Description

Technical Field

[0001] This utility model relates to the field of material processing technology, and in particular to an adjustable label cutting device. Background Technology

[0002] Labels are used to identify the target and category or content of a product. In the printing industry, labels are mostly printed materials used to identify relevant instructions for their products, and most of them have adhesive backing. However, some are printed without adhesive and can also be called labels.

[0003] Common label cutting equipment mainly consists of a feeding mechanism, a cutting mechanism, and a conveying mechanism, using mechanical limits or photoelectric sensors to initially determine the label cutting position. However, in actual production, due to factors such as the flatness of the label material itself and the operational stability of the feeding roller and conveyor belt during feeding and conveying, labels are prone to shifting. Existing positioning devices can only provide coarse adjustments to the label position to a certain extent and cannot accurately and dynamically correct the label shift based on real-time offset, affecting the quality of label cutting and production efficiency. Therefore, an adjustable label cutting device is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 4An embodiment of this utility model provides an adjustable label cutting device, including a fixed frame 1, a feeding roller 2 rotatably connected to the outside of the fixed frame 1, a correction component installed on the inside of the fixed frame 1, a connecting frame 6 installed on the top of the fixed frame 1, and a cutting component installed inside the connecting frame 6; the correction component includes a connecting block 5, the connecting block 5 is fixedly connected to the top of the fixed frame 1, a connecting plate 16 is fixedly connected to the inside of the connecting block 5, a cylinder 15 is fixedly connected to the bottom of the connecting plate 16, a slider 20 is fixedly connected to the output end of the cylinder 15, and a correction block 18 is fixedly connected to the top of the slider 20. The correction assembly also includes a slide bar 21, which is fixedly connected to the inner side of the connecting block 5. The correction block 18 is slidably connected to the outside of the slide bar 21. The extension and retraction of the cylinder 15 pushes the slider 20 to move, and the extension and retraction of the cylinder 15 pushes the slider 20 to slide, thereby causing the correction block 18 to slide on the slide bar 21 to correct the label. A rack 25 is fixedly connected to the bottom of the slider 20, and a gear 22 is rotatably connected to the top of the connecting plate 16. The gear 22 meshes with the rack 25. At the same time, the rack 25 moves with the slider 20, driving the gear 22 to rotate. The rotation of the gear 22 drives the other rack 25 to slide, thereby adjusting the position of the correction block 18. A second drive motor 17 is fixedly connected to the outside of the fixed frame 1. A rotating shaft 23 is fixedly connected to the output end of the second drive motor 17. A conveyor belt 9 is sleeved on the outside of the rotating shaft 23. The second drive motor 17 drives the rotating shaft 23 to rotate, causing the externally sleeved conveyor belt 9 to move accordingly, conveying the cut labels. A fixed plate 24 is fixedly connected inside the fixed frame 1, and a conveyor belt 9 is sleeved on the outside of the fixed plate 24. Rollers 3 are rotatably connected to the inside of the fixed frame 1, and an auxiliary roller 4 is fixedly connected to the inside of the connecting block 5. A collection box 8 is fixedly connected to the outside of the fixed frame 1 to collect the cut labels for easy processing in the next stage. A slide rail 19 is fixedly connected to the top of the connecting plate 16, and a slider 20 is slidably connected to the outside of the slide rail 19.

[0033] Reference Figure 1 and Figure 3 The cutting assembly includes a drive motor 12, which is fixedly connected to the outside of the connecting frame 6. An eccentric wheel 7 is fixedly connected to the output end of the drive motor 12, and a connecting shaft 11 is fixedly connected to the outside of the eccentric wheel 7. A slide groove 13 is slidably connected to the inside of the connecting frame 6, with the middle of the slide groove 13 slidably connected. A connecting rod 10 is fixedly connected to the outside of the slide groove 13, and a cutting blade 14 is fixedly connected to the bottom of the connecting rod 10. When the eccentric wheel 7 rotates, it drives the slide groove 13 to reciprocate within the connecting frame 6 via the connecting shaft 11. Because the connecting rod 10 is fixedly connected to the outside of the slide groove 13, and the cutting blade 14 is fixedly connected to the bottom of the connecting rod 10, the reciprocating motion of the slide groove 13 drives the cutting blade 14 to reciprocate up and down, quickly cutting the label and improving cutting efficiency to meet the high-efficiency requirements of the production process.

[0034] Working principle: The label material is wound around the feeding roller 2. As the feeding roller 2 rotates, the label material is released. The roller 3 assists in the smooth transport of the label material. At the same time, the drive motor 12 is started to drive the eccentric wheel 7, which drives the connecting shaft 11 to slide inside the slide groove 13. This, in turn, drives the connecting rod 10 to move up and down with the movement of the slide groove 13, so that the cutting blade 14 cuts the label material into individual labels as required. Meanwhile, the drive motor 17 drives the rotating shaft 23 to rotate, which in turn drives the conveyor belt 9 to transport the label material forward into the collection box 8.

[0035] When the label material deviates during transport, cylinder 15 activates to move slider 20 and slide correction block 18 on slide rod 21, adjusting the position of the label material. Simultaneously, rack 25 connected to the bottom of slider 20 meshes with gear 22 rotatably connected to the top of connecting plate 16. Rack 25 drives gear 22 to rotate, enabling correction of labels of different sizes, ensuring the label material remains on the correct transport path and providing accurate positioning for subsequent cutting processes.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
