[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0026] In some embodiments, please refer to the accompanying drawings. Figures 1-4A structure for uniformly curing tobacco leaves in a tobacco curing barn includes a curing barn 1, a fixed annular plate 2, a self-rotating circulating frame transfer mechanism 3, a vertical reciprocating motion mechanism 4, and a hanging frame 5. The fixed annular plate 2 is fixedly installed on the inner top of the curing barn 1 by support columns. The fixed annular plate 2 is equipped with a self-rotating circulating frame transfer mechanism 3 for controlling the movement of the hanging frame 5 and rotating during the movement to achieve uniform curing of tobacco. The self-rotating circulating frame transfer mechanism 3 includes a drive assembly 31 for controlling the movement of the moving plate 33 and a mechanism for controlling the movement of the hanging frame 5. The rotating component 32 rotates during operation; the drive component 31 is installed on the upper end of the fixed plate annular plate 2, and multiple moving plates 33 are installed on the drive component 31, and the rotating component 32 is connected to the up-and-down reciprocating motion mechanism 4; the rotating component 32 is installed on the moving plates 33; and the hanging bracket 5 is installed on the rotating component 32; the lower end of the fixed plate annular plate 2 is equipped with the up-and-down reciprocating motion mechanism 4 for controlling the up-and-down movement of the hanging bracket 5; the front middle position of the fixed plate annular plate 2 is set as the loading and unloading station; the baking chamber 1 is made of heat-insulating material.

[0027] In this invention, the operator hangs tobacco on the racks 5 at the loading / unloading station using the auxiliary feeding device. Then, the drive assembly 31 moves the moving plate 33, and the next moving plate 33 moves to the loading / unloading station to continue hanging tobacco on the racks 5 until all the racks 5 connected to the moving plates 33 are loaded with tobacco. Then, the tobacco roasting operation can begin. During tobacco roasting, the drive assembly 31 drives all the racks 5 to move simultaneously and at a uniform speed. During this movement, the rotation assembly 32 rotates the racks 5 together, causing them to rotate. The tobacco on all racks 5 in the same batch receives a uniform roasting effect, effectively improving the quality of tobacco roasting and ensuring product consistency. The reciprocating motion mechanism 4 keeps the rack 5 at its lowest point at the loading and unloading station, facilitating the hanging of tobacco. When the tobacco is hung up and moves with the rotating component 32, the reciprocating motion mechanism 4 causes the rotating component 32 to move upward. At this time, the rack 5 moves upward with the rotating component 32, bringing the tobacco to a higher position, so that the tobacco receives more uniform heat during roasting, improving the practicality of the device.

[0028] The drive assembly 31 includes an annular guide rail 311, a drive gear disk 312, a driven gear disk 313, a synchronous chain 314, and rollers 315. The annular guide rail 311 is fixedly installed on the upper end of the fixed plate annular plate 2. The drive gear disk 312 is rotatably disposed on the upper left side of the fixed plate annular plate 2. The driven gear disk 313 is rotatably disposed on the upper right side of the fixed plate annular plate 2. The outer ends of the drive gear disk 312 and the driven gear disk 313 are wound with the synchronous chain 314 to enable transmission connection between the two. Multiple movable plates 33 are fixedly installed on the synchronous chain 314. The rollers 315 are rotatably installed on the lower end of the movable plates 33 and are in rolling connection with the annular guide rail 311.

[0029] The drive gear 312 can be driven by a motor;

[0030] The self-rotating assembly 32 includes a fixed chain 321, a rotating gear 322, and a connecting shaft 323. The fixed chain 321 is fixedly mounted on the annular plate 2 of the fixed plate by a bracket, and the mounting position of the fixed chain 321 is above the synchronous chain 314. The rotating gear 322 is rotatably mounted on the movable plate 33. The connecting shaft 323 is keyed to the rotating gear 322. The rotating gear 322 is meshed with the fixed chain 321. A bracket 5 is fixedly mounted on the lower end of the connecting shaft 323.

[0031] In this invention, the drive gear 312 rotates, causing the synchronous chain 314 to rotate, which in turn causes the driven gear 313 to rotate. At this time, multiple moving plates 33 will follow the roller 315 to move cyclically around the annular guide rail 311. During the movement, the rotating gear 322 causes the fixed chain 321 to rotate. The rotation of the fixed chain 321 drives the connecting shaft 323 to rotate. At this time, the hanging rack 5 will rotate along with the connecting shaft 323, so that the tobacco hanging on the hanging rack 5 is evenly roasted.

[0032] The reciprocating motion mechanism 4 includes an annular plate 41, a guide wheel 43, and a support rod 44. The annular plate 41 is fixedly installed at the lower end of the fixed plate annular plate 2. A guide groove 42 is provided in the middle of the annular plate 41. The guide groove 42 is wavy and has its lowest point at the loading / unloading station. The middle part of the connecting shaft 323 is rotatably connected to the support rod 44. The guide wheel 43 is rotatably installed at the inner end of the support rod 44 and is in rolling connection with the guide groove 42. The support rod 44 is fixedly connected to the moving plate 33 through a connecting rod.

[0033] In this invention, when the guide wheel 43 leaves the lowest point of the guide groove 42, it will roll along the guide groove 42. At this time, the guide wheel 43 will drive the support rod 44 to move upward together. Since the connecting shaft 323 is keyed to the rotating gear 322, the connecting shaft 323 will move upward together with the support rod 44, driving the hanging rack 5 to move upward together. This makes the tobacco receive more even heat when it moves upward, improving the roasting effect. When the roasting is completed, the guide wheel 43 returns to the lowest point. At this time, the connecting shaft 323 drives the hanging rack 5 to descend, making it convenient for the operator to remove the roasted tobacco from the hanging rack 5.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
