The internal circulation method requires precise control of the ink flow rate. When the flow rate is unstable or inappropriate, it will affect the shape of the ink in the nozzle, thereby affecting the printing.
The internal circulation ink supply system on the market is only suitable for nozzles with internal circulation function. The ink is always in a circulating state, which requires high precision and control of the accessories in the system, and the ink flow rate and flow control are very strict. Disturb the ink inside the nozz

The invention discloses an ink supply system and an ink supply method of a printer. The ink supply system comprises an ink box, a nozzle, an ink supply path, an ink return path, a circulating pump and a control device. The ink box is used for supplying ink to the printer. The nozzle is used for ink-jet printing. The ink box communicates with the nozzle through the ink supply path, and ink is conveyed to the nozzle from the ink box. The nozzle communicates with the ink box through the ink return path, and ink is conveyed to the ink box from the nozzle. The circulating pump is arranged on the ink return path and is used for pumping the ink out of the nozzle. The control device is used for controlling the conduction of the ink supply path and the ink return path and the starting and closing of the circulating pump. The ink box comprises a main ink box body and a secondary ink box body, wherein the secondary ink box body is arranged on the ink supply path and located between the nozzle and the main ink box body. When the amount of the ink in the secondary ink box is sufficient, the control device starts the circulating pump, and the ink is pumped back to the main ink box from the nozzle through the circulating pump. Ink in the secondary ink box automatically flows into the nozzle. By means of the mode, circulation of the printing ink in the nozzle is achieved, and the applicability to the nozzle is higher.
Description
technical field [0001] The present application relates to the technical field of printers, in particular to an ink supply system and an ink supply method of a printer. Background technique [0002] The ink supply system of an inkjet printer is one of the core components of an inkjet printer. It provides continuous and stable ink to the nozzle, guarantees the ejection quality of the ink droplets of the nozzle, and also provides support for extending the service life of the nozzle. [0003] At present, the ink supply systems of inkjet printers on the market mainly include internal circulation and external circulation. The internal circulation method requires precise control of the ink flow rate. When the flow rate is unstable or inappropriate, it will affect the shape of the ink in the nozzle, thereby affecting printing. The internal circulation ink supply system on the market is only suitable for nozzles with internal circulation function. The ink is always in a circulating ...
