Shenyang Oulans explains the working principle of various types of inkjet printers. In our current market, there are several types of inkjet printers, such as small character inkjet printers, large character inkjet printers and laser printers. Machine, according to the user's working principle of different types of printers, we will explain them one by one.
First, the working principle of small character inkjet printer
The small character inkjet printer is different according to the manufacturer's production conditions. The inside is divided into continuous inkjet printer and drop-on-demand inkjet printer (it is also called high solution in our printer name). Like printers and high-definition printers, etc.)
We follow the sequence to understand the continuous inkjet printer. The continuous inkjet printer mainly prints ink through a single nozzle at a pressure, and breaks through crystal oscillation to form an ink dot. The ink dot passes through the charging electrode. In the form of charged offset of the ink droplets, the ink dots are charged and deflected by high pressure to shift the ink out of the normal circulation route, so that the ink is directly sprayed out of the nozzle, and then printed on the surface of the product, which is added here, if not The ink droplets will not be charged, so there will be no deflection. It will be directly driven into the recycling tank and will be used again.
The high resolution inkjet printer has a lot of points in the drop-on-demand printer. It is mainly light in equipment, convenient to operate or maintain. It uses the ink cartridge without solvent, and only a small amount of maintenance. The cleaning solution can be used. And physical characters, dot matrix characters, or high-resolution images can be printed.
Second, the working principle of large character inkjet printer
The working principle of the large character inkjet printer is very similar to that of the small character inkjet printer. The difference is that the ink is ejected differently. The large character ink ejection method uses a separate valve to control the switch, for example: 7 The nozzles at the point are 7 independent valve controls. The typeface printed on it is relatively large, and is generally used in production for outer cases and packaging, or for large workpieces. Large character printers are available in handheld and desktop mount versions.
Third, the working principle of laser printer
Laser printers are now used in production by many companies, so they are not very strange to laser printers. In our current market, laser printers are mainly in the form of dot matrix and scribe. The laser machine, in which the scribing type machine is still relatively commonly used, works on the principle that the characters to be marked are completely scribed according to the trajectory. The dot matrix machine is to mark some important track points of the characters to be identified. Therefore, under the same energy, the new dot matrix laser printer will work faster.
Laser printers and inkjet printers work in a very similar way. The main thing is to change the ink to CO2 laser light. The laser is concentrated on the surface of the marked product according to the extremely high energy density, and is etched and cauterized to make the surface of the product. Form a font. Accurately engrave the pattern and text, and make the desired graphics and text as you wish within the specified range.
