Description

Technical Field

[0001] The invention relates to the technical field of stainless steel production, in particular to a painting device used for the surface of stainless steel. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has stainless properties is called stainless steel, while steel that is resistant to corrosion by chemically corrosive media (acids, alkalis, salts, etc.) is called acid-resistant steel.

[0003] In order to further increase the rust resistance of stainless steel, its surface needs to be painted. The traditional way is for workers to spray it manually, but this is not only time-consuming and labor-intensive, but also leads to uneven spraying. Now, automated mechanical painting equipment is generally used. The working principle is that the stainless steel parts are transported forward on the conveyor belt, and the nozzle above them moves back and forth quickly to spray paint on them.

[0004] However, the current painting equipment lacks a mechanism for preliminary drying immediately after painting. If the paint cannot be dried in time, the final anti-rust performance of the stainless steel will be affected. In addition, when the stainless steel is transported on the conveyor belt, dust and other particles in the air will fall on its surface, and the current painting equipment lacks an effective dust removal mechanism, which will result in unsatisfactory adhesion between the paint and the stainless steel surface, thereby affecting the final anti-rust performance. In view of this, we propose a painting equipment for stainless steel surfaces. Summary of the invention

[0020] 1. The painting equipment for stainless steel surface is provided with a rotating mechanism in order to better preliminarily dry the stainless steel body after painting to improve the anti-rust performance. When the transmission roller rotates, the long tube rotates between the inner walls of the frame in cooperation with the left transmission belt and the horizontal transmission belt, so that the stainless steel body below can be scraped and dried by the airflow in cooperation with the sleeve, the arc block and the rectangular plate.

At the same time, the arc block, rectangular plate and fan blades in the rotating mechanism are coordinated to make the hot air flow better blow to the top of the stainless steel body, so as to achieve the best drying effect, thereby further improving the effect of paint adhesion and further improving the anti-rust performance.

[0022] 3. In order to further protect the internal cavity of the arc surface block from dust, the painting equipment for the stainless steel surface is provided with an auxiliary component. When the arc surface block rotates, the centrifugal force is used to make the arc surface slider slide inside it in the direction away from the sleeve, thereby compressing and deforming the reset spring.
