By setting inspection points on the conveyor chain in the direction of bottle feeding, the operating speed of the equipment is automatically controlled. The bottles are conveyed to the rotating mechanism through rotation, and the equipment starts to operate automatically after receiving the bottle feeding signal feedback from the detection device. After the label is corrected, it enters the label cutting wheel and is cut into the specified length. The cut labels are vacuum adsorbed onto the label wheel, and the rotating label cutting wheel rotates around the rubber roller to attach the labels with hot melt adhesive at both ends to the bottles on the main rotating table. After the bottle is flattened with a label brush, the labeling process is completed. At the same time, the operating speed of the equipment is controlled through the detection points set on the bottle outlet chain.
