Abstract

This utility model relates to the field of cardboard box inspection technology, specifically to a cardboard box forming accuracy inspection device, including a frame; the frame is equipped with a transmission plate; a lower paper pressing assembly is provided at the bottom of the transmission plate; an upper paper pressing assembly is provided at the top of the transmission plate; the lower paper pressing assembly includes a lower paper pressing roller and multiple lower paper pressing wheels; the lower paper pressing roller is rotatably mounted on the frame; the upper paper pressing assembly includes an upper paper pressing seat, an upper paper pressing roller, and multiple upper paper pressing wheels; the upper paper pressing roller is fixedly mounted on the upper paper pressing seat; the upper paper pressing seat is equipped with a line scan camera. This utility model drives the lower paper pressing roller to rotate, which in turn drives the lower paper pressing wheels to rotate. The cardboard presses against the upper and lower paper pressing wheels, thus moving the cardboard forward. When the cardboard moves to the line scan camera, the line scan camera scans the cardboard features and analyzes the relevant dimensions of the cardboard's feeding accuracy, printing accuracy, slotting accuracy, and registration accuracy, realizing automatic cardboard inspection and improving inspection efficiency and accuracy.
