Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of continuous paperboard stacking, more particularly, it relates to a continuous paperboard stacking machine and a stacking method thereof. BACKGROUND

[0002] Corrugated paperboard is a composite material composed of at least one corrugated core paper and one or more flat box paper. Due to its unique structural design, it has the characteristics of light weight and high strength, and has become the mainstream material in the packaging field.

[0003] In the packaging process of corrugated paperboard, the corrugated paperboard needs to be continuously stacked, and then packaged. In the continuous paperboard stacking process, multiple paperboards are continuously stacked according to certain rules and sequences. After the paperboard stacking is completed, it is convenient for subsequent packaging and processing of the paperboard.

[0004] At present, after the corrugated paperboard is cut, the paperboard is conveyed to the position of the stacking machine, and the paperboard is stacked at the position of the stacking machine. After the stacking is completed, the paperboard is conveyed to the next station for packaging and processing, thereby completing the processing of the paperboard and realizing the packaging of the paperboard.

The position of the pressing piece is adjusted by the adjusting assembly 2, so that it conforms to the size of the paperboard. One side of the adjusting assembly 2 is provided with a conveying assembly 5.

[0042] Among them, the conveying frame 1 is the main placing frame in the whole paperboard stacking, which provides a placing space for the paperboard stacking.

[0043] The paperboard is input by adjusting the position of the adjusting assembly 2, the paperboard is assisted in conveying by the conveying mechanism when the paperboard is input, and the movement of the paperboard at the adjusting assembly 2 is powered, then the conveying is followed to realize the stacking of the paperboard, and the paperboard is conveyed to the next station by the conveying assembly 5 for packaging treatment after the stacking of the paperboard is completed.

[0044] The conveying mechanism comprises conveying rollers and a driving mechanism, and the movement and conveying of the paperboard are assisted by the driving mechanism controlling the conveying rollers.

[0045] The conveying assembly 5 is composed of an electric conveying belt, and the paperboard can be conveyed to the next processing station through the conveying assembly 5.

[0046] The specific structure of the adjusting assembly 2 is as follows: Referring to Figures 3-8 , the adjusting assembly 2 comprises a first guide structure 21, an opposite side of the first guide structure 21 is provided with a second guide structure 22, and a first adjusting mechanism 23 and a second adjusting mechanism 24 are sequentially arranged at the middle positions of the first guide structure 21 and the second guide structure 22.

[0047] Among them, the first guide structure 21 and the second guide structure 22 are arranged on the inner side wall of the conveying frame 1, the second guide structure 22 comprises a guide frame, the bottom of the guide frame is provided with a rack, four sets of gears meshing with the rack, the four sets of gears are respectively a first gear, a second gear, a third gear and a fourth gear, the first guide structure 21 is arranged in the same way as the second guide structure 22, the bottom of the first guide structure 21 is provided with a rack, and four sets of gears are arranged in meshing with the rack, the four sets of gears are respectively a fifth gear, a sixth gear, a seventh gear and an eighth gear.

[0048] The first adjusting mechanism 23 is matched with two sets of gears of the first guide structure 21 and the second guide structure 22 respectively, and the position of the first adjusting mechanism 23 is further moved along the rack through the gears, the second adjusting mechanism 24 is arranged in the same way as the first adjusting mechanism 23 in cooperation with the first guide structure 21 and the second guide structure 22, therefore, the adjustment of the positions of the first adjusting mechanism 23 and the second adjusting mechanism 24 can be realized through the meshing of the gears and the rack, the positions of the second adjusting mechanism 24 will be adjusted, for example, when the size of the paperboard changes, the first adjusting mechanism 23 can be adjusted to cooperate with the paperboard, the first adjusting mechanism 23 acts on the paperboard to reduce the deviation of the position of the paperboard, in order to make the second adjusting mechanism 24 further act on the paperboard, the second adjusting mechanism 24 can adjust the position to follow the first adjusting mechanism 23, so that the second adjusting mechanism 24 can act on the paperboard to further reduce the deviation of the paperboard.

[0049] The meshing of the gears and the rack can realize the structure of movement adjustment, which provides conditions for the adjustment of the subsequent tabletting position.

[0050] Based on the above adjustment condition has set up, still need to set up the structure of first adjusting mechanism 23, second adjusting mechanism 24, realize the adjustment of the position of the pressing piece.

[0051] The specific structure of the first adjusting mechanism 23 is as follows: Referring to Figures 3-8 , the first adjusting mechanism 23 includes a first adjusting rod 234, and a plurality of first pressing pieces 235 are arranged on the first adjusting rod 234, the first pressing pieces 235 are fixedly connected with the first adjusting rod 234, when the position of the first adjusting rod 234 changes, the position of the first pressing pieces 235 will change accordingly, so that the first pressing pieces 235 are adapted to the size of the paperboard.

[0052] Referring to Figures 3-8 , the first adjusting mechanism 23 further includes a first fixed plate 231, one side of the first fixed plate 231 is provided with a first conveying motor 232, the output end of the first conveying motor 232 is connected with a first transmission structure 233 penetrating through the first fixed plate 231, and one side of the first transmission structure 233 is provided with a first connecting rod 236.

[0053] The first transmission structure 233 includes a driving wheel, a driven wheel and a transmission belt, the driving wheel and the driven wheel are both gears, and the transmission belt is a meshing driving transmission belt, that is, the transmission belt is provided with teeth inside, the transmission belt can be meshed with the driving wheel and the driven wheel respectively, the output end of the first conveying motor 232 is meshed with the driving wheel, the first conveying motor 232 can drive the driving wheel to rotate, and the driving wheel can further drive the driven wheel to rotate through the transmission belt, the first gear is arranged on one side of the driven wheel of the first conveying motor 232, the fifth gear is arranged on the side opposite to the first gear, the second gear is arranged on one side of the first gear, and the sixth gear is arranged on the side opposite to the second gear.

[0054] The first gear and the fifth gear are provided with the first connecting rod 236 at the middle position, one end of the first connecting rod 236 penetrates through the first fixed plate 231, the first gear and the driven wheel of the first conveying motor 232 are connected in sequence, the other end of the first connecting rod 236 is provided with an adapter plate, the first connecting rod 236 penetrates through the first adapter plate and is connected with the fifth gear, and the first fixed plate 231 and the first adapter plate are connected through the first connecting rod 236.

[0055] In addition, the first gear, the second gear, the fifth gear and the sixth gear are respectively provided with a group of guide wheels above, and the four groups of guide wheels are respectively connected with the first adapter plate and the first fixed plate 231.

[0056] A first transfer mechanism is formed by assembling a first conveyor motor 232, a first fixed plate 231, a first adapter plate, a second guide structure 22, a first guide structure 21, a first connecting rod 236, and several guide wheels. When the first conveyor motor 232 is started, it can drive the first connecting rod 236 to rotate through the first transmission structure 233. Since the two ends of the first connecting rod 236 are respectively meshed with the second guide structure 22 and the first guide structure 21 through gears, the first fixed plate 231, the first adapter plate, and the first connecting rod 236 can all move along the first guide structure 21 and the second guide structure 22 under the drive of the first conveyor motor 232, thereby realizing the movement of positions.

[0057] See Figure 8 An adjusting motor 237 is provided on one side of the first conveying motor 232. The output end of the adjusting motor 237 is connected to a second transmission structure 238. A first adjusting rod 234 is provided on one side of the second transmission structure 238. Several first pressing plates 235 are provided on the first adjusting rod 234.

[0058] The adjusting motor 237 is connected to the first fixed plate 231 through a support frame. A second transmission structure 238 is provided inside the support frame. The second transmission structure 238 has the same structure as the first transmission structure 233, that is, the second transmission structure 238 and the first transmission structure 233 are transmitted through the same structure. The output end of the adjusting motor 237 passes through the support frame and is connected to the driving wheel of the second transmission structure 238. The driven wheel of the second transmission structure 238 is connected to the first adjusting rod 234. The end of the first adjusting rod 234 away from the second transmission structure 238 is connected to the first adapter plate. The first adjusting rod 234 is connected to several first pressure plates 235. Therefore, when the first fixed plate 231 is displaced in the direction, the first pressure plates 235 are displaced in the direction along with the first adjusting rod 234, the second transmission structure 238, and the adjusting motor 237.

[0059] By setting the above structure, several first pressing sheets 235 can achieve horizontal displacement, which facilitates corresponding adjustments according to different sizes of cardboard.

[0060] In addition, since the cardboard is input from the first adjustment mechanism 23, during the input process, due to the impact of the cardboard from the front and rear and the difference in cardboard thickness, the cardboard will impact the first pressure plate 235. The cardboard will deform under the impact, affecting the use of subsequent cardboard. Therefore, by setting the adjustment motor 237 and the second transmission structure 238 in conjunction with the first adjustment rod 234, the position of the first pressure plate 235 can be changed. That is, by adjusting the motor 237, the height of the first pressure plate 235 can be adjusted, so that the cardboard can be input quickly.

[0061] Specifically, when the adjusting motor 237 is started, since the adjusting motor 237 is connected to the second transmission structure 238, the driven wheel of the second transmission structure 238 rotates under the drive of the adjusting motor 237. Under the drive of the driven wheel of the second transmission structure 238, the first adjusting rod 234 deflects along with the driven wheel, and the position of the first pressing plate 235 connected to the first adjusting rod 234 changes, reducing the possibility of deformation of the cardboard.

[0062] In order to further match the dimensions of the sheet and the cardboard, the second adjustment mechanism 24 needs to be further designed. The specific structure of the second adjustment mechanism 24 is as follows: See Figures 3-8 The second adjustment mechanism 24 includes a second fixed plate 241. A second conveying motor 243 is provided on one side of the second fixed plate 241. The output end of the second conveying motor 243 is connected to a third transmission structure 242. A second adjustment rod 247 is provided on one side of the third transmission structure 242. A plurality of second pressure plates 2402 are provided on the second adjustment rod 247.

[0063] The structure of the third transmission structure 242 is the same as that of the first transmission structure 233. That is, the third transmission structure 242 and the first transmission structure 233 are transmitted through the same structure. When the second conveyor motor 243 is started, the second conveyor motor 243 can drive the drive wheel of the third transmission structure 242 to rotate. The drive wheel of the third transmission structure 242 can then drive the driven wheel of the third transmission structure 242 to rotate through the conveyor belt. The third gear is set on one side of the driven wheel of the third transmission structure 242, the seventh gear is set on the side opposite to the third gear, the fourth gear is set on one side of the third gear, and the eighth gear is set on the side opposite to the fourth gear.

[0064] A second connecting rod 246 is provided at the middle position between the third gear and the seventh gear. One end of the second connecting rod 246 passes through the second fixed plate 241, the third gear and the driven wheel of the third transmission structure 242 in sequence and is connected. The other end of the second connecting rod 246 is provided with two adapter plates. The second connecting rod 246 passes through the second adapter plates and is connected to the seventh gear. The second fixed plate 241 and the second adapter plate are connected by the second connecting rod 246.

[0065] In addition, a set of guide wheels is provided above the third gear, the fourth gear, the seventh gear, and the eighth gear, and the four sets of guide wheels are respectively connected to the second adapter plate and the second fixing plate 241.

[0066] A second transfer mechanism is formed by assembling a second conveying motor 243, a second fixed plate 241, a second adapter plate, a second guide structure 22, a first guide structure 21, a second connecting rod 246, and several guide wheels. When the second conveying motor 243 is started, it drives the second connecting rod 246 to rotate via the third transmission structure 242. Since the two ends of the second connecting rod 246 are respectively meshed with the second guide structure 22 and the first guide structure 21 through gears, the second fixed plate 241, the second adapter plate, and the second connecting rod 246 move along the first guide structure 21 and the second guide structure 22 under the drive of the second conveying motor 243, thereby realizing the movement of positions.

[0067] Since the second adjusting rod 247 is located on one side of the second fixed plate 241, and both ends of the second adjusting rod 247 are connected to the second adapter plate and the second fixed plate 241 respectively, when the positions of the second fixed plate 241 and the second adapter plate move, the second adjusting rod 247 moves along with the second fixed plate 241 and the second adapter plate, and thus a number of second pressure plates 2402 located on the second adjusting rod 247 move along with the second adjusting rod 247, thereby realizing the movement of the position of the second pressure plates 2402.

[0068] By adjusting the positions of the first pressure plate 235 and the second pressure plate 2402, the spacing can be adjusted according to the length of the corrugated paper, forming a channel-like limiting structure. When the corrugated paper is slightly offset, it will contact the first pressure plate 235 and the second pressure plate 2402. The blocking effect of the first pressure plate 235 and the second pressure plate 2402 can correct the position of the corrugated paper and bring it back to the predetermined stacking track, reducing the possibility of cardboard skewing or misalignment.

[0069] By setting the second pressing plate 2402 and the first pressing plate 235 to be adjusted horizontally and backward, the second pressing plate 2402 and the first pressing plate 235 can be adapted to cardboard of different lengths, which brings convenience to cardboard stacking. In addition to considering the length of the cardboard, the width of the cardboard also needs to be considered. To take into account the width of the cardboard, multiple sets of second pressing plates 2402 and first pressing plates 235 are set to adapt to cardboard of different widths. Within the width range pressed by the second pressing plate 2402 and the first pressing plate 235, the cardboard that it adapts to can be stacked.

[0070] In addition, at the junction of the second pressing sheet 2402 and the first pressing sheet 235, the second pressing sheet 2402 and the first pressing sheet 235 are staggered, which reduces the possibility of misalignment of the paperboard.

[0071] Both the second pressing plate 2402 and the first pressing plate 235 are spring steel sheets. Spring steel sheets have high rigidity, providing stable flattening force and effectively constraining the stacked cardboard; at the same time, they have good elasticity, allowing them to adapt to changes in the thickness of the stacked cardboard, maintaining moderate and continuous pressure, and preventing excessive compression that could cause cardboard deformation. In actual cardboard stacking, in addition to considering the width and length of the cardboard, the thickness of the cardboard also needs to be taken into account. For cardboard with different thicknesses, adaptive adjustments are required.

[0072] See Figure 4 and Figure 5 A second connecting rod 246 is provided on one side of the second adjusting rod 247. Two sets of adjusting cylinders 248 are symmetrically arranged on the side of the second connecting rod 246 away from the second adjusting rod 247. A set of connecting blocks 249 is provided at the output end of each set of adjusting cylinders 248. The connecting blocks 249 and the output end of the adjusting cylinders 248 are hinged. An auxiliary rod 2401 and a mounting rod 244 are provided on both sides of the output end of each set of adjusting cylinders 248. The auxiliary rod 2401 is rotatably connected to the connecting block 249, and the mounting rod 244 is fixedly connected to the connecting block 249. Several pressure rollers 245 are sleeved on the outer side of the mounting rod 244.

[0073] The auxiliary rod 2401 is rotatably connected to the second adapter plate, and the mounting rod 244 is fixedly connected to the second adapter plate. The auxiliary rod 2401 serves as an auxiliary connector, providing the possibility of adjusting the position of the mounting rod 244. When the two sets of adjusting cylinders 248 are activated, they extend and drive the two sets of connecting blocks 249 to rotate along the auxiliary rod 2401, i.e., the two sets of connecting blocks 249 swing. At this time, the mounting rod 244, which is fixedly connected to the two sets of connecting blocks 249, swings with the two sets of connecting blocks 249, thereby adjusting the position of several pressure rollers 245. If the two sets of adjusting cylinders 248 retract in the opposite direction, the position of the pressure rollers 245 moves in the opposite direction. When the cardboard is thick, the gap between the pressure rollers 245 and the cardboard can be increased by adjusting the two sets of adjusting cylinders 248. When the cardboard is thin, the gap between the pressure rollers 245 and the cardboard can be decreased by adjusting the two sets of adjusting cylinders 248.

[0074] By using appropriate pressure, the possibility of cardboard misalignment can be reduced. In addition, for thin or soft cardboard, the downward pressure provided by the pressure roller 245 can suppress its drift caused by gravity or airflow, maintain the conveying posture, and reduce the possibility of misalignment of stacked layers.

[0075] In Example 2, the above structure can reduce the possibility of misalignment of the cardboard during stacking. However, when the cardboard is fed into the adjustment component 2, the cardboard will drift during the conveying process, that is, the cardboard will deviate during the conveying process. In order to reduce the possibility of the cardboard deviating during the input process, an adsorption component 3 is set on the side of the adjustment component 2 away from the conveying component 5. The adsorption component 3 can adsorb the input paper, reduce the paper input speed, and reduce the possibility of cardboard deviating.

[0076] The specific structure of adsorption component 3 is as follows: See Figures 9-11 The adsorption component 3 includes an air pump 31, and the air outlet of the air pump 31 is provided with a conduit 32. A suction cup 33 is provided at the end of the conduit 32 away from the air pump 31.

[0077] The air outlet of the air pump 31 is connected to the conduit 32, and the other end of the conduit 32 is connected to the suction cup 33. When the air pump 31 discharges air, the air inside the conduit 32 and the suction cup 33 will also be gradually drawn out. As air is continuously discharged, the air pressure inside the suction cup 33 will gradually be lower than the external atmospheric pressure, thus forming a pressure difference between the inside and outside of the suction cup 33.

[0078] Specifically, when cardboard needs to be adsorbed, the air pump 31 is started. The air pump 31 draws air out of the suction cup 33 through the conduit 32 to create an air pressure difference, thereby adsorbing the cardboard. When the cardboard needs to be released, the air pump 31 is stopped, allowing outside air to enter the suction cup 33 to balance the air pressure inside and outside the suction cup 33. The adsorption force disappears, and the object can be released. In this device, cardboard adsorption is only to reduce the possibility of cardboard drift, not to completely adsorb the cardboard and prevent it from moving. When the cardboard slows down due to adsorption, the conveying mechanism simultaneously conveys the cardboard so that it can reach the position of the adjusting component 2.

[0079] In practical applications, cardboard comes in various thicknesses. The suction effect is adjusted according to the thickness of the cardboard to better achieve adsorption. For thick cardboard, the air pump 31 is used at high power to increase the negative pressure of the suction cup 33, thereby increasing the adsorption force and reducing the possibility of the cardboard falling off. For thin cardboard, the power of the air pump 31 is reduced to decrease the negative pressure, thereby reducing the adsorption force and reducing the possibility of crushing the thin paper.

[0080] In practical applications, in addition to considering the thickness of the cardboard, the size of the cardboard also needs to be considered. When considering the size of the cardboard, the adjustment component 2 needs to be used to adapt to the change in size. When the position of the adjustment component 2 changes, the component set in front of the adjustment component 2 needs to change its position accordingly. That is, the adsorption component 3 also needs to adjust its position according to the size of the cardboard. In order to achieve the above purpose, the adsorption component 3 is further designed.

[0081] See Figures 9-11The adsorption component 3 also includes two sets of guide rails 39, which are arranged opposite to each other on the inner side wall of the conveyor frame 1. Each set of guide rails 39 has a set of sliders 38 on one side, and each set of sliders 38 has a set of mounting plates 37 on the side away from the guide rails 39. A fixing rod 35 is provided in the middle of the two sets of mounting plates 37, and a handle 301 is provided at one end of the fixing rod 35.

[0082] The fixed rod 35 is fixedly connected to the handle 301 and the mounting plate 37. In practical applications, pushing the handle 301 will cause the fixed rod 35 and the mounting plate 37 to move linearly along the guide rail 39.

[0083] Meanwhile, since the suction cup 33 is positioned in the middle of the two sets of mounting plates 37, and the suction cup 33 is fixedly connected to the two sets of mounting plates 37 respectively, the guide tube 32 is a flexible tube to accommodate the positional movement of the suction cup 33 as it moves with the mounting plates 37.

[0084] Specifically, in practical applications, the thickness of the cardboard is first determined, and then the operator adjusts the position of the suction cup 33 by using the handle 301 so that the suction cup 33 can adhere to the cardboard, reducing the possibility of cardboard drift.

[0085] See Figures 9-11 The suction cup 33 is provided with a first auxiliary roller 34 and a second auxiliary roller 36 on both sides. The second auxiliary roller 36 is located diagonally above the first auxiliary roller 34. The two ends of the first auxiliary roller 34 and the second auxiliary roller 36 are respectively fixedly connected to two sets of mounting plates 37.

[0086] Since the second auxiliary roller 36 and the first auxiliary roller 34 have a height difference, the second auxiliary roller 36 and the first auxiliary roller 34 form an inclined surface with a certain slope. When the cardboard is input from this surface, the cardboard can be smoothly input along the inclined surface due to the assistance of the slope of the second auxiliary roller 36 and the first auxiliary roller 34. Compared with a horizontally set plane, a plane with a certain slope is more conducive to the conveying of cardboard and improves the smoothness of the conveying.

[0087] Meanwhile, since the second auxiliary roller 36 and the first auxiliary roller 34 are respectively arranged on both sides of the suction cup 33, when the cardboard is attracted by the suction cup 33, the second auxiliary roller 36, the suction cup 33, and the first auxiliary roller 34 form an inclined plane, and the subsequent cardboard falls down in sequence. While being attracted, the cardboard is gradually transported by the conveying mechanism to the position of the adjusting component 2. During the gradual transport, the cardboard forms a fish scale-like stack at the position of the adjusting component 2. Compared with the fish scale effect formed by flat stacking, the inclined plane is more conducive to the arrangement of the cardboard.

[0088] Specifically, firstly, the cardboard is input from the position of the first auxiliary roller 34. At this time, the air pump 31 is started. Under the action of the air pump 31, the suction cup 33 begins to adsorb the cardboard and reduce the speed of the cardboard. Due to the position limitation of the second auxiliary roller 36, the suction cup 33, and the first auxiliary roller 34, the continuous cardboard is stacked in sequence. At the same time, the cardboard continues to be conveyed to the position of the adjustment component 2 under the drive of the conveying mechanism, and finally a fish scale stacking effect is formed at the position of the adjustment component 2.

[0089] In Example 3, the above structure provides a corresponding structural arrangement for the paperboard conveying process, enabling the paperboard to be input more smoothly into the position of the adjusting component 2. In addition to considering the paperboard input, it is also necessary to consider the paperboard's transfer from the position of the adjusting component 2 to the position of the conveying component 5. During the gradual conveying process, the paperboard has already formed a stack at the position of the adjusting component 2. In order not to damage the stacked effect of the paperboard, and to ensure that the paperboard enters the position of the conveying component 5 more smoothly, an auxiliary component 4 is set between the adjusting component 2 and the conveying component 5. The auxiliary component 4 can assist in achieving smoother paperboard conveying.

[0090] The specific structure of auxiliary component 4 is as follows: See Figure 12 and Figure 13 The auxiliary component 4 includes a connecting rod 44, on which several adjustment structures 45 are provided.

[0091] See Figure 12 and Figure 13 The auxiliary component 4 also includes a telescopic cylinder 41, which is disposed on the outer side wall of the conveyor frame 1. The output end of the telescopic cylinder 41 is connected to a connecting plate 42, which is T-shaped. The output end of the telescopic cylinder 41 is hinged to the connecting plate 42. The connecting plate 42 is fixedly connected to the connecting rod 44. The outer sides of both ends of the connecting rod 44 are respectively fitted with mounting seats 43, and the two sets of mounting seats 43 are respectively disposed on the outer side wall of the conveyor frame 1.

[0092] The specific movement process of auxiliary component 4 is as follows: When the telescopic cylinder 41 is activated, it drives the connecting plate 42 to swing. Under the drive of the connecting plate 42, the connecting rod 44 changes position with the connecting plate 42, and the adjusting structure 45 moves with the connecting rod 44. By adjusting the position of the adjusting structure 45, for example, when the initial position of the adjusting structure 45 is horizontal, when the telescopic cylinder 41 retracts, the adjusting structure 45 swings upward, and the cardboard on the adjusting structure 45 is lifted accordingly, providing a buffer time for the conveying of the front and rear cardboard. When the current cardboard is conveyed at the position of the conveying component 5, the rear cardboard is in a lifted state, and there is a time difference between the front and rear cardboard, which reduces the possibility of the rear cardboard directly impacting the front cardboard, and at the same time provides the possibility for the device to continuously stack cardboard.

[0093] See Figure 2 In addition, the adjustment structure 45 is located in the middle of the two sets of second pressure plates 2402. The length of the second pressure plate 2402 extends to the position of the conveying component 5. The second pressure plate 2402 can limit the paperboard, while not affecting the movement of the adjustment structure 45. The adjustment structure 45 lifts the paperboard, making it easier to convey the paperboard to the position of the conveying component 5.

[0094] Since the second pressure plate 2402 is a spring steel sheet, it is elastic when the adjustment structure 45 is raised, and will not affect the operation of the adjustment structure 45.

[0095] When the adjustment structure 45 is in a horizontal position, the position of the adjustment structure 45 can be changed under the action of the telescopic cylinder 41. In order to more smoothly achieve the lifting of the cardboard by the adjustment structure 45, the structure of the adjustment structure 45 can be further designed.

[0096] The specific structure of the adjustment structure 45 is as follows: See Figure 13 The adjustment structure 45 includes a first adjustment plate 451, which is fixedly connected to the connecting rod 44. A second adjustment plate 452 is provided at the end of the first adjustment plate 451 away from the connecting rod 44, and an angle is provided between the second adjustment plate 452 and the first adjustment plate 451.

[0097] In the initial position, the first adjusting plate 451 is horizontally placed. When the cardboard needs to be lifted, the first adjusting plate 451 tilts upward, and the cardboard above the first adjusting plate 451 is lifted along with the first adjusting plate 451. At this time, the lifting effect is further achieved by setting a second adjusting plate 452. If the second adjusting plate 452 is not set, there is no buffer between the cardboard and the first adjusting plate 451 when the first adjusting plate 451 is reset, and the cardboard will shake, affecting the stacking effect of the cardboard. By setting the second adjusting plate 452 at an angle to the first adjusting plate 451, the second adjusting plate 452 provides a buffer space for the cardboard, reducing the impact of the first adjusting plate 451 on the cardboard when it is reset, and reducing the possibility of cardboard misalignment.

[0098] Example 4: A stacking method using a continuous cardboard stacker, comprising the following steps: S1. First, adjust the positions of the adjustment component 2 and the adsorption component 3 according to the length, width and thickness of the cardboard. The cardboard is then input from the position of the adsorption component 3.

[0099] S11. Based on the length, width, and thickness of the cardboard, the operator operates the handle 301 to adjust the position of the suction cup 33 so that the suction cup 33 can adsorb the input cardboard. At the same time, based on the length, width, and thickness of the cardboard, the operator adjusts the position between the first adjustment mechanism 23 and the second adjustment mechanism 24 so that the second pressing plate 2402 and the first pressing plate 235 can flatten the cardboard.

[0100] S12. The cardboard is input through the suction cup 33. The suction cup 33 adsorbs the cardboard, reducing its speed. The cardboard is conveyed by the conveying mechanism while its speed is reduced.

[0101] S13. While the cardboard is being conveyed, the first pressing plate 235 adjusts its height under the action of the adjusting motor 237 to reduce the possibility of the first pressing plate 235 impacting the cardboard.

[0102] S2. Next, the cardboard input from the adsorption component 3 is gradually stacked in sequence at the position of the adjustment component 2 to form a fish scale pattern.

[0103] S21. Secondly, based on the position limitation of the cardboard by the second auxiliary roller 36, suction cup 33, and first auxiliary roller 34, and under the conveying of the conveying mechanism, the cardboard forms a fish-scale stacking effect at the middle position of the first adjusting mechanism 23 and the second adjusting mechanism 24.

[0104] S3. Then, the cardboard stacked at the position of the adjustment component 2 is assisted by the auxiliary component 4 to the position of the conveying component 5, and then conveyed by the conveying component 5 to the next station for packaging.

[0105] S31. The cardboard stacked at the positions of the first adjustment mechanism 23 and the second adjustment mechanism 24 is conveyed to the top of the adjustment structure 45 by the conveying mechanism. The telescopic cylinder 41 is activated. Under the action of the telescopic cylinder 41, the adjustment structure 45 drives the cardboard to rise, so that the cardboard can come into contact with the conveying component 5.

[0106] S32. After the cardboard comes into contact with the conveying component 5, it is gradually conveyed to the next station by the conveying component 5, and the cardboard is packaged at the next station.

[0107] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
