the form roller 30 and the water form roller 50 are each clutched to the plate cylinder 10 by a form roller 30 clutch and a water form roller 50 clutch when the outer diameter of the plate cylinder 10 is constant. The piston rod of the gap bridge roller clutch cylinder 70 of the gap bridge roller clutch mechanism extends out to drive the gap bridge roller swing arm 71 to swing, so that the gap bridge roller 60 is respectively pressed with the water applying roller 50 and the ink applying roller 30, and the connection of a water path and an ink path is realized. When the pressure between the bridge roller 60 and the inking roller 30 needs to be adjusted, the two adjusting bolts 33 in the inking roller pressure adjusting mechanism are adjusted, so that the backrest 32 transversely moves on the sleeve plate 312 of the adjusting block 31, the backrest 32 abuts against the cylindrical section 61 of the bridge roller bearing seat 6 to move the bridge roller bearing seat 6, the distance between the axis of the bridge roller bearing seat 6 and the axis of the inking roller is adjusted, and the pressure between the bridge roller 60 and the inking roller 30 is adjusted. When the pressure between the bridge roller 60 and the dampening roller 50 needs to be adjusted, the worm 82 drives the worm wheel 81 to rotate by adjusting the hand-screwed nut 80 in the dampening roller pressure adjusting mechanism, and meanwhile, the bridge roller bearing seat 6 also rotates for a certain angle along with the worm wheel 81 so as to adjust the distance between the axis of the bridge roller bearing seat 6 and the axis of the dampening roller 50, and further adjust the pressure between the bridge roller 60 and the dampening roller 50. The separation of the water path and the ink path can be realized by the gap roller 60 by driving the piston rod of the gap roller clutch cylinder 70 to retract.
The form roller 30 and the water form roller 50 are each clutched to the plate cylinder 10 by a form roller 30 clutch and a water form roller 50 clutch as the outer diameter of the plate cylinder 10 changes. At this time, the piston rod of the intermediate roller clutch cylinder 70 of the intermediate roller clutch mechanism extends out by a corresponding length according to the outer diameter of the plate cylinder, so that the intermediate roller 60 can be respectively pressed with the inking roller 50 and the inking roller 30, that is, the connection of the water path and the ink path is realized. The pressure between the bridge roller 60 and the ink form roller 30 is then adjusted by the ink form roller pressure adjustment mechanism, and the pressure between the bridge roller 60 and the ink form roller 50 is adjusted by the ink form roller pressure adjustment mechanism.
