Specific embodiment
The utility model is further clarified with reference to the accompanying drawing.
Fig. 1 is the concrete structure diagram of copy roller ink pressure adjustmenting mechanism.Every copy roller (inking roller I 7, inking roller II
9, damping roller 10) ink pressure adjustmenting mechanism by two sets of copy rollers being symmetrically installed driving cylinders 2, driving swing rods 5, cylinder
Pressure adjusts eccentric ring 12, rolls by version idler wheel 14, copy roller and printing plate between fixed central spindle 11, cylinder connector 4, string roller and copy roller
Pressure adjusts the composition such as eccentric ring 15 and hold-down support 17 between cylinder.String 3 both ends of roller respectively be mounted on the left and right sides frame plate 1
On hold-down support 17 connect, respectively drive in Fig. 1-3 swing rod 5 to be installed on the hold-down support 17 of corresponding string roller 3, copy roller drives
The fixing end of cylinder 2 of taking offence is fixed on frame plate 1 by cylinder fixed central spindle 11, and copy roller drives the activity of cylinder 2
End is then connected on driving swing rod 5 by respective cylinder connector 4；Each copy roller (inking roller I 7, inking roller II 9, damping roller 10)
Roller is gone here and there by a pair to adjust eccentric ring with pressure between copy roller and be mounted on that two sides are corresponding to be driven on swing rod 5；In each copy roller
Under the driving for driving cylinder 2, driving swing rod 5 is rotated around hold-down support 17, and drives corresponding copy roller (inking roller I thereon
7, inking roller II 9, damping roller 10) rise and fall progress from water from ink or dampening inking work.Rotation adjustment two sides string roller and copy roller
Between pressure adjust the eccentric angle position of eccentric ring 12, i.e., changeable string roller 3 and corresponding copy roller (inking roller I 7, inking roller II
9, damping roller 10) between centre distance, that is, adjustment string roller 3 and corresponding copy roller (inking roller I 7, inking roller II 9, damping roller
10) pressure between two rollers, away from becoming smaller, two roll gap pressures become larger at center, otherwise center, away from becoming larger, two roll gap pressures become smaller.String
Roller 3 and corresponding copy roller (inking roller I 7, inking roller II 9, damping roller 10) after two roll gap pressures adjust, the driving of locking two sides
Lock-screw 6 on swing rod 5, the eccentric angle position that two sides adjust eccentric ring 12 would not change again, to guarantee to go here and there
Pressure is stablized constant between roller 3 and corresponding copy roller.During the work time, the corresponding each copy roller in two sides drives stretching for cylinder 2
Contracting is acted need to be synchronous consistent with requirements such as the wobbling actions of driving swing rod 4；Adjustment string roller 3 and each copy roller (inking roller I 7,
Inking roller II 9, damping roller 10) between pressure when, the adjusting rotational angle of the adjusting eccentric ring 12 of two sides also requires corresponding one
Cause, with guarantee each copy roller (inking roller I 7, inking roller II 9, damping roller 10) with go here and there roller 3 it is parallel, it is ensured that each copy roller (inking roller
I 7, inking roller II 9, damping roller 10) two sides pressure it is consistent.Each copy roller (inking roller I 7, inking roller II 9, damping roller 10)
When rising and falling from water from ink or dampening inking, go here and there herein roller 3 and each copy roller (inking roller I 7, inking roller II 9, damping roller 10) between
Pressure will not change.
Two pressure between copy roller and plate cylinder in Fig. 1 adjust eccentric ring 15 be mounted on each copy roller (inking roller I 7,
Inking roller II 9, damping roller 10) two sides are leaned on accordingly in the inner hole of edition idler wheel 14.In printing, each copy roller (inking roller I 7,
Inking roller II 9, damping roller 10) in corresponding copy roller driving cylinder 2 and under driving the pneumatic actuation and control action of swing rod 5 etc.,
The plate surface (referring to fig. 2) being tightly pressed against on plate cylinder 8, and each copy roller (inking roller I 7, inking roller II 9, dampening
Roller 10) on two sides by version idler wheel 14 then on plate cylinder rolling pillow 16 outer round surface be snug against.Rotation adjustment two
Pressure adjusts the eccentric angle position of eccentric ring 15, Ji Kegai between copy roller and plate cylinder of the side at 14 inner hole of version idler wheel
Become the centre distance between the rolling pillow 16 on version idler wheel 14 and plate cylinder, so as to adjust corresponding each copy roller (inking is changed
Roller I 7, inking roller II 9, damping roller 10) and plate cylinder 8 on printing plate between pressure, center away from become smaller then copy roller and print
Pressure between version becomes larger, otherwise center, away from becoming larger, the pressure between copy roller and printing plate becomes smaller.Copy roller (inking roller I 7, inking
Roller II 9, damping roller 10) and printing plate between pressure adjust after, lock pressure between two sides copy roller and plate cylinder adjust it is eccentric
After holding screw 13 on circle 15, the eccentric angle position that pressure adjusts eccentric ring 15 between two sides copy roller and plate cylinder is fixed
It is constant, dampening ink print when on version idler wheel 14 and plate cylinder rolling pillow 16 between centre distance also just immobilize,
To guarantee each copy roller (inking roller I 7, inking roller II 9, damping roller 10) and plate cylinder 8 on dampening between printing plate ink
Brush pressure is constant stablize it is constant.When adjusting pressure at this, also needs to ask and be pressed between the copy roller and plate cylinder that guarantee two sides
The adjusting rotational angle that power adjusts eccentric ring 15 is corresponding to the same, to guarantee each copy roller (inking roller I 7, inking roller II 9, dampening
Roller 10) it is parallel with plate cylinder 8, it is ensured that each copy roller (inking roller I 7, inking roller II 9, damping roller 10) and printing plate between two sides
Dampening inking printing pressure it is consistent.When carrying out printing work, each copy roller (inking roller I 7, inking roller II 9, damping roller 10)
Under the action of the dampening inking printing pressure, energy uniform and stable gives ink waterborne on the plate surface on plate cylinder 8.
Fig. 2 is the utility model at printing work state (i.e. inking dampening), each copy roller (inking roller I 7, inking roller
II 9, damping roller 10), copy roller driving cylinder 2 and the operating position figure for driving swing rod 5 etc..At this time each copy roller (inking roller I 7,
Inking roller II 9, damping roller 10) in corresponding copy roller driving cylinder 2 and under driving the pneumatic actuation and control action of swing rod 5 etc.,
The plate surface being tightly pressed against on plate cylinder 8, and each copy roller (inking roller I 7, inking roller II 9, damping roller 10) on two sides
By version idler wheel 14 (referring to Fig. 1) then on plate cylinder rolling rest the head on 16 surfaces be snug against, guarantee each copy roller (inking roller
I 7, inking roller II 9, damping roller 10) and plate cylinder 8 between dampening inking printing pressure it is constant stablize it is constant.In the dampening
Under the action of inking printing pressure, each copy roller (inking roller I 7, inking roller II 9, damping roller 10) uniform and stable gives printing plate rolling
Ink progress printing work waterborne on plate surface on cylinder 8.
Fig. 3 is the utility model at off working state (i.e. from ink from water), each copy roller (inking roller I 7, inking roller II
9, damping roller 10), copy roller driving cylinder 2 and the driving locations drawing such as swing rod 5.Each copy roller (inking roller I 7, inking roller at this time
II 9, damping roller 10) under corresponding copy roller driving cylinder 2 and the pneumatic actuation and control action that drive swing rod 5 equal, be detached from and print
In 8 surface of plate cylinder and retraction frame plate 1, larger operating space is reserved, to replace various drum operations.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
