Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material processing equipment, specifically to a cutting device for Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicine (TCM) materials are mainly composed of plant-based medicines (roots, stems, leaves, and fruits), animal-based medicines (internal organs, skin, bones, and other organs), and mineral-based medicines. Because plant-based medicines constitute the majority of TCM materials, they are also called Chinese herbal medicines. Currently, TCM materials are processed according to TCM theory, such as cutting them into segments, chunks, or petals, to form segmented, block-shaped, or petal-shaped TCM herbs. After further processing, these segmented, block-shaped, or petal-shaped TCM herbs can be directly used in TCM clinical practice.

[0003] However, in the process of cutting and processing Chinese medicinal materials into segments, blocks, or petals, scissors are usually used. When cutting, workers need to hold the medicinal materials in their hands and place them in the scissors, and then operate the scissors to cut and process the medicinal materials. This process can easily result in cuts and scratches to workers, leading to a low level of safety in the workers' working environment.

[0004] Furthermore, when using scissors to cut Chinese medicinal materials, impurities often adhere to these scissors during use. Since the scissors directly contact the cut surfaces of the segmented, block-shaped, or petal-shaped Chinese medicinal materials, these impurities can easily adhere to the cut surfaces. Therefore, to address the above technical problems, the applicant has designed a Chinese medicinal material cutting device that can clean the cut surfaces of segmented, block-shaped, or petal-shaped Chinese medicinal materials during the cutting process, thereby greatly reducing the amount of impurities adhering to the cut surfaces of the segmented, block-shaped, or petal-shaped Chinese medicinal materials. Utility Model Content

[0005] The present invention aims to provide an application and a cutting device for Chinese medicinal materials that can clean the cut surface of segmented, block-shaped, or petal-shaped Chinese medicinal materials, thereby greatly reducing the amount of impurities adhering to the cut surface of segmented, block-shaped, or petal-shaped Chinese medicinal materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] 1) A herb-cutting device for Chinese medicinal materials, comprising a support base, the upper surface of which has a conveyor belt that moves along the conveying direction, a tool holder mounted on the support base directly above the conveyor belt, the tool holder having a cutting blade and a cleaning roller arranged sequentially along the conveying direction, the cutting blade having a cutting edge facing the lower side of the conveyor belt for cutting the Chinese medicinal materials, the cutting blade having a driving component on the upper side away from the conveyor belt for moving the cutting blade up and down along the height direction of the tool holder, the cleaning roller having a gap between itself and the conveyor belt for the passage of segmented, block-shaped, or petal-shaped Chinese medicinal materials after cutting, and the surface of the cleaning roller being evenly distributed with bristles for cleaning the cut surfaces of segmented, block-shaped, or petal-shaped Chinese medicinal materials.

[0008] In the above technical solution, the conveyor belt transports the Chinese medicinal materials to the cutter holder. The drive unit moves the cutting blade downwards along the height of the cutter holder, causing the cutting blade to cut the Chinese medicinal materials towards the blade edge of the conveyor belt. The cut Chinese medicinal materials are formed into segments, blocks, or petals. Then, the segments, blocks, or petals continue to be transported towards the cleaning roller with the conveyor belt. Since the gap between the cleaning roller and the conveyor belt is only wide enough for the segments, blocks, or petals to pass through, the Chinese medicinal materials cannot pass through the gap to be output when the cutting blade is not cutting them. This allows us to determine whether the cutting blade is operating normally, thus ensuring the normal cutting of the Chinese medicinal materials.

[0009] In addition, the bristles on the surface of the cleaning roller can clean the segmented, block-shaped, or petal-shaped Chinese medicines conveyed by the conveyor belt. Since the segmented, block-shaped, or petal-shaped Chinese medicines are conveyed with the conveyor belt, they will come into contact with the cleaning roller. Therefore, the cleaning roller will rotate synchronously when the segmented, block-shaped, or petal-shaped Chinese medicines are conveyed. During the rotation of the cleaning roller, the cut surfaces of the segmented, block-shaped, or petal-shaped Chinese medicines can be cleaned, and impurities on the cut surfaces of the segmented, block-shaped, or petal-shaped Chinese medicines can be removed, greatly reducing the impurities on the cut surfaces of the segmented, block-shaped, or petal-shaped Chinese medicines.

[0010] 2) The herb-cutting device for Chinese medicinal materials as described in 1), wherein:

[0011] The upper surface of the support base is fixed with protective housings located on both sides of the conveyor belt. The protective housings include two crossbars symmetrically arranged with the conveyor belt as the center line. The tool holder is mounted between the two crossbars. The lower surface of the crossbars is fixed on the support base. The cleaning roller is rotatably connected to the crossbars.

[0012] The protective shell in the above technical solution protects the Chinese medicinal materials transported on the conveyor belt. The protective shell consists of two crossbars symmetrically arranged around the conveyor belt's center line, and a baffle plate on the upper surface of each crossbar. The crossbars in the protective shell connect the support base and the tool holder, and also support the tool holder, allowing the cleaning roller on the tool holder to be positioned on the upper surface of the conveyor belt. The two crossbars also support the cleaning roller, so that when the cleaning roller comes into contact with segmented, block-shaped, or petal-shaped Chinese medicinal materials, the material being transported by the conveyor belt causes the cleaning roller to rotate, thus cleaning impurities from the material during transport.

[0013] 3) The herb-cutting device for Chinese medicinal materials as described in 2), wherein:

[0014] The upper surface of the crossbar has a baffle plate extending toward the conveyor belt, and the cleaning roller is disposed below the baffle plate.

[0015] The baffle designed in the above technical solution is used to block the splashing of medicinal debris when cutting Chinese medicinal materials and can also prevent splashing of Chinese medicinal materials that are smaller in size. At the same time, the cleaning roller is set below the baffle to clean the Chinese medicinal materials after cutting.

[0016] 4) The herb-cutting device for Chinese medicinal materials as described in 2), wherein:

[0017] The cleaning roller has a rotating shaft that passes through it along its axial direction. One end of the rotating shaft passes through a crossbar corresponding to that end and is fixedly connected. The other end of the rotating shaft passes through a crossbar corresponding to that end and is fixedly connected.

[0018] In the above technical solution, the rotating shaft supports the cleaning roller. Since the cleaning roller is loosely fitted on the rotating shaft, during the conveyor belt transport of segmented, block-shaped, or petal-shaped Chinese medicine, the Chinese medicine will push the cleaning roller to rotate around the rotating shaft, thus cleaning the segmented, block-shaped, or petal-shaped Chinese medicine while the cleaning roller rotates. Crossbars are inserted into the corresponding ends of the rotating shaft and fixedly connected, thereby limiting the position of the rotating shaft and thus limiting the position of the cleaning roller.

[0019] 5) The herb-cutting device for Chinese medicinal materials according to 1), wherein:

[0020] The support base is rotatably connected to a drive wheel and a driven wheel at both ends along the conveying direction. The conveyor belt is wound between the drive wheel and the driven wheel. The drive wheel is coaxially connected to a drive motor mounted on the support base. A support plate is fixed on the support base between the drive wheel and the driven wheel. The upper and lower surfaces of the support plate are in contact with the conveyor belt. The support plate is located directly below the tool holder.

[0021] In the above technical solution, when the drive motor coaxially connects the output shaft of the drive motor to the drive wheel, starting the drive motor causes the output shaft to rotate, which in turn drives the drive wheel to rotate. This rotation of the drive wheel causes the conveyor belt to rotate and move, thereby driving the driven wheel to rotate. At the same time, the support plate set between the drive wheel and the driven wheel can contact the conveyor belt. This ensures that the Chinese medicinal materials move along the conveyor direction when the conveyor belt moves, and the upper surface of the support plate can support the conveyor belt during the movement of the Chinese medicinal materials. Meanwhile, when the cutting blade in the cutter holder set directly above the support plate cuts the Chinese medicinal materials, the support plate supports the cutting force applied by the cutting blade. This ensures that the Chinese medicinal materials can be cut into segments, blocks, or petals.

[0022] 6) The herb-cutting device for Chinese medicinal materials according to 1), wherein:

[0023] The driving component includes a servo motor mounted on the top of the tool holder. The output shaft of the servo motor extends toward the cutting blade and is fixedly connected to the upper side of the cutting blade. Two guide pillars are symmetrically arranged inside the tool holder with the servo motor output shaft as the center line. The two sides of the cutting blade pass through the corresponding guide pillars and can move up and down along the height direction of the tool holder.

[0024] In the above technical solution, the servo motor drives the cutting blade to move up and down along the height direction of the tool holder via the output shaft of the servo motor. During the downward movement along the height direction of the tool holder, the cutting blade cuts the Chinese medicinal materials on the conveyor belt into segmented, block-shaped, or petal-shaped Chinese medicinal materials. During the upward and downward movement of the cutting blade along the height direction of the tool holder, the guide posts set on both sides of the tool holder allow the cutting blade to pass through and guide the upward and downward movement of the cutting blade.

[0025] 7) The herb-cutting device for Chinese medicinal materials according to 1), wherein:

[0026] An output plate extending outward along the conveying direction is fixed to the side of the support base, and the upper surface of the output plate is flush with the upper surface of the conveyor belt.

[0027] In the above technical solution, the output plate is set on the side of the support along the conveying direction, and the upper surface of the output plate is flush with the upper surface of the conveyor belt. This allows the segmented, block-shaped, or petal-shaped Chinese medicines conveyed by the conveyor belt to be transported to the output plate. This makes it convenient for staff to manually inspect the cutting status of the segmented, block-shaped, or petal-shaped Chinese medicines on the output plate.

[0028] Compared with the prior art, this utility model also has the following technical effects:

[0029] Compared to existing technologies, this invention uses a drive motor to power a conveyor belt, which transports the medicinal herbs along the conveying direction to directly below the cutting blade. A servo motor then drives the cutting blade to cut the herbs into segments, blocks, or petals along the height direction. This eliminates the need for workers to manually handle the herbs, reducing the risk of cuts or scratches. Furthermore, the cleaning roller designed in this invention cleans the cut surfaces of the segmented, block, or petal-shaped herbs, significantly reducing the amount of impurities adhering to these surfaces.

[0032] Figure 3 for Figure 2 Sectional view of AA. Detailed Implementation

[0033] The following detailed description illustrates the specific implementation method:

[0034] The reference numerals in the accompanying drawings include: protective housing 1, support base 2, output plate 3, drive motor 4, tool holder 5, servo motor 6, conveyor belt 7, cleaning roller 8, cutting blade 9, guide column 10, and support plate 11.

[0035] See the example. Figure 1 , Figure 2 and Figure 3As shown, the herb-cutting device applied to traditional Chinese medicine materials in this embodiment includes a support base 2. The upper surface of the support base 2 has a conveyor belt 7 that moves along the conveying direction. An output plate 3 extending outward along the conveying direction is fixed to the side of the support base 2, and the upper surface of the output plate 3 is flush with the upper surface of the conveyor belt 7. In this embodiment, the output plate 3 is arranged on the side of the support base 2 along the conveying direction, and the upper surface of the output plate 3 is flush with the upper surface of the conveyor belt 7. This allows the segmented, block-shaped, or petal-shaped traditional Chinese medicine materials conveyed by the conveyor belt 7 to be transported to the output plate 3, which facilitates manual inspection of the cutting status of the segmented, block-shaped, or petal-shaped traditional Chinese medicine materials by the workers on the output plate 3.

[0036] A tool holder 5 is mounted on the support base 2, located directly above the conveyor belt 7. The tool holder 5 is provided with a cutting blade 9 and a cleaning roller 8 along the conveying direction. The cutting blade 9 has a blade facing the lower side of the conveyor belt 7 for cutting Chinese medicinal materials. The cutting blade 9 has a driving component on the upper side away from the conveyor belt 7 to move the cutting blade 9 up and down along the height direction of the tool holder 5. There is a gap between the cleaning roller 8 and the conveyor belt 7 for the segmented, blocky, or petal-shaped Chinese medicinal materials to pass through after cutting. The surface of the cleaning roller 8 is evenly distributed with bristles for cleaning the cut surfaces of segmented, blocky, or petal-shaped Chinese medicinal materials.

[0037] In this embodiment, the conveyor belt 7 transports the Chinese medicinal materials to the cutter holder 5. The drive unit drives the cutting blade 9 to move downward along the height direction of the cutter holder 5, so that the cutting blade 9 cuts the Chinese medicinal materials towards the blade of the conveyor belt 7. The cut Chinese medicinal materials are formed into segmented, block-shaped, or petal-shaped Chinese medicinal materials. Then, the segmented, block-shaped, or petal-shaped Chinese medicinal materials continue to be transported towards the cleaning roller 8 along the conveyor belt 7. Since the gap between the cleaning roller 8 and the conveyor belt 7 can only be passed through segmented, block-shaped, or petal-shaped Chinese medicinal materials, when the cutting blade 9 is not cutting the Chinese medicinal materials, the Chinese medicinal materials cannot pass through the gap and be output outward. This allows us to determine whether the cutting blade 9 is operating normally, thereby ensuring the normal cutting of the Chinese medicinal materials.

[0038] Furthermore, the bristles on the surface of the cleaning roller 8 can clean the segmented, blocky, or petal-shaped Chinese medicines conveyed by the conveyor belt 7. Since the segmented, blocky, or petal-shaped Chinese medicines are conveyed along with the conveyor belt 7, they will come into contact with the cleaning roller 8. Therefore, the cleaning roller 8 will rotate synchronously when the segmented, blocky, or petal-shaped Chinese medicines are conveyed. During the rotation of the cleaning roller 8, the cut surfaces of the segmented, blocky, or petal-shaped Chinese medicines can be cleaned, and impurities on the cut surfaces of the segmented, blocky, or petal-shaped Chinese medicines can be removed, greatly reducing the impurities on the cut surfaces of the segmented, blocky, or petal-shaped Chinese medicines.

[0039] See Figure 2As shown, in this embodiment, the upper surface of the support base 2 is fixed with protective housings 1 located on both sides of the conveyor belt 7. The protective housings 1 are made of steel. The protective housings 1 include two crossbars symmetrically arranged with the conveyor belt 7 as the center line. The tool holder 5 is mounted between the two crossbars. The lower surface of the crossbars is fixed on the support base 2. The cleaning roller 8 is rotatably connected to the crossbars.

[0040] In this embodiment, the protective housing 1 protects the Chinese medicinal materials transported on the conveyor belt 7. The protective housing 1 consists of two crossbars symmetrically arranged with the conveyor belt 7 as the center line, and a baffle plate on the upper surface of each crossbar. The crossbars in the protective housing 1 are used to connect the support base 2 and the tool holder 5, and to support the tool holder 5, so that the cleaning roller 8 on the tool holder 5 can be located on the upper surface of the conveyor belt 7. At the same time, the two crossbars support the cleaning roller 8, so that when the cleaning roller 8 comes into contact with the segmented, blocky, or petal-shaped Chinese medicinal materials, the segmented, blocky, or petal-shaped Chinese medicinal materials are driven to rotate by the conveyor belt 7. When the cleaning roller 8 rotates, it cleans impurities from the segmented, blocky, or petal-shaped Chinese medicinal materials during the transportation process.

[0041] In addition, a baffle plate extending toward the conveyor belt 7 is provided on the upper surface of the crossbar, and a cleaning roller 8 is disposed below the baffle plate. In this embodiment, the crossbar and the baffle plate are integrally formed. The baffle plate designed in this embodiment is used to block the splashing of medicinal debris when cutting Chinese medicinal materials and can also block the splashing of Chinese medicinal materials that are cut to a smaller size. At the same time, the cleaning roller 8 disposed below the baffle plate can clean the Chinese medicinal materials after cutting.

[0042] Meanwhile, in this embodiment, the cleaning roller 8 is rotatably connected to the crossbar as follows: a rotating shaft is loosely inserted through the cleaning roller 8 along its axial direction. One end of the rotating shaft is inserted into and fixedly connected to the corresponding crossbar, and the other end of the rotating shaft is inserted into and fixedly connected to the corresponding crossbar. In this embodiment, the rotating shaft supports the cleaning roller 8. Since the cleaning roller 8 is loosely fitted on the rotating shaft, during the conveyor belt 7, the segmented, blocky, or petal-shaped Chinese medicine will push the cleaning roller 8 to rotate around the rotating shaft, thus cleaning the segmented, blocky, or petal-shaped Chinese medicine while the cleaning roller 8 rotates. The two ends of the rotating shaft are respectively inserted into and fixedly connected to the corresponding crossbars, thereby limiting the position of the rotating shaft and thus limiting the position of the cleaning roller 8.

[0043] See Figure 1As shown, in this embodiment, the support base 2 is rotatably connected to the driving wheel and the driven wheel at both ends along the conveying direction. The conveyor belt 7 is wound between the driving wheel and the driven wheel. The driving wheel is coaxially connected to the drive motor 4 mounted on the support base 2. The drive motor 4 is installed inside the support base 2. A support plate 11 fixed on the support base 2 is provided between the driving wheel and the driven wheel. The upper and lower surfaces of the support plate 11 are in contact with the conveyor belt 7. The support plate 11 is located directly below the tool holder 5. Therefore, the conveyor belt 7 is wound around the upper and lower surfaces of the support plate 11, which facilitates the upper and lower surfaces of the support plate 11 to contact the conveyor belt 7, thereby providing support for the cutting of the Chinese medicinal materials conveyed on the conveyor belt 7.

[0044] In this embodiment, when the output shaft of the drive motor 4, which is coaxially connected to the drive wheel, is coaxially connected to the drive wheel, the drive motor 4 is started. The output shaft of the drive motor 4 rotates, causing the drive wheel to rotate. The rotation of the drive wheel causes the conveyor belt 7 to rotate and move, thereby causing the driven wheel to rotate. At the same time, the support plate 11 set between the drive wheel and the driven wheel can contact the conveyor belt 7. This ensures that the Chinese medicinal materials move along the conveying direction when the conveyor belt 7 moves. During the movement of the Chinese medicinal materials, the upper surface of the support plate 11 can support the conveyor belt 7. At the same time, when the cutting blade 9 in the tool holder 5 set directly above the support plate 11 cuts the Chinese medicinal materials, the support plate 11 supports the cutting force of the cutting blade 9. This ensures that the Chinese medicinal materials can be cut into segmented, block-shaped, or petal-shaped Chinese medicinal materials.

[0045] See Figure 2 and Figure 3 As shown, in this embodiment, the driving component includes a servo motor 6 disposed on the top of the tool holder 5. The output shaft of the servo motor 6 extends toward the cutting blade 9. The output shaft of the servo motor 6 is fixedly connected to the upper side of the cutting blade 9. Two guide pillars 10 are symmetrically arranged inside the tool holder 5 with the output shaft of the servo motor 6 as the center line. The two sides of the cutting blade 9 pass through the corresponding guide pillars 10 and can move up and down along the height direction of the tool holder 5.

[0046] In this embodiment, the servo motor 6 drives the cutting blade 9 to move up and down along the height direction of the tool holder 5 via the output shaft of the servo motor 6. During the downward movement along the height direction of the tool holder 5, the cutting blade 9 cuts the Chinese medicinal materials on the conveyor belt 7 into segmented, block-shaped, or petal-shaped Chinese medicinal materials. During the upward and downward movement of the cutting blade 9 along the height direction of the tool holder 5, the guide posts 10 set on both sides of the tool holder 5 allow the cutting blade 9 to pass through and guide the upward and downward movement of the cutting blade 9.

[0047] The system uses a drive motor 4 to drive a conveyor belt 7, which in turn moves the medicinal herbs along the conveying direction to directly below the cutting blade 9. A servo motor 6 then drives the cutting blade 9 to cut the medicinal herbs into segments, blocks, or petals along the height direction. This eliminates the need for workers to hold the herbs by hand during cutting, reducing the risk of cuts or scratches. Furthermore, the cleaning roller 8 designed in this invention cleans the cut surfaces of the segmented, block, or petal-shaped medicinal herbs, significantly reducing the amount of impurities adhering to these surfaces.

[0048] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
