Definitions

  • the present invention relates to a hot stamping cylinder made of metal, arranged in the cylinder cavity heating.
  • Another method for heating the cylinder is based on the use of an electric heating cartridge in the cylinder center with energy supply via slip rings.
  • a hot stamping cylinder which has a heating system consisting of a heating plate arranged in the periphery of the cylinder. By means of a heat insulation mat prevents the cylinder interior is heated by the plate.
  • Object of the present invention was for hot stamping a heater in such a way that the known disadvantages no longer occur, an optimized heat distribution is possible and the whole can be achieved with the simplest possible means.
  • a simple clamping of the tools in the desired position on the cylinder can be achieved (expansion or shrinkage of the cylinder jacket larger than those of the ring or sleeve-shaped tools).
  • a very thin-walled cylinder made of aluminum with tools made of brass is used.
  • the thermal expansion of the cylinder is used as a clamping device for the tools.
  • the heating foil pressed against the inner wall of the cylinder it is possible to make the latter so that the heating power is applied in predetermined areas, e.g. at the end of the cylinder, higher fails to compensate for the higher heat flow through the cylinder bearings. This is achieved by always selecting the heating conductor distribution on the heating foil so tight that homogeneous heat distribution over the entire working width of the cylinder is ensured.
  • a uniform pressure of the heating foil to the cylinder inner wall is preferably achieved by expansion brackets, which at the same time allow any necessary replacement of the heating foil quickly and easily.
  • the thinner the wall of the cylinder the lower its heat capacity and the faster the heating and cooling times, thus the faster the reactivity with non-constant heat flow during operation.
  • the cooling time can be significantly shortened by additional forced air cooling of the cylinder (cooling fan).
  • the surface temperature of the cylinder is preferably controlled to a desired temperature and kept constant.
  • the control includes a temperature sensor, which e.g. integrated in the heating foil, in the cylinder jacket or otherwise inside the cylinder.
  • the subject invention allows a much easier process change in the printing part (embossing), a much more homogeneous heat distribution on the embossing cylinder (even in edge zones), a constant operating temperature thanks to rapid temperature control, short warm-up and cool down times and high efficiency thanks to local heat generation.
  • heating elements heatating foils
  • the invention also allows easy attachment of the tools by the thermal expansion occurring between the cylinder and tools (shrinking, clamping).
  • the hot stamping cylinder 1 shown in the drawing has a cylinder jacket 2 of aluminum and a. Against the cylinder inner wall pressed heating foil 3, the pressing by means of a plurality of resilient expansion brackets 4 takes place (the brackets 4 can be arranged at a mutual distance or immediately adjacent).
  • the cylinder 1 is mounted in known manner via end flanges 5, 6, in bearings 7, 8 and is driven, for example via a ring gear 9.
  • embossing tools 10 are made of brass (they are held by thermal expansion of the cylinder jacket 2 in the set position).
  • a temperature sensor 11 is integrated in the cylinder wall.
  • the heating foil 3 made of heat-resistant metal, has a large number of conductors adapted to the local requirements (looks similar to a perforated plate or an expanded metal foil).
  • the geometric design (different density distribution) is made by order of the manufacturer.
  • the heating foil 3 is preferably covered on both sides with a thin micaceous layer 12, 13 ( Fig. 2 ).
  • Towards the cylinder inside the heating foil 3 is also covered with an insulating mat 14 ( Fig.2 ), which comes to lie between the heating foil 3 and the brackets 4 (heat insulation against the inside).
  • the heating foil 3 and brackets 4 can be inserted from the side into the cylinder 2 with the hub 6 removed.
