Inkjet printers, especially small-character inkjet printers, inkjet printer accessories are more scientific and technological, and they also play an important role in the operation of the inkjet printer. Because the small character inkjet printer is based on the CIj inkjet principle, each of its structures and accessories also has its own special function:
Inkjet printer pump: The pump is the core part of the inkjet printer that provides pressure, and is the basic guarantee for the normal operation of the ink circuit system. The bite of each gear allows the ink to move further forward in the penetration, thereby generating an uninterrupted flow of the ink. Under normal circumstances, we simply divide gear pumps into two categories, one is the US micro pump, and the other is the Chinese special pump. The gear pump is formed by the change and movement of the working volume between the pump cylinder and the meshing gear. As a core part of most of the printer accessories, it plays a vital role in the entire ink circuit working system. , Today I will tell you about the inkjet printers used in Videojet, Domino, Imax and other brands of inkjet printers are all US micro pumps, usually in 8 years. The working principle of the machine gear pump, and how to choose and carry out daily maintenance to extend its replacement. Above, a good inkjet printer pump can provide a stable and continuous pressure supply for our ink circuit system. It can be adjusted in time when the circuit indicates the indication. The pressure range can be adjusted in time. The accuracy is very high. The high standard metal and gear are more Chinese. Part of the gear pump of the inkjet printer is modeled on the MIC pump, but considering the cost, there are still some differences in the details of the workmanship, from the line control part to the gear engagement operation, there will be no small differences, but its price is low , So that its market space is also on the rise, usually in about 3 years.
Inkjet printer head: The inkjet printer head is the core part of ink dot splitting and printing. Therefore, the performance of the inkjet printer is closely related to the structure of the nozzle. The quality of the inkjet printer can be said without doubt. The CIJ inkjet printer is a non-contact inkjet marking system controlled by a single-chip microcomputer. By controlling the internal gear pump or supplying compressed gas from the outside of the machine, a certain pressure is applied to the ink in the system, so that the crystal oscillation signal applied above the nozzle divides the continuous ink line into the same frequency, varying size, and separating certain ink droplets. , And then, the ink droplets are charged separately when they pass the charging electrode, and the amount of electricity charged is controlled by the central processing unit CPU; then the detection electrode detects whether the actual amount and phase of the ink droplet are correct; finally, the charged ink droplet The offset electrode is formed on the staggered upper part and deformed, ejected from the nozzle, and hit different positions on the product surface to form various characters, patterns and other marks required. The uncharged ink drops are driven into the recovery tank and re-enter the ink circulation system inside the machine.
The ink system of the inkjet printer: the ink system of the inkjet printer is also the most important part of the inkjet printer, because the most likely failure phenomenon of the inkjet printer in the working process is the failure of the ink system and other faults, so the better inkjet printer The ink system and the electronic system are separate. The ink system of the inkjet printer is composed of ink pump, cleaning pump, various solenoid valves, various filters, mixing cylinders, ink cylinders, solvent cylinders, viscosity detection, liquid level detection, pressure detection, and various pipes and wiring harnesses. From an aesthetic point of view, so many parts are integrated together, it looks messy, so is there any way to improve it? It is easy for printer manufacturers to think of a way to integrate various parts together, which is the so-called spindle design. Inkjet printers like Videojet’s 1000 series and HAILEK’s MX200 are designed from the above viewpoints. It divides the ink system into 3 parts, namely: mixing tank, ink tank and solvent tank. The mixing tank integrates the original ink pump, cleaning pump, various solenoid valves, various filters, various inspection systems, various pipelines and wiring harnesses. Then seal it with a plastic shell. In this way, the ink system is very simple when viewed from the outside, only 3 parts are seen, and the others are invisible! The scientificity and convenience of the ink system are the basis of inkjet printer design.
Mechatronics of inkjet printers: Mechatronics of inkjet printers is also the most important part of inkjet printers. The software operating system of the inkjet printer and the input modification information of the inkjet printer reflect whether the inkjet printer is easy to use. The hardware reflects whether the inkjet printer is stable and reliable, including the inkjet printer panel, mainboard CPU control part, electric eye board, high voltage package, etc., all reflect the stability of the inkjet printer. A good inkjet printer is not only stable and reliable but also easy to use.
