TECHNICAL FIELD
[0001] The present application relates to the technical field of moisture-proof aluminum film cloth detection, and particularly relates to a waterproof performance detection system and process for novel moisture-proof aluminum film cloth production. BACKGROUND
[0002] The novel moisture-proof aluminum film cloth is a new generation of moisture-proof and waterproof material developed on the basis of traditional aluminum film cloth through material innovation and process upgrading. It is mainly composed of ultra-thin high-purity aluminum film and high-strength polyester fiber. This combination not only keeps the material light and thin, but also improves the flatness of the aluminum film layer and the overall tensile strength. As a core technical parameter of the novel moisture-proof aluminum film cloth, the waterproof performance detection is crucial. Through waterproof performance detection, it can be verified whether the product meets the design standard, thereby ensuring its reliability in various application scenarios. In terms of detection system, the fabric water permeability tester is suitable for the detection of relatively light and thin moisture-proof aluminum film cloth. It detects the water resistance of the material by means of small water pressure, which can avoid damage caused by high pressure due to the material being too thin. The fabric water permeability tester adopts manual operation of the clamp, and uses the cooperation of the upper and lower stainless steel rings to fix the sample. The specific operation process is as follows: first, place the aluminum film cloth sample on the rubber ring of the lower stainless steel ring, and then control the upper stainless steel ring to descend by the operator, so that the rubber ring is deformed under pressure, and the sealing of the aluminum film cloth sample and the clamp is realized.
[0003] However, this operation has the following defects: since the pressing part of the clamp is the sealing part of the sample, and the aluminum film layer is brittle and has limited ductility, when the pressing force is too large, the aluminum film cloth will deform greatly with the rubber ring, and the aluminum film layer at the sealing part will wrinkle or even break due to local stress concentration. At the same time, the local deformation of the test part caused by stretching will easily cause the aluminum film layer to break. The existence of this problem will cause the novel moisture-proof aluminum film cloth to penetrate water droplets during waterproof performance testing, thereby affecting the judgment of the waterproof performance of the novel moisture-proof aluminum film cloth.

DETAILED DESCRIPTION
[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0022] Example 1, reference Figures 1-4 , for the first embodiment of the present application, a new type of moisture-proof aluminum film cloth production waterproof performance detection system is provided, including fabric water permeability tester main body 1 and lifting frame 2, also including base 3 and pressing ring 4, base 3 is fixedly sleeved on the outer wall of the fixed ring of fabric water permeability tester main body 1, support frame 5 is connected between pressing ring 4 and lifting frame 2, abutting slope 6 is formed on the top surface outside of base 3, pressing ring 4 cooperates with abutting slope 6 to fix aluminum film cloth sample, annular pressurized air bag 9 is arranged on the outer wall of base 3, annular pressing air bag 10 is arranged on the inner side of the top surface of base 3, and gas conveying channel 11 is formed in base 3, gas conveying channel 11 is in communication with annular pressurized air bag 9 and annular pressing air bag 10, annular pressurized air bag 9 is compressed when support frame 5 descends, annular pressing air bag 10 expands to abut aluminum film cloth to realize sealing; gas conveying channel 11 includes annular air groove 111 formed on the outer wall of base 3, and gas conveying hole formed on base 3, gas conveying hole is composed of Y-shaped air hole 112 and L-shaped air hole 113, two ends of L-shaped air hole 113 are in communication with Y-shaped air hole 112 and annular air groove 111 respectively, one end of Y-shaped air hole 112 is arranged on the top surface of base 3 and is in communication with annular pressing air bag 10, and the other end is arranged on the inner wall of base 3.
[0023] Specifically, when the lifting frame 2 drives the support frame 5 to descend, the pressing ring 4 will first cooperate with the abutting inclined surface 6 to form a pressing and fixing on the aluminum film cloth, and at the same time, the support frame 5 drives the annular pressurizing air bag 9 to compress, and the gas in the annular pressurizing air bag 9 flows into the annular pressing air bag 10 through the gas conveying channel 11, so as to make the annular pressing air bag 10 expand and abut against the aluminum film cloth, thereby forming a sealing surface. The separate arrangement of the fixing part and the sealing part can effectively avoid the damage of the aluminum film layer caused by the fixing part, thereby affecting the waterproof performance detection. Moreover, the flexible contact between the annular pressing air bag 10 and the aluminum film cloth can realize the sealing and water spilling prevention, and prevent the aluminum film cloth from being deformed due to excessive pulling. During the process that the annular pressurizing air bag 9 delivers the gas to the gas conveying channel 11, part of the gas will be sprayed out through the port of the Y-shaped gas hole 112 towards the inner wall of the base 3, forming a low-pressure gas flow. The gas flow can make the aluminum film cloth naturally expand, and at the same time, make the test surface protrude upward, thereby reserving enough deformation space for the annular pressing air bag 10. By separating the fixing part and the sealing part, the problem that the aluminum film layer is damaged due to the fixing operation in the traditional detection, thereby affecting the detection result, is completely solved, thereby ensuring the accuracy of the waterproof performance detection. In addition, the airflow pre-adjusting mechanism reserves deformation space for the sealing part, thereby further improving the stability and reliability of the detection process.
[0024] With reference to Figure 3 The outer wall of the base 3 is annularly and equidistantly screwed with a plurality of bolts, one end of the bolt abuts against the outer wall of the fixed ring of the fabric water permeability tester main body 1.
[0025] Specifically, the end of the bolt screwed on the base 3 tightly abuts against the outer wall of the fixed ring, and the stable connection between the base 3 and the fixed ring is realized by the fastening force of the bolt. At the same time, the rubber ring on the top surface of the fixed ring tightly abuts against the base 3, and the slight gap between the two is filled by the elastic deformation of the rubber ring, thereby forming a reliable sealing structure, and ensuring that the base 3 and the fixed ring are well sealed and connected.
[0026] It should be noted that the inner diameter of the base 3 is the same as the inner diameter of the fixed ring, thereby ensuring that the contact surface between the sample and the water will not change, and the water pressure value of the final test is consistent with the truth.
[0027] With reference to Figure 2 , Figure 7 The cross section of the pressing ring 4 is a triangular structure, the inclined surface of the pressing ring 4 is arranged towards the abutting inclined surface 6, and a plurality of anti-disengagement blocks 7 are annularly and equidistantly arranged on the inclined surface of the pressing ring 4. The anti-disengagement blocks 7 are conical structures, and the abutting inclined surface 6 is provided with anti-disengagement grooves 8 matched with the anti-disengagement blocks 7.
[0028] Specifically, when the pressing ring 4 is lowered, the inclined surface thereof cooperates with the abutting inclined surface 6 to abut and fix the edge of the aluminum film cloth. In this process, the anti-falling block 7 in the conical structure is precisely engaged with the matched anti-falling groove 8, which not only effectively eliminates the wrinkles of the aluminum film cloth on the abutting inclined surface 6, but also increases the contact area with the aluminum film cloth, thereby improving the fixing effect on the aluminum film cloth.
[0029] With reference to Figure 4 The outer wall of the base 3 is fixedly connected with a fixed ring 12 at the lower part, and the annular pressurized air bag 9 is fixedly installed on the top surface of the fixed ring 12. A plurality of air guide holes 13 are formed in the fixed ring 12, and the two ends of the air guide holes 13 are respectively communicated with the annular pressurized air bag 9 and the annular air groove 111. An annular plate 14 is arranged on the top surface of the annular pressurized air bag 9.
[0030] Specifically, when the support frame 5 is lowered, it is in contact with the annular plate 14 and drives the annular pressurized air bag 9 to be compressed. The gas in the annular pressurized air bag 9 sequentially passes through the air guide holes 13, the annular air groove 111, the L-shaped air hole 113, and flows out through the other two ports of the Y-shaped air hole 112. A part of the gas blows the aluminum film cloth towards the port on one side of the inner wall of the base 3 through the Y-shaped air hole 112, so as to make it relax, and the other part of the gas flows into the annular pressurized air bag 10 through the port on the top surface of the base 3, so as to make it expand and contact with the aluminum film cloth to realize waterproof sealing.
[0031] Embodiment 2, with reference to Figure 4 、 Figure 5 This is the second embodiment of the present application, which is different from the first embodiment in that: the diameter of the Y-shaped air hole 112 is greater than that of the L-shaped air hole 113, a gas delivery control 15 is slidably arranged in the inclined part of the Y-shaped air hole 112, and a one-way valve 16 is arranged at one end of the Y-shaped air hole 112 towards the inner wall of the base 3. The gas delivery control 15 and the one-way valve 16 cooperate to control the moving direction of the gas flow; the gas delivery control 15 comprises a cylindrical slide column 151, a fan-shaped hole 152 is formed in the slide column 151, a sealing plate 153 is slidably connected to one end of the slide column 151 towards the one-way valve 16, the fan-shaped hole 152 and the sealing plate 153 are arranged in an up-and-down staggered manner, and an elastic member one is connected between the sealing plate 153 and the slide column 151.
[0032] Specifically, the one-way valve 16 is used to control the one-way outflow of the gas in the Y-shaped gas hole 112 to the inside of the base 3. The gas regulating component 15 is located at the lowermost end of the Y-shaped gas hole 112 in the natural state, and the slide column 151 blocks the upper gas hole of the Y-shaped gas hole 112. When the gas flows into the Y-shaped gas hole 112 from the L-shaped gas hole 113, the gas flows into the one-way valve 16 through the fan-shaped hole 152 and is discharged into the base 3 through the one-way valve 16, and at the same time, the slide column 151 slides upward along the inclined gas hole of the Y-shaped gas hole 112. When the sealing plate 153 abuts against the one-way valve 16, the inlet hole of the one-way valve 16 is closed, and at the same time, the slide column 151 unblocks the upper part of the Y-shaped gas hole 112. At this time, the gas enters the annular pressure-resistant air bag 10.
[0033] Through the cooperation of the gas regulating component 15 and the one-way valve 16, the orderly switching of the gas flow direction is realized. First, the gas flow is used to fully stretch the aluminum film cloth, and then the annular pressure-resistant air bag 10 is inflated to form a seal. This not only ensures the flatness of the test surface of the aluminum film cloth, but also ensures the timeliness and reliability of the seal, and further improves the accuracy of the waterproof performance detection.
[0034] It should be noted that the flow area of the fan-shaped hole 152 is smaller than that of the L-shaped gas hole 113, so when the L-shaped gas hole 113 continuously delivers gas to the Y-shaped gas hole 112, the slide column 151 is driven to slide upward under the action of the gas flow.
[0035] Referring to Figure 6 The one-way valve 16 includes a gas pipe 161 fixedly installed on the inner wall of the Y-shaped gas hole 112. The gas pipe 161 has a convex structure, both ends of the gas pipe 161 are threadedly connected with sealing covers 162, the gas pipe 161 is abutted and matched with a sealing block 163 in a circular truncated cone structure, an inlet hole is formed in the sealing cover 162 facing the sealing plate 153, and the other sealing cover 162 and the sealing block 163 are jointly connected with an elastic member two; the small end of the gas pipe 161 is arranged towards the inner wall of the base 3, and a plurality of outlet holes are formed in the small end of the gas pipe 161.
[0036] Specifically, under the action of the elastic member two, the sealing block 163 will be in close abutment with the gas pipe 161, so as to realize the one-way flow of the gas, and also effectively prevent the water in the base 3 from flowing into the gas delivery channel 11. When the gas enters the gas pipe 161 through the inlet hole, the gas pressure at the left end of the gas pipe 161 will gradually increase. When the gas pressure exceeds the elastic force of the elastic member two, the sealing block 163 will move to the side of the elastic member two, and the gas can be discharged through the outlet hole. When the sealing plate 153 moves to abut against the inlet hole, the one-way valve 16 stops the gas flow. At this time, the flow direction of the gas will be changed to flow from the vertical gas hole of the Y-shaped gas hole 112.
[0037] The one-way flow control ensures that the gas is transported along the preset path, avoids the influence of airflow turbulence on the stretching of the aluminum film cloth and the inflation of the annular abutting air bag, effectively prevents the backflow of water in the base 3 into the gas conveying channel 11, avoids affecting the water pressure value, guarantees the normal operation of the gas conveying system, and accurately realizes the switching of the gas flow direction through cooperation with the sealing plate 153, further improving the stability and accuracy of the detection process.
[0038] The one-way flow control ensures that the gas is transported along the preset path, avoids the influence of airflow turbulence on the stretching of the aluminum film cloth and the inflation of the annular abutting air bag, effectively prevents the backflow of water in the base 3 into the gas conveying channel 11, avoids affecting the water pressure value, guarantees the normal operation of the gas conveying system, and accurately realizes the switching of the gas flow direction through cooperation with the sealing plate 153, further improving the stability and accuracy of the detection process.
[0039] Embodiment 3, referring to Figure 1 、 Figure 7 , is a third embodiment of the present application, which is different from the second embodiment in that the support frame 5 comprises a plurality of annularly and equidistantly arranged support rods 51, the support rods 51 are arranged obliquely, the upper end of the support rod 51 is fixedly installed on the lifting frame 2, the lower end of the support rod 51 is fixedly connected with a sliding rod 52, the sliding rod 52 is slidingly connected with the pressing ring 4, and the lower end of the support rod 51 and the pressing ring 4 are jointly connected with an elastic member three.
[0040] Specifically, when the lifting frame 2 is manually operated to drive the support frame 5 to descend, the annularly and equidistantly arranged obliquely arranged support rods 51 will move downward, and the sliding rod 52 connected with the lower end of the support rod 51 will also drive the pressing ring 4 to move downward synchronously. Since the sliding rod 52 and the pressing ring 4 are slidingly connected, and the elastic member three is connected between the lower end of the support rod 51 and the pressing ring 4, after the pressing ring 4 contacts the aluminum film cloth, the elastic member three will elastically deform, and the pressing ring 4 will form elastic abutment on the aluminum film cloth by means of the elastic force of the elastic member three. The elastic abutment mode can avoid the pressing ring 4 exerting excessive rigid force on the aluminum film cloth, and prevent the aluminum film layer from being damaged due to excessive force.
[0041] Referring to Figure 8 、 Figure 9 , the lower part of the sliding rod 52 is provided with a through hole, an L-shaped rod 17 is hinged in the through hole, an arc surface 18 is formed in the upper end of the L-shaped rod 17, the arc surface 18 is abutted and matched with the bottom surface of the pressing ring 4, and a fixed plate 19 is fixedly connected with the position of the outer wall of the base 3 corresponding to the L-shaped rod 17.
[0042] Specifically, when the arc surface 18 abuts against the pressing ring 4, the elastic member three is in a compressed and stored state. Due to the action of the gravity of the lower part of the L-shaped rod 17, the arc surface 18 will protrude outward of the sliding rod 52, thereby limiting the downward sliding of the pressing ring 4. When the lower end of the L-shaped rod 17 contacts the fixed plate 19, the L-shaped rod 17 will rotate around the hinge point, the arc surface 18 will retract into the sliding rod 52, and the limiting action on the pressing ring 4 is released at this time. The elastic member three releases the elastic force, drives the pressing ring 4 to rapidly descend, and realizes the abutment and fixation of the aluminum film cloth.
[0043] Wherein, the circle formed by the diameter from the rotating axis of the L-shaped rod 17 to the arc surface 18 coincides with the arc surface 18, when the L-shaped rod 17 rotates, the arc surface 18 contacts the pressing ring 4 and keeps the pressing ring 4 and the sliding rod 52 relatively stationary.
[0044] Need to be explained, the personnel in the operation of the lifting frame 2 need to keep the support frame 5 keep uniform speed down, when the sliding rod 52 drives the ring plate 14 down, the sliding column 151 slides up in the Y-shaped air hole 112, when the sealing plate 153 contacts the air inlet hole of the one-way valve 16, the L-shaped rod 17 contacts the fixed plate 19, at this time the aluminum film cloth test surface has formed an upward convex, then the pressing ring 4 down to the edge of the aluminum film cloth is fixed, and then the annular pressing air bag 10 is inflated to contact the aluminum film cloth, forming a waterproof sealing layer. The rest of the structure is the same as that of example 2.
[0045] Synthesize example 1-3, the working principle of the present application: the aluminum film cloth sample is placed on the top surface of the base 3, the lifting frame 2 is manually operated to drive the support frame 5 to uniformly descend, the support frame 5 descends to compress the annular pressurized air bag 9, the gas is first ejected through the Y-shaped air hole 112 to the port on the side of the inner wall of the base 3, forming a gas pressure airflow to blow the aluminum film cloth, making it upward convex, then the L-shaped rod 17 contacts the fixed plate 19 to cancel the limiting of the pressing ring 4, the pressing ring 4 descends to cooperate with the abutting inclined surface 6 to abut and fix the edge of the aluminum film cloth, at the same time, the sliding column 151 slides upward to the sealing plate 153 to abut the one-way valve 16, the gas flows through the Y-shaped air hole 112 to the annular pressing air bag 10, the annular pressing air bag 10 inflates and contacts the aluminum film cloth to form a waterproof sealing layer.
[0046] The main body 1 of the fabric water permeability tester is filled with water into the base 3, and the water is continuously and slowly increased to complete the waterproof performance detection of the aluminum film cloth.
[0047] Example 4, refer to Figures 1-9 , the fourth embodiment of the present application, provides: a new type of moisture-proof aluminum film cloth waterproof performance detection process, comprising the following steps: S1, sample pretreatment: randomly cut at least 3 samples from the new type of moisture-proof aluminum film cloth, each size is larger than the size of the pressing ring 4, to ensure that the sample is free of wrinkles, damage or stains; S2, sample fixing: place a sample aluminum film surface down on the base 3, the personnel operate the lifting frame 2 to drive the pressing ring 4 to descend to abut and fix the sample, the annular pressurized air bag 9 drives the annular pressing air bag 10 to inflate, so that the annular pressing air bag 10 and the contact surface between the sample form a seal; S3, pressurized detection: fill water into the base 3, after the water contacts the test surface of the sample, continuously and slowly pressurize, observe the water seepage condition of the sample surface, record the water pressure value when three water droplets seep out of the sample surface, and stop pressurizing; S4, continuous testing: the personnel operates the lifting frame 2 to drive the pressing ring 4 to rise, removes the current sample and replaces a new sample, and sequentially completes the waterproof performance detection of all samples according to the steps S1-S3.
