[0002] In the process of the modernization development of traditional Chinese medicine, the ultrafine powder technology of traditional Chinese medicine decoction pieces has been increasingly emphasized. Ultrafine pulverization can significantly improve the dissolution rate and dissolution ratio of the active ingredients of traditional Chinese medicine decoction pieces, enhance their pharmacological activities, and thus improve the efficacy and clinical curative effect of traditional Chinese medicine. However, traditional crushing equipment for traditional Chinese medicine decoction pieces has many limitations when facing the demand for ultrafine powder preparation.

Due to the wide variety of traditional Chinese medicine decoction pieces, there are great differences in their physical properties such as texture, hardness, and fiber content. For some traditional Chinese medicine decoction pieces with hard texture and high fiber content, a single crushing method is likely to result in incomplete crushing, with a large amount of large particle materials that do not meet the ultrafine powder standard remaining, affecting the product quality; while for the relatively soft decoction pieces, it may cause energy waste due to excessive crushing and the loss or property change of active ingredients due to overheating of the materials caused by friction.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention is provided with a crushing component. The crushing hammer rotates driven by the output shaft of the driving motor to initially crush the input traditional Chinese medicine decoction pieces. The crushed materials fall on the filter plate, and the smaller particles pass through the filter plate and fall down, while the larger particles continue to be crushed between the crushing hammer and the annular crushing teeth. The timely falling of the smaller particles into the next step of processing avoids problems such as energy waste and overheating of the materials caused by excessive crushing; the larger particles remain above and continue to be crushed, ensuring the effectiveness and accuracy of crushing, and also preventing the grinding component from being interrupted or stuck due to uneven particle sizes of the materials, maintaining the continuity and stability of production.

[0015] 2. The present invention is provided with a grinding component. When the driving motor operates, it drives the grinding component to operate through its output shaft. The turntable in the grinding component rotates inside the annular sieve plate. Under the guidance of the spline shaft, the grinding block rotates with the turntable and performs fine grinding at the bottom of the grinding ring. This way of hierarchical processing makes the entire ultrafine powder crushing process more orderly and efficient, and can meet the processing requirements of different types and textures of traditional Chinese medicine decoction pieces.

[0016] 3. The present invention is provided with a grinding component. The powder after being ground by the grinding block falls onto the surface of the turntable. As the turntable rotates, the powder is thrown onto the surface of the annular sieve plate after being guided by the arc-shaped groove, so that the powder can be evenly dispersed on the annular sieve plate to avoid local accumulation of materials on the sieve plate. At the same time, the scraper rotates with the turntable and scrapes the materials on the top of the annular sieve plate, which can prevent the accumulation of materials from blocking the sieve holes. After grinding, the ultrafine powder meeting the particle size requirements passes through the annular sieve plate and falls down, ensuring the continuity of the material processing process.

[0017] 4. The present invention is provided with a grinding component. When the rotating ring rotates, the threaded ring can slide up and down with the rotation of the rotating ring. At this time, the connecting plate slides up and down along the surface of the limiting rod and drives the annular sieve plate to move in the processing box. At this time, the grinding block in the grinding component moves together, so that the distance between the grinding block and the grinding ring can be adjusted, and thus the purpose of accurately controlling the final particle size of the ultrafine powder of traditional Chinese medicine decoction pieces can be achieved.

[0018] 5. The present invention is provided with a feeding component. The powder after grinding first falls onto the blanking plate. When the arc-shaped feeding plate rotates, it can push the powder to the edge of the blanking plate. At this time, the boosting wheel in contact with the outer wall of the arc-shaped feeding plate is pushed, and the movement of the boosting wheel drives the feeding plate to rotate around its connection point with the blanking plate, thereby forcing the torsion spring to be stressed and twisted. The rotation of the feeding plate can push the powder intercepted by it towards the direction of the discharge pipe, reducing the residue amount of materials inside the equipment.

[0019] 6. The present invention is provided with a blowing assembly. The suction fan rotates synchronously and inhales external air into the processing box. Subsequently, the air is sent to the blowing assembly through the ventilation pipe and the connecting hose. When the air enters the sealing shell through the air guide pipe, under the action of atmospheric pressure, the sliding plate slides towards the side away from the mounting plate. At this time, the interior of the sealing shell is communicated with the air guide hole through the through hole, and the airflow flowing out of the ventilation block blows downward along the processing box. This downward airflow can play a fluidizing role on the traditional Chinese medicine decoction pieces being crushed and ground in the processing box, and also reduce the residue and overflow of dust in the processing box.

[0020] 7. The present invention is provided with a tension spring. When the air enters the sealing shell through the air guide pipe, under the action of atmospheric pressure, the sliding plate slides towards the side away from the mounting plate. At this time, the ventilation block slides downward along the guide rod, and the tension spring is stretched by force. When the device is not in use, the tension spring drives the ventilation block to reset, so that the guide rod blocks the air guide hole, and it can also prevent dust from entering the blowing assembly.

The bottom of the connecting plate 83 is fixedly connected with an annular sieve plate 84. The center of the annular sieve plate 84 is rotatably connected with a powder grinding component 85. The inner wall of the connecting plate 83 is slidably connected with a limiting rod 86. The outer side of the limiting rod 86 is fixedly connected with a compression spring 87. The inner side of the rotating ring 81 is rotatably connected to the outer wall of the processing box 1. The outer wall of the processing box 1 is slidably connected with the inner side of the threaded ring 82. The outer wall of the connecting plate 83 is slidably connected to the inner wall of the processing box 1. The outer side of the annular sieve plate 84 is slidably connected to the inner wall of the processing box 1.

The top of the compression spring 87 is fixedly connected to the outer side of the connecting plate 83. The connecting plates 83 are arranged annularly along the central axis of the threaded ring 82. When the rotating ring 81 is rotated, the threaded ring 82 can slide up and down as the rotating ring 81 rotates. At this time, the connecting plate 83 slides up and down along the surface of the limiting rod 86 and drives the annular sieve plate 84 to move in the processing box 1. At this time, the grinding block 852 in the powder grinding component 85 moves together, so that the distance between the grinding block 852 and the grinding ring 94 can be adjusted, and thus the purpose of accurately controlling the final particle size of the ultrafine powder of traditional Chinese medicine pieces can be achieved. Among them, the rotation of the threaded ring 82 is restricted by the connecting plate 83, the limiting rod 86 and the compression spring 87.

[0024] The powder grinding component 85 includes a turntable 851. A grinding block 852 is fixedly connected to the top of the turntable 851. A spline shaft 854 is slidably connected to the center of the grinding block 852. A scraper 855 is fixedly connected to the outside of the turntable 851. The outside of the turntable 851 is rotatably connected to the inside of an annular sieve plate 84. The grinding block 852 is located at the bottom of a grinding ring 94. The inside of the spline shaft 854 is fixedly connected to the output shaft of a driving motor 5. The bottom of the scraper 855 is slidably connected to the top of the annular sieve plate 84. An arc-shaped groove 853 is formed in the wall of the turntable 851. The turntable 851 in the powder grinding component 85 rotates inside the annular sieve plate 84. Under the guidance of the spline shaft 854, the grinding block 852 rotates along with the turntable 851 and performs fine grinding at the bottom of the grinding ring 94. This grading treatment method makes the entire ultrafine powder crushing process more orderly and efficient, and can meet the processing requirements of different types and textures of traditional Chinese medicine decoction pieces. The powder after being ground by the grinding block 852 falls onto the surface of the turntable 851. As the turntable 851 rotates, the powder is thrown onto the surface of the annular sieve plate 84 after being guided by the arc-shaped groove 853, so that the powder can be evenly dispersed on the annular sieve plate 84 to avoid local accumulation of materials on the sieve plate. At the same time, as the turntable 851 rotates, the scraper 855 scrapes the materials on the top of the annular sieve plate 84, which can prevent the materials from accumulating and blocking the sieve holes. After grinding, the ultrafine powder meeting the particle size requirements falls through the annular sieve plate 84, ensuring the continuity of the material processing process; During the crushing process, the driving motor 5 drives the material pushing component 7 to rotate. The material pushing component 7 pushes the crushed materials towards the edge of the processing box 1, so that they are discharged from the discharge pipe 4 outside the processing box 1.

[0025] The material pushing component 7 includes a blanking plate 71. An arc-shaped material pushing plate 72 is rotatably connected to the inside of the blanking plate 71. A feeding plate 73 is rotatably connected to the inside of the blanking plate 71. A torsion spring 74 is fixedly connected to the inside of the feeding plate 73.

The bottom end of the torsion spring 74 is fixedly connected to the outer wall of the blanking plate 71. The outer wall of the boosting wheel 75 is in contact with the outer wall of the arc-shaped material pushing plate 72. The center of the arc-shaped material pushing plate 72 is fixedly connected to the output shaft of the driving motor 5. The outer wall of the blanking plate 71 is fixedly connected to the inner wall of the processing box 1. During the crushing process, the driving motor 5 drives the material pushing component 7 to rotate. The material pushing component 7 pushes the crushed materials towards the edge of the processing box 1, so that they are discharged from the discharge pipe 4 outside the processing box 1; the ground powder first falls onto the blanking plate 71. When the arc-shaped material pushing plate 72 rotates, it can push the powder to the edge of the blanking plate 71. At this time, the boosting wheel 75 in contact with the outer wall of the arc-shaped material pushing plate 72 is pushed. The movement of the boosting wheel 75 drives the feeding plate 73 to rotate around its connection point with the blanking plate 71, thereby forcing the torsion spring 74 to be torsionally stressed. The rotation of the feeding plate 73 can push the powder intercepted by it towards the direction of the discharge pipe 4, reducing the residual amount of materials inside the equipment.

[0026] The air blowing assembly 12 includes a sealing shell 121. A gas guide pipe 122 is fixedly connected to the top of the sealing shell 121. A mounting plate 123 is fixedly connected to the top of the inner wall of the sealing shell 121. A guide rod 124 is fixedly connected to the inner wall of the mounting plate 123. An air vent block 126 is slidably connected to the outer wall of the guide rod 124. A tension spring 125 is fixedly connected to the top of the air vent block 126. A sliding plate 127 is fixedly connected to the outside of the air vent block 126. The outer wall of the sealing shell 121 is fixedly connected to the inner side of the cover plate 3. The top end of the gas guide pipe 122 is fixedly connected to the top end of the connecting hose 11. A through hole 128 is formed in the wall of the air vent block 126. An air guide hole 129 is formed in the inner side of the air vent block 126. The top end of the tension spring 125 is fixedly connected to the bottom of the mounting plate 123. The outer wall of the sliding plate 127 is slidably connected to the inner wall of the sealing shell 121. While the driving motor 5 is rotating, the suction fan 6 rotates synchronously and sucks outside air into the processing box 1. Then, the air is sent to the air blowing assembly 12 through the air pipe 10 and the connecting hose 11. When the air enters the sealing shell 121 through the gas guide pipe 122, under the action of atmospheric pressure, the sliding plate 127 slides to the side away from the mounting plate 123. At this time, the air vent block 126 slides downward along the guide rod 124, so that the bottom of the air vent block 126 is separated from the guide rod 124. At this time, the tension spring 125 is stretched. The inside of the sealing shell 121 is communicated with the air guide hole 129 through the through hole 128, so that the air entering the sealing shell 121 can enter through the through hole 128 of the air vent block 126 and then flow out through the air guide hole 129. Finally, the air flow flowing out of the air vent block 126 blows downward along the processing box 1. This downward air flow can play a fluidizing role on the traditional Chinese medicine decoction pieces materials being broken and ground in the processing box 1, making the materials more evenly distributed, improving the efficiency of breaking and grinding, reducing the residue and overflow of dust in the processing box 1, keeping the working environment clean and ensuring the quality of products. When the device is not in use, the tension spring 125 drives the air vent block 126 to reset, so that the guide rod 124 blocks the air guide hole 129 and can also prevent dust from entering the air blowing assembly 12.

[0027] Working principle: During use, after the driving motor 5 is started, its output shaft drives the suction fan 6, the feeding assembly 7 and the crushing hammer 92 in the crushing assembly 9 to rotate simultaneously. First, the traditional Chinese medicine decoction pieces to be crushed are put into the processing box 1 from the cover plate 3 at the top of the processing box 1. Among them, the support legs 2 can stably support the processing box 1. The crushing component 9 starts to work. The annular crushing teeth 91 are fixed to the inner wall of the processing box 1, and the crushing hammer 92 rotates driven by the output shaft of the driving motor 5 to initially crush the input traditional Chinese medicine pieces. The crushed materials fall on the filter plate 93. The smaller particles pass through the filter plate 93 and fall down, while the larger particles continue to be crushed between the crushing hammer 92 and the annular crushing teeth 91. At the same time, the grinding ring 94 at the bottom of the filter plate 93 also participates in the initial grinding process of the materials, realizing the initial classification of the materials. The smaller particles fall down in time for the next step of processing, avoiding problems such as energy waste and overheating of the materials caused by excessive crushing. The larger particles remain above and continue to be crushed, ensuring the effectiveness and accuracy of crushing. It can also prevent the grinding component 8 from being interrupted or stuck due to uneven particle sizes of the materials, maintaining the continuity and stability of production.

[0028] Meanwhile, the grinding component 8 works synchronously. When the driving motor 5 operates, the grinding part 85 is driven to rotate through its output shaft. The turntable 851 in the grinding part 85 rotates inside the annular sieve plate 84. Under the guidance of the spline shaft 854, the grinding block 852 rotates with the turntable 851 and finely grinds at the bottom of the grinding ring 94. This way of classification processing makes the entire ultrafine powder crushing process more orderly and efficient, and can meet the processing requirements of different types and textures of traditional Chinese medicine pieces.

[0029] During this process, the powder ground by the grinding block 852 falls onto the surface of the turntable 851. As the turntable 851 rotates, the powder is thrown onto the surface of the annular sieve plate 84 after being guided by the arc-shaped groove 853, enabling the powder to spread evenly on the annular sieve plate 84 to avoid local accumulation of materials on the sieve plate. At the same time, the scraper 855 rotates with the turntable 851 to scrape the materials on the top of the annular sieve plate 84, preventing the materials from accumulating and blocking the sieve holes. After grinding, the ultrafine powder meeting the particle size requirements passes through the annular sieve plate 84 and falls down, ensuring the continuity of the material processing process.

[0030] When the rotating ring 81 is rotated, the threaded ring 82 can slide up and down with the rotation of the rotating ring 81. At this time, the connecting plate 83 slides up and down along the surface of the limiting rod 86, driving the annular sieve plate 84 to move inside the processing box 1. At this time, the grinding block 852 in the grinding part 85 moves together, thereby adjusting the distance between the grinding block 852 and the grinding ring 94, and further achieving the purpose of accurately controlling the final particle size of the ultrafine powder of traditional Chinese medicine pieces. Among them, the rotation of the threaded ring 82 is restricted by the connecting plate 83, the limiting rod 86 and the compression spring 87.

[0031] During the crushing process, the driving motor 5 drives the pushing component 7 to rotate. The pushing component 7 pushes the crushed materials to the edge of the processing box 1, and discharges them from the discharge pipe 4 outside the processing box 1.

[0032] The ground powder first falls onto the blanking plate 71. When the arc-shaped pushing plate 72 rotates, the powder can be pushed to the edge of the blanking plate 71. At this time, the boosting wheel 75 in contact with the outer wall of the arc-shaped pushing plate 72 is pushed. The movement of the boosting wheel 75 drives the feeding plate 73 to rotate around its connection point with the blanking plate 71, thereby forcing the torsion spring 74 to be torsionally stressed. The rotation of the feeding plate 73 can push the powder intercepted by it towards the direction of the discharge pipe 4, reducing the residual amount of materials inside the equipment.

[0033] While the driving motor 5 rotates, the suction fan 6 rotates synchronously and inhales the outside air into the processing box 1. Subsequently, the air is sent into the blowing assembly 12 through the ventilation pipe 10 and the connecting hose 11. When the air enters the sealing shell 121 through the air guide pipe 122, under the action of atmospheric pressure, the sliding plate 127 slides towards the side away from the mounting plate 123. At this time, the ventilation block 126 slides downward along the guide rod 124. The bottom of the ventilation block 126 is separated from the guide rod 124. At this time, the tension spring 125 is stretched. The inside of the sealing shell 121 is connected to the air guide hole 129 through the through hole 128, so that the air entering the sealing shell 121 can enter through the through hole 128 of the ventilation block 126 and then flow out through the air guide hole 129. Finally, the air flow flowing out of the ventilation block 126 blows downward along the processing box 1; This downward air flow can play a fluidizing role on the traditional Chinese medicine decoction pieces materials being crushed and ground inside the processing box 1, making the materials more evenly distributed, improving the efficiency of crushing and grinding; reducing the residue and overflow of dust inside the processing box 1, keeping the working environment clean and ensuring the quality of the product. When the device is not in use, the tension spring 125 drives the ventilation block 126 to reset, so that the guide rod 124 blocks the air guide hole 129, and can also prevent dust from entering the blowing assembly 12.
