Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, and in particular to a traditional Chinese medicine decoction piece detection and screening device. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces refer to finished products made from raw medicinal materials through special processing under the guidance of TCM theory, according to the needs of syndrome differentiation and treatment, dispensing, and preparation. They are mostly in solid form, such as flakes, blocks, segments, and powders. The purpose of testing and screening is to ensure the quality and safety of TCM decoction pieces.

[0003] Currently, in the processing of Schizonepeta tenuifolia (a type of Chinese medicinal herb), the harvesting process easily picks up impurities such as weeds, soil, and sand, and the unsanitary processing environment easily introduces dust, debris, and other contaminants, resulting in a high impurity content in the processed herb. Existing screening methods are insufficient to efficiently and accurately remove impurities of various properties and forms, affecting not only the quality and efficacy stability of the processed herb but also potentially posing safety hazards due to impurity residues. Furthermore, these methods reduce the efficiency and pass rate of herb production. Moreover, existing detection technologies often rely on manual sensory judgment or simple chemical analysis methods, which are not only inefficient but also highly susceptible to subjective factors by the testing personnel, leading to misjudgments. These methods fail to meet the stringent quality and safety requirements of herb processing under the guidance of traditional Chinese medicine theory. Therefore, a technical solution that can effectively address these problems is urgently needed. Utility Model Content

[0004] This utility model provides a device for detecting and screening traditional Chinese medicine decoction pieces to solve the problems in the background art.

[0005] This utility model embodiment adopts the following technical solution: a traditional Chinese medicine decoction piece detection and screening device, including a support base, a sliding mounting frame, and a screening placement frame. The sliding mounting frame is installed on the upper end of the support base, and the screening placement frame is slidably installed inside the sliding mounting frame. A material discharge channel is provided inside the support base and below the screening placement frame. Both sides of the support base are open. The screening placement frame is similar to a sieve, with several sieve holes at its bottom for impurities to fall through. A movable reset component and a drive connection component are respectively connected to both sides of the screening placement frame. The drive connection component and the movable service component are slidably installed on both sides of the sliding mounting frame. A drive structure is also installed on the sliding mounting frame. The drive structure corresponds to the working end of the drive connection component on the sliding mounting frame. The drive structure can drive the drive connection component to move the screening placement frame horizontally in the sliding mounting frame. The movable reset structure can reset the screen placement frame after movement. A blower is provided on the side of the support base. The blowing end of the blower corresponds to the opening on one side of the support base. The opening on the other side of the support base is the discharge end of the material discharge channel.

[0006] Furthermore, one side of the sliding mounting bracket is provided with a mounting plate to facilitate the installation of the drive structure. The mounting plate allows the drive structure to correspond with the movable connection component on the sliding mounting bracket, and it also separates the drive structure from the blower.

[0007] In this application, by rationally designing the position and dimensions of the mounting plate, the drive structure can be precisely aligned with the drive connection assembly on the sliding mounting frame. This ensures that after the drive structure is started, it can smoothly drive the drive connection assembly through mechanical transmission, thereby allowing the screening rack to swing left and right within the sliding mounting frame. Furthermore, the mounting plate also isolates the drive structure from the blower. Since the blower generates airflow, heat, and potentially moisture during operation, the mounting plate separates it from the drive structure, effectively preventing adverse effects from the blower on the drive structure. This includes preventing airflow from interfering with the normal operation of the drive structure, preventing heat damage to the drive structure components, and preventing moisture from causing electrical components in the drive structure to become damp, thus ensuring the stable and reliable operation of the drive structure.

[0008] Furthermore, the sliding mounting frame has symmetrical sliding assembly slots on both sides to facilitate the installation of the screening placement frame, and symmetrical sliding connecting blocks are provided on both sides of the screening placement frame. When the screening placement frame is assembled into the sliding mounting frame, each sliding connecting block is located in a sliding assembly slot. The screening placement frame can be slidably positioned within the sliding mounting frame through the two sliding connecting blocks.

[0009] Furthermore, the movable reset assembly includes a connecting plate, a limiting rod, and a reset spring. There are two connecting plates, and multiple limiting rods and reset springs. The two connecting plates are symmetrically arranged on both sides of the multiple limiting rods. One connecting plate is located inside the sliding mounting frame and installed on the side wall of the screening rack, while the other connecting plate is located outside the sliding mounting frame. The multiple limiting rods are slidably located on one side of the sliding mounting frame. Each reset spring surrounds a limiting rod, and both sides of each reset spring are respectively connected to a connecting plate and the side wall of the sliding mounting frame.

[0010] Furthermore, the drive connection assembly, the second connection plate, the drive connection rod, and the limiting connection rod are provided. The second connection plate is disposed on the other side of the screening and placement frame. One end of the drive connection rod is disposed in the middle position of the second connection plate, and the other end of the drive connection rod passes through one side of the sliding mounting frame and is horizontally aligned with the working end of the drive structure. There are two limiting connection rods. One end of the two limiting connection rods is symmetrically disposed on both sides of the second connection plate, and the other end of the two limiting connection rods is slidably located on one side of the sliding mounting frame.

[0011] Furthermore, the drive structure includes a drive placement frame, a drive motor, a rotating shaft, a rotating connecting rod, and a rotating plate. The drive placement frame is mounted on the mounting plate, the drive motor is mounted on one side of the drive placement frame, the rotating shaft is rotatably mounted in the middle position inside the drive placement frame, the working end of the drive motor is connected to the drive shaft in the drive placement frame, the rotating connecting rod is mounted on the rotating shaft, and there are two rotating plates symmetrically arranged on both sides of the rotating connecting rod. When the rotating connecting rod rotates, the two rotating plates can push the drive connecting rod in an intermittent manner.

[0012] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0013] In this application, the synergistic effect of the left-right swing of the screening rack and the airflow of the blower achieves efficient removal of various impurities of different properties and forms, such as dust, debris, and weeds, from the medicinal herb Schizonepeta tenuifolia. Compared with traditional screening methods, this not only improves the screening efficiency of fine dust and debris but also effectively separates lighter weeds hidden in the medicinal herb slices, greatly reducing the amount of impurities remaining and comprehensively improving the screening effect.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 This utility model provides a device for detecting and screening Chinese herbal medicine slices, including a support base 1, a sliding mounting frame 2, and a screening rack 3. The sliding mounting frame 2 is installed on the upper end of the support base 1, and the screening rack 3 is slidably installed inside the sliding mounting frame. A material discharge channel 11 is provided inside the support base 1 and below the screening rack 3. Both sides of the support base 1 are open. The screening rack 3 is similar to a sieve, with several sieve holes at its bottom for impurities to fall through. A movable reset component 4 and a drive connection component 5 are respectively connected to both sides of the screening rack 3. The components are slidably mounted on both sides of the sliding mounting frame 2; the sliding mounting frame 2 is also equipped with a drive structure 6, which corresponds to the working end of the drive connection component 5 on the sliding mounting frame 2. The drive structure 6 can drive the drive connection component 5 to move the screening rack 3 horizontally in the sliding mounting frame 2, and the moving reset structure can reset the screening rack 3 after it has moved; a blower 7 is provided on the side of the support base 1, and the blowing end of the blower 7 corresponds to the opening provided on one side of the support base 1. The opening provided on the other side of the support base 1 is the discharge end of the material feeding channel 11.

[0023] The Chinese herbal medicine screening device in this application is placed below the spectral detection device or installed above the sliding mounting frame 2, so that its detection end corresponds vertically with the screening placement frame 3. In addition, the spectral detection device is a prior art device (such as the Haineng Instruments F960 near-infrared spectrometer). The spectral detection device can detect the Chinese herbal medicine during screening, and based on the synergistic effect of mechanical motion and airflow assistance, it can achieve efficient removal of impurities in the Chinese herbal medicine Schizonepeta tenuifolia.

[0024] The device uses a support base 1 as its basic load-bearing structure, on which a sliding mounting frame 2 is installed, providing a horizontal sliding track for the screening and placement frame 3. The screening and placement frame 3 resembles a sieve, with sieve holes at the bottom. Drive connection components 5 and moving reset components 4 are connected to its two sides respectively, and slide in cooperation with the sides of the sliding mounting frame 2. The drive structure 6 on the sliding mounting frame 2 corresponds to the working end of the drive connection component 5. When the drive structure 6 is activated, it drives the drive connection component 5 through mechanical transmission, causing the screening and placement frame 3 to swing left and right within the sliding mounting frame 2. During this swinging process, the medicinal herb slices, such as Schizonepeta tenuifolia, move accordingly. Dust, debris, and other fine impurities, due to their own weight and the inertia generated by the sieve's swing, pass through the sieve holes and fall into the feed channel 11 within the support base 1. Simultaneously, a blower 7 located at the feed channel 11 continuously operates, generating directional airflow within the channel. The airflow acts on two fronts: firstly, it pushes impurities falling into the feed channel 11, causing them to be discharged through the outlet end of the feed channel 11; secondly, the airflow acts upward through the sieve holes onto the medicinal herb slices, *Schizonepeta tenuifolia*, on the screening rack 3. Because *Schizonepeta tenuifolia* differs from lighter impurities such as weeds in mass and stress characteristics, the airflow causes the lighter impurities to be blown away and exposed, detaching from the *Schizonepeta tenuifolia*. Then, under the combined action of the swaying sieve and the airflow, these impurities pass through the sieve holes and fall into the feed channel 11, ultimately being discharged by the airflow generated by the blower 7, thus effectively removing impurities of different properties and forms.

[0025] In terms of testing, the spectroscopic detection device immediately initiates the detection process after the Chinese herbal medicine slices are placed on the screening rack. It emits light of a specific wavelength and collects the reflected or transmitted light signals from the medicinal slices, converting them into spectral data. This data is transmitted in real time to a connected data analysis system, which compares and analyzes it against pre-stored standard spectral data. For example, if a batch of Schizonepeta tenuifolia slices is found to have excessively high moisture content or contain unwanted impurities, the system will promptly issue an alarm and record the relevant data. Based on the test results, staff can further process the batch of medicinal slices, such as re-screening or drying, to ensure that the medicinal slices entering the next production stage meet quality standards.

[0026] This application, through the aforementioned impurity removal and detection process, avoids the contamination and interference of impurities on the components of traditional Chinese medicine decoction pieces, ensuring the purity and stability of the components of Schizonepeta tenuifolia decoction pieces, thereby improving its efficacy and meeting the strict requirements of traditional Chinese medicine theory for the quality and efficacy of traditional Chinese medicine decoction pieces, providing a reliable guarantee for clinical medication.

[0027] Preferably, one side of the sliding mounting bracket 2 is provided with a mounting plate 21 to facilitate the installation of the drive structure 6. The mounting plate 21 allows the drive structure 6 to correspond with the movable connection component on the sliding mounting bracket 2, and also separates the drive structure 6 from the blower 7.

[0028] In this application, by rationally designing the position and dimensions of the mounting plate 21, the drive structure 6 can be precisely aligned with the drive connection component 5 on the sliding mounting bracket 2. This ensures that after the drive structure 6 is started, it can smoothly drive the drive connection component 5 through mechanical transmission, thereby causing the screening rack 3 to swing left and right within the sliding mounting bracket 2. Furthermore, the mounting plate 21 also serves to isolate the drive structure 6 from the blower 7. Since the blower 7 generates airflow, heat, and potentially moisture during operation, the mounting plate 21 separates it from the drive structure 6, effectively preventing the adverse effects of the blower 7 on the drive structure 6. This includes preventing airflow from interfering with the normal operation of the drive structure 6, preventing heat from damaging the performance of the drive structure 6 components, and preventing moisture from causing the electrical components of the drive structure 6 to become damp, thus ensuring the stable and reliable operation of the drive structure 6.

[0029] Preferably, the sliding mounting frame 2 has symmetrical sliding assembly slots 22 on both sides to facilitate the installation of the screening placement frame 3. The screening placement frame 3 has symmetrical sliding connecting blocks 31 on both sides. When the screening placement frame 3 is assembled into the sliding mounting frame 2, each sliding connecting block 31 is located in a sliding assembly slot 22. The screening placement frame 3 can be slidably positioned in the sliding mounting frame 2 by means of two sliding connecting blocks 31.

[0030] In this application, symmetrical sliding assembly slots 22 are provided on both sides of the sliding mounting frame 2. These sliding assembly slots 22 are specifically designed for the installation of the screening rack 3. Sliding connecting blocks 31 are symmetrically arranged on both sides of the screening rack 3. When the screening rack 3 is assembled into the sliding mounting frame 2, each sliding connecting block 31 fits precisely into a sliding assembly slot 22. Through this precise fit, the screening rack 3 can slide stably and flexibly within the sliding mounting frame 2.

[0031] Preferably, the movable reset assembly 4 includes a connecting plate 41, a limiting rod 42, and a reset spring 43. There are two connecting plates 41, and multiple limiting rods 42 and reset springs 43. The two connecting plates 41 are symmetrically arranged on both sides of the multiple limiting rods 42. One connecting plate 41 is located inside the sliding mounting frame 2 and installed on the side wall of the screening placement frame 3. The other connecting plate 41 is located outside the sliding mounting frame 2. The multiple limiting rods 42 are slidably located on one side of the sliding mounting frame 2. Each reset spring 43 is surrounded by a limiting rod 42. The two sides of each reset spring 43 are respectively connected to a connecting plate 41 and the side wall of the sliding mounting frame 2.

[0032] In this application, when the drive structure 6 is activated, it drives the drive connection assembly 5 through mechanical transmission, thereby causing the screening placement rack 3 to swing left and right within the sliding mounting frame 2. During the swinging process of the screening placement rack 3, it drives the connected movable reset assembly 4 to move together, at which time the reset spring 43 is compressed or stretched. When the drive structure 6 stops driving, the reset spring 43, with its own elastic restoring force, pushes the connecting plate 41, thereby driving the screening placement rack 3 to reset along the guide direction of the limit rod 42, ensuring that the screening placement rack 3 can return to its initial position and prepare for the next screening operation. During the swinging process, the Chinese herbal medicine slices Schizonepeta tenuifolia move along with it, and the dust, debris and other small impurities in them, due to their own gravity and the inertia generated by the swinging of the screen, pass through the screen holes and fall into the feed channel 11 in the support base 1.

[0033] Preferably, the drive connection assembly 5, the second connection plate 51, the drive connection rod 52, and the limiting connection rod 53 are arranged as follows: the second connection plate 51 is disposed on the other side of the screening and placement rack 3; one end of the drive connection rod 52 is disposed in the middle position of the second connection plate 51; the other end of the drive connection rod 52 passes through one side of the sliding mounting frame 2 and is horizontally aligned with the working end of the drive structure 6; and two limiting connection rods 53 are provided, with one end of the two limiting connection rods 53 symmetrically disposed on both sides of the second connection plate 51, and the other ends of the two limiting connection rods 53 slidingly located on one side of the sliding mounting frame 2.

[0034] In this application, when the drive structure 6 is started, its working end transmits power to the drive connecting rod 52 through mechanical transmission, thereby causing the connecting plate 51 and the screening rack 3 to swing left and right within the sliding mounting frame 2. One end of the two limiting connecting rods 53 is symmetrically arranged on both sides of the connecting plate 51, and the other end slides on one side of the sliding mounting frame 2. The limiting connecting rods 53 play a limiting and guiding role during the swinging process of the screening rack 3, ensuring that the screening rack 3 swings stably along the preset horizontal direction, avoiding the screening rack 3 from deviating or shaking during the movement, and ensuring the stability and reliability of the screening process.

[0035] Preferably, the drive structure 6 includes a drive placement frame 61, a drive motor 62, a rotating shaft 621, a rotating connecting rod 622, and a rotating plate 623. The drive placement frame 61 is mounted on the mounting plate 21. The drive motor 62 is mounted on one side of the drive placement frame 61. The rotating shaft 621 is rotatably mounted in the middle position inside the drive placement frame 61. The working end of the drive motor 62 is connected to the drive shaft in the drive placement frame 61. The rotating connecting rod 622 is mounted on the rotating shaft 621. There are two rotating plates 623, which are symmetrically arranged on both sides of the rotating connecting rod 622. When the rotating connecting rod 622 rotates, the two rotating plates 623 can push the drive connecting rod 52 in an intermittent manner.

[0036] In this application, the drive mounting bracket 61 is installed on the mounting plate 21, providing a mounting base for components such as the drive motor 62 and the rotating shaft 621. The drive motor 62 is installed on one side of the drive mounting bracket 61 as a power source, and its working end is connected to the rotating shaft 621, which is rotatably installed in the middle position inside the drive mounting bracket 61, enabling it to convert electrical energy into rotational mechanical energy of the rotating shaft 621. The rotating connecting rod 622 is installed on the rotating shaft 621 and rotates synchronously with the rotating shaft 621; two rotating plates 623 are symmetrically arranged on both sides of the rotating connecting rod 622. When the rotating connecting rod 622 rotates, the two rotating plates 623 push the drive connecting rod 52 in the drive connecting assembly 5 in an intermittent manner.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
