Problems solved by technology

[0003] At present, in the engraving process of the engraving roller, it is necessary to stuff pearl cotton or a belt into the engraving roller to achieve the shock absorption effect during the engraving process, and to prevent the engraving process of the engraving roller from causing damage to the engraving roller. and other problems, and stuffing pearl cotton or belts is not only time-consuming, but also causes environmental pollution in the workshop; moreover, the gravure roller itself does not have a shock-absorbing effect

Abstract

The invention discloses a damping device for a gravure plate roller on a laser engraving machine, which belongs to the technical field of laser engraving, and solves the problem that a gravure plate roller on the laser engraving machine lacks damping performance. The technical key points are as follows: the damping device comprises a plate roller rack and the gravure plate roller, wherein the gravure plate roller is mounted in a plate roller groove in the plate roller rack and comprises a roller barrel, protruding blocks and grooves are arranged on the inner surface of the roller barrel, and adamping bag is installed in the roller barrel; annular sealing plates are connected to two ends of the roller barrel, and roller shafts are welded to the middles of the annular sealing plates; and the roller shafts are installed in sliders, the upper ends of sliding chutes are connected with guide rods, and damping springs sleeves the parts, above the sliders, of the guide rods. By arranging thegravure protruding blocks and the through grooves on the roller barrel of the gravure plate roller, the damping bag is used for extruding a damping pad to be located in the grooves, and then the damping for a material during the gravure process is realized; and meanwhile, the sliders on the roller shafts are damped under the elastic force of the damping springs, and thus a good damping effect is achieved.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to a shock absorbing device for gravure plate rollers on a laser engraving machine. Background technique [0002] The biggest difference between laser engraving and traditional engraving equipment and manual engraving is the wide range of engraving resolution and high precision. During the engraving process, gravure plate rollers continue to expand their market share due to their high color saturation and large printing capacity. In traditional gravure plate making, gravure plate making such as electric engraving, manual etching, and laser etching There are limitations in both process and printing functions. [0003] At present, in the engraving process of the engraving roller, it is necessary to stuff pearl cotton or belts into the engraving roller to achieve the shock absorption effect during the engraving process, and to prevent the engraving process of the engraving rol...
