By operating each cylinder（The drive cylinder 57 of first inking roller, the drive cylinder 60 of the second inking roller, damping roller
Drive cylinder 64）Solenoid valve control button, thus it is possible to vary and control flow into the cylinder compressed air airflow direction, so as to
The expanding-contracting action of the cylinder piston rod is varied and controlled.When the piston rod of the drive cylinder 57 of the first inking roller shrinks and second
During the piston rod elongation of the drive cylinder 60 of ink roller, the first inking roller 28 and the second inking roller 29 swing be close to plate surface and to
Printing plate inking；Conversely, piston rod elongation and the drive cylinder 60 of the second inking roller when the drive cylinder 57 of the first inking roller
When piston rod shrinks, the first inking roller 28 and the second inking roller 29 are then swung away from plate surface round about, and printing plate stops
Inking；Equally, when the piston rod in the presence of the drive cylinder 64 of damping roller extends, the swing of damping roller 32 and be close to plate surface and to printing plate
Dampening；Conversely, when the piston rod in the presence of the drive cylinder 64 of damping roller shrinks, damping roller 32 and be then swung away from printing plate round about
Surface, printing plate stop dampening.Due to each cylinder（The drive cylinder 57 of first inking roller, the drive cylinder 60 of the second inking roller,
The drive cylinder 64 of damping roller）Piston rod collapsing length can change within the specific limits, therefore, changed in the range of certain size
After the plate cylinder 14 and blanket cylinder 12 of different-diameter size, it is not necessary to carry out any adjustment, each inking roller（First inking roller
28th, the second inking roller 29）Can be stably to plate surface dampening inking or from water from ink etc. with damping roller 32.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
