It is obvious that the inkjet printer is used in the food packaging industry, and it is mainly used for software control. Today, with the development of the food industry, there are more and more food packaging bags, and then the technology used in food packaging machines is also constantly improving and the functions are also very rich. Its technical content is also very advanced and the built-in text information is also rich in breakthrough sky. The food packaging machine technology is a world-famous gear pump. Through the high integrated circuit design, the ink circulation system is completely sealed to ensure the reliable operation of the machine. The ink pressure is actively tracked and controlled, and the detection equipment is actively operated and actively controlled. A built-in, second Chinese character in China has a total of more than seven thousand characters, and can output characters through various output methods such as pinyin output method, regional output method, code output method and so on. 240x128 screen backlit LCD display, printing information compiles what you see is what you get. Indirectly edit the ink and pattern through the keyboard, without changing the chip, without connecting to common computer software or applications. Actively print the date, time, batch number, serial number, etc. The most obvious feature of the new food packaging printing machine is energy saving, so this equipment can print 70 million characters per liter of ink processing cost, working capital is expensive, and economical material consumption is only 5 types of traditional gas sources. And spray ink can choose dark, blue, red and other colors. Printing data can be printed on plastic, glass, metal, wood, pipes and external construction materials, etc. Adopting this new food packaging printing machine can not only save more capital enterprises, run stably, and have higher functions. Inkjet printers can be divided into: continuous radial ink jet printers and on-demand printing machines. There are three types of inkjet printers with on-demand ink, piezoelectric inkjet technology, pressure valve inkjet technology, thermal foam and ink.
