Description

Technical Field

[0001] This invention belongs to the field of medicinal plant processing technology, specifically relating to a production device for digestive aid granule preparations based on Dendrobium officinale powder. Background Technology

[0002] Dendrobium officinale, a traditional and precious medicinal plant, possesses core medicinal properties in Traditional Chinese Medicine (TCM) such as benefiting the stomach and promoting the production of body fluids, nourishing yin and clearing heat. Its active ingredients, including Dendrobium polysaccharides and alkaloids, not only enhance the gastrointestinal mucosal barrier function, promote digestive enzyme secretion, and improve gastrointestinal motility, but also regulate immunity and have antioxidant effects. It is a high-quality raw material for preparing digestive aids. Low-temperature drying is a crucial step in the deep processing of Dendrobium officinale. This process reduces the saturated vapor pressure of the surrounding moisture, using a gentle heat and mass transfer process to gradually migrate and vaporize the free and bound water inside the Dendrobium officinale, minimizing the risk of high-temperature damage to heat-sensitive medicinal components such as polysaccharides and alkaloids, thus preserving its medicinal value and digestive efficacy.

[0003] This low-temperature drying process has extremely stringent requirements for the material's spreading state. During the drying process, Dendrobium officinale must be evenly distributed in a single layer inside the drying device. The key is that only when Dendrobium officinale is evenly spread in a single layer can each Dendrobium officinale fully contact the drying medium, shortening the path of moisture migration and vaporization, ensuring a uniform and stable drying process, and thus achieving consistent drying and meeting the required moisture content. At the same time, it can avoid problems such as local overheating or excessive humidity, protecting the medicinal components from loss and preventing the material from becoming moldy, laying a quality foundation for the subsequent production of digestive aid granules.

[0004] Existing low-temperature drying devices for Dendrobium officinale generally use manual feeding during the material feeding stage. Especially in large-scale production scenarios with large quantities of material, manual feeding cannot achieve precise control over the spreading shape of Dendrobium officinale. Manual feeding relies entirely on the operator's experience and feel. At the same time, when feeding large quantities of Dendrobium officinale, the material is concentrated and easily squeezed and clumps together. It is impossible to spread it into a single layer in real time and evenly, and it is impossible to stably ensure the uniform distribution of Dendrobium officinale inside the device. This easily leads to problems such as local accumulation and uneven thickness. In the accumulated areas, Dendrobium officinale cannot directly contact the drying environment, and the heat transfer and moisture transmission channels are blocked. The internal moisture is difficult to effectively migrate and vaporize and be discharged, directly resulting in uneven drying and excessive local moisture content. Furthermore, the local high humidity environment is prone to causing mold growth in Dendrobium officinale, and prolonged failure to dry completely will further aggravate the loss of effective components, ultimately directly reducing the quality of the finished Dendrobium officinale product. Summary of the Invention

[0005] This invention provides a production device for digestive aid granules based on Dendrobium officinale powder, which solves the technical problem in related technologies where manual feeding of Dendrobium officinale before low-temperature drying cannot achieve uniform material feeding, resulting in local accumulation and uneven thickness of material, which in turn leads to uneven drying, excessive local moisture content, mold growth and loss of effective ingredients, ultimately affecting the efficacy and product quality of Dendrobium officinale digestive aid preparations.

[0006] This invention provides a production device for digestive granule preparations based on Dendrobium officinale powder, including a drying box and a leveling component. A fixed frame is rotatably connected inside the drying box. A motor is fixedly connected to the rear side of the drying box, and the drive end of the motor is fixedly connected to the fixed frame. A top plate is fixedly connected to the upper part of the fixed frame. Multiple drying trays are slidably connected to the inner side of the fixed frame. A lifting mechanism is provided on the fixed frame to push the multiple drying trays to move along the height direction of the fixed frame, thereby opening the distance between two adjacent drying trays. The leveling component includes multiple flat plates, which are driven to move along the length direction of the drying trays. The drying trays have a horizontal state and a vertical state. When the drying tray is in a horizontal position, the spreading plate is located at one end of the drying tray, and there is a gap between the spreading plate and the upper surface of the drying tray. When the drying tray is in a vertical position, the spreading plate is located in the middle of the drying tray and is attached to the side of the drying tray closest to the spreading plate.

[0007] In a preferred embodiment, the mounting frame is provided with a drive assembly for driving the spreader plate to move along the length of the drying tray.

[0008] In a preferred embodiment, the lifting mechanism includes a second motor and a variable pitch screw. The second motor is fixedly mounted on the top plate, and the output end of the second motor is fixedly connected to one end of the variable pitch screw. A lifting block is provided on the side of the drying tray, and a screw hole is opened inside the lifting block. The variable pitch screw passes through the screw hole through the lifting block and forms a threaded engagement with the lifting block through the screw hole.

[0009] In a preferred embodiment, the variable pitch screw is provided with multiple spiral grooves. When the drying tray is in a horizontal state, the pitch of each set of spiral grooves increases sequentially from top to bottom. The variable pitch screw is arranged vertically, and the vertical variable pitch screw passes through the lifting block on each drying tray in sequence.

[0010] In a preferred embodiment, the drive assembly includes multiple toothed plates, which are respectively fixedly connected to the drying tray and the top plate. A motor is fixedly connected to the upper part of the flat plate, and a gear is fixedly connected to the drive end of the motor, which meshes with the toothed plates.

[0011] In a preferred embodiment, a detector is movably connected inside the spreading plate to detect the dryness of the Dendrobium officinale material.

[0012] In a preferred embodiment, the spreading plate includes multiple sliding plates and multiple rotating heads, with the multiple rotating heads movably connected to the corresponding sliding plates. One sliding plate is slidably connected to the top plate, and the remaining multiple sliding plates are slidably connected to the multiple drying trays.

[0013] In a preferred embodiment, the device further includes a blocking element comprising multiple blocks and multiple synchronization plates, which are slidably connected to corresponding drying trays. One block is fixedly connected to a corresponding synchronization plate, and the remaining blocks are slidably connected to corresponding synchronization plates. An elastic sheet is provided between the synchronization plate and the drying tray, and the rotating head abuts against the block.

[0014] In a preferred embodiment, the baffle is T-shaped, and the remaining multiple baffles pass through the corresponding synchronization plates and the corresponding drying trays.

[0015] In a preferred embodiment, a locking element is further included, comprising a wedge block fixedly connected to the inner wall of the drying chamber, a locking rod slidably connected inside the drying tray, a spring being provided between the locking rod and the drying tray, the locking rod being engaged with a stop block, and the wedge block abutting against the locking rod.

[0016] The beneficial effects of this invention are as follows: 1. This invention achieves quantitative loading and uniform spreading of Dendrobium officinale material through the coordinated operation of lifting mechanism and leveling component, effectively avoiding the problems of local accumulation and uneven thickness of material, ensuring the uniformity of material heating and moisture transfer during low-temperature drying, avoiding local excessive moisture content, material mold and loss of effective components, and greatly improving the raw material quality and efficacy stability of Dendrobium officinale digestive aid preparation.

[0017] 2. This invention, through the linkage design of blocking and locking components, not only alleviates the problems of material sloping accumulation causing the spreader to jam and uneven force, but also enables the automatic retraction of the blocking blocks during the spreading stage, ensuring smooth movement of the spreader. It realizes the automation and intelligence of the entire process of feeding, spreading, drying, and testing, improves production efficiency, reduces errors in manual operation and material loss, and is suitable for the large-scale production needs of Dendrobium officinale digestive granule preparations.

Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, a production device for digestive granule preparations based on Dendrobium officinale powder includes a drying box 1 and a leveling component 4. A fixed frame 11 is rotatably connected inside the drying box 1, and a motor 12 is fixedly connected to the outer surface of the drying box 1. The drive end of the motor 12 is fixedly connected to the fixed frame 11. A top plate 14 is fixedly connected to the upper part of the fixed frame 11. Multiple drying trays 13 are slidably connected to the inner side of the fixed frame 11. A lifting mechanism 2 is provided on the fixed frame 11. The lifting mechanism 2 is used to push the drying trays 13 to move along the height direction of the fixed frame 11. The leveling component 4 includes multiple spreading plates 41. The spreading plates 41 are installed on the drying trays 13 and are driven to move along the length direction of the drying trays 13. The drying trays 13 have a horizontal state and a vertical state. When the drying tray 13 is in a horizontal state, the spreading plate 41 is located at one end of the drying tray 13, and there is a gap between the spreading plate 41 and the upper surface of the drying tray 13. When the drying tray 13 is in a vertical position, the spreading plate 41 is located in the middle of the drying tray 13 and is attached to the side of the drying tray 13 near the spreading plate 41.

[0033] It should be added that, such as Figure 2 , Figure 3 and Figure 6As shown, the drying oven 1 is existing technology. The drying oven 1 has a built-in drying unit that can precisely control the drying temperature below 40 degrees Celsius. When performing low-temperature drying on Dendrobium officinale materials, the moisture in the Dendrobium officinale materials can be rapidly evaporated through a low-temperature dehydration process and discharged through a dehumidification system, effectively preserving heat-sensitive active ingredients such as Dendrobium officinale polysaccharides. The drying tray 13 has a U-shaped cross-section. When the drying tray 13 is in a horizontal state, the spreading plate 41 is connected to the drying tray 13 above it. The drying tray 13 is located above and below it. A spreading plate 41 is located at one end of the drying tray 13, with a certain gap between its lower end face and the upper surface of the drying tray 13. Multiple drying trays 13 are arranged equidistantly from top to bottom and are parallel to each other. Adjacent drying trays 13 form accommodating cavities, and the uppermost drying tray 13 also forms an accommodating cavity with the top plate 14. The spreading plate 41 is located within the accommodating cavity and at the side opening of the cavity. When the drying tray 13 is in a vertical position... The spreading plate 41 is located in the middle of the drying tray 13. The side of the spreading plate 41 (which is the lower end face of the spread plate 41 after rotation) is attached to the side of the drying tray 13 (which is the upper surface of the drying tray 13 after rotation). Multiple drying trays 13 are arranged equidistantly from left to right. At this time, the spreading plate 41 is located in the middle of the receiving cavity, and the spreading plate 41 divides the receiving cavity into a first chamber 132 and a second chamber 133. The first chamber 132 is located above the spreading plate 41, and the second chamber 133 is located below the first chamber 132. Below the spreading plate 41, the spreading plate 41 seals the bottom opening of the first chamber 132. At this time, only the top opening of the first chamber 132 is open, and the top opening of the first chamber 132 corresponds to the feed inlet on the drying box 1. In this embodiment, the fixed frame 11 is provided with a drive assembly 42. The drive assembly 42 is used to drive the spreading plate 41 to move along the length direction of the drying tray 13. The drive assembly 42 can be a linear drive mechanism such as a cylinder or an electric push rod 44. This is the prior art and will not be described in detail. Specifically, such as Figure 3 and Figure 4 As shown, in this embodiment, the lifting mechanism 2 includes a second motor 21 and a variable pitch screw 22. The second motor 21 is fixedly installed on the top plate 14. The output end of the second motor 21 is fixedly connected to one end of the variable pitch screw 22. The side of the drying tray 13 is provided with a lifting block 23. The inside of the lifting block 23 is provided with a screw hole 231. The variable pitch screw 22 passes through the lifting block 23 through the screw hole 231 and forms a threaded engagement with the lifting block 23 through the screw hole 231.

[0034] It is necessary to add that, such as Figure 3 and Figure 4As shown, the variable pitch screw 22 has multiple spiral grooves 221. When the drying tray 13 is in a horizontal state, the pitch of each set of spiral grooves 221 increases sequentially from top to bottom. The variable pitch screw 22 is arranged vertically. Since each drying tray 13 is provided with a lifting block 23, the vertical variable pitch screw passes through the lifting block 23 on each drying tray 13 sequentially. The variable pitch screw 22 is existing technology and will not be described in detail. Figure 3 and Figure 4 As shown, the multi-segment spiral grooves 221 are arranged sequentially along the length direction of the variable pitch screw 22. For example, the ratio of the pitch of the multi-segment spiral grooves 221 from top to bottom is 1:2:3:4, and the ratio of the length of the multi-segment spiral grooves 221 from top to bottom is 1:2:3:4. In other embodiments, the pitch can be set to other ratios. It is only necessary that the adjacent drying trays 13 can open to each other and that the distance between the spreading plate 41 and the corresponding drying tray 13 can be formed. By setting the ratio of the pitch to the length of the multi-segment spiral grooves 221, multiple drying trays 13 can move at the same relative speed while moving, that is, multiple drying trays 13 can maintain equidistant movement. It should be noted that, as Figure 3 and Figure 4 As shown, motor 21 is fixedly connected to the top plate 14. The drive end of motor 21 passes through the top plate 14 and is fixedly connected to the pitch screw 22. The end of the pitch screw 22 facing away from motor 21 is rotatably connected to the fixed frame 11. It should be noted that, as Figure 2 and Figure 3 As shown, the inner side of the fixed frame 11 is provided with multiple sliding grooves 111. The groove direction of the sliding grooves 111 is consistent with the height direction of the sliding grooves 111. Multiple lifting blocks 131 are fixedly connected to the outer wall of the drying tray 13. The lifting blocks 131 are located inside the sliding grooves 111 and form a sliding guide cooperation with the sliding grooves 111. That is, the lifting blocks 131 are slidably connected to the fixed frame 11 through the sliding grooves 111, that is, the drying tray 13 is slidably connected to the fixed frame 11. In actual use, the drying tray 13 is initially in a horizontal state. When loading Dendrobium officinale material that has not been dried at low temperature, the drive component 42 first drives the spreading plate 41 to move to the middle of the drying tray 13. Then, the motor 12 is started. The start of the motor 12 can drive the fixed frame 11 to rotate 90 degrees. At this time, multiple drying trays 13 rotate from a horizontal state to a vertical state, so that one side of the fixed frame 11 faces the feed inlet of the drying box 1. Dendrobium officinale material is fed into the first chamber 132 above the spreading plate 41 through the feed inlet. At this time, the Dendrobium officinale material will accumulate in the first chamber 132 after entering it. When the Dendrobium officinale material fills the first chamber 132, the feeding stops. Then, motor 12 is started, causing the drying tray 13 to rotate from a vertical position to a horizontal position. During the resetting process, the spreading plate 41, driven by the drive assembly 42, gradually moves towards the side closer to the second chamber 133. The movement of the spreading plate 41 causes the internal volume of the first chamber 132 to increase. At this time, the Dendrobium officinale material will move downward under the action of gravity. When the spreading plate 41 moves to the lower edge of the drying tray 13, the drying tray 13 rotates back to a horizontal position, and the internal volume of the first chamber 132 is at its maximum. At this time, the Dendrobium officinale material can be distributed throughout the entire space of the first chamber 132, and is subjected to... Due to gravity, the Dendrobium officinale material is distributed in a sloping pattern within the first chamber 132, with the largest accumulation at the end of the first chamber 132 closest to the spreading plate 41. At this point, motor 21 is activated. Motor 21, through the cooperation of the variable-pitch screw 22 and the lifting block 23, drives multiple drying trays 13 to move simultaneously along the height of the fixed frame 11, moving them further apart. The distance between adjacent drying trays 13, as well as the distance between the top plate 14 and the drying trays 13 below it, gradually increases. When the distance between the spreading plate 41 and the drying trays 13 reaches the set thickness of the Dendrobium officinale material, motor 21 stops. The rotation then activates the drive assembly 42, causing the spreading plate 41 to move from one end of the drying tray 13 to the other. During this movement, the spreading plate 41 pushes the Dendrobium officinale material above a set thickness towards the other end. When the Dendrobium officinale material thickness falls below a set value, Dendrobium officinale material above the set value on one side of the spreading plate 41 fills the missing portion. When the spreading plate 41 moves to the other end of the drying tray 13, the Dendrobium officinale material on the drying tray 13 is evenly distributed under the pushing action of the spreading plate 41. Since the volume of the drying tray 13 is constant, and the initial position of the spreading plate 41 is fixed... This makes the volume of the first chamber 132 fixed, thus determining the amount of Dendrobium officinale material to be added. This limits the amount of Dendrobium officinale material added, which in turn limits the amount of Dendrobium officinale material on the drying tray 13, i.e., achieving quantitative processing of Dendrobium officinale material. Therefore, only a fixed amount of Dendrobium officinale material can be loaded when loading Dendrobium officinale material. After the fixed frame 11 rotates to the horizontal position, under the push of the spreading plate 41, the Dendrobium officinale material can be evenly distributed on the upper part of the drying tray 13, thereby achieving the function of evenly spreading the Dendrobium officinale material.

[0035] In another embodiment of the invention, further, as Figure 6 and Figure 7 As shown, the drive assembly 42 includes multiple toothed plates 423, which are fixedly connected to the drying tray 13 and the top plate 14 respectively. A motor 421 is fixedly connected to the upper part of the flat plate 41, and a gear 422 is fixedly connected to the drive end of the motor 421. The gear 422 meshes with the toothed plates 423. It should be noted that, as Figure 3, Figure 6 and Figure 7 As shown, the multiple toothed plates 423 are divided into two groups. One group has one toothed plate 423, and the number of toothed plates 423 in the other group is the same as the number of multiple drying trays 13 in the other group. One toothed plate 423 in one group is fixedly connected to the lower part of the top plate 14, and the multiple toothed plates 423 in the other group are respectively fixedly connected to the lower part of the multiple drying trays 13 in the other group. It should be noted that, as Figure 2 and Figure 6 As shown, the multiple spreading plates 41 are divided into two groups. One group has one spreading plate 41, and the number of spreading plates 41 in the other group is the same as the number of multiple drying trays 13 in the other group. Two limiting blocks 424 are fixedly connected to the upper part of the spreading plate 41. The two limiting blocks 424 are symmetrically distributed on the upper part of the spreading plate 41. Two limiting grooves 425 are opened on the lower part of the top plate 14 and the lower part of the multiple drying trays 13 in the other group. The limiting blocks 424 are located inside the limiting grooves 425 and form a sliding guide engagement with the limiting grooves 425. That is, one spreading plate 41 in one group is slidably connected to the top plate 14, and the multiple spreading plates 41 in the other group are slidably connected to the lower part of the multiple drying trays 13 in the other group. Through the guiding engagement of the limiting blocks 424 and the limiting grooves 425, the sliding of the spreading plate 41 can be restricted to move along the length direction of the drying tray 13. During the process of switching the drying tray 13 from a vertical to a horizontal state, motor 3 421 starts and drives gear 422 to rotate. Gear 422, through meshing with toothed plate 423, pushes motor 3 421 in the opposite direction, thereby pushing the spreading plate 41 to move along the length of the drying tray 13. When the spreading plate 41 moves away from the first chamber 132, motor 3 421 shuts off. At this time, the volume of the first chamber 132 is at its maximum, and the Dendrobium officinale material is distributed throughout the entire first chamber 132. In subsequent... When the spreading plate 41 flattens the Dendrobium officinale material inside the first chamber 132, it is necessary to control the motor 3 421 to rotate in the opposite direction, so that the gear 422 pushes the spreading plate 41 from one end of the drying tray 13 to the other end. During the movement, the spreading plate 41 can push the unevenly distributed Dendrobium officinale material in the first chamber 132 to be evenly distributed on the upper surface of the drying tray 13. Thus, the spreading plate 41 can move linearly along the drying tray 13 through the cooperation of the motor 3 421, the gear 422 and the toothed plate 423.

[0036] In another embodiment of the invention, further, as Figure 7 and Figure 10 As shown, a detector 43 is movably connected inside the spreading plate 41. The detector 43 is used to detect the dryness of the Dendrobium officinale material.

[0037] It should be noted that, as Figure 9 and Figure 10 As shown, a second sliding groove 4111 is provided inside the paving plate 41. The groove direction of the second sliding groove 4111 is consistent with the height direction of the paving plate 41. The length of the second sliding groove 4111 is less than the length of the paving plate 41. The detector 43 is located inside the second sliding groove 4111 and forms a sliding guide engagement with the second sliding groove 4111. That is, the detector 43 is slidably connected to the paving plate 41 through the second sliding groove 4111. An electric push rod 44 is provided inside the paving plate 41. The driving end of the electric push rod 44 extends into the interior of the second sliding groove 4111 and is fixedly connected to the detector 43. In this embodiment, detector 43 is an online detection device based on the principle of near-infrared spectroscopy. It uses long-wave near-infrared light to irradiate the Dendrobium officinale material on the drying tray 13 to form a spectrum. Detector 43 collects the spectral signal and performs noise reduction and feature extraction processing on the signal using a preprocessing fusion algorithm. It quickly identifies the moisture content, distribution and content of core effective components such as Dendrobium officinale polysaccharides in the Dendrobium officinale material, and provides real-time feedback on the dryness and distribution uniformity of the Dendrobium officinale material. This detector 43 is existing technology and will not be described in detail.

[0038] After the Dendrobium officinale material is spread evenly on the spreading plate 41, the spreading plate 41 is located on one side of the drying tray 13. After the device dries the Dendrobium officinale material, it is necessary to detect the moisture content of the dried Dendrobium officinale material. At this time, the electric push rod 44 needs to be activated to push the detector 43 downward. The detector 43 extends out from the inside of the spreading plate 41. At this time, the drive component 42 is activated to drive the spreading plate 41 to move. The spreading plate 41 moves from one end of the drying tray 13 to the other end. During the movement of the spreading plate 41, the detector 43 can detect the Dendrobium officinale material. The movement of the spreading plate 41 can realize the scanning detection of the Dendrobium officinale material.

[0039] Since detector 43 detects Dendrobium officinale material optically, its lens must not be contaminated. Contamination can cause light scattering and deflection, which would contaminate the detection data. To further protect detector 43 in other embodiments of this invention, such as... Figure 8 , Figure 9 and Figure 10 As shown, the spreading plate 41 includes a sliding plate 411 and a rotating head 412. The rotating head 412 is movably connected to the sliding plate 411. One of the multiple sliding plates 411 is slidably connected to the top plate 14, and the other multiple sliding plates 411 are slidably connected to the multiple drying trays 13 respectively. The number of the other multiple sliding plates 411 is the same as the number of the multiple drying trays 13. It is necessary to add that, such as Figure 8 , Figure 9 and Figure 10As shown, the sliding plate 411 is the flat plate 41 in the previous embodiment. In this embodiment, the detector 43 is slidably connected to the sliding plate 411, the electric push rod 44 is fixedly connected to the sliding plate 411, and two limiting blocks 424 are symmetrically distributed and fixedly connected to the upper part of the sliding plate 411. Fixed rods 413 are fixedly connected to both ends of the sliding plate 411, and connecting rods 431 are fixedly connected to both ends of the detector 43. The end of the connecting rod 431 away from the detector 43 is rotatably connected to the push plate 414. A passive groove 4141 is provided in the middle of the push plate 414. The groove direction of the passive groove 4141 is consistent with the length direction of the push plate 414. The fixed rod 413 is located inside the passive groove 4141 and forms a sliding guide cooperation with the passive groove 4141. That is, the fixed rod 413 is slidably connected to the push plate 414 through the passive groove 4141, and the end of the push plate 414 away from the connecting rod 431 is fixedly connected to the rotating head 412. It is necessary to add that, such as Figure 8 , Figure 9 and Figure 10 As shown, the rotating head 412 has a closed state and an open state. The closed state is the initial state of the rotating head 412. When the rotating head 412 is in the closed state, the rotating head 412 is located at the lower part of the sliding plate 411, the fixed rod 413 is located inside the passive groove 4141 on the side close to the rotating head 412, and the detector 43 is completely retracted inside the second groove 4111. When the rotating head 412 is in the open state, the rotating head 412 is located on the side of the sliding plate 411, the fixed rod 413 is located inside the passive groove 4141 on the side away from the rotating head 412, and the detector 43 extends out of the second groove 4111.

[0040] When the drying tray 13 is in a horizontal position, the lifting mechanism 2 drives multiple drying trays 13 to slide, increasing the distance between the multiple drying trays 13 and the distance between the top plate 14 and the uppermost drying tray 13. When the Dendrobium officinale material on the upper surface of the drying tray 13 accumulates on the side of the sliding plate 411 and rotating head 412 near the first chamber 132, the rotating head 412 is in a closed state. When the sliding plate 411 and rotating head 412 move from one end of the drying tray 13 to the other under the drive of the drive assembly 42, the rotating head 412 can completely seal the lower end of the sliding plate 411, preventing the Dendrobium officinale material from contaminating the detector 43. When the sliding plate 411 and rotating head 412 flatten the Dendrobium officinale material, the sliding plate 411 and rotating head 412 are pushed by the drive assembly 42 to move along the upper surface of the drying tray 13. During the movement of the sliding plate 411 and rotating head 412, the sliding plate... The movement of 411 and rotating head 412 can flatten the Dendrobium officinale material, and then the device begins to dry the Dendrobium officinale material at low temperature. During the drying process, rotating head 412 remains closed. After the Dendrobium officinale material is dried, the electric push rod 44 is activated to drive detector 43 to move downward. At this time, rotating head 412 switches from closed to open. Then, the drive mechanism is activated to drive sliding plate 411 and rotating head 412 from one end of drying tray 13 to the other end. During the movement of sliding plate 411, detector 43 can scan the dried Dendrobium officinale material as sliding plate 411 moves. When sliding plate 411 moves to the end of drying tray 13, the scanning of Dendrobium officinale material is completed. At this time, the electric push rod 44 can be controlled to retract detector 43, switching from open to closed, thereby realizing the protection function of detector 43.

[0041] In the above embodiments, such as Figure 5 and Figure 6As shown, due to the smooth inner wall of the drying tray 13, during the process of the fixing frame 11 rotating from the vertical position to the horizontal position, the Dendrobium officinale material in the drying tray 13 will continue to accumulate downwards under the action of gravity. This results in the Dendrobium officinale material accumulating the most on the side of the first chamber 132 closest to the spreading plate 41 when the drying tray 13 is in the horizontal position. The distribution of Dendrobium officinale material in the first chamber 132 is sloping. This causes the resistance at the material accumulation area to be much greater than that in the area with less accumulation when the spreading plate 41 moves to spread the Dendrobium officinale material. This easily leads to the problem of slow movement and uneven force on the spreading plate 41. This not only affects the spreading efficiency, but may also cause the Dendrobium officinale material to be pushed to the edge of the drying tray 13 and spill due to excessive local thrust. At the same time, the sloping distribution of material will make the spreading process more difficult. During the leveling process of plate 41, some materials are excessively crushed, damaging the shape of Dendrobium officinale material. Furthermore, the leveling time varies greatly between thick and thin areas, making it difficult to achieve rapid and uniform spreading of the material at the set thickness. In the subsequent drying process, the uneven initial distribution of the material will also result in inconsistent drying levels. Therefore, in order to solve this technical problem, the digestive granule preparation production device also includes a blocking component 5. The blocking component 5 includes multiple blocks 51 and a synchronization plate 52. The multiple blocks 51 and the synchronization plate 52 are slidably connected to the drying tray 13. One of the multiple blocks 51 is fixedly connected to the synchronization plate 52, while the remaining blocks 51 are slidably connected to the synchronization plate 52. An elastic sheet 53 is provided between the synchronization plate 52 and the drying tray 13, and the rotating head 412 abuts against the block 51.

[0042] It should be noted that, as Figure 5 and Figure 6 As shown, the length direction of the stop block 51 is consistent with the width direction of the synchronization plate 52, the length direction of the synchronization plate 52 is consistent with the length direction of the drying tray 13, and the length direction of the elastic sheet 53 is consistent with the length direction of the stop block 51. It should be noted that, as Figure 5 and Figure 6 As shown, multiple blocks 51 are divided into two groups. One group has one block 51, and the other group has several blocks 51. One block 51 is fixedly connected to one end of the synchronization plate 52. That is, when the drying tray 13 is in a horizontal state, the block 51 is located directly below the spreading plate 41. The elastic sheet 53 is fixedly connected to the lower part of the block 51. The drying tray 13 has a sliding groove 3 54 inside. The synchronization plate 52 is located inside the sliding groove 3 54 and forms a sliding guide engagement with the sliding groove 3 54. That is, the synchronization plate 52 is slidably connected to the drying tray 13 through the sliding groove 3 54. It should be noted that, as Figure 6 As shown, the shape of the baffle 51 is T-shaped, and another set of several baffles 51 penetrate the synchronization plate 52. All the baffles 51 penetrate the drying tray 13. It should be noted that, as Figure 5 and Figure 6 As shown, the stop block 51 has two states: an extended state and a retracted state. When the stop block 51 is in the extended state, both the stop block 51 and the synchronization plate 52 are located inside the slide groove 3 54, and the elastic sheet 53 is in a natural state. When the stop block 51 is in the retracted state, the stop block 51 is retracted into the slide groove 3 54, the upper end face of the stop block 51 is flush with the upper surface of the drying tray 13, and the elastic sheet 53 is in a compressed state.

[0043] After the first chamber 132 is filled with Dendrobium officinale material, the drying tray 13 slowly switches from a vertical to a horizontal state. The sliding plate 411 is driven by the drive assembly 42 to move along the drying tray 13 away from the first chamber 132, which causes the internal space of the first chamber 132 to gradually increase. When the sliding plate 411 moves, it will pass through multiple blocks 51. When the sliding plate 411 passes a block 51, the rotating head 412 will push the block 51 from the extended state to the retracted state. When the rotating head 412 passes the current block 51, the block 51 loses pressure and switches from the retracted state to the extended state under the action of the elastic sheet 53. At this time, as the sliding plate 411 moves downward, blocks 51 will continuously block the sliding plate 411 and the Dendrobium officinale material. At this time, the surface of the drying tray 13 will not be in a smooth and flat state, but in a discontinuous state. The blocks 51 can block one The quantitative distribution of Dendrobium officinale material reduces the significant difference in material distribution between adjacent baffles 51, effectively mitigating the problem of sloping accumulation of material on the drying tray 13. This allows the material to be distributed in segments when the fixed frame 11 rotates to a horizontal position, greatly reducing the resistance difference between different areas when the sliding plate 411 is leveled, and preventing jamming or uneven force distribution. Simultaneously, it prevents the material from being pushed and spilled due to excessive local thrust, reducing material loss and preventing excessive crushing that could damage the particle shape. This ensures that the sliding plate 411 quickly completes the spreading of the material within its set stroke, achieving a uniform distribution of the material to a set thickness on the drying tray 13. This lays a uniform foundation for the subsequent low-temperature drying process, guaranteeing the consistent quality of the dried Dendrobium officinale material.

[0044] In the above embodiments, such as Figure 11 and Figure 12As shown, when the sliding plate 411 flattens the Dendrobium officinale material, the lower end of the rotating head 412 is a certain distance from the surface of the drying tray 13. This distance is the thickness of the Dendrobium officinale material. During the movement of the sliding plate 411, when the stop block 51 is pushed downward by the rotating head 412, there will always be a height equal to the thickness of the Dendrobium officinale material. The stop block 51 cannot be completely pressed into the retracted state by the rotating head 412, and part of the stop block 51 will always be in the extended state. When the sliding plate 411 moves and pushes the Dendrobium officinale material, the Dendrobium officinale material will get stuck on the side of the stop block 51. In other words, the extended stop 51 will act as a block, which will continuously hinder the normal movement of the sliding plate 411, causing the sliding plate 411 to move with increased resistance and run poorly. Therefore, in order to solve this technical problem, the digestive granule preparation production device also includes a locking component 3. The locking component 3 includes a wedge block 31, which is fixedly connected to the inner wall of the drying chamber 1. A locking rod 33 is slidably connected inside the drying tray 13. A spring 32 is provided between the locking rod 33 and the drying tray 13. The locking rod 33 is engaged with the stop 51, and the wedge block 31 abuts against the locking rod 33.

[0045] It should be noted that, as Figure 12 As shown, the wedge block 31 is trapezoidal and is vertically arranged on the inner wall of the drying chamber 1. The thickness of the wedge block 31 is less than the distance between the fixing frame 11 and the drying chamber 1. The wedge block 31 and the locking rod 33 abut against each other at the ends away from the spring 32. It should be noted that, as Figure 11 and Figure 12 As shown, one of the blocks 51, which is a single block, has a locking groove 511 on the side near the locking rod 33. The locking rod 33 is located inside the locking groove 511 and forms a locking engagement with the locking groove 511. That is, the locking rod 33 is locked to one of the blocks 51 through the locking groove 511. It should be noted that, as Figure 11 and Figure 12 As shown, a plurality of springs 32 are fixedly connected to the middle of the locking rod 33, and one end of the spring 32 away from one of the stops 51 is fixedly connected to the drying tray 13. It should be noted that, as Figure 12 As shown, the locking lever 33 has a locked state and an unlocked state. When the locking lever 33 is in the locked state, one end of the locking lever 33 abuts against the wedge block 31, and the other end is engaged inside the engagement groove 511, and the spring 32 is in the stretched state. When the locking lever 33 is in the unlocked state, the spring 32 is in the unstressed state.

[0046] During the process of switching the drying tray 13 from a vertical to a horizontal state, the sliding plate 411 moves to the edge of the drying tray 13 under the drive of the drive assembly 42, where the first chamber 132 has the largest volume. At this time, the rotating head 412 can press against the upper part of the stop block 51 at the outermost edge. At this time, the stop block 51 can be lowered by the synchronous plate 52. Simultaneously, the locking rod 33 abuts against the inclined surface of the wedge block 31 during the movement. As the drying tray 13 rotates, the inclined surface of the wedge block 31 can push the locking rod 33 to slide into the inside of the locking groove 511. Thus, the wedge block 31 can push multiple locking rods 33 to slide into the corresponding locking grooves 511. At this time, the state of the stop block 51 is locked. Since this stop block 51 is fixedly connected to the synchronous plate 52, the synchronous plate 52 can push the remaining multiple stops 51 together to the edge. As the drying tray moves downward, the multiple blocks 51 on the upper part of the drying tray 13 switch from the extended state to the retracted state, and the upper surface of the drying tray 13 is reconnected into a continuous segment. Then, the sliding plate 411 begins to move and flatten the Dendrobium officinale material under the drive of the drive component 42. At this time, there are no blocks 51 obstructing the surface of the drying tray 13, and it is in a smooth and continuous flat state. The sliding plate 411 can move smoothly along the surface of the drying tray 13 to flatten the small pile of Dendrobium officinale material on the upper surface of the drying tray 13. The force is uniform and there is no jamming throughout the process, which greatly improves the flattening efficiency. In other embodiments, a linear drive mechanism such as a cylinder or hydraulic rod can be used to drive the synchronous plate 52 to move. One end of the linear drive mechanism is fixedly connected to the drying tray 13, and the drive end is fixedly connected to the synchronous plate 52. The synchronous plate 52 is directly driven to move through the linear drive mechanism to drive multiple blocks 51 to move simultaneously. After the Dendrobium officinale material is dried and tested, motor 12 starts and drives the fixed frame 11 to rotate from a horizontal position to an inclined position. At this time, the first chamber 132 is oriented at the lower part of the horizontal direction, that is, the drying tray 13 is in an inclined state. At this time, the Dendrobium officinale material will slide along the upper part of the drying tray 13 under the influence of gravity and slide out of the first chamber 132. In actual use, a collection device can be set in the inclined direction of the drying tray 13 so that the Dendrobium officinale material sliding out of the first chamber 132 can fall into the collection device to realize the feeding and collection of Dendrobium officinale material. After the feeding and collection of Dendrobium officinale material is completed, the motor 12 is driven to rotate in the opposite direction so that the drying tray 13 returns to the vertical state. During this process, all components are reset to the initial state, and the device can be put into production again.

[0047] The overall working principle of this invention: In actual use, the drying tray 13 is initially in a horizontal state. When loading Dendrobium officinale material that has not been dried at low temperature, the drive component 42 first drives the spreading plate 41 to move to the middle of the drying tray 13. Then, the motor 12 is started. The start of the motor 12 can drive the fixed frame 11 to rotate 90 degrees. At this time, multiple drying trays 13 rotate from a horizontal state to a vertical state, so that one side of the fixed frame 11 faces the feed inlet of the drying box 1. Dendrobium officinale material is fed into the first chamber 132 above the spreading plate 41 through the feed inlet. At this time, the Dendrobium officinale material will accumulate in the first chamber 132 after entering it. When the Dendrobium officinale material fills the first chamber 132, the feeding stops. Then, motor 12 is started, causing the drying tray 13 to rotate from a vertical position to a horizontal position. During the resetting process, the spreading plate 41, driven by the drive assembly 42, gradually moves towards the side closer to the second chamber 133. The movement of the spreading plate 41 causes the internal volume of the first chamber 132 to increase. At this time, the Dendrobium officinale material will move downward under the action of gravity. When the spreading plate 41 moves to the lower edge of the drying tray 13, the drying tray 13 rotates back to a horizontal position, and the internal volume of the first chamber 132 is at its maximum. At this time, the Dendrobium officinale material can be distributed throughout the entire space of the first chamber 132, and is subjected to... Due to gravity, the Dendrobium officinale material is distributed in a sloping pattern within the first chamber 132, with the largest accumulation at the end of the first chamber 132 closest to the spreading plate 41. At this point, motor 21 is activated. Motor 21, through the cooperation of the variable-pitch screw 22 and the lifting block 23, drives multiple drying trays 13 to move simultaneously along the height of the fixed frame 11, moving them further apart. The distance between adjacent drying trays 13, as well as the distance between the top plate 14 and the drying trays 13 below it, gradually increases. When the distance between the spreading plate 41 and the drying trays 13 reaches the set thickness of the Dendrobium officinale material, motor 21 stops. The rotation then activates the drive assembly 42, causing the spreading plate 41 to move from one end of the drying tray 13 to the other. During this movement, the spreading plate 41 pushes the Dendrobium officinale material above a set thickness towards the other end. When the Dendrobium officinale material thickness falls below a set value, Dendrobium officinale material above the set value on one side of the spreading plate 41 fills the missing portion. When the spreading plate 41 moves to the other end of the drying tray 13, the Dendrobium officinale material on the drying tray 13 is evenly distributed under the pushing action of the spreading plate 41. Since the volume of the drying tray 13 is constant, and the initial position of the spreading plate 41 is fixed... This makes the volume of the first chamber 132 fixed, and thus the volume of the first chamber 132 determines the amount of Dendrobium officinale material to be put in, thereby limiting the amount of Dendrobium officinale material to be put in, which in turn limits the amount of Dendrobium officinale material on the drying tray 13, that is, achieving quantitative processing of Dendrobium officinale material. Thus, only a fixed amount of Dendrobium officinale material can be loaded when loading Dendrobium officinale material. After the fixed frame 11 rotates to the horizontal position, under the push of the spreading plate 41, the Dendrobium officinale material can be evenly distributed on the upper part of the drying tray 13, thereby achieving the function of evenly spreading the Dendrobium officinale material. After the Dendrobium officinale material is spread out on the spreading plate 41, the spreading plate 41 is located on one side of the drying tray 13. After the device dries the Dendrobium officinale material, it is necessary to detect the moisture content of the dried Dendrobium officinale material. At this time, the electric push rod 44 is activated to push the detector 43 to move downward. The detector 43 extends out from the inside of the spreading plate 41. At this time, the drive component 42 is activated to drive the spreading plate 41 to move. The spreading plate 41 moves from one end of the drying tray 13 to the other end. During the movement of the spreading plate 41, the detector 43 can detect the Dendrobium officinale material. The movement of the spreading plate 41 can realize the scanning detection of the Dendrobium officinale material. When the drying tray 13 is in a horizontal position, the lifting mechanism 2 drives multiple drying trays 13 to slide, increasing the distance between the multiple drying trays 13 and the distance between the top plate 14 and the uppermost drying tray 13. When the Dendrobium officinale material on the upper surface of the drying tray 13 accumulates on the side of the sliding plate 411 and rotating head 412 near the first chamber 132, the rotating head 412 is in a closed state. When the sliding plate 411 and rotating head 412 move from one end of the drying tray 13 to the other under the drive of the drive assembly 42, the rotating head 412 can completely seal the lower end of the sliding plate 411, preventing the Dendrobium officinale material from contaminating the detector 43. When the sliding plate 411 and rotating head 412 flatten the Dendrobium officinale material, the sliding plate 411 and rotating head 412 are pushed by the drive assembly 42 to move along the upper surface of the drying tray 13. During the movement of the sliding plate 411 and rotating head 412, the sliding plate... The movement of 411 and rotating head 412 can flatten the Dendrobium officinale material, and then the device begins to dry the Dendrobium officinale material at low temperature. During the drying process, rotating head 412 remains closed. After the Dendrobium officinale material is dried, the electric push rod 44 is activated to drive the detector 43 to move downward. At this time, rotating head 412 switches from closed to open. Then, the drive mechanism is activated to drive sliding plate 411 and rotating head 412 from one end of drying tray 13 to the other end. During the movement of sliding plate 411, detector 43 can scan the dried Dendrobium officinale material as sliding plate 411 moves. When sliding plate 411 moves to the end of drying tray 13, the scanning of Dendrobium officinale material is completed. At this time, the electric push rod 44 can be controlled to retract detector 43, switching from open to closed. This can realize the protection function of detector 43. After the first chamber 132 is filled with Dendrobium officinale material, the drying tray 13 slowly switches from a vertical to a horizontal state. The sliding plate 411 is driven by the drive assembly 42 to move along the drying tray 13 away from the first chamber 132, which causes the internal space of the first chamber 132 to gradually increase. When the sliding plate 411 moves, it will pass through multiple blocks 51. When the sliding plate 411 passes a block 51, the rotating head 412 will push the block 51 from the extended state to the retracted state. When the rotating head 412 passes the current block 51, the block 51 loses pressure and switches from the retracted state to the extended state under the action of the elastic sheet 53. At this time, as the sliding plate 411 moves downward, blocks 51 will continuously block the sliding plate 411 and the Dendrobium officinale material. At this time, the surface of the drying tray 13 will not be in a smooth and flat state, but in a discontinuous state. The blocks 51 can block one The quantitative distribution of Dendrobium officinale material reduces the significant difference in material distribution between adjacent baffles 51, effectively mitigating the problem of sloping accumulation of material on the drying tray 13. This allows the material to be distributed in segments when the fixed frame 11 rotates to a horizontal position, greatly reducing the resistance difference between different areas when the sliding plate 411 is leveled, preventing jamming or uneven force distribution. Simultaneously, it prevents the material from being pushed and spilled due to excessive local thrust, reducing material loss and avoiding excessive crushing that could damage the particle shape. This ensures the sliding plate 411 quickly completes the spreading of the material within its set stroke, achieving a uniform distribution of the set thickness on the drying tray 13. This lays a uniform foundation for the subsequent low-temperature drying process, guaranteeing consistent quality of the dried Dendrobium officinale material. During the process of switching the drying tray 13 from a vertical to a horizontal state, the sliding plate 411 moves to the edge of the drying tray 13 under the drive of the drive assembly 42, where the first chamber 132 has the largest volume. At this time, the rotating head 412 can press against the upper part of the stop block 51 at the outermost edge. At this time, the stop block 51 can be lowered by the synchronous plate 52. Simultaneously, the locking rod 33 abuts against the inclined surface of the wedge block 31 during the movement. As the drying tray 13 rotates, the inclined surface of the wedge block 31 can push the locking rod 33 to slide into the inside of the locking groove 511. Thus, the wedge block 31 can push multiple locking rods 33 to slide into the corresponding locking grooves 511. At this time, the state of the stop block 51 is locked. Since this stop block 51 is fixedly connected to the synchronous plate 52, the synchronous plate 52 can push the remaining multiple stops 51 together to the edge. As the drying tray moves downward, the multiple blocks 51 on the upper part of the drying tray 13 switch from the extended state to the retracted state, and the upper surface of the drying tray 13 is reconnected into a continuous segment. Then, the sliding plate 411 begins to move and flatten the Dendrobium officinale material under the drive of the drive component 42. At this time, there are no blocks 51 obstructing the surface of the drying tray 13, and it is in a smooth and continuous flat state. The sliding plate 411 can move smoothly along the surface of the drying tray 13 to flatten the small pile of Dendrobium officinale material on the upper surface of the drying tray 13. The force is uniform and there is no jamming throughout the process, which greatly improves the flattening efficiency. In other embodiments, a linear drive mechanism such as a cylinder or hydraulic rod can be used to drive the synchronous plate 52 to move. One end of the linear drive mechanism is fixedly connected to the drying tray 13, and the drive end is fixedly connected to the synchronous plate 52. The synchronous plate 52 is directly driven to move through the linear drive mechanism to drive multiple blocks 51 to move simultaneously. After the Dendrobium officinale material is dried and tested, motor 12 starts and drives the fixed frame 11 to rotate from a horizontal position to an inclined position. At this time, the first chamber 132 is oriented at the lower part of the horizontal direction, that is, the drying tray 13 is in an inclined state. At this time, the Dendrobium officinale material will slide along the upper part of the drying tray 13 under the influence of gravity and slide out of the first chamber 132. In actual use, a collection device can be set in the inclined direction of the drying tray 13 so that the Dendrobium officinale material sliding out of the first chamber 132 can fall into the collection device to realize the feeding and collection of Dendrobium officinale material. After the feeding and collection of Dendrobium officinale material is completed, the motor 12 is driven to rotate in the opposite direction so that the drying tray 13 returns to the vertical state. During this process, all components are reset to the initial state, and the device can be put into production again.

[0048] In another embodiment of the present invention, a method for producing a digestive aid granule formulation based on Dendrobium officinale powder is disclosed, comprising the following steps: Step 1: Take the following ingredients by weight: 10-15 parts Dendrobium officinale powder, 10-15 parts hawthorn powder, 3-5 parts dried tangerine peel powder, and 5-10 parts honey powder. Step 2: Mix Dendrobium officinale powder, hawthorn powder, dried tangerine peel powder, and honey powder evenly to form a mixture; Step 3: Add moisture to the mixture and stir to prepare a wet mixture; Step 4: Form the wet mixture into wet granules; Step 5: Dry the wet granules at low temperature to produce dry granules; Step Six: Dry granules are shaped into finished granules; Step 7: Pack the finished product into bags.

[0049] It should be noted that all powder raw materials are 80-100 mesh fine powder, Dendrobium officinale powder is cell wall broken fine powder, hawthorn powder is seedless hawthorn low-temperature ground powder, tangerine peel powder is three-year aged tangerine peel dried and ground powder, and honey powder is spray dried food grade honey powder. After weighing, each powder raw material is sieved through an 80 mesh standard sieve to remove impurities, lumps and coarse fiber impurities, and ensure uniform particle size, laying the foundation for subsequent mixing. First, put the sieved Dendrobium officinale powder, hawthorn powder, and tangerine peel powder into a mixer to make the three active ingredients initially mixed evenly. Then, add honey powder to the initially mixed powder and continue mixing. The entire mixing process is carried out in a closed environment to prevent the powder from absorbing moisture and generating dust. The criteria for judging the end point of mixing are: the mixed material has a uniform color, no local color difference, no powder lumps, and no obvious granular texture or layering when rubbed by hand. This indicates that a homogeneous mixed material has been obtained. A high-speed wet granulation machine is used for humidification and mixing. All homogeneous mixtures are put into the mixing chamber of the granulator, and low-speed mixing is started. Food-grade purified water is used as the humidification medium. Purified water is slowly sprayed into the mixing chamber in batches at a rate of 15%-25% of the total mass of the mixture to avoid local clumping caused by adding water all at once. Mix until the material forms a uniform wet mixture. The wet mixture is judged by the following criteria: it can be formed into a ball when squeezed by hand, and it can be easily broken apart when lightly squeezed. There is no obvious powder sticking to the fingers after squeezing. The clumps can be easily broken apart when dropped. Avoid being too dry or too wet. The prepared wet mixture is transferred to a gyratory pellet mill and granulated using an 18-20 mesh food-grade stainless steel screen. After granulation, a small amount of oversized material is removed from the wet pellets to obtain wet pellets with uniform particle size. Spread the wet granules evenly on a food-grade drying tray, avoiding excessive thickness which can lead to uneven drying inside the granules and the formation of a hard outer shell. Place the drying tray in a hot air circulating drying oven for continuous drying. During the drying process, gently turn the wet granules in the drying tray once in a while to ensure even heating. The drying endpoint is determined by controlling the moisture content of the dry granules to 3.0%-5.0% (the conventional moisture standard for food-grade granule preparations). If a small amount of dry granules is not sticky to the touch and does not soften, it is considered qualified dry granules. After drying, remove the dry granules along with the drying tray and place them in a clean, ventilated cooling area to cool to room temperature to prevent the dry granules from absorbing moisture and softening due to temperature differences. The dried granules cooled to room temperature are fed into a swing granulator. A 16-18 mesh food-grade stainless steel screen is used for granulation to break up the slightly sticky granules during the drying process, remove fine powder and a small amount of large clumps that have not been broken up. After granulation, the resulting granules are sieved to remove the fine powder generated during granulation and drying, and to obtain finished granules with uniform particle size and good flowability. A fully automatic granule packaging machine is used for quantitative bagging, and aluminum-plastic composite film bags are selected as the packaging material.

[0050] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
