    摘要: A fluid jet system for producing at least one jet drop stream includes a print head having a fluid receiving reservoir and an orifice plate provided with orifices communicating with the reservoir in such a manner that fluid supplied to the reservoir under pressure emerges from the orifices as fluid filaments. A transducer responsive to a drive signal applies vibrational energy to the orifice plate for stimulating breakup of the fluid fliaments into streams of drops of substantially uniform size and spacing. A drive circuit applies a substantially sinusoidal drive signal to the transducer for stimulating such breakup. Cleaning of the print head is accomplished by applying to the transducer a pulse train including harmonics of the sinusoidal stimulation drive signal.

    摘要: A method for cleaning nozzle surfaces of an inkjet print head assembly includes using a cleaning slide to carry out a movement along the assembly and clean the nozzle surfaces with a cleaning liquid in ultrasonic vibration. The cleaning slide includes an ultrasonic cleaning device, a suction device, and a rinsing device and the movement of the cleaning slide includes a forward movement and a backward movement. During the forward movement, the ultrasonic cleaning device and the suction device following the ultrasonic cleaning device are activated while the rinsing device following the two is deactivated. During the backward movement, the rinsing device and the suction device following the rinsing device are activated while the ultrasonic cleaning device following the two is deactivated. Cleaning liquid and contamination are advantageously prevented from reaching the interior of print heads or into an ink supply system thereof, preferably in industrial inkjet printing.

    摘要: The object is to reliably remove dirt and/or stains on the nozzle surface of a printer head. To accomplish the object, an inkjet printing device (100) is provided with a rotating brush (50) in a cap (103) mounted on a printer head (1), and a piezoelectric element (150) disposed on the side wall of the cap (103). The piezoelectric element (150) is ultrasonically vibrated at a predetermined frequency by means of a controller (20) and a power source (9). The ultrasonic vibration is transmitted into a cleaning solution in the cap (103) to remove dirt and/or stains adhered to a nozzle surface (3a). The rotating brush (50) is rotated by a motor, and its bristles (53) are vibrated by the ultrasonic vibration. Accordingly, dirt and/or stains on the nozzle surface (3a) are mechanically removed.
