Before use, the feed side pressure cylinder 132 is in a retracted state to facilitate workers to place the cardboard pile. After the workers place the cardboard pile, the controller starts the feed side pressure cylinder 132 to extend so that the feed side pressure plate 133 limits the edge positions on both sides of the cardboard pile, thereby realizing rapid centering and positioning of the cardboard pile.

[0063] Preferably, the top of the feed side pressure plate 133 has an inclined surface to facilitate the initial placement or subsequent addition of the cardboard pile.

[0071] The fifth conveying mechanism 51 receives the processed cardboard and sends it to the stacking device 6 for alignment and stacking. Since the height of the cardboard gradually rises during the stacking process, the alignment position of the stacking device 6 rises accordingly. The present invention drives the discharge end of the fifth conveying mechanism 51 and the stacking device 6 to rise synchronously through the lifting mechanism 52. When ensuring that the stacking device 6 can complete the stacking work normally, it is ensured that there is a relatively unchanged height difference between the discharge end of the fifth conveying mechanism 51 and the stacking device 6, which effectively prevents the cardboard from falling and causing tilting and deviation.

[0073] Preferably, the fifth conveying mechanism 51 is a belt conveyor, and the belt roller at the discharge end thereof is rotatably connected to the lifting frame 522 , thereby ensuring that the height of the discharge end of the conveying mechanism 2 changes with the change of the lifting frame 522 .

[0074] Preferably, the fifth conveying mechanism 51 is a multi-belt belt conveyor, and a workpiece guide plate 511 is provided between the belts at the discharge end thereof, thereby ensuring that the cardboard can be smoothly delivered into the stacking device 6 .

[0075] Preferably, it also includes a sixth conveying mechanism 53 with an adjustable inclination angle, wherein the sixth conveying mechanism 53 is a belt conveyor and is drivingly connected to the belt roller at the feeding end of the fifth conveying mechanism 51; by adjusting the sixth conveying mechanism 53, the position height of the receiving cardboard of the present invention can be changed, and it can be matched with water-based ink printing machines with different discharge heights for use, and can be adjusted according to the site, and has the characteristics of a wide range of applications.

[0076] Preferably, an adjustable cylinder 531 is hinged on the frame 521 , and the adjustable cylinder 531 is hinged to the middle of the sixth conveying mechanism 53 , so the inclination angle of the sixth conveying mechanism 53 can be changed by extending and retracting the adjustable cylinder 531 .

[0077] Preferably, the lifting mechanism 52 also includes a second rack 526 vertically fixed on the frame 521 and a second gear 527 meshing with the second rack 526, and the second gear 527 is rotatably mounted on the lifting frame 522; the second gear 527 and the second rack 526 cooperate to perform lifting and limiting guiding, which can effectively improve the structural stability of the present invention.

[0078] Preferably, the second gear 527 is mounted on a belt roller shaft which is a discharging end of a belt conveyor with the fifth conveying mechanism 51 and is rotatably connected to the lifting frame 522 .

[0079] Preferably, a plurality of second pressure strips 512 for pressing materials are arranged equidistantly above the fifth conveying mechanism 51; the second pressure strips 512 can ensure smooth conveying of the cardboard and prevent the cardboard from tilting or sliding down during conveying.

[0080] Preferably, a gantry press frame 23 is fixed on the fifth conveying mechanism 51 , and the second press strip 512 is installed on the gantry press frame 23 .

[0081] Preferably, a telescopic frame 528 is installed on the frame 521, and the feeding end of the fifth conveying mechanism 51 is slidably connected to the telescopic frame 528; since the lifting frame 522 is lifted vertically, the telescopic frame 528 is set as a connecting unit between the frame 521 and the fifth conveying mechanism 51, which can prevent the belt of the fifth conveying mechanism 51 from being torn off during the rising process.

[0082] Preferably, the stacking device 6 includes a centering mechanism 61 for aligning both sides of the workpiece and a retaining frame 62 for limiting the output end position of the workpiece. The retaining frame 62 can be driven to rise and fall by the lifting mechanism 52. A stacking interval is left between the discharge end of the fifth conveying mechanism 51 and the retaining frame 62. The retaining frame 62 is provided with a centering mechanism 61 for aligning both sides of the workpiece in the stacking space.

[0083] When the stacking device 6 is in the starting state, the lifting mechanism 52 drives the baffle 62 to be located at the lowest position, and the fifth conveying mechanism 51 receives the finished cardboard sent from the front station and sends it to the stacking interval. The outer side of the finished cardboard is limited by the baffle 62 and falls into the stacking interval. Thereafter, the centering mechanism 61 starts to limit the position of both sides of the finished cardboard, and then the centering mechanism 61 is reset. Then, the lifting mechanism 52 drives the baffle 62 to rise to a height of the thickness of the cardboard, and then the above process is repeated to neatly stack multiple cardboards in the stacking interval.

[0084] It is worth mentioning that a forklift or a load-bearing plate can be placed under the stacking area to collect the finished cardboard piles, making it easier for workers to transfer them in batches.

[0085] Preferably, the baffle 62 includes a limit baffle 621 arranged on the side of the stacking interval away from the fifth conveying mechanism 51 and a connecting beam 622 with one end fixedly connected to the limit baffle 621, and the other end of the connecting beam 622 is adjustably mounted on the lifting frame 522 of the lifting mechanism 52; adjusting the position of the connecting beam 622 on the lifting frame 522 can change the width of the stacking interval, so that the distance between the limit baffle 621 and the fifth conveying mechanism 51 matches the width of the cardboard, thereby limiting the front and rear side positions of the cardboard entering the stacking interval, and realizing automatic front and rear alignment of unloading; in addition, the lifting mechanism 52 drives the lifting frame 522 to rise and fall, which can drive the limit baffle 621 to rise and fall vertically.

[0086] Preferably, the blocking frame 62 also includes a second chain 623, both ends of the second chain 623 are fixed on both ends of the connecting beam 622, the connecting beam 622 is slidably connected to the lifting frame 522, and the lifting frame 522 is rotatably connected to a second sprocket 624 meshing with the second chain 623, and the second sprocket 624 is connected to a first hand wheel; the worker can rotate the first hand wheel to transmit the second chain 623 matched with the second sprocket 624, that is, change the position of the second chain 623 matched with the second sprocket 624, and then drive the connecting beam 622 to move on the lifting frame 522, that is, change the horizontal position of the connecting beam 622.

[0087] It is worth mentioning that the lifting frame 522 is also rotatably connected to a tensioning wheel to ensure that the second chain 623 and the second sprocket 624 can fit closely.

[0088] Preferably, the centering mechanism 61 is slidably connected to the connecting beam 622, and the centering mechanism 61 is rotatably connected to a third sprocket 625, and the third sprocket 625 is meshed with the second chain 623 and is connected to a second hand wheel; a worker can change the position of the centering mechanism 61 on the connecting beam 622 by turning the second hand wheel, and adjust the centering mechanism 61 to the middle position of the stacking interval, so that the centering mechanism 61 can effectively complete the centering task.

[0089] It is worth mentioning that the centering mechanism 61 is slidably connected to the connecting beam 622 via a pulley.

[0090] Preferably, the centering mechanism 61 includes a gantry 611 installed on the blocking frame 62 and two pneumatic side pressure mechanisms 612 which are adjustably installed on the top beam of the gantry 611; by adjusting the positions of the two side pressure mechanisms 612 on the gantry 611, the alignment position of the centering mechanism 61 can be changed so that it can match the alignment of the cardboard length. Therefore, the present invention can be adjusted according to the length and width of the cardboard, and is suitable for palletizing cardboards of different sizes, and has the characteristics of a wide range of applications.

[0091] Preferably, the side pressure mechanism 612 includes a suspension arm 613 connected to the top beam of the gantry 611, a material unloading side pressure cylinder 614 installed on the suspension arm 613, and a material unloading side pressure plate 615 connected to the piston rod of the material unloading side pressure cylinder 614; after the cardboard falls into the stacking interval, the material unloading side pressure cylinder 614 extends to allow the material unloading side pressure plate 615 to push the edges of the left and right sides of the cardboard to complete the alignment.

[0092] Preferably, the top of the boom 613 is slidably connected to the top beam of the gantry 611 and is locked by means of screws threadedly connected to the boom 613 , i.e., the friction between the boom 613 and the gantry 611 is increased by tightening the screws against the top beam of the gantry 611 .

[0093] Preferably, the top of the unloading side pressure plate 615 has an inclined surface for guiding the cardboard. The design of the inclined surface makes it unnecessary to reset the centering mechanism 61 after it is started, which can simplify the original operation process. When the cardboard falls into the stacking area, it can be aligned through the limit baffle 621 and the unloading side pressure plate 615.

[0094] Preferably, it also includes a supporting mechanism 63 installed at the bottom of the blocking frame 62, the supporting mechanism 63 includes a supporting plate 631 hinged to the bottom of the blocking frame 62, a supporting cylinder 632 fixed on the blocking frame 62, and the piston rod of the supporting cylinder 632 is hinged to the supporting plate 631; because a space for a load-bearing plate or a forklift needs to be reserved below the stacking interval, the blocking frame 62 is still at a considerable distance from the ground when it is lowered to the lowest position, so the supporting mechanism 63 is set as a temporary supporting mechanism, which is also convenient for continuous stacking. During the production process, the forklift is replaced; the supporting cylinder 632 contracts to make the support plate 631 in a horizontal state. At this time, the cardboard is supported by the support plate 631 when it falls into the stacking interval. A load plate or a forklift is placed below the support plate 631 and a certain amount of cardboard pile is on the support plate 631 (this amount needs to ensure that the topmost cardboard is still within the action range of the side pressure mechanism after the cardboard falls into the load plate or the forklift). The supporting cylinder 632 is aired and extended to make the support plate 631 in a vertical state, and the stacked cardboard falls vertically.

[0095] Preferably, there are two supporting mechanisms 63 , and the two supporting plates 631 are respectively arranged at the bottom of the limiting baffle 621 and the lifting frame 522 .

[0096] The invention can automatically complete the processes of feeding, printing, cutting, waste separation and palletizing and stacking, has the characteristics of high production efficiency, high degree of automation and low labor cost, and can be suitable for processing cardboards of different sizes.

[0097] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the present invention.
