Vibration-adsorption structure of carving knife of digital wide-width electronic carving machine

Abstract

The invention discloses a vibration-adsorption structure of a carving knife of a digital wide-width electronic carving machine. Magneto-rheological fluid and magnet exciting coils are arranged on the two sides of a cantilever which is connected with the carving knife through flanges respectively and are connected with a controller through leads; the magneto-rheological fluid is filled into a cavity through a through hole and is sealed by a magnet-shielding sleeve and a seal ring; the magnet-shielding sleeve is connected with a supporting sleeve through an anti-vibration pad; the supporting sleeve for supporting the cantilever is fixedly connected with a machine tool through a flange structure; the cantilever is connected with the supporting sleeve by a sliding pair; and the rotating degree of freedom of the cantilever is limited by a set screw. The vibration-adsorption structure has the advantages of simpleness and easy processing production and reduces the vibration through the damping change of the magneto-rheological fluid and is particularly suitable for a system which needs axial vibration adsorption so as to control the magnitude of the vibration and improve processing precision.

Description

technical field [0001] The invention relates to electronic engraving technology, in particular to a vibration-damping structure of an engraving knife of a digital wide-width electronic engraving machine. Background technique [0002] As one of the four major printing methods, gravure printing has the characteristics of vivid images, fine layers, bright colors and is suitable for printing applications of high-end products. In particular, its plate-making process has developed rapidly from corrosion plate-making to electronic engraving plate-making. With its obvious advantages of simplicity, efficiency, reliability and greenness, this method has been increasingly valued by the industry and has been more widely used. It has played a role in the printing industry. increasingly important role. Therefore, it is of great practical significance to study new technologies and processes of gravure printing, and to develop related gravure printing processing equipment and equipment. T...

Problems solved by technology

Because the damping coefficient of the traditional shock absorber is difficult to adjust at high frequency, it cannot be applied to the vibration reduction of the main shaft of the electronic engraving plate-setting machine with high-speed vibration
