Definitions

  • the invention relates to a doctor blade holder, in particular in a coating device for coating a material web, with which a doctor element can be releasably held.
  • the doctor element may be designed as a stiff blade set at a predetermined fixed angle to the surface to be coated; the squeegee element can also be designed as a so-called soft blade, which is set at a particularly acute angle with respect to the surface to be doctored off.
  • the doctor element can be a doctor element with a rotating rod with or without grooves.
  • the invention relates to a doctor blade holder with which such a doctor element is used in a device for painting or coating a material web, for painting or coating plate-shaped elements.
  • the doctor blade holder can also be used in coating devices in which transfer rollers or belts are first coated, in order then to transfer the coating material to the material web or the plate-shaped elements.
  • the doctor element may be configured to cooperate with the web or rolls or belts.
  • the coating material is referred to as a coating color, this name stands for and includes coating colors, adhesives, paints, lacquer impregnating agents or the like.
  • One area of application of the doctor blade holder according to the invention is in a coating device for painting paper or cardboard, which is guided in webs by the coating device.
  • the coating device With the coating device becomes coating color applied the material web.
  • the coating color can be applied directly to the supported by a roll or a belt web and then spread with a doctor element (scraped), or the coating color is applied to the required thickness on a transfer roller, from which the coating color then transferred to the web becomes. It is also possible that the coating color is applied to the web by means of a transfer roller and adjusted there to the desired layer thickness with the aid of the doctor element.
  • Squeegee holders are known from the prior art, which have a sliding in a carrier slider with a holding jaw, which cooperates with a fixed, attached to the carrier or formed fixed holding jaw. Squeegee holders are necessarily exposed to the coating color and are polluted by this. According to the prior art, drain openings are provided in the slide and / or the carrier, can run through the coating color or detergent when cleaning the doctor blade holder.
  • the present invention seeks to propose a blade holder, which is insensitive to contamination.
  • a doctor blade holder in particular for a coating device for coating a material web, such as a paper or board web, is proposed, the holding jaws, which can hold a squeegee between them, wherein the holding jaws are guided by at least one flexible element relative to each other and movable under deformation of the at least one flexible element relative to each other.
  • the solution according to the invention is a technically simple solution and is therefore robust and inexpensive.
  • flexible elements a variety of elements can be used, it can be plate-shaped, rod-shaped or block-shaped elements.
  • the flexible element may be elastic, so be resilient, but it may also be a pliable element that is deformable without the generation of restoring forces;
  • a fabric-like structure can be used.
  • the flexible element may also be a component which consists of resilient individual parts and rigid individual parts.
  • the flexible element may be a spring element with a rigid plate, which is provided on one or both sides with elastically connected to the plate edge strips on which the spring element is held.

Corrosion resistant materials like CfK and GfK are cheap and durable.
  • the doctor blade holder has at least one actuating element, with which the holding jaws are movable relative to each other.
  • the actuator may be used to open or close the retaining jaws.
  • the doctor blade holder is designed so that at least one spring element is installed, which biases the holding jaws in an open position. In this way it is ensured that when switching off a non-self-locking actuating element, the holding jaws are opened and the doctor element is released.
  • the squeegee holder is constructed so that during maintenance operations (maintenance position) the squeegee holder is not dependent on external power supply (no external power supply is used to hold the squeegee holder in the open position) thereby avoiding hazardous situations; accidental entrapment of body parts or clothing is prevented. If a self-locking actuator, which remains in the assumed position even without power supply, is used, energy can be saved.
  • the doctor blade holder may be configured so that a spring element biases the holding jaws in a closed position. This can prevent the squeegee element from being accidentally released when the power supply to a coater is cut off. With an appropriate design of the spring element, it is conceivable that energy can be saved in this way during operation of the coating device, since the state in which the doctor element is held, requires no constant power supply.
  • the at least one flexible element is attached to at least one of the holding jaws and guides the movement of the holding jaw.
  • the at least one of the holding jaws may be held on an end portion of a single flexible element and perform a pivoting movement under deformation of the flexible element.

As a length, the dimension or extent of the leaf spring is referred to, which lies in a (curved) plane in which the bending line of the leaf spring is located, while the perpendicular extent of the leaf spring is referred to as the width thereof.
  • the one or more spring elements may be pre-bent with a certain shape; but they can also be straight.
  • the doctor blade holder has a support to which the at least one flexible element or elements are or is attached, and which has a stop serving as a fixed holding jaw, which cooperates with at least one movable holding jaw.
  • the at least one movable holding jaw is attached to one end of a single leaf spring and the other end of the leaf spring is fixed to the carrier, so that the leaf spring is bent under actuation by the actuating element and thereby pivots the movable holding jaw against the fixed holding jaw.
  • the pivoting movement does not have to be a complete pivotal movement, such as that obtained when a bar is pivoted about a pivot point.
  • pivoting movement used here expressly includes those deviating from a pure pivoting movements.

  • the holding jaws and / or the flexible elements can be mounted as side by side in the cross-machine direction of the carrier. Smaller or shorter parts are easier to handle and easier to transport and store. In addition to these logistical advantages, the parts are individually replaceable and cheaper to produce. In addition, the breakage of a flexible part element does not lead to total failure of the machine.
  • the flexible elements may be attached by suitable attachment to the carrier or the holding jaws in the extension direction and in the transverse direction of the carrier so that thermal expansion is not transmitted.
