Printing classification and working principle of automatic screen printing machine is what Automatic screen printing machine printing, silk screen printing not only adapt to regular paper and wide adaptability. For example: ceramics, glass, printed circuit board, etc. Depending on the quality of a material of substrates, printing is not the same, although each series has close inner link between, but because of the printing material to different (i.e., different chemical and physical properties), each has its own particularity. So often people according to different substrates are divided into: paper printing, plastic, glass, ceramic printing printing printing, circuit board printing, metal, printing, textile printing, such as several major categories. Thus formed their own relatively independent system of printing. The working principle of automatic screen printing machine: Fully automatic screen printing machine consists of five elements, the screen printing or silk screen plate, scraping scraping plate, printing ink, printing machine, and substrates. Silk screen printing basic principle is: use silk screen printing ink plate picture and text part of the mesh, the graphic part of the mesh is not through the basic principle of ink to print. In silk screen printing on the plate at one end into the ink, scrape printing scraper ink on silk screen printing position a certain pressure, moving in silk screen plate at the other end at the same time. Ink scraper in moving from the graphic part of the mesh extrusion on the substrates. Due to the effect of viscosity of the ink fixation within a certain range, and make the mark scraper is always in the process of printing and silk screen printing and printing substrates in line contact, the contact line with scraper and movement, due to silk screen printing plate and keep some space between the substrates, makes the screen plate through own tension when printing and reaction of scraper, the reaction is called elastic back. Due to the effect of elastic, causes the screen plate and substrates are mobile line contact, only the silk screen plate break with substrates for the rest of the state. Fault movement in the ink and mesh, ensure the dimensional accuracy and avoid smearing printing substrates. When raised after the whole layout of scraper, silk screen printing plate also raised, and the light ink scraping back to the initial position. At this point for a fully automatic screen printing machine printing. |
