Description

Technical Field

[0001] This application relates to the field of dust removal technology for grain counting machines, and in particular to a dust removal mechanism for an automatic grain counting machine for traditional Chinese medicine. Background Technology

[0002] After the production of solid Chinese medicine granules and pills is completed, the pills need to be bottled and packaged. During the bottling process, in order to ensure that the number of pills in each bottle is the same, an automatic Chinese medicine counting machine is usually used. An automatic Chinese medicine counting machine is a device that utilizes the photoelectric effect principle, using an infrared counter and an FPGA high-speed microprocessor for precise counting. It is suitable for various solid Chinese medicine granules, such as soft and hard capsules, tablets, and pills, and can efficiently and accurately complete the counting task.

[0003] In related technologies, during the use of automatic Chinese medicine counting machines, dust and impurities inevitably mix into the Chinese medicine granules during the production process. If these dusts are not removed in time, they will not only affect the purity of the Chinese medicine and reduce the quality of the medicine, but may also affect the key components of the automatic Chinese medicine counting machine, such as the infrared counter. When a lot of dust and impurities accumulate on the surface of the infrared counter, it will reduce its counting accuracy and thus interfere with the entire filling process.

[0004] Therefore, we propose a dust removal mechanism for an automatic Chinese medicine counting machine to solve the above problems. Utility Model Content

[0005] This application aims to address the problem that dust and impurities mixed in with traditional Chinese medicine granules not only affect the purity of the medicine and reduce its quality, but may also affect key components of automatic traditional Chinese medicine counting machines, such as infrared counters. When a large amount of dust and impurities accumulate on the surface of the infrared counter, it will reduce its counting accuracy. This application provides a dust removal mechanism for an automatic traditional Chinese medicine counting machine.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a dust removal mechanism for an automatic Chinese medicine counting machine, comprising a Chinese medicine counting and filling cylinder fixedly mounted on the automatic Chinese medicine counting machine and a dust removal assembly disposed on the Chinese medicine counting and filling cylinder. A medicine inlet pipe is fixedly installed at the top of the Chinese medicine counting and filling cylinder, and a filling and dispensing pipe is fixedly installed at the bottom of the Chinese medicine counting and filling cylinder. An infrared counter is fixedly installed on the inner wall of the Chinese medicine counting and filling cylinder. The dust removal assembly includes a dust collection box, an air pump, an air extraction pipe, an L-shaped dust suction pipe, an annular dust suction pipe, a first dust suction head, a second dust suction head, and a third dust suction head. The dust box is fixedly installed on the outer wall of the Chinese medicine counting container. The air pump is fixedly installed on the outer wall of the dust box away from the Chinese medicine counting container. One end of the air suction pipe is fixedly connected to the suction end of the air pump, and the other end of the air suction pipe extends into the dust box. The L-shaped suction pipe is fixedly installed on the top of the dust box, and one end of the L-shaped suction pipe extends into the dust box. The annular suction pipe is fixedly installed on the inner wall of the Chinese medicine counting container and located above the infrared counter. The other end of the L-shaped suction pipe is fixedly connected to the annular suction pipe. Suction head one, suction head two, and suction head three are all fixedly installed on the annular suction pipe.

[0007] By adopting the above technical solution, the inlet pipe is used to introduce Chinese medicine granules into the Chinese medicine counting and filling cylinder, and the filling outlet pipe is used to transport the counted Chinese medicine granules out of the Chinese medicine counting and filling cylinder to complete the filling process. The infrared counter is used to count the Chinese medicine granules passing through the Chinese medicine counting and filling cylinder, providing a quantitative basis for Chinese medicine filling, accurately counting the number of Chinese medicine granules, and ensuring the accuracy of the filling quantity. The dust collection box is used to centrally store dust, avoiding secondary diffusion of dust in the working environment and keeping the working area clean. The air pump is used to extract the air from the dust collection box, creating negative pressure inside the dust collection box, which in turn creates negative pressure inside the L-shaped suction pipe, the ring suction pipe, suction head one, suction head two, and suction head three. During the counting of Chinese medicine granules, the dust and impurities in the Chinese medicine granules can be sucked into the dust collection box.

[0008] Optionally, the dust removal assembly also includes a dust filter and activated carbon particles. The dust filter is fixedly installed in the dust collection box, one end of the L-shaped suction pipe is located on one side of the dust filter, and the activated carbon particles are stored in the dust collection box and located on the other side of the dust filter.

[0009] By adopting the above technical solution, the dust filter is used to perform preliminary filtration and purification of the air containing dust impurities entering the dust collection box, intercepting and blocking larger dust impurities. Activated carbon particles are used to perform secondary adsorption and purification of the air after preliminary filtration by the dust filter, removing fine dust impurities.

[0010] Optionally, the dust filter is inclined, and a baffle is fixedly installed at one end of the exhaust pipe inside the dust collection box.

[0011] By adopting the above technical solution, the dust filter is designed to be inclined, which can effectively reduce the clogging of the filter holes on the dust filter. The baffle is used to prevent activated carbon particles from entering the L-shaped dust suction pipe.

[0012] Optionally, the number of vacuum heads one, two, and three is set to multiple and evenly distributed, with vacuum head one inclined upwards, vacuum head two horizontally, and vacuum head three inclined downwards.

[0013] By adopting the above technical solution, dust and impurities in various locations inside the Chinese medicine counting container can be extracted from different directions, improving the comprehensiveness of dust removal.

[0014] Optionally, an annular baffle is fixedly installed inside the Chinese medicine counting container, and the annular dust suction pipe, dust suction head one, dust suction head two and dust suction head three are all located inside the annular baffle.

[0015] By adopting the above technical solution, the annular baffle can block the Chinese medicine particles and ensure that the dust and impurities mixed with the Chinese medicine particles can pass smoothly through the mesh on the annular baffle, thus ensuring that the dust removal operation is carried out smoothly.

[0016] Optionally, an isolation ring seat is fixedly installed inside the Chinese medicine counting container. The isolation ring seat is located between the annular baffle and the infrared counter, and the longitudinal section of the isolation ring seat is trapezoidal.

[0017] By adopting the above technical solution, the trapezoidal longitudinal section of the isolation ring seat helps guide the Chinese medicine granules to fall smoothly, while also playing a certain role in isolation, effectively preventing dust and impurities from affecting the counting accuracy of the infrared counter and ensuring the cleanliness of the working environment of the infrared counter.

[0018] Optionally, the exhaust end of the air pump is fixedly connected to an air outlet pipe, and an annular air distribution plate located below the infrared counter is fixedly installed inside the Chinese medicine counting cylinder. The top of the annular air distribution plate has several evenly distributed air holes, and the end of the air outlet pipe away from the air pump is fixedly connected to the annular air distribution plate.

[0019] By adopting the above technical solution, the air outlet pipe is used to transport the clean gas discharged by the air pump to the annular air distribution plate. The annular air distribution plate and several evenly distributed air holes on it can make the clean gas blow upward from several air holes. In turn, the airflow can drive the dust and impurities to flow upward and spread evenly in the Chinese medicine counting cylinder. This can further ensure that the dust and impurities do not accumulate on the infrared counter, thus ensuring the accurate and efficient counting of the infrared counter and further improving the comprehensiveness of dust removal.

[0020] Optionally, the top of the dust collection box is provided with a material replacement hole located between the dust filter and the air pump. A sealing cover is fixedly installed on the top of the dust collection box by screws, and the sealing cover is adapted to the material replacement hole.

[0021] By adopting the above technical solution, the design of the material replacement hole facilitates the replacement of activated carbon particles, and the sealing cover plate is used to seal the material replacement hole.

[0022] Optionally, a cleaning hole is provided on the front side wall of the dust collection box, located between the dust filter and the Chinese medicine counting cylinder. A second sealing cover is fixedly installed on the outer side wall of the dust collection box by screws, and the second sealing cover is adapted to the cleaning hole.

[0023] By adopting the above technical solution, the design of the cleaning hole facilitates the removal of dust and impurities from the dust collection box, and the sealing cover plate is used to seal the cleaning hole.

[0024] This application includes at least one of the following beneficial technical effects:

[0025] This application utilizes a dust removal component to comprehensively and effectively remove dust and impurities mixed in with Chinese medicine granules during the counting process, achieving a highly efficient dust removal effect and improving the quality of the medicine.

[0026] This application utilizes an annular baffle to block the particles of traditional Chinese medicine, while ensuring that the dust and impurities mixed with the particles can pass smoothly through the mesh of the annular baffle, thus ensuring smooth dust removal operations.

[0027] This application sets an isolation ring seat between the annular baffle and the infrared counter. Its trapezoidal longitudinal section not only helps guide the Chinese medicine granules to fall, but also plays an isolation role, which can prevent dust and impurities from affecting the counting accuracy of the infrared counter.

[0028] This application utilizes the synergistic effect of the air outlet pipe, the annular air distribution plate, and several air holes on the annular air distribution plate. By using the airflow blown out from the air holes, dust and impurities can be driven upward and evenly diffused inside the Chinese medicine counting container. This further prevents dust and impurities from accumulating on the infrared counter, further ensures the accurate and efficient counting of the infrared counter, and further improves the comprehensiveness of dust removal.

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a dust removal mechanism for an automatic Chinese medicine counting machine, including a Chinese medicine counting and filling cylinder 1 fixedly mounted on the automatic Chinese medicine counting machine and a dust removal component disposed on the Chinese medicine counting and filling cylinder 1. A medicine inlet pipe 2 is fixedly installed at the top of the Chinese medicine counting and filling cylinder 1. The top end of the medicine inlet pipe 2 is connected to a Chinese medicine granule conveying component disposed on the automatic Chinese medicine counting machine, thereby controlling the Chinese medicine granules to fall one by one into the Chinese medicine counting and filling cylinder 1 through the medicine inlet pipe 2. This conveying component is a mature technology. A canister is fixedly installed at the bottom of the Chinese medicine counting and filling cylinder 1. An infrared counter 6 is fixedly installed on the inner wall of the medicine counting can 1, which is a medicine dispensing tube 3. The infrared counter 6 is used to count the Chinese medicine particles passing through the Chinese medicine counting can 1, providing a quantitative basis for the Chinese medicine canning. It can accurately count the number of Chinese medicine particles and ensure the accuracy of the canned Chinese medicine quantity. It should be noted that the infrared counter 6 includes a transmitter and a receiver. The structure and working principle of the infrared counter 6 are mature technologies in this field and will not be described in detail here.

[0039] The dust removal assembly includes a dust collection box 4, an air pump 5, an air extraction pipe 9, an L-shaped suction pipe 11, a ring-shaped suction pipe 12, a first suction head 13, a second suction head 14, a third suction head 15, a dust filter 7, and activated carbon granules 8. The dust collection box 4 is fixedly installed on the outer wall of the Chinese medicine counting container 1. The air pump 5 is fixedly installed on the outer wall of the dust collection box 4 away from the Chinese medicine counting container 1. One end of the air extraction pipe 9 is fixedly connected to the suction end of the air pump 5, and the other end of the air extraction pipe 9 extends into the dust collection box 4. The L-shaped suction pipe 11 is fixedly installed on the top of the dust collection box 4, and one end of the L-shaped suction pipe 11 extends into the dust collection box 4. The ring-shaped suction pipe 12 is fixedly installed on the inner wall of the Chinese medicine counting container 1 and located above the infrared counter 6. The other end of the L-shaped suction pipe 11 is fixedly connected to the ring-shaped suction pipe 12. The first suction head 13, the second suction head 14, and the third suction head 15 are... All 5 are fixedly installed on the annular suction pipe 12. The air pump 5 is used to extract the air from the dust collection box 4, so that the dust collection box 4 generates negative pressure. This, in turn, generates negative pressure inside the L-shaped suction pipe 11, the annular suction pipe 12, the first suction head 13, the second suction head 14, and the third suction head 15. During the counting of Chinese medicine granules, the dust and impurities in the Chinese medicine granules can be sucked into the dust collection box 4 for temporary storage. The dust filter 7 is fixedly installed in the dust collection box 4. One end of the L-shaped suction pipe 11 is located on one side of the dust filter 7. The activated carbon granules 8 are stored in the dust collection box 4 and located on the other side of the dust filter 7. The dust filter 7 is used to perform preliminary filtration and purification of the air containing dust and impurities entering the dust collection box 4, intercepting and blocking larger dust and impurities. The activated carbon granules 8 are used to perform secondary adsorption and purification of the air after preliminary filtration by the dust filter 7, removing small dust and impurities.

[0040] In this embodiment, the dust filter 7 is inclined, which can effectively reduce the phenomenon of clogging of the filter holes on the dust filter 7. The end of the exhaust pipe 9 located in the dust collection box 4 is fixedly installed with a baffle 10 to prevent activated carbon particles 8 from entering the L-shaped dust suction pipe 11.

[0041] In this embodiment, the number of suction heads 13, 14, and 15 is set to be multiple and evenly distributed. Suction head 13 is inclined upward, suction head 2 is horizontal, and suction head 15 is inclined downward. This allows for the extraction of dust and impurities from various locations inside the Chinese medicine counting canister 1 from different directions, improving the comprehensiveness of dust removal.

[0042] In this embodiment, an annular baffle 16 is fixedly installed inside the Chinese medicine counting container 1. The annular dust suction pipe 12, dust suction head one 13, dust suction head two 14 and dust suction head three 15 are all located inside the annular baffle 16. The annular baffle 16 serves to block the Chinese medicine particles and ensures that the dust and impurities mixed with the Chinese medicine particles can pass smoothly through the mesh on the annular baffle 16, ensuring that the dust removal operation is carried out smoothly.

[0043] In this embodiment, an isolation ring seat 17 is fixedly installed inside the Chinese medicine counting container 1. The isolation ring seat 17 is located between the annular baffle 16 and the infrared counter 6. The longitudinal section of the isolation ring seat 17 is trapezoidal. The trapezoidal longitudinal section of the isolation ring seat 17 helps to guide the Chinese medicine particles to fall smoothly, and at the same time plays a certain role in isolation, effectively preventing dust and impurities from affecting the counting accuracy of the infrared counter 6 and ensuring the cleanliness of the working environment of the infrared counter 6.

[0044] In this embodiment, the exhaust end of the air pump 5 is fixedly connected to an air outlet pipe 18. An annular air distribution plate 19 located below the infrared counter 6 is fixedly installed inside the Chinese medicine counting cylinder 1. The top of the annular air distribution plate 19 has several evenly distributed air holes 20. The end of the air outlet pipe 18 away from the air pump 5 is fixedly connected to the annular air distribution plate 19. The air outlet pipe 18 is used to transport the clean gas discharged by the air pump 5 to the annular air distribution plate 19, so that the clean gas can be blown upward from the several air holes 20. In this way, the airflow can drive the dust and impurities to flow upward and spread evenly inside the Chinese medicine counting cylinder 1. This can further ensure that the dust and impurities do not accumulate on the infrared counter 6, thus ensuring the accurate and efficient counting of the infrared counter 6 and further improving the comprehensiveness of dust removal.

[0045] In this embodiment, the top of the dust collection box 4 is provided with a material replacement hole located between the dust filter 7 and the air pump 5. A sealing cover plate 21 is fixedly installed on the top of the dust collection box 4 by screws. The sealing cover plate 21 is adapted to the material replacement hole to facilitate the replacement of activated carbon particles 8. A cleaning hole is provided on the front side wall of the dust collection box 4 located between the dust filter 7 and the traditional Chinese medicine counting container 1. A sealing cover plate 22 is fixedly installed on the outer side wall of the dust collection box 4 by screws. The sealing cover plate 22 is adapted to the cleaning hole to facilitate the cleaning out of dust and impurities in the dust collection box 4.

[0046] In this embodiment, it should be noted that the air pump 5 and the infrared counter 6 can be purchased from the market or customized from the factory. Their wiring connection method and control method are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in this article.

[0047] Based on the above structure, the working principle of the dust removal mechanism of the automatic traditional Chinese medicine counting machine provided in this application is as follows:

[0048] As the Chinese medicine granules fall one by one from the inlet pipe 2 into the Chinese medicine counting canister 1, they will pass through the middle hole of the annular baffle 16, the middle hole of the isolation ring seat 17, and the middle hole of the annular air distribution plate 19 in sequence. The number of Chinese medicine granules can be counted by the infrared counter 6. Finally, the Chinese medicine granules are discharged from the canister outlet pipe 3 for subsequent canistering operations.

[0049] As the herbal granules gradually fall into the herbal counting cylinder 1, the vacuum pump 5 is activated to extract air from the dust collection box 4, creating a negative pressure within the dust collection box 4. This negative pressure, in turn, creates negative pressure inside the L-shaped suction pipe 11, the annular suction pipe 12, and several suction heads 13, 14, and 15. Because suction heads 13 are tilted upwards, suction heads 24 are horizontal, and suction heads 15 are tilted downwards and are evenly distributed, they can draw air from the herbal counting cylinder from different directions. 1. Dust and impurities in various locations inside the chamber are drawn into the annular suction pipe 12 and then enter the dust collection box 4 through the L-shaped suction pipe 11. The air containing dust and impurities entering the dust collection box 4 is first filtered by the inclined dust filter 7. The dust filter 7 intercepts and blocks larger dust and impurities. Then, the air passes through the dust filter 7 to the other side, where it is further adsorbed and purified by the activated carbon particles 8 stored there to remove the fine dust and impurities, thereby achieving an effective dust removal effect.

[0050] During the dust removal process, by setting an isolation ring seat 17 between the annular baffle 16 and the infrared counter 6, its trapezoidal longitudinal section not only helps guide the Chinese medicine particles to fall, but also plays an isolation role, which can prevent dust impurities from affecting the counting accuracy of the infrared counter 6.

[0051] During the dust removal process, the clean gas discharged by the air pump 5 enters the annular air distribution plate 19 through the air outlet pipe 18, and is then blown upward from several evenly distributed air holes 20 at the top of the annular air distribution plate 19. The airflow blown out from the air holes 20 can drive the dust and impurities to flow upward and diffuse evenly in the Chinese medicine counting container 1, further preventing the dust and impurities from accumulating on the infrared counter 6, further ensuring the accurate and efficient counting of the infrared counter 6, and further improving the comprehensiveness of dust removal.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
