[0002] Wool sweaters are made from wool and are the most popular type of knitted sweater. They are characterized by clear stitches, a smooth surface, a rich sheen, bright colors, and a full, elastic feel. Wool yarn is the core material of wool sweaters, and its performance directly affects the quality and comfort of the finished garment.

[0003] In the production of wool sweaters, the tension stability of the sewing thread directly affects the sewing quality of the sweater. If the sewing thread tension is too high, it is easy to cause the sewing thread to stretch, deform, or break, affecting the continuity of the sewing. If the tension is too low, problems such as loose sewing thread and skipped stitches will occur, reducing the sewing precision and appearance of the sweater.

[0004] Most existing thread tension adjustment devices adjust the tension using springs. However, the tension of the springs themselves is limited. When the real-time tension of the thread is greater than or less than the tension adjustment range of the spring, problems such as thread stretching and deformation, breakage, slack, or skipped stitches may occur. Therefore, a wool sweater thread tension balancing adjustment device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wool sweater seam tension balance adjustment device, which aims to solve the problem of limited tension adjustment range in existing seam tension adjustment devices.

[0018] 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.

[0019] Reference Figure 1 , Figure 3 and Figure 5The present invention provides an embodiment of a wool sweater seam tension balancing adjustment device, comprising a control base 1, a dual-response tension automatic adjustment device 2 disposed on the top of the control base 1, and a balancing component 3 disposed on the surface of the control base 1; the dual-response tension automatic adjustment device 2 includes a mounting base 21, the surface of the mounting base 21 being fixedly connected to the top of the control base 1, a control motor 22 being fixedly connected to the mounting base 21, an adjusting screw 23 being fixedly connected to the output shaft of the control motor 22, an adjusting base 24 being threadedly connected to the surface of the adjusting screw 23, and a tension adjusting component 25 disposed on the adjusting base 24; the end of the adjusting screw 23 penetrates the interior of the control base 1 and is fixedly... A connecting plate 26 is fixedly connected to the surface of the control base 1, and one side of the adjusting base 24 is slidably connected to the surface of the control base 1. A tension stabilizing disc 5 is fixedly connected to the surface of the control base 1, and multiple guide rollers 6 are fixedly connected to the control base 1. When the tension value deviates from the preset range, the control motor 22 starts and drives the adjusting screw 23 to rotate. The adjusting screw 23 drives the adjusting base 24 to slide along the surface of the control base 1. By adjusting the position of the tension adjusting component 25, the degree and position of the spring extension and contraction are changed, thereby achieving the effect of automatically adjusting the sewing tension. The tension value adjustment range is increased within the tension adjustment range of the spring itself.

[0020] Reference Figures 2-3 The tension adjustment component 25 includes a damper 251. One end of the damper 251 is fixedly connected to the adjustment base 24, and the other end of the damper 251 is fixedly connected to a connecting plate 252. A tension spring 253 is fixedly connected to the end of the connecting plate 252. The damper 251 and the tension spring 253 cooperate to effectively buffer tension fluctuations, improve the stability of tension adjustment, and prevent the sewing thread from breaking or loosening due to sudden tension changes. A connecting block 254 is fixedly connected to the end of the tension spring 253. According to the sewing thread specifications of the sweater to be processed, the initial extension and contraction of the tension spring 253 is adjusted by preset tension range through the control module so that the initial tension of the balance component 3 is at the midpoint of the preset range.

[0021] Reference Figure 4 The balancing assembly 3 includes a rotating shaft 31, the end of which is rotatably connected to the control base 1. A tension handle 32 is fixedly connected to the surface of the rotating shaft 31, and a connecting sleeve 33 is fixedly connected to the surface of the tension handle 32. A tension guide wheel 34 is fixedly connected to the end of the tension handle 32, and a pressure sensor 35 is fixedly connected inside the tension guide wheel 34. The tension is automatically adjusted by controlling the motor 22 and the adjusting screw 23. With the real-time monitoring of the pressure sensor 35, the adjustment accuracy is higher, meeting the needs of fine production of wool sweaters. A hinge shaft 331 is fixedly connected to the connecting sleeve 33. A hole and slot corresponding to the hinge shaft 331 are opened on the connecting block 254. The connecting sleeve 33 is hinged to the hole and slot on the connecting block 254 through the hinge shaft 331.

[0022] The pressure sensor 35 inside the tension guide wheel 34 detects the pressure value of the sewing thread in real time and transmits the data to the control module in real time. When the pressure sensor 35 detects that the tension value is lower than the preset lower limit, the control module sends a signal to start the control motor 22. The control motor 22 drives the adjusting screw 23 to rotate clockwise, causing the adjusting base 24 to slide upward along the linear guide rail. The adjusting base 24 pulls the damper 251 and the connecting plate 252 to move, causing the tension spring 253 to stretch. Through the hinge shaft 331, it drives the connecting sleeve 33 and the tension handle 32 to rotate around the rotating shaft 31, increasing the pressure of the tension guide wheel 34 on the sewing thread until the tension value returns to the preset range. The control motor 22 then stops working. When the pressure sensor 35 detects that the tension value is higher than the preset upper limit, the control motor 22 rotates in the opposite direction, the adjusting base 24 slides downward, the tension spring 253 contracts, and the pressure of the tension guide wheel 34 on the sewing thread decreases, realizing the reverse adjustment of tension. During this process, the damper 251 slowly releases or absorbs energy to avoid the tension spring 253 from rapidly expanding and contracting, which would cause a sudden change in tension.

[0023] Reference Figure 2 An alarm button 4 is fixedly connected to the surface of the control base 1, and a linkage rod 36 is fixedly connected to the rotating shaft 31. The linkage rod 36 is used to contact the alarm button 4 to issue an over-tension warning. When the tension increases suddenly due to tangling, jamming, or other issues with the sewing thread, the pressure on the tension guide wheel 34 increases sharply, causing the tension handle 32 to rotate counterclockwise around the rotating shaft 31. The rotating shaft 31 synchronously drives the linkage rod 36 to rotate. The free end of the linkage rod 36 touches the alarm button 4 to issue a warning signal. At the same time, the control module can link the wool sweater sewing equipment to slow down or stop to avoid thread breakage or equipment damage. After receiving the warning, the operator can stop the machine to check the sewing thread feeding path and eliminate tangling, jamming, and other faults. After the fault is eliminated, the alarm button 4 is reset, and the device returns to normal operation. By providing an over-tension warning function and using the cooperation of the linkage rod 36 and the alarm button 4, abnormal tension can be detected in time and the operator can be alerted, reducing the occurrence of batch product quality problems.

[0024] Working principle: The suture passes sequentially through the guide roller 6 and the tension stabilizing disc 5, and finally wraps around the tension guide wheel 34. The guide roller 6 and the tension stabilizing disc 5 guide the direction of the suture and buffer tension fluctuations. The pressure sensor 35 inside the tension guide wheel 34 detects the tension value of the suture in real time. When the tension value deviates from the preset range, the control motor 22 starts and drives the adjusting screw 23 to rotate. The adjusting screw 23 drives the adjusting base 24 to slide along the surface of the control base 1. By adjusting the position of the tension adjusting component 25, the extension and contraction of the tension spring 253 is changed, thereby adjusting the tension of the suture. The damper 251 can prevent violent fluctuations during the tension adjustment process. When the sewing tension is too high, the pressure on the tension guide wheel 34 increases, causing the tension handle 32 to rotate around the shaft 31. The connecting rod 36 on the shaft 31 rotates accordingly and touches the alarm button 4, triggering the warning function and reminding the operator to handle it in time. During the operation, the pressure sensor 35 and the control motor 22 achieve precise automatic adjustment of tension through closed-loop control. With the buffering effect of the damper 251, the problem of low adjustment accuracy and poor stability of traditional devices is effectively solved. At the same time, the tension warning function can handle abnormal situations in time, further ensuring the sewing quality of wool sweaters. It is suitable for large-scale and refined wool sweater production scenarios.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
