Cover plate sticker anti-falling mechanism

A cover plate sticker anti-falling mechanism is arranged above a glue barrel of a glue rolling machine and comprises a clamping assembly clamped on a side plate of the glue barrel and a supporting plate clamped on the inner side of the glue barrel through the clamping assembly, and the end, away from the clamping assembly, of the supporting plate extends to the surface of a glue roller set above the middle of the glue barrel in the horizontal direction. The extending direction is perpendicular to the axis of the rubber roller set, and an arc-shaped face matched with the rubber roller set is arranged on the side, close to the rubber roller set, of the supporting plate. The supporting plate is arranged above the glue barrel of the glue rolling machine where the stickers pass through and located below the track where the stickers pass through, the supporting plate extends to the surface of a glue roller from the side wall of the glue barrel, the stickers fall on the supporting plate, the phenomenon that the stic
