Problems solved by technology

[0003]The adhesion between the raised part of the flexographic plate and the surface of the substrate plays a vital role in the overall printing effect, that is, the raised part of the flexographic plate is in contact with the substrate. When the surface of the object is touched, or because of the unevenness of the contact position, and after printing, smudged or poor dyeing strength occurs, resulting in blurred printing. Based on this phenomenon, a new type of flexible printing equipment is urgently needed to solve the current problems. troubles

Abstract

The invention provides a flexible printing device and a printing method thereof, which relate to the field of flexographic printing and include a printing press cylinder and a self-adjusting printing plate mechanism. The plate mechanism includes moving components, rollers, pressure detection tubes, sliders, pneumatic units, L-shaped support rods and sleeves. There is a roller on the rolling side of the impression roller, and a flexographic plate is attached to the surface of the roller. The flexographic plate and the impression roller It is in rolling contact shape; the rolling surface of the roller is evenly provided with holes, and the moving component is inserted horizontally in the roller, and the two ends of the moving component are inserted into the bearings set on the end surface of the roller; a pressure detection tube is arranged above the roller, and the inner sleeve of the pressure detection tube is Connected with a sleeve, the two sides of the sleeve are equipped with pneumatic units, which are positioned after detection, and the flexographic plate is repaired after positioning, thereby avoiding the problem of poor printing quality caused by local defects during the use of the flexographic plate.

Description

technical field [0001] The invention relates to the field of flexographic printing, in particular to a flexographic printing device and a printing method thereof. Background technique [0002] Flexographic printing is printing by using a flexible printing plate and transferring ink through an anilox roller. It is a kind of letterpress printing process, referred to as flexo printing. The graphic part of the flexographic printing plate is raised, and the anilox roller evenly coats a certain thickness of ink layer on the graphic part of the printing plate during printing, and then under the action of the pressure of the embossing roller, the ink layer of the graphic part Transfer to the surface of the substrate to form clear graphics. [0003] The degree of fit between the protrusions of the flexographic plate and the surface of the substrate plays a vital role in the overall printing effect, that is, when the protrusions of the flexographic plate contact the surface of the su...
