[0002] In the pharmaceutical production process, packaging is an essential step. For example, powdered medicine is typically packaged into bottles using a packaging machine. Due to the physical properties of the powder, during the packaging process, factors such as airflow and vibration may cause some powder to remain outside the bottle, potentially leading to contamination and affecting the purity and safety of the powder.

[0003] In existing technologies, dust collection systems are generally used to remove powder. These systems typically position the suction nozzle close to the dispensing area to remove powder outside the medicine bottle; therefore, the nozzle's structure directly impacts the suction efficiency. For example, Chinese patent CN202323198791.7 uses a suction ring between the discharge port and the receiving container to create a ring-shaped negative pressure for dust capture. However, in existing technologies, the airflow at the nozzle inlet is diffused and difficult to focus, resulting in low suction efficiency and potentially negatively impacting the cleanliness, purity, and safety of the dispensed powder.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] It should also be noted that the division of multiple embodiments in this utility model is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction. See the accompanying drawings.

[0032] During the packaging process of medicines, due to the physical properties of the medicines themselves, they are easily affected by factors such as airflow and vibration, and medicines (such as pills, powders, etc.) are prone to producing powder (including powder and debris generated by friction). The powder may not enter the medicine bottle but remain outside the bottle, which may cause contamination and affect the purity and safety of the powder.

[0033] In existing technologies, a vacuum system is generally used to remove powder. This vacuum system typically positions the nozzle close to the dispensing area to remove powder outside the medicine bottle; therefore, the nozzle's structure directly affects the vacuuming efficiency. However, in existing vacuum nozzles, the airflow at the inlet is diffused and difficult to focus, resulting in low vacuuming efficiency and potentially negatively impacting the cleanliness, purity, and safety of the dispensed powder.

[0034] Based on this, see Figures 1 to 8 This utility model provides a powder filling device 1, including a conveying component 10, a powder filling component 20, and a powder suction component 30. The conveying component 10 includes a conveyor belt 11. The conveyor belt 11 can carry dispensing bottles 40 for conveying the dispensing bottles 40.

[0035] The powder filling assembly 20 has a powder outlet 21, which is located above the conveyor belt 11. It is understood that the space between the powder outlet 21 and the conveyor belt 11 is sufficient to accommodate the dispensing bottles 40.

[0036] The powder suction assembly 30 includes a base 31 and a powder suction component 32. The powder suction component 32 is disposed on the base 31 and has a first suction port 322 facing the powder outlet 21. The first suction port 322 is an elongated strip-shaped opening. An elongated strip-shaped opening refers to an opening whose length dimension is greater than its height dimension, for example, the conveying direction of the dispensing bottle 40. Thus, the elongated strip-shaped opening helps to form a narrow suction band, thereby increasing the air velocity, strengthening the suction, and making it easier to capture the powder generated during the dispensing process. In some specific embodiments, the powder suction component 32 is detachably connected to the base 31, which facilitates disassembly and maintenance, as well as cleaning, reducing the accumulation of dirt; and by replacing the base 31 with different heights, it is also easy to adapt to dispensing bottles 40 of different heights.

[0037] The base 31 extends towards the powder outlet 21 from the end near the first air intake 322, forming a first baffle 33. The side of the first baffle 33 facing away from the conveyor belt 11 is inclined towards the first air intake 322 to form a guide surface 332. That is, the first baffle 33 protrudes from the base 31 towards the powder outlet 21, thus forming a protrusion to facilitate airflow guidance. When air is drawn in through the first air intake 322, the first baffle 33 can block the air below the first air intake 322, reducing the amount of air drawn in below the first baffle 322 and allowing the first air intake 322 to draw in more air above the first baffle 322. Therefore, the air drawn in through the first air intake 322 can be focused, thereby improving the air intake efficiency. Furthermore, the side of the first baffle 33 facing away from the conveyor belt 11 is inclined toward the first air inlet 322 to form a guide surface 332. That is, a guide surface 332 inclined toward the first air inlet 322 is formed above the first baffle 33. When the first air inlet 322 is drawing air, the guide surface 332 can guide the airflow, so that the airflow flows directly toward the first air inlet 322, making the airflow more focused when the first air inlet 322 draws air; at the same time, it can also reduce the obstruction in the airflow process, thereby reducing the deceleration of the airflow or the probability of the airflow being affected by obstacles and generating turbulence, thereby further improving the suction efficiency, and reducing the probability of powder falling outside the dispensing bottle 40 due to turbulence and not being sucked up.

[0038] Below the powder outlet 21 is a powder filling area 22. A conveyor belt 11 transports the dispensing bottle 40 to the powder filling area 22, and a guide surface 332 extends into the powder filling area 22. When the dispensing bottle 40 is in the powder filling area 22, the powder can enter the dispensing bottle 40 through the powder outlet 21, thus completing the powder filling process. In this way, the guide surface 332 further extends into the powder filling area 22, getting closer to the dispensing bottle 40 and the powder outlet 21, thereby improving the airflow guidance effect near the powder outlet 21, further focusing the airflow, and improving suction efficiency, thus increasing dust collection efficiency. Simultaneously, the further extension of the guide surface 332 into the powder filling area 22 also means that the first windbreak 33 further extends into the powder filling area 22. Therefore, the first windbreak 33 can also block the air below it, thus making the airflow flowing upwards towards the first suction port 322 more focused.

[0039] A specific implementation of this utility model is as follows: The powder filling assembly 20 fills the powder, and the conveyor belt 11 transports the dispensing bottle 40 to below the powder outlet 21. The powder outlet 21 of the dispensing bottle 40 corresponds to the bottle opening, so the powder filling assembly 20 dispenses powder from the powder outlet 21, and the powder enters the dispensing bottle 40 to complete the powder dispensing process. During the powder dispensing process, the powder suction assembly 30 is opened so that the first air suction port 322 can suck up the powder. The first wind baffle 33 extends toward the powder outlet 21, thereby blocking the air below the first wind baffle 33 and guiding the air above the first wind baffle 33, that is, the air near the powder outlet 21 and the dispensing bottle 40, so that the airflow from the powder outlet 21 and the bottle opening of the dispensing bottle 40 converges toward the first air suction port 322, thereby driving the powder toward the first air suction port 322 to collect the powder, prevent the powder from falling outside the dispensing bottle 40 and causing pollution, and prevent the powder from spreading in the space where the powder filling device 1 is located.

[0040] The powder filling device 1 provided in this embodiment of the present invention realizes the dispensing of medicines through a conveyor belt 11 and a powder filling assembly 20. Powder is drawn in by a base 31 and a powder suction component 32 equipped with a first suction port 322 to prevent powder from falling outside the dispensing bottle 40 and causing contamination, and to prevent powder from spreading in the space where the powder filling device 1 is located. Furthermore, a first baffle 33 is provided on the powder suction component 32 to block the airflow below the first baffle 33 while allowing the airflow above the first baffle 33 to converge more smoothly towards the first suction port 322, thereby focusing the airflow and improving the suction efficiency of the first suction port 322 to better remove dust. In addition, the first suction port 322 is a long and narrow opening, which can also focus the airflow and increase the wind speed, thereby improving the suction efficiency. The powder filling device 1 provided in this embodiment of the present invention can focus the airflow and reduce airflow dispersion, thereby improving the suction efficiency and dust removal efficiency, thus reducing the impact on the cleanliness of the production workshop and the purity and safety of the medicine powder.

[0041] In some embodiments, see Figures 7 to 10 The first windbreak 33 has a first windbreak surface 331 on the side facing the conveyor belt 11. The first windbreak surface 331 can guide the airflow below the first windbreak 33 to avoid the airflow below from forming turbulence and affecting the airflow above the first windbreak 33, thereby avoiding affecting the suction efficiency of the first air intake 322.

[0042] In some embodiments, see Figures 7 to 10 The powder suction assembly 30 also includes a second windbreak 34, which is connected to the side of the first windbreak 33 facing the powder outlet 21. The side of the second windbreak 34 facing the conveyor belt 11 forms a second windbreak surface 341, and the side of the second windbreak 34 facing away from the conveyor belt 11 forms a second clearance surface 342. In other words, the second windbreak 34 extends further towards the powder outlet 21 than the first windbreak 33, thus being closer to the powder outlet 21 to further block the airflow below the second windbreak 34 and the first windbreak 33. Simultaneously, the second clearance surface 342 of the second windbreak 34 facing away from the conveyor belt 11, together with the guide surface 332, can guide the airflow, improving suction efficiency and thus dust removal efficiency. Furthermore, the second windbreak 34 is also easily adaptable to different structures of the dispensing bottle 40. For example, when the dispensing bottle 40 is a vial, the mouth of the vial protrudes more than the neck in the radial direction, making it prone to interference with the powder filling device 1. Therefore, a second baffle 34 is further provided. It is understood that the second baffle 34 is smaller in the vertical direction, making it convenient to place at the neck of the vial and simultaneously below the mouth of the vial. This allows the second baffle 34 to better cooperate with the vial. On the other hand, the second baffle 34 being located below the mouth of the vial can better receive the powder, preventing the powder from moving below the second baffle 34. The powder can be carried by the airflow above the second baffle 34 to the first suction port 322 for removal, thereby improving dust removal efficiency.

[0043] Specifically, the second windshield 34 is detachably connected to the first windshield 33. This facilitates the assembly and disassembly of the second windshield 34, making it easier to clean; it also facilitates the replacement of the second windshield 34, thereby adapting to different types or shapes of dispensing bottles 40 and improving the applicability of the powder filling device 1.

[0044] For some specific embodiments, see Figures 1 to 6The powder suction component 32 also has a first suction channel 321 connected to the first suction port 322. There are multiple powder outlets 21, so the conveyor belt 11 can transport multiple dispensing bottles 40 corresponding to the powder outlets 21 each time, allowing for simultaneous powder filling of multiple dispensing bottles 40, thereby improving filling efficiency. There are multiple first suction ports 322 and multiple first suction channels 321. The first suction channels 321 can have negative pressure, allowing the first suction ports 322 to suction air. After dust is sucked in by the first suction ports 322, it can enter the first suction channels 321 for subsequent processing. Each powder outlet 21 corresponds to a first suction port 322, and the multiple powder outlets 21 and multiple first suction ports 322 are arranged along the extension direction of the conveyor belt 11. During powder filling, each powder outlet 21 has a corresponding dispensing bottle 40 below it, allowing powder to be dispensed from the outlet 21 for filling. Simultaneously, each powder outlet 21 is also equipped with a corresponding first suction port 322 for dust removal, preventing a decrease in dust removal efficiency due to an insufficient number of first suction ports 322. Furthermore, multiple first suction ports 322 are arranged along the extension direction of the conveyor belt 11, meaning that multiple first suction ports 322 all draw air from the powder outlet 21 to the powder suction unit 32. Therefore, multiple first suction ports 322 can work together to draw air, thereby improving dust removal efficiency.

[0045] Specifically, see Figure 6 The dust suction assembly 30 also includes a suction connector 35, which is connected to the side of the dust suction component 32 away from the conveyor belt 11. In the extension direction of the conveyor belt 11, the length of the side of the dust suction component 32 closest to the conveyor belt 11 is greater than the length of the side connected to the suction connector 35. Multiple first suction ports 322 are located on the side of the dust suction component 32 closest to the conveyor belt 11. The suction connector 35 has a suction chamber 351, which communicates with multiple first suction channels 321. The multiple first suction channels 321 can converge on the side connected to the suction connector 35. After a negative pressure is formed in the suction chamber 351, a negative pressure is formed in the multiple connected first suction channels 321, thereby causing the corresponding first suction ports 322 to perform dust suction. Furthermore, the dust sucked in by the first suction ports 322 can flow into the suction chamber 351 through the first suction channels 321, facilitating subsequent centralized processing. In addition, this structure is easy to design, facilitates the installation of devices that provide negative pressure, and helps to reduce size.

[0046] Further, see Figures 6 to 9The dust suction assembly 30 also includes a suction tube 36 and a sealing ring 37. The suction connector 35 also has a connecting hole 352. The connecting end 361 of the suction tube 36 forms a sealing groove 362, the sealing ring 37 is disposed in the sealing groove 362, and the connecting end 361 is installed in the connecting hole 352. A third suction channel 363 is formed inside the suction tube 36, and the suction chamber 351 communicates with the third suction channel 363. The dust collected in the suction chamber 351 can be further carried away by the suction tube 36 to avoid dust accumulation and blockage in the suction chamber 351. At the same time, the suction tube 36 can also provide negative pressure to the suction chamber 351, so that the first suction port 322 can perform suction and dust removal. The connecting end 361 is provided with a sealing groove 362 and a sealing ring 37 to maintain a seal, thereby maintaining negative pressure in the suction tube 36 and the suction chamber 351 and preventing dust leakage from the suction tube 36 and the suction chamber 351; it also isolates the powder filling device 1 from the outside world, preventing the powder filling device from being contaminated by external factors. In some specific embodiments, the connecting end 361 is provided with multiple sealing grooves 362, which are arranged along the extension direction of the suction tube 36, and each sealing groove 362 is provided with a corresponding sealing ring 37, thereby further improving the sealing performance.

[0047] In some embodiments, see Figure 7 The base 31 also has a first clearance surface 311 on the other side facing the conveyor belt 11 to avoid interfering with the conveying and filling of the dispensing bottles 40 transported by the conveyor belt 11. The first clearance surface 311 is, for example, arc-shaped, so as to avoid the bottle body below the neck of the vial. It is understood that the first clearance surface 311 can be set according to the specifications and type of the dispensing bottles 40.

[0048] In some embodiments, see Figures 1 to 4The conveying assembly 10 also includes a conveying block 12 and a fixing clamp 13. The conveyor belt 11, the conveying block 12, and the fixing clamp 13 cooperate to convey the dispensing bottles 40 so that the bottle opening 41 of the dispensing bottle 40 is correspondingly arranged with the powder outlet 21 and the first air intake 322. The conveying block 12 is installed on the conveyor belt 11, and the fixing clamp 13 is located on the side of the conveying block 12 facing the base 31. The side of the conveying block 12 closer to the fixing clamp 13 is higher than the side of the conveying block 12 away from the fixing clamp 13. The fixing clamp 13 is used to fix the dispensing bottles 40 to prevent them from falling off the conveyor belt 11 during dispensing and conveying. By setting the fixing clamp 13, it helps to maintain the same spacing between the dispensing bottles 40, thereby facilitating the alignment with the powder outlet 21 and preventing the medicine from spilling out of the dispensing bottle 40 due to the alignment setting. The side of the conveyor block 12 closest to the fixed clamp 13 is higher than the side of the conveyor block 12 furthest from the fixed clamp 13. This helps to guide the airflow to the powder outlet 21, which can then be further guided by the guide surface 332 to the first suction port 322, thus improving suction efficiency and dust removal effect. Specifically, for example, the conveyor block 12 may have an arc-shaped surface, resulting in less obstruction and better airflow guidance.

[0049] In some embodiments, see Figures 1 to 4 The powder filling device 1 also includes a frame 60 and a powder bucket loading rack 50. A conveying assembly 10, a powder filling assembly 20, and a powder suction assembly 30 are mounted on the frame 60. The powder filling assembly 20 and the powder suction assembly 30 are located on opposite sides of the conveyor belt 11, perpendicular to the conveying direction. The powder bucket loading rack 50 and the powder suction assembly 30 are located on the same side of the conveyor belt 11. It is understood that the conveying direction refers to the transport sequence of the dispensing bottles 40. Thus, the powder filling assembly 20 and the powder suction assembly 30 can be located on opposite sides, reducing mutual interference and facilitating the placement of other components. Since the powder suction assembly 30 is relatively small, it is also convenient to place the powder bucket loading rack 50 and the powder suction assembly 30 on the same side, helping to fully utilize space and improve space utilization. The powder bucket loading rack 50 is used to hold powder buckets.

[0050] In some embodiments, see Figures 1 to 4The conveying assembly 10 also includes an inlet track 14, an inlet impeller 15, an outlet impeller 16, and an outlet track 17. The inlet track 14, inlet impeller 15, conveyor belt 11, outlet impeller 16, and outlet track 17 are connected in sequence. Dispensing bottles 40 are conveyed from other production lines to the powder filling device 1 via the inlet track 14. The inlet track 14 further conveys the dispensing bottles 40 to the inlet impeller 15. The inlet impeller 15 is provided with evenly spaced circumferentially arranged locking positions, in which the dispensing bottles 40 are positioned. This ensures that the distance between each dispensing bottle 40 is equal when transported to the conveyor belt 11, thus facilitating alignment with the powder outlet 21. The dispensing bottles 40 are conveyed from the inlet impeller 15 to the conveyor belt 11, where powder filling and suction are completed, and then they are conveyed to the outlet impeller 16. Since the inlet impeller 15 has fixed the spacing between the dispensing bottles 40, the dispensing bottles 40 can easily enter the slots of the outlet impeller 16 and be conveyed to the outlet track 17, which then transports the dispensing bottles 40 to other production lines. In this way, the components of the conveying assembly 10 are arranged in a coordinated manner, which helps to improve efficiency.
