Main Features of the Machine
WJPS350 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 due 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-0.05 to 0.55mm 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 six color machine uses 25 big capacity servomotors to guarantee high speed and accurate running although it increases our own production cost.
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 client).
4. 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 stability; 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-equilibrium, significantly reduce paper waste; pioneered use of floating roller, effectively prevents the ink bars and ghost generation. The ink line is made up of 20 ink rollers with 4 forming rollers and 4 dampening rollers (Alcohol System). Both film and paper can be printed in this machine.
5. Vacuum Unwinding Device(patented, This is optional. If client do not choose this function we can do roller unwinding system as well): the suction pulling device prevents scratch and napping caused by the friction generated among several parts and printing material. Full version can be printed without blank, which also greatly expands the scope of materials application
6. Lubricating System: the machine uses automatically oil-supply system to ensure the accuracy and service life of the machine.
7. 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)
8. 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 full 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. Pressing roller uses preload, four -line Japanese original P5 level printer-specific tapered roller bearings with radial clearance and beat almost to zero, to ensure stable printing pressure, outlets clearance.
12. The machine adopts thermostatic alcohol dampening units to ensure the brightness of the print. he brightness of the prints is ensured by using thermostatic alcohol dampening device and special water roller motor specially designed and manufactured for offset printing machines by Japanese supplier.
13. Heidelberg ink fountain partition structure, easier to adjust the ink, reducing printing time and paper waste
14. 0.15mm heavy-duty printing pressure setting, gears are ground and modified and assembled after high-frequency quenching, wonderful printings are achieved.
15. The machine is equipped with touch screen operation panel to ensure the operation of the machine at either printing unit
16. This machine can also be equipped with automatic registration system, automatic ink volume control system, flexo press unit, letter press unit, varnishing unit and rotary die-cutter unit, to enable multifunction of the machine and to improve marketing competitiveness.
