Description

The flexible contact of the reversal heliogravure application system that has outlet roller
Technical field
The present invention relates to heliogravure and apply, more particularly, the present invention relates to the flexible contact coating of reversal heliogravure that performance improves.
Background of invention
Be used to make continuous coated heliogravure coating and adopted a heliogravure roller, have depression or depression on the surface of this roller, they can control the thickness and the uniformity of coating.It is desirable to, fluid " is picked up out " each depression equably and is sent to substrate.Usually, described each depression is the pattern that is arranged to a kind of rule in the continuous regions coated of needs.The heliogravure that can adopt and design several types applies, so that strengthen transmitting coating material equably, and optimizing other coating response from the picking up of each depression or groove, and for example decay of the scraping of the surface lifetime of roller, substrate and pattern etc.
Fig. 1 shows the heliogravure coating unit of a direct type.Being coated with layer fluid 10 is from a square position 12 or other supply source, and for example an extrusion pressing type fluid bar is supplied to heliogravure roller 14.Be coated with that layer fluid 10 is adjusted blade by one or roller 16 is adjusted, and utilize substrate that an elastic bearing roller 20 makes band 18 and so on for example to contact and described fluid is sent on the substrate with fluid in each depression at a pressing place of point.Have the depression that burn into machined or annular knurl form on the surface of described heliogravure roller 14, these depressions can be Any shape or size, spread all over the surface of roller discontinuously or continuously.
The volume of these depressions is being controlled the average thickness of coating, and depression also is designed to have particular geometric shapes, so that strengthen the stability of picking up fluid in each depression.Accurately control the volume and the shape of these depressions, and can stably pick up the fluid of the component unanimity in these depressions, just can obtain to be better than the coating uniformity of other paint-on technique along the vertical and horizontal of band.Common interested physical characteristic is: the average thickness when coating is sent to band, uniformity, discontinuous (for example pin hole and striped) of appearance and relative smoothness, or the initial flatness of gravure roll sub pattern.
In a depression, take out sub-fraction fluid exactly so-called " picking up ".Three kinds of contingent stable modes of picking up are arranged, and have between the transitional type between them.Open coating is that fluid is transmitted in each depression individually, and does not have fluid to transmit between each depression.The formula that crosses is picked up in the material and the fluid junction in the adjacent depression that occurs in the depression, thereby forms a continuous coating when transmitting.Combined type picks up and occurs in when transmitting each pocket combination under situation together, the compound pattern that has been combined to form recess pattern or its part of described depression.
In various heliogravure application systems, there are some kinds to be used for controlling the control variables of picking up quantity and type.The volume of depression in bulk factor is meant on each unit are of heliogravure roller surfaces.When picking up the volume of constant quantity under the similar operation condition, above-mentioned bulk factor can be controlled the average thickness of wet coating.Overflow input quantity (flooded inlet) is meant the unnecessary Fluid Volume that remains there owing to their motion in band and roller convergence place.In case disperse generation film segregation phenomenon in the groove one as the roller exit on the sub-coating unit of a forward forming roll, natural unstabilizing liquid will produce the burr of machine direction in coating.When apply be a kind of gravure pattern rather than machine direction burr the time, frequency by making the gravure pattern and the natural liquid burr unstability frequency on machine direction are complementary, and just can strengthen the stability of picking up of each groove.The ratios affect of non-depression face/volume (land/volume) the type of picking up.One lower non-depression face/volume ratio formula that can cause crossing is picked up, and a higher ratio then can promote open coating.Helical angle is meant each groove in one three helical (trihelical pattern) pattern and the roll shaft angulation of heliogravure roller.The common helical angle of gravure roll sub pattern that can obtain on the market is 45 °.Less helical angle can promote the stability of picking up of forward heliogravure coating, and bigger helical angle can reduce to pick up the width of transitional region.Interior tooth angle is meant the angle between the relative depression wall.Cut Pingdu and be meant the flatness of depression bottom.
The tensioning modulus of the thickness of band, band, the hardness of backing roll and backing roll pressure all can influence average coating thickness, and this is because the effective volume factor of heliogravure roller can reduce owing to each depression of band infiltration heliogravure roller.The width that increases non-depression face can improve the wear-out life of heliogravure roller.The quantity that reduces the width of non-depression face and increase depression can be strengthened the decay of recess pattern when fluid is transferred into band, thereby promotes the smooth of flow surface.Velocity ratio is meant the ratio of the superficial velocity and the strip surface speed of heliogravure roller.Change velocity ratio and just can change coating layer thickness.
The groove pattern that heliogravure applies can influence the stability of picking up fluid in each depression.Look that in each variable of discussing minor variation also can allow the variation that can stablize the maximum coating speed generation hundreds of feet per minute clock that picks up, and can influence the ability of the wet coating that reaches extremely thin.
Along with the quickening of coating speed, reach stable, cross pick up the very difficulty that will become.When band when the heliogravure roller separates, the divided thin film that is commonly referred to as " vaporific " (from divided thin film from the fine droplet that splashes out) from the time unstability generally be to occur in coating speed increases.The haze method of phenomenon of a kind of inhibition is: reduce the speed of heliogravure roller with respect to band, and make it to work under the condition of a differential.Along with divided thin film from and the shearing force that puts on fluid can increase the work coating speed of the phenomenon that hazes before taking place.
Fig. 2 shows a kind of differential type heliogravure coating unit.14 one-tenth controlled contact conditions of band 18 and heliogravure roller are compared with the heliogravure coating of orientation high pressure, that do not have slip, and backing roll 20 has only slighter distortion relatively.Heliogravure roller 14 and elastic bearing roller 20 are drive.Have much between each variable in differential type heliogravure applies and influence each other.The work of the success under high speed, the pickup conditions that crosses is easy to and can be interfered because of some less variations of the variable of annular knurl design, application head or dispersion rheology (dispersion rheology).Can change coating layer thickness in the variation aspect adjustment and the velocity ratio.These variation meetings are because and influencing each other and reverse between other variable.
Fig. 3 shows a reversal heliogravure coating unit.The working condition of this heliogravure coating unit is similar to the differential coating unit, but the surface of heliogravure roller is to move along the direction opposite with band.Also have,, just can make 14 one-tenth controlled contact conditions of band 18 and heliogravure roller by elastic bearing roller 20 is carried out Position Control.Heliogravure roller 14 and backing roll 20 are drive.The superficial velocity of heliogravure roller can on the window of web velocities or under.Compare with other heliogravure coating unit, reversal heliogravure coating unit embodies one and is used to the bigger action pane accepting to apply.
Fig. 4 shows the flexible contact of a kind of heliogravure (gravure kiss) coating unit.Because heliogravure roller 14 can rotate, so do not show the supply and the adjustment of fluid two-wayly.The working condition of this heliogravure coating unit is similar to a reversal heliogravure coating unit, but, band 18 is contacted with heliogravure roller 14 by an input idler roller 22 and output idler roller 24 being set on heliogravure coating unit 14, to produce a slight stretch-draw.The superficial velocity of heliogravure roller 14 can on the speed of band 18 or under.Adopt other pattern heliogravure mode can not make fluid when transmitting, always make the recess pattern attenuation, but under suitable depression design and fluid rheology condition, adopt this kind technology to accomplish.
In the flexible contact of reversal gravure applies, band 18 with one freely span by between the idler roller 22,24.A relatively long span is arranged between the close idler roller 22,24 of heliogravure roller.This span can be 30cm, and described heliogravure roller 14 centrally is positioned between the idler roller 22,24.When band was applied, this relatively long span can allow transmitting the band fluctuation of generation high frequency on the contact point.Also have, the tension force of band can cause producing wrinkle on the strip width direction, thereby makes the thickness generation deviation of strip width direction, and these deviations will be revealed as along the band marking longitudinally.
Fig. 5 shows a kind of compensation heliogravure coating unit.Compensating roller 26 in the middle of between elastic bearing roller 20 and heliogravure roller 14, being provided with one.Heliogravure roller and compensating roller can two-wayly rotate, thereby produce transmission forward or backwards.This coating unit normally is used for extremely thin coating.The velocity ratio of band 18 and heliogravure roller 14 can be up to 10: 1.Compensating roller 26 must be made by elastomeric material, enters into the interior fluid that also therefrom picks up of depression of heliogravure roller so that it can be out of shape.Variable effect on the transmission point between heliogravure roller 14 and the compensating roller 26 is similar to other heliogravure coating unit.Usually, to the velocity ratio of the transmission of band near 1: 1, and from the transmission of compensating roller 26 pattern of attenuate heliogravure roller greatly.

Describe in detail
The flexible contact of reversal heliogravure of the present invention application system can be coated to a fluid coating material 10 on the substrate of band 18 and so on for example.Band has a coating surface 28 that is coated with coating material 10 on it, and a rear surface 30 on the other side.Any substrate that can utilize flexible contact to apply all can utilize this system to be applied.Can make a kind of product of this application system operational excellence is magnetic medium, and it applies a wet coating of being made up of adhesive and magnetic-particle and forms on a band.
This application system comprises roller or other device (not shown), applies station in order to transmit the band turnover, and described band is applied on the coating station.Referring to Fig. 6, band at first by an input idler roller 22, then enters heliogravure roller 14 again.Idler roller 22 can be made by rubber, carbon fiber composite, steel, aluminium or other material.
Heliogravure roller 14 is to rotate along the direction opposite with the band direct of travel, and the fluid coatings material 10 that will be stored in each annular knurl groove of heliogravure pattern deposits on the coating surface 18 of band 18.Coating material 10 can deposit in each annular knurl groove by any way, for example allows heliogravure roller 14 rotation and by a square position 12 that fills coating material 10.Heliogravure roller 14 can contact on the span one freely with band 18, with heliogravure roller 14 and band 18 between the rear surface 30 of the relative band 18 of contact wire on need not any supporting.As shown in the figure, the center of idler roller 22 is above the heart among the heliogravure roller 14.
Driven, bigger, an accurate outlet roller 32 is positioned at the downstream of heliogravure roller 14, and described outlet roller can be the steel rider of a polishing.Outlet roller 32 is driven by for example device of motor and so on the direction identical with band 18 and is independent of band through it.As shown in the figure, the center of idler roller 22 is below the heart among the outlet roller 32.The diameter of outlet roller 32 can be about 12-16cm, and this has surpassed idler roller 22 widely.When band 18 contacts with heliogravure roller 14 and after coated material 10 applied, it was wound on as one and takes out on the outlet roller 32 of roller.
Contact point and band 18 at heliogravure roller 14 and band 18 have short span between the coiling contact point of outlet roller 32.This distance can be less than 1cm, in some cases can be less than 0.075cm.Dynamic moistening line appears in the shorter span between heliogravure roller 14 and the outlet roller 32.So just having guaranteed has bigger stability in the process that coating material is sent to band, and makes band keep not moving on the direction of non-vertically (non-downweb).So just can eliminate the vibration of band and play bag phenomenon (bag), and prevent that moistening line from pulsation taking place and cause measured deviation, these are known as chatter (chatter).Contact coating with the traditional flexibility that adopts the heliogravure roller and compare, can also on the vertical and horizontal of band, obtain the good uniformity like this.
As shown in the figure, outlet roller 32 can be in the top of heliogravure roller 14.Band 18 can be with an angular movement that makes progress between heliogravure roller 14 and outlet roller 32.Gravity is inoperative, and whole system can be orientated in any direction along with moving of band, even it is good to reverse.
Contact application system with general flexibility and compare, this application system has a band span that reduces between heliogravure roller 14 and immediate upstream idler roller 22, and a band span that reduces is greatly arranged between heliogravure roller 14 and outlet roller 32.Because the flexibility contact that begins from the contact point between band 18 and the outlet roller 32 transmits point less than 2.5cm, so the fluctuating range of band is less.Because outlet roller 32 has stable supporting and has accurate structure, so do not find the phenomenon of band vibration.So in fact can band vertically on produce uniform coating.When producing floppy disc, can reduce the adjustment of floppy disc like this, and strengthen the performance of online image detection system.Similarly, the coating uniformity also is very important in other a lot of occasions, for example the very important occasion of the transparency of those light (no matter being to measure objectively or subjectively measure with human eye).
In the embodiment shown in fig. 7, the strap tension of application system upstream (input band) can be isolated with the strap tension of this application system downstream (output band).One can be in the new band 18 of press bonding roller 34 pressing between outlet roller 32 and itself of idler roller 22 upstreams.This pressing can produce a pressure differential in the front and back with outlet roller 32 pressing contact points.One higher tension force can be positioned at the upstream of press bonding roller 34, or the downstream of press bonding roller 34.
