[0002] In the production process of pharmaceutical powders, it is often necessary to mix various different components of pharmaceutical powders in precise proportions according to a set dosage, especially in the stages of prescription drug preparations, traditional Chinese medicine granules, solid dosage form premixes, and pharmaceutical intermediate formulations. Therefore, it is usually necessary to use a metering device to measure the pharmaceutical powder.

[0003] As shown in the reference case "A Powder Drug Weighing and Metering Device for Preventing Scattering" (Announcement No. CN219977546U), the scattered powder enters the inner cavity of the telescopic hose through the adsorption machine, then enters the connecting pipe through the telescopic hose, and finally falls from the bottom of the connecting pipe into the collection box, thus collecting the scattered powder and avoiding resource waste.

[0004] However, existing drug powder metering devices are still mainly single-tube metering, which cannot achieve simultaneous metering and dispensing of multiple drug powders. Moreover, after dispensing, a certain amount of drug powder often remains on the wall of the metering tube, causing dosage errors and affecting the accuracy and cleanliness of subsequent batches.

[0005] Based on this, this utility model designs a multi-channel synchronous metering powder dispensing meter to solve the above problems. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A multi-channel synchronous metering powder dispensing meter, such as Figure 1 As shown, the multi-channel synchronous metering powder dispensing metering machine of this embodiment includes a detection base 100 and multiple detection platforms 110. The multiple detection platforms 110 are all fixedly installed on the top of the detection base 100. Multiple metering tubes 200 are provided on the top of the detection base 100, and the multiple metering tubes 200 are in contact with the multiple detection platforms 110 respectively. The detection and metering mechanism 300, which is used to perform multi-channel synchronous metering of powder dispensing, is provided on one side of the detection platform 110. The detection and metering mechanism 300 includes a guide frame 310 provided on the outside of the multiple metering tubes 200. A cleaning component 320 is provided on the top of the guide frame 310, and a feeding component 330 is provided on the outside of the guide frame 310.

[0032] In this embodiment of the utility model, multiple metering tubes 200 cooperate with multiple detection stations 110 during use to perform parallel and synchronous metering operations on different drug powders, realizing multi-channel synchronous dispensing. The cleaning component 320 is located on the top of the guide frame 310 and can simultaneously clean the inner walls of multiple metering tubes 200 after metering, effectively reducing drug powder residue, reducing dosage error, avoiding cross-contamination between different batches, and helping to improve the metering accuracy and cleanliness of the whole machine. The feeding component 330 is located on the outside of the guide frame 310 and can simultaneously feed the drug powder in multiple metering tubes 200 after metering. With the multi-channel structure, the tedious step of feeding one by one is eliminated, improving the overall feeding efficiency.

[0033] It should be noted that existing powder metering machines typically include basic components such as a weighing platform, a metering tube 200, a control module, and a material discharge channel. The cleaning component 320 is located on top of the guide frame 310, without interfering with the metering chamber structure and internal material channel of the metering tube 200, and without changing the signal transmission and feedback logic between the original weighing platform and the control module. At the same time, the material discharge component 330 is located on the outside of the guide frame 310, without changing the flow path and discharge method of the powder. Therefore, the setting of the cleaning component 320 and the material discharge component 330 will not affect the normal operation of the existing powder metering machine.

[0034] It should be noted that the detection station 110 is used to receive the powdered dispensing agent from inside the metering tube 200 and to complete the real-time detection and feedback of the powder quality. It is equipped with a weighing module, a support platform and signal transmission components. The weighing module may include a high-precision weighing sensor. The support platform is used to support the bottom of the metering tube 200. During the falling of the powder, the weighing sensor can sense the weight change of the powder and transmit the data to the control system in real time to display the measured weight.

[0035] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the cleaning component 320 includes a fixed frame 120 fixedly installed on the top of the detection seat 100. A movable plate 321 is slidably installed inside the fixed frame 120. The movable plate 321 is located on the top of multiple metering tubes 200. Multiple drive rods 323 are provided at the bottom of the movable plate 321, and cleaning brushes 325 are fixedly installed on the outer side of each of the multiple drive rods 323.

[0036] In this embodiment of the utility model, multiple drive rods 323 can drive the cleaning brush 325 to rotate. Correspondingly, the movable plate 321 slides downward along the fixed frame 120, driving the cleaning brush 325 to brush the inner wall of the metering tube 200 from top to bottom, thereby achieving rapid removal of residual powder inside the multiple metering tubes 200 and effectively reducing powder deposition and dosage interference.

[0037] Multiple rotating motors 322 are fixedly installed at the bottom of the movable plate 321, and the output ends of the multiple rotating motors 322 are respectively fixedly connected to multiple drive rods 323.

[0038] In this embodiment of the utility model, multiple rotating motors 322 can drive multiple driving rods 323 to rotate synchronously, thereby driving the cleaning brushes 325 on their outer sides to perform efficient rotational cleaning operations around their respective axes. This enables the rotating brushing of the inner walls of multiple metering tubes 200 to be completed simultaneously during the downward movement of the movable plate 321, thereby improving the cleaning power and coverage uniformity.

[0039] The other end of the drive rod 323 is fixedly connected to a cleaning head 326, which is set in a semi-circular shape.

[0040] In this embodiment of the utility model, the cleaning head 326 is set in a semi-circular shape, which can be used to wipe and clean the inner wall surface of the metering tube 200 during the rotation of the drive rod 323. It is especially suitable for cleaning the inner cavity of the cylindrical structure of the metering tube 200. Since the cleaning head 326 adopts a semi-circular design, it can better fit the curved surface of the tube wall, improving the cleaning coverage area and contact uniformity.

[0041] The same electric slide rail 324 is fixedly installed between the fixed frame 120 and the detection seat 100, and one side of the movable plate 321 is fixedly connected to the output end of the electric slide rail 324.

[0042] In this embodiment of the utility model, the movable plate 321 can be precisely raised and lowered in the vertical direction by driving the electric slide rail 324, thereby driving multiple drive rods 323 to rise or fall synchronously with the cleaning head 326.

[0043] Multiple cleaning brushes 325 are arranged in a ring around the outside of the drive rod 323, and multiple grooves are formed on the surface of each cleaning brush 325.

[0044] In this embodiment of the invention, multiple grooves are provided on the surface of multiple cleaning brushes 325. The groove structure helps to enhance the surface friction and powder adhesion of the brush bristles, and can more effectively scrape away the fine dust and residual particles attached to the inner wall of the metering tube 200 during the brushing process, thereby improving cleaning efficiency and residual powder removal rate.

[0045] The top edge of the testing table 110 is rounded, and the top of the testing table 110 is rounded.

[0046] In this embodiment of the utility model, the top of the testing platform 110 is a concave top surface structure. This concave design can significantly increase the contact area between the bottom of the measuring tube 200 and the testing platform 110, thereby achieving more stable support and force distribution, and improving the reliability and data accuracy of the weighing process.

[0047] In some embodiments, such as Figure 2 and Figure 5 As shown, in a preferred embodiment of the present invention, the unloading assembly 330 includes connecting plates 331 disposed on both sides of the guide frame 310. The two connecting plates 331 are slidably connected to the fixed frame 120 and the electric slide rail 324 respectively, and the guide frame 310 and the two connecting plates 331 are rotatably connected.

[0048] In this embodiment of the utility model, after completing a single dispensing measurement, the receiving container, such as the matching powder receiving box and reagent receiving box, can be placed in advance in the corresponding tilting area on one side of the detection platform 110. Then, the drive guide frame 310 rotates synchronously inside the connecting plate 331, causing multiple metering tubes 200 to rotate around their own axis. During the multi-channel feeding process, the powder can stably slide down under the action of gravity and directly enter the corresponding receiving container, achieving fast, efficient and uniform material collection.

[0049] It should be noted that this type of externally set independent receiving box structure is a standard receiving method in the powder batching and metering industry. It can be flexibly matched with containers of appropriate size and material, such as plastic boxes, stainless steel trays or special weighing tanks, according to different process links. It does not need to be connected to the main structure, which is convenient for replacement and processing in the next process. It is compatible with a variety of receiving containers and has good versatility and on-site adaptability.

[0050] Movable frames 332 are fixedly installed on the opposite sides of the two connecting plates 331. The two movable frames 332 are respectively fitted onto the outside of the electric slide rail 324 and the fixed bracket 120. The movable frames 332 are U-shaped.

[0051] In this embodiment of the utility model, the U-shaped movable frame 332 can be fitted and covered on the outside of the electric slide rail 324 and the fixed frame 120 to prevent shaking or loosening during operation.

[0052] A positioning rod 333 is provided on the surface of the movable frame 332 located outside the electric slide rail 324. The positioning rod 333 passes through the movable frame 332 and is threadedly connected to the movable frame 332.

[0053] In this embodiment of the utility model, the positioning of the guide frame 310 is released by rotating the positioning rod 333, allowing the guide frame 310 to fall freely, which facilitates multiple testing stations 110 to measure multiple measuring tubes 200. By rotating the positioning rod 333, its end is pressed against the surface of the electric slide rail 324, thereby limiting and fixing the height position of the guide frame 310 in the vertical direction.

[0054] In this embodiment of the invention, powdered preparations are poured from above into the interior of multiple metering tubes 200. Different powders of different components enter their corresponding channels and are placed in each metering tube 200 for measurement. The bottom of each metering tube 200 is in contact with the detection platform 110. During the process of the powder entering the metering tube 200, its weight is detected in real time by the weighing module inside the detection platform 110 and fed back to the control system, thereby achieving precise weighing control of the powder in each channel. When the measurement reaches the set value, the feeding component 330, in conjunction with the rotation of the guide frame 310, enables the multiple metering tubes 200 to feed synchronously, completing the multi-channel dispensing process. After the dispensing is completed, the electric slide rail 324 drives the movable plate 321 to move down, and multiple rotating motors 322 drive the drive rod 323 to rotate, thereby driving the external cleaning brush 325 and cleaning head 326 to synchronously rotate and clean the inner wall of the metering tube 200, quickly removing residual powder and avoiding cross-contamination.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
