Definitions

  • the invention relates to a casting head for curtain casting according to the preamble of claim 1.
  • the curtain casting is a widely used method for coating objects of all kinds today. in the photo industry in the production of photographic materials, for the painting of wood and metal plates and recently also for the coating of electrical circuit boards with e.g. Solder resist or the like used.
  • a slot caster is usually used, this is a casting head with an adjustable casting gap at its lower end, through which the coating compound emerges in doses and then sinks down from there onto the material to be coated in a free-falling curtain.
  • a known casting head of this type consists of two jaws or shells articulated at their upper ends, at the lower ends of which a knife-like bar is provided, which bars form the casting gap between them, the width or width of the casting gap being brought closer to one another or removed from one another two casting bowls is regulated. To clean the pouring head, one of the two bowls can be folded up and the pouring head opened.
  • This well-known pouring head has several serious disadvantages. So u m ss eg Giessspaltweite after jedem.Oeffnen of the runner to be reset, which is critical and tedious and the result depends on the diligence of the operators. Furthermore, the gap width setting can only be locked in the direction of closing, there is no clear locking against unintentional opening of the casting gap. Furthermore, the strips forming the casting gap (pouring lips) can only be replaced laboriously in the event of damage and then require a lengthy and time-consuming readjustment each time. Furthermore, the length of the casting gap cannot be changed easily. In addition, the known casting head has the disadvantage of moving sealing surfaces on the end faces. There are only ground sealing surfaces that often leak. Seeping varnish hardens and, if the pouring head is then difficult to open, easily damages the sanded surfaces. Finally, the well-known casting head consists of a heavy chrome steel welded construction and is therefore relatively expensive to manufacture.
  • the invention is now intended to improve a casting head of the type in question, while avoiding the shortcomings of the known casting heads, so that no adjustment of the casting gap after opening the head is necessary, that the casting gap can be easily changed, and that sealing problems are largely reduced .
  • the casting head according to the invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing.
  • the only drawing figure shows a vertical section through the pouring head.
  • the casting head shown is mounted in a frame G. It comprises a base plate 1, two casting head shells 2 and 3 and a casting ruler 4 with a casting gap 41.
  • the two shells 2 and 3 are provided on their mutually facing sides with recesses which together form two elongated distribution channels 21 and 22 which are connected to one another.
  • the two shells 2 and 3 are hinged to the base plate 1 by means of hinges 23 and 33 about axes 24 and 34 which are parallel to the longitudinal extension of the casting ruler 4, so that they therefore move from the vertical position shown, in which the casting head is closed, to a horizontal position can be unfolded. In this position, the casting head is open and the casting ruler 4, which is loosely arranged in a corresponding recess 12 in the base plate 1, can be removed from the casting head or replaced.
  • a sealing cord 35 is provided, which is inserted into a circumferential groove 36 in the sealing surface 37 of the shell 3.
  • the sealing against the casting ruler 4 takes place by means of a further sealing cord 45 in a circumferential groove 46 in the surface of the casting ruler 4.
  • the coating material is supplied via a line connection 5, which opens into the upper distribution channel 21 via an opening 31 in the right casting head shell 3.
  • the two casting head shells 2 and 3 are held together by clamps 6.
  • the casting ruler can be exchanged quickly and effortlessly if it is defective or soiled, any adjustment being omitted, since the casting gap in the ruler is precisely predetermined.
  • the dimensions of the casting gap can be easily changed at any time by inserting a corresponding casting ruler. Since the sealing of the individual parts of the casting head does not take place on moving sealing surfaces, there are no sealing problems.
  • the design of the pouring head is simple and inexpensive.
