Description
Technical Field
[0001] The utility model belongs to the technical field of color-coated plate coil spraying, in particular to a color-coated plate coil spraying device. Background Art
[0002] Color coated coil is a product made of metal coil, such as cold rolled sheet, hot dip galvanized sheet, aluminum plate, high aluminum alloy sheet and stainless steel sheet, with various organic coatings or plastic films coated or laminated on the surface.
[0003] The existing color-coated coil spraying device mainly uses high-voltage electrostatic spraying technology to achieve uniform coating coverage. The specific process is as follows: the paint is transported to the paint chamber of the sprayer through the paint delivery pipeline, and then the paint is pressurized by a high-pressure pump to form a high-pressure paint. The high-pressure paint is sprayed out through the spray gun nozzle to form a mist of paint particles, which are evenly sprinkled on the surface of the steel plate to form a coating. However, in actual use, because the color-coated coil is not pre-cleaned, there will be oil stains and other residues, which will make the coating adhesion poor during spraying and affect the service life. When using a scraper after spraying, the excess paint is not collected, resulting in the waste of uncollected paint. Secondly, the uncollected paint will also cause equipment and environmental pollution. Utility Model Content
[0004] The utility model aims to provide a color-coated plate coil material spraying device to solve the problem that the color-coated plate coil material has poor coating adhesion during spraying due to oil pollution.
[0005] The color-coated sheet coil spraying device comprises a horizontally arranged base, on which uncoilers for color-coated sheet coils are symmetrically arranged at left and right intervals, and from left to right, the first uncoiler and the second uncoiler are arranged in sequence, and from left to right, a spraying assembly, a scraper assembly and a dryer for spraying are installed in sequence on the base between the first uncoiler and the second uncoiler, and a cleaning pool is arranged on the base between the first uncoiler and the spraying assembly, and a plurality of cleaning assemblies are arranged in the cleaning pool, each cleaning assembly comprising two cleaning wheels arranged longitudinally and spaced apart from each other, and a drying fan for air-drying the color-coated sheet coil after cleaning is arranged at the right end of the cleaning pool;
[0006] The scraper assembly comprises two scrapers which are arranged horizontally and symmetrically spaced apart from each other. Both scrapers are in a "V"-shaped structure with the opening facing right. A collecting box is installed on a base below the scrapers.
[0007] The color-coated sheet coil on the first unwinder enters the cleaning tank from the left end of the cleaning tank. The cleaning tank is filled with cleaning liquid for cleaning the color-coated sheet coil. The color-coated sheet coil is preliminarily cleaned by the cleaning liquid, and the oil stains on the color-coated sheet coil are wiped off in turn through multiple groups of cleaning components to the right. Specifically, the color-coated sheet coil passes through the middle of the upper and lower cleaning wheels of each group of cleaning components to clean the oil stains on the color-coated sheet coil. The cleaned color-coated sheet coil is air-dried by the drying fan at the end of the tank, and then the paint is sprayed at the nozzle. After spraying, it passes between the upper and lower scrapers to scrape off the excess paint. After scraping, the paint on the color-coated sheet coil is dried through the drying area of the dryer, and finally reeled through the second unwinder; before spraying, the color-coated sheet coil is cleaned in the cleaning pool and then air-dried, which solves the problem of poor coating adhesion due to oil stains, etc. The "V"-shaped scraper can guide the color-coated sheet coil, making the color-coated sheet coil more stable during the rightward movement. The collection box is convenient for recycling the paint scraped off by the scraper and then centralized treatment.
[0008] Furthermore, the cleaning components are divided into two groups, one of which is located in the cleaning liquid, and the other is located above the cleaning liquid near the drying fan area.
[0009] According to the cleaning requirements, one or more cleaning components can be arranged under the cleaning liquid surface of the cleaning pool, and one or more cleaning components can be arranged above the liquid surface. The cleaning components under the cleaning liquid surface are first used to clean in the cleaning liquid, and then the cleaning liquid on the color-coated plate coil is preliminarily wiped off by the cleaning components on the cleaning liquid surface, so as to facilitate rapid air drying by the drying fan.
[0010] Furthermore, guide rollers for guiding the color-coated sheet coil are provided at the left and right ends of the cleaning tank, the left and right ends of the cleaning assembly, and the inside of the dryer.
[0011] Whether the color-coated sheet coil passes through the upper or lower side of the guide roller is determined by the direction of the color-coated sheet coil and the number of guide rollers. The guide roller facilitates the guidance of the color-coated sheet coil so that the color-coated sheet coil can be installed along the specified route.
[0012] Furthermore, the spray assembly includes two groups of nozzles arranged above the base, the two groups of nozzles are spaced apart and symmetrically arranged, a first mounting frame for mounting the nozzles is fixed on the base, and a material storage box for supplying material to the nozzles is installed on the base below the spray assembly.
[0013] By installing the upper and lower groups of nozzles on the first mounting frame, the upper and lower surfaces of the color-coated sheet coil can be sprayed at the same time. One storage box supplies two groups of nozzles at the same time, which is more efficient.
[0014] Furthermore, a feeding pipe is connected to the material storage box, one end of the feeding pipe is connected to the material storage box, and the other end is connected to the nozzle.
[0015] Furthermore, a feeding pipe for feeding the material storage box is installed on the material storage box.
[0016] The feeding pipe can be used to add materials to the material storage box to prevent the device from stopping to add materials after the paint in the material storage box is used up, thereby ensuring continuous operation of the device.
[0017] Furthermore, a second mounting frame is provided on the base on the rear side of the scraper, a first connecting block is vertically fixed to the inner top of the second mounting frame, the upper end of the scraper is fixed on the first connecting block, and the scrapers are an upper scraper and a lower scraper from top to bottom, and the front and rear ends of the upper scraper and the lower scraper are connected by a second connecting block.
[0018] The front and rear ends of the upper scraper and the lower scraper are connected by a second connecting block to increase the scraping width in the front and rear directions.
[0019] Furthermore, the scraper plate and the first connecting block, the upper scraper plate and the second connecting block, and the lower scraper plate and the second connecting block are all connected by bolts.
[0020] The bolt connection is not only stable but also removable, and easy to install and maintain.
[0021] Furthermore, a third connecting block is fixed to the top of the scraper, and the third connecting block is connected to the first connecting block through bolts.
[0022] The third connecting block is convenient for threading the bolts.
[0023] Compared with the prior art, the utility model has the following beneficial effects:
[0024] Before spraying, the color-coated coil is cleaned in a cleaning tank and then air-dried, which solves the problem of poor coating adhesion caused by oil stains, etc. The "V"-shaped scraper can guide the color-coated coil, making it more stable during the rightward movement. The collection box is convenient for recycling the paint scraped off by the scraper and centralized treatment. BRIEF DESCRIPTION OF THE DRAWINGS
