Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate coloring equipment, in particular to a high-efficiency aluminum plate coloring device. Background Art

[0002] Aluminum sheet is a flat product made of aluminum material. It is usually made of aluminum alloy or pure aluminum material. It has the characteristics of light weight, corrosion resistance, good thermal conductivity, etc. In order to improve the performance and aesthetics of aluminum sheet, it is sometimes necessary to color the surface of aluminum sheet. The existing coloring methods mainly include anodizing: Anodizing is a common coloring method for aluminum sheet. The process involves immersing the aluminum sheet in a tank containing an acid electrolyte and forming an oxide film on the aluminum surface under the action of electric current. The oxide film can be colored by dyes to give the aluminum sheet a rich color and surface effect. Anodizing not only provides color selection, but also increases the hardness and corrosion resistance of the aluminum sheet; Spraying: Spraying is a common coloring method for aluminum sheet. The surface of the aluminum sheet can be colored by spraying paint. Spraying can provide a wide range of color options and can achieve various surface effects such as smoothness, texture or metallic texture. The coating can be an organic coating, such as polyester coating (PE), polyvinyl fluoride coating (PVDF), etc., or an inorganic coating, such as powder coating; Electrophoretic coating: Electrophoretic coating is a coloring method in which the paint is electrophoresed onto the surface of the aluminum sheet. The aluminum plate acts as a cathode and is immersed in an electrolytic cell containing charged paint particles, which form a uniform coating on the surface of the aluminum plate. Electrophoretic coating provides good adhesion and durability, and can achieve a variety of colors; Printing: Aluminum plates can be colored by printing technology. Printing can be done by different methods, such as screen printing, inkjet printing, etc. Through printing, patterns, text or complex images can be created on the surface of the aluminum plate, and a variety of color effects can be achieved. Among them, spraying is a more common way to color aluminum plates.

[0003] However, the existing method of spraying coloring of aluminum plates has the following problems: the equipment used for spraying coloring of aluminum plates usually uses a nozzle to spray color on the surface of the aluminum plate, but because the pigment sprayed by the nozzle is usually radial, this easily leads to the color depth and thickness of the middle area of ​​the nozzle being usually greater than the color depth and thickness of the edge area of ​​the nozzle, resulting in color difference on the surface of the aluminum plate, and in order to achieve a better spraying effect on the aluminum plate, the aluminum plate is usually sent into the spraying equipment in a suspended manner, and the impact of the sprayed pigment may cause the aluminum plate to shake, and there is a possibility of spraying error, and the vertical spraying method easily leads to some pigment residues concentrated on the bottom of the aluminum plate, affecting the appearance. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Summary of the invention
