A guide assembly 8 is provided between the second baffle plate 4.2 and the third baffle plate 4.3. The guide assembly 8 comprises a frame-type bracket 8.1, which is fixed above the carton conveying roller 4 through a vertical bracket 8.2. A flexible guide blade 8.3 inclined downward is provided on the inner side of the frame-type bracket 8.1. A slide bar for the frame-type bracket 8.1 to slide is provided on the vertical bracket 8.2. A pushing cylinder 8.4 for pushing the frame-type bracket 8.1 to move up and down is provided on the carton conveying roller 4.

During operation, the carton moves from the input end to the output end on the carton conveyor roller 4. When the carton completely passes through the No. 1 baffle 4.1, the No. 1 baffle 4.1 extends to prevent the subsequent carton from entering the working area. Then the No. 3 baffle 4.3 extends to make the carton stay in the working area and cannot move forward. At the same time, the No. 2 baffle 4.2 extends to cooperate with the No. 3 baffle 4.3 to fix the carton one after the other. At this time, the push cylinder 8.4 retreats, driving the flexible guide blade 8.3 on it to enter the box opening, playing a guiding role in the subsequent packing process. It is convenient for packing; the liquid bag is driven by the liquid bag conveying roller 2 and finally falls on the grab bar 3.5 of the liquid bag grabber 3. Then, driven by the vertical ring chain group 6.3, the liquid bag grabber 3 moves upward as a whole, so that the liquid bag grabber 3 is completely higher than the carton. Then, driven by the horizontal ring chain group 7.1, it moves to the top of the carton, and then the grabber cylinder 3.6 extends out, the straight rack 3.7 rotates with the fan-shaped rack 3.9, and the fan-shaped rack 3.9 drives the grabber 3.3 to rotate. The grabber 3.3 is vertical, and the liquid bag is placed into the carton along the flexible guide blade 8.3. After the packing action is finished, the vertical ring chain group 6.3 drives the gripper device to move upward, and then moves to the top of the output end of the liquid bag conveyor roller 2 under the horizontal ring chain group 7.1, and then moves downward under the drive of the vertical ring chain group 6.3. While moving downward, the gripper cylinder 3.6 retracts, the spur rack 3.7 rotates with the fan-shaped rack 3.9, and the fan-shaped rack 3.9 drives the gripper 3.3 to rotate. The gripper 3.3 is horizontal and ready to grab the next liquid bag. At the same time, the cylinder 8.4 is pushed out so that the flexible guide blade 8.3 will not interfere with the operation of the carton. The second baffle 4.2 and the third baffle 4.3 retreat, so that the carton can leave the working area smoothly. When the carton completely leaves the working area, the third baffle 4.3 is pushed out, the second baffle 4.2 remains in the retracted state, and the first baffle 4.1 retreats. The next carton begins to enter the working area, and the automatic packing machine starts to work in a cycle.

The described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
