The top of the piston rod of the electric push rod 13 is connected to the outer wall of one side of the truss 10. When controlling the spacing between the rubber wheel 12 and the wire feeding wheel 7, the electric push rod 13 pulls the truss 10, the U-shaped seat 11, and the rubber wheel 12 toward the wire feeding wheel 7, so that it is suitable for feeding welding wires of different specifications; by adjusting the spacing between the wire feeding wheel 7 and the rubber wheel 12, it can be ensured that the contact area and contact pressure between the welding wire and the wire feeding wheel 7 are adapted to welding wires of different specifications, thereby reducing the wear of the welding wire;

[0023] The truss 10 and the U-shaped seat 11 are made of aluminum alloy. Compared with traditional steel, the density of aluminum alloy is smaller, so the weight of the entire structure can be reduced by making components of the same size with aluminum alloy.

[0024] The double-pulley transmission structure 5 includes two driven wheels 1 installed at one end of the surface of the main feed shaft 3, and a driven wheel 2 installed at one end of the surface of the auxiliary feed shaft 4.

The spacing between the wires can be adjusted to realize the rapid adjustment of the wire diameter specifications. After the welding wire is clamped, the staff turns on the servo motor 2 through the PLC control panel 9, and the rotational power of the servo motor 2 is transmitted to the main feed shaft 3 and the auxiliary feed shaft 4, and then the wire feeding wheel 7 rotates synchronously to realize the normal feeding of the welding wire. By adjusting the spacing between the wire feeding wheel 7 and the rubber wheel 12, it can be ensured that the welding wire is subjected to uniform force during the transportation process, avoiding the shaking or instability of the welding wire due to the uneven speed or uneven force between the wire feeding wheel 7 and the welding wire, thereby ensuring the stable feeding of the welding wire.
