[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-12 In this embodiment of the invention, the device is placed at the inlet of the rope winding device. The rope passes through the base 4 and the annular ceramic eye 5 at the fork tooth 303. During the rope winding process, if the rope tension is too high or too low, the servo motor 2 operates, and the transmission rod 7 and transmission gear 8 drive the rotating gear 9 to rotate. The pressure plate 11 and the threaded sleeve 14 move in opposite directions at the same time, causing the fork-shaped tension control component 3 to tilt or return to center. This allows the rope at the annular ceramic eye 5 to adhere to the surface of the ceramic column 6 and adjust to either a tight or loose state, increasing or decreasing the rope tension to bring the rope to the required tension state and optimize the flatness of the fabric weaving.

[0038] When the pressure plate 11 and the threaded sleeve 14 move, the protrusions 16 on the surfaces of the pressure plate 11 and the threaded sleeve 14 will move along the track of the limiting groove 1501 at the guide plate 15 to limit the pressure plate 11 and the threaded sleeve 14.

[0039] The pressure plate 11 is connected to the fork 303 of the tension control component 3 via a connector 12 and a tower spring 13. The pressure plate 11 is disc-shaped with an annular groove on one end. The connector 12 is U-shaped with a raised columnar structure at the bottom. One end of the tower spring 13 is sleeved on the columnar structure at the bottom of the connector 12, and the other end is located in the annular groove of the disc-shaped pressure plate 11. When the transmission rod 7 rotates, the pressure plate 11 moves in the direction of the thread, pushing the tower spring 13. The tower spring 13 is pressed against the connector 12 by force, causing the tension control component 3 to tilt.

[0040] When the threaded sleeve 14 moves in the thread direction following the rotating rod 10, the protruding teeth 16 on the surface will also move with the limiting groove 1501 on one side of the guide plate 15. The threaded sleeve 14 is barrel-shaped, and the bottom is conical. The tip of the cone is provided with a magnetic block 17 and a magnetic chain of the magnetic block 17 on the bottom handle 301 of the tension control component 3.

[0041] The transmission rod 7 and the transmission gear 8 drive the rotating gear 9 to rotate. The pressure plate 11 and the threaded sleeve 14 move in opposite directions at the same time. The pressure plate 11 pushes the fork tooth 303 of the tension control component 3 to move, and the threaded sleeve 14 pulls the bottom handle 301 of the tension control component 3 to move, so that the tension control component 3 tilts as a whole, strengthening the overall control of the tension control component 3. The two-line release prevents the tension control component 3 from failing due to the disconnection of one of the connections.

[0042] The housing 1 of the device is not closed on one side and has a toothed groove on the top wall. The tension control component 3 is fork-shaped, so that the fork teeth 303 are located in the groove individually under normal conditions. The rope will not touch the ceramic column 6 when it passes through the ring ceramic eye 5. Only when the rope tension needs to be adjusted will the tension control component 3 be controlled to drive the rope to adhere to the surface of the ceramic column 6. The longer the rope is pulled by the tension adjustment component, the greater the tension.

[0043] The ceramic pillar 6 and the ring ceramic eye 5 are made of ceramic material with a smooth and burr-free surface, which avoids damage to the rope caused by friction between the ceramic pillar 6 and the ring ceramic eye 5 when winding it up.

[0044] The exposed cords of this device facilitate constant monitoring of cord transmission and tension control. Its compact size, as an external device, allows it to be used with various winding machines for tension control. Each cord operates as an independent channel, reducing entanglement with other cords. Furthermore, its separate external design facilitates future maintenance and replacement without affecting machine operation during repairs.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
