The pad printing machine is a concave plastic head printing device that has become a major method for surface printing and decoration of many objects. Suitable for plastic, glass, metal, electronics, etc. The working principle of the pad printing machine firstly etches the graphic to be designed on the printing plate, sprays the ink on the etching plate, and then, by means of the silicone head, transfers a large amount of ink to the article to be printed.
There are many ways we can spray ink on the etched plate on the pad printing machine. We can first apply ink on the etched plate, then scrape off the excess ink, and scrape it with a retractable scraper. At this time, the solvent remaining in the ink of the etched part will volatilize and form a glue on the surface. After the shape, the glue head will be lowered, and the etched plate will absorb the ink.
When a large amount of ink of the etched plate absorbs the rubber head, it will rise. At this time, some of the ink will be volatilized, and then some of the ink that is not dried will be more convenient for the printed matter to be tightly combined with the plastic head. real. The shape of the plastic head needs to be a rolling action in order to exhaust excess air from the etched plate and the ink surface.
The development of pad printing machines towards automation is a common idea in the industry. This is the fundamental way to improve production efficiency and reduce costs, and is also an inevitable way to change printing technology from labor-intensive industries to technology-intensive industries.
Nowadays, a highly automated pad printer is more commonly a rotary-type pad printing machine, and its printing process is fully automated. Affected by the degree of automation, most companies are still not perfect in considering the quality problems associated with the printing process. Even with such a pad printing machine, there is still a long way to complete the real automated printing. The way to go.
