Definitions

  • the invention relates to a mouthpiece for dispensing devices which serve the dispensing of two-component masses, with a mixing tube which is provided for connection to a dispensing nozzle on the device with two outlet openings for the individual components.
  • An extrusion device for two-component compositions is known, for example, from CH-PS 670 580.
  • such a device usually has a dispensing nozzle which is provided with an outlet opening for one component each.
  • the individual components are separated from each other inside the device and enter a mouthpiece through the respective outlet openings, which is connected to the device-side dispensing nozzle.
  • the two components are mixed within the mouthpiece, which is decisive for the final hardening.
  • the individual components are pressed out by applying a certain pressure generated in the device.
  • a print can be applied manually or with additionally supplied print media. If such pressure is applied without -
  • a mouthpiece with hardened components is removed prematurely, there is a risk that one of the components will strike back through the outlet opening of the other component into the extrusion device.
  • the components can be mixed within the extrusion device, so that curing takes place, for example, in the area of the extrusion mechanisms, which can lead to malfunctions in the extrusion device.
  • Such a fault is only possible by time-consuming dismantling and cleaning of the dispenser.
  • the components are kicked back arbitrarily, mostly depending on the viscosity differences and any pressure differences between the individual components.
  • the invention has for its object to provide a mouthpiece for a squeezing device of the type described above, with which it is avoided that malfunctions caused by a kickback of component parts in the squeezing device occur.
  • the object is achieved in that at least one one-way valve cooperating with one of the outlet openings and allowing the passage of the respective component is provided in the mixing tube.
  • the mouthpiece according to the invention with at least one one-way valve, which cooperates with one of the outlet openings, has the consequence that at least one of the two components must first pass through the one-way valve and then mixed with the other component in the mixing tube.
  • the one-way valve only opens as long as the component flows through.
  • the one-way valve closes, so that no further portion of the component can escape and, moreover, no portion of the other component comes from the mixing tube to the outlet opening assigned to the one-way valve. If the squeezing process is interrupted for a certain time, so that the mixed components harden in the mouthpiece, this results in that at the point where the individual components flow together for the first time, i.e.
  • the curing takes place first.
  • a portion of cured components can thus form, in particular around the open one-way valve, which then has the consequence that the mixing tube is closed to the device by the portion of the cured components.
  • This mouthpiece according to the invention is also a disposable part, which has to be removed from the pressing device after the pressing process has been interrupted. For the satisfactory functioning of the further squeezing process, it is necessary as before to provide the dispensing nozzle of the squeezing device with a new mouthpiece.
  • a one-way valve is expediently arranged at a distance from the connection point to a first outlet opening on a pipe section which is mounted coaxially in the mixing tube and can be connected to the corresponding outlet opening. It is thereby achieved that the two outlet openings on the device side are separated from one another, which is particularly advantageous if only one of the outlet openings interacts with a one-way valve. Only after the component passing through the pipe section has also passed through the one-way valve is it mixed with the other component located in the mixing pipe.
  • the pipe section is preferably arranged coaxially within the mixing pipe. This is the pipe section for the passage of one component and the annular space between the tube piece and the mixing tube are provided for the passage of the other component.
  • the annular space between the tube piece and the mouthpiece can at most be penetrated by ribs, which on the one hand serve to stabilize the tube piece, but on the other hand allow enough space for the passage of the one component between the tube piece and the mixing tube.
  • one or more openings on the pipe section that can be covered by an elastically deformable part are suitable as one-way valves.
  • These openings are advantageously radial passages which are arranged in the mouth region of the pipe section.
  • An elastically deformable part for these, for example, radially arranged passages is expediently an elastic sheath which surrounds the openings.
  • This elastic sleeve preferably has the shape of a tube.
  • the elastic sleeve is connected at its end area facing the mouth of the mixing tube to the mouth area of the pipe section and can be elastically deformed at its opposite end area by the pressure of the component flowing through the pipe section.
  • a quasi deflection baffle is thus formed for the component flowing through the pipe section, which on the one hand has an advantageous effect on the mixing process and on the other hand also has an advantageous effect on the closure to be formed by a proportion of hardened components.
  • a further one-way valve is expediently arranged in the area of the connection point to a second outlet opening.
  • this further one-way valve is arranged in the area of the connection point, there is still a spatial separation of the outlet points, ie in the present case the one-way valves.
  • the further one-way valve preferably has a bellows that is axially compressible by the pressure of the component flowing through the second outlet opening.
  • a bellows acts in the sense of an elastically deformable part analogous to the description in connection with the first one-way valve, only with the difference that the elastic bellows are axially deformable and the elastic sleeve is radially deformable. Due to the internal stress, the bellows covers the second outlet opening until compression occurs due to the pressure of the component flowing out through the outlet opening.
  • the mixing tube is advantageously made so long that the one-way valve or valves are sufficiently protruded from the mixing tube. This creates a sufficiently long mixing section, which guarantees sufficient mixing of the individual components.
  • the mouthpiece according to the invention is advantageously used in connection with an extrusion device which has a first outlet opening opening into the mixing tube and, upstream of this first outlet opening, coaxially in front of this first outlet opening and a second outlet opening opening into the tube section.
  • a device of this type can, for example, be designed in such a way that the outlet opening opening into the mixing tube is used for the delivery of prepolymer or similar resins and the outlet opening opening coaxially therewith is provided for the delivery of an activator.
  • the mouthpiece consists essentially of a mixing tube 1 and a tube piece 2.
  • the mouthpiece is connected to an extrusion device, the front part 3 of which is indicated by dash-dotted lines.
  • the front part 3 is indicated by a first outlet opening 3a (shown in the closed position) and a second outlet opening 3b upstream of this first outlet opening 3a coaxially in the squeezing direction.
  • the first outlet opening 3a opens into the squeezing tube 1 and the second outlet opening 3b opens into the pipe section 2.
  • the pipe section 2 is held and stabilized via ribs 4 in the mixing pipe 1. It is also shown how the pipe section 2 is provided with a bore 2a which tapers slightly in the pressing-out direction and which opens into radial passages 2b at its end pointing in the pressing-out direction. These passages 2b located in the mouth region of the pipe section 2 are surrounded by an elastic sheath 5. This elastic sleeve 5 is connected to the pipe section 2 at its end area facing the mouth of the mixing pipe 1, ie this end area is surrounded, for example, by projections 2c of the pipe section 2. The casing 5 can be clamped into the space formed by the projections 2c and, if necessary, additionally glued.
  • the envelope 5 is at its opposite end region radially expandable from the pressure of the component flowing through the pipe section 2, so that in this area the component emerging through the passages 2b can reach the mixing tube 1 after expansion of the casing 5 and mix there with the other component.
  • the end of the mixing tube 1 facing the dispenser can also be provided with one or more recesses distributed over the rear end face, for example in the form of notches 1a, so that 1 edges form on the rear end face of the mixing tube. These edges can be used to clean the respective area of the squeezing device by rotating the mixing tube 1 about its own axis so that residues of the individual components can be removed.
  • FIG. 2 shows a further mouthpiece with a mixing tube 6.
  • the mouthpiece with its mixing tube 6 is connected to an extrusion device, the front part 7 of which is indicated by a dot-dash line.
  • the front part 7 is indicated with a first outlet opening 7a and a second outlet opening 7b (shown in the open position), the first outlet opening 7a being arranged coaxially in the squeezing direction to the outlet opening 7b.
  • the first outlet opening 7a opens into a pipe section 8.
  • This pipe section 8 is provided with a bore 8a which tapers slightly in the direction of squeezing and which opens into radial passages 8b at its end pointing in the direction of squeezing.
  • These passages 8b located in the mouth region of the pipe section 8 are surrounded by an elastic sleeve 9.
  • the elastic sleeve can be radially deformed by the pressure of the component flowing through the bore 8a.
  • the pipe section 8 is held and stabilized by means of ribs 8c which are supported on the mixing pipe 6.
  • the pipe section 8 In the area pointing counter to the pressing direction, the pipe section 8 is surrounded by a bellows 10. This bellows 10 axially covers the outlet opening 7b. The bellows 10 is axially compressed by the pressure of the component flowing through the outlet opening 7b, so that the component can emerge and flow in the pressing direction along the annular space between bellows 10, pipe section 8 and mixing tube 6. In the area of the passages 8b, the individual components flowing out of the passage openings 7a, 7b mix.
  • Plastic is a suitable material for the mixing pipe 1, 6 and the pipe section 2, 8.
  • the sheath 5, 9 and the bellows 10 are also advantageously formed from plastic, but from a highly elastic one.
