[0017] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0018] The present invention provides a tension self-balancing device 300 for a yarn winding device 200 of a winding machine. Figure 1 and Figure 2 As shown, it includes a frame 100, and a yarn winding device 200 and a tension self-balancing device 300 installed on the frame 100. The yarn winding device 200 is used to install a yarn tube 400 and rotate the yarn tube 400 to wind the yarn on the yarn tube 400. The tension self-balancing device 300 is used to output a torque to balance the tension formed by the yarn winding device 200 winding the yarn to achieve tension balance, thereby ensuring that the yarn is evenly, stably and reliably wound on the yarn tube 400 of the yarn winding device 200.

[0019] Specifically, Figure 2 and Figure 3 As shown, the tension self-balancing device 300 includes a torque motor 4, a synchronous wheel 5, a fixed plate 52, a connecting rod 6, a swing arm 7 and a controller. The torque motor 4 is fixedly mounted on the rear surface of the frame 100, the synchronous wheel 5 is rotatably mounted on the rear surface of the frame 100, and the synchronous wheel 5 is connected to the output shaft of the torque motor 4 through a synchronous belt 51 to achieve linkage. The first end of the fixed plate 52 is fixedly connected to the synchronous wheel 5 and the second end thereof is hinged to the first end of the connecting rod 6. The swing arm 7 is rotatably mounted on the rear surface of the frame 100. The first end of the rotating point is hinged with the second end of the connecting rod 6, and the controller is connected to the torque motor 4 signal to drive the torque motor 4 to output torque according to a predetermined program. The tension exerted on the winding shaft 1 on different time axes under different rotation speeds and yarn conditions is calculated through simulation or experiment. The predetermined program of the controller controls the torque motor 4 to output a torque corresponding to the corresponding tension under corresponding conditions, so that the winding shaft 1 is in a balanced state. In this way, the wound yarn can be in a taut state so that the yarn can be evenly, stably and reliably wound on the yarn tube 400.

[0020] In the above scheme, preferably, the swing arm 7 is a V-shaped structure, and the winding shaft 1 and the connecting rod 6 are connected to the two ends of the V-shaped opening of the swing arm 7, and the bottom of the V-shaped swing arm 7 is the rotation point.

[0021] Specifically, Figure 1 , Figure 2 and Figure 3As shown, the yarn winding device 200 includes a winding shaft 1 and a driving motor for driving the winding shaft 1 to rotate. The winding shaft 1 can rotatably pass through the second end of the swing arm 7 relative to the rotation point and extend to the front surface of the frame 100. Preferably, the second end of the swing arm 7 is provided with a through hole for the winding shaft 1 to pass through, and a second bearing is fixedly embedded in the through hole. The winding shaft 1 is fixedly sleeved in the inner circle of the second bearing; the winding shaft 1 can rotate with the rotation of the swing arm 7, so that the position of the winding shaft 1 can be adjusted so that the wound yarn is always in a taut state, thereby ensuring the winding effect of the yarn. Preferably, the driving motor is connected to the swing arm 7; correspondingly, the frame 100 is provided with an arc groove 101 for the winding shaft 1 to slide.

[0022] The cam 8 is actuated by the engagement of the frame 100 and the guide rail 100 with the guide rail 101 in such a manner that the cam 8 can be rotated freely, and the cam 8 can be rotated with the engagement of the frame 100 and the guide rail 102.

[0023] Compared with the prior art, the present invention has a simple and reasonable structure. The tension self-balancing device can control the torque output by the torque motor through a controller according to the yarn winding degree and yarn type of the bobbin on the winding shaft, thereby adjusting the position of the winding shaft through the synchronous wheel, connecting rod and swing arm to maintain the tension balance of the winding shaft, so that the yarn can be wound on the bobbin evenly, stably and reliably.
