Printing Unit
Features
Each printing base is independent device, convenient to install.
The way to install plate is pneumatic pressure shaft-less installation, increases efficient of changing plate.
Down press structure of impression cylinder is swing-arm, works with a guide roller to ensure the minimum change of material length in the process of raising and pressing.
Tuning roller is unilateral adjustment.
Doctor blade is pneumatic pressure type device, it can adjust and move in three directions.
Doctor blade is driven by reducing motor,each unit is independent.
Color compensation roller moves up and down with small interval, it works flexibly.
The ink tank is auto-recycling open-type, up and down movements are manual.
Equipped with air cooling device to cool off the temperature of printing materials quickly.
Parameters
The Diameter Range of Plate Cylinder: φ105mm~φ300mm
