[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] like Figure 1-7 As shown, a soft bag folding machine includes a first conveyor line 1, a folding conveyor line 2, and a belt conveyor 3 arranged sequentially along the processing steps. A folding conveyor line 4 for conveying folded products is provided on one side of the folding conveyor line 2. A frame 5 is mounted above the folding conveyor line 2. Within the frame 5 are a sorting power hand 6 for adjusting the position of the soft bag bundles 29 on the first conveyor line 1 and placing them onto the folding conveyor line 2, and a folding power hand 7 for folding the soft bag bundles 29 on the folding conveyor line 2 and continuing to move them along the folding conveyor line 2, or for grabbing the soft bag bundles 29 and folding them along the folding conveyor line 4. A detection device 8 is provided on the folding conveyor line 2 for detecting the state of the soft bag bundles. The detection device 8 detects the packaging state of the soft bag bundles 29. A properly packaged soft bag bundle 29 is in a vacuum-sealed, solid state. When a leaking, bulging soft bag bundle 29 is detected, the subsequent folding power hand 7 will not grab the malformed soft bag bundle 29. It can fold the soft bag into half or three parts and then convey it according to the actual processing needs. It has a simple structure and is easy to operate.

[0023] The folding conveyor line 2 is equipped with two rotating conveyor belts 9, which can be in various forms such as plate chains or belt conveyors. Placement stations 10 for soft-bag bundles are provided on each conveyor belt 9, with station plates 11 positioned between adjacent placement stations 10. A fixed rod 12 extending above the folding conveyor line 2 is fixedly installed on one side of the folding conveyor line 2. A pressing plate 13 extending downwards and pressing against the soft-bag bundle 29 is fixedly installed on the fixed rod 12. The pressing plate 13 is located above the soft-bag bundle on the side away from the folding conveyor line 4, and is located on both sides of the station plates 11 on the conveyor belt 9. A baffle rod 14 is provided on the folding conveyor line 2 to block the soft-bag bundle. The baffle rod 14 is telescopically mounted on the folding conveyor line. When folding the soft-bag bundle, the conveyor belt 9 stops moving, and the baffle rod 14 limits the movement of the soft-bag bundle, ensuring that the soft-bag bundle remains at the baffle rod 14 during folding. The folding conveyor line 2 is equipped with side plates 31 for restricting the movement of the soft bag bundles. These side plates 31 are located on both sides of the soft bag bundles' movement path on the folding conveyor line 2 to prevent angular deviation or displacement of the soft bag bundles during stopping. The soft bag bundles are eight-packs. The sorting power hand 6 is equipped with eight suction cups for picking up the soft bag bundles 29, and the folding power hand 7 is equipped with four suction cups for picking up the soft bag bundles. As the soft bag bundles 29 move with the conveyor belt 9 to below the pressure plate 13, some suction cups on the folding power hand 7 grab the end of the soft bag bundle away from the pressure plate 13, leaving some ungrabbed soft bags between the pressure plate 13 and the folding power hand 7. The folding power hand 7 moves upward to the pressure plate 13 and places the grabbed soft bag bundles on top of the pressure plate 13, completing the three-fold folding of the soft bag bundles 29. The folded soft bag bundles 29 continue to move with the conveyor belt 9.

[0024] The folding conveyor line 4 is equipped with a folding device 15 for folding the soft bag package 29. The folding device 15 includes a base 16 fixedly mounted on the folding conveyor line 4. The base 16 has an opening 17 located above the folding conveyor line 4. The base 16 is fixedly mounted with two opposing side baffles 18 and a lower baffle 19 located below the side baffles 18. The lower baffle 19 can move away from the other lower baffle 19 under the drive of the first power source 30. The lower baffle 19 and the side baffles 18 are both located above the opening 17. A front baffle 20 is fixedly mounted between the two side baffles 18. The front baffle 20 is located on the side of the base 16 away from the folding conveyor line 2. A guide plate 21 extending to the folding conveyor line 2 is fixedly mounted on the side of the base 16 facing the folding conveyor line 2. The end of the folding conveyor line 4 away from the folding device 15 is movably equipped with a pusher plate 22 for pushing the folded soft package into the next process. The folding conveyor line 4 is equipped with a second power source 23 for driving the pusher plate 22 to move laterally perpendicular to the folding conveyor line 4, and the second power source 23 is equipped with a third power source 24 for driving the pusher plate 22 to enter the folding conveyor line 4 vertically. The folding power arm 7 grasps the soft bag bundle 29 at the end away from the guide plate 21. During the upward movement, the soft bag bundle 29 on the side closer to the guide plate 21 gradually becomes vertical under the action of gravity. The folding power arm 7 moves the grasped part of the soft bag bundle 29 upward to the base 16. The vertical part of the soft bag bundle 29 is folded and moved below the part of the soft bag bundle 29 grasped by the folding power arm 7 under the obstruction of the guide plate 21, and is placed above the lower baffle 19 in a folded state. After the folding is completed, the lower baffle 19 is driven to move, so that the folded soft bag bundle enters the folding conveyor line 4 through the opening 17 for conveying. When it moves to the end of the folding conveyor line 4 away from the base 16, it enters the next process through the push plate 22.

[0025] The conveyor belt 3 is equipped with a continuously rolling belt 25. Slide seats 26 are movably mounted on both sides of the conveyor belt 3. A sliding rod 27 is fixedly mounted on each slide seat 26 to adjust the length of the belt 25 at its upper end. A fourth power source 28 is fixedly mounted on one side of the slide seat 26 to adjust the position of the sliding rod 27. Adjusting the position of the sliding rod 27 via the fourth power source 28 adjusts the length of the belt 25 at its upper end. Upon detecting an unclamped soft bag bundle 29, the conveyor belt 3 is retracted, causing the unclamped soft bag bundle 29 to fall below the conveyor belt 3, preventing it from entering the next process.

[0026] 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.
