Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of corrugated cardboard box processing equipment, specifically a circulating drying device for corrugated cardboard box printing. Background Technology
[0002] When corrugated boxes are processed, the corrugated boxes to be dried enter the drying device through the conveying system. The heating element generates heat, and the circulating fan causes the hot air to circulate in the air duct, blowing evenly on the surface of the box, so that the solvent in the ink evaporates quickly and the drying is achieved.
[0003] Existing circulating drying equipment for corrugated carton printing still has the following problems during use: Despite the air duct design, the drying area may still have uneven temperature in actual operation, that is, the temperature is higher near the heating element or the air duct outlet, while the temperature is lower in areas away from these parts. This will cause the ink drying speed to be inconsistent in different parts of the carton, affecting the printing quality. In addition, although the circulating system can recover some hot air, there may still be a problem of large heat loss, especially during long-term operation, the energy consumption is still high, and the production cost is increased.
