Definitions

  • the present invention relates to a dynamic mixer, in particular for dental materials with different viscosity.
  • the invention also relates to a method for producing a dynamic mixer, in particular for dental materials of different viscosity.
  • Impression materials usually consist of two pasty masses. These two components are filled into cartridges and squeezed out immediately before use and mixed in the process. So-called dynamic mixers are used for large-volume 10: 1 cartridges. These mixers have two inlet openings that are connected (attached) to the outlet openings of the double cartridge. The assembly is then placed in a mixer and the rotor of the dynamic mixer is connected to the drive shaft of the mixer. The mixing device influences the homogeneity of the mixed impression material via the ejection pressure and the speed and thus directly the product quality.
  • the two components In order for the mixer to work perfectly, it is essential that the two components are fed evenly until they meet at the rotor. If the mass flows of the two components fluctuate or if a mass flow breaks off partially or completely, the impression material becomes unusable. To avoid this, the two feed channels, from the inlet opening on the mixer to the rotor, must be perfectly balanced. In most cases, the outlet bores of the cartridges and the inlet openings of the mixer for the two components are designed with the same cross-sectional ratio as the later mixing ratio.
  • the 10: 1 cartridges and mixers currently in use at Kulzer have a surface area of approx. 12.2 mm 2 (catalyst) and 121 mm 2 (base). The ratio of the two cross-sections is thus 10: 1.
  • a dynamic mixer should be able to be used for a large number of different pasty masses, with a uniform supply of the two components being guaranteed for two of this large number of different masses until they meet at the rotor of the dynamic mixer.
  • the object of the present invention is achieved by a dynamic mixer, in particular for dental materials with different viscosities, the dynamic mixer comprising:
  • the chamber part comprising a mixing chamber
  • the closure part at least has two essentially parallel planes connected axially one behind the other on the side facing away from the rotor tip, wherein the plane facing away from the rotor comprises the first and the second inlet opening, wherein the plane facing the rotor has a first and a second passage opening to the mixing chamber, the first inlet opening and the first passage opening form a rectilinear channel, the at least two essentially parallel planes arranged axially one behind the other to form a supply channel between the second inlet opening and the second passage opening Forming connection to the mixing chamber, the feed channel running on an inner pitch circle of the closure part, characterized in that the dimensions of the feed channel are variable depending on the relative rotationally
  • the feed channel is a channel which preferably runs in an intermediate space between two planes, in particular between two planes arranged essentially in parallel.
  • the feed channel runs at the interface between the chamber part and the closure part and can be varied in length, width and height by rotating the chamber part and closure part relative to one another, so that the length of the path between the second inlet opening of the dynamic mixer and the second passage opening to the mixing chamber , Width and height can be varied.
  • the two substances can again reach the rotor at the same time by adjusting the length, width and height of the feed channel by rotating the chamber part and the closure part relative to one another. Every time you change the components, you have to change the dimensions of the feed channel, i.e. the path between the second inlet opening of the dynamic mixer and the second passage opening to the mixing chamber, by rotating the chamber part and the closing part relative to one another so that the two components arrive at the rotor at the same time .
  • the dynamic mixer can be used for several different pairs of components with different viscosities.
  • the two essentially parallel planes axially connected one behind the other can be two planar layers in the closure part, which are arranged adjacent.
  • Viscosity refers to the viscosity of liquids and gases (fluids). The greater the viscosity, the thicker (less flowable) the fluid is; the lower the viscosity, the more fluid (flowable) it is.
  • Dental materials preferably comprise dental impression materials comprising two components (2K), particularly preferably 2K polydimethylsiloxane (PDMS).
  • the partial circle formed by the feed channel encloses an angle of 20 to 170 degrees.
  • the length of the feed channel which is located on a pitch circle of the closure part, is thus variable and can be expressed in degrees of angle and in radians.
  • the cross section of the feed channel increases or decreases in the direction of the mixing chamber
  • the height and / or width of the feed channel increasing or decreasing in the direction of the mixing chamber
  • the height and / or width of the feed channel at the second passage opening to the Mixing chamber depend on the relative rotationally symmetrical position of the chamber part and the closure part.
  • the feed channel according to the invention has, for example, an additional flow resistance which can be increasingly pronounced due to a narrowing in the direction of the mixing chamber.
  • the height and / or width of the feed channel at the transition to the second inlet opening depend on the relative rotationally symmetrical position of the chamber part and the closure part.
  • the height and / or width of the feed channel at the transition to the second inlet opening can therefore be varied and depend on the relative rotationally symmetrical position of the chamber part and the closure part. Depending on the respective viscosity of the component, the height and / or width of the feed channel at the transition to the second inlet opening can be adjusted by simply turning the chamber part and the closure part relative to one another.
  • the renewal of the design of the dynamic mixer, in particular for dental materials relates to the feed channels, in particular for dental materials, between the insertion bores and the beginning of the mixing chamber or rotor.
  • a channel in the closure part on the way to the rotor transverse channel to the bore axis.
  • This channel is laid out helically and runs on the Pitch circle of the respective feed bores at an angle of 20 - 170 °.
  • the height and / or width of the channel increases, so that the channel cross-section increases and the flow resistance for the pastes flowing through changes and can thus be influenced.
  • the twisted placement of the closure part and the chamber part results in a different height of the channel at the transition to the insertion hole. This can be used to achieve the optimal balance between the two pasty masses.
  • the feed channel in particular for dental materials, has a spatially delimited partition wall on a further inner pitch circle or on an inner ellipsoidal path, the partition wall being part of the chamber part or part of the closure part, the partition wall separating the feed channel from the mixing chamber, depending on the relative rotationally symmetrical position of the chamber part and the closure part, the partition wall each assumes a different position relative to the feed channel.
  • the partition separates the mixing chamber and feed channel from one another.
  • the partition wall is either part of the chamber part or part of the closure part and forms a variable inner wall of the feed channel.
  • the position of the partition wall relative to the feed channel depends on the relative rotation of the chamber part and the closure part. With a high-viscosity component, the partition should form a shorter part of the inner wall of the feed channel than with a low-viscosity component.
  • the partition is another parameter for adapting a dynamic mixer to the viscosity of a component.
  • the chamber part or the closure part has at least one pin, the longitudinal axis of the at least one pin protruding into the feed channel.
  • the chamber part has at least one or two pins, the outer edge of which is on the same pitch circle diameter (+ play) of the feed channels of the closure part.
  • the pin protrudes into the feed channel and forms a flow barrier for the pasty mass when it is used later. Since the pin lies on the same pitch circle as the supply channels and the outer design of the two housings is rotationally symmetrical, the position of the two housing elements can be rotated relative to one another (angle ⁇ in FIG. 10). This changes the distance (radians) from the pin to the insertion hole.
  • the flow resistance in an application would decrease due to the barrier effect of the pin when pasty masses flow through the feed channel. This enables the mass flow of the paste to be balanced so that both pastes arrive at the rotor at the same time. The discard due to possible inhomogeneity during the initial mixing can thus be reduced.
  • the at least one pin of the chamber part whose outer edge is on the identical pitch circle diameter (+ clearance) of the feed channel of the closure part, protrudes into the feed channel.
  • the feed channel can have a variable cross section (without a pin). If the pin now protrudes into the feed channel, the result is the free cross section of the feed channel, which corresponds to the cross section of the feed channel minus the pin.
  • the free cross section in the feed channel can be adjusted.
  • the pin or pins are arranged on the chamber part and protrude into the feed channel.
  • the feed channel becomes narrower as the flow path increases.
  • the free cross-section or open channel cross-section can preferably be increased or decreased by up to plus / minus 100%; in particular, the free channel cross-section of the feed channel with pin can be compared to the cross-section of the feed channel (channel cross-section without pin ) can be reduced by at least 1% to preferably 100%.
  • the free channel cross-section through the at least one pin can preferably be set from 0% to 100% by changing the position of the pin, in particular from 5% to 90%, particularly preferably from 5% to 25%.
  • the free cross section of the feed channel which results from the cross section of the feed channel without pegs minus the cross section of the at least one peg, can be set by the relative position of the at least one peg in the feed channel, the position of the at least one peg from the relative rotationally symmetrical position of the chamber part and closure part depends.
  • the relative position of the at least one pin in the feed channel depends on the relative rotationally symmetrical position of the chamber part and the closure part.
  • the flow resistance can thus also be varied.
  • one of the possible relative rotationally symmetrical positions of the chamber part and the closure part is selected as a function of the viscosity of the dental materials and is fixed by welding.
  • the concept does not provide for any mixers that can be individually set by the user for different pastes. Rather, the concept of the relative rotation of the chamber part and the closure part to one another enables an adaptation to the respective viscosity of the pasty masses. Once the optimal position of the pin and feed channel has been found, the positioning of the two components to one another is fixed by welding. Should the viscosity of the pasty masses change or a new product with a new viscosity should be added, the new, optimal mixing quality could be restored with the existing unwelded components by means of a new shift on the pitch circle of the two components to each other. Ideally, this could be solved by adjusting the assembly machine. Expensive and time-consuming adaptations and tests of the injection molding tools would be avoided.
  • the first inlet opening is followed by the straight channel, which leads directly into the mixing chamber without detours
  • the second inlet opening being followed by the feed channel which, via a detour between the at least two axially parallel planes of the closure part in guides the mixing chamber, the rectilinear channel being designed to transport a first volume flow, the feed channel being designed to transport a second volume flow, the second volume flow being between 100% and 10% of the first volume flow.
  • the respective connecting channel between the feed bore and the mixing chamber is designed in connection with the flow barrier in such a way that at least one of the at least two volume flows results in between 100% and 10% of the volume flow without throttling.
  • the invention also relates to a method for producing a dynamic mixer, in particular for dental materials of different viscosity, wherein the method can comprise the following steps:
  • the method comprises the steps: f) filling the dynamic mixer with the dental materials with different viscosities at the first and second inlet openings;
  • a relative position of a partition to the feed channel changes, the partition being part of the chamber part or part of the closure part, the partition separating the feed channel from the mixing chamber, the partition being on a further inner Partial circle or runs on an inner ellipsoidal path of the feed channel.
  • the path in the feed channel to the passage opening to the mixing chamber, in particular for dental materials is that long. If the partition wall forms a relatively long inner wall of the feed channel, the longer the path from the inlet opening of the feed channel through the feed channel to the passage opening into the mixing chamber. If the partition wall forms a relatively short inner wall of the feed channel, the shorter the path from the inlet opening through the feed channel to the passage opening into the mixing chamber.
  • a relative position of at least one pin which protrudes with its longitudinal axis into the feed channel, changes relative to the feed channel.
