Description

Technical Field

[0001] The present invention belongs to the field of humidity monitoring devices, and specifically relates to a corrugated cardboard humidity detection system. Background Art

[0002] As an important part of packaging materials, the quality stability of corrugated cardboard is crucial for the transportation and storage safety of products. However, the performance of corrugated cardboard is extremely susceptible to the influence of moisture content. Whether the moisture content is too high or too low, it will cause various faults during the production and use of corrugated cardboard, such as collapsed flutes, delamination, cracks, uneven corrugation formation, etc. Therefore, accurate detection and control of the moisture content of corrugated cardboard have become a key link to ensure the quality of corrugated cardboard.

[0003] In the prior art, a hygrometer or sensor is mainly used for single-point measurement, which often fails to comprehensively reflect the overall humidity situation of corrugated cardboard. Due to the fact that corrugated cardboard may be affected by various factors during the production process, resulting in uneven humidity distribution, it is difficult to accurately capture this change through single-point measurement.

[0004] Therefore, there is an urgent need for a detection system that can synchronously detect multiple positions of corrugated cardboard and comprehensively reflect the humidity distribution of corrugated cardboard. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a corrugated cardboard humidity detection system, which can achieve accurate detection and control of the humidity of corrugated cardboard, and improve production efficiency and product quality.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows: A corrugated cardboard humidity detection system includes a detection box; a balance module, a detection module, a humidity adjustment module, and a control module are arranged in the detection box; the balance module is used to eliminate the interference of the traction force at both ends of the corrugated base paper on the detection area on the corrugated base paper during detection; the detection module includes a first carrier and a second carrier; the first carrier is located above the second carrier; an air-powered component for blowing air towards the bottom of the corrugated base paper is arranged on the first carrier; a ranging component is arranged on the second carrier, and the ranging component is used to collect the displacement generated by the corrugated base paper when the air flow blows towards the corrugated base paper; the humidity adjustment module is used to adjust the humidity of the corrugated base paper in the detection box; the control module is used to judge the humidity situation of the corrugated base paper based on the displacement situation collected by the ranging component and control the operation of the humidity adjustment module.

[0007] Adopting the above solution has the following beneficial effects: 1. In this solution, the corrugated base paper to be detected is fed into the detection box. The traction force at both ends of the corrugated base paper is eliminated by the balance module. The pneumatic component blows air to one side of the corrugated base paper, and then the displacement generated by the corrugated base paper is detected by the ranging component. The control module judges the humidity condition of the current position (the position being blown) of the corrugated base paper based on the displacement situation, and controls the humidity adjustment module to regulate the humidity of the corrugated base paper.

[0008] In this solution, the pneumatic component blows air to one side of the corrugated base paper, and the displacement generated is detected by the ranging component. Compared with the traditional single-point measurement, this measurement method can more accurately reflect the humidity change of the corrugated cardboard. Even the slightest change in displacement can be accurately captured, thus improving the accuracy and reliability of the detection.

[0009] 2. In this solution, the control module can judge the humidity condition of the corrugated base paper in real time according to the displacement data collected by the ranging component, and immediately start the humidity adjustment module for regulation. This dynamic regulation mechanism can ensure that the corrugated cardboard maintains the best humidity state during production and use, and avoid quality problems such as reverse corrugation, delamination, cracks, and uneven corrugation formation.

[0010] Furthermore, several pneumatic components, several ranging components, and several humidity adjustment modules are arranged in the detection box; the pneumatic components, ranging components, and humidity adjustment modules are arranged in a matching manner along the moving direction of the corrugated base paper.

[0011] Beneficial effects: By arranging multiple pneumatic components and ranging components along the moving direction of the corrugated base paper in the detection box, the present invention realizes the synchronous detection of multiple positions of the corrugated cardboard. This multi-point synchronous detection method can more comprehensively and accurately reflect the humidity distribution of the corrugated cardboard compared with single-point or few-point detection. It avoids the one-sidedness that may be brought by single-point detection and improves the accuracy and reliability of the detection results.

[0012] The pneumatic components, ranging components, and humidity adjustment modules arranged along the moving direction of the corrugated base paper form a continuous monitoring and regulation system. When the humidity of the corrugated base paper in the detection area needs to be regulated, the humidity adjustment module will immediately intervene. After the regulation is completed, the subsequent pneumatic components and ranging components will re-inspect this area to ensure that the humidity regulation result meets the standard. This continuous monitoring and regulation method ensures the humidity stability of the corrugated cardboard during the production process, thus improving the product quality.

[0013] Further, the balancing module includes a first guide wheel, a pair of rollers, a second guide wheel, an adjusting rod, and a guiding column; the first guide wheel, the pair of rollers, the second guide wheel, the adjusting rod, and the guiding column are symmetrically distributed in sequence within the detection box; the first guide wheels are each rotatably connected to the side wall of the detection box; the pair of rollers is used to provide the traction force for the corrugated base paper to move within the detection box; the second guide wheels are each rotatably connected to the side wall of the detection box; the adjusting rod is used to cause the corrugated base paper to form troughs; the guiding column is used to cause the corrugated base paper to form crests.

[0014] Beneficial effects: Through the ingenious arrangement and combination of the first guide wheel, the second guide wheel, the adjusting rod, and the guiding column, the balancing module of the present invention successfully places the middle region of the corrugated base paper (i.e., the region between the guiding columns) in a natural relaxation state. In this state, the traction force can only act on the corrugated base paper in the horizontal direction, and is perpendicular to the direction of the gravity of the corrugated base paper. This design effectively eliminates the potential influence of the traction force on the humidity detection result of the corrugated base paper, and improves the accuracy and reliability of the detection.

[0015] The combined use of the adjusting rod and the guiding column not only causes the corrugated base paper to form troughs and crests during the detection process, but also precisely controls the shape of the corrugations. This precise control helps to maintain the consistency and stability of the corrugated base paper during the detection process, thereby further improving the accuracy and reliability of the humidity detection.

[0016] Further, corrugation shape detection components are also symmetrically arranged within the detection box; the corrugation shape detection components include fixed columns, and buffer grooves are provided within the fixed columns; a second spring is provided within the buffer grooves; a sliding rod is provided at the bottom of the second spring; the sliding rod is slidably engaged with the buffer groove; a ball head is provided at the bottom of the sliding rod; a pressure sensor is provided at the bottom of the ball head; the pressure sensor is electrically connected to the control module; the control module is further used to control the operation of the pair of rollers based on the information collected by the pressure sensor.

[0017] Beneficial effects: By symmetrically arranging the corrugation shape detection components within the detection box, the present invention can monitor the pressure conditions at both ends of the middle position of the corrugated base paper in real time. This design helps to determine whether the corrugated base paper is in a relaxed state, thereby ensuring that the corrugated base paper will not generate errors due to being taut during the humidity detection process. If the shape of the corrugated base paper is relatively taut, the pressure sensor will be able to quickly collect the pressure change and feedback it to the control module.

[0018] Based on the information collected by the pressure sensor, the control module can intelligently adjust the rotation speed of the corresponding pair of rollers. When the corrugated base paper is in a taut state, the control module will reduce the rotation speed of the pair of rollers, thereby reducing the traction force and avoiding damage to the middle position of the corrugated base paper due to excessive stretching. This intelligent adjustment mechanism ensures the stability and safety of the corrugated base paper during the detection process.

[0019] The buffer groove, second spring, slide bar and ball head design in the corrugated form detection component form an effective buffer system. When the corrugated base paper is too tight, it will squeeze the ball head, thereby pushing the slide bar along the buffer groove. In this process, the second spring plays a buffering role, which can relieve the restraint of the ball head on the corrugated base paper, preventing the tension from continuing to develop and causing damage to the corrugated base paper. This design not only protects the corrugated base paper, but also improves the reliability and durability of the detection system.

[0020] Furthermore, the pneumatic component includes a fan and a gun nozzle; a plurality of ventilation ducts are arranged on the top of the second carrier; the fan is located in the ventilation duct; and the top of the ventilation duct is connected to the gun nozzle.

[0021] Beneficial effect: The pneumatic assembly consists of a fan and a gun nozzle, which are connected through a ventilation duct on the top of the second carrier. When the corrugated paper passes through the second carrier, the fan continues to run, blowing the outside air to the bottom of the corrugated paper through the ventilation duct and the gun nozzle.

[0022] Furthermore, the ranging component includes a contact block; the mass of the contact block is lower than a preset value; a plurality of detection cavities are arranged at the bottom of the first carrier; the contact block and the detection cavity are slidably matched; a capacitor plate is arranged at the top of the contact block and the top of the detection cavity; and the capacitor plate is electrically connected to the control module.

[0023] Beneficial effects: The distance measuring component mainly includes a contact block, a detection cavity and a capacitor plate. The mass of the contact block is carefully designed to be lower than the preset value to ensure that it can sensitively respond to external forces (such as the impact force when the corrugated base paper is blown up by the pneumatic component). Several detection cavities are set at the bottom of the first carrier, and the contact block slides with these detection cavities to allow the contact block to move up and down when subjected to external forces. Capacitor plates are installed on the top of the contact block and the top of the detection cavity. These capacitor plates are electrically connected to the control module for real-time monitoring of the position changes of the contact block.

[0024] When the corrugated paper is blown upward by the wind generated by the pneumatic component, it will come into contact with the contact block and push the contact block to slide upward. Since the weight of the corrugated paper will be different under different humidity conditions, the distance the contact block slides upward can reflect the humidity of the corrugated paper. The higher the humidity, the lower the weight of the corrugated paper, the smaller the pushing effect on the contact block, and the smaller the distance the contact block moves upward; conversely, the lower the humidity, the greater the distance the contact block moves upward. This design enables the system to monitor the humidity changes of the corrugated paper in real time, providing strong support for quality control in the production process.

[0025] By using the capacitor plate to monitor the position change of the contact block, the system can achieve high-precision displacement measurement. The electrical connection between the capacitor plate and the control module ensures real-time transmission and processing of data, thereby improving the sensitivity and accuracy of detection.

[0026] Furthermore, the humidity adjustment component includes an electric heating coil and a nozzle; the electric heating coil is located inside the ventilation duct; the electric heating coil is electrically connected to the control module; the nozzle is used to spray water vapor onto the corrugated base paper; the nozzle is electrically connected to the control module.

[0027] Beneficial effects: The humidity adjustment component mainly includes an electric heating coil and a nozzle. The electric heating coil is ingeniously installed inside the ventilation duct and is electrically connected to the control module to receive control signals and perform heating operations. The nozzle is responsible for spraying water vapor onto the corrugated base paper and is also electrically connected to the control module to ensure water spraying operations as needed.

[0028] The humidity adjustment component can perform intelligent adjustment according to the real-time humidity condition of the corrugated base paper. When the humidity is high, the control module will activate the electric heating coil, heat the air inside the ventilation duct, and use the fan to blow the hot air towards the corrugated base paper to accelerate the evaporation of the internal moisture, thereby reducing the humidity. On the contrary, when the humidity is low, the control module will control the nozzle to spray water vapor onto the top of the corrugated base paper to increase its humidity. This intelligent adjustment mechanism ensures that the corrugated base paper always maintains an appropriate humidity level during the production process, which helps to improve the overall quality of the product.

[0029] Furthermore, a number of smooth support blocks are also provided on the top of the second carrier; the smooth support blocks are used to support the movement of the corrugated base paper.

[0030] Beneficial effects: The smooth support blocks are made of wear-resistant and smooth materials to reduce the friction with the corrugated base paper. This design helps to reduce the wear and damage of the corrugated base paper during movement and extend its service life. At the same time, reducing friction can also reduce the operating noise of the detection system and improve the comfort of the working environment.

[0031] Furthermore, it also includes a tension adjustment component; the tension adjustment component includes a limit block and a driving member; the limit block is provided at the top of the adjustment rod; a driving wheel is provided at the top of the adjustment rod; the driving wheel is rotatably connected to the inner wall of the detection box; the driving member is used to drive the driving wheel to rotate; the driving member is electrically connected to the control module; a chute is provided inside the adjustment rod; a first spring is provided inside the chute; the bottom of the first spring is provided with a connecting rod; the connecting rod is slidably engaged with the chute; the bottom of the connecting rod is rotatably connected to a driven wheel.

[0032] Beneficial effects: The deflection angle of the adjustment rod is intelligently adjusted through the control module, thereby precisely controlling the tension degree of the corrugated base paper. This intelligent adjustment mechanism helps to ensure that the corrugated base paper maintains an appropriate tension state during the production process, avoiding production problems such as paper jams and wrinkles caused by improper tension, and thus improving the overall quality of the product.

[0033] Further, it further includes a monitoring module; the monitoring module is used to monitor the running speed of the counter-rollers in real time; the control module is further used to judge the length of the corrugated base paper in the detection box based on the data collected by the monitoring module, and adjust the running of the counter-rollers and the driving member.

[0034] Beneficial effects: By monitoring the running speed of the counter-rollers in real time and accurately judging the length of the corrugated base paper, the control module can ensure that the corrugated base paper is conveyed and processed at the correct speed and length (the length side corresponds to the tightness of the corrugated base paper in the detection box) during the humidity detection process.

[0045] The following is a further detailed description through specific embodiments: Embodiment 1 is basically as shown in the attached drawings: A corrugated cardboard humidity detection system mainly includes a detection box 1. In this embodiment, the detection box 1 is installed on the production line of corrugated base paper 3. In this embodiment, the corrugated base paper 3 is in a roll shape. Figures 1-6

[0046] A balance module, a detection module, a humidity adjustment module, and a control module are arranged in the detection box 1.

[0047] The balance module is used to eliminate the interference of the traction forces at both ends of the corrugated base paper 3 during detection on the detection area on the corrugated base paper 3.

[0048] Specifically, as shown in the attached drawings, the balance module includes a first guide wheel 4, a pair of rollers 5, a second guide wheel 6, an adjusting rod 7, and a guide post 8; the first guide wheel 4, the pair of rollers 5, the second guide wheel 6, the adjusting rod 7, and the guide post 8 are symmetrically distributed in sequence in the detection box 1, specifically symmetrically arranged with the detection module as the center; the first guide wheels 4 are rotatably connected to the side walls of the detection box 1. In this embodiment, the first guide wheels 4 are located at the uppermost position; the pair of rollers 5 is used to provide the traction force for the movement of the corrugated base paper 3 in the detection box 1. The pair of rollers 5 is located below the first guide wheels 4. In this embodiment, the traction force generated by the pair of rollers 5 is vertically downward; the second guide wheels 6 are rotatably connected to the side walls of the detection box 1. In this embodiment, the second guide wheels 6 are mainly used to guide the corrugated base paper 3 towards the detection module; the adjusting rod 7 is used to make the corrugated base paper 3 generate wave troughs. Specifically, as shown in the attached drawings, the adjusting rod 7 is located above the corrugated base paper 3, and a tension adjustment assembly is also arranged on the adjusting rod 7; as shown in the attached drawings Figure 3 Figure 3 Figure 5 ​​As shown, the tension adjustment assembly includes a limit block 701 and a driving member; the limit block 701 is provided at the top of the adjusting rod 7. In this embodiment, the limit block 701 is in an inverted "V" shape and is fixedly connected to the inner wall of the detection box 1 by welding; a driving wheel 702 is fixedly connected to the top of the adjusting rod 7; the driving wheel 702 is rotatably connected to the inner wall of the detection box 1; the driving member is used to drive the driving wheel 702 to rotate. In this embodiment, the driving member is a servo motor, and the output shaft of the servo motor is fixedly connected to the driving wheel 702 axially by welding; the driving member is electrically connected to the control module; a chute 705 is opened inside the bottom of the adjusting rod 7; a first spring 706 is arranged in the chute 705, and the top of the first spring 706 is fixedly connected to the top wall of the chute 705 by welding; a connecting rod 704 is arranged at the bottom of the first spring 706, and the connecting rod 704 is fixedly connected to the first spring 706 by welding; the connecting rod 704 is slidably matched with the chute 705; a driven wheel 703 is rotatably connected to the bottom of the connecting rod 704. As shown in the appendix Figure 3 and the appendix Figure 4 As shown, the guide post 8 is used to generate wave crests on the corrugated base paper 3. In this embodiment, the guide post 8 is located at the bottom of the corrugated base paper 3, and the bottom of the guide post 8 is fixedly connected to the inner wall of the detection box 1 by welding.

[0049] The detection module includes a first carrier 10 and a second carrier 11; a plurality of smooth support blocks 20 are fixedly connected to the top of the second carrier 11; the smooth support blocks 20 are used to support the movement of the corrugated base paper 3, and the smooth support blocks 20 are arranged along the moving direction of the corrugated base paper 3. As shown in the appendix Figure 3 and the appendix Figure 4 As shown, the first carrier 10 is located above the second carrier 11; a pneumatic assembly for blowing air to the bottom of the corrugated base paper 3 is arranged on the first carrier 10. Specifically, 4 groups of pneumatic assemblies are arranged in this embodiment; the pneumatic assembly includes a fan 18 and a nozzle 17; a plurality of ventilation ducts 16 are opened at the top of the second carrier 11. In this embodiment, both ends of the ventilation duct 16 communicate with the outside from the top and side of the second carrier 11 respectively; the fans 18 are respectively installed in the ventilation ducts 16; the top of the ventilation duct 16 is communicated with the nozzle 17, and the nozzle 17 is fixed to the second carrier 11 by screws.

[0050] A ranging assembly is arranged on the second carrier 11. The ranging assembly is used to collect the displacement (mainly the displacement in the gravity direction) generated by the corrugated base paper 3 when the air flow blows on the corrugated base paper 3. In this embodiment, 4 groups of ranging assemblies are arranged in total. Specifically, the ranging assembly includes a touch block 15; the mass of the touch block 15 is lower than a preset value (that is, the touch block 15 is lighter). In this embodiment, the purpose of setting the mass of the touch block 15 lower than the preset value is mainly to be able to quickly respond to the force exerted on the touch block 15 when the corrugated base paper 3 moves upward; a plurality of detection cavities 13 are opened at the bottom of the first carrier 10; the touch blocks 15 are all slidably matched with the detection cavities 13; As shown in the appendix Figure 4As shown, a capacitor plate 14 is adhesively fixed to the top of the contact block 15 and the top of the detection chamber 13; the capacitor plate 14 is electrically connected to the control module.

[0051] The humidity adjustment module is used to adjust the humidity of the corrugated base paper 3 in the detection box 1. Specifically, the humidity adjustment assembly includes an electric heating coil 19 and a spray head 12; the electric heating coil 19 is welded and fixed in the ventilation duct 16; the electric heating coil 19 is electrically connected to the control module; the spray head 12 is used to spray water vapor onto the corrugated base paper 3. In this embodiment, the spray head 12 is fixed to the bottom of the first carrier 10 by screws; the spray head 12 is electrically connected to the control module.

[0052] In this embodiment, the pneumatic assembly, the ranging assembly, and the humidity adjustment module are arranged in a supporting manner along the moving direction of the corrugated base paper 3. That is, a single pneumatic assembly, ranging assembly, and humidity adjustment module form a unit, and each unit has the function of detecting and adjusting humidity. At the same time, the subsequent unit can re-inspect the corrugated base paper 3 after the previous unit has detected or adjusted the humidity.

[0053] The control module is used to judge the humidity condition of the corrugated base paper 3 based on the displacement situation collected by the ranging assembly, that is, the distance between the capacitor plates 14, and control the operation of the humidity adjustment module.

[0054] The specific implementation process is as follows: The corrugated base paper 3 is drawn through the inside of the detection box 1 by the driving of the counter-rollers 5. In this embodiment, openings 2 are provided on both sides of the detection box 1, and the corrugated paper box extends into the inside of the detection box 1 through the openings 2. By rotating the counter-rollers 5, the corrugated base paper 3 moves on the first guide wheel 4, the second guide wheel 6, the guide post 8, the fixed post 9, and the smooth support block 20. The left counter-roller 5 conveys the corrugated base paper 3 into the detection box 1, and the right counter-roller 5 conveys the corrugated base paper 3 out of the detection box 1. Through the ingenious arrangement and combination of the first guide wheel 4, the second guide wheel 6, the adjusting rod 7, and the guide post 8, the middle area of the corrugated base paper 3 (that is, the area between the guide posts 8, and this area is the detection area) is placed in a natural relaxation state.

[0055] When detecting the humidity of the corrugated base paper 3, the fan 18 is started. The fan 18 will continuously generate a fixed wind force. When the corrugated base paper 3 passes through the nozzle 17 between the smooth support blocks 20, the wind force will overcome the gravity of the corrugated base paper 3 at this position (specifically, the position directly opposite the nozzle 17), and lift the corrugated base paper 3 upward. Since the bottom of the contact block 15 contacts the top of the corrugated base paper 3, when the corrugated base paper 3 arches upward, it will drive the contact block 15 to move upward. The contact block 15 slides within the detection cavity 13, changing the distance between the capacitor plates 14. The control module calculates the distance between the capacitor plates 14 by obtaining the capacitance change of the capacitor plates 14. If the distance exceeds the preset range, it indicates that the corrugated base paper 3 is lighter and has a lower humidity. The control module then controls the nozzle 12 to operate, and the nozzle 12 sprays water vapor onto the corrugated base paper 3 to increase the humidity of the corrugated base paper 3. When the distance is lower than the preset range, it indicates that the corrugated base paper 3 is heavier and has a higher humidity. The control module then controls the heating coil 19 of the next unit (i.e., the heating coil 19 behind in the moving direction of the corrugated base paper 3) to operate, so that the air blown out from the next ventilation duct 16 is hot air, accelerating the evaporation of the moisture inside the corrugated base paper 3, thereby reducing the humidity. When the area with adjusted humidity passes through the next nozzle 17, the above process is repeated to re-inspect this area until the humidity of the corrugated base paper 3 meets the standard (i.e., the distance is within the preset range).

[0056] The difference between Embodiment 2 and the above Embodiment 1 is only that a corrugation shape detection component is symmetrically arranged in the detection box 1; the corrugation shape detection component includes a fixed column 9, and a buffer groove 901 is formed in the fixed column 9; a second spring 902 is arranged in the buffer groove 901, and the top of the second spring 902 is welded and fixed to the top inner wall of the buffer groove 901; a sliding rod 903 is welded and fixed to the bottom of the second spring 902; the sliding rod 903 is slidably matched with the buffer groove 901; a ball head 904 is welded and fixed to the bottom of the sliding rod 903 to facilitate the corrugated base paper 3 to slide along the curved surface of the ball head 904; a pressure sensor 905 is embedded at the bottom of the ball head 904; the pressure sensor 905 is electrically connected to the control module; the control module is also used to control the operation of the counter-roller 5 based on the information collected by the pressure sensor 905.

[0057] Specific implementation process: When the pressure sensor 905 detects a pressure change, it indicates that the corrugated base paper 3 is in close contact with the ball head 904, and at this time, the corrugated base paper 3 is in a taut state. If the left pressure sensor 905 detects a pressure change, the control module controls the left counter-roller 5 to increase the rotation speed. If the right pressure sensor 905 detects a pressure change, the control module controls the right counter-roller 5 to decrease the rotation speed.

[0058] Embodiment 3 is different from the above-mentioned Embodiment 2 only in that it further includes a monitoring module. The monitoring module is used to monitor the running speed of the counter rolls 5 in real time. In this embodiment, the monitoring module is a rotational speed sensor, which is installed at the output end of each counter roll 5; the control module is further used to judge the length of the corrugated base paper 3 in the detection box 1 based on the data collected by the monitoring module, and adjust the running of the counter rolls 5 and the driving member.

[0059] Specific implementation process: For example, if the left counter roll 5 inputs the corrugated base paper 3 at a speed of 0.1 m / s and the right counter roll 5 outputs the corrugated base paper 3 at a speed of 0.1 m / s, then the length of the corrugated base paper 3 in the detection box 1 will remain unchanged. If the left counter roll 5 has a power fluctuation due to various factors and inputs the corrugated base paper 3 at a speed of 0.2 m / s at this time, then the length of the corrugated base paper 3 in the detection box 1 will gradually increase and accumulate in the detection box 1. At this time, the control module will increase the rotational speed of the right counter roll 5 or decrease the rotational speed of the left counter roll 5, or the control module controls the driving member to run. The driving member drives the driving wheel 702 to rotate, and then the adjusting rod 7 deflects, so as to adjust the height of the wave trough. The higher the wave trough height, the flatter the corrugated base paper 3 between the second guide wheel 6 and the guide post 8, that is, the shorter the length of the corrugated base paper 3 passing between the second guide wheel 6 and the guide post 8. The higher the wave trough height, the more tortuous the corrugated base paper 3 between the second guide wheel 6 and the guide post 8, and the longer its unfolded length. In this embodiment, when the adjusting rod 7 deflects to the right, the corrugated base paper 3 is flatter; when it deflects to the left, the corrugated base paper 3 is more tortuous; therefore, the control module controls the adjusting rod 7 to deflect to the left, so as to increase the length of the corrugated base paper 3 between the second guide wheel 6 and the guide post 8, thereby alleviating the accumulation of the corrugated base paper 3.
