The present invention relates to a static mixer for mixing together at least two components. The static mixer comprises a mixer housing; a mixing element having an upstream end with at least two entry openings and a downstream end, the mixing element being arranged at least partly within the mixer housing; a mixing head having at least two inlets provided at an input side and at least two outlets provided at an output surface, wherein each of the at least two inlets is in fluid communication with one of the at least two outlets; and a separating wall disposed between the output surface and the upstream end of the mixing element for separating the components leaving the outlets. The separating wall comprises a free downstream edge which is disposed with respect to at least one of the entry openings so as to allow at least partial flows of the components separated by the separating wall to combine after exceeding the downstream edge and to jointly enter said at least one of the entry openings.

The disclosure relates to a preferably automated change system for changing a mixer, comprising a mixing device, having a mixer, for mixing at least two different components for a multi-component application agent for application onto a workpiece, and a handling device for moving the mixing device, wherein the change system comprises a change station for depositing a mixing device with a mixer to be changed and preferably for receiving a mixing device with a new mixer. The disclosure relates also to a corresponding changing method.

A viscous material stirring apparatus includes a stirring member that rotates about a rotation axis and has a tip radially separated from the rotation axis, a rotary actuator that rotates the stirring member about the rotation axis, a moving mechanism that moves the stirring member, and a control device. The control device drives the moving mechanism to immerse the tip of the stirring member into an applied viscous material, drives the rotary actuator to rotate the stirring member around the rotation axis, and drives the moving mechanism to move the stirring member along a coating direction of the viscous material with the tip of the stirring member immersed in the viscous material.

An aerated wax application assembly comprises a meltable wax applicator, one or more meltable wax delivery conduits having a first end coupled to the meltable wax inlet of the meltable wax applicator and a second end positioned proximate a meltable wax holding tank, and an air injection system positioned upstream from the meltable wax applicator and configured to inject air into the meltable wax and generate the aerated meltable wax upstream of the inlet of the meltable wax applicator. A method of applying an aerated meltable wax onto an object comprises injecting air into a meltable wax such that it forms an aerated meltable wax, delivering the aerated wax through one or more meltable wax delivery conduits to a meltable wax applicator, and contacting at least one exposed surface of the object with the aerated wax when dispensing the aerated meltable wax from an outlet of the meltable wax applicator.

An adapter for improving the efficiency of a static mixer being used to mix reactive fluids such as epoxy adhesives. This allows either a small static mixer to be employed, or a smaller purge flow during dispensing operations.

A modular continuous mixer includes a rigid casing having an inlet adjacent to an annular inlet end thereof and an outlet adjacent an opposing annular outlet end thereof. The casing further includes a cylindrical exterior casing wall that, together with the ends, define a volume therein. The ends each include a plurality of concentric rings of mixing pins projecting into the volume. One or more rotor disks are rotationally fixed within the casing between distal ends of the opposing pins. Each rotor disk includes a plurality of the concentric rings of mixing pins projecting from both sides thereof toward the inlet and outlet ends. A drive shaft is rotatably mounted in the casing and fixed through the center of each rotor disk. Additional casing extensions can be mounted between the inlet and outlet ends of the casing to facilitate further mixing.

A dynamic mixer for a dynamic mixing operation for mixing a liquid or paste-like product, in particular a multi-component product, comprising a core element, a first blade element integrally formed with the core element and helically extending around the core element in a first helix direction, and a second blade element integrally formed with the core element and helically extending around the core element in a second helix direction that is different from the first helix direction, wherein the first blade element and the second blade element are arranged immediately adjacent when viewed in a longitudinal direction of the mixer, the first blade element having a first blade element height, when viewed in the longitudinal direction, and the second blade element having a second blade element height, when viewed in the longitudinal direction that is different from the first blade ele-ment height.

A two component adhesive system pumps a first adhesive component and a second adhesive component into a replaceable mixing unit that can be periodically replaced when the adhesive has cured in the mixing unit. The adhesive system has a robotic arm coupled to a gripper unit which has an open position and a closed position. In the open position, the gripper unit releases the mixing unit allowing the mixing unit to be replaced. The robotic arm moves the gripper unit to install a replacement mixing unit. The gripper unit can be moved to the closed position and the adhesive can be pumped through the mixing unit.

Mixing device and applicator for sealants formed by a main body and a handle (1), wherein the main body comprises a container-carrying sheath (7), a rotating cylinder (14), a gear module (11) that can be coupled to a rotor and a set of mechanisms that eject the sealant material. By actuating a trigger (2), a speed regulator (3) and a rotation selector (4) present in the handle (1) in a first action the cylinder (11) rotates in one sense mixing the material and in a second action it changes the sense of rotation and by actuating a cylinder locking system (19 and 20) present in the main body the device ejects the sealant material.

A mixer unit comprising a mixing chamber comprising a de-agglomerator with a de-agglomeration shaft with de-agglomeration means, a mixer with a mixer shaft with two or more mixing paddles, arranged for mixing and impelling particles and powders in an upstream direction towards the de-agglomerator wherein said de-agglomeration shaft is arranged above, and in parallel with said mixer shaft, so that all particles will be impelled towards the de-agglomerator, each time particles are lifted. Further said mixing chamber comprising a first portion of said mixing chamber having an inner profile adjacent and curved about an upper part of said de-agglomerator and arranged to guide particles and powders impelled by said mixing paddles over said de-agglomeration shaft and into a liquid spray.
