[0015] A method for preparing a sample for color fastness testing, the method comprising the following steps: S1. Alkaline test solution batching First, the reagents used are chemically pure. The test solution is prepared with grade tertiary water that complies with GB / T 6682. It is prepared and used immediately. Each liter of test solution contains 0.5g of L-histidine hydrochloride monohydrate (C6H9O2N3•HCl•H2O), 5.0g of sodium chloride (NaCl), and 5.0g of disodium hydrogen phosphate dodecahydrate (Na2,HPO4•12H2O). The three alkaline test solution raw materials are prepared into the required grams, and then the three raw materials are respectively placed in three storage tubes. When the preparation work is carried out, the first spur gear fixedly connected to the outer periphery of the first rotating rod is driven to rotate by the servo motor, so that the first spur gear drives the outer rack to rotate. When the outer rack rotates, it drives the second spur gear meshed on the inner side to rotate through the inner gear, so that the second spur gear drives the outer periphery of the second rotating rod to rotate. The connected quantitative plate rotates, and when the quantitative plate rotates away from the bottom of the storage tube, the raw materials can enter the mixing box through the feeding port on the top of the mixing box. When it is at the bottom of the storage tube, it can be sealed, and the unloading speed of the three storage tubes is the same, so that the raw materials in the storage tube can be quantitatively unloaded. When the second rotating rod rotates, the first transmission belt is driven to rotate through the first pulley at the same time, and the composite pulley and the third rotating rod are driven to rotate through the first transmission belt. When the composite pulley rotates, the second pulley is driven to rotate through the second transmission belt. When the second pulley rotates, it drives the fixed rod to rotate, so that the alkaline test solution ingredients can be stirred while quantitative unloading is performed; S2. Preparation of alkaline test solution When the fixed rod rotates, the stirring rod will be driven to rotate. Under the action of the stirring rod, the alkaline test solution raw materials entering the stirring box can be stirred to make the test solutions fully mixed. In the stirring process, the stirring rod can be used to drive the scraper to rotate. The test solution attached to the inner wall of the stirring box can be cleaned by the scraper to prevent the test solution from attaching and affecting the next stirring work. When the scraper is worn during long-term use, the scraper drives the moving block to slide on the first slide bar through the connecting block and squeezes the spring. When the scraper is worn and cannot contact the inner wall of the stirring box, under the elastic action of the spring, an elastic force is applied to the moving block, so that the scraper and the inner wall of the stirring box are always in contact. When the alkaline test solution is prepared, 0.1 mol / L sodium hydroxide solution is added into the stirring box through the feed port on the top of the stirring box to adjust the pH value of the test solution to 8.0 ± 0.2. S3, alkaline test solution preparation is completed and unloading is completed When unloading, just place the collecting device at the bottom of the unloading pipe, drive the sealing plate to move to the right outside the second slide rod through the cylinder, remove the insert rod from the slot, and keep the sealing plate away from the bottom of the unloading pipe, so that the alkaline test solution can be unloaded from the unloading pipe.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The sample preparation device and preparation method for color fastness detection can realize that when it is necessary to prepare the alkaline test solution for the sample, different raw materials can be stored in the storage tube according to the set weight classification through the set feeding and stirring mechanism. When it is necessary to prepare, the quantitative plate can be driven to rotate under the interaction of the first spur gear, the external rack and the second spur gear, so that the quantitative plate rotates at the bottom of the storage tube. When it is far away from the storage tube, the material can be discharged. When it is at the bottom of the storage tube, it can be sealed. The feeding speeds of the three storage tubes are the same, so that the raw materials in the storage tube can be quantitatively discharged, so as to prevent the mixing effect between the raw materials from being affected by too much feeding at one time, thereby affecting the subsequent test results. In the process of quantitative feeding, the feeding and stirring work can be in a linkage state under the interaction of the second rotating rod, the first pulley, the first transmission belt, the composite pulley, the second pulley and the second transmission belt. The feeding work can be realized under the drive of the servo motor, and the stirring rod can be driven by the fixed rod to perform stirring work, thereby improving the preparation efficiency and saving energy.

[0017] 2. The sample preparation device and preparation method for color fastness detection can realize that during the process of unloading, the fixed rod is driven to rotate through a linkage transmission mode, that is, the fixed rod is driven to rotate the stirring rod, and the alkaline test solution raw material entering the stirring box can be stirred under the action of the stirring rod to make the test solutions fully mixed, and in the process of stirring, the scraper can be driven to rotate by the stirring rod, and the test solution attached to the inner wall of the stirring box can be cleaned by the scraper to prevent the test solution from attaching and affecting the next stirring work, and when the scraper is worn during long-term use, the left side of the scraper can be always kept in contact with the inner wall of the stirring box under the action of the spring, the first sliding rod and the connecting block. The scraper is in contact with the inner wall of the mixing box to prevent the problem that the scraper cannot contact with the inner wall of the mixing box due to wear, thereby further improving the cleaning effect. The fixed rod will drive the stirring rod to rotate during the rotation of the fixed rod. The alkaline test solution raw material can be stirred by raising the stirring rod. The stirring rod will drive the protective box to rotate through the mounting plate during the rotation of the stirring rod, thereby driving the scraper to clean the test solution attached to the inner wall of the mixing box through the protective box. When the scraper is worn out after long-term use, the moving block is driven by the scraper through the connecting block to slide on the first slide bar and squeeze the spring. When the scraper is worn and cannot contact the inner wall of the mixing box, the elastic force is applied to the moving block under the elastic action of the spring, so that the scraper is always in contact with the inner wall of the mixing box.

[0018] 3. The sample preparation device and preparation method for color fastness detection can achieve a sealing effect on the bottom of the discharge pipe through the set feeding mechanism when the preparation work is carried out. At the same time, the seal on the bottom of the discharge pipe can be automatically released during the discharge work, thereby performing automatic discharge work and improving the discharge efficiency. When the preparation work is carried out, the sealing plate is driven by the cylinder to slide around the second slide bar, and during the movement, the plug rod on the left side of the sealing plate is inserted into the slot on the right side of the rectangular plate, so that the sealing plate can be moved to the bottom of the discharge pipe, and the cylinder is stopped to seal the bottom of the discharge pipe. When the discharge work is carried out, it is only necessary to drive the sealing plate to move to the right around the second slide bar again by the cylinder, and the plug rod is taken out of the slot to make the sealing plate away from the bottom of the discharge pipe, and then the discharge work can be carried out.

[0032] A method for preparing a sample for color fastness testing, the method comprising the following steps: S1. Alkaline test solution batching First, the reagents used are chemically pure. The test solution is prepared with third-grade water that complies with GB / T 6682. It is prepared and used immediately. Each liter of the test solution contains 0.5 g of L-histidine hydrochloride monohydrate (C6H9O2N3•HCl•H2O), 5.0 g of sodium chloride (NaCl), and 5.0 g of disodium hydrogen phosphate dodecahydrate (Na2,HPO4•12H2O). The three alkaline test solution raw materials are prepared into the required grams, and then the three raw materials are respectively placed in three storage tubes 413. When the preparation work is carried out, the first spur gear 416 fixedly connected to the outer periphery of the first rotating rod 417 is driven to rotate by the servo motor 415, so that the first spur gear 416 drives the outer rack 418 to rotate.

When the preparation work is carried out, the servo motor 415 drives the first spur gear 416 fixedly connected to the outer periphery of the first rotating rod 417 to rotate, so that the first spur gear 416 drives the outer rack 418 to rotate, and the outer rack When the bar 418 rotates, it will drive the second spur gear 4193 meshed inside to rotate through the internal gear 4191, so that the second spur gear 4193 drives the quantitative plate 4192 fixedly connected to the periphery of the second rotating rod 4194 to rotate. When the quantitative plate 4192 rotates away from the bottom of the storage tube 413, the raw materials can enter the mixing box 3 through the feeding port on the top of the mixing box 3. When it is at the bottom of the storage tube 413, it can be sealed, and the unloading speeds of the three storage tubes 413 are the same, so that the raw materials in the storage tube 413 can be quantitatively unloaded.

The first transmission belt 422 is driven to rotate, and the composite pulley 423 and the third rotating rod 424 are driven to rotate through the first transmission belt 422. When the composite pulley 423 rotates, the second pulley 426 is driven to rotate through the second transmission belt 425. When the second pulley 426 rotates, the fixed rod 427 is driven to rotate. When the fixed rod 427 rotates, the stirring rod 51 is driven to rotate. Under the action of the stirring rod 51, the alkaline test solution raw material entering the stirring box 3 can be stirred to fully mix the test solutions. In the process of stirring, the scraper 54 can be driven by the stirring rod 51 The scraper 54 can be rotated to clean the test solution attached to the inner wall of the mixing box 3 to prevent the test solution from attaching and affecting the next stirring work. When the scraper 54 is worn during long-term use, the scraper 54 drives the moving block 55 to slide on the first slide bar 56 through the connecting block 58, and squeezes the spring 57. When the scraper 54 is worn and cannot contact the inner wall of the mixing box 3, the elastic force is applied to the moving block 55 under the elastic action of the spring 57, so that the scraper 54 is always in contact with the inner wall of the mixing box 3. When the alkaline test solution is prepared, 0.1 mol / L sodium hydroxide solution is added into the mixing box 3 through the feed port on the top of the mixing box 3 to adjust the pH value of the test solution to 8.0 ± 0.2. When discharging, just place the collecting device at the bottom of the discharging pipe 6, drive the sealing plate 74 to move to the right outside the second slide bar 73 through the cylinder 71, remove the insert rod 75 from the slot, and keep the sealing plate 74 away from the bottom of the discharging pipe 6, so that the alkaline test solution can be discharged from the discharging pipe 6.
