The utility model relates to the technical field of conveying devices, and discloses a conveying device for producing and processing a plastic box, which solves the problems that the precision is not high and the plastic box is difficult to limit in a central area due to the fact that a positioning plate is independently adjusted through two hand wheels in the existing conveying device. Supporting legs are fixedly mounted at four corners of the bottom of the mounting frame, mounting plates are fixedly mounted on the upper portions of the two sides of the mounting frame, shaft seats are fixedly mounted at the tops of the mounting plates, limiting rods are rotatably mounted at the tops of the shaft seats, and limiting strips are fixedly mounted on the sides, close to each other, of the two limiting rods. Sliding grooves are formed in the sides, away from each other, of the two limiting rods, and synchronous limiting assemblies are arranged between the two sides and the bottom of the mounting frame. According to the conveying device, the two limiting strips can be synchronously adjusted, so that it can be guaranteed that the plastic box is limited in the middle area, and the using effect is very good.
