Description

Technical Field

[0001] The utility model relates to the technical field of steel strip processing, in particular to a double-sided coating device for steel strips. Background Art

[0002] Stainless steel strip is simply an extension of ultra-thin stainless steel plate. It is a narrow and long steel plate produced to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. After rolling, in order to protect the surface of stainless steel strip, it is necessary to coat the surface of stainless steel strip with protective paint, and electrostatic spraying is one of the many coating methods for stainless steel strip.

[0003] At present, when protective paint is applied to both sides of stainless steel strips by electrostatic coating, the coating operation is mainly carried out in an open place by manually holding an electrostatic spray gun. Although the coating process on both sides of the stainless steel strip can be achieved in the above coating method, the coating process requires manual continuous holding of the electrostatic spray gun, which greatly increases the labor intensity of the manual labor and cannot meet the large-scale coating processing needs of the steel strips. In addition, in the above spraying method, since the entire spraying space is an open structure, the dust generated during the spraying process is easy to splash everywhere, making the environment of the steel strip coating site relatively dirty.
