[0036] During use, the pressing plate 50 abuts against the top of the bulk bag. The first handling power element 31 drives the first connecting rod 27 to move through the first connecting arm 28, thereby driving the first air pipe 21 to rotate. At the same time, the second handling power element 35 drives the second connecting rod 32 to move through the second connecting arm 33, thereby driving the second air pipe 22 to rotate synchronously in the opposite direction, so that the first cutting head 23 and the second cutting head 24 rotate synchronously in the opposite direction to realize clamping or releasing of the bulk bag; One end of the first air pipe 21 is connected to the air supply mechanism, and the other end is connected to the first cutting head 23. One end of the second air pipe 22 is connected to the air supply mechanism, and the other end is connected to the second cutting head 24, so that the first cutting head 23 and the second cutting head 24 blow air towards the bulk bag, reducing the residual amount of powder on the bulk bag; The air pump is connected through the air duct 70 to realize dust suction or back blowing.

[0037] In the automatic handling device 100 for the bulk bag of the present utility model, the first air pipe 21 and the second air pipe 22 rotate in the opposite direction, thereby driving the first cutting head 23 and the second cutting head 24 to rotate in the opposite direction to realize clamping or releasing of the bulk bag; One end of the first cutting head 23 is connected to the first air pipe 21, and the other end blows air towards the bulk bag. One end of the second cutting head 23 is connected to the second air pipe 22, and the other end blows air towards the bulk bag, thereby reducing the residual powder on the bulk bag.

For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0039] The above-described embodiments only represent several implementation manners of the present utility model. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
