Definitions

  • the invention relates to a plate press for the production of multilayer plates, in particular coated rigid foam plastic plates, with a lower press plate and an upper press plate arranged in at least one portal frame, the one press plate being mounted in a fixed position, the other press plate being movable up and down and the lower press plate with one Longitudinal material to be pressed is provided.
  • Plate presses of this type are mainly used in the course of coating hard foam plastic sheets with plywood sheets and, or laminating foils, with the sheets layered with the interposition of binder layers - if necessary several times in stacks - are pressed in the plate press until the binder has hardened.
  • the press plates consist regularly of steel, the upper press plate being stationary, while the lower press plate can be moved up and down with the aid of an inflatable cushion, and the longitudinal transport device consists of a roller conveyor integrated into the lower press plate .
  • the design effort is considerable; It must be taken into account that flatness and parallelism must be given for press plate lengths of 50m and more.
  • the roller conveyor integrated in the lower press plate also creates manipulation problems; During longitudinal transport, the previously precisely aligned individual layers of a plate or a stack can slip against one another, and a lower lamination film can also get caught on the roller conveyor. So far, all of this has been accepted as inevitable.
  • the invention has for its object to develop a plate press of the type mentioned so that it is much cheaper to manufacture and allows an undisturbed long material transport.
  • the lower and the upper press plate are each designed as a concrete plate with reinforcement made of structural steel mesh and I-steel longitudinal members connected to it, with the I-steel longitudinal members protruding from the concrete plate and forming longitudinal chambers stationary lower press plate provided with blown air passages, the upper pressing surface forming plywood plates are attached and the I-steel longitudinal beams of the movable upper press plate are connected via hydraulic cylinder piston assemblies to the portal frame or frames.
  • the press plates thus consist of reinforced concrete plates, while the longitudinal material to be pressed is designed, as it were, as an air cushion generating device.
  • the concrete slabs can easily be manufactured at the installation site of the plate press with plane-parallel pressing surfaces.
  • the air cushion permits extremely gentle treatment of the material to be pressed. Everything is made possible at a particularly low cost price;
  • a plate press according to the invention it is possible to reduce the production costs to approximately 20% of the costs of a known plate press with steel press plates.
  • the press plates consist of a concrete B 17.5 of class 1, consistency area 3 according to NEN 3861 (Nederlands Normalisatie-Instituut April 1974).
  • the I-steel longitudinal beams are expediently welded to the structural steel mesh mats.
  • plane parallelism of the press plates can be achieved in a particularly simple manner.
  • the arrangement is such that the pressing surface of the upper press plates is designed as a complementary surface to the lower pressing surface.
  • the lower press plate whose plywood plate forms the lower press surface, can be worked on flatness without great problems.
  • the parallelism of the upper press plate can be achieved simply by producing the upper press plate by concrete casting on this separating film.
  • the upper press plate it is advisable to attach the upper press plate to the assigned portal frame using two hydraulic cylinder piston assemblies.
  • the blown air passages each consist of a stepped bore in which a ball, in particular a steel ball, is held with an upper insert ring, for example made of plastic.
  • the lower press plate it is advisable to level the lower press plate with longitudinal transport chains arranged between adjacent plywood plates, the upper run of which is by means of an air cushion over the lower one Press surface can be highlighted: other means can be used instead of the air cushion.
  • the plate press shown in the figures is used to manufacture multi-layer plates, in particular coated rigid foam plastic plates, and consists in its basic structure of a lower press plate 1 and an upper press plate 2, which is arranged in two portal frames 3.
  • One press plate 1 is stationary.
  • the other press plate 2 mounted to move up and down.
  • the lower press plate is provided with a material to be transported longitudinally 4.
  • the lower and the upper press plate 1, 2 are each designed as a concrete plate with reinforcement made of reinforcing steel mesh 5 and I-steel longitudinal members 6 welded to it.
  • a plywood plate 10 provided with blowing air passages 8 and with its upper side forming the internal pressing surface 9 is fastened.
  • the 1-steel longitudinal members 6 of the movable upper press plate 2, which can be supplemented by additional I-steel cross members 11 in the upper press plate 2, are each connected to the portal frame 3 via two hydraulic cylinder piston assemblies 12.
  • the press plates 1, 2 consist in particular of a concrete B 17.5 of class 1, consistency area 3 according to NEN 3881.
  • the press surface of the upper press plate 2 is designed as a complementary surface to the lower press surface 9, which in the above - has already been achieved.
  • the blown air passages 8 each consist of a stepped bore 13 in which a ball 14 made of steel is held by an upper insert ring 15 on plastic.
  • the longitudinal chambers 7 are connected to a compressed air source. 4 that the lower press plate 1 is provided with longitudinal transport chains 15 arranged between adjacent plywood plates 10, the upper run of which can be highlighted by means of an air cushion over the lower pressing surface 9.
  • the plate press can be supplemented, as it were, by further press plates, the lower press plates 1 being combined into a single lower press plate.
  • the portal frames 3 of adjacent plate presses can also be integrated into one another.
