CYLINDER TYPE MULTI-NOZZLE ELECTROSTATIC INK-JET DEVICE AND INK-SPRAYING SYSTEM HAVING THE SAME

摘要

PURPOSE: A cylinder type multi-nozzle electrostatic inkjet device and an ink spraying system having the same are provided to supply ink supplied through a single supplying line to each nozzle at a same amount and pressure, thereby simply constituting the supplying line and uniformly spraying the ink through each nozzle. CONSTITUTION: A cylinder type multi-nozzle electrostatic inkjet device comprises an ink injecting pipe(110), a chamber plate(120), a nozzle holder(130), nozzles(140), a cylindrical electrode holder, and an electrode holder(150). The chamber plate is joined to the ink injecting pipe. The nozzle holder accommodates the chamber plate. A conductive ink receiving space is formed in between the nozzle holder and chamber plate. The nozzle is installed in the nozzle holder. The cylindrical electrode holder is installed in the outer circumference of the nozzle holder. The electrode holder comprises a rear electrode of a ring shape. Voltage is supplied to the ink injecting pipe and rear electrode so that electrostatic field for spraying conductive ink is formed.
