Description

Technical Field

[0001] This utility model relates to the field of glass fiber testing technology, specifically a high-precision tensile testing device for alkali-free glass fiber yarn. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material. According to its glass composition, it can be divided into alkali-free, chemical-resistant, high-alkali, medium-alkali, high-strength, high-elastic modulus, and alkali-resistant glass fibers. Alkali-free glass fiber, also known as E-glass fiber, refers to glass fiber with low alkali metal oxide content. It has excellent chemical stability, electrical insulation properties, and strength. It is mainly used as an electrical insulation material, a reinforcing material for fiberglass, tire cord, and composite cable support.

[0003] Patent publication number "CN221594607U" discloses a tensile testing device for alkali-free glass fiber yarn. The device includes a worktable with four support legs fixedly connected to its bottom. A servo motor is fixedly installed at the bottom of the worktable, and a take-up drum is fixedly connected to the output end of the servo motor. First pulleys are fixedly installed on the outer walls of two take-up drums located in the middle and rear, and second pulleys are fixedly installed on the outer walls of two take-up drums located in the middle and front. A testing mechanism is positioned above the worktable. This alkali-free glass fiber yarn tensile testing device, with its testing mechanism, facilitates tensile testing of three strands of alkali-free glass fiber yarn at a time, increasing the amount of sample data and improving the efficiency of tensile testing. The inclusion of a dust removal mechanism cleans dust from the alkali-free glass fiber yarn before tensile testing, improving the accuracy of the test results.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1 to 4This application provides a high-precision tensile strength testing device for alkali-free glass fiber yarn, including a base plate 1, a support plate 4 fixedly installed on the top of the base plate 1, a testing component 3 provided on the top of the support plate 4, a fixing component 2 provided on the inner side of the testing component 3, the testing component 3 including a moving block 31 and a fixing block 32, the fixing block 32 being fixedly installed on the top of the support plate 4, the moving block 31 being slidably connected to the top of the support plate 4, a vertical plate 35 being fixedly installed on the top of the moving block 31, a rotating ring 36 being rotatably connected inside the vertical plate 35, and the fixing component 2 including a rotating block 21 being fixedly installed on the inner end of the corresponding rotating ring 36.

[0026] A hydraulic rod 33 is fixedly installed on the top of the support plate 4. A tension sensor 34 is fixedly installed between the output end of the hydraulic rod 33 and the right side of the moving block 31. A sliding groove 22 is provided inside the rotating block 21. A movable clamping block 24 is slidably connected inside the sliding groove 22. A fixed clamping block 23 is fixedly installed inside the sliding groove 22. A positioning groove 27 is provided between the movable clamping block 24 and the fixed clamping block 23. A screw 25 is rotatably connected to the top of the movable clamping block 24. The screw 25 is screwed through the interior of the rotating block 21. A knob 26 is fixedly installed on the top of the screw 25 and on the outside of the rotating block 21.

[0027] In this embodiment, when testing the glass fiber, the glass fiber is passed through the interior of the corresponding rotating block 21, and through the movable clamping block 24 and the fixed clamping block 23. Then, the screw 25 is rotated by rotating the knob 26. The rotation of the screw 25 can drive the movable clamping block 24 to move up and down along the slide groove 22. The movable clamping block 24 clamps the glass fiber on the outside to achieve clamping and fixing of the glass fiber. Then, the hydraulic rod 33 is activated to drive the moving block 31 to move. The moving block 31 moves in conjunction with the fixed block 32 to stretch the glass fiber. The tensile data is detected by the tensile sensor 34 to achieve the tensile strength test of the glass fiber.

[0028] Reference Figures 1 to 4 In one aspect of this embodiment, a gear ring 37 is fixedly mounted on the outer side of the rotating ring 36, and a motor 39 is fixedly mounted on the top of both the moving block 31 and the fixed block 32. A gear 38 is fixedly mounted on the output end of the motor 39, and the gear 38 meshes with the corresponding gear ring 37. The motor 39 is a self-locking motor, and two rotating blocks 21 are provided on the top of each support plate 4.

[0029] In this embodiment, before testing, the motor 39 is started, which drives the gear 38 to rotate. The rotation of the gear 38 drives the gear ring 37 to rotate, which in turn drives the rotating ring 36 and the rotating block 21 to rotate. By rotating the two motors 39 in different directions, the two rotating blocks 21 rotate in opposite directions. The glass fiber can be twisted by the reverse rotation of the rotating blocks 21. After the glass fiber is twisted, it is stretched by the moving block 31. The tensile properties of the twisted glass fiber can be tested, thus ensuring the diversity of testing.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle:

[0032] The glass fiber is passed through the corresponding rotating block 21 and through the movable clamping block 24 and the fixed clamping block 23. The knob 26 is rotated, which drives the screw 25 to rotate. The rotation of the screw 25 drives the movable clamping block 24 to move up and down along the slide groove 22. The movable clamping block 24 clamps the outside of the glass fiber, thereby clamping and fixing the glass fiber.

[0033] Start motor 39, motor 39 drives gear 38 to rotate, gear 38 drives gear ring 37 to rotate, gear ring 37 drives rotating ring 36 and rotating block 21 to rotate. The two motors 39 rotate in different directions, so that the two rotating blocks 21 rotate in opposite directions, thereby twisting the glass fiber.

[0034] Start the hydraulic rod 33, which drives the moving block 31 to move. The moving block 31 moves in conjunction with the fixed block 32 to stretch the glass fiber. The tension sensor 34 detects the tension data to realize the detection of the tensile strength of the glass fiber.
