[0021] like Figures 1 to 8 As shown, a continuous folding cardboard folding and stacking device comprises: A stacking unit, the stacking unit supports the folded cardboard 1 that has been crimped and drives the folded cardboard 1 to flip over and stack. The stacking unit reciprocates between the folded cardboard 1 feeding position and the stacking position to continuously drive the folded cardboard 1 to move along the stacking direction for flipping and stacking. The transport unit is used to support the flipped and stacked folded cardboard 1. The height of the transport unit can be adjusted. The height of the transport unit is changed by adjusting the reciprocating motion of the transport unit between the stacking position and the unloading position, thereby driving the folded cardboard 1 carried on the transport unit to achieve lifting and unloading transportation.

[0022] In this embodiment, a stacking unit is provided to support and drive the folding cardboard 1. The folding cardboard 1 slides above the stacking unit and makes the folding point contact with the stacking unit. The folding cardboard units on both sides of the folding point will be folded down to achieve preliminary folding. As the stacking unit moves to the stacking position, the stacking unit is pulled out from between the folding cardboards 1. The folded cardboards 1 are stacked together under the action of gravity to complete the stacking and stacking. The cyclic action of the stacking unit drives the folding cardboards 1 to stack continuously, and the stacking efficiency is high. The stacking unit moves at a variable speed to avoid damage to the folding cardboards 1. The transport unit cooperates with the stacking unit to receive the folding cardboards 1 and carry the cardboards to achieve stacking. After the folding cardboards 1 are stacked to a certain height, the transport unit drives the folding cardboards 1 to descend in the height direction so that the folding cardboard stacks fall to the ground to achieve unloading. The transport unit reciprocates to improve the efficiency of transporting the folding cardboards 1.

[0023] In the continuous folded cardboard folding and stacking equipment of this embodiment, the stacking unit includes a driving component, and the driving component includes a plurality of support ropes 2 arranged at intervals. The support ropes 2 are arranged perpendicular to the stacking direction to facilitate contact with the fold of the folded cardboard 1, thereby folding the folded cardboard units on both sides of the fold for easy stacking.

[0024] Specifically, a support rope 2 is arranged to abut against the fold to provide stable support for the folding cardboard 1 and drive it to move along the stacking direction. At the same time, the support rope 2 has a small diameter and fits more closely with the fold. A small space is occupied between the folding cardboard units, so that when the folding cardboard 1 is driven to move, the folding cardboard units on both sides of the fold are folded and pressed tightly to achieve initial folding, which is more conducive to subsequent flipping and stacking.

[0025] At the same time, the support rope 2 abuts against the folding cardboard 1 to provide support, which causes little loss to the folding cardboard 1 and avoids causing new creases to the folding cardboard 1 in the process of driving the folding cardboard 1 to move, thereby improving the production quality and stacking quality of the folding cardboard 1.

[0026] The plurality of support ropes 2 provide continuous support and drive for the continuously loaded folding cardboard 1. The folding cardboard 1 between two adjacent support ropes 2 is V-shaped. Through the above arrangement, the folding cardboard 1 is wavy under the support of the plurality of support ropes 2, and the initial folding is achieved, which facilitates the subsequent pulling out of the support ropes 2 from the folding cardboard 1 to completely fold it tightly for stacking and stacking.

[0027] In the continuous folding cardboard folding and stacking equipment of this embodiment, a plurality of the support ropes 2 are respectively circulated and rotated along the periphery of the guide seat 3, two guide seats 3 are symmetrically arranged with respect to the stacking direction of the folded cardboard 1, a stacking channel is formed between the two guide seats 3, and the two ends of the support rope 2 are respectively rotatably connected to the guide seats 3 on both sides.

[0028] The guide seat 3 is provided to provide support and guidance for the support rope 2 and limit the stacking direction of the folded paperboard 1 so that the folded paperboard 1 preliminarily folded on the support rope 2 can be further folded to achieve stacking.

[0029] Preferably, a creasing machine is provided at the front end of the feeding place, and the creasing machine indents the cardboard to produce creases to facilitate the stacking of the folded cardboard. The creasing machine indents and drives the folded cardboard to move between the guide seats 3 to achieve feeding.

[0030] Specifically, a limit plate 4 is provided above the support rope 2, and the limit plate 4 is located on the side of the guide seat 3 close to the loading position. The limit plate 4 provides limit guiding support for the folding cardboard 1 loaded from the loading position to prevent the folding cardboard 1 from falling directly onto the support rope 2. When the support rope 2 moves below the limit plate 4, the movement speed decreases. When the previous support rope 2 is in contact with the folding cardboard 1 and drives the cardboard to move along the stacking direction until the folding cardboard 1 is in a V shape at the edge of the limit plate 4, the support rope 2 slides out from under the limit plate 4 and is in contact with another fold to drive the folding cardboard 1 to move, so that the folding cardboard 1 is in a wavy shape on the support rope 2, thereby ensuring that the folding cardboard 1 is stacked and stacked in sequence.

[0031] In the continuous folding cardboard folding and stacking device of this embodiment, the guide seat 3 is tilted at one end close to the stacking position to form a guide surface 5. When the support rope 2 moves along the guide surface 5, it drives the folding line and then drives the folding cardboard unit to rotate around the stacked cardboard to facilitate continuous stacking.

[0032] Specifically, the upper surface of the guide seat 3 is horizontal, and the guide surface 5 is inclined downward along the horizontal plane. When the support rope 2 moves from the horizontal plane to the guide surface 5, 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 support rope 2 close to the stacking position is lowered and limited by the transport unit or the stacked cardboard, and the folded cardboard unit rotates. As the height of the support rope 2 becomes lower and lower, the folded cardboard unit gradually fits the transport unit or the stacked cardboard. At this time, the support rope 2 is pulled out from between the folded cardboard units, and the next support rope 2 moves along the guide surface 5, so that the continuous stacking of the folded cardboard 1 is realized to achieve the stacking purpose.

[0033] In the continuous folded cardboard folding and stacking device of this embodiment, the stacking unit also includes a first driving assembly arranged on the guide seat 3, and the first driving assembly includes a chain group 6 rotatably connected to the guide seat 3. The two ends of the support rope 2 are respectively fixedly connected to the chain groups 6 on both sides to follow the chain group 6 to rotate around the guide seat 3 to drive the folded cardboard 1 to move along the stacking direction to achieve stacking.

[0034] Specifically, the chain group 6 includes a plurality of rotating chains, which are spaced apart on the sides of the guide seat 3. Both ends of the support rope 2 are fixedly connected to the corresponding rotating chains on both sides. The plurality of support ropes 2 are respectively connected to different rotating chains, so that the rotating chains drive the support ropes 2 to move and thus support the folding cardboard 1 to move and stack along the stacking direction.

[0035] Preferably, the rotation speed of the same rotating chain can be adjusted and set, and the speed of the support bar 2 decreases when it moves close to the guide surface 5, ensuring that the folding cardboard unit rotates smoothly around the transport unit or the stacked cardboard to complete continuous stacking, avoiding excessive speed causing the folding cardboard unit to get stuck and affect the stacking; when the folding cardboard unit completes stacking and the support rope 2 is pulled out from between the folding cardboards 1, the rotation speed of the rotating chain is accelerated to drive the support rope 2 to return to the loading place from under the guide seat 3 to continue to receive new folding cardboards 1, thereby ensuring the stacking quality of the folding cardboards 1 and improving the stacking efficiency.

[0036] In the continuous folding cardboard folding and stacking device of this embodiment, two supporting ropes are arranged relatively on the rotating chain, and the multiple rotating chains rotate around the guide seat respectively to drive the supporting ropes connected thereto to reciprocate to realize continuous feeding of the folded cardboard along the stacking direction.

[0037] Through the above arrangement, two support ropes 2 are arranged on each rotating chain. The shape of the guide seat 3 is arranged according to the distance between the loading place and the stacking place of the rotating chain, so that when the first support rope 2 on the rotating chain moves to the guide surface 5, the other support rope 2 moves to the bottom of the limit plate 4, and the speed is reduced simultaneously at two places, so that two support ropes 2 are installed on the same rotating chain while meeting the speed requirements of the folding cardboard 1 for the support rope 2, thereby improving the delivery efficiency, improving the stacking efficiency of the folding cardboard 1, reducing the number of rotating chains, simplifying the structure of the first drive component to a certain extent, and saving production costs.

[0038] In the continuous folded cardboard folding and stacking equipment of this embodiment, the transport unit includes a support platform 7 for supporting the folded cardboard 1, and an adjusting component for driving the support platform 7 to move along the height direction, and the adjusting component includes a support frame 8 for limiting the movement trajectory of the support platform 7, and the support platform 7 moves along the extension direction of the support frame 8 to achieve lifting.

[0039] Specifically, a support frame 8 is provided to provide support for the support platform 7, and the support platform 7 is perpendicular to the support frame 8. The repeatedly stacked folded cardboards 1 are limited by the right-angle structure between the two to ensure the flatness of the cardboard stack. The support platform 7 always maintains a vertical state during the movement along the support frame 8 to prevent the cardboard stack from shaking and spreading during the lifting process.

[0040] Preferably, the support frame 8 is rotatably arranged between the ground. When the support platform 7 receives the folded cardboard 1, the support frame 8 drives the support platform 7 to tilt at a certain angle with the ground, and cooperates with the guide surface 5 of the guide seat 3, so that the support platform 7 and the support rope 2 drive the cardboard along the guide seat 3. The incoming direction of the folded cardboard 1 matches, which is convenient for the support rope 2 to be pulled out and the folded cardboard 1 to fall steadily onto the support platform 7 and be stacked layer by layer to form a stack, thereby avoiding the cardboard stack from being skewed. At the same time, when the support platform 7 descends, the support frame 8 remains tilted. At this time, the cardboard stack is tightly fitted with the right-angle structure, which is conducive to limiting the folded cardboard 1; when the support platform 7 drives the cardboard stack to descend to the ground, the support frame 8 and the support platform 7 rotate synchronously, so that the cardboard stack is located on a horizontal plane, which is convenient for the cardboard stack to be connected with the transfer equipment on the ground to realize unloading.

[0041] Specifically, the bottom of both ends of the support frame 8 are rotatably connected to the adapter seat on the ground through a rotating shaft. The bottom of the support frame 8 is hinged with a push-pull cylinder, which is rotatably connected to the ground. The support frame 8 is driven to rotate around the rotating shaft through the extension and contraction of the push-pull cylinder to achieve overall inclination or verticality, which is convenient for matching with the stacking unit and facilitating material unloading.

[0042] In the continuous folding cardboard folding and stacking equipment of this embodiment, the adjusting component also includes a driving chain 9, which is rotatably connected to the support frame 8 through a sprocket, and the support platform 7 is fixedly connected to the driving chain 9 to follow the rotation of the driving chain 9 and reciprocate in the height direction to achieve lifting and lowering.

[0043] Specifically, the bottom of the support frame 8 is rotatably connected to a driving shaft, and driving sprockets are respectively fixed at both ends of the driving shaft. Driven sprockets are respectively arranged on both sides of the top of the support frame 8. Another set of chain and sprocket mechanisms is arranged on the ground, and the driving shaft is driven by the mechanism to drive the driving sprocket to rotate, thereby realizing the movement of the driving chain 9 on the support frame 8, and then driving the support platform 7 connected to the driving chain 9 to slide along the support frame 8, thereby realizing the lifting effect.

[0044] Preferably, infrared sensors are provided on the surrounding sides of the support platform 7 to detect the stacking height of the folded cardboard 1 on the support platform 7. The infrared sensor is connected to the signal of the chain sprocket mechanism on the ground. When the cardboard height blocks the infrared sensor, a signal is generated to control the chain sprocket mechanism on the ground to drive the chain 9 to drive the support platform 7 to descend to a set height. When the number of times the above-mentioned process of descending to a set height reaches a preset value, it indicates that the height of the cardboard on the support platform 7 has reached the required height for stacking, and then the support platform 7 drives the folded cardboard 1 to descend to the ground for unloading.

[0045] In the continuous folding cardboard folding and stacking equipment of this embodiment, first sliders are respectively provided on both sides of the support platform 7, and the first sliders are slidably connected in the first slide rails of the support frame 8 close to the support platform 7. When the support platform 7 moves along the support frame 8 along with the driving chain 9, the first slider slides along the first slide rail to guide the support platform 7 and provide support limit.

[0046] By setting the first slider in cooperation with the first slide rail, stable support is provided for the support platform 7, the rotation of the support platform 7 and the support frame 8 is restricted, and the vertical state of the two is ensured. At the same time, the first slide rail guides the reciprocating motion of the first slider and the support platform 7 along the support frame 8, so that the support platform 7 can be lifted and lowered smoothly.

[0047] In the continuous folded cardboard folding and stacking equipment of this embodiment, the transport unit also includes a buffer platform 10, which is located above the support platform 7. The distance between the buffer platform 10 and the stacking place can be adjusted. The buffer platform 10 is close to the stacking place and receives the folded cardboard 1 to facilitate the lowering of the support platform 7 to realize material unloading and transportation.

[0048] By providing the buffer platform 10, the folded cardboards 1 continuously delivered by the support rope 2 can be temporarily received when the support platform 7 descends to the ground with the cardboards at a certain height, thereby ensuring the continuity of the stacking of the folded cardboards 1.

[0049] Specifically, when the height of the cardboard on the supporting platform 7 reaches the required height, the buffer platform 10 is close to the stacking position and inserted between two adjacent folding cardboard units to separate the cardboard stack on the supporting platform 7 and the newly transferred folding cardboard 1. At the same time, the buffer platform 10 is against the crease of the folding cardboard 1, and the crease is cut by the slitting knife to achieve the division of the cardboard stack, so that the supporting platform 7 can drive the cardboard stack to descend for transportation and unloading.

[0050] In the continuous folding cardboard folding and stacking equipment of this embodiment, a slitting knife is provided on the side of the support platform 7 away from the buffer platform 10, and the slitting knife is slidably connected in the slitting seam. An avoidance groove is provided at the end of the buffer platform 10. The buffer platform 10 is close to the stacking position so that the avoidance groove is aligned with the slitting seam, which facilitates the slitting knife to move along the slitting seam to cut the folded cardboard 1.

[0051] Specifically, a positioning plate 24 is provided below the guide seat 3. The positioning plate 24 is tilted in the same direction as the supporting frame 8. A slitting slit is provided on the positioning plate 24, and a slitting knife is provided on the back of the positioning plate 24. When the supporting rope 2 drives the folding cardboard 1 to move onto the supporting platform 7, the positioning plate 24 limits and supports the inner side of the folding cardboard 1 to ensure that the folding cardboard 1 is evenly stacked on the supporting platform 7. When the height of the cardboard stack on the supporting platform 7 meets the packaging requirements, the buffer platform 10 approaches the positioning plate 24 and abuts against the positioning plate 24, and is inserted between two adjacent folding cardboard units to intercept the folding cardboard 1 brought by the supporting rope 2. At this time, the avoidance groove at the end of the buffer platform 10 is aligned with the slitting slit on the positioning plate 24. The slitting knife reciprocates in the slitting slit, and the avoidance groove provides an avoidance space for the slitting knife, thereby ensuring the cutting effect at the crease and avoiding damage to other positions of the cardboard.

[0052] In the continuous folded cardboard folding and stacking equipment of this embodiment, the buffer platform 10 is slidably connected to the sliding frame 11, and the buffer platform 10 slides back and forth along the sliding frame 11 to approach the positioning plate 24 to receive the folded cardboard 1 for easy unloading of the support platform 7, or to move away from the positioning plate 24 for easy reception of the folded cardboard by the raised support platform 7.

[0053] Through the above arrangement, the buffer platform 10 temporarily receives the folded cardboard 1 near the positioning plate 24, and the supporting platform 7 after unloading is raised, and the buffer platform 10 slides along the sliding frame 11 away from the stacking place, and the folded cardboard 1 on the buffer platform 10 falls onto the supporting platform 7 and continues to be supported by the supporting platform 7 to achieve continuous stacking.

[0054] Preferably, the surface of the buffer platform 10 is provided with multiple groups of rollers arranged at intervals to ensure stable support for the folded cardboard 1. At the same time, when the cardboard is far away from the stacking place, the cardboard slides on the rollers to reduce the friction between the cardboard and the buffer platform 10, making it easier for the folded cardboard 1 to fall onto the support platform 7.

[0055] Further preferably, the sliding frame 11 is tilted in accordance with the tilt angle of the supporting frame 8 and the supporting platform 7 so that the buffer platform 10 is parallel to the supporting platform 7 when they are close to each other, which facilitates the transfer of the cardboard stack and prevents the folded cardboard 1 from spreading when falling.

[0056] In the continuous folding cardboard folding and stacking equipment of this embodiment, a first rack 12 is provided on the sliding frame 11, and the first rack 12 is meshed and connected to the first gear 13. Two first gears 13 are provided, and the two first gears 13 are respectively fixed at both ends of a first rotating shaft 14, and the first rotating shaft 14 is rotatably connected to a connecting plate 15. Both sides of the buffer platform 10 are slidably connected to the sliding frame 11 through the connecting plates 15.

[0057] Specifically, the first rack 12 is arranged on the lower side of the sliding frame 11, and a second slide rail is arranged on the upper side of the sliding frame 11. A second slider is slidably connected to the second slide rail. The second slider is fixed to the side of the connecting plate 15 away from the buffer platform 10. The second slider cooperates with the second slide rail to provide support and guidance for the connecting plate 15, so that the connecting plate 15 can slide along the sliding frame 11 to drive the buffer platform 10 close to or away from the stacking place, and at the same time, it is convenient to stably install the first gear 13 and the first rotating shaft 14.

[0058] Preferably, one end of the first rotating shaft 14 is connected to a driving motor, which drives the first rotating shaft 14 and the first gear 13 to rotate, and then cooperates with the first rack 12 to achieve sliding of the connecting plate 15 and the buffer platform 10 along the sliding frame 11.

[0059] In the continuous folded cardboard folding and stacking equipment of this embodiment, the buffer platform 10 is slidably connected to the connecting plate 15 to achieve lifting and lowering in the height direction to facilitate adjustment of the distance between the buffer platform 10 and the supporting platform 7, so that the folded cardboard 1 on the buffer platform 10 can fall smoothly onto the supporting platform 7 to achieve buffering.

[0060] Through the above arrangement, the buffer platform 10 can gradually descend with the stacking of the folded cardboards 1, so as to cooperate with the guide seat 3 to ensure that the incoming direction of the folded cardboards 1 is consistent, so as to smoothly achieve stacking, avoid the blockage of the folded cardboards 1 caused by the increase in the height of the cardboard stack, which affects the normal stacking action to receive enough cardboards, and at the same time leave enough time for the support platform 7 to descend, turn over, unload and rise, so as to ensure the stable operation of the support platform 7. In addition, the buffer platform 10 can be lowered to a position close enough to the support platform 7 to facilitate the transmission of the cardboard stack, reduce the height difference of the cardboard stack, and improve the stacking flatness of the cardboard stack.

[0061] In the continuous folding cardboard folding and stacking equipment of this embodiment, slide plates 16 are provided on both sides of the buffer platform 10, and the slide plates 16 are slidably connected to the guide rails on the connecting plate 15. A second rack 17 is provided on the side of the slide plate 16 away from the buffer platform 10, and the second rack 17 is meshed and connected to the second gear 18, and the second gear 18 is rotatably connected to the connecting plate 15 through a second rotating shaft 19.

[0062] Specifically, the skateboard 16 is stably slidably connected to the connecting plate 15 through a guide rail structure, and a second rack 17 is provided on the skateboard 16. By driving the second rotating shaft 19 and the second gear 18 rotatably connected to the connecting plate 15, the second rack 18 drives the skateboard 16 to slide along the guide rail under the cooperation of the meshing connection, thereby realizing the lifting function of the buffer platform 10.

[0063] In the continuous folded cardboard folding and stacking equipment of this embodiment, the transport unit also includes an alignment component and a second driving component for driving the alignment component to move, the alignment component is located on the peripheral side of the stacked cardboard, the distance between the alignment component and the stacked cardboard is adjustable, the alignment component is close to the stacked cardboard and abuts against the side of the stacked cardboard to achieve neat arrangement of the folded cardboard in the stacked cardboard.

[0064] Specifically, the stacked cardboard refers to a cardboard stack formed by stacked folded cardboards 1. By setting an alignment component, the distance between the alignment component and the stacked cardboard is reduced until it abuts against the side of the stacked cardboard, so that the stacked folded cardboards 1 are aligned and arranged neatly, thereby ensuring that the side of the stacked cardboard is flat, avoiding misalignment between the folded cardboards 1, and affecting the subsequent packaging of the stacked cardboards, thereby improving the packaging quality of the folded cardboards 1, facilitating transportation, and avoiding deformation of the cardboards due to uneven arrangement of the folded cardboards 1 during transportation.

[0065] Specifically, the positioning plate 24 matches the alignment component to limit the other side of the stacked cardboard, and the alignment component is close to the stacked cardboard and cooperates with the positioning plate 24 to limit the side of the stacked cardboard from both sides, so that the upper and lower adjacent layers of folded cardboards 1 are arranged neatly, achieving the overall alignment and flatness of the stacked cardboard.

[0066] In the continuous folded cardboard folding and stacking device of this embodiment, the alignment component includes an alignment plate 20, which is close to the stacked cardboard and abuts against the side of the stacked cardboard to achieve neat arrangement of the folded cardboard 1 in the stacked cardboard.

[0067] Specifically, the alignment component also includes a guide plate fixed above the alignment plate 20 to guide the folded cardboard 1, so that the folded cardboard 1 can all enter between the alignment plate 20 and the positioning plate 24 for easy stacking. A support plate is also provided to provide support for the alignment plate 20 and the guide plate. The alignment plate 20 is provided on one side of the support plate close to the stacked cardboard to facilitate the abutment and alignment of the stacked cardboards. An angle is provided between the guide plate and the support plate to form an inclined surface for easy guidance of the folded cardboard 1.

[0068] In the continuous folding cardboard folding and stacking device of this embodiment, the second driving assembly includes a third driving assembly, the alignment assembly is located at the free end of the third driving assembly, and the third driving assembly is used to drive the alignment plate 20 to approach or move away from the stacked cardboard to achieve the distance adjustment between the alignment assembly and the stacked cardboard.

[0069] Specifically, the third driving assembly includes a first cylinder 21 and a first connecting seat. The first connecting seat is arranged on a side of the support plate away from the stacked cardboard. The telescopic end of the first cylinder 21 is fixedly connected to the first connecting seat. The first cylinder 21 is telescopically driven to drive the support plate and the alignment assembly to move closer to or away from the stacked cardboard for alignment or reset. The reset allows sufficient travel to drive the support plate to move, thereby achieving continuous operation and avoiding affecting the stacking of the folded cardboard 1.

[0070] Preferably, the alignment plate 20 is correspondingly tilted to match the tilted support platform 7 and the positioning plate 24, ensuring that the alignment surface of the alignment plate 20 abutting against the stacked cardboards is perpendicular to the support platform 7, thereby ensuring the alignment effect of the stacked cardboards.

[0071] In the continuous folding cardboard folding and stacking device of this embodiment, the driving assembly also includes a fourth driving assembly for driving the alignment assembly to rise and fall, the third driving assembly is located at the free end of the fourth driving assembly, and the fourth driving assembly moves to drive the third driving assembly and the alignment assembly away from the stacking cardboard to facilitate the stacking of the folded cardboard 1.

[0072] Specifically, the fourth drive assembly drives the third drive assembly and the alignment assembly to lower in the vertical direction to approach the stacked cardboard so as to facilitate the first cylinder 21 to extend and drive the alignment assembly to perform the alignment operation, or to rise in the vertical direction to move away from the stacked cardboard to avoid affecting the loading and stacking of the folded cardboard 1, and at the same time limit the movement stroke of the third drive assembly and the alignment assembly to ensure that the alignment assembly descends to a height matching the stacked cardboard to improve the alignment effect.

[0073] In the continuous folding cardboard folding and stacking device of this embodiment, the first cylinder 21 is fixedly mounted on the crossbeam 22, the free end of the fourth drive assembly is connected to the crossbeam 22, and the fourth drive assembly drives the third drive assembly and the alignment assembly to rise and fall smoothly through the crossbeam 22.

[0074] Specifically, a crossbeam 22 is provided to connect the third drive assembly and the fourth drive assembly to enhance the connection strength between the two, ensure that the third drive assembly stably retracts and drives the alignment assembly to move, and that the fourth drive assembly stably drives the alignment assembly to rise and fall, thereby improving the overall stability of the alignment device and further improving the alignment effect.

[0075] Specifically, the fourth driving assembly includes a second cylinder 23 arranged perpendicular to the first cylinder 21. The second cylinder 23 is arranged on the frame of the entire equipment. The free end of the second cylinder 23 is connected to the crossbeam 22 through a second connecting seat. The second cylinder 23 retracts and drives the crossbeam 22 to reciprocate in the vertical direction to achieve the raising or lowering of the alignment assembly.

[0076] The continuous folding cardboard folding and stacking equipment of this embodiment also includes a guide component for guiding the movement of the beam 22. The beam 22 is slidably connected to the guide component. Under the guiding action of the guide component, the fourth drive component drives the alignment component to rise and fall stably to approach or move away from the stacked cardboards to realize continuous operation of the alignment mechanism.

[0077] Specifically, the guide assembly includes a guide rail and a guide slider slidably connected to the guide rail. The guide slider is fixedly connected to the crossbeam 22. The guide rail is arranged parallel to the second cylinder 23 and is also fixedly connected to the frame of the entire equipment. When the second cylinder 23 is extended and retracted to drive the crossbeam 22 to rise and fall in the vertical direction, the guide slider slides along the extension direction of the guide rail to limit and guide the crossbeam 22, thereby ensuring the stable lifting and lowering of the crossbeam 22 and the alignment assembly.

[0078] On the other hand, the present application also proposes a continuous folding cardboard folding and stacking process, using any of the above-mentioned continuous folding cardboard folding and stacking equipment, the folding cardboard 1 after the indentation processing enters the stacking unit from the feeding position, and the stacking unit supports the folding cardboard 1 and drives the folding cardboard 1 to reduce the movement speed after approaching the stacking position, so that the folding cardboard 1 is smoothly turned over to achieve stacking; After the folded cardboards 1 are stacked to a set height above the transport unit, the transport unit descends in the height direction, driving the stacked folded cardboards 1 away from the stacking position so as to be close to the ground for easy unloading of the folded cardboards 1 stack. The transport unit that has completed unloading is reset to continue to receive the folded cardboards 1 driven by the stacking unit.

[0079] It can be expected that the folding and stacking process in this embodiment includes all the beneficial effects of the above-mentioned folding and stacking equipment, which will not be described in detail here.
