The machine is controlled by microcontroller,and Non-contact inkjet marking system. Through the control of the internal gear pump or via machine external supplies of compressed gas to the system in a certain pressure, and make the ink via a few microns diameter nozzle injection.And by crystal oscillator signal above the nozzle will shoot straight chalk line divide into the same frequency, they are equal in size, spacing certain, then drops after charging electrodes are respectively when charging, the charge size controlled by the central processor, the CPU;After detecting electrode drops with actual power and phase is correct or not;Finally, charged drops deflect in deflecting electrode formation deflecting electric field, shooted from the injection nozzle respectively in different location of the product surface, and forming a variety of text, pattern and so on. While no charged drops are dropped into the recycling tank, and let them back into the ink circulation system inside the machine.
