AI Technical Summary

Technical Problem

After prolonged use, the pressure rollers of existing compression and shear testing machines tend to accumulate impurities, resulting in uneven surfaces and affecting test results.

Method used

A self-cleaning protective device for a dynamic compression shear testing machine was designed, including a blower mechanism and a cleaning and polishing layer. Through the cooperation of a hydraulic telescopic rod and a rotating shaft, a U-shaped wrapping pressure roller is formed. The cleaning and polishing layer is used to clean impurities, and the blower removes residual impurities.

Benefits of technology

Effective cleaning of impurities on the surface of the pressure rollers avoids uneven surfaces and ensures the accuracy of test results.
