Description

Technical Field

[0001] This utility model relates to the technical field of box folding machine equipment, and in particular to a box folding machine for irregularly shaped airplane boxes. Background Technology

[0002] In the packaging industry, irregularly shaped cardboard boxes are widely used in packaging various products due to their unique structural design and excellent support performance. A common irregularly shaped cardboard box includes a main board, side panels, a front panel, and related inserts and snap-fit ​​structures. During the forming process, the main board must be placed vertically, the bottom insert must be lifted and folded to the front bottom of the main board, the side panels fold inward and are perpendicular to the main board, and the front insert of the front panel must be folded upward and tightly fitted to the inner wall of the side panel. Finally, the overall box is stably formed by the folding and snapping of the snap-fit ​​structures. This complex folding process places high demands on precision and efficiency. However, currently, the forming of such irregularly shaped cardboard boxes mainly relies on manual operation or simple mechanical equipment, resulting in low efficiency, poor product consistency, and high labor intensity. Especially in mass production, manual operation is difficult to meet the requirements of high precision and high efficiency. In addition, existing equipment usually lacks adaptability to cardboard boxes of different sizes, resulting in insufficient versatility and flexibility. Therefore, there is an urgent need for mechanical equipment that can automatically complete the above-mentioned complex folding actions to improve production efficiency, reduce labor costs, and ensure consistent forming quality. The present invention aims to solve the above problems and provide a high-efficiency, accurate and highly adaptable folding machine for irregularly shaped airplane boxes. Utility Model Content

[0005] A folding machine for irregularly shaped airplane boxes includes a carton conveying mechanism, a fastening assembly, a forming mechanism, a sliding frame, and a page-turning sheet metal, wherein:

[0006] The carton conveying mechanism is located at the front end of the equipment, and its function is to transport the pre-forming carton board to the forming mechanism. One end of the carton conveying mechanism is equipped with a fastening assembly, which is mounted on the frame and located above the forming mechanism. The fastening assembly includes a lifting plate, a pair of symmetrically arranged fastening cylinders, and a T-shaped fastening plate. The piston rods of the fastening cylinders are arranged facing each other and connected to the fastening plate. The fastening plate can move horizontally to complete the folding and fastening action of the flaps.

[0007] Furthermore, the forming mechanism includes an upper folding device and a lower discharging device. The upper folding device includes a pair of adjustable-spaced placement plates, on which a guide rail sheet is fixedly mounted. One end of the guide rail sheet is provided with a forming placement plate, which is used to horizontally support the cardboard for folding. A forming positioning suction cup is provided near the forming placement plate to adhere the cardboard during folding to ensure its stability. A main board folding sheet is fixedly mounted on one side of the forming placement plate to vertically fold the main board of the cardboard. The placement plate also includes a bottom insert lifting plate, a side plate oblique pushing sheet, and a front insert. The bottom insert lifting plate is movably connected to the placement plate in a lifting manner to lift the bottom insert; the side plate oblique pushing sheet is arranged in a V-shape to fold the side plate obliquely forward; the front insert is obliquely upward to control the oblique upward folding of the front insert.

[0008] Specifically, the lower discharge device is arranged below the upper folding device and includes a translational support plate, a lifting plate, a pusher plate, and a first cylinder.
