[0002] Corrugated cardboard is a composite material composed of a layer of flat cardboard (called face paper) and an intermediate corrugated paper core layer (called corrugated paper core). It is usually used for packaging and transportation because its structure can provide good strength and buffering performance to protect the packaged items from damage;

[0003] After the corrugated cardboard is stacked by the stacking equipment, the stacked cardboard is piled on the conveyor for blanking. It is necessary for manual workers to carry the stacked cardboard before continuing to stack, which not only affects the efficiency but also increases the pressure burden on the handling personnel. Therefore, we introduce a corrugated cardboard stacking and blanking device. Summary of the Utility Model

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] A corrugated cardboard stacking and blanking device, including a conveyor 1 and a blanking tray 4. The conveyor 1 is located at the left part of the blanking tray 4. A base 5 is provided at the lower end of the blanking tray 4. A pallet 2 is placed on the conveyor 1. A plurality of cardboard pieces 3 are provided on the upper end of the pallet 2. There is no contact between the conveyor 1 and the blanking tray 4.

[0026] In this embodiment, three notches 44 are formed at the upper end of the blanking tray 4, and three sliding grooves 43 are formed at the upper end of the blanking tray 4. The three sliding grooves 43 are respectively located on one side of the three notches 44. The three notches 44 are annularly and equidistantly distributed. The three notches 44 communicate with the three sliding grooves 43 respectively. Ejecting devices 42 are fixedly connected in the three sliding grooves 43. A plurality of rollers 45 are movably connected to the inner walls of the three notches 44 through rotating shafts. Electric push rods 41 are inserted and fixedly connected to the lower groove walls of the three notches 44. The telescopic ends of the three electric push rods 41 all extend into the blanking tray 4; the ejecting device 42 includes a first motor 421. The output ends of the three first motors 421 are fixedly connected with threaded rods 422. Push plates 423 are threadedly connected to the three threaded rods 422; the first motor 421 is fixedly connected to the inner wall of the sliding groove 43. The threaded rod 422 is movably connected to the inner wall of the sliding groove 43 through a bearing. The push plate 423 is slidably connected to the sliding groove 43. The push plate 423 extends into the notch 44. The push plate 423 is located above the plurality of rollers 45; the middle part of the upper end of the base 5 protrudes outward. A connecting column 53 is movably connected to the middle part of the upper end of the base 5 through a bearing. A first gear 51 is fixedly connected to the outer surface of the connecting column 53. A second motor 54 is fixedly connected to the right part of the upper end of the base 5. The output end of the second motor 54 is fixedly connected with a second gear 52; the second gear 52 is meshed with the connecting column 53; the connecting column 53 is fixedly connected to the lower end of the blanking tray 4.

[0027] Through the above solution: When the cardboard piece 3 enters the blanking tray 4, start the second motor 54 to work. The second motor 54 drives the second gear 52, the connecting column 53 and the first gear 51 to rotate. The connecting column 53 drives the blanking tray 4 to rotate. The rotation of the blanking tray 4 drives the cardboard piece 3 in the notch 44 above it to rotate and move. Since there are three notches 44 formed on the blanking tray 4, the continuity of stacking can be achieved, and the blanking efficiency is improved.

[0028] It should be noted that the present invention is a corrugated cardboard stacking unloading device. During use, a discharge tray 4 is provided with three integrated notches 44 and equipped with a number of rollers 45 to enhance the smooth sliding of the cardboard pieces 3. When the conveyor 1 accurately transports the cardboard pieces 3 and the tray 2 to the discharge tray 4, the cardboard pieces 3 slide smoothly into the notches 44 with the assistance of gravity and the rollers 45. Subsequently, the electric push rod 41 built into the notch 44 is activated, and its telescopic end quickly extends to firmly limit the position of the tray 2. The No. 2 motor 54 is started to drive the No. 2 gear 52 to rotate, and through the meshing action of the gears, the No. 1 gear 51 and the connecting column 53 connected thereto are driven to rotate, thereby realizing the overall rotation of the discharge tray 4. This rotational motion causes the tray 2 and cardboard pieces 3 to move smoothly until they reach the next slot 44 aligned with the conveyor 1. The unloading tray 4 stops rotating, and the No. 1 motor 421 starts, driving the threaded rod 422 to rotate. Using the principle of thread transmission, the push plate 423 in the chute 43 moves slowly and steadily forward until the tray 2 in the slot 44 is smoothly ejected. Before ejection, the electric push rod 41 retracts, releasing the position limit on the tray 2. By repeating these steps, the automated and continuous stacking and unloading of cardboard is achieved, significantly improving overall operation efficiency and precision.
