At the same time, the cylindrical cam 9 and the incomplete gear 8 can rotate the vertical shaft 4 at a constant speed, so that the following four steps can be cyclically and sequentially executed:

firstly, when the incomplete gear 8 is in meshing transmission with the backflow gear 10, the right end of the turning rod 18 at the moment is carried on the first inclined surface of the cylindrical cam 9, the whole lower shaft 16 and the screwing sleeve 25 can be driven to be screwed downwards through the supporting effect of the cylindrical cam 9 on the turning rod 18 and the rotation of the transmission shaft 12, and when the screwing groove 25a rotates to cover the bottle cap, the second air cylinder 27 pushes the pressing column 26 to press the bottle cap, so that the bottle cap can be screwed downwards together with the screwing sleeve 25, and the bottle cap can be stably installed on the bottle.

Thirdly, when the right end of the turning rod 18 is carried on the low level surface of the cylindrical cam 9, the screwing sleeve 25 is static, and the second air cylinder 27 pulls the pressing column 26 to release the pressing state of the bottle cap.

Thirdly, when the incomplete gear 8 is meshed with the reversing gear 11 for transmission, the screwing sleeve 25 rotates reversely under the transmission action of the rope belt 15, the right end of the turning rod 18 is carried on the second inclined plane, and the screwing sleeve 25 is screwed upwards.

Fourthly, when the right end of the turning rod 18 is carried on the high-level surface of the cylindrical cam 9, the screwing sleeve 25 is static, the rotating disc 21 starts to rotate, and the next bottle cap can be conveniently installed.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
