The aluminium foil gravure printing machine is composed of the printing unit, unwinding unit and rewinding unit, they have the same structures. Adopting a frequency motor to drive every unit. Aluminium foil gravure printing machine adopts vector motors for traction and rewinding.
1. Unwinding unit
Gravure printing machine mainly composed of the unwinding roll, automatic turning frame, motor and turning outfit.Riveting the raw material on the unwinding roll when printing,there are motor on the end of the unwinding roll,adjusting the floating roll to control the unwinding tension.
There are bolts installed on one end of the unwinding roll,driving the roll to adjust the winding through tumble axletrees,aiming at rewinding roll worked on one line.
In order to the constant tension of the film when printing,the mini friction air cylinder will control the unwinding tension which be installed beside the unwinding roll.
2. Unwinding traction unit
Unwinding traction is dual-roll style, include in steel roll ,rubber roll and tension controller system. Rubber roll the printing material press on the steel roll tightly when printing, then adjust the tension.
3. Printing unit
Gravure printing machine mainly composed of transmission device, ink filling device, ink scratch device ,press device, tension device, oven device, reverse printing device..
4. Rewinding traction unit
Used for tracting the printing film, when rewinding .Mainly composed of the tracting roll, rubber roll, motors and floating roll. The tension is stable. Motors send the constant power to traction roll. Using rubber roll make the printing film cling on the traction roll. We can set the tension size,and it will automatically keep it.
5. Rewinding unit
Mainly composed of vector motor rewinding seating ,turning frame, turning device and rewinding roll. Tension automatically by the floating roll control and constant, make the handwheel and the winding roll in a line.
