In daily life and production process, the antistatic performance of fabric is one of the important parameters for measuring the quality of fabric. Therefore, in the production process, the antistatic performance testing device of fabric is usually used to test the antistatic performance of fabric. In the related technology, the fabric to be tested is placed on the surface of the antistatic performance testing device, and the fabric is shocked by high-voltage static electricity. After the shock is completed, the antistatic performance of the fabric is evaluated by observing the change of the static field on the surface of the fabric. However, in the process of use, the antistatic performance can only be used to test the antistatic performance of the fabric in the flat state.

[0056] Step S1: installation, placing the fabric in the fabric antistatic property testing device.

[0059] Step S4: testing, testing the change of the electrostatic field of the fabric by the fabric antistatic property testing device.

[0060] ​The anti-static performance testing method of the fabric provided in the application can test the anti-static performance of the fabric under three different tension modes, and can more comprehensively and accurately test the anti-static performance of the fabric compared with the related art.

[0061] The application further provides an anti-static performance testing device of fabric, which comprises a base 1, a rotating platform 2, a fabric adjusting mechanism 3, an electric shock mechanism 4 and an induction mechanism 5. The rotating platform 2 is installed on the base 1. The fabric adjusting mechanism 3 comprises an adjusting seat 31, two first driving assemblies 32, two second driving assemblies 33, two third driving assemblies 34 and two clamping assemblies 35. The adjusting seat 31 is installed on the base 1. The two first driving assemblies 32 are both installed on the adjusting seat 31. The two second driving assemblies 33 are installed on the two first driving assemblies 32 and move towards or away from each other in a first direction under the driving of the two first driving assemblies 32, and are arranged in one-to-one correspondence with the two first driving assemblies 32. The two third driving assemblies 34 are installed on the two second driving assemblies 33 and move towards or away from each other in a second direction under the driving of the two second driving assemblies 33, and are arranged in one-to-one correspondence with the two second driving assemblies 33. The two clamping assemblies 35 are installed on the two third driving assemblies 34 and rotate towards each other around the first direction under the driving of the two third driving assemblies 34, and are arranged in one-to-one correspondence with the two third driving assemblies 34. The fabric adjusting mechanism 3 is configured to switch to a first tension mode after the two first driving assemblies 32 drive the two clamping assemblies 35 to move towards or away from each other in the first direction, and is configured to switch to a second tension mode after the two second driving assemblies 33 drive the two clamping assemblies 35 to move towards or away from each other in the second direction, and is configured to switch to a third tension mode after the two third driving assemblies 34 drive the two clamping assemblies 35 to rotate towards each other around the first direction. The electric shock mechanism 4 is installed on the base 1. The induction mechanism 5 is installed on the base 1.

[0062] The anti-static performance testing device of the fabric provided in the application can be used for clamping the fabric through the two clamping assemblies 35. In the first tension mode, the two ends of the fabric can be pulled in the first direction through the two first driving assemblies 32, so as to simulate the anti-static performance of the fabric in the straightened state. In the second tension mode, one of the first driving assemblies 32 pulls one end of the fabric in the second direction, and the other second driving assembly 33 reversely pulls the other end of the fabric in the second direction, so as to simulate the anti-static performance of the fabric in the oblique tension state. In the third tension mode, one of the third driving assemblies 34 twists one end of the fabric around the first direction, and the other third driving assembly 34 reversely twists the other end of the fabric around the first direction, so as to simulate the anti-static performance of the fabric in the twisted state. In summary, under the action of the two first driving assemblies 32, the two second driving assemblies 33 and the two third driving assemblies 34, the posture of the fabric can be changed, so that the anti-static performance of the fabric in different postures, that is, the anti-static performance of the fabric under different tension conditions, can be tested. Compared with the related art which only tests the anti-static performance of the fabric in the flat state, the anti-static performance of the fabric can be more comprehensively and accurately tested.

[0063] By rotating the platform 2, the fabric can be driven to rotate around the third direction, so that the high-voltage static electricity can be uniformly shocked to each position of the fabric, and the repeated shock of the high-voltage static electricity to the same position can be prevented, so as to reduce the accuracy of the test.

[0064] In an embodiment of the application, referring to Figures 1 to 9 , the first driving assembly 32 comprises a first driving base 321, a first screw rod 322, a plurality of first guide rods 323 and a first sliding block 324. The first driving base 321 is installed on the adjusting seat 31. The first screw rod 322 is installed on the first driving base 321 and can rotate around the first direction. The plurality of first guide rods 323 are installed on the first driving base 321. The first sliding block 324 is provided through the first screw rod 322 and the plurality of first guide rods 323 and is screwed to the first screw rod 322.

[0065] In this way, the tester can drive the first sliding block 324 to move in the first direction by rotating the first screw rod 322, so as to adjust the position of the clamping assembly 35 in the first direction. When the two clamping assemblies 35 are used to clamp the fabric, the fabric can be straightened, and different sizes of fabrics can also be clamped, which helps to improve the application range of the device. Under the action of the plurality of first guide rods 323, the first sliding block 324 can be prevented from rotating with the first screw rod 322, so as to play a guiding role, so that the first sliding block 324 can only move in the first direction, which helps to improve the stability of the movement of the first sliding block 324 in the first direction.

[0066] In an embodiment of the application, referring to Figures 1 to 9The second driving assembly 33 comprises a second driving base 331, a second screw 332, a plurality of second guide rods 333 and a second sliding block 334. The second driving base 331 is installed on the first driving assembly 32. The second screw 332 is installed on the second driving base 331 and can rotate in the second direction. The plurality of second guide rods 333 are installed on the second driving base 331. The second sliding block 334 is arranged on the second screw 332 and the plurality of second guide rods 333 and is screwed on the second screw 332.

[0067] In this way, the tester can drive the second sliding block 334 to move in the second direction by rotating the second screw 332, so as to adjust the position of the clamping assembly 35 in the second direction. Under the action of the plurality of second guide rods 333, the second sliding block 334 can be prevented from rotating with the second screw 332, so as to play a guiding role and enable the second sliding block 334 to move in the second direction only, thereby helping to improve the movement stability of the second sliding block 334 in the second direction.

[0068] In an embodiment of the present application, referring to Figures 1 to 9 The third driving assembly 34 comprises a third driving base 341, a fixing seat 342, a rotating seat 343 and a driver 344. The third driving base 341 and the fixing seat 342 are both installed on the second driving assembly 33. The rotating seat 343 is installed on the fixing seat 342 and can rotate in the first direction relative to the fixing seat 342 and is configured to carry the clamping assembly 35. The driver 344 is installed on the third driving base 341 and is used to drive the rotating seat 343 to rotate in the first direction.

[0069] In this way, the tester can drive the clamping assembly 35 to rotate in the first direction by starting the driver 344, so as to adjust the angle of the clamping assembly 35. Under the action of the fixing seat 342 and the rotating seat 343, compared with directly using the driver 344 to drive the clamping assembly 35 to rotate in the related art, the gravity of the clamping assembly 35 can be prevented from acting on the output end of the driver 344 directly, so as to protect the driver 344 effectively. Moreover, under the action of the fixing seat 342, the rotating seat 343 can rotate in the first direction only, thereby helping to improve the rotation stability of the clamping assembly 35 in the rotating process.

[0070] In an embodiment of the present application, referring to Figures 1 to 9The clamping assembly 35 comprises a first clamping block 351, a plurality of locking screws 352, a second clamping block 353, a first groove 354, a second groove 355, a third clamping block 356, and a plurality of locking nuts 357. The first clamping block 351 is installed on the third driving assembly 34. The plurality of locking screws 352 are connected to the first clamping block 351. The second clamping block 353 is arranged through the plurality of locking screws 352. The first groove 354 is arranged on the first clamping block 351. The second groove 355 is arranged on the second clamping block 353. The third clamping block 356 is arranged through the plurality of locking screws 352 and located between the first clamping block 351 and the second clamping block 353, and is clamped in the first groove 354 and the second groove 355. The plurality of locking nuts 357 are screwed on the plurality of locking screws 352 and located on the side of the second clamping block 353 away from the first clamping block 351, and are arranged one-to-one corresponding to the plurality of locking nuts 357.

[0071] In this way, when the fabric is clamped, the fabric is clamped by the first clamping block 351, the second clamping block 353 and the third clamping block 356, so that the fabric can be clamped multiple times. Compared with the related art which only uses two clamping blocks, the clamping effect is better, and the fabric is not easy to fall out when the posture of the fabric is adjusted, so that the test can be carried out normally. Under the action of the first groove 354, the second groove 355 and the third clamping block 356, the fabric can be clamped in the first groove 354 and the second groove 355. Compared with directly clamping the fabric between the first clamping block 351 and the third clamping block 356, and between the second clamping block 353 and the third clamping block 356, it is helpful to further improve the clamping stability of the clamping assembly 35.

[0072] Under the action of the locking screw 352 and the locking nut 357, the tester can stably clamp the fabric on the clamping assembly 35. Moreover, under the action of the locking screw 352 and the locking nut 357, the second clamping block 353 and the third clamping block 356 can be disassembled from the first clamping block 351. The disassembly and assembly are convenient, which is convenient for maintenance and helps to improve the convenience of use.

The plug 368 is clamped between the first bearing block 364 and the second bearing block 365 and can limit the first bearing block 364 and the second bearing block 365 in the second direction. The push block 369 is connected to one end of the plug 368 and is arranged on the first bearing block 364 and protrudes from the surface of the first bearing block 364 away from the second bearing block 365. The clamping strip 367 on one of the second bearing blocks 365 is clamped in the clamping groove 366 on the other of the second bearing blocks 365.

[0074] It should be noted that in the related art, the fabric is usually directly clamped between the two clamping assemblies 35, and the fabric is in a suspended state. During the test, the tester needs to adjust the distance between the induction electrode 56 and the fabric and the distance between the discharge needle and the fabric. During the adjustment, the tester needs to first place a standard test sample on the surface of the fabric, then rotate the rotating platform 2 so that the fabric is sequentially aligned with the induction electrode 56 and the discharge needle, and then adjusts the height of the induction electrode 56 and the discharge needle so that the induction electrode 56 and the discharge needle contact the test sample. However, during the adjustment, the fabric is prone to collapse under the gravity of the test sample, resulting in deviation of the distance between the discharge needle and the fabric, and also resulting in deviation of the distance between the induction electrode 56 and the fabric, thereby causing errors in the test results of the anti-static property of the fabric.

[0075] In this way, when the distance between the fabric and the induction electrode 56 and the discharge needle is adjusted, the fabric can be supported under the action of the first bearing block 364, the second bearing block 365, and the plurality of bearing rods 361, so that the distance between the fabric and the induction electrode 56 and the discharge needle can be prevented from deviating due to the collapse of the fabric, and the accuracy of the device in testing the fabric can be further improved.

[0076] In the first tension mode, the bearing rod 361 can slide in the first through hole 358, and the first bearing block 364 and the second bearing block 365 can slide relative to the first clamping block 351, so that the bearing rod 361, the first bearing block 364, and the second bearing block 365 cannot move, which can prevent the two clamping assemblies 35 from being unable to be adjusted in the first direction, so that the clamping assembly 35 can normally tension the fabric. Moreover, in the first tension mode, compared with the case where the bearing rod 361 and the first through hole 358 are provided with only one, the plurality of bearing rods 361 and the plurality of first through holes 358 can improve the structural stability between the first bearing block 364 and the first clamping block 351, and can also improve the movement stability of the first bearing block 364 in the first direction when the first bearing block 364 slides relative to the first clamping block 351. In addition, in the first tension mode, the two second bearing blocks 365 can be clamped by the clamping groove 366 and the clamping strip 367, so that the two second bearing blocks 365 cannot be separated, and the bearing assembly 36 can avoid losing the bearing effect.

[0077] In the second tension mode, the clamping strip 367 can slide in the clamping groove 366, so that the two second bearing blocks 365 cannot move, which can prevent the two clamping assemblies 35 from being unable to be adjusted in the second direction, so that the clamping assembly 35 can normally tension the fabric. In the second tension mode, the first bearing block 364 and the second bearing block 365 can be limited in the second direction by the plug 368, so that the first bearing block 364 and the second bearing block 365 cannot slide relative to each other, and the structural stability between the first bearing block 364 and the second bearing block 365 is improved.

[0078] In the third tension mode, the plug 368 can be pulled out of the first bearing block 364 and the second bearing block 365 by the test personnel through the dial block 369, which greatly improves the convenience of use. After the plug 368 is pulled out, the bearing rod 361 can be hidden in the first through hole 358 and the second through hole 359 by the plurality of elastic structures 363 and the plurality of limiting blocks 362, so that the two first bearing blocks 364 can move away in the first direction, and the two second bearing blocks 365 can also move away in the first direction, so that the bearing rod 361, the first bearing block 364, and the second bearing block 365 do not interfere with the torsion of the fabric.

[0079] Since the diameter of the second through hole 359 is larger than that of the first through hole 358, and the limiting block 362 is located in the second through hole 359, under the action of the limiting block 362, the carrying rod 361 can be prevented from being taken out of the first through hole 358, and the structural stability between the carrying rod 361 and the first clamping block 351 is improved.

[0083] In this way, the tester can loosen the third fixing bolt 53, so that the first induction sleeve 52 can slide along the second mounting vertical rod 51, thereby coarsely adjusting the position of the induction electrode 56 in the third direction. The tester can tighten the third fixing bolt 53, so as to lock the first induction sleeve 52 on the second mounting vertical rod 51, achieving good fixing effect.

Under the action of the induction electrode 56, the static electric field change on the surface of the fabric after the electric shock can be sensed.

[0085] In this way, by loosening the fifth fixing bolt 582, the first positioning sleeve 581 can slide along the second installation vertical rod 51, so that the position of the linear bearing 585 in the third direction can be coarsely adjusted. By tightening the fifth fixing bolt 582, the first positioning sleeve 581 can be locked on the second installation vertical rod 51, and the fixing effect is good. By loosening the sixth fixing bolt 586, the linear bearing 585 can slide in the third direction, so that the position of the linear bearing 585 in the third direction can be finely adjusted.

[0086] When the rotating disc 21 drives the fabric to rotate, the rotating disc 21 can be limited by the central shaft 22 and the linear bearing 585, so that the rotating disc 21 is prevented from deviating during rotation, thereby helping to improve the stability of the rotating disc 21 during rotation.

[0087] Optionally, the rotating platform 2 further comprises a plurality of counterweights 23, and the plurality of counterweights 23 are installed on the rotating disc 21.

[0088] In this way, by the plurality of counterweights 23, the gravity of the fabric adjusting mechanism 3 on the rotating disc 21 can be balanced, and the rotating disc 21 is also prevented from deviating during rotation.

[0089] The working principle of the anti-static performance testing device of the fabric provided in the present application is as follows:

[0090] It is to be noted that the first direction above and below refers to the bidirectional direction of the shortest line between the two first driving assemblies 32, specifically the X-axis as shown in Figure 1 The second direction above and below refers to the bidirectional direction of the shortest line between the two first guide rods 323, specifically the Y-axis as shown in Figure 1 The third direction above and below refers to the bidirectional direction of the shortest line between the first driving assembly 32 and the second driving assembly 33, specifically the Z-axis as shown in Figure 1 The third direction above and below refers to the bidirectional direction of the shortest line between the first driving assembly 32 and the second driving assembly 33, specifically the Z-axis as shown in

[0091] The tester first places the fabric on the surface of the two bearing assemblies 36, and places one end of the fabric on the surface of the first clamping block 351, and places the third clamping block 356, which clamps the fabric into the first recess 354. The tester turns over the end of the fabric to turn the fabric to the side of the third clamping block 356 away from the first clamping block 351, and places the second clamping block 353 to clamp the turned fabric between the second clamping block 353 and the third clamping block 356, and the third clamping block 356 clamps the fabric into the second recess 355. The tester tightens the locking nut 357 to fix the fabric. The other end of the fabric is handled in the same way. After clamping, the tester rotates the first screw rod 322 to move the two first sliding blocks 324 away in the first direction to roughly straighten the fabric. After roughly straightening the fabric, the tester rotates the turntable 21 to align the fabric with the induction electrode 56. After aligning the induction electrode 56, the tester places the test block on the surface of the fabric and adjusts the position of the induction electrode 56 in the third direction to make the induction electrode 56 and the test block contact. The distance between the discharge needle and the fabric is adjusted in the same way as above. After adjustment, the tester switches the fabric adjusting mechanism to the first tension mode, the second tension mode or the third tension mode according to the testing requirements.

[0092] When it is needed to switch to the first tension mode, the tester can straighten the fabric by rotating the first screw 322 to move the two first sliders 324 in the first direction away from each other, so as to simulate the posture of the fabric in the straightened state. When it is needed to switch to the second tension mode, the tester can obliquely pull the fabric by rotating the second screw 332 to move the two second sliders 334 in the second direction away from each other, so as to simulate the posture of the fabric in the obliquely pulled state. When it is needed to switch to the third tension mode, the tester can move the plug 368 out of the first bearing block 364 and the second bearing block 365 by rotating the knob 369. After moving the plug 368 out, the tester pulls the two second bearing blocks 365 out of the two first bearing blocks 364. After pulling the two second bearing blocks 365 out, the two first bearing blocks 364 move in the first direction away from each other under the action of the elastic structure 363 until the first bearing block 364 and the first clamping block 351 contact. The tester starts the driver 344, and the two drivers 344 drive the two clamping assemblies 35 to rotate in the first direction towards each other, so that the two clamping assemblies 35 can twist the fabric, thereby simulating the posture of the fabric in the twisted state.
