Understand the working principle of automatic screen printing machine

Screen printing consists of five elements, namely screen printing plate, scraping plate, ink, printing table and substrate. The basic principle of screen printing is to use the basic principle that the graphic part of the screen printing plate is mesh through ink, and the non-graphic part is mesh through ink.

When printing, ink is poured into one end of the screen printing plate, and pressure is exerted on the ink part of the screen printing plate with a scraping plate, and the other end of the screen printing plate is moved at the same time. Ink in the movement of the scraper from the graphics part of the mesh extrusion to the substrate. 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 the rebound, the screen printing plate and the substrate is only mobile line contact, and the other parts of the screen printing plate and the substrate for separation. The ink and screen rupture movement, to ensure the printing accuracy and avoid dirty substrate rubbing. When the scraper scrapes the whole page after lifting, at the same time the screen printing plate is also lifted, and the ink is gently scraped back to the initial position, so far for a printing trip.

What problems can be solved by using automatic screen printing machine?

Everyone can see at a glance that drum carving is much more difficult than flat carving: first, the visual errors caused by curved surfaces should be overcome.

Second, the same thing can't be the same on a curved surface and on a flat surface. Planning screen - reel prints usually contain extremely rich elements, even "visibly open".

Full automatic screen printing machine is called full automatic screen printing machine, screen printing is also one of the printing technology, belongs to the hole printing. So what is the automatic screen printing machine for? What is special-shaped screen printing? There is almost nothing that can't be printed on a fully automatic screen printing machine except water and air. In terms of usefulness, they can be roughly divided into two types.

One is the general type and the other is the special type. Common type is used in many aspects, such as glass, cosmetics cream bottle, lipstick tube, packaging paper, advertising decoration, nameplate and so on. Special automatic screen printing machine, can print PCB circuit board, film circuit board and so on.

Special-shaped screen printing machine, can print non-planar automatic screen printing machine, no matter what shape of objects, can be printed. After professional engineers to customize the fixture, adjust the running state of the machine. Special-shaped automatic screen printing machine can meet the printing needs of various professions. As long as the technical team is strong, no matter what type of objects are printed, they can be customized.
