How Do Different Types Of Inkjet Printing Printer Machine Work?

Working principle of continuous inkjet technology Under pressure, ink enters the spray gun. The spray gun is equipped with a crystal oscillator. Through vibration, the ink is sprayed to form fixed intervals. Through CPU processing and phase tracking, some ink dots on the charging electrode will be charged with different charges, and then pass through a high voltage magnetic field of several thousand volts. Different offsets occur under the nozzles, and the flying nozzles fall on the surface of the moving product to form points, thereby forming text, numbers or graphics. The rest of the ink dots are not charged and will not shift, and are directly injected into the recycling tank, where they are recycled and reused. The working principle diagram of the inkjet printer. Under the pressure of the ink supply pump, the ink flows from the ink tank through the ink pipeline to adjust the pressure, viscosity, and enter the spray gun. As the pressure continues, ink is ejected from the nozzle. When the ink passes through the nozzle, it is broken into a series of continuous ink droplets with the same spacing and the same size under the action of the piezoelectric crystal. The jetted ink stream continues to move downward and passes through the charging electrode to be charged. In the charging electrode, the ink droplets are separated from the ink line. The charged and deflected ink drops fall onto objects passing in front of the vertical nozzle at a certain speed and angle. The information to be printed is processed by the computer motherboard, changing the charge carried by the ink droplets, and then different identification information can be generated.

(2) Inkjet printer machine based on the working principle of drop on demand inkjet technology are divided into three types, piezoelectric inkjet technology, pressure valve inkjet technology, and thermal foam inkjet technology.

Piezoelectric inkjet technology: Piezoelectric inkjet printers are also called high resolution inkjet printers or high resolution inkjet printers. On the integrated nozzle, 128 or more piezoelectric crystals respectively control the nozzle plate Multiple spray holes. Through the processing of the CPU, a series of electrical signals are output to each piezoelectric crystal through the drive board, and the piezoelectric crystal is deformed, so that the ink is ejected from the nozzle and falls on the surface of the moving object to form a dot matrix, thereby forming text, numbers or graphics.

Thermal foaming inkjet technology: Thermal foaming inkjet technology, TIJ for short, uses a thin film resistor to heat less than 0.5% of the ink in the ink ejection area to form a bubble. This bubble expands at an extremely fast speed, forcing ink droplets to eject from the nozzle. The bubble continues to grow, then disappears back to the resistor. When the bubble disappears, the ink in the nozzle retracts. Then the surface tension will generate suction, pulling new ink to replenish the ink ejection area. Thermal foam jet printing technology is structured by such an integrated cycle technology program.

Solenoid valve inkjet printer machine (large character inkjet printer): The nozzle is composed of 7 or 16 groups of high-precision intelligent micro-valves. When printing, the characters or graphics to be printed are processed by the computer motherboard and output a series of electrical signals to the intelligent micro solenoid valve. The valve opens and closes quickly, and the ink relies on the constant internal pressure to eject ink dots, and the ink dots form characters or graphics on the surface of the moving printed matter.
