[0020] Another objective of this invention is to provide a Chinese medicine packaging machine that can reduce manpower input and ensure the operating efficiency of the Chinese medicine packaging machine.

[0021] To achieve this objective, the present invention adopts the following technical solution:

[0022] A traditional Chinese medicine packaging machine is provided, including a packaging unit and the aforementioned filtration and cleaning device. The other end of the medicine liquid output pipe is connected to the packaging unit, which is used to package the medicine liquid into bags.

[0023] The beneficial effects of this utility model are:

[0024] This utility model provides a filtration and cleaning device, including a filter cylinder, a filter screen, a first multi-way valve, and a second multi-way valve. The filter screen is a tubular structure and is disposed inside the filter cylinder, dividing the space within the filter cylinder into a first receiving cavity between the filter screen and the filter cylinder, and a second receiving cavity within the filter screen. The filter cylinder wall has a first opening and a second opening, the first opening connecting to the first receiving cavity, and the second opening connecting to the second receiving cavity. The three valve ports of the first multi-way valve are respectively connected to the first opening, a medicine injection pipe, and a medicine residue discharge pipe. The three valve ports of the second multi-way valve are respectively connected to the second opening, a medicine output pipe, and a cleaning liquid injection pipe. When the first and second multi-way valves are configured such that the first opening is connected to the medicine injection pipe and the second opening is connected to the medicine output pipe, the medicine can enter the first receiving cavity through the medicine injection pipe and the first opening, while the medicine residue remains in the first receiving cavity. The medicine then passes through the filter screen into the second receiving cavity, and then through the second opening and the medicine output pipe, resulting in a pure, residue-free medicine solution. The first port is connected to the dregs discharge pipe, and the second port is connected to the cleaning liquid injection pipe. That is, after the medicine filtration is complete, when the filter screen needs to be cleaned and dregs removed, the cleaning liquid enters the second receiving chamber through the cleaning liquid injection pipe and the second port. As the cleaning liquid passes through the filter screen, it washes away the dregs on the outside of the filter screen and carries them through the first receiving chamber and the first port into the dregs discharge pipe, thus removing the dregs and achieving reverse cleaning of the filter screen. This filtration and cleaning device can achieve automatic cleaning, reducing labor input, avoiding time-consuming manual operation, and ensuring the operating efficiency of the Chinese medicine packaging machine.

[0025] This utility model also provides a traditional Chinese medicine packaging machine, including a packaging unit and the aforementioned filtration and cleaning device. The other end of the liquid medicine output pipe is connected to the packaging unit, which is used to package the liquid medicine into bags. This traditional Chinese medicine packaging machine can reduce labor input and ensure the operating efficiency of the machine. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] Current Chinese medicine packaging machines typically include a filter at the filling port to remove dregs from the medicinal liquid, ensuring the pure liquid is packaged. After each prescription is completed, staff need to remove and replace the filter with a new one, and also clean the replaced filter for reuse. Manually replacing and cleaning the filter is not only labor-intensive but also unsuitable for automated Chinese medicine decoction equipment, resulting in significantly reduced operating efficiency.

[0036] Therefore, this embodiment provides a filtration and cleaning device to solve the above problems. This filtration and cleaning device can reduce manpower input and ensure the operating efficiency of the Chinese medicine packaging machine.

[0037] like Figures 1-3As shown, the filtration and cleaning device of this embodiment includes a filter cylinder 1, a filter screen 2, a first multi-way valve 3, and a second multi-way valve 4. The filter screen 2 has a tubular structure and is disposed inside the filter cylinder 1, dividing the space within the filter cylinder 1 into a first receiving cavity 101 between the filter screen 2 and the filter cylinder 1, and a second receiving cavity 102 within the filter screen 2. The filter cylinder 1 has a first port 103 and a second port 104 on its wall. The first port 103 connects to the first receiving cavity 101, and the second port 104 connects to the second receiving cavity 102. The three ports of the first multi-way valve 3 are respectively connected to the first port 103, the medicine injection pipe, and the medicine residue discharge pipe. The three ports of the second multi-way valve 4 are respectively connected to the second port 104, the medicine output pipe, and the cleaning liquid injection pipe. When the first multi-way valve 3 and the second multi-way valve 4 are configured such that the first port 103 is connected to the liquid injection pipe and the second port 104 is connected to the liquid output pipe, the liquid can enter the first receiving chamber 101 through the liquid injection pipe and the first port 103, while the residue remains in the first receiving chamber 101. The liquid then enters the second receiving chamber 102 through the filter screen 2, and then through the second port 104 and the liquid output pipe to obtain a pure, residue-free liquid. When the first port 103 is connected to the residue discharge pipe and the second port 104 is connected to the cleaning liquid injection pipe, that is, when the liquid is filtered and the filter screen 2 needs to be cleaned to remove residue, the cleaning liquid can enter the second receiving chamber 102 through the cleaning liquid injection pipe and the second port 104. During the process of the cleaning liquid passing through the filter screen 2, it will backwash away the residue on the outside of the filter screen 2 and carry the residue through the first receiving chamber 101 and the first port 103 into the residue discharge pipe, thereby removing the residue and achieving reverse cleaning of the filter screen 2. This filtration and cleaning device can achieve automatic cleaning, which reduces labor input, avoids time-consuming manual operation, and ensures the operating efficiency of the Chinese medicine packaging machine.

[0038] Optionally, the axial direction of the filter cylinder 1 is parallel to the axial direction of the filter screen 2, and the first opening 103 is formed on the side wall of the filter cylinder 1. Optionally, the filter cylinder 1 and the filter screen 2 are coaxially arranged so that the gap between the filter cylinder 1 and the filter screen 2 is consistent throughout the circumference.

[0039] Optionally, the filter screen 2 is circumferentially connected to the inner wall of the filter cylinder 1 along one end edge of its own axis, and the second opening 104 is opened at the cylinder wall of the filter cylinder 1 surrounded by the filter screen 2 along one end edge of its own axis, so that the medicine liquid must be filtered through the filter screen 2 before reaching the second opening 104, preventing some medicine residue from remaining in the medicine liquid.

[0040] Optionally, the filter cylinder 1 is axially vertical, and the second port 104 is opened on the bottom wall of the filter cylinder 1 to facilitate the output of the medicine.

[0041] Optionally, in some embodiments, the inner side of the bottom wall of the filter cylinder 1 is horizontally arranged. In other embodiments, the inner side of the bottom wall of the filter cylinder 1 is inclined, and the height of the inner side of the bottom wall of the filter cylinder 1 decreases as it approaches the axial direction of the filter cylinder 1, so that the liquid can flow to the second inlet 104 and no liquid remains on the bottom wall.

[0042] Optionally, the inner diameter of the second port 104 increases as it approaches the second receiving cavity 102 along its own longitudinal direction. That is, the inner diameter of the second port 104 decreases as it flows in the direction of the liquid flow. This ensures that the opening size of the second port 104 at the bottom wall of the filter cylinder 1 is relatively large. On the one hand, this facilitates the output of the liquid. On the other hand, when the cleaning liquid is used for reverse cleaning, the side wall of the second port 104 can guide the cleaning liquid to the filter screen 2, thereby improving the cleaning efficiency and cleaning power.

[0043] Optionally, the filter cartridge 1 is vertical in direction. The filter cartridge 1 includes a body 11 and a top cover 12. The top cover 12 is detachably placed on the upper opening of the body 11 to facilitate opening the top cover 12 for cleaning the filter cartridge 1. The filter screen 2 is easy to replace after multiple uses.

[0044] Optionally, the filter screen 2 is made of stainless steel or nylon. Optionally, food-grade stainless steel or medical-grade nylon mesh can be used. In addition, from the perspective of textile technology, non-woven fabric weaving technology can be used.

[0045] Optionally, the mesh size of filter screen 2 is 80-160 mesh. If the mesh size of filter screen 2 is too small, it will not be conducive to improving the filtration efficiency of the medicine liquid. If the mesh size of filter screen 2 is too large, it will not be conducive to intercepting all the medicine residue, and a large amount of medicine residue will still remain in the medicine liquid.

[0046] Optionally, the cross-sections of both the filter cylinder 1 and the filter screen 2 are circular, elliptical, or polygonal. In this embodiment, the cross-sections of both the filter cylinder 1 and the filter screen 2 are circular.

[0047] Optionally, in this embodiment, both the first multi-way valve 3 and the second multi-way valve 4 are three-way valves.

[0048] Optionally, a liquid pump is provided on the liquid injection pipe to provide the power for the flow of the liquid.

[0049] Optionally, the cleaning fluid is clean water with a certain pressure, or hot water with a high temperature, or clean water with both a certain pressure and a high temperature, to ensure the impact force and cleaning ability of the cleaning fluid on the drug residue on the outside of the filter screen 2.

[0050] Optionally, the filter cartridge 1 and filter screen 2 are designed to filter 1-14 doses of traditional Chinese medicine.

[0051] Optionally, to ensure synchronous adjustment between the first multi-way valve 3 and the second multi-way valve 4, both the first multi-way valve 3 and the second multi-way valve 4 are electronic three-way valves. The filtration and cleaning device also includes a controller, which is communicatively connected to both the first multi-way valve 3 and the second multi-way valve 4. The controller can control the synchronous adjustment of the first multi-way valve 3 and the second multi-way valve 4 so that when the first port 103 is connected to the drug injection pipe, the second port 104 is connected to the drug output pipe; when the first port 103 is connected to the drug residue discharge pipe, the second port 104 is connected to the cleaning liquid injection pipe. The entire filtration and cleaning process is automated, completely avoiding medical accidents caused by human error in failing to replace the filter screen 2 in a timely manner, greatly improving safety.

[0052] Optionally, the controller is a conventional programmable logic controller, and can be selected from Siemens S7-1200 / 1500 series, Mitsubishi Q series or Omron CP / CP1H series as needed.

[0053] Optionally, in other embodiments, both the first multi-way valve 3 and the second multi-way valve 4 are mechanical three-way valves. The first multi-way valve 3 and the second multi-way valve 4 are manually adjusted synchronously to ensure that when the first port 103 is connected to the drug injection pipe, the second port 104 is connected to the drug output pipe; and when the first port 103 is connected to the drug residue discharge pipe, the second port 104 is connected to the cleaning liquid injection pipe. Even if both the first multi-way valve 3 and the second multi-way valve 4 are mechanical three-way valves requiring manual adjustment, the manual operation steps are extremely simple and convenient. When the operator needs to perform other tasks, the switching between forward filtration and reverse cleaning can be quickly completed, still helping to avoid the risk of drug mixing caused by filtering the next prescription before the filter screen 2 is cleaned, thus improving safety.

[0054] This filtration and cleaning device can automatically filter medicinal residue and automatically clean the filter screen 2. The whole process does not require a lot of manual labor, meets the high-efficiency operation requirements of modern Chinese medicine decoction production lines, and helps to improve safety.

[0055] This embodiment also provides a traditional Chinese medicine packaging machine, including a packaging unit and the above-mentioned filtration and cleaning device. The other end of the medicine liquid output pipe is connected to the packaging unit, which is used to package the medicine liquid into bags, that is, the filtered medicine liquid can be packaged.

[0056] By incorporating the aforementioned filtration and cleaning device, this Chinese medicine packaging machine can effectively reduce labor input, improve operating efficiency, help avoid medical accidents caused by mixed medicines, and enhance safety.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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 here.
