Continuous ink supplying device for ink-jet printer

The invention relates to the technical field of ink supplying systems, and discloses a continuous ink supplying device for an ink-jet printer. The continuous ink supplying device for the ink-jet printer comprises a fixing disc, and an ink supplying box is connected to the left side of the upper surface of the fixing disc through a control device in a movable sleeving and fixed mode. According to the continuous ink supplying device for the ink-jet printer, through a threaded connection mode of a clamping control device and an adjusting sleeve bolt, the position of the ink supplying box at the control device is convenient to adjust, and the phenomenon that due to the fact that the positions of opposite nozzles of the ink supplying box are too high and are about 50 millimeters, ink in an inkconveying pipeline flows automatically under the gravity action is avoided; and if the automatic flowing phenomenon of the ink still occurs when the ink supplying box and the nozzles are located on asame horizontal plane, a p
