Definitions

  • the invention relates to a device for guiding a rod-shaped, heat-softenable adhesive material when inserted into the guide channel of a hot glue device, in the form of an elastically flexible sleeve, which is attached with one end to a heatable body containing the guide channel.
  • a device of this type is e.g. in the case of so-called hot glue guns, which are used to insert an adhesive material rod, e.g. to soften by electrical heating and to let it emerge in liquid form at an outlet opening.
  • the stick of adhesive material is pushed into the elastically flexible sleeve by means of a mechanical device or by finger pressure and passes through this sleeve into the heatable body, in which it is liquefied by heating.
  • the sleeve used to insert the adhesive material rod is elastically flexible because, on the one hand, the thickness of the adhesive material rods is subject to certain tolerances, and on the other hand, it should be possible to insert the adhesive material rods comfortably without great care in the alignment.
  • An elastically flexible sleeve securely picks up the stick of adhesive material even with slight canting and then guides it into the heatable body in a precise alignment.
  • the heat transfer described results in heating of the sleeve material in particular, which means that the flowing back liquid adhesive material does not cool down so quickly that it could cause an unusually large increase in the diameter of the adhesive material rod located in the sleeve.
  • the frictional resistance on the inner wall of the sleeve is kept low, regardless of larger fluctuations in the diameter of the adhesive material rod, because on the one hand an increase in the diameter of the adhesive material rod is prevented, and on the other hand the sleeve material is kept at an elevated temperature so that it thicker adhesive material rod can yield more easily and for this reason alone there is always a relatively low surface friction on the inner wall of the sleeve.
  • the sleeve has a lip-shaped peripheral edge in its interior which seals against an inserted rod-shaped adhesive material. It is hereby achieved that a lip seal is formed with the adhesive material rod inserted into the sleeve, which can even penetrate into the already softened adhesive material rod if it is sufficiently close to the heatable body and thereby prevents liquefied adhesive material from flowing back. Should liquefied adhesive material still flow back, for example, when an adhesive material rod is inserted quickly, its premature solidification in the sleeve is prevented or at least delayed in the manner described above.
  • the device can advantageously be designed in such a way that the metal jacket surrounds the sleeve at a distance on its section free of the heatable body. This ensures that in the case of a backflow of adhesive material, which is then e.g. is solidified by not using the hot-melt adhesive device, although an enlargement of the diameter of the sleeve which accommodates this adhesive material was possible, this enlargement was limited when the stated distance between the sleeve and the metal jacket was filled by the sleeve material. This then touches the metal jacket, and upon subsequent heating of the hot glue device, an even better heat transfer to the sleeve material is achieved precisely where the adhesive material rod thickened by the adhesive material that has flowed back previously is arranged. This further development of the invention thus enables the device to work reliably even if, for example, the lip seal explained above is defective or does not exist.
  • the metal jacket advantageously has the shape of a wire spiral. On the one hand, this enables a comfortable one. Assembly of the sleeve on the heatable body, the wire spiral reliably holding the sleeve on it due to its resilient property, on the other hand, a wire spiral does not hinder the elasticity of the sleeve, which is desired for the most convenient insertion of an adhesive material rod.
  • the distance between the sleeve and the metal jacket is expediently formed by reducing the outside diameter of the sleeve. This reduces the manufacturing costs for the metal jacket, regardless of its design as a tubular element or as a wire spiral.
  • a further embodiment of the invention is characterized in that the wire spiral forming the metal jacket has a resistance in the area of the reduction in the outer diameter, but in the rest of the turns are closely adjacent. This ensures that the heat transfer between the section seated on the heatable body and the free section of the sleeve becomes so great that the adhesive material rod is heated and liquefied too early.
  • the spacing of the turns in the area of the reduction in the outer diameter the amount of heat can be determined which passes to the section of the sleeve which is free of the heatable body.
  • the sleeve expediently has a conical widening of its inner diameter in the direction of insertion, which further reduces the friction of an inserted stick of adhesive material on the sleeve inner wall.
  • a conical widening is particularly advantageous if a lip-shaped peripheral edge of the type described is provided in the sleeve anyway.
  • the hot glue device has e.g. a pistol-shaped housing, of which a housing half-shell 10 can be seen in the figure.
  • This half-shell can, for example, be made of plastic using injection molding technology and has a handle part 11 that runs downwards and a shaft 12 that runs from right to left .
  • This serves to heat a heatable body 14, which e.g. consist of aluminum and can be manufactured using injection molding technology.
  • the heatable body 14 has a conically narrowing guide channel 15 from right to left, in which an inserted stick of adhesive material 16 is liquefied and then exits again in a liquefied form via suitable devices, which are not shown in the figure.
  • the adhesive material rod 16 is partially shown in the figure and is pushed in the direction of the arrow A into an elastically flexible sleeve 17, the left end 18 of which is plugged onto the heatable body 14 and is inserted as a unit into the housing half-shell 10.
  • the left end 18 of the elastically flexible sleeve 17 is held on the heatable body 14 by a metal wire spiral 19, the section 20 of which seals the sleeve end 18 in a sealing manner on the heatable body 14 as a result of its spring force acting in the wrap direction and whose section 21 a section of the heatable body free length of the sleeve 17 surrounds with a small distance 22.
  • the unit consisting of the heatable body 14, the sleeve 17 and the metal wire spiral 19 is inserted into the housing half-shell 10 between webs 23 and 24 molded onto it and is held by the latter in the housing half-shell 10.
  • Appropriate webs can be provided on a further ekoruseschreibschale G which is applied to the arrangement shown in the figure and then fixedly connected to the housing half-shell 10th
  • the sleeve 17 has a guide channel 25 which widens conically in the direction of insertion and ends at a lip-shaped peripheral edge 26 which sits directly in front of the end of the heatable body 14. If an adhesive material rod 16 is inserted into the guide channel 25 in the direction of the arrow A shown, then there is first a frictional contact only at the inlet opening 26 of the sleeve 17.
  • the metal wire spiral 19 due to the good thermal conductivity inherent in the metals, in addition to mechanically holding the sleeve 17 on the heatable body 14, also causes heating in the region in which it surrounds the sleeve in front of the heatable body 14. If, despite the seal caused by the adhesive material rod 16 between the latter and the lip-shaped peripheral edge 26, liquefied adhesive material flows out of the guide channel 15 of the heatable body 14 back into the guide channel 25 of the sleeve 17, this adhesive material cannot cool prematurely, since the metal wire spiral 19 also the portion of the sleeve 17 free from the heatable body 14 is heated to a certain extent.
  • the sleeve 17 can expand slightly when adhesive material has flowed back into the guide channel 25. If this adhesive material then solidifies as a result of the adhesive device not being used, the sleeve 17 will then touch the metal wire spiral 19 due to its expansion.
  • the lip-shaped peripheral edge 26 effects a seal between the two guide channels 15 and 25 when an adhesive material rod 16 is inserted into it. This sealing is carried out for a certain diameter range of adhesive material rods. Should the lip seal created with the lip-shaped peripheral edge 26 e.g. by aging or by too thin adhesive material rods, the operational impairment due to flowing back and already softened adhesive material, which was unavoidable in previous devices of this type, is avoided by the heat effect of section 21 of the metal wire spiral 19.
