With each rotation, a label is positioned on positioning plate 37, waiting for subsequent adsorption by pneumatic suction cup 55.

[0035] Precise material handling and transfer: The three-axis electric guide rail works in conjunction to move the pneumatic suction cup 55 above the label; after the pneumatic suction cup 55 picks up the label, the rotating table 2 will precisely transfer the label to the product's pressing surface during rotation.

[0036] Pressing and quality control: Cylinder 7 pushes pressing plate 8 downward to apply pressure evenly, ensuring that the label and product are completely adhered; after pressing is completed, cylinder 7 resets, solenoid valve 13 opens instantly, and air nozzle 11 sprays airflow to blow the product onto unloading platform 14 for collection.
