Description

Technical Field

[0001] The utility model relates to the technical field of recycled FRP fiber monofilaments, and particularly to a drawing test device for recycled FRP fiber monofilaments with adjustable arbitrary angles. Background Technique

[0002] Recycled FRP (i.e., fiber-reinforced composite material) fiber monofilaments refer to single fibers that are remanufactured by recycling waste FRP materials through certain treatments and processing. These fibers can be used to manufacture new composite materials, thereby achieving the recycling of materials and reducing the environmental impact of waste. The preparation technology of recycled FRP fiber monofilaments is an important part of the circular economy in the textile industry, which helps to improve the efficiency of resource recycling and reduce environmental pollution.

[0003] The drawing test device for recycled FRP fiber monofilaments is a device used to test the interfacial shear performance between fibers and the matrix in composite materials. This device measures the performance parameters of recycled FRP fiber monofilaments by stretching them. These parameters are crucial for understanding and improving the performance of composite materials. Researchers can evaluate the effects of different fiber surface treatments, different matrix materials, or different interfacial treatment methods on the interfacial performance of composite materials.

[0004] Although the existing drawing test devices for recycled FRP fiber monofilaments play an important role in the mechanical property evaluation of composite materials, they have some limitations in design. Once the device is installed and fixed on the test bench, its angle and orientation become relatively fixed, lacking the necessary flexibility, which restricts the adjustment ability of the staff during the test, making it difficult to observe and record the dynamic changes during the test process and to monitor the test parameters in real time. Due to the fixed angle, the staff may need to frequently change their position or perspective to obtain a clear test view, which not only affects the test efficiency but also may miss key test phenomena due to poor perspective. Therefore, a drawing test device for recycled FRP fiber monofilaments with adjustable arbitrary angles is proposed to solve the above problems. Content of the Utility Model

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , a regenerated frp fiber monofilament drawing test device with adjustable arbitrary angle in this embodiment includes a mounting base 1. A adjusting mechanism 2 is arranged on the top of the mounting base 1, and a frp fiber monofilament drawing test mechanism 3 is arranged outside the adjusting mechanism 2;

[0026] The adjusting mechanism 2 includes a rotating shaft 201, a plugging sleeve 202, a plugging rod 203, a limit pin 204, a support rod 205, a connecting bearing 206 and a turning handle 207. The rotating shaft 201 is rotatably connected to the top of the mounting base 1. The plugging sleeve 202 is fixedly installed at the top of the rotating shaft 201. The plugging rod 203 is inserted into the inside of the plugging sleeve 202. The limit pin 204 is inserted into the inside of the plugging sleeve 202. The support rod 205 is fixedly installed at the top of the plugging rod 203. The connecting bearing 206 is fixedly installed on the right side of the support rod 205. The turning handle 207 is rotatably connected to the inside of the support rod 205.

[0027] Furthermore, the FRP fiber monofilament drawing test mechanism 3 includes a connecting plate 301, a bottom plate 302, a fixture plate 303, a clamping block 304, a threaded fixing rod 305, a threaded shaft 306, a high-strength glass protective cover 307, a first magnetic plate 308, a second magnetic plate 309, and a scale 310. A connecting plate 301 is fixedly installed on the right side of the connecting bearing 206. A bottom plate 302 is fixedly installed at the bottom of the connecting plate 301. A fixture plate 303 is arranged on the top of the bottom plate 302. A clamping block 304 is arranged on the front of the fixture plate 303. A threaded fixing rod 305 is threadedly connected inside the clamping block 304. A threaded shaft 306 is rotatably connected inside the bottom plate 302. A high-strength glass protective cover 307 is slidably connected to the top of the bottom plate 302. A first magnetic plate 308 is fixedly installed inside the connecting plate 301. A second magnetic plate 309 is fixedly installed on the left side of the high-strength glass protective cover 307. A scale 310 is fixedly installed on the front of the bottom plate 302.

[0028] Specifically, the horizontal adjustment of the FRP fiber monofilament drawing test mechanism 3 is mainly achieved by relying on the rotating shaft 201. When it is necessary to adjust the horizontal direction of the FRP fiber monofilament drawing test mechanism 3, the operator manually rotates the rotating shaft 201, driving the entire FRP fiber monofilament drawing test mechanism 3 to rotate horizontally around the center line of the rotating shaft 201. When the required angle is reached, the rotation is stopped, thus achieving precise horizontal adjustment.

[0029] Specifically, the vertical adjustment of the FRP fiber monofilament drawing test mechanism 3 involves the connecting bearing 206 and the turning handle 207. By rotating the turning handle 207 on the connecting bearing 206, the operator can make the FRP fiber monofilament drawing test mechanism 3 on the right side of the support rod 205 rotate around itself, thereby achieving smooth vertical adjustment, thus achieving precise vertical adjustment.

[0030] Specifically, the height adjustment of the FRP fiber monofilament drawing test mechanism 3 is completed by the plug-in sleeve 202, the plug-in rod 203, and the limit pin 204. The operator first removes the limit pin 204, which allows the plug-in rod 203 to freely move up and down inside the plug-in sleeve 202. Subsequently, the operator pulls up the support rod 205. When the required height is reached, the operator reinserts the limit pin 204, passing it through the corresponding limit holes on the plug-in sleeve 202 and the plug-in rod 203 for fixation, thus achieving precise height adjustment of the FRP fiber monofilament drawing test mechanism 3.

[0031] Specifically, the regenerated FRP fiber monofilament is clamped and fixed between two fixture plates 303. The clamping block 304 of the fixture plate 303 fixes the regenerated FRP fiber monofilament through a threaded fixing rod 305 to ensure that the fiber monofilament is firmly clamped. By rotating the threaded shaft 306, another fixture plate 303 is gradually moved away from one of the fixture plates 303 to apply pressure to the regenerated FRP fiber monofilament, simulating its stress condition during actual use. The scale 310 is used to measure the displacement of the fiber monofilament during the pulling process. When the regenerated FRP fiber monofilament cracks, the displacement distance of another fixture plate 303 is recorded, so as to calculate key performance parameters such as its tensile strength and elastic modulus. Through this kind of test, researchers can evaluate the mechanical properties of the regenerated FRP fiber monofilament and provide important data support for the design and optimization of composite materials.

[0032] Specifically, the high-strength glass protective cover 307 not only provides a strong protective barrier for the entire pulling test process, but also ensures the stability and safety of the test. This transparent high-strength glass protective cover 307 can resist the flying debris that may be generated during the pulling process, effectively preventing accidental injuries caused by fiber fracture. At the same time, it also allows the operator to clearly observe the test process without contacting the dangerous area, ensuring the accurate recording of the test and the accuracy of data collection.

[0033] In summary, for the pulling test device of the regenerated FRP fiber monofilament with adjustable arbitrary angle, through the provided adjustment mechanism 2, the horizontal direction, vertical direction and height of the pulling test mechanism 3 of the FRP fiber monofilament can be conveniently adjusted. It allows the operator to easily adjust the angle of the pulling test mechanism 3 of the FRP fiber monofilament without moving the test bench, ensuring the best viewing angle to observe the test process, improving the efficiency of the test and the accuracy of data collection. It solves the problem that once the device is installed and fixed on the test bench, its angle and orientation become relatively fixed, lacking the necessary flexibility, restricting the adjustment ability of the staff to the device during the test, making it difficult to observe and record the dynamic changes during the test process and to monitor the test parameters in real time. Due to the fixed angle, the staff may need to frequently change their positions or viewing angles to obtain a clear test view, which not only affects the efficiency of the test, but may also miss key test phenomena due to poor viewing angles.
