Specific embodiments

[0019] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] As Figure 1As shown in FIG. 4, an embodiment of the present utility model provides a traditional Chinese medicine grinding device, which includes a bottom plate 1, guide rods 4 and a screening assembly. Two support columns 2 are symmetrically arranged on the top of the bottom plate 1. A rolling table 3 is fixedly installed between the two support columns 2. A grinding groove is formed on the rolling table 3. The bottom of the grinding groove is a semi-circle. A discharge port for discharging the medicinal materials is formed at the bottom of the grinding groove. There are two guide rods 4, and both of the two guide rods 4 are fixedly arranged on the top of one of the support columns 2. An installation plate 5 is slidably sleeved on the two guide rods 4. A first spring 6 is arranged between the bottom of the installation plate 5 and the support column 2. A first motor 7 is fixedly arranged on the installation plate 5. A vertical groove communicating with the grinding groove is formed on the side wall of the rolling table 3 close to the first motor 7. The output end of the first motor 7 passes through the vertical groove and is fixedly provided with a rolling roller 8. The screening assembly is arranged between the two support columns 2 and directly below the discharge port, and the screening assembly screens the medicinal materials discharged from the discharge port. During operation, the medicinal materials to be ground are put into the grinding groove from above the rolling table 3, and then the first motor 7 is started. The first motor 7 drives the rolling roller 8 to rotate, so that the rolling roller 8 grinds the medicinal materials. Since the first motor 7 is fixed on the installation plate 5, and the first spring 6 is arranged at the bottom of the installation plate 5, when the first motor 7 operates, the reaction force generated by its rotation will cause the motor itself to vibrate and shake. The guide rods 4 guide the displacement of the installation plate 5, so that the first motor 7 generates a displacement with a small distance in the vertical direction, thereby changing the distance between the rolling wheel and the grinding groove. When this distance increases, it is more conducive for the medicinal materials to enter below the rolling roller 8. As the installation plate 5 is reset under the pulling of the first spring 6, the rolling roller 8 generates a downward pounding force, thereby accelerating the grinding and milling of the medicinal materials. Specifically, a valve is arranged at the discharge port at the bottom of the grinding groove. After grinding for a period of time, the valve is opened to allow the ground medicinal materials to be discharged from the discharge port and screened by the screening assembly. Some medicinal materials that are not ground fine enough are screened out for secondary grinding. By making the rolling roller 8 rotate and move up and down, the medicinal materials can quickly enter below the rolling roller 8, and the medicinal materials are rubbed, squeezed and pounded by the rolling roller 8, so that they can be quickly ground into fine powder, and the grinding efficiency is improved.

[0021] As Figure 1As shown in FIG. 4, further, the screening assembly includes: a filter screen plate 9. Slide bars 10 are fixedly provided at the four corners of the filter screen plate 9. Each slide bar 10 is slidably connected to the bottom of the rolling table 3. A retaining bar 11 is provided on the top of the filter screen plate 9. A driving assembly for driving the filter screen plate 9 to reciprocate up and down in the vertical direction is provided on one of the support columns 2. Specifically, chutes corresponding to the slide bars 10 are opened at the four corners of the bottom of the rolling table 3. One end of each slide bar 10 away from the filter screen plate 9 is slidably connected to the corresponding chute, and a limiting member is provided on the slide bar 10 to prevent the slide bar 10 from completely disengaging from the chute. After the ground medicinal materials are discharged from the discharge port, these medicinal materials fall onto the filter screen plate 9. The filter screen plate 9 screens the ground medicinal materials, leaving the over-sized medicinal material particles on the filter screen plate 9. During this process, the driving assembly drives the filter screen plate 9 to reciprocate up and down, causing the filter screen plate 9 to vibrate, thereby accelerating the screening of the ground medicinal materials by the filter screen plate 9. The retaining bar 11 can prevent the medicinal materials from falling to the outside from the edge of the filter screen plate 9.

[0022] As Figure 1 As shown in FIG. 3, further, the driving assembly includes: a second motor 12. The second motor 12 is fixedly provided on one of the support columns 2. A cam 13 is provided at the output end of the second motor 12. The outer wall of the cam 13 is in close contact with the bottom of the filter screen plate 9. In this embodiment, the second motor 12 drives the cam 13 to rotate. The cam 13 pushes the filter screen plate 9 towards the rolling table 3. Until the cam 13 rotates a certain angle, the cam 13 no longer pushes the filter screen plate 9 upward. The filter screen plate 9 remains in close contact with the outer wall of the cam 13 under the action of gravity and thus moves downward. In this way, the filter screen plate 9 reciprocates to generate vibration in the vertical direction, accelerating its screening efficiency for the medicinal materials. Preferably, a driving assembly can be provided on each support column 2.

[0023] As Figure 3 As shown, further, one end of a second spring 14 is also fixedly provided on the top of the filter screen plate 9. The other end of the second spring 14 is fixedly connected to the bottom of the grinding table. In this embodiment, there are four second springs 14. Each second spring 14 is sleeved on the corresponding slide bar 10. The second spring 14 can push the filter screen plate 9 to always remain in a state of being in close contact with the outer wall of the cam 13.

[0024] As Figure 4As shown in Fig. -5, further, it further includes a mounting block 15. The mounting block 15 is fixedly arranged in the grinding groove. An installation groove is formed at the bottom of the mounting block 15. A sliding plate 16 is slidably arranged in the installation groove. A third spring 17 is connected between the sliding plate 16 and the installation groove. A plurality of scraping blades 18 are arranged on the side of the sliding plate 16 away from the third spring 17. During the long-term rolling of the medicinal materials by the rolling roller 8, especially after the outer wall of the rolling roller 8 becomes rough, it is very easy for the medicinal materials to adhere to the rolling roller 8. These medicinal materials adhere to the outer wall of the rolling roller 8 for a long time and cannot be discharged from the discharge port. On the one hand, it affects the working efficiency of the rolling roller 8, and on the other hand, it may cause the deterioration of this part of the medicinal materials. The sliding plate 16 is connected to the mounting block 15 through the third spring 17, so that the sliding plate 16 moves towards the rolling roller 8 under the drive of the third spring 17, so that the scraping blades 18 on the sliding plate 16 scrape the residual medicinal materials on the outer wall of the rolling roller 8, clean the medicinal materials in time, ensure the working efficiency of the rolling roller 8, and also avoid the growth of harmful substances such as bacteria after the long-term residue of this part of the medicinal materials.

[0025] As Figure 4 shown in Fig. -5, further, there are two scraping blades 18. The two scraping blades 18 are symmetrically arranged on both sides of the sliding plate 16. Both scraping blades 18 are inclined towards the ends away from each other. In this embodiment, there are two scraping blades 18. The two scraping blades 18 are arranged on both sides of the sliding plate 16. In this way, when the rolling roller 8 moves up and down, it will not rigidly contact the cutting edges of the scraping blades 18, avoiding damage to the cutting edges of the scraping blades 18. When the scraping blades 18 are pushed by the rolling roller 8, the scraping blades 18 can move into the installation groove along with the sliding plate 16 against the elastic force of the third spring 17, extending the service life of the scraping blades 18.

[0026] As Figure 1 shown in Fig. -4, further, it further includes a collection table 19. The collection table 19 is fixedly arranged between the two support columns 2. An arc-shaped depression is formed at the top of the collection table 19. A material dropping port is arranged at the bottom of the collection table 19. The material dropping port is communicated with the arc-shaped depression. The sieved medicinal materials will fall onto the collection table 19. The arc-shaped depression of the collection table 19 guides the medicinal materials scattered on the collection table 19, gathers this part of the medicinal materials through its arc-shaped depression structure and discharges them from the material dropping port. In this embodiment, a collection dish is also arranged directly below the material dropping port to collect the medicinal materials.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
