Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine powder screening, in particular to a screening device for processing traditional Chinese medicine powder. Background Art

[0002] Traditional Chinese medicine, also known as traditional Chinese drugs, refers to substances used for preventing and treating diseases, as well as health care under the guidance of traditional Chinese medicine theory. These substances mainly come from plants, animals and minerals in nature. After being processed by decocting, they can be used alone or formulated into prescriptions for people to use. The screening device for processing traditional Chinese medicine powder is a mechanical device specifically used for screening traditional Chinese medicine powder. Its design purpose is to screen the medicinal powder in the production of traditional Chinese medicine to ensure the fineness and uniformity of the medicinal powder, thereby improving the quality of traditional Chinese medicine preparations.

[0003] In the prior art, when most screening devices for processing traditional Chinese medicine powder feed traditional Chinese medicine, the amount of traditional Chinese medicine fed cannot be controlled. When the feeding amount is too large, the medicinal powder on the sieve will accumulate too thickly, making the medicinal powder at the bottom unable to fully contact the sieve during the screening process, thus reducing the screening efficiency. Excessive medicinal powder is likely to block the pores of the sieve, especially for traditional Chinese medicine powder containing more fibers, which will increase the frequency of cleaning and maintenance and further reduce the screening efficiency. Therefore, a screening device for processing traditional Chinese medicine powder is proposed to solve the above problems. Summary of the Utility Model

A power assembly for driving the subsequent components is fixedly connected to the inner wall of the protection box 20. The power assembly includes a second motor 21, which is the driving source. The outside of the second motor 21 is fixedly connected to the inner wall of the protection box 20, enabling the second motor 21 to operate stably. The driving end of the second motor 21 is fixedly connected to a rotating shaft 22. The force of the rotation of the driving end of the second motor 21 is transmitted to the subsequent components through the rotating shaft 22. A circular plate 23 is fixedly connected to the front side of the power assembly. The front side of the rotating shaft 22 is fixedly connected to the inner wall of the circular plate 23. The rotating shaft 22 transmits the rotating force to the circular plate 23. A fixed plate 24 is rotatably connected to the front side of the circular plate 23 for driving the subsequent components to slide left and right. The left end of the fixed plate 24 is rotatably connected to an opening block 25. Due to the restriction of the opening block 25 and the circular plate 23, the fixed plate 24 can rotate left and right reciprocally.

[0040] Refer to Figure 2 , Figure 7 and Figure 8 , an arc-shaped block 27 is fixedly connected to the left side of the opening block 25. A limiting column 28 is rotatably connected to the inner wall of the arc-shaped block 27. The arc-shaped block 27 can rotate reciprocally around the limiting column 28 as the center point. A support plate 26 is fixedly connected to the rear side of the limiting column 28 to provide a supporting force for the limiting column 28. The right side of the support plate 26 is fixedly connected to the right side inner wall of the screening box 1 to provide a supporting force for the support plate 26. Sliding rods 29 are slidably connected to both the upper and lower ends of the arc-shaped block 27 to push the sliding rods 29 to slide left and right. An arc-shaped plate 30 is fixedly connected to the rear side of the sliding rods 29 to restrict the sliding rods 29 and prevent them from slipping. A connecting plate 31 is fixedly connected to the front side of the sliding rods 29 to push the connecting plate 31 to slide. A support block 32 is fixedly connected to the left side of the connecting plate 31, thereby pushing the support block 32 to slide. The relatively far sides of the two support blocks 32 are respectively fixedly connected to the relatively close sides of the two screening plates 33, and then the screening plates 33 are pushed to slide left and right to screen the medicinal powder.

[0041] Refer to Figure 1 , Figure 6 and Figure 9, both the front and rear ends of the screening box 1 are fixedly connected with two fixed shafts 36. A spring 37 is sleeved outside the fixed shaft 36 to limit the spring 37 so that the spring 37 can be evenly stressed. A sliding plate 38 is slidably connected to the outside of the fixed shaft 36 so that the sliding plate 38 can slide vertically. Trapezoidal blocks 39 are fixedly connected to the adjacent sides of every two sliding plates 38. Following the limit posts 28, the sliding rod 29 can slide vertically. Two strip-shaped openings 35 are provided on both the front and rear sides of the inner wall of the screening box 1 to limit the movement of subsequent components. Two falling plates 40 are fixedly connected to both the left and right sides of the screening box 1 to export the screened medicinal powder. A collection box 41 is slidably connected to the bottom end of the screening box 1. The outside of the fixed shaft 36 is slidably connected to the inner wall of the trapezoidal block 39 to limit the trapezoidal block 39 so that the trapezoidal block 39 can slide. Impact plates 42 are fixedly connected to the opposite sides of every two sliding plates 38.

[0042] Working principle: We pour all the medicinal powder into the interior of the feeding frame 2, and then the medicinal powder falls into the interior of the collection frame 3. The medicinal powder inside the collection frame 3 will penetrate and fall onto the screening plate 33 inside the screening box 1. At this time, the driving motor 1 drives the rotating shaft 7 to rotate, which in turn drives the rotating plate 8 to rotate, and then drives the rotating column 9 to rotate. At this time, as the rotating column 9 rotates around the rotating shaft 7 as the center, it can push the hollow plate 10 to slide back and forth left and right, and then drive the collection frame 3 to slide left and right. As the collection frame 3 slides, when it no longer slides to be perpendicular to the feeding port of the feeding frame 2, the collection frame 3 will drive the sealing plate 4 to block the feeding port of the feeding frame 2. At this time, the collection frame 3 is in contact with the inner wall of the screening box 1, so as to block the medicinal powder inside the collection frame 3. When the collection frame 3 reciprocates left and right, after the collection frame 3 is perpendicular to the top opening of the screening box 1 again, the medicinal powder inside the collection frame 3 will penetrate the collection frame 3 again and fall onto the screening plate 33 inside the screening box 1, so as to achieve quantitative feeding, avoiding excessive feeding amount resulting in too thick a pile of medicinal powder on the sieve mesh, making the medicinal powder at the bottom unable to fully contact the sieve mesh during the screening process, and excessive medicinal powder will block the pores of the sieve mesh, especially for traditional Chinese medicinal powder with more fibers, both too much and too little will lead to a reduction in screening efficiency; at the same time, the rotating shaft 7 will also drive the driving wheel 11 to rotate, which in turn drives the belt 12 to rotate. The driven wheel 16 is driven to rotate by the friction of the belt 12, and the driven wheel 16 will drive the rotating column 15 to rotate. The rotating column 15 drives the rotating blades 14 to rotate, and the dust inside the screening box 1 is extracted and will pass through the filter plate 17 to filter out the dust in the air, so as to centrally process the dust and improve the working environment;

[0043] After the powder falls onto the screening plate 33, the driving motor two 21 drives the rotating shaft 22 to rotate, then drives the circular plate 23 to rotate, thereby driving the fixing plate 24 to rotate, and then the opening block 25 drives the arc block 27 to rotate left and right around the limit post 28, so that the arc block 27 can drive the sliding rod 29 to slide left and right, thereby driving the connecting plate 31 to slide left and right alternately, and then driving the support block 32 to slide left and right alternately. The screening plate 33 is driven to slide left and right alternately by the support block 32 to achieve multiple screening of the powder, so that powders of different sizes can be separated, thereby improving the product quality. At the same time, during the sliding process of the two screening plates 33, four square blocks 34 will be driven to slide. There will be a trapezoidal block 39 between every two square blocks 34. When the screening plate 33 drives the square block 34 to slide left and right, it will abut against the trapezoidal block 39. At this time, due to the inclined design of the trapezoidal block 39, the trapezoidal block 39 will push the sliding plate 38 to contract and slide outside the fixed shaft 36 after being stressed, and then squeeze the spring 37, so that the spring 37 can store elastic potential energy, and then give the sliding plate 38 a force in the opposite direction to push the striking plate 42 to reset and strike the screening plate 33, so that the powder stuck inside the inner wall of the screening plate 33 will bounce up after being vibrated, avoiding the powder just getting stuck inside the screening plate 33 and affecting the screening effect, thereby extending its service life.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
