Description

Technical Field

[0001] The invention belongs to the field of fabric detection, in particular to a fabric color fastness testing device and a post-processing device thereof. Background Art

[0002] After the design stage of the fabric is completed and before it is put into production, it is necessary to test the fabric's wrinkle resistance, tensile strength, washing color fastness, perspiration color fastness and other properties. In addition to rubbing color fastness, most static textile color fastness test items require textiles or standard adjacent fabrics to be fully soaked in the test solution required by the relevant standards. Before each experiment, the experimenter needs to put the sample into the test solution specified in the standard and press and stir it from time to time to help the sample soak. At the same time, the sample needs to be soaked for a certain period of time to ensure that the sample is fully and evenly soaked. After the soaking is completed, the experimenter also needs to remove excess water from the soaked sample before starting the experiment. All the above steps require manual operation throughout the process. Among them, for common textile test items such as water fastness test, sweat fastness test, seawater fastness test, and saliva fastness test, the experimenter needs to place the samples neatly in the sweat rack after removing excess water from the samples. This step requires each sample to be separated by a resin plate and placed neatly in the sweat rack, which is cumbersome and time-consuming. For soaking fabrics, there are several automatic sample soaking devices in the prior art, but these devices cannot completely soak the samples after soaking some samples that have been waterproofed. The experimental results obtained are different from those obtained manually, and generally require experimenters to retest. Therefore, it cannot completely replace the experimenters to perform sample soaking operations. Since the sweat fastness test of textiles is a must-test item for wearing textiles, the laboratory has a large number of experimental samples that need to be tested every day. The laboratory needs to spend a lot of time and manpower on the pre-treatment steps of this experiment every day. Traditional testing instruments are difficult to meet the test needs and need to be improved. Summary of the invention

[0010] Preferably, the mounting plate and the base are connected via a mounting seat, the mounting seat forms a resting area for the clamping block to enter and stay, a protrusion is formed at the front end of the resting area, and a compression spring is connected between the clamping block and the mounting plate.

[0011] A fabric color fastness test device comprises a rotating table, a plurality of sample immersion devices, a sample feeding device, a post-processing device and a controller. The rotating table is provided with a placement slot for placing the plurality of sample immersion devices; the sample immersion device is arranged in the placement slot for immersing fabrics; the sample feeding device is arranged on the rotating table and can be opposite to a sample immersion device in a placement slot to feed the fabric into the sample immersion device; the post-processing device is arranged outside the rotating table and can be opposite to a sample immersion device in a placement slot to perform subsequent treatment on the soaked fabric; the controller is respectively connected to and controls the rotating table, the sample immersion device, the sample feeding device and the post-processing device to work.

[0013] Preferably, the sample immersion device includes a sample immersion box that can be opened or closed, a support table arranged in the sample immersion box for placing samples, a lifting platform that can be raised and lowered around the support table to assist in sample removal, and a immersion mechanism for immersing in the sample immersion box.

[0014] A test method for fabric color fastness test equipment, characterized in that:

[0015] (1) Stack the fabrics to be tested neatly into a sample box, and stack multiple sample boxes and place them into a sample feeding device;

[0016] (2) The rotating table rotates so that the sample introduction device is opposite to a sample immersion device;

[0017] (3) transferring the fabric to be tested in the sample box to the sample immersion device through the sample feeding device to immerse the fabric sample;

[0018] (4) After the sample injection is completed, the rotating table rotates so that the sample immersion device at the next station is opposite to the sample injection device, and the sample injection steps are repeated until all the sample immersion devices have completed the sample injection;

[0019] (5) When the sample immersion device that first injects the sample reaches the preset immersion time, the rotating table rotates to align the sample immersion device with the post-processing device, and a resin plate is placed on the support assembly;

[0020] (6) The post-processing device takes out the fabric to be tested from the sample immersion device, and after the fabric to be tested is transported to the liquid removal component via the sampling conveyor belt to remove excess immersion liquid, the fabric to be tested is clamped by the clamping component and laid flat on the resin plate, and the pushing component pushes the resin plate to fall from the resin box and stores the fabric to be tested between the two resin plates;

[0021] (7) After the post-treatment is completed, the rotating table rotates to align the sample immersion device of the next station with the post-treatment device, and step (6) is repeated until the fabrics to be tested in all the sample immersion devices have completed the post-treatment;

[0022] (8) Finally, all fabrics and resin plates to be tested are removed from the support assembly to complete the test.

[0023] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects: when in use, the soaked sample is transported into the device through the sampling conveyor belt, the excess soaking liquid of the soaked sample is removed by the liquid removal component, and then the fabric is clamped by the clamping component and laid flat on the supporting component, and then the resin plate is pushed by the pushing component to fall from the resin box and cover the fabric, and this is repeated for many times. After a sufficient number of fabric samples are collected, the fabric samples are taken out of the supporting component to perform a color fastness performance test, and the sample can be automatically taken from the device without the need for cumbersome manual operations, which greatly saves labor and has high practicality;

[0024] Under the action of the support spring, the support plate keeps the working plane of the clamping assembly unchanged, which will not affect the stacking of the fabric and the resin plate, thereby improving the stability of the device. The fixing block can be moved close to or away from the support plate so that the resin plate can enter the bracket without falling off, thereby further improving the stability of the device.

[0025] Every time the clamping assembly lays the fabric flat once, the driving member pushes the resin plate from the first moving channel into the second moving channel and falls down to cover the fabric, so that the resin plate can be covered on the fabric quickly and accurately, further saving labor;

[0026] The counter records the number of resin plates pressed into the storage portion. When the preset value in the counter is reached, the counter feeds back a signal to the controller. The controller controls the buzzer to sound an alarm to notify the tester to take out the fabric sample. At the same time, when the resin plates in the first conveying channel are used up, the block falls to the bottom of the first conveying channel. Since the thickness of the block is greater than the thickness of the resin plate, it cannot enter the second conveying channel. At this time, the driving member cannot operate. The motion sensor detects the signal and feeds back to the controller. The controller controls the buzzer to sound a buzzer to remind the tester to add resin plates.

[0027] The fabric is transferred from the sampling conveyor belt to the second transfer roller through the first transfer roller, and the fabric is clamped under the clamp block through the second transfer roller. After the clamp block clamps the fabric, the clamp block is driven by the moving part to move along the length direction of the support plate to lay the fabric flat on the support plate. The fabric can be laid flat quickly through a simple structure, which is more efficient and faster than manual work and has high practicality.

[0028] A protrusion is provided at the front end of the stop area. When the clamping block moves to the protrusion, the clamping block moves upward, the compression spring is compressed, and the clamping block releases the fabric clamped thereunder, completing the flattening of the fabric on the support plate. The structure is simple, efficient and fast.

[0029] The sample is transported to the sample immersion device through the sample feeding device, the sample immersion device immerses the fabric, and then the fabric is taken out, the liquid is removed and collected and stored through the post-processing device. A series of automated devices replace the current situation of manual error-prone and labor-intensive color fastness test of fabrics, which not only saves labor, but also improves work efficiency and has high practicality.

[0046] The sample feeding device 3 is arranged on the inner side of the rotating table 1, and can be opposite to the sample dipping device 2 in a placement groove 12, and can be moved and extended into the placement groove 12 to feed the fabric into the sample dipping device 2, and includes a support seat 31, a sample box 32, a fabric squeezing mechanism 33, a sample feeding conveyor belt 34, a delivery mechanism 35, a recovery mechanism 36 and a first driving mechanism.

[0047] The support base 31 is formed with a placement cavity 311 extending downward from the top thereof for placing the sample box 32;

[0048] The sample box 32 is arranged in the placement cavity 311, and a plurality of fabrics to be tested that need to be tested for color fastness are arranged inside the sample box 32. Specifically, the sample box 32 is in the shape of a flexible box body that is fully surrounded at the end and half-surrounded at the front, so that it is easy to bend and squeeze the fabric to be tested at the top out of the sample box 32;

[0049] The fabric squeezing mechanism 33 squeezes the sample box 32 and guides the fabric to be tested in the sample box 32 to bend and move in a direction close to the sample feeding conveyor belt 34, and includes a first squeezing wheel 331, a second squeezing wheel 332, a squeezing driving member 333 and a guiding member 334. The first squeezing wheel 331 is arranged in the support seat 31 close to the sample feeding conveyor belt 34; the second squeezing wheel 332 is staggered with the first squeezing wheel 331 and is located above the first squeezing wheel 331, and can move in a direction close to the first squeezing wheel 331. The first squeezing wheel 331 and the second squeezing wheel 332 are staggered with each other and can move in a direction close to the first squeezing wheel 331. The first extrusion wheel 332 is provided with a first guide rail 3331 and a second extrusion wheel 332, and the first drive motor 3332 is connected to the first extrusion wheel 331 and the second extrusion wheel 332, so as to drive the fabric to be tested in the sample box 32 to move along the conveying direction of the sample to be tested. The guide member 334 is bent and moved in the direction close to the sample feeding conveyor belt 34, so as to accurately take out the outermost fabric to be tested of the sample box 32. Specifically, the guide member 334 includes a guide block 3341, a first rotating brush 3342, a second rotating brush 3343 and a third rotating brush 3344. The guide block 3341 includes a first guide surface formed at one end thereof close to the first extrusion wheel 331 and extending upward, and a second guide surface is arranged at one end thereof close to the sample feeding conveyor belt 34 and extending downward close to the sample feeding conveyor belt 34; the first rotating brush 3342 is rotatably arranged at the first guide block 3341, a first rotating brush 3342, a second rotating brush 3343 and a third rotating brush 3344. The guide surface 3342 and the second guide surface are arranged between the first guide surface and the second guide surface, so that the fabric to be tested is transferred from the first guide surface to the second guide surface; the second rotating brush 3343 is arranged above the second guide surface and behind the first rotating brush 3342, and guides the fabric to be tested to enter the sample feeding conveyor belt 34 through the second guide surface. The guide member 334 can accurately guide the fabric to be tested to move from the sample box 32 to the sample feeding conveyor belt 34, and the first rotating brush 3342 and the second rotating brush 3343 make it difficult for the fabric to be tested to fold or detach from the device during the transfer process, thereby further improving the stability of the device;The third rotating brush 3344 is arranged above the first rotating brush 3342 and the second rotating brush 3343 to prevent the other fabrics to be tested except the outermost fabric to be tested from being squeezed and bent onto the first guide surface, and to prevent multiple fabrics to be tested from being transported into the sample feeding conveyor belt 34 at one time, so as to improve the accuracy of the test equipment. Specifically, when transporting the fabric to be tested, the first squeezing wheel 331 moves toward the second squeezing wheel 332 to squeeze the sample box 32, and the fabric to be tested in the sample box 32 is bent and squeezed out of the sample box, and the other fabrics to be tested except the outermost fabric are blocked by the third rotating brush 3344, and the outermost fabric to be tested is transferred to the sample feeding conveyor belt 34 through the first rotating brush 3342 and the second rotating brush 3343, and then the first squeezing wheel 331 is reset and moves toward the second squeezing wheel 332 again for subsequent sampling, and the above steps are repeated until the fabric to be tested in the sample box is transported.

[0050] The sample feeding conveyor belt 34 receives and conveys the fabric to be tested from the sample box 32. The sample feeding conveyor belt 34 includes two conveyor belts arranged opposite to each other up and down. The sample feeding conveyor belt 34 makes the fabric to be tested transported to the sample immersion device 2 smoother, which is convenient for subsequent tests.

[0051] The delivery mechanism 35 is arranged in the support seat 31 for supporting and delivering the sample box 32 to the fabric squeezing mechanism 33. The delivery mechanism 35 includes a moving block 351 movably arranged at the bottom of the placement cavity 311, a moving groove 352 extending outward from one side of the placement cavity 311 and corresponding to the moving block 351 for the front end of the sample box 32 to extend into, a supporting groove 353 arranged on the moving block 351 and corresponding to the moving groove 352 for supporting the sample box 32, and a delivery driving member 354 connected to and driving the moving block 351 to move. The delivery driving member 354 includes a delivery rack 3541 arranged at the end of the moving block 351, a delivery gear 3542 cooperating with the delivery rack 3541, and a delivery driving member 354 driving the delivery. The gear 3542 rotates to drive the delivery drive motor of the delivery rack 3542 to move back and forth. When the sample is placed, one end of the sample is supported in the support groove 353, and the other end is supported at the bottom of the placement cavity 311. Before the sample is placed, the moving block 351 drives the sample box 32 to move in the direction close to the moving groove 352 until the front end of the sample box 32 is placed in the moving groove 352. When the moving block 351 is reset, the front end of the sample box 32 loses the support of the moving block 351 and falls from the placement cavity 311 into the fabric squeezing mechanism 33. The structure is simple. The operator only needs to put the sample into the sample box 32 and neatly put it into the placement cavity 311, and the device can automatically place the sample box 32, with high work efficiency.

[0052] The recovery mechanism 36 includes a recovery chamber 361 disposed below the fabric squeezing mechanism 33 for recovering the sample box 32, and the recovery mechanism 36 includes a recovery chamber 361 disposed at the bottom of the support seat 31 and below the fabric squeezing mechanism 33 for recovering the sample box 32, and a rotating plate 362 rotatably disposed in the support seat 31 for opening or closing the recovery chamber 361. The sample box 32 is placed in the fabric squeezing mechanism 33, and its lower end is supported on the rotating plate 362. When the fabric to be tested is transported out of the sample box 32, the rotating plate 362 is opened to transport the sample box 32 out of the recovery chamber 361. The rotating plate 362 is provided with a weight sensor. When the fabric to be tested in the sample box 32 is conveyed, the weight sensor detects that the weight of the sample box 32 reaches a preset value, and feeds back a signal to the controller. The controller controls the rotating plate 362 to open and recycle the sample box 32. The sample box 32 can be accurately recycled through the weight sensor. Furthermore, the rotating table 1 is provided with a chute 14 opposite to the recycling chamber 361. The sample box 32 can slide out of the rotating table 1 through the chute 14, and is not easy to accumulate and clog.

[0053] The first driving mechanism is arranged at the bottom of the support seat 31 , driving the entire sample feeding device 3 to move along the conveying direction of the fabric sample to be tested, so that the sample feeding device 3 can move and extend into the placement groove 12 to convey the fabric to be tested to the sample immersion device 2 .

[0054] The post-processing device 4 is arranged outside the rotating table 1, and can move along the conveying direction of the fabric to be tested and can extend into the sample immersion device 2 to take out the fabric to be tested, and includes a base 41, a second driving mechanism 42, a sampling conveyor belt 43, a liquid removal mechanism 44 and a fabric storage mechanism 45.

[0055] The second driving mechanism 42 is disposed on the base 41, and can drive the entire post-processing device 4 to move along the conveying direction of the fabric to be tested, so that the post-processing device 4 extends into the placement groove 12 to take the fabric to be tested out of the sample immersion device 2;

[0056] The sampling conveyor belt 43 is arranged on the base 41 for receiving and transmitting the soaked fabric. Specifically, it also includes a sampling brush 431 rotatably arranged at the front end of the sampling conveyor belt 43. When the post-processing device 4 extends into the placement groove 12, the sampling brush 431 can remove the fabric to be tested from the support platform 23 and transport it to the sampling conveyor belt 43. Furthermore, the end of the lifting platform 24 close to the post-processing device 4 is provided with a downwardly inclined section of the inclined surface 242. Correspondingly, the bottom of the end of the sampling conveyor belt 43 opposite to the lifting platform 24 is provided with an inclined surface 242 and a matching lower pressure surface 432. When the fabric to be tested is completely soaked, the post-processing device 4 moves in a direction close to the lifting platform 24 to the lower pressure surface 432 to cooperate with the inclined surface 242, so that the lifting platform 24 moves downward, so that the sampling brush 431 contacts the fabric to be tested on the support platform 23, so that the fabric on the support platform 23 enters the sampling conveyor belt 43 through the sampling brush 431.

[0057] The liquid removal mechanism 44 is arranged at the end of the sampling conveyor belt 43 to remove the excess soaking liquid of the fabric after soaking, and includes a first liquid removal wheel 441 fixedly arranged on the base 41, and a second liquid removal wheel 442 which can move up and down and is arranged above the first liquid removal wheel 441 and opposite to it, and an adjusting screw 443 which is arranged above the second liquid removal wheel 442 and adjusts its up and down position. The gap between the two liquid removal wheels can be adjusted to adapt to the fabrics to be tested of different thicknesses, so that the fabrics to be tested have better passability and avoid the problem that the gap is too small and the fabrics to be tested are stuck therein;

[0058] The fabric storage mechanism 45 receives the fabric after liquid removal and stores it between the two resin plates, including a support assembly 451 for supporting the resin plates, a resin box 452 arranged above the support assembly 451 for stacking and storing the resin plates, a shelf 453 arranged on the base 41 for placing the resin box 452, a pushing assembly 454 connected to the resin box 452 and capable of pushing the resin plates to fall, a reminder assembly 455 arranged on the base 41 for reminding to replenish the resin plates and take out the fabric to be tested, and a clamping assembly 456 arranged on the base 41 for clamping and driving the fabric to move to the resin plate at the bottom;

[0059] The support assembly 451 includes a support plate 4511 that can be moved up and down and is arranged on the base 41 and is opposite to the resin box 452 for supporting the resin plate, a support spring 4512 connected between the base 41 and the support plate 4511, and a fixing member 4513 that is relatively arranged on both sides of the support plate 4511 and is used to clamp and fix the resin plate. The fixing member 4513 includes a column 45131 that is arranged on the base 41 and extends upward, a fixing block 45132 that can rotate in a direction close to or away from the resin support plate 4511, and a reset spring 45133 that is connected between the fixing block 45132 and the column 45131 and drives the fixing block 45132 to reset and clamp the resin plate. Under the action of the return spring 45133, the working plane of the clamping assembly 456 remains unchanged, which will not affect the stacking of the fabric and the resin plate, thereby improving the stability of the device. The fixing block 45132 can be close to or away from the support plate 4511 so that the resin plate can enter the base 41 without falling off, further improving the stability of the device. Specifically, after the resin plate falls on the fixing member 4513, a force can be applied to the resin plate to make the resin plate squeeze the fixing member 4513, and the return spring 45133 is compressed, so that the resin plate enters the support assembly 451. Specifically, the base 41 is provided with a through hole 411 for taking out the fabric to be tested and the resin plate.

[0060] The bottom of the resin box 452 is provided with an opening for the resin sheet to fall into;

[0061] The pushing assembly 454 includes a first moving channel 4541 arranged on the storage rack 453 and extending transversely and opposite to the opening, a second moving channel 4542 arranged at the bottom of the first moving channel 4541 and opposite to the support plate 4511, a moving plate 4543 movably arranged in the first moving channel 4541, and a pushing driving member 4544 driving the moving plate 4543 to move, the pushing driving member 4544 includes a pushing block 45441 that can move back and forth to push the resin plate from the first moving channel 4541 into the second moving channel 4542, a pushing rack 45442 arranged at the end of the pushing block 45441, and a pushing rack 45442 arranged at the end of the pushing block 45441. The push gear 45443 matched with 45442 and the push drive motor driving the push gear 45443 to rotate, the second moving channel 4542 is staggered with the opening part, and each time the clamping assembly 456 lays the fabric flat once, the push drive member 4544 pushes the resin plate from the first moving channel 4541 into the second moving channel 4542 and falls down to cover the fabric, so that the resin plate can be covered on the fabric quickly and accurately, further saving labor. Specifically, the moving plate 4543 is arranged at the end to squeeze the resin plate so that it always moves downward, and the thickness of the moving plate 4543 is greater than the height of the second moving channel 4542;

[0062] The reminder component 455 includes a counter arranged on the support component 451 for detecting the number of resin plates in the support component 451, a motion sensor arranged on the driving member 4544, and a buzzer arranged on the base 41. When the counter records the number of resin plates that have fallen, the buzzer sounds an alarm when the number preset in the counter is reached, notifying the tester to take out the fabric sample. At the same time, when the resin plates in the resin box 452 are used up, the moving plate 4543 falls into the bottom of the first moving channel 4541. The thickness of the moving plate 4543 is greater than the height of the second moving channel 4542, and the moving plate 4543 cannot enter the second moving channel 4542. At this time, the driving member 4544 cannot operate, and the buzzer sounds to remind the tester to add resin plates.

[0063] The clamping assembly 456 includes a clamping block 4561 that can move back and forth along the length direction of the support plate 4511, a mounting plate 4562 connected to the base 41 and located above the support plate 4511 for mounting the clamping block 4561, a first transfer roller 4563 rotatably arranged on the clamping block 4561 and located behind the liquid removal mechanism 44, a second transfer roller 4564 rotatably arranged on the clamping block 4561 and located below the first transfer roller 4563 and in contact with the support plate 4511, and a moving member 4565 that is connected to the mounting plate 4562 and drives the clamping block 4561 to move. The fabric is transferred from the sampling conveyor belt 43 to the second transfer roller 4564 through the first transfer roller 4563, and the fabric is clamped under the clamp block 4561 through the second transfer roller 4564. After the clamp block 4561 clamps the fabric, the clamp block 4561 is driven by the moving member 4565 to move along the length direction of the support plate 4511 to lay the fabric flat on the support plate 4511. At this time, the resin plate falls and covers the fabric to be tested. When the clamp block 4561 is reset, the resin plate and the fabric to be tested are pressed downward, and the fabric to be tested and the resin plate are fixed to the support plate 4513. The plate is pressed into the support assembly 451, and the fabric can be quickly laid flat through a simple structure, which is more efficient and faster than manual work and has high practicality. Specifically, the mounting plate 4562 is connected to the base 41 through a mounting seat 46, and the mounting seat 46 is formed with a stop area 461 for the clamping block 4561 to enter and stop, so as to prevent the resin plate from falling. A protrusion 462 is formed at the front end of the stop area 461, and the clamping block 4561 and the mounting plate 4562 are flexibly connected, and a compression spring 4566 is connected between the two. When the clamping block 4561 moves When it reaches the protrusion 462, the clamping block 4561 moves upward, the compression spring 4566 is compressed, and the clamping block 4561 releases the fabric clamped thereunder, completing the flattening of the fabric on the support plate 4511. The structure is simple, efficient and fast. Furthermore, the moving part 4565 includes a second guide rail 45651 arranged on the base 41 along the moving direction of the fabric to be measured, a second driving wheel 45652 arranged on the mounting plate 4562 and connected to the second guide rail 45651, and a second driving motor arranged on the mounting part to drive the second driving wheel 45652 to rotate.

[0064] The controller is respectively connected to and controls the operation of the rotating table 1, the sample immersion device 2, the sample feeding device 3, and the post-processing device 4. The weight sensor monitors the signal in the sample box 32 in real time and feeds back to the controller. When the fabric to be tested in the sample box 32 is transported, when the weight of the sample box 32 detected by the weight sensor reaches a preset value, the controller controls the rotating plate 362 to open, so as to realize the recovery of the sample box 32. The counter records the number of resin plates that fall and feeds back to the controller. When the number of resin plates in the support assembly 451 reaches a preset number, the controller controls the buzzer to sound an alarm to remind the staff to take out the fabric to be tested and the resin plates. The motion sensor monitors the movement of the driving member 4544 in real time. When the resin plates are used up, the moving plate 4543 falls into the end of the first moving channel 4541. At this time, since the thickness of the moving plate 4543 is greater than the height of the second moving channel 4542, the driving member 4544 cannot push the moving plate 4543. At this time, the controller controls the buzzer to sound a warning to remind the staff to replenish the resin plates.

[0065] The test method of this equipment is as follows:

[0066] (1) The fabric to be tested is neatly stacked in a sample box 32, and multiple sample boxes 32 are stacked and placed in the placement cavity 311;

[0067] (2) The rotating table 1 rotates to align the sample feeding device 3 with a sample immersion device 2. The controller controls the first driving member to operate so that the sample feeding device 3 extends into the placement slot 12, and controls the delivery mechanism 35 to operate so that the sample box 32 is delivered to the fabric squeezing mechanism 33. The fabric squeezing mechanism 33 squeezes the sample box 32 so that the fabric to be tested is transported from the sample feeding conveyor belt 34 to the support platform 23 of the sample immersion device 2 via the guide member 334. Until the fabric to be tested in the sample box 32 is transported, the gravity sensor detects that the weight of the sample box 32 reaches a preset value, and the rotating plate 362 is opened to recover the sample box 32.

[0068] (3) After the delivery is completed, the sample injection device 3 is reset, and the rotating table 1 rotates to the next sample injection device 2 for injection, until all sample injection devices 2 have completed the injection;

[0069] (4) The controller controls the sample immersion box 21 to close, and at the same time controls the sample immersion device 2 to work, so as to complete the immersion of the fabric to be tested;

[0070] (5) When the sample immersion device 2 that first injects the sample reaches the preset immersion time, the controller controls the rotating table 1 to rotate so that the sample immersion device 2 is opposite to the post-processing device 4, drives the pushing component 454 to push the resin plate to fall on the support plate 4511 and moves the resin plate to the fixing member 4513 through the clamping block 4561, controls the second driving mechanism 42 to drive the post-processing device 4 to extend into the placement groove 12, and the sampling brush 431 squeezes the lifting platform and transfers the fabric to be tested from the support platform 23 to the sampling conveyor belt 43 to complete the sampling;

[0071] (6) After the excess soaking liquid is squeezed out of the fabric to be tested by the liquid removal mechanism 44, the fabric to be tested is transferred to the second transfer roller 4564 through the first transfer roller 4563 and clamped between the clamp block 4561 and the support plate 4511. The moving member 4565 drives the fabric to be tested to move so that it is laid flat on the resin plate. When the clamp block 4561 moves to the protrusion 462 to release the fabric to be tested, the driving member 4544 pushes the resin plate to fall from the second moving channel 4542 and cover the fabric to be tested. Then the clamp block 4561 is reset, and the fabric to be tested and the resin plate are pressed into the support assembly 451 and fixed by the fixing member 4513.

[0072] (7) The second driving mechanism 42 drives the post-processing device 4 to reset, and the rotating table 1 rotates to the next sample immersion device 2, and the above post-processing steps are repeated until all the fabrics to be tested are taken out;

[0073] (8) Finally, all the fabrics and resin plates to be tested are taken out from the support assembly 451 to complete the test.

[0074] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope covered by the patent of the present invention.
