Factors affecting the printing effect of the treadmill digital direct-injection printing machine

UsedT-shirt personalized custom printingAfter a period of time, color bars may appear in the printed image. Generally, the cause of such problems is "blocked nozzles." Therefore, after understanding the causes of nozzle clogging, it is more helpful to better understand the treadmill digital direct-injection printing machine and improve the quality of the printed picture.

The principle of the nozzle of the treadmill digital direct-injection printing machine is quite similar to that of the pump that is often used daily. The piezoelectric crystal is the soul part of the nozzle, just like the iron rod of the pump. When you find that you can't breathe, there are two reasons: the air path is blocked or the pump iron does not work. Sprinklers are of course much more complicated than pumps, so the reasons for "blocking" are also various, roughly as follows:

1,Piece printing machineAfter the ink accumulates to a certain extent, the nozzles are blocked outside, which is a common way of blocking. Because the solvent in the ink must evaporate into the air to make the picture dry, the ink is a volatile liquid, and solids are easily cleared out in the air. When the nozzle is sprayed on the cloth, some ink will remain around. This part of the ink will gradually become smaller and even block the nozzle after drying in the air. Fortunately, the spray hole is easy to clean on the outside.

2. The piezoelectric crystal is damaged: the nozzle cannot eject ink. Usually the piezoelectric nozzle can be used for about a year, and it may be less than a year in a factory with a large workload.

3. Fatigue damage of piezoelectric crystal: the phenomenon isWhite ink direct injection machineThe nozzle sometimes ejects ink, and sometimes it fails to eject ink, especially when the inkjet volume is large, the "clogging" phenomenon is obvious. At this time, the method is to replace a new nozzle for the treadmill digital direct-injection printing machine.
