Description

Technical Field

[0001] The utility model relates to the technical field of roller production, in particular to a spraying device used for roller production. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metals. Rollers are mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the press-down device. The varieties and manufacturing processes of rolls are constantly developing with the advancement of metallurgical technology and the evolution of steel rolling equipment.

[0003] In order to improve the surface quality of the roller, it is often necessary to spray strengthening materials on the surface of the roller during production. At present, most of the methods are artificial open-air spraying, which is not only inefficient, but also the scattered paint will pollute the environment and affect the health of workers. In addition, some mist paint will escape into the air. When too much mist paint escapes, it will not only affect the air quality of the working environment but also cause a large degree of waste.

[0004] For this purpose, we propose a spraying device for roller production. Utility Model Content
