Description
Technical field
The invention belongs to rotary offset machine technical field more particularly to a kind of inking damping devices and rotary offset machine.
Background technique
Offset press is to complete printing ink transfer using the immiscible principle of ink and water, and printing plate blank parts are hydrophilic and oleophobic,
Printing plate areas oleophilic drainage, when printing first by damping device damping roller to water on printing plate, then again by the inking device
Inking roller gives printing plate inking, if the ink on printing plate reaches ink-water balance, ink can obtain ideal transfer, thus
Realize that printing picture and text are clear, image hierarchy is abundant, the printing effect of saturation bright in luster and printing blank parts neat and tidy etc..
It will lead to printing if ink is unbalance and occur phenomena such as bad colour, picture and text fuzzy matt, printing product surface set-off.Therefore,
Offset press just must have a set of functional and stable and reliable quality inking and soak to print off the printing product of high-quality
Device.
The inking damping device of offset press includes the inking device and damping device two large divisions, and inking fills in printing process
Set be responsible for it is appropriate to plate surface, uniformly, ink is continuously and stably provided, damping device is responsible for appropriate to plate surface,
It is even, continuously and stably provide wetting moisture.
End gear of the power source of driving inking device work from plate cylinder on usual offset press.Plate cylinder
Rotation by gear drive drive the inking device in wavers rotation, wavers further through frictional drive drive rider roller with
The rotation such as ink roller.Printing when, contacted again with wavers simultaneously since inking roller should contact with plate cylinder, inking roller and
There is frictional drives between the two for plate cylinder and wavers.In order to reduce the mill of each ink roller and printing plate during ink transfer
Damage, while ink emulsification etc. caused by preventing because of friction Temperature Rise, when designing the offset press inking device, it is necessary to assure in the inking device
Between each ink roller, especially between printing plate and inking roller it is the movement relation of pure rolling, that is, guarantees each ink roller and printing plate
The outer round surface linear velocity of roller must be equal.Therefore, if wavers diameter, wavers and print in the offset press inking device
Rotating ratio, that is, gear ratio between plate cylinder does not change, then the plate cylinder diameters of offset press cannot also change.
It is limited by offset press structure, the wavers, wavers gear and plate cylinder gear on generally conventional offset press can not be easy
It rapidly replaces or changes, therefore, a kind of offset press of diameter dimension plate cylinder usually requires to be equipped with respective diameters size
The inking device of wavers, wavers gear and plate cylinder gear.And the size of offset machine printing diameter of cylinder determines this
Offset press can the repeat length size of printing printing also allowed in this way since the dimensions of printed matter in the market is numerous
Offset press is limited by very large when accepting printed matter printed document, can only the repetition that is adapted of printing part and the offset press it is long
Spend the printed document of size.
Summary of the invention
The embodiment of the present invention is designed to provide a kind of inking damping device and rotary offset machine, using servo motor without
Axis actuation techniques can fast implement the stepless change application of rotating ratio between each ink roller and plate cylinder in rotary offset machine
On, make rotary offset machine when not needing replacement inking damping device, so that it may pass through quick-replaceable different-diameter size
Plate cylinder and blanket cylinder realize the printed document for printing a variety of different specification sizes, widen the printability model of rotary offset machine significantly
It encloses.

The fixing seat axle sleeve risen rotating around corresponding string roller is swung.In each swing rod swing process, between damping roller 28 and dampening vibrator roller 29 always
It keeps being steadily contacted, guarantees that the wetting moisture film amount on damping roller 28 is uniform and stable, same each inking roller (25,26,27) and corresponding
Also steady contact is remained between wavers 22, guarantees that quantity of ink on each inking roller (25,26,27) is uniform and stable etc..
When printing work, by operating the control button of each driving cylinder (56,57,58,59), Ke Yigai on manipulation screen
Become and control the airflow direction for flowing into compressed air in the cylinder, so that the expanding-contracting action of the cylinder piston rod be varied and controlled.
When cylinder 56,58 piston rod shrink and cylinder 57,59 piston rod elongation when, damping roller 28 and inking roller (25,26,27) pendulum
It is dynamic to be close to plate surface and to printing plate dampening inking；Conversely, the piston of piston rod elongation and cylinder 57,59 when cylinder 56,58
When bar is shunk, damping roller 28 and inking roller (25,26,27) be then swung away from plate surface round about, stop to printing plate
Water inking, that is, from water from ink.Since the piston rod collapsing length of each driving cylinder (56,57,60,64) can be in cylinder operation
Variation in stroke range, therefore, after plate cylinder 2 and blanket cylinder 3 that different-diameter size is replaced within the scope of certain size,
Do not need to carry out any adjustment, each inking roller (25,26,27) and damping roller 28 steadily can carry out inking to plate surface
Water or from ink from water etc..
The present embodiment has the advantage that
(1) so that rotary offset machine is provided with the function of printing a variety of different repeat length size printed documents, widen wheel significantly
Turn the printability range of offset press.
(2) when the printing of different repeat length sizes is printed in conversion, entire conversion process is simple to operate and quick,
Substantially increase the printing work efficiency of rotary offset machine.
(3) ink roller transmission uses the shaftless driving of servo motor and control technology, without between the inking device and plate cylinder 2
The gear drive for transmitting power, reduces the generation of printing gear black thick.
(4) 22 water-ink roller spread patterns are used, both ensure that inking damping device 1 had well stable workability
Can, while in turn ensuring printing black speed is fast at present, adapt to the high-quality and high speed printing requirement of rotary offset machine.
(5) clutch of copy roller (damping roller 28 and inking roller) uses cylinder drive control mode, and structure is simple, adaptability
By force.After replacing different-diameter printing cylinder, do not need to carry out any adjustment, the dampening of copy roller (damping roller 28 and inking roller)
Ink is reliable and stable from ink from water.
In the present embodiment, 22 ink roll rows are used based on the inking damping device 1 of interchangeable drum-type rotary offset machine
Column form guarantees that inking damping device 1 both has well stable working performance, and black speed is fast at present for printing, adapts to wheel
Turn the high-quality and high speed printing requirement of offset press.Wherein inking roller and damping roller 28 clutch of rising and falling be all made of cylinder driving and
Control mode, cylinder piston rod elongation and contractive action driving inking roller and damping roller swing rod 60 swing, make inking roller and
Damping roller 28 is close to plate cylinder 2 and automatically to plate surface dampening inking, or leaves plate cylinder 2 automatically i.e. from water from ink, by
It can change in cylinder operation stroke range in the piston rod collapsing length of each damping roller 28 and the driving cylinder of inking roller, because
This does not need to carry out any adjustment after printing cylinder for replacing different-diameter within the scope of certain size, each damping roller 28 and
Ink roller steadily can carry out dampening inking or from water from ink etc. to plate surface.
