The horizontal area is an area where two side lines parallel to the ground are located, wherein the horizontal area located above is an upper horizontal area, and the horizontal area located below is a lower horizontal area; the arc area is the area where the two edges are located coaxially with the rotating wheel 31.

Referring to fig. 1 and 2, in the moving process of the push plate 2, when the push plate 2 is located in the lower horizontal region of the annular track, the push plate 2 moves forward (forward movement in this embodiment refers to movement of pushing the small-package paper towel to a direction approaching to the downward moving process equipment), and the push plate 2 is attached to the side face of the small Bao Zhijin, so that the small-package paper towel can be pushed to move, and separation between the small-package paper towel and the conveying belt is achieved.
