And a Y-axis driving mechanism for driving the two Y-axis folding knives 3 to open or reset along the Y-axis direction; the driving component of the Y-axis driving mechanism is preferably a motor 31.

[0021] The two X-axis folding knives 2 are relatively arranged at both ends of the X-axis axis of the folding knife seat 1, and the two Y-axis folding knives 3 are relatively arranged on the Y-axis axis of the folding knife seat 1; when the two Y-axis folding knives 3 are relatively opened, the folding knife group is arranged in a rectangular shape.

[0022] like Figure 2 As shown, the X-axis folding knife 2 adjusting slots 11 are symmetrically arranged at both ends of the X-axis axis of the folding knife seat 1, and the X-axis folding knife 2 is arranged in the adjusting slots 11. The setting of the adjusting slots 11 is used to adjust the width between the two X-axis folding knives 2 according to the width of the product bag opening.

As mentioned above, the driving component is preferably a motor 31, and the motor 31 drives the gear shaft 32 to rotate; a rack 33 is arranged on the top of each Y-axis folding knife 3, and the tooth surfaces of the racks 33 of the two Y-axis folding knives 3 are opposite and mesh with the gear shaft 32. The motor 31 drives the gear shaft 32 to rotate, driving the two racks 33 to move in opposite directions, thereby driving the two Y-axis folding knives 3 to move synchronously toward or away from each other, so as to achieve the synchronous closing or opening of the two Y-axis folding knives 3.

[0024] Two Y-axis folding knife slide rails 12 are set at both ends of the X-axis axis of the folding knife seat 1, and the Y-axis folding knife 3 is slidably connected to the folding knife slide rails 12; the sliding connection can be that the Y-axis folding knife 3 is provided with a slide rail seat, and then connected to the slide rail 12 through the slide rail seat to realize the sliding of the Y-axis folding knife 3 on the slide rail 12; it can also be that the rack 33 is connected to the slide rail 12, and the rotation of the gear shaft 32 drives the rack 33 to move, thereby driving the movement of the Y-axis folding knife 3 connected thereto; of course, it can also be that the rack 33 is provided with a slide rail seat, and the slide rail seat is connected to the slide rail 12.
