Example one
The embodiment of the present invention provides an ink supply method, which is applied to an ink path negative pressure control system, wherein the system includes an ink supply pump, the ink supply pump is used for transferring ink in an ink barrel into an ink cartridge, the ink supply pump, the ink barrel and the ink cartridge may be the ink supply pump 6, the ink barrel 7 and the ink cartridge 3 shown in the above application scenarios and fig. 1 and 2, and specifically may be set according to actual needs, please refer to fig. 3, which shows a flow of the ink supply method provided by the embodiment of the present invention, and the method includes, but is not limited to, the following steps:
step S10: acquiring printing data of a current image to be printed;
in the embodiment of the invention, the printing control module acquires printing data in real time, wherein the printing data comprises data of ink jetting area, ink jetting times at the same position, ink jetting size, ink jetting position and the like of a printing image, and the printing control module can acquire a printing task input by a user or automatically acquire an image to be printed according to a preset printing task, and further determine the printing data from the image to be printed so as to calculate the ink amount required for printing the printing image.
Step S20: determining the predicted ink consumption of the digital spray head to execute the current ink-jet printing work according to the printing data;
in the embodiment of the present invention, in order to supplement the ink in the ink cartridge in real time and achieve how much ink is supplemented in time when how much ink is consumed, it is necessary to calculate the predicted ink consumption amount when the inkjet printing operation is performed each time. Specifically, the determining the predicted ink consumption of the digital nozzle to execute the current inkjet printing work according to the printing data includes: determining the ink jetting amount required to be consumed by each nozzle on the digital nozzle during ink jetting each time when the current ink jetting work is executed; and accumulating the ink jetting amount required to be consumed by all the nozzles during each printing to obtain the predicted ink consumption amount.
Step S30: and controlling the ink supply pump to supplement the ink for the ink box according to the predicted ink consumption.
In an embodiment of the present invention, the controlling the ink supply pump to replenish the ink cartridge with ink according to the predicted ink consumption includes: and according to the calculated predicted ink consumption, replenishing ink to the ink box in real time according to a preset speed. Specifically, the printing control module sends the predicted ink consumption to the ink supply pump, and the ink supply pump supplements the ink in real time in the printing process according to the numerical value of the predicted ink consumption, so that the supplement of the ink is smooth and stable, and the dynamic balance of the ink in the ink box is ensured. During the ink replenishing process, the ink replenishing speed can be controlled, the ink can be slowly replenished so as to further reduce the fluctuation of the ink liquid level in the ink box, for example, the predicted ink consumption can be divided by the required time between the current ink-jet printing and the next ink-jet printing to obtain the replenishing speed, and the ink supplying pump is controlled to supply ink according to the replenishing speed, so that the ink in the ink box can be timely replenished during the next ink-jet printing, the ink can be replenished to the ink box at a stable speed, and the fluctuation of the liquid level is reduced.
In some embodiments, the ink path negative pressure control system further includes a vacuum generator, a negative pressure stabilizing device, and a negative pressure number detecting device, the negative pressure stabilizing device is respectively connected to the vacuum generator and the negative pressure number detecting device, the vacuum generator and the negative pressure stabilizing device may be the vacuum generator 1 and the negative pressure stabilizing device 2 shown in the above application scenarios and fig. 1 and fig. 2, please refer to fig. 4, which shows a flow of another ink supply method provided by an embodiment of the present invention, and the method may be specifically set according to actual needs, and further includes:
step S41: detecting a negative pressure value in the ink cartridge by the negative pressure number detection device;
step S42: judging whether the negative pressure value in the ink box is within a preset range of a set negative pressure value or not; if not, jumping to step S43;
step S43: and adjusting the negative pressure in the ink box through the vacuum generator so as to adjust the negative pressure in the ink box to the set negative pressure value.
Specifically, on the premise that the ink supply pump supplies ink to the ink box in real time, a negative pressure stabilizing device and a negative pressure number detection device can be further arranged to monitor the negative pressure value in the ink box in real time, and judge the change situation of the negative pressure value in the ink box, if the negative pressure value in the ink box changes and changes greatly and exceeds a normal fluctuation range, namely the preset range of the set negative pressure value, the negative pressure value in the ink box needs to be adjusted to the set negative pressure value quickly, timely and automatically through the vacuum generator, and the stability of the negative pressure in the ink box is determined.
In some embodiments, the ink path negative pressure control system further includes a liquid level sensor, where the liquid level sensor may be the liquid level sensor 4 shown in fig. 1 and fig. 2, please refer to fig. 5, which shows a flow of another ink supply method provided in an embodiment of the present invention, and the flow may be specifically set according to actual needs, where the method further includes:
step S51: detecting an actual amount of ink within the ink cartridge by the level sensor;
step S52: judging whether the actual ink quantity is lower than an ink lower limit value of the ink box or higher than an ink upper limit value of the ink box;
step S53: if the actual ink quantity is lower than the lower ink limit value of the ink box, calculating the ink supply quantity required to be increased by the ink supply pump according to the ink adding times and the ink adding quantity from the actual ink quantity to the lower ink limit value;
step S54: and if the actual ink quantity is higher than the upper ink limit value of the ink box, calculating the ink supply quantity required to be reduced by the ink supply pump according to the ink adding times and the ink adding quantity from the actual ink quantity to the upper ink limit value of the ink box.
Furthermore, because the nozzles of the digital nozzles cannot be completely consistent due to processing, a small difference exists between the amount of ink ejected by each nozzle and a theoretical situation, and further, the difference exists between the amount of ink actually ejected by each digital nozzle and the theoretically predicted amount of ink consumption calculated by the print control module according to the print data, and an error is accumulated along with the increase of the number of times of ink ejection, so that the ink in the ink cartridge is too much or too little, therefore, a liquid level sensor can be installed in the ink cartridge to provide limit protection, the amount of ink supplied by the subsequent ink supply pump each time is reduced when the actual amount of ink in the ink cartridge reaches the upper limit value of the liquid level sensor, and the amount of ink supplied by the subsequent ink supply pump each time is increased when the actual amount of ink in the ink cartridge reaches the lower limit value of the liquid level sensor, the actual ejection consumption of each nozzle is increased or decreased according to the ink adding times from the actual ink amount to the upper limit value or the lower limit value and the ink adding amount of each time, and the ink supply amount of each time of the subsequent ink supply pump is corrected in time according to the increased amount and the decreased amount.
In some embodiments, with continuing reference to fig. 5, when the actual amount of ink is below the lower ink limit value of the ink cartridge or the actual amount of ink is above the upper ink limit value of the ink cartridge, the method further comprises:
step S55: and outputting the warning information.
