Definitions
- the invention relates to a nozzle blow box of a tenter frame for treating a textile fabric web that is spread out in its longitudinal direction, optionally consisting of at least two different types of nozzles with a treatment agent flow, the nozzles being provided in a blow-out surface that extends parallel to the fabric web surface, one that is movably mounted within the blow box Slider is provided for the selection of the desired nozzle type and the slider has through holes which open the path of the treatment agent flow through the one nozzle type in one slide position and through the other nozzle type in another slide position.
- the term “blow-out surface” is to be understood in general terms.
- the blow-out surface can contain the nozzles — as holes — or be designed as a holding means / framework for the nozzles.
- a nozzle design of this type is described in the German design specification 11 96 156 (DE 11 96 156 B1).
- the known nozzle design is intended for combined stenter-float driers with blow boxes, the distance from which is variable from the treated textile fabric.
- the blow-out surface of the respective blow boxes should consist of a first base plate, which has alternately larger and smaller discharge openings (nozzles) in one plane.
- a second floor panel also referred to as a slide, is to be displaceably mounted parallel (to the first floor panel), which only has the larger openings in the same pattern as the first floor panel.
- the slide is moved essentially transversely to the transport direction or transversely to the longitudinal direction of the fabric web being treated.
- the invention has for its object to provide for the blow-out surface of the blow box an adjustable or lockable spraying of the fabric web by the slide, which is guaranteed not to leave or produce stripes on the fabric web.
- the solution according to the invention is described in claim 1.
- the solution according to the invention preferably consists in the fact that in the blow-out surface a slot nozzle which extends transversely to the longitudinal direction over the width of the fabric web and which can also be referred to as a nozzle slot, as an outflow alternative that can be opened or blocked by the slide a plurality of perforated nozzles is provided.
- a slot nozzle which extends transversely to the longitudinal direction over the width of the fabric web and which can also be referred to as a nozzle slot, as an outflow alternative that can be opened or blocked by the slide a plurality of perforated nozzles is provided.
- the slider provided for switching the nozzles is movably supported transversely to the longitudinal direction of the fabric.
- other displacement directions are also possible within the scope of the invention, for example in the longitudinal direction of the fabric web or obliquely with respect to the longitudinal direction.
- the slide should basically release the treatment agent passage through one nozzle type in one position and through another nozzle type in another position.
- the slide should preferably be formed essentially in one piece. In the context of the invention, however, it can also be in two or more parts.
- a slide can consist of two parts, which between them, that is, between two mutually facing slide edges, either clamp (release) a slot nozzle or clamp (lock); at the same time, the slide parts should then either block or release the perforated nozzles to be switched (vice versa as with the slot).
- two or more than two nozzle types can be available for selection by the slide. Modifications are also possible with regard to the locking or opening of one or the other type of nozzle within the scope of the invention, for example different types of nozzles can be opened or blocked partially or completely at the same time.
- volume flow is the total flow that hits the web through the nozzles.
- the slides - and / or nozzle openings - should be designed in such a way that the instantaneous sum of the slot / hole opening degrees, for example the opening cross-sections, and thus the total of the currently open cross-sections cuts flowing volume flow practically does not change when switching. It is also within the scope of the invention to gradually or continuously change the volume flow when switching, for example to increase or decrease it.
- the outflow surface of the nozzle blow box with perforated nozzles and at least one slotted nozzle which extends across the entire width thereof across the web surface and to provide a slider with the aid of which it is possible to select between the perforated nozzles and the slotted nozzle in the manner described above.
- the hole / slot nozzle construction according to the invention does not have to be present everywhere in the stenter and / or be of the same design. Often it is sufficient to equip the outflow surfaces facing a sensitive side of the fabric surface with the nozzle combination at the end of the machine (seen in the direction of transport), for example in the last field of a tenter.
- the slot nozzles should extend across the entire width of the fabric. For technical reasons, it is often necessary to provide narrow crossbars in the slot nozzles, which mechanically stabilize the nozzle slot, which is sometimes three or more meters long. However, the webs which are transverse to the longitudinal direction of the nozzle slot should be made so thin that they practically do not impair the flow of treatment agent passing through the slot, at least not in a disturbing manner.
- a slot nozzle delivers a relatively low evaporation capacity compared to perforated nozzles. For this reason, a stenter or blow box should only be operated with a partially or fully open slot nozzle if this is unavoidable, for example due to the absence of streaks. It may even be favorable to blow the fabric web out of perforated and slit nozzles at the same time, so that the desired evaporation performance and the desired streak freedom or the like are achieved through the perforated nozzles.
- the invention makes it possible to meet the requirements of the individual Delten textile fabric webs according to the slide in the direction of the slot nozzle opening or in the direction of the perforated nozzle opening to a greater or lesser extent.
- blow-out surface with slide and nozzles various constructions are possible for the construction of the blow-out surface with slide and nozzles.
- a preferred embodiment of a slider to choose between slot and hole nozzle operation is that the slider, like the blow-out surface, has holes and at least one slit (which extends over the entire width of the web). However, for example, there should be a distance between the slot and the group of holes that differs by more than one slot width, such that the slider blocks the holes in one position and blocks the slot in another position.
- Such a slide for locking and opening a nozzle slot which extends transversely to the longitudinal direction of the fabric web is shifted in the longitudinal direction by at least one slot width (measured in the longitudinal direction of the fabric web) in order to change from slot to hole operation or vice versa.
- a slide is also possible, in which the distribution of holes and nozzle slot is provided (or congruently) as in the blow-out surface.
- an additional opening and closing mechanism for example a blind
- the construction can be designed in accordance with another invention in such a way that the nozzle slot is closed by the Venetian blind in a slider position, but the holes in the slider come to coincide with the holes in the blow-out surface, and in the other slide position the blind and thus the slot is open, but the holes in the blow-out surface are blocked (by the surface of the slide).
- the slot is - in Flow direction of the treatment agent - a switchable system according to the invention of through holes which are displaceable relative to one another by the slide movement, so that either the access of the treatment agent flow to the slot or the perforated nozzles can be blocked.
- the blow-out surface should have a nozzle slot extending in the adjustment direction of the slide as an outflow alternative to a plurality of perforated nozzles and a tunnel bridging the slot along its entire length toward the inside of the blow box with tunnel holes offset against the perforated nozzles, the latter connecting the (from the inside of the blow box) form to the slot.
- An additional advantage of this construction is that the treatment agent, when the access to the nozzle slot is open, is fed to it by way of advantageously angular tunnel holes, so that despite the use of the nozzle slot, a relatively high evaporation performance with no streaks is achieved.
- the slider (corresponding to the perforated nozzles) should have additional through holes in its area adjacent to the tunnel, which in a slider position are to be aligned with the tunnel holes and direct the flow of treatment agent through the tunnel holes and the slot nozzle.
- the slider should therefore have two types of through holes.
- One type of hole should be covered with the hole nozzles in a slide position and the other hole type should be covered with the tunnel holes in another slide position.
- part of the through holes of the slide should come to coincide with the hole nozzles in a slide position and another part of the through holes of the slide in another slide position with the tunnel holes.
- the invention makes it possible in the simplest possible way to use a tenter frame either in the perforated nozzle mode and in the slot nozzle mode.
- the switching of the tenter frame according to the invention makes it possible to quickly switch from one type of treatment to another and even to set intermediate positions, so that goods of different quality can be used quickly in succession one and the same machine must be treated without streaks and with optimal evaporation performance.
- Figure 1 shows a section transverse to the web transport direction through a tenter.
- Figures 2 and 3 show a section along the line A-A of Figure 1 for two different slide positions.
- 4 is a plan view of the blow-out surface; 5 to 8 show a section as in FIGS. 2 and 3 with a slide modification; and
- FIGS. 9 to 12 show a further modification of a slide showing different positions.
- a vertical section perpendicular to the longitudinal direction of a tenter is shown schematically.
- the textile fabric web 1 to be treated, held in chains 2 and 3 at its longitudinal edges is passed horizontally between two blow boxes 4 and 5 in its transport or longitudinal direction, that is, in the direction perpendicular to the plane of the drawing.
- One blow box namely the upper blow box 4
- the other blow box namely the blow box 5
- Each of the blow boxes has - parallel to the fabric sheet 1 - a blow-out surface 6 or 7, which serves to bring a treatment agent flow 9 accelerated with the aid of a fan 8 to the fabric web 1.
- partial streams 10 are directed from above onto the fabric web 1 from nozzles (not shown in detail in FIG. 1), while 5 partial streams 11 of the treatment agent stream 9 hit the fabric web 1 from below from the lower blow box.
- the partial streams 10, 11 are either reflected on the fabric web 1 or they flow through the web and then flow, for the play through (not shown) slots of the respective blow box 4, 5, as reverse flow 12, 13, often through a sieve 14 and a heat exchanger 15, back to the fan 8.
- FIG. 1 In practice, there are numerous more or less fundamental deviations from this basic structure according to FIG. 1 to which the invention can be applied.
- the actual invention namely a blow box optionally switchable to perforated nozzle and slot nozzle operation, is explained with reference to FIGS. 2 to 12.
- FIGS. 2 and 3 are to be seen as a section along the line A-A of Fig. 1 through part of the upper blow box 4 and through the fabric web 1.
- a blow box is assumed, the blow-out surface 6 of which has a plurality of perforated nozzles 17 and at least one slot nozzle 18.
- FIG. 4 shows a partial view of the blow-out surface 6 of an upper blow box 4 suitable for FIGS. 2 and 3.
- the longitudinal or transport direction 19 of the fabric web 1 is indicated by an arrow.
- the perforated nozzles 17 are arranged in rows 20 which are essentially parallel to the longitudinal direction 19 of the fabric web and transverse to the longitudinal extent of the slot nozzle 18.
- a tunnel 22 spanning the entire length of the slot nozzle 18 toward the interior of the blow box 21 is provided with tunnel holes 23 which form the connection to the slot nozzle 18 and transversely to the longitudinal direction 19 against the hole nozzles 17.
- a slide 24 which can be adjusted in the longitudinal direction 25 of the slot nozzle 18 relative to the blow-out surface 6 (displaceable parallel to it).
- the slider 24 has two types of through holes, namely through holes 26, which come into congruence with the hole nozzles 17 in a slider position (movement in the longitudinal direction of the slot 25), and through holes 27, which come into congruence with the tunnel holes 23 in a different slider position, that is to say open the tunnel holes 23 for the passage of the treatment agent flow 9.
- the hole nozzles 17 and the tunnel holes 23 are shown offset from one another in the longitudinal direction 25 of the slot, while the through holes 26, 27 of the slide 24 are each in a row (parallel to the longitudinal direction 19).
- the hole nozzles 20 and tunnel holes 23 can also be arranged in a row parallel to the longitudinal direction 19 and the through holes 26 and 27 correspondingly offset in the longitudinal direction 25 of the slot.
- the slide 24 should block the hole nozzles 17 in one of its longitudinal positions, but release the tunnel holes 23 for the flow of the treatment agent flow 9, and release the hole nozzles 17 in the other longitudinal position, but can block the tunnel holes 23.
- the treatment agent flow 9 flows through the tunnel holes 23 and the slot 17 in the direction of the fabric web 1.
- the treatment agent flow 9 also flows through the hole nozzles 17 onto the fabric web 1.
- FIGS. 5 and 6 also show a section along the line AA of FIG. 1, but with a modification of the slide 24 compared to FIGS. 2 and 3.
- perforated nozzles 17 are again an alternative to a slot nozzle 18.
- the slide consists of two parts 24a and 24b which can be displaced relative to one another with at least one component parallel to the longitudinal direction 19 of the fabric web to be treated, in order to open either the perforated nozzles 17 or the slot nozzle 18 for the passage of the respective treatment agent flow 9.
- an adjustment mechanism is provided for the two slide parts 24a and 24b, the functioning of which can be seen from FIGS. 7 and 8.
- Each slide part can have a bolt guide 28 which is inclined with respect to the longitudinal direction 19 and thus approximately diagonally to the longitudinal direction 19 of the fabric and the longitudinal direction 25 of the slot.
- a bolt 29 projects through each guide 28 and is fixed to the blow box 4. If the slide parts 24a and 24b are pulled or pushed relative to the bolts 29 in the slot direction 25 by any external activator, the mutually facing longitudinal edges 30, 31 of the slide parts 24a and 24b are pushed towards one another (FIG. 7) or pulled apart (FIG. 8th).
- the perforated nozzles 17 are provided (for example by means of the surface of the slide parts 24a, b see holes) opened and the slot 18 (by colliding or overlapping the longitudinal edges 30, 31) blocked, otherwise (Fig. 8) the hole nozzles 17 are blocked (for example by surface parts of the respective slide parts 24a, b) and the slot 18th open.
- FIGS. 9 to 12 Another exemplary embodiment of a mechanism for exchanging perforated nozzles 17 for a slot nozzle 18 and vice versa is shown in principle with reference to FIGS. 9 to 12.
- 4 flaps 32 are attached to swivel joints 33 above the slot 18 of the blow box.
- a slide 24 is provided for actuating the louver flaps 32, to which the louver flaps 32 are fastened in an articulated manner, for example with bearings 34, as shown.
- the swivel joints 33 can, for example, be supported on both sides of the slot 18 on the blow-out surface 6 of the blow box 4, so that the swivel axes are approximately transverse to the longitudinal direction 25 of the slot.
- the louvre flaps 32 are placed essentially perpendicular to the blow-out surface 6, so that the passage for the treatment agent flow 9 is cleared.
- 11 shows this position of the louver flaps 32 in a top view of the slot nozzle 18. If the slide 24 is pulled in the direction of arrow 25b according to FIG. 10, the louver flaps 32 are correspondingly placed flat on the blow-out surface 6 and thus on the slot 18, so that the latter is blocked according to FIG. 12 for the passage of the treatment agent flow 9.
- the outer blow-out surface 6 with the perforated nozzles 17 and the slot nozzle 18 could also be designed to be displaceable in the direction of arrow 25 with the through-holes 26 and 27 - that is, the slide and the blow-out surface could be replaced - become.
- the invention is described for a tenter frame with a fabric web 1 stretched transversely to the longitudinal or transport direction 19 with the aid of chains 2, 3.
- a floating dryer with or without chains or transverse tension can also be used.
- the invention is also applicable to a dryer which has a blow box 4 or 5 only above or only below the fabric web 1.
- the fabric can also be carried through the treatment zone with the help of a screen belt.
