Screen printing machine manufacturer: semi-automatic screen printing machine basic working principle

　　Screen printing machine manufacturer: semi-automatic screen printing machine is also a kind of screen printing machine, semi-automatic need one or two people to cooperate with the machine production, such as: product feeding, feeding need manual careful cooperation operation.

　　Basic working principle of semi-automatic screen printing machine:

　　1. The working cycle of semi-automatic screen printing machine is as follows: feed → location → falling → lower → upper → upper → scraping → upper → lower → upper → back → take → take.

　　2, semi-automatic screen printing machine meticulous work: the basic principle of printing is to use the mesh of the graphic part of the screen printing board through the ink, not to penetrate the mesh of the non-graphic part. To print, pour the ink into one end of the screen plate and apply the ink part of the screen plate with a scraper while moving to the other end of the screen plate. The ink is pushed from the mesh of the graphic part to the substrate by the scraper as it moves.

　　Because the viscosity of the ink and the impression is fixed in a certain range, in the printing process, the scraper and the wire mesh plate and the substrate contact, the contact line moves with the scraper, because the wire mesh plate and the substrate maintain a certain gap, the printing wire mesh plate through its own tension produces the scraper retraction. Due to the role of resilience, the screen plate and substrate is only moving line contact, and the screen plate and the rest of the substrate is out of the state. Ink and screen fracture movement, ensure printing accuracy, avoid dirty substrate. When the scraper lifts after scraping the complete page, the screen plate lifts at the same time, and the ink is gently scraped back to the initial position.

　　Can the screen printer print more than one product at a time

　　Plane product positioning can be divided into two kinds: fixture positioning and suction positioning, mainly according to the size of the product and material requirements. With suction positioning, only a single product screen printing. Fixture positioning, is based on the size of the product, small products can be used at the same time together with a number of silk screen, small products can be left more than a few positions on the fixture, you can put multiple products at the same time, one-time printing.

　　Round surface product positioning is mainly fixture positioning, the current market round surface products are single screen printing, did not reach a printing level.

　　So more than one screen printing machine needs to meet two points first is the plane product followed by the product size is relatively small, can print more than one time.
