Definitions
- the invention relates to a melt blow head with a straight line of nozzle bores arranged in a nozzle pack, which are used to produce continuous filaments formed from a melt, to which blower feed gaps formed as longitudinal gaps are assigned to two blower plates for obliquely supplying blown air to the nozzle bores and which are assigned via one or the melt is fed several times in the melt blow head, the distributor or distributors being supplied with the melt by a feed line.
- melt blow head is described and shown in European patent specification 0 625 939 B1 (see DE 693 19 582 T2).
- the known device is used to create a tangle of threads from the continuous threads it dispenses, which can then be used as a known nonwoven fabric.
- the melt blow head according to the invention described below can advantageously be used in the same way.
- the nozzle assembly forms a unit by screwing it to the split plates, which is arranged to be pulled out of a housing in the longitudinal direction for cleaning or maintenance.
- the continuous filaments are squeezed out of the melt blow head in a vertical direction and then, after having passed through a cooling section in a tangled position relative to one another, are conveyed to a conveyor belt which transports the structure of tangled continuous filaments as a fleece.
- the melt required for the production of the continuous filaments is introduced vertically from above through the housing into the melt blow head, the blown air is supplied from both sides via air chambers, from which the blown air is then directed to the blown feed gaps.
- the lateral pulling out of the melt blow head from the housing is due to the fact that the feed for the melt protrudes vertically upwards from the housing.
- the object of the invention is to improve the adaptability of the melt blow head to the environment, which is required for the maintenance or cleaning of the melt blow head.
- This is done according to the invention in that the feed line in the melt blow head leads from a lateral inlet, which is connected to a melt pipe via a removable connection, via a deflection in a substantially vertical direction to the distributor, the nozzle packet being fixed in a defined position relative to the split plates and is detachably mounted in an approximately vertical direction.
- the space above the nozzle package remains free of feed lines, so that Nozzle pack can be lifted from the split plates in a vertical direction, for which purpose the nozzle pack is removably mounted on the split plates.
- the space above the nozzle package is generally free of any components or system parts, so that the removability of the nozzle package in the vertical direction leads to a problem-free cleaning or maintenance process.
- an automatic alignment of the nozzle pack with the split plates can also be achieved, namely in that the nozzle pack is laterally enclosed by air supply inlet blocks with horizontal and vertical walls arranged parallel to the row of nozzle bores, on which the nozzle pack is attached one level with high Rizontalem and vertical leg abuts, each with a split plate on an air supply block against a stop and leaves a space for supplying the blown air to the longitudinal gaps to the air supply block.
- the position of the nozzle packet in terms of its position in the vertical and horizontal directions is kept exact, whereby the position of each split plate on an air supply block against an abutment also exactly adheres to its position.
- the nozzle packet and split plates are taken apart and then reassembled, the nozzle packet and split plates are returned to their precisely aligned position, so that this reassembly does not require any special adjustment to the nozzle packet. This exact location is crucial for the proper functioning of the meltblower head.
- shut-off valve is expediently provided with a shut-off valve in the region of the connection to the nozzle pack.
- melt tube does not hinder this process when the nozzle block is lifted off
- connection it is also possible to give the connection a deformable seal which, in the area of its deformability, results in a space between the connection and inlet, as a result of which the nozzle package can be raised unhindered by the melt pipe.
- the side of the split plates facing away from the nozzle package is expediently designed in the form of a concave rounding, which ensures a largely vortex-free course of the ambient air entrained with the blown air.
- Figure 1 shows the melt blow head with heating box in a perspective view
- Figure 2 shows the same arrangement in side view in section
- FIG. 2a shows the area of the longitudinal gaps 25 and 26 from FIG. 2 in an enlarged manner
- Figure 3 shows the arrangement of Figure 2 with rounded split plates.
- Figure 1 shows a melt blow head with the nozzle pack 1 and two split plates
- the nozzle package 1 shown here in one piece can also be composed of several components to form a block.
- the two air supply blocks 4 and 5 are fed by the two air lines 6 and 7 in a known manner.
- the feed line 9 runs in the nozzle packet 1, which leads via the deflection 10 to the inlet 11 in the nozzle packet, where the connection to the melt line 13 takes place via the connection 12.
- nozzle packages usually consist of several plates or parts.
- melt pumps 14, 15, 16 in the system shown and 17 are provided, from which, as shown in connection with the fusible line 13, the relevant nozzle bores are supplied in the course of the nozzle packet 1.
- the melt pumps 14, 15, 16 and 17 and the associated melt lines 13 are accommodated in the heating box 18, in which the melt located there is kept at the melting temperature.
- FIG. 1 shows heating plates 19, 20 and 21, which will be discussed in greater detail in connection with FIG. 2. 1 then shows the heads 22 and 23 of a series of screws, which are also discussed in greater detail in connection with FIG. 2.
- FIG. 2 the arrangement according to FIG. 1 is shown in section as seen from the side.
- the nozzle package 1 forms a block containing the feed line 9 and the deflection 10, in which the melt supplied is distributed to the individual nozzle bores 8 by the distributor 24 (see FIG. 1) in the nozzle package 1.
- FIG. 2a represents an enlargement of the relevant part from FIG.
- the two gap plates 2 and 3 each leave a longitudinal gap 25 and 26 free at the end of the nozzle bore 8, from which blown air flows out and the melt emerging from the nozzle bore 8 cools and removes it. Blown air is supplied to the longitudinal gaps 25 and 26 from the air pipes 6 and 7 via the lines 27 and 28, which run within the air supply blocks 4 and 5 and end in spaces 29 and 30, which between the split plates 2 and 3 on the one hand and the nozzle pack 1 and the air supply blocks 4 and 5 exist.
- the design and effect described above of the end of the nozzle bore 8 with the longitudinal gaps 25 and 26 is known and is shown in principle in the publication mentioned at the beginning.
- the feed line 9 leads via the deflection 10 to the side inlet 11, which is connected to the connection 12, which has a deformable seal 45.
- the connection 12 is preceded by the shut-off valve 31, which serves to prevent the further inflow of melt from the melt pump 14 in the event of the nozzle pack 1 being removed as described below.
- the shut-off valve 31 serves to prevent the further inflow of melt from the melt pump 14 in the event of the nozzle pack 1 being removed as described below.
- the bellows 32 At the end of the melt line 13, it leads through the bellows 32, which ensures that a certain flexibility can exist between the connection 12 and the melt line 13.
- the nozzle pack 1 has the steps 33 and 34, each of which has a horizontal and a vertical leg 35, 36 (only shown with reference numbers in connection with the step 33). These legs 35 and 36 rest against corresponding wall parts of the air supply blocks 4 and 5, which run horizontally and vertically and thus allow steps 33 and 34 to be fitted.
- the nozzle packet 1 is connected to the air supply blocks 4 and 5 by means of the horizontal screws 37 and 38 (horizontal screws 37 with the screw heads 22 see FIG. 1) and the vertical screws 39 and 40 (screw heads 23 of the vertical screws 39 according to FIG. 1). Tightening these screws results in a fixed unit including the nozzle package 1 and the two split plates 2 and 3, which results in a precise alignment of the nozzle bore 8 with the gaps 25 and 26.
- the split plates 2 and 3 are given a special orientation in the direction of the nozzle bore 8 in that the split plates 2 and 3, with their ends facing away from the longitudinal gaps 2 and 3, against the insertable spacers 41, which vary in thickness and form a stop and 42 start up and are tightened against them by means of screws 43, 44.
- the split plates 2 and 3 are pressed against the air supply blocks 4 and 5 by means of the screws 45 and 46.
- the nozzle packet 1 is reinserted in the opposite direction, the nozzle packet 1 merely being inserted between the two air supply blocks 4 and 5 and the screws loosened previously being reinserted and tightened.
- the nozzle pack 1 assumes a position defined by steps 33 and 34.
- the air supply block 4 has a position defined by a further external structural unit
- the further components of the unit consisting of the nozzle package 1, air supply block 5 and split plates 2 and 3, result in a self-contained, defined position, so that it becomes a special position afterwards Adjustment of nozzle bores 8 with respect to the longitudinal gaps 25 and 26 is not required.
- a further advantage of the design of the system resulting from FIG. 2 is that the screws 37, 38, 39 and 40 required for the disassembly and assembly of the unit mentioned require an approach to the unit only from the side or from above, where there is normally enough space for the screws to turn.
- FIG. 2 shows the heating plates 19, 20 and 21 already mentioned in connection with the figure, which ensure the necessary heating of the nozzle package 1 with the air supply blocks 4 and 5.
- FIG. 3 shows an arrangement which, except for the design of the split plates, corresponds completely to the arrangement according to FIG. 2.
- the split plates 45 and 46 shown in FIG. 3 have a concave border on their side facing away from the air supply blocks 4 and 5 and the nozzle pack 1, so that air flowing past from the surroundings is uniform and largely without turbulence from the air flows emerging from the longitudinal gaps 25 and 26 is entrained, which largely avoids swirling of the filaments emerging from the nozzle bores 8.
