Description

Technical Field

[0001] This utility model relates to the field of testing fixtures for nylon staple fibers, specifically to testing fixtures for antistatic nylon staple fibers. Background Technology

[0002] Antistatic nylon staple fiber is widely used in textiles, electronics, aerospace and other fields due to its excellent mechanical properties, antistatic properties and chemical corrosion resistance. As downstream industries continue to raise the requirements for material performance, accurately evaluating its key indicators such as antistatic properties, tensile strength and elongation at break has become the core link of quality control, which has also promoted the continuous development of testing technology.

[0003] During testing, the fixture is the core component for fixing the fiber sample, and its performance directly affects the accuracy and repeatability of the test data. Existing antistatic nylon staple fiber testing fixtures mostly adopt a fixed clamping structure, that is, the two ends of the fiber thread are rigidly fixed by bolts or buckles. Although this design can achieve the basic clamping function, it has significant defects: due to individual differences in the thickness and elasticity of the fiber thread, and the possibility of slight deformation due to the storage environment before testing, the fixed clamping method cannot freely adjust the tension of the thread. When the thread tension is too loose, the thread is prone to shaking and slipping during the test, resulting in delayed force transmission and lower tensile strength test results. If the tension is too tight, it may cause stress concentration inside the thread during the preloading stage, leading to premature breakage and a significant deviation from the actual breaking elongation. Utility Model Content

[0004] The purpose of this invention is to provide a testing fixture for antistatic nylon staple fiber, which has the advantages of quick assembly and efficient and stable tension adjustment of the filaments. It solves the problem that existing antistatic nylon staple fiber testing fixtures cannot freely adjust the tension of the fiber filaments, resulting in poor structural stability during filament testing and affecting the test results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A testing fixture for antistatic nylon staple fiber includes a wire bundle assembly, a tension adjustment assembly, and a base plate. The tension adjustment assembly is internally located within the wire bundle assembly. A base plate is located at the lower end of the wire bundle assembly. The wire bundle assembly includes a wire bundle sleeve, which is bolted to the base plate. Wire fixing nuts are located on both sides of the wire bundle sleeve, and these nuts are threadedly locked to the wire bundle sleeve. An electric push rod is internally located within the wire bundle sleeve. A lifting rod is located at the upper end of the output end of the electric push rod. A wire positioning plate is located externally to the lifting rod. A gasket is located at the upper end of the wire positioning plate. A positioning plate fixing nut is located at the upper end of the gasket, and this nut is threadedly connected to the lifting rod.

[0006] Preferably, guide grooves are provided on both sides of the thread positioning disc, and the guide grooves are integrally formed with the thread positioning disc.

[0007] It is worth noting that the guide groove improves the stability during the wire tension adjustment process.

[0008] Preferably, one end of the lifting rod is provided with a wire hole, and the wire hole is integrally formed with the lifting rod.

[0009] It is worth noting that the threading hole is used for passing through nylon staple fiber yarn, so that the lifting rod can adjust the tension of the yarn by raising and lowering it.

[0010] Preferably, the nylon staple fiber yarn is wound inside the guide groove and then passes through the threading hole.

[0011] It is worth noting that: the antistatic nylon staple fiber filament is passed through the inside of the guide groove, and finally the two ends of the antistatic nylon staple fiber filament are wrapped around the filament fixing nut, and the filament fixing nut is locked and fixed to the filament bundle sleeve, thereby fixing the two ends of the antistatic nylon staple fiber filament. At this time, the fixing operation of the antistatic nylon staple fiber filament is completed.

[0012] Preferably, the housing of the electric push rod is fixedly connected to the base plate.

[0013] It is worth noting that fixing the electric actuator to the base plate improves the overall structural stability of the base plate, the wire harness assembly, and the tension adjustment assembly, making the device more suitable for handling and fixing.

[0014] Preferably, the lower end of the wire positioning disc is provided with a limit ring, and the limit ring is integrally formed with the outer wall of the lifting rod.

[0015] It is worth noting that the limiting ring facilitates the fixation of the wire positioning plate and improves connection stability.

[0016] Preferably, the lifting rod is fixedly connected to the output end of the electric push rod.

[0017] It is worth noting that the electric push rod drives the lifting rod to rise, thereby straightening the loose antistatic nylon staple fiber filaments and adjusting the tension of the antistatic nylon staple fiber filaments. Properly tensioned antistatic nylon staple fiber filaments are beneficial for the operation of static electricity testing and greatly improve the stability of the antistatic nylon staple fiber filaments during testing.

[0018] Preferably, a test nylon staple fiber is wound between the wire harness sleeve and the wire fixing nut, and the wire fixing nut locks the two ends of the test nylon staple fiber to the wire harness sleeve.

[0019] It is worth noting that the use of gaskets, positioning plates, fixing nuts, and limit rings makes the fixed connection between the wire positioning plate and the lifting rod more stable and convenient, improving the ease of assembly and disassembly.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the arrangement of a wire harness assembly and a tension adjustment assembly, firstly, the antistatic nylon staple fiber thread is passed through the thread hole of the lifting rod, then the antistatic nylon staple fiber thread is passed through the inside of the guide groove, and finally, the two ends of the antistatic nylon staple fiber thread are wrapped around the thread fixing nut, and the thread fixing nut and the wire harness sleeve are locked and fixed, thereby fixing the two ends of the antistatic nylon staple fiber thread. At this time, the fixing operation of the antistatic nylon staple fiber thread is completed. The electric push rod drives the lifting rod to rise, thereby straightening the loose antistatic nylon staple fiber thread, and then adjusting the tension of the antistatic nylon staple fiber thread. The properly tensioned antistatic nylon staple fiber thread is beneficial to the operation of electrostatic testing and greatly improves the stability of the antistatic nylon staple fiber thread during testing.

[0021] By using gaskets, positioning plates, fixing nuts, and limit rings, the fixed connection between the wire positioning plate and the lifting rod becomes more stable and convenient, improving the ease of assembly and disassembly. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the problem of poor structural stability in existing antistatic nylon staple fiber testing fixtures, which cannot freely adjust fiber tension and thus negatively impact test results, the following technical solution is proposed. (Please refer to...) Figure 1-5 ; The testing fixture for antistatic nylon staple fiber includes a wire bundle assembly 1, a tension adjustment assembly 2, and a base plate 3. The tension adjustment assembly 2 is located inside the wire bundle assembly 1. The base plate 3 is located at the lower end of the wire bundle assembly 1. The wire bundle assembly 1 includes a wire bundle sleeve 101, which is fixedly connected to the base plate 3 by bolts. Wire fixing nuts 102 are provided on both sides of the wire bundle sleeve 101, and the wire fixing nuts 102 are threadedly locked to the wire bundle sleeve 101. An electric push rod 201 is located inside the wire bundle sleeve 101. A lifting rod 202 is located at the upper end of the output end of the electric push rod 201. A wire positioning plate 203 is located outside the lifting rod 202. A gasket 204 is located at the upper end of the wire positioning plate 203. A positioning plate fixing nut 205 is located at the upper end of the gasket 204, and the positioning plate fixing nut 205 is threadedly connected to the lifting rod 202.

[0026] The thread positioning disc 203 has guide grooves 206 on both sides, and the guide grooves 206 are integrally formed with the thread positioning disc 203.

[0027] The lifting rod 202 has a wire hole 208 inside one end, and the wire hole 208 is integrally formed with the lifting rod 202.

[0028] The nylon staple fiber yarn is wound inside the guide groove 206 and then passes through the threading hole 208.

[0029] The housing of the electric push rod 201 is fixedly connected to the base plate 3.

[0030] The lower end of the wire positioning disc 203 is provided with a limit ring 207, and the limit ring 207 is integrally formed with the outer wall of the lifting rod 202.

[0031] The lifting rod 202 is fixedly connected to the output end of the electric push rod 201.

[0032] Test nylon short fibers are wound between the cable tie sleeve 101 and the wire fixing nut 102, and the wire fixing nut 102 locks the two ends of the test nylon short fibers to the cable tie sleeve 101.

[0033] Working principle: Through the setup of the wire harness assembly 1 and the tension adjustment assembly 2, the antistatic nylon staple fiber thread is first passed through the threading hole 208 of the lifting rod 202.
