ROTOGRAVURE PRINTING MACHINE-ECONOMY MODEL

Control Panel:

Three drive AC driven automatic web tension control systems : Load cell  based closed loop AC motor control & drive on (1) Unwind (2)  Printing Station (3) Rewind.

Operator interface:

Master operator control panel mainly consists of touch screen operator interface located at rewind side and remote operator control panel located at unwind side, facilitates easy operation from both the end. The  efficient web liner is given for proper web guiding.

Frame Structure:

Distinctively designed and precisely machined, strong and sturdy, steel frame structure completely machined on CNC-VMC, maintains accuracy over long dependable life and ensures less vibration with 25-30 mm thickness even with optimum line speed.

Print unit control panel

Each print unit control panel consists pneumatic controls for impression rubber roller & manual controls for  length and side-lay registration setting, temperature display for drying chamber and emergency stop.

Drying System:

Ink drying is obtained by blowing hot air on the web through air nozzles. The optimized airflow minimizes heat consumption and avoids solvent retention in the printed substrate.

The system mainly composed of single hood drying chambers, ventilation modules, connection ducts, central exhaust system.

Ventilation Module suitable to send and re-circulate the process air. The module composed of AC mtotorized centrifugal fan, thermal oil or electric heat exchanger and necessary controls and feedback device for temperature.

Connection Ducts and piping for the delivery and re-circulation between drying chamber and ventilation module. Adjustment of air balancing by means of manually operated dampers.

Impression Rubber Roll

Pneumatically operated impression rubber roller raising lowering on precision linear bearings. The precision linear bearings ensure smooth and precise displacement.

Pneumatic working impression controls with independent pressure adjustment for both the sides.

Idle Rollers

Specially designed, dynamically balanced low friction-low inertia idle rollers made of Aluminum alloy, mounted on low friction bearings, enhance rotational smoothness.

Doctor blade group

Designed to ensure a straight profile of the blade resulting in lesser blade pressure, better printing quality and longer cylinder life. The blade locking by eccentric rod without tools.

The group allows horizontal, vertical and angular adjustment for the doctor blade position on engraved cylinder. MANUAL mechanism is given for adjustment of Doctor blade.
