In the normal wire winding process, the wire winding speed of the wire winding disc and the wire outlet speed of the wire outlet of the metal wire drawing machine are in a relatively stable state, the tensioning arm 62 of the tensioning mechanism 6 is located between the upper limiting rod 81 and the lower limiting rod 82 and close to the lower limiting rod 82, and the eccentric wheel 71 and the travel switch 72 keep a relatively stable distance. When the wire winding speed of the wire winding disc is smaller than the wire outlet speed of a wire outlet of the metal wire drawing machine, the metal wire 9 is loosened, the tensioning arm 62 rotates and descends for a certain angle, the eccentric wheel 71 descends along with the rotation of the tensioning arm 62, the distance between the eccentric wheel 71 and the travel switch 72 is reduced, the travel switch 72 transmits a signal with the reduced distance to the controller to enable the wire winding motor to accelerate the wire winding, after the wire winding motor accelerates the wire winding, the eccentric wheel 71 gradually rotates and rises to the initial position along with the tensioning arm 62, the distance between the travel switch 72 and the eccentric wheel 71 returns to the initial distance, the travel switch 72 transmits a distance signal to the controller to enable the wire winding motor to return to the initial rotating speed, and the rotating speed of the wire winding; when the wire winding speed of the wire winding disc is greater than the wire outlet speed of the metal wire drawing machine, the metal wire 9 is wound, the tensioning arm 62 rotates to rise by a certain angle, the eccentric wheel 71 rotates and rises along with the tensioning arm 62, the distance between the eccentric wheel 71 and the travel switch 72 is increased, the travel switch 72 transmits a signal with the increased distance to the controller to enable the wire winding motor to reduce the speed and wind the wire, after the wire winding motor reduces the speed and winds the wire, the eccentric wheel 71 gradually rotates and falls to the initial position along with the tensioning arm 62, the distance between the travel switch 72 and the eccentric wheel 71 returns to the initial distance, the travel switch 72 transmits a distance signal to the controller to enable the wire winding motor to return to the initial rotating speed, and the rotating speed. Because the counterweight 63 on the tensioning arm 62 adjusts the tension of the metal wire 9 in the wire take-up process by the gravity of the counterweight, the tension of the metal wire 9 cannot be changed due to the change of the wire take-up speed of the take-up reel and the wire outlet speed of the metal wire drawing machine, and the metal wire 9 keeps constant tension; the automatic adjustment of the rotating speed of the wire collecting motor is realized by feeding back signals to the controller through the travel switch 72, so that the wire collecting speed of the wire collecting disc and the wire outlet speed of the metal wire drawing machine are in a relatively stable state.
