Technical Field

[0001] The utility model relates to the technical field of logistics labeling equipment, in particular to a labeling device for logistics packaging. Background Art

[0002] In the logistics industry, labeling of packaging boxes is of multiple importance and necessity. Through labeling, goods can be easily classified and identified, which can help logistics personnel quickly understand the properties and characteristics of goods, thereby carrying out effective logistics management and warehousing management.

[0003] The existing labeling device is mainly composed of a feeding mechanism, a label supply system, a labeling mechanism and a control system. During labeling, the box to be labeled is transported to the labeling position through a conveyor belt, and the label roll is smoothly supplied to the labeling mechanism in the label supply system. When the box arrives at the labeling position, the control system issues a command, the labeling mechanism starts working, the peeling plate peels the label from the base paper, the labeling wheel accurately sticks the peeled label on the box, and the pressure wheel applies a certain pressure to ensure that the label is firmly attached to the box, thereby completing the automatic labeling operation and greatly improving the efficiency of labeling.

[0004] Since packaging boxes of different sizes, shapes and uses may need to have labels affixed in different positions, existing labeling devices cannot adjust the labeling position, which limits the labeling device to be used only for specific types of packaging boxes, greatly reducing the versatility and applicability of the equipment; therefore, a labeling device for logistics packaging is proposed to address the above problems.

[0028] Working principle: since packaging boxes of different sizes, shapes and uses may need to have labels affixed at different positions, the existing labeling device cannot adjust the labeling position, which will limit the labeling device to be used only for specific types of packaging boxes, greatly reducing the versatility and applicability of the equipment; therefore, in view of the above problems, a labeling device for logistics packaging is proposed; before labeling, by rotating the rotating nut 6 to move along the threaded rod 3, with the cooperation of the first spring 5, the movable plate 4 can be forced to move, so that the labeling position can be adjusted as needed. The adjustable labeling position can adapt to packaging boxes of different sizes, shapes and uses, greatly enhancing the versatility and flexibility of the labeling machine, and ensuring that the label is accurately affixed to the predetermined position of the packaging box to avoid biased or wrong affixing. After the labeling position adjustment is completed, when labeling, first pass the label in the placement frame 14 from under the limiting wheel 12, and separate the label from the bottom paper below it. The first motor 25 is then started to rotate the winding roller 10, so that the label can be pulled and moved, and the bottom paper is wound around the winding roller 10. When the conveying mechanism conveys the packaging box to the labeling position, the stripping plate 13 peels the label off the bottom paper and accurately sticks the peeled label on the box. The pressing wheel 9 applies a certain pressure to ensure that the label is firmly attached to the box, thereby realizing a fast labeling operation and greatly improving the efficiency of labeling. As the labeling operation continues, the thickness of the bottom paper rolled on the winding roller 10 gradually increases, which will push the square plate 17 and the movable electrode plate 18 to move up, and the second spring 16 is compressed. When the movable electrode plate 18 moves up to contact with the fixed electrode plate 15, the warning light 19 is energized to sound an alarm, thereby reminding the operator to replace the winding roller 10 in time to avoid affecting the subsequent labeling operation.

[0029] When labeling boxes of different heights, the movable block 22 is moved up or down in the slide slot 20, so that the lifting rod 23 is also moved up or down, and the movable plate 4 is forced to move accordingly, so that the height of the label can be adjusted to meet the labeling requirements of boxes of different heights.
