Definitions
- the invention relates to a slot nozzle for coating material webs, in particular paper or cardboard webs with pigment coating color, with a slot-shaped outlet channel which extends over the working width and a distribution chamber which extends over the working width and to which the outlet channel is connected.
- slit nozzles extending across the working width are known to be used in order to apply a defined curtain or jet of coating material to the web.
- the slot nozzle is arranged above the web and extends transversely to the web running direction. The coating material emerges from the nozzle in a free-falling curtain and falls onto the web.
- Such a slot nozzle of the generic type is known in EP 0 327 020-B1 in a coating device which is used for the production of photographic films.
- the invention is therefore based on the object to improve a generic slot nozzle so that it is able to on paper or cardboard webs with a large width also small amounts of pigment coating under fluctuating conditions, eg. B. fluctuating viscosity or changing order quantities, apply evenly over the working width without problems.
- the slot nozzle according to the invention offers the possibility of influencing the flow conditions in the distribution chamber over the working width via the volume flows supplied.
- connection of a feed channel to the distribution chamber as a diffuser according to claim 3 has the effect that the flow rate decreases significantly when entering the distribution chamber. This prevents the coating color from detaching from the walls and thus vortices that would lead to uneven flow conditions.
- Diffusers connected to the distributor chamber inclined make it possible to use long diffusers with a low overall height and to connect them to feed channels which are supplied in a substantially straight line from one side. Since the coating color is conveyed at a high flow rate within the feed channels, curvatures in the feed channels could lead to undesired separation effects in the case of sensitive coating colors.
- Figure 1 shows a longitudinal section through a slot nozzle according to the invention.
- Figure 2 shows a cross section along the line A-A of Figure 1.
- Figure 3 shows a cross section along the line B-B of Figure 1.
- FIG. 4 shows a top view of the exit gap from below.
- FIG. 5 shows in cross section the structure and operation of a slot nozzle when used as a curtain nozzle.
- FIG. 6 shows, roughly schematically, a particularly simple construction of a slot nozzle with cooling elements on the long sides.
- FIG. 7 shows a roughly schematic cross section of a slot nozzle with a second distributor chamber which is arranged in a climatic chamber.
- Figure 8 shows the cross section of an alternative embodiment of a slot nozzle, which is designed as a free jet nozzle.
- the nozzles shown in the figures are used to apply pigment coating ink to a paper or cardboard web B.
- the pigment coating ink is either applied directly to the paper or cardboard web B or first to a roller, which then transfers the film of coating color to the web B.
- the slot nozzle is used either as a curtain nozzle or as a free jet nozzle. When used as a curtain nozzle, it is arranged above the web B and extends across the working width, and the coating color emerges from it in a free-falling curtain V.
- a curtain nozzle When used as a curtain nozzle, it is arranged above the web B and extends across the working width, and the coating color emerges from it in a free-falling curtain V.
- a free jet S of coating color emerges from the slot nozzle under pressure, which is directed directly against the web B or — in the case of indirect application — against a roller.
- the free jet nozzle is arranged in relation to the web B to be coated or the tangent to the roller to be coated such that the liquid jet S impinges at an acute angle to the direction of movement of the web B or roller.
- the nozzle body of the slot nozzle consists of two wall-shaped parts 1, 2 with a length corresponding to the desired working width.
- a longitudinal groove is machined, which forms a distributor chamber 3 after the two parts 1, 2 have been joined together.
- the two parts 1, 2 each have plane-ground inner surfaces with which they are joined and held together by means of fastening screws 4.
- One of the two transverse walls delimiting the distributor chamber 3 - the lower transverse wall 5 in FIGS. 2 and 3 - is designed with a somewhat lower height than the other, upper transverse wall 6, so that a distance to the wall part 2 remains in this area when being assembled to form a slot-shaped outlet channel 7, which extends over the working width, which is connected to the distributor chamber 3 and from which the coating color emerges.
- the outlet channel 7 is limited on the one hand by the inner surface of the wall part 2 and on the other hand by an inserted strip 8 which is screwed onto the inner surface of the lower transverse wall 5 by means of screws 9 .
- the insert strip 8 has below the fastening screw 9 on its side facing away from the outlet gap 7
- the lower part of the insert bar 8 has the distance from the inner surface of the transverse wall 5 which is necessary for the required adjustment path.
- the gap width of the outlet channel 7 is adjusted by means of wedges 11 arranged at regular intervals over the working width and parallel in a longitudinal groove in the lower transverse wall 5 are arranged movably to the outlet channel 7 and support the insert strip 8 on its rear side.
- the wedges 1 1 thus define the distance of the insert strip 8 from the wall part 2 and thus the gap width of the outlet channel 7 in its area.
- the position of each wedge 1 1 is adjusted by means of an adjusting screw 1 2
- clamping screws 13 are arranged in the area between two wedges 11, of which the insert bar 8 can be clamped against the wedges 11 and thus against the transverse wall 5.
- Feather keys 14 between the transverse wall 5 and the upper region of the insert bar 8 prevent one Shift of the insert bar 8 parallel to the outlet channel 7 when setting the gap width.
- the inner surfaces of the transverse wall 5 and the insert strip 8, from which the lower boundary wall of the distributor chamber 3 is formed, are designed to be flush with one another and inclined in the direction of the outlet channel 7, so that the coating color is guided to the outlet channel 7.
- the width of the outlet channel 7 is set to a value between 150 ⁇ m and 600 ⁇ m, preferably between 250 ⁇ m and 350 ⁇ m.
- the width of the outlet channel is 7 700 ⁇ m to 1 300 ⁇ m.
- the height of the distribution chamber 3 measured parallel to the outlet channel 7 is 10 mm to 100 mm, preferably 20 mm to 60 mm. If the height is more than 20 mm, its width is less than its height. As a free jet nozzle, the height of the distribution chamber 3 is 40 mm to 1 50 mm. The width is preferably between 50% and 60% of the height.
- the upper transverse wall 6 of part 1 has inlet openings 1 5 at regular intervals, to which, as shown in FIG. 5, feed channels 1 6 for supplying coating color into the distribution chamber 3 are connected.
- feed channels 1 6 for supplying coating color into the distribution chamber 3 are connected. The so connected to the distribution chamber 3 on the side opposite the outlet channel 7
- Feed channels 1 6 have a connection distance between 100 mm and 1 500 mm, preferably between 500 mm and 800 mm.
- the connection of each feed channel 16 to the distributor chamber 3 is preferably designed as a diffuser, so that the flow velocity drops when entering the distributor chamber 3 due to the increasing flow cross section.
- the diffusers are each from the
- Opening 1 5 is formed in the transverse wall 5 and a screwed-on diffuser part 1 7, to each of which a feed channel 1 6 is attached.
- the diffusers formed by the openings 15 and the diffuser part 17 are preferably designed and arranged in such a way that they are connected to the distribution chamber 3 at an angle to the lateral edge against the vertical.
- the connection of the diffusers which is preferably inclined to one side - that is to say with parallel feed channels 16 - is carried out in such a way that a boundary wall (the left one in FIG. 1) Boundary wall) at an angle ⁇ between 0 ° and 90 °, preferably between 30 ° and 60 ° is connected to the upper boundary wall of the distributor chamber 3, the opposite boundary wall of the diffuser at an angle ⁇ between 10 ° and 45 °.
- the boundary wall of the diffuser on the feed side immediately before the connection to the distributor chamber 3 is additionally curved outwards in order to further enlarge the cross section and to make the radius of the deflection as large as possible. In the exemplary embodiment, this is brought about by a corresponding curvature of the inlet-side wall 18 of the inlet opening 15 that forms the last part of the diffuser.
- the boundary wall 18 of the diffuser designed in this way prevents the coating color from detaching from the walls and thus vortices which would cause the coating color to separate.
- the slot nozzle is closed by side plates 1 9.
- a downwardly extending guide element 20 is arranged on each side directly next to the outlet channel 7, which counteracts a constriction of the curtain V falling from the outlet channel 7 of coating color.
- a partial stream of coating color as contact liquid is let down on the inner surface of each guide element 20 and is supplied via a supply channel 21.
- each feed channel 16 has a device 22 for adjusting the volume flow.
- hose clamp valves are preferably used for the volume flow setting. Alternatively, the use of
- each feed channel contains a measuring device 23 for determining the current volume flow so that it can be regulated individually; z. B. inductive or ultrasonic volume flow meters 23rd
- FIG 6 an embodiment of a nozzle is shown schematically, which is structurally particularly simple. This structure is useful if there are no control elements Cross profile control are required, so the width of the outlet channel 7 does not have to be adjustable differently over the working width.
- the nozzle body is composed of two parts 1, 2, each of which has a flat-ground inner surface.
- the distribution chamber 3 is incorporated as a longitudinal groove.
- the inner surfaces of the two transverse walls 5, 6 are designed in alignment.
- FIG. 7 shows an embodiment with a second distributor chamber 25 arranged between the first distributor chamber 3 and the outlet duct 7. Between the first distributor chamber 3 and the second distributor chamber 25 there is an additional flow duct 26 which brings about a further equalization of the flow.
- a row of heating or cooling elements 27 is arranged on one or on both longitudinal walls of the nozzle body of the slot nozzle, as shown in FIG.
- the heating or cooling elements 27, for example Peltier elements, resistance wires etc., are arranged at a distance of 100 mm and more over the working width, and their heating or cooling output can be regulated individually in order to be able to act in a targeted manner on individual areas.
- FIG. 8 shows the cross section of a slot nozzle when used as a free jet nozzle, by means of which the coating color is applied to a paper or cardboard web B supported by a counter roller 30.
- the slot nozzle has a slot-shaped outlet channel 7 which extends over the working width.
- the slot-shaped outlet channel 7 is delimited by two lips 31, 32, one of which - in the exemplary embodiment the lip 31 on the outlet side - can be adjusted differently in zones by means of a series of adjusting elements 33 in order to set a uniform transverse profile.
- the width of the outlet channel 7 is set to the aforementioned 700 ⁇ m - 1 300 ⁇ m.
- the distribution chamber 3 is delimited by two side walls 1, 2, which are screwed on the inlet side to a transverse wall 34 by means of screws 35, from which they are kept at the distance desired for the chamber width.
- One side of the lips 31, 32 is attached to each side wall 1, 2 on the outlet side.
- the structure of the free jet nozzle essentially corresponds to the slot nozzle shown in FIGS. 1 and 5: at least two feed channels 16 are likewise connected to the distributor chamber 3, each of which has a device for adjusting the volume flow.
- the connection distance of the feed channels 16 is also 100 mm to 1500 mm, preferably 500 mm to 800 mm.
- the connection of a feed channel 16 to the distributor chamber 3 is designed as a diffuser, the diffusers being connected to the distributor chamber 3 inclined in the direction of the lateral edge at the angles described in the exemplary embodiment according to FIGS. 1 to 5.
