Description

Technical Field

[0001] This utility model relates to the field of fabric flame retardancy testing technology, and in particular to a high-performance fabric flame retardancy testing device. Background Technology

[0002] High-performance fabrics refer to fabrics with special functions or excellent properties, such as breathability, water resistance, and flame retardancy. During the production and processing of some high-performance fabrics, various performance aspects of the fabric are tested to determine the actual performance of the fabric.

[0003] Traditional flame retardancy tests on high-performance fabrics involve directly burning the fabric with an ignition device. The flame retardancy is assessed by observing the burning pattern, changes in the burning location, and the burning time. However, in practice, existing tests can only test one section or one type of fabric, making it difficult to test multiple fabrics simultaneously, hindering comparisons, and making it difficult to ensure the stability of the fabric during testing, thus affecting the test results and reliability. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing tests can only test one section or one type of fabric, making it difficult to test multiple fabrics simultaneously, hindering comparisons, and making it difficult to ensure the stability of the fabric during testing, thus affecting the test results and reliability.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-performance fabric flame retardancy testing device, including a test box, an igniter is provided on the inner wall of the test box, the surface of the igniter is provided with a plurality of ignition heads, and a gas pipe is connected to one side of the igniter. Fixed frames are respectively installed at the four corners of the surface of the test box, and connecting rods are slidably installed on the surface of the fixed frames, and protective covers are fixedly connected to the surface of the connecting rods. A stabilizing device is provided on the surface of the test box, wherein the stabilizing device limits and fixes the fabric strip under test by means of clamps and pressure plates.

[0006] The effect achieved by the above components is as follows: When conducting flame retardancy tests on fabrics, several fabric strips of different materials are first installed and fixed in the test chamber using a stabilizing device. Then, the connecting rods fixed at the four corners of the protective cover are slidably inserted into the fixed frames at the four corners of the test chamber. Finally, the igniter is activated, allowing gas to flow into the gas pipe and into the igniter, causing the ignition head to spray out a burning flame to burn the fabric. At this time, the testers observe and record the different fabric strips.

[0007] Preferably, the stabilizing device includes a fixing plate, which is fixedly connected to the surface of the test box. Two fixing rods are mounted on the surface of the fixing plate, and a clamping plate is slidably inserted into the surface of the two fixing rods. Nuts are threadedly installed on the arc surface of the fixing rods. A stabilizing plate is mounted on the side of the test box away from the fixing plate. Assembly plates are fixedly connected to both sides of the surface of the stabilizing plate, and a sliding rod is slidably installed through the surface of the assembly plate. A pressure plate is mounted on the surface of the two sliding rods. Two rotating shafts are fixedly connected to the surface of the stabilizing plate, and a pressure plate is rotatably connected to the arc surface of the rotating shaft. The pressure plate engages with a groove on the surface of the sliding rod.

[0008] The effects achieved by the above components are as follows: when conducting flame retardancy tests on high-performance fabrics, different fabrics can be tested simultaneously, and the fabrics can be kept taut and straight, making the testing process and results more rigorous and reliable, and also improving the convenience of the testing work and the reliability of the results data.

[0009] Preferably, the stabilizing device further includes a spring sleeved on the arc surface of the slide bar, wherein the two ends of the spring are respectively connected and fixed to the slide bar of the mounting plate.

[0010] The effect achieved by the above components is that, through the setting of the spring, the pressure plate can be moved away from the stabilizing plate under the elastic force of the spring after the test, which facilitates the disassembly of the fabric strip and improves the convenience of the test operation.

[0011] Preferably, the stabilizing device further includes a plurality of reinforcing plates mounted on the surface of the pressure plate, wherein a plurality of protrusions are fixedly connected to the surface of the reinforcing plates.

[0012] The effect achieved by the above components is that, by setting up the reinforcing plate and the protrusion, when the fabric belt is squeezed and limited by the pressure plate, the protrusion can contact and press on the surface of the fabric belt, thereby making the fabric belt better maintain a tight and straight state and improving the limiting effect of the stabilizing device.

[0013] Preferably, the stabilizing device further includes a reinforcing sleeve installed at one end of the card plate, wherein the reinforcing sleeve improves the connection stability between the card plate and the card slot.

[0014] The effect achieved by the above components is that, through the reinforcement sleeve made of rubber, the friction is further increased when the card plate is inserted into the card slot, thereby better ensuring the limiting effect of the pressure plate on the fabric strip.

[0015] Preferably, the stabilizing device further includes an operating plate mounted on the surface of the pressure plate, wherein the operating plate improves the ease of use of the pressure plate.

[0016] The effect achieved by the above components is that, by setting the operating plate, one end of the fabric is located in the groove of the stabilizing plate. By pressing the operating plate on the surface of the pressure plate, the pressure plate can be temporarily stabilized, making it less likely to slip.

[0017] Preferably, the surface of the igniter is provided with a protective component, wherein the protective component ensures stable combustion of the fabric.

[0018] The effect achieved by the above components is that, through the setting of protective components, the fabric is kept stable during combustion and is not easily affected by the surrounding test fabrics.

[0019] Preferably, the protective component includes several arc-shaped plates, which are arranged in pairs and together cover both sides of the ignition head. The arc-shaped plates are also equipped with two combined rods, and positioning frames are inserted into both ends of the combined rods. The positioning frames are fixedly connected to the surface of the igniter.

[0020] The effect achieved by the above components is as follows: When the effect of using the test box is further improved, the two combination rods are inserted into the inner wall of the positioning frame fixedly connected to the surface of the igniter. At this time, the arc plates on the two combination rods are respectively shielded on both sides of the same ignition head. When the ignition head sprays flames to burn the fabric, it is not easy for the flame and the burning fabric to affect the flame retardant test of the surrounding fabric, thus further improving the reliability of the test results.

[0021] The beneficial effects of this utility model are:

[0022] When conducting flame retardancy tests on high-performance fabrics, this invention can ensure that different fabrics are tested simultaneously and that the fabrics are kept taut and straight, making the testing process and results more rigorous and reliable, and also improving the convenience of the testing work and the reliability of the results data.

[0031] Figure 1 and Figure 2 The high-performance fabric flame retardancy testing device shown includes a test chamber 1. An igniter 5 is installed on the inner wall of the test chamber 1. The surface of the igniter 5 is provided with several ignition heads 6, and a gas pipe 7 is connected to one side of the igniter 5. Fixing frames 3 are installed at the four corners of the surface of the test chamber 1. Connecting rods 4 are slidably installed on the surface of the fixing frames 3, and protective covers 2 are fixedly connected to the surface of the connecting rods 4. A stabilizing device 8 is provided on the surface of the test chamber 1. The stabilizing device 8 limits and fixes the fabric strip under test by means of clamping plates 83 and pressure plates 88. A protective component 9 is provided on the surface of the igniter 5.

[0032] Figure 1 , Figure 2 and Figure 3The stabilizing device 8 shown includes a fixed plate 81, which is fixedly connected to the surface of the test chamber 1. Two fixed rods 82 are mounted on the surface of the fixed plate 81, and a clamping plate 83 is slidably inserted into the surface of the two fixed rods 82. Nuts 84 are threadedly installed on the arc surface of the fixed rods 82. A stabilizing plate 85 is mounted on the side of the test chamber 1 away from the fixed plate 81. Assembly plates 86 are fixedly connected to both sides of the surface of the stabilizing plate 85, and sliding rods 87 are slidably installed through the surface of the assembly plates 86. A pressure plate 88 is mounted on the surface of the two sliding rods 87. Two rotating shafts 89 are fixedly connected to the surface of the stabilizing plate 85, and the pressure plate 88 is rotatably connected to the arc surface of the rotating shafts 89. The pressure plate 88 engages with the slots 811 on the surface of the sliding rods 87. When conducting a flame retardancy test on the fabric, several fabric strips of different materials are first placed at both ends in several grooves of the fixed plate 81 and the assembly plate 86, and then the nuts 84 on the fixed rods 82 are rotated until the nuts 84 contact and press against the clamping plate 83. This causes the clamping plate 83 to press and fix one end of the fabric strip, then pull the other end of the fabric strip to straighten it, and then press down the pressure plate 88, causing the slide rod 87, which is fixedly connected to both ends of the pressure plate 88, to slide in the inner wall of the mounting plate 86 on the surface of the stabilizing plate 85 until the pressure plate 88 contacts and presses the fabric strip. Finally, rotate the clamping plate 810 on the rotating shaft 89 so that the clamping plate 810 is engaged in the groove 811 on the surface of the slide rod 87, thus fixing the position of the sub-version and the fabric strip. Then, slide the connecting rod 4, which is fixedly installed at the four corners of the protective cover 2, into the fixing frame 3 at the four corners of the test box 1. Finally, start the igniter 5 so that the gas pipe 7 passes gas into the igniter 5, causing the ignition head 6 to spray out a burning flame to burn the fabric. At this time, the tester observes and records the different fabric strips. At this time, when conducting flame retardant tests on high-performance fabrics, it can be ensured that different fabrics are tested simultaneously and that the fabric is kept taut and straight, making the test process and results more rigorous and reliable, and also improving the convenience of the test work and the reliability of the result data.

[0033] Figure 1 , Figure 2 and Figure 3 The stabilizing device 8 shown also includes a spring 815 sleeved on the arc surface of the slide bar 87. The two ends of the spring 815 are respectively connected and fixed to the slide bar 87 of the mounting plate 86. By setting the spring 815, after the test is completed, the pressure plate 88 can move away from the stabilizing plate 85 under the elastic force of the spring 815, which facilitates the disassembly of the fabric strip and improves the convenience of the test operation.

[0034] Figure 1 , Figure 2 and Figure 3The stabilizing device 8 shown also includes several reinforcing plates 812 mounted on the surface of the pressure plate 88. Several protrusions 813 are fixedly connected to the surface of the reinforcing plates 812. By setting the reinforcing plates 812 and protrusions 813, when the fabric belt is squeezed and limited by the pressure plate 88, the protrusions 813 can contact and press against the surface of the fabric belt, thereby keeping the fabric belt in a tight and straight state and improving the limiting effect of the stabilizing device 8.

[0035] Figure 1 , Figure 2 and Figure 3 The stabilizing device 8 shown also includes a reinforcing sleeve 814 installed at one end of the clamping plate 810. The reinforcing sleeve 814 improves the connection stability between the clamping plate 810 and the clamping groove 811. The rubber reinforcing sleeve 814 further increases the friction when the clamping plate 810 is inserted into the clamping groove 811, thereby better ensuring the limiting effect of the pressure plate 88 on the fabric strip. The stabilizing device 8 also includes an operating plate 816 installed on the surface of the pressure plate 88. The operating plate 816 improves the ease of use of the pressure plate 88. With the operating plate 816, after one end of the fabric is located in the groove of the stabilizing plate 85, the pressure plate 88 can be temporarily stabilized by pressing the operating plate 816 on the surface of the pressure plate 88, making it less likely to slip.

[0036] Figure 1 and Figure 4 The protective assembly 9 shown includes several arc-shaped plates 91, which are arranged in pairs. The arc-shaped plates 91 in the same group cover both sides of the ignition head 6. The arc-shaped plates 91 are also equipped with two combination rods 92. The two ends of the combination rods 92 are respectively inserted into positioning frames 93. The positioning frames 93 are fixedly connected to the surface of the igniter 5. When the effect of the test box 1 is further improved, the two combination rods 92 are respectively inserted into the inner wall of the positioning frames 93 fixedly connected to the surface of the igniter 5. At this time, the arc-shaped plates 91 arranged in pairs on the two combination rods 92 respectively cover both sides of the same ignition head 6. When the ignition head 6 sprays flames to burn the fabric, it is less likely that the flames and the burning fabric will affect the flame retardant test of the surrounding fabric, thus further improving the reliability of the test results.

[0037] Working principle: When conducting a flame retardancy test on the fabric, firstly, several fabric strips of different materials are placed at both ends in several grooves on the fixing plate 81 and the assembly plate 86, respectively. Then, the nut 84 on the fixing rod 82 is rotated until the nut 84 contacts and presses against the clamping plate 83, thereby pressing and fixing one end of the fabric strip. Then, the other end of the fabric strip is pulled to taut it. Next, the pressure plate 88 is pressed down, causing the sliding rod 87, which is fixedly connected to both ends of the pressure plate 88, to slide in the inner wall of the assembly plate 86 on the surface of the stabilizing plate 85, until the pressure plate 88 contacts and presses against the fabric strip. Finally, the clamping plate 810 on the rotating shaft 89 is rotated, causing the clamping plate 810 to engage with the sliding rod 87. When the card slot 811 is in place, the position of the sub-version and the fabric strip is fixed. Then, the connecting rods 4, which are fixedly installed at the four corners of the protective cover 2, are slid into the fixed frames 3 at the four corners of the test box 1. Finally, the igniter 5 is activated, so that the gas pipe 7 is connected to the gas and enters the igniter 5, causing the ignition head 6 to spray out a burning flame to burn the fabric. At this time, the tester observes and records the different fabric strips. When conducting flame retardant tests on high-performance fabrics, it is possible to ensure that different fabrics are tested simultaneously and that the fabrics are kept taut and straight, making the test process and results more rigorous and reliable, and improving the convenience of the test work and the reliability of the results data.

[0038] To further improve the performance of the test box 1, two combination rods 92 are inserted into the inner wall of the positioning frame 93 fixedly connected to the surface of the igniter 5. At this time, the arc plates 91 on the two combination rods 92 are respectively shielded on both sides of the same ignition head 6. When the ignition head 6 sprays flames to burn the fabric, it is less likely that the flames and the burning fabric will affect the flame retardant test of the surrounding fabric, thus further improving the reliability of the test results.
