Definitions
- the present invention relates to a device for drying of a printed material, and more particularly to a device using a drying fluid propelled towards the printed material through nozzles.
- the material printed in the form of sheets or strips passes through a drying device comprising a box in which are placed a series of nozzles through which a drying fluid, usually air heated, is propelled on the printed face of the printed material.
- a drying fluid usually air heated
- This air heated after being in contact with the printed material, is then extracted from the suction dryer cabinet.
- the heated air is blown towards the printed part of the material printed by nozzles placed perpendicular to the plane defined by the material in strip or sheet.
- the movement of the printed matter moving at high speed causes a laminar current in the vicinity of its surface somewhat isolating the printed layer from the ambient air of the dryer.
- a solution to facilitate the access of the air blown by the nozzles to the printed layer consists in destroying the laminar current by causing turbulence neighborhood of it.
- Such a solution is implemented by the subject of the patent US4,779,555 in which the heated air, blown in the direction of the material printed by a nozzle, is then returned by said printed material in direction of several deflectors, placed in the vicinity of the nozzle, so as to cause a turbulence effect in the laminar current existing at vicinity of the printed surface.
- this device has the disadvantage of requiring the combination of nozzles and deflectors to create a current turbulent in the vicinity of the printed surface of the printed material.
- This combination has the further disadvantage of not creating a current continuous turbulent near the printed material due to the fact that at the location of the nozzle, more particularly at the right of the latter, the flow of blowing air which will come into contact with the strip material or in sheet will have laminar characteristics.
- the object of the present invention is to provide a device for drying of printed, strip or sheet, construction material simple, using simple nozzles that are not associated with deflectors complementary.
- Figure 1 is a schematic sectional view of a device for drying according to the state of the art in which the printed material 1 is moves in a chamber 2 a drying device in front of nozzles 3 having two blowing holes 4, 5.
- Each of the blowing holes 4, 5 is associated with series of deflectors 6, 7.
- the current drying fluid laminar 8 emerging from the blowing orifices 4.5 is propelled towards the material printed by a nozzle 3, then it is then returned by the surface of the printed material 1 in the direction of several deflectors 6, 7, placed at the neighborhood of nozzle 3, so as to cause a turbulence effect in the laminar current existing in the vicinity of the printed surface.
- This fluid turbulent drying 9 arrives on the printed material 1 and will destroy the laminar characteristic of the current in the vicinity of the surface of the printed matter 1 so that the drying fluid can mix with solvents emanating from the ink deposited on the printed material and increase by this eliminates the solvents present on this printed material.
- the mixture 10 of drying fluid and solvents will then be drawn into a drain 11.
- FIG 2 is a schematic view, in partial section, of a conventional drying device 12 through which a material passes printed 13.
- This drying device comprises an enclosure 14 in which nozzles 15 are arranged for blowing a heated drying fluid by heating bodies 16.
- the circulation of the drying fluid is represented by the arrows 17.
- the drying is sucked in via an evacuation pipe 18 using a first suction means 19 which could, for example be in the form of a fan.
- Part 20 of the mixture of drying fluid and solvents is discharged through a pipe 21, connected to a second suction means (not shown), while another part 22 of this mixture is recycled in enclosure 14 (see Figure 3).
- FIG 3 is a schematic view, in partial section, along III-III of figure 2 in which the same reference figures have been used to designate the different elements of the drying device. It will be noted that, in this version of the drying device, the evacuation drying fluid loaded with solvents is carried out through the center of the device, and that the flow of this drying fluid acts indirectly on the printed face of the material printed via its other face, which can be possibly not printed.
- FIG. 4 is a sectional view showing an arrangement nozzles 15 of the drying device 12 possible.
- Each of these nozzles 15 is equipped with means 23 for transforming the flow of the drying fluid which is laminar in nozzle 15 and which will become turbulent immediately at the outlet of nozzle 15.
- This turbulent flow is represented by the sign of reference 28.
- the printed material 13 consists of a support 24, usually cardboard or any material that can receive a coating ink 25 loaded with solvents.
- the printed material 13 moves at great speed speed in the direction indicated by arrow 26 causing an air layer laminar 27 which should be broken to ensure easier evacuation of the solvent and thereby efficient drying.
- the mixture consisting of the drying and by the solvents, represented in 32, will then be vacuumed by a exhaust pipe 29 placed between two successive nozzles 15.
- This exhaust pipe 29 can be constituted by a simple tube.
- the location of the exhaust pipe 29 is chosen preferably at equal distance from each of the two successive nozzles 15. It's obvious that one could choose to place this exhaust pipe 29 at any what distance from each of the nozzles 15.
- the orifices 30 of the nozzles 15 are have the form of a slot extending over the entire length of the nozzles 15.
- the exhaust manifold 29 has an opening 31 which also extends along the length of the exhaust manifold 29 corresponding to the length of the nozzles 15.
- Figure 5 is a sectional view of a nozzle 15 of the device drying 12.
- the orifice 30 of the nozzle 15 is provided with a mechanical means 23 for transformation of the flow of the drying fluid flow.
- the crenellated structure 33 is arranged parallel to the downstream face, with respect to the direction of displacement 26 of the printed material, from the end of the orifice 30, it is say parallel to the direction of passage of the drying fluid in the nozzle 15 (see figure 4).
- the nozzles 15 are arranged perpendicularly by relative to the surface of the printed material 13 and close to this surface. An inclined arrangement of the nozzles 15 relative to the surface of the material print 13 can also be considered. Obviously, the invention is not not limited to this example. At the limit and if necessary, each end of the orifices 30 of the nozzles 15 could be fitted with two crenellated structures 33.
- Figure 6 is a perspective view of an embodiment of one of drying device nozzles.
- the orifice 30 of the nozzle 15 is equipped with a mechanical means 23 for transforming the flow of the fluid flow from drying.
- the mechanical means 23 for transforming the flow of the flow of drying fluid is, in the figure shown, perpendicular to the circulation drying fluid through the orifice 30 of the nozzle 15.
- the means 23 transformation mechanics could also be parallel to the circulation of the drying fluid through the orifice 30 of the nozzle 15 (see Figure 4)
