Description

Technical Field

[0001] The present application relates to the technical field of paper tube base paper detection, and in particular to an integrated intelligent paper tube base paper detection device and detection method. Background Art

[0002] The quality of paper tube base paper is directly related to the performance and user experience of paper products. Therefore, systematic testing of its quality is an indispensable key link in the production process. Traditional testing methods mostly rely on manual visual observation or simple physical measurements. Such methods are not only inefficient, but also difficult to accurately identify all potential quality risks. From the production practice, the thickness of the paper will directly affect the thickness uniformity of the base paper after it is wound into a paper tube, and insufficient tensile strength of the base paper may cause the wound paper tube to break during use. Based on this, key parameters such as paper thickness and tensile strength need to be controlled through a multi-dimensional precision monitoring system to ensure that the quality of the paper tube base paper meets the production application requirements.

[0003] For example, patent application number CN221527571U discloses a paper thickness detection device, which belongs to the field of paper thickness detection technology and aims to solve the problem of paper deflection caused by the movement of the pressure plate and the impact of cam rotation on reading accuracy. The device utilizes a design of threaded rods, gears, and a toothed ring to achieve synchronous rotation of the three threaded rods when the toothed ring rotates, driving the contact plate to move up and down, completing the squeezing and positioning of the paper. Furthermore, the top hole allows the air above the paper to be expelled when the contact plate presses down on the paper, preventing paper deflection and ensuring accurate detection results.

[0004] Although the above patent application has made some innovations in paper thickness detection technology, it still has obvious limitations in actual application scenarios: its function is relatively single and can only complete paper thickness detection processing. It is difficult to integrate with other paper quality detection links, such as paper tensile strength detection, and cannot meet the needs of modern papermaking enterprises for multifunctional integrated detection equipment.

[0005] In terms of data acquisition, the detection method adopted in this patent relies on the combination of a measuring ruler and a pointer. This traditional mechanical measurement method is not only cumbersome and susceptible to human interference, but also incapable of automatic data collection, storage, and analysis. It cannot effectively integrate with existing intelligent manufacturing systems, making it difficult to meet intelligent production management requirements such as real-time monitoring, big data analysis, and remote control. Its overall level of intelligence lags significantly behind cutting-edge industry technologies. Summary of the Invention

[0037] The following is combined with Figures 1 to 10 This application is described in further detail.

[0038] The embodiments of the present application disclose an integrated intelligent paper tube base paper detection device and detection method, which can perform flatness and tensile strength tests on paper in an integrated manner. Example

[0039] Reference Figure 1 as well as Figure 2 An integrated intelligent paper tube base paper detection device includes a horizontal frame 1, on which a pretreatment mechanism 2 and a flatness detection mechanism 3 are sequentially installed along the length direction thereof, wherein the flatness detection mechanism 3 includes: There are two leveling rollers 31 , which are symmetrically distributed along the length direction of the horizontal frame 1 .

[0040] There are two coating rollers 32 , which are symmetrically distributed along the length direction of the horizontal frame 1 , and the coating rollers 32 are provided with corresponding feeding components 33 .

[0041] The camera 34 is arranged above the flattening roller 31 away from the pre-processing mechanism 2 and is used to detect the flatness of the paper.

[0042] Two sets of fixed frames are symmetrically installed on the horizontal frame 1 along its length direction, and each set of fixed frames is symmetrically arranged along the width direction of the horizontal frame 1, and a winding roller is detachably installed inside each set of fixed frames, that is, fixed connecting blocks matching with the winding roller are arranged at both ends of the winding roller, and the two ends of the winding roller are rotatably installed on the fixed connecting blocks on the corresponding sides through bearings, and the fixed connecting blocks are limitedly slidably arranged on the corresponding fixed frames, and the fixed connecting blocks will not slide out of the fixed frames during the paper detection process, wherein the arrows (such as Figure 1 (as shown) is the paper moving direction for flatness detection.

[0043] During specific operation, the paper is wound around the winding roller close to the pretreatment mechanism 2, and then the paper is passed through the top of the leveling roller 31 and the bottom of the coating roller 32 in sequence, and finally the paper is wound around the winding roller away from the pretreatment mechanism 2. At this time, the paper passes through the inside of the pretreatment mechanism 2, and the coating roller 32 close to the pretreatment mechanism 2 is coated with colorless phenolphthalein solution to fully cover the paper. The coating roller 32 away from the pretreatment mechanism 2 is coated with alkaline solution (sodium hydroxide solution, etc.) to the paper. Finally, the color change of the paper surface is recorded by the camera 34, and the flatness of the paper is observed.

[0044] The leveling roller 31 can keep the paper on the upper side always on a horizontal surface, thus preventing the paper from tilting and affecting the coating accuracy.

[0045] Reference Figures 3 to 6 The pretreatment mechanism 2 provided by the present invention fully flattens the paper through pre-pressing treatment, eliminates the internal stress of the rolled paper, and prevents the surface flatness from being affected by curling and resetting in the subsequent coating process. The pretreatment mechanism 2 includes two groups of vertical frames 21 distributed along the length direction of the horizontal frame 1 and having an inverted L-shaped structure, and each group of vertical frames 21 is symmetrically distributed along the width direction of the horizontal frame 1 and its vertical sections are installed on the horizontal frame 1, and processing rollers 22 are rotatably installed between each group of vertical frames 21 through bearings, and the bottom of the horizontal section of the vertical frame 21 close to the flatness detection mechanism 3 is installed with a telescopic cylinder 23 through a cylinder seat, and the bottom of the telescopic end of the telescopic cylinder 23 is installed with a lifting roller 24 through a connecting block, and the bottom of the horizontal section of the vertical frame 21 away from the flatness detection mechanism 3 is installed with an elastic telescopic rod 25, and the bottom of the telescopic end of the elastic telescopic rod 25 is installed with a tensioning roller 26 through a connecting block.

[0046] A pressing roller 27 is also provided between the lifting roller 24 and the tensioning roller 26. A reciprocating plate 28 is provided between the two adjacent vertical frames 21 in the length direction of the horizontal frame 1, and both ends of the pressing roller 27 are rotatably mounted on the reciprocating plate 28 on the corresponding side through bearings. A horizontal connecting rod 29 is slidingly provided through the reciprocating plate 28 along its length direction, and both ends of the horizontal connecting rod 29 are provided on the vertical frame 21 on the corresponding side. A rack plate 20 is installed on the back side of the reciprocating plate 28, and a vertical connecting frame 210 is installed on the horizontal frame 1 through a support protrusion. A linkage shaft 211 is installed on the vertical connecting frame 210 through a bearing, and a gear 212 meshing with the rack plate 20 on the corresponding side is installed on the linkage shaft 211.

[0047] The process roller 22 farther from the leveling roller 31 corresponds to the tensioning roller 26, while the process roller 22 closer to the leveling roller 31 corresponds to the lifting roller 24. The winding roller is positioned higher than the tensioning roller 26 and the process roller 22. During operation, the paper is sequentially passed through the gaps between the process roller 22 and the tensioning roller 26, and then the gaps between the process roller 22 and the lifting roller 24. At this point, the winding roller farther from the pre-processing mechanism 2 rotates under an external drive force (such as a motor) to begin winding the paper. As the paper passes through the pre-processing mechanism 2, the winding roller is positioned higher than the tensioning roller 26, allowing it to adhere to the lower sidewall of the tensioning roller 26. The tensioning roller 26 and the elastic retractable rod 25 work together to ensure that the paper remains taut. Furthermore, as the paper moves beneath the tensioning roller 26, it is passively pressed by the tensioning roller 26 to eliminate internal stress in the wound paper. This prevents curling of the paper during subsequent testing, which could lead to misjudgments.

[0048] When a sheet of paper enters between the two processing rollers 22, an external driving force (such as a servo motor) drives the linkage shaft 211 to reciprocate (i.e., the servo motor rotates forward a certain number of times and then reverses a certain number of times). It should be noted that the gear 212 is always meshed with the rack plate 20. The reciprocating rotation of the linkage shaft 211 drives the gear 212 to rotate synchronously. The gear 212, through its meshing with the rack plate 20, drives the reciprocating plate 28 to slide back and forth along the horizontal connecting rod 29. The reciprocating motion of the reciprocating plate 28, in turn, drives the pressing roller 27 to actively press the paper, further eliminating internal stress in the paper.

[0049] By combining the passive pressing of the tensioning roller 26 with the active pressing of the pressing roller 27, the paper is subjected to a double pressing treatment, and then cooperates with the lifting roller 27 to form a triple flattening effect. This synergistic mechanism effectively reduces the risk of deformation of the paper due to internal stress.

[0050] When the paper moves between the lifting roller 24 and its corresponding processing roller 22, the telescopic cylinder 23 is activated. The cylinder's telescopic end, through a connecting block, drives the lifting roller 24 downward, pressing the paper tightly against the corresponding processing roller 22. This squeezing action rigidly shapes the wrinkle-removed paper, effectively reducing the possibility of curling and restoring due to internal stress. Simultaneously, the lifting roller 24 and the processing roller 22 rigidly limit the paper, ensuring a stable entry into the subsequent flatness detection mechanism 3. This prevents the paper from shaking as it enters the coating roller 32, which could result in uneven coating, and ensures a uniform coating effect.

[0051] During the paper pulling process, an external friction force needs to be applied to the winding roller wrapped with the paper to control the rotation speed of the corresponding winding roller during the paper movement process, so as to prevent the paper from falling off the winding roller due to excessive paper movement speed.

[0052] Reference Figure 6 as well as Figure 7 In order to eliminate wrinkles on paper, the present invention provides a reciprocating sleeve 271 that can flatten the wrinkles on the paper. Specifically, the circumferential surface of the pressing roller 27 is symmetrically provided with automatically reset reciprocating sleeves 271 along its length direction, and the reciprocating sleeves 271 are limitedly slidingly set on the circumferential surface of the pressing roller 27. The driving component 4 is jointly installed on the vertical frame 21. Both ends of the pressing roller 27 are provided with reset springs 272, and the reset springs 272 are installed on the reciprocating plate 28 on the corresponding side. The end of the reset spring 272 away from the reciprocating plate 28 on the corresponding side is provided with a reset ring 273 for resetting the reciprocating sleeve 271.

[0053] The driving assembly 4 includes two driving frames 41 which are symmetrically arranged along the width direction of the horizontal frame 1 and correspond one-to-one to the reciprocating sleeve 271. Connecting rods 42 are symmetrically installed on the driving frames 41 along their length direction. The end of the connecting rod 42 away from the corresponding driving frame 41 is installed on the vertical frame 21 on the corresponding side. A profile frame 43 which corresponds one-to-one to the reciprocating sleeve 271 and opens downward is arranged between the two driving frames 41. The bottoms of the two vertical sections of the profile frame 43 are located on both sides of the pressing roller 27, and the distance between the two vertical sections of the profile frame 43 is smaller than the diameter of the reciprocating sleeve 271 to ensure that the two vertical sections of the profile frame 43 can drive the reciprocating sleeve 271 to move.

[0054] A driving link 44 is installed on the horizontal section of the C-shaped frame 43 and is slidably arranged on the corresponding side driving machine frame 41. One end of the driving link 44 away from the corresponding side C-shaped frame 43 is provided with a driving connecting block 45 that cooperates with the side wall of the corresponding side driving machine frame 41. A plurality of adjusting blocks 46 are evenly arranged along the length direction on the opposite side of the driving machine frame 41, and the driving connecting block 45 can move along the side of the adjusting block 46. A limiting plate 47 for limiting the driving link 44 is also installed on the driving machine frame 41. A sliding block 48 is slidably arranged on the limiting plate 47, and a telescopic spring rod 49 is jointly installed between the sliding block 48 and the horizontal section of the corresponding side C-shaped frame 43.

[0055] The adjusting block 46 is of an isosceles trapezoid structure. During specific operation, when the pressing roller 27 reciprocates to press the paper, the pressing roller 27 drives the C-shaped frame 43 to move synchronously. The movement of the C-shaped frame 43 further drives the driving link 44 connected to it to move. The driving link 44 drives the driving connecting block 45 to move, and the driving connecting block 45 is blocked by the adjusting block 46 on its moving path. Constrained by this limit, the driving connecting block 45 is forced to move along the side wall of the adjusting block 46. This movement is transmitted through the driving link 44 to force the C-shaped frame 43 to move towards the vertical frame 21 side (that is, the two C-shaped frames 43 move away from each other). The movement away from each other of the C-shaped frame 43 drives the reciprocating sleeve 271 connected to it to move away from each other synchronously. During the movement away from each other of the reciprocating sleeve 271, it can exert opposite forces on the paper along its width direction, making the paper tend to flatten on both sides, thus effectively reducing the possibility of the paper wrinkling.

[0056] At the same time, the movement away from each other of the reciprocating sleeve 271 compresses the corresponding side return spring 272 through the return ring 273. At the same time, the movement of the C-shaped frame 43 also compresses the telescopic spring rod 49. When the driving connecting block 45 moves along the side wall of the adjusting block 46 to its edge and starts to move towards the other side wall of the adjusting block 46, the driving connecting block 45 gets out of the constraint of the adjusting block 46. At this time, the compressed return spring 272 loses the external force and starts to reset. The extension force of the return spring 272 pushes the reciprocating sleeve 271 to reset through the return ring 273. Synchronously, the restoring force of the telescopic spring rod 49 also drives the C-shaped frame 43 to reset. When the C-shaped frame 43 resets, it带动 the driving connecting block 45 to reset together through the driving link 44. When the driving connecting block 45 resets and moves to the area between the two adjusting blocks 46, the above actions are repeated in a cycle. Therefore, the C-shaped frame 43 and the return spring 272 cooperate to drive the reciprocating sleeve 271 to reciprocate along the length direction of the pressing roller 27, realizing the flattening treatment of the paper wrinkles.

[0057] The limit plate 47 constrains the movement of the drive link 44, preventing it from deflecting when the mold frame 43 drives the drive link 44. Simultaneously, as the mold frame 43 moves along the length of the paper, the telescopic spring rod 49 drives the sliding block 48 to move synchronously. The sliding block 48 cooperates with the telescopic spring rod 49 to provide a reset guide during the movement of the mold frame 43.

[0058] Reference Figure 7 A plurality of flattened rings 2711 are evenly arranged on the circumferential surface of the reciprocating sleeve 271 along its length direction, and a guiding inclined surface is provided on the mold frame 43 close to the corresponding side of the flattened ring 2711.

[0059] During specific operation, when the reciprocating sleeve 271 moves in opposite directions, the flattening ring 2711 directly acts on the surface of the paper to flatten its wrinkles. When the reciprocating sleeve 271 is reset, the guide slope on it significantly reduces the contact area with the paper, effectively preventing the flattening ring 2711 from re-hooking up or returning the flattened wrinkles during the reset process, thereby ensuring the stability of the flattening effect.

[0060] Reference Figure 8 as well as Figure 9 After the paper pretreatment is completed, it is subjected to a flatness inspection. Specifically, a support frame 11 is symmetrically installed on the horizontal frame 1 along its width direction, and both ends of the leveling roller 31 are rotatably installed on the support frame 11 on the corresponding side through bearings. A support block 12 for cooperating with the coating roller 32 is installed on the support frame 11, and both ends of the coating roller 32 are rotatably installed on the support block 12 on the corresponding side through bearings. A connecting plate 13 is commonly installed on the support blocks 12 corresponding to the same support frame 11, and the feeding assembly 33 is installed between the connecting plates 13.

[0061] The feeding assembly 33 includes a storage box 331 that corresponds one-to-one to the paint roller 32 and opens upward, and the discharge port of the storage box 331 is opposite to the paint roller 32. The connecting plate 13 is located between the two storage boxes 331 and is rotatably installed with a rotating shaft 332 through a bearing, and a plurality of blades 333 are evenly arranged on the rotating shaft 332 along its circumference. A recovery part 334 is jointly installed between the storage box 331 and the paint roller 32 near the pretreatment mechanism 2.

[0062] The coating roller 32 is provided with an annular sponge, and the annular sponge on the coating roller 32 close to the pretreatment mechanism 2 is thicker than the annular sponge on the coating roller 32 away from the pretreatment mechanism 2. A mounting frame is jointly installed on the connecting plate 13, and a plurality of cameras are provided and installed on the mounting frame. During specific operation, the absorption sponge 335 is in contact with the annular sponge, and a colorless phenolphthalein solution is poured into the storage box 331 close to the pretreatment mechanism 2, and an alkaline solution is poured into the storage box 331 away from the pretreatment mechanism 2. When the colorless phenolphthalein solution is applied, the colorless phenolphthalein solution is immersed into the annular sponge through the discharge port in the storage box 331. It should be noted that the discharge port of the storage box 331 is small enough to avoid excessive single discharge of the storage box 331, which causes the annular sponge to be unable to fully absorb the solution, resulting in leakage of the solution.

[0063] The height of the leveling roller 31 is greater than that of the lifting roller 24 and the winding roller. When the paper passes through the thicker annular sponge, the surface of the paper is in full contact with the annular sponge, and there is a certain pressure between the paper and the corresponding annular sponge, so that the paper can be fully coated with the colorless phenolphthalein solution to avoid dead corners on the paper surface. When the winding roller wraps around the paper during the paper's advancement, the paper has a tensile force. Because the lifting roller 24 rigidly presses the paper, the paper has a large tensile force on the contact surface of the corresponding leveling roller 31. The paper is further stretched on the contact surface of the leveling roller 31 to ensure that the creases on the paper can be fully unfolded, thereby ensuring that the colorless phenolphthalein solution can fully contact the paper.

[0064] The paper coated with the colorless phenolphthalein solution continues to move. When the paper moves to the coating roller 32 corresponding to the alkaline solution, the alkaline solution penetrates into the inside of the annular sponge through the discharge port to coat the paper with the alkaline solution. It should be noted that the distance from the bottom of the corresponding annular sponge to the paper is the maximum acceptable error of the surface flatness of the paper, that is, the flatness of the paper less than this value is qualified, otherwise it is unqualified.

[0065] Therefore, when the coating roller 32 is applying the alkaline solution, if there is a protrusion on the paper surface that is larger than the maximum acceptable error, the colorless phenolphthalein solution on the protrusion will turn red when it comes into contact with the alkaline solution, and the other uncolored areas have a qualified flatness.

[0066] When the coating roller 32 is coating the paper, there is always a certain pressure between the coating roller 32 and the surface of the paper, thereby ensuring that the coating is evenly coated on the paper.

[0067] After applying the alkaline solution, the color change of the paper is photographed by the camera 34, and finally the data is uniformly analyzed and processed to convert the microscopic flatness into macroscopic color change, so as to detect the flatness of the paper more intuitively.

[0068] When applying the colorless phenolphthalein solution, due to the certain pressure between the annular sponge and the paper, the colorless phenolphthalein solution inside the annular sponge may be squeezed out due to the squeezing and deformation of the annular sponge. The recovery part 334 provided by the present invention can collect and process the excess colorless phenolphthalein solution. Specifically, the recovery part 334 includes an absorption sponge 335 arranged on both sides of the corresponding coating roller 32, and both ends of the absorption sponge 335 are installed on the support block 12 on the corresponding side. The absorption sponge 335 and the inner wall of the corresponding storage box 331 are jointly installed with a plurality of transition sponges 336 evenly distributed along the length direction of the storage box 331, and the end of the transition sponge 336 away from the corresponding storage box 331 is installed on the absorption sponge 335.

[0069] One end of the transition sponge 336 located inside the storage box 331 is set as a block structure, and a rotating rod 337 is rotatably installed inside the corresponding storage box 331 through a bearing, and a cam block 338 that cooperates with the transition sponge 336 is installed on the rotating rod 337.

[0070] During operation, the corresponding annular sponge and paper are squeezed and deformed, causing excess phenolphthalein solution to be squeezed out of the annular sponge. After being squeezed out, the phenolphthalein solution enters the recycling sponge. When the recycling sponge is filled with the phenolphthalein solution, it moves through the transition sponge 336 to the corresponding storage box 331. When the transition sponge 336 is filled with the phenolphthalein solution, the existing drive (such as a motor) drives the rotating rod 337 to rotate. This rotation of the rotating rod 337 drives the cam block 338 to rotate circumferentially around the rotating rod 337. During this rotation, the cam block 338 squeezes the block structure on the transition sponge 336, squeezing the phenolphthalein solution out of the block structure of the transition sponge 336. As the cam block 338 continues to rotate and disengages the contact area, the solution content in the squeezed block structure decreases significantly, forming a significant liquid level difference with the rest of the transition sponge 336. Due to the principles of capillary action and pressure difference, excess solution in other areas of the transition sponge 336 is automatically replenished into the squeezed block structure. The colorless phenolphthalein solution in the sponge can be continuously and effectively collected and recovered through the mechanical action of periodic squeezing and replenishing.

[0071] Either end of the rotating shaft 332 passes through the corresponding material storage 331 and the connecting plate 13. The rotating rod 337 passes through the connecting plate 13. The rotating shaft 332 and the rotating rod 337 are connected by a belt drive. When the rotating rod 337 rotates, the belt drive drives the rotating shaft 332 to rotate. When the rotating shaft 332 rotates, the blade 333 is driven to rotate. The rotation of the blade 333 accelerates the airflow velocity near the paper surface, so that the colorless phenolphthalein solution on the paper surface remains in a suitable moist state, thereby preventing drying and overflow.

[0072] This state ensures that the phenolphthalein solution can precisely coordinate with the subsequently applied alkaline solution at specific locations. By maintaining the phenolphthalein solution in a stable state (not flowing), unintended contact between the alkaline solution and the flowing phenolphthalein solution is effectively avoided, thereby ensuring that detection accuracy is not affected. Furthermore, the airflow generated by the rotation of blades 333 causes a small amount of phenolphthalein solution on the paper to flow slightly. This flow helps redistribute the solution across the paper surface, rewetting any areas that may have been insufficiently covered during the application process, thereby ensuring uniform application of the phenolphthalein solution to the paper.

[0073] Example 2: Review Figure 1 On the basis of the first embodiment, when the paper needs to be subjected to a tensile test, the movement direction of the pressing roller 27 can be changed. Specifically, a vertical plate 5 that cooperates with the reciprocating plate 28 is also installed on the horizontal frame 1, and a rectangular groove that cooperates with the horizontal connecting rod 29 is opened on the vertical plate 5.

[0074] The two ends of the horizontal connecting rod 29 are slidably arranged on the vertical frame 21 on the corresponding side. When working, the horizontal connecting rod 29 is lifted for a distance so that the horizontal connecting rod 29 will not collide with the vertical frame 21 during the rotation process. After the horizontal connecting rod 29 moves a distance, the horizontal connecting rod 29 is rotated so that the horizontal connecting rod 29 is separated from the vertical frame 21 and rotated 90 degrees. Then the horizontal connecting rod 29 is inserted into the rectangular groove. Finally, the pressing roller 27 is close to the paper, and an electronic pressure gauge is placed between the paper and the pressing roller 27 (it is a prior art and is not shown in the figure). At this time, the electronic pressure gauge is fixedly connected to the pressing roller 27, that is, the electronic pressure gauge will not It falls off from between the pressing roller 27 and the paper. During this process, the pressing roller 27 is always located between the two vertical sections of the profile frame 43, and will not collide with the profile frame 43 during the rising process of the pressing roller 27. After the horizontal connecting rod 29 is inserted into the rectangular groove, the gear 212 and the rack plate 20 are re-engaged at this time, and the servo motor drives the gear 212 to rotate through the linkage shaft 211. The gear 212 cooperates with the rack plate 20 to make the reciprocating plate 28 have a tendency to move downward, and then the reciprocating plate 28 drives the pressing roller 27 to apply external force to the paper. When the paper breaks, the reading of the electronic pressure gauge is the maximum tensile strength of the paper and is recorded.

[0075] Then, the paper can be pressed and flattened by the pressing roller 27 on the pre-processing mechanism 2, and the moving direction of the pressing roller 27 can be changed to perform tensile testing on the paper. At the same time, the subsequent flatness test results of the pre-processed paper are more accurate. The integration of paper flattening, pressing, tensile testing and flatness testing can be achieved through the pre-processing mechanism 2 and the flatness detection mechanism 3, with a higher degree of integration.

[0076] Finally, refer to Figure 10The present invention also provides an integrated intelligent paper tube base paper detection method, which includes the following steps: S1: Prepare for processing, wrap the paper around the winding roller close to the pre-processing mechanism 2, then pass the paper over the leveling roller 31 and under the coating roller 32 in sequence, and finally wrap the paper around the winding roller away from the pre-processing mechanism 2.

[0077] S2: Flatness detection. When applying the colorless phenolphthalein solution, the colorless phenolphthalein solution is immersed into the annular sponge through the discharge port inside the storage box 331. When the paper passes through the thicker annular sponge, the surface of the paper is fully in contact with the annular sponge, and the colorless phenolphthalein solution is smeared on the surface of the paper. The paper smeared with the colorless phenolphthalein solution continues to move. When the paper moves to the coating roller 32 corresponding to the alkaline solution, the alkaline solution is immersed into the annular sponge through the discharge port to apply the alkaline solution to the paper. The coating is applied to the paper by the coating roller 32, and then the paper after coating is photographed by the camera 34 to perform flatness detection on the paper.

[0078] S3: tensile test, the paper is tested for tensile strength by moving the pressing roller 27 up and down, and the reading of the electronic pressure gauge is read.

[0079] S4: Data processing, analyzing the color distribution captured by the camera 34 through an image recognition algorithm, calculating the surface flatness parameters of the paper, and determining the maximum tension value when the paper breaks through the electronic pressure gauge data curve.
