[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: a tension adjustment structure for yarn, including a mounting box 1, a U-shaped plate 3 fixedly mounted on the front side of the top of the mounting box 1, a movable rod 9 fixedly mounted inside the U-shaped plate 3, a movable wheel 6 rotatably mounted on the surface of the movable rod 9, and the U-shaped plate 3, the movable wheel 6 and the movable rod 9 are arranged symmetrically on the left and right sides. A sliding groove 13 is opened in the middle of the top of the mounting box 1, a moving block 21 is slidably mounted inside the sliding groove 13, a movable box is fixedly mounted on the top of the moving block 21, a connecting rod 10 is fixedly mounted inside the movable box, a tensioning wheel 4 is rotatably mounted on the surface of the connecting rod 10, connecting blocks 18 are fixedly mounted on both the left and right sides of the moving block 21, sliding rods 20 are fixedly mounted on both the left and right sides inside the mounting box 1, and the connecting blocks 18 are slidably connected to the sliding rods 20. A servo motor 12 is fixedly mounted in the middle of the back of the mounting box 1, a threaded rod 19 is fixedly mounted on the output end of the servo motor 12, and the threaded rod 19 is threadedly connected to the inside of the moving block 21.

[0022] Working principle: When the device is in use, the servo motor 12 is started first, which drives the threaded rod 19 to rotate through the rotating shaft at the output end. Since the connecting block 18 is surface-movably connected to the sliding rod 20, and the moving block 21 is threadedly connected to the threaded rod 19, and the moving block 21 is internally slidably connected to the sliding groove 13, the rotation of the threaded rod 19 drives the moving block 21, the movable box, the connecting rod 10, and the tensioning wheel 4 to move back and forth. This changes the distance between the movable wheel 6 and the tensioning wheel 4, thereby adjusting the yarn tension. The number of rotations of the threaded rod 19 precisely controls the movement distance of the tensioning wheel 4, facilitating precise control of the yarn tension. The movable wheel 6 is rotatably connected to the movable rod 9, and the rotation of the tensioning wheel 4 and connecting rod 10 facilitates yarn movement, reducing friction between the yarn and the movable wheel 6 and tensioning wheel 4. The mounting bracket 7 and mounting holes 15 facilitate installation and fixation of the device, and the multiple mounting holes 15 ensure a more secure installation. The fixed handle 11 facilitates the movement of the device. The design facilitates the installation of this device. The anti-slip sleeve 14 increases the friction on the surface of the fixed handle 11, preventing slippage. The mounting plate 8 facilitates the installation of the switch button 16 and control knob 17. Since the motor controller 2 is electrically connected to the servo motor 12, and both the switch button 16 and control knob 17 are electrically connected to the motor controller 2, the switch button 16 allows the user to easily control the start and stop of the servo motor 12, while the control knob 17 allows for convenient... The user's control over the rotation direction of the servo motor 12 improves the operability of the device. The storage boxes 5, which are symmetrically arranged on the top of the mounting box 1, facilitate the storage of various parts. The anti-rust paint coating on the surfaces of the mounting box 1, U-shaped plate 3, storage boxes 5, mounting frame 7, mounting plate 8, connecting block 18, sliding rod 20, and moving block 21 prevents the device from rusting and extends its service life. All electrical equipment in this device is powered by an external power source.

[0023] In one aspect of this embodiment, the mounting plate 8 facilitates the installation of the switch button 16 and the control knob 17. Since the motor controller 2 is electrically connected to the servo motor 12, and since both the switch button 16 and the control knob 17 are electrically connected to the motor controller 2, the switch button 16 allows the user to easily control the start and stop of the servo motor 12, while the control knob 17 allows the user to easily control the rotation direction of the servo motor 12, which improves the operability of the device.

[0024] In one aspect of this embodiment, the mounting bracket 7 and mounting holes 15 facilitate the installation and fixing of the device. Since there are multiple mounting holes 15, the device can be installed more securely. The fixed handle 11 facilitates the handling of the device and makes it easier to install. The anti-slip sleeve 14 increases the friction on the surface of the fixed handle 11, making it less likely to slip when gripping.

[0025] In one aspect of this embodiment, the storage box 5 is arranged symmetrically on the top of the mounting box 1, which facilitates the storage of various parts. The anti-rust paint coating applied to the surfaces of the mounting box 1, U-shaped plate 3, storage box 5, mounting frame 7, mounting plate 8, connecting block 18, sliding rod 20 and moving block 21 makes the device less prone to rusting, which helps to extend the service life of the device.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
