Description

Technical Field

[0001] The utility model relates to the technical field of medicine, in particular to a semi-automatic capsule filling machine. Background Art

[0002] Capsule filling technologies primarily involve automated and precisely controlled equipment for efficient and accurate filling and packaging of capsules. These technologies include machines for adding drug powders and assembling capsules, as well as filling and filling technologies capable of handling different types of dosage forms, such as powders, liquids, and semi-solids.

[0003] Capsule filling machines are primarily used to fill capsule shells with medication or other substances and to lock the upper and lower bodies of these capsules. These machines not only focus on the complex filling process but also integrate inspection technology to meet the high production standards of the pharmaceutical industry.

[0004] In a traditional semi-automatic capsule filling machine, capsules in a hopper first enter an arrangement plate during operation. A vibrator then neatly arranges the separated upper capsule cap and lower capsule body on the upper and lower capsule fixing plates, respectively. The lower capsule shell in the capsule plate is then filled with powder / medicine. Finally, a locking plate is used to lock the upper and lower capsule shells together, completing the filling process. For example, Chinese utility model CN204864081U provides a semi-automatic capsule filling machine for filling capsules with medication. The machine comprises a workbench, a spring plate, a hopper, an electromagnetic vibrator, a locking device, and an arrangement plate. The workbench is provided with a spring plate, a locking device, and an electromagnetic vibrator. A spring plate is provided between the locking device and the electromagnetic vibrator. A hopper is provided on the electromagnetic vibrator, and an arrangement plate is mounted on the spring plate.

[0005] However, existing capsule filling machines face several technical drawbacks and challenges. For example, traditional semi-automatic capsule filling machines typically fill the material directly into the lower capsule shell. Furthermore, manual filling is often used during the filling process, making it difficult to control the actual amount of material filled. This can easily lead to inaccurate material quantities. In particular, excessive amounts of medication in the capsule can make it difficult to lock the upper and lower capsules together, and may even cause the capsule to rupture during closing. Conversely, too little filling can result in insufficient material in the capsule.

[0006] Therefore, the capsule filling machine in the prior art may cause large differences in the quality of the capsules during filling, even exceeding the limit, and the yield of qualified products is too low.

[0007] Therefore, it is urgent to develop a semi-automatic capsule filling machine to overcome the above-mentioned defects. Utility Model Content

[0054] Figure 1 This is a structural diagram of an embodiment of a semi-automatic capsule filling machine of the utility model. Figure 2 yes Figure 1 Schematic diagram of the structure of the semi-automatic capsule filling machine without the combined metering device installed. Figure 3 yes Figure 1 Exploded view of a semi-automatic capsule filling machine.

[0055] from Figures 1 to 3 As can be seen from the figure, the semi-automatic capsule filling machine may include a frame base 1, a lower capsule fixing plate 2, a combined metering device 3 ( Figure 1 and Figure 3 ), the pressure needle module 4, the locking pressure plate 5 and the scraping powder component 6 ( Figure 1 and Figure 3 shown in ).

[0056] In this embodiment, a receiving groove is provided on the top of the frame base 1, and the lower capsule fixing plate 2 is detachably provided in the receiving groove. A plurality of grooves are provided on the lower capsule fixing plate 2 for accommodating the lower capsule.

[0057] It should be noted here that the frame base 1 is an existing capsule filling machine structure. The frame base 1 shown in the figure is provided with a first push rod 11 connected to the lifting mechanism inside the frame base 1 and a second push rod 12 connected to the limiting mechanism inside the frame base 1 on both sides. Among them, the first push rod 11 can make the internal lifting mechanism rise and fall to drive the lower capsule fixing plate 2 to be lifted, so as to facilitate the removal and replacement of the lower capsule fixing plate 2 from the receiving slot. A limiting mechanism for selectively fixing the lower capsule fixing plate 2 is provided inside the frame base 1, which is used to lock the lower capsule fixing plate 2 in a fixed position in the receiving slot. Among them, the frame base 1 and the lifting mechanism, limiting mechanism, first push rod 11 and second push rod 12 inside the frame base 1 are all structures in the prior art. Therefore, the relevant structures will not be described in detail in this application. In the specific implementation, a frame base 1 with other structures can also be used, and this application does not limit them.

[0058] The locking pressure plate 5 is hinged to the second side wall of the frame base 1 , and is located in the frame base 1 so as to cover the accommodating groove, and the size and shape of the locking pressure plate 5 match the size and shape of the lower capsule fixing plate 2 .

[0059] Figure 4 yes Figure 1 Cross-sectional view of the combined metering device, Figure 5 yes Figure 3 Schematic diagram of the structure of the fixed frame, Figure 6 This is a schematic diagram of a combined metering device in an embodiment of the present invention when the push-pull bottom plate is located between the first area and the second area.

[0060] from Figures 3 to 6 As can be seen in FIG, the combined metering device 3 may include a fixed frame 31 , a powder blocking component 32 , a powder scraping groove 33 , a metering disc module and a push-pull bottom plate 35 .

[0061] Specifically, if Figure 3 As shown, a pair of powder blocking fixing members 311 are oppositely provided on two inner side walls of the fixed frame 31 , and both ends of the powder blocking component 32 are respectively connected to the corresponding powder blocking fixing members 311 .

[0062] In this embodiment, each powder blocking fixture 311 is formed by a slot provided on the corresponding inner wall of the fixing frame 31 , and both ends of the powder blocking component 32 are pluggably disposed in the corresponding slot.

[0063] The metering disc module includes at least one metering disc 34, such as Figure 6As shown, each metering disk 34 is provided with a plurality of first through holes 341. The number and position of the first through holes 341 on each metering disk 34 match the number and position of the grooves on the lower capsule fixing plate 2, and the metering disk 34 can be placed in the first area 36. The size of the metering disk 34 also matches the size of the first area 36.

[0064] The fixed frame 31 and the powder blocking component 32 can effectively position the metering disk 34 .

[0065] The figure only shows the situation where one metering disc 34 is placed in the fixed frame 31. In an optional embodiment, the metering disc module may include at least a metering disc 34 with a thickness of 1 mm, a metering disc 34 with a thickness of 2 mm, a metering disc 34 with a thickness of 4 mm, and a metering disc 34 with a thickness of 8 mm. Each metering disc 34 can be individually arranged in the first area 36 or combined and stacked in the first area 36. It should be noted that the number of metering discs 34 with the same thickness specification can also be multiple. If multiple metering discs 34 are combined and stacked, different canning quantities can be met. For example, if two metering discs 34 with a thickness of 4 mm are stacked, the several first through holes 341 of the two metering discs 34 correspond to each other one by one and are coaxially connected, forming an 8 mm measurement, which can meet the canning quantity of 8 mm. The specific selection and combination can be made according to the actual amount of capsules that need to be canned. The size specifications of various capsule models are listed below for reference:

[0066]

[0067] like Figure 5 and Figure 6 As shown, the area on one side of the powder blocking component 32 in the fixed frame 31 constitutes the first area 36, ​​and the first area 36 is hollow. The second area 37 is constituted by the area on the other side of the powder blocking component 32 in the fixed frame 31, and the size of the first area 36 is less than or equal to the size of the second area 37. Figure 4 and Figure 6 Although there is a certain gap between the metering disk 34 and the powder blocking component 32 shown in the figure, the picture is only to show that the metering disk 34, the fixed frame 31 and the powder blocking component 32 are different components arranged separately. During actual use, the metering disk 34 is completely in contact with the side walls of the fixed frame 31 and the powder blocking component 32 to avoid powder leakage.

[0068] The scraper groove 33 is arranged in the second area 37, and the size of the scraper groove 33 matches the size of the second area 37. In this embodiment, the scraper groove 33 is fixedly arranged in the second area 37, and the scraper groove 33 is connected to the lower capsule fixing plate 2 and / or the frame base 1 by a detachable connection assembly. In an optional embodiment, the detachable connection assembly includes a positioning pin assembly and a positioning hole assembly. The positioning pin assembly may include a plurality of positioning pins provided on the scraper groove 33, and the positioning hole assembly may include a plurality of positioning holes provided on the lower capsule fixing plate 2 or a plurality of positioning holes provided on the frame base 1. The fixing frame 31 is positioned and connected to the lower capsule fixing plate 2 through the positioning pins on the scraper groove 33 and the positioning holes on the lower capsule fixing plate 2 or the frame base 1. Figure 3 and Figure 5 The figure shows the situation where the positioning holes are located at the rack base 1.

[0069] The powder blocking component 32 is a detachable component. In some embodiments, the powder scraping groove 33 can extend to the bottom of the powder blocking component fixing part 311. When the powder blocking component 32 is removed from the fixed frame 31, the excess powder on the metering disk 34 can be directly swept into the powder scraping groove 33.

[0070] In some other embodiments, a connecting plate may be further provided at a position below the powder blocking part fixing member 311 in the fixed frame 31, with one side of the connecting plate extending to a position on one side of the metering disk 34 adjacent to the powder blocking part 32, and the other side of the connecting plate extending to the second area 37 to dock with the powder scraping groove 33, so that after the powder blocking part 32 is removed from the fixed frame 31, the excess powder on the metering disk 34 can be directly swept into the powder scraping groove 33 through the connecting plate.

[0071] The push-pull bottom plate 35 is provided on the inner periphery of the fixed frame 31 . The push-pull bottom plate 35 can move between the first area 36 and the second area 37 . The size of the push-pull bottom plate 35 matches the size of the first area 36 .

[0072] When the fixed frame 31 is set on the frame base 1, the first area 36 is located at the receiving groove of the frame base 1, the metering plate 34 located in the first area 36 covers the upper part of the receiving groove, and when the push-pull bottom plate 35 is located in the first area 36, ​​it is Figure 1 In the illustrated situation, the push-pull bottom plate 35 is located between the receiving groove and the metering disk 34 located at the bottom in the first area 36 . Figure 6 The push-pull bottom plate 35 is shown to be moved between the first area 36 and the second area 37. Figure 6 As shown, a push handle 351 can also be provided on the push-pull bottom plate 35 to facilitate the push-pull operation of the staff. Figure 3As shown, a pair of guide rails are relatively arranged on the two inner side walls of the powder blocking part fixing part 311 in the fixed frame 31, and each guide rail is located below the corresponding powder blocking part fixing part 311, so that the two side edges of the push-pull bottom plate 35 can be slidably set in the corresponding guide rails (the guide rails are not drawn in the figure).

[0073] In a specific application, a metering disc support (which may be a bump or other structure with a supporting function) may be further provided on the inner side of the fixed frame 31 for supporting the metering disc 34 , wherein the metering disc support is located above the guide rail.

[0074] Take the No. 1 capsule in the table above as an example. When it is actually canned, Figure 1 After the capsule filling machine is installed as shown, the push-pull bottom plate 35 is moved to the first area 36. At this time, the first area 36 includes the accommodating groove of the frame base 1, the lower capsule fixing plate 2, the push-pull bottom plate 35, and the metering disk module from bottom to top. The push-pull bottom plate 35 separates the lower capsule of the capsule in the groove of the lower capsule fixing plate 2 and the several first through holes 341 of the metering disk module between the lower capsule fixing plate 2 and the metering disk module. At this time, the push-pull bottom plate 35 serves as the bottom plate of the several first through holes 341 of the metering disk module, which can make the powder in the can accumulate in the first through holes 341. The staff weighs the target weight of the powder, the total amount of powder = the number of capsule particles (that is, the number of grooves of the lower capsule fixing plate 2 and the number of first through holes 341) × target weight × 1.02, adds the powder to the several first through holes 341 of the metering disk module, and uses the powder scraping component 6 to evenly fill the powder into the combination. In the metering disk module within the first area 36 of the metering device 3, if there is excess powder after filling, the powder blocking component 32 can be pulled out and the powder scraping component 6 can be used to scrape the excess powder into the powder scraping groove 33, and then the pressing needle module 4 is turned over so that its pressing needle is coaxial with the first through holes 341, and the needle assembly in the pressing needle module 4 is pressed down so that the powder forms a powder column in the first through hole 341 under the support of the push-pull bottom plate 35, and then the push-pull bottom plate 35 is moved to the second area 37. The powder column in the first through hole 341 falls into the corresponding lower capsule body in the lower capsule fixing plate 2 due to gravity or the continued downward thrust of the pressing needle module 4, and then the combined metering device 3 is removed, and according to the conventional operation of the prior art, the upper capsule fixing plate with the upper capsule is placed on the lower capsule fixing plate 2, and then the locking pressure plate 5 is used to lock the upper capsule cap with the lower capsule body to complete the capsule canning.

[0075] In an optional embodiment, the staff can disassemble the powder scraping groove 22 and pour the excess powder into the metering disc module. An additional powder scraping shovel can also be provided on the powder scraping component 6 to fill the excess powder in the powder scraping groove 33 back into the metering disc module.

[0076] Generally speaking, the diameter of the first through hole 341 in the metering disk 34 should be smaller than the size of the groove in the lower capsule fixing plate 2 to ensure that the material in the metering disk 34 can fall into the lower capsule shell therein.

[0077] The diameter of the pressing needle is smaller than the first through hole 341 and the groove in the lower capsule fixing plate 2 so that the pressing needle can pass through the corresponding first through hole 341 and the groove.

[0078] During the above-mentioned canning process, the powder scraping component 6 is in contact with the combined metering device 3 and is used in conjunction with the combined metering device 3 to prevent powder from scattering around the equipment during the metering process, thereby reducing the burden of cleaning and maintenance.

[0079] In specific applications, there is no limitation on the specific position of the powder scraping component 6 .

It should also be noted that the thickness of the fixing frame 31 is greater than the height of the multiple metering disks 34 stacked together.

[0083] The needle seat assembly is provided with a plurality of openings, and the number and position of the openings match the number and position of the grooves of the lower capsule fixing plate 2.

[0084] The needle assembly 41 includes several pressing needles, and each pressing needle is respectively arranged in a corresponding opening in the needle seat assembly, and each pressing needle can perform axial movement in the corresponding opening.

[0085] exist Figure 7In the illustrated embodiment, the needle pressing module 4 further includes a pressing rod assembly, which includes a pressing rod 42. The needle assembly 41 further includes a connecting plate 43. Specifically, the needle seat assembly is composed of a shell 46 with a cavity 461 therein, the first surface 462 of the shell and the second surface 463 of the shell are arranged opposite to each other, and the first surface 462 of the shell and the second surface 463 of the shell are spaced apart by a certain preset distance, wherein the distance between the first surface 462 of the shell and the second surface 463 of the shell can be designed according to user needs, and it is only necessary to ensure that the distance between the first surface 462 of the shell and the second surface 463 of the shell can allow the pressing needle to pass through the corresponding first through hole 341 and push the powder into the lower capsule shell in the lower capsule fixing plate 2. Several openings are provided on the first surface 462 of the shell, and a second through hole 4631 is provided on the second surface 463 of the shell.

In this embodiment, a handle is provided on the second end of the pressure rod 42 for ease of operation. In alternative embodiments, the pressure rod 42 may comprise a drive screw assembly, allowing the user to better control the position of the pressure rod 42 by rotating the drive screw.

[0087] In some other embodiments, the pressure rod 42 may also be composed of a connecting rod, and a spring is provided on the outer sleeve of the connecting rod, and the two ends of the spring may be respectively located between the handle and the housing 46, so that the connecting rod can be reset after the external force is removed.

[0088] In an optional embodiment, the pressure needle module 4 may also include a pressure transmitter assembly. The pressure transmitter assembly is a device that integrates a pressure sensor 44 and a signal processing circuit. It can not only convert pressure signals into electrical signals, but also convert these signals into standard current or voltage signals, so as to be directly connected to a control system or a data acquisition device. In this embodiment, the data acquisition device is a display 45. Pressure transmitters usually have higher accuracy and stability, and are suitable for real-time monitoring and feedback in industrial automation control systems. It should be noted here that the display 45 shows the force of the pressure needle on the powder pressing column on the push-pull base plate 35. If the pressure is too great, the powder column formed will be too hard. In a specific implementation, it is appropriate to keep the downward pressure at 50N to 150N.

[0089] In this embodiment, the pressure sensor 44 can be arranged between the pressure rod 42 and the connecting plate 43, or between the pressure rod 42 and the handle on the second end of the pressure rod 42. In some other embodiments, the pressure sensor 44 can also be arranged on any pressure pin, or between the first surface 431 of the connecting plate and the inner surface of the shell 46. The pressure sensor 44 is connected to the display 45 through an integrated signal processing unit. In an optional embodiment, the display 45 can be located on the pressure rod 42 or on the shell 46 of the pressure pin module 4 or on an external device end that can detect the pressure under the pressure pin. The pressure sensor 44 and the display 45 can be connected by a wire or by communication. Specifically, when the pressure sensor 44 and the display 45 are connected by a circuit, the output signal of the pressure sensor 44 is transmitted to the input port of the display 45 through a wire. When the pressure sensor 44 and the display 45 are connected in communication, it is usually based on serial communication (such as RS232, RS485, etc.) or Ethernet communication. The specific pressure transmitter component model can be Rosemount 3051GP or German BD|SENSORS series equipment, or other pressure transmitters can be used.

[0090] The user can clearly observe the force applied by the needle assembly 41 to the material through the display 45 so as to better control the force.

[0091] The semi-automatic capsule filling machine in this embodiment has the advantages of being easy to use, having good adaptability and a wide range of applications.

It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by a person skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology shall be within the scope of protection defined by the claims.
