Description

Technical Field

[0001] The utility model relates to the technical field of testing of phosphorus-containing flame retardant fibers, and specifically relates to a testing device for phosphorus-containing flame retardant fibers. Background Technique

[0002] Functional fibers refer to fibers that, in addition to the existing properties of the fibers, also have some special functions, such as conductive fibers, optical fibers, ion exchange fibers, ceramic particle fibers, temperature-regulating and heat-insulating fibers, bioactive fibers, biodegradable fibers, elastic fibers, high-emissivity far-infrared fibers, fibers that can generate negative ions, antibacterial and deodorant fibers, flame-retardant fibers, fragrance fibers, color-changing fibers, radiation-proof fibers. After the production of phosphorus-containing flame retardant fibers, functional tensile testing of the phosphorus-containing flame retardant fibers is required.

[0003] In the application document of the glass fiber yarn tension testing device proposed in the application number 202320806639.3, when in use, the electric push rod drives the upward movement of the movable seat, thereby performing tension testing on the detected item. When the appearance of the item is deformed or broken, the movable seat will stop moving, and the sensor will immediately sense the vibration transmitted on the movable seat, and then record it. At the same time, a scale is provided on one side of the side plate. Wherever the movable seat stops, that is the tension data of the detected item. At the same time, the control device will also receive and record the data after the movable seat stops.

[0004] Although the above application meets the user's usage requirements to a certain extent, there are still certain defects in the usage process. When fixing multiple phosphorus-containing flame retardant fibers, it is necessary to fix multiple phosphorus-containing flame retardant fibers multiple times, resulting in low efficiency of fixing phosphorus-containing flame retardant fibers, and further causing low testing efficiency of phosphorus-containing flame retardant fibers. Moreover, during the stretching process of the phosphorus-containing flame retardant fibers, the ends of the phosphorus-containing flame retardant fibers are only fixed once, resulting in the easy detachment of the phosphorus-containing flame retardant fibers during stretching. Based on this, the utility model designs a testing device for phosphorus-containing flame retardant fibers to solve the above problems. Content of the Utility Model

[0030] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a phosphorus-containing flame retardant fiber testing device, including a base 1, on the top surface of the base 1, a mounting frame 2 is fixedly installed, at both ends of the top of the mounting frame 2, electric telescopic rods 3 are fixedly installed, inside the mounting frame 2, a fixing component 5 is provided, and the fixing component 5 includes a mounting rod 501, a threaded cylinder 502, a threaded rod 503, a moving plate 504, a connecting column 505, a pressing plate 506, a placement hole 507, a spring telescopic rod 508, a rubber plate 509, an adjusting rod 510 and a pressing rod 511;

[0031] Mounting rods 501 are fixedly connected between the bottoms of the two electric telescopic rods 3 and inside the mounting frame 2. On the top surface of the base 1 and between the two electric telescopic rods 3, threaded cylinders 502 are movably installed. Inside the threaded cylinder 502, a threaded rod 503 is connected by threads. One end of the threaded rod 503 is fixedly connected to a moving plate 504. On the end face of the moving plate 504, connecting columns 505 are evenly fixedly installed. One end of the connecting column 505 is adhered with a pressing plate 506. On the end face of the mounting rod 501, placement holes 507 are evenly opened. Inside one end of the mounting rod 501, spring telescopic rods 508 are evenly fixedly installed. One end of the spring telescopic rod 508 is adhered with a rubber plate 509. One end of the rubber plate 509 is adhered with an adjusting rod 510. One end of the moving plate 504 is installed with a pressing rod 511 by screws. The pressing rod 511 corresponds to one end of the adjusting rod 510. At one end of the top of the pressing rod 511, an inclined plate is welded to facilitate the movement of the adjusting rod 510. An arc angle is opened at one end of the rubber plate 509. The longitudinal section of the pressing plate 506 is arc-shaped to facilitate the fixation of the phosphorus-containing flame retardant fiber. The pressing plate 506 is located inside the placement hole 507. On the top of one threaded cylinder 502, a connecting rod is movably installed. Both ends of the connecting rod are connected to the moving ends of the two electric telescopic rods 3. The connecting column 505 is slidably connected inside the mounting rod 501

[0032] At both ends of the mounting frame 2, protection components 4 are fixedly installed. The protection components 4 include a fixing plate 401, a winding spring 402, a winding roller 403, a protection cloth 404, a magnetic strip 405 and a connecting frame 406;

[0033] Fixing plates 401 are welded to both ends on both sides of the mounting bracket 2. One end of each of the two fixing plates 401 is welded with a winding spring 402. One end of the winding spring 402 is welded with a winding roller 403. A protective cloth 404 is wound around the outer side of the winding roller 403. Magnetic strips 405 are installed at the bottom of the protective cloth 404 and inside the base 1 by screws. The two winding rollers 403 are movably connected to the other two fixing plates 401. The magnetic strips 405 at the bottom of the protective cloth 404 are adsorbed to the magnetic strips 405 inside the base 1. One ends of the two magnetic strips 405 at the bottom of the protective cloth 404 are connected by a connecting frame 406.

[0034] The personnel place the phosphorus-containing flame retardant fiber inside the placement hole 507, and then move in from the end of the rubber plate 509 and the adjusting rod 510, so that the phosphorus-containing flame retardant fiber is located between the rubber plate 509 and the mounting rod 501. At this time, the spring telescopic rod 508 is compressed to initially fix the phosphorus-containing flame retardant fiber. After initially fixing multiple phosphorus-containing flame retardant fibers, the personnel rotate the threaded cylinder 502. Since the threaded cylinder 502 is threadedly connected to the threaded rod 503, the threaded rod 503 is driven to move. The movement of the threaded rod 503 drives the moving plate 504 to move, thereby driving the connecting column 505 and the pressing plate 506 to move. The phosphorus-containing flame retardant fiber is fixed by pressing with the pressing plate 506. At the same time, when the moving plate 504 moves, it contacts and drives the adjusting rod 510, causing the rubber plate 509 to be compressed, and the phosphorus-containing flame retardant fiber is fixed again. It is convenient to fix multiple phosphorus-containing flame retardant fibers synchronously, improve the fixing efficiency of the phosphorus-containing flame retardant fiber, and can double-fix the phosphorus-containing flame retardant fiber to ensure the stability of the phosphorus-containing flame retardant fiber after fixing, and avoid the problem that the two ends of the phosphorus-containing flame retardant fiber break away during the stretching process;

[0035] After fixing the phosphorus-containing flame retardant fiber, then the personnel move the connecting frame 406, drive the magnetic strip 405 to move, and then drive the protective cloth 404 to move, causing the winding roller 403 to rotate and the winding spring 402 to be compressed. Then, the magnetic strip 405 at the bottom of the protective cloth 404 is adsorbed to the magnetic strip 405 inside the base 1 to fix the protective cloth 404. Further, the front and back sides of the mounting bracket 2 can be protected, avoiding the problem that the phosphorus-containing flame retardant fiber breaks and causes danger to the personnel, and ensuring the safety during the test of the phosphorus-containing flame retardant fiber. After the test is completed, the magnetic strip 405 is disengaged, and the winding spring 402 is reset to realize the winding of the winding roller 403, without manual winding by the personnel, reducing the labor intensity of the personnel;

[0036] Then the personnel turn on the electric telescopic rod 3, drive one mounting rod 501 to move, and then drive the phosphorus-containing flame retardant fiber to stretch, realizing the stretching test of the phosphorus-containing flame retardant fiber.
