The sealing device all be favourable in all fields according to configuration of the present invention: even crooked thin slice also guarantees definitely to seal reliably the gap between rear wall and the fountain bottom under the high fluid dynamic pressure that reaches 1 crust of printing-ink.What should be regarded as attendant advantages is, when rear wall when doctor is swung, this crooked thin slice plays the effect of cleaning doctor and printing-ink is wiped from fountain bottom.The part that open wide in printing work, that be positioned at a side opposite with printing-ink of swing rear wall of fountain bottom has been exempted fully in principle by the scraping effect of thin slice and has been printed ink pollution.
Advantageously, the sealing device is swung on rear wall at this by firm grip.
Advantageously, this scraping ink knife type ink fountain has a recessed bottom, and the sealing device rests on this bottom.
Advantageously, this swing rear wall can swingingly be supported around a hinge, and this hinge is arranged on this top, bottom.
Advantageously, the sealing device construction becomes the laminar edge of an inserts of this scraping ink knife type ink fountain.
Description of drawings
In further technical scheme, describe and obtain to preferred embodiment and the description of the drawings according to the favourable expanded configuration of scraping ink knife type ink fountain of the present invention from following.Accompanying drawing is represented:
Cable roll of Fig. 1 and a scraping ink knife type ink fountain from this cable roll tripping,
Fig. 2 cable roll and the combined pressure scraping ink knife type ink fountain on this cable roll, and
One of Fig. 3 is used for the ink fountain inserts of scraping ink knife type ink fountain.
The specific embodiment
The bottom 5 of ink fountain 2 or constitute by the surface of matrix 4 or by the film that is positioned on the matrix 4.Bottom 5 can be configured to anti-adhesive, promptly has the surface characteristic of repelling printing-ink 9.Hinge 7 is positioned at 5 tops, bottom and constitutes the central point of the circular-arc curvature of recessed bottom 5.
Have a gap between the lower limb of rear wall 6 and bottom 5, the width in this gap keeps constant and is about 0.5 millimeter around hinge at rear wall 6 between 7 moving periods.On the bottom of rear wall 6, be provided with a sealing device 10 towards a side of doctor 3 at this rear wall.Sealing device 10 is thin slices, the banded ground of this thin slice longitudinal extension on the direction vertical with respect to the diagram plane of Fig. 1 and Fig. 2.Sealing device 10 is by PET (PETG) or have similar high mar proof and other plastics formation of elastic-like.The PET film that is preferred for making sealing device 10 is more inexpensive.Sealing device 10 have about 0.2 millimeter thickness and by firm grip on rear wall 6.
Preferably sealing device 10 is clamped between wide part 8 of the flow model that can be threaded on the rear wall 6 and the rear wall 6.Thus, sealing device 10 is fixed on the rear wall 6 with being easy to dismounting, and thus, sealing device 10 can be changed when its wearing and tearing or damage not too bothersomely.
Before rear wall 6 and matrix 4 assemblings, also bending and sealing device 10 do not stretch out above the following seamed edge of rear wall 6 about 1 to 2 millimeter to sealing device 10.Sealing device 10 is determined size thus like this, makes that when rear wall 6 was assembled with matrix 4, sealing device 10 leaned on bottom 5 and be flexibly crooked in the case.Rear wall 6 assemble like this with matrix 4, make sealing device 10 because it leans on bottom 5 towards doctor 3, i.e. bending to the right with regard to Fig. 1 and Fig. 2.This for example can be by in the opposite direction, promptly small left sliding motion causes with regard to Fig. 1 and Fig. 2.After rear wall 6 was encased in the ink fountain 2, therefore direction bending and the sealing device 10 towards the printing-ink apotheca of ink fountain 2 be pressed on the bottom 5 with certain crooked prestressing force because it exceeds width for sealing device 10.
This ink fountain 2 is worked as follows:
Expression occurs in printing work state before among Fig. 1, and in this state, printing-ink has been filled in the ink fountain 2.At this, move away doctor 3 to rear wall 6 this degree, make the printing ink liquid level of printing-ink 9 be positioned at also not by combined pressure below the blade of the doctor on the cable roll 13.Thus, printing-ink 9 can not flow to more than the blade and can not flow out from ink fountain 2.In first step, ink fountain 2 combined pressures are on cable roll 1, and thus, the blade of doctor 3 contacts with the circumferential surface of cable roll 1.In second step, rear wall 6 is towards cable roll 1 and doctor 3 swings, and wherein, printing-ink 9 major parts are come out by extruding from matrix 4.When rear wall 6 was swung like this, sealing device 10 was inswept on bottom 5, and in the case, this bottom is swiped very totally.In addition, because described swing, the printing ink liquid level of printing-ink 9 is raised by this degree ground, makes the printing ink liquid level be positioned at from now on above the blade of doctor 3.
Make then cable roll 1 in Fig. 2 with rotating on the direction of rotation shown in the arrow.Because this rotation of cable roll 1 in printing work, the printing-ink 9 between rear wall 6 and cable roll 1 forms the printing ink vortex, and this printing ink vortex is also referred to as the printing ink volume and represents with arrow in Fig. 2.Because the motion of printing-ink 9, this printing-ink will be applied on the sealing device 10 than higher fluid dynamic pressure.Point to deposit printing ink owing to be configured to the bending direction of the sealing device 10 of the promptly thin flexible sealing lip of thin slice, this pressure is bigger, bottom the sealing device just more is pressed in tightly by described fluid dynamic pressure on 5.Thus, because the sweep of selecting according to the present invention orientation of sealing device 10, described otherwise mean that the high fluid dynamic pressure of spillage risk has strengthened the sealing function of sealing device in an advantageous manner.
Fig. 3 represents a flexible program, in this deformation program, thin slice, is the lower limb that sealing device 10 constitutes the inserts 11 in the ink fountains 2.This inserts 11 is made up of film, and this film is for example made of plastic, and this film is crooked like this, the sidewall 12 that makes inserts 11 have to be used for lateral seal.Inserts 11 adapts to the shape of rear wall 6 and the wide part 8 of flow model, and this inserts is housed on described rear wall and the wide part of flow model, pollutes so that protect these structural members to avoid printing-ink 9.
