Description

The invention relates to painting equipment and can be used in any branch of industry, for example, in automotive equipment in spray painting plants with a continuous overhead conveyor.

The aim of the invention is to save production space and improve the quality of coatings.

1 is a schematic representation of the installation, a plan view; in FIGS, section A-A in FIG.

The spray coating unit contains a common chamber 1 in which the inlet vestibule and steam tunnel are combined, the chamber 5 pouring over the spray unit 3 with the nozzles 4, the conveyor 5 with the rotary device 6 for transporting products 7, the pump 8, the tank 9 for paint and varnish material and the U system recycling solvent vapors connecting the common chamber 1 with the pouring chamber 2.

The installation works as follows.

Products 7, evenly hung on the conveyor 5, have passed the preliminary unit of chemical surface preparation 5 drying and cooling, along the inlet branch of the conveyor 5 enter the common chamber 1, in which the inlet platform with the steam tunnel are combined. Solvent vapor phase; The flow through the system of Jedul- ing into the common chamber 2 is condensed on the articles; 7, provide 142422

All the additional cleaning of the products 7 before painting and, consequently, an improvement in the quality of the subsequent coating, Then the products 7 are served

5 into the pouring chamber 2, where they move along an arc of a circle, in 1; the center of which is fitted with the spray gun 3, and simultaneously rotates around its own axis ,. With

In this article 7, streams of paint and varnish material are poured from nozzles 4, into which it is fed by pump 8 from tank 9, nozzles 4 on circuit 3 are circumferentially positioned so that

15 LIA 7, while moving along the loop of the conveyor 5, constantly stand against the nozzles 4, while the unproductive losses of the paintwork material are significantly reduced. Contour 3

20 is rigidly fixed to the rotator 6 of the conveyor 5, which synchronizes the rotation of the contour 3 and the movement of the products 7 on the conveyor 5, which are continuously in the streams

25 paints from nozzles 4 "Rotating in streams of paint, product 7 is evenly colored. From the chamber 2, the pouring of the product 7 is carried along the TERMINAL branch of the conveyor 5 again into the common chamber.

30 1 e g D due to the presence of the vapor phase of the solvent, a slow drain from the surface of the Delivey 7 of the paintwork material and the formation of a uniform thickness is ensured

film. Painted products 7 are supplied from the plant to the next technological operation.
