Embodiment Construction

[0031] figure 1 A rotary atomizer 1 according to the invention is shown, which can be used, for example, for painting bodywork components of a motor vehicle, wherein the rotary atomizer 1 is generally constructed in a conventional manner, so that the construction of the rotary atomizer 1 can be dispensed with and a detailed description of its efficacy. For the description of the invention, it is only important that the rotary atomizer 1 has a paint tube 2 fixed on the connection module 3, wherein the paint tube 2 is aligned coaxially with the axis of rotation of the bell cup shaft 4 for Send the coating agent to be applied.

[0032] The invention provides that the grid mixer 5 is arranged in the paint tube 2 in order to mix the various components of the coating agent (for example primer and hardener / curing agent) with one another.

[0033]The grid mixer 5 has a plurality of elongated, rod-shaped, sharp-edged mixing elements 6 arranged in a grid-like arrangement, wherein the ...

Abstract

The invention relates to an atomizer (1), in particular to a rotary atomizer for applying a coating composition consisting of several components, with a Static mixer (5) for mixing together several components, wherein the mixer (5) has several fixed mixing elements (6) and is structurally integrated in the atomizer (1). The mixer ( 5 ) is proposed to be a grid-type mixer in which the mixing elements ( 6 ) are arranged intertwined in a grid-like manner.

Description

technical field [0001] The present invention relates to atomizers, and more particularly to rotary atomizers for applying coating compositions consisting of multiple components. Background technique [0002] In modern painting plants for painting automotive bodywork components, rotary atomizers are traditionally used as application devices, rotary atomizers can sometimes also apply multi-component paints, where the Multi-component paints consist of various coating agent components such as primers and hardeners. Here it is important that the various components of the multi-component paint mix with one another as well as possible in the atomizer. For this purpose, conventional rotary atomizers have static screw mixers, which are also called mixer. A helical mixer has a plurality of helical mixing elements, wherein the helical mixing elements direct the flow of coating agent radially outwards and then back into the center. Usually, two separate screw mixers are used, the f...
