The invention discloses a box pasting and folding
machine with automatic paper correcting and window pasting functions. The box pasting and folding
machine comprises a
machine frame, a paper rolling shaft, a glue
barrel and a paper cutter. The glue
barrel can slide up and down in the vertical direction of the machine frame, detachable glue distributing wheels are arranged in the glue
barrel, and pawls abut against the outer contour faces of the glue distributing wheels. A shell type moving bar is arranged on the part, located in front of the glue barrel, of the machine frame, and at least a row of outer air suction holes communicated with a shell cavity is formed in the outer wall of the moving bar in the axial direction. An air suction barrel is arranged in the moving bar shell cavity in sealed and sliding
modes, and an extraction hole communicated with an inner cavity of the air suction barrel is formed in the shaft body of an extending section and communicated with an air extractor. A row of inner air suction holes is formed in the wall of the air suction barrel. A sliding frame is arranged on a sliding rail in a sliding mode. A sliding table is connected to a fixed guide rail in a sliding mode, a movable holding plate and a fixed holding plate are arranged on the sliding table in parallel, and a pair of paper conveying press rollers is correspondingly arranged behind the paper cutter. According to the box pasting and folding machine, ground paper can be quickly corrected, the glue distributing amount is sufficient, glue lines are uniform, and the box pasting quality is good.
