Description

Technical Field

[0001] The invention relates to the technical field of air knife baffles, in particular to an air knife baffle adjusting device. Background Art

[0002] When traditional steel strips are produced, a layer of zinc is usually plated on the surface of the steel strip. When the steel strip is pulled out of the zinc liquid pool, a fan is usually used to blow air on the surface of the steel strip to quickly cool the zinc liquid. In order to avoid the deposition of zinc liquid on the edge of the steel strip, baffles (i.e., air knife baffles) are provided on both sides of the steel strip to limit the wind force blown by the fan (i.e., air knife) so that the zinc liquid deposited on the edge of the steel strip can be blown off while cooling the zinc liquid on the surface of the steel strip. Since the distance between the air knife baffle and the edge of the steel strip is only a few millimeters, the air knife baffle needs to be replaced and cleaned in time when it becomes loose, accumulates and splashes zinc liquid, etc. to avoid collision failures. The air knife baffle follows the edge of the steel strip in the horizontal direction when working. The following device includes a measuring device and a motion device. However, due to the wear of the conveying roller of the steel strip production device, the position of the measuring device may shift and deflect during the conveying process of the steel strip. Therefore, a position adjustment device is required to adjust the air knife baffle and its measuring device during the production process. However, due to the narrow operating space, the knobs on the position adjustment device need to be set at a convenient position for adjustment. Therefore, an air knife baffle adjustment device is invented. Summary of the invention
