The second gears 51 mesh with each other.

[0023] like Figure 2 and Figure 5 As shown, it also includes a tension adjustment assembly, which includes a rodless cylinder 9, a sliding block 10, and a tension adjustment rod 11. The left coil rack 2 is connected to the roller-driven die-cutting machine 1 at both the front and rear ends by rodless cylinders 9, and the right coil rack 2 is also connected to the roller-driven die-cutting machine 1 at both the front and rear ends by rodless cylinders 9. Sliding blocks 10 are connected to the sliders of the rodless cylinders 9, and tension adjustment rods 11 are rotatably connected between two adjacent sliding blocks 10 at the front and rear ends.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, it also includes a limiting component, which includes a support block 12, a connecting rod 13, a third motor 14, a bidirectional lead screw 15, and a limiting block 16. The upper part of the roller-driven die-cutting machine 1 is connected to two sets of support blocks 12, each set consisting of two support blocks 12, one in front and one in back. The support blocks 12 in the same set are rotatably connected to the connecting rods 12. The front side of the connecting rods 13 is connected to the third motor 14. The output shaft of the third motor 14 is connected to the bidirectional lead screw 15. The bidirectional lead screw 15 is rotatably connected to the adjacent connecting rod 13. The front and rear parts of the bidirectional lead screw 15 are threadedly connected to the limiting block 16. The limiting block 16 is slidably connected to the adjacent connecting rod 13.

[0025] like Figure 5 As shown, it also includes a receiving sensor 17 and a feeding sensor 18. The receiving sensor 17 is connected to the lower part of the roller-driven die-cutting machine 1, and the feeding sensor 18 is connected to the lower part of the roller-driven die-cutting machine 1. The feeding sensor 18 is located behind the receiving sensor 17. Both the receiving sensor 17 and the feeding sensor 18 are electrically connected to the control cabinet 3.

[0026] When using this device, first place the roller-driven die-cutting machine 1 in the automatic label feeding area. Then, place the roll core to be cut onto the unloading roller 7. Next, install the unloading roller 7 between the left connecting shafts 61. Then, place the take-up roll core onto the upper take-up roller 71. Then, install the take-up roller 71 between the right connecting shafts 61. Next, move the paper clamping ring 6 inward to limit the roll core to be cut. Then, stretch the roll core out and pass it in sequence around the tension adjusting rod 11, guide rod 8 and connecting rod 13 near the unloading roller 7 before entering the roller-driven die-cutting machine 1. The roll core then passes in sequence around the connecting rod 13, guide rod 8 and tension adjusting rod 11 near the take-up roller 71 before winding onto the take-up roll core on the take-up roller 71. Finally, the paper clamping ring 6 moves inward to take the roll core. The core is positioned, then the third motor 14 is started, driving the bidirectional lead screw 15 to rotate. This causes the limiting blocks 16 to move along the connecting rod 13 under the action of the thread, bringing the limiting blocks 16 closer together to assist in correcting the deviation of the coiled material. Then, the device is started via the control cabinet 3, causing the first motor 4 to start, driving the first gear 5 to rotate. The first gear 5 meshes with each other, driving the connecting shaft 61 to rotate, causing the unloading roller 7 to rotate. This loosens the coiled material on the unloading roller 7. Simultaneously, the rodless cylinder 9 near the unloading roller 7 controls the sliding block 10 to move downwards, causing the tension adjusting rod 11 near the unloading roller 7 to move downwards. When the coiled material is loosened and pulled down to a certain position by the tension adjusting rod 11, the feeding sensor 18 is triggered, and the first motor 4 is started via the control cabinet 3. Motor 4 stops working, and the material to be cut stops unwinding to avoid excessive unwinding and surface contamination. The material is then cut by the roller-driven die-cutting machine 1 and moves to the right. This causes the rodless cylinder 9 near the take-up roller 71 to control the slider to move downwards, which in turn moves the tension adjusting rod 11 near the take-up roller 71 downwards. The cut material is then pulled downwards by the tension adjusting rod 11. When the cut material is pulled to the trigger height of the take-up sensor 17, the sensor is triggered, causing the second motor 41 to start. This drives the second gear 51 to rotate. The meshing motion of the second gears 51 drives the right-side connecting shaft 61 to rotate, causing the take-up roller 71 to rotate, thus winding the cut material onto the take-up drum. The tension adjusting rod 11 keeps the rolled material flat and taut. As the rolled material is collected, the rodless cylinder 9 near the take-up roller 71 controls the slider to move upward, which in turn moves the tension adjusting rod 11 upward. This causes the rolled material at the take-up position to move away from the trigger height of the take-up sensor 17, stopping the second motor 41 and achieving timely material take-up. At the same time, the rolled material released by the unloading roller 7 is tightened. At this time, the rodless cylinder 9 drives the sliding block 10 to move upward, causing the tension adjusting rod 11 near the unloading roller 7 to move upward. When the rolled material released by the unloading roller 7 moves away from the trigger height of the feeding sensor 18, the first motor 4 starts again to unload the rolled material to be cut. Then, the above operation is repeated to achieve automatic material take-up and feeding.It can promptly adjust the take-up and feeding actions and paper tension, and provides auxiliary correction to prevent roll deviation, improving production efficiency and quality. When the core needs to be removed and replaced, the paper clamping ring 6 can be moved outward on the connecting shaft 61 so that the paper clamping ring 6 is no longer in contact with the core. Then, the feed roller 7 and take-up roller 71 are removed from the connecting shaft 61, and the core is taken out. The new core is then placed on the feed roller 7 and take-up roller 71 respectively. The feed roller 7 and take-up roller 71 are then installed between the connecting shaft 61. The paper clamping ring 6 is then moved inward to limit the core, thus facilitating the removal of the cut roll material. The operation is simple and convenient.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
