[0030] Embodiment 1

[0031] Please refer to Figure 1 、 Figure 4 and Figure 5 A flame retardancy test device for down fabrics with multiple synchronous detections, comprising: a working box 1 and a placement platform 3; a clamping component 8 and a bracket 9 are provided in the inner cavity of the working box 1, the bracket 9 is located below the clamping component 8, and a combustion device 10 (including a combustion nozzle and an intake pipe communicated with the combustion nozzle) is provided on the bracket 9; a camera 11 is provided at the top of the inner cavity of the working box 1, and a display device 2 (a display) is provided on the outer side wall of the working box 1, and the display device 2 is connected to the camera 11 for receiving the images captured by the camera 11.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 One side of the working box 1 is open, and the open area faces the placement platform 3. A plurality of placement grooves 4 are formed on the top wall of the placement platform 3, and a fixing component 5 is provided on the top wall of the placement platform 3. The plurality of placement grooves 4 are arranged in sequence and spaced apart along the horizontal direction of the open mouth of the working box 1, and a limiting component is provided in the placement groove 4;

[0033] Among them, please refer to Figure 2 、 Figure 3 and Figure 6 The fixing component 5 includes a mounting frame 51, a moving member 52 (the moving member 52 is a plate-shaped member), a first driving member 53 (such as an electric telescopic rod), a pressing plate 54 and an elastic member 55 (a spring). The mounting frame 51 is mounted on the top wall of the placement platform 3, the moving member 52 is slidably arranged on the mounting frame 51, the first driving member 53 is mounted on the mounting frame 51, and the moving end of the first driving member 53 is connected to the moving member 52 for driving the moving member 52 to move up and down; a mounting hole 57 is formed through the side wall of the moving member 52 away from the working box 1, the pressing plate 54 is slidably inserted into the mounting hole 57, and an elastic member 55 is provided between the moving member 52 and the pressing plate 54, and the pressing plate 54 is L-shaped;

[0034] It should be noted that there are a plurality of pressing plates 54 and mounting holes 57, and the plurality of pressing plates 54 correspond to the plurality of placement grooves 4 one by one;

[0035] Please refer to Figure 6 、 Figure 7 and​​​​Figure 8 , the limiting component includes a slot 59 provided at the bottom of the inner cavity of the placement groove 4, a pointed block 510 provided in the slot 59, and a first electromagnet 513 provided in the inner cavity of the slot 59. The first electromagnet 513 is located below the pointed block 510. The top end of the pointed block 510 is conical. A pressing member 58 is provided on a pressing plate 54, and a travel switch 56 is provided on the moving member 52. The travel switch 56 is located on the moving path of the pressing member 58, and the travel switch 56 is used to control the energization of the first electromagnet 513.

[0036] Please refer to Figure 4 and Figure 5 , the clamping component 8 includes a mounting plate 81, two clamping plates 83, a second driving member 82 (such as an electric telescopic rod), and a third driving member 84 (such as an electric telescopic rod); the two clamping plates 83 are slidably provided on a side wall of the mounting plate 81 facing the placement platform 3. The second driving member 82 is provided on the mounting plate 81, and the moving end of the second driving member 82 is connected to the clamping plate 83 for driving the two clamping plates 83 to approach or move away from each other; the third driving member 84 is provided on the side wall of the working box 1, and the moving end of the third driving member 84 is connected to the mounting plate 81 for driving the mounting plate 81 to move, so that the mounting plate 81 moves closer to the placement platform 3, enabling the clamping plates 83 to clamp the fabric.

[0037] Working principle: Place the fabric to be tested in the placement groove 4, and expose the end of the fabric facing the working box 1 outside the placement platform 3 (ensuring that the clamping component 8 can clamp the end of the fabric). The first driving member 53 drives the moving member 52 and the pressing plate 54 to move downward, so that the pressing plate 54 contacts the fabric and presses the fabric (the area where the pressing plate 54 contacts the fabric is relatively rough to increase the frictional force between it and the fabric, and the inner wall of the placement groove 4 is smooth to reduce the frictional force between the fabric and the placement groove 4); the clamping component 8 works, and the third driving member 84 drives the mounting plate 81 to move closer to the placement platform 3. When the end of the fabric is between the two clamping plates 83, the second driving member 82 works to make the two clamping plates 83 move closer to each other and clamp the end of the fabric; then the third driving member 84 drives the mounting plate 81 to move in the reverse direction, pulling the fabric into the working box 1. During this process, the pressing plate 54 moves with the fabric (the pressing plate 54 slides inside the mounting hole 57 and moves closer to the working box 1) until the pressing member 58 contacts the travel switch 56, causing the first electromagnet 513 to energize and generate a magnetic force to repel the pointed block 510, making it move upward and contact the fabric to fix the fabric. At this time, the third driving member 84 also stops working; then the combustion device 10 works, and the sprayed flame contacts the fabric (during the combustion process, the combustion area can be adjusted, and a single fabric can also be subjected to multi-point combustion testing) to conduct the fabric flame retardancy test. During the test, the camera 11 takes pictures of the state of the fabric (this technology is an existing technology and will not be described in detail here) and transmits it to the display device 2 for the staff to analyze to judge the flame retardancy of the fabric.

[0038] It should be noted that the number of brackets 9 corresponds one-to-one with the number of placement grooves 4, and each bracket 9 is equipped with a combustion device 10 (each bracket 9 can have multiple combustion devices 10 for multi-point combustion testing of the fabric), so that each fabric in each placement groove 4 has a corresponding combustion device 10. And a hydraulic telescopic device is installed inside the working box 1, and the number of hydraulic telescopic devices is the same as and corresponds one-to-one with the number of brackets 9, which is used to push the bracket 9 to move inside the working box 1 to adjust the position of the combustion device 10; and the fabric to be tested is a strip-shaped fabric.

[0039] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 6A collecting box 6 is provided at the bottom of the inner cavity of the working box 1, and an extrusion plate 7 is provided in the collecting box 6. A driving device (such as an electric cylinder) is installed on the collecting box 6, and the moving end of the driving device is connected to the extrusion plate 7; the top of the collecting box 6 is open, which is used to collect substances produced by combustion, and after the test is completed, the clamping component 8 releases the fabric, and the fixing component 5 is reset at the same time (the moving part 52 and the pressing plate 54 move up, and the pressing plate 54 is reset under the action of the elastic part 55, so that it is not in contact with the travel switch 56, and the power supply of the first electromagnet 513 is disconnected to reset the tip block 510), which will release the tested fabric and make it fall into the interior of the collecting box 6; and the driving device works, so that the extrusion plate 7 squeezes the fabric that falls into the collecting box 6, which can have a fire extinguishing effect.

[0040] In this embodiment, as a further optimized solution, please refer to Figure 8 The pointed block 510 includes a magnetic block 5101 and an insert block 5102. The insert block 5102 is rotatably arranged on the top wall of the magnetic block 5101. The magnetic poles of the magnetic block 5101 and the first electromagnet 513 on the side close to each other are the same (a repulsive force will be generated between the two). The top of the insert block 5102 is conical, and a thread is provided on the outer wall of the insert block 5102, and a thread is provided on the inner wall of the slot 59, and the threads of the two cooperate with each other. When the first electromagnet 513 is energized, the first electromagnet 513 generates a magnetic force to repel the magnetic block 5101, causing it to move upward with the insert block 5102. Due to the mutual cooperation of the threads, the insert block 5102 rotates during the upward movement, which facilitates the insertion of the insert block 5102 into the fabric, thereby ensuring the stability of the insert block 5102 in fixing the fabric.

[0041] In this embodiment, as a further optimized solution, please refer to Figure 7 , Figure 8 and Figure 9 A plurality of mounting grooves 511 are provided on the side of the placement platform 3 facing the working box 1, and the plurality of mounting grooves 511 correspond to the plurality of placement grooves 4 one by one. The mounting grooves 511 are located below the placement grooves 4, and a push block 512 is slidably provided in the inner cavity of the mounting groove 511. A second electromagnet 514 is installed inside the mounting groove 511, and the second electromagnet 514 is located on the inner side of the push block 512. A magnetic block is provided on the side of the push block 512 facing the second electromagnet 514, and the magnetic poles of the magnetic block and the second electromagnet 514 that are close to each other are the same; the second electromagnet 514 is energized to generate a magnetic force, which is used to push the push block 512 to move toward the outside of the mounting groove 511 (the push block 512 moves toward the working box 1), contact the end of the fabric of the placement groove 4, lift the end of the fabric, and ensure that the clamping component 8 can clamp the fabric.

[0042] In this embodiment, as a further optimized solution, please refer to Figure 9 and Figure 10The push block 512 includes a kit 5121, a moving block 5122 slidably inserted in the kit 5121, and an elastic element 5123 (spring) provided between the kit 5121 and the moving block 5122. The magnetic member is provided on a side wall of the kit 5121 facing the second electromagnet 514. The kit 5121 is slidably provided in the inner cavity of the installation groove 511. A receiving groove 5125 is provided on the side wall of the moving block 5122. A limit block 5124 is slidably provided in the inner cavity of the receiving groove 5125. The limit block 5124 is fitted with one end of the kit 5121 facing the moving block 5122 to prevent the moving block 5122 from moving toward the kit 5121 (because the elastic element 5123 is in a stretched state, the moving block 512 2 provides a pulling force to move toward the kit 5121), a spring member is provided between the receiving groove 5125 and the limiting block 5124 (for supporting the limiting block 5124), a pulling block 5127 is slidably provided on the moving block 5122 (that is, a groove is provided on the surface of the moving block 5122, and the pulling block 5127 is slidably inserted into the groove), a flexible connecting member 5126 (such as a rope) is provided between the pulling block 5127 and the limiting block 5124, a push rod 515 is provided in the inner cavity of the installation groove 511, the length of the push rod 515 extends to the same direction as the moving direction of the moving block 5122, and the end of the push rod 515 is in contact with one end of the moving block 5122 facing the second electromagnet 514, so as to resist the moving block 5122.

[0043] It should be noted that when the clamping assembly 8 clamps the end of the fabric, the two clamps 83 move closer to each other, exerting pressure on the pull block 5127, causing it to pull the flexible connector 5126, pulling the limit block 5124 into the inner cavity of the storage groove 5125, and releasing the restriction on the moving block 5122. Under the action of the elastic element 5123, the moving block 5122 moves closer to the inside of the kit 5121, so that the moving block 5122 moves out from between the two clamps 83 when they move closer, preventing the clamps 83 from clamping the push block 512; in order to allow the moving push block 512 to be reset, the push block 5122 is moved back to the inside of the kit 5121. A reset spring is installed between 21 and the installation groove 511, the second electromagnet 514 is powered off, and the repulsive force on the kit 5121 disappears. Under the action of the reset spring, the kit 5121 moves toward the inside of the installation groove 511. During this process, the push rod 515 contacts the moving block 5122 and pushes the moving block 5122 to the outside of the kit 5121, so that the limit block 5124 moves out from the inside of the kit 5121. At this time, the flexible connecting member 5126 is not pulled. Under the action of the spring member, the limit block 5124 moves outward and contacts the end of the kit 5121, limiting the moving block 5122.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
