Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of waste metal plate rust removal facility design, especially relates to a waste metal plate recycling polishing rust removal device. BACKGROUND

[0002] Rust will make the metal plate surface become rough and uneven. In some occasions where the surface flatness is required to be higher, such as making metal handicrafts or the shell of precision instruments, polishing rust can make the metal plate surface smooth, which is beneficial to subsequent processing operations, such as paint spraying, electroplating, etc. Smooth surface can make paint spraying more uniform, improve the adhesion of the coating, thereby enhancing the corrosion resistance of the metal plate; better electroplating effect can be obtained during electroplating, improving the appearance and service life of the metal plate.

[0003] If the waste metal plate is discarded due to rust, a large amount of metal resources will be wasted. By polishing rust, the waste metal plate can be reused, reducing the exploitation of new metal resources. For example, in the automobile manufacturing industry, the metal parts of the waste automobile can be remanufactured after polishing rust, which helps to save metal resources such as iron and aluminum, and reduces the dependence on natural resources.

[0004] The existing metal plate polishing device can only polish one side of the metal plate at a time, and it is difficult to quickly polish both sides of the metal plate, and the processing time is long. At the same time, only metal plates with fixed thickness can be processed, and the processing range is small. UTILITY MODEL CONTENT
