DESCRIPTION:
BRIEF SUMMARY
1. Technical Field
The object of this invention is a basket for the machines to mix, grind several substances in an excellent way, especially for the creation of paints.
When producing paints, especially paints for cars, it is very important that the mixing of the various components is done in a very refined way. For such purpose the basket as by this invention uses mixing balls featuring a very small diameter which are inserted into a basket equipped with an internal channel with walls perforated with small holes, in which, in order to increase the mixing and grinding qualities of the microballs there are vertical fixed carried by a disc equipped with vertical cuts against which these microballs hit. The upper surface of the basket is closed by a lid so that the products to be mixed is sucked into the basket through the walls perforated with small holes.
2. Background Art
There have long existed machines capable of mixing and grinding the elements that go into producing paints for the purpose of obtaining a uniform mix. These machines, created according to a variety of designs, have been placed under the protection of a number of patents, both Italian and foreign, by the same enterprise proposing the present patent application.
In an earlier patent, held in Italy (1,211,658), Europe (89830011.6) and the United States (U.S. Pat. No. 4,967,968) by the same enterprise, a description was given of a machine used for the simultaneous dispersion, mixing and grinding of a number of substances in order to obtain uniform mixes of a pre-established granular density, such as those employed in producing paints. The underlying principle for the operations of such a machine is the face that the elements which go into the production of the paint, meaning the film-generating substances, the pigments, the diluents, the plasticizers, the drying elements and other potential components, are introduced in appropriate doses into a receptacle and agitated inside a perforated basket which contains a mixing element and numerous marbles or other elements made from glass or from suitable materials. But although this machine make it possible to obtain excellent mixtures, it is not capable of turning out, in short periods of time, a product which meets the demands of the more difficult finishing processes, such as paints for automobiles and similar uses.
This difficulty is traceable to the fact that the basket in the traditional machine must operate using spheres which are excessively large.
One solution to the problem would be to insert spheres of a much smaller diameter in the basket. In this case, however, the size of the holes on the basket walls would also have to be reduced, and it has been found that, with smaller holes, the temperature of the material inside the basket becomes excessively high, due to the slow rate of exchange of the paint.
DISCLOSURE OF INVENTION
The subject of the present invention is a basket for machines used to mix and to grind a number of substances in order to obtain uniform mixes, such as those used to produce paints, capable of resolving the aforementioned inconveniences, and, therefore, permitting the production of paints for highly-refined finishing work in very short periods of time.
The basket proposed in the present invention has the external form of a circular ring bounded both inside and outside by a circular surface perforated with small holes, while the central, upper portion, when viewed from above, is closed off by a circular element with a small, central slot; in effect, the basket, when viewed from above, and without the other elements which complete the assembly, has the appearance, as mentioned earlier, of a circular ring, with the ring forming a channel whose walls are perforated with small holes; when viewed from below, on the other hand, the outer channel proves to be closed, while the central portion is occupied by a space which is empty, but closed at the top.
A fixed disc, or similar structure, is attached to the internal shaft, which is coaxial to that of the machine. This dis
