[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a welding machine for a steel strip.

[0033] Reference Figure 1 and Figure 2 A steel strip welding machine includes a base 1 for horizontally placing a steel strip 3, the butt joint of two adjacent steel strips 3 is a welding seam, a welding mechanism 2 is installed on the base 1, the welding mechanism 2 includes a positioning component 21, the positioning component 21 limits the steel strip 3, so that the butt joint of the steel strip 3 is aligned, the welding mechanism 2 also includes a beam 22 located above the base 1 and a spraying component 23 installed on the beam 22, the spraying component 23 quickly sprays welding powder on the welding seam, so that the weld falls on different positions of the welding seam at the same time, improves the spraying efficiency, and then improves the welding efficiency of the steel strip 3.

[0034] Reference Figure 1 The positioning assembly 21 includes a fixed plate 211 vertically fixed on the upper surface of the base 1, and the fixed plate 211 is arranged along the length direction of the base 1. A movable plate 212 is also vertically installed on the base 1. The movable plate 212 is parallel to the fixed plate 211 and arranged opposite to the fixed plate 211. When the steel strip 3 is welded, the steel strip 3 is located between the fixed plate 211 and the movable plate 212. A horizontally arranged positioning cylinder 213 is fixed on the side of the movable plate 212 away from the steel strip 3. The output end of the positioning cylinder 213 is fixedly connected to the movable plate 212, so that the movable plate 212 can slide horizontally on the base 1. The movable plate 212 is pressed against the side of the steel strip 3 by the extension and contraction of the positioning cylinder 213, so that the welding seam of the steel strip 3 is aligned.

[0035] Reference Figure 2A crossbeam 22 is horizontally arranged above the base 1, and the length direction of the crossbeam 22 is parallel to the width direction of the steel strip 3.

The hand wheel 234 has a scale line 2341, and the scale line 2341 coincides with the horizontal projection of the position of the powder trough 232. By turning the hand wheel 234, it is convenient to rotate the rotating roller 231, and it is convenient to determine the rotation position of the powder trough 232 for quantitative powder sprinkling.

[0038] A sliding opening 224 is also provided on one side of the crossbeam 22 near the hand wheel 234, and the sliding opening 224 is connected with the material discharge opening. The sliding opening 224 is located below the hand wheel 234, and a horizontally arranged positioning rod 235 is slidably installed in the sliding opening 224. The positioning rod 235 can be horizontally extended into the material discharge opening. The width of the positioning rod 235 is the same as the width of the material discharge opening. By sliding the positioning rod 235 horizontally, the material discharge length of the material discharge opening can be adjusted to meet the powder spreading work at the welding part of the steel strip 3 of different widths. When the scale line 2341 on the hand wheel 234 is aligned with the positioning rod 235, it means that the powder trough 232 is aligned with the material discharge opening.

[0042] The implementation principle of a steel strip welding machine in the embodiment of the present application is as follows:

At this time, the welding powder in the receiving groove 222 falls on the welding seam, realizing rapid and quantitative application of welding powder, and then the motor 253 drives the telescopic welding gun 256 to move along the length direction of the beam 22 to realize welding.
