Definitions

  • the invention relates to a device for applying surface pressure to progressive workpieces, such as wood-based panels or the like, in which at least one rotating press belt can be pressed against the workpiece by a pressure medium that can be introduced into a pressure chamber, and the pressure chamber can be pressed through part of a working strand of the press belt. on the side opposite to the working area by a rectangular pressure plate and on the longitudinal and transverse edges of the pressure plate with respect to the running direction of the press belt by a seal provided on the edge of the pressure plate and supported on the press belt.
  • the invention is therefore based on the object of designing a device of the generic type in such a way that the mounting of the seal which is supported on the working strand on the pressure plate is simplified. This object is achieved by the measures mentioned in the characterizing part of claim 1.
  • the hose By pressurizing the interior of the hose with a pressure medium, the hose is positively and non-positively fixed in the assigned groove of the pressure plate. Due to the internal pressure of the hose generated by the pressure medium and the elastic deformability of the hose material, the sealing strip formed by a partial region of the hose or the sealing strip additionally fixed on the hose is pressed against the working area of the press belt.
  • Another significant advantage of the invention is that both the assembly and the disassembly of the entire seal is significantly simplified, which has a positive effect on the manufacturing costs and positive maintenance costs.
  • the device 1 has a lower frame 2 and an upper frame 3, in each of which endless press belts 4 are installed.
  • the press belts 4 run around deflection rollers 5 and are driven by them. They are arranged with respect to one another with a gap which corresponds to the width of a workpiece 6 to be machined. While the press belts 4 carry out a horizontal movement with their surfaces touching the workpiece 6, the workpiece 6 is drawn into the device, specifically into the gap that exists between the surfaces, and is pressurized there by the surfaces of the press belts. When the workpiece 6 passes through the device, it is processed so that it leaves the gap between the press belts 4 as a finished workpiece.
  • foils 7 are pressed onto the top and bottom of the workpiece 6 and are pulled off from supply rolls 8.
  • the pressing process can take place at room temperature or at higher temperatures which are applied to the workpiece in the machining area.
  • the upper frame 3 can be pressed against the lower frame 2 as a whole or, after a rough adjustment of the distance between the upper frame 3 and the lower frame 2, the required pressure can be exerted by means of an air pressure built up in pressure chambers 9 is, which are each arranged on the back of the press belt 4 with respect to the workpiece 6.
  • guide slides 10 are provided for the rough adjustment, which are fixedly arranged on the lower frame 2 and on which the upper frame 3 is displaceable in the vertical direction.
  • Hydraulic cylinders 11 are provided for the displacement.
  • the pressure chambers 9 are delimited on the side facing away from the working side of the press belt by pressure plates 12 which are guided relative to the frames 2 and 3 and the movement of which is carried out by hydraulic cylinders 13.
  • the pressure plate 12 can be rotated according to the illustration in FIG. 1 about an axis 14 running perpendicular to the working line of the press belt 4, so that the width of the pressure chamber can be adjusted to different workpiece widths due to its rectangular design with different side lengths.
  • a pressure medium can be introduced into the pressure chamber 9 through the pressure plate 12 via openings 15.
  • the pressure plate 12 has on its side facing the working side of the press belt 4 a circumferential groove 16 in which, according to the exemplary embodiment according to FIG. 3, a tube 17 with a round cross section is arranged.
  • the boundary of the groove 16 corresponds to the contour of the round hose.
  • the height h of the groove corresponds to approximately 2/3 of the outer diameter of the hose 17.
  • the hose is supported on the press belt 4 with the end protruding from the groove 16.
  • the pressure medium e.g. B. compressed air
  • the interior of the hose 17 is supplied via a channel 18.
  • the hose 19 which is likewise round in cross section, is equipped with a sealing strip 20 which is integral with the hose.
  • the hose 19 can be made of plastic or rubber.
  • the sealing strip 20 differs in consistency from the rest of the hose material and consists of an abrasion-resistant plastic or rubber.
  • the sealing strip 21 can also be made of the same material as the rest of the hose 22.
  • the sealing strip 21 is provided with an outer layer 23 made of metal or ceramic. A high abrasion resistance of the sealing strip is achieved through this outer layer.
  • the sealing strip 24 is anchored in a groove of an outer profile rail 25 which is connected to an inner rail 27 provided in the hose 26.
  • the connection between the outer rail 25 and the inner rail 27 is made by screws 28.
  • the tube 26 is oval in cross section and is fixed in a groove 29 of the pressure plate 12, which has a corresponding oval inner contour. Via a channel 30, the hose 26, the pressure medium, for. B. compressed air.
  • a hose 32 with a small diameter is arranged in the interior of the hose 31.
  • a pressure medium is applied to the inner tube, while a coolant 33 is filled in the annular space between the outer tube and the inner tube.
  • This coolant dissipates part of the heat generated in the working process, which reaches the area of the seal. This increases the life of the seal.
  • the hose 34 the interior of which is acted upon by a pressure medium, has a rectangular shape and is arranged in a groove 35 in the pressure plate 12 which is provided with a corresponding inner contour. From Fig. 8 it follows that the groove 35 is designed so that the hose 34 is positively fixed in this groove and only protrudes from the groove with the lower part provided with a sealing strip 36.
  • the sealing strip 36 is non-positively supported on the working strand of the press belt 4 under the influence of the pressure medium entered into the interior of the hose.
  • the tube 37 is triangular in cross-section and is arranged in a groove 38 of the pressure plate 12, which is also triangular and defines the tube 37 in a form-fitting manner.
  • the hose protrudes with a tip out of the groove 38. This tip is equipped with a sealing strip 39 which is supported on the working strand of the press belt 4.
