The embodiment of the application provides an ink supply method, which can be used for supplying ink to an ink jet printing head 6 of an ink jet printer, as shown in fig. 1 and fig. 2, the ink circulates in a circulation loop 1, and the circulation loop 1 is provided with an ink box 2, a circulation pump 3, a heater 4, a first sensor assembly 5, the ink jet printing head 6 and a second sensor assembly 7 in sequence along the circulation flow direction of the ink; or it can be understood that the ink cartridge 2, the circulation pump 3, the heater 4, the first sensor unit 5, the ink jet print head 6 and the second sensor unit 7 are connected end to end in sequence and form a loop in which the ink circulates, sequentially circulating through the ink cartridge 2, the circulation pump 3, the heater 4, the first sensor unit 5, the ink jet print head 6, the second sensor unit 7, the ink cartridge 2 …
The method comprises the following steps:
the first sensor assembly 5 acquires first temperature information and first negative pressure information of the ink and transmits the first temperature information and the first negative pressure information to the controller 8, and the second sensor assembly 7 acquires second temperature information and second negative pressure information of the ink and transmits the second temperature information and the second negative pressure information to the controller 8. Specifically, the first sensor assembly 5 acquires first temperature information and first negative pressure information when the ink flows through the first sensor assembly 5, and the second sensor assembly 7 acquires second temperature information and second negative pressure information when the ink flows through the second sensor assembly 7. In particular, the controller 8 may be a programmable logic controller 8, i.e. a PLC.
The controller 8 calculates a first difference value between the first temperature information and the second temperature information, compares the first difference value with a first preset value, and if the first difference value is greater than the first preset value, the controller 8 controls the heater 4 to reduce power so as to reduce the heating power of the heater 4 to the ink, so that the first difference value is reduced and approaches to the first preset value; if the first difference is smaller than the first preset value, the controller 8 controls the heater 4 to increase the power to heat the ink by the heater 4, so that the first difference increases and approaches the first preset value.
The controller 8 calculates a second difference value between the first negative pressure information and the second negative pressure information, compares the second difference value with a second preset value, and if the second difference value is greater than the second preset value, the controller 8 controls the circulating pump 3 to reduce the power so as to reduce the suction power of the circulating pump 3 to the ink and enable the second difference value to be reduced and approach to the second preset value; if the second difference is smaller than the second preset value, the controller 8 controls the circulation pump 3 to increase the power to increase the suction power of the circulation pump 3 to the ink, so that the second difference increases and approaches the second preset value.
The ink in the ink box 2 forms a certain negative pressure through the suction of the circulating pump 3, then enters the heater 4 to be heated and heated, and flows through the first sensor assembly 5, and the first sensor assembly 5 acquires first temperature information and first negative pressure information of the flowing ink and transmits the first temperature information and the first negative pressure information to the controller 8. Then the ink flows into the ink jet print head 6, part of the ink is ejected by the ink jet print head 6 for printing, and the excess ink flows out of the ink jet print head 6 and flows through the second sensor component 7; since a portion of the ink is ejected by the inkjet printhead 6, a portion of the heat and pressure is lost, and thus the temperature and negative pressure at which the ink flows out of the inkjet printhead 6 are lower than the temperature and negative pressure at which the ink flows into the inkjet printhead 6, respectively. The second sensor assembly 7 acquires second temperature information and second negative pressure information of the ink flowing through and transmits the second temperature information and the second negative pressure information to the controller 8, and the ink flowing through the second sensor assembly 7 flows back into the ink cartridge 2 again, so that the ink continuously circulates in the circulation circuit 1 in which the ink cartridge 2, the circulation pump 3, the heater 4, the first sensor assembly 5, the inkjet printing head 6 and the second sensor are sequentially arranged.
The embodiment of the application acquires the first temperature information and the first negative pressure information of the ink before the ink flows into the ink jet printing head 6 through the first sensor assembly 5, second temperature information and second negative pressure information of the ink are acquired by the second sensor assembly 7 after the ink has flowed out of the inkjet printhead 6, the difference in the temperature of the ink flowing into the ink jet print head 6 and the temperature of the ink flowing out of the ink jet print head 6 (i.e. the first difference) and the difference in the negative pressure of the ink flowing into the ink jet print head 6 and the ink flowing out of the ink jet print head 6 (i.e. the second difference) can be calculated by the controller 8, the controller 8 then compares the first difference with a first preset value and the second difference with a second preset value, so that the controller 8 can control the heater 4 to reduce or increase the power according to the condition of the first difference and control the circulating pump 3 to reduce or increase the power according to the condition of the second difference. The method can reduce the temperature fluctuation and the negative pressure fluctuation between the ink inflow end and the ink outflow end of the ink-jet printing head 6 as much as possible, and ensure that the temperature difference and the negative pressure difference between the ink inflow end and the ink outflow end of the ink-jet printing head 6 tend to be stable respectively, thereby ensuring that the ink-jet temperature and the ink-jet pressure of the ink-jet printing head 6 keep stable, further improving the printing quality of the ink-jet printing head 6, and reducing the ink break, the wire pull and other situations of the ink-jet printing head 6.

Generally, the ink cartridge 2 stores only a small amount of ink therein to ensure a stable pressure in the circulation circuit 1. The ink box 2 is connected with an ink supply barrel 11 through an ink supply branch 10 with an ink supply pump 12, and when the liquid level in the ink box 2 is lower than a preset liquid level, the ink supply pump 12 pumps and supplements the ink stored in the ink supply barrel 11 into the ink box 2 through a float switch 9 and a controller 8; when the liquid level in the ink cartridge 2 becomes higher than the predetermined liquid level, the float switch 9 and the controller 8 stop the operation of the ink supply pump 12. This method enables the ink cartridge 2 to be automatically replenished with ink in a timely manner, and enables the ink jet head 6 to operate stably for a long period of time.

The flow rate of the ink flowing through the ink jet printing head 6 can be adjusted by adjusting the flow rate of the ink of the flow rate adjusting branch 13 through the flow rate adjusting device 14, so that the ink jet amount of the ink jet printing head 6 is controlled; for example, if the flow rate of the ink flowing through the flow rate adjusting branch 13 is increased, the flow rate of the ink flowing through the ink jet print head 6 is decreased, whereas if the flow rate of the ink flowing through the flow rate adjusting branch 13 is decreased, the flow rate of the ink flowing through the ink jet print head 6 is increased.
