As an important part of modern automated production lines, multi-nozzle online coding system provides strong support for the identification of various products with its efficient, accurate and flexible coding capabilities. So, how does this system work? The following will analyze its working principle in detail.
The core of multi-nozzle online coding system lies in its precise inkjet technology and control system. When the system starts, it will first initialize to check the status of the ink cartridge and ink to ensure that the nozzle is unobstructed. In this process, the ink enters the spray gun from the ink tank through the ink pipeline to prepare for the subsequent inkjet operation.
The realization of inkjet technology mainly depends on the principle of charged offset or the principle of vibration splitting. Taking the principle of charged offset as an example, the ink forms fixed-spaced ink dots in the spray gun through vibration or pressure, and these ink dots are charged with different electric cores through the charging electrode. Under the action of the high-voltage electric field, the charged ink droplets will deviate and fall on the moving product surface at a certain speed and angle to form a dot matrix, thereby forming the required text, numbers or graphics. During this process, each nozzle is controlled by an independent nozzle plate and piezoelectric crystal to ensure the precise ejection of ink droplets.
The role of the control system is like the "brain" of the multi-nozzle online coding system. It coordinates the ejection behavior of the nozzle, the supply of ink, and the specific content of the code. The user sets the parameters such as the code content, font and size through the operation interface, and the control system converts this information into digital signals and stores it in the memory. When the product passes through the inkjet printer, the control system will accurately control each nozzle to eject according to the preset code content and the moving speed of the product. This process involves high-speed digital circuits and complex data processing algorithms to ensure high accuracy and high speed of the code.
In addition, the multi-nozzle online coding system also has powerful post-processing functions. For example, a protective layer can be applied to enhance the durability of the logo, or special information such as a QR code can be printed to meet industry needs. These functions enable the multi-nozzle online coding system to flexibly respond to different application scenarios and provide more comprehensive and diversified identification solutions.
In summary, the multi-nozzle online coding system, with its sophisticated inkjet technology and control system, realizes efficient, accurate and flexible coding operations, providing strong support for the identification needs of modern automated production lines.
