<p>The mixing device for mixing of binding component (A) and curing component (B) to obtain a pasty or liquid mixed product, comprises inlet openings for supplying the components, discharge openings for delivering the mixed product, and a mixing chamber for the components arranged between the openings. The mixing device exhibits a hollow cylinder stator part, which concentrically revolves around longitudinal axis of rotor part. The mixing chamber forms an annular gap between the stator portion and the rotor portion. The mixing device for mixing of binding component (A) and curing component (B) to obtain a pasty or liquid mixed product, comprises inlet openings for supplying the components, discharge openings for delivering the mixed product, and a mixing chamber for the components arranged between the openings. The mixing device exhibits a hollow cylinder stator part, which concentrically revolves around longitudinal axis of rotor part. The mixing chamber forms an annular gap between the stator portion and the rotor portion. The stator part whose end that faces away from the inlet openings, carries a ring-shaped holding device, which exhibits fastening openings and a solvable bayonet lock connected to the rotatable stator part limited by stop in such a manner that the stop is achieved simultaneously with supply of binding component and the curing component by means of a fit. A mixing tooth is formed radially at the stator part and at the rotor part. A second mixing tooth extends radially outward into the mixing chamber. The mixing tooth is oppositely moved in the stator part by means of rotational movement of the rotor part. The tooth is arranged on the first- second mixing tooth level. The number of mixing tooth levels is equally intended at the rotor part and/or at the stator part. The components are supplied to the mixing chamber by means of control devices in such a way that the curing component is fed to the mixing chamber slightly higher that the binding component. The plastic or metal ring-shaped holding device exhibits two arc-shaped, slot- shaped openings that are oppositely arranged parallel to rotary edge of the holding device, in which each of the slot- shaped openings exhibit two guidance sections with different widths. Each of the width guidance sections is formed for introduction of L-shaped guidance cams at the lower rotary edge of the stator part. The width of the guidance section corresponds to the length of the free angle of lower legs and each of the narrower guidance section exhibits a width. The strength of the stator part is formed at the lower rotating edge and parallelly corresponds to the longitudinal direction of the mixing device of lower legs of the L-shaped guidance cams. The slot-shaped openings exhibit outer wall area of the narrower guidance sections respectively by forming tongue-like boundary areas and web-like wall sections, so that a groove-like recess is formed. The number of L-shaped guidance cams is larger than two L-shaped guidance cams. The mixing tooth exhibit front-side faces. The inlet openings are arranged into the mixing chamber for supplying the curing-component to form a redundant supply of the mixed product with the curing component. The rotor part exhibits end-sided projections, which project into the inlet opening for the supplying the binding component and rotate with the rotation of the rotor part to reduce the thixotropy of the binding component in the supply channel of the inlet opening. The rotor part exhibits an end-sided open, hollow cylinder-like recess, in which a geometry-adapted core is applicable, is propellable by means of its rotor part. The recess of the body of the rotor part exhibits radially locking ribs, which correspond into appropriate recesses in the core, to transfer the driving torque for operating the mixing device of the core. The rotor part exhibits sealing lips to seal the mixing chamber between the rotor part and the stator part and to prevent the exit of the mixed product. The stator part exhibits a plate-shaped element at the outer circumference. The element comprises a crescent-shaped stop contour, in which the mixing device inserts a pin element to secure the radial position of the discharge opening in the stator part. The rotor part exhibits a cylinder-shaped bearing section to form a slide bearing arrangement. The stator part comprises a supporting bearing surface in which the rotor part adjoins and glides off at the formed front-sided mixing tooth around an axial sliding bearing arrangement. A cavity is formed between the lips to collect the mixed product that is enabled through the sealing lips. The stator part exhibits discharge opening in the cylindrical section of the cavity, to prevent the removal of mixed product from the cylinder-shaped bearing section. The discharge opening is carried out as a circle discharge opening on a sidewall section of the stator part. The size of the discharge opening is dimensioned in such a way that 100 g ready-made filler substance is delivered essentially in 10 s. An independent claim is included for equipment for producing a ready-made filler for filling the surface of vehicle bodywork.</p> |
