Definitions
- Nozzle body for producing the finest liquid jets on water needling devices and methods for interlacing jets
- the invention relates to a nozzle body for the production of the finest liquid jets for the interlacing of endless or finite fibers in webs of chemical or natural fibers in nonwovens, tissues, woven or knitted fabrics, which preferably extends in a length that is transverse to the leading web Nozzle bar corresponding to the width of the material web is stored in a liquid-tight manner, a liquid pressure of up to 1000 bar being generated in the nozzle bar, which presses the nozzle strip against a wall of the nozzle bar provided with a flow slot, wherein a plurality of closely arranged ones are arranged in the nozzle strip to generate the liquid jets , smallest holes are made in diameter.
- a nozzle strip is e.g. B. is known from EP-A-0 725 175. It extends over a large working width and is generally made of a thin sheet of stainless steel with z. B. mechanically produced holes. This nozzle strip or the holes made in it have a geometry which has been tried and tested in practice and which is always improved, which is very expensive in the production process. The wall of the individual nozzle holes up to 0.1 mm in diameter must be extremely smooth, which is why the holes are drilled or punched.
- the geometry of the holes is of particular importance for the formation of the water jet, which is why a diffuse, conical part adjoins the height of the nozzle hole generally behind a nozzle cross section that determines the water jet, and also does not pass through the water jet formed on the way to the end of the hole Tearing up friction on the walls of the hole.
- the holes quickly become unclean in the edge areas due to the water pressure that is increasingly desired in practice and also because of the constant abrasion. This creates blurry, out-of-round water rays that only bring an unsatisfactory energy into the dynamic treatment of the web.
- the invention has for its object to develop a nozzle body, a nozzle strip, in which precisely formed, extremely smooth over the effective length nozzle holes can be generated and the inner surface are resistant to abrasion even for a long time.
- a hard metal or a ceramic material or a material that has the same or similar physical properties is selected as the material for the nozzle body.
- Synthetic rubies and sapphires, i.e. monocrystalline aluminum oxides are also to be understood here.
- the materials are brittle, in particular ceramics, so that the group of hard metals with a high modulus of elasticity is to be preferred first.
- Hard metals are two or multi-phase alloys made by powder metallurgy with a metallurgical binder. Hard metals can be divided into groups K, M and P:
- K group tungsten carbide-cobalt alloy is characterized by high hardness.
- these materials are particularly suitable for laser beam or spark erosion treatment.
- the cut edges when lasering in this material can be cut smoothly, so that it may even be unnecessary to rework the holes.
- the result is better for spark erosion and particularly good for drilling with diamond drills.
- the nozzle body, with its material thickness, can preferably form the nozzle hole at full height, which means that the conical enlargement to the outlet of the hole hm, which has to be introduced up to now, is eliminated.
- the holes should have a diameter of 0.08 to 0.15 mm and the hole spacing should be between 20 and 128 hpi in one or two rows.
- the thickness of the nozzle body is between 0.8 and 2 mm.
- the length of the nozzle hole punch can also be considerably larger, such as up to 3 mm or more
- a particular advantage is given by the idea according to the invention in that the entire nozzle strip does not have to be made from one and the same material.
- a load-bearing material such as, for example, stainless steel, should carry the other material for the actual nozzle body or bodies full area but also only with respect to a single nozzle body
- the nozzle body for larger working widths. Since the hard metal or a ceramic material is very brittle, it was possible to store the material forming the nozzle holes in a more stable frame or to apply the material to a support, e.g. made of stainless steel
- the nozzle body could thus be made of the aforementioned hard materials over the entire length of the nozzle strip or only as a small to smallest unit, each provided with a wall, for example a cylindrical unit made of hard metal, ceramic or a sapphire, and thus as a single part on the other Fen-shaped support material such as stainless steel is propped up and held there.
- a large number of these individual shower body parts are then to be arranged and fastened directly next to one another or in bores provided for this purpose.
- the fastening can be carried out by gluing
- FIG. 1 shows a section across a nozzle bar, as disclosed in EP 0 725 175
- FIG. 2 shows the top view of a nozzle strip with individual nozzle bodies, which are made from others on a nozzle strip 3 shows a section through the nozzle strip according to FIG. 2, 4: the top view of a nozzle strip with individual nozzle bodies which are very close to one another and which are carried on a nozzle strip made of a different material, and
- FIG. 5 shows a section through the nozzle strip according to FIG. 4.
- the housing of the nozzle bar consists of an upper part 1, which is screwed to the lower part 2 many times over the length by the screws 3 from below.
- the upper part 1 has two bores 4 and 5, the upper of which is the pressure chamber 4 and the lower one the pressure distribution chamber 5. Both chambers are open on one end and screwed tight again through the cover.
- the two chambers 4 and 5 are separated from one another by an intermediate wall.
- a large number of flow bores 9 in the intermediate wall connect the two chambers along the length of the nozzle bar, so that the liquid flowing into the pressure chamber 4 flows uniformly over the length into the pressure distribution chamber 5, in which an impact body 20 is additionally held on brackets 21 ,
- the pressure distribution chamber is open at the bottom, namely through the slot 10 which is narrow in relation to the diameter of the bore of the pressure distribution chamber 5 and which also extends over the length of the beam.
- the upper part 1 is screwed to the lower part 2 firmly and in a liquid-tight manner.
- the tightness is caused by the O-ring 1 1, which lies in an annular groove of the upper part 1.
- the slot 10 encloses a spring projection 23 which is fitted into a corresponding groove 24 in the lower part 2 and which has a repair groove 26 for the O-ring 12, the outer edges 25 of which rest against the edge of the Nozzle strip 14 are directed.
- an annular groove is again introduced, in which the O-ring 12 lies for sealing the nozzle strip 14.
- a slot 13 is also made in the lower part 2, which is only very narrow in its upper region and leaves only a little more than the width of the effective nozzle openings of the nozzle strip 14 open.
- the nozzle bar can also look very different, namely as disclosed for example in DE-A-199 21 694.
- the nozzle strip 14 has a certain width, which is necessary for receiving the nozzle holes 30 and for storage above the O-ring 12. If nozzle bodies are produced as individual parts 31 and are mounted on the nozzle strip 14, then they are held in individual recesses 32 of a material that accommodates the nozzle bodies 31. This material can be that of a separate nozzle strip 33, as shown in FIGS. 3 and 5. This is advantageous in that the recesses 32 can be introduced transversely through the nozzle strip 33.
- This nozzle strip is then placed on a carrier strip 34, which in turn has holes 35 in line with the arrangement of the nozzle bodies 31 in such a way that they are larger in diameter and larger than the holes 30 provided for shaping the nozzle jet, so that the water jets are unimpeded through the entire strip 14; 33, 34 can flow.
- the nozzle bodies 31 are to be made from the hard, resistant material.
- the material of the strip 33, 33 ' can be made of stainless steel, but that of the carrier strip 34, 34' can also be made of a hard, stiff material, such as hard metal, in order to reduce the elasticity of the long strip desired in practice.
- the nozzle bodies 31 For the uniform needling effect, it is better to arrange the nozzle bodies 31 directly next to one another on the carrier strip 34 ', as is shown in FIGS. 4 and 5. This enables the jet streams to be generated closer together, as is required in the water needling industry. In any case, it is advantageous to arrange the nozzle bodies 31 in two rows (FIGS. 2 and 4) offset from one another. In the case of the example according to FIG. 4, no holes need to be drilled into the material of the strip 33 'to hold the nozzle body 31, but only boundaries 32' (possibly circular segments) on both sides in order to fix the nozzle body 31 laterally.
- the nozzle body 31 is glued in the strip 33, 33 'and / or on the carrier 34, 34'.
- the bores 31, as in the individual nozzle bodies 31, are exactly cylindrical over their entire length.
- the edge of the water inlet hole is sharp and that of the water outlet. In any case, no conical widening is provided at the outlet end of the nozzle hole 30, as was previously considered necessary.
- the representation in FIGS. 2-5 is greatly enlarged.
- the hole spacing should be 20 to 128 hpi.
- the diameter of the nozzle body 31 is thus around 1 mm, and the nozzle holes 30 themselves are accordingly fine, namely 0.08-0.15 mm.
- nozzle bodies 31 are mounted as individual parts on the carrier strips 34, 34 '. It is also possible to produce the strips 33, 33 'entirely from the hard material and to provide them with the nozzle holes 30 directly and then to use them alone as a nozzle strip or to store them on the strips 34, 34', which itself is not as brittle is and z. B. is made of stainless steel.
