Corrugated board processing glue drying device

The utility model discloses a corrugated board processing glue drying device, which belongs to the field of drying devices and comprises a corrugated board conveying belt and a drying mechanism arranged on the corrugated board conveying belt. After being electrified and heated, the air heater blows air downwards through the draught fan, hot air is blown down to the corrugated board conveying belt from a gap formed in front of the air guide plate, and therefore glue coated on corrugated boards on the corrugated board conveying belt is evenly dried, meanwhile, the hot air penetrates through the gap of the corrugated board conveying belt to enter the air return cover, and the glue on the corrugated boards is evenly dried. And the hot air enters the heating box again through the air return pipe, so that the purpose of cyclic utilization of the hot air is achieved, heat is prevented from overflowing outwards, energy consumption needed during drying is reduced, meanwhile, in the hot air circulation process, a pecul
