[0001] This utility model relates to the field of drying oven technology, specifically a rapid temperature control mechanism for a vacuum drying oven. Background Technology

[0002] Vacuum drying ovens are designed specifically for drying heat-sensitive, easily decomposed, and easily oxidized substances. During operation, they maintain a certain degree of vacuum within the working chamber and can be filled with inert gas. They are particularly suitable for rapidly drying complex items. The temperature is set, displayed, and controlled using an intelligent digital temperature controller.

[0003] An investigation revealed that a utility model patent (publication number: CN221036545U) discloses a rapid temperature control mechanism for a vacuum drying oven. The mechanism includes a vacuum drying oven containing a gas storage bottle. A fixed plate is fixedly connected to the bottom wall of the vacuum drying oven. A rotating assembly is mounted on the fixed plate, and a placement plate is fixedly connected to the rotating assembly. A clamping assembly is mounted on the placement plate. This utility model experimental device solves the problems of existing rapid temperature control mechanisms for vacuum drying ovens, which are inconvenient for simultaneously drying different types of items, reducing the utilization rate of the vacuum drying oven. Furthermore, this device is not conducive to achieving rapid temperature control within the vacuum drying oven, easily leading to uneven heating of the items in the early stages of drying, reducing the drying efficiency of the vacuum drying oven, and significantly reducing its practicality.

[0004] Although the aforementioned patent connects multiple layers of placement plates to a rotating assembly, achieving constant temperature treatment inside the drying oven and uniform heating of the dried items through the rotation of the placement plates, the placement plates are designed as a single unit. In actual use, the spacing between the upper and lower placement plates cannot be adjusted for adaptability. Furthermore, the placement plates cannot be individually pulled out or disassembled, which makes it difficult to place the dried items due to the small distance between the upper and lower placement plates.

[0005] Therefore, this utility model provides a rapid temperature control mechanism for a vacuum drying oven to solve the above problems. Utility Model Content

[0006] This invention provides a rapid temperature control mechanism for a vacuum drying oven, aiming to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid temperature control mechanism for a vacuum drying oven, comprising a box body, wherein a partition is provided inside the box body, and a support plate is fixedly connected to the inner wall of the partition, and a main shaft is rotatably provided at the center of the partition. A support frame is inserted between adjacent support plates, and a placement plate is rotatably provided at the center of the support frame. A positioning ring is integrally formed at the center of the placement plate, and the positioning ring abuts against the outer wall of the main shaft. The positioning ring is threadedly connected to the main shaft through a bolt.

[0008] As a preferred technical solution of this application, damping plates are fixedly connected to both the upper and lower ends of the front of the partition, and a baffle is provided between the partition and the damping plates for damping sliding, and the baffle is used for the abutment and positioning of the support frame.

[0009] As a preferred technical solution of this application, the front side of the spindle is provided with threaded holes, and the distance between adjacent threaded holes is equal to the distance between adjacent support plates. The support plates are symmetrically distributed on both sides of the spindle.

[0010] As a preferred technical solution of this application, the support frame is provided with a first positioning hole on its circumference, the support frame and the placement plate are provided with rectangular grooves at the corresponding main shafts, and the placement plate is provided with a second positioning hole on its circumference.

[0011] As a preferred technical solution of this application, it also includes a positioning screw, the top of which is fixedly connected to a clamping plate, and the external thread of the positioning screw is connected to a hand-tightening sleeve.

[0012] As a preferred technical solution of this application, the positioning screw can be inserted into the interior of the first positioning hole or the second positioning hole, and the hand-tightening screw sleeve is correspondingly abutted against the upper and lower ends of the support frame or the placement plate.

[0013] The beneficial effects of this application are as follows: This utility model utilizes the cooperation between the placement plate and the support frame, allowing the placement plate to be rotatably connected inside the support frame. By adjusting the support frame up and down, the spacing between adjacent placement plates can be adjusted, thereby improving its flexibility of use. At the same time, the pull-out adjustment of the support frame can pull out the corresponding placement plate, making it convenient to place dried items on the placement plate.

[0014] This utility model uses a positioning ring on the placement plate, which allows the positioning ring to be threaded through the main shaft and positioned by a hand-tightened bolt.

[0017] 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.

[0018] like Figure 1-4 As shown, this utility model provides a rapid temperature control mechanism for a vacuum drying oven, including a box body 1. A partition 11 is provided inside the box body 1, and a support plate 12 is fixedly connected to the inner wall of the partition 11. A main shaft 15 is rotatably mounted at the center of the partition 11. A support frame 2 is inserted between adjacent support plates 12, and a placement plate 3 is rotatably mounted at the center of the support frame 2. A positioning ring 32 is integrally formed with the center of the placement plate 3, and the positioning ring 32 abuts against the outer wall of the main shaft 15. The positioning ring 32 is threadedly connected to the main shaft 15 via a through bolt. The support frame 2 and support plate 12 can be quickly assembled and disassembled through a pull-out installation. Furthermore, the spacing between adjacent support frames 2 can be adjusted by inserting them at different positions, further enhancing the adaptability of the system. This design further enhances the flexibility of the device. The rotatable connection between the support frame 2 and the placement plate 3 allows the placement plate 3 to rotate when it is fixedly installed with the main shaft 15. The rotation of the main shaft 15 drives the placement plate 3 to rotate, while the support frame 2 provides auxiliary limiting for the placement plate 3, ensuring its rotational stability. The positioning ring 32 assists in positioning the support frame 2 and placement plate 3 during installation. When the positioning ring 32 abuts against the outer wall of the main shaft 15, the support frame 2 is securely installed. Rotation of the central hand-tightening bolt of the positioning ring 32 connects the bolt to the threaded hole on the front of the main shaft 15, ensuring the seamless integration of the positioning ring 32 and the main shaft 15.

[0019] Furthermore, damping plates 13 are fixedly connected to both the upper and lower ends of the front side of the partition 11, and a baffle 14 is provided between the partition 11 and the damping plate 13 for damping sliding. The baffle 14 is used for the abutment and positioning of the support frame 2. By moving the baffle 14 horizontally, when the baffle 14 abuts against the front side of the support plate 12, it can simultaneously abut and position the support frame 2, preventing the support frame 2 from sliding back and forth. The depth of the support frame 2 is equal to the length of the support plate 12.

[0020] Furthermore, the front of the main shaft 15 is provided with threaded holes, and the distance between adjacent threaded holes is equal to the distance between adjacent support plates 12. The support plates 12 are symmetrically distributed on both sides of the main shaft 15. A servo motor is connected to the bottom of the housing 1 for driving and controlling the main shaft 15. The main shaft 15 is driven to rotate by the servo motor, and the placement plate 3 fixed outside the main shaft 15 rotates in a circular motion. By adjusting the circular rotation of the placement plate 3, the gas inside the housing 1 can be disturbed, thereby making the temperature inside the housing 1 quickly constant. The rotation adjustment of the placement plate 3 can also ensure that the items placed on it are heated evenly, ensuring the uniformity of drying.

[0021] Furthermore, the support frame 2 has a first positioning hole 21 on its circumference, and the support frame 2 and the placement plate 3 have rectangular slots at the corresponding positions of the main shaft 15. The rectangular slots facilitate the disassembly and adjustment of the support frame 2 and the placement plate 3. The placement plate 3 has a second positioning hole 31 on its circumference.

[0022] Furthermore, it also includes a positioning screw 4, with a clamping plate 41 fixedly connected to the top of the positioning screw 4. A hand-tightening sleeve 42 is threadedly connected to the external side of the positioning screw 4. The positioning screw 4 can be inserted into the first positioning hole 21 or the second positioning hole 31, and the hand-tightening sleeve 42 abuts against the upper and lower ends of the support frame 2 or the placement plate 3, improving the installation flexibility of the positioning screw 4. When the positioning screw 4 is fixedly installed with the placement plate 3, it ensures that the positioning screw 4 rotates synchronously with the circumferential rotation of the placement plate 3. The positioning screw 4 can be height adjusted by clamping with the hand-tightening sleeve 42, so that the extension height of the positioning screw 4 can be flexibly adjusted. This allows the clamping plate 41 to better adapt to the height of the dried items for adjustment, thereby further improving the adaptability and flexibility of the device. Through the installation of the positioning screw 4 on the placement plate 3, the clamping plate 41 can ensure the stability of the items when clamping them, especially when the placement plate 3 rotates, preventing the dried items from shifting.

[0023] Working principle: First, the support frame 2 is pulled out, and the items to be dried can be placed on the placement plate 3. Then, the support frame 2 is inserted into the support plate 12. At the same time, the positioning ring 32 and the main shaft 15 are installed and fixed by hand-tightening the bolts. After all the placement plates 3 are placed, the sealing door of the box 1 is closed, and the box 1 can be started to dry the items inside. At the same time, the main shaft 15 is driven by the servo motor at the bottom of the box 1 to rotate, which drives the placement plate 3 to rotate in a circle, so as to achieve rapid constant temperature drying inside the box 1.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
