Description

Technical Field

[0001] This utility model relates to a capsule filling machine, and more particularly to a powder filling mechanism. Background Technology

[0002] Capsule filling equipment requires filling medicine powder into capsules. During operation, it is necessary to carry out corresponding stirring and filling output. Stirring mixes the medicine powder in the hopper (such as powder hopper) and prevents clumping. Filling output outputs the stirred medicine powder in the hopper to fill the capsules.

[0003] In the hopper mixing and filling device of a capsule filling equipment, a corresponding drive structure drives the filling transmission spindle and the stirring transmission hollow shaft in the hopper mixing and filling device to rotate, thereby driving the corresponding stirring components (such as stirring rods, stirring scrapers, or stirring blades) and filling components (such as filling screws) in the hopper body to rotate and operate in coordination. The hopper mixing and filling device is mounted on a support rotating arm, which drives the hopper mixing and filling device to switch positions between the filling position and the non-filling position. A gear drive structure (see CN221845527U, a capsule machine powder filling device, including a corresponding planetary gear set) can be set between the filling transmission spindle and the stirring transmission hollow shaft for linkage. The stability of the hopper mixing and filling device during operation and its position switching with the support rotating arm is crucial. During the filling process, the powder needs to be filled downwards, which will also generate a corresponding upward reaction force, placing a burden on the structure and affecting its stability and service life. Therefore, a reasonable support structure and power transmission structure help to improve and optimize the operational stability of the filling mechanism. Utility Model Content

[0004] In view of the technical problems existing in the background art, the present invention aims to provide a capsule powder filling mechanism with relatively stable operation.

[0005] Various optimizations or supplementary explanations can be made to the above technical solutions. A capsule powder filling mechanism includes a hollow support column, a hollow rotating shaft, a power spindle, a spindle drive motor, a rotating shaft drive component, a hopper support arm, and a hopper mixing and filling device. The hopper mixing and filling device includes a hopper body, a filling transmission spindle, and a mixing transmission hollow shaft.

The filling transmission spindle and the mixing transmission hollow shaft are connected by a linkage component. The hollow support column is mounted on the platform of the frame. The hollow rotating shaft is connected and configured within the hollow support column. The power spindle is connected and configured within the hollow rotating shaft. The upper end of the power spindle is connected to the upper end of the filling transmission spindle, and the lower end of the power spindle is connected to the spindle drive motor. The hopper support arm is connected to the hollow rotating shaft and is located above the hollow support column. The lower end of the hollow rotating shaft is connected to the rotating shaft drive component. Based on this, the following additions or optimizations can be made.

[0006] For example, the silo body is connected to the silo support swing arm, the filling drive spindle and the stirring drive hollow shaft are connected and configured on the silo body, and the silo stirring and filling device also includes a mounting plate, which is connected and installed on the silo body. The mounting plate is located at the upper end of the silo body and has a rotating support part for the stirring drive hollow shaft to be connected.

[0007] Further optimization involves a linkage component including a central pulley, a gear ring with internal teeth, and a synchronous belt. The central pulley is connected to the upper end of the filling drive spindle, and the gear ring is connected to the upper end of the stirring drive hollow shaft. The internal teeth of the gear ring surround the central pulley. A transition pulley set is also provided on the mounting plate. The gear ring and the central pulley are connected by a synchronous belt. The transition pulley set is distributed between the gear ring and the central pulley, and the synchronous belt is wound around the transition pulley set.

[0008] For example, the linkage components include planetary gear mechanisms.

[0009] For example, the upper end of the power spindle is provided with a first transmission wheel, and the upper end of the filling transmission spindle is provided with a second transmission wheel. The first transmission wheel and the second transmission wheel are connected by a first transmission belt. The first transmission wheel is located above the power spindle, and the second transmission wheel is located above the filling transmission spindle.

[0010] For example, the spindle drive motor is located below the platform, the spindle drive motor is connected to the third transmission wheel, the lower end of the power spindle is provided with the fourth transmission wheel, the third transmission wheel and the fourth transmission wheel are connected by the second transmission belt; the fourth transmission wheel is located below the hollow rotating shaft.

[0011] For example, the rotating shaft drive component includes a drive cylinder, and the lower end of the hollow rotating shaft is provided with a drive arm, which is connected to the drive cylinder in a transmission manner.

[0012] The spindle drive motor is mounted on the table panel and located on the lower side of the table panel. The rotating shaft drive component is also mounted on the table panel and located on the lower side of the table panel.

[0013] In addition, the tabletop has a through hole, and the hollow support column is located above the through hole. The lower end of the hollow support column is positioned and sleeved with the through hole. The lower end of the through hole has a connecting plate. The connecting plate, the tabletop, and the hollow support column are connected by fasteners. The hollow support column and the connecting plate cooperate to clamp the tabletop.

[0014] In addition, the connecting plate has a through hole for the hollow rotating shaft to pass through. A plane bearing is fitted on the lower side of the connecting plate, and a first locking nut is fitted on the lower side of the plane bearing. The first locking nut is threaded onto the hollow rotating shaft. The hopper support arm is locked onto the hollow rotating shaft. The hopper support arm has a mounting hole that fits onto the hollow rotating shaft. The hollow rotating shaft has a limiting ring that limits and fits onto the lower side of the hopper support arm. A second locking nut is fitted on the upper side of the hopper support arm and is threaded onto the hollow rotating shaft. The limiting ring is located at the upper end of the hollow support column. A combined bearing is fitted between the upper end of the hollow support column and the upper limiting ring, and the combined bearing is fitted between the hollow support column and the hollow rotating shaft. A rotary support bearing is also provided between the lower end of the hollow support column and the hollow rotating shaft.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Referring to the accompanying drawings, the capsule powder filling mechanism in this embodiment includes a hollow support column 10, a hollow rotating shaft 20, a power spindle 30, a spindle drive motor 35, a rotating shaft drive component 21, a hopper support rotating arm 60, and a hopper stirring and filling device 7.

[0033] The silo mixing and filling device includes a silo body 70, a filling drive spindle 71, and a stirring drive hollow shaft 72. The silo mixing and filling device 70 is mounted on a silo support rotating arm 60, which supports the silo mixing and filling device 70. The filling drive spindle 71 is disposed in the stirring drive hollow shaft 72. When the filling drive spindle 71 and the stirring drive hollow shaft 72 are driven to rotate, the stirring component 73 and the filling component 74 in the silo body 70 can rotate respectively to cooperate with the filling of the powder. This is a mature technology. The filling drive spindle 71 and the stirring drive hollow shaft 72 are connected by a linkage component, that is, the filling drive spindle 71 can drive the stirring drive hollow shaft 72 to rotate through the linkage component. The silo body 70 may include an upper cylinder and a lower cylinder, which are respectively connected to the upper and lower sides of the silo support rotating arm 60.

[0034] The hollow support column 10 is installed on the table panel 90 of the frame. The table panel 90 is the frame table of the whole machine. The table panel 90 can provide overall support for the hollow support column 10 and its structure.

[0035] The hollow rotating shaft 20 is connected and configured in the hollow support column 10, and the hollow support column 10 cooperates to provide rotational support for the hollow rotating shaft 20;

[0036] The power spindle 30 is connected and configured in the hollow rotating shaft 20, and the hollow rotating shaft 20 cooperates to provide rotational support for the power spindle 30;

[0037] The upper end of the power spindle 30 is connected to the upper end of the filling transmission spindle 71. The rotation of the power spindle 30 drives the filling transmission spindle 71 to rotate, and the filling transmission spindle 71 then drives the stirring transmission hollow shaft 72 to rotate through the linkage component. The lower end of the power spindle 30 is connected to the spindle drive motor 35 (such as a servo motor with a reducer), and the spindle drive motor 35 drives the power spindle 30 to rotate.

[0038] The hopper support arm 60 is connected to the hollow shaft 20. The hollow shaft 20 supports the hopper support arm 60 and drives it to rotate, such as switching positions back and forth (e.g., switching positions between filling and non-filling stations). The hopper support arm 60 is located above the hollow support column 10. The lower end of the hollow shaft 20 is connected to the shaft drive component 21, which drives the hollow shaft 20 to rotate (back and forth).

[0039] Its working principle is as follows: the platform 90 of the frame supports the hollow support column 10, thereby supporting other structures on the hollow support column 10. The spindle drive motor 35 transmits power to the hopper mixing and filling device 7 through the power spindle 30, causing the filling transmission spindle 71 and the mixing transmission hollow shaft 72 to operate accordingly. The spindle drive motor 35 does not need to be supported by the hopper support swing arm 60, and the load on the hopper mixing and filling device 7 on the hopper support swing arm 60 is relatively light, thereby lowering the center of gravity of the entire capsule filling mechanism and making the operation relatively more stable. In particular, the hopper mixing and filling device 7 is directly connected to the filling transmission spindle 71 and the mixing transmission hollow shaft 72 by a linkage component. With the power transmission, the transmission structure is relatively stable, and the speed ratio between the filling transmission spindle 71 and the mixing transmission hollow shaft 72 is stable, resulting in relatively stable operation.

[0040] The capsule powder filling mechanism has a reasonable structural layout. The platform 90 of the frame supports the hollow support column 10 and other structures on the column (such as the hopper support arm 60). The spindle drive motor 35 transmits power to the hopper mixing and filling device 7 on the hopper support arm 60 through the power spindle 30. The spindle drive motor 35 does not need to be installed on the hopper support arm 60, so the load on the hopper support arm 60 is relatively reduced and the operation is relatively more stable. The support structure and power transmission structure help to improve the operational stability and service life of the filling mechanism.

[0041] Based on the above embodiments, the following optimizations or further explanations can be made.

[0042] For example, the silo body 70 can be connected to the silo support swing arm 60, and the filling transmission spindle 71 and the stirring transmission hollow shaft 72 can be connected and configured on the silo body 70.

[0043] In addition, the silo mixing and filling device 7 also includes a mounting plate 50, which is connected and installed on the silo body 70 (for example, the mounting plate 50 is set at the upper end of the silo body 70). The mounting plate 50 has a rotating support part 51 (such as including a support cylinder, bearing, etc.) for the mixing drive hollow shaft 72 to be connected and installed. This allows the mounting plate 50, the mixing drive hollow shaft 72 on it, and the filling drive spindle 71 in the middle to form a combined assembly structure. The mounting plate 50 provides the mounting for them, which is convenient for assembly. This assembly structure can be pre-assembled and then the whole assembly structure can be added to the silo body 70, which is more convenient.

[0044] There are various methods for linking components, such as using a gear linkage reduction structure, like the gear drive structure in the background art, or the linking components including a planetary gear mechanism. For example, the linking components in the figure include a central pulley 80, a gear ring 81 with internal teeth 84 (such as a gear disc structure), and a synchronous belt 82. The central pulley 80 is driven to the upper end of the filling transmission spindle 71, and the gear ring 81 is driven to the upper end of the stirring transmission hollow shaft 72. The internal teeth 84 of the gear ring 81 surround the central pulley 80, meaning the central pulley 80 mounted on the stirring transmission hollow shaft 72 is located at the center of the gear ring 81 mounted on the stirring transmission hollow shaft 72. In addition, the mounting plate 50 also has a transition wheel assembly 83 (containing several transition units). The gear ring 81 (which can be configured in terms of quantity and position according to the requirements of the synchronous belt 82 drive winding) is connected to the central pulley 80 via the synchronous belt 82 drive. The transition pulley set 83 is distributed between the gear ring 81 and the central pulley 80. The synchronous belt 82 is wound around the transition pulley set 83. When running, the teeth on the front of the synchronous belt 82 engage with the teeth of the central pulley 80 for transmission. The back of the synchronous belt 82 can be wound around the transition pulley set 83. The teeth on the front of the synchronous belt 82 can also be engaged by the transition pulley set 83 to fit against the inner teeth 84 of the gear ring 81 for transmission. The mounting plate 50 in the figure includes a base plate 52, an intermediate plate 54, and a cover plate 53. A space for accommodating the gear ring 81 is formed between the base plate 52 and the intermediate plate 54. The intermediate plate 54 is mounted on top of the base plate 52, and the cover plate 53 is mounted on top of it. The intermediate plate 54 is located between the base plate 52 and the cover plate 53. The axle 85 of the transition gear set 83 can be mounted on the intermediate plate 54. A planar thrust bearing can be installed between the base plate 52 and the gear disc of the upper gear ring 81. A planar thrust bearing can also be installed between the gear disc of the gear ring 81 and the upper central pulley 80.

[0045] The power spindle 30 has a first transmission wheel 31 at its upper end, and the filling transmission spindle 71 has a second transmission wheel 32 at its upper end. The first transmission wheel 31 and the second transmission wheel 32 are connected by a first transmission belt. The first transmission wheel 31 is located above the power spindle 30, and the second transmission wheel 32 is located above the filling transmission spindle 71. This single transmission structure—the first transmission wheel 31, the first transmission belt, and the second transmission wheel 32—is sufficient to connect the power spindle 30 and the filling transmission spindle 71, transmitting power. The transmission structure is relatively simple, easy to assemble, and easy to debug, avoiding the more complex structures of multiple transmission sets. Alternatively, a tensioning wheel 36 can be configured on the mounting plate 50 to tension the first transmission belt.

[0046] For example, the spindle drive motor 35 is located below the platform 90. The spindle drive motor 35 is connected to a third transmission wheel 33, and a fourth transmission wheel 34 is located at the lower end of the power spindle 30. The third transmission wheel 33 and the fourth transmission wheel 34 are connected by a second transmission belt. This single transmission structure—the third transmission wheel 33, the second transmission belt, and the fourth transmission wheel 34—is sufficient to connect the spindle drive motor 35 and the power spindle 30, transmitting power. The transmission structure is relatively simple, easy to assemble, and easy to debug. The fourth transmission wheel 34 is located below the hollow rotating shaft 20.

[0047] For example, the rotating shaft drive component 21 includes a drive cylinder, and the lower end of the hollow rotating shaft 20 is provided with a drive arm 22. The drive arm 22 is connected to the drive cylinder for transmission, which can drive the hollow rotating shaft 20 to rotate back and forth, making it convenient to switch between the filling station and the non-filling station.

[0048] For example, the spindle drive motor 35 is installed and connected to the table panel 90, with the spindle drive motor 35 located on the lower side of the table panel 90. The shaft drive component 21 is also installed and connected to the table panel 90, with the shaft drive component 21 located on the lower side of the table panel 90. This structure is more reasonable and relatively compact. The table panel 90 directly supports the spindle drive motor 35 and the shaft drive component 21, resulting in better overall integrity and facilitating transportation and handling. Brackets or other supports can be set up for installation and connection as needed.

[0049] In addition, to increase operational stability, the structure can be improved as follows: A through hole 91 is provided on the tabletop 90, and the hollow support column 10 is located above the through hole 91. The lower end of the hollow support column 10 is positioned and sleeved with the through hole 91 for easy and quick installation. A connecting plate 92 is provided at the lower end of the through hole 91. The connecting plate 92, the tabletop 90, and the hollow support column 10 are connected by fasteners (such as screws). The fasteners pass through the corresponding connecting holes of the connecting plate 92, the tabletop 90, and the hollow support column 10 in sequence, allowing the hollow support column 10 and the connecting plate 92 to clamp the tabletop 90 for installation and fixation. This structure makes the installation of the hollow support column 10 relatively convenient, while also ensuring its stability on the tabletop 90. The support structure on the top is more stable, and even if the hollow support column 10 is subjected to an upward reaction force during the filling process, the reaction force can be shared by the connecting plate 92 and the platform 90. Furthermore, the connecting plate 92 has a through hole for the hollow rotating shaft 20 to pass through. A flat bearing 93 is mounted on the lower side of the connecting plate 92, and a first locking nut 94 is mounted on the lower side of the flat bearing 93. The first locking nut 94 is threaded onto the hollow rotating shaft 20. The first locking nut 94, connected to the hollow rotating shaft 20, helps to press the flat bearing 93 onto the connecting plate 92 for installation. The flat bearing 93 can support the rotation of the hollow rotating shaft 20, and it can also help the connecting plate 92 share the upward reaction force of the hollow rotating shaft 20 during the filling process. The connecting plate 92... The platform 90 can withstand pressure, reducing or even avoiding the direct impact of the upward reaction force of the hollow shaft 20 on other structures, thereby increasing operational stability and service life. The hopper support arm 60 can be locked onto the hollow shaft 20 for installation. For example, the hopper support arm 60 has mounting holes that fit onto the hollow shaft 20. The hollow shaft 20 has a limiting ring 23, which limits the lower side of the hopper support arm 60. The upper side of the hopper support arm 60 is equipped with a second locking nut 24, which is threaded onto the hollow shaft 20. When the hopper support arm 60 is fitted onto the hollow shaft 20, the limiting ring 23 blocks the movement from below. This ensures smooth positioning, and the second locking nut 24 then locks the hopper support arm 60 against the upper side of the limiting ring 23, achieving installation and connection. The limiting ring 23 is located at the upper end of the hollow support column 10. A combined bearing 25 is provided between the upper port of the hollow support column 10 and the upper limiting ring 23. The combined bearing 25 is fitted between the hollow support column 10 and the hollow rotating shaft 20, that is, a combined bearing 25 is set between the upper port of the hollow support column 10 (which can be set as a stepped opening) and the limiting ring 23 of the hollow rotating shaft 20 to cooperate in bearing axial and radial loads. A rotary support bearing 26 is also provided between the lower port of the hollow support column 10 and the hollow rotating shaft 20, which can be fitted with a corresponding stepped structure and retaining ring for installation.In addition, corresponding bearings will be provided between the hollow rotating shaft 20 and the power spindle 30 to support rotation. For example, corresponding bearings will be provided at the upper and lower ends, which is a mature technology.
