Technical Field

[0001] This utility model belongs to the technical field of pill production equipment, specifically a raw material weighing device for pill preparation. Background Technology

[0002] In the production and preparation of pills, accurate weighing of raw materials is a crucial step in ensuring pill quality. Taking Huanglian Qingwei Pills as an example, the raw materials of this common traditional Chinese medicine include a variety of Chinese medicinal herbs such as Coptis chinensis, Gardenia jasminoides, Forsythia suspensa, and Rheum palmatum, and most of them are in powder form.

[0003] These powdery raw materials tend to adhere to the inner wall of the weighing device during weighing, causing a deviation between the actual amount of raw materials used in preparation and the preset formula ratio, thus affecting the quality of the pills. Furthermore, the adhered raw materials are difficult to clean, often requiring operators to manually remove them with a brush. This process is not only cumbersome and ineffective, but also inconvenient for material handling, significantly reducing production efficiency. Utility Model Content

[0015] 3. Simple and efficient operation: The overall structure of this device is reasonably designed. During the weighing process, the operator only needs to pour the raw materials into the conical chamber. After the weight reaches the preset value, the operator can complete the raw material transportation by simply opening the valve and starting the motor. No complicated manual intervention is required. At the same time, the weighing and transportation processes are seamlessly connected, reducing the time consumption of intermediate links and improving the work efficiency of the raw material weighing link in pill preparation.

[0016] 4. Enhanced automation: This device uses motor one to drive the scraping mechanism and motor two to drive the conveying mechanism, thus automating the scraping and conveying of raw materials. This reduces the intensity of manual labor, minimizes errors and risks caused by improper manual operation, and makes the production process more stable and controllable.

[0017] 5. Facilitates raw material transfer and subsequent processing: After the weighed raw materials are discharged through the conveying pipe, they can be easily collected into other containers. The entire process is smooth, reducing spillage and pollution during raw material transfer and ensuring a clean production environment.

[0018] In summary, this utility model, through its scientific structural design, excels in improving weighing accuracy, increasing raw material utilization, simplifying operation procedures, enhancing automation, and facilitating raw material transfer and processing. It effectively meets the stringent requirements for raw material weighing during pill preparation and has high practical value and promotional significance. Attached Figure Description

[0027] The arc-shaped slider 7 is slidably connected to the annular groove 5 and fixedly connected to the connecting plate 8. One end of the connecting plate 8 is fixedly connected to the shovel plate 9. The shovel plate 9 is slidably fitted against the inner wall of the conical chamber 4. The other end of the connecting plate 8 is fixedly connected to the motor 10. The output shaft of the motor 10 is fixedly connected to the spur gear 11. The spur gear 11 is meshed with the external gear ring 6.

[0028] The conveying mechanism includes an auger 15, a second motor 16, and a fixing plate 17;

[0029] The auger 15 is horizontally arranged inside the feed pipe 14. One end of the auger 15 is fixedly connected to the output shaft of the second motor 16.

[0030] The spiral blades of the auger 15 are made of silicone, and the outer wall of the spiral blades is slidably fitted against the inner wall of the feed pipe 14.

[0031] This utility model of a raw material weighing device for pill preparation achieves accurate weighing and efficient transport of pill raw materials through the coordinated operation of multiple components. Its detailed working principle is as follows:

[0032] Before starting the device, the weighing device 1 is zeroed (weighing device 1 is existing technology, preferably an electronic weighbridge) to ensure that the initial weighing state is accurate. Then, the operator pours the raw materials required for pill preparation into the conical chamber 4 through the opening at the top. When not in use, the opening at the top of the conical chamber 4 can be closed with a dust cover. When in use, the dust cover is opened. At this time, the weighing device 1 will monitor and display the cumulative weight of the poured raw materials in real time. When the displayed weight reaches the preset value required for production, the addition of raw materials into the conical chamber 4 is stopped, and the initial weighing of the raw materials is completed.

[0033] After the raw materials are weighed, open the valve 13 (preferably a ball valve, etc.) on the connecting pipe 12 so that the raw materials in the conical hopper 4 can enter the conveying pipe 14 through the connecting pipe 12. At the same time, start the motor 10 and motor 2 16 through the external power supply to start the raw material conveying process.

[0034] During the transfer of raw materials from the conical silo 4 to the conveying pipe 14, the scraping mechanism operates synchronously to prevent raw material residue. The motor 10 drives the spur gear 11 to rotate. Since the spur gear 11 meshes with the external gear ring 6 fixed on the conical silo 4, and the arc-shaped slider 7 slides within the ring groove 5, the connecting plate 8 drives the scraper 9 to make a circular motion along the inner wall of the conical silo 4. The scraper 9 fits tightly against the inner wall of the conical silo 4. The scraper 9 is preferably made of silicone, which can completely scrape off the raw materials adhering to the silo wall, ensuring that all weighed raw materials can smoothly enter the conveying pipe 14, effectively improving the utilization rate of raw materials and the accuracy of weighing.

[0035] The raw materials entering the conveying pipe 14 are smoothly transported to the target position under the action of the conveying mechanism. The motor 16 drives the auger 15 to rotate inside the conveying pipe 14. The silicone spiral blades of the auger 15 are tightly attached to the inner wall of the conveying pipe 14. During the rotation, it can not only push the raw materials evenly, but also clean the inner wall of the conveying pipe 14 to avoid raw material residue. The raw materials are finally discharged through the outlet of the conveying pipe 14, or they can directly enter the subsequent container or pelletizing device, realizing a seamless connection between weighing and conveying.

[0036] Once the raw material is conveyed, close valve 13 and shut down motor 10 and motor 2 16 to complete a complete raw material weighing and conveying process. The entire device is easy to operate and highly automated, which can effectively improve the efficiency and accuracy of raw material weighing during pill preparation.

Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention.
