[0025] Example 1

[0026] See attached document Figure 1-7This application provides a rapid labeling device for packaging boxes, including a frame 1, a labeling head mechanism 2, a conveyor line 3, and an operation box 4. The conveyor line 3 is installed above the frame 1, and the label head is connected to the frame 1 and positioned above the conveyor line 3. The operation box 4 is connected to the frame 1. The labeling head mechanism 2 includes a labeling head plate 5, a material tray mechanism 6, a roller 7, a label peeling mechanism 8, a traction mechanism 9, a receiving tray 10, and a labeling head driving device 11. The material tray mechanism 6, roller 7, label peeling mechanism 8, traction mechanism 9, receiving tray 10, and labeling head driving device 11 are all installed on the labeling head plate 5. A sensor 5 is provided on the conveyor line 3. 2. For detecting the arrival of the packaging box 55, the label tape is wound on the tray mechanism 6. The above is existing technology and will not be elaborated further. When the label head drive device 11 works, the label tape 53 enters the label peeling mechanism 8 from the tray mechanism 6 via the roller 7. Under the action of the label peeling mechanism 8, the label is separated and affixed to the packaging box 55 conveyed by the conveying mechanism. The separated label tape 53 is pulled into the receiving tray 10 by the traction mechanism 9. The label head mechanism 2 is equipped with a cutting mechanism 12, which is located at the lower right of the tray mechanism 6. It is used to clamp the label tape 53 and cut it when changing to a new label roll to prevent breakage. The label tape 53 falling off affects the replacement efficiency. The cutting mechanism 12 includes a fixing member 13, a connecting plate 14, a pneumatic finger 15, a clamping block 16, a rodless cylinder 17, and a cutting blade 18. The fixing member 13 is installed on the label head plate 5, the connecting plate 14 is installed on the fixing member 13, the pneumatic finger 15 is installed on the connecting plate 14, the clamping block 16 is installed on the output end of the pneumatic finger 15, the rodless cylinder 17 is installed on the connecting plate 14, and the cutting blade 18 is installed on the output end of the rodless cylinder 17. When replacing the label roll, the operation box 4 controls the pneumatic finger 15 to work and drive the cutting blade 18. The clamping block 16 moves inward to clamp the label tape 53, driving the rodless cylinder 17 to work and drive the cutter 18 to cut the label tape 53. After the worker installs the new label roll onto the material tray mechanism 6, he pulls out the end of the new label roll and sticks it to the old label tape 53 clamped on the clamping block 16. The pneumatic finger 15 then releases the label tape 53. The pneumatic finger 15 drives the clamping block 16 to clamp the label tape 53, which facilitates the cutting force of the label tape 53 and prevents the cut label tape 53 from falling and making it inconvenient to connect. The rodless cylinder 17 drives the cutter 18 to automatically cut the label tape 53 without manual operation. The cut is flat and easy to connect, and the structure is simple.

[0027] Example 2

[0028] See attached document Figure 1-7The difference between this embodiment and Embodiment 1 is that the tray mechanism 6 includes a rotating shaft 19, a positioning element 20, an outer cylinder 21, a wedge block 22, a rotating element 23, a tension spring 24, a pressure plate 25, and a compression spring 26. The rotating shaft 19 is rotatably connected to the head plate 5. Three U-shaped positioning strips 27 are fixedly provided inside the outer cylinder 21, evenly distributed on the inner wall of the outer cylinder 21. The positioning element 20 is movably connected to the U-shaped positioning strips 27, which limit its left and right movement. One end of the tension spring 24 is fixedly connected to the positioning element 20, and the other end is fixedly connected to the U-shaped positioning strips 27. Preferably, the U-shaped positioning strips 27 are provided with mounting points for the tension springs 24. The rotating component 23 is threadedly connected to one end of the outer cylinder 21. The rotating component 23 has a first inclined surface 28, and the positioning component 20 has a second inclined surface that cooperates with the first inclined surface 28. By rotating the rotating component 23 inward, the first inclined surface 28 presses the second inclined surface inward, thereby fixing the positioning component 20 to the rotating shaft 19. Conversely, under the tension of the tension spring 24, the positioning component 20 resets and releases the rotating shaft 19. The rotating component 23 includes a wedge-shaped ring 29, which is fixed to the front end of the rotating component 23. The wedge-shaped ring 29 gradually increases in size from the distal end to the proximal end and is conical. The outer cylinder 21 includes a positioning ring 30, which is fixed to the outer cylinder 21. On the outer wall of the outer cylinder 21, the wedge block 22 is provided with a positioning groove 31 that cooperates with the positioning ring 30. The outer cylinder 21 is provided with a square groove 32, and the wedge block 22 is connected to the square groove 32. Through the cooperation of the square groove 32, the positioning ring 30, and the positioning groove 31, the wedge block 22 is limited. Preferably, there are 3 wedge blocks 22, evenly distributed. The wedge blocks 22 are movably connected to the outer cylinder 21. The inner side of the wedge block 22 is connected to the wedge ring 29. By rotating and advancing the wedge ring 29, the wedge block 22 is pushed upward (i.e., outward) to fix the label core 54 of the label roll, thereby realizing the installation and fixation of the label roll. One end of the compression spring 26 is connected to the wedge. Block 22, the other end of the compression spring 26 is connected to the pressure plate 25, the pressure plate 25 is connected to the outer cylinder 21. Conversely, when the wedge ring 29 is rotated out, the spring force of the compression spring 26 drives the wedge block 22 to reset inward and release the label core 54. In actual installation and use, only the rotating shaft 19 of the material tray mechanism 6 is installed on the label head plate 5, while the other components of the material tray mechanism 6 are detachable. During operation, the technician puts the label onto the wedge block 22, and then holds the outer cylinder 21 to align the positioning member 20 with the corresponding position of the rotating shaft 19 and puts it into the rotating shaft 19. After it is in place, the rotating member 23 is rotated forward to press the positioning member 20 inward to press the rotating shaft 19 for fixation.Simultaneously, the wedge-shaped ring 29 advances to lift the wedge-shaped block 22, pressing it upwards against the label core 54 of the label roll for fixation. This allows for quick and easy installation and fixation of the label roll. Conversely, it allows for quick and convenient removal of the label core 54 and replacement with a new label roll. The structure is reasonable and the operation is simple.

[0029] Preferably, the label plate 5 is equipped with a photoelectric sensor 33 for detecting the splicing position. The frame 1 is equipped with a waste removal mechanism 34 for removing damaged labels from the splicing area. The waste removal mechanism 34 includes a fixed frame 35, a transverse module 36, a sliding cylinder 37, and a waste removal plate 38. The fixed frame 35 is mounted on the frame 1, and the transverse module 36 is mounted on the fixed frame 35. The output end of the transverse module 36 is connected to the sliding cylinder 37, and the output end of the sliding cylinder 37 is connected to the waste removal plate 38. When the photoelectric sensor 33 detects the splicing position, it sends a signal to the control center. The control center issues a command to drive the sliding cylinder 37 to extend. The transverse module 36 works to drive the waste removal plate 38 to move, simulating the movement of the packaging box 55, so that the waste labels are affixed to the waste removal plate 38 to achieve waste removal. The structure is reasonable.

[0030] Preferably, the tray mechanism 6 includes a limiting ring 39, which is installed on both sides of the label roll for limiting position.

[0031] Preferably, the head plate 5 is provided with a braking mechanism 40, which includes a spring sleeve 41, a coiled spring 42, a brake shaft 43, a brake arm 44, a roller cylinder 45, and a brake roller 46. The spring sleeve 41 is fixed on the head plate 5, the coiled spring 42 is disposed inside the spring sleeve 41, one end of the brake shaft 43 is connected to the spring sleeve 41 and connected to the coiled spring 42, the brake arm 44 is connected to the other end of the brake shaft 43, the roller cylinder 45 is connected to the brake arm 44, and the brake roller 46 is disposed on the brake arm 44. In this structure, the distance between the roller cylinder 45 and the brake roller 46 is small, and the force on the roller 7 can be quickly transmitted to the brake roller 46 to achieve braking. Therefore, the braking time difference is small. The brake roller 46 includes a brake aluminum roller and a rubber sleeve fitted on the brake aluminum roller. The rubber sleeve has high friction, making the braking more reliable.

[0032] Preferably, the frame 1 is equipped with an emergency stop switch 47 for emergency stopping of the equipment.

[0033] Preferably, the cutting mechanism 12 further includes a soft rubber pad 48, which is installed inside the clamping block 16 to increase friction and make the clamping tighter and more reliable.

[0034] Preferably, the connecting plate 14 is provided with a fixing sleeve 49, which is fixedly connected to the connecting plate 14. The fixing bracket 35 is provided with a mounting short shaft 50, and the fixing sleeve 49 is sleeved on the mounting short shaft 50.
