In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-6 shown, a bag-supporting mechanism for a bagging device proposed by the present utility model includes a fixing plate 1, a bag-supporting plate 2, and a bag-supporting mechanism 3. There are two groups of fixing plates 1 symmetrically arranged. At both ends of the fixing plate 1, a pushing cylinder 4 is fixedly connected. The bag-supporting mechanisms 3 are respectively fixed on the fixing plates 1 on both sides. The bag-supporting plate 2 is arranged on the bag-supporting mechanism 3. A moving sleeve block 5 is arranged on the bag-supporting mechanism 3. A detachable connection structure 6 is arranged between the bag-supporting plate 2 and the moving sleeve block 5. The detachable connection structure 6 includes a clamping plate 7, a clamping groove 8, and a first fixing rod 9. The clamping groove 8 is arranged at the bottom of the bag-supporting plate 2. The clamping plate 7 is clamped in the clamping groove 8. One end of the clamping plate 7 away from the clamping groove 8 is fixed with a movable end plate 14. The first fixing rod 9 passes through the movable end plate 14 and is fixed on the outer side wall of the moving sleeve block 5. One end of the first fixing rod 9 away from the moving sleeve block 5 is fixed with a connecting end plate 11. Springs 12 are fixedly connected to the outer side walls of the movable end plate 14 and the connecting end plate 11. Driving the movable end plate 14 to move drives the clamping plate 7 to move, and moving the clamping plate 7 out of the clamping groove 8, so as to take out the bag-supporting plate 2, which is convenient for disassembly. An installation groove 13 is arranged under the top wall of the moving sleeve block 5. The outer side wall of the bag-supporting plate 2 is closely attached to the inner wall of the installation groove 13 to initially limit the bag-supporting plate 2. The bottom walls of the clamping groove 8, the clamping plate 7, and the top walls of the installation groove 13 and the moving sleeve block 5 are on the same horizontal plane.

[0023] As Figure 4 、 6As shown in the figure, a second fixing rod 10 parallel to the first fixing rod 9 is fixed on the outer side wall of the connecting end plate 11 close to the spring 12. The second fixing rod 10 penetrates through the movable end plate 14 and exposes the outer side wall of the movable end plate 14, and the second fixing rod 10 has the same length as the first fixing rod 9, further increasing the stability and support strength of the movable end plate 14.

[0024] As Figure 1 , 2 shown in the figure, the bag-supporting mechanism 3 includes an embedded groove 15, a bidirectional lead screw 16 and a driving motor 17. The embedded groove 15 is arranged in the fixing plate 1. The driving motor 17 is fixed on the outer side wall of the fixing plate 1 close to one end of the embedded groove 15. One end of the bidirectional lead screw 16 is rotatably arranged on the inner side wall of the embedded groove 15, and the other end of the bidirectional lead screw 16 is arranged on the driving motor 17. The moving sleeve blocks 5 are symmetrically and threadedly sleeved on the bidirectional lead screw 16 and slide closely against the inner wall and the top wall of the embedded groove 15. The driving motor 17 drives the bidirectional lead screw 16 to rotate, thereby driving the moving sleeve blocks to move away from each other, and thus driving the bag-supporting plates 2 to move away from each other to open the packaging bag.

[0025] As Figure 1 shown in the figure, a connecting plate 18 and a socket plate 19 are respectively fixed on the outer side walls of the two fixing plates 1. The free end of the connecting plate 18 slides in the free end of the socket plate 19, increasing the stability of the connection between the fixing plates 1. An installation plate 20 is fixed under the bottom wall of one fixing plate 1, and an installation hole 21 is arranged on the installation plate 20, facilitating the installation and fixation of the bag-supporting mechanism 3.

[0026] During specific use, when the bag-supporting mechanism 3 is in use, the bag-supporting plates 2 are placed inside the opening of the packaging bag. The pushing cylinder 4 pushes the fixing plates 1 to both sides. At the same time, the driving motor 17 drives the bidirectional lead screw 16 to rotate, thereby driving the moving sleeve blocks 5 to move away from each other, and thus driving the bag-supporting plates 2 to move away from each other to open the packaging bag. When it is necessary to replace the bag-supporting plates 2, the movable end plate 14 is pushed to drive the clamping plate 7 to move, and the clamping plate 7 is moved out of the clamping groove 8, thereby taking out the bag-supporting plates 2. When installing the bag-supporting plates 2, first push the movable end plate 14 to one side to drive the clamping plate 7 to move. The movable end plate 14 moves relative to the first fixing rod 9 and the second fixing rod 10, and the spring 12 is compressed. The clamping plate 7 is moved to one side of the moving sleeve plate 5. The bottom of the bag-supporting plate 2 is placed in the installation groove 13 for preliminary positioning of the bag-supporting plate 2. The movable end plate 14 is released, and the clamping plate 7 is snapped into the clamping groove 8 under the action of the self-restoring force of the spring 12, thereby limiting and fixing the bag-supporting plate 2, facilitating the installation and disassembly of the bag-supporting plate 2.

[0027] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
