Abstract

The invention discloses an inkjet printing device with a distance measuring function. The device comprises a spray head and a control module, wherein the spray head comprises a spray nozzle, a pair of charging pole plates used for charging ink drops, a pair of high-voltage pole plates used for deflecting the charged ink drops, as well as a distance measuring device which is fixed relative to the spray head; and the control module comprises an ink route system, an ink drop charging control system, a high-voltage control system, a controller and a storage device where at least one table group is stored. According to the device provided by the invention, different charging methods and charging compensation data are utilized according to different inkjet printing distances, so as to achieve a good inkjet printing effect. The invention further discloses an inkjet printing method with the distance measuring function.

Description

Technical field [0001] The invention relates to the technical field of code spraying, in particular to a code spraying device and method with a distance measuring function. Background technique [0002] Continuous inkjet technology is a technology that uses the nozzle part to continuously eject evenly spaced ink droplets to the substrate to complete the jet printing. According to the printing content and the requirements of the printing effect, the charging plate selectively charges the ink droplets in the ejection process with different amounts of electricity, so that the flying trajectory of the charged ink droplets when passing through the electric field formed by the high voltage plate is generated. Different degrees of deviation, so as to form different patterns on the substrate. The factors that affect the quality of printing usually include ink characteristics, ink drop flying speed and printing distance. Because the distance between the nozzle of the traditional printer...
