[0042] The magnetic connection assembly includes a ferrous support 30 and an electromagnetic socket 31. The ferrous support 30 is fixedly connected to the plurality of adjustment frames 18. The electromagnetic socket 31 is arranged on the output end of the second electric cylinder 24. The electromagnetic socket 31 is magnetically connected to the ferrous support 30. After the second electric cylinder 24 moves to the specified position, the second electric cylinder 24 is started to drive the electromagnetic socket 31 to move, so that the electromagnetic socket 31 moves into the corresponding ferrous support 30. The electromagnetic socket 31 is powered to generate magnetism and is magnetically connected to the ferrous support 30. When the output end of the second electric cylinder 24 continues to move, the corresponding adjustment frame 18 is driven to move in the push slide groove, so that the sliding body 23 slides on the sliding groove frame 22, and the second electric cylinder 24 can drive the adjustment frame 18 to reset.

[0044] The working principle of the web-fed full-rotary printing press is as follows: when it is necessary to perform web printing, the web to be printed is first mounted on the unwinding device 2, and then the first drive motor 10 is started to drive the transmission screw 9 to rotate, driving the threaded seat 11 to slide in the movable frame 8, so that the threaded seat 11 drives the sliding member 12 and the winding device 6 to move in the direction of the unwinding device 2. After the unwinding device 2 moves to one side of the inkjet printing device 3, one end of the web wound on the unwinding device 2 is pulled and fixed to the winding device 6 through multiple guide rollers in the fixed frame 25. When it is necessary to perform inkjet printing on the web in this area, the driving electric cylinder 26 is started to drive the fixed frame 25 to move, so that the web moves in the direction of the inkjet printing device 3. At this time, the third drive motor 28 is started to drive the rotating screw 27 to rotate, driving the threaded support 29 and the second electric cylinder 2 4 moves laterally in the moving chute, moves the second electric cylinder 24 to the position corresponding to the adjustment frame 18 located between the unwinding device 2 and the inkjet printing device 3, starts the second electric cylinder 24 to drive the electromagnetic socket 31 to move, so that the electromagnetic socket 31 moves into the iron support 30 of the adjustment frame 18, and supplies power to the electromagnetic socket 31 to generate magnetism and magnetically connect with the iron support 30. When the output end of the second electric cylinder 24 continues to move, it drives the corresponding adjustment frame 18 to move in the push chute, so that the web of paper moves between the guide rollers 14 and the ladder frame 17 located on both sides. Then, the first electric cylinder 16 is started to push the ladder frame 17 to move, so that the web of paper remains in a tensioned state and moves toward the inkjet printing device 3. When the web of paper moves from the unwinding device 2 to the rewinding device 6, the inkjet printing device 3 performs printing on the web of paper.

[0045] At this time, the winding device 6 continues to be driven to move, so that the winding device 6 passes through the heating and drying device 4. At this time, by moving the second electric cylinder 24, the second electric cylinder 24 can move the remaining multiple adjustment frames 18 in sequence, and move the multiple guide rollers between the winding device 6 and the unwinding device 2, so that the multiple guide rollers limit the moving path of the web paper, so that the web paper can complete the inkjet printing and heating and drying operations on the web paper in the process of moving from the unwinding device 2 to the winding device 6.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
