(54) DEVICE FOR DRAWING PAINT ON FLAT

SURFACE

call and therefore, good quality appearance of the surface of the material.

In order to intensify the splitting of the ink jets and to improve the quality of the colors HJB with the proposed device, the elements are dissected in vice spirals of conductive material connected to the current source.

FIG. I shows a general view of the device; Fig, 2 is a cross section of the device.

The device for applying paint on flat surfaces consists of a bath 2 mounted on the bed I, fixed on the axis 3 of the metering roller 4 ,. connected to the drive 5 of its rotation, the blade of the knife 6 in contact with the cams 7 fixed to the axis 3 of the metering roller 4 and provided with trays 8 | long jetting the paint from the bath 2, and the mechanism for dissecting the jet of paint, made in the form of hingedly mounted on: axles 9 on the bed 1 of the rocker arms 10, at the ends of which are fixed on the axes 11 of the frame 12 with spirals 13. For ensuring one-piece movement of the frames 12 one of the rocker arms 1O interacts with the eccentric 11 fixed on the bed I, and the other spring-loaded relative to the bed I with the help of the spring 15. The helix 13 of the conductive material is tensioned perpendicular to the length of the frames 12 and connected. with a current source of 16.

The operation of the device is as follows:

When the dosing roller 4 OKpaco4iiCbifl is rotated, the bath 2 is fed to the movable knife 6, which receives a reciprocating movement along the roller 4 from the cams 7 and removes the paint from the dosing roller 4. Then the paint flows down in thin streams along the trays 8 of the knife 6 and cuts off the spirals 13 of the frames 12 as a result of their shuttle movement perpendicular to the paint. The frames 12 with the spirals 13 are driven from the eccentric 14, which acts on one of the rocker arms 1O, the reception, if the upper one of the frames 1.2 is shifted to the left, then the lower one - to the right.

Dissected streams of paint in the form of droplets of various sizes randomly fall

and the moving material 17 to be processed creates a patchy pattern on it. Adjusting the viscosity of the falling drops of paint, as well as cleaning the spirals 13 by annealing them when switching to another

Ink paint is achieved in the device due to the constant connection of the spirals I3 with the source of sa 16c, possible 1M voltage regulation from 0 to 38 Oh. This makes it possible to obtain the required temperature of the spirals 13 in the range from temperature (ambient medium to 5OO ° C. Spirals can be made, for example, from nichrome.

As a result of the use of

good dispersion of paint droplets is achieved and their random distribution over the surface of the material being processed is provided, imitating the natural color of the material and

giving it a good decorative qualities.

F o r Mula Invention

A device for applying paint on a flat surface containing a bath with a metering roller partially immersed in a dyeing composition, a movable knife with trays and a jet dissection mechanism

paint, made in the form of a framework with the possibility of shuttle movement with the cutting of elements, characterized in that, in order to intensify the splitting of the paintworks

improving the quality of coloring, the dissecting elements are made in the form of spirals not of the conductive material connected to the current source.
