The invention relates to a roller type adhesive tape cutting device. The roller adhesive tape cutting device comprises roller adhesive tape, an adhesive tape conveying device and a cutting device (5) and is characterized in that the roller type adhesive tape cutting device moves on the surface of an adhered object to achieve adhesion and cutting of adhesive tape, the roller adhesive tape is mounted on a roller adhesive tape mounting portion (1) in a shell A (61), and the adhesive tape conveying device is located in a shell B (62) and carries out wrinkle-free output on the adhesive tape; the cutting device (5) cuts the adhesive tape output of an outlet of the shell B (62). The roller type adhesive tape cutting device moves on the surface of the adhered object to achieve perfect connection of the adhesive tape and the adhered object without bubbles and wrinkles, output, adhesion and shearing of the adhesive tape can be repeatedly carried out through the single hand, and the adhesion efficiency and the adhesion quality are greatly improved.
