Abstract

A piezoelectric ink-jet printing device comprises a base plate and a piezoelectric plate. A pair of liquid drop injector rows arranged in a staggered mode are arranged on the base plate in the arranging direction. Each liquid drop injector comprises a spray hole connected with pressure chamber liquid, and a pressure chamber is defined by a side wall. A first surface of the piezoelectric plate closely abuts against the pressure chambers. An electrode layer is arranged on the second outer surface, opposite to the first surface, of the piezoelectric plate. The electrode layer comprises signal lines corresponding to the liquid drop injectors in the staggered rows, and at least one public main ground electrode, and the public main ground electrodes are connected to ground electrodes which are located on the upper portions of the pressure chambers and are aligned along the side wall. Each signal line is connected to a corresponding signal input welding disc arranged between the staggered rows. The public main ground electrodes extend in the arranging direction and are connected to a return welding disc.

Description

Technical field [0001] The invention belongs to the field of piezoelectric inkjet printing, and more specifically, relates to the structure of a piezoelectric inkjet printing device. Background technique [0002] Inkjet printing is usually done with drop-on-demand inkjet or continuous inkjet printing. In drop-on-demand inkjet printing, droplets are ejected onto the recording medium using a droplet ejector with a booster (such as thermal or piezoelectric) actuator. Selective activation of the driver causes the formation and ejection of a flying ink drop that passes through the space between the print head and the recording medium and strikes the recording medium. The formation of the printed image is achieved by controlling the formation of each droplet in accordance with the needs of the required image for printing. The desired image may include any dot pattern corresponding to the image data. It can include graphics or text images. If appropriate ink is used, it can also inc...
