It should be noted that, when the vacuum suction plate assembly 73 is loaded with the package bag, the conveyor motor 835 is started to rotate the conveyor roller 834, and the package bag is conveyed to the nip between the vacuum suction plate assemblies 73 by the friction between the rotation of the conveyor roller 834 and the package bag, and here, it is emphasized that, in this case, the suction force does not exist in the nip of the vacuum suction plate assemblies 73, and therefore, the input of the package bag is not hindered, and the input package bag has an open end facing outward.

To be more specific, a side wall of the storage box 831 may be opened for loading the packing bags, and the material receiving plate 832 makes the packing bags on the top of the storage box 831 contact with the conveying roller 834 via the lifting spring 833 disposed below the material receiving plate.

It should be noted that the suction force of the vacuum suction plate 731 in the present invention is derived from the vacuum suction force of the vacuum shaft 71, and the vacuum pump 711 forms a suction force on the side wall of the vacuum suction plate 731 through the vacuum shaft 71, but it should be noted that, in the process of rotating the turntable 72, the vacuum suction plate 731 rotates, and the connection ring 713 connected to the vacuum suction plate 731 through the bellows also rotates, so that when the bellows rotates to a position where the communication port 712 is not opened, the corresponding vacuum suction plate 731 loses the suction force, the sucked package bag drops, and the part where the communication port 712 is not opened covers the lower part of the turntable 72.

the compression spring 753 is sleeved on the polished rod on the locking block 752 and is arranged between the locking block 752 and the mounting seat 751 in an abutting mode.

It should be noted that the locking assembly 75 locks the driving gear 744, so that the driving gear 744 cannot rotate freely, which interferes with the closing and opening of the vacuum suction plate 731, and only when the driving gear 744 is acted by an external force, the locking block 752 lifts up by the elastic force of the compression spring 753, which can rotate freely.
