Carton packaging device capable of automatically gluing

The carton packaging device comprises a workbench, a feeding table is fixedly installed on the upper portion of the workbench, driving boxes are rotatably installed on the left side and the right side of the workbench, hydraulic push rods are arranged on the upper portions of the driving boxes, and connecting plates are installed at the top ends of the hydraulic push rods. A limiting plate is arranged on the upper portion of the feeding table, the two ends of the limiting plate are rotationally connected with the connecting plates, and a feeding port is formed in the middle of the limiting plate. The motor drives the positioning block to rotate so as to control the driving box and the hydraulic push rod to rotate, so that it is guaranteed that the limiting plate can conduct circular motion work, and due to limitation of the hydraulic push rod, the limiting plate is attached to the outer surface of the carton to work; and meanwhile, due to the rolling shaft rotationally installed at the bottom of the limiting
