[0045] At the loading station, the paper bags are placed on the translation plate 12, and the paper bags are pushed and squeezed against the positioning plate 13. Then, the two push plates 14 push the paper bags for a second time through their respective driving components, and the paper bags are located in the middle of the translation plate 12. The driving mechanism on the support platform 11 drives the translation plate 12 to move horizontally for a certain distance. At this time, the translation plate 12 arrives at the transfer station, and the external suction cup manipulator is used to grab only one paper bag at a time.

[0046] Among them, the driving mechanism belongs to the existing technology. As for how the driving mechanism drives the plate to move horizontally, reference can be made to the existing technology, such as a screw slider structure, a linear motor, a cylinder 36 drive, a chain drive, etc. In addition, the movement of the translation plate 12 can also be manual.

[0047] At the transfer station, the suction cup grabs the paper bag and moves upward. When the attached excess paper bag contacts the baffle 16, the second paper bag will be peeled off under the action of the baffle 16.

[0048] As an implementation of this embodiment, the material blocking assembly 15 includes:

[0049] A support frame 17, the support frame 17 comprises a top plate 18 and a bottom plate 19, the top plate 18 is mounted on the bottom plate 19 via a fixing rod 20, and the bottom plate 19 is mounted on the support platform 11;
