Abstract
The present invention relates to a kind of scraper devices for printing machine comprising the clamping bar for clamping scraper.The clamping bar forms the profile of comb shape.
Description
Technical field
The present invention relates to a kind of scraper devices for printing machine comprising matrix, scraper, pressure part and for clamp scrape
The clamping bar of knife.
Background technology
This device is shown in Figure 10 a and 10b in 1 196 287 B1 of EP.
Invention content
It is an object of the present invention to propose a kind of other scraper device.
The purpose is realized by the scraper device with feature of the present invention.
Scraper device according to the present invention for printing machine includes matrix, scraper, pressure part and for clamping scraper
Clamping bar, wherein clamping bar forms the profile of comb shape.
The advantages of scraper device according to the present invention is that clamping bar can be manufactured into bent plate with a unique component
Part.
In a further scheme, clamping bar includes the first lever arm, multiple second lever arms and multiple third lever arms,
In, when clamping, the first lever arm sticks on scraper, and the second lever arm sticks on pressure part, and third lever arm energy flip-flop movement
Ground is supported on matrix.Herein that is, clamping bar has one group of second lever arm and one group of third lever arm and at least one the
Unique first lever arm of one lever arm, i.e. or multiple first lever arms, i.e. one group of first lever arm.
In a further scheme, the second lever arm forms the first comb, and third lever arm forms the second comb,
And the second lever arm and third lever arm are alternately arranged.Therefore, the second lever arm and third lever arm are arranged on gap.
In a further scheme, the second lever arm forms a row, and in the row, is located at the second external lever arm
It is wider than positioned at the second lever arm between them.Middle part of the second lever arm being arranged on the end of the row than being arranged in the row
In the second lever arm it is wide.
In a further scheme, the first lever arm forms the first hook with outer seamed edge, the outer rib on its end
While being sticked on scraper when clamping.First hook is bent with extending far from scraper.
In a further scheme, third lever arm forms multiple second hooks, and the first hook and second hook in the same direction, example
As being deasil bent.By the same view, the first hook and second hook are directed toward identical direction of rotation.
In a further scheme, there is the first lever arm groove, the groove to extend along the longitudinal direction of clamping bar.
That is, the longitudinal direction of groove is parallel with the longitudinal direction of the longitudinal direction of scraper and pressure part.
In a further scheme, clamping bar includes spring leaf.The further scheme in high functional safety and
It is advantageous in terms of service life.Be configured to aluminium tensioning member clamping bar on the contrary, curved being configured to be made of spring leaf
In the case of plate, there is no the danger that clamping bar is become irreversibly deformed due to load with the time.Otherwise, this irreversible
Deformation cause clamping force to reduce.
In a further scheme, matrix forms the storage container for ink or gloss varnish.It is stored in storage container
New ink or new gloss varnish.The container is not intended to the reception container of contaminated ink or contaminated gloss varnish.
In a further scheme, pressure part is eccentric shaft.Eccentric shaft is the eccentric rod revolvably supported, transversal
Facial contour forms a kind of controlling curve.Cross-sectional profiles can be scabbled with polygon or elliptical shape or with band circumference
The shape of the circle in portion, as illustrated by the following embodiments.
Description of the drawings
Advantageous further scheme is obtained by the explanation of embodiment and affiliated attached drawing.
In attached drawing：
Fig. 1 shows the scraper type ink fountain of anilox printing unit,
Clamping bars of the Fig. 2 to illustrate scraper type ink fountain as the amplification of thin portion,
Fig. 3 illustrates clamping bar with three-dimensional, and
Fig. 4 shows the side view of the section of clamping bar.
Specific implementation mode
Printing machine 2 for offset lithography includes anilox inking unit, and the anilox inking unit has anilox roll
(do not draw and show) and corresponding scraper device 1.Scraper device 1 has the matrix 3 of the bottom with arc-shaped bend.Rear wall energy edge
The boundary that bottom deflection ground was supported and limited jointly with the bottom storage container 18, ink containment is held in the storage
In device.Ink is conveyed to anilox roll by scraper device 1, wherein scraper 4 sticks in anilox roll and removes from the anilox roll
Extra ink.
Scraper 4 is arranged between matrix 3 and clamping bar 6.Clamping bar 6 can be manipulated and adjusted by means of pressure part 5, so as to
It clamps scraper 4 and releases clamping again.Pressure part 5 is revolvably supported and is configured to eccentric shaft.
Clamping bar 6 is seesaw and includes first lever arm 7 with clamping face, and the clamping face paste leans against on scraper 4.This
Outside, clamping bar 6 includes one group of second lever arm, 8,8.1,8.2 and one groups of third lever arms 9.Second lever arm 8,8.1,8.2 is the first comb
The component part of shape part 10, and third lever arm 9 is the component part of the second comb 11.Each second lever arm 8,8.1,8.2
With an other gap alignment of the second comb 11, and one of each third lever arm 9 and the first comb 10 is in addition
Gap alignment.Second lever arm 8,8.1,8.2 is alternately arranged with third lever arm 9.
Second lever arm 8,8.1,8.2 constitutes a row 12.As illustrated in fig. 3, second be located on the end of the row 12
Lever arm 8.1 is wider than remaining second lever arm 8.2.The division and the side wall sealing of storage container 18 match.
Clamping bar 6 is the bent plate part to consist of spring steel, and is detached by being processed between second and third lever arm 8,9
Line and then third lever arm 9 is bent outwardly from the row 12 to manufacture comb 10,11.It can be by means of laser cutting institute
State defiber.
As illustrated in fig. 2, the cross section of clamping bar 6 is repeatedly bent.The first hook 13 with outer seamed edge 14 is located at first
On the end of lever arm 7, the outer seamed edge 14 constitutes the already described clamping face of the first lever arm 7.
Each third lever arm 9 constructs second hook 15 on its end.Clamping bar 6 is so-called in composition by this group of second hook 15
Overturning joint in the case of be supported on matrix 3, wherein after second hook 15 be engaged matrix 3 same hook-shaped protrusion.Such as
As shown in Figure 1, pressure part 5 is arranged close to the protrusion, to ensure that clamping bar 6 is hooked with matrix 3.
As illustrated in fig. 4, fluted 16 are processed in order to make the first lever arm stablize, in the first lever arm 7, the groove along
The longitudinal direction 17 of clamping bar 6 extends.
