Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard processing and production technology, specifically to a reinforced corrugated cardboard processing device and processing method. Background Technology

[0002] Corrugated cardboard, as a lightweight, high-strength, and low-cost packaging material, is widely used in various industries such as electronics, home appliances, food, and logistics, and is an indispensable component of modern packaging systems. As market demands for the load-bearing capacity and impact resistance of packaging materials continue to increase, the industry often increases the thickness of corrugated cardboard by laminating it with a film. While this method can increase thickness to some extent, large-area lamination significantly increases the overall weight.

[0003] Meanwhile, the additional lamination process increases raw material and processing costs, and the extra lamination layer is difficult to separate after disposal, also increasing the difficulty of recycling. Therefore, we designed a reinforced corrugated cardboard processing device and method that, while ensuring increased strength, does not excessively increase the weight of the cardboard and reduces the difficulty of recycling, better meeting the market demand for high-strength corrugated cardboard. Summary of the Invention

[0004] The purpose of this invention is to provide a reinforced corrugated cardboard processing apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reinforced corrugated cardboard processing apparatus, comprising: Support frame; A transmission mechanism, mounted on the support frame, is used to guide the corrugated paper out of the paper and control the tension of the corrugated paper. The coating mechanism is mounted on the support frame and connected to the transmission mechanism. The coating mechanism is driven by the transmission mechanism and is used to load adhesive and coat it onto the corrugated paper. The coating mechanism is also equipped with a stirring component, which is used to stir the adhesive loaded in the coating mechanism to ensure that the viscosity of the adhesive remains consistent.

[0006] In some embodiments, the transmission mechanism includes at least three rotating rollers mounted on the support frame and driven by a motor mounted on the support frame. All of the rotating rollers are equipped with gear sets, which transmit the rotational force of the rotating rollers to the coating mechanism.

[0007] In some embodiments, the application mechanism includes a storage tank for storing adhesive, with a drive rod connected to the gear set on the outside of the storage tank, and the drive rod connected to the stirring element.

[0008] In some embodiments, the stirring element includes a central rod disposed on the transmission rod, a support rod disposed on the central rod, an outer ring stirring blade disposed on the support rod, an inner ring stirring blade disposed on the central rod, and a central stirring blade disposed in the middle of the central rod.

[0009] In some embodiments, the outer ring stirring blades and the inner ring stirring blades are two sets, arranged in a mirror image opposite each other on the central rod; The outer ring stirring blades and the inner ring stirring blades are in opposite stirring directions based on the adhesive; The two outer ring stirring blades are used to stir the adhesive toward the center of the central rod; The two inner ring stirring blades are used to stir the adhesive towards both ends of the central rod; The central stirring blade is used to stir the adhesive in the middle of the central rod.

[0010] In some embodiments, the application mechanism further includes an applicator disposed on one side of the storage tank, the applicator having an application roller, and the two ends of the application roller having first transmission components; A second transmission component is provided at the same longitudinal position as the central rod and the first transmission component; The second transmission component and the first transmission component are fitted with toothed belts.

[0011] In some embodiments, a synchronization guide is provided at the center of the central rod, the synchronization guide being used to guide the direction of the reinforcing strips included in the corrugated paper; The synchronous guide is provided with limiting plates at both ends, which are used to limit the reinforcing strip.

[0012] In some embodiments, the inner wall of the storage tank is hollow, and a temperature regulating plate is provided on its inner side; The storage tank is also equipped with a liquid level detector for detecting the liquid level of the adhesive stored in the storage tank, and the liquid level detector is connected to a replenishment pipe; A temperature detector is installed at the bottom of the storage box; A viscosity detector is provided at the end of the support rod; The number of the application mechanism is two.

[0013] A method for processing reinforced corrugated cardboard includes the following steps: The initial end of the corrugated paper is connected to the transmission mechanism, the reinforcing tape is wound in the coating mechanism, and the parameters of the corrugated paperboard and the constant temperature of the adhesive are input. The processing device system calls the built-in mathematical model of adhesive consumption to calculate the total amount of adhesive required for this operation, and controls the external feed pump of the feed pipe to add adhesive to the storage tank. The total amount of adhesive added matches the total amount of adhesive calculated by the digital model. Start the reinforced corrugated cardboard processing device. The motor drives the transmission mechanism to rotate, and the gear set drives the coating mechanism at the same speed to stir the built-in adhesive and drive the reinforcing belt. The coating mechanism includes an applicator located on one side of the storage box for applying adhesive to the inside of the corrugated paper, fusing the reinforcing strip, and inspecting and drying it.

[0014] In some embodiments, the gear set drives the application mechanism at the same speed, causing the outer and inner ring stirring blades on the central rod to rotate, stirring the adhesive toward the synchronous guide; The temperature detector detects temperature changes in the adhesive caused by environmental factors in real time. When the temperature of the adhesive differs from the set constant temperature, the system drives the temperature control plate to control the temperature of the adhesive. The liquid level detector monitors the remaining adhesive in the storage tank in real time and compares it with the remaining uncoated area of ​​the corrugated paper, and calculates the difference. If the adhesive is insufficient to completely coat the corrugated paper this time, the replenishment pipe will be driven to replenish the adhesive difference into the storage tank.

The coating mechanism stores adhesive and applies it to the corrugated paper. The coating mechanism can not only stir the adhesive loaded inside, but also adjust according to the temperature change of the adhesive to ensure that the adhesive inside the coating mechanism is always kept at a constant temperature and that the adhesive viscosity remains consistent.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Corrugated paper 3, also known as corrugated paper, is made of at least one layer of corrugated cardboard and one layer of linerboard bonded together. This embodiment uses three-layer corrugated paper as an example, that is, a layer of linerboard is laid on both sides of the corrugated paper.

[0020] This application provides a reinforced corrugated cardboard processing apparatus. This apparatus is used to process reinforced corrugated cardboard, specifically by adding a reinforcing strip 34 between the corrugated paper and the linerboard to increase the strength of the corrugated paper 3. In the prior art, a three-layer corrugated cardboard 3 includes a first cardboard 31, a second cardboard 32, and a third cardboard 33 bonded together in sequence, wherein the second cardboard 32 is a corrugated corrugated core.

[0021] Specifically, the reinforcing strip 34 can be set between the first cardboard 31 and the second cardboard 32, or between the second cardboard 32 and the third cardboard 33, or both between the first cardboard 31 and the second cardboard 32 and between the second cardboard 32 and the third cardboard 33. No specific limitation is made here.

[0022] Please see Figure 1 The processing device includes a support frame 1, a transmission mechanism 2, and an application mechanism 4. The support frame 1 supports the transmission mechanism 2 and the application mechanism 4, which are used to process corrugated paper 3. The application mechanism 4 applies adhesive to the center of the corrugated paper 3. The application mechanism 4 stores adhesive and applies it to the corrugated paper 3. The application mechanism 4 not only stirs the adhesive loaded inside but also adjusts according to the temperature changes of the adhesive, ensuring that the adhesive inside the application mechanism 4 remains at a constant temperature and that the adhesive viscosity remains consistent.

[0023] In some embodiments, such as Figure 3 As shown, the transmission mechanism 2 is mounted on the support frame 1. It is used to guide the corrugated paper 3 out of the material and control the tension of the corrugated paper 3. The corrugated paper 3 has a four-layer structure, including a first cardboard 31, a second cardboard 32, a third cardboard 33 and a reinforcing strip 34. The first cardboard 31, the second cardboard 32 and the third cardboard 33 can form a traditional corrugated paper 3, while the addition of the reinforcing strip 34 can enhance the strength of the corrugated paper 3, ensuring that the finished corrugated paper 3 has greater tensile strength and deformation resistance than the traditional corrugated paper 3.

[0024] Adding reinforcing strips 34 between different cardboard sections can improve the overall strength of the corrugated paper 3 to some extent. However, due to the limited adhesiveness of the reinforcing strips 34, their bonding stability with the cardboard sections on both sides is insufficient, making them prone to delamination or displacement. This results in the final packaging material failing to meet the requirements for load-bearing capacity and impact resistance. During processing, the coating mechanism 4 applies adhesive to the reinforcing strips 34, ensuring a tight bond between them and the first cardboard 31, the second cardboard 32, and the third cardboard 33. This prevents displacement and delamination during use, thereby stabilizing the structural strength of the reinforced corrugated paper and extending the service life of the finished product.

[0025] In addition, this design allows corrugated paper 3 to meet the corresponding strength requirements without additional lamination processes, which not only reduces the overall weight but also lowers the difficulty of recycling corrugated paper 3.

[0026] The transmission mechanism 2 includes rotating rollers 21 mounted on the support frame 1 and driven by the motor 5. There are at least three sets of rotating rollers 21. The three sets of rotating rollers 21 are used to transport the first paperboard 31, the second paperboard 32, and the third paperboard 33, respectively.

[0027] All the rotating rollers 21 are equipped with gear sets, which transmit the rotational force of the rotating rollers 21 to the coating mechanism 4. The gear sets include a first gear 22 located at one end of the rotating roller 21, a second gear 23 located outside the first gear 22, a third gear 24 located on the support frame 1, and a fourth gear 25 located on the coating mechanism 4. There is not one first gear 22, which is used to transmit the power of the motor 5 to the rotating roller 21 to drive the rotating roller 21 to rotate. The second gear 23 has the same size as the first gear 22. The third gear 24 meshes with the second gear 23, and the third gear 24 and the second gear 23 have the same size, which ensures that the third gear 24 and the second gear 23 rotate at the same speed. The third gear 24 meshes with the fourth gear 25, and the third gear 24 and the fourth gear 25 have the same size. Under this transmission, the fourth gear 25 drives the internal stirring element 46 of the coating mechanism 4 to rotate at the same speed as the rotating roller 21.

[0028] The support frame 1 is also equipped with a power chamber 11, which is used to enclose the gear set to prevent the gears from splashing and causing accidental injury or death in case of special circumstances. It can also prevent foreign objects from entering the gear set and causing the gears to jam.

[0029] During operation, motor 5 outputs rotational power, which is synchronously transmitted to each set of rotating rollers 21 through multiple first gears 22, driving the three sets of rotating rollers 21 to operate synchronously. This completes the continuous conveying of the first cardboard 31, the second cardboard 32, and the third cardboard 33, simultaneously guiding the corrugated paper 3 out of the container and controlling its tension. During operation, each set of rotating rollers 21 drives the first gear 22 at its end to rotate synchronously. The meshing transmission relationship between the first gear 22 and the second gear 23 of the same size achieves primary power transmission. The second gear 23 drives the third gear 24 of the same size, which meshes with it, to rotate at a constant speed. The third gear 24 then transmits the power to the third gear 24 of the same size and meshes with it. The meshing fourth gear 25, with its multi-stage, same-specification gear meshing transmission, eliminates speed differences, allowing the fourth gear 25 to achieve a rotational speed completely consistent with that of the rotating roller 21. This, in turn, drives the stirring component 46 inside the coating mechanism 4 to operate synchronously, achieving differential-speed linkage between the transmission mechanism 2 and the coating mechanism 4. Throughout the process, the power chamber 11 on the support frame 1 completely encloses all gear components, continuously isolating external dust, debris, and other foreign objects, preventing foreign objects from entering the gear meshing gap and causing jamming malfunctions. At the same time, it blocks splashes that may be generated during the high-speed operation of the gears, avoiding safety accidents caused by personnel contacting the operating gears, and ensuring the continuous and stable operation of the transmission mechanism 2.

[0030] In some embodiments, such as Figure 4 As shown, the coating mechanism 4 is mounted on the support frame 1. The coating mechanism 4 is connected to the transmission mechanism 2, and is driven by the transmission mechanism 2. The coating mechanism 4 is used to load adhesive and coat it onto the corrugated paper 3.

[0031] The coating mechanism 4 also includes a stirring element 46, which is used to stir the adhesive loaded in the coating mechanism 4 to ensure that the viscosity of the adhesive remains consistent. The stirring element 46 is driven to rotate by a gear set, providing power for stirring the adhesive in the coating mechanism 4. Therefore, there is no need to require additional power to start the stirring element 46, saving power consumption while utilizing the unconsumed power.

[0032] The application mechanism 4 includes a storage box 41 for storing adhesive. The storage box 41 is used to store adhesive. The outer side of the storage box 41 is provided with a transmission rod 42 connected to a gear set. The transmission rod 42 is connected to a stirring element 46. The outer end of the transmission rod 42 is connected to a fourth gear 25 and drives the rotation to rotate the stirring element 46.

[0033] The storage tank 41 is equipped with a guide roller 43, which guides the reinforcing belt 34 into the storage tank 41 to achieve contact between the reinforcing belt 34 and the adhesive. The storage tank 41 is also equipped with a discharge port 44, and a discharge roller 441 is provided at the discharge end of the discharge port 44. Both the discharge roller 441 and the guide roller 43 are rotating shafts used to change the feeding and discharge direction of the reinforcing belt 34, preventing wear on the storage tank 41 and the discharge port 44.

[0034] The stirring component 46 includes a central rod 463 mounted on the transmission rod 42. The center of the central rod 463 is the center of the stirring circle. Rotation around the central rod 463 drives the surrounding adhesive to stir. At least two support rods 464 are provided on the central rod 463 to support the outer ring stirring blades 465. The support rods 464 are equipped with the outer ring stirring blades 465, and the central rod 463 also has inner ring stirring blades 466. A central stirring blade 467 is located in the middle of the central rod 463. Figure 8 As shown, the stirring direction of the outer ring stirring blade 465 is the middle section of the second transmission member 462, while the stirring direction of the inner ring stirring blade 466 is the direction of the two connecting ends of the central rod 463.

[0035] A rotating component 461 is provided on the central rod 463. The rotating component 461 is used to connect to the storage box 41 to allow the central rod 463 to rotate and reduce the friction between the central rod 463 and the storage box 41.

[0036] Furthermore, such as Figure 8 As shown, the outer ring stirring blades 465 and the inner ring stirring blades 466 are arranged in two sets, mirror-image opposite each other on the central rod 463. This design allows the two outer ring stirring blades 465 to drive the stirring towards the center of the storage tank 41, causing the adhesive on both sides to converge at the position of the synchronous guide 47 and collide. This ensures thorough stirring, and the thorough collision allows the adhesive to gather near the synchronous guide 47, enabling the reinforcing belt 34 to have more complete contact with the adhesive.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, the outer ring stirring blades 465 and inner ring stirring blades 466 stir the adhesive in opposite directions. The two outer ring stirring blades 465 stir the adhesive towards the center of the central rod 463. The two inner ring stirring blades 466 stir the adhesive towards both ends of the central rod 463. The central stirring blade 467 stirs the adhesive in the middle of the central rod 463. When the outer ring stirring blades 465 push and stir the adhesive towards the synchronous guide 47, the adhesive on both sides collides, but the outermost adhesive does not collide; it only moves inward. At this time, the inner ring stirring blades 466 pump the adhesive near the central rod 463 towards the second transmission member 462 for stirring and transport. This staggered, opposite-direction stirring method allows for more thorough mixing of the adhesive, and the central stirring blade 467 stirs the adhesive pushed towards the synchronous guide 47 by the outer ring stirring blades 465. The three sets of stirring blades, impacting the adhesive, the staggered, opposite-direction flow, and the central rotation stirring, combined with these three stirring methods, ensure thorough mixing of the adhesive. Since the adhesive is a gel-like substance with high viscosity, using a combination of three mixing methods can effectively prevent any unmixed parts from being left unmixed.

[0038] like Figure 6 As shown, the coating mechanism 4 also includes an applicator 45 located on one side of the storage box 41. The applicator 45 is a cylindrical roller that contacts the inner sides of the first cardboard 31, the second cardboard 32, and the third cardboard 33. Through contact with the corrugated cardboard 3, it rotates, thereby achieving the glue application step. The applicator 45 is equipped with an application roller 451, and the two ends of the application roller 451 are equipped with first transmission components 452.

[0039] A second transmission member 462 is located at the same longitudinal position as the central rod 463 and the first transmission member 452. A toothed belt 48 is sleeved on both the second transmission member 462 and the first transmission member 452. Both the first transmission member 452 and the second transmission member 462 are gears, while the inner side of the toothed belt 48 has serrations. This allows for transmission even when the adhesive is not fully cured in the storage box 41, preventing the second transmission member 462 and the first transmission member 452 from sticking together. The toothed belt 48 meshes with the second transmission member 462 and the first transmission member 452, a design that prevents the toothed belt 48 from slipping, thus enhancing the stability of the transmission.

[0040] A synchronous guide 47 is provided in the middle of the center rod 463. The synchronous guide 47 is used to guide the direction of the reinforcing strip 34 included in the corrugated paper 3. Limiting plates 471 are provided at both ends of the synchronous guide 47 to limit the reinforcing strip 34. The rotation speed of the synchronous guide 47 is the same as that of the rotating roller 21, thereby ensuring that the output speed of the first paperboard 31 and the output speed of the reinforcing strip 34 are the same, and that uneven tension inside the corrugated paper 3 will not occur due to speed difference.

[0041] The inner wall of the storage tank 41 is hollow, and a temperature regulating plate is installed on its inner side. The temperature regulating plate is controlled by the system and electrically connected to a temperature detector. It is used to ensure that the adhesive in the storage tank 41 is always kept at a constant temperature. The temperature regulating plate is a semiconductor temperature control plate that integrates heating and cooling functions. When the adhesive temperature is lower than the set value, the heating mode is activated; when it is higher than the set value, the cooling mode is activated. The storage tank 41 is also equipped with a liquid level detector 411 for detecting the liquid level of the adhesive stored in the storage tank 41. The liquid level detector 411 is electrically connected to the replenishment pump of the external unit of the replenishment pipe 412. If the adhesive in the storage tank 41 is insufficient, the replenishment pump automatically replenishes the storage tank 41. The replenishment pipe 412 is connected to the liquid level detector 411. A temperature detector is installed at the bottom of the storage tank 41. A viscosity detector is installed at the end of the support rod 464 to monitor the viscosity of the adhesive in the storage tank 41 in real time. The viscosity detector detects the viscosity of the adhesive in real time. When the viscosity exceeds the preset range, the control system adjusts the adhesive temperature through the temperature regulating plate to restore the viscosity to the normal range. There are two coating mechanisms 4, which apply adhesive to the side of the first cardboard 31 near the second cardboard 32 and the side of the second cardboard 32 near the third cardboard 33, respectively. Only one coating mechanism 4 is shown in the accompanying drawings. The actual device is equipped with at least two coating mechanisms 4. The other coating mechanism 4 is omitted in the drawings for simplification and does not affect the complete disclosure of the technical solution.

[0042] When the applicator 4 is running, the fourth gear 25 of the transmission mechanism 2 drives the transmission rod 42, which is rigidly connected to it, to rotate coaxially. The transmission rod 42 further drives the central rod 463 of the stirring component 46 to rotate synchronously around the axis. The central rod 463 drives the outer ring stirring blades 465 to rotate through at least two support rods 464, and at the same time directly drives the inner ring stirring blades 466 and the central stirring blades 467 to rotate. The two sets of mirror-arranged outer ring stirring blades 465 push the adhesive on both sides of the storage tank 41 towards the center synchronously, so that the adhesive on both sides collides and mixes at the synchronous guide 47. The two sets of inner ring stirring blades 466 push the adhesive in the central area towards both ends of the central rod 463, forming a bidirectional convection circulation. The central stirring blades 467 perform secondary shearing and stirring on the adhesive that converges in the middle, eliminating the stirring dead corners that are easy to occur in viscous adhesive. When the central rod 463 rotates, the second transmission component 462 on its surface drives the first transmission component 452 at both ends of the applicator 45 to rotate synchronously through the toothed belt 48 with serrations on the inner side, thereby driving the applicator roller 45. 1. Rotation: The meshing transmission between the toothed belt 48 and the transmission component is not affected by the adhesive adhesion, avoiding slippage; The synchronous guide 47, fixed in the middle of the central rod 463, rotates at the same speed as the central rod 463, guiding the reinforcing belt 34 to be conveyed at a uniform speed; The limiting plates 471 at both ends restrict the lateral displacement of the reinforcing belt 34, so that the conveying speed of the reinforcing belt 34 is completely consistent with the conveying speed of the rotating roller 21; The two coating mechanisms 4 correspond to the bonding surfaces of the first paperboard 31 and the second paperboard 32, and the second paperboard 32 and the third paperboard 33, respectively, to complete double-sided coating; During operation, the temperature detector at the bottom of the storage tank 41 collects the adhesive temperature in real time and transmits it to the control system. The control system drives the temperature regulating plate in the hollow inner wall to adjust the temperature and maintain the constant temperature of the adhesive; The viscosity detector at the end of the support rod 464 monitors the viscosity change of the adhesive in real time; The liquid level detector 411 detects the liquid level of the adhesive in real time and transmits the data to the control system. The control system calculates the amount of adhesive required for the remaining coating area. When the amount is insufficient, it drives the external replenishing pump of the replenishing pipe 412 to automatically replenish the adhesive.

[0043] A method for processing reinforced corrugated cardboard includes the following steps: After the previous batch of reinforced corrugated paper 3 production is completed, the operator will thoroughly empty and clean the storage box 41 of the coating mechanism 4, cleaning the residual adhesive on the inner wall, bottom and gaps of each component of the storage box 41 one by one, and removing any impurities that may exist in the box, to ensure that the inside of the storage box 41 is clean and free of residue, thus avoiding cross-contamination between different batches of adhesive from the source and ensuring the stability of the performance of the adhesive used in this production.

[0044] After cleaning and preparing the storage tank 41, the operator connects and fixes the initial ends of the corrugated paper 3 used in this processing to the corresponding positions of the transmission mechanism 2. Simultaneously, the reinforcing tape 34 is wound and installed inside the coating mechanism 4 according to the prescribed path. Then, the operator inputs the various process parameters for the corrugated cardboard to be produced and the preset constant adhesive temperature value into the control system of the processing device. The system automatically calls the built-in mathematical model of adhesive consumption and, combined with the input parameters, accurately calculates the total amount of adhesive required for this batch of production. After the calculation is completed, the control system automatically sends a command to the external feed pump of the feed pipe 412, controlling the feed pump to add adhesive to the storage tank 41, strictly controlling the amount added to ensure that the final total amount of adhesive added perfectly matches the total amount of adhesive calculated by the mathematical model. At this time, the newly added adhesive is in a stable and active period, requiring no prior stirring. After all pre-production preparations are completed, the motor 5 is turned on, driving the coating mechanism 4 through the transmission mechanism 2, which in turn drives the stirring components inside the coating mechanism 4 to begin stirring the adhesive.

[0045] After starting the reinforced corrugated cardboard processing device, the entire machine enters the preset automatic operation state. The motor 5 outputs stable power to drive the transmission mechanism 2 to start rotating at a uniform speed. The gear set on the transmission mechanism 2 achieves the transmission of power at the same speed through sequential meshing, transmitting the rotational force to the coating mechanism 4 without any difference in speed, causing the coating mechanism 4 to maintain a completely consistent operating rhythm with the transmission mechanism 2. After receiving power, the coating mechanism 4 drives the central rod 463 of its internal stirring component 46 to rotate synchronously around the axis, thereby driving the outer ring stirring blade 465 and the inner ring stirring blade 466, which are fixedly installed on the central rod 463, to rotate together. During the rotation, the outer ring stirring blade 465 and the inner ring stirring blade 466 push the adhesive in the storage tank 41 to continuously flow and stir towards the synchronous guide 47 in the middle of the central rod 463 according to the preset stirring direction. At the same time, the synchronous guide 47, which rotates synchronously with the central rod 463, drives the reinforcing belt 34 to drive at a uniform speed, ensuring that the conveying rhythm of the reinforcing belt 34 matches the overall processing flow.

[0046] The coating mechanism 4 includes an applicator 45 fixedly mounted on one side of the storage tank 41, which performs the core processing function of this step. The applicator 45 first applies adhesive to the inner surface of the corrugated paper 3, which is conveyed at a constant speed to the processing station, ensuring that the adhesive evenly covers the area to be laminated. After adhesive application, the station where the applicator 45 is located tightly bonds the reinforcing belt 34, which is conveyed synchronously, to the adhesive-coated corrugated paper 3, initially integrating the reinforcing belt 34 and the corrugated paper 3. After adhesive application, the reinforcing belt 34 is then tightly bonded to the adhesive-coated corrugated paper at the subsequent pressing station using pressing rollers. After the reinforcing belt 34 and the corrugated paper 3 are fully fused, this station also performs quality inspection and drying treatments on the laminated corrugated paper 3 semi-finished product to ensure rapid adhesive curing and guarantee the stability of the composite structure.

[0047] In some embodiments, the temperature detector continuously monitors the temperature of the adhesive within the storage tank 41 in real time, accurately capturing temperature changes caused by various environmental factors. The temperature detector synchronously feeds back the collected real-time adhesive temperature data to the control system of the processing device. The control system automatically and continuously compares this real-time temperature with a pre-set constant adhesive temperature. When any positive or negative difference is detected between the actual adhesive temperature and the set constant temperature, the control system immediately outputs a corresponding control signal, driving the temperature regulating plate inside the storage tank 41 to initiate a temperature adjustment program, precisely controlling the temperature of the adhesive within the storage tank 41 until its temperature recovers and stabilizes at the set constant temperature value.

[0048] Furthermore, the liquid level detector 411 continuously monitors the remaining adhesive level in the storage tank 41 in real time and transmits the collected real-time liquid level data synchronously to the control system of the processing device. The control system synchronously retrieves the processing progress data of the current batch of corrugated paper 3, automatically calculates the total area of ​​the corrugated paper 3 that has not been coated with adhesive, and then, combined with the preset adhesive consumption standard per unit area, calculates the amount of adhesive required to complete all remaining adhesive coating operations. The control system accurately compares the actual amount of remaining adhesive in the storage tank 41 with the amount of adhesive required to complete the remaining processing and automatically calculates the difference between the two values. When the comparison and calculation results show that the remaining adhesive in the storage tank 41 is insufficient to completely coat all the corrugated paper 3 processed in this operation, the control system immediately outputs a precise replenishment control signal, driving the replenishment pipe 412, which is linked to the liquid level detector 411, to replenish the storage tank 41 with an amount of adhesive exactly equal to the calculated difference, ensuring that the adhesive coating operation can be carried out continuously and without interruption.

[0049] When using the reinforced corrugated cardboard processing device, the operator emptys and cleans the storage tank 41 of the coating mechanism 4, removing any residual adhesive and impurities. The operator connects the initial end of the corrugated cardboard 3 to the transmission mechanism 2, and winds the reinforcing tape 34 into the coating mechanism 4. The operator inputs the parameters for this corrugated cardboard production and the constant temperature of the adhesive into the processing device control system. The control system calls the built-in adhesive consumption mathematical model to calculate the total amount of adhesive required for this production, and controls the external feed pump of the feed pipe 412 to add adhesive matching the calculated total amount into the storage tank 41. At this time, the stirring operation is not started. The motor 5 is turned on, and the motor 5 drives the rotating roller 21 of the transmission mechanism 2 to rotate. At least three sets of rotating rollers 21 respectively transport the first cardboard 31, The second cardboard 32 and the third cardboard 33 guide the corrugated paper 3 out of the container and control the tension of the corrugated paper 3. The first gear 22 at one end of the roller 21 drives the second gear 23 to rotate, the second gear 23 drives the third gear 24 meshing with it to rotate, and the third gear 24 drives the fourth gear 25 meshing with it to rotate. The first gear 22, the second gear 23, the third gear 24, and the fourth gear 25 are of the same size, so as to achieve the same speed power transmission. The power chamber 11 on the support frame 1 encloses the above gear set. The fourth gear 25 drives the transmission rod 42 of the coating mechanism 4 to rotate. The transmission rod 42 drives the central rod 463 of the stirring component 46 to rotate around the axis. The support rod 464 on the central rod 463 drives the outer ring stirring blade 465 to rotate. The central rod 463 simultaneously drives the inner ring stirring blade 465 to rotate. The mixing blades 466 and the central mixing blade 467 rotate. Two sets of mirror-image opposing outer ring mixing blades 465 stir the adhesive towards the center of the central rod 463, while two sets of inner ring mixing blades 466 stir the adhesive towards both ends of the central rod 463. The central mixing blade 467 stirs the adhesive in the middle of the central rod 463. The synchronous guide 47 in the middle of the central rod 463 rotates synchronously with the central rod 463, guiding and driving the reinforcing belt 34 to rotate. The limiting plates 471 at both ends of the synchronous guide 47 limit the reinforcing belt 34. The rotation speed of the synchronous guide 47 is the same as the rotation speed of the rotating roller 21. The second transmission component 462 on the central rod 463 drives the first transmission component 452 of the applicator 45 to rotate via the toothed belt 48. The coating roller 451 rotates and applies adhesive to the inside of the corrugated paper 3. The reinforcing belt 34 fuses with the corrugated paper 3 after the adhesive is applied. After the fusion is completed, the corrugated paper 3 semi-finished product is inspected and dried. The two coating mechanisms 4 apply adhesive to the side of the first cardboard 31 near the second cardboard 32 and the side of the second cardboard 32 near the third cardboard 33, respectively. The temperature detector at the bottom of the storage box 41 detects the temperature of the adhesive in real time and transmits the temperature data to the control system. The control system compares the real-time temperature with the set constant temperature. When there is a difference, the temperature regulating plate inside the storage box 41 is driven to adjust the temperature of the adhesive to the set constant temperature. The viscosity detector at the end of the support rod 464 detects the viscosity of the adhesive in real time.The liquid level detector 411 monitors the remaining adhesive level in the storage tank 41 in real time and transmits the liquid level data to the control system. The control system calculates the required amount of adhesive corresponding to the remaining uncoated area of ​​the corrugated paper 3, compares the actual amount of remaining adhesive with the required amount, and calculates the difference. When the remaining adhesive is insufficient to complete the coating operation of all the corrugated paper 3, the replenishment pipe 412 is driven to replenish the storage tank 41 with an amount of adhesive equal to the difference.
