Abstract
The invention relates to a machine for stirring paints. This machine is of the type comprising support racks (3) of cans of tints provided with an upper stirrer lid (5), and a mechanism for driving the stirrer lids on each of the racks, the stirrer lids (5) each being provided with a motion take-up pinion (27) for the stirrer shaft inside the cans. It is characterized in that said mechanism for driving the stirrer lids brings into play a set of endless screws (29) mounted one on each of the racks, these screws each coming to mesh with the driving pinions (27) of the stirrer lids of a same rack and being driven at an adequate speed of rotation, which is variable depending on the range of the cans of tints of the racks.

Stirring machine for paints, comprising support racks (3) for cans of tints each provided with an upper stirrer lid (5), a mechanism for driving the stirrer lids on each of the racks, a stirrer shaft in each said can, the stirrer lids (5) each being provided with a motion take-up pinion (27) for operatively engaging the stirrer shaft of respectively each of the cans, said mechanism for driving the stirrer lids actuating a set of endless screws (29) mounted one on respectively each of the racks, said endless screws each meshing with the pinions (27) for driving the stirrer lids of a specific rack and being driven at a variable speed of rotation in dependence upon the range of the cans of tints of the racks.
Stirring machine as claimed 1, wherein the speed of rotation of the stirrer lids (5) of the cans of lacquers is obtained by varying the following parameters:
- number of teeth of the driving pinions (27) of the stirrer lids, screw-pinions (29, 27) reduction factor and use of a primary transmission of low reduction by belt or by chain, it being possible to produce the speed reduction by the set of pulley diameters of the motor in such a manner that the suitable speed of rotation of the stirrer shafts of the lids is maintained.
