Description

Technical Field

[0001] This utility model relates to the field of sewing thread production technology, specifically to a tension-controlled industrial sewing thread production device. Background Technology

[0002] As we all know, the tension of sewing thread, that is, the tensile force that the thread experiences during sewing, is directly related to the overall quality of sewing, thus affecting the efficiency of sewing and the durability of the finished product. In the existing industrial sewing thread production process, the tension control of sewing thread is an extremely critical and indispensable link.

[0003] Traditional sewing thread tension control mainly relies on manual operation and experience. However, manual control is difficult to guarantee the stability and consistency of tension, which can easily lead to problems such as loose or tight threads during sewing, affecting the sewing effect. At the same time, it requires a lot of manpower and time, reducing production efficiency and increasing production costs. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-4A tension-controlled industrial sewing thread production device includes an adjustment box 1, a control device, and a controller 2. The adjustment box 1 has a sliding cavity, and its upper side wall has a through hole communicating with the sliding cavity. The control device is located within the sliding cavity and includes a rotating rod 14, a sliding block 15, and a connecting rod 18. The rotating rod 14 passes through the sliding cavity. A first motor 4 is located on one side wall of the adjustment box 1, and the rotating rod 14 passes through this side wall and is connected to the output end of the first motor 4. The sliding block 15 is on the rotating rod 14, and the rotating rod 14 passes through the sliding block 15 and is threadedly connected to it. The sliding block 15 is fitted and slidably connected to the inner side wall of the sliding cavity. The connecting rod 18 is located at the upper end of the sliding block 15, passes through the through hole, and is slidably connected to it. A fixing plate 7 is located at the upper end of the connecting rod 18. Multiple sets of rotating shafts 11 are provided on one end of the upper sidewall of the fixed plate 7, and multiple sets of second motors 10 are provided on the bottom wall of the fixed plate 7. The rotating shafts 11 pass through the fixed plate 7 and are connected to the output ends of the corresponding second motors 10. A connecting plate 12 is provided on the upper end of the rotating shafts 11, and a fixing rod 16 is provided on the upper end of the connecting plate 12. An auxiliary ring 8 is provided on the other end of the upper sidewall of the fixed plate 7, and a tension sensor 9 is provided on the upper end of the auxiliary ring 8. The controller 2 is located on one sidewall of the adjustment box 1. The tension sensor 9, the first motor 4, and the second motor 10 are all signal-connected to the controller 2. An operation screen 3 is provided on the upper sidewall of the controller 2. The operation screen 3 is a touch screen and is signal-connected to the controller 2. The controller 2 contains a remote communication system and a storage module. Symmetrical springs 17 are provided on both sides of the fixing rod 16, and a limit plate 13 is provided on one end of each spring 17.

[0025] During use, firstly, the required spool is placed on the fixing rod 16. The springs 17 and the limiting plate 13 on both sides of the fixing rod 16 can automatically adapt to spools of different diameters, and the elastic force of the springs 17 securely fixes the spool to the fixing rod 16, ensuring that the spool will not shake or fall off during subsequent work. Next, one end of the thread is pulled out from the spool, passed through the auxiliary ring 8, and connected to the corresponding position on the sewing machine. The auxiliary ring 8 not only helps the thread to be pulled out smoothly, but also guides the thread to a certain extent, ensuring the accurate direction of the thread. Then, the required thread tension range is preset on the operation screen 3. When the thread is pulled out and sewing begins, the tension sensor 9 will detect the tension of the thread in real time. When the thread is under tension, it will cause the sensitive element (such as a strain gauge) inside the sensor to deform or generate an electrical signal change. This deformation or electrical signal change is then converted into a measurable electrical signal, which can accurately reflect the tension of the thread. The device accurately senses the tension changes of the thread during sewing and transmits this data to the controller 2 in real time. After receiving the data from the tension sensor 9, the controller 2 immediately analyzes the data and displays it on the operation screen 3. If it determines that the current thread tension does not meet the preset standard or requirements, the controller 2 will issue a command to start the first motor 4 and the second motor 10 for tension adjustment. The output of the first motor 4 drives the rotating rod 14 to rotate. Under the limit of the adjustment box 1, the sliding block 15 moves with the rotation of the rotating rod 14, driving the fixed rod 16 to move. By adjusting the position of the spool, the thread tension can be coarsely adjusted. At the same time, the output of the second motor 10 drives the rotating shaft 11 to rotate, and the fixed rod 16 and the spool rotate accordingly. By rotating the spool, the angle and position of the thread can be finely adjusted to further finely adjust the thread tension. This combination of coarse and fine adjustment allows the device to quickly and accurately achieve the required thread tension.

[0026] In actual use, stable support is required to enhance the stability of the placement plate 6. In order to meet the above requirements, in this embodiment, support rods 5 are provided at the four corners of the bottom wall of the adjustment box 1, the bottom wall of the support rods 5 is provided with the placement plate 6, and the bottom wall of the placement plate 6 is provided with anti-slip texture.

[0027] In actual use, it is necessary to further enhance the stability and anti-slip properties of the limiting plate 13. In order to meet the above requirements, in this embodiment, the limiting plate 13 is provided with anti-slip silicone around its perimeter.

[0028] In actual use, it is necessary to be able to issue an alarm in a timely manner when the equipment malfunctions or is in an abnormal state, so as to remind the operator to handle it. In order to meet the above requirements, in this embodiment, the operation panel 3 is equipped with an alarm device.

[0029] In practical use, precise tension regulation and rotation control are required. To meet the above requirements, in this embodiment, both the first motor 4 and the second motor 10 are servo motors.
