Description

Technical Field

[0001] This utility model relates to the field of fiber tensile strength testing technology, specifically a PPS fiber tensile strength testing device. Background Technology

[0002] PPS fiber (polyphenylene sulfide fiber) is a new type of special plastic fiber. It is made from polyphenylene sulfide resin (PPS) through melt spinning. PPS fiber has the characteristics of high temperature resistance, high strength and good chemical stability, so it is widely used in many fields.

[0003] The existing method for testing the strength of PPS fibers usually involves fixing both ends of the PPS fiber, pulling both ends of the PPS fiber, and then observing the changes on the surface of the PPS fiber to test the strength of the PPS fiber.

[0004] Existing methods for testing the strength of PPS fibers have some shortcomings. When the two ends of a PPS fiber are pulled to test its tensile strength, the degree of surface change after the PPS fiber is subjected to force cannot be detected, thus affecting the test results. Therefore, we propose a PPS fiber tensile strength testing device. Utility Model Content

[0005] The purpose of this invention is to provide a PPS fiber tensile strength testing device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PPS fiber tensile strength testing device, comprising a rectangular frame and a tensile strength testing component disposed above the rectangular frame. The tensile strength testing component includes a first drive motor fixedly connected to the left outer wall of the rectangular frame. A bidirectional threaded rod is fixedly connected to the output end of the first drive motor. The bidirectional threaded rod movably passes through the outer wall of the rectangular frame and extends into the interior of the rectangular frame. The other end of the bidirectional threaded rod is rotatably connected to the inner wall of the rectangular frame. A first socket block is threadedly connected to the left outer wall of the bidirectional threaded rod, and a second socket block is threadedly connected to the right outer wall of the bidirectional threaded rod. The bottom outer walls of both the first and second socket blocks are slidably connected to the inner wall of the rectangular frame. Rectangular blocks are fixedly connected to the top of the first and second socket blocks respectively. A PPS fiber body is slidably connected to the bottom of the inner wall of the rectangular blocks. By setting the tensile strength testing component, the PPS fiber body can be pulled by the relative distance between the first and second socket blocks, thereby realizing the tensile strength testing of the PPS fiber body.

[0007] Preferably, a screw is threadedly connected to the inner top wall of the rectangular block, an adjusting block is fixedly connected to the outer top wall of the screw, and a clamping block is rotatably connected to the bottom of the screw. The outer wall of the clamping block is slidably connected to the inner wall of the rectangular block, and the bottom of the clamping block is slidably connected to the top of the PPS fiber body. When both ends of the PPS fiber body enter the interior of the rectangular block, the operator rotates the adjusting block to cause the screw to rotate. After the screw rotates, it will cause the clamping block to move downward, so that the clamping block squeezes the surface of the PPS fiber body, thereby clamping and fixing both ends of the PPS fiber body.

[0008] Preferably, a compressive strength testing component is further provided above the rectangular frame. The compressive strength testing component includes a U-shaped connecting plate fixedly connected to the outer wall of the rectangular frame. A horizontal fixing frame is fixedly connected to the other end of the U-shaped connecting plate. The horizontal fixing frame is located above the rectangular frame. A rectangular groove is formed at the top of the horizontal fixing frame. A support frame is fixedly connected to the outer wall of the horizontal fixing frame. A second drive motor is fixedly connected to the top inner wall of the support frame. An output shaft is fixedly connected to the output end of the second drive motor. A gear is fixedly connected to the outer wall of the other end of the output shaft. A rack meshes with the bottom of the gear. The bottom outer wall of the rack is slidably connected to the inner wall of the rectangular groove. The bottom of the rack is fixedly connected to… The device includes a slider whose outer wall is slidably connected to the inner wall of a transverse fixing frame. By incorporating a compressive strength testing component, during the tensile strength testing of the PPS fiber body, a compressive strength test is required to effectively assess its strength. To adjust the compressive strength testing position on the PPS fiber body surface, the operator activates the second drive motor, causing the output shaft to rotate. This rotation of the output shaft causes the gear to rotate, meshing with a rack and causing it to move. During this movement, the rack moves the slider within the transverse fixing frame, thereby adjusting the different compressive strength testing positions on the PPS fiber body.

[0009] Preferably, a cylinder is fixedly connected to the bottom of the slider, and a compression block is fixedly connected to the output end of the cylinder. The compression block is located above the PPS fiber body. After the position for testing the compressive strength of the PPS fiber body is adjusted, the operator opens the cylinder to push the compression block downward, so that the compression block compresses the PPS fiber body, thereby realizing the compressive strength test of the PPS fiber body.

[0010] Preferably, the bottom of the rectangular frame is fixedly connected to a support leg, and there are four support legs. The four support legs are fixedly connected at equal intervals at the four corners of the bottom of the rectangular frame. By setting four support legs at the bottom of the rectangular frame, the rectangular frame can be stably supported.

[0011] Preferably, clamping blocks are provided at both ends of the top of the PPS fiber body, and the clamping blocks are used to fix the PPS fiber body during the tensile strength test.

[0012] Preferably, there are four U-shaped connecting plates, which are located on the outer walls of the four corners of the bottom of the transverse fixing frame.

[0013] This invention provides a device for testing the tensile strength of PPS fibers. This device for testing the tensile strength of PPS fibers has the following advantages:

[0014] (1) The PPS fiber tensile strength testing equipment, by setting up a tensile strength testing component, when it is necessary to test the tensile strength of the PPS fiber body, firstly, the two ends of the PPS fiber body need to be fixed. At this time, the operator places the two ends of the PPS fiber body inside the rectangular block, thereby fixing the two ends of the PPS fiber body. When testing the tensile strength of the PPS fiber body, the operator turns on the first drive motor to make the bidirectional threaded rod rotate. After the bidirectional threaded rod rotates, it will drive the first and second connecting blocks to move away from each other. After the first and second connecting blocks move away from each other, the PPS fiber body is stretched, thereby detecting the tensile strength of the PPS fiber body under the action of tension. When the two ends of the PPS fiber body enter the interior of the rectangular block, the operator rotates the adjusting block to make the screw rotate. After the screw rotates, it will cause the clamping block to move downward, so that the clamping block will squeeze the surface of the PPS fiber body, thereby clamping and fixing the two ends of the PPS fiber body.

[0015] (2) The PPS fiber tensile strength testing equipment, by setting up a compressive strength testing component, requires compressive strength testing during the tensile strength testing of the PPS fiber body. In order to effectively test the strength of the PPS fiber body, it is necessary to test its compressive strength. At this time, in order to adjust the compressive strength testing position on the surface of the PPS fiber body, the operator turns on the second drive motor to make the output shaft rotate. After the output shaft rotates, it will cause the gear to rotate. The gear will mesh with the rack, causing the rack to move. During the movement of the rack, it will drive the slider to move inside the horizontal fixed frame, thereby adjusting the different compressive strength testing positions of the PPS fiber body. After the compressive strength testing position of the PPS fiber body is adjusted, the operator turns on the cylinder to push the extrusion block downward, so that the extrusion block extrudes the PPS fiber body, thereby realizing the compressive strength testing of the PPS fiber body.

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] A preferred embodiment of the PPS fiber tensile strength testing device provided by this utility model is, for example... Figures 1 to 4 As shown: A PPS fiber tensile strength testing device includes a rectangular frame 1 and a tensile strength testing component 31 disposed above the rectangular frame 1. The tensile strength testing component 31 includes a first drive motor 311 fixedly connected to the left outer wall of the rectangular frame 1. The output end of the first drive motor 311 is fixedly connected to a bidirectional threaded rod 312. The bidirectional threaded rod 312 movably passes through the outer wall of the rectangular frame 1 and extends into the interior of the rectangular frame 1. The other end of the bidirectional threaded rod 312 is rotatably connected to the inner wall of the rectangular frame 1. A first socket block 313 is threadedly connected to the left outer wall of the bidirectional threaded rod 312, and a second socket block 314 is threadedly connected to the right outer wall of the bidirectional threaded rod 312. The bottom outer walls of the first socket block 313 and the second socket block 314 are slidably connected to the inner wall of the rectangular frame 1. A rectangular block 315 is fixedly connected to the top of the first socket block 313 and the second socket block 314 respectively. A PPS fiber body 319 is slidably connected to the bottom of the inner wall of the rectangular block 315.

[0023] By setting up the tensile strength detection component 31, when it is necessary to perform tensile strength testing on the PPS fiber body 319, the two ends of the PPS fiber body 319 first need to be fixed. At this time, the operator places the two ends of the PPS fiber body 319 inside the rectangular block 315, thereby fixing the two ends of the PPS fiber body 319. When performing tensile strength testing on the PPS fiber body 319, the operator turns on the first drive motor 311 to cause the bidirectional threaded rod 312 to rotate. After the bidirectional threaded rod 312 rotates, it will drive the first connecting block 313 and the second connecting block 314 to move away from each other. After the first connecting block 313 and the second connecting block 314 move away from each other, the PPS fiber body 319 is stretched, thereby detecting the tensile strength of the PPS fiber body 319 under tensile force.

[0024] A screw 316 is threadedly connected to the top inner wall of the rectangular block 315. An adjusting block 317 is fixedly connected to the top outer wall of the screw 316. A pressing block 318 is rotatably connected to the bottom of the screw 316. The outer wall of the pressing block 318 is slidably connected to the inner wall of the rectangular block 315. The bottom of the pressing block 318 is slidably connected to the top of the PPS fiber body 319.

[0025] After both ends of the PPS fiber body 319 enter the interior of the rectangular block 315, the operator rotates the adjusting block 317 to cause the screw 316 to rotate. After the screw 316 rotates, it will cause the clamping block 318 to move downward, so that the clamping block 318 will squeeze the surface of the PPS fiber body 319, thereby clamping and fixing both ends of the PPS fiber body 319.

[0026] A preferred embodiment of the PPS fiber tensile strength testing device provided by this utility model is, for example... Figures 1 to 4 As shown: A compressive strength testing component 32 is also provided above the rectangular frame 1. The compressive strength testing component 32 includes a U-shaped connecting plate 321 fixedly connected to the outer wall of the rectangular frame 1. A horizontal fixing frame 322 is fixedly connected to the other end of the U-shaped connecting plate 321. The horizontal fixing frame 322 is located above the rectangular frame 1. A rectangular groove 328 is opened at the top of the horizontal fixing frame 322. A support frame 323 is fixedly connected to the outer wall of the horizontal fixing frame 322. A second drive motor 324 is fixedly connected to the top inner wall of the support frame 323. An output shaft 325 is fixedly connected to the output end of the second drive motor 324. A gear 326 is fixedly connected to the outer wall of the other end of the output shaft 325. A rack 327 meshes with the bottom of the gear 326. The bottom outer wall of the rack 327 is slidably connected to the inner wall of the rectangular groove 328. A slider 329 is fixedly connected to the bottom of the rack 327. The outer wall of the slider 329 is slidably connected to the inner wall of the horizontal fixing frame 322.

[0027] By setting up the compressive strength detection component 32, during the tensile strength test of the PPS fiber body 319, in order to effectively test the strength of the PPS fiber body 319, it is necessary to perform compressive strength testing. At this time, in order to adjust the compressive strength detection position on the surface of the PPS fiber body 319, the operator turns on the second drive motor 324 to cause the output shaft 325 to rotate. After the output shaft 325 rotates, it will cause the gear 326 to rotate. The gear 326 will mesh with the rack 327, causing the rack 327 to move. During the movement of the rack 327, it will drive the slider 329 to move inside the transverse fixed frame 322, thereby adjusting the different compressive strength detection positions of the PPS fiber body 319.

[0028] A cylinder 3210 is fixedly connected to the bottom of the slider 329, and an extrusion block 3211 is fixedly connected to the output end of the cylinder 3210. The extrusion block 3211 is located above the PPS fiber body 319.

[0029] After the compressive strength test position of the PPS fiber body 319 is adjusted, the operator opens the cylinder 3210, which pushes the extrusion block 3211 downward, so that the extrusion block 3211 extrudes the PPS fiber body 319, thereby realizing the compressive strength test of the PPS fiber body 319.

[0030] Furthermore, the bottom of the rectangular frame 1 is fixedly connected with four support legs 2. The four support legs 2 are equidistantly fixed at the four corners of the bottom of the rectangular frame 1. By setting four support legs 2 at the bottom of the rectangular frame 1, the rectangular frame 1 can be stably supported.

[0031] Furthermore, clamping blocks 318 are provided at the top of both ends of the PPS fiber body 319. The clamping blocks 318 are used to fix the PPS fiber body 319 during the tensile strength test.

[0032] In addition, there are four U-shaped connecting plates 321, which are located on the outer walls of the four corners of the bottom of the horizontal fixing frame 322.

[0033] Working principle: When it is necessary to test the tensile strength of PPS fiber body 319, the two ends of PPS fiber body 319 need to be fixed first. At this time, the operator places the two ends of PPS fiber body 319 inside the rectangular block 315 to fix the two ends of PPS fiber body 319. When testing the tensile strength of PPS fiber body 319, the operator turns on the first drive motor 311 to make the bidirectional threaded rod 312 rotate. After the bidirectional threaded rod 312 rotates, it will drive the first connecting block 313 and the second connecting block 314 to move away from each other. After the first connecting block 313 and the second connecting block 314 move away from each other, the PPS fiber body 319 is stretched, so that the tensile strength of PPS fiber body 319 under the action of tensile force can be detected.

[0034] After the two ends of the PPS fiber body 319 enter the interior of the rectangular block 315, the operator rotates the adjusting block 317 to cause the screw 316 to rotate. After the screw 316 rotates, it will cause the clamping block 318 to move downward, so that the clamping block 318 will squeeze the surface of the PPS fiber body 319, thereby clamping and fixing the two ends of the PPS fiber body 319.

[0035] During the tensile strength test of PPS fiber body 319, in order to effectively test the strength of PPS fiber body 319, it is necessary to test its compressive strength. At this time, in order to adjust the compressive strength test position on the surface of PPS fiber body 319, the operator turns on the second drive motor 324 to make the output shaft 325 rotate. After the output shaft 325 rotates, it will cause the gear 326 to rotate. The gear 326 will mesh with the rack 327, causing the rack 327 to move. During the movement of the rack 327, it will drive the slider 329 to move inside the transverse fixed frame 322, thereby adjusting the different compressive strength test positions of PPS fiber body 319.

[0036] After the compressive strength test position of the PPS fiber body 319 is adjusted, the operator opens the cylinder 3210, which pushes the extrusion block 3211 downward, so that the extrusion block 3211 extrudes the PPS fiber body 319, thereby realizing the compressive strength test of the PPS fiber body 319.

[0037] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
