[0001] The invention relates to the technical field of corrugated paperboard drying and processing, and in particular to a corrugated paperboard production device and method. Background Art

[0002] Corrugated cardboard is a commonly used packaging material, which is widely used in the packaging industry due to its good cushioning performance, lightness and cost-effectiveness. Corrugated cardboard is composed of multiple layers of paper, at least one of which is specially treated to form a wavy corrugated paper to provide additional strength and cushioning performance; during the production of corrugated cardboard, multiple papers need to be glued together into a single cardboard. Glue is needed in the bonding process, so drying equipment is needed to dry and shape it.

[0048] Specifically, during the drying period, the driving motor 13 can drive one of the reciprocating screws 12 to rotate, and the forward reciprocating screw 12 will drive the other reciprocating screw 12 to rotate synchronously through the sprocket 30 and the chain 14 that cooperate with each other, thereby driving the slide 11 to slide back and forth in the processing box 2, and the slide 11 will drive the nozzle 7 and the nozzle 10 to slide back and forth in the processing box 2, and the nozzle 10 can dry the corrugated cardboard more comprehensively, so that the corrugated cardboard is dried more evenly, thereby ensuring the quality of the corrugated cardboard, and the corrugated cardboard stacked on each other subsequently is not prone to mutual adhesion.

[0049] Embodiment three:

[0050] Reference Figure 7 and Figure 8 , which is basically the same as the second embodiment, and further, a specific implementation scheme for lifting the nozzle 10 up and down is specifically added.

[0051] The above-mentioned slide 11 is provided with a longitudinal groove 15, and a lifting block 16 is longitudinally slidably installed in the longitudinal groove 15. The nozzle 7 is fixedly installed on the lifting block 16. A lifting part for reciprocating the lifting block 16 is provided in the processing box 2, and the lifting part includes an active protrusion 20 fixedly connected to the outer wall of the lifting block 16. A cross beam 18 parallel to the reciprocating screw 12 is fixedly connected in the processing box 2, and a plurality of driven protrusions 19 arranged at equal intervals are fixedly connected to the cross beam 18. The number of the driven protrusions 19 is 6-20, and the preferred number in this application is 16. When the active protrusion 20 follows the translation of the slide 11, the active protrusion 20 will press the plurality of driven protrusions 19 in turn, and a first spring 17 is installed between the lifting block 16 and the inner top of the longitudinal groove 15.

When the active protrusion 20 is not pressed, the first spring 17 will drive the lifting block 16 to slide in the opposite direction and reset. Therefore, under the action of the multiple driven protrusions 19, the lifting block 16 will slide up and down in the longitudinal groove 15, thereby driving the nozzle 7 and the nozzle 10 to slide up and down, and the nozzle 10 will indirectly approach and move away from the surface of the corrugated cardboard, thereby further increasing the exhaust area of ​​the nozzle 10, and the wind speed of the corrugated cardboard will be more dynamic, so that the drying effect of the corrugated cardboard is better.

[0053] Embodiment 4:

[0054] Reference Figure 6 , which is basically the same as the third embodiment, and further, a specific implementation scheme for making the corrugated cardboard swing back and forth is specifically added.

[0055] The inner wall of the above-mentioned processing box 2 is fixedly connected with a rotating shaft 24, and the middle part of the lower end of the rectangular frame 5 is fixedly connected to the rotating shaft 24. The interior of the processing box 2 is provided with a swinging part for driving the rectangular frame 5 to swing.

The inner wall of the processing box 2 is fixedly connected with a bracket 25, and a second spring 26 is installed between the two sides of the lower end of the rectangular frame 5 and the bracket 25.

[0056] When one of the reciprocating screws 12 rotates, it will also drive the cam 27 to rotate, and the cam 27 will indirectly lift one side of the rectangular frame 5. When one side of the rectangular frame 5 is lifted up, it will drive the rotating shaft 24 to rotate and make the other side swing downward. When the cam 27 stops lifting the rectangular frame 5, the second spring 26 will drive the rectangular frame 5 to swing back and forth to reset. Then the continuously rotating cam 27 will cause the rectangular frame 5 to swing back and forth, and the rectangular frame 5 will drive the corrugated cardboard to swing back and forth through the conveying roller 6. On the one hand, the corrugated cardboard can be dried more efficiently, and on the other hand, the debris generated during the drying of the corrugated cardboard can be shaken off, which is convenient for the subsequent stacking of the corrugated cardboard.

[0057] A method for producing corrugated paperboard, the operating steps are as follows:

[0058] Step 1: conveying the corrugated cardboard into the processing box 2 through the conveyor belt 4 on one side of the processing box 2;

[0062] Step 5: During the drying period, the corrugated cardboard is reciprocated in the processing box 2;

[0063] Step 6: The dried corrugated cardboard is discharged from the opening 3 through the conveyor roller 6 and the conveyor belt 4 .

[0064] When the corrugated cardboard production equipment is in use, the corrugated cardboard is conveyed into the processing box 2 by the conveyor belt 4 on one side of the processing box 2. After the corrugated cardboard enters the processing box 2, the corrugated cardboard is conveyed to the conveyor belt 4 on the other side by the conveyor roller 6. While the corrugated cardboard passes through the processing box 2, the hot air blower 8 is started, and the hot air blower 8 will convey hot air to the nozzle 7 through the hose 9. The two nozzles 7 symmetrically arranged up and down will blow the hot air to the surface of the corrugated cardboard through the nozzle 10, so that the corrugated cardboard can be dried. During the drying period, the hot air blower 8 is driven to blow hot air to the surface of the corrugated cardboard. The motor 13 can drive one of the reciprocating screws 12 to rotate, and the forward reciprocating screw 12 will drive the other reciprocating screw 12 to rotate synchronously through the sprocket 30 and the chain 14 that cooperate with each other, and then drive the slide 11 to slide back and forth in the processing box 2, and the slide 11 will drive the nozzle 7 and the nozzle 10 to slide back and forth in the processing box 2, and the nozzle 10 can dry the corrugated cardboard more comprehensively, so that the corrugated cardboard is dried more evenly, the quality of the corrugated cardboard is guaranteed, and the corrugated cardboards stacked on each other subsequently are not prone to mutual adhesion.

[0065] During the reciprocating sliding of the slide 11, the slide 11 will drive the lifting block 16 to slide synchronously, and the lifting block 16 will drive the active protrusion 20 to slide along the crossbeam 18. The multiple driven protrusions 19 will press the active protrusion 20 in turn. When the active protrusion 20 is pressed, it will drive the lifting block 16 to slide in the longitudinal groove 15 and squeeze the first spring 17. When the active protrusion 20 is not pressed, the first spring 17 will drive the lifting block 16 to slide in the opposite direction and reset. Therefore, under the action of the multiple driven protrusions 19, the lifting block 16 will slide up and down in the longitudinal groove 15, thereby driving the nozzle 7 and the nozzle 10 to slide up and down, and the nozzle 10 will indirectly approach and move away from the surface of the corrugated cardboard, thereby further increasing the exhaust area of ​​the nozzle 10, and the wind speed of the corrugated cardboard will be more dynamic, so that the drying effect of the corrugated cardboard is better.

[0066] When one of the reciprocating screws 12 rotates, it will also drive the cam 27 to rotate, and the cam 27 will indirectly lift one side of the rectangular frame 5. When one side of the rectangular frame 5 is lifted up, it will drive the rotating shaft 24 to rotate and make the other side swing downward. When the cam 27 stops lifting the rectangular frame 5, the second spring 26 will drive the rectangular frame 5 to swing back and forth to reset. Then the continuously rotating cam 27 will cause the rectangular frame 5 to swing back and forth, and the rectangular frame 5 will drive the corrugated cardboard to swing back and forth through the conveying roller 6. On the one hand, the corrugated cardboard can be dried more efficiently, and on the other hand, the debris generated during the drying of the corrugated cardboard can be shaken off, which is convenient for the subsequent stacking of the corrugated cardboard.

[0067] During the drying process, the exhaust fan 22 will suck air into the suction hood 21, and the suction hood 21 will suck air into the processing box 2 through the exhaust port 29, thereby absorbing the odor and paper scraps generated during the drying process, thereby ensuring the drying efficiency of the corrugated cardboard.
