Description

Technical Field

[0001] The utility model relates to the technical field of corrugated base paper production, and more specifically, to a frozen packaging recycled corrugated base paper production device. Background Art

[0002] Corrugated paper is one of the important materials for producing corrugated board. It requires good fiber bonding strength, flat surface, good tightness and stiffness, and a certain elasticity to ensure that the finished carton has shockproof and pressure resistance. The moisture index of corrugated paper should be controlled. If the moisture is too low, the paper will be brittle and will break during corrugation processing. If the moisture is too high, the paper will be soft and it will be difficult to process and shape. Generally, the moisture content of paper should be controlled at about 10%.

[0003] The utility model patent with patent application publication number CN202221257509.0 discloses a drying equipment for corrugated paper production, including a drying equipment body. The advantage of this structure is that the drying rate is fast. By setting a humidity detector, the humidity on the corrugated paper can be detected to control the drying time of the equipment, thereby avoiding the problem of incomplete drying or over-drying of the corrugated paper. By setting an exhaust structure, when the drying is completed, the suction head extracts the water vapor generated by the drying out of the box through an exhaust pump to avoid water vapor remaining in the box. By setting a dust removal device, dust and other debris adhering to the surface of the corrugated paper can be removed in time, thereby ensuring the quality of the product and improving the processing efficiency.

[0004] However, in actual use, since the structure lacks a protective door, hot steam can easily pass through the feed inlet and the discharge port during the drying process, causing heat loss. Utility Model Content

[0009] Preferably, fans are provided on both sides of the inner cavity of the oven. The above technical solution is adopted to improve the function of evenly distributing heat in the inner cavity of the oven and improve the drying efficiency.

[0010] Technical effects and advantages of the utility model:
