A digital inkjet printing device of a traditional flat screen printing machine

Abstract

The invention discloses a digital inkjet printing device of a traditional flat screen printing machine. The servo motor of the nozzle rotates to drive the connecting rod, connecting rod gear, chain, and secondary gear to rotate, and finally drives the scanning integrated transfer vehicle to go back and forth in the direction of the width of the gray fabric. Mobile, two pairs of position sensors in the raster reading head collect the precise displacement signal of the scanning integrated transfer vehicle and send it to the controller. The controller sends the inkjet printing information to the nozzle board through the cable to control the work of the multi-nozzle group. The positive pressure air source in the ink circuit system sends the various inks in the first-level ink cartridge to the second-level ink cartridge. The ink of each color is sprayed onto the gray fabric through the multiple nozzle groups controlled by the nozzle board. The servo motor of the guide belt accurately controls the movement of the printing guide belt. Finally, , driving the gray cloth to move. The invention is also provided with an ink stack moisturizing device and a scraper blade to maintain the nozzle. The invention has the beneficial effects of reasonable structure, transforming traditional printing machines, improving printing quality, and being green and environmentally friendly.

Description

technical field [0001] The invention relates to a digital inkjet printing device of a traditional flat screen printing machine. Background technique [0002] In the prior art, the screen printing scraper of the traditional flat screen has not been replaced by a digital printing nozzle group so far, and fast scanning and inkjet are performed according to the pattern of the traditional printing. Traditional screen printing is a traditional technique in which the motor drives the scraper on the squeegee to squeegee printing on the screen, and the slurry is infiltrated into the gray fabric through pressure, resulting in a lot of waste of printing slurry. The printing technology is to make a screen through a screen, and go through multiple complex processes such as plate making, exposure, screen drying, screen pulling, screen sweeping alignment, and color matching. sewage discharge problem. Contents of the invention [0003] Based on the above deficiencies, the present invent...
