Device for cleaning the transparent endless belt for rapid UV polymerization of the paint that covers products with a mainly flat surface

摘要

Apparatus for cleaning the descending branch (102) of an endless transparent tape (2) for rapid UV catalysis of the paint covering panels (P) of wood or other material or other products with a flat surface, characterized by the sequence, from top to bottom, at least the following means: - a first upper recoil roller (10) that involves the descending transparent tape (102) for the complete transverse extension of this and a first bar (13) to dispense at the entrance upper formed by this recoil roller and the transparent tape (102) an amount of solvent useful to dilute the paint to be removed, this first recoil roller (10) has characteristics such as distributing the solvent evenly over the tape (102) and perform on this a first rubbing action also useful to separate the paint, spread it and make it easier and more quickly reactive to the solvent and distribute this diluted paint on a mplia extension of the transparent tape (102); - at least one first cleaning blade (19) that involves the transparent tape (102) for the entire transverse extension of the latter and that forms an obtuse angle with the upper section of this transparent tape, all so that with the combined action of the scraping and gravity this cleaning blade (19) collects and removes all solvent and diluted paint from said first upper recoil roller (10); - a second upper recoil roller (10 ') that involves the transparent tape (102) for the entire transverse extension thereof, to subject it to a substantial cleaning action; - wherein at least said second upper recoil roller (10 ') or both mentioned retraction rollers (10, 10') are formed by cylindrical metal rollers covered with several windings of a fabric, for example, a felt fabric (26 ). - a bar (13 ') combined with the second recoil roller (10') to dispense more solvent in the upper inlet formed by this recoil roller (10 ') and by the transparent tape (102), all to make a second mechanical operation of rubbing and cleaning the transparent tape and diluting any residual fluid paint, providing after these means, - at least a second cleaning blade (19 ') that touches the tape (102) for the entire transverse extension of this and which forms an obtuse angle with the upper section of this transparent tape (102), to collect and remove all the solvent and any trace of very easily diluted paint and then perform a drying operation of this transparent tape (102).
