[0021] The dehumidification box flip mechanism 4 includes a gear 42, a rotating shaft 43 and a rack 41. The gear 42 is rotatably connected to the middle bracket of the rack 1 through the rotating shaft 43. The dehumidification box 5 is fixed to the end of the rotating shaft 43. The gear 42 and the rack 41 are meshed with each other. The dehumidification box flip mechanism 4 also includes a guide rod 46. The end of the guide rod 46 is fixedly connected to the rack 1. The rack 41 is slidably connected to the guide rod 46. The dehumidification box flip mechanism 4 also includes a screw 45 and a transmission nut 47. The screw 45 is rotatably installed on the inner side of the middle bracket of the rack 1. The transmission nut 47 is fixed to the bottom of the rack 41 and is engaged with the rack 41. The screw 45 is threadedly connected, and the dehumidification box flipping mechanism 4 also includes a handle 44, which is fixed to the outer end of the screw 45. After the dehumidification work is completed, the handle 44 is turned, and the handle 44 drives the screw 45 to rotate. The screw 45 and the transmission nut 47 are threadedly transmitted, and the transmission nut 47 drives the rack 41 to slide along the guide rod 46. The rack 41 and the gear 42 are engaged for transmission, and the gear 42 drives the dehumidification box 5 to flip through the rotating shaft 43, so that the shell of the fireworks on the upper surface of the dehumidification box 5 can be quickly removed, which avoids the trouble of removing them one by one, thereby improving production efficiency.

[0022] The exhaust unit 3 includes an exhaust fan 31, an air duct 32 and a rotary joint 33. The exhaust fan 31 is installed on the side of the frame 1 and is connected to the interior of the dehumidification box 5 through the air duct 32.

The shell of the display shell is buckled on the support mold 6. At this time, the support mold 6 positions and supports the inner surface of the shell of the display shell. Then, the exhaust fan 31 draws air in and out of the dehumidification box 5 through the air duct 32. The dehumidification box 5 drives the air outside the box body to flow through the ventilation holes 7. The accelerated air flow dehumidifies and dries the shell of the display shell. During the dehumidification process, it can support and position the inner surface of the shell of the display shell, thereby preventing it from shrinking and deforming during the dehumidification operation, thereby ensuring the product yield. When the dehumidification box 5 is turned over, it rotates relative to the air duct 32 through the rotary joint 33.

[0023] The working principle of the display shell drying and dehumidifying device provided by the present invention is as follows: the display shell is buckled on the support mold 6. At this time, the support mold 6 positions and supports the inner surface of the display shell. Then, the exhaust fan 31 draws air in and out of the dehumidification box 5 through the air duct 32. The dehumidification box 5 drives the air outside the box body to flow through the ventilation holes 7, and the display shell is dehumidified and dried by accelerating the flow of air. After the dehumidification work is completed, the handle 44 is turned, and the handle 44 drives the screw 45 to rotate. The screw 45 and the transmission nut 47 are threadedly driven.
