Definitions

  • the invention relates to a device for thin-layer application of a liquid coating agent to a belt, consisting of an application roller rolling on the surface of the belt and a conveyor belt arranged between a storage container for the coating agent and the application roller and resting against the application roller, which endlessly turns to the application roller parallel pulleys is guided.
  • strips are to be provided with a thin layer of a coating agent that is liquid at least during application, high demands are often placed on the uniformity of the applied layer, as is the case, for example, with oiling, plastic coating or strip galvanizing of sheet metal strips.
  • the use of a conveyor belt instead of the usual oil conveyor rollers has the advantage that the conveyor belt in both upper as well as in the lower area of the roller jacket can be brought up to the application roller without endangering the sufficient immersion of the conveyor belt in the coating agent bath, so that the belt can be coated from above and from below.
  • all centrifugal effects caused by spraying can be avoided. Because the coating agent film on the conveyor belt remains constant even at different speeds, a coating agent layer of uniform thickness can thus be transferred to the application roller, which is a prerequisite for uniform coating of the belt.
  • a disadvantage of this known device is that the application width of the coating agent is fixed by the conveyor belt width.
  • the conveyor belt is chosen for a wide range, the disadvantages arising from the conveyance of an excess amount of coating agent due to the greater conveyor belt width having to be accepted for belts to be coated.
  • the invention is therefore based on the object to avoid this deficiency and to improve a device of the type described in such a way that the application width of the coating composition can be adapted to the particular width of the strip to be coated using simple constructional means.
  • the invention solves this problem in that in the reservoir at least two immersed in the coating agent bath above the level of the bath Conveyor belt adjacent application bodies are provided, they only extend over a part of the conveyor belt width, are offset with respect to one another in the conveying direction of the conveyor belt and are displaceably mounted parallel to the deflection rollers.
  • the overlap area does not interfere with the uniformity of the belt coating because, on the one hand, the application body following in the conveying direction of the conveyor belt also serves as a wiper for the excess amount of coating agent applied by the previous application body and, on the other hand, the conveyor belt during the transfer of coating agent to the application roller rolling on the belt surface to even out the Coating agent layer ensures the width of the application, so that any irregularities that may occur are compensated for before the coating agent is applied to the tape to be coated.
  • application widths for the coating agent can be set between half the conveyor belt width and the entire conveyor belt width. If an even larger area is to be specified for the setting of the application width of the coating agent, three or more application bodies with a correspondingly smaller application width are required. Particularly simple constructional relationships result if three application bodies are provided in the storage container, of which the application body, which is centered with respect to the conveyor belt width, is immovably mounted in the direction of the conveyor belt width. With the same dimensions of these application bodies each having an application width of one third of the conveyor belt width, belts with a width between one third of the conveyor belt width and the conveyor belt width can advantageously be coated.
  • the application bodies can be pressed resiliently onto the conveyor belt. This measure advantageously supports the wiping effect of the excess coating agent in the overlap area of the application body.
  • absorbent application bodies that do not perform a conveying movement can certainly be used within the scope of the invention if a sufficient flow of coating agent to the conveyor belt is achieved via the suction force, particularly favorable conditions result from application bodies that are themselves subjected to a conveying movement, so that the coating agent is removed the supply container in the desired amount can be fed to the conveyor belt.
  • application bodies which consist of rotatably mounted application rollers, advantageous conditions can be created for conveying coating agents. These application rolls can be connected to a separate drive. Synchronous drive conditions can, however, be achieved simply by pressing the application rollers against the conveyor belt and rotating them from the conveyor belt.
  • the strip 1 to be coated is passed through between a support roller 3 mounted on a frame 2 and an application roller 4 for the coating agent, for example oil pulled, the coating agent located on the applicator roller 4 is transferred to the belt 1.
  • a conveyor belt 5 is used to apply the coating agent to the application roller 4, said conveyor belt being endlessly guided around deflection rollers 6 parallel to the application roller 4, which are held together with the application roller 4 in a rocker arm 7 which is pivotably mounted in the frame 2.
  • a working cylinder 8 articulated on the rocker 7 is provided to position the application roller 4 on the belt 1 to be coated.
  • three application bodies 10, 11 and 12 are provided in the storage container 9, which run parallel to the deflecting rollers 6 of the conveyor belt 5 and each extend over a third of the conveyor belt width .
  • These application bodies 10, 11 and 12 are designed as application rollers and are offset from one another in the conveying direction of the conveyor belt 5, the extent of which exceeds the diameter of the application bodies 10, 11 and 12 of the same diameter.
  • the application bodies 10 and 11 can therefore be moved parallel to the deflecting rollers 6 with respect to the application body 12, which is centered with respect to the conveyor belt width, as a result of which the entire application width of the coating agent changes. This is because the coating agent is transferred from the application bodies immersed in the inspection agent bath 13 to the conveyor belt 5 resting on the application bodies 10, 11 and 12 above the bath level 14.
  • these hollow application bodies 10 and 11 are on coaxial guide rods 15 slidably mounted and are connected to an actuator. 2, consists of an actuating spindle 17 which can be actuated via a hand crank 16 and which has two opposing threaded sections, so that the adjusting nuts 19, which are non-rotatably supported on a guide rail 18 and cooperate with one threaded section each, are moved in opposite directions along the adjusting spindle 17.
  • These adjusting nuts 19 engage the application bodies 10 and 11 via driver forks 20, so that these application bodies 10 and 11 are also displaced in opposite directions on the guide rods 15.
  • the application width of the coating material can be varied between one third of the conveyor belt width and the full conveyor belt width if the application bodies 10, 11 and 12 each correspond to one third of the conveyor belt width.
  • the application bodies are pressed resiliently onto the conveyor belt 5.
  • the guide rods 15 for the application bodies 10 and 11 according to FIG. 4 are guided in a height-limited manner in lateral bearing housings 21, in which pressure springs 22 acting on the ends of the guide rods are inserted, by means of which the application bodies are pressed against the conveyor belt 5.
  • these applicators are rotatably mounted on sliding sleeves 23, which are non-rotatable but axially displaceable on the guide rods 15 via a tongue and groove connection 24.
  • a similar construction is provided for the resilient mounting of the middle application body 12, which cannot be moved in the direction of the conveyor belt width, as shown in FIG. 3.
  • the application body 12 is namely rotatably mounted on a support shaft 25, which in turn is acted upon by compression springs 22 inserted in the bearing housing 21.
  • set screws 26 can be provided, with the aid of which the prestressing of the compression springs 22 can be changed in the desired sense.
