Abstract: A paint recovery and cleaning trolley is provided for an apparatus for applying paint provided with a belt for conveying pieces to be painted.
The conveyor belt has an upper outward section and a lower return section. The trolley includes a paint recovery subunit and a cleaning subunit. Each subunit includes a reverse roller in contact with the lower return section of the conveyor belt, a doctor blade tangentially placed with respect to the reverse roller for all its length, and a doctor blade scraping the lower return section of the conveyor belt. In each subunit the respective reverse roller, doctor blades and return section of the conveyor belt form a closed chamber having the shape of a triangular prism, of which the components represent the rectangular faces and that contains a solvent which drips from the triangular faces into a respective collecting hopper. Three positions of the trolley are provided including two inserted positions in which the trolley is totally inserted under the conveyor belt and may be inactive or in operation and a lateral extracted position in which the trolley is totally extracted from the apparatus for applying paint.
