Definitions

  • the invention relates to a mixing device for two-component adhesive that can be integrated into a dispenser device provided with an outlet opening of a dispenser tube, for adaptation to a cartridge with a central first opening surrounded by a first hollow-cylindrical wall for dispensing an adhesive component B of Two-component adhesive and a second hollow-cylindrical wall concentrically surrounding the first hollow-cylindrical wall and forming a second opening for dispensing an adhesive component A of the two-component adhesive.
  • Mixing devices of the type mentioned at the outset are used in the prior art in order to dispense components A and B of a two-component adhesive directly within a dispensing device immediately before use mix and thus make a manual apriori mixing process unnecessary.
  • the known mixing devices all have the disadvantage that the effectiveness of mixing the components is not yet sufficient enough to actually produce a homogeneous mixture.
  • the object of the invention is therefore to create a mixing device whose effectiveness in mixing the components involved is improved compared to the known mixing devices.
  • the mixing device contains a base panel and two concentrically arranged ring elements connected to the base panel and protruding from the base panel, an inner ring element for receiving adhesive component B from the first opening of the cartridge is formed and an outer ring element for receiving adhesive component A is formed from the second opening of the cartridge, and wherein the inner ring element has passage openings to introduce adhesive component A into the space between the inner and outer ring element, and the outer ring element passage openings in order to introduce a mixture of adhesive component B and adhesive component A, which is present in the space between the inner and outer ring element, into the dispensing device.
  • Preferred embodiments of the invention are the subject matter of the subclaims, the elements of which act in the sense of a further improvement of the approach to the solution of the object on which the invention is based.
  • the mixing device contains a base panel and two concentrically arranged ring elements connected to the base panel and protruding from the base panel, an inner ring element for receiving adhesive component B from the first opening of the cartridge is formed and an outer ring element for receiving adhesive component A is formed from the second opening of the cartridge, and wherein the inner ring element has passage openings to introduce adhesive component A into the space between the inner and outer ring element, and the outer ring element has passage openings to a Bringing the mixture of adhesive component B and adhesive component A present in the space between the inner and outer ring element into the dispenser means that both component B and component A move in a radial direction within the mixing device and dab ei are forced perpendicular to a conveying direction within the dispensing device, a component B necessarily being brought into the conveying direction of a component A and thus necessarily mixing with component A.
  • the base panel of the mixing device is provided with one or more peripherally arranged recesses through which a mixture of adhesive component B and adhesive component A after passing through the passage openings of the outer ring element can be funded in the donor facility.
  • the base panel is further designed to ensure that the mixing device is positioned within the dispensing device in which the center of the inner ring element comes to lie on a central axis of the dispensing device.
  • Both the mixing device and the dispensing device are preferably designed to be rotationally symmetrical, the passage openings of the inner ring element being arranged to convey the adhesive component B in the radial direction into the space between the inner and outer ring elements.
  • the passage openings of the outer ring element are arranged according to the invention in order to convey the mixture of adhesive component B and adhesive component A in the radial direction through the recesses of the base panel into the dispenser device.
  • the inner ring element is at least partially designed as a wall projecting at right angles from the base panel, with elastic lamellae for receiving the first hollow preferably in the area of the base panel's end face of this wall designed as a carrier element at a predetermined distance from one another -cylindrical wall of the dispenser device are arranged and provided between the lamellae gaps form a passage for an adhesive component B in the space between the inner and outer ring element of the mixing device.
  • the ends of the lamellae remote from the base panel are preferably beveled sloping towards the outside for a guided reception of the first hollow-cylindrical wall of the dispenser device.
  • the outer ring element is arranged at an acute angle with respect to the at least partially hollow-cylindrical inner ring element protruding at right angles from the base panel.
  • the outer ring element is connected to the base panel in particular within the peripherally arranged recesses of the base panel.
  • the base panel and the inner ring element and the outer ring element are preferably formed in one piece.
  • a Kelmix mixing element arranged within the dispenser tube of the dispenser device is preferably fastened in the area of the end face of the base panel remote from the ring elements.
  • the illustrated mixing device 100 according to the invention for two-component adhesive is intended for integration into a dispenser device 200 provided with an outlet opening 211 of a dispenser tube 210.
  • the mixing device 100 is for adaptation to a cartridge 300 with a central first opening 311 surrounded by a first hollow-cylindrical wall 310 for dispensing an adhesive component B of the two-component adhesive and one concentrically surrounding the first hollow-cylindrical wall 310 and one second opening 321 for dispensing an adhesive component A of the two-component adhesive forming second hollow-cylindrical wall 320.

  • the base panel 110 of the mixing device 100 is provided with one or more peripherally arranged recesses 111 through which a mixture of adhesive component B and adhesive component A can be conveyed into the dispensing device 200 after passing through the passage openings 131 of the outer ring element 130.
  • the base panel 110 is further designed to ensure a placement of the mixing device 100 within the dispenser device 200, in which the center point 122 of the inner ring element 120 comes to lie on a central axis of the dispenser device 200.
  • Both the mixing device 100 and the dispensing device 200 are designed to be rotationally symmetrical, the passage openings 121 of the inner ring element 120 being arranged around the adhesive component B in a radial direction To promote direction in the spatial area 140 between the inner and outer ring element 120, 130.
  • the passage openings 131 of the outer ring element 130 are arranged in order to convey the mixture of adhesive component B and adhesive component A in the radial direction through the recesses of the base panel 110 into the dispenser device.
