How is the inkjet printer applied in the building ceramic industry

The inkjet printer is an automatic online marking device for marking product information on the surface of the product (or packaging). Inkjet printers are divided into continuous ink supply (CIJ) and on-demand ink supply (DOD). The CIJ system is the small character inkjet printer, while the DOD system is the large character inkjet printer and the high resolution inkjet printer. The small character (CIJ) inkjet printer continuously shoots ink from a nozzle, and divides the ink into many small dots through the oscillation of the crystal, and then is charged by high voltage (generally the charging voltage is several hundred volts), and finally through a high voltage electric field. (Several thousand volts) to form a deflection, thereby completing the scanning of the characters, and finally spraying the characters on the product. Large character (DOD) inkjet printers use solenoid valves, which are generally divided into 7 points and 16 points. According to the needs of the characters, different solenoid valves are opened at different times to eject the ink and finally form the characters. Generally requires external pressure. High-resolution inkjet printers, the principle of character formation is the same as that of large-character inkjet printers. The difference is that high-resolution nozzles have many orifices, most of which are more than 100. The ink supply method is completely different from that of large-character inkjet printers. . Large-character inkjet printers use solenoid valves, while high-resolution inkjet printers no longer use solenoid valves. The ink supply principle generally uses crystal oscillation to form a pressure difference between the crystals. Finally, the ink is squeezed out and sprayed on Product surface. Therefore, the printing distance of high-resolution nozzles generally does not exceed 10mm. The current status of architectural ceramics outer box and product identification Most of the current identification methods used in architectural ceramics are traditional identification methods: 1. When suppressing, the brand of the product , Trademarks and the like are directly pressed on the bottom of the product with a mold; 2. Manual stamping and marking. Defects: The use of mold suppression is not convenient for the development of product diversification. Each product must have a corresponding mold. The manufacturing cost and management cost of the mold are particularly prominent. Manual stamping, manual production speed is low, personnel management is complicated, and output is greatly restricted. Environmental characteristics of building ceramics production site 1. Humidity 2. High dust content 3. Large power noise. Application of inkjet printers in the architectural ceramic industry. As an emerging identification device, inkjet printers have incomparable advantages in architectural ceramic marking: 1. Spray The code machine is controlled by a single-chip microcomputer, and the printing content can be changed and adjusted at any time. Generally, multiple pieces of information can be stored, and the information can be freely edited and modified. 2. It can print numbers, Chinese characters, and trademark patterns. 3. Online labeling is used to label the product information on the product in a timely and accurate manner. Due to the environmental characteristics of the production site of the architectural ceramics industry, it is difficult for small character inkjet printers to be applied and promoted in this environment. The high-voltage electric field of the small print machine is easily broken down in a humid environment, causing high-voltage ignition, breakdown and other failures, high-voltage instability, and unsatisfactory printing effects. Furthermore, large dust and power supply noise are mostly the reasons for the malfunction of the small-character inkjet printer. The dust is large, it is easy to block the nozzle, the power supply noise is large, and it is easy to cause interference, causing the small character inkjet printer to charge inaccurately, and the printing characters are unstable. We have done experiments, and the failure rate of the small character inkjet printer used in the construction ceramics production site is much higher than that in the food and beverage industry. Compared with the food and beverage industry, its failure rate is more than 10 times that of the food and beverage industry. Large-character inkjet printers can solve these problems well due to their fundamental principles. It is easy to use and maintain, and ordinary mechanics can deal with its basic faults well through training. Large-character inkjet printers are increasingly popularized and applied in the building ceramic industry. Now, ceramic automatic production and packaging lines introduced from abroad are equipped with large-character inkjet printers.
