High-efficiency traditional Chinese medicine decoction piece screening device

Abstract

This utility model relates to the field of screening device technology, and specifically discloses a high-efficiency screening device for Chinese herbal medicine slices. It includes a feeding cylinder with a filter screen inside for preliminary filtration of the herbal medicine slices. A collection mechanism includes an opening and a collection box. A pusher plate is slidably connected to the inner side of the collection rack. When the herbal medicine slices are poured into the feeding cylinder, they first come into contact with the filter screen. The filter screen blocks larger particles from the herbal medicine slices. When too many herbal medicine slices accumulate on the surface of the filter screen, the pusher plate moves to push the herbal medicine slices on the filter screen surface, allowing them to pass through the opening and enter the collection box. Therefore, the filter screen, in conjunction with the collection mechanism, separates large foreign objects from the herbal medicine slices in advance, preventing them from entering subsequent screening stages and interfering with the normal screening process. This ensures that qualified herbal medicine slices are screened out, reducing the probability of secondary screening and thus guaranteeing screening efficiency.

Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a high-efficiency screening device for traditional Chinese medicine decoction pieces. Background Technology

[0002] High-efficiency Chinese herbal medicine (TCM) decoction piece screening devices are professional equipment used in the processing of TCM decoction pieces. They aim to quickly and accurately separate TCM decoction pieces of different specifications while effectively removing impurities, thereby improving the production efficiency and quality of TCM decoction pieces. One type of device is the linear vibrating screen, which has the following structure:

[0003] 1. Screen: This is the component that directly performs the screening operation. The size of the screen aperture determines the range of particle size that can be screened. Different screen apertures can be selected according to specific screening requirements.

[0004] 2. Feed cylinder: Chinese medicinal herbs enter the screen through the feed cylinder.

[0005] 3. Vibrating motor: It is the power source of the linear vibrating screen. It generates excitation force through high-speed rotation, causing the screen box to reciprocate linearly.

[0006] During the production of Chinese herbal medicine slices, due to the wide range of sources and diverse types of raw medicinal materials, large foreign objects are easily mixed in during harvesting, transportation, and storage. Chinese herbal medicine slices are usually relatively regular in shape and small and uniform in size, and can move relatively smoothly on the sieve surface. However, large foreign objects are irregular in shape and may have sharp edges or protrusions, making their contact with the sieve surface complex.

[0007] Therefore, the movement of large foreign objects on the sieve surface is different from that of Chinese medicinal herbs, thus interfering with the normal sieving of Chinese medicinal herbs. This causes some qualified herbs that should have passed through the sieve to be blocked or carried out by large foreign objects, resulting in qualified Chinese medicinal herbs not being screened out and needing to be screened again, which in turn affects the screening efficiency. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a high-efficiency traditional Chinese medicine (TCM) decoction piece screening device. It solves the technical problem that large foreign objects move differently on the sieve surface than TCM decoction pieces, thus interfering with the normal screening of TCM decoction pieces. This causes some qualified decoction pieces that should pass through the sieve to be blocked or carried out by large foreign objects, resulting in qualified TCM decoction pieces not being screened out and requiring re-screening, which in turn affects the screening efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-efficiency traditional Chinese medicine (TCM) decoction piece screening device includes a feeding cylinder. The inside of the feeding cylinder is equipped with a filter screen for preliminary filtration of TCM decoction pieces. At one end of the feeding cylinder corresponding to the filter screen, a collection mechanism for collecting TCM decoction pieces is provided. The collection mechanism includes an opening and a collection box. The opening is located outside the feeding cylinder, and the collection box is fixedly installed on one side of the feeding cylinder corresponding to the opening. At the end of the feeding cylinder away from the collection box, a pusher is provided for stacking TCM decoction pieces. A storage rack is fixedly installed outside the feeding cylinder, and the pusher is slidably connected to the inside of the storage rack.

[0011] Preferably, the feed cylinder is provided with a limiting mechanism for fixing the filter screen at both ends. The limiting mechanism includes a limiting plate, an opening and a fixing plate. The limiting plate is fixedly installed inside the feed cylinder, the opening is opened outside the feed cylinder and communicates with the inside of the feed cylinder, and the fixing plate is slidably connected between the opening and the inside of the feed cylinder.

[0012] Preferably, a threaded rod is fixedly installed at one end of the feed cylinder corresponding to each fixed plate, the fixed plate is slidably connected to the outside of the threaded rod, and a limit rod for restricting the movement of the fixed plate is threaded to the outside of each threaded rod.

[0013] Preferably, a sealing plate for sealing the feed cylinder is slidably connected inside the opening, and an internal groove is provided inside the opening. The lower end of the sealing plate is engaged inside the internal groove. A limiting spring is provided at the lower end of the sealing plate to restrict the movement of the sealing plate. A receiving groove is provided at the lower end of the sealing plate, and one end of the limiting spring is fixedly connected inside the receiving groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the Chinese herbal medicine slices are poured into the feed cylinder, they first come into contact with the filter screen. The filter screen blocks larger pieces of the herbal medicine slices. When too many herbal medicine slices accumulate on the surface of the filter screen, a moving pusher pushes the herbal medicine slices on the surface of the filter screen so that they enter the collection box through the opening. Therefore, the filter screen, together with the collection mechanism, separates large foreign objects from the herbal medicine slices in advance, preventing them from entering the subsequent screening process and interfering with the normal screening process of the herbal medicine slices. This allows qualified herbal medicine slices to be screened out, reduces the probability of secondary screening, and thus ensures screening efficiency.

[0016] 2. Release the connection between the limit rod and the threaded rod, and then pull the fixing plate to release the connection between the fixing plate and the threaded rod. At this time, the filter screen can be pulled upward to remove the inside of the feed cylinder. The detachable design of the filter screen makes it easy to clean. At the same time, according to the screening requirements of different Chinese herbal medicine pieces, filter screens with different pore sizes can be replaced to improve the flexibility of filter screen use.

[0023] This application provides a high-efficiency traditional Chinese medicine (TCM) decoction piece screening device, which effectively solves the technical problem that large foreign objects move differently on the sieve surface than TCM decoction pieces, thus interfering with the normal screening of TCM decoction pieces. This causes some qualified decoction pieces that should pass through the sieve to be blocked or carried out by large foreign objects, resulting in qualified TCM decoction pieces not being screened out and needing to be screened again, thereby affecting the screening efficiency.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that the movement state of large foreign objects on the sieve surface is different from that of Chinese medicinal herbs, thus interfering with the normal sieving of Chinese medicinal herbs. This causes some qualified herbs that should pass through the sieve to be blocked or carried out by large foreign objects, resulting in qualified Chinese medicinal herbs not being screened out and needing to be screened again, thereby affecting the screening efficiency. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a high-efficiency traditional Chinese medicine (TCM) decoction piece screening device, including a feeding cylinder 1. The inside of the feeding cylinder 1 is provided with a filter screen 2 for preliminary filtration of TCM decoction pieces. At one end of the feeding cylinder 1 corresponding to the filter screen 2, a collection mechanism for collecting TCM decoction pieces is provided. The collection mechanism includes an opening 3 and a collection box 4. The opening 3 is opened on the outside of the feeding cylinder 1, and the collection box 4 is fixedly installed on the side of the feeding cylinder 1 corresponding to the opening 3. At the end of the feeding cylinder 1 away from the collection box 4, a pusher 5 for stacking TCM decoction pieces is provided. The pusher 5 is T-shaped. A storage rack 6 is fixedly installed on the outside of the feeding cylinder 1. The storage rack 6 is a concave body, and the pusher 5 is slidably connected to the inner side of the storage rack 6.

[0027] Both ends of the feed cylinder 1 corresponding to the filter screen 2 are provided with limiting mechanisms for fixing the filter screen 2. The limiting mechanism includes a limiting plate 7, an opening 8 and a fixing plate 9. The limiting plate 7 is fixedly installed inside the feed cylinder 1, the opening 8 is opened outside the feed cylinder 1 and communicates with the inside of the feed cylinder 1, and the fixing plate 9 is slidably connected between the opening 8 and the inside of the feed cylinder 1. The end of the filter screen 2 is located between the fixing plate 9 and the limiting plate 7.

[0028] Each feed cylinder 1 has a threaded rod 10 fixedly installed at one end of each fixed plate 9. The fixed plate 9 is slidably connected to the outside of the threaded rod 10. Each threaded rod 10 is threadedly connected to the outside of a limiting rod 11 for restricting the movement of the fixed plate 9. The limiting rod 11 is composed of a threaded sleeve and cuboid plates fixed at both ends of the threaded sleeve.

[0029] The opening 3 has a sliding connection to a sealing plate 12 for sealing the feed cylinder 1. The sealing plate 12 is T-shaped. The opening 3 has an internal groove 13. The lower end of the sealing plate 12 is engaged inside the internal groove 13. The lower end of the sealing plate 12 is provided with a limiting spring 14 for restricting the movement of the sealing plate 12. The lower end of the sealing plate 12 has a receiving groove 15. One end of the limiting spring 14 is fixedly connected inside the receiving groove 15.

[0030] Filter screen 2: Preliminary screening of medicinal slices, allowing slices of the correct size to pass through, and intercepting excessively large slices to prevent them from entering the screening device, thereby avoiding large foreign objects from getting stuck in the screen or blocking the channel;

[0031] Collection box 4: Receives oversized medicinal slices intercepted by filter screen 2 for centralized processing;

[0032] Closed plate 12 and opening 3: Adjust the connection between closed plate 12 and opening 3 to control the opening and closing of opening 3;

[0033] Pusher 5: Manually push the large-particle beverage pieces accumulated on the filter screen 2 to slide them into the collection box 4, thereby avoiding clogging of the filter screen 2 and improving continuous operation efficiency;

[0034] Storage rack 6: Stores pushers 5 to prevent loss and make them easy to access;

[0035] Limiting mechanism: The end of the filter screen 2 is located between the fixing plate 9 and the limiting plate 7. The limiting plate 7 is located on the lower surface of the filter screen 2. The connection between the fixing plate 9 and the opening 8 facilitates the quick assembly and disassembly of the filter screen 2.

[0036] Threaded rod 10 and limiting rod 11: When the fixing plate 9 is located on the upper surface of the filter screen 2, one end of the fixing plate 9 slides outside the threaded rod 10, and then the limiting rod 11 is threadedly connected to the threaded rod 10 until the limiting rod 11 is attached to the outside of the fixing plate 9, so as to prevent the fixing plate 9 from being moved away from the upper surface of the filter screen 2 during the operation of the device, thereby ensuring the stability of the filter screen 2 installation;

[0037] Built-in groove 13 and limiting spring 14: The connection between the built-in groove 13 and the sealing plate 12 can limit the lateral movement of the sealing plate 12. The limiting spring 14 is tightly attached to the inner wall of the built-in groove 13, forming a large friction force, thereby preventing the sealing plate 12 from accidentally loosening or falling out during use.

[0038] Working principle:

[0039] First, the Chinese herbal medicine slices are poured into the inside of the feeding cylinder 1. At this time, the Chinese herbal medicine slices first come into contact with the filter screen 2. The filter screen 2 blocks the larger materials in the Chinese herbal medicine slices. When too many Chinese herbal medicine slices accumulate on the surface of the filter screen 2, the sealing plate 12 is pulled upward to disconnect the connection between the sealing plate 12 and the internal groove 13 and the opening 3. Then, the push plate 5 is taken out from the inside of the mounting frame and inserted into the inside of the feeding cylinder 1 to push the Chinese herbal medicine slices on the surface of the filter screen 2 so that the Chinese herbal medicine slices enter the inside of the collection box 4 through the opening 3. Then, the sealing plate 12 is inserted into the inside of the opening 3. At this time, the lower end of the sealing plate 12 enters the inside of the internal groove 13. During this process, the limiting spring 14 moves into the inside of the receiving groove 15 and fits against the inner wall of the internal groove 13. At this time, the feeding cylinder 1 is sealed.

[0040] The second step is to rotate the limiting rod 11 to disconnect the connection between the limiting rod 11 and the threaded rod 10. At this time, pull the fixing plate 9 to disconnect the connection between the fixing plate 9 and the threaded rod 10. At this time, the fixing plate 9 is removed from the upper surface of the filter screen 2. Then, the filter screen 2 can be pulled upward to remove the inside of the feed cylinder 1. After that, the filter screen 2 can be cleaned.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
