Abstract

This utility model discloses a doctor blade device for a gravure printing machine, including a frame, a gravure roller, an ink tank, a telescopic cylinder, and a horizontal adjustment frame. The gravure roller is pivotally mounted on the frame and connected to a rotary motor. The lower part of the gravure roller is immersed in the ink tank and can be driven by the rotary motor to penetrate the wall of the gravure roller, and rotates clockwise. The frame is provided with a base, and a vertical seat is vertically slidably mounted on the upper wall of the base. The base is provided with a vertical drive device for driving the vertical seat to move vertically. At least two telescopic cylinders are provided, and the lower part of the telescopic cylinder is pivotally mounted on the vertical seat. The drive end of the telescopic cylinder is pivotally connected to an inclined adjustment seat, and the lower end of the inclined adjustment seat is pivotally mounted on the frame. The horizontal adjustment frame is mounted on the inclined adjustment seat and is used to drive the doctor blade to move between a position close to the gravure roller and a position far away from the gravure roller. The doctor blade is located at the upper part of the rear position of the gravure roller.
