  • Patent number: 8726963
    Abstract: An anti-vibrating tape dispenser of a carton sealing machine includes a stand erected on the carton sealing machine, a fixed shaft extended transversally from the stand, a sleeve provided for loading a tape and coaxially sheathed on the periphery of the fixed shaft, a slide mechanism installed on the stand and below the sleeve and including a slide rail slidably installed on a fixed rail, an abutting rod fixed onto the slide rail and extended in the same direction of the fixed shaft, an abutting roller sheathed on the abutting rod and abutted against the external periphery of the tape roller. As the external diameter of the tape roller varies, the abutting roller slides along the slide rail to abut against the external periphery of tape roller normally, and the abutting roller includes one-way bearings for limiting the abutting roller to rotate round the abutting rod in a direction only.
