Main features:

1. Auto unwinding unit: Turret type twin channel, unwinding driven by center: adopt

floating roller constant tention with closed loop control. When the unwinding diameter

come to small one, buzzer alarms, the spare roll moves in advance(change roll in running

status). Auto cutting/connecting roll, connecting roll by auto or manual for option.

Equipped with ultrasonic sensor automatic EPC device locates before printing

2. Machine wainscot adopts casting steel structure. Some key parts adopts alloy with

multiple heat-treatment with accurate polishing of CNC.

3. Center impression roller (CI drum) adopts two layer structure with high accurate

surface machining technology. Surface coating layer is more than 100um and diameter

direction jumpiness tolerance within +/-0.008mm.

4. Center impression roller (CI drum) adopts internal chilly water circulation system,

circulating water automatic control the surface temperature in constant temperature,

avoid expansion after heating.

5. Hydraulic auto lock device. Hydraulic lock device to accurately position and fix the

ceramic anilox roller and printing cylinder, in order to ensure the stale printing quality

under high speed without other influences.

6. Plate roller & anilox auto released once machine stopped, and auto positioned to

printing once runs up. While machine temporarily paused during running, independent

driving mode for printing station, anilox roller running for mixing ink in low speed to

prevent the ink drying.
