The working principle is as follows: when the food propaganda diagram needs to be pasted, any one of the sealing doors 41 is opened, so that the food propaganda diagram enters the sealing cover 4 from the through opening, the food propaganda diagram is attached to the surface of the conveyor belt 3, and the food propaganda diagram is pasted on the surface of the conveyor belt 3;
when the propaganda needs to be carried out, the motor is started, the conveyor belt 3 is further driven to move, the food propaganda picture is driven to rotate, the light supplement lamp 5 is started at the same time, the luster of the food propaganda picture is increased, people around the propaganda board can watch the food propaganda picture from the three-side light-transmitting area, and therefore the food propaganda effect is achieved;
when the inside of the sealing cover 4 needs to be dried, the fan 61 is started, so that outside air is filtered through the filter screen 621, and then enters the sealing ring 634 through the communicating pipe 64, and further the pushing plate 636 is pushed to rotate along the central axis of the rotating shaft 635, and finally the air is discharged from the air outlet hole and enters the U-shaped box 631, and further contacts with a drying agent in the placing box 633 through the air vent at the bottom of the placing box 633, and is further discharged from the top end of the placing box 633, and further enters the sealing cover 4 through the air vent at the top end of the top cover 632, so that the air rises from the triangular part at the bottom end of the sealing cover 4 to the middle part at the top end of the sealing cover 4, and further enters the fan 61 and is discharged from the air outlet hole of the fan 61, thereby the temperature difference between the inside and the outside of the sealing cover 4 is relieved, and water vapor is prevented from occurring in the inside of the sealing cover 4;
in the process of rotation of the push plate 636, when the push plate 636 is in contact with the sliding plate 637, the sliding plate 637 is jacked up to enable the sliding plate 637 to slide out of the sealing ring 634, further jack up the placing box 633 to extrude the first return spring, and when the push plate 636 is separated from the sliding plate 637, the first return spring drives the placing box 633 to move downwards to return, so that the drying agent in the placing box 633 generates vibration, and further the wind is fully contacted with the drying agent, so that the wind drying efficiency is improved;
wherein, the wind exhausted from the exhaust hole of the fan 61 enters the air box 661 to push the blade 663, so that the rotating rod 662 rotates, the wind enters the air storage ring 665 from the air duct 664, and then enters the air vent groove in the rotating rod 662 through the air vent, and then enters the fixed box 667, and then enters the hose 654 through the fixed pipe 668, and finally the wind in the hose 654 is exhausted through the blowing pipe 651 to blow the dust on the outer surface of the sealing cover 4;
when the rotating rod 662 rotates, the fixed box 667 is driven to rotate, so that the fixed pipe 668 rotates, the positioning plate 655 rotates, the guide seat 656 rotates, the sliding rod 657 in the guide seat 656 drives the roller 653 to be always tightly attached to the inner surface of the top cover 67 under the action of the second return spring, so that the blowing pipe 651 is always rotated along the outer surface of the upper part of the seal cover 4, and dust on the outer surface of the seal cover 4 is blown;
when the filter screen 621 needs to be cleaned, the fixed plate 622 is taken down, the filter screen 621 in multiple sections is taken out, the filter screen 621 is cleaned through clean water and dried, and further, the filter screen 621 is installed according to the reverse operation of the operation of taking down the filter screen 621;
when the drying agent needs to be replaced, the three sealing doors 41 are opened in sequence, then the three top covers 632 are taken down in sequence, then the three storage boxes 633 are drawn out, at this time, the storage boxes 633 can be replaced directly, or the storage boxes 633 are opened, the old drying agent is poured out, the new drying agent is filled, and further, the drying agent is installed according to the reverse operation of the replacement operation.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
