Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box stacking technology, and specifically to a cardboard box stacking device. Background Technology
[0002] In the home furnishing manufacturing industry, after home furnishing products are carefully manufactured and ready to leave the factory, the packaging process before shipment is particularly important to effectively prevent various bumps, frictions, or damages that may occur during subsequent transportation, ensuring that the products arrive at consumers intact. Cardboard boxes, as a widely used packaging material, are primarily made from wood fibers and various waste paper. This not only gives cardboard boxes excellent cushioning and shock absorption capabilities, effectively protecting products from damage caused by collisions, compression, and other external forces, but also significantly reduces packaging costs, saving manufacturers considerable expenses. Furthermore, cardboard boxes are flexible and diverse in their processing; through die-cutting, folding, and other processes, they can be made into different shapes and sizes to meet the packaging needs of various home furnishing products. More importantly, cardboard boxes are a recyclable material that can be easily recycled and reused after use. Even if they enter the natural environment, they can degrade in a relatively short time, greatly reducing the burden on the environment. This environmentally friendly characteristic perfectly aligns with the high importance and strict requirements of modern society for green environmental protection. For this reason, more and more regions and manufacturers are actively responding and vigorously promoting the widespread application of cardboard box packaging.
[0003] For home furnishing processing, cardboard boxes first need to be printed with product information, brand logos, and other details. Then, conveyor belts and rollers are used to sequentially place multiple boxes into the packaging area, allowing them to be stacked layer by layer in preparation for subsequent home furnishing product packaging. In practice, if the conveyor mechanism directly places multiple boxes into the packaging area, the stacked boxes are difficult to keep neatly arranged, leading to tilting, collapse, and other problems, thus affecting the packaging process. To solve this problem, a frame with a U-shaped internal structure is typically used to limit the boxes placed into the packaging area, ensuring they are neatly stacked. However, removing cartons from either the bottom or top of the rack presents certain difficulties. Removing cartons from the top requires feeding them into the rack from the top, as the discharge end of the transmission mechanism is located above the rack. This means the transmission mechanism must be shut down before removal, interrupting continuous conveying and reducing efficiency. Conversely, removing cartons from the bottom is also cumbersome due to the multiple cartons stacked above them. Furthermore, the single input method of only allowing cartons into the rack negatively impacts stacking efficiency, limiting speed and flexibility. Therefore, the existing carton stacking system has shortcomings and urgently needs technical improvements to facilitate carton removal and support multi-path stacking, thereby enhancing stacking effectiveness. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a carton stacking device that facilitates the removal of cartons and supports multi-path stacking of cartons, thereby overcoming the deficiencies in existing technologies.
[0005] The technical solution adopted by this utility model is as follows: a cardboard box stacking device, including a frame with an inner cavity of U-shape, a support frame with an inner cavity of U-shape above the frame, a plurality of fixing rods at the top of the frame, the bottom ends of the fixing rods respectively installed at the edge of the frame, a fixing frame on each fixing rod, the bottom of the fixing frame installed at the top of the fixing rod, and a fixing leg movably fitted on the top of the fixing frame, the fixing leg being installed on the support frame; two fixing shafts are rotatably mounted on the frame, the two fixing shafts being located on both sides of the frame, and fixing plates and baffles are respectively installed on the fixing shafts. One end of the baffle and one end of the fixed plate are both mounted on a fixed shaft. A first telescopic cylinder is provided between the fixed plate and the frame. One end of the first telescopic cylinder is hinged to the other end of the fixed plate, and the other end of the first telescopic cylinder is hinged to the frame. Two support shafts are provided in the middle of the bracket. The two support shafts are rotatably mounted on both sides of the bracket. A support plate and a cross plate are respectively provided on the support shafts. One end of the cross plate and one end of the support plate are both mounted on the support shaft. A second telescopic cylinder is provided between the support plate and the bracket. One end of the second telescopic cylinder is hinged to the other end of the support plate, and the other end of the second telescopic cylinder is hinged to the bracket.
[0006] Preferably, fixing blocks are provided on both sides of the fixing shaft, the top of the fixing blocks are installed on the bottom of the frame, the fixing blocks are provided with fixing holes, the fixing shaft is rotatably fitted into the fixing holes, one side of the baffle is located below the inner cavity of the frame, a fixing frame is provided below the fixing blocks, and the bottom of the fixing frame is installed on the top of the fixing blocks.
[0007] Preferably, a plurality of first stop arms are vertically arranged on one side of the bracket, and a plurality of first support arms are vertically arranged on the other side of the bracket. The first support arms and the first stop arms are both integrally formed with the bracket. The top of the first stop arm is located above the first support arm. Both the first support arm and the first stop arm have sleeve holes, and the support shaft is rotatably fitted into the sleeve holes. The top of the first support arm has a first guide groove that is inclined. The height of the first guide groove gradually increases along the direction close to the first stop arm, and the bottom of the first support arm is located above the fixed leg.
[0008] Preferably, a second stop arm is provided below the first stop arm and a second support arm is provided below the first support arm. Both the second support arm and the second stop arm are integral with the frame. The top of the second stop arm is not higher than the top of the fixed rod. The top of the second stop arm is located above the second support arm. A second guide groove is obliquely opened at the top of the second support arm. The groove height of the second guide groove gradually increases along the direction close to the second stop arm.
[0009] Preferably, one end of the horizontal plate is provided with a ring, and one end of the horizontal plate is installed on the outer wall of the ring. The ring is movably fitted on the support shaft, and the diameter of the support shaft matches the inner diameter of the ring. A threaded hole is opened on the side of the ring away from the horizontal plate, and a bolt is threaded in the threaded hole. The ring is clamped and fixed on the support shaft by the bolt.
[0010] Preferably, the frame is provided with two third telescopic cylinders, both of which are located above the fixed shafts and at both ends of the frame. The telescopic direction of both third telescopic cylinders is towards the middle of the frame. Each telescopic end of the two third telescopic cylinders is provided with a push plate, the bottom of which is located between the two fixed shafts and the top of which is located below the fixed frame.
[0011] The beneficial effects of this utility model are as follows: First, by setting a fixed frame, the fixed legs can be constrained on the fixed rod, so that the bracket can be detachably assembled on the top of the frame. Thus, the frame and the bracket can be used separately, or they can be assembled together. The fixed legs and the fixed rod create a stacking and feeding space for the frame, allowing cartons to be fed into the frame through the stacking and feeding space between the fixed legs and the fixed rod. Cartons can also be fed into the bracket from above, thus providing multiple stacking paths for cartons and improving the stacking efficiency of cartons. Furthermore, this invention, through the first telescopic cylinder, can drive the fixed shaft and baffle to rotate around the central axis of the fixed shaft under the transmission of the fixed plate, so that the baffle can support the cartons falling into the frame and stack them in the frame. Through the second telescopic cylinder, can drive the support shaft and cross plate to rotate, so that the cross plate can support the cartons falling into the support and stack them in the support. Therefore, by controlling the first and second telescopic cylinders, the cartons can fall out of the frame or support for packaging operations.
[0012] Secondly, this invention uses a fixing block to rotatably mount the fixing shaft below the frame, creating a stacking space for the cartons. A fixing frame collects cartons falling from the frame. Furthermore, the invention uses a first stop arm, a first support arm, a second stop arm, and a second support arm to limit the cartons falling into the frame and support, ensuring effective stacking. A first guide groove on the first support arm and a second guide groove on the second support arm guide the cartons into the inner cavity of the frame or support.
[0013] Furthermore, this invention uses a ring to assemble the horizontal plate onto the support shaft, and bolts to clamp and fix the ring onto the support shaft, allowing adjustment of the horizontal plate's position on the support shaft to support the cartons falling into the bracket. Moreover, this invention uses a third telescopic cylinder and a push plate to push and press the cartons stacked on the frame, ensuring they are neatly placed on the baffle.

[0019] like Figures 1 to 5As shown, a cardboard box stacking device includes a frame 1 with an inner cavity of a U-shape. A support 2 with an inner cavity of a U-shape is mounted above the frame 1. Several fixing rods 3 are mounted at the top of the frame 1, with their bottom ends respectively installed at the edges of the frame 1. Each fixing rod 3 has a fixing frame 4, the bottom of which is installed at the top of the fixing rod 3. A fixing leg 5 is movably fitted onto the top of the fixing frame 4. The fixing leg 5 is mounted on the support 2, and its shape matches the inner cavity shape of the fixing frame. The bottom end of the fixing leg 5 contacts the top end of the fixing rod 3, thereby assembling the support 2 onto the frame 1. The device utilizes the length and fixing... The length of rod 3 creates a stacking and feeding space for frame 1. Two conveying mechanisms, such as two conveyor belts, allow the cartons to be stacked to be transported separately into frame 1 and support 2, improving stacking efficiency. Furthermore, by removing support 2 from frame 1, support 2 and frame 1 can be used independently to stack cartons, meeting diverse stacking needs. Two fixed shafts 6 are rotatably mounted on frame 1, located on opposite sides of frame 1. Fixed shafts 7 and baffles 8 are mounted on fixed shafts 6, with one end of baffle 8 and one end of fixed plate 7 mounted on the fixed shafts 6. A first extension is provided between fixed plate 7 and frame 1. The first telescopic cylinder 9 has one end hinged to the other end of the fixed plate 7 and the other end hinged to the frame 1. By controlling the telescopic cylinder 9 to extend or retract, the fixed plate 7 can be rotated, thereby pushing the fixed shaft 6 and the baffle 8 to rotate. The baffle 8 is used to support the falling cartons, thus stacking the cartons inside the frame 1. The support 2 has two support shafts 10 in the middle, which are rotatably mounted on both sides of the support 2. Support plates 11 and horizontal plates 12 are respectively mounted on the support shafts 10. One end of the horizontal plate 12 and one end of the support plate 11 are mounted on the support shafts 10. The support plate 11 is connected to the support 2. A second telescopic cylinder 13 is provided, with one end of the second telescopic cylinder 13 hinged to the other end of the support plate 11 and the other end of the second telescopic cylinder 13 hinged to the bracket 2. By controlling the extension and retraction of the second telescopic cylinder 13, the support plate 11 can be driven to rotate, thereby driving the support shaft 10 and the horizontal plate 12 to rotate, so that the horizontal plate 12 can be used to support the falling cartons, thereby stacking the cartons in the bracket 2. The horizontal plate 12 is located above the fixed leg 5 to avoid the horizontal plate 12 interfering with the cartons conveyed into the frame 1. The cross-sectional shape of the inner cavity of the bracket 2 matches the cross-sectional shape of the inner cavity of the frame 1 so that the cartons stacked in the bracket 2 fall into the frame 1.
[0020] In this embodiment, fixing blocks 14 are respectively provided on both sides of the fixing shaft 6. The top of the fixing block 14 is installed on the bottom of the frame 1. The fixing block 14 has a fixing hole. The fixing shaft 6 is rotatably fitted into the fixing hole. One side of the baffle 8 is located below the inner cavity of the frame 1. A bearing is provided in the fixing hole. The fixing shaft 6 is rotatably fitted into the fixing hole through the bearing so that the fixing shaft 6 can be rotatably assembled below the frame 1 so that the frame 1 can create a stacking space for cartons. A fixing frame 15 is provided below the fixing block 14. The bottom end of the fixing frame 15 is installed on the top of the fixing block 14 so that when the fixing shaft 6 rotates, when the end of the baffle 8 away from the fixing shaft 6 rotates to below the fixing shaft 6, the cartons stacked in the frame 1 can be discharged from the frame 1 so that the cartons falling out of the frame 1 can be collected by the fixing frame 15. An opening is provided on one side of the fixing frame 15 so that the cartons falling out of the frame 1 can be taken out through the opening.
[0021] Specifically, a plurality of first stop arms 16 are vertically arranged on one side of the bracket 2, and a plurality of first support arms 17 are vertically arranged on the other side of the bracket 2. Both the first support arms 17 and the first stop arms 16 are integrally formed with the bracket 2, allowing the first stop arms 16 and the first support arms 17 to limit the movement of cartons falling into the bracket 2, ensuring the stacking effect of the cartons. The top of the first stop arm 16 is located above the first support arm 17. Both the first support arm 17 and the first stop arm 16 have sleeve holes, into which the support shaft 10 is rotatably fitted. A bearing is installed within the sleeve hole, and the support shaft 10 is rotatably fitted through the bearing. The set is rotated and mounted on the first support arm 17 or the first stop arm 16, thereby supporting the support shaft 10 using the first support arm 17 or the first stop arm 16 to improve the stability of the support shaft 10. The top of the first support arm 17 is provided with a first guide groove 18 at an angle. The height of the first guide groove 18 gradually increases along the direction close to the first stop arm 16, so as to facilitate guiding the carton from outside the first support arm 17 between the first support arm 17 and the first stop arm 16. The bottom end of the first support arm 17 is located above the fixed leg 5 to avoid the first support arm 17 interfering with the carton being conveyed into the frame 1.
[0022] Please refer again to 1 to 4. A second stop arm 19 is provided below the first stop arm 16, and a second support arm 20 is provided below the first support arm 17. Both the second support arm 20 and the second stop arm 19 are integral with the frame 1. The second stop arm 19 and the second support arm 20 are used to limit the carton falling into the frame 1 to ensure the stacking effect of the carton. The top of the second stop arm 19 is not higher than the top of the fixing rod 3 to avoid the second stop arm 19 from colliding with the bracket 2. The top of the second stop arm 19 is located above the second support arm 20. The top of the second support arm 20 is inclinedly provided with a second guide groove 21. The height of the second guide groove 21 gradually increases along the direction close to the second stop arm 19, so as to facilitate guiding the carton from outside the second support arm 20 between the second support arm 20 and the second stop arm 19.
[0023] In this embodiment, a ring 22 is provided at one end of the horizontal plate 12. The horizontal plate 12 is installed on the outer wall of the ring 22. The ring 22 is movably fitted on the support shaft 10. The diameter of the support shaft 10 matches the inner diameter of the ring 22. A threaded hole is provided on the side of the ring 22 away from the horizontal plate 12. A bolt 23 is threaded in the threaded hole. The ring 22 is clamped and fixed on the support shaft 10 by the bolt 23 so as to adjust the position of the horizontal plate 12.
[0024] Specifically, the frame 1 is equipped with two third telescopic cylinders 24, both of which are located above the fixed shaft 6 and on the frame 1. The telescopic direction of the two third telescopic cylinders 24 is towards the middle of the frame 1. Each telescopic end of the two third telescopic cylinders 24 is equipped with a push plate 25. The bottom of the push plate 25 is located between the two fixed shafts 6, and the top of the push plate 25 is located below the fixed frame 4. This allows the push plate 25 to be driven to push the cartons stacked on the frame 1 by controlling the telescopic movement of the third telescopic cylinders 24, so that the cartons stacked on the frame 1 can be neatly placed on the baffle 8.
[0025] It should be noted that both the frame 1 and the bracket 2 are equipped with support rods. One side of the support rod is mounted on the frame 1 and the bracket 2, and the other side of the support rod is located outside the frame 1 or the bracket 2. One end of the first telescopic cylinder 9 or the second telescopic cylinder 13 is hinged to the other side of the support rod. The extension direction of the fixed plate 7 is perpendicular to the extension direction of the baffle 8, so that the first telescopic cylinder 9 can be used to push the fixed plate 7 to rotate. The extension direction of the support plate 11 is parallel to the extension direction of the cross plate 12, so that the second telescopic cylinder 13 can be used to push the support plate 11 to rotate.
[0026] The instructions for using this product are as follows: Figures 1 to 5As shown, firstly, forklifts, cranes, and other handling equipment are used to move the product to the packaging area. Next, the first telescopic cylinder 9, the second telescopic cylinder 13, and the third telescopic cylinder 24 are connected to the pump body via corresponding valves. This allows the valves to control the extension and retraction of the first telescopic cylinder 9, the second telescopic cylinder 13, and the third telescopic cylinder 24. Simultaneously, the output end of the conveyor belt, rollers, and other transmission mechanisms needs to be moved to a position directly above the first support arm 17 or the second support arm 20, so that the cartons can be smoothly fed into the internal space of the support 2 and the frame 1. Then, by controlling the extension and retraction of the first telescopic cylinder 9 and the second telescopic cylinder 13, one side of the horizontal plate 12 is positioned inside the support 2, and one side of the baffle 8 is positioned below the inner cavity of the support 2, facilitating the stacking of cartons fed into the support 2 or the frame 1. Finally, by periodically controlling the extension and retraction of the first telescopic cylinder 9, the second telescopic cylinder 13, and the third telescopic cylinder 24, the cartons are lowered onto the fixed frame 15, allowing operators to easily retrieve the cartons and efficiently carry out subsequent packaging operations, ensuring a smooth and efficient packaging process.
[0027] In this embodiment, by setting the fixed frame 4, the fixed leg 5 can be constrained to the fixed rod 3, so that the bracket 2 can be detachably installed on the top of the frame 1. Thus, the frame 1 and the bracket 2 can be used separately, or the frame 1 and the bracket 2 can be assembled together for use. The fixed leg 5 and the fixed rod 3 create a stacking and feeding space for the frame 1, so that cartons can be put into the frame 1 through the stacking and feeding space created between the fixed leg 5 and the fixed rod 3. Cartons can also be put into the bracket 2 from above, so as to provide multiple stacking paths for cartons, thereby improving the stacking efficiency of cartons. Furthermore, this utility model, through the first telescopic cylinder 9, under the transmission of the fixed plate 7, can drive the fixed shaft 6 and the baffle 8 to rotate around the central axis of the fixed shaft 6, so that the baffle 8 can support the carton falling into the frame 1, allowing the carton to be stacked in the frame 1. Through the second telescopic cylinder 13, it can drive the support shaft 10 and the horizontal plate 12 to rotate, so that the horizontal plate 12 can support the carton falling into the bracket 2, allowing the carton to be stacked in the bracket 2. Therefore, by controlling the first telescopic cylinder 9 and the second telescopic cylinder 13, the carton can fall out from the frame 1 or the bracket 2, so that the carton can be taken out for packaging operations.
[0028] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
