[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A spiral spring winding mechanism in this embodiment includes a worktable 1, a fixed plate 2 and a stand 6 on the top of the worktable 1, a conveying assembly 3 on the front side of the fixed plate 2, the conveying assembly 3 including three active rollers 301 and three driven rollers 302, a winding assembly on the stand 6, and a power assembly 4 between the three active rollers 301.

[0022] An adjustment mechanism 5 is provided between the three driven rollers 302. The adjustment mechanism 5 includes a connecting plate 501. The connecting plate 501 is movably installed on the front side of the fixed plate 2. A screw 502 is fixedly installed on the rear side of the connecting plate 501. A sliding opening 503 is provided inside the fixed plate 2 on the outer surface of the screw 502. A nut 504 located on the rear side of the fixed plate 2 is threadedly connected to the outer surface of the screw 502.

[0023] The sliding chute 503 is adapted to the screw 502. The screw 502 can move up and down within the sliding chute 503, thereby changing the height of the connecting plate 501 and thus changing the distance between the three driven rollers 302 and the three driving rollers 301. This enables the conveying of steel wires of different thicknesses and meets the requirements for winding different types of steel wires.

[0024] The height of the screw 502 can be fixed by the nut 504, which means the height of the three driven rollers 302 can be fixed.

[0025] Two slide rails are provided on the front side wall of the fixed plate 2, and a pulley that is slidably connected to the two slide rails is fixedly installed on the rear side of the connecting plate 501. By setting the slide rails and pulleys, the stability of the connecting plate 501 when moving up and down is improved.

[0026] The power assembly 4 includes a rotating rod 401. The rear sides of the three drive rollers 301 are all fixedly installed with rotating rods 401 that pass through the fixed plate 2. The rear side of the fixed plate 2 is fixedly installed with a motor 402 connected to one of the rotating rods 401. The outer surfaces of the three rotating rods 401 are all fixedly installed with pulleys 403. A connecting belt 404 is installed between every two adjacent pulleys 403.

[0027] Under the action of the power component 4, the three active rollers 301 can be driven to rotate, providing power for the conveying of the steel wire, so that the steel wire is located between the three active rollers 301 and the three driven rollers 302, and the steel wire is conveyed to the coiling component.

[0028] The winding assembly includes an electric push rod 601. The electric push rod 601 is fixedly installed on the top of the stand 6. The lifting seat 602 is fixedly installed on the bottom of the electric push rod 601. The motor 603 is fixedly installed on the rear side of the lifting seat 602. The winding rod 604 that passes through the lifting seat 602 is fixedly installed at the output shaft of the motor 603.

[0029] The electric push rod 601 can drive the winding rod 604 to move up and down, thus facilitating the winding of the delivered steel wire.

[0030] An auxiliary mechanism 7 is provided on the workbench 1. The auxiliary mechanism 7 includes a slide groove 701. The slide groove 701 is opened at the top right end of the workbench 1. The slide groove 701 is slidably connected to a slider 702 that is fixedly installed at the bottom of the stand 6. An electric push rod 703 that is fixedly connected to the slider 702 is fixedly installed at the front right end of the workbench 1.

[0031] With the cooperation of electric push rod 703 and slider 702, when electric push rod 703 extends and retracts at a constant speed, the steel wire can be evenly wound onto the winding rod 604.

[0032] When implementing this procedure, please follow these steps:

[0033] 1) First, adjust the distance between the three active rollers 301 and the three driven rollers 302 according to the thickness of the steel wire. First, the screw 502 moves up and down in the sliding mouth 503, which drives the connecting plate 501 to move up and down. The connecting plate 501 drives the three driven rollers 302 to move up and down. After adjusting the three driven rollers 302 and the three active rollers 301 to a suitable thickness for the steel wire.

[0034] 2) Then, the motor 402 drives the rotating rod 401 connected to it to rotate. With the cooperation of three pulleys 403 and two connecting belts 404, the three rotating rods 401 rotate simultaneously, thereby driving the three active rollers 301 to rotate. At that time, the steel wire is transported to the winding assembly between the three active rollers 301 and the three driven rollers 302.

[0035] 3) Adjust the position of the winding rod 604 according to the height transmitted from the steel wire. Drive the lifting seat 602 up and down through the electric push rod 601. The lifting seat 602 drives the winding rod 604 up and down. After adjusting the winding rod 604 to a suitable height, drive the winding rod 604 to rotate and wind the steel wire through the motor 603.

[0036] 4) Finally, when adjusting the position of the steel wire wound on the winding rod 604, the electric push rod 703 drives the slider 702 to move back and forth in the slide groove 701, thereby driving the upright frame 6 to move back and forth.

[0037] In summary, this spiral spring winding mechanism, by setting the adjustment mechanism 5, can change the height of the three driven rollers 302 and adjust the distance between the three driven rollers 302 and the three driving rollers 301, thereby realizing the conveying of steel wires of different thicknesses.

[0038] Furthermore, by setting up the auxiliary mechanism 7, the position of the upright 6 on the workbench 1 can be adjusted so that the transmitted steel wire can be wound around different positions on the surface of the winding rod 604.
