The PLC controller controls the third conveyor belt 36 to stop conveying and controls the external vacuum machine 34 to start working. At this time, the existing suction cup 341 in the external vacuum machine 34 opens the bag opening of the vacuum bag, and its vacuum nozzle 342 enters the vacuum bag. Its pressure strip 343 presses the bag opening of the vacuum bag, and the vacuum pump of the external vacuum machine 34 starts to evacuate the bag, and the vacuum is completed after 15 seconds. The vacuum is formed, the suction nozzle 342 of the external vacuum machine 34 is retracted, and the pressure strip 343 of the external vacuum machine 34 performs hot-pressing sealing for 10 seconds. The PLC controller controls the third conveyor belt 36 to continue conveying. When the vacuum-bagged product touches the second proximity sensor 38, the second proximity sensor 38 transmits a trigger signal to the PLC controller, and the PLC controller controls the third conveyor belt 36 to stop conveying, and controls the automatic labeling machine 35 to immediately print the set self-adhesive label and attach it to the surface of the vacuum-bagged product to complete labeling. The PLC controller controls the third conveyor belt 36 to continue conveying, and conveys the bagged products that have completed vacuum labeling to the unloading port for manual material collection and boxing.
