It is transported toward one side of the labeling roller 8. When the article passes through the labeling roller 8, the elastic mechanism 13 is used to press down the connecting arm 7 elastically, so that the labeling roller 8 can elastically contact with the surface of the article. As a result, when the article is transported through the labeling roller 8, the label can be tightly attached to the article to achieve the purpose of labeling. Under the control of the PLC control cabinet 1, the base tape rewinding roller 6 rewinds the remaining base tape after labeling, and cooperates with the continuous transportation of the article by the conveyor table 2 to realize continuous labeling operation of the article. The overall structure is reasonable, which ensures that the label is tightly attached to the surface of the article, improves the labeling effect, and avoids the phenomenon that the label is not tightly attached and is easy to fall off.

[0027] In this embodiment, the vertical arm 3 includes a fixed arm 9 vertically fixed on one side of the PLC control cabinet 1 and a movable arm 10 movably arranged on the top of the fixed arm 9. A driving mechanism 11 for driving the movable arm 10 to rise and fall is arranged on the fixed arm 9. A horizontal arm 4 is horizontally fixed on the top of the movable arm 10, and a barcode label roller 5 and a base tape winding roller 6 are installed at both ends of the horizontal arm 4.

[0028] Furthermore, a fixed block 12 is fixed on the side wall of the movable arm 10, and the connecting arm 7 is rotatably connected to the fixed block 12. The fixed block 12 includes a sleeve 16 fixed on the fixed block 12, a shaft 15 inserted in the sleeve 16, and a torsion spring 17 sleeved between the shaft 15 and the inner wall of the sleeve 16. The shaft 15 is coaxially connected to the rotating axis of the connecting arm 7, and the torsion spring 17 is used to generate axial torsion on the shaft 15 to drive the connecting arm 7 to drive the labeling roller 8 to be elastically pressed downward.

[0029] Furthermore, a through groove 18 capable of accommodating the vertical movement of the fixed block 12 is vertically opened on the side wall of the fixed arm 9.

[0032] Working principle: When in use, the barcode label means is wound around the base tape winding roller 6 from the barcode label roller 5, around the labeling roller 8, and the object is transported from the barcode label roller 5 to the labeling roller 8 on the conveyor platform 2. When the object passes through the labeling roller 8, the axial torque generated by the torsion spring 17 on the shaft 15 drives the connecting arm 7 to elastically press down, so that the labeling roller 8 can elastically contact with the surface of the object. Therefore, when the object is transported through the labeling roller 8, the label can be tightly attached to the object to achieve the purpose of labeling, and under the control of the PLC control cabinet 1, the base tape winding roller 6 rewinds the remaining base tape after labeling, and cooperates with the continuous transportation of the object by the conveyor platform 2 to realize continuous labeling operation of the object. The overall structure is reasonable. By setting the labeling roller 8 to drive the label elastic pressure, it can ensure that the label is tightly attached to the surface of the object, improves the labeling effect, and avoids the phenomenon that the label is not tightly attached and easy to fall off. Furthermore, by utilizing the paddle 14 provided on the connecting arm 7 and the paddle 14 being bent upward toward one end of the fixed block 12, before the object is transported through the labeling roller 8, the object will first push the paddle 14 to cause the connecting arm 7 to drive the labeling roller 8 to move upward, so as to ensure that the labeling roller 8 can push the label to roll on the surface of the object for labeling, thereby avoiding the phenomenon of jamming at the labeling roller 8 during the transportation of the object. The structure is more reasonable and ensures the smoothness of labeling. Furthermore, by starting the driving motor 20 to drive the screw column 19 to rotate, the movable arm 10 is driven to rise and fall, which can drive the barcode label roller 5, the base tape winding roller 6 and the connecting arm 7 to rise and fall as a whole, and can adapt to the labeling of objects of different heights, with high adaptability.
