[0028] A cylinder 18 is bolted to the right side of the top of the shell 11, and a slide groove 19 is provided on the right side of the bottom of the inner cavity of the shell 11. A cutting blade 20 is slidably connected to the inner side of the slide groove 19, and the top of the cutting blade 20 is bolted to the telescopic end of the cylinder 18. When the paper sheet on the paper roll is close to being empty, the cylinder 18 is used as a driving source to push the cutting blade 20 to move horizontally, so as to separate the paper sheet from the paper roll and perform the roll changing operation.

[0029] A ventilation hole slot 21 is arranged on the left side of the negative pressure tube 13 so that the negative pressure tube 13 can extract the air on the surface of the conveying shaft tube 12 through the ventilation hole slot 21 .

[0030] Both sides of the front side of the rotating disk 4 are bolted with oblique strips 22, which serve as guide components for pulling out paper sheets from the paper roll to prevent the paper sheets from breaking due to pulling force.

[0033] Servo motors 25 are bolted to both sides of the front of the rotating disk 4, and the front of the flat press plate 9 is bolted to the output end of the servo motor 25. The servo motor 25 is used as a driving source to drive the flat press plate 9 to rotate.

[0034] Refer to the instruction manual Figures 1-5 Working principle: through the rotating disk 4, feeding roller 5, first auxiliary roller 6, contact plate 8, flat plate 9, connecting rod 10 and other components, during the use of the device, the feeding roller 5 is driven to rotate by the rotating disk 4, and after the unloaded feeding roller 5 is rotated to the bottom, the fully loaded feeding roller 5 waiting for discharging rotates to the top, at this time, the first stepper motor 23 is started, and drives the fully loaded feeding roller 5 to rotate, the paper sheet rotates and extends one end as the discharging side, and is pushed by the oblique bar 22 and the first auxiliary roller 6 and the second auxiliary roller 7, so that one end of the paper sheet moves to the inside of the contact plate 8 and the outside of the flat plate 9. At this time, the servo motor 25 is started, driving the flat plate 9 to rotate according to its axis, pushing one end of the paper sheet and the outer side of the flat plate 9 together to the contact plate 8, forming a limiting notch for discharging, and improving the speed of the cardboard processing device by cross-changing paper rolls and connecting the loading. The working efficiency is improved by using the components such as the conveying shaft tube 12, the negative pressure tube 13, the exhaust pipe 14, and the exhaust fan 15. During the use of the device, the exhaust fan 15 extracts the air in the negative pressure tube 13 through the exhaust pipe 14, and the negative pressure tube 13 generates negative pressure on the surface of the conveying shaft tube 12 through the ventilation hole groove 21. When one end of the paper sheet approaches the conveying shaft tube 12, the paper sheet will be attached to the surface of the conveying shaft tube 12 due to suction, and will be pushed to the right side of the shell 11 by the rotation of the conveying shaft tube 12. Since the negative pressure tube 13 can only apply negative pressure to the left half of the conveying shaft tube 12 through the ventilation hole groove 21, when the paper sheet rotates to the right half of the conveying shaft tube 12, the exhaust fan 15 is turned off, and the paper sheet will be separated from the conveying shaft tube 12 and will be continuously and stably transported by the conveyor belt 17. This process does not require manual intervention, which greatly improves the safety and production efficiency of the operation.
