[0022] In this embodiment, the workbench 1, the drying box 2, the electric hot air blower 3 and the fixing frame 4 constitute the main structure of the food packaging box rapid drying equipment involved in this application.

[0023] Specifically, the conveyor belt 11 has a structure with a limiting plate on the surface, so that it has an equidistant limiting effect on the packaging boxes placed thereon. At the same time, the intermittent movement of the conveyor belt 11 is controlled by an external controller, so that the packaging boxes can accurately stay on the lower side of the movable tube 35.

[0024] Specifically, both sides of the drying box 2 are set to be open, so that the evaporated moist gas can be quickly diffused out during drying.

[0025] like Figure 2 and Figure 3 As shown, the air outlet end of the electric hot air blower 3 is connected with a tee, and the outer end of the tee is connected to the transverse pipe 34 through a hose 31, and the hose 31 is slidably connected in the slide groove inside the side panel, and the upper end of the transverse pipe 34 is connected with a guide rod 41, and the guide rod 41 slides through the upper top plate of the fixing frame 4, and the two ends of the air inlet pipe 33 are connected with straight pipes 32, and the straight pipe 32 is connected to the tee on the outside of the electric hot air blower 3, and the inner side of the air inlet pipe 33 is connected with a connecting pipe 331, and the inner end of the connecting pipe 331 is connected with an air outlet 332, and the connecting pipes 331 are arranged at equal intervals along the length direction of the air inlet pipe 33, and the connecting pipes 331 are inserted into the inner wall of the drying box 2, and the air outlet 332 is set as a bell-mouth structure.

At this time, the air inlet pipe, connecting pipe and air outlet connected to the electric hot air blower are used to blow and heat the outside of the packaging box, and at the same time, the inside of the packaging box is blown and heated through the horizontal pipe, movable pipe, air holes and installation box. When the humidity of the packaging box is low, the installation box can be placed on the inside of the drying box near the top through the hydraulic rod, so that the packaging box passes continuously from the bottom of the installation box. At this time, the hot air is diffused into the interior of the drying box through the air holes on the outside of the movable pipe, and at the same time, the fan blades in the installation box are blown and rotated by the hot air flow, so that the hot air blows downward to the continuously transported packaging boxes, thereby realizing rapid drying of the packaging boxes without stopping the conveyor belt.
