Description

Technical Field

[0001] The invention belongs to the technical field of corrugated cardboard pressing, and in particular relates to a corrugated cardboard pressing device with a high-efficiency drying mechanism. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] During the production process of corrugated cardboard, adhesive (usually a mixture of starch and water) needs to be applied to both sides of the corrugated paper, and then a laminating device is used to extrude and laminate the multiple layers of cardboard to form a corrugated cardboard. However, since the adhesive contains a certain amount of moisture, and conventional laminating equipment does not have the function of drying the corrugated cardboard after lamination, the moisture will cause the pressed corrugated cardboard to be prone to wrinkles and damage in subsequent processes, affecting the production quality of the corrugated cardboard.

[0004] Combining the above-mentioned problems, it is found that it is difficult to avoid the above-mentioned problems when the existing laminating equipment on the market is in use, and thus it is impossible to achieve the desired effect. Therefore, we propose a corrugated cardboard laminating equipment with an efficient drying mechanism, which can achieve the effect of efficiently, evenly and accurately drying the pressed corrugated cardboard during use, greatly improving the laminating quality and production efficiency of the corrugated cardboard.
