[0018] Further, the adjusting mechanism comprises a connecting block, a screw rod 35, and a support, the connecting block is fixedly arranged on the bottom surface of the sliding support 36, the screw rod 35 is threadedly connected to the connecting block, one support is arranged at each end of the track B34, the screw rod 35 is rotationally connected to the two supports, and one end of the screw rod 35 is provided with a rocker.

[0019] The rocker is operated to rotate the screw rod 35, thereby driving the sliding support 36 to move along the track B34, and further adjusting the relative position between the gas knife baffle 2 and the strip steel, so that the gas knife baffle 2 and the strip steel are located in the same plane.

[0020] Further, the connecting plate B38 is provided with a waist-shaped hole A arranged in the vertical direction at the position corresponding to the bolt hole of the connecting plate A37, and the connecting plate A37 and the connecting plate B38 are connected by the bolt passing through the waist-shaped hole A and the bolt hole.

[0023] The working principle of the utility model is as follows: when the strip steel is galvanized, the strip steel adhering with zinc liquid is separated from the zinc pot through the conveying component, the air knife is arranged above the zinc pot, the air knife blows the airflow with a certain speed to the two surfaces of the strip steel to make the zinc layer on the surface of the strip steel uniformly distributed and accelerate the drying speed of the zinc liquid.

[0024] Since the blocking rod is arranged above, the zinc layer on the surface of the strip steel is basically dry, and the zinc layer will not fall off when contacting the blocking rod, therefore, the embodiment limits the distance between the air knife baffle 2 and the strip steel by the contact between the blocking rod and the two end edges of the strip steel, if the distance needs to be adjusted, only the blocking rod support needs to be moved to the specified position along the waist-shaped hole B, and then the lock bolt is locked.

[0025] Generally, the distance between the air knife baffle 2 and the strip steel is about 10mm, the strip steel is in the central position when normally running, the distance between the two ends and the air knife baffle 2 is unchanged, when the strip steel deviates to the left end, the left edge of the strip steel first pushes the whole sliding seat 33 through the left blocking rod, the sliding seat 33 drives the left air knife baffle 2 to move together, at the same time, the gas spring 32 on the side is compressed to the corresponding distance, the air knife baffle 2 on the side keeps the distance with the left edge of the strip steel during the whole deviation process, the self-adapting sliding mechanism 3 on the right side makes the right sliding seat 33 move to the left together with the strip steel through the pushing force of the gas spring 32, so that the air knife baffle 2 on the right side also keeps the distance with the right edge of the strip steel; when the strip steel returns to the normal position, the self-adapting sliding mechanism 3 on the two sides pushes the sliding seat 33 to reset through the gas spring 32, and the air knife baffle 2 also returns to the normal working position.
