Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a medicinal material grinding equipment. Background Technology

[0002] Before use, medicinal materials usually need to be pre-treated according to the requirements of subsequent processing or application. Among them, grinding is one of the common steps in the processing of medicinal materials. By grinding medicinal materials, block, flake, or granular materials can be transformed into smaller particles or powders, which facilitates subsequent mixing, extraction, formulation, or direct use.

[0003] In related technologies, the grinding of medicinal materials usually involves feeding the medicinal materials to be processed into the grinding device from the feeding position, where the grinding mechanism crushes or grinds the medicinal materials, and then discharging the ground medicinal materials through the discharge port.

[0004] However, in practical applications, the same medicinal material often requires different mesh sizes depending on the formulation, processing technology, or usage scenario. For example, the same medicinal material may require a larger particle size in one formulation, while a smaller particle size may be needed in another. To meet these different mesh size requirements, different grinding devices or multiple processing steps are typically required. This increases equipment costs and prolongs the processing time and cycle, thus hindering the efficiency and flexibility of medicinal material processing. Summary of the Invention

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this specification as detailed in the appended claims.

[0033] The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” as used in this specification and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0034] It should be understood that although the terms first, second, third, etc., may be used in this specification to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this specification, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0035] In related technologies, medicinal materials are usually ground first. However, for the same medicinal material, different formulations often require different particle size or mesh counts. Therefore, after the initial grinding, the medicinal material usually needs to be sieved again to meet the corresponding usage requirements. This also means that when the same medicinal material requires different specifications, different sieving equipment and different sieving methods are often needed, which can easily lead to increased equipment costs, cumbersome operating procedures, and longer processing cycles.

[0036] Based on this, see Figures 1 to 12 This application provides a medicinal material grinding device.

[0037] The herbal grinding device includes a housing 1, a grinding mechanism 2, and a sieving mechanism 3. The housing 1 includes a feed inlet 11 and a discharge outlet 12. The grinding mechanism 2 is located inside the housing 1 and between the feed inlet 11 and the discharge outlet 12, and is used to grind the herbal materials that enter through the feed inlet 11. The sieving mechanism 3 includes a sieving box 31, a first sieving component 32, and a second sieving component 33. The sieving box 31 is connected to the discharge outlet 12. The first sieving component 32 is movably located inside the sieving box 31 and is used to perform initial sieving of the ground herbal materials. The second sieving component 33 is located inside the sieving box 31 and directly below the first sieving component 32, and is used to selectively perform secondary sieving of the herbal materials that have been initially sieved by the first sieving component 32.

[0038] When the herbal grinding device is working, the herbs enter the equipment housing 1 through the feeding port 11 and are ground under the action of the grinding mechanism 2. After grinding, the herbs enter the screening box 31 and are first screened by the first screening component 32. If further adjustment of the particle size or mesh size is required, the second screening component 33 screens the herbs again. This setup allows for the grinding, initial screening, and rescreening of herbs within the same equipment, which helps reduce manual screening processes, lowers the equipment configuration costs for processing herbs of different specifications, and improves the efficiency of herbal processing.

[0039] The meaning of the second screening component 33 selectively screening the medicinal materials after the initial screening by the first screening component 32 can be understood as follows: when the medicinal materials have met the corresponding particle size or mesh requirements after the initial screening by the first screening component 32, the medicinal materials do not need to enter the second screening component 33 for screening; when the medicinal materials have not met the predetermined requirements after the initial screening by the first screening component 32, they enter the second screening component 33 for further screening.

[0040] It should be noted that the grinding mechanism 2 can be a conventional grinding structure in related technologies, which will not be elaborated upon in this application.

[0041] As an example, the grinding mechanism 2 may include two grinding rollers arranged opposite each other, forming a grinding space between the two grinding rollers for the medicinal materials to pass through, and a power source for driving the two grinding rollers to rotate; after the medicinal materials enter the grinding space, they are ground under the relative rotation of the two grinding rollers. Of course, the grinding mechanism 2 is not limited to the above form. In other embodiments, the grinding mechanism 2 may also adopt a grinding disc type, blade type, hammer type, or other structure that can realize the function of grinding medicinal materials.

[0042] Furthermore, the sieving chamber 31 includes a chamber body and a door disposed on the chamber body, the door being openable or closed relative to the chamber body. During the operation of the herbal grinding device, the door is closed during the herbal sieving process, allowing the herbal materials to undergo initial and / or secondary sieving within the sieving chamber 31. After sieving, the door is opened to allow the sieving herbal materials to be removed, collected, or the interior of the sieving chamber 31 to be cleaned.

[0043] This design reduces the spillage of medicinal materials during the sieving process, which helps ensure the stability of the sieving process. At the same time, opening the door after sieving makes it easier for operators to retrieve and maintain the materials, thereby improving the ease of use of the medicinal material grinding device.

[0044] Furthermore, the herbal grinding device also includes a dust extraction mechanism connected to the feeding port 11, used to extract and treat the dust generated during the feeding process of the herbal materials. In some embodiments, the dust extraction mechanism can also be connected to the sieving box 31 to extract and treat the dust generated during the sieving process of the herbal materials.

[0045] With this configuration, the dust collection mechanism can not only collect dust during the feeding process and improve the working environment of the feeding area, but also simultaneously suck up the dust generated inside the screening box 31, thereby reducing dust escape, which is conducive to keeping the inside and surrounding environment of the device clean and improving the safety and environmental protection of the medicinal material processing process.

[0046] In some embodiments of this application, the first screening component 32 includes a first screening turntable 321, a plurality of first screening cylinders 322, and a plurality of first receiving cylinders 323. The first screening turntable 321 is rotatably disposed within the screening box 31, and a plurality of first through holes 3211 extending along its thickness direction are constructed on the first screening turntable 321; the plurality of first screening cylinders 322 are respectively disposed on the first side of the first screening turntable 321 and are correspondingly connected to the plurality of first through holes 3211; the plurality of first receiving cylinders 323 are respectively disposed on the second side of the first screening turntable 321 and are correspondingly disposed to the plurality of first screening cylinders 322, wherein the first side and the second side are disposed opposite to each other.

[0047] When the herbal grinding device is working, the ground herbs can enter the first sieving cylinder 322 and undergo initial sieving under the sieving action of the first sieving cylinder 322. The herbs after initial sieving can enter the first receiving cylinder 323, which is connected to the corresponding first sieving cylinder 322, for collection. By setting up the first sieving turntable 321, the first sieving cylinder 322, and the first receiving cylinder 323, not only can the initial sieving and classified collection of herbs be realized, but it is also convenient to switch between different sieving positions in coordination with the rotation of the first sieving turntable 321, thereby improving the continuity and convenience of herbal sieving processing.

[0048] As an example, four first screening cylinders 322 can be set, and four corresponding first storage cylinders 323 can be set. It should be noted that the number of first screening cylinders 322 and first storage cylinders 323 is not limited to four. In other embodiments, two, three, five or more can be set according to actual screening needs, as long as the initial screening and corresponding storage of medicinal materials can be achieved.

[0049] In some embodiments of this application, each of the plurality of first screening cylinders 322 includes a first cylinder body 3221 and a first filter screen 3222 disposed within the first cylinder body 3221, and the apertures of the first filter screens 3222 in the plurality of different first screening cylinders 322 are different from each other. By providing first filter screens 3222 with different apertures in different first screening cylinders 322, the first screening assembly 32 can be made to form different screening specifications in the initial screening stage.

[0050] With this setup, different first screening cylinders 322 can screen medicinal materials with different particle sizes or different mesh counts, thereby enabling the medicinal materials to be graded in the initial screening stage and facilitating the separate storage of medicinal materials of different specifications in the subsequent process, which helps to improve the targeting of medicinal material screening and processing efficiency.

[0051] As an example, the first sieving component 32 may include four first sieving cylinders 322, and correspondingly four first receiving cylinders 323; wherein the aperture of the first filter screens 3222 in the four first sieving cylinders 322 may correspond to 300 mesh, 400 mesh, 500 mesh, and 600 mesh, respectively, and the four first receiving cylinders 323 are respectively used to receive the medicinal materials after being sieved by the corresponding first sieving cylinder 322. In this way, the same medicinal material can be formed into medicinal material particles or powders of various mesh sizes in the initial sieving stage, thereby better meeting the differentiated requirements for medicinal material specifications under different formulations.

[0052] In some embodiments, the pore size of the first filter screens 3222 in the multiple first screening cylinders 322 can also be the same. In this way, the processing time for medicinal materials with the same pore size can be increased, so that the medicinal materials can be more fully ground and screened at the corresponding screening specifications; at the same time, the first filter screens 3222 with different pore sizes can also be replaced as needed to flexibly adjust the screening specifications of the first screening assembly 32.

[0053] Understandably, during the initial screening of medicinal materials, taking 500-mesh materials as an example, the first receiving cylinder 323 may contain not only materials that meet the 500-mesh requirement, but also materials that do not meet the target mesh size requirements, such as 400-mesh and 300-mesh materials. Thus, the mixing of materials of different mesh sizes may not directly meet the needs of the corresponding formula or processing stage. Furthermore, even if some materials can still be used, the mixture of sizes can easily affect the value of the materials and processing efficiency. Therefore, by setting up a second screening component 33, the materials after the initial screening can be further screened, thereby reducing the impact of mixing materials of different mesh sizes.

[0054] It should be noted that the main difference between the first screening cylinder 322 and the first storage cylinder 323 is that the first screening cylinder 322 is used for the initial screening of medicinal materials, and a first filter screen 3222 is provided at its bottom and / or other positions; while the first storage cylinder 323 is mainly used for storing the medicinal materials after the initial screening, and the first storage cylinder 323 can be a solid cylinder without a filter screen.

[0055] In some embodiments, the first sieving cylinder 322 can be connected to the first sieving turntable 321 via a snap-fit ​​connection, magnetic connection, or other detachable connection method, and the first receiving cylinder 323 can also be connected to the first sieving turntable 321 via a snap-fit ​​connection, magnetic connection, or other detachable connection method. This arrangement not only facilitates the removal of the medicinal materials after the initial sieving but also facilitates the disassembly and replacement of the first sieving cylinder 322 and / or the first receiving cylinder 323 according to actual sieving needs, thereby improving the flexibility of the medicinal material grinding device.

[0056] In some embodiments of this application, the second sieving assembly 33 includes a second sieving turntable 331, a plurality of second sieving cylinders 332, and a plurality of second receiving cylinders 333. The second sieving turntable 331 is fixedly disposed inside the sieving box 31 and located directly below the first sieving turntable 321. The second sieving turntable 331 has a plurality of second through holes 3311 extending along its thickness direction. The plurality of second sieving cylinders 332 are respectively disposed on the first side of the second sieving turntable and are correspondingly connected to the plurality of second through holes 3311. The plurality of second receiving cylinders 333 are respectively disposed on the second side of the second sieving turntable 331 and are correspondingly disposed to the plurality of second sieving cylinders 332. The first receiving cylinder 323 has an openable cap 3232 at one end near the second sieving turntable 331, so that when the first receiving cylinder 323 is opposite to the second sieving cylinder 332, the medicinal material in the first receiving cylinder 323 enters the corresponding second sieving cylinder 332.

[0057] The second sieving disc 331 has its first and second sides arranged opposite to each other. This can be understood as follows: the second sieving cylinder 332 is located on the side of the second sieving disc 331 facing the first sieving disc 321 to receive the medicinal materials falling from the first receiving cylinder 323; the second receiving cylinder 333 is located on the side of the second sieving disc 331 away from the first sieving disc 321 to collect the medicinal materials after being sieved again by the second sieving cylinder 332. Through this arrangement, the medicinal materials can enter the corresponding second receiving cylinder 333 from the second sieving cylinder 332, thereby achieving graded collection after re-sieving.

[0058] When the herbal grinding device is working, the herbs that have undergone initial sieving by the first sieving component 32 first enter the corresponding first receiving cylinder 323. When the corresponding first receiving cylinder 323 rotates to be opposite the second sieving cylinder 332, the cover 3232 opens, and the herbs in the first receiving cylinder 323 enter the corresponding second sieving cylinder 332 for further sieving. The herbs that have undergone further sieving then enter the corresponding second receiving cylinder 333. This arrangement allows for further subdivision of the herbs after initial sieving within the same device, thereby reducing the mixing of herbs with different mesh sizes, improving the sieving accuracy of the herbs, and contributing to improved processing quality and efficiency.

[0059] In some embodiments of this application, each of the plurality of second sieving cylinders 332 includes a second cylinder body 3321 and a second filter screen 3322 disposed on the second cylinder body 3321, and the pore sizes of the second filter screens 3322 in the plurality of second sieving cylinders 332 are different from each other. By providing second filter screens 3322 with different pore sizes on different second sieving cylinders 332, the second sieving assembly 33 can further classify and sieve the medicinal materials after the initial sieving.

[0060] With this configuration, the second screening component 33 can further distinguish between medicinal materials of different mesh sizes that may still be mixed after the initial screening, thereby reducing the problem of limited use or value loss caused by the mixing of medicinal materials of different specifications. This is conducive to improving the screening accuracy of medicinal materials and improving the processing efficiency of medicinal materials while meeting the needs of different formulations.

[0061] It should be noted that the main difference between the second screening cylinder 332 and the second storage cylinder 333 is that the second screening cylinder 332 is used to screen the medicinal materials again, and a second filter screen 3322 is provided at its bottom and / or other positions; while the second storage cylinder 333 is mainly used to store the medicinal materials after being screened again, and the second storage cylinder 333 can be a solid cylinder without a filter screen.

[0062] In some embodiments, the second sieving cylinder 332 can be connected to the second sieving turntable 331 via a snap-fit ​​connection, magnetic connection, or other detachable connection method. Similarly, the second storage cylinder 333 can also be connected to the second sieving turntable 331 via a snap-fit ​​connection, magnetic connection, or other detachable connection method. This arrangement not only facilitates the removal of the re-sieving medicinal materials but also allows for the disassembly and replacement of the second sieving cylinder 332 and / or the second storage cylinder 333 according to actual sieving needs, thereby improving the flexibility of the medicinal material grinding device.

[0063] As an example, the first screening turntable 321 can be equipped with four first screening cylinders 322 and four first receiving cylinders 323, and the first filter screens 3222 in the four first screening cylinders 322 can correspond to 300 mesh, 400 mesh, 500 mesh and 600 mesh respectively; the second screening turntable 331 can be equipped with three second screening cylinders 332 and three second receiving cylinders 333, and the second filter screens 3322 in the three second screening cylinders 332 can correspond to 300 mesh, 400 mesh and 500 mesh respectively. For example, when medicinal materials enter the first receiving cylinder 323 corresponding to 600 mesh after initial screening by the first screening component 32, the materials in the first receiving cylinder 323 may contain not only those meeting the 600 mesh requirement, but also those of 300 mesh, 400 mesh, and 500 mesh. At this point, a second screening by the second screening component 33 can further separate these materials into different specifications such as 300 mesh, 400 mesh, and 500 mesh, allowing for separate collection and utilization. In this way, while meeting the mesh size requirements of different formulations, it also reduces the value loss caused by mixing different specifications of medicinal materials, thus maximizing the efficiency of medicinal material processing.

[0064] In some embodiments of this application, the herbal grinding device further includes a lever 8 and a control mechanism 4 for controlling the opening or closing of the cap 3232. Each of the plurality of first receiving cylinders 323 includes a third cylinder 3231 and a cap 3232, the cap 3232 being openable and closable at one end of the third cylinder 3231 near the second sieving turntable 331; the control mechanism 4 includes a first electromagnet 41 and a second electromagnet 42, the first electromagnet 41 being disposed on the third cylinder 3231 and the second electromagnet 42 being disposed on the cap 3232. It is understood that the ends of the first electromagnet 41 and the second electromagnet 42 that are close to each other can exhibit different magnetic pole states under different operating conditions: when the cap 3232 needs to be closed, the ends of the first electromagnet 41 and the second electromagnet 42 that are close to each other are opposite in polarity, so that they form an attraction between them; when the cap 3232 needs to be opened, the ends of the first electromagnet 41 and the second electromagnet 42 that are close to each other are like in polarity, so that they form a repulsion between them. The lever 8 is located on the second screening turntable 331 and on the movement path of the cover 3232. It is used to contact the cover 3232 after the cover 3232 is opened and to lift the cover 3232 so that the cover 3232 can be closed again under the action of the control mechanism 4.

[0065] When the herbal grinding device is working, when the first receiving cylinder 323 rotates to a position opposite to the corresponding second sieving cylinder 332, the ends of the first electromagnet 41 and the second electromagnet 42 that are close to each other are made to be of the same polarity. The magnetic repulsion between them pushes the cap 3232 open relative to the third cylinder 3231, so that the herbs in the first receiving cylinder 323 can fall into the corresponding second sieving cylinder 332 for further sieving. After the feeding is completed, the first sieving turntable 321 continues to rotate. The cap 3232, which is in the open state, moves together with the first receiving cylinder 323 and comes into contact with the lever 8. The lever 8 lifts the cap 3232, causing it to swing back toward the third cylinder 3231, and the second electromagnet 42 gradually moves closer to the first electromagnet 41. When the second electromagnet 42 moves to the predetermined position, the ends of the first electromagnet 41 and the second electromagnet 42 that are close to each other are made to be of opposite polarity, so that the cap 3232 is attracted to the closed position by the magnetic attraction between them. Thus, by using the combined method of "opening the cover by repulsion of like charges, lifting and resetting by lever 8, and closing the cover by adsorption of opposite charges", the first receiving cylinder 323 can not only open automatically when aligned with the second screening cylinder 332, but also automatically return to the closed state after the material is discharged. This facilitates the first receiving cylinder 323 to enter the next round of screening and helps to improve the automation level of the screening process and the stability of the opening and closing of the cover 3232.

[0066] In some embodiments, the height of the lever 8 can be set according to the opening angle of the cover 3232, the attraction distance between the first electromagnet 41 and the second electromagnet 42, and the structural dimensions of the third cylinder 3231, so that after contacting the cover 3232, the lever 8 can lift the cover 3232 to a position that facilitates the re-attraction of the two electromagnets. As an example, the height of the lever 8 can allow the cover 3232 to be lifted after contact with it until the distance between the second electromagnet 42 and the first electromagnet 41 is reduced to 1mm to 4mm, such as 1.5mm, 2mm, 3mm, or 3.5mm; or, the height of the lever 8 can allow the cover 3232 to swing back 20% to 50% relative to the fully open position, such as about 30% or 40%, so that the two electromagnets can smoothly switch from a repulsive state to an attractive state. This setting can ensure that the cover 3232 is effectively lifted and reliably closed after the material is unloaded, and there is no need to set up an additional large-stroke drive structure, so it usually does not significantly increase the overall volume and floor space of the grinding device.

[0067] In some embodiments of this application, the herbal grinding device further includes a rotating mechanism 5 for driving the first sieving turntable 321 to rotate. The rotating mechanism 5 includes a rotating support 51 and a rotating motor 52. The rotating support 51 is mounted on the second sieving turntable 331, and the rotating motor 52 is mounted on the rotating support 51. The output shaft of the rotating motor 52 is connected to the first sieving turntable 321 via a transmission connection. When the herbal grinding device is working, the rotating motor 52 outputs power and drives the first sieving turntable 321 to rotate relative to the second sieving turntable 331 via its output shaft. This allows different first sieving cylinders 322 to sequentially switch to positions corresponding to the discharge port 12 for initial sieving, or different first receiving cylinders 323 to sequentially switch to positions opposite to the corresponding second sieving cylinders 332 for secondary sieving. Thus, by setting the rotating mechanism 5, the first sieving turntable 321 can be actively rotated, facilitating switching between different sieving and unloading stations, thereby improving the continuity and automation of the herbal sieving process.

[0068] In some embodiments, the herbal grinding device may further include an adjustment component 53, which is used to adjust the rotation state of the first sieving turntable 321 so that the rotation of the first sieving turntable 321 corresponds to the herbal material feeding process. It is understood that if the first sieving turntable 321 rotates continuously or its rotation position is inaccurate, the herbal material output from the outlet 12 may fall at a non-target position on the first sieving turntable 321, such as between adjacent first sieving cylinders 322, on the surface of the first sieving turntable 321, or into a non-corresponding first sieving cylinder 322, thereby causing herbal material waste or affecting the sieving accuracy. Therefore, by setting the adjustment component 53, the first sieving turntable 321 can be kept at a predetermined position or rotated at a predetermined rhythm, so that the herbal material output from the outlet 12 accurately enters the target first sieving cylinder 322, thereby helping to reduce herbal material waste and improve the accuracy and stability of the initial sieving.

[0069] As an example, the adjustment component 53 may include a position detection element and a control element. The position detection element detects the current position of the first sieving turntable 321, and the control element is electrically connected to the position detection element and the rotation motor 52. The position detection element may include, for example, an indicator on the first sieving turntable 321 and a sensor on the first sieving turntable 321 or the rotating support 51. The sensor may be a photoelectric sensor, a magnetic induction sensor, or a proximity sensor. When the herbal grinding device is working, the position detection element detects the rotation position of the first sieving turntable 321 in real time. When the target first sieving cylinder 322 is detected to have rotated to the position corresponding to the discharge port 12, the control element controls the rotation motor 52 to decelerate or stop, so that the herbal material falls from the discharge port 12 into the target first sieving cylinder 322. After the corresponding material is discharged, the control element controls the rotation motor 52 to continue rotating, so that the next first sieving cylinder 322 switches to the position corresponding to the discharge port 12. In this way, intermittent or fixed-point rotation of the first sieving turntable 321 can be achieved, thereby matching the rotation process with the material discharge process.

[0070] It is understandable that when the medicinal materials fall onto the first filter screen 3222, the particles tend to accumulate there due to factors such as the shape of the medicinal materials themselves, particle moisture content, fiber entanglement, and prolonged continuous sieving, leading to clogging of the first filter screen 3222. Once the first filter screen 3222 becomes clogged, it not only affects the efficiency of the medicinal materials passing through it but may also lead to a deterioration in the sieving effect of medicinal materials of different specifications, thus affecting the sieving accuracy. Therefore, in some embodiments, the medicinal material grinding device further includes a striking mechanism 6 for striking the multiple first sieving cylinders 322.

[0071] In some embodiments of this application, the striking mechanism 6 includes a driving component 61 and a plurality of striking components 62, which are correspondingly arranged with a plurality of first screening cylinders 322. Each striking component 62 includes a striking bracket 621, a striking rod 622, and a return spring 623. The plurality of striking brackets 621 are respectively disposed on the first screening turntable 321 and correspondingly arranged with the corresponding first screening cylinder 322. The plurality of striking rods 622 are slidably connected to the corresponding striking brackets 621 and are capable of contacting the corresponding first screening cylinder 322. The plurality of return springs 623 are respectively sleeved on the corresponding striking rods 622 and are configured to drive the striking rods 622 to return to their original position after the striking rods 622 move away from the corresponding first screening cylinder 322 (specifically, after the striking rods 622 move toward the first screening cylinder 322 and contact the first screening cylinder 322, the striking rods 622 apply force to the first screening cylinder 322). The striking action occurs during this process. The return spring 623 is in an elastic deformation state to store elastic potential energy. After the striking action is completed, the return spring 623 releases the elastic potential energy and contracts, driving the striking rod 622 to return to its initial position away from the first screening cylinder 322, thus preparing it for the next striking action. The drive assembly 61 is connected between the output shaft of the rotating motor 52 and the multiple striking rods 622. It is configured to drive the multiple striking rods 622 to move together when the output shaft of the rotating motor 52 rotates, so that the multiple striking rods 622 strike the corresponding first screening cylinder 322. The direction of movement of the striking rod 622 can be intersected with the axial direction of the corresponding first screening cylinder 322, for example, vertically, inclined, or approximately vertically, so that the striking rod 622 can reciprocate in a direction approaching or away from the first screening cylinder 322 and strike it.

[0072] When the herbal grinding device is working, the rotating motor 52 drives the first sieving turntable 321 to rotate, and also drives multiple striking rods 622 to move through the drive assembly 61. When the striking rods 622 move toward the corresponding first sieving cylinder 322, they contact and strike the first sieving cylinder 322, causing the herbal particles attached to the first filter screen 3222 to loosen or detach. After the striking is completed, the return spring 623 drives the striking rods 622 to return to their original position for the next strike. This configuration allows for continuous or intermittent striking of the first sieving cylinder 3222, thereby reducing the possibility of clogging the first filter screen 3222, maintaining good permeability of the first filter screen 3222, and thus improving the efficiency and accuracy of herbal sieving.

[0073] In some embodiments of this application, the driving assembly 61 includes multiple first connecting rods 611, multiple second connecting rods 612, multiple driving turntables 613, and a driven member 614. The multiple driving turntables 613 are rotatably connected to the first screening turntables 321, and the driven member 614 is connected between the output shaft of the rotary motor 52 and the multiple driving turntables 613, for transmitting the rotation of the rotary motor 52 to the multiple driving turntables 613. One end of each of the multiple first connecting rods 611 is rotatably connected to its corresponding driving turntable 613, one end of each of the multiple second connecting rods 612 is rotatably connected to the other end of its corresponding first connecting rod 611, and the ends of the multiple second connecting rods 612 away from their corresponding first connecting rods 611 are rotatably connected to their corresponding striking rods 622. Through this arrangement, the rotation output by the rotary motor 52 can be transmitted to each striking rod 622 via the driven member 614, the driving turntables 613, the first connecting rods 611, and the second connecting rods 612, thereby forming a coordinated impact on the multiple first screening cylinders 322.

[0074] Understandably, the drive turntable 613 has a first protrusion 6131, and the first connecting rod 611 has a second protrusion 6111, with the first protrusion 6131 and the second protrusion 6111 engaging with each other. The length of the first protrusion 6131 extends radially along the drive turntable 613, and the length of the second protrusion 6111 extends axially along the drive turntable 613. When the drive turntable 613 rotates, the first protrusion 6131 moves synchronously with the drive turntable 613 and contacts the second protrusion 6111 during the movement, thereby driving the second protrusion 6111 to move, and consequently driving the first connecting rod 611 to move.

[0075] With this configuration, the rotation of the turntable 613 can be stably transmitted to the first connecting rod 611 through the cooperation of the first protrusion 6131 and the second protrusion 6111, thereby facilitating the movement of the subsequent striking rod 622 and improving the transmission stability and structural reliability of the striking mechanism.

[0076] When the herbal grinding device is working, the output shaft of the rotating motor 52 rotates, and the driven member 614 transmits power to multiple rotating discs 613. When the multiple rotating discs 613 rotate, they respectively drive the corresponding first connecting rod 611 and second connecting rod 612 to move, thereby causing multiple striking rods 622 to reciprocate and strike the corresponding first sieving cylinder 322. This arrangement allows the first sieving cylinder 322 to be struck while the first sieving disc 321 rotates. On the one hand, this helps to promptly shake off the herbs that are attached to or blocked at the first filter screen 3222, ensuring a smooth sieving process. On the other hand, the rotation and striking can be synchronized, eliminating the need for an additional independent drive source, thus simplifying the overall structure, reducing transmission complexity, and improving the efficiency of herbal sieving and space utilization.

[0077] In some embodiments of this application, the driven member 614 includes a driven bracket 6141, a first gear 6142, a second gear 6143, and multiple transmission gear sets 6144. The driven bracket 6141 is mounted on the first screening turntable 321, the first gear 6142 is mounted on the output shaft of the rotary motor 52, the second gears 6143 are respectively mounted on corresponding drive turntables 613, and the multiple transmission gear sets 6144 are rotatably mounted on the driven bracket 6141 and respectively mesh between the first gear 6142 and the corresponding second gear 6143. Through the above arrangement, the power output by the rotary motor 52 can be transmitted to the corresponding drive turntable 613 via the first gear 6142, the transmission gear sets 6144, and the second gears 6143, thereby providing power support for the movement of the multiple striking rods 622.

[0078] When the herbal grinding device is working, the output shaft of the rotating motor 52 drives the first gear 6142 to rotate. The first gear 6142 drives the corresponding second gear 6143 to rotate through multiple transmission gear sets 6144. The second gear 6143 then drives the corresponding drive disc 613 to rotate, so that multiple first connecting rods 611, multiple second connecting rods 612, and multiple striking rods 622 move in unison, thereby striking multiple first sieving cylinders 322. This arrangement can stably distribute the output power of the rotating motor 52 to multiple drive discs 613 to ensure the synchronization and transmission reliability of multiple striking components 62. On the other hand, it can also allow the rotation of the first sieving disc 321 and the striking of the first sieving cylinder 322 to share the same power source, which helps to reduce additional drive structures, simplify the overall transmission layout, and improve the compactness and space utilization of the device structure.

[0079] In some embodiments, the transmission gear set 6144 includes a first bevel gear 61441 and a second bevel gear 61442. The first bevel gear 61441 is rotatably mounted on the driven bracket 6141 and meshes with the first gear 6142. The second bevel gear 61442 is coaxially connected to the first bevel gear 61441 and meshes with the second gear 6143. When the herbal grinding device is working, the first gear 6142 rotates, firstly driving the first bevel gear 61441 to rotate. The first bevel gear 61441 then drives the corresponding second gear 6143 to rotate through the second bevel gear 61442 coaxially connected to it, thereby transmitting power to the corresponding drive turntable 613. In this way, the cooperation of the first bevel gear 61441 and the second bevel gear 61442 not only facilitates the adjustment of the power transmission direction to adapt to the spatial arrangement relationship between the first gear 6142 and the second gear 6143, but also helps to achieve stable transmission in a relatively compact structural space, thereby improving the arrangement flexibility and transmission efficiency of the driven member 614.

[0080] Furthermore, the herbal grinding device may also include a vibration mechanism 7, which is used to vibrate the second sieving component 33. The second sieving component 33 is used to further sieve the herbs after the initial sieving, resulting in finer particles. The second sieving turntable 331 is fixedly installed inside the sieving box 31, and the second sieving component 33 does not involve position switching during operation. Compared to the striking method, the vibration method has a gentler effect on finer herbs and eliminates the need for a striking-related linkage structure on the second sieving turntable 331. Vibrating the second sieving component 33 through the vibration mechanism 7 loosens the herbs inside the second sieving cylinder 332 and causes them to move downwards, thereby improving the effect of the secondary sieving.

[0081] As an example, the vibration mechanism 7 can be a piezoelectric ceramic plate, which is disposed on the inner wall of the second through hole 3311. When the herbal grinding device is working, when the herbal material falling through the first receiving cylinder 323 enters the second sieving cylinder 332 for further sieving, the piezoelectric ceramic plate is energized to generate vibration, and the vibration is transmitted to the herbal material in the second through hole 3311 and the second sieving cylinder 332, so as to loosen the herbal material particles that are attached, accumulated or stuck at the second filter screen 3322, thereby accelerating the speed at which the herbal material passes through the second filter screen 3322. With this configuration, vibration excitation of the second sieving component 33 can be achieved in a small space, which is beneficial to improving the sieving efficiency and accuracy of the second sieving component 33, and also helps to reduce the problem of insufficient sieving caused by herbal material blockage.

[0082] It should be noted that the vibration mechanism 7 is not limited to piezoelectric ceramic sheets. In other embodiments, the vibration mechanism 7 can also be a vibration motor, an electromagnetic vibrator, an eccentric vibrator, or other structures capable of applying vibration to the second sieving component 33, as long as it can achieve vibration of the second sieving component 33 to assist in the re-sieving of the medicinal materials.
