Everything You Wanted to Know About Automatic Screen Printing Machine

Automatic Screen Printing Machine

Introduction

In the past, the screen printing process was all printed by hand. With the development of the era of automation, the screen printing process has become more and more automated. The fully automatic screen printing machine is named according to the degree of automation of the screen printing machine. Auto screen printing machine is a development trend of screen printing machine after manual screen printing machine and semi-automatic screen printing machine. It uses more advanced technology and technology to make the screen printing process more accurate, faster, and more automated.

What is automatic screen printing machine

First understand the four major printing methods, namely lithographic printing, embossing, gravure, and stencil printing, while stencil printing includes transcription, hollow pattern, spray, and screen printing. Therefore, an automatic screen printer is a machine for screen printing. Automatic screen printer is a machine that prints text and images. It is a general term for machines used to produce printed matter.

Working principle of automatic screen printing machine

The automatic screen printer uses the basic principle that the graphic part of the screen printing plate is ink-permeable and the non-graphic part is not ink-permeable for printing. The auto screen printing machine pours ink on one end of the screen printing plate and uses a squeegee to apply a certain pressure on the ink position on the screen printing plate while moving toward the other end of the screen printing plate. The ink is squeezed from the mesh of the graphic part to the substrate by the squeegee while it is moving. Due to the viscosity of the ink, the imprint is fixed within a certain range. During the printing process, the squeegee is always in line contact with the screen printing plate and the substrate, and the contact line moves with the movement of the squeegee. The screen printing plate is in mobile line contact with the substrate, while the other parts of the screen printing plate are in a disengaged state from the substrate. The ink and the screen are broken to ensure the printing dimensional accuracy and avoid smearing the substrate. When the squeegee is scraped across the entire layout, it is lifted, and the screen printing plate is lifted at the same time, and the ink is gently scraped back to the original position. So far is a printing process of the automatic screen printing machine.

Features of automatic screen printing machine

  1. First of all, the automatic screen printer has its own unique frequency conversion speed regulation device, the printing speed can be adjusted, from 20 to 70 times per minute auto screen printing machine.
  2. Secondly, the auto screen printing machine has its own electronic counter, which can automatically shut down according to the pre-designed total number, saving a lot of manpower and financial resources.
  3. Third, the automatic screen printer is very accurate in point and color, because it is equipped with a multi-color printing electric eye device, which can improve the quality of printing.
  4. Fourth, large-area background color, outline dots, and fine-character patterns are suitable for screen printing machines, because the high quality of the automatic screen printer not only makes the patterns clear, the colors are bright, and it is not easy to fade.
  5. Fifth, the reason why the pattern printed by the auto screen printing machine is bright and clear is that the ink adhesion of the screen printing machine is very good, and the ink layer is relatively thick, so the pattern is not easy to fade.
  6. Sixth, the fully automatic screen printing machine can not only be used alone, but also can be connected to a UV dryer, or a slitting machine, a reminder, and other auxiliary machines.
  7. Seventh, because of the high-quality configuration of the automatic screen printing machine, there are also a lot of savings in consumables.
