Coating device

Abstract

The invention provides a coating device which comprises a support base body and a coating assembly. The support base body is provided with a holding space; the coating assembly is nested with the support base body, and comprises a coating part, a flexible coating body and a connecting part; the coating part is connected with the connecting part and is rotatably arranged in the holding space through the connecting part; the flexible coating body is arranged on the surface, deviate from the support base body, of the coating part and can dip-dye a liquid material; the coating assembly can drive the flexible coating body to rotate through the coating part so as to form a coating space in an enclosing way; and the flexible coating body rotates around a part to be coated in the coating space, sothat the surface of the part to be coated is coated. The coating device provided by the invention is used for replacing manpower for coating the part to be coated, so that at least one of the aims ofimproving the coating efficiency, reducing the cost and avoiding bringing harm to the personal safety of operating personnel is achieved.

Description

technical field [0001] The invention relates to the technical field of auxiliary spraying equipment, in particular to a coating device. Background technique [0002] As one of the most commonly used connection methods, bolt connection is widely used in various industries such as aerospace, bridge construction, shipbuilding, and wind power generation. The effective connection of bolts is one of the important conditions to ensure the normal operation of the equipment. However, due to the many edges and corners of the bolts, the uneven surface, and the side gap at the connection, it is easy to store corrosive media such as water, salt, and moisture, which may cause Bolts are rusted, corroded, or even broken, which will affect the operation of the equipment and cause economic losses and potential safety hazards. Especially in the field of wind power generation technology, when the wind turbine is in a humid or salty environment such as the sea, effective anti-corrosion treatmen...

Problems solved by technology

[0004] However, when the bolts are anti-corrosion treated by manually painting cold-sprayed zinc, it is easy to cause phenomena such as uneven thickness of the bolts, incomplete surface painting, and irregular painting areas, which will reduce the anti-corrosion effect and affect the appearance of the product.

In addition, the method of artificial brushing is usually volatile and highly toxic, and long-term contact with anti-corrosion coatings will have a certain impact on health, so it will endanger personal health and require a large labor cost.
