[0031] like Figures 1 to 8 As shown, a continuous folding cardboard stacking device includes:

[0032] The stacking unit supports the folded cardboard 1 that has been crimped and drives the folded cardboard 1 to flip and stack. The stacking unit reciprocates at the feeding point and the stacking point of the folded cardboard 1 to continuously drive the folded cardboard 1 to move along the stacking direction for flipping and stacking.

[0033] The transport unit is used to support the folded cardboard 1 after it has been flipped and stacked. The height of the transport unit is adjustable. By adjusting the reciprocating motion of the transport unit between the stacking point and the unloading point, the height of the transport unit is changed, thereby driving the folded cardboard 1 carried on the transport unit to achieve lifting and unloading transport.

[0034] In this embodiment, a stacking unit supports and drives the folded cardboard 1. The folded cardboard 1 slides above the stacking unit, causing the crease to abut against the stacking unit. The folded cardboard units on both sides of the crease fold downwards to achieve initial folding. As the stacking unit moves to the stacking position, it is pulled out from between the folded cardboard 1. The folded cardboard 1 stacks together under the action of gravity to complete the stacking. The stacking unit's cyclical movement drives the folded cardboard 1 to stack continuously, resulting in high stacking efficiency. The stacking unit's variable speed movement avoids damage to the folded cardboard 1. The transport unit works in conjunction with the stacking unit to receive the folded cardboard 1 and carry it to achieve stacking. After the folded cardboard 1 is stacked to a certain height, the transport unit drives the folded cardboard 1 to descend along the height direction so that the stack of folded cardboard can fall to the ground for unloading. The transport unit reciprocates to improve the efficiency of transporting the folded cardboard 1.

[0035] The folding and stacking device for continuously folding paperboard of the embodiment comprises a driving assembly, and the driving assembly comprises a plurality of support ropes 2 arranged at intervals, and the support ropes 2 are arranged perpendicularly to the stacking direction to facilitate abutting against the creases of the folded paperboard 1 and thereby folding the folded paperboard units on both sides of the creases to facilitate stacking.

[0036] Specifically, the support ropes 2 are arranged to abut against the creases to provide stable support for the folded paperboard 1 to move along the stacking direction, and the support ropes 2 have small diameters and are closely attached to the creases, occupy small space between the folded paperboard units, and facilitate folding the folded paperboard units on both sides of the creases to be closely attached to realize preliminary folding and facilitate subsequent folding and stacking.

[0037] Meanwhile, the support ropes 2 abut against the folded paperboard 1 to provide support, and the support ropes 2 have small loss to the folded paperboard 1, avoid causing new creases to the folded paperboard 1 in the process of driving the folded paperboard 1 to move, and thereby improve the production quality and stacking quality of the folded paperboard 1.

[0038] The plurality of support ropes 2 provide continuous support and driving for the continuously fed folded paperboard 1, the folded paperboard 1 between the adjacent two support ropes 2 is in a V shape, the folded paperboard 1 is arranged in a wave shape under the support of the plurality of support ropes 2 through the above arrangement, preliminary folding is realized, and the subsequent support ropes 2 are facilitated to be separated from the folded paperboard 1 to be completely attached and folded to realize stacking and storage.

[0039] In the folding and stacking device for continuously folding paperboard of the embodiment, a plurality of support ropes 2 are arranged to rotate along the periphery of the guide seat 3 respectively, the guide seat 3 is arranged symmetrically about the stacking direction of the folded paperboard 1, two guide seats 3 are arranged, a stacking channel is formed between the two guide seats 3, and both ends of the support rope 2 are rotatably connected to the guide seats 3 on both sides.

[0040] The guide seat 3 is arranged to provide support and guidance for the support rope 2 and simultaneously limit the stacking direction of the folded paperboard 1, so that the folded paperboard 1 preliminarily folded on the support rope 2 is further folded to realize stacking and storage.

[0041] Preferably, a creasing machine is arranged at the front end of the feeding position, the creasing machine is arranged to crease the paperboard to produce creases, facilitate folding and stacking of the paperboard, and the creasing machine is arranged to crease and drive the folded paperboard to move between the guide seats 3 to realize feeding.

[0042] Specifically, the upper part of the supporting rope 2 is provided with a limiting plate 4, which is located on one side of the guide seat 3 close to the feeding position. The limiting plate 4 guides and supports the folded paperboard 1 fed from the feeding position, so as to avoid the folded paperboard 1 from directly falling on the supporting rope 2. When the supporting rope 2 moves to the lower part of the limiting plate 4, the moving speed is reduced. When the last supporting rope 2 is in contact with the crease on the folded paperboard 1 and drives the paperboard to move in the stacking direction to the V-shaped edge of the limiting plate 4, the supporting rope 2 slides out from the lower part of the limiting plate 4 and is in contact with another crease to drive the folded paperboard 1 to move, so that the folded paperboard 1 is in a wave shape on the supporting rope 2, thereby ensuring that the folded paperboard 1 is stacked and placed in sequence.

[0043] In the continuous folded paperboard folding and stacking device, one end of the guide seat 3 close to the stacking position is inclined to form a guide surface 5. When the supporting rope 2 moves along the guide surface 5, the crease is driven to rotate the folded paperboard unit around the stacked paperboard, so as to realize continuous stacking.

[0044] 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 supporting rope 2 moves from the horizontal plane to the guide surface 5, the supporting rope 2 drives the folded paperboard 1 to move downward. At this time, the lower end of the folded paperboard unit on the side of the supporting rope 2 close to the stacking position is lowered and limited by the transportation unit or the already stacked paperboard. The folded paperboard unit rotates, and as the height of the supporting rope 2 becomes lower and lower, the folded paperboard unit gradually contacts the transportation unit or the already stacked paperboard. At this time, the supporting rope 2 is pulled out from between the folded paperboard units, and the next supporting rope 2 moves along the guide surface 5, realizing the continuous stacking of the folded paperboard 1 and achieving the stacking purpose.

[0045] In the continuous folded paperboard folding and stacking device, the stacking unit further comprises a first driving assembly arranged on the guide seat 3. The first driving assembly comprises a chain group 6 rotationally connected with the guide seat 3.

[0046] Specifically, the chain group 6 comprises a plurality of rotating chains. The plurality of rotating chains are arranged at intervals on the side edges of the guide seat 3. The two ends of the supporting rope 2 are fixedly connected with the corresponding rotating chains on both sides respectively. A plurality of supporting ropes 2 are connected with different rotating chains respectively, so that the rotating chains drive the supporting rope 2 to move and in turn drive the folded paperboard 1 to move in the stacking direction and stack.

[0047] Preferably, the rotating speed of the same rotating chain is adjustable, the speed of the support rope 2 is reduced when the support rope 2 moves close to the guide surface 5, so as to ensure that the folded paperboard unit rotates stably around the transport unit or the folded paperboard unit that has been stacked to complete the continuous stacking, and avoid that the folded paperboard unit is stuck due to too high speed, thereby affecting the stacking; after the support rope 2 is pulled out from between the folded paperboard 1, the rotating speed of the rotating chain is increased to drive the support rope 2 to return to the feeding position from below the guide seat 3 to continue to receive the new folded paperboard 1, so as to ensure the stacking quality of the folded paperboard 1 and improve the stacking and stacking efficiency.

[0048] In the continuous folded paperboard folding and stacking equipment, two support ropes are arranged on the rotating chain in opposition, and a plurality of rotating chains are arranged to rotate around the guide seat to drive the support ropes connected thereto to reciprocate to realize the continuous feeding of the folded paperboard in the stacking direction.

[0049] Through the above arrangement, two support ropes 2 are arranged on each rotating chain, the shape of the guide seat 3 is set according to the distance between the rotating chain and the feeding position and the stacking position, so that when the first support rope 2 on the rotating chain moves to the guide surface 5, the other support rope 2 moves below the limiting plate 4, and the speed is reduced at the two positions at the same time, so that the two support ropes 2 are installed on the same rotating chain, the speed requirement of the folded paperboard 1 on the support rope 2 is met, the delivery efficiency is improved, the folding and stacking efficiency of the folded paperboard 1 is improved, the number of rotating chains is reduced, the structure of the first driving assembly is simplified to a certain extent, and the production cost is saved.

[0056] Preferably, the support platform 7 is provided with an infrared sensor on the periphery to detect the stacking height of the folded paperboard 1 on the support platform 7, the infrared sensor is signal-connected to the chain and sprocket mechanism on the ground, when the paperboard height blocks the infrared sensor, a signal is generated to control the chain and sprocket mechanism on the ground to drive the driving chain 9 to drive the support platform 7 to descend by a set height, and when the number of times of repeating the above process of descending by a set height reaches a preset value, it indicates that the height of the paperboard on the support platform 7 has reached the required height of the stack, and then the support platform 7 drives the folded paperboard 1 to descend to the ground for unloading.
