Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and in particular to a multi-stage grinding device for processing Chinese herbal medicine slices. Background Art

[0002] Chinese herbal medicine slices refer to Chinese medicinal materials that have been processed and prepared under the guidance of traditional Chinese medicine theory and can be directly used for blending or preparation. This form of Chinese medicine usually includes various forms such as flakes, strips, and threads, which are convenient for clinical use. In the preparation process of Chinese medicine, some processes require grinding the Chinese herbal medicine slices before other operations. For example, when making Chinese herbal ointment prescriptions, some Chinese herbal medicine slices may be ground into fine powder first, and then mixed with the decocted medicinal liquid. There are also some Chinese herbal preparations for external use, such as Chinese herbal external application powder, which require the Chinese herbal medicine slices to be ground into extremely fine powder so that they can be better mixed with other matrices to adapt to different preparation and processing requirements.

[0003] Since the texture, hardness, water content and other factors of the Chinese herbal medicine slices themselves will affect the particle size and uniformity during the grinding process, when the grinder is running, there will be larger particles and smaller particles among the ground particles. Since the larger particles and smaller particles are unevenly distributed in the same particle group, they are subjected to different impact and shear forces during the grinding process, resulting in some particles being excessively worn while other particles are not fully ground, causing product unevenness and low yield.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 11 As shown, this embodiment proposes a multi-stage grinding device for processing Chinese herbal medicine slices, including a tank body 1, a feed hopper 2 is fixedly installed on the top of the tank body 1, and also includes a first partition 3, a second partition 4, a crushing component, a primary grinding component, a grinding disc 5, a secondary grinding component, an adjustment component and a receiving barrel 6. The first partition 3 is fixedly installed inside the tank body 1, and the second partition 4 is fixedly installed inside the tank body 1. The second partition 4 is located below the first partition 3. The crushing component is installed on the first partition 3 and is used to crush the Chinese herbal medicine slices into particles. The crushing component includes a crushing barrel 7, a first valve 8 , discharge pipe 9, second valve 10, crushing part and air inlet part, the crushing barrel 7 is fixedly installed between the first partition 3 and the inner top wall of the tank body 1; the top of the crushing barrel 7 is connected with the discharge end of the feed hopper 2, and the discharge end of the feed hopper 2 is installed with a first valve 8. There are two symmetrical and connected discharge pipes 9 on the crushing barrel 7, and the feed ends of the two discharge pipes 9 are close to the feed end of the crushing barrel 7. The feed ends of the two discharge pipes 9 are both installed with a second valve 10. The crushing part is installed inside the crushing barrel 7 for crushing Chinese herbal medicines, and the air inlet part is installed on the crushing part for exhausting air into the crushing barrel 7.

[0024] Specifically, when grinding the Chinese herbal medicine slices, the Chinese herbal medicine slices to be ground are first poured into the feed hopper 2, and then the first valve 8 is opened. At this time, the Chinese herbal medicine slices in the feed hopper 2 enter the crushing barrel 7, and then the first valve 8 is closed and the crushing part is started to crush the Chinese herbal medicine slices and crush them into particles for easy grinding. Then the second valve 10 is opened, and the air inlet part is started at this time. The air inlet part is connected to the corresponding equipment outside the crushing barrel 7 to blow air into the crushing barrel 7. Accompanied by the continuous stirring of the crushing part, the crushed Chinese herbal medicine slice particles are sent into the discharge pipe 9, which can be sent to the first level and the inside of the grinding component. The first level grinding component is started to further crush the Chinese herbal medicine slice particles, uniform the size of the Chinese herbal medicine slice particles, and avoid the mixing of larger particles in the Chinese herbal medicine slice particles. Then it is sent to the grinding disc 5 and further ground by the secondary grinding component. The position of the secondary grinding component can be adjusted by the setting of the adjustment component to facilitate the control of the grinding quality.

[0025] The above, such as Figure 4 、 Figure 5 As shown, the crushing part includes a drive shaft 11, a crushing knife 12, an impact rod 13, a connecting frame 14 and a first motor 15. The drive shaft 11 is rotatably installed inside the crushing barrel 7. Multiple groups of crushing knives 12 are detachably installed on the drive shaft 11 at equal distances. Each group of crushing knives 12 is arranged at equal angles in a circle. The multiple crushing knives 12 in each group of crushing knives 12 are staggered. Multiple groups of impact rods 13 are fixedly installed at equal distances on the drive shaft 11. Each group of impact rods 13 is arranged at equal angles in a circle. The multiple crushing knives 12 in each group of impact rods 13 are staggered. Among them, the multiple groups of crushing knives 12 and the multiple groups of impact rods 13 are staggered. A connecting frame 14 is fixedly installed on the bottom of the first partition 3. A first motor 15 is fixedly installed on the bottom of the connecting frame 14. The output end of the first motor 15 is fixedly connected to the drive shaft 11.

[0026] Specifically, when crushing the Chinese herbal medicine slices entering the crushing barrel, the first motor 15 is started, and the first motor 15 drives the drive shaft 11 to rotate, and the drive shaft 11 drives multiple crushing knives 12 and the impact rod 13 to rotate. The setting of the crushing knife 12 can cut and crush the Chinese herbal medicine slices, and the setting of the impact rod 13 can make the Chinese herbal medicine slices more disordered during the crushing process, thereby improving the crushing efficiency.

[0027] The above, such as Figure 4 、 Figure 5As shown, the air inlet part includes a connecting sleeve 16, a ventilation slot 17, a nozzle 18, an air inlet pipe 19 and a joint 20. The connecting sleeve 16 is rotatably mounted on the bottom of the drive shaft 11. The connecting sleeve 16 is fixedly connected to the bottom of the first partition 3, wherein the drive shaft 11 and multiple counterattack rods 13 are hollow structures, and multiple counterattack rods 13 are connected to the drive shaft 11. The bottom of the drive shaft 11 is circular and has multiple ventilation slots 17 at equal angles. The ventilation slots 17 are located inside the connecting sleeve 16. Each counterattack rod 13 is evenly connected to multiple nozzles 18. The air inlet pipe 19 is fixedly mounted on the tank body 1. The output end of the air inlet pipe 19 is connected to the connecting sleeve 16, and the input end of the air inlet pipe 19 is connected to the joint 20.

[0028] Specifically, after the crushing is completed, as the drive shaft 11 rotates, the drive shaft 11 drives the impact rod 13 to rotate. At this time, the equipment used for blowing air, such as a blower, etc., connects its output end with the connector 20, and then exhausts air into the air inlet pipe 19. The air entering the air inlet pipe 19 will enter the connecting sleeve 16. The air entering the connecting sleeve 16 will pass through the setting of the ventilation groove 17 and enter the inside of the drive shaft 11 and the ventilation groove 17. Then the nozzle 18 is turned on to blow the Chinese herbal medicine slices in the crushing barrel 7. Since the inner wall of the crushing barrel 7 is set to a conical structure with a wide upper part and a narrow lower part, as the drive shaft 11 continues to rotate, the air blows up the crushed Chinese herbal medicine slice particles. At this time, the second valve 10 is in an open state, and the blown Chinese herbal medicine slice particles can enter the discharge pipe 9.

[0029] like Figures 6 to 9 As shown, the first-level grinding assembly is installed on the second partition 4 and is used for preliminary grinding of Chinese herbal medicine slices. The first-level grinding assembly includes a grinding rack 21, a discharge rack 22, a filter screen 23, a rotating drum 24, a second motor 25 and an abrasive part. Two grinding racks 21 are tilted and fixedly installed on the upper part of the second partition 4. The two grinding racks 21 are symmetrically arranged. The two grinding racks 21 are respectively connected to the discharge ends of the two discharge pipes 9. The bottoms of the two grinding racks 21 are symmetrically and fixedly installed with two discharge racks 22. The bottom of the discharge rack 22 is connected to the second partition 4, and the two grinding racks 21 are fixedly installed with a filter screen plate 23 at the docking position with the discharge rack 22. A rotating cylinder 24 is rotatably installed inside the two grinding racks 21. The position where the grinding rack 21 is connected to the discharge pipe 9 is located inside the rotating cylinder 24. A second motor 25 is fixedly installed on the two grinding racks 21, and the output end of the second motor 25 is fixedly connected to the rotating cylinder 24. Abrasive parts are installed on the two rotating cylinders 24 for grinding Chinese herbal medicine slices.

[0030] Specifically, after the crushed Chinese herbal medicine particles enter the rotating cylinder 24 through the discharge pipe 9, the Chinese herbal medicine particles will fall into the inside of the grinding machine frame 21. At this time, the second motor 25 is started, and the second motor 25 drives the rotating cylinder 24 to rotate, which can drive the abrasive part to rotate, thereby grinding the Chinese herbal medicine particles entering the grinding machine frame 21. As the rotating cylinder 24 continues to rotate, with the cooperation of the abrasive part, the ground Chinese herbal medicine particles will pass through the filter plate 23. At this time, the ground Chinese herbal medicine particles will pass through the filter plate 23, uniforming the particle size of the Chinese herbal medicine particles, which is convenient for subsequent grinding and not easily stuck. The Chinese herbal medicine particles enter the discharge rack 22, and the Chinese herbal medicine particles entering the discharge rack 22 will enter the grinding disk 5 and can be ground again.

[0031] The above, such as Figure 9 As shown, the abrasive part includes a feed trough 26, a positioning frame 27, a lower pressure frame 28, a grinding roller 29 and a spring 30. A plurality of feed troughs 26 are provided on the two rotating cylinders 24 at equal angles in a circular shape. A plurality of positioning frames 27 are fixedly installed on the two rotating cylinders 24 at equal angles in a circular shape. The plurality of positioning frames 27 are staggered with the plurality of feed troughs 26. A lower pressure frame 28 is slidably installed in each positioning frame 27. A grinding roller 29 is rotatably installed at the bottom of each lower pressure frame 28. The grinding roller 29 abuts against the inner wall of the abrasive frame 21. A plurality of springs 30 are fixedly installed at equal distances inside each positioning frame 27. The spring 30 is fixedly connected to the positioning frame 27. It also includes a brush 31. A plurality of brushes 31 are detachably installed on the two rotating cylinders 24 in a circular shape. The bristle part of the brush 31 abuts against the inner wall of the abrasive frame 21.

[0032] Specifically, the Chinese herbal medicine pieces particles after entering the rotating drum 24 will pass through the feeding chute 26 and fall into the inside of the grinding machine frame 21. As the rotating drum 24 continues to rotate, the rotating drum 24 drives the positioning frame 27 to move, the positioning frame 27 drives the lower pressing frame 28 to move, and the lower pressing frame 28 drives the grinding roller 29 to move. Under the action of the spring 30, the grinding roller 29 always abuts against the inner side wall of the grinding machine frame 21. When grinding the Chinese herbal medicine pieces, even if some larger particles are encountered, the grinding quality is also maintained stable. Under the action of the brush 31, the Chinese herbal medicine particles ground by the grinding roller 29 can be brushed to the position of the filter screen 23, where a part of the Chinese herbal medicine particles will pass through the filter screen 23 and enter the discharge rack 22, while the Chinese herbal medicine particles with larger particle size that have not passed through the filter screen 23 will be brushed to the highest point inside the grinding machine frame 21 by the brush 31. At this time, the Chinese herbal medicine particles fall to the position of the discharge chute 26 and eventually reach the bottom of the inside of the grinding machine frame 21 and are ground again until all the Chinese herbal medicine particles enter the inside of the discharge rack 22.

[0033] like Figure 10As shown, the grinding disc 5 is fixedly mounted on the inner bottom wall of the tank body 1, and the secondary grinding assembly is mounted on the second partition 4 for grinding Chinese herbal medicine slices. The secondary grinding assembly includes a positioning ring 32, a grinding head 33, a fixing frame 34, a sliding cylinder 35 and a driving part. The positioning ring 32 is fixedly mounted on the bottom of the second partition 4, and the grinding head 33 is rotatably mounted in the positioning ring 32. The fixing frame 34 is fixedly mounted on the top of the grinding head 33. The sliding cylinder 35 is rotatably mounted on the second partition 4. The sliding cylinder 35 is slidably connected to the fixing frame 34. The driving part is mounted on the sliding cylinder 35 for driving the grinding head 33 to rotate.

[0034] Specifically, the Chinese herbal medicine particles entering the discharge rack 22 will enter the grinding disc 5. At this time, the driving part is started, and the driving part drives the sliding cylinder 35 to rotate, and the sliding cylinder 35 drives the fixed frame 34 to rotate, and the fixed frame 34 drives the grinding head 33 to rotate, thereby grinding the Chinese herbal medicine particles entering the grinding disc 5. Since the taper of the grinding head 33 is smaller than the taper of the grinding disc 5, the Chinese herbal medicine particles entering the grinding disc 5 can more easily enter the gap between the grinding disc 5 and the grinding head 33. As the gap between the grinding disc 5 and the grinding head 33 becomes smaller and smaller, the Chinese herbal medicine particles are ground into the required size, and the grinding is completed.

[0035] The above, such as Figure 10 As shown, the driving part includes a driven helical gear 36, a third motor 37 and a driving helical gear 38. The driven helical gear 36 is fixedly mounted on the top of the sliding cylinder 35, the third motor 37 is fixedly mounted on the second partition 4, and the output end of the third motor 37 is fixedly mounted with the driving helical gear 38, which is engaged with the driven helical gear 36.

[0036] Specifically, when the grinding head 33 is driven to rotate, the third motor 37 is started, the third motor 37 drives the active bevel gear 38 to rotate, the active bevel gear 38 drives the driven bevel gear 36 to rotate, and the sliding cylinder 35 can be driven to rotate. With the cooperation of the grinding disc 5, the Chinese herbal medicine particles are ground by the grinding head 33.

[0037] like Figure 11 As shown, a positioning assembly is installed on the secondary grinding assembly for adjusting the grinding position. The receiving barrel 6 is detachably installed at the bottom of the tank body 1, and the receiving barrel 6 is arranged at the discharge end of the grinding disc 5. The positioning assembly includes a positioning screw 39 and an adjusting nut 40. The positioning screw 39 is rotatably installed on the top of the sliding barrel 35, and the positioning nut 40 is threadedly sleeved on the top of the fixing frame 34. The positioning nut 40 is fixedly connected to the fixing frame 34.

[0038] Specifically, after the Chinese herbal medicine particles enter the grinding disk 5, when the Chinese herbal medicine particles are ground, in order to adjust the particle size of the grind, the adjusting screw 39 is screwed at this time, and the adjusting screw 39 pushes the adjusting nut 40 to move, thereby pushing the fixed frame 34 and the sliding cylinder 35 to move relative to each other through the setting of the adjusting nut 40, thereby pushing the grinding head 33 to move in the positioning ring 32, and then adjusting the relative position between the grinding head 33 and the grinding disk 5, so as to facilitate the control of the grinding quality.

[0039] To sum up, when grinding Chinese herbal medicine slices, first pour the Chinese herbal medicine slices to be ground into the feed hopper 2, and then open the first valve 8. At this time, the Chinese herbal medicine slices in the feed hopper 2 enter the crushing barrel 7, and then close the first valve 8, start the first motor 15, and the first motor 15 drives the drive shaft 11 to rotate. The drive shaft 11 drives multiple crushing knives 12 and the impact rod 13 to rotate. The setting of the crushing knife 12 can cut and crush the Chinese herbal medicine slices, and the setting of the impact rod 13 can make the Chinese herbal medicine slices more disordered during the crushing process, thereby improving the crushing efficiency and crushing the Chinese herbal medicine slices into particles.

[0040] After the crushing is completed, the second valve 10 is opened. At this time, the equipment used for blowing, such as a blower, etc., is connected to the output end of the connector 20, and then the air is discharged into the air inlet pipe 19. The air entering the air inlet pipe 19 will enter the connecting sleeve 16. The air entering the connecting sleeve 16 will pass through the setting of the ventilation groove 17 and enter the inside of the drive shaft 11 and the ventilation groove 17. Then the nozzle 18 is opened to blow the Chinese herbal medicine slices in the crushing barrel 7. Since the inner wall of the crushing barrel 7 is set to a conical structure with a wide upper part and a narrow lower part, as the drive shaft 11 continues to rotate, the air blows up the crushed Chinese herbal medicine slice particles. At this time, the second valve 10 is in an open state, and the blown Chinese herbal medicine slice particles can enter the discharge pipe 9.

[0041] After the crushed Chinese herbal medicine pieces particles pass through the discharge pipe 9 and enter the rotating drum 24, the Chinese herbal medicine pieces particles will pass through the discharge chute 26 and fall into the inside of the grinding machine frame 21. As the rotating drum 24 continues to rotate, the rotating drum 24 drives the positioning frame 27 to move, the positioning frame 27 drives the lower pressing frame 28 to move, and the lower pressing frame 28 drives the grinding roller 29 to move. Under the action of the spring 30, the grinding roller 29 always abuts against the inner side wall of the grinding machine frame 21. When grinding the Chinese herbal medicine pieces particles, even if some larger particles are encountered, the grinding quality is also maintained stable. Under the action of the brush 31 The Chinese herbal medicine particles ground by the grinding roller 29 can be brushed to the position of the filter screen 23, wherein a part of the Chinese herbal medicine particles will pass through the filter screen 23 and enter the discharge rack 22, while the Chinese herbal medicine particles with larger particle size that have not passed through the filter screen 23 will be brushed to the highest point inside the grinding machine frame 21 by the brush 31. At this time, the Chinese herbal medicine particles fall to the position of the discharge chute 26 and eventually reach the bottom of the inside of the grinding machine frame 21 and are ground again until all the Chinese herbal medicine particles enter the inside of the discharge rack 22. The Chinese herbal medicine particles that enter the discharge rack 22 will enter the grinding disc 5.

[0042] In order to adjust the particle size of the ground material, the adjusting screw 39 is screwed, and the adjusting screw 39 pushes the adjusting nut 40 to move, thereby pushing the fixed frame 34 and the sliding cylinder 35 to move relative to each other through the setting of the adjusting nut 40, thereby pushing the grinding head 33 to move in the positioning ring 32, and then adjusting the relative position between the grinding head 33 and the grinding disc 5, and then starting the third motor 37, the third motor 37 drives the active bevel gear 38 to rotate, and the active bevel gear 38 drives the driven bevel gear 36 to rotate, which can drive the sliding cylinder 35 to rotate. The sliding cylinder 35 drives the fixed frame 34 to rotate, and the fixed frame 34 drives the grinding head 33 to rotate, thereby grinding the Chinese herbal medicine particles entering the grinding disk 5. Since the taper of the grinding head 33 is smaller than the taper of the grinding disk 5, the Chinese herbal medicine particles entering the grinding disk 5 are more convenient to enter the pores between the grinding disk 5 and the grinding head 33. As the gap between the grinding disk 5 and the grinding head 33 becomes smaller and smaller, the Chinese herbal medicine particles are ground into the required size, and the grinding is completed. The ground Chinese herbal medicine particles will fall into the inside of the collecting cylinder 6 and be collected.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
