Oscillator screen cleaning apparatus and method

摘要

An oscillator screen cleaning apparatus includes an enclosed housing which forms a cleaning chamber having a plurality of spray nozzles to spray a printing screen. An oscillating mechanism moves the screen in an oscillating motion in front of the spray nozzles for efficient and effective cleaning. Fixed guide brackets extend into the cleaning chamber from the spray nozzles to guide a screen and maintain the screen perpendicular to the spray patterns from the nozzles. The guide brackets will readily guide screens of different widths and heights without requiring constant adaptation. A reservoir is integrated with the enclosed cleaning chamber and a sloped wall captures spray from the cleaning chamber and directs it to the reservoir for recycling. A vertically oriented pump in the reservoir directs cleaning liquid to the spray nozzles and any failure of the pump is contained in the reservoir to prevent leakage. A wipe down booth is coupled to the cleaning chamber and captures excess cleaning liquid after the screen is removed from the cleaning chamber and directs to the captured liquid back into the reservoir.
