The application discloses a handheld labeler for an acousto-magnetic anti-theft
label and an acousto-magnetic
label roll, and the handheld labeler comprises a shell, a
label feeding mechanism, a label sticking mechanism, a label collecting mechanism and a position detection
assembly; the label feeding mechanism is used for conveying the acousto-magnetic label; the label sticking mechanism comprises a label stripping head and a roller, the label stripping head is fixedly connected to the shell, the label stripping head is in
abutment with a bottom tape, the roller is arranged above the label stripping head, the roller is rotatably connected to the shell, and the roller is in
abutment with the acousto-magnetic label; the label collecting mechanism comprises a label collecting shaft and a driving
assembly, the label collecting shaft is rotatably connected to the shell, the driving
assembly is used for driving the label collecting shaft to rotate, one end of the bottom tape, which is away from the label feeding mechanism, passes through the position detection assembly, the label stripping head and is fixed to the label collecting shaft, the position detection assembly is used for detecting the position of the acousto-magnetic label and sending a label sticking stopping
signal to the driving assembly, and the driving assembly is used for receiving the label sticking stopping
signal and stopping driving the label collecting shaft to rotate. The application can realize convenient and stable label sticking of the acousto-magnetic label.
