It can also be understood that, taking the center of the first paper feeding assembly 21 in the front-back direction as a reference, the first through holes 2322 in multiple rows are arranged at equal intervals from inside to outside, and the aperture of each row of first through holes 2322 is larger than that of the adjacent first through holes 2322 in the inner row. With the structure, suction forces with different sizes can be obtained by adjusting the distance between the front and back spaces of the two guide blocks 232 of the two first paper separation assemblies 23; once the paper feeding device 20 conveys paper sheets with different thicknesses or different weights, the guiding block 232 can be adapted to different paper sheets for use by adjusting the position thereof, and the universality is good.

Meanwhile, the main frame 10 is provided with a CCD vision detecting device 11, the CCD vision detecting device 11 is located between the first paper feeding assembly 21 and the second paper feeding assembly 22, the CCD vision detecting device 11 is used for capturing a movement track of the first paper separating assembly 23 guiding the paper to enter the second paper feeding assembly 22, and feeding back the captured image to a control panel of the high-speed intelligent folding machine, so that an operator can obtain the movement track of the paper, and adjust the height, angle, front-rear position and air suction size of the guiding block 232.
In the traditional technology, paper is sucked by a sucking disc to be separated, and because the paper has certain air permeability, if the sucking disc is adopted to suck the paper to be separated, the situation that a plurality of stacked papers are sucked all at once, namely the situation of paper connection, is easy to occur; in the embodiment of the present application, by changing the position of the first through hole 2322, different suction forces are realized, and it is preferable that the first through hole 2322 can provide a suction force to make the paper float upward, but not completely suck the paper; this allows the topmost sheet to be continuously guided to the second sheet feed assembly 22 during the continuous feeding of the sheets. Meanwhile, the guide blocks 232 are arranged at the front side and the rear side of the first paper feeding assembly 21 to provide suction to the two sides of the paper to realize the guiding operation; the effect of providing suction to the two sides of the paper is that if two overlapped papers exist, the two sides of the topmost paper are sucked firstly, and air is supplemented between the two papers, so that the vacuum degree between the two papers is reduced, the paper separating operation is reliable, and the paper connecting condition is not easy to occur.
