[0024] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] As shown in the figure, a vacuum drying oven for drying medicines includes a box body 1 and an opening and closing door (not shown in the figure) located on the front side of the box body 1. A rotating rod 2 capable of rotating along the axis is vertically provided in the middle inside the box body 1. A plurality of brackets 7 are arranged at intervals on the rotating rod 2. Each bracket 7 is provided with a tray assembly 3. The tray assembly 3 includes a first tray 301 and a second tray 302 docked together. A through hole is opened in the middle of the docking part of the first tray 301 and the second tray 302. The rotating rod 2 passes through the through hole. The bracket 7 includes an annular connecting platform 701 fixed on the rotating rod 2. A plurality of supporting rods 702 are clamped at the bottoms of the first tray 301 and the second tray 302. The plurality of supporting rods 702 are uniformly fixed on the circumferential direction of the connecting platform 701. An adjusting rod 4 is also vertically fixed inside the box body 1. On the side of the adjusting rod 4 facing the tray assembly 3, a foldable movable scraper 6 is provided corresponding to the upper side of each tray assembly 3. When the movable scraper 6 is folded to the horizontal state, the front part straddles inside the corresponding tray assembly 3. In this embodiment, a plurality of layers of rotatably connected tray assemblies 3 are arranged inside the box body 1, which is more conducive to drying. The tray assembly 3 is set as a structure in which the first tray 301 and the second tray 302 are docked on the rotating rod 2 and are carried by the bracket 7, which is convenient for disassembly and assembly. It is convenient for the operator to place the medicines to be dried on the tray assembly 3 and also convenient to remove the tray assembly 3 to pour out the dried medicines. At the same time, a foldable movable scraper 6 is provided corresponding to each tray assembly 3 inside the box body 1. During drying, if it is necessary to turn the medicines, the movable scraper 6 is folded to the horizontal state to be inside the tray assembly 3. As the tray assembly 3 rotates, the medicines are turned, making the medicines dry more quickly and effectively improving the drying efficiency. When it is necessary to remove the tray assembly 3, the movable scraper 6 is folded upward to move it away from the tray assembly 3.

[0026] Both the first tray 301 and the second tray 302 are semi-circular structures. The inner edge of the docking end of the first tray 301 is provided with a first U-shaped groove 303, and the outer edge of the docking end of the second tray 302 is provided with a second U-shaped groove 304. The first tray 301 and the second tray 302 are docked into a disc structure, and the inner edge of the docking end of the second tray 302 is lapped in the first U-shaped groove 303. The outer edge of the first tray 301 is inserted at the second U-shaped groove 304. First semi-circular holes 305 and second semi-circular holes 306 are respectively opened in the middle of the docking ends of the first tray 301 and the second tray 302. The first semi-circular hole 305 and the second semi-circular hole 306 are docked together to form a through hole. In this embodiment, the first tray 301 and the second tray 302 are lapped together through the edges at the docking ends with the corresponding U-shaped grooves, and the docking is more stable. And a double stop surface is formed by the first U-shaped groove 303 and the second U-shaped groove 304, which plays a certain sealing effect and avoids the medicines in the tray assembly 3, especially the powder medicines, from leaking out from the gap between the first tray 301 and the second tray 302.

[0027] The support rod 702 is an L-shaped structure arranged in a horizontal plane, and the vertical section of the support rod 702 is clamped at the circumferential outer wall of the first tray 301 and the second tray 302, and the first tray 301 and the second tray 302 are fixedly connected with a clamping block 307 at both sides of the vertical section of each support rod 702 on the circumferential outer wall, and the vertical section of the support rod 702 is clamped between the corresponding two clamping blocks 307. In this embodiment, the tray assembly 3 is horizontally limited by the vertical section of the support rod 702, and the tray assembly 3 is circumferentially limited by the cooperation between the clamping block 307 and the vertical section of the support rod 702, so as to ensure that the tray assembly 3 forms a relatively fixed structure with the rotating rod 2 after being installed on the rotating rod 2, and also ensure that the first tray 301 and the second tray 302 will not separate during the rotation process.

[0028] There are four supporting rods 702 , which are arranged in an X-shape in the circumferential direction of the connecting platform 701 , which can support the tray assembly 3 more stably while reducing the weight of the bracket 7 .

[0029] A U-shaped connecting block 5 is horizontally fixedly connected to each movable scraper 6 on the connecting rod 4, and a hollow hole 501 is opened in the middle of the bottom of the connecting block 5. The rear of the movable scraper 6 is located in the connecting block 5, and the end of the movable scraper 6 is located on the upper side of the hollow hole 501 and is rotatably connected with the side plates on both sides through the connecting shaft. In this embodiment, the movable scraper 6 can be rotated to a vertical state along the connecting shaft. At this time, the end of the movable scraper 6 extends downward into the hollow hole 501. The hollow hole 501 is provided to enable the movable scraper 6 to rotate smoothly and avoid constraining it; after the movable scraper 6 is flipped to a vertical state or the upper end is tilted and leaned on the connecting rod 4, the separation of the movable scraper 6 and the tray assembly 3 is completed, and the tray assembly 3 can be taken and placed at this time; when the tray assembly 3 is installed in place on the bracket 7, the movable scraper 6 is flipped to a horizontal state, and the rear of the movable scraper 6 is overlapped in the connecting block 5 to achieve horizontal positioning.

[0030] A plurality of scraping blocks 601 are fixed downwardly to the bottom front side of the movable scraper 6. When the movable scraper 6 is in a horizontal state, the scraping blocks 601 extend into the tray assembly 3. In this embodiment, when the tray assembly 3 rotates with the rotating rod 2, the medicine to be dried in the tray can be turned over by the scraping blocks 601, thereby increasing the drying efficiency.

[0031] A motor 8 is fixedly connected to the top of the box body 1 , and the output shaft of the motor 8 is fixedly connected to the rotating rod 2 , so that the rotating rod 2 is driven to rotate by the motor 8 .

[0032] A mounting platform 101 is fixedly connected to the bottom of the inner side of the box body 1, and the lower end of the rotating rod 2 is connected to the mounting platform 101 through a bearing.

[0033] The working process of this embodiment is as follows:

[0034] The tray assembly 3 is installed on the bracket 7, and capsule medicines are placed therein. The tray assembly 3 can be rotated during the process of placing the medicines to make the medicines placed more evenly; then the movable scraper 6 is folded to a horizontal state, and the movable scraper 6 is supported by the connecting block 5 to make it in a horizontal state; the motor 8 is started to drive the rotating rod 2 to rotate, driving the tray assembly 3 to rotate slowly, and at the same time the scraper block 601 turns the medicines to make the drying more uniform, thorough and fast; when the drying is completed and the medicines need to be taken out, the movable scraper 6 is folded upward to be upright or leaned on the connecting rod 4 to separate it from the tray assembly 3. Before taking out the tray assembly 3, the medicines in the tray assembly 3 are divided to the first tray 301 and the second tray 302 sides to prevent the medicines from falling when the first tray 301 and the second tray 302 are separated; the tray assembly 3 is lifted up to separate it from the bracket 7, and then the first tray 301 and the second tray 302 are separated to both sides, and the medicines are poured into the collection frame.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
