SU664694A1 - Chamber for painting rollers of belt conveyers - Google Patents

Description

one

The invention relates to the field of the application of protective anti-corrosion coatings, in particular to devices for painting or preserving.

Designs are known for dyeing chambers in which paint is applied by spraying, as well as a dyeing chamber in an electric field 1.

When painting the belt conveyor rollers in these chambers, it is necessary to pre-isolate the surfaces that are not subject to painting, and low productivity is noted.

Also known is a camera for painting rollers of belt conveyors, containing a chain conveyor for moving the rollers to be painted, a bath with a dye material and a mechanism for applying it 2.

Such a camera is the closest to the invention of the technical essence to the achieved result.

The disadvantage of it is that it does not provide high performance, which depends on the speed of the roller and the speed of the conveyor. Increasing the conveyor speed requires an increase in the revolutions of the roller, which cannot be increased due to splashing of the paint under the action of centrifugal forces. During the painting process, the contact of the roller with the roller occurs along a spiral line, and the resulting painted surface of the roller has an uneven coating that is larger towards the center line of contact and decreases as it moves away from it.

The location of the roller axis at an angle of 30 ° to the axis of the roller during operation causes a constant impact on the roller of axial force, which in turn is transmitted to the conveyor chain, which reduces its reliability and durability.

The aim of the invention is to improve the performance of the camera, its durability and reliability and to obtain a uniform coating.

This goal is achieved by the fact that the mechanism for applying the coloring material is made in the form of a horizontally positioned endless belt pulled over drums covered with a porous material passing through a bath of paint material, with the upper branch of the endless belt parallel to the supporting branch of the chain.

A roller conveyor dyeing chamber contains a chain conveyor 1 for moving the painted rollers 2, a bath 3 with a coloring material and a mechanism for applying it, made in the form of a horizontally sprawled endless belt 4, pulled on the drums 5 and 6 covered with a porous material and a passage through the bath 3 with the dye material, the upper branch of the endless belt 4 parallel to the carrier branch of the chain conveyor 1 and located on the bed sheet 7. The bath 3 is mounted inside the rectangular frame 8, the common sheet by steel. Prisms 9 are used for stacking rollers. Drive drum 5 has a smaller diameter than tension drum G to tilt the lower part of the branch in order to immerse it incompletely in bath 3. Endless belt 4 and chain conveyor 1 have individual drives 10 and 11. Chamber For dyeing roller conveyor belt works as follows. When the conveyor 1 moves with the rollers 2 to be painted, the latter rolls onto the tape 4 that is moving towards them and supported by the underlay 7 and moistened with the coloring material. The rollers 2 roll around on the tape 4 with the same specific pressure over the entire surface wetted in the dyeing material, which ensures uniformity of the coating and thereby improves the corrosion resistance of the rollers during storage, which increases by a factor of 2-3. When the roller rolls around the tape, only the radial force acts on it, while the action of the axial force is completely eliminated at this mutual arrangement of the tape and roller, which does not create additional loads on the conveyor chain, and therefore increases its reliability. DETAILED DESCRIPTION OF THE INVENTION Camera for painting rollers of belt conveyors, comprising a chain conveyor for moving the rollers to be painted, a bath with a coloring material and a mechanism for applying it, characterized in that, in order to increase the performance of the camera, its durability and reliability and to obtain a uniform coating the dye material is made in the form of a horizontally placed endless belt, pulled over the drums, covered with a porous material and passing through the bath with the dye material, while it upper branch of the endless belt is parallel to the support arm of the chain conveyor.
