AI Technical Summary
In the current hot-dip galvanized silicon steel sheet production process, adjusting the angle and height of the air knife is not easy, resulting in low work efficiency and difficulty in meeting different production requirements.
A closed-loop zinc coating control device for air knife, including an installation mechanism and an adjustment mechanism, was designed. Through a motor-driven lead screw and gear transmission system, combined with real-time monitoring by sensors, the air knife angle and height can be precisely adjusted.
It achieves precise control of the air knife angle and height, improves work efficiency, adapts to different production line layouts, meets diverse production needs, and ensures the best zinc coating adhesion effect.
