[0029] Embodiment 1:

[0030] Figure 1 and Figure 2An embodiment of the transmission device of the present utility model for a capsule filling machine is shown. The transmission device for the capsule filling machine in this embodiment includes a mounting frame 1, a rotating seat 2, a lifting shaft 3, and a rotatably arranged cam 4. The rotating seat 2 is rotatably arranged on the mounting frame 1, the lifting shaft 3 is arranged to be lifted and rotated on the mounting frame 1, a indexing box 5 and a lifting seat 6 are provided on the mounting frame 1, the rotating shaft 41 of the cam 4 is in transmission connection with the indexing box 5, the indexing box 5 is connected to the rotating seat 2 and is connected to the lifting shaft 3 through a rotating transmission assembly 7, and the lifting seat 6 abuts against the contour curve of the cam 4 and is connected to the lifting shaft 3.

[0031] During use, the rotating shaft 41 of the cam 4 is connected to a power mechanism. The rotational movement of the cam 4 drives the lifting movement of the lifting seat 6. At the same time, the indexing box 5 drives the rotational movement of the rotating seat 2, and the indexing box 5 and the rotating transmission assembly 7 drive the rotational movement of the lifting shaft 3. The overall structure layout of this transmission device for the capsule filling machine is reasonable and occupies a small space.

[0032] Further, in this embodiment, the rotating transmission assembly 7 includes a first transmission gear 71 and a second transmission gear 72 that are engaged with each other. The first transmission gear 71 is arranged on the lifting shaft 3, and the second transmission gear 72 is arranged on the mounting frame 1 and is in transmission connection with the indexing box 5. Through the meshing transmission of the first transmission gear 71 and the second transmission gear 72, the transmission is stable.

[0033] Further, in this embodiment, the width of the first transmission gear 71 is at least twice as large as that of the second transmission gear 72, which is convenient for the two to slide axially towards each other. Of course, in other embodiments, it can also be that the width of the second transmission gear 72 is at least twice as large as that of the first transmission gear 71, or the first transmission gear 71 and the second transmission gear 72 are of the same size, as long as it is satisfied that within the lifting range of the lifting shaft 3, the first transmission gear 71 and the second transmission gear 72 remain engaged.

[0034] Further, in this embodiment, the rotating transmission assembly 7 further includes a third transmission gear 73. The third transmission gear 73 is arranged on the indexing box 5 and is engaged with the second transmission gear 72. That is to say, the indexing box 5 and the lifting shaft 3 are in transmission connection through multiple meshing gears in sequence, further improving the stability of the transmission.

[0035] Further, in this embodiment, the indexing box 5 has an input shaft 51, a first output shaft 52, and a second output shaft 53. The third transmission gear 73 is arranged on the first output shaft 52, the second output shaft 53 is connected to the rotating seat 2, and the input shaft 51 is connected to the rotating shaft 41.

[0036] Further, in this embodiment, the input shaft 51 and the rotating shaft 41 are connected through a sprocket mechanism 8. Using the sprocket mechanism 8 for transmission occupies less space and is convenient for the overall layout.

[0037] Further, in this embodiment, the sprocket mechanism 8 includes a driving sprocket 81, a driven sprocket 82 and a chain 83. The driving sprocket 81 is arranged on the rotating shaft 41, the driven sprocket 82 is arranged on the input shaft 51, and the chain 83 is wound around the driving sprocket 81 and the driven sprocket 82. The driving sprocket 81 rotates with the rotating shaft 41 and drives the driven sprocket 82 to rotate through the chain 83. The driven sprocket 82 drives the indexing box 5 to operate through the input shaft 51. The indexing box 5 is a commercially available conventional component.

[0038] Further, in this embodiment, a tensioning mechanism 11 for tensioning the chain 83 is arranged on the mounting frame 1. The tensioning mechanism 11 tensions the chain 83 to prevent the chain 83 from being too loose and affecting the transmission effect.

[0039] Further, in this embodiment, a transmission shaft 12 is arranged on the mounting frame 1 in a lifting manner, and the transmission shaft 12 is connected to the lifting seat 6. The transmission shaft 12 is connected to the lifting seat 6 and moves up and down with the lifting seat 6, and can drive another executing component to move up and down.

[0040] Preferably, the indexing box 5 performs six-index intermittent rotation. The second output shaft 53 transmits the motion to the rotating seat 2 to ensure that the rotating seat 2 can perform six-index intermittent motion. The first output shaft 52 is coaxially connected to the second output shaft 53, that is, the same shaft, and performs six-index intermittent motion, and transmits the motion to the lifting shaft 3 through each gear, so that the lifting shaft 3 performs intermittent rotational motion. Since the module of the second transmission gear 72 and the third transmission gear 73 is the same, and the module of the first transmission gear 71 and the second transmission gear 72 is the same, and the tooth number ratio is 3:1, the lifting shaft 3 performs two-index intermittent motion. When the rotating shaft 41 rotates one week, the rotating seat 2 rotates 1 / 6 week, and the lifting shaft 3 rotates 1 / 2 week, and the transmission ratio is 6:1:3.
