The semi-automatic screen printing machine is divided into 1/2 automatic and 3/4 automatic. The 1/2 automatic printing frame and the squeegee are driven by the motor, and the substrate is manually fed and received. The 3/4 automatic screen printing machine is a printing net frame and a doctor blade driven by a motor, and the substrate is manually taken, and the charging becomes automatic.
Semi-automatic screen printing machines have several main components: automatic landing frame fixing, automatic running squeegee fixing, printing platform with vacuum system and material feeding guide system.
There are two different types of semi-automatic screen printing machines, one is a printed frame for closed motion and the other is a printed frame for vertical movement. The latter has many advantages, in addition to easy to observe the feeding and running conditions of the substrate, it is also convenient to control the ink and clean printing at any time.
