AI Technical Summary

Technical Problem

The existing chrome plating working tank submerged rollers are difficult to seal easily during use, which may cause plating liquid to enter the interior and cause corrosion and other problems.

Method used

A high-speed continuous chromium plating working tank submerged roller device was designed, including a sealing structure and a reinforcing structure. The sealing structure abuts against the bushing through a sealing ring and uses a limit spring to push the push block to prevent plating solution from entering. The reinforcing structure protects the submerged roller body through an anti-corrosion layer and a wear-resistant layer.

Benefits of technology

This design achieves effective sealing of the submerged roller, preventing plating solution contamination and enhancing its corrosion resistance and wear resistance, thereby improving the practicality and service life of the device.
