Description

Technical Field

[0001] The invention relates to the technical field of capsule filling, in particular to a high-efficiency capsule filling machine. Background Art

[0002] In the pharmaceutical industry, capsule filling machines play an indispensable role in the preparation of capsule drugs. However, the capsule filling machines in the prior art generally face some challenges in the filling process, which limits the improvement of production efficiency. Most of the capsule filling machines in the prior art adopt a single filling head to fill one by one. The filling speed of this method is relatively slow, and it is difficult to meet the needs of large-scale production. At the same time, because the filling head needs to ensure that the rotating disk with the capsule shells is kept in a fixed state during filling, so as to accurately locate each capsule shell and fill it. However, this fixed state makes it impossible to continuously put empty capsule shells into the rotating disk, which causes discontinuity in the production process and further affects the overall production efficiency.

[0028] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0029] Please refer to the attached Figures 1 to 6 The present application provides a high-efficiency capsule filling machine, including a loader 1, a rotating disk 2, a sliding table 3, a filling head 4 and a press closure 5. The rotating disk 2 rotates under the drive of a driving mechanism 6. The rotating disk 2 is provided with a plurality of through holes 7 for placing capsule shells. A support plate 8 is provided at the bottom of the rotating disk 2. The support plate 8 is provided with a discharge chute 9. The loader 1 is provided on the left and right sides of the rotating disk 2 respectively. The loader 1 on the right is used to convey the lower shell of the capsule into the through hole 7, and the loader 1 on the left is used to convey the upper shell of the capsule into the through hole 7. The sliding table 3 is provided with a filling head 4 and a press closure 5. The sliding table 3 is slidably connected to the rotating disk 2, and the sliding table 3 reciprocates with the axis of the rotating disk 2 as the center. The filling head 4 is used to fill the lower shell in the through hole 7 with medicine, and the press closure 5 is used to press the upper shell onto the lower shell.

[0030] As the rotating disk 2 rotates, the lower shell of the capsule in the feeder 1 on the right side continuously falls into the through hole 7. Then, the filling head 4 is used to fill the medicine into the lower shell of the capsule, and then the upper shell of the capsule is placed into the through hole 7 by the feeder 1 on the left side, and finally the upper shell of the capsule is pressed downward by the press 5, so that the upper shell and the lower shell of the capsule are covered, and the medicine located in the lower shell of the capsule is sealed. When the rotating disk 2 rotates, the tray seals the lower end of the through hole 7. After the capsule filling is completed, the capsule rotates to the discharge trough with the rotating disk 2. The capsule at the discharge trough loses the support of the substrate, and the capsule falls out of the through hole 7 to complete the discharge. The sliding table 3 reciprocates with the axis of the rotating disk 2 as the center, so that the capsule shell can be continuously placed in the rotating disk 2. When filling and pressing, the sliding table 3 rotates at the same speed as the rotating disk 2, so that the filling head 4 and the press 5 always move synchronously with the capsule shell. The filling head 4 can fill multiple capsule shells at the same time, which improves the filling efficiency. During the entire process, the rotating disk 2 rotates continuously, and the feeder 1 also continuously puts capsule shells into the rotating disk 2, thereby improving the overall filling efficiency.

[0031] Specifically, the feeder 1 includes a capsule guide rail 10, the lower end of which is flush with or above the upper surface of the rotating disk 2, and a discharge hole 11 is provided at the bottom of the capsule guide rail 10. The capsule shell can be conveyed into the capsule guide rail 10 by a conveying device such as a conveyor belt or a conveyor. After the capsule shell enters the capsule guide rail 10, the capsule shell slides downward along the capsule guide rail 10. When the discharge hole 11 of the capsule guide rail 10 is aligned with the through hole 7 on the rotating disk 2, the capsule shell falls into the through hole 7.

[0032] Specifically, the filling head 4 includes a lifting platform 12, a pusher 13, a filling tube 14, a shell 15, a fan-shaped material tube 16, a rotating joint 17 and a feeding tube 18. The lifting platform 12 is connected to the sliding platform 3, the shell 15 is connected to the lifting platform 12, the filling tube 14 is communicated with the lower end of the shell 15, the fan-shaped material tube 16 is communicated with the side of the shell 15, the upper end of the fan-shaped material tube 16 is connected to the rotating joint 17, the rotating joint 17 is connected to the feeding tube 18, the pusher 13 includes a motor 19 and a screw rod 20, the motor 19 is connected to the screw rod 20, the motor 19 is located above the shell, and the screw rod 20 is located in the filling tube 14. The medicine to be filled enters the shell 15 through the feeding tube 18, the rotating joint 17 and the fan-shaped material tube 16, and the rotating joint 17 can keep the feeding tube 18 connected to the fan-shaped material tube 16 when the fan-shaped material tube 16 rotates. The motor 19 above the shell 15 drives the screw tube to rotate when working, and the screw rod 20 is located in the filling tube 14. At the same time, the filling tube 14 is connected to the shell. Therefore, the screw rod 20 is driven by electricity to rotate to push the medicine out of the filling tube 14, which can effectively control the filling of medicine into the capsule and effectively fill loose medicine. The lifting platform 12 can perform lifting and lowering movements, and the shell 15 can be driven up and down by the lifting platform 12. When filling medicine, the filling tube 14 is lowered, which is conducive to filling the medicine in the filling tube 14 into the capsule. The fan-shaped material tube 16 allows the medicine to enter the shell 15 evenly, which is conducive to filling medicine in the filling tubes 14 at different positions.

[0033] Specifically, the lifting platform 12 includes a lifting plate 21 and a telescopic rod 22. The lifting plate 21 is provided with a through hole passing through the telescopic rod 22. The main body of the telescopic rod 22 is connected to the lifting plate 21, and the movable end of the telescopic rod 22 is connected to the sliding platform 3. The telescopic rod 22 can be an electric telescopic rod 22 or a hydraulic telescopic rod 22. When the telescopic rod 22 is extended, it pushes the lifting plate 21 and the sliding platform 3 away from each other, thereby lifting the lifting plate 21. The housing is mounted on the lifting plate 21, thereby driving the filling tube 14 to approach and move away from the through hole 7. When filling the material, the lifting plate 21 is lowered, the filling tube 14 is closer to the lower shell of the capsule, or the filling tube 14 is extended into the groove and aligned with the lower shell of the capsule, so as to facilitate the accurate filling of the material into the lower shell of the capsule.

[0034] Specifically, the sliding platform 3 is provided with a plurality of slide grooves 23, and the filling tube 14 passes through the slide grooves 23. The filling tube 14 cooperates with the slide grooves 23 to improve the stability of the lifting rod and the sliding rod, reduce the displacement deviation of the filling tube 14, and effectively promote the filling of the medicine.

[0035] Specifically, the press sealer 5 includes a plurality of press bars 24, which are connected to the lifting plate 21 and pass through the slide slot 23. When the lifting plate 21 descends, the filling tube 14 is used to fill the lower shell of the capsule with medicine, and the press bars 24 are used to press the capsule, so that the upper shell of the capsule is connected with the lower shell of the capsule.

[0036] Specifically, a rotating shaft 25 is provided below the rotating joint 17, the lower end of the rotating shaft 25 is connected to the sliding table 3, the rotating shaft 25 is rotatably connected to a bearing seat 26 fixed to the ground, the bearing seat 26 is provided with a torsion spring 27, the torsion spring 27 is connected to the rotating shaft 25, the sliding table 3 is provided with an elastic element 28, and the rotating disk is provided with a plurality of protrusions 29 that cooperate with the elastic elements 28. When the rotating disk rotates, the sliding table 3 is pushed to rotate by the protrusions 29, and the protrusions 29 and the elastic elements 28 are separated after the sliding table 3 rotates and moves to a certain angle, so that the rotating disk is reset under the action of the torsion springs 27. Therefore, during the rotation of the rotating disk, the sliding table 3 continuously reciprocates, and is synchronized with the rotating disk when swinging forward, and can accelerate the reset when swinging backward.

[0037] Specifically, the sliding platform 3 is provided with a limit rod 30, and the limit rod 30 is provided with a push switch 31. The push switch 31 is electrically connected to the telescopic rod 22, and the bearing seat 26 is connected to the fixing frame 32. After the limit rod 30 rotates to a preset angle, it contacts the fixing frame 32. After the sliding platform 3 rotates to a preset angle, the push switch 31 of the limit rod 30 contacts the fixing rod, and the push switch 31 is pressed to extend the telescopic rod 22, thereby lifting the lifting plate 21. Then the limit rod 30 contacts the fixing frame 32, and the resistance to the rotation of the sliding platform 3 increases rapidly, and the protrusion 29 and the elastic element 28 are separated from each other, so that the sliding platform 3 rotates and resets.

[0038] Specifically, the elastic element 28 includes a swing rod 33, a spring 34 and a limit block 35. The swing rod 33 is rotatably connected to the sliding table 3. One end of the swing rod 33 is connected to the spring 34, and the other end of the spring 34 is connected to the limit block 35. The limit block 35 is fixedly connected to the rotating table. The swing rod 33 is limited by the spring 34. When the protrusion 29 contacts the swing rod 33, the protrusion 29 has a tendency to push the swing rod 33 to rotate, so it is necessary to overcome the elastic potential energy of the spring 34. When the limit rod 30 is not in contact with the fixed frame 32, the protrusion 29 pushes the sliding table 3 to rotate through the elastic element 28. When the limit rod 30 contacts the fixed frame 32, the limit rod 30 cannot pass over the fixed frame 32. At this time, the protrusion 29 continues to move to push the swing rod 33 to rotate, so that the protrusion 29 passes over the swing rod 33. Then the sliding table 3 is reset under the action of the torsion spring 27, and the turntable continues to rotate under the action of the driving mechanism 6.

[0039] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
