Description

Technical Field

[0001] This application relates to a device for combining Chinese medicine pills, belonging to the technical field of Chinese medicine processing equipment. Background Technology

[0002] Currently, many traditional Chinese medicine (TCM) clinical prescriptions are being converted from decoctions to pills. However, these prescriptions often involve large doses, and if finely powdered medicinal herbs are used directly, the daily dosage becomes too high, leading to poor patient compliance. TCM pills solve this problem. Pills are made by extracting and concentrating medicinal herbs or a portion thereof, then combining them with suitable excipients or other finely powdered herbs, along with a binder. Pills require smaller doses, are easier to take and absorb, and are convenient to store and carry.

[0003] CN117654363A discloses a device for mixing traditional Chinese medicine honey pills, including a base. A support frame is fixedly connected to the top left and right ends of the base. A mounting seat is fixedly connected to the bottom of the base near a corner. An arc-shaped pressure plate has an arc-shaped hook end at its top. Ball bearings are rolled onto the side surface of the arc-shaped pressure plate. The distance between the arc-shaped pressure plate and the side surface of a spherical tank gradually decreases from bottom to top. The left end of the outer surface of the spherical tank extends into the interior of a gearbox. A servo motor is installed on the left side of the outer surface of the gearbox near the bottom. An auxiliary component is provided on the top of the spherical tank. Driven material-turning components are provided on both the left and right sides of the outer surface of the spherical tank. This device achieves uniform mixing.

[0004] However, the aforementioned herbal pill-forming device requires the addition of herbs and water before stirring. For the preparation of some pills, the raw materials need to be added in batches, so this herbal pill-forming device cannot be used. In addition, this herbal pill-forming device cannot guarantee that the ratio of herbs to water is appropriate. That is to say, the amount of herbs and water to be added can only be obtained through theoretical calculations, and the water ratio cannot be determined according to the actual situation during the stirring process. Therefore, it will be difficult to successfully make pills. Utility Model Content

[0005] To address the aforementioned issues, this application proposes a traditional Chinese medicine pill-forming device that not only enables the addition of raw materials in batches during the stirring process but also automatically adjusts the amount of water added based on the viscosity of the mixed powder, ensuring successful pill-making.

[0035] Reference Figs. 1-3 This application describes a device for combining Chinese medicine pills.

[0036] The herbal pill-forming device according to this embodiment includes a base 1 and a frame 2 disposed above the base 1. A material-holding component is disposed on the base 1, and a stirring component and a liquid-injection component are disposed on the frame 2. The liquid-injection component is located above the material-holding component, and the lower end of the stirring component extends into the material-holding component. This herbal pill-forming device has a compact structure, high integration, small footprint, and is easy to transport and install. At the same time, it has a high degree of automation and does not require much manual intervention. Under the premise of ensuring the quality and consistency of the pills, it greatly improves production efficiency.

[0037] The material holding assembly includes a mixing pot 3 and a first servo motor 4. The mixing pot 3 and the first servo motor 4 are rotatably connected, which can achieve more uniform mixing, improve the efficiency and quality of material mixing, and reduce the adhesion of materials on the inner wall of the mixing pot 3, making it easier to clean later.

[0038] The mixing assembly includes a second servo motor 5, a torque sensor 6, and a mixing paddle 7. The second servo motor 5 is housed within the frame 2, with a reasonable layout that facilitates precise control of the mixing paddle 7's rotation speed, ensuring both mixing quality and efficiency. The torque sensor 6 is connected to the output shaft of the second servo motor 5, and the mixing paddle 7 is connected to the end of the torque sensor 6 furthest from the second servo motor 5. This allows for real-time monitoring of torque changes during the mixing process, enabling timely adjustment of mixing parameters based on the degree of material mixing to ensure optimal mixing performance. The end of the mixing paddle 7 furthest from the torque sensor 6 is located within the mixing pot 3, achieving direct and effective mixing of the materials, thereby improving mixing efficiency.

[0039] The liquid injection assembly includes a liquid injection pump 8 and a liquid outlet pipe 9. One end of the liquid outlet pipe 9 is connected to the liquid injection pump 8, and the other end is located above the mixing pot 3, so as to accurately control the amount of water added at different stages and ensure the success of pelleting.

[0040] In this invention, the stirring paddle 7 is spiral-shaped, which can drive the material to form a circulating flow in the mixing pot 3, ensuring that the material in each position can be fully stirred, thereby improving the mixing efficiency and mixing effect of the material.

[0041] In particular, the movement of the stirring paddle 7 and the movement of the mixing pot 3 work together to make the material move along a planetary trajectory, avoiding dead corners in the mixing process and ensuring that the material achieves a high degree of uniformity and consistency during the mixing process, thereby helping to improve the success rate of pelleting.

[0042] In this invention, the mixing pot 3 is open, which allows for the addition of raw materials in batches during the mixing process and facilitates cleaning and maintenance of the mixing pot 3 after use.

[0043] As one implementation, a disc seat 10 is provided on the base 1. The disc seat 10 helps to enhance the connection stability between the mixing pot 3 and the base 1. A rotating shaft 11 is provided at the bottom of the mixing pot 3. The end of the rotating shaft 11 away from the mixing pot 3 passes through the disc seat 10 and extends into the base 1, so as to facilitate the connection between the mixing pot 3 and the first servo motor 4 through the rotating shaft 11, thereby realizing the smooth rotation of the mixing pot 3.

[0044] In one embodiment, a limiting ring 12 is provided at one end of the rotating shaft 11 near the mixing pot 3. The bottom surface of the limiting ring 12 is in contact with the top surface of the disc seat 10, which can limit the axial movement of the rotating shaft 11 during the mixing process, reduce the wear between the rotating shaft 11 and the disc seat 10, and thus extend the service life of the device.

[0045] As one implementation method, a limiting block 13 is provided on the disc base 10. The limiting block 13 abuts against the outer periphery of the limiting ring 12, which effectively prevents the mixing pot 3 from shifting or shaking due to uneven force or excessive vibration during operation, and ensures the smooth progress of the mixing process.

[0046] In one implementation, a first pulley 14 is provided on the output shaft of the first servo motor 4, and a second pulley 15 is provided at the end of the rotating shaft 11 away from the mixing pot 3. The first pulley 14 and the second pulley 15 are connected by a belt 16. Power is transmitted from the first servo motor 4 to the rotating shaft 11 by the first pulley 14, the second pulley 15 and the belt 16, ensuring the continuity and uniformity of the mixing process, thereby improving the mixing efficiency.

[0047] In one implementation, the first servo motor 4 is located at the connection between the frame 2 and the base 1, and the first pulley 14, the second pulley 15 and the belt 16 are all located inside the base 1. The layout is compact, which improves the space utilization rate. At the same time, it prevents dust, moisture and other pollutants from entering the device and damaging the belt 16 and other components, thus extending the service life of the device and reducing maintenance costs.

[0048] In one implementation, a liquid filling seat 17 is provided on the side of the frame 2 near the torque sensor 6, and a liquid outlet head 18 is provided on the side of the liquid filling seat 17 near the mixing pot 3. The liquid outlet pipe 9 is connected to the side of the liquid filling seat 17 away from the liquid outlet head 18, which makes full use of the internal space of the device, reduces the loss and splashing of liquid during the transmission process, and improves the efficiency and accuracy of liquid filling.

[0049] In one implementation, the end of the outlet pipe 9 away from the liquid filling base 17 is connected to the liquid injection pump 8. The liquid injection pump 8 is provided with an inlet pipe 19. The end of the inlet pipe 19 away from the liquid injection pump 8 extends to the outside of the frame 2, which facilitates connection to an external water source, thereby realizing the addition and replenishment of liquid during the mixing process.

[0050] In one implementation, a controller 20 is installed inside the frame 2. The first servo motor 4, the second servo motor 5, the torque sensor 6, and the injection pump 8 are all connected to the controller 20. The torque sensor 6 is used to acquire the torque of the stirring paddle 7 in real time and transmit it to the controller 20. The controller 20 is used to control the speed of the first servo motor 4 and the second servo motor 5, as well as the start and stop of the injection pump 8, according to the signal from the torque sensor 6.

[0051] In one implementation, an operation panel 21 is provided on the outside of the frame 2. The operation panel 21 is connected to the controller 20. The operation panel 21 is provided with control buttons 22. Control commands are issued through the control buttons 22, and the controller 20 receives the control commands to realize the control of the combining device.

[0052] Because the content of each herb in each prescription is different, the viscosity of each prescription powder is also different. In order to accurately determine whether the mixed powder is sufficiently and uniformly stirred, it is necessary to provide real-time feedback on the viscosity of the mixed powder. This utility model uses real-time feedback torque as a substitute for real-time viscosity testing. "Torque" is used as the measured physical quantity. The measured torque is used as a signal to control the speed change of the first servo motor 4 and the second servo motor 5, as well as the amount of water added by the injection pump 8.

[0053] When the torque detected by the torque sensor 6 changes, the torque sensor 6 sends a signal to the controller 20. The controller 20 immediately sends an instruction to the first servo motor 4 and the second servo motor 5 to increase or decrease the speed of the first servo motor 4 and the second servo motor 5. According to the real-time torque received by the controller 20, the injection pump 8 is controlled to run for a certain period of time to add a certain amount of water to increase the viscosity of the mixed powder. When the viscosity reaches the specified range, the injection pump 8 is then controlled to shut down.

[0054] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0055] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
