Dispensing machine for the metered delivery and contimuous homogenization of finished paint products

Abstract

A dispensing machine for the metered delivery of fluid products, especially painting products, comprises a dispensing head (13) with a nozzle (13b), with which the ends of a plurality of delivery ducts (10) communicate in order to feed a corresponding plurality of fluid products. Mixing means, in particular a rotating turbine (20), are mounted between the ends of the delivery ducts (10) and the dispensing nozzle (13b) to continuously mix the fluid products coming from the different delivery ducts and simultaneously entering the dispensing head (13).

Description

technical field [0001] The present invention relates to a dispensing machine for dosing fluid products, in particular for dispensing fluid ingredients that make up finished products such as paints, coatings, inks, enamels, textile dyes and similar finished products. Background technique [0002] In order to manufacture the finished products as exemplified above, it is known to add one or more coloring fluid ingredients in defined proportions to a base fluid, such as a white or clear fluid, according to a specific formulation. Known machines used in the above-mentioned industries dispense known quantities of colorants into volumetric tanks, containers, tins or boxes into which the base fluid formulation has previously been placed. These known machines must ensure a high degree of accuracy in dispensing the amount of colorant ingredients, because even slight differences in the relative proportions between the various colorant ingredients or between these colorant ingredients a...

Problems solved by technology

These known machines must ensure a high degree of accuracy in dispensing the amount of colorant ingredients, because even slight differences in the relative proportions between the various colorant ingredients or between these colorant ingredients and the matrix fluid ingredients will cause the final product to be distorted. The color of the product does not match the desired effect

Also, after dispensing with conventional dispensers, the distribution of the coloring ingredient in the bulk of the base fluid ingredient is uneven, requiring more or less vigorous shaking of the jar

In the process of producing the final product by the so-called toning method, this necessary shaking step is obviously laborious, because this operation requires additional manual operations or the use of special mixers. and heavy, are often difficult to handle, thus increasing the cost of the method

And, in any case, the mixing operation also significantly increases the production time of the final product

[0003] Therefore, at the current level of technology, the homogenization step is the bottleneck step of the production efficiency of the rapid compounding machine, and this homogenization step makes this color mixing method only applicable to ingredients with good fluidity, and does not allow the use of ingredients containing a large amount of solids or highly viscous ingredients for microplastics
