Description

Technical Field

[0001] The invention belongs to the technical field of fabric antistatic testing, in particular to a fabric antistatic effect testing device. Background Art

[0002] In the modern textile industry, the performance requirements of fabrics are becoming increasingly diversified and refined, among which anti-static performance has received more and more attention. With the widespread popularization of electronic devices and the deepening of people's understanding of the hazards of static electricity in daily life and work, the anti-static effect of fabrics has become a key consideration for those who often come into contact with electronic devices, are in flammable and explosive environments, or have high requirements for clothing comfort. In electronic equipment manufacturing workshops, if the work clothes worn by workers do not have good anti-static performance, the static electricity generated may break down electronic components, causing product damage and leading to high economic losses. According to statistics, electronic product failures caused by static electricity problems cause billions of dollars in losses to the global electronics manufacturing industry every year; in flammable and explosive industries such as petrochemicals and coal mines, static electricity is a potential safety hazard. Once the static electricity generated by fabrics triggers sparks, it is very likely to cause serious explosions or fire accidents, endangering the safety of life and property of enterprises; in daily life, consumers wearing clothes made of fabrics that are prone to static electricity will frequently suffer from static electricity shocks, causing discomfort, and static electricity adsorbs dust that will quickly make clothes dirty, affecting the wearing experience and aesthetics, so it is very important to test the anti-static effect of knitted fabrics.

[0003] Existing anti-static effect testing equipment for fabrics often only performs anti-static testing on the friction between fabrics and a single material. In actual applications, fabrics will rub against objects of various materials. The friction test of a single material cannot fully reflect the anti-static effect of the fabric in a complex environment. At the same time, during the test process, most of the friction tests may only be performed in one direction. In actual use, fabrics will be subjected to friction from multiple directions. This one-way test cannot fully reflect the anti-static performance of the fabric in real scenarios. Therefore, a fabric anti-static effect testing equipment is proposed. Summary of the invention

The present invention facilitates simulating airflow on the surface of fabric by arranging the coordination of structures such as airbags and spray holes. When the slider moves, it drives the baffle to squeeze one of the airbags, so that the airbag and the spring inside it are compressed, so that the internal gas is discharged from the spray hole through the ventilation groove, so that airflow is generated on the surface of the fabric. By simulating the airflow environment, the anti-static performance of the fabric can be tested more realistically, thereby more comprehensively evaluating the anti-static ability of the fabric in actual use, rather than being limited to the test results under static or no airflow conditions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides a fabric antistatic effect testing device, including a main body mechanism 3, and also includes: The friction mechanism 1 is arranged above the main mechanism 3; Among them, the friction mechanism 1 includes a motor 101, a turntable 102, a slide bar 103, a swing bar 104, a slider 105, a rotating head 106, a friction block 107, a bevel gear 108 and a baffle 109. The motor 101 is rotatably connected to the turntable 102, the turntable 102 is fixedly connected to the slide bar 103 for driving the swing bar 104 to move, the swing bar 104 is slidably sleeved on the surface of the slide bar 103, the bottom of the swing bar 104 is fixedly connected to the slide bar 105, the bottom of the slider 105 is rotatably connected to the rotating head 106, the bottom of the rotating head 106 is fixedly connected to a plurality of friction blocks 107 for rubbing against the fabric, the top of the rotating head 106 is fixedly connected to the bevel gear 108 for driving the rotating head 106 to rotate, and the top of the slider 105 is fixedly connected to two baffles 109.

[0020] The materials of the friction blocks 107 are metal, plastic and rubber respectively. The slide bar 103 is located at a position off-center from the turntable 102. The bevel gear 108 passes through the bottom of the slider 105 and extends to the top of the slider 105. The bevel gear 108 is located between the two baffles 109. The bevel gear 108 is located at the center of the top of the slider 105.

[0021] A test mechanism 2 is arranged above the main mechanism 3, and a friction mechanism 1 is arranged inside the test mechanism 2. The test mechanism 2 includes a test head 201, a rotating groove 202 is arranged inside the test head 201, a rotating shaft 203 is fixedly connected to the top of the test head 201, a slide groove 204 is arranged at the bottom of the test head 201, two air bags 205 are fixedly connected to the inner wall of the slide groove 204, a spring 211 is arranged inside the air bag 205, a ventilation groove 206 is arranged inside the test head 201, two spray holes 207 are arranged at the bottom of the test head 201, and a plurality of teeth 208 are fixedly connected to the inner wall of the slide groove 204.

[0022] The above scheme is adopted: by setting the cooperation of the swing rod 104 and the friction block 107 and other structures, it is convenient to test the anti-static effect of the friction between the fabric and different materials. The motor 101 is started to rotate the turntable 102. The rotation of the turntable 102 will drive the slide bar 103 to rotate eccentrically on the turntable 102, and exert pressure stress on the inner wall of the swing rod 104. The stress drives the swing rod 104 to rotate inside the rotating groove 202 with the rotating shaft 203 as the axis. As the slide bar 103 rotates eccentrically, it drives the swing rod 104 to rotate inside the rotating groove 202. The reciprocating motion drives the slider 105 to reciprocate at the bottom of the test head 201, so that friction is generated between the friction blocks 107 at the bottom and the fabric. The dynamic friction test between the friction blocks 107 of different materials and the fabric can simulate the contact and friction between the fabric and various different substances during actual use, so as to obtain more accurate and representative anti-static effect evaluation results. At the same time, since the friction test of multiple materials is covered, the test results can reflect the anti-static performance of the fabric in a wider range. By setting up the coordination of structures such as the bevel gear 108 and the teeth 208, it is convenient to perform multi-directional friction testing on fabrics. When the slider 105 reciprocates at the bottom of the test head 201, the bevel gear 108 moves inside the slide groove 204. Because the bevel gear 108 is meshed with the teeth 208, the bevel gear 108 is driven to rotate during the movement of the bevel gear 108, thereby driving the rotating head 106 to rotate inside the slider 105, so that the friction block 107 at the bottom thereof performs multi-directional dynamic friction on the surface of the fabric, so as to more realistically simulate the friction conditions in actual use scenarios, and can discover the anti-static performance weaknesses that may occur in the fabric under friction in a specific direction, thereby providing a more accurate basis for improving the anti-static performance of the fabric.

[0023] like Figures 2 to 8 As shown, a detection probe 209 is fixedly connected to the bottom of the test head 201, a telescopic rod 210 is fixedly connected to the bottom of the test head 201, the detection probe 209 is located between the telescopic rod 210 and the slide 204, the rotating groove 202 is located on the side of the slide 204 away from the detection probe 209, the inner wall of the airbag 205 is elastically connected to the inner wall of the slide 204 through a spring 211, the spray hole 207 is communicated with the inside of the airbag 205 through the ventilation groove 206, the two spray holes 207 are located on both sides of the slide 204, the teeth 208 are located on the side of the airbag 205 close to the detection probe 209, and the rotating shaft 203 is located inside the slide 204.

[0024] The motor 101 is fixedly connected to the inner wall of the test head 201, the turntable 102 is rotatably connected to the inner wall of the slide groove 204, the swing rod 104 is slidably connected to the rotating groove 202, the end of the swing rod 104 away from the slider 105 is rotatably connected to the rotating shaft 203, the top of the slider 105 is slidably connected to the bottom of the test head 201, the baffle 109 is slidably connected to the inner wall of the slide groove 204, the two baffles 109 are located between the two air bags 205, the bevel gear 108 is meshed with the teeth 208 on the side away from the swing rod 104, and the detection probe 209 is located on the side of the slider 105.

[0025] The main mechanism 3 includes a platform 301 , a cylinder 302 is fixedly connected to the side of the platform 301 , the bottom of the test head 201 is slidably connected to the cylinder 302 via a telescopic rod 210 , and the bottom of the detection probe 209 and the friction block 107 are against the top of the platform 301 .

[0026] A fixing mechanism 4 is provided above the main mechanism 3 and is located on the side of the testing mechanism 2. The fixing mechanism 4 includes four screws 401. A knob 402 is fixedly connected to the top of the screw 401. A pressure plate 403 is threadedly sleeved on the screw 401. The bottom of the screw 401 is rotatably connected to the top of the platform 301. There are two pressure plates 403, which are located on both sides of the top of the platform 301.

[0027] The above scheme is adopted: by setting the coordination of structures such as the airbag 205 and the nozzle hole 207, it is convenient to simulate airflow on the surface of the fabric. When the slider 105 moves, it will drive the baffle 109 to squeeze one of the airbags 205, so that the airbag 205 and the spring 211 inside it are compressed, so that the internal gas is discharged from the nozzle hole 207 through the ventilation groove 206, so that airflow is generated on the surface of the fabric. By simulating the airflow environment, the anti-static performance of the fabric can be tested more realistically, thereby more comprehensively evaluating the anti-static ability of the fabric in actual use, rather than being limited to the test results under static or no airflow conditions.

[0028] The working principle and use process of the present invention are as follows: first, the telescopic rod 210 is moved upward by the cylinder 302 and drives the test head 201 upward, and at the same time, the knob 402 is turned to rotate the screw rod 401 and drive the pressing plate 403 upward through the thread, and then the fabric is laid flat on the platform 301 and both ends of the fabric are located between the pressing plate 403 and the platform 301, and then the knob 402 is turned in the opposite direction to make the pressing plate 403 press the two ends of the fabric, and the telescopic rod 210 is moved downward by the cylinder 302, driving the bottom of the friction block 107 and the bottom of the detection probe 209 to contact the top of the fabric, and the static electricity on the fabric is detected by the detection probe 209, and the anti-static effect of the fabric is reflected by the detection data; Then, the motor 101 is started to rotate the turntable 102. The rotation of the turntable 102 drives the slide bar 103 to rotate eccentrically on the turntable 102, and applies pressure stress to the inner wall of the swing bar 104. The stress drives the swing bar 104 to rotate inside the rotating groove 202 with the rotating shaft 203 as the axis. As the slide bar 103 rotates eccentrically, the swing bar 104 is driven to reciprocate inside the rotating groove 202, thereby driving the slider 105 to reciprocate at the bottom of the test head 201, so that friction is generated between the friction blocks 107 at the bottom and the fabric. The dynamic friction test between the friction blocks 107 of different materials and the fabric can simulate the contact and friction between the fabric and various different substances during actual use. When the slider 105 reciprocates at the bottom of the test head 201, the bevel gear 108 moves inside the slide groove 204. Since the bevel gear 108 is meshed with the teeth 208, the bevel gear 108 is driven to rotate during the movement of the bevel gear 108, thereby driving the rotating head 106 to rotate inside the slider 105, so that the friction block 107 at the bottom thereof performs multi-directional dynamic friction on the surface of the fabric. At the same time, when the slider 105 moves, it will drive the baffle 109 to squeeze one of the airbags 205, so that the airbag 205 and the spring 211 inside it are compressed, so that the internal gas is discharged from the nozzle 207 through the ventilation groove 206, so that airflow is generated on the surface of the fabric. By simulating the airflow environment, the anti-static performance of the fabric can be tested more realistically.
