Description

Technical Field

[0001] The invention relates to the technical field of corrugated paperboard production, and more specifically, to a corrugated paperboard temperature control method and system. Background Art

[0002] In the field of corrugated cardboard production, the research on temperature control methods mainly involves the precise control technology of temperature during the production process, including temperature and humidity control of single-sided and double-sided units, real-time monitoring and adjustment of intelligent temperature control systems, etc. The significance of this research is to improve production efficiency, ensure the consistency of product quality, and achieve energy conservation and emission reduction, thereby promoting sustainable development while enhancing market competitiveness. Its importance is reflected in the ability to effectively avoid cardboard quality problems caused by temperature fluctuations, ensure efficient and stable production operation, and respond to social needs for environmental protection and energy conservation.

[0003] Temperature control methods in the field of corrugated cardboard production mainly rely on traditional manual control and simple automation systems. These methods have problems such as inaccurate temperature control, slow response speed, and high energy consumption, resulting in low production efficiency and unstable product quality. Specifically, traditional temperature control systems usually use mechanical temperature adjustment devices, such as thermocouples and bimetallic strips. Although these devices can achieve temperature monitoring and control to a certain extent, they have low accuracy and cannot adjust the temperature in real time, making it difficult to meet the needs of efficient production. In addition, these traditional methods lack comprehensive monitoring of temperature and humidity, which easily leads to temperature fluctuations during the production process, affecting the physical properties and packaging effects of the cardboard. The technical difficulties and key points lie in how to achieve high-precision temperature control and how to reduce energy consumption while ensuring production efficiency. Traditional temperature control systems often find it difficult to maintain stability under both high and low temperature conditions, which directly affects the quality of corrugated cardboard. For example, under high temperature conditions, if the temperature is not properly controlled, the corrugated cardboard is prone to softening, losing rigidity and tear strength; while under low temperature conditions, it may cause the paste liquid to solidify for a longer time, affecting production efficiency. In addition, traditional temperature control systems also have problems in energy efficiency, often causing energy waste and increasing production costs. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0075] In the field of corrugated cardboard production, the research on temperature control methods mainly involves the precise control technology of temperature during the production process, including temperature and humidity control of single-sided and double-sided units, real-time monitoring and adjustment of intelligent temperature control systems, etc. The significance of this research is to improve production efficiency, ensure the consistency of product quality, and achieve energy conservation and emission reduction, thereby promoting sustainable development while enhancing market competitiveness. Its importance is reflected in the ability to effectively avoid cardboard quality problems caused by temperature fluctuations, ensure efficient and stable production operation, and respond to social needs for environmental protection and energy conservation.

[0076] Temperature control methods in the field of corrugated cardboard production mainly rely on traditional manual control and simple automation systems.

Specifically, traditional temperature control systems usually use mechanical temperature adjustment devices, such as thermocouples and bimetallic strips.

The technical difficulties and key points lie in how to achieve high-precision temperature control and how to reduce energy consumption while ensuring production efficiency. Traditional temperature control systems often find it difficult to maintain stability under both high and low temperature conditions, which directly affects the quality of corrugated cardboard. For example, under high temperature conditions, if the temperature is not properly controlled, the corrugated cardboard is prone to softening, losing rigidity and tear strength; while under low temperature conditions, it may cause the paste liquid to solidify for a longer time, affecting production efficiency. In addition, traditional temperature control systems also have problems in energy efficiency, often causing energy waste and increasing production costs.

[0077] In the embodiment of the present invention, a corrugated board temperature control method and system are provided. The solution realizes precise control of temperature and pressure in the production process and improves production efficiency and product quality through sensor layout, single-facer temperature control system, hot plate temperature control system, condensate return system, corrugated line process speed-up system and display system.

[0078] According to a first aspect of an embodiment of the present invention, a method for controlling temperature of a corrugated paperboard is provided.

[0079] Figure 1 The present invention is a flow chart of a method for controlling temperature of corrugated paperboard according to an embodiment of the present invention.

[0080] In one or more embodiments, preferably, the temperature control method of corrugated board comprises:

[0081] S101. Install sensors in the corrugated board production line for online monitoring;

[0082] S102, performing temperature control of the single-sided machine online according to the production process and real-time temperature;

[0083] S103, precise control of temperature and pressure during steam delivery;

[0084] S104, obtaining condensed water for secondary utilization;

[0085] S105, automatically adjust the process speed of the corrugated line by using the flow channel arc preheating plate and the peak heating pre-gelatinizer;

[0086] S106. Display the operating status of the corrugated board production line online.

[0087] In the embodiments of the present invention, the existing temperature control method of corrugated paperboard mainly relies on traditional mechanical temperature adjustment devices, such as thermocouples and bimetallic strips. These traditional methods have problems such as inaccurate temperature control, slow response speed, high energy consumption, etc., resulting in low production efficiency and unstable product quality. In order to solve these problems, the present invention provides a temperature control method and system for corrugated paperboard.

[0088] Figure 2 The present invention is a flow chart of a method for controlling the temperature of corrugated board in accordance with an embodiment of the present invention, in which a sensor is arranged in a corrugated board production line for online monitoring.

[0089] like Figure 2 As shown, in one or more embodiments, preferably, the setting of sensors in the corrugated board production line for online monitoring specifically includes:

[0090] S201, installing an air inlet pipe, a drain pipe, a first steam trap group, a second steam trap group, a first pipeline pressure regulating assembly, and a second pipeline pressure regulating assembly on the single-sided unit and the double-sided unit respectively;

[0091] S202. Setting temperature detection elements and pressure detection elements in the corrugated board production line.

[0092] In an embodiment of the present invention, first, an air inlet pipe, a drain pipe, a first steam trap group, a second steam trap group, a first pipeline pressure regulating assembly and a second pipeline pressure regulating assembly are installed on the single-sided unit and the double-sided unit respectively. These components are used to adjust the flow and pressure of steam to ensure the stability of the production process. Then, a temperature detection element and a pressure detection element are set in the corrugated board production line. These elements can monitor the temperature and pressure changes in the production process in real time and transmit the data to the control system. In this way, production information can be obtained in real time, the production process can be determined according to the production information, and the temperature requirements of different periods in the production process can be extracted. Finally, an online matching gas temperature is formed according to the temperature requirement, and the steam control unit is adjusted according to the gas temperature to generate the original steam. In this way, accurate control of temperature and pressure in the production process can be achieved, and production efficiency and product quality can be improved.

[0093] Figure 3 The present invention is a flow chart of a method for controlling the temperature of a corrugated board in accordance with a production process and real-time temperature for online temperature control of a single-facer.

[0094] like Figure 3 As shown, in one or more embodiments, preferably, the temperature control of the single-sided machine is performed online according to the production process and the real-time temperature, specifically including:

[0095] S301, obtaining production information;

[0096] S302, determining the production process according to the production information, and extracting the temperature requirements at different time periods in the production process;

[0097] S303, forming an online matching gas temperature according to the temperature requirement;

[0098] S304, adjusting the steam control unit according to the gas temperature to generate raw steam.

[0099] In an embodiment of the present invention, first, the temperature and pressure data of the production process are monitored in real time by the temperature detection element and the pressure detection element installed on the single-sided unit. These data are transmitted to the control system for subsequent analysis and processing. The control system determines the current production process based on the acquired production information. Different production processes have different requirements for temperature, so it is necessary to extract the temperature requirements of different time periods from the production process. For example, in the forming process of corrugated cardboard, it may be necessary to preheat first, and then perform heating and cooling steps. Each step requires different temperature conditions to ensure product quality and production efficiency. According to the extracted temperature requirements of different time periods, the control system will form an online matching gas temperature. This matching gas temperature is calculated based on the temperature requirement at the current moment and the actual temperature difference. In this way, it can be ensured that the temperature requirements of the production process can be met in different time periods. Finally, according to the calculated matching gas temperature, the control system will adjust the working state of the steam control unit to generate original steam that meets the requirements. The steam control unit is responsible for controlling the flow and pressure of the steam. By adjusting its working parameters, accurate control of the original steam can be achieved. In this way, the temperature of the single-sided machine can be controlled online according to the production process and real-time temperature, thereby improving production efficiency and product quality.

[0100] Figure 4 The present invention is a flow chart of a method for controlling the temperature and pressure of corrugated paperboard during steam delivery in accordance with an embodiment of the present invention.

[0101] like Figure 4 As shown, in one or more embodiments, preferably, the precise control of temperature and pressure during steam delivery specifically includes:

[0102] S401, real-time monitoring of temperature and pressure during the wrapping process;

[0103] S402, adjusting the gas temperature using a first calculation formula according to the temperature change;

[0104] S403, adjusting the gas temperature using a second calculation formula according to the pressure change;

[0105] The first calculation formula is:

[0106] YT=k1×(PT-YP)×DT

[0107] Wherein, YT is the gas temperature, k1 is the first adjustment coefficient, PT is the average temperature, YP is the preset average temperature, and DT is the current gas temperature;

[0108] The second calculation formula is:

[0109] YT=k2×(PY-YY)×DT

[0110] Wherein, k2 is the second adjustment coefficient, PY is the average pressure, and YY is the preset average pressure.

[0111] In an embodiment of the present invention, the temperature and pressure conditions are monitored in real time: the temperature and pressure data in the production process are monitored in real time by the temperature detection element and the pressure detection element installed in the hot plate part. These data are transmitted to the control system for subsequent analysis and processing. The gas temperature is adjusted using a calculation formula: according to the monitored temperature and pressure changes, the control system uses the first calculation formula and the second calculation formula to adjust the gas temperature. The first calculation formula is: YT = k1 × (PT-YP) × DT, where YT is the gas temperature, k1 is the first adjustment coefficient, PT is the average temperature, YP is the preset average temperature, and DT is the current gas temperature. The second calculation formula is: YT = k2 × (PY-YY) × DT, where k2 is the second adjustment coefficient, PY is the average pressure, and YY is the preset average pressure. Through these two formulas, the appropriate gas temperature can be calculated according to the changes in temperature and pressure. Achieve precise control: According to the calculated gas temperature, the control system adjusts the working state of the steam control unit to generate raw steam that meets the requirements. The steam control unit is responsible for controlling the flow and pressure of steam. By adjusting its working parameters, it can achieve precise control of the original steam. In this way, the temperature of the hot plate can be controlled online according to the temperature and pressure changes during the steam delivery process, thereby improving production efficiency and product quality.

[0112] Figure 5 The present invention is a flow chart of obtaining condensed water for secondary utilization in a corrugated cardboard temperature control method according to an embodiment of the present invention.

[0113] like Figure 5 As shown, in one or more embodiments, preferably, the obtaining of condensed water for secondary utilization specifically includes:

[0114] S501, reusing the steam obtained by steam-water separation in a low temperature zone;

[0115] S502, automatically replenishing original steam in case of insufficient secondary steam, wherein the original steam is the steam initially formed;

[0116] S503, discharge the water flow formed by the steam-water separation to a recovery machine;

[0117] S504, judging whether the third calculation formula is satisfied, and replenishing the condensed water from the recovery machine to the boiler for secondary use; otherwise, the condensed water is sent to the boiler soft water tank for storage;

[0118] The third calculation formula is:

[0119] YSY>(HSS+DSL)÷DWG

[0120] Among them, YSY is the preset boiler water level constraint, HSS is the condensate of the recovery machine, DSL is the current boiler water volume, and DWG is the boiler water storage volume per unit height.

[0121] In an embodiment of the present invention, the generated steam is separated from water: first, the generated steam is separated from water by a steam-water separator installed on the production line. The water in the steam will be separated to form condensed water. The steam obtained by steam-water separation is reused in the low-temperature zone: the separated steam can be used again in the low-temperature area of ​​the production line. This helps to improve energy utilization and reduce energy waste. Automatically replenish the original steam: if the steam for secondary utilization is insufficient, the system will automatically replenish the original steam. The original steam refers to the steam initially formed, and its temperature and pressure meet the requirements of the production process. The water flow formed by the steam-water separation is discharged to the recovery machine: the condensed water formed after the steam-water separation will be discharged to the recovery machine. The recovery machine is responsible for collecting and storing these condensed water for subsequent processing and utilization. It is judged that the third calculation formula is satisfied and the condensed water of the recovery machine is replenished to the boiler for secondary utilization: according to the third calculation formula: YSY>(HSS+DSL)÷DWG, where YSY is the preset boiler water level constraint, HSS is the condensed water of the recovery machine, DSL is the current boiler water volume, and DWG is the boiler water volume per unit height. If this condition is met, it means that the condensate of the recovery machine is sufficient and can be added to the boiler for secondary use. This can further improve energy utilization and reduce energy waste. Otherwise, it is sent to the boiler soft water tank for storage: If the judgment result does not meet the conditions of the third calculation formula, it means that the condensate of the recovery machine is insufficient and cannot be directly added to the boiler for secondary use. At this time, the condensate needs to be sent to the boiler soft water tank for storage for subsequent use.

[0122] Figure 6 The present invention is a flow chart of a method for controlling the temperature of corrugated paperboard in one embodiment of the present invention, which automatically adjusts the process speed of a corrugated paperboard line by using a flow channel arc preheating plate and a flute peak heating pregelatinizer.

[0123] like Figure 6 As shown, in one or more embodiments, preferably, the process speed of the corrugator line is automatically adjusted by using the flow channel arc preheating plate and the peak heating pregelatinizer, specifically including:

[0124] S601, setting a flow channel arc preheating plate for the preheating equipment on the corrugated paperboard production line, so as to preheat the single-sided corrugated paper quickly and evenly;

[0125] S602, setting a flute heating pre-gelatinizer to heat the flute of the corrugated board to a preset temperature;

[0126] S603: When it is determined that the paper surface temperature reaches a preset range, the traveling speed of the corrugated board production line is increased.

[0127] In an embodiment of the present invention, the process speed of the corrugated line is automatically adjusted by using a flow channel arc preheating plate and a flute peak heating pregelatinizer. The flow channel arc preheating plate is set as a preheating device on the corrugated board production line: First, the flow channel arc preheating plate is installed on the production line. This preheating plate has a special arc design, which can make the single-face corrugated paper receive uniform heat distribution when passing through, thereby achieving a fast and uniform preheating effect. In this way, the molding quality of the corrugated board can be improved and the defects caused by uneven temperature can be reduced. The flute peak heating pregelatinizer is set to heat the flute peak of the corrugated board: Next, the flute peak heating pregelatinizer is installed. This device is specifically used to heat the flute peak part of the corrugated board to reach a preset temperature. By accurately heating the flute peak, the strength and stability of the corrugated board can be enhanced, and the compressive resistance of the product can be improved. When it is judged that the paper surface temperature reaches a preset range, the travel speed of the corrugated board production line is increased: when the paper surface temperature sensor detects that the paper surface temperature reaches a preset range, the control system will automatically increase the travel speed of the corrugated board production line. This means that the production process can achieve higher production efficiency while ensuring product quality. By real-time monitoring and automatic adjustment of travel speed, product defects and energy waste caused by too fast or too slow speed can be avoided.

[0128] Figure 7 It is a flow chart for online display of the operating status of a corrugated board production line in a corrugated board temperature control method according to an embodiment of the present invention.

[0129] like Figure 7 As shown, in one or more embodiments, preferably, the online display of the operating status of the corrugated board production line specifically includes:

[0130] S701, online display of the internal temperature of the corrugated board, the temperature of the hot plate, the temperature of the corrugated board machine and the ambient temperature;

[0131] S702, updating the current temperature setting value online;

[0132] S703, online display of the remaining meters of paper in the hot plate and the gluing machine and the materials under the current production plan.

[0133] In an embodiment of the present invention, the paper temperature, hot plate temperature, tile machine temperature and ambient temperature of the corrugated board are displayed online: First, the temperature sensors installed on the production line monitor and collect key parameters such as the paper temperature, hot plate temperature, tile machine temperature and ambient temperature of the corrugated board in real time. These data are transmitted to the central control system and intuitively displayed to the user in the form of charts or numbers through the user interface. In this way, the operator can clearly understand the current status of the production line and promptly discover and solve potential problems. Online update of the temperature setting value at the current moment: In addition to real-time display of temperature data, the system also allows the operator to update the temperature setting value at the current moment online. This means that during the production process, if a temperature parameter is found to be unsatisfactory, the operator can immediately adjust it through the user interface without stopping the machine or waiting for the technician to arrive. This flexible temperature control method helps to improve production efficiency and product quality. Online display of the remaining meters of paper on the hot plate and the gluing machine and the material under the current production plan: In addition, the system also displays the remaining meters of paper on the hot plate and the gluing machine and the material information under the current production plan online. These data are crucial for production management and scheduling. By knowing the quantity and type of remaining paper in real time, managers can adjust production plans in time to avoid production interruptions due to material shortages. At the same time, understanding the material information under the current production plan also helps to ensure the consistency and traceability of product quality. In summary, Example 1 provides operators and managers with a comprehensive and real-time production monitoring method by displaying the operating status of the corrugated board production line online, including key parameters such as temperature data, the quantity of remaining paper, and material information. This helps to improve production efficiency, ensure product quality, and optimize production management processes.
