[0024] Specifically, the shell 1 provides installation conditions for other structures, and the motor 6 drives the rotating column 7 to rotate. The rotating column 7 can drive the first rolling ring 8 to rotate. The first rolling ring 8 and the rubber ring 15 clamp the welding wire and convey the welding wire to a fixed direction through the rotation of the first rolling ring 8. When the first gear 10 rotates, it drives the second gear 11 to rotate. The rotation of the second gear 11 drives the first support column 12 to rotate. The first support column 12 drives the second rolling ring 9 to rotate. The second rolling ring 9 and another rubber ring 15 also play the role of conveying welding wire. The bottom of the first bearing 4 is fixedly connected to the rear side of the inside of the shell 1. The second bearing 5 provides rotation conditions for the second support column 13. The second support column 13 supports the rubber ring 15.

[0025] Reference Figure 1 The limiting assembly includes a pillar 22, the bottom of the pillar 22 is fixedly connected to one side of the lower side of the inside of the shell 1, the top of the pillar 22 is fixedly connected to the limiting tube 23, the front side of the shell 1 is provided with an inlet pipe 2, the rear side of the shell 1 is provided with an outlet pipe 3, the front side of the inside of the shell 1 is fixedly connected with a fixing block 19, the left and right ends of the fixing block 19 are provided with V-shaped grooves 18, and a wire groove 21 is provided in the middle of the V-shaped groove 18.

[0026] Specifically, the support 22 supports the limiting tube 23, the limiting tube 23 guides the welding wire to move in a fixed direction, the inlet pipe 2 allows the welding wire to enter the device, the outlet pipe 3 allows the welding wire to leave the device after entering the device, the fixed block 19 provides conditions for opening the V-shaped groove 18 and the wire groove 21, and the wire groove 21 limits the welding wire.

[0027] Reference Figure 2 The left and right sides of the shell 1 are fixedly connected with a cylinder 16, the output end of the cylinder 16 is fixedly connected with a moving block 17, and one end of the moving block 17 is fixedly connected with a wire-breaking cone 20.

[0028] Specifically, the cylinder 16 pushes the moving block 17, and the moving block 17 fixes the wire-breaking cone 20. The wire-breaking cone 20 is pushed forward by the cylinder 16 and cooperates with the V-shaped slot 18 to squeeze the welding wire, thereby achieving the effect of cutting the welding wire.

[0029] Reference Figure 3 An arc groove 14 is provided in the middle of the first rolling circle 8 and the second rolling circle 9.

[0030] Specifically, the arc groove 14 increases the friction area with the welding wire. The arc groove 14 on the first rolling ring 8 and the second rolling ring 9 have different specifications and can adapt to welding wires of different specifications.

[0031] Working principle: the welding wire is passed through the inlet pipe 2, and then passes through the wire groove 21 opened on the fixed block 19, the limiting pipe 23 fixedly connected to the pillar 22, and the gap between the rolling ring and the rubber ring 15 in sequence, and leaves the device from the outlet pipe 3. When the welding wire is used, the motor 6 is started to convey the welding wire through the rotation of the first rolling ring 8 or the second rolling ring 9. The arc groove 14 will increase the contact area between the rolling ring and the welding wire, and improve the stability during welding wire transportation. At the same time, the arc grooves 14 opened by the first rolling ring 8 and the second rolling ring 9 are different in size, and can convey welding wires of different specifications. Since the motor 6 drives the first gear 10 to rotate, the second gear 11 meshing with the first gear 10 can also rotate, so the device can output two welding wires at the same time. The wire breaking cone 20 on the front side of the device can cut the welding wire under the action of the cylinder 16, which is convenient for the operator to replace the welding wire.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
