Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine processing technology, and specifically discloses a pretreatment method for traditional Chinese medicine. Background Technology

[0002] Isatis root is the dried root of the plant Isatis indigotica or Isatis tinctoria. It is slender and cylindrical, about 10-30 cm long and 3-8 mm in diameter. The surface is light grayish-yellow, rough, with longitudinal wrinkles and transverse spots. It can usually be made into Isatis root granules, which have the effects of clearing heat and detoxifying, preventing colds, and relieving sore throat. It can effectively treat human diseases.

[0003] The current method for preparing Isatis root granules is as follows: Washed Isatis root is decocted twice, the first time for 2 hours and the second time for 1 hour. The decoction is filtered, the filtrates are combined, and concentrated to a relative density of 1.2 (50℃). Then, ethanol is added to achieve an alcohol content of 60%. The mixture is allowed to settle, the supernatant is collected, the ethanol is recovered, and the solution is concentrated to a suitable volume. Appropriate excipients (dextrin or sucrose powder and dextrin) are added to form granules. However, current pretreatment of Isatis root only involves washing; no cutting or other processing is performed. After washing, the Isatis root is immediately placed in a pot for decoction, meaning the whole root is used. This results in slow extraction of medicinal properties during decoction, and a large amount of medicinal substances are wasted in the dregs. Therefore, the inventor has provided a pretreatment method for traditional Chinese medicine to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the traditional pretreatment process of Isatis indigotica, the roots are not cut, which leads to slow extraction of medicinal properties and waste of medicinal substances.

[0005] To achieve the above objectives, the basic solution of the present invention provides a pretreatment method for traditional Chinese medicinal materials, comprising the following steps:

[0006] Step S1, Material Selection: Select mature Isatis root medicinal materials;

[0007] Step S2, Cleaning: Use an integrated cleaning and cutting device to remove the mud and impurities from the surface of the Isatis root;

[0008] Step S3, Cutting: Use an integrated cleaning and cutting device to cut the cleaned Isatis root into sections;

[0009] The integrated cleaning and cutting device includes a housing, a cleaning component, a cutting component, and a conveying component that drives the Isatis root to move sequentially along the cleaning component and the cutting component.

[0010] The cleaning assembly includes several nozzles respectively disposed on both sides of the conveying assembly path;

[0011] The cutting assembly includes baffles and cutters respectively located on both sides of the conveying assembly path. The housing is provided with a loading frame, and a sliding frame is slidably connected to the loading frame. The top of the sliding frame is connected to the cutter, and the bottom of the sliding frame extends out of the loading frame and is provided with several cutter return springs between it and the outer bottom surface of the loading frame. A cam that can compress the bottom of the sliding frame is rotatably connected inside the housing.

[0012] The principle and effect of this basic scheme are as follows:

[0013] 1. Compared with the prior art, the present invention adopts a pretreatment process of cleaning and cutting in an integrated cleaning and cutting device for Isatis root, so that the pretreated Isatis root is in the form of segments or blocks. This makes it easier for the medicinal properties contained in Isatis root to penetrate into the decoction during the subsequent decoction process. This solves the problem that the traditional Isatis root pretreatment process does not cut the Isatis root, resulting in slow extraction of medicinal properties and waste of medicinal substances.

[0014] 2. In this invention, a conveying component is used to move the Isatis root along the cleaning component and the cutting component in sequence. After being cleaned, the Isatis root is moved to the position of the cutting component. At the same time, a cam squeezes the sliding frame to move the cutter as a whole. This causes the cutter to move towards the baffle and cut the Isatis root located between the cutter and the baffle. The cut Isatis root falls directly into the loading frame for collection, so as to facilitate the subsequent decoction process.

[0015] Furthermore, the conveying assembly includes chains symmetrically arranged within the housing, a clamping mechanism between the two chains, and a drive component for driving the chains. The clamping mechanism includes mounting seats respectively mounted on the two chains, a fixed plate and a sliding plate positioned between the mounting seats. The fixed plate and the sliding plate each have several mounting holes on their adjacent sides, and clamping springs are positioned between opposing mounting holes. The two ends of the sliding plate are slidably connected to the two mounting seats along the axial direction of the clamping springs. When the fixed plate contacts the sliding plate, the clamping springs are in a stretched state. The tension of the springs causes the sliding plate to move closer to the fixed plate, clamping the basket between the fixed plate and the sliding plate. Simultaneously, the two chains move the mounting seats, causing the clamped basket to move.

[0016] Furthermore, the chain's movement path is rectangular, with nozzles positioned on either side of the chain's upward movement path. Baffles and cutters are located on the upper and lower sides of the top of the chain's movement path, respectively. A combing component is also provided between the cleaning and cutting components. This design prevents wastewater from re-contaminating the cleaned Isatis root strip and affecting the cleaning effect. Simultaneously, it allows the cut Isatis root to fall directly into the loading frame for centralized collection, preventing it from falling to other parts of the container. The combing component prevents the Isatis root from becoming tangled and affecting the cutting effect.

[0017] Furthermore, the combing assembly includes a support plate disposed at the top of the chain's movement path and a combing block slidably connected to the support plate and insertable between two adjacent blue strips. The combing block, insertable between adjacent blue strips, ensures that adjacent blue strips are independent of each other, preventing them from intertwining and affecting the cutting effect. Simultaneously, the slidable connection between the combing block and the support plate allows the combing block to slide when pressed by the fixed plate and sliding plate, preventing the combing block from interfering with the movement of the clamping assembly.

[0018] Furthermore, the bottom of the combing block extends into the housing and is slidably connected to the housing. A retaining ring is provided at the shaft end of the combing block, and a sleeve plate is provided inside the housing to allow the combing block to slide. A retaining ring return spring is provided between the retaining ring and the sleeve plate. The sleeve plate, retaining ring, and retaining ring return spring facilitate timely reset of the combing block.

[0019] Furthermore, the support plate is inclined toward the cleaning assembly along the combing block. This arrangement allows water adhering to the indigo root to flow back to the cleaning assembly as it moves on the support plate.

[0020] Furthermore, the sliding plate is fixedly connected to an adjusting rod, one end of which passes through the fixed plate. The housing also includes a release protrusion located along the movement path of the adjusting rod, which presses the adjusting rod to release the clamping mechanism and thus the basket root. This facilitates moving the sliding plate away from the fixed plate, thereby simplifying the loading and unloading of the basket root.

[0021] Furthermore, the release protrusion is located vertically at the end of the chain's movement path furthest from the cleaning assembly. A guide plate is hinged inside the housing below the release protrusion, and the guide plate is inclined with its bottom end facing the loading frame. This arrangement allows the portion of the basket material clamped by the fixing plate and sliding plate to fall into the loading frame after the basket material is cut, preventing the clamped portion from being wasted. Simultaneously, the inclined hinge of the guide plate allows it to be pressed and moved when the fixing plate and sliding plate contact it, thus preventing the guide plate from interfering with the normal movement of the fixing plate and sliding plate.

[0022] Furthermore, the housing is provided with a side plate for mounting the loading frame, and a guide return spring is provided between the guide plate and the side plate. The use of a guide return spring facilitates timely repositioning of the guide plate.

[0023] Furthermore, the loading frame is inclined at the bottom and has an opening on its side that communicates with the outside of the box. This facilitates the discharge of the cut Isatis root for subsequent processing. Attached Figure Description

[0040] A pretreatment method for traditional Chinese medicinal materials, taking Isatis root as an example, uses an integrated cleaning and cutting device to pretreat the Isatis root. In this embodiment, the integrated cleaning and cutting device includes a housing 1, a conveying assembly, a cleaning assembly, and a cutting assembly housed within the housing 1, as detailed below:

[0041] Box 1: An opening is provided on the left side of Box 1 to facilitate the placement or removal of Isatis root from Box 1. A water collection tank 5 is provided on the bottom right side of Box 1, and the water collection tank 5 is connected to a drain pipe.

[0042] Conveying assembly: The conveying assembly includes chains 2 symmetrically arranged within the housing 1, a clamping mechanism 3 located between the two chains 2, and a driving component for driving the chains 2; such as Figure 1 and Figure 3 As shown, the movement path of chain 2 is rectangular, rotating counterclockwise. Eight sprockets are symmetrically arranged front and rear inside the housing 1. The four front sprockets and four rear sprockets are located at the corners of the rectangular movement path of chain 2. The sprockets at corresponding positions on the front and rear sides are coaxially connected. The driving component is a drive motor located at the rear of the housing 1. The drive motor drives one of the sprockets to rotate in an intermittent manner, as shown... Figure 5 As shown, the clamping mechanism 3 includes mounting seats 302 respectively mounted on two chains 2, a fixed plate 303 and a sliding plate 304 disposed between the mounting seats 302. The fixed plate 303 and the sliding plate 304 each have several mounting holes on their adjacent sides, and clamping springs 305 are disposed between opposing mounting holes. Both ends of the sliding plate 304 are slidably connected to the two mounting seats 302 along the axial direction of the clamping springs 305. An adjusting rod 306 is fixedly connected to the sliding plate 304, with one end of the adjusting rod 306 passing through the bottom of the fixed plate 303. When the fixed plate 303 contacts the sliding plate 304, the clamping springs 305 are in a stretched state. The fixed plate 303 and the sliding plate 304 each have several concave surfaces on their adjacent sides, with rubber pads 301 having several protrusions inside. When the fixed plate 303 contacts the sliding plate 304, the two concave surfaces close to form a placement cavity that can clamp the basket.

[0043] like Figure 6 and Figure 7 As shown, both the fixed plate 303 and the sliding plate 304 have semicircular rings rotatably connected to each other on their adjacent sides. The semicircular ring on the fixed plate 303 is the bottom semicircular ring 308, and the semicircular ring on the sliding plate 304 is the top semicircular ring 309. The upper surface of the bottom semicircular ring 308 is symmetrically provided with connecting grooves, and the lower surface of the top semicircular ring 309 is symmetrically provided with connecting blocks 310 that fit the connecting grooves. Concave surfaces are respectively provided on the inner walls of the bottom semicircular ring 308 and the top semicircular ring 309. Both the fixed plate 303 and the sliding plate 304 have cavities. A sliding plate 311 is slidably connected to the cavity of the fixed plate 303. The side of the sliding plate 311 near the bottom semicircular ring 308 has a rack, and the side of the bottom semicircular ring 308 near the sliding plate 311 has several teeth that can engage with the rack. The two ends of the sliding plate 311 extend out of the mounting seats 302 on both sides and are provided with spherical sliders 307. It also includes guide rails symmetrically arranged inside the housing 1, such as... Figure 2 , Figure 4 and Figure 8 As shown, guide rail plates 9 are provided on both the front and rear sides of the box 1. Two guide rails 4 are connected to each guide rail plate 9. The two guide rails 4 form a guide rail that cooperates with the slider 307. The slider 307 is slidably connected in the guide rail. The bottom surface of the vertical guide rail at the right end of the rectangle located in the movement path of the chain 2 is a concave-convex surface 901, and the concave-convex surfaces 901 of the front and rear guide rails fit together to keep the distance between the ground inside the two guide rails stable.

[0044] like Figure 6 and Figure 7 As shown, each cavity is symmetrically provided with arc-shaped limiting grooves. At both ends of the semicircular ring, there are cylindrical limiting blocks 312 that are slidably connected in the limiting grooves. The top of the cavity of the sliding plate 304 is provided with a magnetic block 313. The limiting blocks 312 at both ends of the semicircular ring of the sliding plate 304 can be magnetically attracted to the magnetic block 313.

[0045] Two fixing plates 303 and a sliding plate 304 are provided between the mounting bases 302, so that when one pair of fixing plates 303 and sliding plates 304 releases the basket root, the other pair of fixing plates 303 and sliding plates 304 can still clamp the basket root. A first protrusion 7 and a release protrusion are respectively provided inside the housing 1 and fixed to each other. The first protrusion 7 is located on the right vertical path, and the release protrusion is located on the left vertical path. Both the first protrusion 7 and the release protrusion are located on the movement path of the adjusting rod 306, and the height of the release protrusion is higher than that of the first protrusion 7. When the first protrusion 7 presses against the adjusting rod 306, gaps are formed between the top semicircular ring 309 and the bottom semicircular ring 308 of the corresponding fixed plate 303 and sliding plate 304 and the blue root, reducing the clamping effect on the blue root. When the protrusion is released from pressing against the adjusting rod 306, the top semicircular ring 309 and the bottom semicircular ring 308 of the corresponding fixed plate 303 and sliding plate 304 release the blue root. The length of the first protrusion 7 is less than the distance between the two fixed plates 303, and the length of the releasing protrusion is greater than the distance between the two fixed plates 303.

[0046] Cleaning assembly: The cleaning assembly includes mounting plates 6 located vertically on the left and right sides of the chain 2 drive path, and several nozzles mounted on the mounting plates 6. The nozzles face between the two mounting plates 6, and a first protrusion 7 is mounted on the left mounting plate 6. The nozzles are connected to water inlet pipes, which pass through the mounting plates 6 and exit from the side of the housing 1.

[0047] The cutting components are located on the top and bottom sides of the top of the chain 2 drive path, and a combing component is also provided between the cleaning component and the cutting component.

[0048] Organizing components: such as Figure 9As shown, the combing assembly includes a support plate 13 positioned at the top of the path of the chain 2 and a combing block 14 slidably connected to the support plate 13 and insertable between two adjacent blue rings. The combing block 14 is located in the gap between adjacent top semicircular rings 309 or bottom semicircular rings 308. The support plate 13 is inclined towards the cleaning assembly along the combing block 14, and the other end of the support plate 13 extends to the cutting assembly. The upper surface of the combing block 14 is a slope that is higher on the left and lower on the right. Figure 11 As shown, the bottom of the combing block 14 extends into the box body 1 and is slidably connected to the box body 1. The shaft end of the combing block 14 is provided with a retaining ring 1401. The box body 1 is provided with a sleeve plate that allows the combing block 14 to slide. A retaining ring return spring 1402 is provided between the retaining ring 1401 and the sleeve plate.

[0049] Cutting assembly: The cutting assembly includes baffles 8 and cutters 15 respectively located on the upper and lower sides of the top of the chain 2 transmission path. A loading frame 19 is provided inside the housing 1. Figure 12 and Figure 13 As shown, a sliding frame 20 is vertically slidably connected to the loading frame 19. The top of the sliding frame 20 is connected to the cutter 15. The bottom of the sliding frame 20 extends out of the loading frame 19 and is provided with several cutter return springs 21 between it and the outer bottom surface of the loading frame 19. A cam 18 that can squeeze the bottom of the sliding frame 20 is rotatably connected inside the housing 1.

[0050] like Figure 10 As shown, the output shaft of the drive motor extends into the housing and is coaxially connected to a sector gear 16. A cam 18 is coaxially connected to an adjusting gear 1701 that can mesh with the sector gear 16. One of the sprockets is coaxially connected to a transmission gear 1702 that can mesh with the sector gear 16. When the sector gear 16 meshes with the adjusting gear 1701, the adjusting gear 1701 and the cam rotate for one complete cycle. When the sector gear 16 meshes with the transmission gear 1702, the transmission gear 1702, the sprocket, and the chain 2 rotate the distance between the two clamping mechanisms 3. When the sector gear 16 meshes with the adjusting gear 1701, the sector gear 16 disengages from the transmission gear 1702, and vice versa.

[0051] Inside the housing 1, there is a guide plate 11 hinged below the release protrusion. The guide plate 11 is inclined and the bottom end of the guide plate 11 faces the loading frame 19. Correspondingly, there is a side plate 10 inside the housing 1 for mounting the loading frame 19. A guide return spring 12 is provided between the guide plate 11 and the side plate 10. The bottom of the loading frame is inclined and the side of the loading frame 19 has an opening that communicates with the outside of the housing 1.

[0052] The preprocessing method in this embodiment includes the following steps:

[0053] Step S1, Material Selection: Select mature Isatis root medicinal materials;

[0054] Step S2, Cleaning: Use an integrated cleaning and cutting device to remove dirt and impurities from the surface of the Isatis root. Specifically, first arrange the Isatis roots sequentially on an auxiliary plate, ensuring that the ends of the Isatis roots extend beyond the end of the auxiliary plate. Drive the drive motor to drive the sector gear 16, causing the chain 2 to intermittently move the clamping mechanism 3. When the chain 2 and the clamping mechanism 3 stop, extend the auxiliary plate into the box 1 from the left side, so that the ends of the Isatis roots pass through the corresponding top semicircular rings 309 and bottom semicircular rings 308 of the clamping mechanism 3 from top to bottom and extend to the top semicircular ring 309. 09. Below the bottom semicircular ring 308, the top semicircular ring 309 and the bottom semicircular ring 308 are kept apart by the release protrusion. Then, the motor drives the clamping mechanism 3 to move, causing the top semicircular ring 309 and the bottom semicircular ring 308 to disengage from the release protrusion and lock together, fixing the corresponding blue root. The auxiliary plate is then removed for the next arrangement of the blue root. The chain 2 drives the clamping mechanism 3 to move along the bottom to the right and gradually move upward. During this process, the blue root is washed by the nozzle during the movement, and the slider 307 and... The concave and convex surfaces 901 within the guide rail engage with each other to move relative to the fixed plate 303. This movement, via the rack and pinion teeth, drives the bottom semicircular rings 308 and top semicircular rings 309 to move, causing the clamped basket root to rotate relative to the fixed plate 303 and sliding plate 304. This ensures that all sides of the clamped basket root are directly washed by the nozzles. Furthermore, the first protrusion 7 presses against the adjusting rod 306 of one of the sliding plates 304, causing that sliding plate 304 to move away from the corresponding fixed plate 303, thus achieving the desired effect. A gap is formed between the sliding plate 304 and the fixed plate 303 and the indigo root. At the same time, the indigo root is clamped by another fixed plate 303 and the sliding plate 304. Meanwhile, the other fixed plates 303 and the sliding plate 304 also drive the clamped indigo root to rotate, so that the indigo root and the rubber pad 301 of the fixed plate 303 and the sliding plate 304 rotate relative to each other. This not only allows water to flow between the rubber pad 301 and the indigo root, but also allows the indigo root and the rubber pad 301 to rub relative to each other, thus cleaning the indigo root at that location.

[0055] Step S3, Cutting: The cleaned Isatis root is cut into sections using an integrated cleaning and cutting device. Specifically, the cleaned Isatis root passes through a combing mechanism driven by chain 2. When the fixed plate 303 and sliding plate 304 contact the combing block 14, the combing block 14 slides as it is squeezed. When the fixed plate 303 and sliding plate 304 disengage from the combing block 14, the combing block 14 moves upward under the action of the combing return spring. Because the Isatis root is clamped by the top semicircular ring 309 and the bottom semicircular ring 308, The contact points between the Isatis root and the top semicircular ring 309 and bottom semicircular ring 308 are less prone to tangling. The combing block 14 is inserted upwards from the right side of the bottom semicircular ring 308 between two adjacent Isatis roots, achieving the purpose of combing the entire Isatis root, so that each Isatis root is distributed in strips along the support plate 13, facilitating subsequent cutting. Furthermore, as the Isatis root moves on the support plate 13, any water accumulated on it can flow back to the cleaning component. When the Isatis root moves to the cutting component, the fan... The rotation of gear 16 drives the adjusting gear 1701 to rotate intermittently, while the transmission gear 1702 stops moving, keeping the blue root relatively stationary. Each engagement of the sector gear 16 drives the adjusting gear 1701 to rotate a full cycle, which in turn drives the cam 18 to rotate a full cycle, causing the sliding frame 20 to move up and down a full cycle, which in turn drives the cutter 15 to move up and down a full cycle. This causes the cutter 15 to move towards the baffle 8, thus moving the blue root located between the cutter 15 and the baffle 8 (i.e., the blue root located behind the clamping mechanism 3). The isatis root is cut, and the cut isatis root falls directly into the loading frame 19 for centralized collection. At the same time, the isatis root clamped by the clamping mechanism 3 continues to move under the drive of the chain 2 until it moves to the vertical position on the left, so that the release protrusion squeezes the adjusting rod 306, causing the clamping mechanism 3 to release the isatis root. The released isatis root falls under the action of gravity and falls into the loading frame 19 under the action of the guide plate 11, so as to facilitate the subsequent decoction process. The next auxiliary plate is extended into the box 1 for the pretreatment of the next batch of isatis root.
