Inkjet flatbed printer all know, UV flatbed printer the most vulnerable parts of the machine nozzle, then, in

the long-term use, how to maintain a good the nozzle extend inkjet flatbed printer nozzle life, following the
author to introduce some maintenance knowledge.

First, the ink quality, but off, causing the nozzle plug.

Some customers think using flatbed printer ink cost is too high, companies own for some quality, but off the ink nozzle often cause serious obstruction, which is the most serious problem of the quality of the ink,the ink plug factor over the General Assembly is a direct result of nozzle clogging.PLUG factor is a parameter,the pigment particle size and the ink directly associated plug factor if the larger particles are also larger.Ink plug factor in the short term may not find the problem, but with the use incremental filter will gradually be clogged, causing damage to the ink pumps,and even some of the large particles through the filter, causing The Garra permanent blockage, causing serious injury to the Motou.

Second, the impact of the dramatic changes in temperature and humidity on the nozzle and ink

Inkjet flatbed printer flatbed printer manufacturers in the factory will use environment limited to a specifictemperature and humidity, why is there such a limit it? Due to the stability of the ink usage, and the universal flatbed printer nozzle determined by the stability of the ink turn, ink viscosity, surface tension, volatility, liquidity and other factors, and the direct impact of these indicators is not entirely decided Production, storage and use of environmental temperature and humidity are also ink played a decisive role in normal use. Too high or too low temperature will make the ink viscosity decreased or increased many, thus breaking the inkoriginal state. Resulting in the spray painting process often break even erupted screen virtual scattered . On the other hand, if the humidity is too low and the temperature is relatively high will cause the ink to volatile improve ink easy to dry the surface of the nozzle to form a cured, affecting the normal working of the nozzle.If the humidity is too high, the ink may spray around the hole build-also affect nozzle work, and the screen is difficult to dry. To pay attention to changes in temperature and humidity. Nozzle on the humidity is relatively subtle, the nozzle ink amount of the ink chamber is small, the ink is the completion of the siphon phenomenon ink supply process, so the dramatic changes in the outside temperature is very easy to break their original equilibrium state, because the nozzle in the working will generate a certain amount of heat, the ink in this temperature to maintain balance and stability, and this time if the climate the anxious data changes, such as sudden cooling or warming, when the indoor nor thermostat device, then the nozzle affected revealed ink will suddenly not be used, the nozzle can not work properly, you can not use the same ink the same batch.olution: control the temperature, so the production workshops temperature change in a day should not be more than 3-5 degrees.

Third, the voltage of the nozzle sprinklers

The voltage of the print head, because the voltage level of the nozzle can decide the degree of curvature of the nozzle internal piezoelectric ceramic, and thus a high voltage can also enhance the ejection amount as low as possible under the premise does not affect the picture quality. Practice has proved beyond 32V voltage may encounter frequently head off Mexico, and reduce the life situation. said earlier, the curvature of the high voltage causes the piezoelectric ceramic increase, and if there is a high frequency oscillation state, head inside the piezoelectric crystal vulnerable to fatigue and injury break, while too low nozzle voltage will, in turn, affected by the saturation of the picture so more appropriate the nozzle operating voltage between 28V-32V.

Different brands of universal printer nozzle voltage of the same, as the work is machine the nozzle voltage is 37V, the SEB machine nozzle voltage is 35V, the nozzles Yaselan voltage is 33V, different voltage ink viscosity requirements not identical, the nozzle high voltage requirements of the viscosity of the ink is also high, low nozzle voltage requirements of the viscosity of the ink is low, both the proportional relationship.

A nozzle voltage high and low viscosity ink will inkjet excessive, too fast, reflected dots to the nozzle at the bottom of a drop plug nozzle will appear burrs and floating ink phenomenon. B, low and high viscosity ink nozzle voltage appears uneven spray no ink, blocks of color, not full. Solution: replace adapt ink or lower the voltage

Fourth, the electrostatic apparatus and the ink

Substrate and into the roller friction due inkjet printing process is a lot of static electricity can easily affect th normal work of the nozzle can not be ruled out, such as ink drops enough to deviate from its trajectory by static electricity caused the screen out imaginary blooming If static electricity is too large may be damaged and the phenomenon of flying ink. nozzle, and the computer equipment is higher under the influence of electrostatic extremely garbled and the phenomenon of death, even the phenomenon of burning machine circuit board, so take correct and effective measures to remove the equipment. electrostatic extremely important. buried ground line is a good method of eliminating static electricity.

Fifth, work habits sprinklers

Note cleaner straw mouth can not have glitches, in order to avoid scratches during suction nozzle. Sprinklers are most afraid of is dry as long as you want to Do not let the nozzle dry. Protect nozzles is not a good way to plug. The bad use of the ink in the ink for the poor, paste head (find a V-shaped) appear on the screen. Color light gray hair, faded quickly, etc.

Sixth, the ink viscosity is too high

Ink viscosity is too high will cause the ink in inking tube bond insufficient ink supply, inkjet amount is not enough, the color fault. Especially in the winter, the low temperatures, this phenomenon is more prominent.

Solution: raise the indoor temperature (such as air conditioners, dryers, heaters, etc.), the ink viscosity decreases. Or viscosity than the end of the ink.

Seventh, the ink viscosity is too low

Ink viscosity is too low, eco solvent printer the ink is too diluted, on fast speed inkjet ink jet will be reflected back to the nozzle to the light cloth to cause ink smoldering on the nozzle, causing nozzle clogging. A long time to spray the same colors, this phenomenon is more prominent.

Solution: cotton swab stick with a professional cleaning solution to scrub the nozzle. To solve this problem will have to replace the high viscosity of the ink.
