Definitions

  • the invention relates to an application unit for viscous application materials, in particular solvent-containing and solvent-free UV printing inks, lacquers or adhesives on an anilox roller of a flexographic printing unit, which takes up the application materials in pans and delivers them to a printing roller.
  • the invention relates to a doctor blade configuration for such a flexographic printing unit.
  • a flexographic printing unit which is used, for example, for printing web-shaped printing material such as paper, plastic or the like, that gas or air bubbles develop in the application medium before application to an anilox roller, which, however, are used to produce a perfect print are to be avoided at all costs.
  • a low viscosity solvent-flexo paint tends to defoam, which is supported in the paint container in particular by stirring and a correspondingly large selected surface.
  • the object on which the invention is based is to design a commissioned work of the type outlined at the outset in such a way that, in order to achieve high print quality, the occurrence of air bubbles in the application media is effectively prevented without having to use technically complex means.
  • a housing adapted to the length of the anilox roller and a metering roller and its partial circumference is provided above the contact line between the metering roller and the anilox roller, which surrounds a chamber located above the contact line for receiving the application material and all of them Seals tightly.
  • the main advantage of this embodiment of the applicator according to the invention is that it allows a thin film of the application medium, in particular a thin ink film on the metering roller and this ink film together with the surface of the metering roller presses the air out of the at least partially empty cups of the anilox roller.
  • the wells which have already been filled are then immersed in the color supply of the chamber, so that foam and blistering in the chamber supply are excluded.
  • a ventilation device can also be provided in the upper chamber area. Furthermore, it is possible to completely dispense with a so-called dip roller.
  • the anilox roller 1 has cups (not shown) on its circumference, which receive an application medium, in the exemplary embodiment shown a printing ink, and deliver it to a high-pressure roller (also not shown).
  • the anilox roller 1 is one with a ceramic surface and laser engraving in order to transfer the ink to the high-pressure roller. With such a laser engraving, well grids can be produced with a well depth that can be less than 15 ⁇ m.
  • the metering roller 2 has a lateral surface made of rubber and is therefore elastic within certain limits.
  • the metering roller 2 can also have a hard surface, which suitably consists of ceramic, anodized aluminum, chrome, steel and the like.
  • the hard surface is advantageously provided with a grid by means of a laser beam treatment. This grid can have the desired shapes, in particular is in the form of a spiral.
  • Both rollers are driven independently of one another, the drive speeds being the same. Of course, it is possible to set the separate drives for the two rollers so that, for example, the metering roller 2 at a higher speed or at a lower speed than the anilox roller 1 is rotated.
  • the two rollers touch in the area of the contact line 4 in a line or slightly flat manner. Above this contact line 4 there is a chamber 6 for receiving the ink to be transferred to the high-pressure roller, as shown in FIG. 2.
  • This chamber is enclosed by the housing 5 with its doctor blade arrangement on the one hand and by the circumference of the rollers 1, 2 adjacent to it on the other hand in such a way that an air entry into the chamber causing bubbles in the application material is not possible.
  • the housing 5 of the squeegee configuration for closing this chamber 6 from the environment essentially comprises a plate made of aluminum profile and can be connected to a temperature control medium, preferably water, with the aid of openings 21 and 22, so that the housing and thus its surroundings are at the desired level Temperature can be brought and thus the temperature of the color can be influenced.
  • This color is added to the chamber 6 via a feed 19 and drawn off from the housing by means of a discharge 20.
  • the inflow and outflow of the paint into the chamber 6 takes place continuously or intermittently via a pumping station, not shown, according to the paint to be refilled or to be dosed.
  • the aluminum profile plate 8 of the housing 5 has interconnected or non-connected channels 23, 24, which are used so that in particular cold or hot water can flow through the housing as a temperature control medium.
  • the supplied by means of a pump, not shown Water flows into the housing 5 via an inlet 21 and leaves it via an outlet 22.
  • the two longitudinal edges 9, 10 of the plate 8 of the housing 5 have a doctor blade 11 and a doctor rod 12. Both doctor blades touch the associated roller 1 or 2 over their entire length. While the doctor blade is shown in FIG. 2, it is also possible to provide two doctor blades of this type. It is essential that the doctor blade 11 has a positive or a negative angle of attack with respect to the anilox roller 1, which is adjustable by means of an adjusting screw 7.
  • the doctor rod is in a doctor blade replaced the shape of a knife made of hard plastic or steel, which is placed obliquely against the metering roller opposite to its direction of rotation, thus contacting the latter including a negative angle.
  • the doctor blade pressure on the metering roller can also be changed here.
  • the two end plates 13 and 14 arranged on the end of the metering roller 2 and fastened to the housing 5 provide, in addition to a seal 17 '(FIG. 2) made of an elastic sealing material for the lateral limitation of the chamber 6.
  • the two end plates 13, 14 are each attached to a posture not shown in such a way that the applicator as such can be pivoted away from the rollers for maintenance or cleaning or can be removed entirely.
  • an actuating axis 127 is provided on the housing 5, by means of which the application mechanism can be adjusted continuously against the rollers 1, 2 in a substantially vertical direction.
  • An adjusting device (not shown) also ensures that the housing can be adjusted in a direction parallel to the plane of the roller axes.
  • the metering roller 2 can be driven with its rubber layer 3 or with a hard surface layer with the same, slower and faster running speed than the anilox roller 1, for example depending on the shape of the cup of the anilox roller 1 and the viscosity of the ink applied to the anilox roller .
  • the Shore hardness setting of the metering roller is equal to or less than that of the high-pressure cylinder.
  • the metering roller can be driven in that it is designed as a hollow body and has on the inner wall a circumferential toothing with which the external teeth of a pinion arranged within the metering roller mesh. Since the possible further drive options of the anilox roller 1 and the metering roller 2 are known as such, a detailed explanation of this drive is unnecessary.
  • the two rollers 1 and 2 rotate in the direction of the arrow according to FIG. 2.
  • the surface leaving the doctor rod 12 is the Dosing roller 2 has a color film which can be influenced by the doctor blade pressure and which, together with the rubber coating 3 of the metering roller when it comes into contact with the anilox roller 1, presses the air out of the empty cups (not shown) of the anilox roller 1, these cups being largely filled with ink and then enter the color supply of chamber 6.
  • the inventive design of the order unit also has the particular advantage that the latter can be adapted to existing flexographic printing units. In particular, it can be subsequently integrated into a flexographic printing unit and easily removed.
