In the electrical aspect of the automatic flat screen printing machine, we take the computer and the programmable controller as the core. The industrial computer is the upper computer, and the computer communicates with the single-chip microcomputer system of the printing unit to collect and exchange data and monitor the whole machine. .In terms of software, a graphical computer monitoring software is developed on the basis of Windows, and its interface is beautiful, intuitive and easy to understand Chinese display. In order to improve the reliability of the printing unit.
The ink will not block 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 ink is different in different regions, temperature and humidity. Some say that 90% of the problems in the screen printing process are solvent related. UV ink does not contain volatile substances, the viscosity of the ink changes little, and it is easy to operate, which solves these problems 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 dust contamination is reduced.
It does not contain volatile solvents and has no negative impact on the human body and the environment. At present, in terms of output and variety of screen printing inks, volatile drying solvent inks are the mainstream. Because of its slow drying time, 60% of the solvent will be volatilized during the drying process, which will pollute the environment. Seeking ink with less pollution, fast drying and less energy consumption has become the common goal of people in the printing industry.
The automatic flat screen printing machine is easy and flexible to operate for some thick ink layers and a wide range of substrates. In general solvent ink, the solid content of 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 general ink. If you use thick film screen printing UV ink, the effect is better.
The technology is to apply external force to the dye solution, so that the dye solution is sprayed onto the fabric through the nozzle to form one color spot. Digital jetting or digital jetting is a jetting technology of digital image technology. The digital technology controls the jetting and non-jetting of the nozzle and the movement of the xy direction, which can form a corresponding accurate image on the printed medium.
