Definitions

  • the present invention relates to the application of hot-melt adhesives by heads to which the adhesive to be applied is supplied from melting devices where, by heating, the glue is provided with the fluidity necessary for the application, proposing a compact head having a joint fuser member and the applicator member of the molten glue.
  • melters are used to transform the glue from a solid state, in which they are traditionally supplied, to a fluid state necessary for application.
  • melters for converting hot melt glues into the fluid application state form large reservoirs located at a distance from the head through which the application of glue is performed.
  • the molten glue is transported through heated and insulated sheaths, so that the molten glue reaches the application head under the necessary fluidity conditions.
  • the invention relates to a compact head, which jointly integrates the glue fusion device and the applicator element, so that the passage of the molten glue between the two elements is direct, without conduction by heated ducts. not necessary.
  • This head which is the subject of the invention, comprises a heated reservoir for melting the adhesive and an application head, comprising a pulse pump for pass the melted glue from the melting tank to the application head.
  • the melting tank can be of variable shape, open or hermetically closed, the hot melt glue being introduced into the solid state, so that inside, thanks to the heat provided by the electrical resistances arranged around it of said reservoir, the glue melts while taking a fluid state, to be impelled up to the application head.
  • the melting tank is surrounded by an insulating layer, to prevent heat loss to the outside, in order to obtain the maximum exploitation of the energy consumption used for the glue fusion.
  • said compact head subject of the invention offers characteristics that are certainly advantageous compared to traditional heads with separate elements used for the application of hot melt adhesives.
  • the object of the invention relates to a compact head for the application of hot melt adhesives, comprising both the element for the melting of the glue and the element for applying the melted glue.
  • the compact head recommended is composed of a melting tank (1), which as illustrated on the figure 1 may have a cylindrical shape, which may also have other shapes, such as a prismatic shape, as illustrated in FIG. figure 4 , without altering the concept of the application head of hot melt glues or its function.
  • a melting tank (1) which as illustrated on the figure 1 may have a cylindrical shape, which may also have other shapes, such as a prismatic shape, as illustrated in FIG. figure 4 , without altering the concept of the application head of hot melt glues or its function.
  • said melting tank (1) must be hermetically closed, whereas for other types of glue which do not have this feature, a hermetic closure is not necessary.
  • Said melting tank (1) is connected directly to a glue application head (2), which may be of the lip type or any other conventional form of existing glue application nozzles, the assembly being provided with a pump (3) for pulsing molten glue from the melting tank (1) to the application head (2).
  • the melting tank (1) is surrounded by electrical resistances (not shown), in a peripheral chamber (4) filled with insulating material, and in the base said tank (1) comprises a series of outlets (5) of passage up to a chamber (6), which in turn communicates through a conduit (7) with the adhesive application head (2), electrical resistors (8) being incorporated in the spaces between the outlets (5) and around of the room (6).
  • the adhesive for the application is introduced in the solid state into the tank (1), falling by gravity onto the bottom provided with the outlets (5), so that thanks to the heat provided by the resistors surrounding the reservoir (1) an initial melting of the glue is produced, which ends to melt in the outlets (5) of the base, thanks to the heat of the resistors (7) which are in the spaces between the outlets (5) mentioned, the molten glue flowing to the chamber (6) where the melting state is maintained, and from said chamber (6) the molten glue is impelled by the pump (3) to the application head (2) , passage in which electrical resistors (8) are also included to maintain the glue in the state of fluidity suitable for the application.
  • the solid glue that is introduced into the reservoir (1) gradually melts in said reservoir (1), so that it reaches the lower outlets (5) in a semi-molten state, acquiring in said outlets ( 5) a fluidity that allows it to pass to the chamber (6), so that in this passage and in the chamber (6) the fusion is completed and maintained, the molten glue being driven directly from the melting zone up to the application head (2), so that there are no wide circulation passages in which the glue can cool and lose fluidity, the entire head therefore having a dimension allowing it to be used in small spaces.
