The drying agents can absorb moisture in the tableware through the air holes in the inner wall of the moving plate 3 and the air holes on the side of the storage box 32 to prevent bacteria from breeding due to residual water stains after cleaning the tableware. When the storage box 32 enters the moving plate 3, the storage box 32 will drive the rotating block 621 to rotate, the rotating block 621 will drive the elastic rod 622 to deform and arch, the elastic rod 622 will drive the stirring rod 623 to displace, and the stirring rod 623 will stir the drying agents, thereby increasing the contact area of the drying agents and the moisture and improving the drying effect of the tableware.

[0030] The working principle is that in the food heat preservation process of the rotational molding box, the heating plate 52 in the supporting plate 42 is started, and the battery pack 51 provides power for the heating plate 52, so that the heating plate 52 is always started and provides heat preservation for the food on the supporting plate 42, and the food can be further heat preserved; when the supporting plate 42 moves out of the box body 1, the spring resets the clamping plate two 425, the clamping plate two 425 resets the push rod 426, the push rod 426 pushes the arc-shaped rod 424 to rotate and reset, and the arc-shaped rod 424 resets the transmission plate 522 by the inclined surface to push the transmission plate 522 upwards, the transmission plate 522 drives the baffle 521 to move upwards and blocks the through hole on the supporting plate 42, so that the dust in the external environment cannot enter the supporting plate 42 through the through hole, and the dust cannot pollute the food in the subsequent storage process; when the supporting plate 42 enters the box body 1, the arc-shaped rod 424 rotates under the pushing of the transmission rod 423, at this time, the inclined surface on the arc-shaped rod 424 no longer limits the transmission plate 522, at this time, the stretching spring 523 drives the transmission plate 522 to move downwards, so that the baffle 521 on the transmission plate 522 is away from the through hole, at this time, the through hole on the supporting plate 42 is opened, so that the heat emitted by the heating plate 52 on the inner wall of the supporting plate 42 can enter the rotational molding box through the through hole.

[0031] When the storage box 32 is placed and reset after placing the tableware, the elastic multi-stage telescopic rod 61 in the moving plate 3 drives the push plate 62 to move in the reset storage box 32, the push plate 62 pushes the tableware to move in the storage box 32 and gathers in front of the storage box 32, when the tableware is more, the push plate 62 cannot continue to push the tableware to move, at this time, the elastic multi-stage telescopic rod 61 is retracted, so that the storage box 32 can be completely reset, and the push plate 62 can gather and limit the tableware, so that the tableware in the storage box 32 is prevented from shaking and generating noise, and the drying agent is also placed in the moving plate 3, the drying agent can absorb the moisture in the tableware through the air holes in the inner wall of the moving plate 3 and the air holes on the side of the storage box 32, so that the bacteria breeding by the residual water stains of the tableware after cleaning is prevented, when the storage box 32 enters the moving plate 3, the storage box 32 drives the rotating block 621 to rotate, the rotating block 621 drives the elastic rod 622 to be deformed and arch, the elastic rod 622 drives the stirring rod 623 to displace, and the stirring rod 623 stirs the drying agent, so that the contact area of the drying agent and the moisture is increased, and the drying effect of the tableware is improved.
