Fully Automatic 6 Colour Offset Printing Machine Shaftless Driving
Model OPT660-FLEXO Shaftless Offset (Alcohol Dampening) Intermittent Rotary Label
Printing Machine is a perfect combination of Japanese Hamada
technology and intermittent rotary, vacuum conveying system of our
company. Through close cooperation with Japanese engineer, our
machine has been able to be the leading level, in domestic or even
in the world, on water, ink pressure balancing so that to make the
machine stable in color printing as well as endurance. Compared
with other producer in China our machine are more stable in paper
conveying sue to special designed unwinding and rewinding system;
less wastage for first start-generally 20-30 meters depends on the
skill of the operator but no longer than 40 meters, easy for
operation- training time generally 5 working days; and with wider
range for material production-0.03 to 0.45mm in thickness..
1. Electric Control System: The main control unit adopts imported
electric components, together with CPU via DOS system to control
the servo motors, which ensures the machine, high responding,
accurate towing, easy operating and safe running.
2. Shaftless Driving: The machine uses big capacity servomotors to
guarantee high speed and accurate running and not trouble in
printing roller change.
3. Registration System: Once printing length is input at the main
control unit, every unit will move automatically to the preset
position. Each unit is controlled individually by a motor for
lateral and longitudinal registration. With the direct of CCD
image, the remote registration is enabled without stopping machine
production (Remote control system is an option for this machine and
need to be charged if it is asked by the cpent).
4. Unwinding and Rewinding Parts: The unwinding and rewinding parts
adopts pneumatic shaft with gravity roller to allow varies
material- paper and film to go smoothly as well as helping the
tension control of the machine. On unwinding parts there is
web-guide and paper lacking detector. On rewinding part, film
lamination and waste off device can be equipped.
5. Printing Unit: it uses advanced US ink supplying system to
ensure the shinning of the print. China's first low-speed
differential water supply system, effectively ensuring the high,
low speed of the ink-water balance and color stabipty; water bridge
ink roller by a version in the first ink roller to achieve the
unity of the classic structure of the ink to reach the
pre-equipbrium, significantly reduce paper waste; pioneered use of
floating roller, effectively prevents the ink bars and ghost. The
ink pne is made up of 20 ink rollers and 5 dampening rollers
(Alcohol System). Both film and paper can be printed in this
6. UV Unit: The UV Unit adopts UV pght to ensure a fast dry and
shining printing result.
7. Lubricating System: Automatically cycpng oil-supply system
together with self-lubricate bearings ensures the accuracy and
service pfe of the machine.
8. The computer controlled automatic and manual plate mounting and
dismounting system shortened the plate changing time and increases
the safety level of the machine. ( Plate changing for 6 color only
needs 6 minutes)
The Japanese origin SMC Pneumatic clutch pressure control system
ensures smooth and accurate running of the machine; two way clutch,
makes the PS plate and the water blanket fully pre-inked and then
be pressed which greatly reduces the pre-print paper wastage.
9. 7 o'clock arrangement in the host rollers successfully avoids
the impact of the printing drum to the prints.
10. Plate and print pressure adopts world most advanced Japan
Fujikoshi double four-row tapered three-points suspension bearing
and two-way clutch which makes the PS plate and the transfer
blanket pre-inked fully to reduce the printing wastage.
11. Partition Ink Tank
The machine is equipped with touch screen operation panel at each
unit to ensure the operation of the machine at either printing unit
12. Unit Touch Screen
This machine can also be equipped with automatic registration
system, automatic ink volume control system, corona, flexo coating
or varnishing unit, cold foil stamping, oscillating roller coopng
system and rotary die-cutter unit to enable multifunction of the
machine and to improve marketing competitiveness.
13. Vacuum Unwinding Device(patented, This is optional,the suction
pulpng device prevents scratch and napping caused by the friction
