[0028] Please refer to Figure 1 The back of the friction color fastness instrument body 1 is fixedly connected with two limiting shafts 205, the inside of the bottom plate 202 is slidably connected to the outer surfaces of the two limiting shafts 205, the left side of the friction color fastness instrument body 1 is fixedly connected with a friction plate 209, and the outer surface of the friction plate 209 is clamped with a fixed plate 208.

[0029] Please refer to Figure 1 The outer surface of the friction color fastness instrument body 1 is fixedly connected with an extension plate 207, and the outer surface of the extension plate 207 is fixedly connected with an electromagnet 206. By providing the electromagnet 206, the electromagnet 206 can pull the bottom plate 202 to move to the right side, and provide power for the movement of the bottom plate 202.

[0030] The specific implementation of the embodiment is: when the device needs to be used, the cloth to be detected is placed on the surface of the friction plate 209, and then the fixed plate 208 is clamped on the friction plate 209, so that the cloth to be detected can be fixed, and then the friction color fastness instrument body 1 is controlled to run, the friction color fastness instrument body 1 running drives the friction ball above the cloth to be detected to move back and forth, which plays a role in rubbing the cloth. After rubbing for a few seconds, the electromagnet 206 is controlled to run, and the electromagnet 206 running will be full of magnetic force. When the electromagnet 206 moves to the left with the friction color fastness instrument body 1 friction arm and contacts the surface of the partition plate 3101, it will be pulled to the right with the bottom plate 202 under the action of the magnetic force. When the friction arm moves to the right to the limit position, the friction color fastness instrument body 1 can be controlled to stop running. At this time, the circular cylinder 201 is above the cloth to be detected. Then the first air pump 227 and the second hydraulic rod 230 are controlled to run, and the second hydraulic rod 230 pushes the circular ring 226 and the first air suction pipe 231 to move upwards until they enter the inside of one of the installation rings 219. With the continuous extension of the second hydraulic rod 230, the circular ring 226 and the first air suction pipe 231 can be pushed to move below the first storage cylinder 210. It should be understood that the first air suction pipe 231 is an extension pipe that can be extended and retracted with the operation of the second hydraulic rod 230. At this time, a large amount of cloth is stored in the first storage cylinder 210, and under the action of air pressure, the lowermost cloth will tightly adhere to the first air suction pipe 231. Then the second hydraulic rod 230 is reset to drive the lowermost cloth to move downwards. When the cloth moves to the inner bottom wall of the installation ring 219, the first air pump 227 is controlled to stop running. It should be understood that the installation ring 219 and the lowermost part of the first storage cylinder 210 are both provided with a protruding support ring to provide support for the cloth. When the cloth moves to the inside of the installation ring 219, the second stepper motor 221 is controlled to run, and the second stepper motor 221 running drives the turntable 217 to rotate by ninety degrees. It should be understood that the first stepper motor 214 does not lock the first transmission gear 215 when it stops running, so the first transmission gear 215 and the second transmission gear 213 will mesh during rotation. Then the first hydraulic rod 218 is controlled to run to push the extrusion block 216 to move downwards. It should be ensured that the first hydraulic rod 218 does not need to completely push the extrusion block 216 to the lowest point, but only needs to push the extrusion block 216 to the position where the protrusion is parallel to the bottom surface of the installation ring 219, so as to fix the cloth and prevent the cloth from shifting when it gets wet. Then the second stepper motor 221 is controlled to reverse rotate by forty-five degrees. In this process, power is transmitted to the first hydraulic rod 218, and the first hydraulic rod 218 drives the sliding block 211 to reverse rotate by forty-five degrees. Then the gear pump 225 is controlled to run, and the gear pump 225 pumps water in the constant-temperature water tank 203 to finally spray it on the cloth to make the cloth wet,The wetted dip cloth is rotated by forty-five degrees again, it should be pointed out that not all dip cloths need to be wetted, but when different temperature and humidity dynamic change analysis of dip cloths is needed, selective wetting treatment is carried out, then the first hydraulic rod 218 pushes the extrusion block 216 to descend, at this time the convex position of the extrusion block 216 can extrude the dip cloth to protrude below the mounting ring 219 and contact the surface of the detection cloth, then the first stepping motor 214 can be controlled to rotate, driving the first transmission gear 215 and the second transmission gear 213 to rotate, further driving the mounting ring 219 to rotate, and the mounting ring 219 rotates to drive the extrusion block 216 to rotate, the extrusion block 216 rotates on the surface of the circular block 220 and does not transmit power to the first hydraulic rod 218, thereby driving the dip cloth to stick and take work, when the wet dip cloth is taken, the above operation can be repeated to take the dry dip cloth, here only need to ensure that the gear pump 225 stops running, then the friction color fastness instrument body 1 pushes the bottom plate 202 to reset, and then controls the friction color fastness instrument body 1 to rub the cloth, when rubbing for a period of time, the above operation can be repeated to take the dip work.

[0032] As a further limitation of the storage mechanism 3 of the application, the storage unit 31 comprises a fixed block 3102, the bottom surface of the fixed block 3102 is fixedly connected to the upper surface of the bottom plate 202, the inner wall of the fixed block 3102 is fixedly connected with a third stepper motor 3110, the output end of the third stepper motor 3110 is fixedly connected with a rotating plate 3105, the bottom surface of the rotating plate 3105 is in contact with the upper surface of the fixed block 3102, the inside of the bottom plate 202 and the fixed block 3102 is jointly clamped with a second storage cylinder 3103, the inner bottom wall of the second storage cylinder 3103 is fixedly connected with a force spring 3109, the top end of the force spring 3109 is fixedly connected with a circular plate 3108, a plurality of identical first sealing boxes 3107 are arranged above the circular plate 3108, the upper surface of the bottom plate 202 is fixedly connected with a partition plate 3101, a plurality of identical second sealing boxes 3104 are arranged in the inside of the partition plate 3101, the inner wall of the circular cylinder 201 is rotatably connected with a rotating frame 3111, the inner wall of the rotating frame 3111 is fixedly connected with a third hydraulic rod 3112, by arranging the storage unit 31, the storage unit 31 can automatically unload and store the dipped cloth after the dipping process, in addition, the dipped cloths sampled at different time periods can be separately stored, preventing the problem of inaccurate detection effect caused by color mixing.

[0033] The specific implementation of the embodiment is that when a dipped cloth finishes the dipping work, the second stepper motor 221 is controlled to rotate counterclockwise by ninety degrees, so that the dipped cloth after the dipping work is moved to the upper side of the second storage cylinder 3103, at this time, the cloth will fall into the circular groove arranged on the surface of the rotating plate 3105, then the rotating plate 3105 will rotate counterclockwise by ninety degrees under the action of the third stepper motor 3110, until it rotates to the upper side of the second storage cylinder 3103, it should be understood here that the force spring 3109 inside the second storage cylinder 3103 is always exerting a pushing force on the circular plate 3108, therefore, the first sealing box 3107 inside the second storage cylinder 3103 is always in contact with the bottom surface of the rotating plate 3105, until the circular groove arranged on the upper surface of the rotating plate 3105 is located above the first sealing box 3107, at this time, the first sealing box 3107 will enter the circular groove, and the dipped cloth after the dipping work will also be in the first sealing box 3107, then the third stepper motor 3110 is controlled to continuously operate by ninety degrees, the rotating plate 3105 will drive the first sealing box 3107 to move to the lower side of the second sealing box 3104, at this time, the lowermost second sealing box 3104 will fall downward, until it falls to the upper side of the first sealing box 3107, then the third hydraulic rod 3112 is controlled to operate, so as to push the circular clamping block 3205 fixedly arranged on the surface of the second sealing box 3104 to be clamped into the circular clamping groove 3106 arranged above the first sealing box 3107, completing the clamping work, and the contact position between the first sealing box 3107 and the second sealing box 3104 is covered with a layer of rubber, which can achieve good sealing effect.

[0036] The specific implementation of the embodiment is that, as the third stepper motor 3110 continues to operate, the packaged first sealed box 3107 and the second sealed box 3104 come below the second air exhaust pipe 3202, then the second air pump 3207 is controlled to operate, and the air in the mounting block 3201 is exhausted through the second air exhaust pipe 3202, under the action of air pressure, the folded rubber pad 3204 can be folded upwards, and finally the air in the first sealed box 3107 and the second sealed box 3104 can be exhausted, when the air is exhausted, the third stepper motor 3110 operates to drive the first sealed box 3107 and the second sealed box 3104 to continue to rotate, at this time, the first sealed box 3107 and the second sealed box 3104 are in a negative pressure state, under the action of the negative pressure state, the folded rubber pad 3204 is in close contact with the surface of the second sealed box 3104, which can effectively prevent external air from entering the inside of the first sealed box 3107 and the second sealed box 3104, it should be understood that the diameters of the first sealed box 3107 and the second sealed box 3104 are greater than the diameter of the space in the mounting block 3201, therefore, the second air pump 3207 cannot move the first sealed box 3107 and the second sealed box 3104 upwards, thus, through continuous staining of the sample and the function of sampling and saving the sample at multiple time points, not only the sampling work can be quickly completed, but also the time sequence sample can be obtained, the evolution curve of the staining amount with the friction time is established, the fastness change value under different coloring degrees is dynamically monitored, and the problem that the single sample staining cannot effectively detect the coloring fastness information under different humidity and temperature conditions is solved.
