The working principle and working process of the present invention are explained by the following embodiments

The coiled steel wire coil 7 is placed into the uncoiling mechanism 1, the quick-opening clamp 103 is loosened, the steel wire coil 7 can freely rotate in the uncoiling mechanism 1, the steel wire of the steel wire coil 7 enters the wire pressing mechanism 2 from the uncoiling mechanism 1, the adjusting bolt 207 is adjusted so as to adjust the force applied to the steel wire by the upper roller 203, the steel wire realizes shaping pre-tightening between the upper roller 203 and the lower roller 204, then the steel wire which completes shaping pre-tightening enters the tension adjusting mechanism 3, the steel wire enters from the left wheel disc 302 and is repeatedly wound on the left wheel disc 302 and the right wheel disc 303 in a splayed staggered manner, the steel wire leaves the tension adjusting mechanism 3 from the right wheel disc 303, when the steel wire leaves the tension adjusting mechanism 3, the right wheel disc 303 can be driven to rotate anticlockwise due to the friction force existing between the steel wire and the right wheel disc 303, under the condition that the left wheel disc 302 and the right wheel disc 303 can freely rotate, the tension of the steel wire is mainly the friction force applied when the steel wire drives the left wheel disc 302 and the right wheel disc 303 to rotate, thus, the tension of the steel wire is small and difficult to control, the motor reducer assembly 306 of the present invention provides a reverse rotation torque to the right wheel disc 303 to limit the right wheel disc 303 from freely rotating counterclockwise, and when the steel wire is tensioned, the reverse rotation torque of the motor reducer assembly 306 is adjusted. Tension of the steel wire which can be subjected to the P ID control in real time by the controller can be generated, wherein the rotating directions of the left wheel disc 302 and the right wheel disc 303 are opposite, and the left wheel disc 302 and the right wheel disc 303 are both power wheels, so that the friction force generated by the steel wire is doubled;

the steel wire passes through a steel wire guide wheel 403 of a tension detection device and enters the wiring mechanism 5, when the steel wire is stretched by tension, the steel wire can apply pressure to the steel wire guide wheel 403, the pressure is transmitted to a pressure sensor 404 through a bearing seat 402, the pressure sensor 404 feeds the detected pressure back to a controller in real time, so that the real-time tension value of the current steel wire is obtained, when the real-time tension value of the steel wire is larger than or smaller than a theoretical tension value, namely the steel wire tension value required by winding the surface of the rack, the controller adjusts the reverse rotation torque of the motor reducer assembly 306 after receiving the pressure detection information of the pressure sensor 404, so that the real-time tension value of the steel wire is adjusted, the adjusted real-time tension value of the steel wire is detected by the pressure sensor 404 and fed back to the controller again, and therefore closed-loop control of the controller on the steel wire tension value is achieved;

the steel wires are arranged on the outer surface of the rack through the wiring mechanism 5, and the steel wires are orderly wound on the rack by moving the position of the creel stand 501 according to needs;

the winding bracket 6 of the invention runs along the track 8, and the positive guide wheel 604 is used for running along the surface of the rack track 8; the side guide wheels 605 run along the side of the track 8 and can generate corresponding steering force along with the shape of the track 8, so that the winding device automatically turns along with the shape of the rack during running, when the winding support 6 runs on the track 8 and encounters a curve, the acting force of the driving wheels 603 and the steering guide wheels 601 on the track 8 forces the winding support 6 to deflect along with the radian of the curve, the automatic steering function of the winding support 6 is realized, and the control on the winding speed can be realized by adjusting the rotating speed of the motor speed reducer unit 602 through a frequency converter.
