[0036] The bottom end of the support column 3 is welded to the frame 1; the middle of the bottom side of one end of the flap 4 is rotatably connected to the top of the support column 3 through the rotating shaft A301; the hydraulic cylinder body 5 is arranged in the frame 1, and the hydraulic cylinder body 5 is selected and used by the technical personnel in this profession according to the actual situation; wherein, the outer end of the cylinder body of the hydraulic cylinder body 5 is rotatably connected to the frame 1 through the rotating shaft B501, and the outer end of the piston rod of the hydraulic cylinder body 5 is rotatably connected to the bottom side of the flap 4 through the rotating shaft C502; wherein, a plurality of U-shaped frames 401 are fixedly provided on the bottom side of the flap 4, and a suction cup B402 is fixedly provided on the U-shaped frame 401, and the suction cup B402 is located in the opening on the flap 4.

[0037] The utility model has the advantage of being able to flip the flap 4 to be vertical after the packaging bag is opened by suction for packaging, by arranging the support column 3, the flap 4, the hydraulic cylinder body 5, the rotating shaft A301, the rotating shaft B501 and the rotating shaft C502, so that the packaged articles can be quickly and conveniently dropped onto the subsequent conveyor belt, thereby solving the problem that the articles need to be pushed onto the subsequent conveyor belt, and the pushing mechanism occupies a large lateral space due to the lateral pushing.

[0038] Specifically, the adsorption side of the suction cup B402 is aligned with the top side of the flap 4. After the top side of the flap 4 contacts the packaging bag, the adsorption side of the suction cup B402 contacts the packaging bag for adsorption.

[0039] Furthermore, a buffer structure 6 is arranged in the frame 1;

[0040] The buffer structure 6 includes a transverse plate 601, an extension plate 602 and a buffer spring piece 603; the transverse plate 601 is fixed on one side of the frame 1; the two extension plates 602 are respectively fixed on both sides of a groove 6011 opened on the top side of the transverse plate 601; the buffer spring piece 603 is arranged on the two extension plates 602, and the top side of the extension plate 602 is aligned with the bottom side of the groove 6011.

[0041] The utility model provides the horizontal plate 601, the groove 6011, the extension plate 602 and the buffer spring sheet 603, so that when the flap 4 is turned to the horizontal, the buffer spring sheet 603 is contacted to buffer the flap 4, so that the impact force is small when the flap 4 is turned to the horizontal.

[0042] Furthermore, the buffer spring piece 603 is designed with an arc-shaped structure, and the two ends of the buffer spring piece 603 are respectively fixed to the top sides of the two extension plates 602, and the arched end of the buffer spring piece 603 faces upward, and the arched end of the buffer spring piece 603 contacts and cooperates with the bottom side of the other end of the flap 4. When the flap 4 is flipped to a horizontal state, the arc-shaped buffer spring piece 603 contacts the flap 4 and will not hinder the flap 4.

[0043] Working principle: When using the device of the utility model, under the action of the hydraulic cylinder body 5, the flap 4 is flipped to the horizontal state, at which time the arc-shaped buffer spring 603 is squeezed and bent, and the packaging bag is taken out and moved to the top of the flap 4 through the suction cup A2 of the bag-taking structure of the frame 1. The bag-taking structure of the frame 1 moves downward under the action of the hydraulic mechanism until the packaging bag contacts the flap 4, and the suction cup B402 is connected to an external vacuum pump to vacuum and adsorb the packaging bag. The bag-taking structure of the frame 1 moves upward, and the suction cup A2 moves upward to open the packaging bag for packaging items, and then the suction cup A2 and the suction cup B402 are no longer adsorbed, and the suction cup A2 continues to move upward, and under the action of the hydraulic cylinder body 5, the flap 4 is flipped to the vertical state, and the packaged items fall onto the subsequent conveyor belt due to gravity.
