  • Patent number: 12098047
    Abstract: For the defects that manual adhesive tape pasting is low in efficiency and high in cost, and it is difficult to automatically paste adhesive tapes at specified positions of inner and outer surfaces of an item according to a certain length through a handheld box sealer and an adhesive tape seal pasting mechanism, a cantilever type plane automatic adhesive tape pasting device is invented. A liftable two-stage telescopic cantilever adhesive tape pasting head structure, a roller type automatic adhesive tape feeding structure, an adjustable fixed-length cutting structure and a roller type pasting structure are adopted for the device to achieve the automatic adhesive tape pasting on inner and outer side planes of an item. After the item needing adhesive tape pasting is positioned, the pasting process is completely automatically conducted without manual participation, the labor intensity is reduced, the labor efficiency is improved.
