ABSTRACT:
An oscillator screen cleaning apparatus includes an enclosed housing which forms a cleaning chamber having a plurality of spray nozzles positioned therein to spray a printing screen with cleaning solvent. An oscillating mechanism is mounted within the cleaning chamber to move the screen in an oscillating motion in front of the spray nozzles to provide an efficient and effective cleaning of the printing screen. The spray nozzles are arranged in two opposing grid patterns and the screen is oscillated between the grid patterns to provide complete coverage of the screen with spray cleaning solvent. The sprayed solvent is collected, filtered and resprayed onto the screen, and the high spray rate of the apparatus ensures effective cleaning with the re-used solvent. The entire spray system is enclosed within a housing which is coupled to a vapor recovery system so that solvent and solvent vapors do not escape into the environment. The apparatus provides rapid and efficient cleaning of the printing screen with cost-effective re-use of the solvent and contaminant of the solvent to produce a safer work environment.
