AI Technical Summary

Technical Problem

Existing hot-dip galvanizing testing equipment cannot effectively detect the adhesion of the zinc layer, which may cause the zinc layer to crack or peel off, affecting the testing results.

Method used

A zinc coating adhesion testing device was designed, comprising a conveying mechanism, a limiting frame, a conveying roller, a cylinder, and a controller. The limiting frame and spring work together to prevent the test piece from shifting. The cylinder drives a stamping block to hammer the zinc coating for testing. The cylinder and connector work together to achieve orderly conveying and prevent blockage.

Benefits of technology

This improves the detection effect and conveying efficiency of zinc layer adhesion, ensuring the accuracy and reliability of the test results.
