Description

Technical Field

[0001] This utility model relates to the field of folding cardboard stacking technology, specifically to a folding cardboard lifting platform. Background Technology

[0002] The core solution of folding cardboard is to fold a flat, continuous sheet of cardboard into a neat, vertical stack. This makes cardboard, which was previously difficult to transport and store, much easier to transport and store, allowing customers to use it as needed. Folding cardboard is increasingly widely used in the packaging industry, primarily to meet customized needs such as furniture and complete kitchens. With the continuous increase in customization and personalization demands, the equipment for producing continuous cardboard also needs to be upgraded accordingly.

[0003] Folding cardboard equipment includes a conveying unit, a swaying unit, and a stacking unit. The stacking unit is used for stacking folded cardboard. Folding cardboard equipment is usually quite tall, and once a certain height of folded cardboard is stacked, it becomes difficult to move the stacked cardboard, affecting the efficiency of folding cardboard production and packaging. Utility Model Content

[0004] To address the shortcomings of existing technologies, a folding cardboard lifting platform is proposed. This platform solves the problem that existing folding cardboard equipment is typically quite tall, making it difficult to move stacked folding cardboard after a certain height has been stacked, thus affecting the efficiency of folding cardboard production and packaging.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A folding cardboard lifting platform includes a support platform for supporting folding cardboard. The height of the support platform is adjustable. By adjusting the reciprocating motion of the support platform between the loading and unloading points, the height of the support platform is changed, thereby driving the folding cardboard carried on the support platform to achieve lifting and transportation.

[0007] Furthermore, it also includes an adjustment component for driving the support platform to move along the height direction. The adjustment component includes a support frame for limiting the movement trajectory of the support platform, and the support platform moves along the extension direction of the support frame to achieve lifting and lowering.

[0008] Furthermore, the adjustment component also includes a drive chain, which is rotatably connected to the support frame via a sprocket. The support platform is fixedly connected to the drive chain to reciprocate in the height direction following the rotation of the drive chain, thereby achieving lifting and lowering.

[0009] Furthermore, a first slider is provided on each side of the support platform. The first slider is slidably connected in a first slide rail on the side of the support frame closer to the support platform. When the support platform moves along the support frame with the drive chain, the first slider slides along the first slide rail to guide the support platform and provide support and limit.

[0010] Furthermore, a feeding conveyor belt is provided on the support platform. After the support platform drives the folded cardboard down to the feeding point, the feeding conveyor belt rotates to drive the folded cardboard away from the support platform to achieve feeding.

[0011] Furthermore, it also includes a buffer platform, which is located above the support platform. The distance between the buffer platform and the feeding point is adjustable. The buffer platform is close to the feeding point and supports the folded cardboard so that the support platform can drive the folded cardboard to descend and unload the material.

[0012] Furthermore, the buffer platform is slidably connected to the sliding frame, and the buffer platform slides back and forth along the sliding frame to receive the folded cardboard near the loading point to facilitate the unloading of the support platform, or to receive the folded cardboard away from the loading point to facilitate the raised support platform receiving the folded cardboard.

[0013] Furthermore, the sliding frame is provided with a first rack, which meshes with a first gear. There are two first gears, which are respectively fixed at both ends of a first rotating shaft. The first rotating shaft is rotatably connected to a connecting plate. The two sides of the buffer platform are slidably connected to the sliding frame through the connecting plate.

[0014] Furthermore, the buffer platform is slidably connected to the connecting plate to achieve lifting and lowering along the height direction, which facilitates adjustment of the distance between it and the support platform, thereby allowing the folded cardboard on the buffer platform to fall smoothly onto the support platform to achieve buffering.

[0015] Furthermore, the buffer platform is provided with sliding plates on both sides, and the sliding plates are slidably connected to the guide rails on the connecting plate. A second rack is provided on the side of the sliding plate away from the buffer platform. The second rack is meshed with a second gear, and the second gear is rotatably connected to the connecting plate through a second rotating shaft.

[0016] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0017] This application sets up a support platform to cooperate with the folding cardboard equipment. The platform receives and carries the folding cardboard to achieve stacking. After the folding cardboard is stacked to a certain height, the support platform drives the folding cardboard to descend along the height direction so that the stack of folding cardboard can fall to the ground for unloading. The reciprocating motion of the support platform improves the efficiency of transporting folding cardboard. At the same time, it can better cooperate with other mechanisms of the folding cardboard equipment to avoid the impact of height factors on the unloading and stacking of folding cardboard, thereby improving the overall working efficiency of the folding cardboard equipment.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Terms such as "upper," "lower," "left," "right," and "top" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0023] like Figures 1 to 2 As shown, a folding cardboard lifting platform includes a support platform 1 for supporting folding cardboard. The height of the support platform 1 is adjustable. By adjusting the reciprocating motion of the support platform 1 between the loading and unloading points, the height of the support platform 1 is changed, thereby driving the folding cardboard carried on the support platform 1 to achieve lifting and transportation.

[0024] By setting up a support platform 1 in conjunction with the folding cardboard equipment, the support platform 1 receives and carries the folding cardboard to achieve stacking. After the folding cardboard is stacked to a certain height, the support platform 1 drives the folding cardboard to descend along the height direction so that the stack of folding cardboard can fall to the ground for unloading. The reciprocating motion of the support platform 1 improves the efficiency of transporting folding cardboard and can better cooperate with other mechanisms of the folding cardboard equipment to avoid the impact of height factors on the unloading and stacking of folding cardboard, thereby improving the overall working efficiency of the folding cardboard equipment.

[0025] The folding cardboard lifting platform of this embodiment also includes an adjustment component for driving the support platform 1 to move along the height direction. The adjustment component includes a support frame 2 for limiting the movement trajectory of the support platform 1. The support platform 1 moves along the extension direction of the support frame 2 to achieve lifting.

[0026] Specifically, a support frame 2 is set up to support the support platform 1. The support platform 1 is perpendicular to the support frame 2. The right angle structure between the two limits the repeated stacking of folded cardboard, ensuring the flatness of the cardboard stack. The support platform 1 always remains vertical during the movement along the support frame 2, preventing the cardboard stack from shaking and scattering during the lifting and lowering process.

[0027] Preferably, the support frame 2 is rotatable from the ground. When the support platform 1 receives the folded cardboard, the support frame 2 causes the support platform 1 to tilt at a certain angle to the ground, so that the support platform 1 matches the feeding direction of the folded cardboard in the folding cardboard equipment. This makes it easy for the folded cardboard to fall smoothly onto the support platform 1 and be stacked layer by layer to form a stack. At the same time, when the support platform 1 descends, the support frame 2 remains tilted. At this time, the cardboard stack fits tightly with the right-angle structure, which is beneficial for limiting the folded cardboard. When the support platform 1 drives the cardboard stack to the ground, the support frame 2 and the support platform 1 rotate synchronously, so that the cardboard stack is on a horizontal plane, which facilitates the connection between the cardboard stack and the transfer equipment on the ground to realize the unloading.

[0028] Specifically, the bottom of both ends of the support frame 2 are rotatably connected to the adapter on the ground through a rotating shaft. The bottom of the support frame 2 is hinged with a push-pull cylinder, which is rotatably connected to the ground. The extension and retraction of the push-pull cylinder drives the support frame 2 to rotate around the rotating shaft, thereby achieving the overall tilt or verticality, which is convenient for matching with folding cardboard equipment and for material unloading.

[0029] In the folding cardboard lifting platform of this embodiment, the adjustment component also includes a drive chain 3. The drive chain 3 is rotatably connected to the support frame 2 via a sprocket. The support platform 1 is fixedly connected to the drive chain 3 so as to follow the rotation of the drive chain 3 and reciprocate in the height direction to achieve lifting.

[0030] Specifically, the bottom of the support frame 2 is rotatably connected to a drive shaft, and drive sprockets are fixed at both ends of the drive shaft. Driven sprockets are set on both sides of the top of the support frame 2. Another set of chain and sprocket mechanism is set on the ground, and the drive shaft is driven to rotate through the mechanism, thereby driving the chain 3 to move on the support frame 2, and then driving the support platform 1 connected to the driving chain 3 to slide along the support frame 2 to achieve the lifting effect.

[0031] Preferably, an infrared sensor is provided around the periphery of the support platform 1 to detect the stacking height of the folded cardboard on the support platform 1. The infrared sensor is connected to the chain and sprocket mechanism on the ground. When the height of the cardboard blocks the infrared sensor, a signal is generated to control the chain and sprocket mechanism on the ground to drive the chain 3 to lower the support platform 1 to a set height. When the number of times the above process of lowering the set height is repeated reaches a preset value, it indicates that the height of the cardboard on the support platform 1 has reached the required height for stacking. Then the support platform 1 drives the folded cardboard to the ground for unloading.

[0032] In the folding cardboard lifting platform of this embodiment, first sliders are respectively provided on both sides of the support platform 1. The first sliders are slidably connected in the first slide rail 4 on the side of the support frame 2 near the support platform 1. When the support platform 1 moves along the support frame 2 with the drive chain 3, the first sliders slide along the first slide rail 4 to guide the support platform 1 and provide support and limit.

[0033] By setting the first slider to cooperate with the first slide rail 4, a stable support is provided for the support platform 1, restricting the rotation of the support platform 1 and the support frame 2, ensuring their vertical state. At the same time, the first slide rail 4 guides the first slider and the support platform 1 along the reciprocating motion of the support frame 2, so as to realize the smooth lifting and lowering of the support platform 1.

[0034] In the folding cardboard lifting platform of this embodiment, a feeding conveyor belt 5 is provided on the support platform 1. After the support platform 1 drives the folding cardboard to descend to the feeding point, the feeding conveyor belt 5 rotates to drive the folding cardboard away from the support platform 1 to achieve feeding.

[0035] Specifically, the unloading conveyor belts 5 are stacked, with their ends driven by a drive shaft and a driven shaft, respectively. The drive shaft is located below the driven shaft. A tensioning shaft is also provided between the two layers of unloading conveyor belts 5 to support and tension the unloading conveyor belts 5, ensuring that the upper surface of the unloading conveyor belts 5 is flat and perpendicular to the support frame 2, thereby receiving the folded cardboard. When the support platform 1 descends and rotates to a horizontal position with the support frame 2, the unloading conveyor belts 5 start to move the stack of folded cardboard on its surface along the horizontal plane until it detaches from the support platform 1. Preferably, a receiving conveyor belt of the same height as the rotated unloading conveyor belts 5 is provided on the ground to receive the stack of folded cardboard and complete the unloading process.

[0036] The folding cardboard lifting platform in this embodiment also includes a buffer platform 6, which is located above the support platform 1. The distance between the buffer platform 6 and the loading point is adjustable. The buffer platform 6 is close to the loading point and supports the folding cardboard so that the support platform 1 can drive the folding cardboard to descend and unload it.

[0037] By setting up a buffer platform 6, the folding cardboard continuously delivered by the folding cardboard equipment is temporarily received during the process of the support platform 1 lowering the cardboard to the ground, thus ensuring the continuity of the folding cardboard stacking.

[0038] Specifically, when the cardboard on the support platform 1 reaches the required height, the buffer platform 6 approaches the loading point and inserts between two adjacent folded cardboard units to separate the cardboard stack on the support platform 1 from the newly transferred folded cardboard. At the same time, the buffer platform 6 presses against the fold of the folded cardboard and cuts the fold with a cutting blade to separate the cardboard stack, so that the support platform 1 can drive the cardboard stack down for transportation and unloading.

[0039] In the folding cardboard lifting platform of this embodiment, the buffer platform 6 is slidably connected to the sliding frame 7. The buffer platform 6 slides back and forth along the sliding frame 7 to receive the folding cardboard near the loading point so that the support platform 1 can unload it, or to receive the folding cardboard away from the loading point so that the raised support platform 1 can receive it.

[0040] With the above setup, the buffer platform 6 temporarily receives the folded cardboard near the loading point. After the unloading is completed, the support platform 1 is raised, and the buffer platform 6 slides away from the loading point along the sliding frame 7. The folded cardboard on the buffer platform 6 falls onto the support platform 1 and continues to be stacked through the support platform 1.

[0041] Preferably, the surface of the buffer platform 6 is provided with multiple sets of spaced rollers to ensure stable support for the folded cardboard. At the same time, when the cardboard is away from the feeding point, it slides on the rollers, reducing the friction between the cardboard and the buffer platform 6, making it easier for the folded cardboard to fall onto the support platform 1.

[0042] Preferably, the sliding frame 7 can be tilted to match the tilt angle of the support frame 2 and the support platform 1, so that the buffer platform 6 and the support platform 1 are in a parallel state when they are close together, which facilitates the transfer of cardboard stacks and prevents the folded cardboard from scattering when it falls.

[0043] In the folding cardboard lifting platform of this embodiment, the sliding frame 7 is provided with a first rack 8, the first rack 8 is meshed with a first gear 9, there are two first gears 8, the two first gears 8 are respectively fixed at both ends of the first rotating shaft 10, the first rotating shaft 10 is rotatably connected to the connecting plate 11, and the two sides of the buffer platform 6 are slidably connected to the sliding frame 7 through the connecting plate 11.

[0044] Specifically, the first rack 8 is set on the lower side of the sliding frame 7, and the upper side of the sliding frame 7 is provided with a second slide rail. A second slider is slidably connected on the second slide rail. The second slider is fixed on the side of the connecting plate 11 away from the buffer platform 6. The second slider cooperates with the second slide rail to provide support and guidance for the connecting plate 11, so that the connecting plate 11 can slide along the sliding frame 7 to drive the buffer platform 6 closer to or away from the feeding point. At the same time, it is convenient to stably install the first gear 9 and the first rotating shaft 10.

[0045] Preferably, one end of the first rotating shaft 10 is connected to a drive motor, which drives the first rotating shaft 10 and the first gear 9 to rotate, thereby achieving sliding along the sliding frame 7 through cooperation with the first rack 8.

[0046] In the folding cardboard lifting platform of this embodiment, the buffer platform 6 is slidably connected to the connecting plate 11 to achieve lifting along the height direction, which facilitates the adjustment of the distance between the buffer platform 6 and the support platform 1, thereby allowing the folding cardboard on the buffer platform 6 to fall smoothly onto the support platform 1 to achieve buffering.

[0047] With the above configuration, the buffer platform 6 can gradually decrease in height as the folded cardboard is stacked, ensuring that the incoming direction of the folded cardboard is consistent, thus achieving smooth stacking. This avoids the increased height of the cardboard stack obstructing the folded cardboard and affecting normal stacking operations. At the same time, it allows sufficient time for the support platform 1 to descend, flip, unload, and rise, ensuring the stable operation of the support platform 1. In addition, the buffer platform 6 can descend to a position close enough to the support platform 1 to facilitate the transmission of the cardboard stack, reduce the height difference of the cardboard stack's descent, and improve the flatness of the cardboard stack stack.

[0048] In the folding cardboard lifting platform of this embodiment, slide plates 12 are provided on both sides of the buffer platform 6. The slide plates 12 are slidably connected to the guide rails on the connecting plate 11. A second rack 13 is provided on the side of the slide plate 12 away from the buffer platform 6. The second rack 13 is meshed with a second gear 14. The second gear 14 is rotatably connected to the connecting plate 11 through a second rotating shaft 15.

[0049] Specifically, the slide plate 12 is stably slidably connected to the connecting plate 11 through the guide rail structure. A second rack 13 is set on the slide plate 12. By driving the second rotating shaft 15 and the second gear 14, which are rotatably connected to the connecting plate 11, to rotate, the second rack 13 drives the slide plate 12 to slide along the guide rail under the meshing connection, thereby realizing the lifting function of the buffer platform 6.
