Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and more specifically, to a grinding device for fine grinding. Background Technology

[0002] Dendrobium, a traditional Chinese medicine, has stems rich in active ingredients such as polysaccharides, alkaloids, amino acids, and trace elements. It has pharmacological effects such as nourishing yin and stomach, enhancing immunity, and anti-oxidation. However, the dense fibrous structure of Dendrobium results in a low dissolution rate of active ingredients when directly decocted or soaked, affecting the efficacy of the medicine. Therefore, physical processing of Dendrobium through grinding technology can significantly improve its utilization rate and facilitate the development and application of subsequent preparations.

[0003] A search revealed that Chinese patent CN218107921U discloses "a high-efficiency and fine grinding device for Chinese medicinal materials, which uses a semi-circular gear and an intermittent gear, and a swing motor to drive the intermittent gear to rotate, causing the grinding bucket to swing back and forth. The swinging grinding bucket can increase the grinding range of the grinding head, thereby reducing grinding dead angles and avoiding uneven grinding. By setting a sleeve and a push rod, when the swing motor drives the grinding bucket to swing, the push rod and the stop block can fix the grinding bucket, thereby reducing the work of the swing motor and indirectly reducing energy consumption." However, the following defects still exist:

[0004] When this device is used to grind traditional Chinese medicines such as Dendrobium, the grinding friction between the grinding head and the medicinal materials generates high temperatures. These temperatures accumulate during continuous grinding, and because timely heat dissipation is impossible, the temperature in the grinding area continues to rise, causing problems with the medicinal properties of the herbs and significantly reducing grinding efficiency. Therefore, a fine grinding device is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that during the grinding process of traditional Chinese medicines such as Dendrobium, the grinding friction between the grinding head and the medicinal material generates high temperatures. These temperatures accumulate during continuous grinding, and because heat cannot be dissipated in time, the temperature in the grinding area continues to rise, which in turn affects the medicinal properties of the medicinal material and significantly reduces the grinding efficiency.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: a fine grinding device, comprising a tank, wherein the interior of the tank is provided with a grinding component for multiple grinding of medicinal materials, and the bottom of the tank is provided with a sieving component for filtering and sieving the medicinal materials.

[0008] The grinding assembly includes a fixed tank fixedly connected to the inside of the main body. A servo motor is bolted to the top of the fixed tank. A fixed rod is coaxially mounted on the output end of the servo motor. Multiple fixed rings are fixedly connected to the outer wall of the fixed rod. Multiple grinding rollers are fixedly connected to the outer wall of the fixed rod. Three grinding rings are fixedly connected to the inner wall of the fixed tank. A funnel is fixedly connected to the bottom of the fixed tank. A spiral guide pipe is provided on the outer wall of the fixed tank. A fan is provided at one end of the spiral guide pipe. An air outlet pipe is fixedly connected to the end of the spiral guide pipe away from the fan. A storage frame is fixedly connected to the bottom of the main body. A water injection pipe is fixedly connected to the top of the main body. A water outlet pipe is fixedly connected to the outer wall of the main body. A feed frame is fixedly connected to one side of the fixed tank.

[0009] As a preferred technical solution of this utility model, the screening component includes two guide rails fixedly connected to the inner wall of the storage frame, multiple springs fixedly connected to the inner top wall of the two guide rails, and a fixing plate fixedly connected to the end of each of the multiple springs away from the guide rails. A screen is slidably connected to the inner wall of the two guide rails, and the screen is located at the bottom of the fixing plate. A drawer is slidably connected to the inner bottom wall of the storage frame, and a baffle is hinged to one side of the storage frame.

[0010] As a preferred technical solution of this utility model, a protrusion is fixedly connected to the top of the fixing ring, a positioning ring is rotatably connected to the outer wall of the fixing rod, a positioning plate is fixedly connected to the outer wall of the positioning ring, the side of the positioning plate away from the positioning ring is fixedly connected to the inner wall of the fixing tank, and a scraper is provided at the bottom of the positioning plate.

[0011] As a preferred technical solution of this utility model, extension blocks are fixedly connected to both sides of the storage frame, and extension columns are fixedly connected to one side of each of the two extension blocks. Two clamps are hinged to one side of the baffle.

[0012] As a preferred technical solution of this utility model, the inner wall of the feed frame is fixedly connected with a plurality of guide plates, and the plurality of guide plates are evenly distributed along the length direction of the feed frame.

[0013] As a preferred technical solution of this utility model, the inner walls of the three grinding rings are provided with multiple grooves, and the multiple grooves are evenly distributed along the height direction of the grinding ring.

[0014] As a preferred technical solution of this utility model, the outer wall of the fixed tank is provided with an observation frame, and the interior of the observation frame is provided with tempered glass.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Through the set grinding components, multiple and efficient grinding effects of Dendrobium are achieved.

The spiral guide pipe and the fan form an effective airflow circulation, and the fixed tank is cooled by water source, which effectively avoids the degradation of the effective components in Dendrobium caused by the accumulation of high temperature, and greatly improves the grinding efficiency.

[0017] 2. The sieving components enable the grading and screening of ground medicinal powder. During vibration, the springs between the guide rail and the fixed plate continuously compress and rebound, causing the screen to vibrate at a low amplitude and high frequency in the vertical direction, which significantly improves the sieving efficiency. The drawer can be pulled out to facilitate the collection of qualified medicinal materials, while the baffle ensures the sealing and safety of the sieving process. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes a fine grinding device, including a tank 1, a grinding component 2 for multiple grinding of medicinal materials is provided inside the tank 1, and a sieving component 3 for filtering and sieving the medicinal materials is provided at the bottom of the tank 1.

[0029] like Figures 2-4As shown, the grinding assembly 2 includes a fixed tank 201 fixedly connected to the inside of the tank body 1. A servo motor 202 is bolted to the top of the fixed tank 201. A fixed rod 203 is coaxially arranged at the output end of the servo motor 202. Multiple fixed rings 204 are fixedly connected to the outer wall of the fixed rod 203. Multiple grinding rollers 205 are fixedly connected to the outer wall of the fixed rod 203. Three grinding rings 206 are fixedly connected to the inner wall of the fixed tank 201. The servo motor 202 drives the multiple grinding rollers 205 to rotate, performing multiple grinding operations on the Dendrobium. A funnel 207 is fixedly connected to the bottom of the fixed tank 201. A screw thread is provided on the outer wall of the fixed tank 201. A spiral guide pipe 208 is provided with a fan 209 at one end and an air outlet pipe 210 fixedly connected to the end of the spiral guide pipe 208 away from the fan 209. A storage frame 211 is fixedly connected to the bottom of the tank 1 and a water injection pipe 212 is fixedly connected to the top of the tank 1. A water outlet pipe 213 is fixedly connected to the outer wall of the tank 1. Cold air is blown out by the fan 209 and water is injected through the spiral guide pipe 208 and the water injection pipe 212 to cool the fixed tank 201 in two ways. A feeding frame 214 is fixedly connected to one side of the fixed tank 201. Dendrobium is poured into the fixed tank 201 through the feeding frame 214. Dendrobium is poured into the fixed tank 201 through the feeding frame 214. The servo motor 202 starts, driving the fixed rod 203 to rotate. The multiple grinding rollers 205 on the fixed rod 203 rotate accordingly. The Dendrobium is squeezed and ground between the grinding rollers 205 and the grinding ring 206. The gap between the grinding rollers 205 and the grinding ring 206 forms a multi-stage crushing zone, thereby achieving multiple grinding of the Dendrobium. The ground Dendrobium falls into the storage frame 211 through the funnel 207. The fan 209 blows out cold air, which is guided by a spiral guide. The flow pipe 208 cools the fixed tank 201. The heat-absorbing airflow is discharged through the air outlet pipe 210. At the same time, water is injected into the tank 1 through the water injection pipe 212. The water source, together with the cold air in the spiral guide pipe 208, cools the fixed tank 201. This dual and efficient cooling effectively suppresses the heat generated during the grinding process, prevents the internal temperature of the fixed tank 201 from becoming too high, ensures that the heat-sensitive components of Dendrobium and other medicinal materials are not damaged, and guarantees the quality of the final product.

[0030] like Figure 3 and Figure 4As shown, the sieving assembly 3 includes two guide rails 301 fixedly connected to the inner wall of the storage frame 211. Multiple springs 302 are fixedly connected to the inner top wall of the two guide rails 301. Each end of the multiple springs 302 away from the guide rails 301 is fixedly connected to a fixing plate 303. A screen 304 is slidably connected to the inner wall of the two guide rails 301. The screen 304 is located at the bottom of the fixing plate 303. Through the springs 302 in the guide rails 301, the screen 304 forms a secondary vibration in the guide rails 301, performing double vibration sieving on the ground Dendrobium. A drawer 305 is slidably connected to the inner bottom wall of the storage frame 211. By pulling out the drawer 305, qualified Dendrobium can be collected. A baffle 306 is hinged to one side of the storage frame 211. By opening the baffle 306, the screen 304 can be pulled out to discharge coarse Dendrobium particles. When grinding Dendrobium, the ground Dendrobium powder falls onto the surface of the screen 304. The screen 304 vibrates due to the impact of the falling Dendrobium. At the same time, the spring 302 between the guide rail 301 and the fixed plate 303 provides elastic support for the screen 304. Under the action of vibration, the spring releases the elastic force, driving the screen 304 to oscillate slightly along the guide rail 301, forming a secondary vibration, which significantly enhances the screening force and efficiency. During this process, fine and qualified Dendrobium powder falls through the screen 304 and is collected in the drawer 305 at the bottom, while unqualified coarse particles remain on the screen 304. The side baffle 306 effectively prevents the material from leaking from the side of the collection frame 211 during the screening process. When it is necessary to clean the retained coarse particles or take out the drawer 305, the baffle 306 can be opened for operation. This not only ensures the effective stratification of Dendrobium, but also greatly improves the screening efficiency of Dendrobium.

[0031] like Figure 2 and Figure 4 As shown, a protrusion 4 is fixedly connected to the top of the fixing ring 204, a positioning ring 5 is rotatably connected to the outer wall of the fixing rod 203, a positioning plate 6 is fixedly connected to the outer wall of the positioning ring 5, and the side of the positioning plate 6 away from the positioning ring 5 is fixedly connected to the inner wall of the fixing tank 201. A scraper 7 is provided at the bottom of the positioning plate 6. When crushing Dendrobium, the protrusion 4 allows Dendrobium to enter the grinding area better, and the scraper 7 at the bottom of the positioning plate 6 scrapes away any Dendrobium residue on the protrusion 4, thus scraping it into the grinding area, ensuring the continuity of grinding and preventing the accumulation of medicinal materials from affecting the grinding effect.

[0032] like Figure 4As shown, extension blocks 8 are fixedly connected to both sides of the storage frame 211, and extension columns 9 are fixedly connected to one side of each of the two extension blocks 8. Two clamps 10 are hinged to one side of the baffle 306. When it is necessary to clean the large Dendrobium particles remaining on the sieve 304, the clamps 10 on one side of the baffle 306 can be loosened, allowing the baffle 306 to rotate around the hinge point and open. The sieve 304 can then be pulled out, and the large Dendrobium particles can be poured back into the fixed container 201 for secondary grinding, which greatly improves the cleaning efficiency of Dendrobium grinding.

[0033] like Figure 2 As shown, multiple guide plates 11 are fixedly connected to the inner wall of the feeding frame 214, and the multiple guide plates 11 are evenly distributed along the length direction of the feeding frame 214. Through the guide plates 11 in the feeding frame 214, the Chinese medicinal materials can be poured into the fixed tank 201 evenly and orderly, avoiding problems such as the accumulation or uneven distribution of Dendrobium due to the excessive pouring speed.

[0034] like Figure 5 As shown, the inner walls of the three grinding rings 206 are each provided with multiple grooves 12, which are evenly distributed along the height of the grinding rings 206. During the grinding process, the Dendrobium is squeezed and rubbed between the grinding rollers 205 and the grinding rings 206. The grooves 12 increase the contact area between the grinding rings 206 and the medicinal material, which not only allows the Dendrobium to be ground more thoroughly, but also improves the fineness of the grinding.

[0035] like Figure 4 As shown, an observation frame 13 is provided on the outer wall of the fixed tank 201, and a tempered glass 14 is provided inside the observation frame 13. Through the observation frame 13 and the tempered glass 14 provided on the fixed tank 201, the state changes of the Dendrobium inside the fixed tank 201 during the grinding process can be monitored in real time, ensuring that the molding quality is controllable.

[0036] Specifically, in use, this fine grinding device works as follows: Dendrobium is poured into the fixed tank 201 through the feed frame 214. The servo motor 202 starts, driving the grinding roller 205 on the fixed rod 203 to rotate. The Dendrobium is squeezed and ground between the grinding roller 205 and the grinding ring 206. The gap between the grinding roller 205 and the grinding ring 206 forms a multi-stage pulverization zone, thus achieving multiple grinding of the Dendrobium. Subsequently, the blower 209 blows out cold air, which cools the fixed tank 201 through the spiral guide pipe 208. The heat-absorbing airflow is discharged through the air outlet pipe 210. At the same time, water is injected into the tank 1 through the water injection pipe 212. The water source, together with the cold air in the spiral guide pipe 208, implements a double high-efficiency cooling of the fixed tank 201, effectively suppressing the heat generated during the grinding process (such as...). Figures 2-4(As shown); the ground Dendrobium falls through funnel 207 onto the surface of sieve 304. The sieve 304 vibrates due to the impact of the falling Dendrobium. Simultaneously, the spring 302 between guide rail 301 and fixed plate 303 provides elastic support for the sieve 304. Under vibration, the spring releases its elasticity, driving the sieve 304 to oscillate slightly along guide rail 301, forming secondary vibration, significantly enhancing the screening force and efficiency. During this process, fine, qualified Dendrobium powder falls through sieve 304 into the bottom drawer 305 for collection, while substandard coarse particles remain on sieve 304. The side baffle 306 effectively prevents material leakage from the side of the collection frame 211 during screening. When it is necessary to clean the retained coarse particles or remove drawer 305, the baffle 306 can be easily opened for operation (e.g., Figure 3 and Figure 4 (As shown in the figure); it greatly improves the grinding efficiency of Dendrobium.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
