Description

Technical Field

[0001] The present application relates to the technical field of corrugated board drying control, and more specifically, to a method and device for controlling the drying of micro-corrugated board. Background Art

[0002] When corrugated products are produced, glue needs to be applied to the face paper and the core layer during the bonding process. Therefore, the moisture content of the entire corrugated product is relatively high after the face paper and the core layer are bonded. The high moisture content of corrugated products will cause the corrugated products to be too soft, resulting in a decrease in the edge pressure, tear resistance and other properties of the corrugated products. In addition, the surface paper of the corrugated products will bend during the drying process, affecting the subsequent die-cutting and other processes of the corrugated products. The moisture of corrugated products with higher flute heights (such as A flute and B flute) is easy to evaporate, but the moisture of micro-corrugated products (such as E flute, F flute, G flute) is difficult to evaporate due to its lower flute height. The existing method of accelerating the drying of micro-corrugated is to use a fan to blow air to the side of the corrugated to increase the amount of gas flowing into the corrugated, thereby taking away the moisture of the micro-corrugated. The height of micro-corrugated flutes is smaller, and the channels formed by the corrugated core layer of the corrugated flutes are smaller. The airflow blown into the corrugated flutes is difficult to pass through the channels formed by the corrugated core layer of the corrugated flutes, resulting in slow drying of the micro-corrugated flutes. In addition, the side of the flutes that is directly blown by the airflow dries too quickly, while the side without the airflow dries slowly, affecting the quality of the corrugated products.

[0003] For example, patent CN110749184B (application number: 201910895469.9) provides a dehumidification and drying system for a corrugated paper pile, wherein a blowing device for blowing air to the stacked corrugated paperboard is provided between the connecting plate and the clamping plate, and the blowing device includes a blower, an air duct and a branch pipe, wherein the blower is fixedly arranged on the connecting plate, the air duct is connected to the air outlet end of the blower, a plurality of branch pipes are provided and one end of each branch pipe is connected to the pipe mouth of the air duct, a plurality of ventilation holes are provided on the plate surface of the clamping plate, one end of the branch pipe is embedded in the ventilation hole, and the air flow is blown from the ventilation hole connected to the branch pipe to the side of the corrugated paperboard, thereby blowing and drying the side of the corrugated paper pile that conflicts with the clamping plate. However, due to the small size of the pipeline formed by the corrugated corrugated core layer, it is difficult for the drying system in patent CN110749184B to efficiently and stably dry micro-corrugated paper.

[0030] Since the channels formed by the corrugated core layer of the corrugated paper are relatively small, it is difficult for the drying system in the prior art to dry the micro-corrugated paper efficiently and stably.

[0031] Based on the above reasons, an embodiment of the present application provides a drying control method for micro-corrugated paper, which includes: performing suction drying on multiple corrugated stacks arranged in sequence, and obtaining a first outlet air humidity value of a first corrugated stack close to an air inlet of a drying airflow; wherein, multiple corrugated stacks are arranged in a corrugated drying duct, and negative pressure suction components and end drying components are respectively provided at both ends of the corrugated drying duct, and the corrugated core layer ducts of the multiple corrugated stacks are arranged along the length direction of the corrugated drying duct, and the negative pressure suction components suck the multiple corrugated stacks along the direction of the corrugated core layer duct, and the end drying component is used to supply a drying hot airflow to the corrugated drying duct; when the first outlet air humidity value is less than a preset first outlet air humidity value after a first time period, the drying airflow temperature value is controlled to be reduced and drying is continued for a second time period, and the first corrugated stack is discharged from the end where the end drying component is located. The drying control method for micro-corrugation in the embodiment of the present application can detect the outlet humidity of the first corrugated stack close to the air inlet of the drying air flow when controlling the negative pressure suction drying of the corrugated stacks when multiple corrugated stacks are dried, and reduce the temperature of the drying air flow according to the outlet humidity of the first corrugated stack, thereby ensuring that the humidity of the micro-corrugation after drying is within a predetermined range, while ensuring the efficiency of negative pressure suction drying of the micro-corrugation, improving the stability of the drying effect of the micro-corrugation and improving the drying effect of the corrugation.

[0032] In some scenarios, a micro-corrugated drying control method of an embodiment of the present application can be applied to the drying control of micro-corrugated sheets, which can prevent the micro-corrugated sheets from having excessively high or low humidity after drying, thereby improving the stability of the drying effect of the micro-corrugated sheets.

[0033] The following is a detailed description of a micro-corrugated drying control method provided in an embodiment of the present application with reference to specific examples.

[0034] Figure 1A schematic diagram of a drying control method for micro-corrugated sheets provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes S110 to S120, and S110 to S120 are described in detail below.

[0035] S110, performing suction drying on a plurality of corrugated stacks 1 arranged in sequence, and obtaining a first outlet humidity value of a first corrugated stack 11 near an air inlet of a drying airflow. The plurality of corrugated stacks 1 are arranged in a corrugated drying duct 2, and negative pressure suction components 21 and end drying components 22 are respectively provided at both ends of the corrugated drying duct 2. The corrugated core layer ducts of the plurality of corrugated stacks 1 are arranged along the length direction of the corrugated drying duct 2. The negative pressure suction components 21 suck the plurality of corrugated stacks 1 along the direction of the corrugated core layer ducts, and the end drying components 22 are used to supply a drying hot airflow to the corrugated drying duct 2.

[0036] When drying micro-corrugated sheets, it can be dried by negative pressure suction. Figure 2 A schematic diagram of the structure of a micro-corrugated drying device used in a micro-corrugated drying control method provided in an embodiment of the present application, as shown in FIG. Figure 2 As shown, the micro-corrugated drying equipment may include a corrugated drying pipe 2, which is a pipe for negative pressure suction drying of the micro-corrugated. During drying, the micro-corrugated is placed in the micro-corrugated drying pipe 2 and negative pressure suction is performed along the corrugated core layer pipe, so that the micro-corrugated can be dried by airflow through the corrugated core layer pipe.

[0037] Exemplarily, when drying the micro-corrugated sheets through the corrugated core layer pipe of the micro-corrugated sheets, a hot air flow may be introduced into the corrugated core layer pipe, thereby increasing the drying speed of the corrugated core layer pipe of the micro-corrugated sheets through the hot air flow.

[0038] like Figure 2 As shown, during corrugated cardboard drying, a plurality of corrugated cardboard stacks 1 are arranged in a corrugated cardboard drying duct 2, and a negative pressure suction component 21 and an end drying component 22 are respectively provided at both ends of the corrugated cardboard drying duct 2. The corrugated core layer ducts of the plurality of corrugated cardboard stacks 1 are arranged along the length direction of the corrugated cardboard drying duct 2, so that the airflow can pass through the corrugated core layer ducts of the plurality of corrugated cardboard stacks 1 to dry the plurality of corrugated cardboard stacks 1.

[0039] During operation, the negative pressure suction component 21 is used to suck multiple corrugated stacks 1 along the direction of the corrugated core layer pipe, so that the hot air flow can pass through the corrugated core layer pipes of multiple corrugated stacks 1 in sequence, and the end drying component 22 is used to supply drying hot air flow to the corrugated drying pipe 2.

[0040] Exemplarily, the negative pressure suction component 21 is a fan capable of generating negative pressure.

[0041] like Figure 2As shown, the end drying assembly 22 can evenly supply hot air flow to the end of the corrugated stack 1, so that the corrugated stack 1 can be evenly dried by the hot air flow.

[0042] Exemplarily, the end drying assembly 22 is a conveying pipe capable of supplying hot air flow to the end of the corrugated stack 1.

[0043] like Figure 2 As shown, the micro-corrugated drying duct 2 can be made by covering a flexible fiber cloth on a bracket, and the distance between the micro-corrugated drying duct 2 and the multiple corrugated stacks 1 is 1 cm to 2 cm. When the multiple corrugated stacks 1 are sucked by negative pressure, the flexible fiber cloth on the micro-corrugated drying duct 2 adheres to the multiple corrugated stacks 1 under the action of negative pressure to seal the circumference of the multiple corrugated stacks 1, so that the airflow can pass through the corrugated core layer ducts of the multiple corrugated stacks 1 to dry the multiple corrugated stacks 1.

[0044] like Figure 2 As shown, during drying, a plurality of corrugated stacks 1 arranged in sequence can be suction dried, and hot air flow passes through the corrugated core layer pipe to dry the micro-corrugated.

[0045] like Figure 2 As shown, during drying, the corrugated stack is fed from one end of the micro-corrugated drying duct 2 close to the negative pressure suction assembly 21, and discharged from one end of the micro-corrugated drying duct 2 close to the end drying assembly 22. During operation, the humidity of the corrugated stack gradually decreases from the negative pressure suction assembly 21 to the end drying assembly 22, which can ensure the drying efficiency and dryness when discharging, that is, the corrugated stack is pre-dried and dried from the negative pressure suction assembly 21 to the end drying assembly 22, which ensures the drying efficiency and dryness when discharging.

[0046] Exemplarily, when the corrugated stack 1 is fed and unloaded on the micro-corrugated drying pipe 2, the corrugated stack 1 can be transported by rollers that simultaneously perform transverse and longitudinal transport; when the corrugated stack 1 is transported on the micro-corrugated drying pipe 2, the corrugated stack 1 can be transported by longitudinal transport rollers.

[0047] During use, the first outlet air humidity value of the first corrugated stack 11 near the drying air inlet can be obtained. The first corrugated stack 11 is the corrugated stack waiting for discharge. The first outlet air humidity value can be used to determine whether the first corrugated stack 11 can be discharged.

[0048] S120, when the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, control to reduce the drying air flow temperature value and continue drying for the second time period, and discharge the first corrugated stack 11 from the end where the end drying component 22 is located.

[0049] In an embodiment of the present application, when the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, the preset first outlet air humidity value corresponds to the outlet humidity of the first corrugated stack 11 when it is close to being discharged. At this time, the drying air flow temperature value can be controlled to be reduced and the drying can be continued for the second time period, which can reduce the drying speed of the first corrugated stack 11, that is, the drying speed of the first corrugated stack 11 in the first time period is greater than the drying speed of the first corrugated stack 11 in the second time period, which can avoid over-drying of the first corrugated stack 11 and ensure the stability of the drying quality of the first corrugated stack 11.

[0050] After the second time period, the first corrugated stack 11 can be discharged from the end where the end drying component 22 is located, and subsequently multiple corrugated stacks 1 can be transported by the conveying component, and the corrugated stacks can be fed from the end where the negative pressure suction component 21 is located, so as to realize continuous drying of the corrugated stacks.

[0051] The beneficial effect brought by the above implementation method is that when the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, the drying speed of the first corrugated stack can be reduced to avoid overdrying of the first corrugated stack, thereby ensuring the stability of the drying quality of the first corrugated stack.

[0052] In some implementations, the above method further includes S210 to S220, and S210 to S220 are described in detail below.

[0053] S210, obtaining a second outlet air humidity value of a second corrugated stack 12 close to the suction outlet.

[0054] During drying, the second outlet air humidity value of the second corrugated stack 12 near the suction outlet can also be obtained, so as to evaluate the drying condition of the corrugated stack in the middle of the micro-corrugated drying duct 2, thereby facilitating the adjustment of the drying effect of the corrugated stack in the middle of the micro-corrugated drying duct 2 and improving the drying effect of multiple corrugated stacks 1 in the middle of the micro-corrugated drying duct 2.

[0055] S220: When the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, and the second outlet air humidity value is greater than the preset second outlet air humidity value, a drying hot air flow is supplemented between the multiple corrugated stacks 1 from the side of the corrugated drying pipe 2 through the lateral drying component 23 during the second time period.

[0056] During the drying process, when the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, it indicates that the first corrugated stack 11 is close to the outlet air humidity at the time of discharge. At this time, when the second outlet air humidity value is greater than the preset second outlet air humidity value, it indicates that the humidity of the multiple corrugated stacks 1 in the middle of the micro-corrugated drying pipe 2 is relatively high. At this time, the lateral drying component 23 can be used to supplement the supply of drying hot air flow between the multiple corrugated stacks 1 from the side of the corrugated drying pipe 2 during the second time period, and then the drying hot air flow can be supplemented from the side of the corrugated drying pipe 2 to the multiple corrugated stacks 1, thereby ensuring the drying effect of the multiple corrugated stacks 1 in the middle of the micro-corrugated drying pipe 2.

[0057] like Figure 2 As shown, the lateral drying component 23 supplies a supplementary drying hot air flow between the plurality of corrugated stacks 1 from the side of the corrugated drying pipe 2. The lateral drying component 23 may be a component that supplies a hot air flow through a pipe.

[0058] Exemplarily, the lateral drying components 23 may be disposed on both sides or the top of the corrugated drying duct 2 .

[0059] The beneficial effect brought about by the above-mentioned implementation method is that, in the process of reducing the temperature value of the drying airflow and continuing to dry for the second time period, by reducing the drying speed of the first corrugated stack, the drying hot airflow can be supplemented to multiple corrugated stacks from the side of the corrugated drying pipe, thereby ensuring the drying effect of multiple corrugated stacks in the middle of the micro-corrugated drying pipe.

[0060] In some implementations, in the above S110, obtaining the first outlet air humidity value of the first corrugated stack 11 near the drying air inlet includes: obtaining multiple first local outlet air humidity values ​​at different outlets of the corrugated core layer duct of the first corrugated stack 11. The multiple first local outlet air humidity values ​​are detected by multiple wireless humidity sensors 111 disposed at different outlets of the corrugated core layer duct of the first corrugated stack 11.

[0061] Figure 3 A schematic diagram of the partial structure of a micro-corrugated drying device used in a micro-corrugated drying control method provided in an embodiment of the present application, Figure 4 for Figure 3 The schematic diagram of the local structure of the micro-corrugated drying equipment at A. Figure 5 FIG. 1 is a schematic diagram of the end structure of the first corrugated stack of a micro-corrugated drying device in an embodiment of the present application, such as Figures 3 to 5As shown, in order to accurately measure the first outlet air humidity value of the first corrugated stack 11, a plurality of wireless humidity sensors 111 can be arranged at the end of the first corrugated stack 11, so as to facilitate detection of a plurality of first local outlet air humidity values ​​at different air outlets of the corrugated core layer duct of the first corrugated stack 11 by the plurality of wireless humidity sensors 111, and subsequently the accuracy of the first outlet air humidity value of the first corrugated stack 11 can be improved by the plurality of first local outlet air humidity values.

[0062] Exemplarily, the wireless humidity sensor 111 can be inserted between multiple corrugated boards of the corrugated stack 1 through an insertion plate. The wireless humidity sensor 111 is inserted on the corrugated stack 1 before feeding the corrugated stack, so as to detect the exhaust humidity of the corrugated stack 1.

[0063] Exemplarily, the plurality of wireless humidity sensors 111 are disposed at four corner points of the first corrugated stack 11 and a center point of the first corrugated stack 11 .

[0064] In some implementations, in the above-mentioned S120, the first outlet air humidity value is less than the preset first outlet air humidity value, including: determining that each first local outlet air humidity value is less than a first number of the preset first outlet air humidity value, and when the first number is greater than the preset first number, determining that the first outlet air humidity value is less than the preset first outlet air humidity value.

[0065] During use, after obtaining multiple first local outlet air humidity values ​​at different air outlets of the corrugated core layer duct of the first corrugated stack 11, a preset first outlet air humidity value can be used as a benchmark value. The preset first outlet air humidity value is the outlet air humidity when the first corrugated stack 11 is close to discharging. The preset first outlet air humidity value and the first local outlet air humidity value are compared, and then a first number of each first local outlet air humidity value less than the preset first outlet air humidity value can be determined. When the first number is greater than the preset first number, it means that a large number of first local outlet air humidity values ​​are less than the preset first outlet air humidity value, and then it can be determined that the first outlet air humidity value is less than the preset first outlet air humidity value.

[0066] Exemplarily, the preset first number may be 50% to 60% of the number of the plurality of wireless humidity sensors 111 at different air outlets of the corrugated core layer ducts of the first corrugated stack 11 .

[0067] The beneficial effect brought about by the above-mentioned implementation method is that by determining that each first local outlet air humidity value is less than a first number of preset first outlet air humidity values, and when the first number is greater than the preset first number, determining that the first outlet air humidity value is less than the preset first outlet air humidity value, the outlet air humidity value of the first corrugated stack can be accurately detected, thereby avoiding accidental errors caused by failure of individual wireless humidity sensors.

[0068] The beneficial effect brought about by the above-mentioned implementation method is that, when the first number is greater than the preset first number, it is determined that the first outlet air humidity value is less than the preset first outlet air humidity value, and the dryness of the first corrugated stack can be comprehensively evaluated according to the number of first local outlet air humidity less than the preset first outlet air humidity value, thereby avoiding the influence of the outlet air humidity detection result caused by the fluctuation of the local drying effect, and improving the comprehensiveness of the outlet air humidity detection of the first corrugated stack.

[0069] In some implementations, in the above S210, obtaining the second outlet air humidity value of the second corrugated stack 12 near the suction outlet includes: obtaining multiple second local outlet air humidity values ​​at different outlets of the corrugated core layer duct of the second corrugated stack 12. The multiple second local outlet air humidity values ​​are detected by multiple wireless humidity sensors 111 disposed at different outlets of the corrugated core layer duct of the second corrugated stack 12.

[0070] Similarly, multiple wireless humidity sensors 111 can be set at different air outlets of the corrugated core layer duct of the second corrugated stack 12, and multiple second local outlet air humidity values ​​can be detected by multiple wireless humidity sensors 111 to obtain multiple second local outlet air humidity values ​​at different air outlets of the corrugated core layer duct of the second corrugated stack 12, and the dryness of the second corrugated stack 12 can be determined by the multiple second local outlet air humidity values.

[0071] In some implementations, in the above-mentioned S220, the second outlet air humidity value is greater than the preset second outlet air humidity value, including: determining that each second local outlet air humidity value is greater than a second number of the preset second outlet air humidity value, and when the second number is greater than the preset second number, determining that the second outlet air humidity value is greater than the preset second outlet air humidity value.

[0072] Similarly, when determining whether the second outlet air humidity value is greater than the preset second outlet air humidity value, it can be determined that each second local outlet air humidity value is greater than a second number of the preset second outlet air humidity value. When the second number is greater than the preset second number, it is determined that the second outlet air humidity value is greater than the preset second outlet air humidity value.

[0073] Exemplarily, the preset second number may be 50% to 60% of the number of the plurality of wireless humidity sensors 111 at different air outlets of the corrugated core layer ducts of the second corrugated stack 12 .

[0074] The beneficial effect brought about by the above implementation method is that the humidity value of the outlet air of the second corrugated stack can be accurately detected, thereby avoiding accidental errors caused by failure of individual wireless humidity sensors.

[0075] The beneficial effect brought about by the above implementation method is that the influence of the fluctuation of the local drying effect on the detection result of the outlet air humidity is avoided, and the comprehensiveness of the detection of the outlet air humidity of the first corrugated stack is improved.

[0076] In some implementations, in the above-mentioned S220, when the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, and the second outlet air humidity value is greater than the preset second outlet air humidity value, the lateral drying component 23 is used to supplement the supply of drying hot air flow between multiple corrugated stacks 1 from the side of the corrugated drying pipe 2 during the second time period, including S221 to S222, and S221 to S222 are specifically described below.

[0077] S221. Determine a difference between a second outlet air humidity value and a preset second outlet air humidity value as an intermediate outlet air humidity difference.

[0078] When the corrugated paper is dried, the flow rate and temperature of the hot air flow when the hot air flow is supplemented by the lateral drying assembly 23 can be further determined to improve the supplementary drying effect. During drying, the difference between the second outlet air humidity value and the preset second outlet air humidity value can be determined as the intermediate outlet air humidity difference, and the flow rate and temperature of the supplementary hot air flow can be controlled according to the intermediate outlet air humidity difference.

[0079] S222. Determine, according to the intermediate outlet air humidity difference, a supplementary hot air flow rate and a supplementary hot air temperature value corresponding to the hot air flow supplemented by the lateral drying assembly 23 during the second time period.

[0080] During operation, the corresponding supplementary hot air flow rate and supplementary hot air flow temperature value when the hot air flow is supplemented by the lateral drying component 23 during the second time period can be determined according to the difference in humidity of the middle air outlet, and then the supplementary hot air flow rate and the supplementary hot air flow temperature value can be controlled to ensure the drying effect of the corrugated stack in the middle by the supplementary hot air flow supplied by the lateral drying component 23.

[0081] The beneficial effect brought about by the above-mentioned implementation method is that the flow rate of the supplementary hot air flow and the temperature value of the supplementary hot air flow are controlled according to the difference between the second outlet air humidity value and the preset second outlet air humidity value, thereby ensuring the drying effect of the corrugated stack in the middle by supplementing the hot air flow supplied by the lateral drying component.

[0082] In some implementations, in the above S220, when the first outlet air humidity value is less than the preset first outlet air humidity value after the first time period, and the second outlet air humidity value is greater than the preset second outlet air humidity value, in the second time period, the lateral drying component 23 is used to supplement the supply of drying hot air flow between the multiple corrugated stacks 1 from the side of the corrugated drying pipe 2, and also includes: according to the ratio of the duration of the first time period to the second time period, the supplementary hot air flow is distributed to the first time period and the second time period to supplement the supply of drying hot air flow respectively.

[0083] When drying corrugated paper, in order to improve the drying effect of the corrugated paper, the ratio of the duration of the first time period and the second time period can be determined, and the supplementary hot air flow rate can be distributed to the first time period and the second time period to respectively supplement the supply of drying hot air flow, so that the middle corrugated stack can be dried by supplementing the hot air flow through the lateral drying component within the time length of the first time period and the second time period, thereby improving the moisture removal effect of multiple corrugated stacks and improving the drying effect of the corrugated stacks.

[0084] Exemplarily, when the ratio of the duration of the first time period to the second time period is 6:4, the supplementary hot air flow rate can be allocated to the first time period and the second time period in a ratio of 6:4 to supplement the drying hot air flow.

[0085] The beneficial effect brought about by the above implementation method is that during the first time period and the second time period, the side drying component supplements the supply of hot air flow to dry the middle corrugated stack, thereby improving the moisture removal effect of multiple corrugated stacks and improving the drying effect of the corrugated stacks.

[0086] In some implementations, the above method further includes S310 to S320, and S310 to S320 are described in detail below.

[0087] S310, obtaining the first corrugation height of the first corrugated stack 11 discharged from the end where the end drying component 22 is located, and obtaining the third corrugation height and the third corrugation moisture content of the third corrugated stack 13 entering from the end where the negative pressure suction component 21 is located.

[0088] When drying corrugated paper, it is often necessary to change the height of the corrugated paper, for example, changing the corrugated paper from E corrugated paper to F corrugated paper, because the drying effect of corrugated paper with different corrugated heights is different. Therefore, in order to ensure the drying effect when changing the height of the corrugated paper, the first corrugated height of the first corrugated paper stack 11 discharged from the end where the end drying component 22 is located can be obtained, and the third corrugated height and third corrugated moisture content of the third corrugated paper stack 13 entering from the end where the negative pressure suction component 21 is located can be obtained, and then the parameters of the side drying component 23 supplementing the hot air flow can be adjusted according to the first corrugated height, the third corrugated height and the third corrugated moisture content.

[0089] S320, when the third corrugation height is different from the first corrugation height, the supplementary hot air flow rate is corrected according to the moisture content of the third corrugation and the third corrugation height to obtain a first corrected hot air flow rate, and the hot air flow is supplemented through the lateral drying component 23 according to the first corrected hot air flow rate.

[0090] During operation, when the height of the third corrugation is different from the height of the first corrugation, the supplementary hot air flow rate can be corrected according to the moisture content of the third corrugation and the third corrugation height to obtain the first corrected hot air flow rate, and the hot air flow can be supplemented through the lateral drying component 23 according to the first corrected hot air flow rate, thereby ensuring the subsequent drying effect of the third corrugated stack with the third corrugation moisture content and the third corrugation height.

[0091] The beneficial effect brought about by the above implementation method is that the flow rate of the supplementary hot air flow is corrected according to the moisture content of the third corrugated stack and the height of the third corrugated stack, thereby ensuring the drying effect of the corrugations when the height of the corrugations changes.

[0092] The beneficial effect brought about by the above implementation method is that when the third corrugated stack enters the corrugated drying pipeline, the supplementary hot air flow rate can be corrected during the pre-drying stage of the third corrugated stack, thereby ensuring the subsequent drying effect of the third corrugated stack after the corrugation height changes.

[0093] In some implementations, the above method further includes S410 to S420, and S410 to S420 are described in detail below.

[0094] S410, after the first corrugated stack 11 is discharged, the hot air flow is supplemented for a third time period through the lateral drying assembly 23 according to the first corrected hot air flow rate, and a second corrected outlet air humidity value of the second corrugated stack 12 is obtained. The third time period is smaller than the second time period.

[0095] After the height of the corrugated paper changes, when the corrugated paper is dried by the first corrected hot air flow rate, the drying effect of the first corrected hot air flow rate can also be monitored to ensure the drying effect on the corrugated paper stack.

[0096] During drying, after the first corrugated stack 11 is discharged, the hot air flow is supplemented through the lateral drying component 23 for a third time period according to the first corrected hot air flow rate, and the second corrected outlet air humidity value of the second corrugated stack 12 can be obtained, and then the drying effect of the lateral drying component 23 can be detected according to the second corrected outlet air humidity value after the third time period.

[0097] When obtaining the second corrected outlet air humidity value, the third time period is smaller than the second time period, so that the drying effect of the first corrected hot air flow rate can be monitored.

[0098] S420. When the second corrected outlet air humidity value is greater than the preset corrected outlet air humidity value, the first corrected hot air flow rate is corrected according to the third corrugation height and the first corrugation height to obtain a second corrected hot air flow rate, and the hot air flow is supplemented by the lateral drying component 23 during the remaining time of the second time period according to the second corrected hot air flow rate.

[0099] When monitoring the drying effect of the first corrected hot air flow rate, when the second corrected outlet air humidity value is greater than the preset corrected outlet air humidity value, it indicates that the supplementary drying effect of the corrugated stack is not good. At this time, the first corrected hot air flow rate can be corrected according to the third corrugation height and the first corrugation height to obtain the second corrected hot air flow rate, thereby realizing a further correction of the first corrected hot air flow rate.

[0100] During drying, the hot air flow can be supplemented by the lateral drying assembly 23 during the remaining time of the second time period according to the second corrected hot air flow rate, thereby ensuring the supplementary drying effect of the corrugated stack after the height change during the remaining time of the second time period.

[0101] Exemplarily, the preset corrected outlet air humidity value may be 50% to 60% of the preset second outlet air humidity value.

[0102] The beneficial effect brought about by the above implementation method is that the drying effect of the first corrected hot air flow rate is monitored and the first corrected hot air flow rate is corrected again, thereby ensuring the supplementary drying effect of the corrugated stack after the height change within the remaining time of the second time period.

[0103] In some implementations, in the above-mentioned S420, the first corrected thermal air flow rate is corrected according to the third corrugation height and the first corrugation height to obtain the second corrected thermal air flow rate, including: determining the corrugation height ratio of the first corrugation height and the third corrugation height, multiplying the corrugation height ratio and the first corrected thermal air flow rate to obtain the second corrected thermal air flow rate.

[0104] When adjusting the first corrected hot air flow rate, the corrugated height ratio of the first corrugated height and the third corrugated height can be determined, and the corrugated height ratio is multiplied by the first corrected hot air flow rate to obtain the second corrected hot air flow rate, thereby realizing the adjustment of the drying effect of the corrugated stack based on the first corrugated height and the third corrugated height.

[0105] Exemplarily, when the third corrugation height is less than the first corrugation height, the corrugated core layer duct of the third corrugated stack corresponding to the third corrugation height is lower and has a greater wind resistance. At this time, the corrugation height ratio and the first corrected hot air flow rate can be multiplied, and the corrugation height ratio is greater than 1, thereby increasing the hot air flow rate and ensuring the subsequent drying effect on the corrugations.

[0106] The beneficial effect brought about by the above implementation method is that the drying effect on the corrugated stack is achieved according to the combination of the first corrugation height and the third corrugation height.
