[0029] Working principle: During operation, the hexagonal rotating block 14 is rotated according to the thickness of the steel strip to drive the second lead screw 13 to move the second conveyor roller 17 up and down under the action of the connecting block 15, thereby adjusting the distance between the second conveyor roller 17 and the first conveyor roller 12 to transport steel strips of different thicknesses. Then, the two steel strips to be welded are simultaneously passed between the corresponding second conveyor roller 17 and the first conveyor roller 12. Subsequently, the second motor 10 is started, driving the rotating shaft 11 to drive the first conveyor roller 12 to rotate, thereby driving the steel strips on both sides to move synchronously towards the welding gun 8. When the steel strip is transported between the corresponding two L-shaped connecting plates 27, the third motor 18 is started, driving the first bidirectional lead screw 19 to move between the first conical tooth 20 and the second conical tooth 23, and between the third conical tooth 24 and the fourth conical tooth 27. Under the meshing action of the gear 26, the second bidirectional lead screw 25 is driven to rotate synchronously through the transmission shaft 22, which in turn drives the two corresponding L-shaped connecting plates 27 on both sides to move towards each other until the contact roller 29 on the L-shaped connecting plate 27 contacts the steel strip and stops, thereby limiting the movement of the steel strip. Under the action of the second motor 10, the steel strips on both sides continue to be conveyed, and under the limiting action of the contact roller 29, the steel strips to be welded on both sides are aligned and placed directly below the welding gun 8. Then, the cylinder 2 is started, which drives the telescopic rod 3 to move the welding gun 8 downward through the connecting frame 4 to contact the aligned position of the two steel strips. Then, the welding gun 8 and the first motor 5 are started. Under the action of the first motor 5, the first lead screw 6 is driven to move the welding gun 8 back and forth along the aligned position of the steel strip through the slider 7, thereby realizing the welding operation.
