Definitions

  • the invention relates to a doctor blade device, which consists of a plastic profile strip and a core strip made of steel or the like, which extends parallel to the longitudinal axis of the plastic profile strip and is embedded in the latter, the squeegee device being held on at least one holding arm and the core strip in Area of a squeegee (squeegee element) guided by the plastic profile strip is arranged.
  • a squeegee device can be pressed with its squeegee working edge or surface against a work surface (work surface) such as a table, a roller and possibly a material web lying thereon, a conveyor belt, a stencil and the like.
  • the devices are used in particular to apply substances to a work surface to be printed or coated.
  • a sheet-like support such as a web, a sheet of material, a roller or a belt by means of a stripping or sealing process.
  • the size of a desired substance space between the profile bar and the work surface in front of the doctor element or a desired contact angle of the doctor element on the work surface is determined or set by the inclination position of the profile bar, possibly by pivoting the doctor device and / or determining the swivel angle of the doctor device.
  • the invention has for its object to provide a doctor blade device with a core strip embedding profile strip, which is to be relieved of forces acting on the profile strip during its handling and / or operation and leading to undesirable deformations and which can be equipped with a roller or Round doctor blade should be particularly well suited.
  • the core bar forms a kind Backbone, the plastic profile strip embedding this particularly rigid core strip and, according to the invention, also connecting it with a doctor blade, a roller blade or a circular blade.
  • a roller or circular squeegee is enclosed in the "material flesh" of the profile strip. Since the core strip extends in the area of the squeegee, the enclosure, which partially encompasses the squeegee and holds it captively, is freed from deformations damaging the latter, even if the profile strip material consists of a particularly flexible, resilient polymer plastic that is particularly highly slidable to perform a squeegee function .
  • a swivel bearing which is preferably designed as a swivel-slide joint, lies within the opening, so it is countersunk in it, so that no swivel bearing parts protrude from the profile strip surface.
  • the holding arm can be designed in the form of a strip element with an extension parallel to the longitudinal axis of the doctor device.
  • a particularly stable hinge-like pivot connection is achieved when the arm is pivoted.
  • a special embodiment according to the invention consists in that the plastic profile strip with a holder of the squeegee device, which supports the holding arm, is positioned over a fixed final length freely shortenable element such as in particular a strip length provided with a certain length is connected in such a way that when the squeegee device is lifted from a work surface, a downward tilting / pivoting movement of the profile strip is limited by the then tight band.
  • a fixed final length freely shortenable element such as in particular a strip length provided with a certain length is connected in such a way that when the squeegee device is lifted from a work surface, a downward tilting / pivoting movement of the profile strip is limited by the then tight band.
  • this avoids that the profile bar, which is moved upward away from the work surface when the printing machine is at a standstill, tilts into the likewise raised, rotating template and damages it.
  • each squeegee device 1 comprises a one-piece profile strip 2 consisting of flexible and highly slidable plastic, which extends in a longitudinal view (not shown) over the working width a work surface 7 extends.
  • the profile strip 2 is provided with profile surfaces 22, 23, the size of a storage space or a gap for a through a in front of a doctor element in the form of a doctor blade 6, depending on the pivoting device pivoting position about an axis parallel to the longitudinal axis of the doctor device Form circular template 8 on the work surface 7 substance to be applied.
  • a core strip 4 of a material such as steel or the like which is rigid with respect to the plastic material is embedded in each plastic profile strip.
  • a continuous opening in the form of a slot 3 is incorporated between the upper surface 21 and the core strip 4, as can be seen in particular from FIGS. 3 and 4. In its longitudinal extent, the slots extend parallel to the core strip 4.
  • the holding arm part which extends outside the profiled strip 2 is at its free end provided with a swivel joint part in the form of a ball or a circular-cylindrical element, so that it can in particular be freely pivotably connected to a swivel bearing (not shown).
  • the holding arm can also be rigidly connected or connected to supporting parts such as a holding bar, a supporting bar or the like in a doctor device. The squeegee or profile bar is then in a fixed, unchangeable inclination position during squeegee operation.
  • the holding arm 5 is of strip-shaped design in cross section AB.
  • the arm thus consists of a flat element which extends in the strip cross section parallel to the core strip 4 and which extends through the slot 3.
  • the core strip 4 is rigidly connected to a joint element 31 which, in the cross-sectional illustration shown, extends in the slot 3, that is to say is arranged recessed therein.
  • the steel joint part 31 has a recess extending in the direction of passage of the slot 3, into which a circular cylindrical extension 32 of a holding arm 5 engages, so that the joint parts 31 and 32 form a swivel / slide joint 30 articulating the core bar 4.
  • the holding arm 5 is fixedly attached to a bearing or holding strip 50 arranged above the profiled strip 2.
  • a band 9 is attached to the tilting part of the profile strip 2 on its surface 21, which is fixed at its other end to the holder 50.
  • the foldable length of the band 9 is dimensioned such that the profiled strip 2 is held with the band 9 tightened when it is lifted from the work surface 7 or the template 8 in the pivoting / tilting position shown in FIG.
  • the core strip 4 is embedded in the profile strip 2 in the region of a roller doctor blade 6, ie the core strip 4 is arranged at a relatively short distance from the doctor blade element 6 in relation to the cross-sectional dimension of the profile strip 2.
  • Each squeegee 6 lies in a cross-sectionally circular recess extending parallel to the longitudinal axis of the squeegee device, which holds the roller squeegee 6 with its edges in a captive manner, the roller squeegee 6 freely rotating in the holding recess on the highly slidable plastic material of the profile strip 2 during squeegee operation.
  • the material of the profile strip 2 consists of a flexible, flexible and highly slidable polymeric plastic which is particularly resistant to abrasion and wear and is particularly chemically resistant.
