The machine is composed of a printing host, a screen printing automatic discharging machine and a light-fixing machine on-line. It is a three-quarter automatic screen printing production line with manual feeding and automatic discharging. When the printing host is finished and the printing arm is raised, the mechanical arm of the discharging machine automatically extends between the printing arm and the platform, sucks and pulls the printed product on the printing platform, and sends it to the next process (drying Drying, curing or receiving paper, etc.). While saving manpower, it improves the efficiency of the semi-automatic screen printing machine. This machine is suitable for screen printing of soft materials, such as paper products.
