A power source is arranged on the rack to drive the rotating shaft to rotate and drive the mounting seat to enter the next process. The upper end of the connecting rod is fixedly provided with a swing lever for balancing the weight of the mounting seat. The swing lever and the connecting rod are arranged on the two sides of the rotating shaft respectively.

[0004] Preferably, the swing lever is arranged obliquely on the upper end of the connecting rod, and the swing lever extends upward and is inclined to the feeding direction of the mounting seat.

[0005] Preferably, the included angle a between the length direction of the swing lever and the length direction of the connecting rod is 5-25 degrees, and the included angle b between the swing direction of the connecting rod and the vertical direction is the same as the included angle a between the length direction of the swing lever and the length direction of the connecting rod.

[0006] Preferably, the power source is a motor, which drives the rotating shaft to rotate through a rotating block. A first rotating rod is fixedly arranged on the rotating shaft. The first rotating rod and the rotating block are connected through a second rotating rod.

[0007] Preferably, the two ends of the rotating shaft are rotatably arranged on the rack through rotating seats.

A bag-feeding component for feeding the bag in the first bag clamping station into the second bag clamping station is provided between the first bag clamping station and the second bag clamping station. The first bag clamping station is provided with a bag opening mechanism for opening the bag opening.

[0009] Compared with the prior art, this utility model uses a power source to drive the mounting base to rotate around the shaft and then feed the bag into the next process. By setting a counterweight on the upper end of the connecting rod, the weight on both sides of the shaft is balanced during the operation, ensuring stability when the connecting rod swings. The mounting base feeds the bag into the next process more stably. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0017] like Figures 1-5As shown, a conveying swing arm assembly includes a frame 1 and two oppositely arranged mounting seats 2 for fixing bags and feeding them into the next process. The mounting seats 2 are movably mounted on the frame 1 at both ends via connecting rods 3. The upper ends of the two connecting rods 3 on the same side of the two mounting seats 2 are connected by a rotating shaft 4 to achieve synchronous rotation of the two mounting seats 2. The two ends of the rotating shaft 4 are rotatably mounted on the frame 1 via rotating seats 10. A power source 5 is provided on the frame 1 to drive the rotating shaft 4 to rotate and thus rotate the mounting seats 2 to enter the next process. A swing arm 6 is fixedly mounted on the upper end of the connecting rod 3 to balance the weight of the mounting seats 2. The swing arm 6 and the connecting rod 3 are located on opposite sides of the rotating shaft 4. The swing arm 6 is inclined at the upper end of the connecting rod 3, extending upwards and inclined towards the feeding direction of the mounting seats 2. The angle α between the length direction of the swing arm 6 and the length direction of the connecting rod 3 is 15 degrees, and the swing angle b of the connecting rod 3 during feeding is 15 degrees. After the power source 5 drives the mounting base 2 to rotate around the shaft 4, the bag is sent into the next process. By setting a counterweight on the upper end of the connecting rod 3, the weight on both sides of the shaft 4 is balanced during the operation. The inclined swing rod 6 makes the connecting rod 3 tilted, and when the mounting base 2 sends the bag into the next process, the swing rod 6 is spherical, the force is balanced, and the center of gravity is more stable and balanced. The swing rod 6 has a good balancing effect on the connecting rod 3, ensuring the stability after the connecting rod 3 tilts. The mounting base 2 is more stable when sending the bag into the next process.

[0018] The power source 5 is an electric motor, which drives the rotating shaft 4 to rotate via a rotating block 7. A first rotating rod 8 is fixedly mounted on the rotating shaft 4, and the first rotating rod 8 is connected to the rotating block 7 via a second rotating rod 9. The two ends of the second rotating rod 9 are respectively rotatably mounted on the first rotating rod 8 and the rotating block 7. The synchronous movement of the two mounting bases 2 can be achieved by the motor driving the rotation of one of the rotating shafts 4.

[0019] The mounting base 2 is sequentially equipped with a first bag-clamping station 14 and a second bag-clamping station 11 for clamping bags. A bag-feeding assembly 12 for feeding bags from the first bag-clamping station 14 into the second bag-clamping station 11 is provided between the first bag-clamping station 14 and the second bag-clamping station 11. The first bag-clamping station 14 is equipped with a bag-opening mechanism 13 for opening the bag opening. The bag is fed into the first bag-clamping station 14 from the previous process for clamping and fixing. The bag opening mechanism 13 opens the bag opening in the first bag-clamping station 14, and the bag-feeding assembly 12 feeds the opened bag from the first bag-clamping station 14 to the second bag-clamping station 11 for clamping and fixing. Then, the swinging mounting base 2 feeds the opened bag into the next process, completing the bag conveying.

[0020] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
