Printing machine-work principle

1, screen printing works

To common of hand shaped network version plane silk printing machine for cases, can on screen press of work principle for following description: by drive institutions passed power, let scraping ink Board in movement in the extrusion ink and screen printing version, makes screen printing version and printer real formed a article pressure printing line, due to screen has tension N1 and N2, on scraping ink Board produced force F2, back stretch makes screen printing version except pressure printing line outside are not and printer real phase contact, ink in scraping ink Board of extrusion force F1 role Xia, through network hole, from movement with of pressure printing line leak printing to printer real Shang.

In the process of printing, screen scraping for relative motion, force F1 and rebound F2 also moved in tandem with the screen in the presence of resilience, timely return and disengagement of the substrate, so as not to get dirty marks. Screen printing stroke and continuous deformation and resilient.

Scraping unidirectional printing is completed after the screen out of the substrate, and return back to Mexico to complete a print cycle. After ink substrate on screen opposite the distance called the same version or net margins generally should be 2~5mm. Manual printing, technique and proficiency of workers directly influence the formation of the NIP. Screen printing in practice workers have accumulated a lot of valuable experience, which can be grouped into six to ensure that scraping motion straight sex, uniform, isometric resistance, voltage, Center, and the vertical side. That is, printing Shi scraping ink Board should line forward, cannot around shaking; cannot Qian slow Hou fast, Qian fast Hou slow or suddenly slow suddenly fast; to ink Board of tilt angle should keep not variable, special to note overcome tilt angle gradually increases of problems; printing pressure to keep uniform consistent; keep scraping ink Board and network box inside on both sides of distance equal; to ink Board and border keep vertical.

2, flat surface screen printing machine works

Flat surface screen printing refers to the cylindrical or conical surfaces with flat screen for screen printing. Under certain conditions can also be the oval face, drum-shaped surface, the arc curved surface screen printing. Dryer fabric surface screen printing machine is to use the flat screen on the surface of the printing machine.

Flat surface screen printing machine works: a-b-shaft bearing c-mosaic bearing wheel bearing. When printing, print screen plate and substrate movement, and scraping is static. Flat screen printing plate clamped on the screen frame flat surface screen printing machine-driven moving at a constant speed, due to friction and are placed on the supporting device of the substrate of rotation. Surface substrate lines at the NIP rate consistent with flat screen movement, achieving scraping printing.
