Description

Leveling and curing device for water-based paint and water-based UV paint Technical Field The invention belongs to the technical field of curing devices, and particularly relates to a leveling and curing device for water-based paint and water-based UV paint. Background The water-based paint and the water-based UV paint are increasingly widely applied in the field of surface coating due to the remarkable advantages of environmental protection and low volatility. However, water-based paint and water-based UV paint are widely used in the coating field due to their environmental protection characteristics, but their drying and curing processes put higher demands on equipment. The existing coating production line is generally composed of three core links of spraying, leveling and drying and UV curing, and the technical configuration of each link directly influences the final coating quality and the production efficiency. In the spraying step, the existing reciprocating spraying device mostly adopts a semi-open structure, and a large amount of paint mist generated in the spraying process is seriously dissipated, so that the consumption of water paint raw materials is increased. Although some equipment is provided with a simple air draft device, there is still room for improvement in the aspects of paint mist recovery and drip collection, and the recycling efficiency of paint is required to be improved. In the leveling and drying step, the drying characteristics of the water-based paint require that the moisture in the coating layer fully escapes before film formation. In the existing technology of infrared light wave irradiation, part of schemes simply arrange infrared light sources in a box body, although the infrared light sources can heat the surface of a workpiece, the radiation uniformity is greatly influenced by the arrangement mode of the light sources, and the surface of a complex workpiece is difficult to be heated uniformly. In the UV curing link, different types of light sources have different curing characteristics, and the curing quality and the workpiece qualification rate of the water-based UV paint are directly determined by the performance suitability, the temperature control effect and the structure linkage. In the traditional double-lamp UV curing device, the double lamps are mainly composed of common UV mercury lamps and halogen lamps, a high-efficiency closed-loop water cooling circulation system is not configured between the common UV mercury lamps and the halogen lamps, a large amount of infrared radiation heat is generated in the working process, the internal temperature of equipment is rapidly increased, the surface temperature of a workpiece is increased, the workpiece is deformed and a paint layer is emitted Huang Laohua, the self temperature of a light source is increased, the service life of the light source is greatly shortened, the maintenance cost of the equipment is increased, meanwhile, the distance between the light sources is mainly fixed, the defects that the ultraviolet mercury lamps are unstable in radiation intensity, uneven surface layer curing, incomplete deep layer curing and the like are caused due to the fact that the temperature change of a shell caused by power fluctuation and lamp tube aging cannot be adapted to. In addition, the existing temperature control mostly adopts traditional electronic PID control, has the problems of response delay, overshoot oscillation and the like, is difficult to accurately match with transient thermal change in the curing process of the water-based UV paint, has insufficient cooling efficiency and accuracy, lacks cooperative linkage with a mechanical structure, and has poor thermal management effect. Disclosure of Invention The invention provides a leveling and curing device for water paint and water-based UV paint, which aims at solving the problems of paint waste in a spraying link, uneven heating in a leveling and drying link, insufficient temperature control in a UV curing link and poor cooperativity of each link in the existing coating production line. In order to achieve the functions, the technical scheme adopted by the invention is that the leveling and curing device for the water paint and the water UV paint comprises a reciprocating spraying box internally provided with symmetrical reciprocating spraying components, a plurality of groups of leveling and curing boxes and double-lamp UV curing boxes which are communicated, wherein a first transmission component for conveying workpieces to be sprayed is horizontally arranged in the reciprocating spraying box; the leveling curing boxes are sequentially communicated in series along the conveying direction of the workpiece, second conveying assemblies which are flush with the horizontal plane of the first conveying assembly are arranged in each leveling curing box, and the second conveying assemblies and the first conveying assemblies are synchronously linked; the top of the level
