Apparatus for painting mainly flat products including a spray booth, in its turn including a plenum, a conveying belt for conveying products at least a device for applying paint, and at least one suction plant, wherein the plenum of the spray booth has a symmetric M-shape including, from the respective peripheries to the centre of the plenum:

Apparatus for applying paint to mainly flat parts

Spray booth () for applying paint on basically flat parts (), said spray booth having a plenum () and comprising a conveying system () for conveying the flat parts () to be painted, at least a device () for applying paint on said moving parts, and at least a suction system, wherein the plenum () of the spray booth has a semi-cylindrical shape, having its axis perpendicular to the direction of the advancing part ().

Method and apparatus for applying paint on basically flat parts

A paint spraying machine includes an apparatus for containing and removing the leakage of paint drops from a rotating joint, without the risk of damaging the article being sprayed, and thus without the need for downtime to replace sealing elements. The rotating joint includes a hollow shaft for distributing paint, a drum including a plurality of flanges that define separate chambers for different paints, a plurality of seals for separating the different paints in the different chambers which together form a high-pressure circuit, a low-pressure circuit to refrigerate the seals, improve their sealing and possibly intercept leaking paint, and a plurality of centering rings provide for correct assembly of the seals and the correct alignment of different flanges. The rings are hollow, and allow for the passage of the refrigerating/cleaning liquid under low pressure. A method for operating the machine includes containing and removing the leakage of paint drops from a rotating joint and distributing them back to the supplying tank of the refrigerating/cleaning liquid.

A device for cleaning a conveyor belt soiled with fluid substances, and in particular for machines used for spraying paint or other products, is disclosed. The conveyor belt has an upper section and a lower return section comprising a (a) reverse roller in contact with the return section of the belt to collect the fluid substances on the belt; (b) doctor blade for scraping the fluid substances collected from the reverse roller; (c) at least one secondary belt conveyor mounted on a pair of supporting rollers and disposed beneath the doctor blade for collecting the fluid substances from the doctor blade and for conveying the fluid substances toward one end of said secondary belt conveyor; and (d) means at the end of the secondary belt conveyor for scraping the fluid substances from the secondary belt conveyor and for conveying the substances to a final collection and/or recycling means.
