Description

Technical Field

[0001] This utility model relates to the field of paperboard processing technology, and in particular to a drying device for curing adhesives on corrugated paperboard. Background Technology

[0002] In the production process of corrugated cardboard, the use of glue plays a key role in firmly bonding the different layers of base paper together. The quality of glue curing directly affects the overall strength, flatness, and moisture resistance of the corrugated cardboard. Among these factors, the drying process, as an important step in achieving effective glue curing, is becoming increasingly important.

[0003] In existing processing, corrugated cardboard is often dried with a dryer to remove the glue. However, during the operation of the dryer, due to the long conveyor belt of the corrugated cardboard and the tendency of heat to escape during drying, not only does the dryer consume a lot of energy, but it also results in uneven drying of the corrugated cardboard. In addition, the glue applied to the corrugated cardboard will produce an odor after drying, and existing dryers cannot effectively deal with the odor.

[0004] An existing patent (publication number: CN218190811U) discloses a corrugated cardboard adhesive drying device, belonging to the field of drying devices. It includes a corrugated cardboard conveyor belt. A drying mechanism is installed on the conveyor belt. An air heater, after being energized, blows hot air downwards through a fan, creating a gap in front of the air guide plate onto the conveyor belt. This evenly dries the adhesive coated on the corrugated cardboard. Simultaneously, the hot air passes through the gap in the conveyor belt into a return air hood and then re-enters the heating chamber through a return air duct. This achieves hot air circulation, prevents heat loss, and reduces energy consumption during drying. Furthermore, during the hot air circulation, an odor removal mechanism in the return air hood removes odors generated during the drying process using an activated carbon filter, preventing these odors from affecting the health of workers.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing tunnel drying devices lack a structure for multiple heating and drying of corrugated cardboard in different zones, resulting in uneven heating of different areas of the corrugated cardboard during a single heating process, which affects the final bonding strength and overall strength of the cardboard.

[0006] Therefore, a drying device for curing adhesives on corrugated cardboard is proposed. Utility Model Content
