At present, manual cutting is replaced by mechanical means, the lunch boxes are transported by conveyor belts, and the lunch boxes are cut by cutting knives.

Lunch boxes are usually divided into two parts: the lower box body and the upper outer edge. Due to different needs of different companies, the sizes of lunch boxes produced in different batches are also different. The width of the conveyor belt of the existing lunch box conveying equipment is Fixed. When the width of the lunch box is smaller than the width of the conveyor belt, it cannot guide the lunch box. The lunch box may not be conveyed straight on the conveyor belt. When the lunch box tilts, the cutout will form an angle with the cutting knife, resulting in Oblique cuts appear on the upper edge of the cut lunch boxes, which affects the production quality. Therefore, it is necessary to develop a production device that can guide and cut lunch boxes of different sizes.
