Photo printer-ambient temperature and cleaning method affect the life of its nozzle

The viscosity index of the ink will change with the change of the ambient temperature, and the corresponding working voltage of the corresponding photo printer nozzle will change accordingly. Otherwise, the injection of the nozzle will be unstable, and the phenomenon of disconnection and ink breakage will occur easily. When the temperature is high, the viscosity of the ink is lowered. At this time, the working voltage of the nozzle should be appropriately reduced. Otherwise, it is easy to form a bubble inside the ink tube, causing no ink to be ejected from the nozzle, resulting in a white line of the screen. Conversely, when the temperature is low, the viscosity of the ink will increase. If the working voltage of the nozzle is not adjusted, the ink will accumulate inside the ink tube. In a short time, it may be seen as a virtual spray. After a long time, the nozzle is easily irreversible. Damage, serious damage to the nozzle hole. The nozzle works from the beginning, the temperature of the nozzle plate is relatively low, but with the continuous operation of the piezoelectric ceramic, the temperature inside the nozzle plate will gradually increase, and as the ink is continuously ejected, part of the heat will be taken out. Finally, the working temperature of the nozzle will be constant at a fixed range. If you start from the beginning of the nozzle to the constant temperature stage, you need to adjust the nozzle voltage according to the nozzle plate or the ink temperature to ensure the normal operation of the nozzle. Otherwise, the nozzle will be unstable.

For the processing of the digital textile printer nozzle not printing, in the actual printing process, the width of the screen often appears to be smaller than the design width of the nozzle, then the portion of the nozzle that does not come out will not be inkjet. If the ink is sprayed, it will cause a large amount of ink residue to be transported. If the cleaning is not clean, the belt life will be reduced. In addition, because of the interval between the nozzle and the belt, the small ink droplets ejected will drift around with the airflow, flying around the nozzle, and even the control circuit on the nozzle, affecting the normal operation of the circuit part, and being inhaled by the staff is also a great hazard. For this reason, the excess nozzle will not work. If the excess nozzle does not work, the ink in the nozzle nozzle and the ink on the nozzle surface will inevitably cause the ink to dry on the nozzle pipe and the nozzle surface due to volatilization, and the nozzle is blocked. Normally, the nozzle should be cleaned at regular intervals so that the ink in the nozzle tube is in a flowing state.

The effect of the cleaning method on the nozzle. When the ink is ejected normally, the ejected ink droplets will have satellite points, and the satellite dots will adhere to the nozzle surface. As the printing time increases, the satellite dots will increase, thereby forming ink beads on the surface of the nozzle film. If there is damage near the nozzle hole of the nozzle plate, it is not conducive to the diffusion of the ink beads, it will accumulate around the nozzle hole, causing the nozzle hole to be temporarily blocked, and no ink is ejected; if it is not cleaned in time, or the cleaning is not complete, it is possible Causes the ink to dry on the surface of the mouth, speeding up the blockage of the nozzle orifice. In addition, because the cleaning method is not correct, or the cleaning material is incorrectly selected, the nozzle film may be scratched, and the nozzle may be scratched, as if the water is discharged from the faucet. If the water outlet of the faucet is damaged, then The water flow coming out is not under direct current, but is biased out. The same is true for the nozzle inkjet water. Once the nozzle hole is destroyed, it will directly cause irreversible damage to the nozzle. After the nozzle hole is destroyed, the ink around the nozzle hole is more likely to accumulate ink, block the nozzle hole, and shorten the service life of the nozzle. In addition, it also causes oblique spray, which reduces the print quality of the screen.

From the application of the industry, the nozzle of large format digital printing machine manufacturers must have targeted development, in order to better adapt to the industry applications, equipment manufacturers must also have a wealth of nozzle experience, to ensure the cooperation of nozzles and ink, professional manufacturers can provide complete nozzles Maintenance program to extend the life of the nozzle.
