[0027] Specifically, a first conveyor belt 226 is disposed on the fixed clamping arm 221 .

[0028] Specifically, the first conveyor belt 226 is arranged on the fixed clamping arm 221: the turning frame 21 is rotatably provided with a driving rubber roller 227 located on one side of the central rotating shaft 23 and connected to the fourth motor 26 arranged on the turning frame 21; the turning frame 21 is rotatably provided with a guide roller 228 located on the other side of the central rotating shaft 23; both ends of the fixed clamping arm 221 are rotatably connected with a pulley 229; the first conveyor belt 226 is wound around the driving rubber roller 227, the guide roller 228 and the pulleys 229 of the two centrally symmetrical fixed clamping arms 221.

[0029] In the above embodiment, the first motor 25 drives the central shaft 23 to rotate on the first support frame 24 through the cooperation of the sprocket and the chain, and drives the turning frame 21 to rotate on the first support frame 24. The two groups of clamping components 22 rotate with the turning frame 21.
