Glue is applied to the top surface of the corrugated paper by a glue roller and spread evenly, and then the laminated surface and the cardboard are pressed together. The laminated corrugated cardboard enters the microwave drying device through the conveying device and is dried under the action of microwaves. The dried cardboard enters the flipping frame of the sheet stacker, and the sheet stacker stacks it vertically to form a paper stack, and the pores of the stacked corrugated cardboard all face the same side. Then the paper stack is conveyed into the moisture removal device. The rotary conveyor in the moisture removal device drives the paper stack to rotate horizontally, so that the pores of the corrugated cardboard on the paper stack face the air outlet of the moisture removal device, and the fan blows air on the paper stack for drying.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] Such as Figures 1 to 5As shown, it shows a color printing corrugated cardboard linkage production line body in an embodiment of the present invention, including a cardboard veneering device 1, a microwave drying device 2, a moisture exhaust device 3 for blowing and drying the laminated corrugated cardboard, a plurality of rotary shunting devices 9, a first logistics line 5, a second logistics line 6, and a die cutter 7 arranged in sequence; A paper stacker 8 is arranged between the microwave drying device 2 and the moisture exhaust device 3. The paper stacker 8 is used to vertically stack a plurality of dried corrugated cardboard sheets to form a paper stack, and the pores of the stacked corrugated cardboard sheets all face the same side; A rotary conveyor 4 is arranged in the moisture exhaust device 3. The rotary conveyor 4 can drive the paper stack to rotate horizontally so that the pores of the corrugated cardboard on the paper stack face the air outlet 1201 of the moisture exhaust device 3; Among them, the first logistics line 5 and the second logistics line 6 are connected end to end. The second logistics line 6 is used to temporarily store corrugated cardboard and / or convey corrugated cardboard to the die cutter 7. A plurality of rotary shunting devices 9 are respectively arranged at the connection of the first logistics line 5 and the second logistics line 6. The rotary shunting device 9 is used to convey the corrugated cardboard to the first logistics line 5 or the second logistics line 6.

[0026] For example, as Figure 1 shown, the color printing corrugated cardboard linkage production line body is overall linearly arranged, and each device is connected in sequence. The cardboard veneering device 1 is used to laminate the cardboard and the corrugated paper, and its internal is provided with mechanisms such as glue coating and pressing; The microwave drying device 2 is internally equipped with a microwave emitting device and a hollow conveyor belt; The moisture exhaust device 3 is internally provided with a rotary conveyor 4; The paper stacker 8 is located between the microwave drying device 2 and the moisture exhaust device 3, and includes components such as a frame 31, a driving chain, and a flipping frame 33; The rotary conveyor 4 is arranged in the moisture exhaust device 3; The first logistics line 5 is linear, and the second logistics line 6 is C-shaped. The two are connected end to end, and a plurality of rotary shunting devices 9 are arranged at the connection. The die cutter 7 is used to perform die cutting processing on the corrugated cardboard.

[0027] During operation, first, the cardboard and corrugated paper are separately placed on the cardboard conveyor and the veneering conveyor for transportation. Glue is applied to the top surface of the corrugated paper by a glue roller and spread evenly. Subsequently, the veneering and the cardboard are pressed together. The corrugated cardboard after pressing enters the microwave drying device 2 through the conveying device and is dried under the action of microwaves. The dried cardboard enters the turning frame 33 of the sheet stacker 8. The sheet stacker 8 stacks it vertically to form a paper stack, and the pores of the stacked corrugated cardboard all face the same side. Then the paper stack is transported to the moisture exhaust device 3. The rotary conveyor 4 in the moisture exhaust device 3 drives the paper stack to rotate horizontally, so that the pores of the corrugated cardboard on the paper stack face the air outlet 1201 of the moisture exhaust device 3, and the fan 12 blows air on the paper stack for drying. The dried paper stack is shunted by the rotary shunting device 9 and enters the first logistics line 5 or the second logistics line 6, and the second logistics line 6 temporarily stores the paper stack. When the paper loading device at the feeding end of the die cutter 7 needs a paper stack, the first logistics line 5 transports the paper stack to the paper loading device. After the paper loading device regularizes the paper stack, the paper loading machine 10 transports it to the die cutter 7 for die cutting processing. The cardboard after die cutting is output from the discharging end of the die cutter 7 for subsequent processing.

[0028] Through the linkage of each device, the production line realizes the automation of the corrugated cardboard box production process, shortens the production cycle, and improves the production efficiency. The cooperation between the sheet stacker 8 and the rotary conveyor 4 enables the pores of the corrugated cardboard to better align with the air outlet 1201 of the moisture exhaust device 3, enhances the dehumidification effect, and shortens the dehumidification time. The setting of the dual logistics lines and the rotary shunting device 9 improves the flexibility and reliability of the production line, and can reasonably allocate the cardboard conveying path according to the actual production situation, avoiding affecting the overall production due to the failure of a certain logistics line.

[0029] In some examples, the moisture exhaust device 3 includes a housing 40, and the rotary conveyor 4 is arranged in the middle inside the housing 40; there are two groups of fan groups, and the two groups of fan groups are symmetrically arranged on the two inner side walls of the housing 40. Each group of fan groups is provided with at least one fan 12, and the air outlets 1201 of the fans 12 all face the rotary conveyor 4. The rotary conveyor 4 can drive the paper stack to rotate horizontally by 90°, so that the pores of the corrugated cardboard face the air outlet 1201.

[0030] For example, as Figure 2 shown, the rotary conveyor 4 is arranged at the middle position inside the housing 40. The two groups of fan groups are symmetrically installed on the two inner side walls of the housing 40. Each group of fan groups can be provided with one or more fans 12 according to actual needs. The air outlets 1201 of the fans 12 all face the rotary conveyor 4, and the rotary conveyor 4 can drive the paper stack to rotate horizontally by 90°.

[0031] After the paper stack is conveyed onto the rotary conveyor 4 inside the moisture removal device 3, the rotary motor 42 of the rotary conveyor 4 starts, driving the rotary disk 41 to rotate, thereby horizontally rotating the paper stack by 90°, making the pores of the corrugated cardboard face the air outlet 1201 of the blower 12. At this time, the blower group is started, and the air blown by the blower 12 can directly act on the pores of the corrugated cardboard, accelerating the evaporation and discharge of the moisture inside the cardboard, and achieving effective drying of the paper stack.

[0032] Through the symmetrically arranged blower group and the rotatable rotary conveyor 4, the paper stack can be blown and dried from multiple directions, ensuring that all parts of the paper stack can be fully dried, improving the drying uniformity and efficiency, and further improving the moisture removal effect.

[0033] In some examples, the rotary conveyor 4 mainly consists of a rotary disk 41 and a conveying roller frame 43. A rotary motor 42 is installed on the rotary disk 41 for driving the rotary disk 41 to rotate; the conveying roller frame 43 is horizontally arranged on the rotary disk 41, and a number of rotating rollers 44 are horizontally arranged at intervals on the conveying roller frame 43. The rotating rollers 44 can freely rotate on the conveying roller frame 43 for carrying and conveying the paper stack.

[0034] For example, as Figure 2 shown, after the paper stack is conveyed onto the conveying roller frame 43, the rotary motor 42 starts, driving the rotary disk 41 to rotate, and further causing the conveying roller frame 43 and the paper stack to rotate horizontally together. During the rotation, the paper stack can be ensured to rotate smoothly, making the pores of the corrugated cardboard on the paper stack accurately face the air outlet 1201 of the moisture removal device 3.

[0035] In some examples, the sheet stacker 8 has a feed side 310 close to the microwave drying device 2 and a discharge side 311 close to the moisture removal device 3. At least one first driving chain 32 is vertically arranged on the inner wall of the frame 31 near the feed side 310, and a turning motor 34 is installed on the first driving chain 32; the turning frame 33 is arranged at the power output end of the turning motor 34. The turning frame 33 has an inlet 331 and an outlet, and is used for placing the dried corrugated cardboard inside; the paper stack conveyor 36 is arranged inside the frame 31 and close to the discharge side 311, and a wooden pallet is placed on the paper stack conveyor 36; two second driving chains 35 are vertically arranged on both sides of the inner wall of the frame 31 near the discharge side 311. The two second driving chains 35 are symmetrically arranged with respect to the paper stack conveyor 36 and are connected to the paper stack conveyor 36.

[0036] For example, as Figure 2As shown, the cardboard after microwave drying enters the inlet 331 of the flipping frame 33. The first electric push rod 371 is activated to drive the baffle 372 to move downward to block the inlet 331 and prevent the cardboard from falling. The first drive chain 32 drives the flipping motor 34 and the flipping frame 33 to move upward along the height direction of the frame 31. During the movement, the flipping motor 34 drives the flipping frame 33 and the cardboard inside to be vertically flipped by 180°. At the same time, a wooden pallet is placed on the paper stack conveyor 36. When the flipping frame 33 moves to a suitable position, the second electric push rod 39 drives the pusher plate 313 to move along the chute 332 on the flipping frame 33 through the inlet 331 in the direction of the outlet, pushing the corrugated cardboard in the flipping frame 33 onto the wooden pallet for stacking. After the stacking is completed, the second drive chain 35 drives the paper stack conveyor 36 and the wooden pallet to move upward, and the paper stack conveyor 36 transports the paper stack to the conveying device in the feeding direction of the moisture discharge device 3.

[0037] The paper stacker 8 realizes the automatic stacking and transfer of the dried corrugated cardboard through the coordinated work of multiple components, reduces manual operation, and improves production efficiency. The automatic flipping of the flipping frame 33 enables the cardboard to be stacked in a suitable posture, facilitating subsequent moisture discharge treatment and ensuring the stability of the paper stack.

[0038] In some examples, a rotating fixing member 37 is provided on the flipping frame 33. The rotating fixing member 37 is composed of the first electric push rod 371 and the baffle 372. The first electric push rod 371 is installed on the flipping frame 33, and the baffle 372 is arranged at the movable end of the first electric push rod 371. The size of the baffle 372 can completely block the inlet 331 and / or the outlet of the flipping frame 33.

[0039] For example, as Figure 4 shown, after the corrugated cardboard enters the flipping frame 33, the first electric push rod 371 is started. The movable end of the first electric push rod 371 drives the baffle 372 to move downward to block the inlet 331 and / or the outlet of the flipping frame 33. During the flipping process of the flipping frame 33, the baffle 372 can effectively prevent the cardboard from falling out of the flipping frame 33 and ensure the stability of the cardboard inside the flipping frame 33. When the flipping frame 33 completes the flipping and reaches the designated position, the first electric push rod 371 drives the baffle 372 to move upward to expose the inlet 331 and the outlet for subsequent pusher operations.

[0040] The setting of the rotating fixing member 37 improves the fixing effect of the flipping frame 33 on the cardboard during the flipping process, avoids the cardboard from falling, ensures the reliability and safety of the operation of the paper stacker 8, and is also conducive to improving the quality and efficiency of cardboard stacking.

[0041] In some examples, a chute 332 is provided on the upper edge of the flipping box 33 along the direction from the inlet 331 to the outlet. An installation seat 38 is installed on the inner top wall of the rack 31. A second electric push rod 39 is horizontally arranged on the installation seat 38. The movable end of the second electric push rod 39 is connected with a pushing plate 313. The size of the pushing plate 313 is adapted to the chute 332 and can slide freely in the chute 332.

[0042] For example, as Figure 2 shown, when the flipping box 33 moves upward to a specified position, the second electric push rod 39 is activated. The movable end of the second electric push rod 39 drives the pushing plate 313 to move along the chute 332 from the inlet 331 to the outlet direction. During the movement, the pushing plate 313 pushes out the corrugated cardboard in the flipping box 33, making it fall onto the wooden pallet of the paper stack conveyor 36 for stacking. By controlling the stroke and speed of the second electric push rod 39, the pushing position and quantity of the cardboard can be accurately controlled, ensuring the neatness of stacking. This makes the transfer process of the cardboard from the flipping box 33 to the wooden pallet more automated and precise, reduces manual intervention, improves the efficiency and quality of cardboard stacking, and at the same time enhances the stability and reliability of the operation of the sheet feeder 8.

[0043] In some examples, the first logistics line 5 is a straight conveyor belt structure, and the second logistics line 6 is C-shaped and surrounds one side of the first logistics line 5. Rotary diversion devices 9 are installed at the inflection points of the second logistics line 6. The rotary diversion device 9 consists of components such as a driving motor and a rotary tray, and can realize the turning and conveying of corrugated cardboard between the two logistics lines.

[0044] For example, as Figure 2 shown, the paper stack after being treated by the moisture removal device 3 is conveyed to the rotary diversion device 9. The rotary diversion device 9, according to the instructions of the control system, drives the driving motor to drive the rotary tray to rotate, and conveys the paper stack to the first logistics line 5. When one of the die cutters malfunctions, some paper stacks will be diverted to the second logistics line 6 for temporary storage until the malfunctioning die cutter resumes use; if both logistics lines are normal, they will be directly conveyed into the first logistics line. This layout of the logistics lines and the setting of the rotary diversion device 9 improve the flexibility and adaptability of the production line, can reasonably allocate the conveying path of the paper stack according to the actual production situation, avoid production stagnation caused by the malfunction of a certain logistics line, and at the same time, the temporary storage function of the second logistics line 6 can better coordinate the production rhythm between the die cutter 7 and other processes, improving the overall production efficiency.

[0045] In some examples, the paper loading device consists of a paper loading machine 10 and a regularizing plate 11. The paper loading machine 10 is arranged at the feeding port of the die cutter 7 for conveying the paper stack to the die cutter 7; several regularizing plates 11 are respectively installed on the two side walls of the paper loading machine 10, and the regularizing plates 11 can be adjusted in position and angle through an adjusting mechanism to adapt to paper stacks of different sizes and shapes.

[0046] For example, as Figure 1 shown, after the first logistics line 5 transports the paper stack to the paper loading machine 10, the regularizing plates 11 on both sides of the paper loading machine 10 regularize the paper stack. By adjusting the position and angle of the regularizing plates 11, the edges of the paper stack are made neat and the stack is tightly packed. After regularization, the paper loading machine 10 stably transports the paper stack to the feeding port of the die cutting machine 7, ensuring that the paper stack can accurately enter the die cutting machine 7 for processing. The setting of the paper loading device ensures that the paper stacks entering the die cutting machine 7 are neat and standardized, improving the processing accuracy and efficiency of the die cutting machine 7, reducing the processing errors and waste rate caused by irregular paper stacks, and at the same time extending the service life of the die cutting machine 7.

[0047] In some examples, the conveyor belt provided inside the microwave drying device 2 is of a hollow structure. The conveyor belt is composed of multiple hollow conveying units, and the conveying units are connected by connecting pieces to form a continuous conveying channel. This hollow design enables microwaves to better penetrate the corrugated cardboard, improving the drying effect. The corrugated cardboard after lamination is placed on the hollow conveyor belt. Driven by the driving device, the conveyor belt transports the cardboard into the microwave drying device 2. During the transportation process, the microwaves pass through the hollow parts of the conveyor belt and directly act on various parts of the corrugated cardboard, causing the moisture inside the cardboard to quickly evaporate, achieving rapid drying. The design of the hollow conveyor belt improves the penetrability of microwaves, enabling the corrugated cardboard to be dried more evenly and efficiently, shortening the drying time, improving the production efficiency, and at the same time ensuring the drying quality and avoiding problems such as cardboard deformation caused by uneven drying.

[0048] In addition, it should be noted that the cardboard pasting device 1 includes a cardboard conveyor. On the top of this cardboard conveyor, a face paper conveyor is installed, and a glue coating roller is provided inside the cardboard conveyor. At the same time, support columns are fixedly connected to the top of the pasting conveyor, and pressure wheels are installed at the bottom of the support columns. Inside the cardboard conveyor, a driving roller and a driven roller are also rotatably connected, and a motor is installed in the cardboard conveyor. The output shaft of the motor is fixedly connected to the driving roller. The positional relationship among the driving roller, the driven roller, and the pressure wheel: The driving roller and the driven roller are relatively close in position, and the distance between the bottom of the pressure wheel and the top of the conveyor belt inside the pasting conveyor is relatively close.

[0049] A method for the linked production of color-printed corrugated cartons includes the following steps: S1. Place the cardboard and the corrugated paper on the cardboard conveyor and the pasting conveyor respectively for transportation. Apply glue on the top surface of the corrugated paper, and the glue coating roller spreads the glue evenly. Then press the pasted surface and the cardboard together. The corrugated cardboard after lamination is transported into the microwave drying device 2 through the conveying device.

[0050] S2. The microwave drying device 2 performs microwave drying on the laminated cardboard, and the conveyor belt drives the cardboard to move inside the microwave drying device 2. The microwave emitting device inside the microwave drying device 2 emits microwaves to dry the laminated cardboard. The hollow conveyor belt drives the cardboard to move inside the microwave drying device 2, enabling all parts of the cardboard to fully receive microwave radiation and achieving uniform drying.

[0051] S3. The cardboard after microwave drying enters the turning frame 33 of the paper stacker 8. To prevent the cardboard from falling during the turning process, the first electric push rod 371 is activated to drive the baffle 372 to move downward, blocking the inlet 331 of the turning frame 33. The first driving chain 32 drives the turning frame 33 to move upward. During the movement, the turning motor 34 drives the turning frame 33 and the cardboard inside it to vertically turn 180°. At the same time, a wooden pallet is placed on the paper stack conveyor 36. When the turning frame 33 moves to a suitable position, the second electric push rod 39 drives the pushing plate 313 to move along the chute 332 on the turning frame 33 through the inlet 331 towards the outlet direction, pushing the cardboard in the turning frame 33 onto the wooden pallet for stacking. After stacking is completed, the paper stack conveyor 36 transports the paper stack to the conveying device in the feeding direction of the moisture exhaust device 3.

[0052] S4. After the paper stack is transported to the rotary conveyor 4 inside the moisture exhaust device 3, the rotary motor 42 of the rotary conveyor 4 is started, driving the rotary disk 41 and the paper stack to horizontally rotate 90°, making the pores of the corrugated cardboard face the air outlet 1201 of the blower 12. The blower unit is started, and the blower 12 blows air towards the paper stack, accelerating the discharge of moisture inside the cardboard and achieving the drying treatment of the paper stack.

[0053] S5. The paper stack after being processed by the moisture exhaust device 3 is shunted through the rotary shunting device 9. The paper stack is distributed into the first logistics line 5 and supplies materials to two die-cutting machines. When one of the die-cutting machines 7 breaks down, the rotary shunting device 9 will transport some corrugated cardboard into the second logistics line 6 for temporary storage until the faulty die-cutting machine 7 resumes operation again. If both the first logistics line 5 and the second logistics line 6 are normal, the paper stack will be transported into the first logistics line 5 in accordance with the preset sequence.

[0054] S6. When the paper stack feeding device at the feeding end of the die-cutting machine 7 needs a paper stack, the first logistics line 5 transports the paper stack to the paper stack feeding device according to the requirements of the paper stack feeding device. The regularizing plate of the paper stack feeding device regularizes the paper stack, and the paper stack feeding machine transports the regularized paper stack to the die-cutting machine.

[0055] S7. The die-cutting machine 7 performs die-cutting processing on the transported paper stack. According to the preset pattern and size, the cardboard is cut and indented by the cutter to form the preliminary shape of the corrugated cardboard box.

[0056] After die-cutting, the cardboard is conveyed out through the discharge end of the die-cutting machine 7 and enters the subsequent sorting and packaging processes, such as box nailing, box gluing, packing, etc., and finally forms the finished corrugated carton.

[0057] Through the reasonable planning of each production step and the coordinated cooperation of each device, this production method realizes the automation and high efficiency of color printing corrugated carton production. A series of processes from cardboard laminating, drying, stacking, moisture removal, shunting to die-cutting are closely connected, reducing manual intervention, improving production efficiency and product quality. At the same time, through the flexible scheduling of the double logistics line and the rotary shunting device 9, as well as the regular treatment of the paper stack by the paper loading device, the stability and reliability of the production process are ensured, and the production cost is reduced.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
