Abstract
Description
Technical Field
[0001] This utility model relates to the field of Chinese medicine grinding equipment, and in particular to a Chinese medicine decoction piece grinding device. Background Technology
[0002] Prepared medicinal herbs are Chinese medicinal materials that have undergone processing according to traditional Chinese medicine theories and methods, and can be directly used in clinical practice. There is no absolute boundary between raw Chinese medicinal materials and prepared medicinal herbs. Prepared medicinal herbs include some sliced Chinese medicinal materials processed at their place of origin, whole raw medicinal materials, and processed or roasted medicinal herbs. The first two categories should be considered as raw Chinese medicinal materials in management, but are understood as prepared medicinal herbs in prescriptions and formulations based on traditional Chinese medicine theories.
[0003] Traditional Chinese medicine (TCM) grinding equipment typically uses stone mills and mortars for grinding, relying solely on manual crushing methods. This process is extremely slow. With a large volume of TCM slices to be ground, precise control of the grinding force and time is difficult to achieve, making it challenging to grind the slices into a uniform fine powder. The grinding results vary significantly between batches, with some producing coarse particles and others fine ones. This affects the quality stability of subsequent TCM preparations, leading to a substantial decrease in work efficiency and hindering timely medication delivery to patients. Furthermore, the inconsistent particle size of the ground TCM slices, without a sieving mechanism, can cause larger particles to clog pipes or feed inlets, interrupting production and requiring machine shutdown for cleaning. This further reduces production efficiency, and the presence of both coarse and fine powder in the product affects the appearance, texture, and stability of the medicine, increasing production time and costs.

[0006] Furthermore, a second sprocket is fixedly connected to the left end of the first connecting rod. The outer side of the first sprocket meshes with the inner front side of the chain, and the outer side of the second sprocket meshes with the inner rear side of the chain. A connecting plate is fixedly connected to the outer side of each roller. A grinding plate is threadedly connected to the outer side wall of each connecting plate. A feed inlet is provided at the top of the outer box, and a first guide box is fixedly connected to the bottom of the discharge box. The outer bottom of the first guide box is connected through to the top of the bottom box.
[0007] Furthermore, a control panel is fixedly connected to the right side wall of the bottom box, a base is fixedly connected to the bottom of the bottom box, and a second flow guide box is fixedly connected to the inner bottom wall of the bottom box.
[0008] Furthermore, a filter plate is provided on the upper side wall of the second flow guide box, and a device box is provided inside the filter plate. A first fixing plate is provided at the bottom of the device box. The bottom wall of the first fixing plate is fixedly connected to the inside of the filter plate, and a second connecting rod is fixedly connected to the upper side wall of the first fixing plate.
[0009] Furthermore, pulleys are fixedly connected to the top ends of the four second connecting rods, a second motor is installed inside the device box, a second fixed plate is rotatably connected inside the device box, and a rotating rod is fixedly connected to the output end of the second motor.
[0010] Furthermore, the bottom end of the rotating rod is fixedly connected to the inside of the upper side wall of the second fixed plate, and the bottom wall of the second fixed plate is fixedly connected with inclined blocks, and the four inclined blocks and four pulleys are correspondingly arranged.
[0011] Furthermore, sleeves are fixedly connected to the bottom wall of the filter plate and the upper side wall of the second flow guide box, and springs are fixedly connected inside each of the upper and lower sleeves.
[0012] Furthermore, the bottom of the second guide box is connected to a discharge pipe, the bottom end of which is connected to the bottom of the bottom box. The left side wall of the filter plate is connected to a conveying pipe, the front side of which is connected to a discharge pipe, and the outer side of the front end of the conveying pipe is connected to the front side of the bottom box.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This utility model, through its outer casing, support plate, first motor, first sprocket, roller, and grinding blade, solves the problem of significantly reduced work efficiency and inability to provide timely medication services to patients due to the instability of subsequent traditional Chinese medicine preparations. The roller rotates inside the outer casing, and during this rotation, the connecting plate fixedly connected to its outer side also rotates. The grinding plate, threaded onto the connecting plate, begins to grind the traditional Chinese medicine pieces placed inside the outer casing. As the roller continues to rotate, the grinding plate continuously shears the traditional Chinese medicine pieces and contacts the concave and convex surfaces of the inner wall of the outer casing through the connecting plate, causing impact and friction that gradually pulverizes and refines the traditional Chinese medicine pieces. This effectively improves work efficiency, especially suitable for grinding large quantities of traditional Chinese medicine pieces, thereby accelerating drug absorption, allowing the drugs to exert their therapeutic effects more quickly, and improving treatment efficacy.
[0015] 2. By incorporating a filter plate, a second motor, inclined blocks, pulleys, springs, and a discharge pipe, this system effectively addresses issues that cause production interruptions, necessitating shutdowns for cleaning, reduced production efficiency, and the presence of both coarse and fine powders in the product, which negatively impacts the appearance, texture, and stability of the medicine. It also reduces downtime due to equipment malfunctions, thus improving overall production efficiency. The output of the second motor drives a rotating rod, causing the second fixed plate, fixed at the bottom of the rod, to rotate inside the device housing. As the second fixed plate rotates, the four inclined blocks at its bottom also move in a circular motion. Since the inclined blocks are correspondingly positioned to contact the pulleys, they exert downward pressure, causing the filter plate to move downwards and compress the springs. This effectively improves the purity of the herbal powder, ensuring drug quality and safety, reducing downtime due to equipment malfunctions, and increasing overall production efficiency.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0028] like Figure 1 - Figure 7The apparatus shown is a traditional Chinese medicine (TCM) grinding device, comprising a base box 1, a discharge box 2 fixedly connected to the upper side wall of the base box 1, and an outer box 3 fixedly connected to the top of the discharge box 2. After the TCM is ground, it falls into the base box 1 through the discharge box 2. Support frames 4 are fixedly connected to both the left and right sides of the outer box 3, and fixtures 5 are fixedly connected to the upper side walls of the two support frames 4. The support frames 4 on the left and right side walls of the outer box 3 provide support and fixation for the fixtures 5 at the top, and the fixtures 5 also support the left and right ends of the first connecting rod 13 to provide stable rotation.
[0029] The inner left and right side walls of the outer box 3 are threaded with support plates 6. The support plates 6 support the rollers 12 on both sides of the inner wall, thereby preventing particles from falling through the gaps on both sides. A chain box 7 is fixedly connected to the left side wall of the outer box 3. The chain box 7 is equipped with a chain 15. By fixing the chain box 7 to the left side wall of the outer box 3, the chain 15 inside is protected from the outside.
[0030] A support plate 8 is fixedly connected to the upper side wall of the base box 1. A first motor 9 is installed on the top of the support plate 8. The support plate 8 fixes the first motor 9 to the top of the base box 1 and provides bottom support for the first motor 9. A connecting shaft 10 is fixedly connected to the output end of the first motor 9. A first sprocket 11 is fixedly connected to the outer left end of the connecting shaft 10. The output end of the first motor 9 drives the connecting shaft 10 to rotate, and the first sprocket 11 fixed to the outer left end of the connecting shaft 10 rotates synchronously.
[0031] Rollers 12 are rotatably connected to the inner walls of the two support plates 6. A first connecting rod 13 is fixedly connected inside the roller 12. The outer sides of the left and right ends of the first connecting rod 13 are rotatably connected to the inside of the two fixtures 5. A second sprocket 14 is fixedly connected to the left end of the first connecting rod 13. The outer side of the first sprocket 11 meshes with the inner front side of the chain 15. The outer side of the second sprocket 14 meshes with the inner rear side of the chain 15. A connecting plate 17 is fixedly connected to the outer side of each roller 12. A grinding plate 16 is threadedly connected to the outer side wall of each connecting plate 17. A feed inlet 18 is opened at the top of the outer box 3. A first guide box 19 is fixedly connected to the bottom of the discharge box 2. The outer bottom of the first guide box 19 is connected through to the top of the bottom box 1. The Chinese herbal medicine pieces that need to be ground are fed into the outer box 3 through the feed inlet 18. After grinding, the powder flows into the discharge box 2 and is guided by the first guide box 19 so that the powder falls accurately onto the filter plate 23 inside the bottom box 1.
[0032] The first sprocket 11 meshes with the chain 15, and the chain 15 drives the second sprocket 14 inside the rear to rotate. The second sprocket 14 is fixed to the left end of the first connecting rod 13. The middle part of the first connecting rod 13 is connected to the outer roller 12. Under the transmission action of the chain 15, the roller 12 begins to rotate inside the outer box 3. During the rotation of the roller 12, the connecting plate 17 fixedly connected to its outer side also rotates. The grinding plate 16 threaded on the connecting plate 17 begins to grind the Chinese herbal medicine pieces put into the outer box 3. As the roller 12 continues to rotate, the connecting plate 16 contacts the concave and convex surfaces of the inner wall of the outer box 3, so that the grinding plate 16 continuously squeezes the Chinese herbal medicine pieces to impact and rub them, so that the Chinese herbal medicine pieces are gradually crushed and refined.
[0033] As described above, the connecting plate 17 can guide and divert the powder, so that when the connecting plate 17 rotates, it can drive the Chinese medicine particles to be evenly distributed on the concave and convex surfaces of the inner wall of the outer box 3, so that the grinding plate 16 can grind the Chinese medicine particles.
[0034] like Figure 1 - Figure 6 As shown, a control panel 20 is fixedly connected to the right side wall of the base box 1. The entire device is controlled through the control panel 20. A base 21 is fixedly connected to the bottom of the base box 1 to support the bottom of the entire device.
[0035] A second flow guide box 22 is fixedly connected to the inner bottom wall of the bottom box 1. A filter plate 23 is provided on the upper side wall of the second flow guide box 22. A device box 24 is provided inside the filter plate 23. The device box 24 is used to protect the device inside from the outside.
[0036] A first fixing plate 25 is provided at the bottom of the device box 24. The bottom wall of the first fixing plate 25 is fixedly connected to the inside of the filter plate 23. The upper side wall of the first fixing plate 25 is fixedly connected to the second connecting rods 30. The top ends of the four second connecting rods 30 are fixedly connected to the pulleys 31. A second motor 26 is provided inside the device box 24. A second fixing plate 28 is rotatably connected inside the device box 24. A rotating rod 27 is fixedly connected to the output end of the second motor 26. The output end of the second motor 26 drives the rotating rod 27 to rotate, thereby causing the second fixing plate 28 fixed at the bottom end of the rotating rod 27 to start rotating inside the device box 24. As the second fixing plate 28 rotates, the inclined block 29 at its bottom also makes a circular motion. Since the inclined block 29 is correspondingly set with the pulleys 31, when the inclined block 29 rotates to contact the pulleys 31, it will apply a downward pressure to the pulleys 31, causing the filter plate 23 to move downward as a whole, thereby compressing the spring 33.
[0037] like Figure 5 - Figure 7 As shown, the bottom end of the rotating rod 27 is fixedly connected to the inside of the upper side wall of the second fixed plate 28. The bottom wall of the second fixed plate 28 is fixedly connected with inclined blocks 29. The four inclined blocks 29 and the four pulleys 31 are correspondingly arranged. When the inclined blocks 29 continue to rotate away from the pulleys 31, the spring 33 will push the filter plate 23 to move upward due to its own elastic restoring force. This cycle repeats, causing the device box 24 to vibrate up and down. The frequency of the vibration is transmitted to the filter plate 23 through the first fixed plate 25, causing the filter plate 23 to vibrate as well.
[0038] Sleeves 32 are fixedly connected to the bottom wall of the filter plate 23 and the upper side wall of the second guide box 22. Springs 33 are fixedly connected inside each pair of upper and lower sleeves 32. The springs 33 are supported on the outside by each upper and lower sleeve 32. The bottom of the second guide box 22 is connected to the discharge pipe 34. After filtration, qualified powder will fall into the second guide box 22 through the holes and grooves of the filter plate 23. The second guide box 22 guides the powder so that the qualified powder is discharged through the discharge pipe 34.
[0039] The bottom end of the discharge pipe 34 is connected to the bottom of the bottom box 1. The left side wall of the filter plate 23 is connected to the conveying pipe 35. The front side of the conveying pipe 35 is connected to the discharge pipe 36. The outer side of the front end of the conveying pipe 35 is connected to the front side of the bottom box 1. Larger particles intercepted by the filter plate 23 will be moved to the left side of the filter plate 23 by the vibration frequency and enter the interior of the conveying pipe 35. The front side of the conveying pipe 35 collects the unqualified powder particles and puts them back into the interior of the outer box 3 for secondary grinding to ensure that the particle size of the powder is consistent.
[0040] It should be noted that this utility model is a Chinese herbal medicine grinding device. First, the first motor 9, control panel 20, and second motor 26 are connected to an external power source to supply power to the device.
[0041] First, the Chinese herbal medicine slices to be ground are fed into the outer casing 3 through the feed inlet 18. The first motor 9 is started, which drives the connecting shaft 10 to rotate. The first sprocket 11 fixed to the outer side of the left end of the connecting shaft 10 rotates synchronously.
[0042] Because the first sprocket 11 meshes with the front interior of the chain 15, and the rear interior of the chain 15 meshes with the second sprocket 14, and the second sprocket 14 is fixed to the left end of the first connecting rod 13, the first connecting rod 13 is rotatably connected inside the two retainers 5 to support the left and right ends of the first connecting rod 13, thus providing a stable rotation effect. Its middle part is connected to the outer roller 12, so under the transmission action of the chain 15, the roller 12 begins to rotate inside the outer casing 3.
[0043] As the roller 12 rotates, the connecting plate 17 fixedly connected to its outer side also rotates. The grinding plate 16 threaded on the connecting plate 17 begins to grind the Chinese herbal medicine pieces put into the outer box 3. As the roller 12 continues to rotate, the connecting plate 16 contacts the concave and convex surfaces of the inner wall of the outer box 3, causing the grinding plate 16 to continuously squeeze the Chinese herbal medicine pieces, thereby impacting and rubbing the Chinese herbal medicine pieces, so that the Chinese herbal medicine pieces are gradually crushed and refined.
[0044] The ground Chinese medicine powder falls into the discharge box 2 through the bottom of the outer box 3 under the action of gravity. After being guided by the first guide box 19, it falls precisely into the filter plate 23 inside the bottom box 1. The second motor 26 is started. The output end of the second motor 26 drives the rotating rod 27 to rotate, which in turn causes the second fixed plate 28 fixed at the bottom of the rotating rod 27 to start rotating inside the device box 24. As the second fixed plate 28 rotates, the four inclined blocks 29 at its bottom also make circular motion. Since the inclined blocks 29 are correspondingly set with the pulley 31, when the inclined blocks 29 rotate to contact the pulley 31, they will apply a downward pressure to the pulley 31, causing the filter plate 23 to move downward as a whole, thereby compressing the spring 33.
[0045] As the inclined block 29 continues to rotate away from the pulley 31, the spring 33, due to its own elastic restoring force, will push the filter plate 23 upward. This cycle repeats, causing the device box 24 to vibrate up and down. The frequency of the vibration is transmitted to the filter plate 23 through the first fixed plate 25, causing the filter plate 23 to vibrate as well. Under the action of vibration, the Chinese medicine powder accumulated on the filter plate 23 can become more loose, which is conducive to the powder passing through the filter plate 23 for screening. The Chinese medicine powder that meets the fineness requirements will pass through the filter plate 23 into the second guide box 22, and finally be discharged from the bottom box 1 through the discharge pipe 34 and collected as a qualified finished product.
[0046] Larger particles of Chinese herbal powder that fail to pass through filter plate 23 will remain on filter plate 23. With vibration, these larger particles will gradually move to the left and enter discharge pipe 36 through conveying pipe 35 and be discharged from bottom box 1. Operators can collect these substandard powders and put them back into the grinding device for secondary grinding, thereby ensuring the uniformity of particle size and quality stability of the final product.
[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
