Description

Technical Field

[0001] This utility model relates to the field of flame retardant fabric testing technology, and in particular to a flame retardant performance testing device for flame retardant reinforced nylon. Background Technology

[0002] Flame-retardant reinforced nylon is an engineering plastic made by compounding and extruding nylon resin with glass fiber and flame retardant through a twin-screw extruder. After the production of flame-retardant reinforced nylon, its flame-retardant performance is tested by a flame-retardant performance testing device.

[0003] A publicly available technical solution, CN211148554U, discloses a flame-retardant performance testing device for flame-retardant reinforced nylon. The device includes a test chamber and a water tank located at the bottom of one side of the test chamber for dust removal. A movable plate is located at the top of the inner cavity of the test chamber, and an adjustment mechanism is installed inside the movable plate to adjust its position and height. Two nylon fabrics of the same size, one before and one after flame-retardant enhancement, are placed in two clamping mechanisms. A PLC controller then controls two igniters to operate simultaneously. A servo motor drives a lead screw to rotate, causing the movable plate to move downwards, which in turn moves the two nylon fabrics downwards. Through a viewing window, the device observes which nylon fabric ignites first as it approaches the igniter, thus providing a relatively simple and intuitive way to determine whether the flame retardancy of the nylon fabric has been enhanced.

[0004] In actual implementation, the above technical solution involves fixing the fixed plate on the clamping mechanism to the bottom of the movable plate, and clamping the nylon fabric with spring clips on the fixed plate. This makes it inconvenient to adjust the position of the clamping components according to the size of the fabric. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4A flame retardant performance testing device for flame-retardant reinforced nylon includes a testing component 1, a lifting component 3 is installed inside the testing component 1, and a material clamping component 5 for clamping the test material is provided at the bottom of the lifting component 3. A clamping adjustment component 4 for adjusting the position of the material clamping component 5 is installed on one side of the material clamping component 5.

[0028] The clamp adjustment assembly 4 includes a clamp mounting plate 401, a material clamping assembly 5 is installed on the side of the clamp mounting plate 401, a guide slider 402 is fixed on the top of the clamp mounting plate 401, and a bidirectional lead screw 403 is connected inside the guide slider 402 through a threaded sleeve.

[0029] The material clamping assembly 5 includes a clamping back plate 501 fixed to the side of the clamping mounting plate 401. The material clamping assembly 5 also includes a fixed chuck 504 fixed to one side of the clamping back plate 501. A lifting chuck 503 is slidably mounted above the fixed chuck 504. The lifting chuck 503 is rotatably connected to a clamping screw 502 through a threaded sleeve. The clamping screw 502 is mounted on the top of the fixed chuck 504 through a bearing.

[0030] The clamp adjustment assembly 4 also includes a transmission bevel gear 408 fixed in the middle of the bidirectional lead screw 403. A connecting bevel gear 407 is meshed on one side of the transmission bevel gear 408, and a transmission shaft 409 is fixed on the inner side of the two sets of connecting bevel gears 407. An output bevel gear 406 is fixed in the middle of the transmission shaft 409, and a driving bevel gear 405 is meshed on one side of the output bevel gear 406. An input shaft 404 is fixed on the top of the driving bevel gear 405.

[0031] By adopting the above technical solution, the position of the material clamping assembly 5 can be adjusted according to the required dimensions of the flame-retardant reinforced nylon. During adjustment, the input shaft 404 can be rotated, which drives the active bevel gear 405 to rotate. Under the action of the teeth, the active bevel gear 405 can drive the output bevel gear 406 to rotate, which in turn drives the transmission shaft 409 to rotate. The connecting bevel gears 407 at both ends of the transmission shaft 409 rotate, and the connecting bevel gears 407 can drive the transmission bevel gear 408 to rotate through their teeth. The transmission bevel gear 408 can then drive the bidirectional lead screw 403 to rotate. Since the threads at the left and right ends of the bidirectional lead screw 403 are opposite, the threaded sleeves on the bidirectional lead screw 403 can drive the two sets of guide sliders 402 to move in opposite directions, thereby driving the clamp through the guide sliders 402. The mounting plate 401 slides, adjusting the distance between the two sets of clamp mounting plates 401, thereby adjusting the distance of the material clamping assembly 5 installed on the clamp mounting plate 401. The flame-retardant reinforced nylon is clamped on the material clamping assembly 5. After rotating the clamping screw 502, the lifting chuck 503 can be moved on the clamp back plate 501. The lifting chuck 503 and the fixed chuck 504 can clamp the flame-retardant reinforced nylon, which is convenient for subsequent flame-retardant testing. Through the clamp adjustment assembly 4, rotating the input shaft 404 can drive the two bidirectional screws 403 to rotate through multiple sets of bevel gears, thereby adjusting the distance between the clamp mounting plates 401, and thus adjusting the distance of the material clamping assembly 5 installed on the clamp mounting plate 401, which is convenient for the material clamping assembly 5 to clamp and fix flame-retardant reinforced nylon of different sizes.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the test assembly 1 includes a test box 101. The front end of the test box 101 is rotatably connected to a door 102 via a hinge, and an observation window 103 is embedded inside the door 102. An igniter 104 is installed inside the test box 101. A water spray assembly 2 is provided inside the test box 101. The water spray assembly 2 includes a water tank 201 fixed above the test box 101. A connecting water pipe 202 is fixedly connected to the bottom of the water tank 201, and a nozzle 203 is fixedly connected to the end of the connecting water pipe 202. A support frame 204 is welded to the side of the clamp mounting plate 401.

[0033] The lifting assembly 3 includes a lead screw motor 302 fixed on the top of the test box 101. The power output end of the lead screw motor 302 is fixed with a lifting lead screw 301, and the outside of the lifting lead screw 301 is connected to a lifting plate 303 through a threaded sleeve. The bottom of the lifting plate 303 is provided with a guide groove 304.

[0034] By adopting the above technical solution, after the flame-retardant reinforced nylon is clamped on the material clamping assembly 5, the igniter 104 is activated and can ignite the flame-retardant reinforced nylon to conduct a flame-retardant test. If the flame-retardant reinforced nylon does not have a good flame-retardant effect and burns, the valve installed on the connecting water pipe 202 can be opened, and the water in the water tank 201 can flow out from the connecting water pipe 202 under the action of gravity and be sprayed downward through the nozzle 203 to extinguish the fire on the burning material. Through the set water spray assembly 2, water can be sprayed downward through the nozzle 203 to extinguish the fire on the burning material, avoiding damage to the test box 101 caused by the burning of the test material.

[0035] Working principle: Rotating the input shaft 404 drives the driving bevel gear 405 to rotate. Under the action of the teeth, the driving bevel gear 405 drives the output bevel gear 406 to rotate. The output bevel gear 406 drives the transmission shaft 409 to rotate. The connecting bevel gears 407 at both ends of the transmission shaft 409 rotate, and the connecting bevel gears 407 drive the transmission bevel gear 408 to rotate through their teeth. The transmission bevel gear 408 drives the double-acting lead screw 403 to rotate. Since the threads at the left and right ends of the double-acting lead screw 403 are opposite, the threaded sleeve on the double-acting lead screw 403 drives the two sets of guide sliders 402 to move in opposite directions. This causes the clamp mounting plate 401 to slide through the guide sliders 402, adjusting the two sets of clamp mounting plates 401. The distance between them is adjusted, thereby adjusting the distance of the material clamping assembly 5 installed on the clamp mounting plate 401. The flame-retardant reinforced nylon is clamped on the material clamping assembly 5. After rotating the clamping screw 502, the lifting chuck 503 can move on the clamp back plate 501. The lifting chuck 503 and the fixed chuck 504 can clamp the flame-retardant reinforced nylon. After the igniter 104 is activated, the igniter 104 can ignite the flame-retardant reinforced nylon and conduct a flame-retardant test on the flame-retardant reinforced nylon. If the flame-retardant reinforced nylon does not have a good flame-retardant effect and combustion occurs, the valve installed on the connecting water pipe 202 can be opened. The water in the water tank 201 can flow out from the connecting water pipe 202 under the action of gravity and be sprayed downward through the nozzle 203 to extinguish the fire on the burning material.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
