[0048] The arc compression mechanism 4 also includes: a limit assembly, which is installed on the right side of the cabinet 1. The limit assembly includes: a special-shaped frame 46, a connecting plate 47, an arc-shaped guide plate 48, a second cylinder 49 and a C-shaped plate 410.

The C-shaped plate 410 is fixedly installed on the output end of the second cylinder 49, and the C-shaped plate 410 is located between the special-shaped frame 46 and the arc-shaped guide plate 48.

[0049] The push plate 45 moves to the right, pushing the cut segmented filter paper to move to the right. The cut segmented filter paper moves to the right, passes through the connecting plate 47 and enters the position of the arc guide plate 48. The segmented filter paper is restricted by the special-shaped frame 46 and the arc guide plate 48 to form an arc-shaped compression state.

The inner and outer side walls of the first inner frame 411 and the first outer frame 412 are both smooth. The compressed segmented filter paper automatically unfolds after entering and fills between the first inner frame 411 and the first outer frame 412. The pneumatic rounding mechanism 5 assists the segmented filter paper to further form a circle. Then the output end of the third cylinder 416 shortens and drives the arc-shaped sliding plate 415 to move forward. The arc-shaped sliding plate 415 moves forward and drives the rounded filter paper to move forward and push out, completing the folding assembly of the filter paper.
