7. The special paper roll conveying and packaging system according to claim 6, characterized in that: The inner head placement device further comprises an inner head placement device (12) for placing the inner head on the inner head clamp (13) into the special paper roll (20); the inner head placement device (12) comprises a connecting seat (12.1), a first driving member (12.2), a clamping head (12.3), a mounting plate (12.4), a displacement sliding member, and a second driving member (12.5); The clamping head (12.3) is used to clamp the inner head; One end of the first driving member (12.2) is rotatably connected to the mounting plate (12.4), and the other end of the first driving member (12.2) is connected to the clamping head (12.3) for driving the clamping head (12.3) to rotate, thereby transporting the inner seal from the inner seal clamp (13) into the specialty paper roll (20); The displacement sliding member is arranged between the connecting seat (12.1) and the mounting plate (12.4); the second driving member (12.5) is fixedly mounted on the mounting plate (12.4); the movable end of the second driving member (12.5) is connected to one relatively sliding end of the displacement sliding member; and the mounting plate (12.4) is connected to the other relatively sliding end of the displacement sliding member, so that the mounting plate (12.4) is driven by the second driving member (12.5) to perform horizontal displacement relative to the connecting seat (12.1).

8. The special paper roll conveying and packaging system according to claim 7, characterized in that: The whole-web packaging device comprises a paper placing mechanism (14), a paper feeding mechanism (17) and a folding mechanism (18) which are arranged in sequence; A kraft paper roll for packaging a special paper roll (20) in its entirety is rotatably mounted on a paper placing mechanism (14) and is transported to a paper feeding mechanism (17) via the paper placing mechanism (14). The paper feeding mechanism (17) cuts the special paper roll (20) according to the size and packaging requirements and packages the special paper roll (20) in its entirety. The folding mechanism (18) is used to perform folding operations on the special paper roll (20).

9. The special paper roll conveying and packaging system according to claim 7 or 8, characterized in that: Also included is a labeling device (1); The labeling device (1) is arranged near the first chain conveyor (2) and is used to perform a labeling operation on the special paper roll (20) after being tape-wrapped by the tape-wrapping device (5).

10. The special paper roll conveying and packaging system according to claim 9, characterized in that: Also includes a hydraulic system (11); The hydraulic system (11) is used to provide hydraulic energy to the paper kicker (7) and the buffer (6) and to perform hydraulic control.
