[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an automatic corrugated cardboard packaging machine, including a packaging machine body 1, a groove 2 is provided at the top of the packaging machine body 1, and a plurality of conveying rollers 3 are provided inside the groove 2 for conveying the corrugated cardboard to be packaged forward. A packaging machine box 4 is fixedly provided at the top of the packaging machine body 1, and a sorting machine box 5 is fixedly connected to one side of the packaging machine box 4. A sorting mechanism 6 is provided inside the sorting machine box 5. The sorting mechanism 6 includes a control slot 601, a first sorting plate 602, a drive air pump 603, a hydraulic rod 604, a telescopic rod 605, a second sorting plate 606, a third sorting plate 607, and a support rod 608.

[0021] Specifically, a control slot 601 is located on one side of the sorting machine housing 5. Multiple drive air pumps 603 are fixedly installed inside the control slot 601. A hydraulic rod 604 is fixedly connected to one side of each drive air pump 603. A telescopic rod 605 is located inside the hydraulic rod 604. One end of the telescopic rod 605 passes through the control slot 601 and extends to the outside, connecting with the sorting plate structure. A second sorting plate 606 is rotatably connected to both sides of the first sorting plate 602 via a rotating shaft. A third sorting plate 607 is rotatably connected to the end of the second sorting plate 606 away from the first sorting plate 602 via a rotating shaft, thus forming a multi-level sorting structure that can be expanded or retracted. A support rod 608 is fixedly installed on one side of each of the first, second, and third sorting plates 602. The end of the support rod 608 is connected to the end of the telescopic rod 605 via a rotating shaft, thereby achieving linkage control between the sorting plate and the drive system.

[0022] In actual use, the working process of this automatic corrugated cardboard packaging machine is as follows: When the conveyor roller 3 transports the cardboard stack, which consists of multiple corrugated cardboard sheets, forward from inside the groove 2 to the preset sorting position in front of the packaging machine box 4, the sorting mechanism 6 starts to work. After the sorting mechanism 6 is started, multiple drive air pumps 603 located in the control slot 601 on one side of the sorting machine box 5 operate synchronously, providing compressed air to the hydraulic rod 604 as a power source. The hydraulic rod 604 drives the telescopic rod 605 inside it to extend outward according to the air pressure change. One end of the telescopic rod 605 passes through the control slot 601 and extends to the outside, and is connected to the support rods 608 on both sides of the first sorting plate 602 through a rotating shaft. As the telescopic rod 605 extends, the support rods 608 are pushed and drive the first sorting plate 602 to move in the set direction.

[0023] Meanwhile, the first sorting plate 602 is rotatably connected to the second sorting plate 606 on both sides via a pivot, and the end of the second sorting plate 606 away from the first sorting plate 602 is connected to the third sorting plate 607 via a pivot, forming an unfoldable linkage sorting structure. When the first sorting plate 602 moves outward under the pushing force of the support rod 608, the second sorting plate 606 and the third sorting plate 607 rotate around their respective pivots, and the overall structure gradually unfolds to form a rectangular sorting space surrounding the cardboard stack. During this process, the sorting plates in four directions (front, back, left, and right) (including the first sorting plate 602, the second sorting plate 606, and the third sorting plate 607) gradually approach the edge of the cardboard stack and apply uniform pressure to it, forcing each cardboard in the cardboard stack to align in the horizontal direction. To prevent the cardboard from deforming or being damaged due to excessive pressure, a limiting buffer device, such as a spring or rubber pad, is provided between the support rod 608 and the telescopic rod 605, which can automatically stop pushing after reaching the set pressure, ensuring the safety and stability of the sorting process.

[0024] After the four-way alignment is completed, the control system issues a reset command, driving the air pump 603 to switch the air path direction, causing the hydraulic rod 604 to retract the telescopic rod 605. At this time, the support rod 608 retracts along with the telescopic rod 605, and the first sorting plate 602, the second sorting plate 606, and the third sorting plate 607 return to their initial positions in sequence, releasing the sorting space. Subsequently, the conveyor roller 3 starts again, sending the neatly arranged cardboard stack into the packing area inside the packing machine box 4 for subsequent bundling or sealing operations. The entire sorting and packing process is coordinated and executed by the control system without manual intervention, achieving a high degree of automation. In addition, to further enhance the intelligence of the equipment, a size recognition module (such as a laser range sensor or vision system) can be integrated into the sorting machine box 5 to detect the external dimensions of the cardboard stack in real time and feed them back to the control system to dynamically adjust the output parameters of the driving air pump 603 and the stroke length of the telescopic rod 605, thereby adapting to the sorting needs of cardboard stacks of different specifications.

[0025] This utility model provides an automatic corrugated cardboard packing machine. A groove 2 is provided at the top of the packing machine body 1, and several conveying rollers 3 are arranged inside the groove 2 to achieve stable conveying of the cardboard stack. A packing machine box 4 is fixedly installed at the top of the packing machine body 1 for performing the final packing operation. Furthermore, a sorting box 5 is provided on one side of the packing machine box 4, which contains a sorting mechanism 6. This sorting mechanism 6 can align and sort the cardboard stack conveyed to the front of the packing machine box 4 in four directions (front-back, left-right), thereby significantly improving the efficiency and quality of subsequent packing operations. Specifically, the sorting mechanism 6 includes components such as a control slot 601, a first sorting plate 602, a drive air pump 603, a hydraulic rod 604, a telescopic rod 605, a second sorting plate 606, a third sorting plate 607, and a support rod 608. When the cardboard stack is sent to the front of the packing machine box 4 by the conveyor roller 3, the sorting mechanism 6 is automatically started. The drive air pump 603 drives the hydraulic rod 604 to move, causing the telescopic rod 605 to extend and retract. Through the support rod 608, the first sorting plate 602, the second sorting plate 606, and the third sorting plate 607 are pushed to rotate around the pivot, forming a sorting space surrounding the cardboard stack.

[0026] Multiple sorting plates apply uniform pressure to the cardboard stack from four directions, aligning it horizontally in all directions. This sorting process effectively eliminates misalignment, tilting, or offset during transport, ensuring a neat and uniform stack shape and providing a good foundation for subsequent packaging. After sorting, the telescopic rod 605 resets, retracting the sorting plates and releasing the sorting space. The cardboard stack is then conveyed to the packaging area for bundling or sealing. The entire sorting and packaging process is coordinated by the control system, requiring no manual intervention. It boasts advantages such as high automation, fast response, and convenient operation. In summary, this invention, through a rationally structured and highly efficient sorting mechanism 6, achieves automatic alignment of corrugated cardboard stacks of different specifications. This not only improves packaging efficiency but also significantly enhances the compactness and appearance quality of the packaged products, reducing packaging failure rates and material waste caused by cardboard misalignment. It has promising application prospects and significant promotional value.
