[0054] In order to be applicable to waterproof corrugated cartons of different models, when the dried waterproof corrugated carton is small, the driving motor 51 is started to drive the rotating shaft 52 to rotate, and under the action of the screw thread 522, the rotating sleeve 53 drives the first bevel gear 54 to move to the side close to the driving motor 51. When the first bevel gear 54 meshes with the second bevel gear 55, the rotating sleeve 53 stops moving because the sliding block 531 on the rotating sleeve 53 abuts against the inner wall of the sliding groove 521, and the rotating shaft 52 drives the first bevel gear 54 to rotate, thereby driving the second bevel gear 55 to rotate, and further driving the bidirectional lead screw 41 to rotate. The rotation of the bidirectional lead screw 41 causes the two sliding plates 42 to move close to each other, and the movement of the sliding plates 42 drives the long plate 43, the three supporting rods 331 and the moving plate 31 to move close to each other. When the moving plate 31 is located on the side of the waterproof corrugated carton, the driving motor 51 is turned off to stop the movement of the moving plate 31. At this time, the conveyor belt 11 and the plurality of heating pipes 34 are started, so that the waterproof corrugated carton can be conveyed and dried at the same time. Then the exhaust fan 12 is turned on to exhaust the water vapor generated during the drying of the waterproof corrugated carton. Then the driving motor 51 is started to drive the rotating shaft 52 to reverse, so that the rotating sleeve 53 moves away from the driving motor 51, and the movement of the rotating sleeve 53 drives the first bevel gear 54 to move, so that the first bevel gear 54 is separated from the second bevel gear 55. At the same time, the rotating sleeve 53 drives the first linkage rod 82, the moving rod 81 and the second linkage rod 83 to move. The movement of the second linkage rod 83 drives the sliding rod 841 to move close to the rotating cylinder 77. When the sliding rod 841 is inserted into the second blind hole 771, the rotating shaft 52 drives the sliding rod 841 to rotate under the action of the protrusion 842. Similarly, the rotation of the sliding rod 841 can drive the rotating cylinder 77 and the rotating disc 71 to rotate under the action of the long strip 843. The rotation of the rotating disc 71 drives the transmission rod 72 to move, and the movement of the transmission rod 72 drives the rack 74 to move, thereby driving the spur gear 73 and the mounting shaft 63 to rotate. Under the action of the rack 74, when the rotating disc 71 rotates by 180 degrees, the spur gear 73 also rotates by 180 degrees. When the waterproof corrugated carton moves to the end of the drying box 2, the sealing plate 62 no longer abuts against the drying box 2, so that the waterproof corrugated carton can be separated from the drying box 2. At this time, the waterproof corrugated carton to be dried can be placed on the conveyor belt 11. Because the rotation of the spur gear 73 is driven by the rack 74, the rotation speed of the spur gear 73 and the mounting shaft 63 is slow, thereby facilitating the placement of the waterproof corrugated carton in the drying box 2. During the movement of the waterproof corrugated carton along one end of the drying box 2 to the other end, one of the sealing plates 62 slowly closes the drying box 2, and then slowly separates from one side of the drying box 2. When the sealing plate 62 completely separates from one side of the drying box 2, the waterproof corrugated carton is separated from the drying box 2.

[0055] The implementation principle of the drying device suitable for waterproof corrugated carton production is as follows: the waterproof corrugated carton to be dried is placed in the drying box 2, then the drying mechanism 3 is used for drying, and meanwhile the sealing mechanism 6 is used to reduce the possibility of heat emission in the drying box 2.

[0056] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
