Description

Technical Field

[0001] The present invention relates to the technical field of capsules, and more specifically, to an automatic capsule filling machine. Background Art

[0002] A capsule refers to a small container for encapsulating drugs, usually composed of two hemispherical shells. One shell is used to hold drug powders or granules, and the other shell is used for closing. When in use, the drug powders or granules are filled into one shell, and then the other shell is closed with it to form a complete capsule. The design of the capsule facilitates patient taking because they can be easily swallowed, and the drug can be protected by the capsule to avoid premature release in the mouth or esophagus, ensuring that the drug is absorbed only after reaching the stomach or intestine.

[0003] According to the patent document: CN101305965B, a fully automatic capsule filling machine is disclosed, which includes a capsule dispensing turntable (5), a transmission mechanism, and a controller (3). The capsule dispensing turntable is provided with a plurality of stations, and at the corresponding stations, there are respectively a feeding device (2), a powder filling and metering device (4), a capsule tightening device (41), a discharging device (7), and a mold cleaning device (1). This capsule filling machine has the characteristics of good sealing of the capsule dispensing turntable, accurate powder loading, high capsule loading rate, strong production capacity, and having a capsule counting function.

The side of the top of the blanking columnar rotating rod positioning block 313 aligned with the front side material passing port 37 is a semi-circular cut surface. The left and right sides of the blanking columnar rotating rod positioning block 313 are respectively fixedly connected to side plates 312. The front sides of the two side plates 312 are fixedly connected to the rear side of the semi-circular connecting platform 22. The bottom of the inner sides of the two side plates 312 is fixedly connected to a blanking guiding U-shaped inclined plate connecting block 314. The inner top of the blanking guiding U-shaped inclined plate connecting block 314 is fixedly connected to a blanking guiding U-shaped inclined plate 315. The outer wall of the blanking columnar rotating rod 39 is fixedly connected to a material distributing rotating disk 316 on one side of the top of the blanking columnar rotating rod positioning block 313. The middle of the bottom of the material distributing rotating disk 316 is movably connected to a circular pressing inclined disk 317. The front and rear sides of the inner wall of the material distributing rotating disk 316 are respectively fixedly connected to material distributing pipes 318. The inner bottoms of the two material distributing pipes 318 are rotatably connected to material distributing pipe bottom covers 319. The tops of the two material distributing pipe bottom covers 319 are respectively fixedly connected to pulley connecting rods 3110. The inner tops of the two pulley connecting rods 3110 are rotatably connected to pulleys 3111. The outer walls of the two pulleys 3111 are respectively slidably connected to the front and rear sides of the bottom of the circular pressing inclined disk 317. The bottom of the circular pressing inclined disk 317 is inclined from the rear side to the front side. The capsule shell guiding frame 4 includes an inclined slide plate 41. The outer sides of the outer wall of the inclined slide plate 41 are respectively fixedly connected to support rods 44. The front and rear sides of the top of the inclined slide plate 41 are respectively provided with capsule slide rails 42. The rear sides of the two capsule slide rails 42 are respectively aligned with the tops of the capsule bottom shell blanking bin 27 and the capsule top shell blanking bin 211. The right side of the top of the inclined slide plate 41 is fixedly connected to a capsule shell inlet 43. The front and rear sides of the top of the capsule shell inlet 43 are respectively provided with blanking ports 45;

[0034] When the capsule needs to be filled with powder, first pour the top shell and the bottom shell of the capsule into the inner walls of the two feeding ports 45 opened by the capsule shell feeding port 43 respectively. Through the guidance of the inclined slide plate 41, the top shell and the bottom shell of the capsule slide along the capsule slide rail 42 to the capsule bottom shell feeding bin 27 and the capsule top shell feeding bin 211 respectively. At this time, start the equipment and control the second columnar rotating rod 215 to drive the rotating rod 218 to rotate. The rotation of the rotating rod 218 drives the irregular positioning disc 219 and the abutting block 2110 at its top to rotate together. When the abutting block 2110 rotates to the inner wall of the abutting groove 2113 opened by the rotation control disc 2111, the abutting block 2110 will push the rotation control disc 2111 to rotate by a certain angle. As the rotation control disc 2111 rotates, the semi-circular groove 2112 on it will align with a corresponding position on the columnar rotating rod 214, allowing the columnar rotating rod 214 to rotate intermittently under the action of an external driving force. This design ensures that the filling turntable 2114 can rotate at a predetermined rhythm. When one of the capsule bottom shell connecting grooves 2115 of the filling turntable 2114 rotates to the bottom of the feeding pipe 28, the inner wall of the feeding pipe 28 starts to feed the capsule bottom shell. When the capsule bottom shell connecting groove 2115 with the bottom shell rotates to the bottom of the front-side material distribution pipe 318, the material distribution pipe 318 starts to feed the powder to the inner wall of the feeding guide U-shaped inclined plate 315, and through the guidance of the feeding guide U-shaped inclined plate 315, it ensures that the powder smoothly enters the capsule bottom shell. When the loaded capsule bottom shell rotates and aligns with the second feeding pipe 212 through the filling turntable 2114, the second feeding pipe 212 drops the capsule top shell onto the capsule bottom shell and fixes their splicing by means of air pressure. The fixed capsule continues to rotate through the filling turntable 2114, and then the assembled and spliced capsule falls to the inner side of the discharge inclined slide plate 23 and is discharged through the discharge inclined slide plate 23, thus completing the entire automatic filling and encapsulation process of the capsule;

[0035] While the second columnar rotating rod 215 rotates, the transmission disk 216 on the outer wall and the crawler 217 drive the second transmission disk 310 to rotate. The rotation of the second transmission disk 310 drives the feeding columnar rotating rod 39 to rotate synchronously. The rotation of the feeding columnar rotating rod 39 drives the material distributing rotating disk 316 on its outer wall to rotate. As the material distributing rotating disk 316 rotates, the material distributing pipes 318 on it will sequentially rotate to the bottom of the material passing openings 37 opened in the material passing disk 36 at a predetermined rhythm. When the rear material passing opening 37 is aligned with the material distributing pipe 318, at this time, since the pulley 3111 slides along the circular actuating inclined disk 317, the bottom of the material distributing pipe 318 aligned with the rear material passing opening 37 is actuated by the circular actuating inclined disk 317, causing the pulley connecting rod 3110 to rotate and driving the bottom cover 319 of the material distributing pipe to close at the bottom of the material distributing pipe 318. At this time, the medicinal powder introduced by the funnel 38 will fall into the material distributing pipe 318 through the material passing opening 37. Subsequently, when the front material distributing pipe 318 rotates to a position aligned with the feeding guiding U-shaped inclined plate 315, since the pulley 3111 is no longer actuated by the circular actuating inclined disk 317, the bottom cover 319 of the material distributing pipe is flipped open by the action of gravity at the bottom of the material distributing pipe 318, enabling the medicinal powder to smoothly fall into the feeding guiding U-shaped inclined plate 315 and fall into the bottom shell of the capsule through its guiding action, completing the filling process of the medicinal powder;

[0036] As the feeding columnar rotating rod 39 rotates, the circular actuating inclined disk 317 will continuously change the force position of the pulley 3111 at its bottom, and then push the bottom cover 319 of the material distributing pipe to perform opening and closing operations through the pulley connecting rod 3110. This design ensures the accurate filling of the medicinal powder and avoids waste of the medicinal powder. The rotation of the feeding columnar rotating rod 39 is synchronous with the rotation of the second columnar rotating rod 215, and further makes the rotation rhythm of the material distributing rotating disk 316 and the filling rotating disk 2114 consistent, ensuring that each capsule receives an appropriate amount of medicinal powder at the correct time, and the capacity inside each material distributing pipe 318 is the capacity required for one-time filling of the capsule, further improving the filling accuracy and the reliability of the equipment. The entire automatic capsule filling machine realizes efficient and accurate capsule filling and encapsulation through precise mechanical design and synchronous control, greatly improving the production efficiency and reducing the labor cost, and is an important equipment on the automatic production line in the pharmaceutical industry.

[0037] Working principle of the present invention: When powder needs to be filled into the capsule, first pour the top shell and bottom shell of the capsule into the inner walls of the two feeding ports 45 opened in the capsule shell feeding port 43 respectively. Through the guidance of the inclined slide plate 41, the top shell and bottom shell of the capsule slide along the capsule slide rail 42 to the capsule bottom shell feeding bin 27 and the capsule top shell feeding bin 211 respectively. At this time, start the equipment, control the second columnar rotating rod 215 to drive the rotating rod 218 to rotate. The rotation of the rotating rod 218 drives the irregular positioning disc 219 and the abutting block 2110 at its top to rotate together. When the abutting block 2110 rotates to the inner wall of the abutting groove 2113 opened in the rotation control disc 2111, the abutting block 2110 will push the rotation control disc 2111 to rotate by a certain angle. As the rotation control disc 2111 rotates, the semi-circular groove 2112 on it will align with a corresponding position on the columnar rotating rod 214, allowing the columnar rotating rod 214 to rotate intermittently under the action of an external driving force. This design ensures that the filling turntable 2114 can rotate at a predetermined rhythm. When one of the capsule bottom shell connecting grooves 2115 of the filling turntable 2114 rotates to the bottom of the feeding pipe 28, the inner wall of the feeding pipe 28 starts to feed the capsule bottom shell. When the capsule bottom shell connecting groove 2115 with the bottom shell rotates to the bottom of the front-side distributing pipe 318, the distributing pipe 318 starts to feed the powder to the inner wall of the feeding guiding U-shaped inclined plate 315, and through the guiding of the feeding guiding U-shaped inclined plate 315, the powder is ensured to smoothly enter the capsule bottom shell. When the loaded capsule bottom shell rotates to align with the second feeding pipe 212 through the filling turntable 2114, the second feeding pipe 212 drops the capsule top shell onto the capsule bottom shell and fixes them together by means of air pressure. The fixed capsule continues to rotate through the filling turntable 2114, and then the assembled and spliced capsule falls to the inner side of the discharge inclined slide plate 23 and is discharged through the discharge inclined slide plate 23. When the second columnar rotating rod 215 rotates, the transmission disc 216 and the crawler 217 on the outer wall drive the second transmission disc 310 to rotate. The rotation of the second transmission disc 310 drives the feeding columnar rotating rod 39 to rotate synchronously. The rotation of the feeding columnar rotating rod 39 drives the distributing turntable 316 on its outer wall to rotate. As the distributing turntable 316 rotates, the distributing pipes 318 on it will sequentially rotate to the bottom of the feeding ports 37 opened in the feeding disc 36 at a predetermined rhythm. When the rear feeding port 37 aligns with the distributing pipe 318, at this time, due to the pulley 3111 sliding along the circular abutting inclined disc 317, the bottom of the distributing pipe 318 aligned with the rear feeding port 37 is abutted by the circular abutting inclined disc 317, causing the pulley connecting rod 3110 to rotate and driving the bottom cover 319 of the distributing pipe to close at the bottom of the distributing pipe 318. At this time, the powder introduced by the funnel 38 will fall into the distributing pipe 318 through the feeding port 37. Subsequently, when the front-side distributing pipe 318 rotates to the position aligned with the feeding guiding U-shaped inclined plate 315,Since the pulley 3111 is no longer actuated by the circular actuating cam plate 317, the bottom cover 319 of the dosing tube is flipped open under the action of gravity to open the bottom of the dosing tube 318, allowing the powder to smoothly fall into the downward guiding U-shaped cam plate 315 and fall into the bottom shell of the capsule through its guiding action.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
