computerized Rotogravure Printing MachineShaftless printing cylinders.
Mitsubishi PLC, KESAI registration system.
computerized Rotogravure Printing Machine
Features: this is a inexpensive computerized rotogrvaury printing machine
1. The central computer employed a color monitor for touch screen operation and top control software. In fixed period displays performance and production parameters. Industrial computer give synchronous control of all unwinder, rewinder and all guide roller¡¯s speed.
2. Employed an automatic registration controller. Stable, reliable and easy to operate. The registration and checking sensors have high resolution and very sensitive, widely fits most materials.
3. Overprint system realized automatic substrate alignment: Auto initial alignment -- slow memory alignment -- high speed alignment.
4. Unwinder & infeed control system includes magnetic powder tension ,double shafts and air shaft etc.
5. The rewinding & outfeed control system includes torque motor,double shafts and air shafts etc.
6. Printing station: Shaftless printing cylinder to insure easy exchange. Doctor blade may work transversely and realized ink circulation.
7. Drying system adopted closed drying chambers. High efficiency and environment reserving. After printing cooling device is water cooling roller.
8. Main transmission system is built up with motors with V. F drive, gearbox with flexible axis, print station oil dipping type high accuracy gearbox, etc.
9. All pulling rollers, impression rollers, drying chamber and doctor blades use pneumatic systems for automatic control.
10. Verso printing system is optional.
