Description

TECHNICAL FIELD

[0002] In actual cloth manufacturing work, water permeability detection work related to cloth is needed, and a static pressure tester is needed to stably test the pressure of the cloth. Common environment-friendly water-based waterproof coatings include acrylic waterproof coatings, etc. The anti-permeability of the coating is evaluated by continuously increasing the water pressure. The weight of the seepage water is detected after the seepage water is absorbed by the blotting paper. The current static pressure tester for cloth testing mainly presses the cloth for subsequent pressure testing through clamping. The cloth will swell after being pressed, and the fibers near the lower pressing ring of the static pressure tester are easily damaged due to local pressure, resulting in a higher leakage rate, which can affect the accuracy of the water permeability test of the cloth. It is not convenient to automatically sample the core. At the same time, water is easily attached to the surface of the cloth after the test is completed, which can interfere with the subsequent test. Manual wiping is usually required, which is not convenient for automatic control of sample area qualification. If the sample area is too small, it can affect the clamping stability and is not convenient for preventing operators from testing irregularly.

[0003] Therefore, we propose a testing device and testing method for manufacturing environment-friendly water-based coated cloth. SUMMARY

The suction pump 401 is located inside the test shell 101. The suction pump 401 is connected with the control valve 402 through a hose.

[0040] The core sampling piece 5 comprises a sampling rubber pad 501 and an outer ring water absorption sponge 502. The sampling rubber pad 501 is fixedly installed in the inner ring of the pressing ring frame 303. The outer ring of the sampling rubber pad 501 is pasted with the outer ring water absorption sponge 502 through glue liquid, and the outer ring water absorption sponge 502 is located on the inner side of the pressing ring frame 303. The outer ring water absorption sponge 502 is used to absorb the seepage water close to the pressing ring frame 303. The core sampling piece 5 further comprises a suction pipe 503 and a water absorption paper 504. The suction pipe 503 is fixedly installed on the sampling rubber pad 501. The suction pipe 503 is communicated with the inner side of the sampling rubber pad 501. The end of the suction pipe 503 is connected to the hose of the control valve 402. The bottom of the sampling rubber pad 501 is pasted with the water absorption paper 504 through glue liquid, and the diameter of the water absorption paper 504 is smaller than that of the outer ring water absorption sponge 502. The support ring 404 is aligned with the bottom of the sampling rubber pad 501. The core sampling piece 5 can be used for the anti-permeation test of the cloth. Only the core of the cloth is used for sampling the seepage water. The cloth close to the pressing ring frame 303 is isolated and distinguished, and is directly excluded. The test precision of the structure can be improved. Since the sample cloth is inflated upward under the action of water pressure, it is subjected to the pressure action of the inner ring edge of the pressing ring frame 303, and is more likely to be damaged, and then seepage occurs in the test process. This part of the seepage is not caused by the cloth itself. The structure is used for the middle sampling method. The cloth in the middle is more evenly pressed, and the data is more accurate. At the same time, the structure can utilize negative pressure. When the cloth is taken down, it can be sucked back to prevent water on the cloth from dripping, and further ensure the accuracy in subsequent quality detection. When the cloth is inflated under the action of water pressure, the water absorption paper 504 can be attached to the surface of the cloth in the middle. The sampling rubber pad 501 itself is a rubber elastic structure. The edge of the bottom is attached to the surface of the cloth to assist in isolation. When the cloth close to the inner ring of the pressing ring frame 303 leaks, the outer ring water absorption sponge 502 can absorb it, and the water can be drained through the drain pipe 3031.

[0041] In Example 2, based on Example 1, the flat marking component 6 includes: a clamping shell 601, a grounding strip 6011, a clamping spring 602, and clamping tips 603. The clamping shell 601 is fixedly installed on the test shell 101; the grounding strip 6011 is fixedly embedded in the clamping shell 601; the clamping spring 602 is fixedly installed on the bottom inner side of the clamping shell 601; the end of the clamping spring 602 elastically fits onto the grounding strip 6011; a row of clamping tips 603 is fixedly installed on the side of the clamping spring 602; the clamping tips 603 are used to clamp the fabric; the grounding strip 6011, the clamping spring 602, and the positioning electromagnet 103 are electrically connected. Using the flat marking component 6 makes it easier for workers to mark the pressure test surface of the fabric, especially for double-sided waterproof fabrics requiring double-sided testing. By first clamping the fabric, it is easier to quickly control the flipping after testing. This avoids confusion caused by the similarity of the front and back sides of the double-sided waterproof fabric when manually removing the fabric for data recording, which can lead to test confusion and require retesting. The flat marking piece 6 ensures that the fabric can only be tested when it is positioned, improving the standardization of the operation and preventing staff from forgetting to do so. After the fabric test is completed, the fabric can be removed from the flat marking piece 6 to test the other side, ensuring that the fabric is clamped and positioned before flipping. This prevents confusion during the flipping process. The clamping spring piece 602 also facilitates the flat clamping of the fabric, making it easy to lay it flat on the water pressure plate 201.

[0042] A test method for manufacturing environmentally friendly water-based coated fabrics:

[0043] 1) The end of the fabric is clamped by the clamping spring 602 and positioned against the fabric by the clamping tip 603. At this time, the clamping spring 602 and the electrical strip 6011 are separated by the fabric.

[0044] 2) Place the fabric in the rubber gasket 204, rotate the pressing screw 301 to push the pressing cylinder 302 to drive the bottom of the pressing ring 303 to squeeze and adhere to the fabric, control the water pressure pump 202 to start water supply and apply water pressure to the fabric.

[0045] 3) When there is a leak in the fabric near the inner ring of the lower pressure ring 303, drain it through the drain pipe 3031. After the pressure is applied, control the lower pressure ring 303 to rise and peel the absorbent paper 504 off the sampling rubber pad 501 for weighing.

[0046] The working principle of the embodiment is as follows: first, the end of the cloth is clamped through the clamping spring 602, and the clamping sharp block 603 plays a positioning role. At this time, the clamping spring 602 and the power connection strip 6011 are separated by the cloth. The cloth is placed on the water pressure disc 201, and the area of the cloth needs to cover a circle of isolation springs 203, so that the subsequent rotating down pressure screw 301 pushes the down pressure cylinder 302 to drive the bottom of the down pressure ring frame 303 to extrude and fit on the cloth, until the cloth is completely fastened. At this time, the isolation spring 203 and the power connection ring 304 are separated by the cloth, and cannot be powered on. The electromagnetic valve 2021 remains open, and the water supply and water pressure adjustment of the water pressure pump 202 can be normally supplied. The water is discharged from the water pressure disc 201 to apply water pressure to the cloth to test the leakage resistance of the cloth. If the cloth selection width is not up to standard or the placement position is not up to standard, and a circle of isolation springs 203 cannot be completely covered, a circle of isolation springs 203 will not be separated, and the local isolation spring 203 can be fitted to the power connection ring 304 to realize power connection. At this time, the electromagnetic valve 2021 can be powered off, and the worker cannot normally control the water supply of the water pressure pump 202, and needs to be adjusted in time. When the down pressure screw 301 pushes the down pressure cylinder 302 to move downward, the bottom of the down pressure ring frame 303 extrudes and fits on the cloth, and the down pressure screw 301 can be further rotated to extrude the leakage prevention spring 3011 until the leakage prevention spring 3011 is completely compressed, and the disconnect switch 3012 is driven to extrude and fit on the down pressure cylinder 302. When the test is completed, the water pressure pump 202 is turned off, and the down pressure screw 301 is reversed to loosen. When the down pressure screw 301 moves upward, the leakage prevention spring 3011 will further press the down pressure ring frame 303 to elastically fit the cloth. At this time, the disconnect switch 3012 is no longer extruded, and the control valve 402 on the suction pump 401 can be quickly controlled to open, and the suction ring 403 can quickly suck the residual water at the bottom of the cloth. Thanks to the extrusion of the leakage prevention spring 3011 at this time, the down pressure ring frame 303 is still elastically fitted to the cloth, and the cloth can be directly pulled and sucked by the sliding suction ring 403 fitted to the bottom of the cloth. The down pressure screw 301 is continuously rotated to drive the down pressure ring frame 303 away from the cloth. When the next test is needed, the suction ring 403 can keep sucking, and the water pressure pump 202 is opened to fill the rubber gasket 204 above the water pressure disc 201. Once the rubber gasket 204 overflows, the suction ring 403 can suck the water back through the suction pump 401 and discharge it into the test shell 101 for recycling.When the cloth is inflated under the action of water pressure, the water absorption paper 504 can be attached to the surface of the middle part of the cloth. The sampling rubber pad 501 is a rubber elastic structure, and the edge of the bottom can be attached to the surface of the cloth to assist in isolation. When the cloth near the inner circle of the lower pressing ring frame 303 leaks, it can be absorbed by the outer circle water absorption sponge 502, and drained through the drain pipe 3031. After the subsequent cloth test is completed, the control valve 402 is opened to control the suction ring 403 to suck, and the suction pipe 503 will also suck back. At this time, the water absorption paper 504 is not easy to drip when it has more water attached to it. The water absorption paper 504 can be removed from the sampling rubber pad 501 to measure the weight. Conversely, if the cloth is not clamped by the clamping spring piece 602, the clamping spring piece 602 can be elastically attached to the power strip 6011. At this time, the positioning electromagnet 103 can magnetically attract the lower pressing screw 301. When the lower pressing screw 301 presses the clamped cloth, the protruding strip on the positioning electromagnet 103 will be inserted into the groove on the lower pressing screw 301 to limit the rotation of the lower pressing screw 301. The staff needs to adjust in time. After the subsequent cloth test is completed, the other side of the cloth needs to be tested, and the cloth can be directly turned over by removing it from the flat marking piece 6.
