AI Technical Summary
The existing drying process after coating corrugated base paper results in poor moisture content control, which can easily lead to paper tape breakage. Furthermore, the increased ambient temperature after prolonged operation of the drying equipment affects the moisture loss of the paper tape.
The system employs an inner expansion hood and an outer contraction hood in conjunction with negative pressure extraction. By using negative pressure extraction and gas compression at the inlet and outlet, the suction force is increased to accelerate film evaporation and rapidly cool the paper tape, thus preventing moisture loss.
Effectively controlling the moisture content of corrugated base paper reduces the risk of breakage, improves production efficiency, and enhances the practicality of the equipment.

TECHNICAL FIELD
[0001] The utility model relates to corrugated paper processing technical field, in particular to a surface treatment device of corrugated paper. BACKGROUND
[0002] Corrugated paper is one of important component materials of producing corrugated paperboard, is the raw paper used to constitute corrugated paperboard wave shape core. It is corrugated by the corrugated roller heated to 160~180 DEG C from the core paper, and the corrugated paper is formed. Corrugated paper requires good fiber bonding strength, paper surface is even, has better tightness and stiffness, requires certain elasticity to ensure that the paper box has shockproof and pressure resistance.
[0003] In the production process of corrugated paper, the surface of the raw paper needs to be glued and coated to improve the surface performance of the corrugated paper and improve the physical properties of the paper sheet. In the existing corrugated paper coating process, after the corrugated paper is coated, in order to ensure that the film is quickly dried and facilitate subsequent direct winding and packaging, a drying process is added. However, due to the particularity of corrugated paper, too little water content will cause the corrugated paper to be brittle and increase the probability of corrugated processing rupture, so the water content of the corrugated paper needs to be controlled at about 10%. Although the heating section is short due to the thinness of the film in the existing drying process design, the ambient temperature near the equipment will also rise after long-term operation, resulting in the actual heating time being longer than the time through the heating section. In the subsequent cooling process, the corrugated paper will lose more water, which is not conducive to the subsequent water content control and has further improvement space. UTILITY MODEL CONTENTS
