[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5The utility model provides an embodiment: a drying box with excellent sealing, including a box body 10 and a cover plate 20. The box body 10 is provided with an opening 11, and the opening 11 is the main passage for materials to enter. The box body 10 is used in conjunction with the cover plate 20. A propulsion module 30 is provided at the side end of the box body 10. The driving end of the propulsion module 30 is connected with a gear group transmission module 40. The gear group transmission module 40 is connected to the cover plate 20. The gear group transmission module drives the cover plate to rotate and makes the cover plate 20 parallel to the opening of the box body. Then, through the propulsion module 30, the gear group transmission module 40 and the cover plate 20 connected thereto are driven to approach and fit with the corresponding end surface of the box body 10. The cover plate 20 can completely cover the opening 11 to form a sealed cavity, which further improves the sealing effect of the drying box.

[0023] A drying system 50 is also provided on one side of the box body 10. The drying system 50 is communicated with the inner cavity of the box body 10, and the drying system 50 dries the material in the cavity.

[0024] In this embodiment, the propulsion module 30 is a propulsion cylinder; the propulsion module 30 may also be other linear drive modules.

[0025] The gear transmission module 40 includes a mounting frame 41, a rotating mechanism 42 arranged on the mounting frame 41, and a rotating shaft 43 rotatably connected to the mounting frame 41, wherein the rotating shaft 43 is fixedly connected to the cover plate 20, a synchronous gear 44 is arranged on the top of the rotating shaft 43, and a driving gear 45 is connected to the driving end of the rotating mechanism 42. The driving gear 45 is linked to the synchronous gear 44, that is, when the rotating mechanism 42 drives the driving gear 45 to rotate, it can drive the cover plate 20 to rotate in the forward or reverse direction, so as to realize that the box body 10 and the cover plate are parallel to each other.

[0026] An auxiliary gear 46 is provided between the driving gear 45 and the synchronous gear 44. The auxiliary gear 46 is rotatably connected to the mounting frame 41. Both ends of the auxiliary gear 44 are respectively meshed with the driving gear 45 and the synchronous gear 44. The auxiliary gear 44 can reduce the speed ratio of the rotating mechanism 42, so that the cover plate 20 rotates slowly to prevent the speed from being too fast, which may cause damage to the box body 10 or the cover plate 20. In addition, the distance between the rotating mechanism 42 and the cover plate 20 can be increased by the auxiliary gear 44, so that the overall structure can be more reasonable.

[0027] In this embodiment, the rotating mechanism 42 is a rotating cylinder; the rotating mechanism 42 may also be other rotating drive modules.

[0028] Two bearings 47 are provided on the mounting frame 41, and the two bearings 47 are respectively sleeved with the two ends of the rotating shaft 43. The mounting frame 41 and the rotating shaft 43 are rotatably connected through the two bearings 47, which improves the flowability of the rotating shaft 43 during rotation, reduces wear, and increases the service life of the drying box.

[0029] A socket 48 is installed at the bottom of the rotating shaft 43, and an extension portion 49 is extended outward from the socket 48. Two stop portions 411 are provided on the mounting frame 41. The two stop portions 411 are located on both sides of the socket 49, and the two stop portions 411 are arranged parallel to each other. The two stop portions 411 are mainly used to limit the rotation range of the rotating shaft 43 to 180 degrees to prevent the rotation range from deviation.

[0030] When the door is opened, the pushing module 30 pushes the gear group transmission module 40 and the cover plate 20 outward, and the cover plate 20 rotates 18 degrees without affecting the adjacent box.

[0031] Two sensors 412 are also provided on the mounting frame 41 . The two sensors 412 are respectively located below the two stopper portions 411 . The sensors 412 can sense the upper extension portion 49 , so that the system can determine whether the door is in an open state or a closed state.

[0032] A sealing strip 21 is provided on the end surface of the cover plate 20 close to the opening 11 . The sealing strip 21 is annular and contacts the front end surface of the box body 10 . The sealing strip 21 surrounds the circumference of the opening 11 , further improving the sealing performance between the cover plate 20 and the box body 10 .

[0033] A magnetic attraction component is provided in the sealing strip 21 (not shown), and the magnetic attraction component is adsorbed and connected to the box body 10, further improving the fit between the sealing strip 21 and the box body 10, and making the cover plate 20 and the box body 10 have a force of adsorption on each other, preventing the cover plate 20 and the box body 10 from being easily detached from each other, resulting in reduced sealing effect.
