Embodiment one

An embodiment of the present invention provides an inkjet printer ink pressure control method, the method is suitable for inkjet printers with a standby flash printing function, including flatbed inkjet printers, UV inkjet printers, digital textile inkjet printers and the like. Referring to Figure 1, the method includes the following steps:

S1: When the ink-pressing signal is obtained in the standby state, it is judged whether the inkjet printer is performing a flash cleaning operation, wherein the ink-pressing signal is used to drive the ink-jet printer ink supply system to start the ink-pressing operation;

S2: If the inkjet printer is performing a flash cleaning operation, then stop the flash cleaning operation and turn off the standby flash function, and then perform an ink pressing operation;

S3: judging whether a new ink pressing signal is obtained;

S4: If a new ink-pressing signal is obtained, the ink-pressing operation is performed again until no new ink-pressing signal is obtained;

S5: Resume the flash spray cleaning operation and turn on the standby flash spray function.

Specifically, when an inkjet printer with the standby flash spray function enters the standby state, it will automatically start the flash spray cleaning operation, that is, control the nozzle to spray ink once or more at intervals to ensure that the nozzle of the nozzle is wet and prevent the nozzle from clogging. During flash printing, the piezoelectric crystal in the nozzle exerts pressure on the ink to make the ink ejected from the nozzle. When the ink is pressed, the pressure pump in the ink supply system generates pressure to apply to the ink to make the ink stay out of the nozzle. In order to prevent damage to the nozzle due to excessive pressure applied to the nozzle, it is necessary to turn off the flash cleaning during the ink pressing operation. Then the control system of the inkjet printer needs to obtain the signal to start the ink pressing operation. After obtaining the signal, first judge whether the flash cleaning operation is being performed. If the flash cleaning operation is being performed, first stop the flash cleaning operation at the same time Turn off the standby flashing function (turn off the standby flashing function to prevent the control system from triggering the flashing cleaning operation in the standby state again after a period of time during the ink pressing process), and then perform the ink pressing operation, if the flashing cleaning is not currently performed Operation, first turn off the automatic flash spray function, and then drive the ink supply system to perform the ink pressing operation. After the ink-pressing operation is performed, the inkjet printer control system obtains whether there is an ink-pressing signal again, that is, multiple times of ink-pressing are required. If so, continue to drive the ink-jet printer ink supply system to perform the ink-pressing operation until the ink-pressing operation After the execution is completed and the ink pressure signal is no longer obtained, restart the flash cleaning operation, and at the same time turn on the standby flash function, let the inkjet printer control the nozzle to spray ink once or more times at intervals to ensure that the nozzle of the nozzle is wet.

The ink pressure signal can be any one of the ink pressure switch signal, the ink path positive pressure sensor signal or the preset ink pressure signal generated by the inkjet printer control board, wherein the ink pressure switch signal is determined by the pressure of the ink supply system of the inkjet printer. The ink switch is generated, and the ink path positive pressure sensor signal is generated by the positive pressure sensor in the ink supply system of the inkjet printer. When the ink pressing operation is required, the ink pressing switch is triggered, and the switch signal of the ink pressing switch can be sent to the control system as the ink pressing signal. In some other embodiments, the ink pressure switch may trigger the ink path positive pressure sensor in the ink supply system to generate an ink pressure signal and send it to the control system. In some other embodiments, the PLC module in the control system of the inkjet printer may generate a preset signal as the ink pressure signal when the ink pressure switch is detected to be triggered. After obtaining the ink pressing signal, the control system stops the flash cleaning operation and turns off the standby flash function, and then drives the ink supply system of the inkjet printer to perform the ink pressing operation.

In one embodiment, the inkjet printer performing the ink pressing operation includes the following steps:

Control the positive pressure pump in the ink supply system of the inkjet printer to generate positive pressure;

Applying the positive pressure to the ink path connected to the printhead causes the ink to flow out of the nozzles of the printhead.

The ink supply system of the inkjet printer in this embodiment is a negative pressure ink supply system. In the non-working state, the ink path is in a negative pressure state to offset the pressure difference caused by the height difference between the auxiliary ink bottle and the nozzle, and then prevent leakage. The phenomenon of ink and ink overflow; in the state of ink pressure, the positive pressure pump of the negative pressure ink supply system generates positive pressure, so that the ink path is in a positive pressure state, so that the ink is pushed to the position of the nozzle and flows out from the nozzle; during the printing process Among them, the negative pressure ink supply system is in a negative pressure state and the pressure position is at a fixed value, which is conducive to the uniformity of ink ejection from the nozzle during printing and improves the quality of printing.

In one embodiment, the ink pressure signal is generated by detecting whether the ink pressure switch in the inkjet printer is triggered, and when the ink pressure switch is triggered, the ink pressure switch generates the ink pressure signal. This method is suitable for the application scenario of manual operation. For example, when printing short lines are found during the printing test, the printing is suspended, and the ink pressing switch is manually triggered to perform the ink pressing operation.

When it is necessary to perform multiple ink pressing operations, set a time interval and record it as the first preset time. When the time interval between the two ink pressing switches is triggered is less than the first preset time, the next time the ink pressing switch is triggered No ink-pressing signal is generated; when the time interval between two triggering of the ink-pressing switch is greater than or equal to the first preset time, the ink-pressing signal is generated when the ink-pressing switch is triggered the next time. In this way, the ink pressing switch can be prevented from being frequently triggered, causing the next ink pressing signal to be generated and transmitted to the control system when one ink pressing operation is not completed. Preferably, the first preset time is equal to the duration of the ink pressing operation. In some other embodiments, instead of setting the first preset time, the ink pressing signal generated by each ink pressing switch may be directly recorded, and the number of ink pressing operations is performed according to the number of ink pressing signals. Input the ink pressure signal generated by the ink pressure switch into the inkjet printer control system. After the ink pressure signal is obtained, the inkjet printer control system judges whether the inkjet printer is performing the flash cleaning operation, and if so, interrupts the flash cleaning operation and After turning off the standby flash printing function, drive the ink supply system to perform the ink pressing operation.

In one embodiment, the number of abnormal nozzles in the nozzle of the inkjet printer is detected in the standby state. When the number of abnormal nozzles is greater than or equal to the first preset value, the control system of the inkjet printer generates an ink pressure signal, and the pressure is obtained. After the ink signal, the inkjet printer control system judges whether the inkjet printer is performing the flash jet cleaning operation, and if so, interrupts the flash jet cleaning operation, and then drives the ink supply system to perform the ink pressing operation. The detection of abnormal nozzles in the nozzle can be determined by printing the status diagram of the nozzle. The status diagram of the nozzle shown in Figure 2 is a test diagram designed to determine the status of each nozzle in each nozzle, by detecting the missing or abnormally printed lines. The position and quantity can determine the quantity and position of abnormal nozzles; in addition, the nozzles in the nozzle can also be directly detected by sensors to obtain the position and quantity of abnormal nozzles; the specific method is not specifically limited here. This method does not require manual operation. The control system of the inkjet printer automatically detects the number of abnormal nozzles. When the number of abnormal nozzles is greater than or equal to the first preset value, the control system of the inkjet printer generates an ink pressure signal. Whether the inkjet printer is performing the flash cleaning operation, if so, interrupt the flash cleaning operation and turn off the standby flash function, and drive the inkjet printer ink supply system to perform the ink pressing operation.

In one embodiment, the number of abnormal nozzles in the nozzle of the inkjet printer is detected in the standby state. When the number of abnormal nozzles is greater than or equal to a first preset value, the inkjet printer control system generates an ink pressure signal. Further, Detect the content of dry ink and/or air bubbles in abnormal nozzles, and dynamically adjust the ink pressing power according to the content of dry ink and/or air bubbles. As shown in Figure 3, the abnormal nozzle is blocked due to ink drying at the nozzle. The more ink drying, the greater the pressure on the ink when unblocking the nozzle. In addition, the ink in the nozzle may also contain Bubbles of different sizes, because the bubbles contain air, have a certain pressure, the content of the bubbles is different, and the pressure is different. In order to more accurately remove the bubbles and clear the clogged nozzle, the pressure can be dynamically adjusted according to the content of dry ink and/or bubbles. Ink power, that is, to dynamically adjust the pressure applied to the ink, so as to more effectively clear the nozzle and eliminate air bubbles.

In one embodiment, the bubble content of the ink in the ink path of the inkjet printer is detected in the standby state, and when the bubble content is greater than or equal to a preset value, the control system of the inkjet printer generates an ink pressure signal. After obtaining the ink pressing signal, the inkjet printer control system judges whether the inkjet printer is performing the flash cleaning operation, and if so, interrupts the flash cleaning operation, and then drives the ink supply system to perform the ink pressing operation. The detection of the air bubble content can be carried out by ultrasonic air bubble detection technology, which is a prior art and will not be repeated here. This method does not require manual operation. The inkjet printer control system automatically detects the bubble content of the ink in the ink path. When the bubble content is greater than or equal to the preset value, the inkjet printer control system generates an ink pressure signal. Whether the ink printer is performing the flash cleaning operation, if so, interrupt the flash cleaning operation and turn off the standby flash function, and then drive the ink supply system to perform the ink pressing operation. In one embodiment, the inkjet printer control system will detect whether the inkjet printer is in the standby state at intervals, if so, the inkjet printer control system will generate an inkjet printer signal, and after obtaining the inkjet printer signal, judge whether the inkjet printer Whether the flash cleaning operation is being performed, and if so, interrupt the flash cleaning operation and turn off the standby flash function, and then drive the ink supply system to perform the ink pressing operation. This method also does not require manual operation. The inkjet printer control system drives the ink supply system to perform the ink pressing operation at intervals of a preset time, so as to avoid the accumulation of air bubbles in the ink path when the inkjet printer is on standby for a long time and affect the printing effect of the printing work. .

To sum up, the inkjet printer ink pressure control method provided by the embodiment of the present invention, when the ink pressure signal is obtained, stops the flash cleaning operation and turns off the standby flash function until there is no ink pressure operation, and then resumes the flash printing operation. Spray cleaning operation and standby flash spray function, so as to prevent the inkjet printer from performing the flash spray cleaning operation while performing the ink pressing operation, which will cause damage to the nozzle, and obtain a better ink pressing and cleaning effect. In addition, the inkjet printer ink pressure control method of the embodiment of the present invention also realizes the automatic ink pressure operation in the standby state, when the abnormal number of nozzles in the nozzle is detected or the ink bubble content in the ink path is greater than or equal to the preset value or at intervals Automatically perform the ink pressing operation at a certain time, so as to avoid the accumulation of air bubbles in the ink path when the inkjet printer is in standby for a long time and affect the printing effect, and improve the printing quality of the inkjet printer when it is working.
