The invention provides an ink loading device for a
digital printing. The ink loading device comprises a
machine body and ink boxes, a control panel is arranged on the front side of the
machine body, and a controller is arranged in the control panel; liquid inlet pipes and liquid outlet pipes are connected to the ink box, liquid level sensors are arranged in the ink boxes, and the liquid level sensors are connected to the controller, the liquid inlet pipes are provided with liquid extractors, a liquid inlet circuit is arranged in the controller, and the liquid extractors are connected to the liquid inlet circuit; color discriminators are arranged on the liquid inlet pipes, the color discriminators are connected to the controller, an ink
pipe inserting row is connected to the port of the liquid outlet pipes, middle pipes are arranged in the ink
pipe inserting row, electromagnetic valves are arranged in the middle pipes, the two ends of the middle
pipe are provided with first connectors and second connectors, the first connectors are connected with the liquid outlet pipes, the second connectors are connected with the digital printer, and the electromagnetic valves are controlled by the controller. According to the ink loading device for the
digital printing, the liquid extractors and the color discriminators are added additional, and the liquid extractor is used for adding ink into the ink box in an automatic manner, so that the situation that the ink is used up is avoided; and the color
discriminator is used for automatically identifying the color of the added ink, ink of different colors is prevented from being doped with each other.
