AI Technical Summary

Technical Problem

After the roller conveyor stops conveying the steel plate at the designated position, it continues to rotate due to inertia, causing friction and wear between the roller and the steel plate, which reduces the processing and cutting accuracy and the roller life.

Method used

A high-precision automatic feeding and cutting device was designed. The contact switch detects the contact between the steel plate and the limit plate. The controller cuts off the power to the conveyor roller and lifts the steel plate through the lifting mechanism to avoid the steel plate from contacting the inertial rotating conveyor roller. Combined with the inclined rubber rod, the steel plate is guided to fall and the impact of the steel plate is buffered.

Benefits of technology

This effectively avoids inertial wear between the steel plate and the conveyor roller, improves cutting accuracy and roller lifespan, reduces steel plate damage, and improves production efficiency and product quality.
