The screen printing machine is a machine for printing by using screen printing plate, belonging to a kind of printing machine. A screen printer is a machine that prints characters and images, and is a generic name of a machine or apparatus for producing printed matters. Screen printers may be classified as flat screen printers, curved screen printers, rotary screen printers, and the like.

A screen printer generally includes mechanisms for applying ink, printing, and transferring. The working principle is as follows: the characters and images to be printed are made into printing plate, then the printing plate is mounted on the screen printer, then the printing ink is coated on the position on the printing plate where the characters and images are located by manual work or screen printer, then the printing plate is directly or indirectly transferred onto the printing stock (such as woven tape, metal plate, plastics, leather, wood plate, glass and ceramics), so that the printed matter identical to the printing plate can be copied. In a screen printer configuration; the doctor blade is used for scraping ink for screen printing, and the ink is applied to the screen in ink transfer. However, the scraper in most current screen printing machines is pushed by a pneumatic device, so that the movement speed of the scraper is not uniform, the printing quality of the printing product is not uniform, and the printing quality of the screen printing machines is limited.
