Definitions

  • the invention relates to a nozzle plate holder and on a spinning beam for melt spinning endless threads from in particular thermoplastic materials (melt).
  • the spinning beam includes a heating box in which Melt lines, melt pumps and ends in nozzle plates Project nozzle pots (also called “nozzle packages").
  • the nozzle pots can have vertical indentations in the heating box form and, in bell-shaped recordings with vertical, central melt channel attached to one Melt inlet of the nozzle pots opens.
  • the nozzle plate holder forms part of a nozzle pot.
  • the top (inner) end of the nozzle package the connection with a carrier in the spinning beam created (see e.g. DE-C-1246221, DE-A-1660697 and US 4,696,633). This is true even if the package from above or from the side in the designated recording must be introduced (e.g. according to US 3,655,314 or US 3,891,379).
  • the nozzle pack has a flange at the bottom Fasten the end with screws - see for example US 4,494,921.
  • the fastener is mentioned in the Example used to provide the required sealing forces (by squeezing a sealing ring on the top End of the package). An air gap therefore remains between the flange and the support (the heating box).
  • a well-known spinning beam is from, for example DE-Gbm 84 07 945.
  • the receptacle for the nozzle pot (the nozzle package) in the The heating box is welded in and therefore a practical component of the heating box.
  • the arrangement of the nozzle pot in the holder is designed so that a stratification consisting of Nozzle plate, filter housing and nozzle pot bottom to the bottom the receptacle is screwed on, by means of the layering penetrating bolt, which in a nut thread in Are screwed in because of the recording.
  • the layering penetrating bolt which in a nut thread in Are screwed in because of the recording.
  • the nozzle pot with its components the screws be loosened, after which the nozzle pot extends vertically downwards the holder can be pulled out.
  • the nozzle pots need to be cleaned frequently, sometimes daily, by what depends on the mass to be processed, there is a considerable Wear of the bolts in the area of the nut thread in the bottom of the recording.
  • the bolts must be because of the Nozzle pot usually prevailing pressures from about 120 to 350 bar strong, which is to avoid Damage to the bolts and the thread with a torque wrench must be done.
  • the Attachment of a nozzle cup requires at least four bolts, so that for every cleaning of the nozzle pot too results in a significant amount of work.
  • a nozzle pot in a receptacle in Connection with a spinning beam is from the European Patent 163 248 known (see in particular Figures 3 and 6).
  • the nozzle pot has one Hollow cylinder on that with an inwardly projecting paragraph carries the nozzle plate on which the filter housing over a Ring seal is stored.
  • the unfilled nozzle pot over a membrane in the manner of an inverted plate supports the bigger picture.

This gives a particularly easy to close and connection to be released between the nozzle pot and the receptacle, namely only by turning at most about 90 °. Accordingly, the bayonet lock also joins frequent removal of the nozzle bowl practically no wear on.
  • Fig. 1 shows the heat flows on a nozzle package.
  • the melt makes up the majority of the Heat supply as well as heat dissipation. Ideally you are both heat flows equal in amount. That would mean, that the melt is one until it emerges from the nozzle has constant temperature. To ensure this would have to the other heat flows are in balance. Special Difficulties are caused by the heat loss from the nozzle plate. Since it cannot be isolated, a most of the heat in the form of radiation and convection released to the environment. This amount of heat must now as far as possible from the spinning beam to the nozzle package to the nozzle plate to cool the Reduce melt to a minimum.
  • the temperature difference to the diphyl temperature represents here is a measure of the amount of heat, that of the melt is withdrawn.
  • FIG. 5 shows a section of a spinning beam with a nozzle pack (in particular a nozzle plate holder) according to this invention.

If at Screwing in the threaded ring 11 of the projection 18 on the Surface 19 of the nozzle plate 9 rests is the entire Length of the nozzle cup 6 determined. Inside the cylindrical Projection 18 there is an annular recess, which is filled by the sealing ring 20. Of the Sealing ring 20 is a pressure to be processed Mass, the gap 21 between the surface 19 and the bottom surface 22 of the filter housing 10 fills, outwards against the cylindrical projection 18 pressed, which automatically under the effect of this pressure a seal adapted to the pressure between the filter housing 10 and the nozzle plate 9 results.
