(54) INSTALLATION FOR COATING

I

The invention relates to equipment for painting products and can be used in the mechanization of paint production lines, mainly in installations for applying paint coatings by dipping and spray painting.

According to the main author. St. For 722591, there is a known device for coating products, comprising an inlet and an exit vestibule, a flooring device, a transporting device, a steam tunnel and a means for covering the coating material installed in it, made in the form of a driving endlessly closed horizontal tape provided with a scraper, installed between the coater and the steam tunnel, with the upper branch of the tape being made in the form of a groove 11.

This chamber is characterized by the impossibility of using a conveyor of the same width during the coating of various products.

The aim of the invention is the expansion of technological capabilities.

The goal is achieved by the fact that OOCH in the installation for the coating of IPA PRODUCTS

items containing inlet and outlet vestibules, a device for coating, a transporting device, a steam tunnel and installed therein means for the flow of the coating material, made in the form of a drive endlessly closed horizontal tape, provided with a scraper installed between the device for coating and a steam tunnel, with In this case, the upper branch of the tape is made in the form of a gutter, the means for the drainage of the coating material are provided with inclined scaffolds installed along the upper branch of the tape on both sides, SETTING provided with a collector for the solvent with the openings disposed beneath the belt to the scraper movement direction by the top

15 branches of the tape.

FIG. 1 shows schematically the installation, the general view; on fng. 2 - section aa and pa of fig. one; in fig. 3 shows the node I in FIG. 1. The coating installation has an inlet trough 1 and an exit 2,

Claims (2)

30 a device for applying coating (painting) 3, a steam tunnel 4. At the bottom 5 and 6, respectively, of the steam tunnel 4 and the exit vestibule 2, a belt conveyor 7 is installed. Connect the device to paint 3 with tray 8. One end of the tray is located nl the cone-shaped bottom 9 of the device for the border 3, and the second is pressed against the belt 10 of the conveyor 7. The belt 10 is made of a solvent-resistant material, for example rubber, leaf oil-resistant or other materials. The pressed part of the tray 8 is provided with multi-elastic scraper II, made, for example, of a conveyor belt. The pressing is carried out due to the asymmetrical positioning of the tray 8 relative to the axis 12, which is fixed in the supports at the bottom 5 of the steam tunnel 4. To adjust the pressing force, the tray is equipped with a screw 13. For better cleaning of the tape 10, it is covered with a film 14 with poor adhesion to paints and varnishes, for example, polyvinyl chloride material. For washing the belt 10 with a solvent, a collector 15 is installed between it and the pressed end of the tray. The collector 15 is provided with holes 16 with a length equal to the width of the conveyor belt 7. To reduce the width of the belt 10 of the conveyor 7, the latter is equipped with removable flaps 17 installed on both sides along its entire length an angle of 15-20 ° above the tape 10 and the width of the painted product. The supporting rollers 18 form a grooved tape form 10 in which paints and varnishes can accumulate. In addition, elastic edges 19 are installed along the edges of the tape 10. The installation operates as follows. The products on the overhead conveyor enter the inlet of the I, the device for painting 3, where paints and varnishes are applied, then steam treatment is carried out in the tunnel 4 and through the platform 2 goes to the next process step. The painted products in the steam tunnel Le 4 and partially in the exit vestibule 2 are continuously drained with an excess of paints and varnishes that fall into the groove of the upper branch of the belt 10 of the conveyor 7 installed on the bottom 5 and 6 and moves in the direction of the coloring device 3. The flanges 19 additionally prevent the spreading of paints and varnishes from the tape 10. Scrapers 11 of the tray 8, whose pressing force is adjusted by screws 13, continuously clean the belt 10 of the conveyor 7, covered with film 14, from paintwork material a, which enters the cone-shaped bottom of section 9 along the chute 8, staining 3. When the scrapers II are worn out, the screws 13 and the chute 8 turn out, turning around the axis 12 again presses the scrapers II to the belt 10. Excess paint and varnish materials falling onto the flaps 17, due to large drain angle, immediately goes to tape 10. The use of this installation allows you to expand its technological capabilities. Claims. Installation for coating products by author. St. No. 722591, characterized in that, in order to broaden the technological possibilities, the means for draining the coating material are provided with inclined guards installed along the upper branch of the tape on both sides. 2. Installation according to claim I, characterized in that it is provided with a solvent collector with openings located under the belt in front of the scraper in the direction of movement of the upper belt branch.
