The Working Principle O The Thermal Foaming Printer (TIJ)

High-Resolution Expiry Date Code Printer / Thermal Inkjet Printer With Double Nozzle Channel

Heat the nozzle of the nozzle through a micro resistor. It is a technique in which ink generates bubbles and is sprayed onto the surface of the leather to realize marking printing, also known as high temperature and high-pressure printing technology.
TIJ's workflow is to use a thin film resistor to instantly heat the ink in the ink ejection area (instantly heated to above 300 ° C) to form a myriad of tiny bubbles that accumulate as large bubbles and expand at an extremely fast rate, forcing the ink droplets from The nozzle is ejected to form the desired text, numbers, and the like.
As the bubble continues to expand, it will disappear and return to the resistor; the bubble will disappear and the nozzle ink will shrink back. Immediately after the surface tension creates suction, the new ink is then replenished to the ink ejection area for the next cycle of printing. Since the ink close to the nozzle portion of the nozzle is continuously heated and cooled, the accumulated temperature is continuously increased, about 30-50 ° C, so it is necessary to use the ink circulation cooling on the upper portion of the ink cartridge. In long-term printing, the ink in the entire ink cartridge, although circulating cooling, remains at about 40-50 °C.
Thermal bubble printing is a technique for printing at higher temperatures, so the ink must be low viscosity and high tension to ensure that the coding equipment can continue printing at high speed for a long time. The inkjet printer with thermal foaming coding technology is generally used in the packaging or carton industry.
