Description

Automatic counterpoint printing machine

Technical Field

The utility model relates to a screen printing technical field, concretely relates to automatic counterpoint printing machine.

Background

The screen printing is characterized by that it utilizes the basic principle of that the meshes of image-text portion of screen printing plate are ink-permeable, and the meshes of non-image-text portion are ink-impermeable to make printing, and when the printing is made, the ink is poured into one end of screen printing plate, and a scraping scraper blade is used for applying a certain pressure to the ink position on the screen printing plate, at the same time, the ink can be moved towards another end of screen printing plate, and the ink can be extruded from meshes of image-text portion to printing stock by means of scraper blade. The printing ink is fixed within a certain range due to the viscosity of the printing ink, the scraper is always in line contact with the screen printing plate and the printing stock in the printing process, the contact line moves along with the movement of the scraper, a certain gap is kept between the screen printing plate and the printing stock, so that the screen printing plate generates reaction force to the scraper through the self tension during printing, the reaction force is called as resilience, due to the action of the resilience, the screen printing plate is only in movable line contact with the printing stock, other parts of the screen printing plate are in a separation state from the printing stock, the printing ink and the screen are subjected to fracture movement, the printing size precision is ensured, the printing stock is prevented from being rubbed and smeared, the scraper is lifted after scraping the whole printing surface, the screen printing plate is lifted at the same time, and the printing ink is lightly scraped back to the initial position, so far, a printing stroke is formed.
