Traditional yarn tying machines usually use a single motor to control winding and unwinding or taking up the wire. This design may encounter the problem of unstable tension control when running at high speed.

However, this makes it difficult to achieve precise control of tiny tensions, and the devices for such tiny tension control in the prior art are relatively complex and have a relatively large structure. Therefore, it is urgent to design a winding device with a compact and simple structure to achieve controllable tiny tension on the yarn ball during the wire drawing and winding work and reduce tension fluctuations.

DETAILED DESCRIPTION
[0011] In order to make the purpose, principle and structure of the present invention more clear, it is further described below in conjunction with the drawings and specific embodiments.
[0012] Embodiment 1: The invention provides a winding device which realizes wire pay-off with small tension by rotating a wire pay-off motor.
[0013] The overall design idea is to place the pay-off motor 10, the yarn ball bearing seat shaft 21 and the yarn pay-off control unit 4 on a winding device with the winding aircraft 13 as the main body, and drive the winding device to rotate through the winding motor 3, thereby driving the yarn ball 19 to rotate accordingly. The pay-off motor 10 functions as active pay-off, and the pay-off speed is related to the pay-off length. The relationship between the pay-off tension and the pay-off speed is controlled through a closed loop.
[0014] See also Figure 1 , 2 Specifically, the frame 1 is provided with a winding motor 3 and a rotating device bracket 8, the bracket 8 is provided with a winding bearing seat 7, and the winding bearing seat 7 is sleeved with a hollow winding shaft 22. The left end of the hollow winding shaft 22 is fixedly connected with a yarn pay-off power supply and a control slip ring 5, and the right end is provided with a yarn binding mold seat 18, and the middle part of the hollow winding shaft 22 is respectively provided with a fixedly connected winding transmission wheel 6, a winding bearing seat 7 movably connected with a bearing, a fixedly connected winding aircraft 13 and a yarn ball bearing seat shaft 21 movably connected with a bearing from left to right. The yarn pay-off power supply and the control slip ring 5 can realize power supply to the pay-off motor 10 through the carbon brush method and the conduction of the hollow winding shaft 22. The winding motor pulley 2 drives the winding transmission wheel 6 to rotate through the belt, and the rotation of the winding transmission wheel 6 drives the hollow winding shaft 22 and the yarn unwinding power supply and the control slip ring 5 to rotate. Since they are all movably connected through bearings, the hollow winding shaft 22 and the winding bearing seat 7 and the yarn ball bearing seat shaft 21 can move freely without blocking each other.
[0015] The winding aircraft 13 is a cylinder body opening to the right, and the center position of the cylinder bottom of the winding aircraft 13 is fixedly connected to the hollow winding shaft 22 and rotates therewith. The cavity inside the winding aircraft 13 is provided with a yarn ball bearing seat shaft 21, a pay-off transmission wheel 11, a yarn ball shaft 15 and a yarn ball tightening mechanism 17. A plurality of yarn feeding mechanisms 16 and pay-off tension sensors 14 are symmetrically arranged along the circumference on the inner cylinder wall of the winding aircraft 13, and a pay-off motor 10 and a yarn pay-off control unit 4 are also fixedly connected to the cylinder bottom or cylinder side of the cylinder body of the winding aircraft 13, and a rotating protective cover 9 is provided along the cylinder wall toward the cylinder bottom, and the rotating protective cover 9 is used to protect the pay-off motor 10 and the yarn pay-off control unit 4 inside to prevent collision when the device rotates. The output shaft of the pay-off drive wheel 11 passes through the bottom of the winding aircraft 13 and is provided with a pay-off motor driving wheel 12. The pay-off motor driving wheel 12 and the pay-off drive wheel 11 are driven by gear meshing or belt transmission. When the hollow winding shaft 22 rotates, the winding aircraft 13 fixedly connected to the hollow winding shaft 22 is driven to rotate. The rotation of the winding aircraft 13 drives the pay-off motor 10, the pay-off drive wheel 11, the pay-off tension sensor 14, and the yarn feeding mechanism 16 to revolve relative to the hollow winding shaft 22.
[0016] The yarn ball bearing seat rotating shaft 21 is fixedly connected with a yarn ball tensioning mechanism 17. The yarn ball 19 is wound on the yarn ball rotating shaft 15. The yarn ball tensioning mechanism 17 forms a tight contact and abutment with the inner wall of the yarn ball rotating shaft 15 through a tensioning operation to form a limit. The side of the yarn ball rotating shaft 15 near the pay-off motor 10 is fixedly connected with the pay-off transmission wheel 11. The pay-off motor 10 drives the pay-off motor driving wheel 12 to rotate through the output shaft, and the pay-off motor driving wheel 12 drives the pay-off transmission wheel 11 to rotate. The pay-off transmission wheel 11 drives the yarn ball rotating shaft 15 to rotate. The yarn ball rotating shaft 15 drives the yarn ball tensioning mechanism 17 and the yarn ball bearing seat rotating shaft 21 to rotate by being pressed against the yarn ball tensioning mechanism 17. The yarn ball bearing seat rotating shaft 21 is connected to the hollow winding rotating shaft 22 by bearings, and will not drive the hollow winding rotating shaft 22 to rotate. The pay-off tension and speed are detected by the pay-off tension sensor 14 and controlled by the yarn pay-off control unit 4.
[0017] The yarn break alarm signal is output through the slip ring 5. During operation, the yarn delivery direction of the yarn ball 19 should be the same as the rotation direction of the pay-off motor 10 to achieve smooth release of the yarn. If the directions are inconsistent, it can be adjusted by changing the direction of the motor, or by changing the control mode, such as changing to a torque take-up mode. The central object, such as the copper core of the cable, enters the hollow part of the central shaft from the opening at one end of the slip ring 5 of the hollow winding shaft 22 to achieve feeding, and is sent out from the opening on one side of the yarn ball shaft 15 of the hollow winding shaft 22 to achieve discharging. The yarn ball 19 is fixed on the yarn ball rotating shaft 15 through the yarn ball tensioning mechanism 17. The yarn passes through the yarn walking mechanism 16, passes through the guide wheel of the pay-off tension sensor 14, and then passes through the exit guide wheel of the aircraft 13 to be transferred to the guide wheel of the mold seat 18. The rotation radius of the exit guide wheel of the aircraft 13 is greater than the rotation radius of the guide wheel of the mold seat 18. The mold seat 18 rotates integrally with the aircraft 13 through the hollow winding rotating shaft 22. The yarn is finally wound on the central object passing through the hollow winding rotating shaft 22 through the guide wheel on the mold seat 18. Under the action of external traction, the central object is fed and fed through the hollow shaft of the hollow winding rotating shaft 22. When the central object moves in the hollow winding rotating shaft 22, the winding motor 3 rotates and drives the yarn to wind on the central object. By changing the motor speed and the feeding speed of the central object, different winding pitches can be achieved. The central object is mostly a cable optical fiber that can pass through the hollow shaft hole. The release speed of the yarn matches the length of the winding spiral, the tension sensor 14 detects the tension and matches it with the set tension, and the yarn pay-off control unit 4 controls the device to operate under the set parameters to achieve a constant small tension on the yarn and a small fluctuation in the pay-off tension during the winding operation. The pitch of the yarn is determined by the moving speed of the central object and the winding speed, and is controlled by the electronic control system 20.
[0018] The low-power pay-off motor 10 pays off the yarn to achieve a low tension torque. The yarn ball 19 is rotated by the pay-off motor 10 installed on the aircraft 13. The low-power pay-off motor 10 actively pays off the yarn. After setting the required tension for the work, the pay-off tension sensor 14 feeds back the detection value and compares it with the set tension. The yarn pay-off control unit 4 closes the loop to control the pay-off speed and tension so that the working parameters are consistent with the set parameters. During the speed increase and decrease process and the stable operation process, the tension is set between 20G and 150G, and the tension fluctuates within 10g of the set tension. The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solutions and novel concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
