A rotating ring 214 is fixedly installed at the position near the edge of the top of the connecting frame 213. Four connecting pipes 215 are fixedly connected to the bottom surface of the rotating ring 214. The bottom end of the connecting pipe 215 is fixedly connected to a vacuum chamber 216;

[0027] A suction and release component 22, which is arranged on the top of the mounting frame 11.

[0028] The suction and release component 22 includes a suction pump 224 fixedly installed on the top of the mounting frame 11. A suction pipe 225 is provided on the outer surface of the suction pump 224. The outer surface of the suction pipe 225 penetrates through the top of the mounting frame 11 and extends downward. The end of the suction pipe 225 is fixedly connected to a vacuum hood 221. The bottom surface of the vacuum hood 221 contacts the top surface of the rotating ring 214. By starting the suction pump 224 to generate negative pressure, and through the negative pressure effect of the suction pipe 225 in the vacuum hood 221. Since the bottom surface of the vacuum hood 221 is in close contact with the top surface of the rotating ring 214, and the vacuum chamber 216 is connected to the inner side of the vacuum hood 221 through the connecting pipe 215, all the vacuum chambers 216 in the area of the vacuum hood 221 generate negative pressure. At this time, under the action of the pressure difference, the stand-up bags in the feeding box 42 can be grabbed. The suction and release component 22 also includes a blower 226 fixedly installed on the top of the mounting frame 11. An air pipe 227 is provided on the outer surface of the blower 226. The outer surface of the air pipe 227 penetrates through the top of the mounting frame 11 and extends downward. The end of the air pipe 227 is fixedly connected to a positive pressure hood 222.
