Description

Device for preventing ink deposition

Technical Field

The utility model relates to an inkjet printing equipment technical field especially relates to a prevent ink deposition device.

Background

Inkjet printers are a common type of printing device. An inkjet printer generally includes a printer body and a carriage unit that is slidably disposed on a carriage rail of the printer body in a reciprocating manner. The carriage device is provided with a printing head, and in order to keep the ink ejection process from a nozzle of the printing head in an optimal condition, the ink jet printer ejects ink at a designated position by the nozzle before or during printing, so that the nozzle is maintained and prevented from being blocked. Or the printer does not print for a long time, the spray head has deposition, and the deposited ink can be sprayed in the spraying process, so that the printing image quality is improved.

Due to the requirement of printing density, the ink generally includes pigment ink and dye ink, for example, the black ink is pigment ink, and the color ink is dye ink. The pigment ink is a dispersion composed of particles, and the dye ink is water-soluble ink. When the pigment ink is sprayed on the waste ink cotton, the pigment ink has large solid particles, and is deposited when the moisture of the pigment ink evaporates. When the pigment ink is deposited to a high level, it comes into contact with the head to contaminate the head or clog the head, thereby deteriorating the image quality. In order to avoid the contamination or blockage of the nozzle, the user often needs to regularly check whether the ink deposits exist, and the accumulated ink deposits are cleaned in a mechanical floating mode, which is relatively complicated, and the user easily forgets to check the ink deposits, so that the ink head is contaminated.
