Features of the Eight-color Stack Flexographic Printing Machine
1. The printing machine have one unwinder and one rewinder.
2. Slow speed and full load startup; stable running by auto tension control can decrease noise when increasing or decreasing speed.
3. High dots presentation rate; clear and vivid stratification of screen printing; strong stereo effect and accurate registering.
4. Aluminum roller adopts the Japan semi-sealing small bearing; flinty oxidation, static and dynamic balancing treatments are conducted; low resistance and small flop.
5. Adopted special modulus angular gears, so the printing machine can provide accurate printing size and full printing specifications.
6. With the air exhaust, blowing and heating settings; the heating system adopts the central thermostatic control system and group management, also with the cold air forming devices.
7. When the machine is stopped working, printing rolls can still keep moving.
8. Air shaft is used in material holder.
9. The chamber doctor blade system contains ink container and circulating pump.
10.Plastic roller and grain roller are used to smearing the ink.
11.Accurate printing size can be presented by the special vertical gear transmission device.
12. The machine is equipped with blower and heater; and the heater employed central constant temperate controlling system.
13.Germany particular steel material processed bottom roller: The grouped and controlled bottom roller is processed with special techniques and electrically gilded with 0.1mm hard chromium protective layers.
14. The unwinder has auto deviation correction system.
15. One set of printing cylinder (size: 15 inches)
