The operating principle of active coater for screen printing plate is the same, but its function varies according to different models and different manufacturers. The screen coater is provided with a device that can clamp the net frame on the straight frame. The front AND back of the screen area ARE horizontal coating tissue, which is composed of coating groove, and mechanical or pneumatic components that control the view point and pressure of the coating groove.

The two ends of the coating organization are installed on the straight arm of the coating machine, and the transmission of the belt, chain or cable makes the coating organization move up and down, and the coating along the appearance of the screen. The transmission structure IS connected to the servo or frequency conversion motor, so that it can operate smoothly and accurately control the orientation of the coating structure.

Coating machine manufacturers before coating, the clean, stretched screen from the front of the coating machine loaded, some models can also be installed from the side screen. In the large mesh frame planning models, the side side version is more common, because the mesh frame is large and thick, the side version, can make the lifting and moving momentum is smaller. In the active screen coating machine and other active screen processing equipment (such as cleaning equipment, regeneration equipment, dry equipment and development machine) online operation, from the side version more convenient.

How is the pipe network plate installed, once the screen is in the correct position, pneumatic clamping equipment or mechanical clamping equipment is closed, the screen is determined. To make it easier to operate, many models have pedal-operated plate clamps that allow operators to free their hands to operate the screen. After the installation of the screen, to the precision coating machine into the corresponding emulsion, you can start coating. According to the function of the control system and the equipment, the equipment can be coated on both sides of the screen together.

There are two ways of coating, one is after repeated wet wet operation on the screen coated with photographic emulsion; Or add a boring process after each coating. A machine for quantitatively coating liquid (or melt) polymer materials such as adhesives or coatings on the surface of data.
