Description

Technical Field

[0001] The present application relates to the technical field of conveying systems, and in particular to an automatic deviation-correcting device for conveying corrugated cardboard. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] During the production and processing of corrugated cardboard, it is usually necessary to transport the corrugated cardboard to a designated location so that the staff can package the corrugated cardboard. For example, in the related art, a Chinese patent with publication number CN113213234A proposes a corrugated cardboard automated production line conveying and correcting system, which has the advantages that when the corrugated cardboard deviates during movement, the corrugated cardboard collides with an adjustment frame, the adjustment frame drives the moving plate to move through the inclined structure during the collision process, and the corrugated cardboard is driven to reset through the correcting plate during the movement of the moving plate, and the corrugated cardboard is corrected, wherein the first spring rod, the second spring rod and the third spring rod reset the adjustment frame, the moving plate and the correcting plate during the working process, and the use of the guide plate enables the corrugated cardboard to move according to the corrected state to avoid the deflection again.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: corrugated cardboards usually need to be corrected during transportation to facilitate the stacking and packaging of subsequent corrugated cardboards, but the design is not convenient for correcting the deviation of multiple layers of corrugated cardboards at one time, resulting in the staff having to place the corrugated cardboards on the conveyor one by one for transportation and correction, which requires a lot of time to stack the corrugated cardboards, thereby affecting the progress of the corrugated cardboard packaging work. At the same time, it is not convenient to screen corrugated cardboards of different sizes, resulting in corrugated cardboards of different sizes being stacked together during stacking. The staff also needs to pull out the corrugated cardboards that are larger or smaller in size from the stacked corrugated cardboards in the subsequent order, which increases the labor intensity of the staff, is inconvenient to use, and cannot meet the actual use effect. Summary of the invention

[0005] In order to solve the problem that a correction device is not convenient for correcting the deviation of multiple layers of corrugated cardboard at one time, resulting in the staff having to place the corrugated cardboards one by one on the conveyor for conveyance and correction, which requires a lot of time to stack the corrugated cardboards, thereby affecting the progress of the corrugated cardboard packaging work, the present application provides an automatic correction device for conveying corrugated cardboards.

[0006] The present application provides an automatic deviation-correcting device for conveying corrugated cardboard, which adopts the following technical solution: An automatic deviation-correcting device for conveying corrugated cardboard, comprising a conveyor, a support frame fixed on the conveyor, an adjustment support plate lifted and arranged on the support frame, and a power member for lifting and rotating the adjustment support plate, the conveyor is provided with a conveyor belt for conveying multiple layers of the corrugated cardboard body, the conveyor is provided with a deviation-correcting mechanism for correcting the deviation of the multiple layers of the corrugated cardboard body, the deviation-correcting mechanism comprises a detection component for detecting the size of the multiple layers of the corrugated cardboard body and a clamping component for the multiple layers of the corrugated cardboard body; The detection assembly includes four adjustment plates lifted and arranged on the conveyor, and the four adjustment plates are each provided with a plurality of deflection correcting plates arranged at equal distances, and the plurality of deflection correcting plates are respectively movably fitted with the multi-layer corrugated cardboard body, and the four adjustment plates are respectively divided into two groups, and the two groups of adjustment plates are arranged relatively and located on the opposite sides of the corrugated cardboard body, and the adjustment support plate is provided with a translation member for synchronously and reversely translating the two groups of adjustment plates and a driving member for synchronously and reversely translating the two adjustment plates in each group, and a buffer member for buffering the deflection correcting plates is provided on the adjustment plate; The clamping assembly includes a plurality of limit clamps rotatably arranged on the adjustment plate, a rotating member for rotating and driving the plurality of limit clamps, and a power member for rotating and driving a designated limit clamp, and the plurality of limit clamps are respectively movably fitted with the multi-layer corrugated paperboard body; The plurality of deflection correcting plates and the plurality of position limiting clamping plates are respectively four groups, and the four groups of deflection correcting plates and the four groups of position limiting clamping plates are respectively arranged at equal distances on the four adjustment plates; The multi-layer corrugated paperboard body is corrected by a plurality of correcting plates and a plurality of limiting clamping plates on the four adjusting plates.

[0007] By adopting the above technical scheme, the power piece can sequentially drive the adjusting support plate and the correcting mechanism to perform lifting and lowering processing, and can also drive the adjusting support plate and the correcting mechanism to rotate the angle, so that the correcting mechanism can correct and clamp the width and length of the multi-layer corrugated cardboard body, so as to ensure the effect of conveying the subsequent multi-layer corrugated cardboard body, and at the same time ensure the effect of packaging the multi-layer corrugated cardboard body by the subsequent staff. The correcting mechanism can automatically correct and detect the multi-layer corrugated cardboard body, so that the multi-layer corrugated cardboard body can be kept flat and stacked. The clamping component can clamp the multi-layer corrugated cardboard body, so as to avoid the phenomenon that the width of the multi-layer corrugated cardboard body is offset when the length of the multi-layer corrugated cardboard body is corrected, and at the same time, the length of the multi-layer corrugated cardboard body is offset when the width of the multi-layer corrugated cardboard body is corrected. When correcting the existing corrugated cardboard, workers usually correct it one by one. The correction process of a single corrugated cardboard may be more time-consuming because each cardboard needs to be processed one by one, which affects the overall production efficiency. In order to achieve high-precision single correction, more complex equipment and control algorithms may be required, thereby increasing equipment costs. In addition, manual correction by workers requires more manpower and time, reducing production efficiency. Manual correction may be affected by human factors, such as fatigue and lack of concentration, resulting in reduced correction accuracy. For large-scale production lines, manual correction may increase the labor intensity and work pressure of workers. The detection component can be used to screen out the corrugated cardboard bodies with too small or too large length dimensions in the multi-layer corrugated cardboard bodies, and at the same time, the corrugated cardboard bodies with too small or too large width dimensions in the multi-layer corrugated cardboard bodies can be screened out, so that the staff can separately extract the model size that does not belong to this layer of corrugated cardboard bodies in the multi-layer corrugated cardboard bodies. At the same time, the detection component can make the multi-layer corrugated cardboard bodies have a buffering effect during deviation correction, so as to avoid the multi-layer corrugated cardboard bodies from being damaged due to excessive clamping force during deviation correction. The four sets of deviation correction plates and four sets of limit clamps can ensure the deviation correction effect of the multi-layer corrugated cardboard bodies.

[0009] By adopting the above technical scheme, the support plate, the driving motor, the adjusting support plate, the four adjusting plates, the four groups of correcting plates and the four groups of limiting clamps can be driven downward in turn by two hydraulic pumps, and the correcting plates and the limiting clamps at the bottom of each group can be moved to a position flush with the bottom corrugated cardboard body to ensure the correcting effect of the subsequent four groups of correcting plates and the four groups of limiting clamps on the multi-layer corrugated cardboard body. The adjusting support plate, the four adjusting plates, the four groups of correcting plates and the four groups of limiting clamps can be driven in turn by the driving motor to rotate ninety degrees, and the positions of the four groups of correcting plates and the four groups of limiting clamps can be reversed, so that the length and width of the multi-layer corrugated cardboard body can be corrected.

When the four groups of correcting plates fit with the side corners of the multi-layer corrugated cardboard body respectively, the multi-layer corrugated cardboard body can be automatically corrected, and the multi-layer corrugated cardboard body can be kept flat and stacked. By this method, multi-layer corrugated cardboard bodies of different models and sizes can be automatically corrected.

[0012] Optionally, the driving member includes threaded blocks fixed on four adjustment plates respectively, a bidirectional motor is arranged at the bottom of the adjustment support plate, two output shafts of the bidirectional motor are arranged with outer rods, the inner sides of the two outer rods are movably connected with inner rods, the outer sides of the two inner rods are arranged with first bevel gears, the outer sides of the two first bevel gears are meshed with second bevel gears, the inner sides of the two second bevel gears are arranged with bidirectional screws, each group of two threaded blocks are threadedly connected with two bidirectional screws respectively, and the inner side of the outer rod is arranged with a limiting member for limiting the inner rod.

At this time, the position of each group of multiple limiting round blocks can be observed. When one of the limiting round blocks in each group of multiple limiting round blocks does not change or moves in a large range, and is obviously inconsistent with the position of the other multiple limiting round blocks, it means that the size of the corresponding corrugated cardboard body is too small or too large, and does not belong to the model size of this layer of corrugated cardboard body. Therefore, the smaller or larger corrugated cardboard body needs to be pulled out separately.

[0016] Optionally, the rotating member includes a connecting wire fixed on a limiting clamp, a driving box is provided on the outer side of the adjusting plate, a first motor is provided on the top of the driving box, a rotating rod is provided on the output shaft of the first motor, a plurality of winding wheels are provided on the outer side of the rotating rod, a plurality of connecting wires are respectively wound around the outer sides of the plurality of winding wheels, a plurality of limiting clamps are hinged to the adjusting plate, a plurality of telescopic springs are provided on the outer sides of the limiting clamps, a plurality of telescopic springs are fixedly connected to the adjusting plate, a plurality of limiting wheels are provided on the outer side of the driving box, and a plurality of connecting wires slide on the plurality of limiting wheels respectively.

Moreover, through the elastic force of the multiple telescopic springs, the multiple limiting clamps can be rebounded respectively on the corners on both sides of the multi-layer corrugated cardboard body, so that the two sides of the multi-layer corrugated cardboard body can be limited, and the two sides of the multi-layer corrugated cardboard body can be corrected, thereby enhancing the automatic correction effect of the multi-layer corrugated cardboard body. At the same time, the phenomenon that the multi-layer corrugated cardboard body shakes left and right when the multi-layer corrugated cardboard body is corrected forward and backward can be avoided.

[0019] By adopting the above technical scheme, the threaded rod can be driven to rotate by the second motor, and the threaded push plate, the third motor and the movable hook rod can be driven to move up and down in turn, the position of the movable hook rod can be adjusted, and the movable hook rod can be moved to the connecting line at the corresponding position, and the movable hook rod can be driven to swing at a certain angle by the third motor, so that the movable hook rod can hook the connecting line, and at the same time, the connecting line can be pulled by the swing of the movable hook rod, and then the four limit clamps can be driven to return to the center respectively, and the movable hook rod releases the hooked connecting line, and at this time, the elastic force of the telescopic spring can drive the two limit clamps to rebound quickly respectively, so that the corrugated cardboard body that does not match the size and model can be pushed to the left, and one side of the corrugated cardboard body that does not match the size and model can be pushed out of the multi-layer corrugated cardboard body, thereby ensuring the effect of conveying and packaging of the subsequent corrugated cardboard body.

[0020] Optionally, the limiting member includes limiting blocks respectively fixed on the two inner rods, the inner sides of the two inner rods are provided with fixed square cavities, the two limiting blocks slide respectively on the inner sides of the two fixed square cavities, the inner sides of the two outer rods are respectively provided with rod holes with the same diameters as the two inner rods, the two outer rods are respectively slidably connected with the two rod holes, compression springs are provided on the two limiting blocks, arc blocks are provided on the outer sides of the two compression springs, arc grooves arranged at equal distances are provided on the inner sides of the two outer rods, and the multiple arc grooves are movably engaged with the arc blocks.

[0021] By adopting the above technical scheme, the two inner rods can be limited by the cooperation between the two limiting blocks, the two fixed square cavities, the two arc blocks, the two telescopic rods and the two compression springs to prevent the two inner rods from moving during rotation, so as to ensure the stability of the rotation of the two outer rods and the two inner rods. At the same time, when the two inner rods move in the two outer rods, the two arc blocks can be moved to the corresponding arc grooves respectively through the elastic force of the two compression springs, and the two inner rods and the two limiting blocks can be re-limited to ensure the rotation effect of the two inner rods.

[0022] Optionally, two supporting slide blocks are disposed on the top of the two movable frames, four supporting slide grooves are opened on the bottom of the adjusting support plate, and the four supporting slide blocks are slidably connected to the four supporting slide grooves respectively.

[0025] By adopting the above technical solution, the two hydraulic pumps, the drive motor, the bidirectional motor, the first motor, the second motor and the third motor can be driven in a timely manner through the intelligent controller to achieve automatic deviation correction and detection of the multi-layer corrugated cardboard body.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Place the multi-layer corrugated cardboard body to be packaged on the conveyor for transportation. When the corrugated cardboard body moves to the bottom of the adjustment support plate, the conveyor is temporarily stopped. The two hydraulic pumps can drive the support plate, the drive motor, the adjustment support plate, the two movable frames, the four adjustment plates, the four sets of correction plates and the four sets of limit clamps to move downward in sequence. Move the correction plates and limit clamps at the bottom of each group to a position flush with the bottom corrugated cardboard body. The two-way motor can drive the two outer rods, the two inner rods, the two first bevel gears, the two second bevel gears and the two bidirectional screws to rotate respectively, and then drive each group of two threaded blocks and each group of two adjustment plates to move relative or opposite to each other. According to the corrugated cardboard The distance between each group of two adjustment plates can be adjusted according to the length of the body. The four adjustment plates can be moved to the corners on the front and back sides of the corrugated cardboard body respectively to ensure the effect of the correction detection of multiple corrugated cardboard bodies in the subsequent sequence. After the position of each group of two adjustment plates is adjusted, the movable gear can be driven to rotate by the motor. When the movable gear rotates, it will drive two transmission racks, two movable frames and two groups of adjustment plates to move relatively. The multiple correction plates on the four adjustment plates will slowly fit with the multi-layer corrugated cardboard body in turn. When the four groups of correction plates fit with the front and back sides of the multi-layer corrugated cardboard body respectively, the multi-layer corrugated cardboard body can be automatically corrected, and the multi-layer corrugated cardboard body can be kept flat and stacked; 2. At the same time, when the four groups of deflection correction plates are respectively pressed against the multi-layer corrugated cardboard body, the four groups of buffer springs will be in a compressed state, which can then drive the four groups of active rods and the four groups of limit round blocks to move left and right. At this time, the position of each group of multiple limit round blocks can be observed. When one of the limit round blocks in each group of multiple limit round blocks does not change or moves too far, and is obviously inconsistent with the position of the other multiple limit round blocks, it means that the width of the corresponding corrugated cardboard body is too small or too large, and does not belong to the model size of this layer of corrugated cardboard body. Therefore, the corrugated cardboard body with a smaller or larger width model needs to be pulled out separately. At this time, the four first electric The machine can drive four rotating rods and four groups of take-up wheels to rotate clockwise respectively. When the four groups of take-up wheels rotate clockwise, the four groups of connecting wires can be released respectively, and the four groups of limit clamps can be rebounded on the left and right corners of the multi-layer corrugated cardboard body respectively through the elastic force of the four groups of telescopic springs, so that the left and right sides of the multi-layer corrugated cardboard body can be limited, and the left and right sides of the multi-layer corrugated cardboard body can be corrected, thereby enhancing the automatic correction effect of the multi-layer corrugated cardboard body. At the same time, the phenomenon that the multi-layer corrugated cardboard body shakes left and right when the multi-layer corrugated cardboard body is corrected forward and backward can be avoided, so as to ensure the correction effect of the multi-layer corrugated cardboard body forward and backward; 3. When it is necessary to take out the corrugated cardboard body that does not match the width size model in the multi-layer corrugated cardboard body, it is necessary to first pull back the four limit clamps that limit the corrugated cardboard body that does not match the width size model, and the four second motors can respectively drive the four threaded rods to rotate. When the four threaded rods rotate, they will respectively drive the four threaded push plates, the four third motors and the four movable hook rods to move up and down, and the positions of the four movable hook rods can be adjusted, and the four movable hook rods can be respectively moved to the four connecting lines at the positions corresponding to the four limit clamps. The four third motors can respectively drive the four movable hook rods to swing at a certain degree, and then the four movable hook rods can respectively hook the four connecting lines, and at the same time, through the swing of the four movable hook rods, the four connecting lines can be pulled respectively, and then the four limit clamps can be respectively driven to return to the positive position, so that the four limit clamps are respectively flush with the four adjustment plates. At this time, the two third motors on the right are driven to hook the two movable hook rods The two connecting lines taken out are loosened. At this time, the elastic force of the two telescopic springs can drive the two limiting clamps to rebound quickly, so that the corrugated cardboard body that does not match the width size model can be pushed to the left, and one side of the corrugated cardboard body that does not match the width size model can be pushed out of the multi-layer corrugated cardboard body, so that the staff can directly pull out the corrugated cardboard body that does not match the width size model, avoiding the subsequent staff from causing trouble in the classification and sorting of the multi-layer corrugated cardboard body. When the two limiting clamps on the right side push the corrugated cardboard body that does not match the width size model, because the two limiting clamps on the left side of the same layer are still in a state of being flush with the two adjustment plates on the left side, there will be no pushing interference. At the same time, all other limiting clamps are in a state of limiting the specified corrugated cardboard body. Therefore, when the corrugated cardboard body that does not match the width size model is pushed out, it will not drive other corrugated cardboard bodies to move, so as to ensure the stability of the stacking of the corrugated cardboard body and the effect of the subsequent corrugated cardboard body conveying and packaging; 4. After the front and rear sides of the corrugated cardboard body are accurately corrected, and after the corrugated cardboard bodies with smaller or larger width models are screened, when it is necessary to accurately correct the left and right sides of the corrugated cardboard body again, and when it is necessary to screen out the corrugated cardboard bodies with smaller or larger length models, first adjust the four groups of correction plates and the four groups of limit splints to the initial state through the above principle, move to the top of the multi-layer corrugated cardboard body, and then drive the adjustment support plate, two movable frames, four adjustment plates, four groups of correction plates and four groups of limit splints to rotate ninety degrees in turn through the driving motor, and reverse the positions of the four groups of correction plates and four groups of limit splints, so that the above principle is used again, and the four groups of correction plates and four groups of limit splints are driven to rise and fall by two hydraulic pumps, and the positions of the four adjustment plates, four groups of correction plates and four groups of limit splints can be adjusted through the drive of the bidirectional motor, the electric motor, the first motor, the second motor, the third motor and the intelligent controller, so that the left and right sides of the corrugated cardboard body can be accurately corrected, and at the same time The corrugated cardboard bodies with smaller or larger length models can be screened and processed, and the corrugated cardboard bodies with smaller or larger length models can be pulled out from the multi-layer corrugated cardboard bodies to ensure the stability of the correction of the multi-layer corrugated cardboard bodies, and at the same time, the effect of accurate screening of the multi-layer corrugated cardboard bodies can be enhanced. After the length and width of the multi-layer corrugated cardboard bodies are corrected, two hydraulic pumps are used to drive the lifting and lowering of four groups of correcting plates and four groups of limit clamps, and the positions of the four adjustment plates, four groups of correcting plates and four groups of limit clamps can be adjusted to the original positions through the drive of the bidirectional motor, the electric motor, the first motor, the second motor, the third motor and the intelligent controller, so that the four groups of correcting plates and the four groups of limit clamps are separated from the multi-layer corrugated cardboard bodies, so that the corrected multi-layer corrugated cardboard bodies can continue to be transported by the conveyor, so that the corrected multi-layer corrugated cardboard bodies can be transported to the designated location, so that the staff can pack the multi-layer corrugated cardboard bodies, and the correction device is convenient for correcting the multi-layer corrugated cardboard at one time.

[0039] The implementation principle of the automatic deviation-correcting device for conveying corrugated cardboard in the embodiment of the present application is as follows: (1) Place the multi-layer corrugated cardboard body 15 to be packaged on the conveyor 1 for conveying. When the corrugated cardboard body 15 moves to the bottom of the adjustment support plate 6, the conveyor 1 is temporarily stopped. The two hydraulic pumps 3 can sequentially drive the support plate 4, the drive motor 5, the adjustment support plate 6, the two movable frames 23, the four adjustment plates 14, the four groups of deflection correction plates 17 and the four groups of limit clamps 29 to move downward, and move the deflection correction plates 17 and the limit clamps 29 at the bottom of each group to a position flush with the bottom corrugated cardboard body 15; (2) The two outer rods 8, the two inner rods 9, the two first bevel gears 10, the two second bevel gears 11 and the two bidirectional screws 12 can be driven to rotate respectively by the bidirectional motor 7. When the two bidirectional screws 12 rotate, they can drive each group of two threaded blocks 13 and each group of two adjustment plates 14 to move relative to or away from each other. The distance between each group of two adjustment plates 14 can be adjusted according to the length of the corrugated cardboard body 15. The four adjustment plates 14 can be moved to the corners of the front and rear sides of the corrugated cardboard body 15 to ensure the effect of the correction detection of multiple corrugated cardboard bodies 15 in the subsequent order. (3) After the positions of the two adjustment plates 14 of each group are adjusted, the motor 20 can drive the movable gear 21 to rotate. When the movable gear 21 rotates, it will drive the two transmission racks 22, the two movable frames 23 and the two groups of adjustment plates 14 to move relative to each other. When the two groups of adjustment plates 14 move relative to each other, the multiple correction plates 17 on the four adjustment plates 14 will slowly fit with the multi-layer corrugated cardboard body 15 in sequence. When the four groups of correction plates 17 fit with the front and rear side corners of the multi-layer corrugated cardboard body 15 respectively, the multi-layer corrugated cardboard body 15 can be automatically corrected, and the multi-layer corrugated cardboard body 15 can be kept flat and stacked; (4) At the same time, when the four groups of deflection correction plates 17 are respectively pressed against the multi-layer corrugated cardboard body 15, the four groups of buffer springs 18 are in a compressed state, and then the four groups of movable rods 16 and the four groups of limiting round blocks 19 can be respectively driven to move left and right. At this time, the position of each group of multiple limiting round blocks 19 can be observed. When a certain limiting round block 19 in each group of multiple limiting round blocks 19 does not change or moves too far, and is obviously inconsistent with the position of the other multiple limiting round blocks 19, it means that the width of the corresponding corrugated cardboard body 15 is too small or too large, and does not belong to the model size of this layer of corrugated cardboard body 15. Therefore, the corrugated cardboard body 15 with a smaller or larger width model needs to be pulled out separately; (5) At this time, the four first motors 25 can respectively drive the four rotating rods 26 and the four groups of take-up wheels 27 to rotate clockwise. When the four groups of take-up wheels 27 rotate clockwise, the four groups of connecting wires 28 can be released respectively, and the four groups of limit clamps 29 can be respectively rebounded on the left and right corners of the multi-layer corrugated cardboard body 15 by the elastic force of the four groups of telescopic springs 30, so that the left and right sides of the multi-layer corrugated cardboard body 15 can be limited, and the left and right sides of the multi-layer corrugated cardboard body 15 can be corrected, thereby enhancing the automatic correction effect of the multi-layer corrugated cardboard body 15. At the same time, the phenomenon that the multi-layer corrugated cardboard body 15 shakes left and right when the multi-layer corrugated cardboard body 15 is corrected can be avoided, so as to ensure the correction effect of the multi-layer corrugated cardboard body 15; (6) When it is necessary to remove the corrugated cardboard body 15 of the multi-layer corrugated cardboard body 15 that does not conform to the width size model, the four limiting clamps 29 for limiting the corrugated cardboard body 15 that does not conform to the width size model need to be pulled back first, and the four second motors 32 can respectively drive the four threaded rods 33 to rotate. When the four threaded rods 33 rotate, they will respectively drive the four threaded push plates 34, the four third motors 35 and the four movable hook rods 36 to move up and down. The positions of the four movable hook rods 36 can be adjusted, and the four movable hook rods 36 can be moved to On the four connecting lines 28 at the positions corresponding to the four limit clamps 29, the four third motors 35 can respectively drive the four movable hook rods 36 to swing at a certain degree, and then the four movable hook rods 36 can respectively hook the four connecting lines 28, and at the same time, through the swing of the four movable hook rods 36, the four connecting lines 28 can be pulled respectively, and then the four limit clamps 29 can be respectively driven to return to the correct state, so that the four limit clamps 29 are respectively flush with the four adjustment plates 14. At this time, the two third motors 35 on the right are driven to The movable hook rod 36 releases the two hooked connecting wires 28. At this time, the elastic force of the two telescopic springs 30 can drive the two limit clamps 29 to rebound quickly, so that the corrugated cardboard body 15 that does not match the width size model can be pushed to the left, and one side of the corrugated cardboard body 15 that does not match the width size model can be pushed out of the multi-layer corrugated cardboard body 15, so that the staff can directly extract the corrugated cardboard body 15 that does not match the width size model, avoiding the trouble of the subsequent staff in sorting and arranging the multi-layer corrugated cardboard body 15. The two limit clamps 29 on the right side When the corrugated cardboard body 15 that does not conform to the width size model is pushed, because the two limiting clamps 29 on the left side of the same layer are still in a state of being flush with the two adjusting plates 14 on the left side, there will be no pushing interference, and at the same time all other limiting clamps 29 are in a state of limiting the specified corrugated cardboard body 15, so when the corrugated cardboard body 15 that does not conform to the width size model is pushed and pulled out, it will not drive other corrugated cardboard bodies 15 to move, so as to ensure the stability of the stacking of the corrugated cardboard bodies 15 and the effect of conveying and packaging the subsequent corrugated cardboard bodies 15; (7) After the front and rear sides of the corrugated cardboard body 15 are accurately corrected, and the corrugated cardboard bodies 15 with smaller or larger widths are screened out, when it is necessary to accurately correct the left and right sides of the corrugated cardboard body 15 again, and when it is necessary to screen out the corrugated cardboard bodies 15 with smaller or larger lengths, firstly, according to the above principle, the four sets of correcting plates 17 and the four sets of limit clamps 29 are adjusted to the initial state and moved to the top of the multi-layer corrugated cardboard body 15, and then the driving motor 5 can sequentially drive the adjustment support plate 6, the two movable frames 23, the four adjustment plates 14, the four sets of correcting plates 17 and the four sets of limit clamps 29 to rotate 90 degrees, and the positions of the four sets of correcting plates 17 and the four sets of limit clamps 29 are reversed, so as to be adjusted again by According to the above principle, the four groups of deflection correction plates 17 and the four groups of limit clamps 29 are driven to rise and fall by two hydraulic pumps 3, and the positions of the four adjustment plates 14, the four groups of deflection correction plates 17 and the four groups of limit clamps 29 are adjusted by driving the bidirectional motor 7, the electric motor 20, the first motor 25, the second motor 32, the third motor 35 and the intelligent controller 41, so that the left and right sides of the corrugated cardboard body 15 can be accurately corrected, and the corrugated cardboard body 15 with smaller or larger length models can be screened and processed, and the corrugated cardboard body 15 with smaller or larger length models can be extracted from the multi-layer corrugated cardboard body 15 to ensure the stability of the deflection correction of the multi-layer corrugated cardboard body 15, and the effect of accurate screening of the multi-layer corrugated cardboard body 15 can be enhanced; (8) After the length and width of the multi-layer corrugated cardboard body 15 are corrected, the two hydraulic pumps 3 are used to drive the four sets of correcting plates 17 and the four sets of limit clamps 29 to rise and fall, and the positions of the four adjustment plates 14, the four sets of correcting plates 17 and the four sets of limit clamps 29 can be adjusted to the initial positions through the driving of the bidirectional motor 7, the electric motor 20, the first motor 25, the second motor 32, the third motor 35 and the intelligent controller 41, so that the four sets of correcting plates 17 and the four sets of limit clamps 29 are separated from the multi-layer corrugated cardboard body 15, so that the corrected multi-layer corrugated cardboard body 15 can continue to be transported by the conveyor 1, so that the corrected multi-layer corrugated cardboard body 15 can be transported to the designated location, so that the staff can pack the multi-layer corrugated cardboard body 15; (9) When the driving motor 5 drives the two outer rods 8 and the two inner rods 9 to rotate, the two inner rods 9 can be limited by the cooperation between the two limiting blocks 37, the two fixed square cavities, the two arc blocks 39, the two telescopic rods 40 and the two compression springs 38 to prevent the two inner rods 9 from moving during rotation, thereby ensuring the stability of the rotation of the two outer rods 8 and the two inner rods 9; (10) At the same time, when the motor 20 and the movable gear 21 drive the two transmission racks 22 and the two movable frames 23 to translate, they will also drive the two inner rods 9 to slide in the two outer rods 8 respectively, and then push the two limit blocks 37 to slide in the inner sides of the two fixed square cavities respectively. When the two limit blocks 37 move, the two compression springs 38 will be in a compressed state, and then the two arc blocks 39 can be driven to move downward respectively, so that the two arc blocks 39 are separated from the two arc grooves currently engaged, so that the two limit blocks 37 and the two inner rods 9 lose their limit, avoiding the two inner rods 9 from being hindered when sliding, thereby ensuring the effect of the two inner rods 9 sliding in the two outer rods 8. At the same time, when the two inner rods 9 and the two limit blocks 37 move to the specified position, the elastic force of the two compression springs 38 can respectively move the two arc blocks 39 to the corresponding arc grooves respectively, and the two inner rods 9 and the two limit blocks 37 can be re-limited to ensure the effect of the two inner rods 9 rotating.

[0040] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of the correction device being convenient for correcting the deviation of multiple layers of corrugated cardboard at one time is achieved. The staff can put multiple corrugated cardboards on the conveyor 1 at one time for transportation and correction. The corrugated cardboards do not need to consume a lot of time when stacking, thereby improving the work progress of corrugated cardboard packaging. At the same time, it is convenient to screen corrugated cardboards of different sizes. When stacking corrugated cardboards, corrugated cardboards of different sizes are avoided from being stacked together. The staff does not need to pull out the corrugated cardboards with larger or smaller sizes from the stacked corrugated cardboards in the subsequent sequence, which reduces the labor intensity of the staff and meets the actual use effect.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
