The printer is a non-contact inkjet marking system controlled by a single chip microcomputer. It applies a certain pressure to the ink in the system by controlling the internal gear pump or supplying compressed gas from outside the machine to cause the ink to be ejected through a nozzle of several tens of micrometers. And the crystal oscillating signal applied above the nozzle splits the continuous ink line into ink droplets of the same frequency, equal size and a certain spacing. Then, the ink droplets are respectively charged when passing through the charging electrode, and the amount of electricity charged by the central processing unit CPU Controlling; detecting the actual charge and phase of the ink droplets through the detection electrode; finally, the charged ink droplets are deflected in the deflection electric field formed by the deflection electrode, and are ejected from the nozzles, respectively, at different positions on the surface of the product to form the required Various characters, patterns and other logos. Instead of being charged, the ink droplets are driven into the recovery tank and re-entered into the ink circulation system inside the machine.
Printer development history
The printer is a high-tech product integrating electromechanical integration by using charged ink particles and deflecting by high-voltage electric field to print pattern characters and digital on the surface of various objects. Products are widely used in food industry, cosmetics industry, pharmaceutical industry, automotive and other parts processing industry, wire and cable industry, aluminum-plastic pipe industry, tobacco and alcohol industry and other fields, the machine can be used for printing production date, batch number, barcode As well as trademark patterns, anti-counterfeiting marks and Chinese characters, it is a powerful device for implementing health laws and promoting packaging modernization. The theory of inkjet printers was invented in the late 1960s, and it was not until the 1970s that the world's first commercial inkjet printer was produced. So far, only a few countries, such as Japan and the United States, can produce such printers.
