AI Technical Summary
Existing pulp molding lacks a compression-resistant structure, making it easily crushed or deformed, resulting in insufficient performance in packaging applications.
In pulp molding, a buffer assembly and a support assembly are set up. The buffer assembly is driven by a compression spring to extend a rubber plate for initial cushioning, while columns and iron rods provide support to enhance compressive strength.
The synergistic effect of the buffer and support components significantly improves the compressive strength of the pulp molding, preventing deformation and breakage.
