[0037] (i) The motor 104 is started, and the motor 104 drives the transmission belt 107 to move through the rotating roller 103, and drives the tank body 3 to move through the transmission belt 107, and drives all the rotating rollers 103 to rotate through the transmission belt 107. When the rotating roller 103 rotates, it drives the fourth rotating shaft 410 to rotate, and the fourth rotating shaft 410 drives the second connecting rod 412 to rotate, and the second connecting rod 412 drives the first connecting rod 409 to move through the fourth connecting rod 414, and drives the driving block 408 to move through the first connecting rod 409, and the driving block 408 drives the slider 407 to slide along the limit block 402, and the slider 407 drives the driving rod 406 to move, and the driving rod 406 drives the disc 416 to slide along the inner wall of the fixed cylinder 403, and the gas in the air box 404 is sent to the nozzle 206 through the air supply pipe 405 through the driving rod 406, and is sprayed out through the nozzle 206.

[0038] (ii) When the rotating roller 103 rotates, it drives the third rotating shaft 212 to rotate, and drives the first gear 213 to rotate through the third rotating shaft 212. The first gear 213 drives the second rotating shaft 209 to rotate through the second gear 214. The second rotating shaft 209 drives the moving plate 208 to move. The moving plate 208 drives the vertical groove 211 to slide along the inner wall of the vertical groove 203. The moving plate 208 drives the jet head 206 to move through the connecting rod 215. Under the action of the mounting ball 205, the jet head 206 starts to rotate. When the jet head 206 rotates, the gas transmitted from the air supply pipe 405 is ejected at multiple angles, and the bottle caps that are not securely installed on the multi-directional inflation mechanism 2 are blown up by the jet.

[0039] (iii) The blown-off bottle caps fall into the collecting hole 502, and enter the collecting box 503 through the collecting hole 502. When the rotating roller 103 rotates, it drives the sixth rotating shaft 508 to rotate, and the sixth rotating shaft 508 drives the second cam 509 to rotate. When the receiving and sorting mechanism 50 rotates, it pushes the moving block 505 to slide along the inner wall of the side groove 108. When the moving block 505 moves, it drives the impact rod 504 to impact the placement block 501, thereby avoiding congestion between the bottle caps and preventing them from falling into the collecting box 503.
