The invention discloses a safety warning line adhesive tape pasting device. The safety warning line adhesive tape pasting device is composed of a transmission fixing mechanism, a stripping mechanism, a cutting mechanism, a rolling pressing and pasting mechanism and an adhesive tape adhesive face pushing mechanism; the transmission fixing mechanism is composed of two pairs of roller sets with rotating axes in the horizontal direction, the stripping mechanism is at least composed of a set of stripping rollers with rotating axes in the horizontal direction, the cutting mechanism comprises a cutting platform and a cutting knife, and a body of the rolling pressing and pasting mechanism is a pressing and pasting roller. After adhesive tape enters the gap between two downstream rollers from the gap between two upstream rollers, an adhesive face protective layer is separated from an adhesive tape adhesive face and enters the gap between the two stripping rollers, the back face, without adhesive, of the adhesive tape adhesive face layer falls on the cutting platform, the cutting knife can move on the cutting platform, the cutting edge is perpendicular to the adhesive tape, and the adhesive face of the adhesive tape adhesive face layer faces upward and is pushed and pulled to the underneath in front of the pressing and pasting roller through the adhesive tape adhesive face pushing mechanism. By means of the device, the adhesive tape can be automatically measured, cut and pasted, the pasting effect is good, and pasting efficiency is high.
