[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-6As shown, this utility model provides a technical solution: a thermal self-adhesive label punching device, including a workbench 1 for supporting all the top components, a punching component 3 for power-driven label punching fixedly installed on the top of the workbench 1, an anti-wrinkle mechanism 2 for tightening the thermal label fixedly installed on the inner wall of the workbench 1, and an interchange mechanism 5 for replacing punching head components of different shapes and sizes fixedly installed inside the punching component 3.

[0024] The workbench 1 provides overall support, and the anti-wrinkle mechanism 2 is fixed to the inner wall of the workbench 1. During operation, it continuously tightens the thermal label to prevent the label from wrinkling during transportation and ensures accurate punching position. The punching component 3 serves as the core of the power drive, which drives the punching head to punch the label under the action of power. When it is necessary to change the punching shape or size for different label specifications, the appropriate punching head component can be quickly replaced by operating the switching mechanism 5, realizing flexible switching of various punching needs. The whole system works together to complete the efficient and accurate punching of thermal self-adhesive labels.

[0025] The anti-wrinkle mechanism 2 includes a first conveying roller 21, a second conveying roller 22, a first fixed plate 23, a second fixed plate 24, a rack 25, and a gear 27. The inner wall of the worktable 1 has an inner groove 26. The two second fixed plates 24 are slidably connected to the inner wall of the inner groove 26. A motor 28 is slidably connected to the inner wall of the inner groove 26. The output end of the motor 28 is fixedly connected to one end of the first conveying roller 21. The first conveying roller 21 is rotatably connected to the inner wall of the second fixed plate 24. The two racks 25 are fixedly connected to the inner wall of the inner groove 26. The gear 27 and the rack 25 mesh with each other.

[0026] When the anti-wrinkle mechanism 2 is working, the motor 28 drives the first conveyor roller 21 to rotate, which works with the second conveyor roller 22 to clamp and convey the thermal label. The inner groove 26 provides sliding space for the second fixed plate 24 and the motor 28. When the conveying distance is adjusted, the gear 27 meshes with the rack 25 on the inner wall of the inner groove 26, driving the second fixed plate 24 and the first conveyor roller 21 to move synchronously, thereby adjusting the distance between them and the second conveyor roller 22. Through the clamping force and synchronous conveying action of the two conveyor rollers, the thermal label can be stretched and flattened, avoiding wrinkles caused by slack during the conveying process, ensuring that the label remains flat when punching, and improving the punching accuracy.

[0027] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, two first fixed plates 23 are fixedly connected to the inner wall of the workbench 1, and a second conveying roller 22 is rotatably connected to the inner wall of the first fixed plates 23. The first conveying roller 21 and the second conveying roller 22 are the same size and are compatible.

[0028] Two first fixed plates 23 are fixed to the inner wall of the workbench 1 to provide stable rotation support for the second conveying roller 22. The first conveying roller 21 and the second conveying roller 22 are the same size and fit each other, forming a symmetrical clamping structure. During operation, the two rollers clamp and convey the thermal label synchronously. Due to the size matching, it can ensure that the label is subjected to balanced force from top to bottom, and avoid the label shifting or wrinkling due to the difference in roller specifications during conveying. With the help of the conveying power, the two rollers work together to convey the label flat to the punching position, laying the foundation for subsequent accurate punching.

[0029] As one implementation method in this embodiment, please refer to Figures 3-5 As shown, the drilling assembly 3 includes a support plate 31, an electric wire 32, and a hydraulic cylinder 33. The support plate 31 is fixedly connected to the top of the workbench 1, the hydraulic cylinder 33 is fixedly connected to the top of the support plate 31, and the electric wire 32 is fixedly connected inside the hydraulic cylinder 33.

[0030] When the punching assembly 3 is working, the support plate 31 is fixed to the top of the workbench 1 to provide stable support for the hydraulic cylinder 33. The wire 32 transmits power to the hydraulic cylinder 33 to drive its operation. The hydraulic cylinder 33, as a power source, generates a telescopic action under the action of electricity, which drives the punching head assembly connected below to move up and down. By controlling the telescopic frequency and stroke of the hydraulic cylinder 33, the punching head can be precisely controlled to punch the thermal labels conveyed below, so as to achieve stable and efficient punching action and adapt to the continuous conveying rhythm of the labels.

[0031] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the switching mechanism 5 includes a connecting rod 51, a lock housing 52, a locking block 54, and a punch 55. The connecting rod 51 is fixedly connected to the output end of the hydraulic cylinder 33, and the lock housing 52 is fixedly connected to the bottom of the connecting rod 51. A cross groove 53 is provided inside the lock housing 52, and a spring 56 is fixedly connected to the inner wall of the lock housing 52.

[0032] When the replacement mechanism 5 is working, the connecting rod 51 transmits the power of the hydraulic cylinder 33 to the lock housing 52. The cross groove 53 inside the lock housing 52 is used to adapt to the corresponding structure of the punch 55 to achieve initial positioning. The spring 56 provides elastic force to push the locking block 54 to engage with the punch 55, and securely lock the punch 55 in the lock housing 52. When replacing the punch 55, press the locking block 54 to compress the spring 56, release the lock, and the old punch 55 can be removed. After the new punch 55 is installed, the spring 56 returns to its original position, causing the locking block 54 to re-engage, quickly completing the replacement of punches 55 of different specifications and meeting diverse drilling needs.

[0033] As one implementation method in this embodiment, please refer to Figure 5 As shown, the locking block 54 is fixedly connected to the outer wall of the punch 55, and the locking block 54 engages with the cross groove 53.

[0034] The locking block 54 on the outer wall of the punch 55 engages with the cross groove 53 inside the lock housing 52. With the help of the spring 56, the locking block 54 is firmly embedded in the groove, thus fixing the punch 55 in place. When replacing, the locking block 54 disengages from the groove under external force, allowing the punch 55 to be removed easily.

[0035] As one implementation method in this embodiment, please refer to Figure 2 As shown, a placement slot 4 is provided on the top of the workbench 1, and the punch 55 is located directly above the placement slot 4.

[0036] The placement slot 4 at the top of the workbench 1 provides working space for label punching, with the punch 55 positioned directly above it. During punching, the punch 55 moves downwards, precisely aligning with the placement slot 4 to avoid impact damage to the workbench 1, while ensuring accurate label punching and improving operational stability.

[0037] Working principle: The workbench 1 provides support for the whole. In the anti-wrinkle mechanism 2, the motor 28 drives the first conveyor roller 21 to rotate, which works with the second conveyor roller 22 to clamp and convey the thermal label. The inner groove 26 on the inner wall of the workbench 1 provides sliding space for the second fixed plate 24 and the motor 28. When adjusting the conveying distance, the gear 27 meshes with the rack 25 on the inner wall of the inner groove 26, which drives the second fixed plate 24 and the first conveyor roller 21 to move synchronously, thereby adjusting the distance between them and the second conveyor roller 22. The two first fixed plates 23 are fixed to the inner wall of the workbench 1 to provide stable support for the second conveyor roller 22. The first conveyor roller 21 and the second conveyor roller 22 are the same size and can be matched to each other, so that the label can be stretched and flattened evenly and conveyed smoothly to the punching position.

[0038] The support plate 31 of the punching assembly 3 is fixed to the top of the workbench 1 to provide support for the hydraulic cylinder 33. The wire 32 transmits power to the hydraulic cylinder 33 to drive its extension and retraction, which drives the lower replacement mechanism 5 to move. The connecting rod 51 of the replacement mechanism 5 transmits the power of the hydraulic cylinder 33 to the lock housing 52. The cross groove 53 inside the lock housing 52 is adapted to the structure of the punch 55. The spring 56 pushes the locking block 54 on the outer wall of the punch 55 to engage with the cross groove 53 to fix the punch 55. When replacing, pressing the locking block 54 can be used. The placement slot 4 on the top of the workbench 1 provides space for punching. The punch 55 is located directly above it to ensure accurate punching without damaging the workbench 1. All components work together to achieve efficient and accurate punching.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
