HRT 4600 High Speed Flexographic Printing Machine With Double Side Closed Doctor Blades
I.The main features:
1. Easy operate, accurate color, long life.
2. Use motors, variable frequency speed control, saving electricity, small running fluctuations.
3. Off printing roll auto stop the ink-running motor, and up-printing roll automatic start running the ink.
4. Use special diagonal-tooth gear, accurate printing size.
5. Two sets of heating devices, including central heating and constant temperature control system for group control.
6. Low roller special steel processing, and special process, and plating thickness of 0.1mm protective layer of hard chromium.
7 Alloy roll with hard oxidation, treating by dynamic balance, static balanced.
8 With cold wind bellows, and can effectively prevent produce with ink adhesion after printing
9. Print produce are clear and good arrangement quality.
10. Bearing: NSK, Japan Brand, Germany ASNU aluminum alloy roll

III. Major configuration
The Controlling System
- The operator can preset printing numbers on the auto-counter and the machine will stop at the preset number.
- The machine will stop at non-feeding.
- Tension Control System；Register color by manual
Unwind and rewind
- Machine should have one unwind and DOUBLE rewind
- Material holder use air shaft
- Unwind with auto deviation correction system (EPC)
- Powder brakes for unwind system
- Powder coupling for rewind system; MOTOR CONTROL
Printing
- Low speed and full load startup; stable running by tension control when increasing and decreasing speed; noise is decreased
- Aluminum roller adopts the Japan semi-sealing small bearing; flinty oxidation, static and dynamic balancing treatments are conducted; low resistance and small flop.
- The special made modulus angular gears adopted; accurate printing size and full printing specifications (6.35mm is a spec)
- Doctor blade system and circulating pump
- The grouped and controlled bottom roller processed with Germany particular steel materials processed with special techniques and electrically gilded with 0.1mm hard chromium protective layers
- Quick good quality of ceramic anilox roller
- The machine use hydraulic printing-roll loading system which can automatically load printing rolls and run inks after the machine alarm working signal.
- Good quality printing
- Brilliance color appearance.
- The operation is easier and more convenient,the register is more accurate,and the lifespan is also longer
Dryer
- With the air exhaust, blowing and heating settings; the heating system adopts the central thermostatic control system and group management.
- With the cold air forming devices
- With 950w centrifugal blower (9 pcs)
- With 750w centrifugal blower (18 pcs)
