The labeling device 2 comprises an unreeling shaft 21 for releasing the labels, a stripping plate 23 for stripping the labels and a reeling shaft for reeling the base band, the stripping plate 23 is arranged obliquely from top to bottom along the conveying direction of the conveying device 1, and the unreeling shaft 21 and the reeling shaft rotate synchronously and intermittently. The rolling device 3 is arranged in front of the stripping plate 23, the rolling device 3 comprises a rolling shaft 31, the rolling shaft 31 is horizontally arranged and intermittently ascends and descends, and the rolling shaft 31 is rotatably arranged. The sensor is arranged on the second support frame 6 and is opposite to the conveying device 1, and the controller controls the intermittent motion of the unreeling shaft 21, the reeling shaft and the rolling shaft 31 by means of information detected by the sensor. Specifically, the sensors include a first sensor 41 for detecting whether a product is on the conveyor 1 and a second sensor 42 for detecting whether a label is on the product. When the first sensor 41 detects that the conveying device 1 has a product, the controller controls the unwinding shaft 21 to unwind and controls the winding shaft to wind, so that the label is peeled by matching with the peeling plate 23, and the passing product drags the peeled label to be adhered to the surface of the product through the viscosity of the label; when the second sensor 42 detects that the product on the conveying device 1 has a label, the controller controls the rolling shaft 31 to descend so as to compact the attached label; in the compacting process, the rolling shaft 31 is driven to roll due to the movement of the product, so that the friction between the rolling shaft 31 and the label and the surface of the product is reduced, and the damage of the label or the slow moving speed of the product is avoided; when the rolling shaft 31 rolls for a certain time, the controller controls the rolling shaft 31 to ascend so as to provide an avoiding space for the moving product, the moving speed of the product is guaranteed, and the compacted label is not damaged. More specifically, the following:
