A gear 33 is fixedly connected to the output shaft of the drive motor 32 by means of key connection. The gear 33 meshes with the rack 30.

[0028] Refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the ignition assembly includes a mounting base 7 installed in the placement box 5 by means of bolt connection. Two bottom blocks 8 are installed on the mounting base 7 by means of welding. Two first elastic members 9 are fixedly connected to the two bottom blocks 8 by means of welding. Two first support blocks 10 are fixedly connected to the two first elastic members 9 by means of welding. A fuel bottle 11 is placed on the two first support blocks 10. One side of the tester body 1 close to the placement box 5 is installed with a support bottom plate 18 by means of bolt connection. Two first sliding rails 19 are installed on the support bottom plate 18 by means of bolt connection. A sliding plate 20 is horizontally slidably arranged on the two first sliding rails 19. A burner 21 is installed on the sliding plate 20 by means of bolt connection. A telescopic tube 22 is slidably arranged in the burner 21. A gas pipe 12 is connected and communicated between the telescopic tube 22 and the fuel bottle 11. One side of the tester body 1 where the support bottom plate 18 is installed is installed with an igniter 26 by means of bolt connection. The igniter 26 is located above the burner 21. A servo motor 24 and a fixed seat 25 are respectively installed on both sides of the upper part of the support bottom plate 18 by means of bolt connection. A threaded rod 23 is rotatably arranged on the fixed seat 25. The output shaft of the servo motor 24 is fixedly connected to the threaded rod 23 through a coupling. The threaded rod 23 is in threaded connection with the sliding plate 20.

[0029] Refer to Figure 4 As shown, the clamping assembly includes a lower clamping plate 13 slidably arranged on one side of the tester body 1. Two support columns 14 are fixedly connected to the lower clamping plate 13 by means of welding. An upper clamping plate 15 is slidably arranged on the two support columns 14. Two positioning columns 16 are fixedly connected to the lower clamping plate 13 by means of welding. The upper clamping plate 15 is slidably connected to the positioning columns 16. A second elastic member 17 for pushing the upper clamping plate 15 close to the lower clamping plate 13 is wound around the support columns 14.

[0030] When it is necessary to detect the flame retardancy of a fabric, the fabric is cut into a specified size. Then, the lower clamping plate 13 is slid out from the tester body 1, and the upper clamping plate 15 is slid upward along the support column 14. At this time, the second elastic member 17 is compressed and deformed. Subsequently, the fabric sample is placed between the lower clamping plate 13 and the upper clamping plate 15. After releasing the upper clamping plate 15, the second elastic member 17 pushes the upper clamping plate 15 to reset, and the fabric sample is clamped and fixed by the lower clamping plate 13 and the upper clamping plate 15 together. Then, the lower clamping plate 13 is slid into the tester body 1. Subsequently, the fuel bottle 11 is opened, and the fuel is input into the flame igniter 21 through the fuel pipe 12 and the telescopic pipe 22. By pressing the button 3, the igniter 26 ignites the fuel in the flame igniter 21. Then, the servo motor 24 is controlled to drive the threaded rod 23 to rotate on the fixed seat 25, so that the threaded rod 23 drives the sliding plate 20 to slide downward along the first slide rail 19 toward the lower clamping plate 13. At this time, the sliding plate 20 drives the flame igniter 21 to move, and at the same time, the telescopic pipe 22 extends. The fabric sample is ignited by the ignited flame on the flame igniter 21. After the flame of the flame igniter 21 burns the fabric sample for 10 seconds, the servo motor 24 is controlled to drive the threaded rod 23 to rotate in the reverse direction, so that the flame igniter 21 moves away from the fabric sample. At this time, the flame retardancy of the fabric sample is measured according to the combustion situation of the fabric sample; when waste is generated after the fabric sample burns, the waste falls into the loading frame 27. When cleaning is required, the glass door 4 is rotated and opened, and then the driving motor 32 is started to drive the gear 33 to rotate and engage with the rack 30, so that the rack 30 drives the scraper 29 to slide outward along the second slide rail 28 from the tester body 1, and the scraper 29 scrapes off the waste on the loading frame 27 and clears it out.

[0031] Embodiment 2: On the basis of Embodiment 1, refer to Figure 7 As shown, it further includes four second support blocks 34 installed on the installation base 7 by welding. The second support blocks 34 are provided on both sides of the two bottom blocks 8. A rotating shaft 35 is fixedly connected to the second support blocks 34 by welding. A clamping block 36 for clamping the fuel bottle 11 is rotatably arranged on the rotating shaft 35. The first support block 10 is in contact and cooperation with the clamping block 36.

[0032] When the fuel in the fuel bottle 11 is insufficient, the lid 6 is rotated and opened, and the fuel bottle 11 is lifted upward. At this time, the first elastic member 9 pushes the first support block 10 to reset upward, so that the first support block 10 disengages from the clamping block 36. At the same time, under the influence of the center of gravity, the clamping blocks 36 on both sides flip to both sides along the rotating shaft 35, so that the clamping block 36 releases the fuel bottle 11. After placing the fuel bottle 11 filled with fuel on the first support block 10, the first support block 10 compresses the first elastic member 9, and at the same time, the first support block 10 presses down the clamping blocks 36 on both sides, so that the clamping blocks 36 on both sides rotate toward the middle along the rotating shaft 35 to jointly clamp and fix the fuel bottle 11, which is more convenient when replacing and fixing the fuel bottle 11.

[0033] Refer toFigure 8 As shown, it also includes two fixing rings 37 fixedly connected inside the tester body 1 near one side of the lower clamping plate 13 by welding. Two guiding rings 38 are fixedly connected to the upper clamping plate 15 by welding. A connecting rope 39 is fixedly connected to one fixing ring 37 by tying a knot. One side of the connecting rope 39 passes through the two guiding rings 38 and the other fixing ring 37. One end of the connecting rope 39 is fixedly connected to a weight 40 by tying a knot. A first support frame 41 is installed on the support bottom plate 18 by bolt connection. A first proximity switch 42 for detecting the flame igniter 21 is installed on the first support frame 41 by bolt connection. On one side of the tester body 1 far from the support bottom plate 18, a second support frame 43 is installed by bolt connection. A second proximity switch 44 for detecting the weight 40 is installed on the second support frame 43 by bolt connection. The second support frame 43 is located directly below the weight 40.

[0034] When conducting the flame retardancy test on the fabric sample, when the flame igniter 21 approaches the lower clamping plate 13, the first proximity switch 42 controls the start of timing after detecting the passing of the flame igniter 21. When the fabric sample burns, the connecting rope 39 is burned off. At this time, the weight 40 drops and lands on the second support frame 43. At this time, the second proximity switch 44 controls the stop of timing when detecting the weight 40. The timing is displayed through the display screen 2, so as to know the flame retardant performance of the fabric.

[0035] Refer to Figure 2 and Figure 4 As shown, a telescopic sleeve 45 is sleeved on the support column 14, and the second elastic member 17 is located inside the telescopic sleeve 45; a scale mark 46 is provided on the upper clamping plate 15; a filter net 47 is embedded in the exhaust pipe 101.
