    专利说明:

    The present invention relates to a mixing device having the features of the preamble of claim 1.
    The invention is particularly preferred for use in the production of foamed plastics (e.g., in the form of plastic gaskets). In order to achieve a desired microstructure of the plastic, it is necessary that in the mixing device there is a pressure located in a certain pressure window. If a gas loading of one of the two liquid plastic components is provided, the specific pressure window also depends on the gas loading. If the desired amount of discharge from the discharge opening varies, the quality of the microstructure of the foamed plastic can vary greatly.
    It is known that variations in the temperature or viscosity of the first and second liquid plastic components as well as by contamination in the mixing device can lead to changes in the quality of the microstructure.
    There are therefore already measures known to stabilize the temperature, remove contaminants and keep the viscosity constant and to use different nozzles to adapt different discharge rates. Thus, in DE 42 35 850 B4 discloses a generic mixing device, the stirrer performs a dual function, namely on the one hand the stirring function and on the other hand, the closure function of the discharge opening. To fulfill the closing function, the stirrer can be raised and lowered in a mixing chamber of the mixing device. In order to be able to adapt to different discharge quantities, the outlet nozzle housing is replaceable.
    In EP 1 123 180 Bl a generic mixing device is also shown, the stirrer fulfills a dual function as a stirring device and closure device. To avoid sudden onset or closing movements of the stirrer, which can cause quality deterioration in the processing of sensitive materials produced by the milled mixture workpieces, the drive unit for raising and lowering the stirrer is equipped with a cam drive, the actuating cam with a cam shape steady or jerk-free course has.
    The previously known mixing devices have not dealt with the quality of the microstructure of the foamed plastic from the mixture, so that they can vary greatly in part when using the known mixing devices.
    The object of the invention is that a consistent quality of the microstructure of the foamed plastic is achieved.
    This object is achieved by a mixing device having the features of claim 1.
    The invention is based on the surprising finding that a constant quality of the microstructure of the foamed plastic is automatically reached by keeping constant the pressure in the mixing device, as changes in the discharge, fluctuations in temperature, viscosity of the first and second liquid plastic components, soiling unpredictably affect the pressure in the mixing device, are ausregelbarer.
    The amount of pressure in the mixing device depends, inter alia, on the size of the gap between the stirrer and the discharge opening and on the size of the discharge opening. Other factors influencing the pressure, such as the dimensioning of the nozzle can be considered constant. By determining the pressure prevailing in the mixing device and adjusting the gap or the size of the discharge opening by means of sensor, control device and adjusting device, the pressure in the mixing device can be adjusted to a desired predetermined value and kept substantially constant.
    The proposed mixing device is particularly advantageous when the mixing device is operated in the low-pressure region at a pressure prevailing in the mixing device of less than about 20 bar. In this pressure range, a gas present, for example, in the first liquid plastic component - e.g. air dissolved in polyol - already in the mixing chamber. That already in the
    Mixing chamber bubbled gas serves as a condensation germ and ensures a uniform foaming of the mixture when discharging from the mixing device.
    It has been found through experiments that the proposed mixing device can achieve a consistent microstructure for a wide range of different discharge rates. For example, when the application rate was doubled or tripled, a substantially unchanged microstructure and thus a constant quality of the microstructure could be achieved.
    The first liquid plastic component may preferably be a viscous liquid. Examples are polyols, silicones, epoxy, polyesters, acrylates and MS polymers.
    Examples of the second liquid plastic component are isocyanate and silicones.
    Examples of the gas with which the first and / or second liquid plastic component may be mixed are air, nitrogen, carbon dioxide.
    It can be provided that the gas is at least partially dissolved in the first and / or second liquid plastic component.
    Further examples of systems with at least 2 components are: addition-curing silicone with silicone as the first liquid plastic component and silicone as addition-crosslinking crosslinking agent condensation-crosslinked silicone for example. B. with water and / or glycols, or according to DE 10 2008 011 986 AI with silicone as a viscous liquid and water and / or glycols as a crosslinking crosslinking agent • polyurethane (result) crosslinked with isocyanate as a curing agent. The polyol component as a liquid may, for. As polyester polyols, polyether polyols, thiols, glycols, amines, chain extenders and acrylates. The isocyanates may be aromatic (e.g., based on MDI, TDI) as well as aliphatic (e.g., based on HDI, IPDI, 12-fold hydrogenated MDI). • Polyisocyanate, the second component contains the trimerization catalysts and possibly polyols, other substances with active hydrogen or non-reactive thinner. • 1K NCO-terminated polyurethanes with water and / or glycols as curing or crosslinking agents (booster systems) • Epoxy resin systems • Silane-modified polymers with water and / or glycols in the B component, e.g. MS Polymers • Acrylates, radically cured • Unsaturated polyester resins, free radical cured • Vinylester resins, free radical cured
    According to a preferred embodiment it can be provided that the stirrer is designed to be movable relative to the discharge opening. It can be provided that the adjusting device is connected to the stirrer, wherein the agitator is movable relative to the discharge opening by the adjusting device.
    It can be provided that the adjusting device comprises a linear motor, which is preferably arranged on a shaft of the stirrer.
    It can be provided that the discharge opening is designed to be variable in size. It can be provided that the adjusting device is connected to the discharge opening, wherein the adjustment of the size of the discharge opening is variable. The adjusting device may be formed, for example, as an iris-like diaphragm, wherein the discharge opening is formed by the remaining free central region of the iris diaphragm. Alternatively, the adjusting device may be formed as an elastic element in the manner of a hose clamp, wherein the discharge opening is formed by the remaining free width in the hose.
    If the mixing device is elongated, it can be advantageous if the at least one feed opening for the at least one first liquid plastic component and the at least one further feed opening for the at least one second liquid plastic component at different axial positions of the
    Mixing device are arranged. Because the mixing of the two liquid plastic components takes place only in the region of that feed opening which is closer to the discharge opening, there is no or only little contamination in the area lying axially above it.
    It can be provided that the discharge opening of the mixing device is connected to a nozzle.
    It can preferably be provided that the predetermined value for the pressure prevailing in the mixing device is less than 20 bar, preferably less than 10 bar, particularly preferably about 2 to about 4 bar.
    Protection is also desired for an arrangement having a mixing device according to at least one of the preceding embodiments and a source for the at least one first liquid plastic component connected to the at least one feed opening for the at least one first liquid plastic component, preferably the at least one first liquid plastic component Plastic component is mixed with a gas, and a source for the at least one second liquid plastic component, which is connected to the at least one further feed opening for the at least one second liquid plastic component, wherein preferably the at least one second liquid plastic component is mixed with a gas.
    Embodiments of the invention will be discussed with reference to the figures. Show it:
    Fig. 1 shows a first embodiment of an inventive
    Mixer,
    Fig. 2 is a detail view of the mixing device of FIG. 1 and
    Fig. 3 shows a second embodiment of an inventive
    Mixing device.
    Fig. 1 shows a mixing device 1 with a mixing chamber 12. There is a feed opening 2 for at least a first liquid plastic component (for example polyol) and a further feed opening 3 for at least one second liquid
    Plastic component (e.g., isocyanate) leading into the mixing chamber 12. The mixing device 1 is designed dynamically and comprises a stirrer 7, which is rotatable in the mixing chamber 12. The first and / or the second liquid plastic component may be combined with a gas - e.g. Air - be mixed.
    To produce the first and second liquid plastic component mixture, the first liquid plastic component blended in this example with air and provided by a source 10 is supplied through the first feed opening 2 and the second liquid plastic component provided by another source 11. introduced through the second feed opening 3 at different axial positions of the mixing device 1 formed here elongated here. By the rotating stirrer 7, it comes to mixing these two components.
    Adjacent to the tip of the stirrer 7 is a discharge opening 4 for discharging the mixture consisting of first and second liquid plastic component from the mixing chamber 12 is provided. Via a remaining between stirrer 7 and discharge opening 4 gap 6, the mixture of the discharge opening 4 in the direction of a nozzle 9 can be discharged.
    An adjusting device 5 is provided, by means of which a relative movement between dispensing opening 4 and stirrer 7 can be caused and thus the gap 6 between stirrer 7 and dispensing opening 4 can be changed. The adjusting device 5 has a stepping motor, which engages via a shaft in a toothed wheel, which engages laterally in a concentric with the shaft 16 arranged screw sleeve. A rotation of the gear by the stepper motor causes an axial adjustment of the screw, whereby the height adjustment of the stirrer 7 takes place, which adjusts the gap between the stirrer 7 and discharge opening 4. About the scale shown schematically, a measurement of the adjustment made done and reported to the control device 14 (the corresponding signal lines are not shown). During the dosing air is introduced in the direction of the arrow schematically shown in the area above the seal 15, which leads to a lifting of the stirrer 7 against the action of the energy accumulator 8 to the stop defined by the screw. If the air pressure is switched off, the force accumulator 8 moves the stirrer 7 so far in the direction of the discharge opening 4 (downwards in this illustration) until the stirrer 7 closes off the discharge opening 4.
    In order to determine a pressure prevailing in the mixing device 1 or its mixing chamber 12, a sensor 17 is provided which is in signal-conducting connection via a signal line 18 with a regulating device 14. The control device 14 in turn is connected via a control line 19 with the adjusting device 5 in signal-conducting connection, so that the control device 14 via the adjusting device 5, the gap 6 can set such that the prevailing in the mixing device 1 and the mixing chamber 12 pressure a predetermined value, for example less than 20 bar. As an alternative to the positioning of the sensor 17 shown, other positions are conceivable, e.g. in the line 10.
    In the present embodiment, the pressure conditions are selected so that it comes in the mixing chamber 12 to a constant pressure which is low enough that a foaming agent present in the mixture can foam.
    If the pressure in the mixing device 1 or its mixing chamber 12 changes during or after a dispensing operation of the mixture from the mixing device 1, this pressure change can be detected via the sensor 17 and the control device 14 can control the adjusting device 5 such that this pressure change a corresponding relative movement between the stirrer 7 and discharge opening 4 is counteracted and the desired predetermined pressure in the mixing device 1 is maintained. In particular, a corresponding pressure adjustment can take place after each dispensing operation or after each dispensing.
    A seal 15 (which can be sealing in one direction or in both directions) sealingly encloses the rotating shaft 16 of the agitator 7 and seals the mixing chamber 12 in the region of the shaft 16 of the agitator 7. The seal 15 may for example consist of Teflon and allow smooth axial movement of the rotating shaft 16. Because the shaft 16 rotates and the seal 15 causes low friction, a very fine axial positional adjustment of the agitator 7 can be achieved. In particular, unwanted pressure fluctuations by jerky axial displacement of the stirrer 7 due to a
    Stick-slip effect can be avoided. By the rotation of the shaft 16 and the axial displacement of the stirrer 7 is facilitated. Preferably, the seal 15 is formed as a rotational and translational seal.
    FIG. 2 shows a detailed view of the tip of the stirrer 7 of the mixing device 1 according to FIG. 1 in a changed operating state, in which the stirrer 7 has been moved axially relative to the discharge opening 4 so far that it closes the discharge opening 4. The tip of the stirrer 7 is formed sharper than the inclination of the end face 13 of the mixing chamber 12. Thus, the tip of the stirrer 7 is only annular on the end face 13 and protrudes into the discharge opening 4 in order to complete this annular.
    In contrast to the embodiment according to FIG. 1, in this case the adjusting device 5 comprises a linear motor arranged on the shaft 16 of the stirrer 7, which can directly raise and lower the stirrer 7 axially and thus the required Relative movement between the stirrer 7 and discharge opening 4 can cause to change the gap 6 to the extent required, so that in the mixing device 1 and the mixing chamber 12 prevailing pressure has the desired predetermined value. About the scale shown schematically, a measurement of the adjustment made done and reported to the control device 14 (the corresponding signal lines are not shown).
    Unlike illustrated, the adjusting device 5 may include, for example, a known cam drive, spindle drive or hydraulic drive.
