DOCTORING DEVICE FOR A GRAVURE PRINTER CAPABLE OF IMPROVING THE DOCTORING PERFORMANCE AND OPERATION CONVENIENCE

摘要

PURPOSE: A doctoring device for a gravure printer is provided to obtain a uniform doctoring quality as the position of a doctor unit is controlled by operating each driving unit with a controller.;CONSTITUTION: A doctoring device for a gravure printer includes a doctor unit (100), a deformation unit (200), an advance-and-retreat unit (300), a lifting unit (400), and a controller. The doctor unit is arranged along the longitudinal direction of a printing cylinder (10) and includes blades removing ink remaining on a non-drawing portion of the printing cylinder. The deformation unit includes a first driving unit (210) and adjusts the angle of the doctor unit. The advance-and-retreat unit includes a second driving unit (310) and advances and retreats the doctor unit. The lifting unit includes a third driving unit (410) and lifts the doctor unit upwardly and downwardly. The controller stores a preset doctoring position value of the doctor unit according to printing conditions and operates the driving units depending on the stored position value, thereby controlling the position of the doctor unit.;COPYRIGHT KIPO 2013
