The Working Principle Of Screen Printing Machine.

- May 23, 2018 -

Screen in a commonly used hand flat screen printing machine, for example, can be to make the following description: screen printing machine working principle of the drive gear transmission power, allows the movement of the scraping plate extrusion ink and silk screen printing, silk screen printing plate and the substrates to form a stamping line, N1 and N2, because the screen has tension force F2 scraping board, for back to stretch the silk screen plate except the embossed line is not in contact with substrates, inks in scraping plate under the action of the extrusion of F1, through the mesh, from the movement of the stamping line printing on substrates.

In the process of printing, silk screen printing plate relative motion with scraping board, extrusion and back stretch F1 F2 with synchronous mobile screen under the back stretch, the rallies and substrates from contact, lest the print ceng dirty. The screen is in the printing process, constantly in deformation and rebound.

The scraping board is separated from the substrate by the screen printing plate after finishing the one-way printing, and the return process is returned to the ink, which is to complete a printing cycle. The distance between the substrate and the screen printing plate is called the same plate distance or net distance, generally 2 ~ 5mm. In manual printing, the manipulation and proficiency of the operator directly affect the formation of the embossing line. Screen printing workers in practice has accumulated many valuable experience, the concrete can be summarized as six, namely guarantee linearity in the movement of scraping board, uniform, isometric, equalizer, in neutral and vertical side. That is to say, the ink scraper should be in a straight line, can not sway sway; Slow or slow before and after fast; The inclination Angle of the ink plate should remain unchanged, especially to overcome the general disease with increasing inclination. Printing pressure should be uniform and uniform; Keep the distance between the scraping board and the inside of the net frame equal; The ink plate is vertical to the border.
