[0020] Implementation plan: During use, the paper tape passes through the rear side of the main reversing roller 29 and the front side of the two auxiliary reversing rollers 30. The two reversing baffles 31 limit the paper tape. When it is necessary to adjust the direction of the paper tape, loosen the clamping nut 28 and rotate the main reversing roller 29 to adjust the direction of the paper tape. By adjusting the distance between the two reversing baffles 31, the device can be used to feed paper tapes of different sizes. The tension and direction of the paper tape are controlled by the main reversing roller 29, the auxiliary reversing rollers 30 and the reversing baffles 31 to prevent the paper tape from becoming loose, overstretched, or deviating.

[0021] The bottom paper is then passed under the pressure plate 11, and the distance between the two guide plates 14 can be adjusted according to the width of the bottom paper. The pressure plate 11 and the guide plate 14 position and guide the paper tape, so as to accurately position the paper for the subsequent punch 8 to cut the bottom paper.

[0022] Then, by flipping the central shaft 38 upward through the handle 39, the groove 41 is flipped away from the perforation 40. At this time, the perforation 40 and the outer wall of the central shaft 38 are in contact with each other. The hanging plate 37 drives the pressure roller 32 to move upward, while the spring 35 is compressed. After the pressure roller 32 moves upward, the paper strip passes between the pressure roller 32 and the paper feeding drive roller 16. Then, the handle 39 is flipped downward, and the pressure roller 32 presses the paper strip tightly against the outside of the paper feeding drive roller 16. Then, the paper strip passes between the top plate 3 and the punching die 4.

[0023] The eccentric wheel of the drive component drives the connecting rod 9 to move up and down. The connecting rod 9 drives the punching die 4 to move upward. The punching die 6 first presses down the paper strip, and then the punching die 4 punches out a circular paper piece. Then the cam of the drive component drives the punch 8 to move upward. The circular paper piece is stretched and shaped in the punching cutter 42 to become the shape required for the bottom of the cup, and then sent into the main turntable cone die of the next process.
