Ink-jet printer and printing method thereof

Abstract

The invention discloses an ink-jet printer and a printing method thereof. The ink-jet printer comprises a printing module, supporting beams, a printing platform, an ink-scraping maintenance device and a control system. The printing module is installed above the supporting beams, a sprayer is installed at the lower end of the printing module, and the printing platform is arranged below one ends of the supporting beams. The ink-scraping maintenance device is arranged below the other ends of the supporting beams, the control system is used for controlling work of the printing module, the ink-scraping maintenance device and the sprayer. The ink-jet printer is characterized in that the ink-scraping maintenance device comprises a lifting device, and the lifting device can make lifting movement on the whole in the vertical direction, namely in the Z-axis direction; by controlling overall lifting of the ink-scraping maintenance device and horizontal movement of the printing module in the direction of the supporting beams, ink-scraping or maintenance operation of the sprayer is completed, the lifting device is skillful in structure design, and lifting smoothness and steadiness are high; and in the ink-scraping maintenance process, by approaching a sensor for automatic detection and controlling the distance between the sprayer and the ink-scraping maintenance device, accuracy can be improved, and quick and convenient ink-scraping maintenance is achieved.

Description

technical field [0001] The invention relates to an ink-jet printer and a printing method thereof, in particular to an ink-jet printer and a printing method of a one-time fast-pass printing medium installed with an ink scraping maintenance device. Background technique [0002] At present, during the working process of industrial inkjet printers, the nozzles of the printer spray ink droplets to form graphics on the printing medium. After printing for a period of time, ink or dust is likely to remain on the nozzle holes of the nozzles, which may easily cause blockage of the nozzle holes of the nozzles and ink breakage. In this case, it is necessary to press ink on the nozzle and wipe it to clear the nozzle hole. During the process of pressing ink and wiping the nozzle, the ink splashed out of the nozzle hole needs to be collected in a container and discharged in time. The falling waste ink cannot be effectively discharged, which will not only affect the appearance but also easi...

Problems solved by technology

[0005] In the scraping process, many devices only design one scraper to scrape ink sequentially for the entire row of nozzles. The scraping process takes a long time. In a design with a large number of nozzles and a long overall size, if the conventional method That is to say, the design of one scraper to scrape ink on the entire row of nozzles will prolong the scraping process and reduce work efficiency. Now it is necessary to design a design method that speeds up the overall scraping ink and wipes ink on each nozzle synchronously to improve the efficiency. Work efficiency and precision
