High-speed digital inkjet printer

Abstract

The utility model relates to a high-speed digital inkjet printing device employing print heads and used for various kinds of printing operation. The high-speed digital inkjet printing device comprises a color bar, a suctioning unit, a wiping unit, a capping unit, and a memory buffer. The color bar includes a plurality of piezo inkjet print heads and nozzle capable of printing according to the width of a target printed matter, expresses a plurality of colors on the target printed matter, and performs shaking to left and right sides in printing. The suctioning and wiping devices include a cleaning solution spray capable of wiping foreign materials stuck to the nozzle of the color bar and ink. The capping device collects the ink fallen in the maintenance of the color bar and closes the plurality of piezo inkjet print heads installed in the color bar to prevent the nozzle from being blocked when the printing operation is stopped for a long time. The memory buffer stably transmits image data corresponding to the shaking.

Description

technical field [0001] The present invention relates to a high-speed digital inkjet printing device using nozzles for various printing operations, and particularly relates to integrating the advantages of the nozzle moving (shaking) method and the nozzle fixing (single pass) method and making up for the disadvantages, so that not only high-speed printing can be performed, Moreover, it is a hybrid high-speed digital inkjet printing device that can significantly reduce nozzle clogging. Background technique [0002] Recently, in the process of packaging printing and clothing printing and dyeing, including paper printing, instead of screen printing machines or roll printing machines that must go through the process of drawing and plate making and have complicated processes, a machine that can directly use computer editing through digital printing has been developed. The image or redesigned image of the image data input by the camera or scanner is printed on the printing object t...

AI Technical Summary

Problems solved by technology

[0006] In the case of the nozzle fixing method in the prior art, if the nozzle clogging occurs, the nozzles at the same position cannot be ejected normally, and there will be a section that cannot be printed, that is, a defective product

[0007] In addition, because not all nozzles have the same performance, the spray quality is not uniform, and the problem of different colors is likely to occur

[0008] In addition, the digital inkjet printing device in the prior art cannot prevent the phenomenon of nozzle drying and clogging when the printing is suspended
