Abstract: The invention discloses a wheel cleaning and blowing method. A flange plate on a sliding table I ascends from a low position to a high position, a flange plate on a sliding table II descends from a preset high position to the low position. A upper servo motor is started to drive the sliding table I and the sliding table II to move synchronously to the center, the wheel entering a cleaning system is cleaned in all directions. A lower servo motor is started to drive a rotating disk to rotate 180 degrees, the wheel enters a blowing system from the cleaning system. The upper servo motor stops working, the idle sliding table II moves to the initial position of the left station, the sliding table I moves to the initial position of the right station.
