  • Patent number: 12698122
    Abstract: The present disclosure provides a bench-top label dispenser for acousto-magnetic (AM) anti-theft labels. The bench-top label dispenser includes a housing, and a feeding mechanism, a guide mechanism, a tension traction mechanism, and a control mechanism that are arranged on the housing, where an AM anti-theft label release liner on the feeding mechanism is connected to the tension traction mechanism through the guide mechanism; the tension traction mechanism is controlled by the control mechanism to pull the AM anti-theft label release liner; the housing is provided with a label sensing module electrically connected to the control mechanism; the guide mechanism includes a label peeling plate; and labels located at a tail end of the label peeling plate are within a sensing range of the label sensing module. The present disclosure can effectively improve the efficiency of peeling and labeling, greatly reduce the labor intensity, and reduce the labeling cost.

  • Publication number: 20250187777
    Abstract: The present disclosure provides a hand-held labeling machine for acousto-magnetic (AM) anti-theft labels, and an AM antitheft label roll. The hand-held labeling machine includes a shell, a label feeding mechanism, a labeling mechanism, a take-up mechanism, and a limit and detection assembly, wherein the label feeding mechanism is configured to convey AM anti-theft labels; the labeling mechanism includes a label stripping head and a roller; the label stripping head is fixedly connected to the shell, and abuts against a release liner; the roller is provided above the label stripping head, and is rotatably connected to the shell; the roller abuts against the AM anti-theft label; the take-up mechanism includes a take-up spool rotatably connected to the shell and a drive assembly; and the drive assembly is configured to drive the take-up spool to rotate. The present disclosure can realize easy and stable labeling of the AM anti-theft labels.
