Description

Technical Field

[0001] The present invention relates to the technical field of fiber testing equipment, and particularly to a multifunctional testing platform for fiber inspection. Background Art

[0002] Fiber is an elongated, soft substance that usually has a certain strength and toughness. Fibers can be a single filamentous structure or composed of multiple tiny fiber units. Their diameters are usually between a few micrometers and dozens of micrometers, and their lengths can range from a few millimeters to several kilometers. The characteristics of fibers enable them to withstand external forces such as stretching, bending, and friction, while also maintaining a certain shape and stability. To ensure the quality of fibers, fibers are generally tested, and thus a multifunctional testing platform for fiber inspection is required.

[0003] When fibers are used in daily life, they often rub against other objects. Multiple rubs can cause tiny parts of the fiber surface to be scratched and peeled off, resulting in wear. Existing multifunctional testing platforms for fiber inspection can perform tensile tests and wear tests, but separate tests are required. It is very difficult to conduct a wear test while performing a tensile test, so two independent tests need to be carried out, increasing the preparation work of test samples, increasing the time for fiber testing, and increasing manpower and material resources. Therefore, we propose a multifunctional testing platform for fiber inspection. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a multifunctional testing platform for fiber inspection.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A multifunctional testing platform for fiber inspection, comprising:

[0007] A test bench base, on the top of which a support plate is fixed. On the top of the support plate, an operation board is fixed. A tensile tester for collecting and displaying fiber tensile data is arranged on the operation board, and a fiber body is arranged on the hook of the tensile tester;

[0008] A wear device for performing wear resistance tests on fibers is arranged on the operation board, and a pressurizing device for adjusting the tensile force of fibers is also arranged on the operation board;

[0009] The wear device includes an electro-hydraulic rod and a sliding plate. A through groove is formed at one end of the operation plate away from the support plate. The cylinder barrel of the electro-hydraulic rod is fixed in the through groove. The sliding plate is fixed at the telescopic end of the electro-hydraulic rod. A sliding groove adapted to the sliding plate is formed in the through groove. A fixed frame is fixed at the bottom of the sliding plate. A groove is formed by inward depression in the middle of the fixed frame. A connecting shaft is fixed in the groove. A rotatable limit post is arranged on the connecting shaft. An adjusting mechanism is arranged at the bottom of the limit post. A plurality of different types of test blocks are arranged on the adjusting mechanism. By contacting the test blocks with the fiber body, the adjusting mechanism is pushed to drive the limit post to rotate around the connecting shaft, causing the test blocks to shake and performing a wear test on the fiber body.

[0010] The adjusting mechanism includes a knob rotatably installed at the bottom of the limit post. A threaded rod is fixed at the bottom of the knob. A positioning plate is screwed to the bottom of the threaded rod. Fixing plates are fixed at both ends of the positioning plate. A limit frame is fixed between the limit post and the fixing plates. A rotatable test roller is arranged between the two fixing plates. A plurality of test blocks are evenly arranged on the test roller. Slots adapted to the limit frame are formed in the fixing plates. A threaded hole adapted to the threaded rod is formed in the middle of the positioning plate. The threaded rod passes through the threaded hole and is located below the positioning plate. Both ends of the limit frame pass through the positioning plate and are inserted into the slots.

[0011] As a preferred technical solution of the present invention, movable rods are rotatably arranged at the lower half sections of the two fixing plates. A clamping block is fixed at one end of the movable rod. A clamping groove adapted to the clamping block is arranged on the side surface of one of the fixing plates. The test roller is fixed in the middle of the movable rod.

[0012] As a preferred technical solution of the present invention, wedge-shaped blocks are fixed on the plurality of test blocks. A plurality of wedge-shaped grooves adapted to the wedge-shaped blocks are formed on the test roller. The test blocks are installed on the test roller through the plurality of wedge-shaped blocks, facilitating the rapid replacement of the test blocks.

[0013] As a preferred technical solution of the present invention, a retaining disc is fixed at the bottom of the limit post. An installation hole adapted to the limit post is arranged at the top of the knob. A limit groove adapted to the retaining disc is arranged at the bottom of the installation hole. The retaining disc is limited by the limit groove to prevent the knob from separating from the limit post during rotation.

[0014] As a preferred technical solution of the present invention, the pressing device includes two fixed seats fixed on the base of the test bench. Two baffles are fixed on the tops of the two fixed seats. A plurality of detachable double-hook weights are arranged between the two baffles. The hooks of the double-hook weights are connected to the fiber body. Arc-shaped grooves adapted to the double-hook weights are arranged on one side of the two baffles facing each other. The plurality of double-hook weights are connected end to end through the hooks. The double-hook weights are limited by the arc-shaped grooves, so that the double-hook weights drive the fiber body to move vertically up and down. At the same time, the ultimate bearing capacity of the fiber body can be quickly and accurately measured by the double-hook weights, and the mass of the double-hook weights is not easily affected by external environmental factors, improving the accuracy of the measurement results.

[0015] As a preferred technical solution of the present invention, a rotating fixed pulley is arranged on the top of the operation board, and a movable pulley is arranged below the operation board. A rotatable fixed shaft is fixed in the middle of the fixed pulley. A support seat is fixed between the fixed shaft and the operation board. A first connecting rope is arranged between the fixed pulley and the movable pulley, and a second connecting rope is arranged between the movable pulley and the double-hook weight. The fixed pulley, the movable pulley and the first connecting rope form a labor-saving pulley block. One end of the first connecting rope is fixed to the bottom of the operation board. The movable pulley is arranged below the operation board, and the end of the first connecting rope away from the operation board bypasses the movable pulley, passes through the operation board and is fixed to the fixed pulley.

[0016] As a preferred technical solution of the present invention, two limit pulleys are fixed on the top of the base of the test bench. A hanging ring is arranged in the middle of the movable pulley. One end of the second connecting rope is connected to the movable pulley through the hanging ring, and the end of the second connecting rope away from the movable pulley passes through the bottoms of the two limit pulleys and is connected to the double-hook weight.

[0017] As a preferred technical solution of the present invention, a threading hole adapted to the first connecting rope is arranged in the middle of the operation board. A wear-resistant sleeve is arranged in the threading hole. A plurality of support arms are arranged between the support plate and the operation board. The wear-resistant sleeve can avoid the abrasion of the first connecting rope and the operation board, improving the service life of the first connecting rope. The support arms and the support plate and the operation board form a triangle, increasing the supporting force of the operation board and improving the stability of the device.

[0018] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0019] 1. Through the cooperation of structures such as a tensile tester, a wear device, an adjusting mechanism, a test roller, and a test block, after the test block moves to the position where the fiber body needs to be tested, the limit frame is pushed, causing the limit frame to drive the limit column to rotate around the connecting shaft, and the limit frame drives the test roller to rotate through the fixed plate. The test roller drives the test block to rotate, enabling the test block to rub against the fiber body. Thus, while performing a tensile test on the fiber body, a wear test can also be carried out, reducing the preparation work of test samples, shortening the time for fiber detection, and saving manpower and material resources.

[0020] 2. By pulling the moving rod, the moving rod drives the clamping block to move. After the clamping block moves to the outside of the clamping groove, the moving rod is rotated. The moving rod drives the test roller to rotate, and the test roller drives the test block to rotate. After the test block contacts the fiber body, the fiber body is bent. By rotating multiple test blocks in turn, a bending stress test is carried out on the fiber body, increasing the scope of fiber testing and improving the accuracy of test data.

[0021] 3. Through the end-to-end connection of multiple double-hook weights, after the hook of the first double-hook weight is fixed to the fiber body, a tensile test is carried out on the double-hook weights, and accurate and repeatable results can be obtained. These results can be compared with the data displayed by the tensile tester, and the results of the tensile tester can be calibrated. The operation is relatively simple and the cost is relatively low.

[0022] 4. One end of the second connecting rope is fixed to the hook of the last double-hook weight, and the other end of the second connecting rope far from the double-hook weight is fixed to the movable pulley. The fixed pulley is rotated, and the fixed pulley winds up the first connecting rope, causing the first connecting rope to drive the movable pulley to move upward. The movable pulley pulls the second connecting rope to move, and the second connecting rope stretches the fiber body through the double-hook weights. Thus, it is convenient for people to manually control the tensile force on the fiber body. At the same time, the labor-saving pulley block formed by the fixed pulley, the movable pulley, and the first connecting rope can reduce the tensile force required for the fixed pulley to wind up, reducing the labor intensity of workers.

By contacting the test blocks 508 with the fiber body 9, the adjusting mechanism is driven to drive the limit post 512 to rotate around the connecting shaft, causing the test blocks 508 to shake, and performing a wear test on the fiber body 9;

[0039] The adjusting mechanism includes a knob 511 rotatably installed at the bottom of the limit post 512. A threaded rod 509 is fixed to the bottom of the knob 511. A positioning plate 505 is screwed to the bottom of the threaded rod 509. Fixing plates 504 are fixed to both ends of the positioning plate 505. A limit frame 506 is fixed between the limit post 512 and the fixing plate 504. A rotatable test roller 507 is provided between the two fixing plates 504.

The threaded rod 509 passes through the threaded hole and is located below the positioning plate 505. Both ends of the limit frame 506 pass through the positioning plate 505 and are inserted into the slots.

[0040] A threading hole adapted to the first connecting rope 603 is provided in the middle of the operation board 3. A wear-resistant sleeve 8 is provided in the threading hole. A plurality of support arms 7 are provided between the support plate 2 and the operation board 3. The wear-resistant sleeve 8 can prevent the first connecting rope 603 from being worn by the operation board 3, improving the service life of the first connecting rope 603. A triangle is formed by the support arms 7, the support plate 2 and the operation board 3, increasing the supporting force of the operation board 3 and improving the stability of the device.

[0041] Wedge blocks are fixed on multiple test blocks 508, and a plurality of wedge grooves adapted to the wedge blocks are formed on the test roller 507. The test blocks 508 are mounted on the test roller 507 through the multiple wedge blocks, facilitating the quick replacement of the test blocks 508.

[0042] A retaining disk 513 is fixed to the bottom of the limit post 512, and a mounting hole adapted to the limit post 512 is provided at the top of the knob 511. A limit groove adapted to the retaining disk 513 is provided at the bottom of the mounting hole. The retaining disk 513 is limited by the limit groove to prevent the knob 511 from separating from the limit post 512 when rotating.

[0043] By adopting the above technical solutions:

[0044] During use, when a tensile test is performed on the fiber body 9, the knob 511 is rotated. The knob 511 drives the threaded rod 509 to rotate. The threaded rod 509 cooperates with the threaded hole of the positioning plate 505, and the limit frame 506 cooperates with the slot to limit the positioning plate 505, so that the positioning plate 505 moves along the outer wall of the threaded rod 509, causing the positioning plate 505 to drive the fixed plate 504 to move vertically up and down. The fixed plate 504 drives the test roller 507 to move vertically up and down, causing the test roller 507 to drive the test block 508 to move vertically up and down. After the test block 508 moves to the position where the fiber body 9 needs to be tested, the telescopic end of the electro-hydraulic rod 501 pushes the sliding plate 502 to move, causing the sliding plate 502 to drive the limit post 512 to move through the fixed frame 503. The limit post 512 drives the threaded rod 509 to move through the knob 511, causing the threaded rod 509 to drive the positioning plate 505 to move. The positioning plate 505 drives the fixed plate 504 to move, and the fixed plate 504 drives the test roller 507 to move, so that the test block 508 on the test roller 507 contacts the position of the fiber body 9 that needs to be detected. The limit frame 506 is pushed, causing the limit frame 506 to drive the limit post 512 to rotate around the connecting shaft, causing the limit frame 506 to drive the test roller 507 to rotate through the fixed plate 504. The test roller 507 drives the test block 508 to rotate, causing the test block 508 to rub against the fiber body 9 for wear testing. Thus, wear testing can be performed while performing a tensile test on the fiber body 9.

[0045] Secondly, as shown in Figure 1 、 Figure 2 and Figure 6 A rotatable moving rod 510 is provided at the lower half of the two fixed plates 504. A clamping block 514 is fixed to one end of the moving rod 510. A clamping groove adapted to the clamping block 514 is provided on the side of one of the fixed plates 504. The test roller 507 is fixed in the middle of the moving rod 510.

[0046] By adopting the above technical solutions:

[0047] During use, pull the moving rod 510. The moving rod 510 drives the clamping block 514 to move. After the clamping block 514 moves to the outside of the clamping groove, rotate the moving rod 510. The moving rod 510 drives the test roller 507 to rotate. The test roller 507 drives the test block 508 to rotate. After the test block 508 contacts the fiber body 9, the fiber body 9 is bent. By rotating multiple test blocks 508 in turn, the bending stress test of the fiber body 9 is carried out, increasing the scope of fiber testing and improving the accuracy of test data.

[0048] Again, refer to Figure 7 and Figure 8 As shown, the pressurizing device 6 includes two fixed seats 606 fixed on the test bench base 1. Two baffles 607 are fixed on the tops of the two fixed seats 606. A plurality of detachable double-hook weights 608 are arranged between the two baffles 607. The hooks of the double-hook weights 608 are connected to the fiber body 9. Arc grooves adapted to the double-hook weights 608 are arranged on one side of the two baffles 607 facing each other. A plurality of double-hook weights 608 are connected end to end through the hooks. The double-hook weights 608 are limited by the arc grooves, so that the double-hook weights 608 drive the fiber body 9 to move vertically up and down. At the same time, the ultimate bearing capacity of the fiber body 9 can be quickly and accurately measured through the double-hook weights 608, and the mass of the double-hook weights 608 is not easily affected by external environmental factors, improving the accuracy of the measurement results.

[0049] By adopting the above technical solutions:

[0050] During use, connect the plurality of double-hook weights 608 end to end. After fixing the hook of the first double-hook weight 608 to the fiber body 9, conduct a tensile test on the double-hook weights 608. Accurate and repeatable results can be obtained, which can be compared with the data displayed by the tensile tester 4, and the results of the tensile tester 4 can be calibrated. The operation is relatively simple and the cost is relatively low.

[0051] Finally, refer to Figure 7 、 Figure 8 and Figure 9 As shown, a rotating fixed pulley 601 is arranged on the top of the operation board 3, and a movable pulley 602 is arranged below the operation board 3. A rotatable fixed shaft is fixed in the middle of the fixed pulley 601. A support seat is fixed between the fixed shaft and the operation board 3. A first connecting rope 603 is arranged between the fixed pulley 601 and the movable pulley 602, and a second connecting rope 605 is arranged between the movable pulley 602 and the double-hook weight 608. The fixed pulley 601, the movable pulley 602 and the first connecting rope 603 form a labor-saving pulley block. One end of the first connecting rope 603 is fixed to the bottom of the operation board 3. The movable pulley 602 is arranged below the operation board 3, and the end of the first connecting rope 603 away from the operation board 3 bypasses the movable pulley 602, passes through the operation board 3 and is fixed to the fixed pulley 601.

[0052] At the top of the test bench base 1, two limit pulleys 604 are fixed. A lifting ring is provided in the middle of the movable pulley 602. One end of the second connecting rope 605 is connected to the movable pulley 602 through the lifting ring, and the end of the second connecting rope 605 away from the movable pulley 602 passes through the bottom of the two limit pulleys 604 and is connected to the double-hook weight 608.

[0053] By adopting the above technical solution:

[0054] During use, fix one end of the second connecting rope 605 to the hook of the last double-hook weight 608, and then fix the end of the second connecting rope 605 away from the double-hook weight 608 to the movable pulley 602. Rotate the fixed pulley 601, and the fixed pulley 601 winds up the first connecting rope 603, so that the first connecting rope 603 drives the movable pulley 602 to move upward, the movable pulley 602 pulls the second connecting rope 605 to move, and the second connecting rope 605 stretches the fiber body 9 through the double-hook weight 608, thus facilitating people to manually control the tensile force on the fiber body 9. At the same time, the labor-saving pulley block formed by the fixed pulley 601, the movable pulley 602 and the first connecting rope 603 can reduce the pulling force required when the fixed pulley 601 winds up, and reduce the labor intensity of workers.

[0055] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this.
