Description

Technical Field

[0001] This utility model relates to the field of drying technology for Chinese herbal medicine slices, and in particular to an energy-saving circulating drying device for Chinese herbal medicine slices. Background Technology

[0002] Energy-saving circulating drying equipment for Chinese herbal medicine pieces is used for drying Chinese herbal medicine pieces. One type is a tunnel drying oven, which has the following structure:

[0003] 1. Conveying system: generally includes cycloidal pinwheel reducer, conveyor belt, main drive shaft, driven shaft, etc., responsible for feeding materials such as Chinese herbal medicine pieces into the drying oven in sequence for drying.

[0004] 2. Hot air drying system: The circulating fan promotes the circulation of hot air in the drying chamber, allowing the hot air to contact the material evenly, and the electric heating tube provides heat to heat the air;

[0005] 3. Control system: Controls the operation of each system in the tunnel drying oven, monitors the working status of the equipment, ensures the safe, stable and efficient operation of the equipment, and provides timely alarms and protection in case of abnormalities.

[0006] During the operation of the equipment, Chinese herbal medicine slices are placed on a conveyor belt. As the conveyor belt moves, the Chinese herbal medicine slices gradually enter the drying oven. However, during this process, due to the differences in the shape and volume of the Chinese herbal medicine slices and the randomness of their placement, some materials are prone to accumulating. The material inside the accumulation area cannot fully contact the hot air, resulting in insufficient drying. The material outside the accumulation area, due to prolonged and excessive exposure to hot air, will experience over-drying, leading to damage to the quality of the medicinal materials and loss of effective components. Both situations will reduce the product quality of the Chinese herbal medicine slices. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an energy-saving circulating drying device for Chinese herbal medicine slices. It solves the problem that due to the differences in the shape and volume of Chinese herbal medicine slices and the randomness of their placement, some materials tend to accumulate. The material inside the accumulation area cannot fully contact the hot air, resulting in insufficient drying. On the other hand, the material outside the accumulation area, due to prolonged and excessive exposure to hot air, will over-dry, leading to damage to the quality of the medicinal materials and loss of effective components. Both situations reduce the product quality of Chinese herbal medicine slices.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An energy-saving circulating drying device for traditional Chinese medicine decoction pieces includes a frame, a conveyor belt rotatably connected to the inner side of the frame, a push plate for leveling materials on the outer side of the frame, and an adjustment mechanism for adjusting the height of the push plate on the outer side of the push plate. The adjustment mechanism includes a bracket, a moving hole, an adjustment hole, and a limiting plate. The bracket is located at both ends of the frame. The moving hole is located on the outer side of the frame. The upper end of the push plate is slidably connected to the inside of the moving hole. There are several adjustment holes, all located on the upper end of the push plate. The end of the limiting plate is engaged with the inside of the adjustment hole. A fixing mechanism for restricting the movement of the limiting plate is provided on the upper surface of the bracket. The fixing mechanism includes a mounting frame and a spring. The mounting frame is fixedly mounted on the upper surface of the bracket. The limiting plate is slidably connected to the inner side of the mounting frame. One end of the spring is fixedly connected to the outer side of the mounting frame, and the other end of the spring is fixedly connected to the end of the limiting plate away from the adjustment hole.

[0010] Preferably, the frame has positioning rods at both ends of the corresponding support, and each positioning rod is threaded with a nut. The two ends of the support are slidably connected to the outside of the two positioning rods respectively. The frame has a mounting groove on one side corresponding to each positioning rod, and the end of the positioning rod is engaged in the inside of the mounting groove.

[0011] Preferably, the bracket has a protective cover for shielding each nut on one side, and guide frames are fixedly installed at both ends of the bracket, with the upper end of the protective cover slidably connected to the inner side of the guide frame.

[0012] Preferably, a support shaft for limiting the movement path of the spring is fixedly mounted on the outside of the mounting bracket, the spring is movably sleeved on the outside of the support shaft, and a limiting plate is slidably connected to the outside of the support shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Adjust the distance between the push plate and the conveyor belt according to different Chinese herbal medicine pieces. This is achieved by using a limiting plate that engages with different height adjustment holes to control the height of the push plate. The spring force then secures the push plate to the limiting plate. During the drying process, the push plate flattens the moving material on the conveyor belt, ensuring even distribution of the material and improving drying efficiency and uniformity. This avoids material accumulation that could lead to insufficient or excessive drying in certain areas, thus improving product quality.

[0015] 2. When the adjustment mechanism is not needed, rotate the nut to disconnect the nut from the positioning rod. At this time, you can pull it upward to disconnect the bracket from the positioning rod. The detachable design of the nut and positioning rod makes it easy for the adjustment mechanism to be disassembled and assembled according to actual production needs, thus improving the flexibility of the adjustment mechanism.

[0025] This application provides an energy-saving circulating drying device for Chinese herbal medicine slices, which effectively solves the problem that due to the differences in the shape and volume of Chinese herbal medicine slices and the randomness of their placement, some materials are prone to accumulation. The material inside the accumulation area cannot fully contact the hot air, resulting in insufficient drying, while the material outside the accumulation area is over-dried due to prolonged exposure to hot air, leading to damage to the quality of the medicinal materials and loss of effective components. Both situations reduce the product quality of Chinese herbal medicine slices.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problem that due to the differences in shape and volume of Chinese herbal medicine slices, as well as the randomness of placement, some materials are prone to accumulation. The material inside the accumulation area cannot fully contact the hot air, resulting in insufficient drying. The material outside the accumulation area, due to prolonged and excessive exposure to hot air, will become over-dried, leading to damage to the quality of the medicinal materials and loss of effective components. Both situations reduce the product quality of Chinese herbal medicine slices. The overall approach is as follows:

[0028] To address the problems existing in the prior art, this utility model provides an energy-saving circulating drying device for traditional Chinese medicine decoction pieces, including a frame 1. A push plate 2 for leveling materials is provided on the outside of the frame 1. An adjustment mechanism for adjusting the height of the push plate 2 is provided on the outside of the push plate 2. The adjustment mechanism includes a bracket 3, a moving hole 4, an adjustment hole 5, and a limiting plate 6. The two ends of the bracket 3 are respectively provided at the two ends of the frame 1. The moving hole 4 is opened on the outside of the frame 1. The upper end of the push plate 2 is slidably connected to the inside of the moving hole 4. There are several adjustment holes 5, all of which are opened on the upper end of the push plate 2. The end of the limiting plate 6 is engaged with the inside of the adjustment hole 5.

[0029] The upper surface of the bracket 3 is provided with a fixing mechanism for limiting the movement of the limiting plate 6. The fixing mechanism includes a mounting frame 7 and a spring 8. The mounting frame 7 is fixedly installed on the upper surface of the bracket 3. The limiting plate 6 is slidably connected to the inner side of the mounting frame 7. The limiting plate 6 is L-shaped. One end of the spring 8 is fixedly connected to the outside of the mounting frame 7, and the other end of the spring 8 is fixedly connected to the end of the limiting plate 6 away from the adjustment hole 5.

[0030] The frame 1 is provided with positioning rods 9 at both ends of the bracket 3. The positioning rods 9 are screws, and each positioning rod 9 is threaded with a nut 10. The two ends of the bracket 3 are slidably connected to the outside of the two positioning rods 9 respectively.

[0031] The frame 1 has a mounting groove 11 on one side corresponding to each positioning rod 9, and the end of the positioning rod 9 is engaged inside the mounting groove 11.

[0032] Each side of the bracket 3 corresponding to each nut 10 is provided with a protective cover 12 for shielding. Guide frames 13 are fixedly installed at both ends of the bracket 3, and the upper end of the protective cover 12 is slidably connected to the inner side of the guide frame 13.

[0033] The mounting bracket 7 is externally fixedly mounted with a support shaft 14 for limiting the movement path of the spring 8. The spring 8 is movably sleeved on the outside of the support shaft 14, and the limiting plate 6 is slidably connected to the outside of the support shaft 14.

[0034] Pusher plate 2: During the drying process, pusher plate 2 will flatten the material on conveyor belt 15 to ensure that the material is evenly distributed on conveyor belt 15, so that hot air can evenly exchange heat with the material, improve drying efficiency and uniformity, avoid material accumulation leading to local insufficient drying or over-drying, ensure the consistency of the drying quality of Chinese herbal medicine pieces, and improve product quality.

[0035] Adjustment mechanism: The height of the push plate 2 is controlled by the locking cooperation between the limiting plate 6 and the different height adjustment holes 5. The height of the push plate 2 can be adjusted according to different types of Chinese herbal medicine materials, thereby improving the applicability of the push plate 2.

[0036] Fixing mechanism: The spring force of the spring 8 enables the limit plate 6 to automatically reset and fix the push plate 2, which is easy to operate;

[0037] Positioning rod 9 and nut 10: The detachable design of nut 10 and positioning rod 9 facilitates the disassembly and assembly of the adjustment mechanism according to actual production needs, improving the flexibility of the adjustment mechanism.

[0038] Protective cover 12: It protects the nut 10 and extends its service life;

[0039] Support shaft 14: Ensures that spring 8 remains stable during extension and retraction, without twisting or shifting.

[0040] Working principle:

[0041] The first step is to pull the limiting plate 6 horizontally when the height of the push plate 2 needs to be adjusted so that the end of the limiting plate 6 is disengaged from the adjustment hole 5. The spring 8 is stretched as the limiting plate 6 moves. At this time, the push plate 2 is no longer restricted by the limiting plate 6 and can slide up and down in the moving hole 4. After the push plate 2 is adjusted to a suitable height, the limiting plate 6 is released. Under the elastic force of the spring 8, the end of the limiting plate 6 is re-engaged into the adjustment hole 5 of the corresponding height, thereby fixing the push plate 2 at a new height position to adapt to the need to push the Chinese herbal medicine slices of different thicknesses.

[0042] The second step is to move the protective cover 12 upwards when the adjustment mechanism is not needed, so that the nut 10 is exposed. At this time, rotate the nut 10 to disconnect the nut 10 from the positioning rod 9. Then, pull it upwards to disconnect the bracket 3 from the positioning rod 9.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
