Abstract
The present invention relates to a kind of ink fountains of printing machine comprising scraper and the clamping lath (4) for clamping scraper.Lath (4) are clamped to be made of middleware (6) and end piece (7).
Description
Technical field
The present invention relates to a kind of ink fountain of printing machine, which includes scraper and the clamping lath for clamping scraper.
Background technique
Such ink fountain describes in 10 2,015 207 719A1 of document DE.In this ink fountain of the prior art, folder
Tight lath manufactures the bent plate part at pectination profile in the form of only one part.Clamping lath includes one group of lever arm, these thick sticks
Lever arm forms arrangement.Lever arm construction positioned at the end of the arrangement is wider at remaining lever arm than the arrangement.This point
Section and the side wall sealing element of storage container are mutually coordinated.Clamping lath can be made of elastic plate.It is indicated herein to be, with clamping
Strip shaped tectonic is compared at the case where aluminium drawing part, in the case where clamping lath is configured to bent plate part by elastic plate, is not present
It is following dangerous: that is, clamping lath due to load and as the time deforms in an irreversible fashion.This irreversible deformation is furthermore
Result in the reduction of clamping force.
In the prior art disadvantageously, lath is clamped to be difficult to clean due to its pectination profile.
Summary of the invention
The present invention is based on following tasks: realize it is a kind of with can easy cleaning clamping lath ink fountain.
The task is addressed by the ink fountain with feature described in claim 1.Printing machine ink fountain according to the invention
Clamping lath including scraper and for clamping scraper, which is characterized in that clamp lath and be made of middleware and end piece.
The advantages of ink fountain according to the invention, is that the clamping lath of the ink fountain is can be more easily clean.The clamping plate
Item need not have pectination profile, also, instead, can have simpler profile, which can be easy to clean.
Attendant advantages are, although can easy cleaning, there is no following dangerous, that is, clamps lath since it is negative
Carry and as the time can exceedingly deform.The reduction of clamping force caused by this deformation is avoided.
Different improvement projects is possible.
Preferably, compared to middleware, these end pieces are more stably constituted in terms of deformation.Here, these end pieces
There can be different (such as thicker) profiles compared with middleware, and/or include the material different from middleware.For example,
Middleware can be made of aluminum or aluminum alloy, and end piece can be made of steel or titanium.These end pieces can be with middleware
It is attached by pin fixed part (Verstiftungen) or similar connecting element.This pin fixed part can for example lead to
It crosses pin or preferred holding pin is constituted.These end pieces can be connected with middleware by adhesive portion, which can be with
It is arranged with being additional to or be alternatively to pin fixed part.
Detailed description of the invention
Alternatively improved scheme is generated by being described below with affiliated attached drawing, and attached drawing is shown:
Fig. 1: ink fountain；
Fig. 2: the details of the clamping lath of ink fountain；
Fig. 3: the middleware of lath and the exploded view of end piece are clamped；
Fig. 4: middleware and end piece under assembled state；And
Fig. 5: the remodeling of lath is clamped.
Specific embodiment
Fig. 1 shows the component of the anilox roll ink architecture of the printing machine of offset printing.Shown be anilox roll 1 and have scrape
The ink fountain 2 of knife 3, the scraper 3 rest in anilox roll 1.Anilox roll 1 is only indicated with imaginary line, and only shows ink fountain 2
Part.It has extended parallel to clamp lath 4 with scraper 3, for scraper 3 to be clamped in ink fountain.Lath 4 is clamped to be configured to put
Bar, and manipulated when clamping by eccentric shaft 5.The lever arm for clamping lath 4 rests on eccentric shaft 5, and another lever
Arm is pressed on scraper 3.
Fig. 2 shows clamping lath 4 includes two end pieces 7 and therebetween middleware 6.Middleware 6 and anilox roll 1
Rotation axis in parallel (according to visual direction BR observe) be arranged between the two end pieces 7.These end pieces 7 respectively with ink fountain
2 side wall sealing element 10 is aligned, this is visible in Fig. 1.These end pieces 7 are fixedly connected with middleware 6, also, with middleware 6
Material compare, these end pieces 7 include more stable material in terms of deformation, and the elasticity modulus of the material is bigger.Middleware 6
It is made of aluminum and be pultrusion part.These end pieces 7 are made of titanium or preferably made of steel, and are milling parts.
Fig. 3 is shown, and middleware 6 and corresponding end piece 7 can have identical profile.The profile have clamping face 11,
Hinged hook 12 and protrusion 13.Clamping face 11 rests on scraper 3 when clamping.The end of hinged hook 12, which is formed, tumbles a little, folder
Tight lath 4 is when clamping around the spot wobble of tumbling.Protrusion 13 forms profile thickened section, introduces in the profile thickened section
There is the hole 9 for a holding pin 8.Other holes 9 for other holding pins 8 are introduced into hinged hook 12.
Fig. 4 is shown, and corresponding end piece 7 is connect with middleware 6 with pin fixed form.Each holding pin 8 is inserted in centre
In hole 9 in part 6 and at the same time in the hole 9 being inserted in end piece 7.In order to can with it is better seen that this point, end piece 7 with
Show to imaginary line perspective.Holding pin 8 is configured to the pipe in wall with longitudinal slot, and holding pin 8 is inserted into hole 9 at it
In after opened in a manner of springing.If the clamping action of holding pin 8 does not keep these slat elements 6,7 fixedly enough
Together, then these end pieces 7 can be additionally be bonded with middleware 6.For example, holding pin 8 can be with these slat elements 6,7
Bonding.
The visual direction BR that Fig. 5 is indicated from Fig. 2 shows the remodeling for clamping lath 4.The difference of the remodeling and previous embodiment is only
Be only that: the profile of these end pieces 7 is narrower than the profile of middleware 6.These end pieces 7 have width of sheet LB7, and the lath is wide
Spend the width of sheet LB6 that LB7 is less than middleware 6.Difference between LB6 and LB7 forms corresponding end piece 7 and middleware 6
Ladder between side.That profile (right side in Fig. 5) backwards to hinged hook 12 of end piece 7 is with middleware 6 backwards to hinge
That profile for connecing hook 12 equidistantly extends, and those of hinged hook 12 of these slat elements 6,7 double team profile is (left in Fig. 5
Side) extend consistent with each otherly.Since these end pieces 7 have more stable or more rigid material, these end pieces 7
The clamping force compared to the higher clamping force of middleware 6 or at least same size can be applied in remodeling, and herein not than
Middleware 6 more strongly deforms.
Above-mentioned two embodiment is suitble to, by clamping lath 4 in high load area (especially side wall sealing element
Region) in by means of attachment element (especially: end piece 7) preferably by more portative material carry out local strengthening, this is reliably
Ink is prevented to leak from ink fountain 2.(referring to Fig. 1) in the region of these side wall sealing elements 10, ink fountain 2 is in no countermeasure
In the case where can be easy to leak.
Ink fountain 2 shown in FIG. 1 has only unique scraper 3.However there is also such ink fountain, which has two
The scraper of a clamping on it；Such ink fountain is referred to as chambered doctor blade.In the case where ink fountain is configured to chambered doctor blade, it is equipped with
Two clamping laths according to the invention.Ink fountain is not considered only as the ink fountain of off-set oil ink, and is also understood as printing
The ink fountain of primary coat (such as zinc white), printing gloss varnish (such as varnish) or other printable fluids.
