At present, conventional ovens are composed of multiple air nozzles evenly distributed up and down. These air nozzles have two double-sided air ducts or air outlets, and the two air ducts or air outlets are set opposite to each other, so as to guide the hot air to the surface of the material substrate. However, the double-sided air nozzles will affect the flow rate of the hot air in the oven, resulting in the drying efficiency being affected. Utility Model Content

[0012] The utility model has the following advantages:

[0013] 1. The utility model provides a same-direction air nozzle structure, which forms a same-direction double-air duct structure by setting a first air duct and a second air duct in the same direction. During drying, the hot air is guided in the same air outlet direction, so that the flow direction of the hot air is the same as the movement direction of the material substrate. On the one hand, it can effectively increase the contact time between the hot air and the material substrate, thereby improving the utilization rate of the hot air. On the other hand, since the hot air has the same direction, it can effectively avoid the mutual interference between the hot air and the steam, thereby affecting the flow speed of the hot air, thereby improving the drying efficiency, thereby improving the problem of the oppositely arranged air nozzles affecting the drying efficiency of the oven in the related technology.

[0014] 2. A same-direction air nozzle structure of the utility model sets a diversion plate on the second air plate and has the same direction as the first air duct and the second air duct, and sets a plurality of diversion grooves on the diversion plate to further guide the hot air. The hot air blown out of the first air duct and the second air duct will form a more stable and efficient flow field under the guiding effect of the diversion plate, thereby further improving the drying efficiency.
