Digital inkjet printing device of conventional flat screen printing machine

Abstract

The invention discloses a digital inkjet printing device of a conventional flat screen printing machine. A spray head servo motor rotates to drive a connecting rod, a connecting rod gear, a chain and a pinion to rotate, and finally drives a scanning type integrated transferring trolley to move to and fro along the width direction of greige cloth; two pairs of position sensors in an optical grating read head collect the accurate displacement signals of the scanning type integrated transferring trolley, and sends the accurate displacement signals of the scanning type integrated transferring trolley to a controller; the controller sends inkjet printing information to a spray head board card through a cable wire to control a multi-spray-head group to work; a positive-pressure air supply in an ink line system delivers various colors of ink in a primary ink box to a secondary ink box; the various colors of ink is sprayed on the greige cloth through the multi-spray-head group controlled by the spray head board card; and a guide belt servo motor accurately controls a printing guide belt to move, and finally drives the greige cloth to move. The digital inkjet printing device of the conventional flat screen printing machine is also provided with an ink stack moisture preserving device and ink scraping knife leathers, so as to maintain spray heads. The digital inkjet printing device of the conventional flat screen printing machine has the beneficial effects of being reasonable in structure, modifying a conventional printing machine, improving printing quality and being green and environment-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 Background technique [0002] In the prior art, the screen printing scraper of the traditional flat screen has not been replaced by a digital printing nozzle group so far, and fast scanning and inkjet are performed according to the pattern of the traditional printing.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 complicated 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 presen...
