[0043] This application sets up a lifting component so that merchants can adjust the height of the edge banding machine 6 within a certain range as needed, and change the distance between the edge banding machine 6 and the conveying component 2, so that it is suitable for edge sealing of commodity packaging bags of various heights and is practical.

[0044] Figure 3 to Figure 4 A second embodiment is shown, and its main difference from the first embodiment is that the flipping assembly includes a second motor 10 fixed to the top of the support frame 5, the inner wall of the support frame 5 is rotatably connected to a rotating shaft 11, a worm gear 12 is fixed to the middle of the rotating shaft 11, the inner wall of the support frame 5 is rotatably connected to a worm 13, the worm gear 12 is meshingly connected to the worm 13, and the top of the worm 13 passes through the support frame 5 and is fixed to the output end of the second motor 10.
