Definitions

  • the invention relates to a doctor blade holding device with the features specified in the preamble of claim 1.
  • Such a doctor blade holding device can be used, for example, in a paper mill in papermaking or in the steel industry. It serves to receive a scraper blade for the purpose of even contact with a rotating roller or roller in order to clean the surface during operation.
  • a roller may have a width of several meters.
  • the scraper blade provided for cleaning such a roller must rest over the entire length of the roller as uniformly as possible at a predetermined angle to the roller. To accomplish this, the doctor blade is generally applied to the roller at a relatively high pressure.
  • a scraper for scraping a Toiletmaschinen- or the like cylinder with a doctor blade which is mounted in a holder known.
  • the retainer includes a main support member extending parallel to the cylinder for applying pressure to the doctor blade to be pressed against the cylinder, a rigid support plate extending from the support toward the cylinder, a hinge rod mounted below the support plate and parallel to the cylinder, and a blade holder for receiving the rear end of the scraper blade, which extends from the hinge rod to the front of the cylinder, on.
  • a fluid-filled bellows is provided which extends between the support plate and the blade holder formed by hinge plates and between the rear end of the doctor blade and the hinge rod parallel to the length of the doctor blade.
  • a doctor blade holding device which has two holding elements. Between the said holding elements, a first part of the doctor blade is introduced. The second part of the doctor blade leads away from the holding elements.
  • One of these retaining elements is a plate consisting of a plurality of fiber layers. The number and orientation of these fibrous layers depends on the desired working conditions of the doctor blade.
  • two pneumatic hoses are provided, of which - from the perspective of the doctor blade - one in front of and one behind a fulcrum.
  • Fulcrum is provided in the central region of the base plate.
  • the desired contact pressure of the doctor blade can be adjusted to the roller.
  • the known device has a flexible seal which is intended to prevent the introduction of dust and other foreign bodies. Since this flexible seal must extend over the entire length of the roller, the implementation is complicated.
  • heat resistant gaskets must be used, such as Viton gaskets. This is very expensive.
  • a scraper arrangement which has a blade carrier and a scraper blade.
  • the blade carrier is pivotally mounted about an axis on a blade holder, wherein between the blade carrier and the blade holder at least one pressure element is arranged, which is self-similar regardless of the pressure, d. H. maintains its basic shape.
  • a pressure element is arranged on both sides of the axis.
  • the axis is in the central region of the base plate or blade holder.
  • the invention has for its object to provide a doctor blade holding device in which the above-mentioned disadvantages do not occur.
  • the cover plate is connected to a slotted square tube within which the provided in an end region of the base plate bearing tube is rotatable.
  • the cover plate can be removed in a simple manner, so that cleaning work within the device and replacement of the air hose are facilitated. In particular, it is not necessary to unscrew a plurality of screws in order to remove the cover plate can.
  • the doctor blade holding device manages with only one hose. If the hose is filled with air, then this leads, depending on the air pressure, to a greater pressure of the doctor blade on the roller to be cleaned. At the same time a spring is pulled apart or stretched. If the air is drained from the hose, then the scraper blade is lifted off the roller to be cleaned by the spring which contracts or relaxes again. A second tube, as provided in the previously known arrangements, is not necessary. The said spring return is necessary, for example, to change the doctor blade.
  • a part of the cover plate, the square tube, the base plate and the shoe form a substantially dustproof unit.
  • the doctor blade holding device shown in Figure 1 has a base plate 6 which is formed substantially U-shaped and has two short and one long boundary wall. In the end of one of the short boundary walls, a bearing tube 5 is arranged, which is part of the base plate. The bearing tube 5 is mounted within a slotted square tube 4 and rotatable about a small angle to this.
  • the square tube is fixedly connected to a cover plate 2, preferably by means of a plurality of screw connections which are arranged perpendicular to the plane one behind the other, but are not shown in the drawing.
  • the cover plate 2 is preferably made of carbon fiber material and may have multiple carbon fiber layers. As a result, the cover plate is flexible and can adapt well to the surface of each roller to be cleaned.
  • finger devices 3 are fastened to the cover plate by means of screw connections 3 a, which are also arranged one behind the other perpendicular to the plane of the drawing.
  • screw connections 3 a which are also arranged one behind the other perpendicular to the plane of the drawing.
  • the doctor blade 1 is introduced. This introduction of the scraper blade is preferably carried out by insertion in the axial direction. Since the rear end portion of the doctor blade is provided with a rivet or spring 15, the doctor blade can not be pulled out in the direction of the roller to be cleaned during operation.
  • a pneumatic air hose 14 is provided in the interior of the U-shaped base plate 6. This is provided at its one end with an air connection, through which air can be pressed into the hose and also air from the hose can be omitted. The other end of the tube 14 is closed. Between the tube 14 and the long boundary wall of the U-shaped base plate 6, a plastic insert 7 is provided. This is loosely inserted, glued or screwed on the inside of the base plate and prevents the hose 14 comes into contact with a possibly hot boundary wall during operation of the device.
  • a spring 8 is provided in the interior of the U-shaped base plate 6. Whose one end is connected to the long boundary wall of the base plate 6. The other end of the spring 8 is fixed to a shoe 10, which is provided for receiving the rear end portion of the cover plate 2.
  • the shoe forms in a direction perpendicular to the plane of a guide rail, within which the cover plate is mounted displaceably in the axial direction.
  • the shoe is provided with a sliding surface 11, which is arranged parallel to a boundary wall 9 of the U-shaped base plate.
  • the shoe 10 is pivotable together with the cover plate relative to the base plate. This pivotability is given by the fact that in the boundary wall 9 of the base plate in the radial direction extending slots 13 are provided, through which associated with the sliding surface 11 of the shoe rivets 12 are guided.
  • doctor blade 1 If the doctor blade 1 is to be lifted off the roll surface again, for example, to a blade change, then the air is discharged from the hose 14. By then retracting spring 8 of the shoe 10 is moved back in the plane to the left to its original position, so that the cover plate 2 is pivoted back to its original position.
  • the design of the doctor blade holding device according to the invention also makes it possible to make do with only one air hose, since the bringing about the initial position of the cover plate is done using a relaxing spring.
  • the system formed from the base plate, the shoe, the square tube and a part of the cover plate forms a substantially dustproof unit.
  • the doctor blade holding device shown in Figure 2 has a base plate 6 which is formed substantially U-shaped and has two short and one long boundary wall. In the end of one of the short boundary walls, a bearing tube 5 is arranged, which is part of the base plate.
  • the bearing tube 5 is mounted within a slotted square tube 4 and rotatable about a small angle to this.
  • the square tube 4 may be constructed segment-shaped in the direction perpendicular to the plane to affect the elasticity of the cover plate 2 as little as possible.
  • the square tube is firmly connected to the cover plate 2, preferably by means of a plurality of screw connections, which are arranged perpendicular to the plane one behind the other, but are not shown in the drawing.
  • the cover plate 2 is preferably made of carbon fiber material and may have a plurality of carbon fiber layers. As a result, the cover plate is flexible and can adapt well to the surface of each roller to be cleaned.
  • the doctor blade 1 is introduced in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 in the front end region of the cover plate 2 are by means of screw 3a finger devices 3 on the cover plate attached, which are also arranged perpendicular to the plane in a row. Between the cover plate 2 and the finger devices 3, the doctor blade 1 is introduced. This introduction of the scraper blade is preferably carried out by insertion in the axial direction. Since the rear end portion of the doctor blade is provided with a rivet or spring 15, the doctor blade can not be pulled out in the direction of the roller to be cleaned during operation.
  • a pneumatic air hose 14 is provided in the interior of the U-shaped base plate 6. This is provided at its one end with an air connection, through which air can be pressed into the hose and also air from the hose can be omitted. The other end of the tube 14 is closed. Between the tube 14 and the long boundary wall of the U-shaped base plate 6, a plastic insert 7 is provided.
