001] This utility model belongs to the field of weaving machine technology, specifically a tension control structure for a garment belt weaving machine. Background Technology
[0002] In the weaving process of garment belts, the stability of yarn tension directly determines the quality of the belt. Insufficient tension leads to yarn slack, resulting in skewed patterns and deformed designs; excessive tension easily causes yarn breakage, increasing raw material waste and downtime. Currently, the tension control structure of traditional garment belt weaving machines suffers from three core problems: First, dynamic response lag—when yarn speed changes, tension adjustment cannot keep up, easily causing tension fluctuations; second, poor material adaptability—it cannot automatically match tension parameters to yarns of different elasticity and thickness, such as cotton, polyester, and spandex, requiring repeated manual adjustments; and third, mechanical wear affects accuracy—after long-term friction, tension detection errors gradually increase in components such as guide wheels and tension rods.
[0003] Meanwhile, a tension control system for a braiding machine is disclosed (announcement number CN112830340A), specifically relating to the field of braiding machine technology. The system includes a braiding machine body, with a shaftless pay-off bracket located on one side of the bottom of the body. A pay-off tension guide wheel is located at the top of the shaftless pay-off bracket. A take-up tension guide wheel is located at the top of one side of the braiding machine body, and a take-up tension weight is located on one side of the bottom of the take-up tension guide wheel. A magnetic powder clutch is located at the bottom of the braiding machine body, and a pay-off tension weight is located on one side of the bottom of the braiding machine body.
[0004] The tension control system for the aforementioned knitting machine has an overly cumbersome method for adjusting tension during use, and the error is large, which reduces work efficiency.
[0005] Therefore, a tension control structure for clothing belt weaving machines is proposed to address the above problems. Utility Model Content

[0014] Preferably, a hydraulic telescopic column is fixedly provided on the upper end face of the nut, and a wire block is fixedly provided on the upper end face of the hydraulic telescopic column, with a wire hole opened inside the wire block.
[0015] By adopting the above technical solution, the direction of the belt can be accurately guided through the wire hole and wire block, ensuring that the belt can be transmitted along the predetermined path during the weaving process, thereby improving the accuracy and quality of weaving.
[0016] Preferably, a motor is fixedly mounted on the right end face of the limiting block, a rotating shaft is fixedly mounted on the inner side of the limiting block, and a transmission roller is fixedly mounted on the inner side of the rotating shaft.

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.
[0023] The following describes an embodiment of this utility model based on its overall structure.
[0024] like Figures 1 to 4As shown, this utility model provides a tension control structure for a garment belt weaving machine, including a base plate 1. An adjusting block 7 is fixedly provided at the front end of the upper end of the base plate 1. A sliding groove 11 is provided inside the adjusting block 7. A slider 12 is slidably provided inside the sliding groove 11. A nut 9 is fixedly provided inside the slider 12. A lead screw 8 is spirally provided inside the nut 9. Through the lead screw 8 and the nut 9, the rotational motion of the lead screw 8 is converted into the linear motion of the nut 9, providing a new mechanical transmission method for tension control. Compared with the traditional tension control structure, it may be more accurate and stable. Through the adjusting block 7, the sliding groove 11, the slider 12, the nut 9 and the lead screw 8, the connection and cooperation relationship between each component is clear, which is convenient for installation and maintenance.
[0025] In this embodiment, a rotating shaft 10 is fixedly installed at the end of the lead screw 8, and the rotating shaft 10 is fixedly installed with the lead screw 8. A motor 6 is fixedly installed at the top of the lead screw 8, and the motor 6 is fixedly installed with the adjusting block 7. Through the motor 6 and the lead screw 8, automated control can be achieved. The operator only needs to control the operation of the motor 6 to accurately adjust the rotation angle and speed of the lead screw 8, thereby conveniently adjusting the position of the nut 9 and thus achieving tension control. Support frames 2 are fixedly installed on both the left and right sides of the upper end face of the base plate 1. The support frame 2 has a slide rail 13 inside, and a limit block 14 is slidably installed inside the slide rail 13. A transmission roller 5 is fixedly installed on the inner side of the support frame 2. Through the transmission roller 5, weaving quality problems caused by shaking or deviation are reduced. A hydraulic telescopic rod 15 is fixedly mounted on the upper end face of the limiting block 14, and the hydraulic telescopic rod 15 is fixedly mounted to the support frame 2. A spring 16 is fixedly mounted on the outer side of the hydraulic telescopic rod 15. Through the hydraulic telescopic rod 15, the position of the limiting block 14 can be precisely controlled according to actual needs, thereby adjusting the distance between the transmission roller 1 4 and the transmission roller 2 5, and realizing flexible adjustment of the belt tension. A hydraulic telescopic column 17 is fixedly mounted on the upper end face of the nut 9, and a guide block 18 is fixedly mounted on the upper end face of the hydraulic telescopic column 17. A guide hole 19 is opened inside the guide block 18. Through the guide hole 19 and the guide block 18, the direction of the belt can be accurately guided, ensuring that the belt can be transmitted according to the predetermined path during the weaving process, thereby improving the weaving accuracy and quality. A motor 3 is fixedly mounted on the right end face of the limiting block 14, a rotating shaft 20 is fixedly mounted on the inner side of the limiting block 14, and a transmission roller 4 is fixedly mounted on the inner side of the rotating shaft 20. The motor 3 provides an independent power source for the transmission roller 4, allowing the transmission roller 4 to be rotated independently as needed, thereby improving the flexibility and efficiency of the belt transmission.
[0026] Working principle and process of tension control structure in garment belt weaving machine: When motor 6 is started, it drives the lead screw 8 to rotate. Since the lead screw 8 and nut 9 are connected by a screw, and the slider 12 slides in the groove 11, it limits the movement of nut 9, thus converting the rotation of the lead screw 8 into the linear motion of nut 9. The rotating shaft 10 at the end of the lead screw 8 ensures the stability of the rotation. By controlling the forward and reverse rotation and the number of rotations of motor 6, the position of nut 9 on lead screw 8 can be precisely controlled, thereby adjusting the position of hydraulic telescopic column 17 and guide block 18. The guide block 18 has a guide hole 19 inside, through which the belt thread passes. Changing the position of guide block 18 can initially adjust the tension of the belt thread to adapt to the tension requirements of different weaving processes. The hydraulic telescopic column 17 can be extended and retracted according to the actual situation. When further fine-tuning of the tension is required, the extension and retraction of the hydraulic telescopic column 17 can change the height of guide block 18, thereby further adjusting the tension of the belt thread. After fine adjustments, motor 3 is started, which drives shaft 20 to rotate, which in turn drives transmission roller 4 to rotate. Transmission roller 4 and transmission roller 5 work together to realize the conveying and weaving of the waist belt thread. The limiting block 14 slides within the slide rail 13. The combination of hydraulic telescopic rod 15 and spring 16 ensures the stability and adjustability of the limiting block 14 during the transmission process. During the weaving process, when the tension of the waist belt thread changes, the hydraulic telescopic rod 15 will extend or retract according to the actual situation. For example, when the tension is too high, the hydraulic telescopic rod 15 retracts, the spring 16 is compressed, the limiting block 14 slides downward, and the position of transmission roller 4 drops, thereby reducing the tension of the waist belt thread. Conversely, when the tension is too low, the hydraulic telescopic rod 15 extends, the spring 16 returns to its original state, the limiting block 14 slides upward, and the position of transmission roller 4 rises, increasing the tension of the waist belt thread. This plays the role of the tension control structure of the garment waist belt weaving machine.
