Embodiment 1
[0037] The method for ejecting ink from a black and white printer includes the following steps:
[0038] S1: start the booster pump 21, a negative pressure is formed in the return pipe 40, causing the residual ink in the ink outlet pipe 12 to flow;
[0039] S2: The pressure limiting valve is opened, the air will enter the booster pump 21 from the pressure limiting valve, then the air will enter the booster pipe 20 after passing through the booster pump 21, and finally enter the intake pipe 14;
[0040] S3: Air enters the box in the form of air bubbles from the lower end of the intake pipe 14, and the impeller 30 rotates by using the buoyancy of the bubbles, and then drives the stirring plate to vibrate, so that the ink in the box is stirred and mixed, and the pressure in the box increases. When the trigger pressure of the pressure relief valve 11 is reached, the pressure relief valve 11 is opened, and the air is discharged from the pressure relief valve 11 of the air outlet; ...

The invention belongs to the field of printing equipment, and provides an ink outlet method of a black-and-white printer, which aims to solve the technical problems of insufficiency in mixing and easiness in precipitation of ink of an existing ink outlet method of the black-and-white printer. The ink outlet method comprises the following steps of (S1) starting a booster pump so as to form negativepressure in a backflow pipeline and enable residual ink in an ink outlet pipe to flow; (S2) opening a pressure limiting valve, so that air enters the booster pump from the pressure limiting valve, then enters a booster pipe by virtue of the booster pump and enters an air inlet pipe at last; (S3) enabling the air to enter a box body in the form of bubbles from the lower end of the air inlet pipe,so that an impeller is rotated by utilizing the buoyancy of water bubbles, then a mixing plate is driven to vibrate, ink in the box body is stirred and mixed, the intensity of pressure in the box bodyis increased, a pressure relief valve is opened when reaching the trigger pressure of the pressure relief valve, and the air is discharged from the pressure relief valve of an air outlet; and (S4) opening an electromagnetic valve at an ink outlet, so that ink enters the ink outlet pipe from the ink outlet and enters an inkjet head at last.
Description
technical field [0001] The invention relates to the field of printing equipment, in particular to an ink output method for a black and white printer. Background technique [0002] In order to save costs, most of the existing black and white printers used split ink cartridges. In practical applications, the split ink cartridge is usually directly connected to the nozzle of the printer, so that the ink in the ink cartridge can directly enter the nozzle to complete printing. [0003] Specifically, in order to protect the nozzle of the printer, fillers of porous media such as sponge or other pressure regulating devices are usually installed in the ink cartridge to ensure that the ink cartridge is in a constant pressure state, so that the ink in the ink cartridge can enter the nozzle at a uniform speed. However, the use of the filling body will occupy the space in the ink cartridge, resulting in a decrease in the volume of the ink contained in the ink cartridge. Therefore, most ...
