Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine drying technology, and in particular to a vacuum drying oven for traditional Chinese medicine. Background Technology

[0002] A vacuum drying oven for traditional Chinese medicine is a specialized piece of equipment that uses a vacuum environment to lower the boiling point of water, thereby rapidly drying Chinese herbal medicines at a lower temperature. By drawing a vacuum to reduce the air pressure inside the oven, the boiling point of water is lowered. Under these conditions, the material is heated, and the moisture evaporates rapidly and is then removed, thus achieving the purpose of drying.

[0003] However, in the existing technology, when drying Chinese medicine placed in the vacuum drying oven, the Chinese medicine is generally laid flat in the vacuum drying oven and left to dry, which makes it difficult for the lower surface of the Chinese medicine and some Chinese medicine that was covered during the laying process to dry, thus affecting the overall drying effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: during the drying process of traditional Chinese medicine placed in a vacuum drying oven, since the traditional Chinese medicine is generally laid flat in the vacuum drying oven and left to dry, the lower surface of the laid traditional Chinese medicine and some traditional Chinese medicine that were covered during the laying process are not easily dried, which affects the overall drying effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum drying oven for traditional Chinese medicine, comprising a vacuum drying oven body, a closing door panel rotatably connected to the opening of the drying chamber of the vacuum drying oven body, a slide rail fixed on the surface of the drying chamber of the vacuum drying oven body, and a take-up and put-down tray rotatably connected to the surface of the slide rail, a through opening on one side surface of the rear end of the take-up and put-down tray, and teeth fixedly connected to the upper surfaces of the front and rear ends of the take-up and put-down tray, an electric telescopic rod fixedly through one side of the vacuum drying oven body, a connecting ring fixedly connected to the telescopic end of the electric telescopic rod, and a rotating shaft rotatably connected to the inner surface of the connecting ring, a rolling column fixedly connected to one side of the rotating shaft, a toggle member fixedly connected to the outer surface of the rolling column, and a gear fixedly connected to one end of the rotating shaft, with the gear meshing with the teeth.

[0006] In a preferred embodiment, the surface of the closed door panel is provided with an observation opening, and an observation window is fixedly connected to the observation opening.

[0007] In a preferred embodiment, a handle is fixedly connected to the lower surface of the receiving tray.

[0008] In a preferred embodiment, a reinforcing frame is fixedly connected to the surface of the electric telescopic rod, and one end of the reinforcing frame is fixedly connected to the surface of the vacuum drying oven body.

[0009] In a preferred embodiment, the moving length of the electric telescopic rod pushing the rolling column is consistent with the length of the take-up and take-down space in the take-up and take-down tray, and the length of the rolling column and the actuating element is consistent with the width of the take-up and take-down space in the take-up and take-down tray.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention involves placing Chinese medicinal herbs on a receiving tray and pushing the tray onto a slide rail. During the vacuum drying process, the herbs are repeatedly extended and retracted by an electric telescopic rod, which in turn moves a connecting ring, rotating shaft, rolling column, actuating component, and gears back and forth on the receiving tray. The gears, aided by the teeth, rotate as they move, causing the rotating shaft, rolling column, and actuating component to rotate as well. This rotation of the actuating component flips the herbs on the receiving tray, effectively preventing parts of the herbs from being covered and hindering drying due to prolonged static placement.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a vacuum drying oven for traditional Chinese medicine, including a vacuum drying oven body 1. A closing door 2 is rotatably connected to the opening of the drying chamber of the vacuum drying oven body 1. A slide rail 4 is fixed on the surface of the drying chamber of the vacuum drying oven body 1, and a receiving tray 5 is rotatably connected to the surface of the slide rail 4. The traditional Chinese medicine to be dried is first laid flat on the receiving tray 5, and then the receiving tray 5 is completely placed into the vacuum drying space of the vacuum drying oven body 1 and connected to the slide rail 4. The slide rail 4 facilitates the layering of multiple receiving trays 5 in the vacuum drying oven body 1, so that more traditional Chinese medicine can be dried in the vacuum drying oven body 1. After the receiving trays 5 are placed on the slide rail 4, the closing door is closed. Plate 2 is tightly closed, and then the vacuum drying oven body 1 is started to dry the Chinese medicine. A through-hole 6 is provided on one side surface of the rear end of the receiving tray 5. Through the through-hole 6, the rolling column 13 can pass through the through-hole 6 into the receiving space of the receiving tray 5 during placement on the slide rail 4, preventing it from obstructing the installation of the receiving tray 5 on the slide rail 4. Teeth 7 are fixedly connected to the upper surfaces of both the front and rear ends of the receiving tray 5. An electric telescopic rod 9 is fixedly fixed through one side of the vacuum drying oven body 1. A controller for use with the electric telescopic rod 9 is installed on the vacuum drying oven body 1. By operating the controller, the electric telescopic rod 9 can be repeatedly extended and retracted. A fixed connection is made to the extension end of the electric telescopic rod 9. A connecting ring 11 is provided, and a rotating shaft 12 is mounted on the inner surface of the connecting ring 11. A rolling column 13 is fixed to one side of the rotating shaft 12. The extension and retraction of the electric telescopic rod 9 causes the connecting ring 11, the rotating shaft 12, and the rolling column 13 to move back and forth on the receiving tray 5. A toggle 14 is fixedly connected to the outer surface of the rolling column 13. A gear 15 is fixed to one end of the rotating shaft 12, and the gear 15 meshes with the teeth 7. When the rotating shaft 12 moves, it also drives the gear 15 to move. When the gear 15 moves along the teeth 7 on the receiving tray 5, it also rotates itself, thereby driving the rotation of the rolling column 13 and the toggle 14. This allows the toggle 14 to turn the Chinese medicine on the receiving tray 5. When the Chinese medicine is vacuum dried in the vacuum drying oven body 1... To ensure thorough drying, the controller on the vacuum drying oven body 1, which controls the movement of the electric telescopic rod 9, is operated to make the electric telescopic rod 9 extend and retract back and forth. The extension and retraction of the electric telescopic rod 9 drives the connecting ring 11, rotating shaft 12, rolling column 13, actuating element 14, and gear 15 to move back and forth on the receiving tray 5. With the help of the teeth 7, the gear 15 rotates as it moves, thereby driving the rotating shaft 12, rolling column 13, and actuating element 14 to rotate during the movement. The rotating actuating element 14 then flips the Chinese medicine on the receiving tray 5 back and forth, effectively preventing parts of the surface from being covered due to long-term static placement, which is not conducive to drying, and improving the drying effect of the Chinese medicine.

[0021] Example 2

[0022] like Figure 1-4 As shown, an observation opening is provided on the surface of the closed door panel 2, and an observation window 3 is fixedly connected to the observation opening. The observation window 3 allows for real-time observation of the drying process of the Chinese medicine inside the vacuum drying oven 1 during the drying process. A handle 8 is fixedly connected to the lower surface of the take-up tray 5. The handle 8 allows for easy manual control of the take-up tray 5, facilitating its removal from or placement on the slide rail 4. A reinforcing frame 10 is fixedly connected to the surface of the electric telescopic rod 9, and one end of the reinforcing frame 10 is connected to the vacuum drying oven. The surface of the drying chamber body 1 is fixedly connected. The stability of the electric telescopic rod 9 on one side of the vacuum drying chamber body 1 is improved by the setting of the reinforcing frame 10. The moving length of the electric telescopic rod 9 pushing the rolling column 13 is consistent with the length of the receiving space in the receiving tray 5. The length of the rolling column 13 and the actuating member 14 is consistent with the width of the receiving space in the receiving tray 5. In this way, when the electric telescopic rod 9 controls the rolling column 13 to move above the receiving tray 5, it ensures that the rolling column 13 moves and covers the receiving space of the receiving tray 5, so that the actuating member 14 can fully turn over the Chinese medicine placed on the receiving tray 5.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
