Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1 to Fig. 6, the plate cylinder that printing machine at least includes being connected across between the wallboard of both sides and fits successively
10th, inking roller 20 and wavers 30.
The electronic ink roller damping roller clutch of the variable format printing machine of the present invention, including eccentric bushing 4, arm support, adjusts spiral shell
Bar 6, limited block 7, motor 8 and clutch air cylinder 9, wherein：
Eccentric bushing 4 empty set on the bearing block being fixed on wallboard of wavers 30, projection in the outside wall surface of this eccentric bushing 4
One ear climbs 40；
Arm support includes master arm 51, passive arm 52 and the sleeve 50 being connected between master arm 51 and passive arm 52, makes master
Angle between swing arm 51 and passive arm 52 is more than 90 ° and is less than 180 °；The outer end of passive arm 51 is connected to the axle head of inking roller 20
On；Sleeve 50 kink is on eccentric bushing 4；The lower surface of the external end head of master arm 51 opens up the groove 510 of a straight-through upper surface,
And groove 510 two sides open up respectively one connect with groove 510 and bottom be semicircular stopper slot 511；Master arm
One fraising being connected with groove 510 512 (see Fig. 2 and Fig. 3) is also coaxially opened up respectively on the two sides of 51 external end head；
Adjusting screw rod 6 is arranged on the middle part of the master arm 51 of arm support by a spud pile, and this adjusting screw rod 6 is set with one
The ear that helical spring 60 and head are connected to eccentric bushing 4 is climbed in the screwed hole opening up on 40；
A centrally disposed screwed hole of the upper surface of limited block 7, the bottom of the two sides of this limited block 7 corresponds to master arm
Two stopper slots 511 on 51 arrange a cylindrical flange 70 correspondingly, and this limited block 7 is with two flange 70 one by one
The mode in two stopper slots 511 being accordingly embedded on master arm 51 is arranged in the groove 510 of master arm 51 (see Fig. 4
And Fig. 5), by the lower surface of two pieces of external end heads being separately mounted to master arm 51 and be located at the notch of two stopper slots 511
Baffle plate 513, makes the flange 70 of limited block 7 can only move up and down in stopper slot 511.
Motor 8 is fixed on a framed side wallboard of printing machine, and the output shaft of this motor 8 connects a screw mandrel 80, this screw mandrel 80
It is connected with the screwed hole engagement on limited block 7；
Clutch air cylinder 9 is double-acting cylinder；The cylinder body tail end of this clutch air cylinder 9 is fixed on a framed side wallboard, this clutch gas
The external articulation of a hinge 90 passing through fraising and master arm 51 is passed through in the termination of the piston rod of cylinder 9.
The operation principle of the electronic ink roller damping roller clutch of the variable format printing machine of the present invention is：
(change major diameter cylinder or minor diameter cylinder when the diameter change of plate cylinder 10), motor 8 rotates, and makes
Motor 8 drives screw mandrel 80 to rotate, thus order about limited block 7 moving up, when limited block 7 moves to two flange 70 quilts thereon
Stopper slot 511 on master arm 51 blocks when can not move again, just swings with arm support, makes to be connected to the outer end of passive arm 52
Inking roller 20 is fitted on plate cylinder 10 all the time.When the diameter of plate cylinder 10 is fixing, motor 8 does not work, and makes at arm support
Position in plate cylinder 10 clutch being suitable for this diameter.
Because clutch air cylinder 9 is double-acting cylinder, when motor 8 works, the piston rod of clutch air cylinder 9 can be with arm support
Swing and stretch, when the diameter of plate cylinder 10 is fixing, relies on the motion of the piston rod of clutch air cylinder 9, realize inking roller 20
Clutch with plate cylinder 10.
Because, on the bearing block of the fixation in wavers 30 for eccentric bushing 4 empty set, sleeve 50 empty set on arm support is in eccentric bushing 4
On.When rotating adjusting screw rod 6, can compress or discharge helical spring 60, so that eccentric bushing 4 is rotated, make sleeve 50 inner headed face of arm support
Contacting with the peripheral curve of eccentric bushing 4, thus changing the distance between inking roller 20 and wavers 30, reaching regulation inking roller 20
The purpose of pressure and wavers 30 between.
Above example is used for illustrative purposes only, rather than limitation of the present invention, about the technology people of technical field
Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent
Technical scheme also should belong to scope of the invention, should be limited by each claim.
