AI Technical Summary
Existing paper humidity control devices are unable to achieve stable moisture retention on the bottom surface of the paper, leading to problems such as paper deformation, brittleness, and mold growth.
A paper humidity retention device was designed. By setting up a water-absorbing sponge and a lifting mechanism in the humidity retention box, water is introduced into the water storage chamber by the pump and enters the water-absorbing sponge through the through hole to achieve the wetting of the water-absorbing sponge. The lifting mechanism makes the water-absorbing sponge cover the paper surface to achieve all-round moisture retention.
It achieves all-round moisture retention of paper, avoids the problem of the bottom of the paper not being moisturized, and improves the paper's moisture retention effect.
