Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a double-sided synchronous drying equipment for corrugated cardboard with uniform heating. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet", "corrugated paper", "corrugated core", "corrugated base paper") and one layer of cardboard (also known as "boxboard"). It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and the cardboard, and the structure of the carton itself.

[0003] Current methods for processing corrugated cardboard require drying, but typically only one side of the cardboard is heated during drying. This can lead to uneven heating, and due to the principle of thermal expansion and contraction, the cardboard may expand during heating, potentially causing deformation and delamination. This necessitates rework, increasing labor intensity and reducing processing efficiency.

[0004] Therefore, it is necessary to invent a double-sided synchronous drying equipment for corrugated cardboard with uniform heating. Summary of the Invention
