Description

Technical Field

[0001] This invention relates to the field of medicinal material processing technology, and in particular to a device for removing impurities from Chinese medicinal materials used in the production of prepared slices of Chinese medicinal herbs. Background Technology

[0002] As the main form of clinical application of traditional Chinese medicine, the purification of raw medicinal materials during the production process is a crucial preliminary step to ensure the quality, efficacy, and safety of the processed medicinal materials. During harvesting, drying, storage, and transportation, medicinal materials are prone to adhering to impurities such as soil. If impurities are not thoroughly removed, it will not only reduce the purity of the processed medicinal materials but may also affect the dissolution of active ingredients during subsequent processing and decoction, and may even lead to quality risks due to the introduction of foreign matter by impurities.

[0003] Existing devices mostly rely on single vibration screening or static crushing to remove impurities. For tightly attached sticky impurities such as mud, it is difficult to break them up and peel them off by screen vibration alone. Simple crushing lacks auxiliary vibration excitation, and impurities are easily compacted and still adhere to the surface of the medicinal materials, resulting in incomplete impurity removal. Subsequent secondary cleaning is still required, which increases the complexity of the process. Summary of the Invention

[0015] Preferably, the drive unit includes a drive assembly mounted on the support frame, a mounting box mounted on the support frame, a rotating shaft rotatably mounted on the rotating sleeve and connected to the support shaft, and two gear transmission groups, each located within the mounting box and connected to the output end of the drive assembly; the output ends of the two gear transmission groups are respectively connected to the rotating shaft and the rotating sleeve.

[0016] Preferably, the support assembly is provided in multiple sets, with four in each set, and is evenly arranged in a cross shape inside the rolling roller; the support assembly includes a sliding sleeve rotatably disposed on the support shaft, a sliding rod rotatably disposed on the sliding sleeve and rotatably connected to the rolling roller, and an elastic element disposed inside the sliding sleeve for pushing the sliding rod to move.

[0017] Preferably, both the sliding sleeve and the sliding rod are provided with a rotating connector, which is used to rotate with the rolling roller and the support shaft. The sliding sleeve is provided with a guide groove, and the sliding rod is provided with a guide block, which is slidably embedded in the guide groove.

[0018] Preferably, the striking assembly includes a mounting plate disposed on the sliding rod, a striking rod rotatably disposed at the lower part of the mounting plate, a torsion spring disposed on the mounting plate for driving the striking rod to rotate, and a toggle block rotatably disposed on the striking rod and slidably connected to the sliding sleeve; the sliding sleeve is provided with a guide step, and the toggle block is slidably disposed at the guide step.

[0019] Preferably, the striking rod is provided with a reset torsion spring, one side of the actuating block abuts against the striking rod, and the guide step includes a guide inclined side, a parallel side, a vertical side and a bottom side distributed in sequence.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] In this invention, the base plate supports the mounting seat, which in turn supports the support frame, allowing the support frame to rotate. A motor drives a lead screw to rotate, which in turn drives a push block to rotate. The push block moves a sliding rod, which in turn moves a connecting rod, causing the connecting rod to push the support frame to rotate. This allows the support frame to tilt the screening and crushing components, thus adjusting the tilt angle of the screen cylinder. By adjusting the tilt angle, the feeding speed of the screen cylinder can be controlled. Different tilt angles can be selected according to different medicinal materials. For spherical medicinal materials, the tilt angle needs to be reduced to prevent the materials from falling too quickly due to an excessive tilt angle. For columnar medicinal materials, the tilt angle needs to be increased to prevent the materials from being unable to slide downwards.

[0022] The crushing assembly is driven by a drive unit to rotate within the sieving assembly. The crushing roller is supported by a support assembly, and the crushing roller vibrates by a striking assembly. When the medicinal material enters the sieve cylinder from one end, it gradually moves towards the other end of the sieve cylinder. At the same time, the sieve cylinder continues to rotate, which can prevent the medicinal material from getting stuck. The continuous rotation and vibration of the crushing roller can break up the soil attached to the medicinal material when it comes into contact with it, so that the soil falls onto the sieve cylinder and is sieved down. The medicinal material falls down from the end of the sieve cylinder, thus removing impurities from the medicinal material. Attached Figure Description

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0038] like Figure 1-9 As shown, the present invention proposes a traditional Chinese medicine impurity removal device for the production of traditional Chinese medicine decoction pieces, comprising a frame 1, an adjustment component 2, a screening component 3, a crushing component 4, and a drive unit 5;

[0039] Adjustment component 2 is mounted on frame 1 to drive frame 1 to rotate; screening component 3 is rotatably mounted on frame 1; crushing component 4 is rotatably mounted on frame 1 and located inside screening component 3; drive unit 5 is mounted on frame 1 to drive screening component 3 and crushing component 4 to rotate. Frame 1 includes mounting base 101, multiple base plates 102 disposed at the lower end of mounting base 101, and support frame 103 rotatably mounted on mounting base 101 at one end and connected to screening component 3 and crushing component 4.

[0040] Adjustment component 2 includes multiple connecting rods 201 with one end slidably connected to support frame 103, a slide rod 202 slidably mounted on mounting base 101 and rotatably hinged to the other end of connecting rod 201, a push block 203 rotatably connected to slide rod 202, a lead screw 204 rotatably mounted on mounting base 101 and threadedly connected to push block 203, and a motor 205 mounted on mounting base 101 and connected to lead screw 204 at its output end.

[0041] In this embodiment, the base plate 102 supports the mounting base 101, which in turn supports the support frame 103, allowing the support frame 103 to rotate. The motor 205 drives the lead screw 204 to rotate, which in turn drives the push block 203 to rotate. The push block 203 moves the slide bar 202, which in turn moves the connecting rod 201. This causes the connecting rod 201 to push the support frame 103 to rotate, allowing the support frame 103 to tilt the screening component 3 and the crushing component 4. This allows adjustment of the tilt angle of the sieve cylinder 301. By adjusting the tilt angle, the feeding speed of the sieve cylinder 301 can be controlled. Different tilt angles can be selected according to different medicinal materials. For spherical medicinal materials, the tilt angle needs to be reduced to prevent the materials from falling too quickly due to an excessive tilt angle. For columnar medicinal materials, the tilt angle needs to be increased to prevent the materials from being unable to slide downwards.

[0042] The crushing assembly 4 is driven to rotate within the screening assembly 3 by the drive unit 5. The crushing roller 401 is supported by the support assembly 6. The crushing roller 401 is vibrated by the striking assembly 7. When the medicinal material enters the screen cylinder 301 from one end, it gradually moves towards the other end of the screen cylinder 301. At the same time, the screen cylinder 301 continues to rotate, which can prevent the medicinal material from getting stuck. The continuous rotation and vibration of the crushing roller 401 can break up the soil attached to the medicinal material when it comes into contact with the medicinal material, so that the soil falls into the screen cylinder 301 and is screened down by the screen cylinder 301. The medicinal material falls down from the end of the screen cylinder 301, thus performing the impurity removal operation on the medicinal material.

[0043] like Figure 1-9 As shown, the present invention proposes a traditional Chinese medicine impurity removal device for the production of traditional Chinese medicine decoction pieces. In this embodiment, the sieving component 3 includes a rotating sleeve 303 rotatably mounted on a support frame 103, a support rod 302 mounted on the rotating sleeve 303, and a sieve cylinder 301 mounted on the support rod 302; the sieve cylinder 301 has a frustum conical structure.

[0044] The rolling assembly 4 includes a support shaft 404 rotatably connected to the rotating sleeve 303, a rolling roller 401 sleeved on the support shaft 404, a threaded strip 402 disposed on the rolling roller 401, and a vibrating rod 403 disposed on the inner wall of the rolling roller 401; a support assembly 6 connected to the rolling roller 401 is disposed on the support shaft 404; and a striking assembly 7 connected to the vibrating rod 403 is disposed on the support assembly 6.

[0045] In this embodiment, the drive unit 5 drives the screen cylinder 301 and the pressing roller 401 to rotate. The pressing roller 401 is supported by the support assembly 6, allowing it to move up and down, thus pressing the pressing roller 401 inside the screen cylinder 301. The screen cylinder 301 has a truncated cone structure, meaning the larger the diameter end, the greater the gap between it and the pressing roller 401, which serves as the feed inlet. The smaller diameter end serves as the discharge outlet. When the screen cylinder 301 and the pressing roller 401 are in an inclined state, the rotation of the pressing roller 401 drives the threaded strip 402 to rotate, enabling the threaded strip 402 to... The movement of the medicinal materials and the crushing action of the rollers cause the soil on them to fall onto the sieve cylinder 301 and through the filter holes. The rollers 401 can move up and down, thus preventing the medicinal materials from being crushed due to rigid connections. The position of the rollers 401 can be adaptively adjusted according to the size of the medicinal materials to prevent damage. The vibration and crushing action of the rollers 401, combined with the pushing action of the threaded strips 402, can better break up the soil attached to the medicinal materials. The broken soil falls onto the sieve cylinder 301 and finally falls off.

[0046] like Figure 1-9As shown, the present invention proposes a traditional Chinese medicine impurity removal device for the production of traditional Chinese medicine decoction pieces. In this embodiment, the drive unit 5 includes a drive assembly 501 mounted on a support frame 103, a mounting box 502 mounted on the support frame 103, a rotating shaft 504 rotatably mounted on a rotating sleeve 303 and connected to a support shaft 404, and two gear transmission groups 503, both mounted in the mounting box 502 and both connected to the output end of the drive assembly 501. The output ends of the two gear transmission groups 503 are respectively connected to the rotating shaft 504 and the rotating sleeve 303.

[0047] In this embodiment, the mounting box 502 is used to install and support the gear transmission assembly 503. The output power of the drive assembly 501 is transmitted to the gear transmission assembly 503, which then transmits the power to the rotating shaft 504 and the rotating sleeve 303. This allows the rotating shaft 504 to drive the support shaft 404 to rotate, thereby causing the crushing roller 401 to rotate. The rotating sleeve 303 transmits the power to the support rod 302, which in turn drives the sieve cylinder 301 to rotate. This allows both the sieve cylinder 301 and the crushing roller 401 to rotate at different speeds. As the crushing roller 401 rotates inside the sieve cylinder 301, it vibrates and crushes the soil on the medicinal materials, causing the soil to break and fall off the sieve cylinder 301, thus cleaning and removing impurities from the medicinal materials.

[0048] In this embodiment, the rotation of the crushing roller 401 and the pushing action of the threaded strip 402 enable the medicinal materials to move within the sieve cylinder 301 while being crushed. Due to the differential rotation of the crushing roller 401 and the sieve cylinder 301, the contact between the crushing roller 401 and the medicinal materials is more thorough, which can more effectively break up the soil attached to the medicinal materials. The broken soil is screened out by the filter holes of the sieve cylinder 301, thereby achieving efficient impurity removal. The continuous rotation of the sieve cylinder 301 can prevent the medicinal materials from accumulating or getting stuck in the sieve cylinder, ensuring that the medicinal materials can move smoothly from the feed inlet to the discharge outlet. The differential rotation further enhances this effect, so that the medicinal materials maintain good fluidity throughout the process. The vibration and crushing action of the roller 401, combined with the pushing action of the threaded strip 402, effectively breaks up the dirt on the medicinal materials and causes it to fall off the sieve cylinder 301. Differential rotation further enhances this synergistic effect, allowing the dirt to be removed more quickly and improving the impurity removal efficiency. Because the differential rotation of the sieve cylinder 301 and the roller 401 automatically completes the impurity removal process, the need for manual cleaning is reduced, labor intensity is lowered, and production efficiency is improved. Differential rotation ensures that the medicinal materials are evenly stressed throughout the sieve cylinder 301, avoiding localized over- or under-stressing. This uniform treatment method better protects the quality of the medicinal materials while ensuring consistent impurity removal. Through differential rotation and adaptive adjustment, the roller 401 can adjust the pressure according to the actual condition of the medicinal materials, preventing damage due to excessive compression. This design maximizes the preservation of the integrity of the medicinal materials while ensuring effective impurity removal.

[0049] like Figure 1-9 As shown, the present invention proposes a traditional Chinese medicine impurity removal device for the production of traditional Chinese medicine decoction pieces. In this embodiment, the support component 6 is provided in multiple sets, with four components in each set, and they are evenly arranged in a cross shape inside the rolling roller 401. The support component 6 includes a sliding sleeve 601 rotatably mounted on a support shaft 404, a sliding rod 602 rotatably mounted on the sliding sleeve 601 and rotatably connected to the rolling roller 401, and an elastic element 604 disposed inside the sliding sleeve 601 for pushing the sliding rod 602 to move.

[0050] Both the sliding sleeve 601 and the sliding rod 602 are provided with rotating connecting parts, which are used to rotatably connect with the rolling roller 401 and the support shaft 404. The sliding sleeve 601 is provided with a guide groove, and the sliding rod 602 is provided with a guide block 603, which is slidably embedded in the guide groove.

[0051] In this embodiment, the crushing roller 401 can move up and down, and through the support component 6, it can automatically adjust the contact pressure with the sieve cylinder 301 according to the size of the medicinal material. The differential rotation makes the contact between the crushing roller 401 and the medicinal material more uniform at different positions, avoiding the squeezing and damage of the medicinal material due to rigid connection, thereby protecting the integrity of the medicinal material. This design allows the device to adapt to medicinal materials of different shapes and sizes. Whether it is spherical or columnar medicinal material, the ideal impurity removal effect can be achieved by adjusting the tilt angle of the sieve cylinder 301 and the differential rotation.

[0052] Furthermore, the striking assembly 7 includes a mounting plate 701 disposed on the sliding rod 602, a striking rod 702 rotatably disposed on the lower part of the mounting plate 701, a torsion spring 703 disposed on the mounting plate 701 for driving the striking rod 702 to flip, and a toggle block 704 rotatably disposed on the striking rod 702 and slidably connected to the sliding sleeve 601; the sliding sleeve 601 is provided with a guide step 6011, and the toggle block 704 is slidably disposed at the guide step 6011.

[0053] Furthermore, a reset torsion spring is provided on the striking rod 702, one side of the toggle block 704 abuts against the striking rod 702, and the guide step 6011 includes a guide inclined side, a parallel side, a vertical side and a bottom side distributed in sequence.

[0054] In this embodiment, the support shaft 404 is driven to rotate by the drive unit 5. Under the action of centrifugal force, the support shaft 404 drives the sliding sleeve 601 to slide, the sliding sleeve 601 drives the sliding rod 602 to move, and the sliding rod 602 drives the pressing roller 401 to rotate, so that the pressing roller 401 can rotate inside the screen cylinder 301. Affected by the gravity of the pressing roller 401, the pressing roller 401 will droop and press down on the screen cylinder 301, while the sliding rod 602 slides inside the sliding sleeve 601, thereby providing pressing. The space where the roller 401 hangs down can exert a certain pressure when it comes into contact with the medicinal material, thereby breaking up the soil on the medicinal material and causing the soil to fall off. Through a certain pressure, the soil can be broken up better. The elastic element 604 pushes the sliding rod 602 to move upward, so that the sliding rod 602 and the sliding sleeve 601 can automatically reset, thereby supporting the roller 401. Since the roller 401 is rotating, multiple support components 6 are provided in the circumferential direction of the roller 401.

[0055] By rotating the connecting piece, the sliding sleeve 601 and sliding rod 602 can adaptively adjust their tilt angles while keeping the support shaft 404 in a constant position. This allows the crushing roller 401 to fall onto the sieve cylinder 301, enabling better contact with the medicinal materials and breaking up the dirt on them. When the sliding rod 602 slides towards the sliding sleeve 601, it moves the mounting plate 701. The mounting plate 701 then moves the striking rod 702, causing the actuating block 704 to slide on the guide step 6011. This guide step 6011 guides the actuating block 704, causing it to move up and down. This, in turn, causes the striking rod 702 to rotate back and forth. When the striking rod 702 stores energy through the torsion spring 703, and the actuating block 704 moves towards the lower part of the guide step 6011, the torsion spring 703 releases the stored elastic potential energy. This allows the striking rod 702 to quickly strike the vibrating rod 403, causing the vibrating rod 403 to vibrate. The vibrating rod 403 transmits the vibration to the crushing roller 401, causing the crushing roller 401 to press and vibrate on the medicinal material. This breaks up the dirt on the medicinal material, allowing it to fall off the sieve cylinder 301. In other words, the sliding rod 602 in this embodiment can slide back and forth in the up and down direction, causing the striking rod 403 to rotate and apply an external force to the vibrating rod 403. This allows for the removal of impurities from the medicinal material, quickly removing the dirt carried on it, and facilitating subsequent cleaning and use.

[0056] The sequentially distributed guide sides, parallel sides, vertical sides, and bottom sides guide the actuating block 704 as the sliding rod 602 moves toward the sliding sleeve 601. This allows the actuating block 704 to move from the bottom side to the guide side, and then gradually to the parallel side. When the actuating block 704 reaches the vertical side, it loses support, causing the torsion spring 703 to rotate the striking rod 702. This causes the actuating block 704 to quickly fall onto the bottom side, enabling the striking rod 702 to swing back and forth. The movement of the actuating block 704 also controls the swing amplitude of the striking rod 702, allowing the torsion spring 703 to store energy. When the torsion spring 703 releases its elastic force, it quickly releases its elastic potential energy, rotating the striking rod 702. This causes the striking rod 702 to strike the vibrating rod 403, allowing the threaded strip 402 to transmit vibration. This effectively taps the soil on the medicinal herbs, causing the soil to fall off.

[0057] Each time the actuating block 704 passes through the guide slope, parallel side, vertical side, and bottom edge in a cycle, it can generate relative displacement under the influence of centrifugal force and the gravity of the rolling roller 401. At this time, there is no contact between the striking rod 702 and the vibrating rod 403. Also under the influence of centrifugal force and the gravity of the rolling roller 401, the striking rod 702 can flip and press against the actuating block 704. The striking rod 702 is as close to the actuating block 704 as possible, storing force in the opposite direction for the torsion spring 703. When the actuating block 704 moves upward to reset, that is, when it is small in centrifugal force and almost no influence of the gravity of the rolling roller 401, the striking rod 702 rotates in the opposite direction and moves away from the actuating block 704 when the elastic force of the torsion spring 703 is released, and can strike the vibrating rod 403.

[0058] When the sliding rod 602 moves away from the sliding sleeve 601, the striking rod 702 causes the actuating block 704 to move. The actuating block 704 is guided and flipped by the vertical edge, allowing it to slide on the guide step 6011. When the actuating block 704 moves to the bottom edge again, it is pushed by the return torsion spring, causing it to rotate to a position perpendicular to the striking rod 702. The actuating block 704 then locks onto the striking rod 702, restricting its further rotation. This allows the actuating block 704 to move when the striking rod 702 moves towards the sliding sleeve 601. The working mechanism guides the striking rod 702, causing it to flip and thus enabling the torsion spring 703 to store energy. When the striking rod 702 moves away from the sliding sleeve 601, the actuating block 704 rotates on the striking rod 702 without affecting its upward movement. This allows the striking rod 702 to strike the vibrating rod 403 and generate vibration when the crushing roller 401 rotates. Compared to crushing, this method can better break up the soil, improve the cleaning effect, and clean the soil adhering to the medicinal materials more thoroughly, thus facilitating subsequent cleaning operations.

[0059] In this embodiment, the support assembly 6 (including a sliding sleeve 601, a sliding rod 602, and an elastic element 604) provides stable support for the crushing roller 401, ensuring that the crushing roller 401 can rotate smoothly within the sieve cylinder 301. Through the sliding of the sliding rod 602 within the sliding sleeve 601 and the action of the elastic element 604, the crushing roller 401 can adaptively adjust according to the size and shape of the medicinal materials. This dynamic adjustment capability allows the crushing roller 401 to maintain appropriate pressure when in contact with the medicinal materials, avoiding the squeezing and damage of the medicinal materials due to rigid connection. The striking assembly 7 (including a mounting plate 701, a striking rod 702, a torsion spring 703, and a toggle block 704) transmits vibration to the crushing roller 401 by striking the vibrating rod 403, enabling the crushing roller 401 to vibrate. The vibration can further break up the soil attached to the medicinal materials, making it easier for them to fall out of the filter holes of the sieve cylinder 301, thereby improving the impurity removal effect. The support component 6 provides stable support, allowing the crushing roller 401 to maintain good contact with the medicinal materials. The striking component 7 causes the crushing roller 401 to vibrate by striking the vibrating rod 403, further breaking up the soil on the medicinal materials. This synergistic effect allows the soil to be more thoroughly broken up and removed under the dual action of crushing and vibration of the crushing roller 401. The synergistic effect of the support component 6 and the striking component 7 enables the device to achieve the best impurity removal effect by dynamically adjusting and vibrating when processing different types of medicinal materials. Specifically, after the medicinal materials enter the sieve cylinder 301, the support component 6, through the action of the elastic element 604, enables the crushing roller 401 to adaptively adjust according to the size and shape of the medicinal materials, ensuring that the crushing roller 401 maintains appropriate pressure with the medicinal materials. The striking component 7, through the storage and release of the torsion spring 703, drives the striking rod 702 to strike the vibrating rod 403, causing the crushing roller 401 to vibrate. During the rotation of the crushing roller 401, the threaded strip 402 pushes the medicinal materials to move, and at the same time, combined with the vibration, the soil on the medicinal materials is broken up and falls out of the filter holes of the sieve cylinder 301. This synergistic effect not only improves the impurity removal efficiency, but also protects the quality of the medicinal materials, enabling the device to adapt to the processing needs of different types of medicinal materials.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
