A high adsorption and penetration type coating device for steel strip processing

Abstract

The invention discloses a high-absorbing and permeable coating device for steel strip processing, which belongs to the technical field of metal material coating. By setting a plurality of sets of magnetic liquid-absorbing capsules in the coating roller, the pair of electromagnetic sheets rotates to the immersion chamber. A plurality of magnetic liquid-absorbing sacs are adsorbed and stretched, and the magnetic-absorbed liquid-absorbed sac and the outer permeable layer elastically expand downwards to expand its adsorption pores and improve the adsorption of the coating solution, which is conducive to continuously fully coating the coating solution on the steel. On the belt, the coating effect is enhanced, and at the same time, the metal powder is sprayed on the steel belt under high pressure. The metal powder covers between the paint surface and the coating layer, which not only helps to improve the metal texture of the coating layer, but also improves the paint surface. It plays a protective role. In addition, the metal powder forms tiny holes on the paint surface, which is conducive to the penetration of the coating solution into the tiny holes, improving the coating effect between the coating layer and the paint surface, and effectively preventing the coating layer from stripping.

Description

technical field [0001] The invention relates to the technical field of metal material plating, and more specifically relates to a high adsorption and penetration type coating device for steel strip processing. Background technique [0002] Steel belt refers to the conveyor belt made of carbon steel as the traction and carrying member of the belt conveyor, and can also be used to bundle goods. It is a kind of steel belt that various steel rolling enterprises need to meet the industrial production of various metal or mechanical products in different industrial sectors. A narrow and long steel plate produced, after the steel strip is produced, it needs to be coated with a layer of paint on its end surface, so as to be suitable for different processing needs. [0003] In the prior art, paint is often applied to the surface of the metal steel strip by means of a coating roller brush to form a paint surface. By spraying liquid paint on the surface of the rotating roller and contac...

Problems solved by technology

In the existing simple coating method, if the feeding material is insufficient, it is easy to cause poor uniformity of the paint surface, not only the adhesive force is too small, but also the failure and peeling of the paint under the action of air, water, and alternating stress often occur. Occurs, seriously affecting the quality and service life of the steel belt
