[0027] Please refer to Figures 1-5 , a die-cutting device for carton processing, which includes a fixed frame 1. A locking component is arranged on the fixed frame 1 through a clamping component. The locking component includes a fixed rod 2, a rotating seat 3, a die-cutting knife 4, an inserting rod 5, a mounting sleeve 6 and a pulling plate 7. The fixed rod 2 is fixedly installed on the fixed frame 1. The rotating seat 3 is rotatably connected to the fixed rod 2. The die-cutting knife 4 is inserted inside the rotating seat 3. Through holes are opened on the rotating seat 3 and the die-cutting knife 4. The inserting rod 5 is inserted into the rotating seat 3. The inserting rod 5 is adapted to the through hole. The mounting sleeve 6 is sleeved outside the inserting rod 5. One end of the mounting sleeve 6 abuts against one end of the rotating seat 3. The pulling plate 7 is slidably connected to the mounting sleeve 6. The clamping component includes an inserting groove 8, a locking block 9 and a spring 10. The inserting groove 8 is opened on the inserting rod 5. The locking block 9 is slidably connected to the mounting sleeve 6. The locking block 9 is adapted to the inserting groove 8. The spring 10 is connected between the outside of the mounting sleeve 6 and the locking block 9. A fixing component is arranged on the fixed frame 1.

[0028] A pulling rod 11 is connected to the pulling plate 7. A tension spring 12 is sleeved outside the pulling rod 11. The tension spring 12 is connected between the pulling plate 7 and the outside of one end of the mounting sleeve 6. A moving plate 13 is connected to the pulling rod 11. The moving plate 13 is adapted to the locking block 9. The moving plate 13 is slidably connected to the outside of the mounting sleeve 6.

[0029] A limiting block 14 is connected to one end of the pulling rod 11. A rotating block 15 is rotatably connected to one end of the mounting sleeve 6.

[0030] A rotating groove 16 is opened on the rotating block 15. The rotating groove 16 is adapted to the pulling rod 11. A limiting groove 17 is opened on the rotating groove 16. The limiting groove 17 is adapted to the limiting block 14.

[0031] In this embodiment, during the use process, when it is necessary to release the fixation of the die-cutting knife 4, the rotating block 15 is rotated manually along one end of the mounting sleeve 6. During the rotation process, the limiting groove 17 of the rotating block 15 is moved to a position adapted to the limiting block 14. At this time, the pulling plate 7 is moved manually. During the movement process, the tension spring 12 is stretched, and the pulling rod 11 is driven to move. Moreover, when the pulling rod 11 moves, the moving plate 13 is driven to slide along the outer side of the mounting sleeve 6. As the moving plate 13 moves, the pushing process of the locking block 9 is released. Moreover, when the pushing is released, under the action of the spring 10, the locking block 9 is driven to move outward, so that the locking block 9 is separated from the insertion groove 8 on the insertion rod 5, and the fixing process of the insertion rod 5 is released. At this time, the mounting sleeve 6 is slid out along the insertion rod 5, then the insertion rod 5 is slid out along the rotating seat 3, then the die-cutting knife 4 is removed, then the die-cutting knife 4 is re-placed inside the rotating seat 3, then the insertion rod 5 is inserted into the rotating seat 3 and the die-cutting knife 4, then the mounting sleeve 6 is inserted along the insertion rod 5 again. And after the fixing process of the insertion rod 5 is completed, the rotating block 15 is rotated so that the limiting groove 17 of the rotating block 15 is far away from the limiting block 14, so as to drive one end of the limiting block 14 to fit with one end of the rotating block 15 by cooperating with the tension spring 12, and the replacement process of the die-cutting knife 4 is completed.

[0032] Please refer to Figures 1-2 , as an embodiment of a die-cutting device for carton processing of the fixing component: The fixing component includes a conveying roller 18, a cylinder 19 and a moving rod 20. The conveying rollers 18 are evenly rotatably connected to the fixing frame 1. The cylinder 19 is hinged to the fixing frame 1. The moving rod 20 is slidably connected to the fixing frame 1. The output end of the cylinder 19 is hinged to the moving rod 20.

[0033] A stabilizing frame 21 is installed on the fixing frame 1, and a threaded rod 22 is threadedly connected to one end of the stabilizing frame 21.

[0035] A pressing wheel 25 is installed at the bottom of the pressing frame 24.

[0036] More specifically, during use, place the cardboard box on the conveying roller 18, and use the conveying roller 18 to convey the cardboard box. When it moves to the stabilizing frame 21, manually rotate the threaded rod 22, which drives the pressing frame 24 to slide along the guiding rod 23 at one end. And make the pressing wheel 25 at the bottom of the pressing frame 24 abut against the top of the cardboard box, so as to complete the fixing process of the cardboard box. Then manually start the cylinder 19, which drives the moving rod 20 at the output end to move along the fixed frame 1. During the moving process, it drives the rotating seat 3 to rotate along the fixed rod 2, thereby driving the die-cutting knife 4 on the rotating seat 3 to perform die-cutting on the fixed cardboard box.

[0037] In summary, when the whole equipment is in use or operation: during use, when it is necessary to release the fixation of the die-cutting knife 4, manually rotate the rotating block 15 along one end of the mounting sleeve 6. During the rotation process, move the limiting groove 17 of the rotating block 15 to a position adapted to the limiting block 14. At this time, manually move the pulling plate 7. During the moving process, stretch the tension spring 12 and drive the pulling rod 11 to move. Moreover, when the pulling rod 11 moves, drive the moving plate 13 to slide along the outside of the mounting sleeve 6. As the moving plate 13 moves, release the abutting process on the locking block 9. And when the abutting is released, under the action of the spring 10, drive the locking block 9 to move outward, so that the locking block 9 leaves the insertion groove 8 on the insertion rod 5, thus releasing the fixing process of the insertion rod 5. At this time, slide the mounting sleeve 6 along the insertion rod 5 and take it out, then slide the insertion rod 5 along the rotating seat 3 and take it out, then remove the die-cutting knife 4, then place the die-cutting knife 4 back inside the rotating seat 3, then insert the insertion rod 5 into the rotating seat 3 and the die-cutting knife 4, then insert the mounting sleeve 6 back along the insertion rod 5. And after completing the fixing process of the insertion rod 5, rotate the rotating block 15 so that the limiting groove 17 of the rotating block 15 is away from the limiting block 14, so as to drive one end of the limiting block 14 to fit with one end of the rotating block 15 with the cooperation of the tension spring 12, thus completing the replacement process of the die-cutting knife 4.

[0038] During use, place the cardboard box on the conveying roller 18 to convey the cardboard box by means of the conveying roller 18. When it moves to the stabilizing frame 21, manually rotate the threaded rod 22 to drive the pressing frame 24 to slide along the guiding rod 23 at one end, and make the pressing wheel 25 at the bottom of the pressing frame 24 abut against the top of the cardboard box to complete the fixing process of the cardboard box. Then, manually start the air cylinder 19 to drive the moving rod 20 at the output end to move along the fixing frame 1. During the moving process, drive the rotating seat 3 to rotate along the fixing rod 2, so as to drive the die-cutting knife 4 on the rotating seat 3 to perform die-cutting on the fixed cardboard box.
