The upper end of the inner folding edge 302 is a flat structure to ensure that the cup bottom 9 can be folded and connected to the cup body 8 smoothly. The side of the outer folding edge 301 facing the center of the base 1 is an arc-shaped structure. The outer folding edge 301 with an arc-shaped structure can realize limiting the cup body 8 during rotation to prevent the cup body 8 from deforming during rotation.

[0043] The operating steps of the folding bottom structure of the utility model are as follows:

[0044] First, the position of the folding piece 3 in the groove 2 is adjusted and fixed according to the diameter of the bottom 9 of the paper cup to be folded, and the external mold 7 is controlled to carry the cup body 8 and fall on the upper part of the base 1, and the bottom 9 of the paper cup falls on the upper part of the base 1.

[0045] Secondly, the rotating device connected to the structure is controlled to rotate, so that the base 1 rotates and drives the folding piece 3 to rotate. At this time, the folding piece 3 will fold and combine the cup body 8 and the paper cup bottom 9, and the bottom is flat.
