[0002] RFID smart tags are a type of electronic tags with a long service life and can be quickly scanned by electronic devices, making it easy to take inventory. Currently, some labels on clothing have already adopted RFID smart tags; and the RFID smart tags for clothing need to be wrapped on a bonding tape printed with product information; the material tape with the smart tags needs to be cut to make it an independent smart tag.

[0003] For example, Chinese patent CN216992059U discloses a positioning and cutting device for the production of electronic tags. The device drives the cutter to cut through the transmission component to achieve cutting of the material strip. By adjusting the speed of the motor, the device can adapt to electronic tags of various sizes.

[0018] The utility model has the following technical effects:

[0019] 1.
