[0060] like Figure 1 - Figure 13As shown, when the spring winding device is in use, first, when the spring needs to be automatically wound by the winding device, in order to improve the effect of synchronously limiting the horizontal movement distance of the spring steel bar 17 according to the use length of the winding rod 701 when disassembling the winding rod 701 of different lengths, when the sliding card rod 703 slides out of the installation card slot 704, it will drive the connecting rod 706 to perform synchronous telescopic movement through the connection of the connecting rod 705. The movement of the connecting rod 706 causes the insertion rod 707 to slide out from the outer wall of the adjusting slider 708, so that the horizontal distance of the adjusting slider 708 on the device is adjusted, and according to the length of the winding rod 701, the adjusting slider 708 is lowered to move to the corresponding winding length, and the first electric push rod 13 is opened to drive the telescopic stop rod 710 to perform telescopic movement, so that the telescopic stop rod 710 is fitted and limited with the surface of the outer bushing 5 to prevent the outer bushing 5 from moving longer than the length of the winding rod 701, thereby reducing the spring winding quality;

[0061] Next, when the spring steel strip 17 is continuously transported and rotated by the conveying roller 10, in order to prevent the friction between the conveying roller 10 and the traditional bearing, which causes the stability of the conveying of the spring steel strip 17, and to convert and utilize the mechanical energy generated when the winding rod 701 rotates, thereby improving the energy utilization rate of the spring winding device, when the pulley group 3 rotates continuously, the rotation of the first gear 1104 drives the second gear 1105 to rotate, and the rotation of the second gear 1105 drives the connecting fan blade 1106 to rotate, so that the generated gas is transported to the air supply cavity 1108 through the air supply pipe 1102 and the air supply pipe 1101, and circulates through the air flotation hole 1109, so that the conveying roller 10 rotates in the air flotation bearing 9, thereby achieving the effect of improving the stability of continuous transportation of the spring steel strip 17 on the conveying roller 10 and improving the energy utilization rate of the winding device;

[0062] Then, the mechanical energy is further converted and utilized under the continuous rotation of the winding rod 701, and the dust adsorbed on the surface of the winding rod 701 is synchronously purged to prevent the impurities on the surface of the winding rod 701 from contacting with the spring steel bar 17, which would cause potholes on the surface of the wound spring. When airflow is generated in the connecting cylinder 1103, the airflow is transported to the purge nozzle 1203 through the solenoid valve provided outside the conversion tube 1201, and the dust adsorbed on the surface of the winding rod 701 is synchronously purged and cleaned, thereby improving the quality of the spring winding.

[0063] Finally, when the spring steel bar 17 is continuously conveyed by the conveying roller 10, in order to improve the position accuracy of the spring steel bar 17 during continuous conveying, the second electric push rod 1401 is turned on, driving the sliding block 1402 to slide synchronously along the inner wall of the connecting slide groove 1403 and the limit groove 1405, and through the rotation of the swing rod 1404, the correction frame 8 is driven to rotate synchronously, so as to achieve the effect of using angle synchronous self-correction adjustment for the correction frame 8, and the second servo motor 1801 drives the worm gear 1803 to rotate through the rotation of the worm 1802. The rotation of the worm gear 1803 drives the anti-deviation block 1805 to perform anti-deviation correction movement on the spring steel bar 17 through the rotation of the rotating rod 1804, thereby improving the effect of continuous conveying accuracy of the spring steel bar 17.
