Inkjet printer products are now widely used in my country, and more and more industries will use this inkjet technology, which is mainly reflected in shopping places in our lives, usually displayed to us in the form of dates or bars. Today, the editor will introduce the application and development of bar-shaped inkjet printers in our country. With the continuous development of the global economy, the degree of automation and intelligence in industrial production has increased day by day, which has brought good prospects for the consumables of bar inkjet printers. The development of bar-shaped inkjet printers is undergoing many changes, forming a more mature new form today. Bar-shaped inkjet printers are controlled by software to carry out automatic marking and coding in a non-contact manner, which greatly improves the bar code. The working efficiency of machine consumables. It has great advantages in printing countable numbers and changing barcode data, and can have anti-counterfeiting functions. The realization of bar-shaped inkjet printers is mainly concentrated in beverages, auto parts, electronic components, mineral water, Wire and cable, non-staple food, battery and other industries. In the development history of bar inkjet printers, the mechanical equipment control system is a key point, including logic and motion control systems. It has undergone major changes. The development of bar inkjet printers is driven by gas Ink circuit, ink circuit, electric pressure ink circuit system reform, changed from the original air pressure to the current built-in pump control system, and then combined with the remote control inkjet communication system or computer. Built-in pump type bar inkjet printer system , It adopts gear pump drive, the structure is more complicated, the actual pressure is controlled by the servo motor, it can be programmed and controlled, and it can be fully regulated. The third-generation bar inkjet printer is a combination of mechanical and electronic, and the integrated mode and structure are more complicated. , Adopting servo system and simple mechanical equipment, using new technology, better performance and smaller volume. The continuous development of bar inkjet printer consumables technology makes the bar inkjet printer consumables more advanced. The development of inkjet printers will develop towards simpler operation, smaller, faster and higher precision.
