An edge banding machine includes a machine body unit having a mounting plate, a glue-applying unit, a glue-scratching unit and a transmission unit. The glue-applying unit includes a glue container mounted fixedly on the mounting plate, a supporting member disposed fixedly and directly above the glue container and a glue-applying roller rotatably extending into the glue container. The glue-scratching unit includes a rotating shaft disposed rotatably on the supporting member, a glue-scratching plate disposed fixedly on the rotating shaft and extending toward the glue-applying roller, an adjustment rod disposed adjustably on the cover, and a connecting member connected between the adjustment rod and the rotating shaft such that movement of the adjustment rod results in rotation of the rotating shaft.
