The bag-sorting frame 511 is equipped with a horizontal driver 5111 that drives the bag-sorting base 512 to slide horizontally. An automatic bag-sorting and sealing device 5 is used to neatly arrange and seal the opening of the packaging bag. The automatic bag-sorting mechanism 51 neatly arranges and folds the opening of the packaging bag, and then the automatic sealing mechanism seals the arranged opening of the packaging bag, ensuring a neat and flat seal.

[0025] Now, in conjunction with the appendix Figure 7 A simplified explanation of the working principle of the automatic bag-sorting mechanism 51: First, the bag-sorting drive mechanism 516 adjusts the positions of the upper left support rod 5131, lower left support rod 5132, upper right support rod 5133, and lower right support rod 5134 so that they can extend into the packaging bag; Second, the horizontal driver 511 drives the bag-sorting base 512 to move towards the packaging bag, causing the upper left support rod 5131, lower left support rod 5132, upper right support rod 5133, and lower right support rod 5134 to extend into the packaging bag; Third, the bag-sorting drive mechanism 516 adjusts the upper left support rod 5131, lower left support rod 5132, upper right support rod 5133, and lower right support rod 5134... The positions of 5133 and the lower right support rod 5134 are designed to open the four corners of the packaging bag (the upper left support rod 5131, lower left support rod 5132, upper right support rod 5133, and lower right support rod 5134 are roughly arranged in a rectangular shape). Finally, the bag folding drive mechanism 519 drives the left inner folding rod 517 and the right inner folding rod 518 to fold the left and right sides of the packaging bag inward. At the same time, the upper left support rod 5131 and the lower left support rod 5132 retract each other, and the upper right support rod 5133 and the lower right support rod 5134 retract each other, thus completing the bag sorting process (arranging and folding the opening of the packaging bag neatly).

[0026] In this embodiment, the left inner folding rod 517 and the right inner folding rod 518 only need to move horizontally left and right. The bag base 512 is slidably connected to a first sliding seat 5121 and a second sliding seat 5122 in the horizontal direction.

The folding bag drive mechanism 519 is a first linkage motor mounted on the bag base 512 that drives the first linkage gear 51253 to rotate, thereby driving the left inner folding rod 517 and the right inner folding rod 518 to move synchronously in opposite directions or away from each other. With this design, only one power source (the first linkage motor) is needed to drive the left inner folding rod 517 and the right inner folding rod 518 to move synchronously in opposite directions.

[0027] In this embodiment, the upper left support rod 5131, lower left support rod 5132, upper right support rod 5133, and lower right support rod 5134 all need to move left, right, up, and down. Therefore, the bag-collecting base 512 is slidably connected with a third sliding seat 5123 and a fourth sliding seat 5124 in the horizontal direction.
