DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figure 1 to Figure 7 As shown, it is the first embodiment of the present invention, which provides a waterproof coiled material detection device, including a frame 100 and a driving structure 400, wherein a winding structure 200 and an unwinding structure (not shown) are arranged in the frame 100, the driving structure 400 drives the winding structure 200 to wind, and the coiled material is tensioned in the winding structure 200 and the unwinding structure, and further includes a detection structure 500 and a tensioning structure 600;

[0043] The detection structure 500 includes two groups of detection units, each group of detection units includes an extrusion structure 510 and a coating structure 520. The extrusion structure 510 stores the detection liquid and squeezes the detection liquid into the coating structure 520. The coil is pressed on the surface of the coating structure 520. The coating structure 520 is driven to rotate during the transportation of the coil, so that the detection liquid is coated on the surface of the coil.

[0044] Among them, the detection agent is configured as a color developer and a decolorizer that do not react with the coil, and the color developer and the decolorizer neutralize the discoloration; the two groups of extrusion structures 510 are respectively loaded with the color developer and the decolorizer, and the color developer and the decolorizer are successively applied to the same surface of the coil through the coating structure 520.

[0045] Specifically, a plurality of guide structures 300 are provided in the frame 100. The coiled material in a tensioned state is transported into the frame 100. The guide structures 300 fix the moving trajectory of the waterproof coiled material so that the coiled material is pressed against the upper surface of the coating structure 520. Secondly, the guide structures 300 change the moving trajectory of the coiled material, extend the transportation time of the coiled material from the unwinding structure to the winding structure 200, extend the reaction time of the color developer and the color remover, and facilitate the drying of the color developer and the color remover.

[0046] During the damage detection process of the waterproofing membrane, the waterproofing membrane is pressed against the surface of the coating structure 520, and the coating structure 520 successively coats the developer and the decolorizer on the surface of the waterproofing membrane. The developer and the decolorizer achieve color change through chemical reactions with each other without reacting with the waterproofing membrane. After the developer is coated on the surface of the waterproofing membrane, the surface of the waterproofing membrane will present a specific color. Subsequently, when the decolorizer is coated on the same surface, the color of the normal area will be neutralized by the decolorizer and restored to its original state.

[0047] Among them, the selection of color developer and decolorizer needs to be determined according to the material of the waterproof membrane to ensure that the color developer and decolorizer will not produce chemical reactions with the waterproof membrane. At the same time, the diffusion abilities of the color developer and decolorizer are inconsistent, so that the color developer passes through the damaged area of ​​the waterproof membrane to enter the reverse area of ​​the waterproof membrane that is not coated with the color developer and then diffuses. The resulting diffusion area is larger than the area where the decolorizer passes through the damaged area of ​​the waterproof membrane to enter the reverse area of ​​the waterproof membrane that is not coated with the color developer and diffuses. The specific models of the color developer and decolorizer are obtained by technical personnel in this field based on experiments.

[0048] First, the coiled material enters the color developer coating structure 520, the color developer is squeezed out from the extrusion structure 510, the coating structure 520 absorbs the color developer and evenly coats it on the surface of the coiled material. In the intact area of ​​the waterproof coiled material, the color developer is evenly distributed to form a consistent color; in the damaged area, due to the damage of the waterproof coiled material, the color developer diffuses through the damaged area of ​​the waterproof coiled material to the reverse area of ​​the waterproof coiled material that is not coated with the color developer. Subsequently, the waterproof coiled material enters the decolorant coating structure 520, the decolorant is squeezed out from the extrusion structure 510, and the coating structure 520 evenly coats the decolorant on the surface of the waterproof coiled material coated with the color developer. In the intact area, the decolorizer reacts with the developer to generate a colorless compound, and the color disappears; in the damaged area, since the diffusion area of ​​the decolorizer is smaller than that of the developer, the diffusion area of ​​the decolorizer cannot completely cover the diffusion area of ​​the developer, which causes part of the colored area to be unable to be decolorized, resulting in a ring-shaped dotted area, that is, a dot-shaped colored ring ring appears on the surface of the waterproof membrane, and the center of the colored ring ring is the damaged position.

[0049] The smearing structure 520 includes a quantitative box 521 and a smearing roller 527. A quantitative cavity for containing liquid is formed in the quantitative box 521, and a high liquid level line, a low liquid level line and a liquid level sensor 528 are engraved in the quantitative cavity. The liquid level sensor 528 is used to monitor the liquid level in the quantitative cavity. The extrusion structure 510 is configured to suck the test liquid so that the liquid level line in the quantitative cavity rises to the high liquid level line.

[0050] The extrusion structure 510 includes a liquid storage tank 511, a suction pump 512 and a hose 513. The suction pump 512 is located at the top of the hose 513 to extract the detection liquid in the liquid storage tank 511 into the hose 513.

[0051] The quantitative cavity penetrates the side of the quantitative box 521 to form a socket 522 , and the hose 513 is connected to the quantitative cavity through the socket 522 , so that the suction pump 512 can pour the detection liquid in the hose 513 into the quantitative cavity.

[0052] Specifically, a control system is configured in the quantitative box 521, and the control system includes a control center. The liquid level sensor 528 monitors the liquid level height in the quantitative chamber and transmits the monitored liquid level line to the control center. The control center receives the electrical signal transmitted by the liquid level sensor 528 and analyzes it to obtain the real-time liquid level in the quantitative chamber. When the monitored liquid level line is flush with the low liquid level line, a filling signal is generated, and the suction pump 512 is controlled based on the filling signal to extract liquid into the quantitative chamber so that the liquid level in the quantitative chamber reaches the high liquid level line. When the monitored liquid level line is flush with the high liquid level line, a stop signal is generated, and the suction pump 512 is controlled to stop running based on the stop signal, thereby ensuring that the liquid level line in the quantitative chamber is always between the high liquid level line and the low liquid level line.

[0053] Exemplarily, the smear roller 527 includes an inner roller 5271 rotatably installed in the quantitative box 521, and the surface of the inner roller 5271 is coated with a thickened silicone layer 5272 and a sponge layer 5273 in sequence. When the coil is conveyed, the squeezing force drives the smear roller 527 to rotate, and the outer peripheral surface of the passively rotating smear roller 527 is immersed in the detection liquid, so that the sponge layer 5273 on the surface of the smear roller 527 absorbs the detection liquid to be evenly applied to the surface of the coil;

[0054] Among them, the lowest point of the sponge layer 5273 located in the quantitative cavity is at the same height as the low liquid level line, and the lowest point of the thickened silicone layer 5272 located in the quantitative cavity is higher than the high liquid level line.

[0055] Specifically, the quantitative box 521 is located at the mounting groove 523 and extends downward to form two sets of mounting plates 5211 . The smear roller 527 is inserted into the mounting plate 5211 and rotates inside the mounting plate 5211 .

[0056] In order to prevent the smear roller 527 from shifting during the rotation process, two sets of annular rings 5274 are provided at both ends of the mounting plate 5211 , and the two sets of annular rings 5274 are fixed to the ends of the inner roller 5271 .

[0057] In addition, in order to reduce the friction between the annular ring 5274 and the mounting plate 5211, which causes the coating roller 527 to rotate unsmoothly, a plurality of balls 5275 are embedded in the end surface of the annular ring 5274 facing the mounting plate 5211, and the sliding friction between the annular ring 5274 and the inner roller 5271 is converted into rolling friction, so as to reduce the jamming and unsmoothness of the coating roller 527 during rotation.

[0058] Exemplarily, the quantitative cavity penetrates the top surface of the quantitative box 521 to form a mounting groove 523, the smear roller 527 is installed in the mounting groove 523, and two sets of fixings 526 are provided at both ends of the quantitative box 521, and the two sets of fixings 526 are inserted into the frame 100 to limit the rotation of the quantitative box 521.

[0059] A card slot 101 for inserting the quantitative box 521 is opened on the surface of the frame 100, and the fixing member 526 is engaged in the card slot 101. The coiled material in the tensioned state is caused to cover the mounting slot 523 of the quantitative box 521 through the guide structure 300. The fixing member 526 is used to limit the rotation of the quantitative box 521 so that the mounting slot 523 on the surface of the quantitative box 521 is always facing upwards, and the coiled material covers the position of the coating roller 527.

[0060] The fixing part 526 includes a ring 5261, an extension rod 5262 and a ball head 5263. The ring 5261 fixes the ball head 5263 through the extension rod 5262. The ball head 5263 is sunk into the slot 101. The ring 5261 is sleeved on both ends of the quantitative box 521. The ball head 5263 contacts the slot 101 through its smooth surface to reduce the friction between the slot 101 and the ball head 5263.

[0061] A sleeve 524 is sleeved at both ends of the quantitative box 521, and two sets of bearings 525 are pressed into the inner cavity of the sleeve 524 with high strength. The bearings 525 are connected to the two ends of the quantitative box 521 by interference fit. The inner ring of the bearing 525 is tightly sleeved on the end of the quantitative box 521 to form a whole. The fixing part 526 is fixed to the outer surface of the sleeve 524.

[0062] Working principle: First, the operator starts the system, checks the power connection and the installation of each mechanical component, ensures that all equipment is working properly, and adds an appropriate amount of developer and decolorizer to the liquid storage tank 511. After starting the control system and setting the parameters such as the speed of the coil and the coating speed, the unwinding structure is turned on, and the waterproof coil is released from the unwinding structure and smoothly enters the interior of the frame 100 along a predetermined path under the guidance of the guide structure 300. The guide structure 300 ensures that the coil will not deviate or wrinkle during the conveying process, thereby ensuring the accuracy of the detection.

[0063] When the coil is guided for the first time, it needs to be guided manually so that the coil is wound on the winding structure 200 .

[0064] The waterproofing coiled material first passes through the color developer coating structure 520. At this time, the suction pump 512 in the extrusion structure 510 is started to extract the color developer from the liquid storage tank 511 and send it to the quantitative tank 521 through the hose 513. The liquid level sensor 528 in the quantitative tank 521 continuously monitors the liquid level. When the liquid level drops to the low level line, the control system sends a signal to start the suction pump 512 to replenish the color developer until the liquid level reaches the high level line. The coating roller 527 rotates passively during the coiled material conveying process, and its surface is immersed in the color developer, and the color developer is evenly coated on the surface of the coiled material. The color developer is evenly distributed in the intact area of ​​the waterproofing coiled material to form a consistent color; in the damaged area, due to the damage of the waterproofing coiled material, the color developer will diffuse through the damaged area to the reverse area of ​​the coiled material that is not coated with the color developer, and the diffusion area is large.

[0065] Next, the coiled material coated with the developer continues to move forward and enters the decolorant coating structure 520. The working principle of the decolorant coating structure 520 is similar to that of the developer coating structure 520. The decolorant is drawn from the liquid storage tank 511 to the quantitative tank 521 by the suction pump 512, and is evenly coated on the surface of the coiled material coated with the developer by the coating roller 527. In the intact area, the decolorant and the developer react chemically to generate a colorless compound, and the color disappears; while in the damaged area, since the diffusion area of ​​the developer is larger than that of the decolorant, the decolorant cannot completely cover the diffusion area of ​​the developer, resulting in some areas still retaining color, forming annular dot areas, and the center of these color-developing annular circles is the damaged position of the waterproof coiled material.

[0066] Finally, the tested waterproofing membrane is recovered by the reeling structure 200. The operator can determine the damaged position by observing the colored ring on the surface of the membrane, thereby repairing the waterproofing membrane or removing unqualified products. The entire testing process is highly automated and can efficiently and accurately test the integrity of the waterproofing membrane to ensure product quality.

The two groups of silicone positioning rings 700 are used to limit the displacement of the coil during the conveying process to ensure the accuracy of the coating area of ​​the coating roller 527.

[0069] Example 3

[0077] Specifically, the base 1 includes a triangular plate 612 and a round rod 611 inserted in the triangular plate 612. When the output end of the cylinder 613 outputs, the sleeve follows the output end of the cylinder 613 to run, and then pushes the rotating plate 615 to rotate through the pin shaft 614, and the synchronization rod 616 fixedly connected to the rotating plate 615 and the clamping plate 617 fixedly connected to the synchronization rod 616 passively rotate, and the position of the smearing structure 520 clamped by the clamping plate 617 changes, wherein the movement trajectory of the smearing structure 520 is a linear displacement movement at the upper edge of the frame 100.

[0078] Exemplarily, the second clamping structure includes a second clamping plate 625 and a second pin 624 fixed to the surface of the second clamping plate 625 , and the second angle driving structure rotates on the surface of the second pin 624 to push the second clamping plate 625 to rotate through the second pin 624 .

[0079] Angle drive structure 2 includes cylinder 2 621, shaft sleeve 2 and base 2. Cylinder 2 621 is fixed to the surface of frame 100 through base 2. Shaft sleeve 2 is sleeved on the surface of pin shaft 2 624 to drive shaft sleeve 2 to move through the output end of cylinder 2 621 to pull or push clamping plate 2 625 to change its position.

[0080] Specifically, base two includes a triangular plate two 622 and a round rod two 623 inserted in the triangular plate two 622. When the output end of the cylinder two 621 outputs, the sleeve two follows the output end of the cylinder two 621 to run, and then pushes the clamping plate two 625 to rotate through the pin shaft two 624, and the position of the coating structure 520 clamped by the clamping plate two 625 changes, wherein the motion trajectory of the coating structure 520 is a linear displacement motion at the upper edge of the frame 100.

[0081] Among them, the output end of the second cylinder 621 drives the second sleeve to move, so as to pull or push the second clamping plate 625 to change its position, and the second clamping plate 625 transmits the reaction force to the second cylinder 621 through the second sleeve, so that the second cylinder 621 rotates with the center line of the second round rod 623 as the center of the circle through the second triangle plate 622.

[0082] The output end of the cylinder 613 drives the sleeve 1 to move, so as to pull or push the clamping plate 1 617 to change its position, and the clamping plate 1 617 transmits a reaction force to the cylinder 1 613 through the sleeve 1, so that the cylinder 1 613 rotates with the center line of the round rod 1 611 as the center through the triangular plate 1 612.

[0083] When the position of the coating structure 520 remains unchanged, the coiled material squeezes the coating roller 527 during transportation so that the detection liquid on the surface of the coating roller 527 is coated on the surface of the coiled material. The damaged position is determined by referring to the position of the colored ring on the surface of the coiled material, thereby repairing the waterproof coiled material or eliminating unqualified products.

[0084] When the clamping structure is driven to move by the angle driving structure, the movement trajectory of the coil can be changed, thereby lengthening or shortening the required coil length from the unwinding structure to the winding structure 200. When the unwinding structure to the winding structure 200 is not equipped with an adaptive tension device, a sensor for sensing the coil in a tensioned state can be installed on the surface of the guide structure 300 to finely adjust the angle of the clamping structure, and then finely adjust the position of the coating structure 520 to adaptively adjust the tension of the coil.

[0085] In addition, for areas that require fine measurement, or for cases where the thickness of the coil is relatively thick or the damaged area on the surface of the coil is too small, the portion of the coil that needs to be measured is placed between the angle driving structure 1 and the angle driving structure 2, and the angle driving structure 1 and the angle driving structure 2 can respectively drive the clamping structure 1 and the clamping structure 2 at the same time. The clamping structure 1 and the clamping structure 2 synchronously drive the two groups of coating structures 52 to swing back and forth, and the reciprocatingly swinging coating structure 520 repeatedly applies the color developer and the decolorizer on the surface of the coil in an alternating manner to ensure that the color developer and the decolorizer can penetrate to the back of the coil.

[0086] A detection method applied to a waterproof coiled material detection device, comprising the following steps:

[0087] S1: The operator starts the system, checks the power connection and the installation of each mechanical component, ensures that all equipment is working properly and sets the parameters; adds an appropriate amount of developer and decolorizer to the liquid storage tank 511; opens the unwinding structure, and the waterproofing roll is released from the unwinding structure. When guiding for the first time, it is necessary to manually guide the roll to be wound on the winding structure 200;

[0088] S2: The waterproofing coiled material is guided by the guide structure 300 and smoothly enters the interior of the frame 100 along a predetermined path. The coiled material first passes through the developer coating structure 520. The suction pump 512 in the extrusion structure 510 extracts the developer from the liquid storage tank 511 and sends it to the quantitative tank 521 through the hose 513. The coating roller 527 passively rotates during the coiled material conveying process, and its surface is immersed in the developer, and the developer is evenly coated on the surface of the coiled material;

[0089] S3: The web coated with the developer continues to move forward and enters the decolorant coating structure 520. The decolorant is drawn from the liquid storage tank 511 to the quantitative tank 521 by the suction pump 512, and is evenly coated on the surface of the web coated with the developer by the coating roller 527. In the intact area of ​​the web, the decolorant and the developer react chemically, and the color disappears; while in the damaged area, since the diffusion area of ​​the developer is larger than the diffusion area of ​​the decolorant, the decolorant cannot completely cover the diffusion area of ​​the developer, resulting in some areas still retaining color, forming a ring-shaped dot area.

[0090] Beneficial effects: The waterproof coiled material detection device includes a frame 100, a winding structure 200, an unwinding structure, a detection structure 500 and a tensioning structure 600. The detection structure 500 includes two groups of detection units, each of which includes an extrusion structure 510 and a coating structure 520. The extrusion structure 510 stores the detection liquid and squeezes it into the coating structure 520. During the conveying process, the coiled material is pressed on the surface of the coating structure 520, driving the coating structure 520 to rotate, so that the detection liquid is evenly coated on the surface of the coiled material. The color change is achieved through the chemical reaction of the detection liquid, and the damaged position of the coiled material is detected by the color difference of the damaged area, without marking it. The entire waterproof coiled material detection device has a simple structure and is easy to operate.

[0091] A plurality of guide structures 300 are arranged in the frame 100, and two sets of silicone positioning rings 700 are arranged on the surface of each guide structure 300 to ensure the accurate position of the coil during the conveying process and avoid deviation or wrinkles. The guide structure 300 also changes the running track of the coil, prolongs the conveying time of the coil from the unwinding structure to the winding structure 200, prolongs the reaction time of the color developer and the decolorizer, and facilitates the drying of the detection liquid.

[0092] The tensioning structure 600 includes two sets of tensioning units, each of which includes a clamping structure and an angle driving structure. The clamping structure is used to clamp the coating structure 520, and the angle driving structure drives the sleeve to move through the cylinder, pushing the clamping plate to rotate, changing the position of the coating structure 520, changing the tension of the coil, and also being applicable to coils of different thicknesses and degrees of damage. This not only improves the flexibility and reliability of detection, but also can finely adjust the motion trajectory of the coil to ensure the accuracy of detection.

[0093] The entire detection process is highly automated, from unwinding the coil, applying the developer and decolorizer to rewinding, without manual intervention, which improves production efficiency and detection speed. The combination of the silicone positioning ring 700 and the tensioning structure 600 ensures the accurate position of the coil during transportation, avoids deviation, and improves detection accuracy. The device is suitable for waterproof coils of different types and thicknesses, has a wide range of applicability and efficient detection capabilities, and can effectively improve the quality control level of waterproof coils.
