Abstract

The invention discloses a doctor blade device of a photogravure press. The doctor blade device comprises a doctor blade angle adjusting device, a doctor blade lifting device is arranged on one side of the doctor blade angle adjusting device and connected with a doctor blade shifting device, and a doctor blade clamping plate device is arranged above the doctor blade angle adjusting device. The problems that an existing doctor blade device is complex in structure and high in noise during low-speed printing are solved.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and relates to a scraper device of a gravure printing machine. Background technique [0002] In the printing process of the gravure printing machine, the scraper is an important part of the gravure printing machine. Its function is mainly to scrape off the excess ink on the surface of the inked plate roller, so that a certain amount of ink is retained in the plate roll cell. The remaining ink is transferred to the printing film under the printing pressure, so that the pattern can be reproduced. The scraper device of the existing gravure printing machine has a complex and bulky structure; the overall rigidity and stability are poor; the noise is loud when printing at a low speed below 15 m / min; the stability is poor at high speed printing, and the pattern will appear wavy deformation when printing at a speed above 300 m / min , affecting the overall printing effect; when printing at a hi...
