Abstract (en)

Proposed is an air knife system having an angle adjusting apparatus. When a screw shaft is rotated, a moving body is moved in a vertical direction, and an angle adjusting lever receives a moving force of the moving body through a shaft member, a rotating body, and a movable rail, so that the angle adjusting lever is rotated with respect to a pipe center. In this process, the rotating body is moved together with the moving body and is rotated around the shaft member, and the movable rail is rotated together with the rotating body and is spaced apart or is approached to the pipe center. Therefore, the angle adjusting lever rotates a first gas supply pipe, and changes a vertical angle of an air knife with respect to a plated steel sheet.
