Description

Technical Field

[0001] The present invention relates to the technical field of cloth detection, and in particular to a knitted cloth quality detection device. Background Art

[0002] Water penetration tester is a textile testing equipment used to evaluate the waterproof performance or moisture resistance of textiles. This equipment tests fabric samples by simulating rain penetration conditions and water penetration under high pressure to determine its ability to prevent water penetration.

[0003] When using an existing water seepage tester to test fabric for water seepage, the test area is first filled with water, and then the fabric is placed on the test area to eliminate the gas on the bottom of the fabric. However, when the fabric is placed manually, there is a slight tilt of the fabric, causing one side of the fabric to contact the edge of the container first, which destroys the surface tension of the water in the test area, causing the water in the container to overflow along the bottom of the fabric. The water in the test area is reduced, and there is excess gas space, which forms a bubble area after the fabric is placed on the test area. In subsequent inspections, the bubble area will not only affect the judgment of the staff, resulting in erroneous test results, but also change the actual force of water on the fabric, interfere with the normal process of liquid passing through the fabric, and affect the accuracy and repeatability of the test.

[0004] Furthermore, the fixing clamps on the existing water seepage testing machines adopt an upper and lower clamping method to fix the fabric. When the fabric expands upward due to the water pressure, it squeezes the inner edge of the upper clamp, which increases the pressure of the fabric on the fabric by the inner edge of the upper clamp, resulting in indentations at the clamping position of the fabric. When the fabric is subsequently subjected to strength tests such as pulling, the fabric has lower strength at the indented position than other positions of the fabric and is more likely to be pulled and torn, resulting in the detected tensile strength of the fabric being lower than the actual standard strength, affecting the quality judgment of the fabric. Summary of the invention

[0005] In order to overcome the shortcomings of existing water permeability testing machines that cannot remove the gas in the test area, resulting in erroneous test results, and at the same time exerting great pressure on the cloth clamping position, resulting in indentations at the cloth clamping position, affecting subsequent judgment of the cloth quality, the present invention provides a knitted cloth quality detection device.

[0029] It also includes a fixing component, a first driving member 3, a partition 4, a fixing rod 5, a connecting pipe 6, and a detection component; a fixing component is arranged on the detection machine 1; two first driving members 3 which are symmetrical in front and back are arranged on the water injection part 1001, and the first driving member 3 is an electric push rod; a partition 4 is commonly arranged on the telescopic ends of all the first driving members 3; the partition 4 is arranged in a frustum shape with a hollow lower part; a fixing rod 5 is arranged on the water injection part 1001; a connecting pipe 6 is slidably connected to the fixing rod 5; a receiving part 6001 is arranged on the connecting pipe 6; the receiving part 6001 is located on the upper side of the fixing rod 5; a protrusion 6002 is arranged on the connecting pipe 6; and a detection component is arranged on the detection machine 1.

[0031] Furthermore, when the tested fabric is subjected to water pressure, the middle part of the fabric will bulge upward to form an arc. In order to prevent damage to the clamping position of the fabric and to avoid affecting subsequent detection, the upper side surface of the water container 101 is arranged to be inclined with the inner side surface higher than the outer side surface; the lower side surface of the fixing ring 104 is arranged to be inclined to fit with the upper side surface of the water container 101.

[0032] The detection component includes a water injection pipe 201, a drainage pipe 202, a water absorption membrane 203 and a humidity sensor 204; the water injection pipe 201 is fixedly connected to the detection machine 1; the water injection pipe 201 is connected to the water injection part 1001; the drainage pipe 202 is fixedly connected to the detection machine 1; the drainage pipe 202 is connected to the leakage hole 2001; the water absorption membrane 203 is fixedly connected to the upper side of the fixing ring 104; the water absorption membrane 203 adopts intelligent fiber and a flexible material; a plurality of humidity sensors 204 in a ring array are fixedly connected to the connecting plate 103; the humidity sensor 204 is connected to the water absorption membrane 203.

[0033] Furthermore, in order to enhance the drainage effect of the water overflowing into the water tray 2, the upper side of the water tray 2 is arranged to be inclined toward the leakage hole 2001.

[0034] Furthermore, the water outlets of the connecting pipe 6 and the water injection pipe 201 are arranged in a staggered state to prevent the air bubbles contained in the connecting pipe 6 from directly entering the connecting pipe 6 during water injection.

[0035] It also includes a third driving member 301 and a pressing plate 302 ; the third driving member 301 is fixedly connected to the lower side of the connecting plate 103 , and the third driving member 301 is an electric push rod; the pressing plate 302 is fixedly connected to the telescopic end of the third driving member 301 .

[0036] It also includes a guide plate 401 and a baffle 402; a plurality of guide plates 401 in a vertical array are fixedly connected to the connecting pipe 6; each guide plate 401 is funnel-shaped; a plurality of baffles 402 in a vertical array are fixedly connected to the connecting pipe 6; each guide plate 401 is conical; each guide plate 401 is provided with a plurality of through holes 40201 in a circular array; each baffle 402 is located below the corresponding guide plate 401.

[0037] The present invention squeezes the gas under the cloth to the lower side of the partition 4 through the connecting pipe 6 through the partition 4, thereby solving the problem that the residual gas under the cloth when the worker places the cloth leads to the biased test results and the inability to accurately judge the true waterproof performance of the cloth. The specific process is as follows:

[0038] When the fabric is subjected to a hydrostatic pressure test, the external water pump is first controlled to pump water from the water injection pipe 201 to the water injection part 1001, so that the water accumulates in the collecting chamber 10101. When the collecting chamber 10101 is full of water, the water in the collecting chamber 10101 overflows upward into the test chamber 10102 through the connecting pipe 6. When the water in the test chamber 10102 overflows into the water receiving tray 2, the water supply to the water injection pipe 201 is stopped. Then the staff places the fabric on the upper side of the water container 101 so that the fabric contacts the upper side of the connecting pipe 6, and controls the second driving member 102 to drive the connecting plate 103 and the fixing ring 104 to descend, so that the fixing ring 104 drives the water-absorbing membrane 203 to press the cloth onto the water container 101, and then controls the first driving member 3 to drive the partition 4 to fit the inner wall of the collecting chamber 10101 and rise. At this time, the internal volume of the collecting chamber 10101 increases and generates negative pressure, and the internal volume of the test chamber 10102 decreases and generates positive pressure, so that the excess gas in the test chamber 10102 that fits the lower side of the cloth is compressed, and the gas is squeezed into the collecting chamber 10101 through the connecting tube 6, and is intercepted and collected by the partition 4, so as to prevent residual gas on the lower side of the cloth, avoid errors in the results of subsequent tests, and ensure the authenticity of the detected waterproof performance of the cloth.

[0039] It is also considered that when the water permeability of the detected fabric is strong, the compressed gas on the lower side of the fabric carries the water in the water container 101 and precipitates from the upper side of the fabric, so that the water remains on the upper side of the fabric, resulting in errors in the subsequent judgment of the water permeability of the fabric due to the residual water. The specific solution process is as follows:

[0040] When the partition 4 rises to discharge the gas in the test chamber 10102, the third driving member 301 is controlled to drive the pressing plate 302 to descend and fit onto the water-absorbing film 203, and the water-absorbing film 203 is pressed to fit onto the upper side of the fabric, so as to prevent the gas in the test chamber 10102 from driving water to precipitate from the fabric when it is discharged from the upper side of the fabric, thereby avoiding residual water on the upper side of the fabric, and thus avoiding errors in the subsequent judgment of water seepage of the fabric.

[0041] It is also taken into consideration that when the partition 4 moves from the collecting chamber 10101 to the testing chamber 10102, the gas is still in the connecting tube 6 and has not completely entered the collecting chamber 10101. At this time, the bubbles that have not been eliminated and floated up in the connecting tube 6 are blocked and intercepted by the guide plate 401 and the baffle 402, so that the bubbles accumulate between the guide plate 401 and the inner wall of the connecting tube 6 and on the lower side of the baffle 402 during the floating process, preventing the gas that has not been eliminated in the connecting tube 6 from floating up to the lower side of the fabric again, thereby avoiding errors in the results of subsequent tests. When the gas and water in the testing chamber 10102 are transferred to the collecting chamber 10101, the gas and water that enter the connecting tube 6 are normally transferred through the circular hole in the middle of the guide plate 401 and the through hole 40201.

[0042] When the gas on the lower side of the fabric in the test chamber 10102 is exhausted, the partition 4 enters the test chamber 10102, so that the collection chamber 10101 and the test chamber 10102 are completely connected. The partition 4 is set to a hollowed-out truncated cone at the bottom, so that the gas discharged from the connecting tube 6 to the collection chamber 10101 accumulates between the lower side of the partition 4 and the outer wall of the connecting tube 6 to prevent the gas from floating up to the test chamber 10102 again. Then, the third driving member 301 is controlled to drive the pressing plate 302 to rise and separate from the water absorption film 203, and the humidity sensor 204 is turned on to prepare for real-time monitoring of the moisture change on the water absorption film 203. Then, the external water pump is controlled to pump water from the water injection pipe 201 to the water container 101. The water container 101 is pressurized to conduct a hydrostatic pressure resistance test on the fabric. When the fabric is subjected to water pressure, the middle part of the fabric will bulge upward to form an arc. The lower side surface of the fixing ring 104 and the upper side surface of the water container 101 are arranged together in an inclined state that fits each other, so as to prevent the fabric from squeezing the inner edge of the fixing ring 104 when bulging upward due to the water pressure, to prevent the inner edge of the upper clamp from increasing the pressure on the fabric, to prevent the fabric from being damaged at the clamping position, and to avoid affecting subsequent testing. When the fabric is bulged upward due to the water pressure, the moisture that penetrates from the fabric is absorbed by the water absorbing film 203, and the moisture change on the water absorbing film 203 is monitored in real time by the humidity sensor 204, so as to judge the waterproof performance of the fabric.

[0043] When the water seepage test of the fabric is completed, the second driving member 102 is controlled to drive the connecting plate 103 and the fixing ring 104 to rise, thereby releasing the pressing and fixing of the fabric. Subsequently, the water in the water container 101 is pumped out through the water filling pipe 201 through an external pump. At the same time, the water overflowing into the water tray 2 is pumped out through the drain pipe 202 through an external pump, thus completing the drainage work after the test and preparing for the next inspection.

[0044] Example 2

[0045] On the basis of Example 1, Figure 3 and Figure 4As shown, an interception plate 501 is also included; the interception plate 501 is fixedly connected to the upper inner side of the water container 101.

[0046] It also includes a protrusion 502; a plurality of protrusions 502 in a ring array are fixedly connected to the upper side of the connecting pipe 6.

[0047] It is also taken into consideration that when water is injected into the water container 101 and pressurized, water entering the water container 101 from the water injection pipe 201 is mixed with bubbles, and most of the bubbles can be intercepted by the partition 4. However, a small number of bubbles adhere to the inner wall of the water container 101 and float up. The bubbles adhering to the inner wall of the water container 101 and floating up are intercepted by the interception plate 501 to prevent the bubbles from floating to the bottom of the fabric, thereby avoiding errors in the results of subsequent tests.

[0048] When the fabric is subjected to a hydrostatic pressure resistance test, after the fabric inspection in a normal state is completed, the first driving member 3 is controlled to drive the partition 4 to continuously rise, so that the partition 4 rises to the bottom of the protrusion 6002, thereby driving the connecting tube 6 and the protrusion 502 to rise on the fixed rod 5, so that the protrusion 502 squeezes the fabric locally, thereby simulating water seepage in extreme conditions such as local pressure on the fabric, thereby enhancing the reference value of the fabric's waterproof performance. After the fabric inspection is completed, the first driving member 3 is controlled to drive the partition 4 to descend, and the connecting tube 6 descends on the fixed rod 5 after losing the support of the partition 4, so that the receiving portion 6001 is attached to the upper side of the fixed rod 5, preparing for the next simulation test.

[0049] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
