　　Screen printing machine manufacturer: What are the principle and performance of automatic screen printing machine

　　Silk screen printing machines produce products that are relevant to our lives, such as the glass patterns in our homes, the words and patterns on holiday gift boxes, and the prints on our clothes. Screen printing machine belongs to format printing, which includes copying, engraving, printing and screen printing.

　　I. The basic principle of silkscreen printing machine is:

　　The basic principle of screen printing machine is that the screen printing plate graphic part of the mesh is permeable, non-graphic part of the mesh is permeable.

　　Working process of screen printing machine:

　　1. The screen printing machine prints ink at one end of the screen printing board, and uses a scraper to apply certain pressure to the ink part of the screen printing board and moves to the other end of the screen printing board. The ink is in motion squeezed by the scraper from the mesh of the graphic part to the substrate.

　　2. because the viscosity of the ink is fixed in a certain range, so in the printing process of the screen printing machine scraper and screen printing machine plate and substrate is always in straight line contact, because the contact line will move with the scraper.

　　3. After scraping the entire page, lift the scraper, lift the screen printing machine plate, and gently scrape the ink back to the initial position, so that it is a printing stroke.

　　Two, how about the performance of automatic screen printing machine?

　　1, automatic screen printing machine through photoelectric induction control automatic feed and oven automatic feed, speed can be adjusted at will, effectively avoid the substrate surface scratch, can improve the printing quality.

　　2, automatic screen printing machine using touch screen control, easy to operate, easy to use, realize the whole digital control.

　　3, automatic screen printing machine using PCL computer program control, automatic German SICK photoelectric eye tracking alignment, photoelectric eye precision is high. The second printing adopts photoelectric eye tracking, which can be repeated for many times. The color scale can be detected automatically, and the machine will stop automatically if there is any abnormality.

　　4, automatic screen printing machine adopts precision linear slide rail, effectively ensure the high precision of mechanical movement.

　　5. Automatic screen printing machine uses servomotor to control the motion of scraper and reinking knife as well as the movement of materials. The speed of printing and reinking can be adjusted randomly and specific data can be set.

　　6, large area machine has the function of printing automatically off the grid, printing large area background color, glue and circuit board silver paste, can prevent sticking to the net.

　　7, the net frame can be fine-tuned positioning (adjustable number ±10mm).

　　8, the large-area model touch screen control the lifting of the printing head, convenient screen and scraper maintenance, loading, unloading and cleaning screen is convenient.

　　9, automatic screen printing machine can set the printing speed, calculate the number of printing, and can set the number of automatic stop.

　　10. Automatic screen printing machine adopts two-position (feeding table and printing table are equipped with suction device) three-stage suction, which can adjust strong wind, weak wind and close according to printing materials and quality requirements.
