Technical Field

[0001] The utility model relates to a spraying device, in particular to a seeding disc annular lubricating coating spraying device. Background Art

[0002] The annular spraying process of lubricating coatings involves many fields, including materials science, mechanical engineering, and automatic control. The original intention of designing this process and device is to solve the problems existing in the application process of traditional lubricating coatings, such as uneven coating, low operating efficiency, and paint waste.

[0003] In the annular spraying process of lubricating coatings, the early spraying methods often relied on manual operation, and the spraying effect was difficult to guarantee. With the development of science and technology, spraying technology has gradually achieved automation and precision. As an efficient and uniform coating application method, the annular spraying process for special-shaped parts has become a more urgent need for production enterprises to increase their production capacity.

[0004] In terms of equipment, the annular spraying device of lubricating coating usually includes spraying equipment, control system and material conveying components. The spraying equipment is responsible for spraying the coating evenly onto the surface of the object, the control system is responsible for accurately controlling the operation of the components of the spraying equipment, the opening and closing of the valves and the spraying parameters, and the material conveying components are responsible for conveying the objects to be sprayed to the spraying area. The coordinated work of these systems enables the annular spraying process of lubricating coating to be realized.

[0005] However, there are still some challenges and problems with the existing annular spraying devices for lubricating coatings. For example, the selection of coatings and the optimization of spraying parameters are crucial to the quality of the coating, but they often require a lot of experiments and adjustments based on the specific application scenarios. The tool replacement process is cumbersome, which reduces work efficiency and increases costs. In addition, problems such as paint waste and uneven coating that may occur during the spraying process also need to be solved through technological innovation. Utility Model Content
