Definitions

  • the invention relates to a spinning device according to the preamble of claim 1.
  • This spinning device is the subject of EP 363 317-A.
  • the invention is accordingly based on the object of eliminating these difficulties and proposing a spinning device with which a multiplicity of nozzle pots arranged on a circle can be easily mounted and uniformly heated in a common heating box.
  • the advantages of the specified solution lie in a compact design of the spinning device with a nozzle head which contains all the nozzle pots with the nozzle packages, and the heating box which closely surrounds the nozzle head and is common to all nozzle pots.
  • the installation and removal of the nozzle head in the heating box is also simple, since the nozzle head is attached as a whole unit to the underside of the distributor or pump block, which in turn closes off the nozzle shaft at the top.
  • the specified solution is also advantageous from a thermal point of view, since the nozzle pots are arranged symmetrically in the nozzle head and heat losses in the nozzle shaft of the heating box, which is closed at the top, are avoided.
  • the specified spinning device it is possible with the specified spinning device to spin a large number of threads with a small pitch. In contrast to previous solutions, the division of the spinning machine, including drawing and winding, is no longer dependent on the division of the spinning device, which is arranged above the spinning machine.
  • the invention has the advantage that all filaments can be spun very evenly.
  • the large number of nozzle openings of a nozzle pot is fed by only one pump. This is acceptable for all applications in which only one thread is formed from the large number of spun filaments. If a nozzle opening is completely or partially blocked in such a case, the melt flow is distributed to the other nozzle openings, but the titer of the individual filaments changes only slightly according to the large number of filaments, and the total titer of the thread is retained.
  • the embodiment according to claim 4, which also contributes to the homogenization of the filaments, is also very favorable in terms of mechanical engineering, in particular spatially but also thermally, since it allows a very compact design of the pump and the pump block which is adapted to the design of the nozzle cup.
  • the design according to claim 5 is very cheap in terms of production technology, since the nozzle head can be manufactured as a turned part. However, it is also particularly favorable in terms of heat technology, since it ensures uniform heat distribution over the individual nozzle pots. The same advantages are to be mentioned for the training according to claim 6.
  • the training according to claim 7 allows easy assembly and easy maintenance. It is particularly advantageous that the nozzle head can be installed and removed and serviced from below.
  • the spinning device in FIGS. 1 and 2 is accommodated in a heating box 1.
  • the heating box 1 is a cylindrical body with an inner jacket and an outer jacket. The two coats form a hermetically sealed cavity between them, which is filled with a heating medium, heating liquid.
  • the cylindrical inner jacket 2 also forms the nozzle shaft.
  • the cylindrical nozzle shaft 2 has a step 3 in front of its lower part.
  • a distributor block 4 rests on step 3.
  • the distributor block 4 almost completely fills the cross section of the nozzle shaft in the upper part. There is therefore good heat-conducting contact between the walls of the nozzle shaft 2 and the distributor block 4.
  • the pump block 5 is located on the distributor block 4.
  • the pump block 5 contains several gear pumps, which are only indicated here.
  • planetary gear pumps are preferably used, each having a central gear and a plurality of planetary gears distributed over the circumference, which mesh with the central gear.
  • the pump is fed through the melt line 6 and feeds into the pump lines 7.
  • the melt line 6 and the pump lines 7 are arranged in the distributor block.
  • the central wheels of the two pumps are driven by pump shaft 21.
  • the melt line 6 is arranged in the distributor block 4. It connects the pumps to an extruder line 24.
  • the extruder line 24 is fed with a meltable spinnable polymer, for example polyethylene terephthalate, through a spinning extruder, not shown.
  • the extruder line 24 is surrounded by an insulating jacket and penetrates the cavity between the inner jacket 2 and the outer jacket of the Heating box 1 by means of a pressure-tight welded cylindrical tube 25.
  • the pump lines are also formed in the distributor block 4. Each of these pressure lines 7 connects a pump outlet to a nozzle packet.
  • a planet gear pump forms a separate pump with each of its planet gears, the pressure build-up of which is independent of the pressure build-up of the other pumps.
  • the two planetary gear pumps shown form eight pumps. Each of these eight pumps is connected via a pressure line 7 to a nozzle packet 10.
  • the spinning device has - as shown in FIG. 2 - eight nozzle packs.
  • the structure of the nozzle packs 100 is the same.
  • a nozzle head 9 is used to receive the nozzle packs.
  • the nozzle head 9 is a cylindrical body, the outer circumference of which is closely matched to the lower part of the nozzle shaft 2.
  • the nozzle head is fastened to the distributor block 4 by a central screw 8.
  • it has, on its side facing the distributor block 4, an abutment ring 20, with which it is firmly clamped against the distributor block 4 by means of the screw 8.
  • the nozzle head 9 has a groove 22 in which a wedge 23 meshes.
  • the wedge 23 is attached to the inner jacket of the nozzle shaft 2. Through the groove and the wedge, the straight head of the nozzle head 9 is effected in the heating box.
  • the nozzle head 9 has eight circular cylindrical holes on a circle concentric with its central axis, each of which forms the nozzle pot 10 and serves to receive the nozzle package 100 consisting of the nozzle plate 12, filter plate 13, filter 14, seal 16 and sealing piston 15.
  • Each of the nozzle pots 10 has an enlarged diameter in its upper region, which forms a step 26 in relation to the lower region.
  • the nozzle plate 12 can in particular be a monofilament nozzle through which a filament is spun out. However, several filaments can also be spun out. However, the use of this invention is preferred in the spinning of monofilaments.
  • the nozzle plate rests on a circumferential collar 11 which delimits the lower end of each nozzle pot 10 and only releases the passage of the nozzle plate 12.
  • the filter plate 13 serves to support the filter 14. These elements have the larger diameter of the nozzle cup. The smaller diameter has the seal 16 and the sealing piston 15.
  • the sealing piston 15 is slidably guided in the nozzle cup 10 with play.
  • the sealing piston 15 has a connecting bore 19 centrally. On its end face facing the distributor block 4 there is a central annular projection 18 with a connection seal 17.
  • the connection seal 17 consists e.g. made of a soft metal, which lies sealingly against the distributor block 4 by the forces acting on the sealing piston 15. It should be emphasized that the connecting bore 19 is aligned with one of the pump lines 7.
  • the respective nozzle pot 10 is charged with melt under pressure. As a result, pressure builds up in the nozzle pot 10.
  • the gap between the nozzle cup or its jacket and the sealing piston 15 is sealed by a seal 16 which presses into the gap as a result of the pressure build-up.
  • the seal 16 is a ring with an angular cross section, which on the one hand covers the gap, but on the other hand leaves the connecting bore 19 exposed. It is a self-sealing system, as is similarly described in US Patent 4,698,008.
  • the seal 16 and the sealing piston 15 have - as said - the enlarged diameter and are therefore on the step 26.
  • the axial extent of this diameter expansion is so large that the connection seal 17 bears against the distributor block 4 essentially without play in the installed state.
  • the distributor block 4 and the pump block 5 are first placed in the nozzle shaft 2 from above.
  • the distributor block 4 is then connected to the extruder line 24.
  • the pump block 5 is clamped to the distributor block 4 from above in a manner not shown and fixed in the nozzle shaft.
  • Fig. 1 it is only indicated by arrows that the pump block 5 is pressed by clamping forces from above against the distributor block 4 and the distributor block 4 against the stage 3.
  • the spinning head 9 is assembled in the disassembled state. That is to say, the nozzle plate 12, the filter plate 13, the filter 14, the seal 16 and the sealing piston 15 with the connecting seal 17 are inserted one after the other into each nozzle pot 10. Then the spinning head 9 with the built-in nozzle packs 100 is mounted in the nozzle shaft 2 of the heating box 1 and fastened in the distributor block 4 by the screw 8. By tightening the screw 8, the connection seals 17 between the distributor block 4 and the sealing piston 15 of the nozzle packs 100 are also slightly prestressed.
  • the heater box shown in FIG. 3 corresponds in structure to the heater box described in US Pat. No. 4,698,008.
  • the heater box is therefore designed as a bar.
  • the underside has the nozzle shafts 2. In each of the nozzle shafts there is a nozzle head 9 with eight nozzle pots.
  • the structure of the nozzle heads 9 corresponds to the description according to FIGS. 1/2.
  • the spinning device shown in Fig. 1, 2 also shows a very compact and therefore space-saving structure for heat transfer with regard to the heating box
  • the spinning device according to Fig. 3 is characterized in that several spinning heads 9 can be accommodated in a single heating box 1 .
  • Which of the versions should be preferred depends on the spatial conditions.
  • this embodiment is particularly suitable for the production of monofilaments which must have a particularly high dimensional accuracy from filament to filament and over the length of the filament.
