Description

Technical Field

[0001] This utility model relates to the field of folding cardboard technology, and specifically to a folding cardboard stacking device. 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] In existing technology, folding cardboard equipment includes a conveying unit, a swaying unit, and a stacking unit. The swaying unit folds the cardboard by mimicking manual folding. To improve the efficiency of the folding equipment, the swaying speed is often increased. However, due to the limited toughness of the cardboard material itself, excessive creases will appear during high-speed swaying, resulting in a decrease in the folding quality of the cardboard. Utility Model Content

[0004] To address the shortcomings of existing technologies, a folding cardboard stacking device is proposed, which solves the problem that the cardboard material itself has limited toughness, resulting in excessive creases during high-speed oscillation, thus causing a decrease in the folding quality of the cardboard.

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

[0006] A folding cardboard stacking device includes a driving component, which supports the folding cardboard that has been crimped and drives the folding cardboard to flip and stack. The driving component reciprocates at the loading and unloading points of the folding cardboard to continuously drive the folding cardboard to move along the stacking direction and flip and stack it.

[0007] Furthermore, the driving component includes a support rope, which is arranged perpendicular to the stacking direction to facilitate contact with the creases of the folded cardboard, thereby allowing the folded cardboard units on both sides of the creases to be folded for easy stacking.

[0008] Furthermore, the support ropes are provided in several places, and the several support ropes are spaced apart to support the creases on the folded cardboard in turn and drive the folded cardboard to move along the stacking direction to achieve continuous stacking.

[0009] Furthermore, several of the support ropes rotate cyclically around the periphery of the guide seat. There are two guide seats symmetrically arranged about the stacking direction of the folded cardboard, and a stacking channel is formed between the two guide seats. The two ends of the support ropes are rotatably connected to the guide seats on both sides.

[0010] Furthermore, the guide seat is inclined at one end near the unloading point to form a guide surface. When the support rope moves along the guide surface, it drives the folds and thus drives the folded cardboard unit to rotate around the stacked cardboard so as to achieve continuous stacking.

[0011] Furthermore, the guide seat is provided with a drive assembly, which includes a chain assembly rotatably connected to the guide seat. The two ends of the support rope are respectively fixedly connected to the chain assemblies on both sides to follow the chain assemblies as they rotate around the guide seat, thereby driving the folded cardboard to move along the stacking direction to achieve stacking.

[0012] Furthermore, the support rope is connected to the chain assembly via a connecting component. The connecting component includes a connecting rod, and the two ends of the connecting rod are fixedly connected to the support rope and the chain assembly via a first connecting plate and a second connecting plate, respectively. The first connecting plate is slidably connected to the guide seat.

[0013] Furthermore, a guide plate is provided on the side of the guide seat near the stacking channel, and a guide rail is provided on the guide plate. The first connecting plate is slidably connected to the guide rail through a guide roller. When the chain group rotates along the guide seat, it drives the first connecting plate to slide along the guide plate, thereby realizing the delivery of folded cardboard by the support rope along the stacking direction.

[0014] Furthermore, the drive assembly also includes a sprocket assembly, which is rotatably connected to the guide seat. The chain assembly is meshed with the sprocket assembly, and the sprocket assembly is drive-connected to the drive shaft. The drive shaft drives the chain assembly and the support rope to rotate around the guide seat.

[0015] Furthermore, the chain assembly includes multiple rotating chains, each with two second connecting plates arranged opposite to each other. The multiple rotating chains rotate around the guide seat to drive the second connecting plates and support ropes connected to them to reciprocate, thereby realizing the continuous feeding of the folded cardboard along the stacking direction.

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

[0017] This application uses a drive component to support and drive the folded cardboard. The folded cardboard slides above the drive component and abuts against the drive component at the crease. The folded cardboard units on both sides of the crease will fold downward to achieve initial folding. As the drive component moves to the unloading point, it is pulled out from between the folded cardboards. The folded cardboards in the folded state are stacked together under the action of gravity to complete the stacking. The drive component cyclically drives the folded cardboard to stack continuously, resulting in high stacking efficiency. The drive component matches the crease, reducing the loss of cardboard.

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.

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.

[0025] like Figures 1 to 4 As shown, a folding cardboard stacking device includes a driving component. The driving component supports the folding cardboard 1 that has been crimped and drives the folding cardboard 1 to flip and stack. The driving component reciprocates at the feeding and unloading points of the folding cardboard 1 to continuously drive the folding cardboard 1 to move along the stacking direction and flip and stack.

[0026] The folded cardboard 1 is supported and driven by a drive component. The folded cardboard 1 slides above the drive component and the crease comes into contact with the drive component. The folded cardboard 1 units on both sides of the crease will fold downward to achieve initial folding. When the drive component moves to the unloading point, the drive component is pulled out from between the folded cardboard 1. The folded cardboard 1 is stacked together under the action of gravity to complete the stacking. The drive component circulates and drives the folded cardboard 1 to stack continuously, which has high stacking efficiency. The drive component moves at a variable speed to avoid damage to the folded cardboard 1.

[0027] In the folding cardboard stacking device of this embodiment, the driving component includes a support rope 2. The support rope 2 is arranged perpendicular to the stacking direction to facilitate contact with the crease of the folding cardboard 1, thereby making the folding cardboard 1 units on both sides of the crease fold for easy stacking.

[0028] Specifically, the support rope 2 is set to abut against the crease, providing stable support for the folded cardboard 1 and driving it to move along the stacking direction. The support rope 2 has a small diameter and fits more tightly with the crease. It occupies less space between the folded cardboard units, which makes it easier for the folded cardboard units on both sides of the crease to fold and stick together to achieve initial folding when the folded cardboard 1 is moved, which is more conducive to subsequent flipping and stacking.

[0029] Meanwhile, the support rope 2 abuts against the folded cardboard 1 to provide support, minimizing damage to the folded cardboard 1 and preventing new creases from being created on the folded cardboard 1 during its movement, thereby improving the production quality and stacking quality of the folded cardboard 1.

[0030] In the folding cardboard stacking device of this embodiment, several support ropes 2 are provided. The several support ropes 2 are spaced apart to support the creases on the folding cardboard 1 in turn and drive the folding cardboard 1 to move along the stacking direction to achieve continuous stacking.

[0031] Specifically, multiple support ropes 2 provide continuous support and drive for the continuously fed folded cardboard 1. The crease that fits with the support ropes 2 is the second crease 10, and the crease between the two second creases 10 is the first crease 11. Between two adjacent support ropes 2, two folded cardboard units form a V-shape under the action of gravity and the first crease 11. These two folded cardboard units overlap with the second crease 10 between the two folded cardboard units on the adjacent two support ropes 2. Through the above arrangement, the folded cardboard 1 forms a wave shape under the support of multiple support ropes 2, realizing the initial folding, which facilitates the subsequent removal of the support ropes 2 from the folded cardboard 1 for complete folding and stacking.

[0032] In the folding cardboard stacking device of this embodiment, several support ropes 2 rotate cyclically around the periphery of the guide seat 3. There are two guide seats 3 symmetrically arranged about the stacking direction of the folding cardboard 1, and a stacking channel is formed between the two guide seats 3. The two ends of the support ropes 2 are rotatably connected to the guide seats 3 on both sides.

[0033] The guide seat 3 provides support and guidance for the support rope 2, while limiting the stacking direction of the folded cardboard 1, so that the folded cardboard 1 initially folded on the support rope 2 can be further folded to achieve stacking.

[0034] Preferably, a limiting plate 12 is provided above the support rope 2. The limiting plate 12 is located on the side of the guide seat 3 near the feeding point. The limiting plate 12 provides limiting and guiding support for the folded cardboard 1 fed from the feeding point, preventing the folded cardboard 1 from falling directly onto the support rope 2. When the support rope 2 moves below the limiting plate 12, the movement speed decreases. When the previous support rope 2 is in contact with the second crease 10 on the folded cardboard 1, it drives the cardboard to move along the stacking direction until the folded cardboard 1 forms a V shape under the action of the first crease 11. Then, the support rope 2 slides out from below the limiting plate 12 and is in contact with another second crease 10, driving the folded cardboard 1 to move, so that the folded cardboard 1 is wavy on the support rope 2, thereby ensuring that the folded cardboard 1 is stacked in sequence.

[0035] In the folding cardboard stacking device of this embodiment, the guide seat 3 is inclined at one end near the unloading point to form a guide surface 4. When the support rope 2 moves along the guide surface 4, it drives the folding cardboard 1 unit to rotate around the stacked cardboard in order to achieve continuous stacking.

[0036] Specifically, the upper surface of the guide seat 3 is horizontal, and the guide surface 4 is inclined downward along the horizontal surface. When the support rope 2 moves from the horizontal surface to the guide surface 4, the support rope 2 drives the folded cardboard 1 to move downward. At this time, the lower end of the folded cardboard unit on the side of the support rope 2 near the unloading point descends and is limited by the stacking platform or the already stacked cardboard. The folded cardboard unit rotates. As the height of the support rope 2 decreases, the folded cardboard unit gradually fits the stacking platform or the already stacked cardboard. At this time, the support rope 2 is pulled out from between the folded cardboard units, and at the same time, the next support rope 2 moves along the guide surface 4 to realize the continuous stacking of the folded cardboard 1 to achieve the stacking purpose.

[0037] In the folding cardboard stacking device of this embodiment, a driving component is provided on the guide seat 3. The driving component includes a chain group 5 rotatably connected to the guide seat 3. The two ends of the support rope 2 are respectively fixedly connected to the chain group 5 on both sides to follow the chain group 5 to rotate around the guide seat 3 so as to drive the folding cardboard 1 to move along the stacking direction to achieve stacking.

[0038] Specifically, the chain assembly 5 includes multiple rotating chains, which are spaced apart on the side of the guide seat 3. The two ends of the support rope 2 are fixedly connected to the corresponding rotating chains on both sides. The multiple support ropes 2 are connected to different rotating chains so that the rotating chains can drive the support ropes 2 to move and support the folded cardboard 1 to move and stack along the stacking direction.

[0039] Preferably, the rotation speed of the same rotating chain is adjustable. When the support bar 2 moves close to the guide surface 4, the speed decreases to ensure that the folded cardboard unit rotates smoothly around the stacking platform or the already stacked cardboard to complete continuous stacking, avoiding the folded cardboard unit from getting stuck due to excessive speed and affecting stacking. When the folded cardboard unit is stacked, the support rope 2 is pulled out from between the folded cardboard 1, and the rotation speed of the rotating chain increases to drive the support rope 2 back from below the guide seat 3 to the feeding point to continue to receive new folded cardboard 1, ensuring the stacking quality of the folded cardboard 1 while improving stacking efficiency.

[0040] In the folding cardboard stacking device of this embodiment, the support rope 2 is connected to the chain group 5 through a connecting component. The connecting component includes a connecting rod 6. The two ends of the connecting rod 6 are fixedly connected to the support rope 2 and the chain group 5 respectively through a first connecting plate 7 and a second connecting plate 8. The first connecting plate 7 is slidably connected to the guide seat 3.

[0041] Specifically, the lengths of the connecting rods 6 at both ends of each support rope 2 are different, matching the distance between the rotating chain that drives the support rope 2 and the edge of the guide seat 3. The rotating chain rotates around the guide seat 3, causing the second connecting plate 8, connecting rods 6, and first connecting plate 7 to slide along the guide seat 3, thereby realizing the rotational connection between the support rope 2 and the guide seat 3.

[0042] In the folding cardboard stacking device of this embodiment, a guide plate 9 is provided on the side of the guide seat 3 near the stacking channel, and a guide rail is provided on the guide plate 9. The first connecting plate 7 is slidably connected to the guide rail through a guide roller. When the chain group 5 rotates along the guide seat 3, it drives the first connecting plate 7 to slide along the guide plate 9, thereby realizing that the support rope 2 delivers the folding cardboard 1 along the stacking direction.

[0043] Specifically, the guide rail includes a first guide rail set at the bottom of the guide plate 9 and a second guide rail set at the top of the guide plate 9. The first connecting plate 7 is slidably connected to the first guide rail via a first guide roller. A second guide roller is slidably connected on the second guide rail. The second guide roller is rotatably connected below the slide plate 13. The slide plate 13 is fixedly connected to the first connecting plate 7. The two sets of guide rail and guide roller mechanisms achieve stable guidance of the support rope 2, ensuring that the support rope 2 rotates smoothly along the guide seat 3.

[0044] In the folding cardboard stacking device of this embodiment, the driving component further includes a sprocket assembly, which is rotatably connected to the guide seat 3. The chain assembly 5 is meshed with the sprocket assembly, and the sprocket assembly is driven to the drive shaft. The drive shaft drives the chain assembly 5 and the support rope 2 to rotate around the guide seat 3.

[0045] Specifically, the sprocket assembly includes multiple sets of corresponding rotating drive sprockets 14 and rotating driven sprockets 15. The rotating drive sprockets 14 are located at the feeding end, and the rotating driven sprockets 15 are located at the unloading end. Multiple drive shafts are provided and are respectively connected to the rotating drive sprockets 14 for transmission. Through the above arrangement, the drive shaft located at the unloading end is avoided from affecting the stacking of folded cardboard 1, and the support rope 2 is easy to pull out and reset.

[0046] Preferably, each rotating drive sprocket 14 is connected to the drive shaft via a drive sprocket chain structure. The driven drive sprocket is fixed to the rotating drive sprocket 14 on a sleeve. Multiple sleeves are fitted onto the rotating shaft and rotatably connected to the rotating shaft. The driven drive sprocket meshes with the driven drive sprocket via a drive chain. Multiple driven drive sprockets are fixed to the ends of the drive shaft. The drive shaft is connected to a drive motor. The drive motor controls the rotation speed of the drive shaft, thereby controlling the movement speed of the support rope 2 around the guide seat 3, improving the stacking efficiency of the folded cardboard 1.

[0047] In the folding cardboard stacking device of this embodiment, two second connecting plates 8 are arranged opposite each other on the rotating chain. Multiple rotating chains rotate around the guide seat 3 to drive the second connecting plates 8 and the support rope 2 connected thereto to reciprocate so as to realize the continuous feeding of the folding cardboard 1 along the stacking direction.

[0048] With the above setup, each rotating chain is equipped with two support ropes 2. The two support ropes 2 improve delivery efficiency and reduce the number of rotating chains, which simplifies the structure of the drive assembly to a certain extent and saves production costs.
