The implementation principle of the invention is as follows: after the first conveying mechanism 2 conveys the packaging bag completely between the two clamping frames 42, the suction part 44 sucks the bag mouth of the packaging bag, the moving mechanism 5 drives the swing arm 55 to rotate, and the movable rod 436 is inserted through the opening of the first guide rail section 451. When the swing arm 55 continues to rotate towards the position close to the second conveying mechanism 3, due to the limitation of the second guide rail section 452 and the third guide rail section 453, the movable rod 436 is gradually pulled away towards the side far away from the mounting frame 41 until the swing arm 55 rotates 90 degrees, when the length direction of the swing arm 55 is the vertical direction of the frame 1, the movable rod 436 is farthest from the mounting frame 41, the sliding frame 431 is pulled to slide along the mounting frame 41, the guide post 434 moves into the second horizontal groove section 4333, and the connecting rod 422 pulls the first plate 423 and the second plate 424 to be more stable when folded due to the rolling fit of the elastic plate 427 and the limiting wheels. At this time, the opening of the packaging bag is opened, the frame 1 can be provided with a filling mechanism, the material conveying opening of the filling mechanism is opposite to the opening of the packaging bag, after the packaging bag is filled with products, the adsorbing piece 44 loosens the adsorption to the opening of the packaging bag, and the packaging bag falls onto the second conveying mechanism 3 under the action of gravity and is conveyed to a corresponding position through the second conveying mechanism 3.
