Technical operation performance of automatic printing machine

In the electrical aspect of the fully automatic printing machine, we take the computer and the programmable controller as the core. The industrial computer is the upper computer, which uses the computer communication method to collect and exchange data with the single-chip microcomputer system of the printing unit and monitor the whole machine. In terms of software, a graphical computer monitoring software is developed on the basis of Windows, with a beautiful interface and intuitive and easy-to-understand Chinese display. In order to improve the reliability of the printing unit.
The ink will not clog the screen, and the concentration is stable, suitable for high-quality printing. Solvent is an important part of screen printing ink, and the performance of the ink is different in different regions, temperature and humidity. It is said that 90% of the problems in the screen printing process are related to solvents. UV ink does not contain volatile substances, the viscosity of the ink changes little, and it is easy to operate, which solves these problems well and greatly improves the printing quality. In addition, due to the fast curing speed of the ink, the residence time of the printed matter in the drying process is shortened, and the possibility of being polluted by dust is reduced.
It does not contain volatile solvents and has no negative impact on human body and environment. At present, in terms of output and variety of screen printing inks, volatile and drying solvent inks are the mainstream. Because of its slow drying time, 60% of the solvent will evaporate during the drying process, which pollutes the environment. Seeking inks with less pollution, faster drying and less energy consumption has become the common goal of people in the printing industry.
For some thick ink layers, the automatic printing machine has a wide range of substrates, and the operation is simple and flexible. In general solvent ink, the solid content of the ink is about 40%, while the solid content of UV ink after curing is close to 100%, which is 2 to 5 times that of ordinary ink. If you use thick film screen printing UV ink, the effect will be better.
The technology is to apply external force to the dyeing liquid, so that the dyeing liquid is sprayed onto the fabric through the nozzle to form color spots. Digital jetting or digital jetting is a kind of jetting technology of digital image technology. Digital technology controls the jetting and non-spraying of nozzles and the movement in xy direction, which can form corresponding and accurate images on the printed medium.
