Definitions

  • the invention relates to a device for coating a material web, in particular a paper or cardboard web, with two press rolls mounted axially parallel next to one another in a frame, of which one press roll can be pressed against the other by means of an actuating element against the other press roll to form a press nip through which the material web is guided, and with an application and metering system for at least one press roll
  • Film presses are also used to coat paper or cardboard webs with pigment coating color, i.e. evenly apply a covering layer to the surface.
  • coating color it must be ensured that not too much color is printed into the web as it passes through the press nip endeavors to set the lowest possible line pressure between the two press rolls. It has been shown that a desired line pressure close to 0 N / m cannot be achieved, since the pressure is too low Pressure in the hydraulic or pneumatic control element causes the swiveled press roll to become unstable. The press nip between the two press rolls becomes unstable with negative effects on the quality of the coated web
  • the invention is therefore based on the object of improving a coating device of the generic type in such a way that a low line pressure can be set in the press nip between the two press rolls
  • the counterforce makes it possible to build up sufficient pressure in the pressing hydraulic or pneumatic actuating element for stable operation of the device and at the same time to set the line pressure in the press nip very low
  • Figure 1 shows a side view of an overall view of a film press
  • Figure 2 shows a schematic diagram of the arrangement and operation of the compression spring between the press rolls
  • Figure 3 shows a side view of a section of a device in which the counterforce is adjustable
  • the coating device shown in FIG. 1 is integrated in a paper machine.It consists of two press rolls 2, 3 which are rotatably mounted axially parallel to one another in a frame 1, one of which press roll 2 is stationary, the other press roll 3 is circumferentially pressable against the first press roll 2 Press roller 3 is suspended between two lateral pivot levers 4, which are mounted in the frame 1 by means of a hydraulic piston-cylinder unit as an actuating element 5 about a pivot axis 6 in the direction of the press roller 2 and can be pivoted away therefrom 3 print circumferentially against the press roller 2 Alternatively, a pneumatic piston-cylinder unit can also be used as the actuating element 5. A pneumatic bellows without piston can also be used as the actuating element 5, as shown in FIG. 2, when the press roller 3 swivels against the press roller 2 there is a press nip 7 to which the Coated paper web 8 is fed from above by a guide roller 9.
  • the two press rollers 2, 3 are preferably rubberized on their outer surface
  • coating material 7 is fed to the press nip 7 on the inlet side of the web 8 for both web sides.
  • an application and metering system 10, 11 is arranged on the press nip 7 on each press roll 2, 3 each application and metering system 10, 11 preferably has an application chamber which is open towards the respective press roller 2, 3 and into which coating material is fed under pressure.
  • each application chamber is closed off by a metering element, which on the press roll 2, 3 applied coating material is stripped down to the desired film thickness.
  • the metering element used is preferably a doctor rod with a structured surface, that is to say elevations and recesses, with which volumetric metering can be used.
  • Doctor rods with circumferential rollers are preferably used
  • the coating material applied in metered fashion on the lateral surfaces of the press rolls 2, 3 is transferred to the web 8 in the press nip 7.
  • the web 8 coated on both sides is fed from a non-contact guide element 12 to a dryer, not shown.
  • the line pressure between the two press rolls 2, 3 is set via the hydraulic or pneumatic pressure in the actuating element 5, which can be varied via a proportional valve.
  • a minimum pressure in the control element 5 is required. This minimum pressure is too great as a line pressure between the two press rollers 2, 3 for certain surface coatings with pigment coating ink, since too much ink would be pressed into the paper or cardboard web 8.
  • At least one compression spring 13, 14 is arranged between the two press rolls 2, 3, which generates a counterforce pushing the press rolls 2, 3 apart in the press nip 7.
  • Two springs 13, 14 are preferably arranged on each longitudinal side of the device between the bearing housings 15, 16 of the press rolls 2, 3, which are held at an adjustable distance by a spacer bolt 17.
  • the spacer bolt 17 transmits the pressing force of the actuating element 5 against the force of the springs 13, 14 to the bearing housing 15, 16 and thus to the press rollers 2, 3.
  • the springs 13, 14 are designed so that they have a largely constant spring constant, so that the counterforce increases linearly with the distance between the two press rolls 2, 3 from each other.
  • the springs 13, 14 are designed as leaf springs which are supported on the respective bearing housing 15, 16. You have a spring travel, which is sufficient in connection with the spring constant to build up such a large back pressure that the line pressure between the press rolls 2, 3 can be set to zero at the required minimum pressure of the actuating element 5.
  • the length of the spacer bolt 17 can preferably be changed so that the basic position can be set in which the counterforce of the springs 13, 14 is effective.
  • the spacer pin 17 has an articulated ball on one side, which is mounted in an articulated socket 18 fastened to the spring 14 on the outside.
  • a sleeve 19 screwed, the axial position of which can be adjusted relative to the bolt 17.
  • the spherical shell-shaped end of the sleeve 19 is also mounted in a joint socket which is fastened to the outside of the second spring 13.
  • this construction enables a pivoting movement of the bolt 17 relative to the bearing housings 15, 16, so that the pivoting movement of the press roll 3 against the press roll 2 is not impaired. So that the spacer bolt 17 does not bend when the press roll 3 is pivoted away, it is held in its position in the socket 18 by a clamping ring 20. By removing the clamping ring 20, the spacer 17 with the screwed-on sleeve 19 can be completely removed if the device is to be operated without the action of the springs 13, 14.
  • the effective length of the spacer bolt 17 is set as a basic setting so that the press roll 2, 3 are at a distance of 0 millimeters from one another at the minimum pressure required for the actuating element 5.
  • the line pressure required for optimal coating between the press rolls 2, 3 is then set by increasing the pressure in the actuating element 5.
  • the pressure of the actuating element 5 is varied such that the two press rolls 2, 3 are at the same distance from one another on each longitudinal side, and so the line force is uniform over the entire axial length of both press rolls 2, 3.

Abstract

Les dispositifs connus utilisés pour recouvrir des bandes de papier ou de carton (8) comprennent deux rouleaux de pression (2, 3) montés l'un à côté de l'autre, leurs axes étant parallèles, dans un châssis (4), un rouleau de pression (3) pouvant être pressé au niveau de sa périphérie contre l'autre rouleau de pression (2) au moyen d'un élément de commande (5), pour former une fente de pression (7), à travers laquelle est guidée la bande (8). Au moins un rouleau de pression (2, 3) contient un système d'application et de dosage (10, 11) qui applique un film dosé de matériau de recouvrement sur l'enveloppe du rouleau de pression (2, 3) qui, ensuite, est transféré à la bande (8) se trouvant dans la fente de pression (7). Selon l'invention, un ressort de pression (13, 14) est monté entre les deux rouleaux de pression (2, 3) et produit, dans la fente de pression (7), une force antagoniste de pression séparant les rouleaux de pression (2, 3).
