Hand-held labeling machine for acousto-magnetic (AM) anti-theft labels, and am anti-theft label roll

A hand-held labeling machine for acousto-magnetic (AM) anti-theft labels, comprising a shell, and a label feeding mechanism, a labeling mechanism, a take-up mechanism and a limit and detection assembly that are arranged on the shell, wherein

• the label feeding mechanism is configured to convey AM anti-theft labels that are attached to a release liner;
• the labeling mechanism comprises a label stripping head and a roller;
• the label stripping head is fixedly connected to the shell, and abuts against the release liner;
• the roller is provided above the label stripping head, and is rotatably connected to the shell;
• and the roller abuts against the AM anti-theft label;
• the take-up mechanism comprises a take-up spool and a drive assembly;
• the take-up spool is rotatably connected to the shell;
• the drive assembly is configured to drive the take-up spool to rotate;
• an end of the release liner away from the label feeding mechanism passes through the limit and detection assembly and the label stripping head, and is fixed to the take-up spool;
• the limit and detection assembly is configured to detect a position of the AM anti-theft label and send a stop labeling signal to the drive assembly;
• and the drive assembly is configured to receive the stop labeling signal and stop driving the take-up spool to rotate,
• wherein the limit and detection assembly comprises a position detection module, a signal sending module, and a clamping portion;
• the clamping portion is provided on the shell;
• the position detection module and the signal sending module are respectively provided on two sides of the clamping portion;
• and the AM anti-theft label and the release liner pass through the clamping portion;
• and
• the position detection module is in communication connection with the signal sending module, and is provided above the AM anti-theft label;
• the position detection module is configured to detect the position of the AM anti-theft label and send a detection signal to the signal sending module;
• and the signal sending module is configured to receive the detection signal and send the stop labeling signal to the drive assembly.
