Technical Field
[0001] The present invention relates to the technical field of grinding, and particularly to a fine grinding device for traditional Chinese medicine. Background Art
[0002] Traditional Chinese medicine, as a treasure of traditional Chinese medicine in our country, has a long history of development. In the preparation of traditional Chinese medicine, fine grinding of traditional Chinese medicine is a very important link. Fine grinding can make traditional Chinese medicine release active ingredients better, improve the efficacy and utilization rate.
[0003] At present, in the process of fine grinding of traditional Chinese medicine, various drugs with different properties are usually ground together. However, there are certain problems with existing traditional Chinese medicine grinding devices. Most grinding equipment, when grinding a mixture of various drugs, due to differences in the specific gravity, particle size, etc. of different drugs, especially traditional Chinese medicine with a relatively large specific gravity, will quickly fall to the lower side of the grinding cylinder during the grinding process. Once the traditional Chinese medicine accumulates on the lower side, it will cause uneven distribution of traditional Chinese medicine in the grinding cylinder, resulting in most of the grinding work being concentrated on the traditional Chinese medicine in the lower part, and the grinding degree of traditional Chinese medicine in other positions is insufficient, causing uneven overall grinding. This not only affects the grinding quality, but also makes the active ingredients of the drug not released completely, reducing the subsequent efficacy of traditional Chinese medicine.
[0004] Therefore, there is an urgent need for a fine grinding device for traditional Chinese medicine that can solve the problem of uneven distribution of traditional Chinese medicine and achieve uniform grinding. The fine grinding device for traditional Chinese medicine of the present invention is developed under such a background. Through a specially designed spiral blade and grinding wheel structure, it effectively solves the problem of uneven grinding existing in the prior art. Summary of the Invention
[0005] Aiming at the problems existing in the prior art, the present invention provides a fine grinding device for traditional Chinese medicine to solve the problems of uneven distribution of traditional Chinese medicine and achieving uniform grinding as mentioned in the above background art.
[0006] The present invention is implemented as follows. A fine grinding device for traditional Chinese medicine includes a grinding cylinder. The inner cavity of the grinding cylinder is cylindrical.

[0007] Preferably, there are several fixed shafts, and several fixed shafts are arranged at equal intervals in a ring relative to the axis of the spiral blade. Several grinding wheels are arranged on each fixed shaft, and at least part of the grinding wheels are located in the spaces between the spiral blades.

[0009] As a preferred embodiment of the present invention, the driving shaft includes a driving member and a round shaft; the round shaft is rotatably connected to the upper wall and the lower wall through a bearing, and the driving member is fixedly connected to the lower end of the round shaft. For example, the driving member is set as a motor.
[0010] As a preferred embodiment of the present invention, the drive shaft also includes: a load-bearing ring fixedly connected to the circular shaft, an elastic member fixedly connected to the lower side of the load-bearing ring, a sleeve fixedly connected to the lower end of the elastic member, and the spiral blade fixedly connected to the outer side of the sleeve.

Specific embodiments
[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail with reference to the accompanying drawings.
[0029] The structure of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] As Figures 1 to 9 shown, a traditional Chinese medicine fine grinding device provided by an embodiment of the present invention includes a grinding cylinder 1. The inner cavity of the grinding cylinder 1 is cylindrical. A feed hopper 2 is provided on the upper side of the grinding cylinder 1, and a discharge pipe 3 is provided on the lower side of the grinding cylinder 1. A driving shaft is provided inside the grinding cylinder 1. The driving shaft is rotatably connected to the grinding cylinder 1 and is coaxially arranged with the grinding cylinder 1. A spiral blade 5 is circumferentially connected to the driving shaft. A fixed shaft 6 is fixedly connected to the spiral blade 5. A grinding wheel 7 is rotatably connected to the fixed shaft 6. The edge of the grinding wheel 7 is attached to the inner surface of the side wall of the grinding cylinder 1.
[0031] Through this setting, when it is necessary to grind traditional Chinese medicine, a variety of medicines are put into the grinding cylinder 1 from the feed hopper 2. The driving shaft starts to rotate. Since the driving shaft and the grinding cylinder 1 are coaxially arranged, the rotation of the driving shaft will drive the spiral blade 5 to rotate. The rotating spiral blade 5 will push the traditional Chinese medicine (including heavy and light ones) falling to the lower side of the grinding cylinder 1 upward, so that the traditional Chinese medicine is in a more uniform distribution state in the grinding cylinder 1. As the traditional Chinese medicine moves, since the edge of the grinding wheel 7 is attached to the inner surface of the side wall of the grinding cylinder 1, when the traditional Chinese medicine falls from the edge of the spiral blade 5, the edge of the grinding wheel 7 and the inner surface of the side wall of the grinding cylinder 1 are squeezed and ground, thereby realizing uniform grinding of the traditional Chinese medicine. The ground medicine is discharged from the discharge pipe 3 on the lower side of the grinding cylinder 1. Specifically, the surface of the grinding wheel 7 is covered with wear-resistant material, which increases the friction with the medicinal materials and makes the grinding process more efficient.
[0032] Specifically, there are several fixed shafts 6, and several fixed shafts 6 are arranged in an annular and equidistant manner relative to the axis of the spiral blade 5; each fixed shaft 6 is provided with several grinding wheels 7, and the grinding wheels 7 are at least partially located in the spacing of the spiral blade 5. When the driving shaft drives the spiral blade 5 to rotate, multiple fixed shafts 6 distributed in an annular and equidistant manner rotate synchronously. Several grinding wheels 7 installed on each fixed shaft 6 move with the shaft, and their edges keep in contact with the inner wall of the grinding cylinder 1. Since the grinding wheel 7 is partially embedded in the spacing of the spiral blade 5, while the spiral blade 5 pushes the Chinese medicine upward, the lower side of the grinding wheel 7 will squeeze and shear the Chinese medicine on the surface of the spiral blade 5, thereby achieving multi-dimensional grinding. When the spiral blade 5 rotates, the heavier Chinese medicine is continuously lifted upward, and the grinding wheel 7 not only grinds the Chinese medicine during the rotation process, but also pushes away the Chinese medicine adhering to the surface of the spiral blade 5 through its own rotation to prevent the Chinese medicine from accumulating and clogging. The design of the grinding wheel 7 being embedded in the spacing of the spiral blade 5 allows the Chinese medicine to be repeatedly "rolled in and squeezed out" during the lifting process, forming a cyclic grinding path. And the multiple grinding wheels 7 on each fixed shaft 6 are distributed along the axial direction, and the grinding wheels 7 of adjacent fixed shafts 6 are arranged alternately in the spacing of the spiral blades 5. This design enables the grinding coverage to form a multi-layer grinding area from the bottom to the top of the grinding cylinder 1, ensuring that the Chinese medicines at different heights and different positions can be fully processed.
[0033] Specifically, the grinding cylinder 1 includes a support member 11, a side cylinder 12, a bottom wall 13 and an upper wall 14; the support member 11 is a cylinder, the bottom wall 13 is fixedly connected to the upper side of the cylinder, a discharge port is provided on the bottom wall 13, the bottom wall 13 and the discharge pipe 3 are fixedly connected, and the discharge port and the discharge pipe 3 are aligned; the side cylinder 12 is fixedly connected to the upper side of the bottom wall 13; the upper wall 14 is fixedly connected to the upper end of the side cylinder 12, a feed port is provided on the upper wall 14, the feed hopper 2 is fixedly connected to the upper wall 14, and the lower end of the feed hopper 2 is aligned with the feed port.
[0034] The driving shaft includes a driving member 41 and a round shaft 42; the round shaft 42 is rotatably connected to the upper wall 14 and the lower wall through a bearing, and the driving member 41 is fixedly connected to the lower end of the round shaft 42. For example, the driving member 41 is configured as a motor.
[0035] The drive shaft further includes: a bearing ring 43 fixedly connected to the circular shaft 42 , an elastic member 44 fixedly connected to the lower side of the bearing ring 43 , a sleeve 45 fixedly connected to the lower end of the elastic member 44 , and the spiral blade 5 fixedly connected to the outer side of the sleeve 45 .
[0036] A number of rubber sheets 8 arranged at equal intervals are provided below the feed inlet, and rubber strips 9 are provided on the rubber sheets 8; when the spiral blade 5 is in the upper working position, the uppermost grinding wheel 7 can push the rubber sheet 8; a push rod 10 is provided above the rubber strip 9, and the upper half of the push rod 10 is located in the feed hopper 2.
[0037] With this setting, it has the function of automatically adjusting the amount of traditional Chinese medicine in the grinding cylinder 1. Specifically, when the amount of traditional Chinese medicine in the grinding cylinder 1 is normal, there is traditional Chinese medicine on the spiral blade 5, so the spiral blade 5 moves downward (stretching the elastic member 44), and at this time the grinding wheel 7 will not push the rubber sheet 8. When the rubber sheet 8 is not pushed, the traditional Chinese medicine is blocked by the rubber strip 9 and will not fall into the grinding cylinder 1. When there is less traditional Chinese medicine on the spiral blade 5, under the pulling of the elastic member 44, the spiral blade 5 rises, so that the grinding wheel 7 pushes the rubber sheet 8. At this time, the traditional Chinese medicine can fall into the grinding cylinder 1, and after reaching the preset amount, the spiral blade 5 is automatically pressed down by the traditional Chinese medicine, so that it no longer pushes the rubber sheet 8, and thus the feeding stops. And when the rubber sheet 8 is pushed, the push rod 10 also shakes accordingly, thus preventing the feed hopper 2 from being blocked.
[0038] Furthermore, a dust suction pipe 15 is provided on the grinding cylinder 1, a dust suction hole 16 is provided on the dust suction pipe 15, and the dust suction pipe 15 is located in the gap between the rubber sheets 8. With this setting, impurity removal can be carried out while feeding, and the dust suction pipe 15 is connected to a vacuum cleaner.
[0039] Furthermore, a sieve plate 17 is provided at the bottom of the grinding cylinder 1. The sieve plate 17 is a circular sieve plate 17. A circular hole 18 is provided in the middle of the sieve plate 17. The sieve plate 17 is sleeved on the circular shaft 42 through the circular hole 18, and the sieve plate 17 is located below the spiral blade 5. With this setting, in use: the rotation of the circular shaft 42 can push the sieve plate 17 to rotate, so as to screen the traditional Chinese medicine. The qualified traditional Chinese medicine can pass through the sieve plate 17, and the unqualified traditional Chinese medicine will be pushed up again by the spiral blade 5 and ground again. With this setting, on the one hand, the circular shaft 42 provides power for the sieve plate 17, and on the other hand, the spiral blade 5 can clean the upper surface of the sieve plate 17 to prevent blockage. With this setting, if the sieve plate 17 is blocked, the spiral blade 5 will push the traditional Chinese medicine on the sieve plate 17 upward. Since there is traditional Chinese medicine on the spiral blade 5, the spiral blade 5 is always in the lower working position, so the feed hopper 2 will not continue to feed. At this time, by continuing to grind, the blockage problem can be automatically solved. Preferably, a baffle 19 is fixedly connected to the lower side of the sieve plate 17. The push rod 10 can push the traditional Chinese medicine passing through the sieve plate 17 into the discharge pipe 3.
[0040] The working principle of the present invention:
[0041] When it is necessary to grind traditional Chinese medicine, various kinds of medicine are put into the grinding cylinder 1 from the feed hopper 2. The drive shaft starts to rotate, driving the spiral blade 5 to rotate. The rotating spiral blade 5 will push the traditional Chinese medicine falling to the lower side of the grinding cylinder 1 upward, making the traditional Chinese medicine in a more uniform distribution state in the grinding cylinder 1. With the movement of the traditional Chinese medicine, since the edge of the grinding wheel 7 is in contact with the inner surface of the side wall of the grinding cylinder 1, during the process of the traditional Chinese medicine falling from the edge of the spiral blade 5, the edge of the grinding wheel 7 and the inner surface of the side wall of the grinding cylinder 1 are squeezed and ground, so as to realize the uniform grinding of traditional Chinese medicine. The ground medicine is discharged from the discharge pipe 3 on the lower side of the grinding cylinder 1. Specifically, the surface of the grinding wheel 7 is covered with wear-resistant materials, which increases the friction with the medicinal materials and makes the grinding process more efficient. When traditional Chinese medicine is ground together in the past, the heavy traditional Chinese medicine will quickly fall to the lower side of the grinding cylinder 1, resulting in uneven grinding. The spiral blade 5 can continuously push the heavy traditional Chinese medicine at the bottom to the top, ensuring that every part of the medicinal materials can be fully ground, thus improving the overall grinding quality. At the same time, this design also reduces the wear of the grinding wheel 7 caused by the accumulation of traditional Chinese medicine and extends the service life of the equipment.
