摘要

Paint recovery and cleaning trolley (3, 33) for an apparatus (1) for applying paint provided with a belt (2) for conveying pieces to be painted, comprising:- A paint recovery subunit (21), in its turn comprising:▪ A reverse roller (19) in contact with the lower return section of said conveying belt (2), which recovers paint from the belt,▪ A doctor blade (11) tangentially placed with respect to said reverse roller (19) for all its length, to allow the accumulation of a solvent and wetting said reverse roller (19);▪ A doctor blade (14) scraping the reverse roller (19) so recovering paint;▪ A doctor blade (10) scraping the lower return section of said conveying belt (2),▪ At least one nozzle (13) for supplying a solvent compatible with the paint in use,▪ A hopper (12) collecting said solvent, placed under said reverse roller (19),▪ A paint collecting reservoir (130),- A cleaning subunit (22), in its turn comprising:▪ A reverse roller (29) in contact with the lower return section of the conveying belt (2),▪ A doctor blade (211) tangentially placed with respect to said reverse roller (29) for all its length to allow the accumulation of a solvent and wetting said reverse roller (29),▪ A doctor blade (210) scraping the lower return section of said conveying belt (2),▪ At least a nozzle (213) for supplying a solvent,▪ A hopper (212) collecting said solvent, placed under said reverse roller (29),▪ A solvent collecting reservoir (231),wherein in each subunit (21, 22) said components (19, 11, 10, 2; 29, 211, 210, 2) form a closed chamber having the shape of a triangular prism, of which said components (19, 11, 10, 2; 29, 211, 210, 2) represent the rectangular faces, said chamber containing said solvent, which slowly drips from the triangular faces of said chamber into a respective collecting hopper (12, 212).
