Inkjet Coding & Laser Marking
In the ever-changing industrial production line, every detail is related to the product quality and brand reputation. As a leader in modern industrial identification technology, HP online inkjet printers are becoming the only choice for many companies to improve production efficiency and ensure product traceability with their excellent performance and wide range of application scenarios. Today, let us explore the infinite possibilities of thermal inkjet printers and witness how it illuminates every corner of industrial production with the light of wisdom.
Compared with traditional marking, the non-contact printing method can also be applied to many materials, such as plastic, metal, wood, etc. Even if it is an irregular object surface, the inkjet printer can produce identifiable marks. For these products, a fully automated small character inkjet printer is an important way to solve this type of product identification.
Under the pressure of the ink supply pump, the ink passes through the ink path from the ink tank, adjusts the pressure, viscosity, and enters the spray gun. As the pressure continues, the ink is ejected from the nozzle, and the ink is subjected to the action of the piezoelectric crystal as it passes through the nozzle. Breaking into a series of continuous, equally spaced and identically sized ink droplets, the jet of ink continues to move downward through the charging pole, where the ink droplets are separated from the ink line. A certain voltage is applied to the charging pole, and when the ink droplet is separated from the conductive ink line, a negative electric charge proportional to the voltage applied by the charging pole is instantaneously carried. By changing the voltage frequency of the charging pole to be the same as the frequency at which the ink droplets are broken, each ink droplet can be charged with a predetermined negative charge. Under the pressure, the ink flow continues to move downward, from two separate The deflector with positive and negative voltage passes through the middle, and the charged ink droplets will deflect when passing through the deflector. The degree of deflection depends on the amount of charge. The uncharged ink droplets will not deflect and flow down to the recovery tube. Finally, it is recycled back to the ink tank through the recycling pipe. The charged and deflected ink drops fall at a certain speed and angle onto the object passing in front of the vertical nozzle.
