[0002] Braiding machines are widely used process equipment for manufacturing woven products of various materials, such as textiles, metal mesh, etc. During the operation of the braiding machine, the tension control of the pay-off is crucial, which directly affects the quality and efficiency of the woven product. If the pay-off tension is too high, it may cause the wire to break or the braided structure to be too tight; if the tension is too low, it may cause the braided structure to be loose, affecting the overall performance of the product.

[0003] Most of the existing wire pay-off tension control methods are in the form of spring plus friction plate, and the tension is mainly achieved by adjusting the compression force of the compression spring. However, during long-term use, due to the wear of the friction plate, the spring tension will deform, resulting in unstable wire pay-off tension, loose and tight wire pay-off, affecting product quality.

[0014] Preferably, the central axis of the pay-off wheel is connected to an external servo motor.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] 1) The present application uses a magnetic powder brake to achieve brake adjustment of the brake gear, which effectively solves the problem that the spring tension deformation caused by the wear of the existing friction plate leads to unstable wire tension, loose and tight wire payout, and affects product quality.

The pay-off wheel 1 and the fixed gear 2 rotate simultaneously, and the input end of the brake gear 7 is connected to the magnetic powder brake 6. The magnetic powder brake 6 can prevent the fixed gear 2 from rotating on its own, thereby ensuring the smoothness of the pay-off process.

[0026] As a preferred embodiment, the frame 4 is provided with several groups of bearing seats 5 for installing the pay-off wheel 1 and the brake gear 7. The brake gear 7 and the pay-off wheel 1 are rotatably installed on the frame 4 through the bearing seats 5. The central axis of the pay-off wheel 1 is connected to an external servo motor, and the servo motor can drive the pay-off wheel 1 to run stably at a low speed.

[0027] As a preferred method, a tension adjustment component 3 is also installed at one end of the frame 4. The braided wire head on the pay-off wheel 1 passes through the middle of the two fixed shafts 305 on the tension adjustment component 3 and then is wound around the flower wheel and the braided conductor, and then is wound around the take-up reel through the traction wheel. In this process, the braided wire can be tensioned by rotating the tension adjustment component 3. At the same time, the tension of the wire can be adjusted and controlled by the cooperation of the tension adjustment component 3 with the magnetic powder brake 6 and the brake gear 7. It can be widely used in various braiding machines and help improve the quality and efficiency of braided products.

A main shaft 301 is fixedly installed at the center of the outer ends of the two slides 303, and the main shaft 301 is connected to an external stepper motor. The stepper motor can drive the main shaft 301 to rotate forward and reverse in steps, which is convenient for the angle adjustment of the tensioning adjustment component 3.

[0030] As a preferred manner, an indicator sign 302 for indicating the position of the guide sleeve 307 is provided at the outer end of the slide 303. The indicator sign 302 can facilitate the staff to observe the position of the guide sleeve 307 in time to prevent excessive adjustment from damaging the wire.

[0031] As a preferred embodiment, a baffle 306 is fixedly provided on the outer circle of the inner wall of the slide 303, and the baffle 306 is used to prevent the guide sleeve 307 from sliding, thereby avoiding the influence of the reciprocating sliding of the guide sleeve 307 on the wire tensioning adjustment; a plurality of open grooves 304 are evenly opened on the baffle 306, and the open grooves 304 are used to discharge debris that falls into the baffle 306.
