AI Technical Summary

Technical Problem

When pressure is applied to the four corners of the enamel corrugated sheet, the central area does not receive effective support, leading to leakage and cross-contamination problems.

Method used

The structure employs bearing assemblies and threaded rods. Connecting rods and nuts are installed at the four corners of the pressure plate, and a support seat and a central support plate are installed in the central area of ​​the pressure plate. The threaded rods support the central area, preventing deformation caused by applying pressure only at the four corners.

Benefits of technology

It effectively prevents deformation in the central area of ​​the enamel corrugated sheet, avoids leakage, and improves the stability and sealing of the enamel corrugated sheet.
