مبدأ العمل
Substrate is unwound under 50 N·m magnetic-powder-brake automatic tension control(range 3–50 kg) through an EPC(edge position control) device. The web passes through a chrome-plated steel in-feed roller system(130 mm diameter) and rubber pinch rollers(100 mm diameter, 68°–72° Shore) for tension-controlled feeding(3–25 kg range). At each color station(2 total), the shaftless printing cylinder is installed and directly dips into the ink tray(max ink depth 50 mm). The gear-box drives each cylinder. A double swing-arm pneumatic pressure mechanism(max 300 kg) presses the rubber impression roller against the cylinder. The doctor blade(up-down, left-right, and angle adjustable; horizontal movement ±5 mm) controls ink film. Printed substrate passes through a sealed electric-heating closed oven with centrifugal fans for drying. An out-feed traction unit and rewind system(torque motor, max rewindΦ800 mm, tension 3–50 kg) complete the process.
