▎ 摘　　要

NOVELTY - The device has a pressure sensor to detect a pressure value generated by a scraper to a gravure roller. An elastic portion generates elastic deformation, which has a threshold value, where an elastic deformation amount threshold value of the elastic portion is related to a pressure value such that the pressure value is changed in certain range. A floating piece comprises a floating portion, a sliding portion and the elastic portion. Ends of the floating portions are respectively connected with the scraper and the sliding portions. The sliding portion slides along an inner wall of a shell. The floating portion elastically deforms along direction vertical to the elastic portion. The floating portion and the elastic portion provide elastic floating in two directions for the scraper. USE - Graphene radio-frequency identification (RFID) label gravure printing device. ADVANTAGE - The device can adjust contact angle of the scraper and the gravure roller, and can adjust and read contact pressure of the scraper and the gravure roller so as to ensure gravure roller surface redundant graphene slurry scraping cleaning effect. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene RFID label gravure printing device.
