Definitions

  • the invention relates to a device for applying a thin layer of a coating material to a web of material running over a counter-pressure roller by means of a slot nozzle device with a fixed inlet and outlet nozzle lip of the nozzle slot, in particular a wide nozzle slot, in which the outlet nozzle lip is designed as a rotatable doctor rod in a two-part doctor blade bearing .
  • US Pat. No. 3,919,974 discloses a slot nozzle device with fixed nozzle lips of the nozzle slot, in which the nozzle lips can be adjusted relative to one another to adjust the nozzle slot.
  • Such a slot nozzle device requires the use of counter-pressure rollers with a length that is precisely adapted to the coating width and material web width. There is no provision for self-cleaning of the nozzle lips in order to achieve the most coating-free application of the coating material.
  • a coating device has become known from US Pat. No. 2,946,307, in which the coating material is either applied to the material web to be coated via a scoop roller and then scraped off by means of a doctor blade, or is applied in a sump between the material web running over a guide roller and the doctor blade becomes.
  • the advantages of a slot . Nozzle application can not be achieved with such a device.
  • a device of the type described in the introduction is known from DE-OS 1 964 908.
  • One of the two squeegee bearing parts is formed there by a cleaning spatula resting on the squeegee rod with a variable contact pressure.
  • the length of the counter-pressure roller must be set exactly to the width of the material web in order to avoid contamination of the counter-pressure roller outside the coating width and rubbing of the running nozzle lip on the counter-pressure roller without an intermediate material web.
  • the invention has for its object to provide a device of the type described above, which makes the use or replacement of special counter-pressure rollers for different web widths superfluous and ensures practically days of coating agent free ends of the counter-pressure roller even with longer production times.
  • doctor rod outside the web width is provided with segment-shaped recesses and is driven in such an oscillating manner that the segment-shaped recesses cannot come into connection with the slots between the two doctor blade bearing parts.
  • This design of the running nozzle lip or the doctor rod ensures that the doctor rod is sufficiently lubricated in its storage by the coating material, but that no coating material can escape into the area outside the intended coating width and thus beyond the material web width onto the counter-pressure roller.
  • the doctor rod can be produced and exchanged in a simple manner for any desired coating and web width.
  • the doctor rod is advantageously firmly connected to a linkage, which in turn is easily releasably connected to a drive for the doctor rod.
  • sealing strips are expediently inserted in the nozzle slot in the area outside the web width.
  • the doctor bar advantageously has a plurality of segment-shaped recesses along its length, in each case at the points where the counter roll is not covered by a material web to be coated.
  • the doctor rod can be made of steel and the counter-pressure roller can be coated with an elastic material such as hard rubber, rubber and the like.
  • the hard rubber doctor rod and the counter-pressure roller can be a chrome-plated steel roller.
  • the two squeegee bearing parts are expedient for the simple and precise production of the running nozzle lip screwed together and fixed in position to each other by means of conical pins.
  • the doctor rod can also be designed as a spiral doctor.
  • the running-off nozzle lip with a doctor blade rod is expediently adjustable as a flexible nozzle lip by means of tension and compression screws in its line of contact with the material web and the counter-pressure roller. This makes it easy to set a uniform distribution of the coating thickness.
  • a flow inhibitor strip which can be adjusted in the nozzle body part of the doctor rod and is adjustable by means of tension and compression screws can be provided in the feed line to the slot nozzle.
  • the slot nozzle device is expediently installed laterally next to the counter-pressure roller and is rotatable.
  • the incoming nozzle lip of the slot nozzle designed as a slot die is advantageously designed as a sealing lip.
  • the counter-pressure roller can always remain unchanged in the device, while due to the special design of the running nozzle lip with a doctor bar and the design and drive of this doctor bar, both a leakage of coating material outside of the material web to be coated and also 0 a contact of the running nozzle lip in the form of the doctor rod with the counter-pressure roller outside the material web to be coated is reliably avoided. This is particularly important in the case of thin layers on the order of 1 to 40 g / m 2 .
  • the device according to the invention for applying a thin layer of a coating material has a counter-pressure roller 1, which is covered with rubber or hard rubber.
  • a material web 2 to be coated with a web width a is guided over the counter-pressure roller 1 in the direction of arrow A.
  • the coating width b is smaller than the web width, while the width c of the counter-pressure roller 1 is larger than the web width a.
  • a slot nozzle device 3 On one side of the counter-pressure roller 1 there is a slot nozzle device 3 with a fixed inlet and outlet nozzle lip of the nozzle slot.
  • the width of the slot nozzle is denoted by d.
  • End plates 4 are provided on both end faces of the slot nozzle device.
  • Material webs 2 to be coated are, for example, paper webs, plastic films, metal foils, fabric webs and combinations of such material webs.
  • the material web 2 can be an aluminum foil with a thickness of 0.008 mm, 0.012 mm, 0.02 mm and up to 0.12 mm.
  • smooth, coated or creped papers from 40 to 120 g / m 2 are possible
  • plastic films polyethylene films from 40 to 120 mg thickness, biaxially oriented, so-called oriented polypropylene films from 30 to 120 m ⁇ thickness and polyester films in the same thickness range.
  • two hard PVC films and monomeric and polymer-softened PVC films can be processed as material webs, and, for example, carpet laying tapes and dressing materials as fabric webs.
  • Coating materials include paraffins and microcrystalline waxes with processing temperatures between 75 ° C and 100 ° C with application quantities between 4 and 40 g / m 2 .
  • Coating hotmelts consisting of ethyl vinyl acetate copolymers, mixed with paraffin and resins, are also suitable at processing temperatures between 140 ° C and 190 ° C for the surface finishing of packaging material.
  • Hot melt pressure sensitive adhesives used have processing temperatures between 140 ° C and 190 ° C with application quantities between 12 and 40 g / m 2 , while thermoset adhesives are processed at temperatures from 70 ° C to 80 ° C and application quantities from 40 g / m 2 .
  • Polyurethane adhesives consisting of two components, are mixed shortly before coating.
  • Further coating materials are aqueous emulsions and dispersions as PVDC coatings at room temperature, acrylate adhesives as aqueous dispersions with coatings also at room temperature, various starch adhesives, that are processed at temperatures from 70 ° C to 90 ° C, adhesives and coating compounds that are dissolved in organic solvents and processed at room temperature and finally cold glue PVC based on polyvinyl alcohol.
  • the incoming nozzle lip 5 of the slot nozzle device 3 is designed to be stationary.
  • the running-off nozzle lip of the slot nozzle is designed as a rotatable doctor rod 6.
  • the doctor rod 6 has, outside the web width a, segment-shaped recesses 7 which extend beyond the roller width c and through which the doctor rod 6 is offset like a key surface.
  • the slots 8 between two doctor blade bearing parts 9 and 10, which are inevitable for the manufacture of the doctor blade support, are constantly closed by the doctor blade rod 6.
  • the slot nozzle device 3 is supplied with coating material via a coating material channel 11.
  • the coating material channel 11 is located at the separation point between an upper nozzle half 12 and a lower nozzle half 13.
  • Heating or cooling bores 14 are provided in the nozzle halves 12 and 13.
  • the doctor rod 6 which forms the running nozzle lip is driven in an oscillating manner via a gear motor 15, a connecting rod 16 and a linkage 17 which is fixedly connected to the doctor rod 6 in such a way that the doctor rod 6 would stand on the one hand dig seals the slots 8 between the two squeegee bearing parts 9 and 10, but on the other hand, due to its segment-shaped recesses 7 outside the material web 2, it cannot come into contact with the counter-pressure roller 1. This reliably prevents damage to the counter-pressure roller 1 by the doctor rod 6, while at the same time ensuring that no coating material can escape onto the counter-pressure roller 1.
  • the connecting rod 16 can be easily detached from the linkage 17, whereupon the doctor rod 6 can simply be pulled out of the doctor bearing and replaced by a doctor rod adapted to a changed web width a.
  • the geared motor 15 has a rotational speed of 9 to 11 revolutions per minute and results in a correspondingly oscillating movement of the doctor rod 6, as a result of which the doctor effect for the running nozzle lip is achieved and thus streaking during coating is reliably avoided.
  • the slot nozzle device 3 can be rotated by a rotary mechanism, not shown, in such a way that the fixed incoming nozzle lip 5 lies lightly against the material web 2 and achieves a sealing effect, so that no coating material runs out downwards and still no appreciable friction between the protruding ends of the counter-pressure roller 1 and the nozzle lip 5 is formed.
  • the fixed incoming nozzle lip 5 is screwed to the lower nozzle half 13 and has a baffle 18.
  • the structure of the running-off nozzle lip can best be seen from FIG. 3.
  • the doctor rod 6 is in two parts Doctor blade bearings stored.
  • the squeegee bearing part 9 is screwed to the squeegee bearing part 10 by means of a clamping bar 19 and clamping screws 20.
  • the doctor bearing part 9 is first slightly tightened with the tensioning screws 20. Thereafter, the distance between the squeegee bearing part 9 and the squeegee bearing part 10 is adjusted by tapping lightly with a plastic hammer so that a cylindrically ground pin with a length of approximately 30 mm and 12 mm diameter, fit h 6 can be pushed through the entire bore length.
  • the clamping screws 20 are now tightened.
  • squeegee bearing part 9 There are pre-drilled holes in the squeegee bearing part 9 between the clamping screws 20 of the squeegee bearing part 9 which is designed as a clamping strip and which are arranged approximately at a distance of 100 mm. After the final adjustment has taken place, these predrilled holes are further drilled out and driven into the doctor bearing part 10. With a conical machine reamer, the holes are expanded in such a way that conical pins 21 with withdrawal threads 22 reproducibly position the squeegee bearing part 9 and the squeegee bearing part 10 in the set position.
  • the squeegee bearing part 9 can be dismantled as often as required for cleaning purposes after pulling off the conical pins 21 and after loosening the clamping screws 20.
  • the doctor rod 6 together with its doctor bearing 9, 10 can be moved under tension by means of tension and compression screws 23 for clamping sealing strips 24 in the feed slot 25 to the nozzle, which limit the nozzle slot to the coating width.
  • Tension and compression screws 26 are provided for influencing the coating profile.
  • the doctor rod 6 is held with the help of the two doctor bearing parts 9, 10 over 3/4 of its circumference, so that its position and shape remains adapted during its oscillating movement of the bore, which is provided with a fit seat H 7 .
  • the doctor rod 6 itself is manufactured with a h 6 fit. A limited play occurs between the bore and the doctor rod 6, which is why coating material can also enter the doctor rod bearing, which serves as lubrication, but can accumulate in the longitudinal direction along the slot 8 between the two doctor bearing parts 9 and 10 up to the end plates 4 of the slot nozzle .
  • the recesses 7 provided at the points described above ensure the contactlessness of the counter-pressure roller 1 without a superimposed material web 2 and the sealing of the slot 8 over the entire length of the doctor blade.
  • the running nozzle lip in the form of the doctor rod 6 with the associated doctor bearing is designed as a flexible nozzle lip.
  • a further element for influencing the coating distribution is a flow restricting strip 27 in the feed channel 11 to the slot nozzle.
  • This flow restricting strip 27 can be adjusted by means of tension and compression screws 28 such that the flow distribution of the coating material is influenced over the web width.
  • the flow restricting strip 27, also called choker bar, is mainly used for highly viscous compositions.
  • coating materials can be processed in a viscosity range from that of water to 25,000 poise.
  • the application weights are between 1 and 4 00 g / m 2 .
  • the doctor rod 6 is usually made of steel, while the counter-pressure roller 1 is coated with rubber; the counter-pressure roller 1 can also be a chrome-plated steel roller. Alternatively, the doctor rod 6 can be made of hard rubber and the counter-pressure roller 1 can be a chrome-plated steel roller, which is ground with the highest precision.
  • the concentricity should be 0.001 to 0.003 mm. These accuracies are necessary because the best possible distribution of the coating is sought. At 25 g / m 2 dry weight application, the fluctuations should not be more than - 1.5 g / m 2 ; 1 g / m 2 coating mass corresponds to a specific weight of 0.9 approximately 0.001 mm thickness of the coatings.
  • doctor blades are used as the doctor rod.
  • the coating weight is then determined by the wire thickness of the spiral doctor.
  • Stainless piano side wires can be wound around the squeegee bar 6 in one or more threads.
  • the coating material is pressed through each other through the resulting gaps between the wires.
  • the coating has fine lines, which are not always desirable. If a spiral doctor blade is used as the doctor rod 6, the windings located in the doctor bearing must be sealed so that the coating material cannot run around the doctor rod 6 and settles on the material web 2 above the doctor rod 6.
  • the semicircular hole in the squeegee bearing part 10 is first milled and then ground with a form grinding wheel.
  • the bore section on the squeegee bearing part 9 is produced in a similar manner.
  • the squeegee bearing part 9 is adjusted in height so that it forms part of a circle together with the semicircular bore.
  • the hole is dipped in using cylindrical ground pins.
  • the final setting is made after the nozzle lip and doctor bearing part 9 are ionized to a surface hardness of 1,000 to 1,200 Vickers.
