[0030] See also Figure 1-7 As shown, the present invention is a striping structure for digital printing, comprising an adjustment structure 1, wherein the two bases 11 of the adjustment structure 1 are fixed relative to the ground. The top surfaces of the two bases 11 are located on the same horizontal line, and two sliding rails 12 are fixedly connected to the top surface of each base 11. The top surfaces of the two sliding rails 12 on the top surface of the same base 11 are slidably connected to a sliding seat 13. A transmission screw 15 is rotatably provided above one side of the sliding seat 13. The transmission screw 15 is arranged in a horizontal direction, passes through the corresponding sliding seat 13 and is threadedly connected. One end of the transmission screw 15 is fixedly connected to a handwheel 14. A clamping block 16 is fixedly connected to the side of the sliding seat 13, and the rotating shaft 33 of the handwheel 14 passes through the inside of the clamping block 16. A screw handle 17 is provided on the surface of the clamping block 16. By rotating the screw handle 17, the clamping block 16 can be pressed, thereby fixing the handwheel 14 and the transmission screw 15.

[0031] The top surfaces of the two sliding seats 13 are provided with a cutting structure 2, and the side panels 21 of the cutting structure 2 are fixedly connected to the top surfaces of the sliding seats 13. A discharge guide roller 4 and a recovery guide roller 5 are rotatably connected between the two side panels 21. The discharge guide rollers 4 and the recovery guide rollers 5 are parallel to each other and located in the same horizontal plane. A servo motor 22 is fixedly connected to the outer surface of one of the side panels 21, and the output end of the servo motor 22 is arranged horizontally. A synchronous wheel 23 is rotatably connected to the outer surface of this side panel 21. The synchronous wheel 23 is located below the servo motor 22 and has a plurality of meshing teeth on its surface. The output end of the servo motor 22 and the synchronous wheel 23 are synchronized by a rack (not shown). A semicircular mounting seat 37 is fixedly connected to the side of the side panel 21 facing away from the synchronous wheel 23. A rotating seat 39 is rotatably mounted within the mounting seat 37. The rotating seat 39 is fixedly connected to one side of the synchronous wheel 23 and has a straight-line groove defined on its top surface. The other side panel 21 is equipped with a similar mounting base 37 and rotating base 39. A lower cutter shaft 24 is removably mounted between the rotating bases 39. The lower cutter shaft 24 is formed into transverse blocks 210 at each end. The lower cutter shaft 24 engages the rotating base 39 via these blocks. Fixed covers 38 are removably attached to the top surfaces of the mounting bases 37. The lower cutter shaft 24 is positioned between the discharge guide roller 4 and the return guide roller 5. A driving bevel gear 25 is sleeved and connected to the surface of the lower cutter shaft 24. The driving bevel gear 25 is located on the end closest to the servo motor 22.

[0032] A mounting structure 3 is provided between the two side panels 21. Swing arms 32 are rotatably connected to the opposing surfaces of the two side panels 21. A rotating shaft 33 is fixedly connected between the two swing arms 32. The rotating shaft 33 is located at the end of the swing arms 32 away from the lower blade shaft 24. An upper blade shaft 27 is detachably provided at the end of each swing arm 32 near the lower blade shaft 24. A slot is provided above the swing arms 32 for positioning the rotating shaft of the upper blade shaft 27. The upper blade shaft 27 is positioned on the top surface through the slot. A fixing block 34 is detachably provided at the mounting end of the swing arms 32 to secure the rotating shaft of the upper blade shaft 27. Positioning blocks 35 are fixedly connected to the opposing surfaces of the two side panels 21. The positioning blocks 35 are located below the swing arms 32. The top surface of the positioning blocks 35 is horizontal, so that the swing arms 32 contact the top surface of the positioning blocks 35 during their swinging, positioning the swing arms 32 horizontally. In this case, the upper blade shaft 27 is positioned above the lower blade shaft 24. The upper blade shaft 27 is sheathed with a transmission bevel gear, with the driving bevel gear 25 meshingly connected to the transmission bevel gear. A circular upper blade 29 is sheathed on the upper blade shaft 27, while a backing ring 26 is sheathed on the lower blade shaft 24, located to one side of the upper blade 29. A speed reducer 36 is fixedly connected to the outer surface of the side panel 21, facing away from the servo motor 22. A handle 31 is attached to the surface of the speed reducer 36, which is in transmission connection with the rotating shaft 33 via the speed reducer 36.

[0033] When using this digital printing striping structure, the printed paper to be striped is placed on the discharge paper guide roller 4. One end of the printed paper passes through the gap between the upper blade 29 and the lower blade, and is then placed on the recovery paper guide roller 5 on the other side. By turning the screw handle 17, the handwheel 14 and the transmission screw 15 are released. Turning the handwheel 14 causes the transmission screw 15 to rotate, thereby driving the threaded sliding seat 13 to move. The sliding seat 13 is limited by the sliding rail 12, so that the sliding seat 13 drives the entire striping structure to move and adjust the position of the striping structure. The position is then positioned and fixed by turning the screw handle 17. By starting the servo motor 22, the output end of the servo motor 22 drives the synchronous wheel 23 to rotate, and the synchronous wheel 23 drives the lower cutter shaft 24 to rotate. The lower cutter shaft 24 drives the upper cutter shaft 27 to rotate through the bevel gear on the surface, causing the upper blade 29 on the surface of the upper cutter shaft 27 to rotate and cut. The printed paper can be cut into strips by passing through the gap, and then enters the recycling paper guide roller 5 for recycling. When the upper blade 29 needs to be replaced and cleaned, the handle 31 is turned, and the handle 31 indirectly drives the rotating shaft 33 to rotate through the speed reducer 36. The rotating shaft 33 drives the swing arms 32 at both ends to swing upward, so that the driven bevel gear 28 of the upper cutter shaft 27 is disengaged from the active bevel gear 25. At this time, the upper blade 29 is suspended for easy replacement. The lower cutter shaft 24 is rotatably connected to the side plate 21 through the setting seats 37 on both sides. The fixed cover 38 on the top surface of the setting seat 37 is removed, and the rotating seat 39 inside the setting seat 37 is exposed. A block 210 is set at both ends of the lower cutter shaft 24. The lower cutter shaft 24 is engaged with the rotating seat 39 through the block 210, so that the lower cutter shaft 24 can be directly taken out from the rotating seat 39 to replace the cutter seat.

[0034] The working principle of the utility model is as follows: the utility model is a digital printing striping structure, by setting a cutting structure 2 and a mounting structure 3, the upper cutter shaft 27 and the lower cutter shaft 24 of the cutting structure 2 rotate synchronously, and the upper blade 29 on the surface of the upper cutter shaft 27 cuts the printed paper into strips; when the upper cutter shaft 27 and the lower cutter shaft 24 need to be replaced and cleaned, the swing arms 32 on both sides are indirectly driven to rotate upward by rotating the handle 31, thereby driving the upper cutter shaft 27 to separate from the transmission of the lower cutter shaft 24, and the upper blade 29 on the surface of the upper cutter shaft 27 is suspended for easy replacement. Replace and clean; the one-shaped blocks 210 on both sides of the lower cutter shaft 24 are engaged with the rotating seat 39, and the lower cutter shaft 24 can be directly and completely removed from the rotating seats 39 on both sides; by setting the adjustment structure 1, the handwheel 14 of the adjustment structure 1 can drive the transmission screw 15 to rotate, so that the two sliding seats 13 move along the sliding rail 12, and the overall position of the striping structure is changed; the handwheel 14 is set in the clamping block 16, and the handwheel 14 and the transmission screw 15 can be fixed by rotating the screw handle 17, thereby fixing the overall position of the striping structure.
