Definitions
- Roller scraper on framework for applying coatings to material webs
- the invention relates to a roller scraper applicator for direct or indirect application of coatings to material webs with a doctor rod rotatably mounted in a holder, resting on the material web or on a roller guiding the material web.
- Roll scraper applicators of this type serve this purpose. Apply primer and top coats directly or indirectly to cardboard and paper.
- Other, non-pigmented application media for example for surface cleaning. for coating or pretreating technical papers and films are possible.
- Dry application weights from 0.5 to 20 g / m with the smoothest possible surface, i.e. with a good cross profile without streaking.
- the thickness of the coating results from a balance of forces between the elastic pressure and the hydrodynamic liquid pressure of the maximras that arises in the wedge-shaped gap between the material web or the roller guiding the material web and the doctor rod.
- Rotatable doctor rods made of solid steel are known and described in DE-PS 30 22 955. They are well suited for the metered application of pigment coats on paper, so that a desired one
- doctor blades are less suitable. if a pigmented application medium is to be applied indirectly first to a rubberized roller or directly to a very smooth, closed web surface, for example a film.
- the hydrodynamic fluid pressure is often so low that the contact pressure cannot be reduced as much as would be necessary without unevenness in the transverse profile, i.e. Streaks with lower and higher order result.
- the object of the invention is to improve the roller scraper applicator in such a way that there is a wide coat weight range with a good cross profile on different web materials and with a wide variety of coating materials.
- the doctor rod consists of a core and a sheathing with different elastic modulus.
- Doctor rod made of solid material in relation to the pressure Reduce relatively high rigidity, so that the doctor rod lies evenly on the material web or aligns the surface of a counter roller.
- the doctor rod according to the invention consisting of a core and a jacket with different elastic modulus is based on the knowledge that a reduction in the doctor rod diameter alone reduces its rigidity, but does not provide a solution to the problem, since with the reduction in the doctor rod diameter also the hydrodynamic liquid pressure due to the geometric change in the dosing zone, ie with the associated increase in the wedge angle, drops faster than the stiffness of the doctor rod decreases. Conversely, increasing the doctor rod diameter increases the hydrodynamic fluid pressure in the metering zone, but the fluid pressure increases more slowly than the stiffness of the doctor rod increases with increasing diameter.
- the modulus of elasticity of the sheathing is preferably smaller than that of the core, which can advantageously be achieved in that the sheathing is made of plastic, for example PTFE or PVC, and the core is made of steel.
- the core absorbs the torsional stress occurring in the doctor rod. while the flexible plastic coating brings the outside diameter to the value that is required for optimal coating.
- the diameter of the steel core is preferably 6 to 10 mm and the outer diameter of the plastic sheathing is 10 to 20 mm.
- the surface of the core can be structured to prevent the plastic jacket from shifting or slipping relative to the steel core. eg out of round and the example complementary inner surface of the casing to be positively connected to the surface "of the core.
- a thin-walled, wear-resistant casing can be placed around the casing, which consists of an approximately 0.3 mm thick steel casing.
- This embodiment is used in particular for the direct coating of paper webs, since increased wear of the elastic sheathing occurs in this application.
- the squeegee rod is driven, preferably in the opposite direction to the counter-roller movement or to the material web movement, and is mounted in the holder by means of a squeegee bed from a compressed air hose, so that the contact pressure can be changed by changing the compressed air pressure on the hose.
- the drawing serves to explain the invention using two exemplary embodiments.
- the drawing shows:
- Fig. 1 cutout a roller scraper for direct coating of a paper web which is guided around a counter roller.
- the coating material is applied directly to a material web.
- a counter roller 1 of which only one segment is shown. runs a material web 2 and is provided with a coating 3 predetermined square meter weight.
- excess coating material is removed by means of a doctor rod 5 rotatably mounted in a holder 4.
- This doctor rod 5 is driven counter to the direction of movement of the counter-roller 1 indicated by an arrow and displaces the unnecessary coating material downwards, where it drips into a tub (not shown).
- the doctor rod 5 consists of a core 6 made of steel, on which the driving torque acts.
- the core 6 is with a sheath 7 made of plastic, for example PTFE or PVC. provided and additionally has a wear-resistant shell 8, which in turn consists of steel. This wear-resistant sleeve 8 is required when the coating material and the material web 2 lead to increased abrasion of the doctor rod 5.
- the doctor rod 5 is held in a doctor bed 9, which consists of a rubber hose with compressed air and a hollow chamber 10.
- Air pressure in the hollow chamber 10 the contact pressure of the material web 2 and the coating material can be adjusted so that the line application has a perfect surface and its weight per square meter can be varied within wide limits.
- E x I 0.85 x 10 N / mm only twice; it is still significantly below the bending resistance of a doctor rod of the same diameter made of solid steel.
- the coating 3 is applied indirectly.
- the material web 2 is only brought up to the roller when the coating 3 is applied in the manner described in a metered manner to the roller surface instead of to the material web.
- the coating is then taken over by the material web which is brought up and around the roller 1.
- the counter-rollers 1 Since the counter-rollers 1 have a rubber or rubber jacket, hardly any abrasion occurs on the doctor rods 5. These therefore do not require a wear-resistant casing. Their construction corresponds to the doctor rod shown in FIG. 1, with the wear-resistant casing 8 missing. The casing 7 of the doctor rods 5 is thus on the counter-rollers 1.
- a roller applicator 11 with an ink pan 12 and an applicator roller 13 is used in both embodiments 1 ( Figure 2). Dosing to the desired coat weight is then carried out using the roller scrapers 5 according to the invention.
