Before the welding wire is moved into the duct 52, the welding wire is moved into the outer cylinder 82 and is wound around the tension position 85 of Zhang Jintong. The fourth power device 84 drives the tensioning cylinder 83 to rotate, and the tensioning cylinder 83 drives the welding wire to move out of the outer cylinder 82.
The welding wire is wound on the tensioning position 85 of Zhang Jintong, so that when the welding wire stops moving, the welding wire is still in a tensioning state, and the tensioning mechanism 8 achieves tensioning of the welding wire.
The driving end of the fifth power device 54 is provided with a torque sensor. A standard force value is set in the torque sensor. When the force value detected by the torsion sensor is larger, it is indicated that the resistance of the welding wire is larger in the moving process, the torsion sensor sends a signal to the fourth power device 84, the power of the fourth power device 84 is increased, the fourth power device 84 drives the tensioning cylinder 83 to rotate faster, the moving speed of the welding wire is increased, and the force value detected by the torsion sensor is gradually close to the standard force value.
When the force value detected by the torsion sensor is smaller, it indicates that the resistance of the welding wire in the moving process is smaller, the torsion sensor sends a signal to the fourth power device 84, the power of the fourth power device 84 is reduced, the fourth power device 84 drives the tension cylinder 83 to slow down the rotating speed, the moving speed of the welding wire is reduced, and the force value detected by the torsion sensor gradually approaches to the standard force value.
The moving speed of the welding line is adjusted through the torque sensor of the fifth power device 54, so that the welding line can move at a constant speed, the welding line can be conveyed quantitatively when products are welded, and the conveying amount can be accurately controlled.
