Bobbin paper scraper device and mouth stick forming machine

The invention relates to a bobbin paper scraper device and a mouth stick forming machine. The bobbin paper scraper device includes a mounting seat (1) and a scraper (2); the scraper (2) is fixed on the mounting seat (1); the scraper (2) is equipped with a blade portion (21); and the blade portion (21) is configured to be in contact with the surface of the bobbin paper (7) and pressed tightly, so as to roughen the surface to be glued of the bobbin paper (7) by a relative movement with the bobbin paper (7). The bobbin paper scraper device can scrape the surface of the bobbin paper to be glued through the scraper during the forming process of the mouth stick and before the bobbin paper is glued, so as to roughen the surface of the bobbin paper to be glued, which is convenient for spraying glue, can increase the absorption capacity of the bobbin paper to the glue, and is conducive to the firm bonding of the bobbin paper when forming into a cylinder during the forming process of the mouth stick; therefore, the tow
