[0034] The present utility model provides a bag-opening packaging mechanism, as Figures 1 to 6As shown in the figure, it includes a frame 10. An open-bag movable frame 20 and a push-pull device are provided on the frame 10. The push-pull device is connected to the rear end of the open-bag movable frame 20 and can drive the open-bag movable frame 20 to linearly move forward and backward on the same plane. A pair of open-bag inserting knives 40 are suspended below the open-bag movable frame 20. The pair of open-bag inserting knives 40 are symmetrically arranged and can be controlled to move towards each other synchronously to close or move away from each other synchronously to separate. A first outstretched frame 50 is arranged on the frame 10. A suction cup 51 is provided on the first outstretched frame 50. The suction cup 51 is located in front of the open-bag inserting knives 40 and can be controlled to move up and down. A second outstretched frame 60 is arranged on the frame 10. A limiting head 61 is provided on the second outstretched frame 60. The limiting head 61 is located in front of the suction cup 51 and can be controlled to move up and down.

[0035] During use, the packaging bag is located below the suction cup 51 and the limiting head (which can be placed manually or delivered there by a conveying device). At this time, the front end of the packaging bag with an opening faces the direction of the open-bag movable frame 20, and its closed tail end is away from the open-bag movable frame 20. Then, the limiting head is controlled to press down on the tail end of the packaging bag. After the tail end of the packaging bag is limited, the suction cup 51 is controlled to press down on the front end of the packaging bag and adsorb on the packaging bag. Then, the suction cup 51 is lifted to lift the upper layer of the packaging bag, so that the opening of the packaging bag is opened. Then, the open-bag movable frame 20 moves forward. At this time, the pair of open-bag inserting knives 40 are in a closed state. The open-bag movable frame 20 moves forward with the pair of open-bag inserting knives 40 inserted into the opened opening of the packaging bag and located in the middle of the opening. Then, the pair of open-bag inserting knives 40 are controlled to move apart synchronously. In this way, both sides of the opening of the packaging bag are synchronously expanded. Thus, the process of opening the packaging bag is completed. The bagging mechanism of the next process can then send items into the packaging bag. After bagging is completed, the pair of open-bag inserting knives 40 are controlled to close, and then the open-bag movable frame 20 withdraws backward with the pair of open-bag inserting knives 40. Thus, the bagging process of the packaging bag is completed.

[0036] In the present utility model, the open-bag movable frame 20 drives a pair of open-bag inserting knives 40 to be inserted forward into the opened packaging bag or withdrawn from the packaging bag after bagging is completed. The pair of open-bag inserting knives 40 can move towards both sides of the packaging bag synchronously after being inserted into the packaging bag to expand the opening of the packaging bag, ensuring that the opening of the packaging bag is expanded from the middle to both sides, with a uniform opening and no collapse, guaranteeing the opening effect. The pair of open-bag inserting knives 40 will also close after bagging is completed, ensuring a smooth withdrawal process, with a reasonable structure and strong practicability.

[0037] Further, in some embodiments of the present utility model application, such as Figures 4 to 6As shown, the pushing and pulling device is a pushing and pulling cylinder 30. A fixing frame 31 is provided at the lower rear of the frame 10. The pushing and pulling cylinder 30 is fixed to the fixing frame 31, and the cylinder rod of the pushing and pulling cylinder 30 extends forward and is connected to the rear end of the bag-opening movable frame 20 to drive the bag-opening movable frame 20 to move back and forth. The top surface of the bag-opening movable frame 20 is slidably connected to the bottom surface of the frame 10, and the pushing and pulling cylinder 30 can control the bag-opening movable frame 20 to slide on the bottom surface of the frame 10 through its cylinder rod to extend forward or retreat.

[0038] Further, in some embodiments of the present utility model application, such as Figures 4 to 6 As shown, a pair of bag-opening cutting knives 40 are slidably connected below the bag-opening movable frame 20. A rack plate 70 is connected between the pair of bag-opening cutting knives 40. A driving motor 80 and a linkage shaft 90 are connected to the bag-opening movable frame 20. The driving motor 80 is linked with the linkage shaft 90. A linkage gear 91 is provided at the lower end of the linkage shaft 90. The linkage gear 91 meshes with the rack plate 70. The driving motor 80 can drive a pair of bag-opening cutting knives 40 to move synchronously towards each other or separate synchronously under control. When in use, the driving motor 80 drives the linkage shaft 90 to rotate. After the linkage shaft 90 rotates, the linkage gear 91 at its lower end rotates synchronously, thus driving the rack plate 70 engaged with it to move. While the rack plate 70 is moving, it drives a pair of bag-opening cutting knives 40 connected to it to close or separate to both sides synchronously. In the embodiment, the closing and separating of a pair of bag-opening cutting knives 4 are controlled by the tooth level of the rack plate, so only the tooth level stroke of the rack plate 70 needs to be controlled according to the opening size of the packaging bag, thus avoiding the situation that the opening of the packaging bag fails to be fully opened or is damaged due to excessive opening force.

[0039] Further, in some embodiments of the present utility model application, such as Figures 4 to 6 0As shown, a first cylinder 52 is provided on the first outrigger 50.
