Description

Technical Field

[0001] The invention relates to the technical field of dyeing and finishing mother liquor ratio proofreading, and in particular to an automatic re-inspection machine and an automatic re-inspection method for real-time detection of dyeing and finishing mother liquor ratio. Background Art

[0002] The commonly used instruments for detecting the ratio of dyeing and finishing mother liquor generally include gas chromatography / mass spectrometry, liquid chromatography / mass spectrometry, nuclear magnetic resonance spectrometer, infrared spectrometer, gel permeation chromatography, etc. The dyeing and finishing factory batches out the mother liquor according to the ratio (formula ratio) and puts it in the mother liquor bottle so that it can be installed for dyeing. According to feedback from manufacturers, dyeing and finishing factories often trace back to the wrong process link when they find that the textiles have color differences. If it is finally found that a certain mother liquor ratio is different from the standard ratio, it means that the mother liquor of the batch that has been produced for standby has problems. The treatment method is generally to abandon environmental protection treatment, which wastes resources and is not environmentally friendly. Therefore, it is necessary to detect the mother liquor ratio in real time during the process of dyeing and preparing the mother liquor. The industry has also tried to detect it during the process of dyeing and preparing the mother liquor, but it needs to send the mother liquor to liquid chromatography / mass spectrometry and other detection instruments for additional detection after it is filled. The process is complicated and prone to errors.

[0003] Spectrophotometer is an instrument that uses spectrophotometry to conduct qualitative and quantitative analysis of substances. Spectrophotometry is a method of qualitative and quantitative analysis of substances by measuring the absorbance of light at a specific wavelength or within a certain wavelength range. It is often used as a testing equipment for food and beverage companies to apply for QS and HACCP certification, and is mainly used to analyze the proportion of food or beverages. The industry has also tried to use spectrophotometers to measure dye solutions:

[0004] For example, Chinese patent CN102706824A proposes a method for online monitoring of dye uptake of reactive dyes, the core technology of which is to measure the concentration of dye solution in real time by spectrophotometry, and calculate the real-time dye uptake by comparing it with the reference dye solution, but it does not involve detection and calibration of the mother liquor ratio.

[0005] For example, CN214115952U proposes a dyeing machine, which uses a spectrophotometer to collect color information of the object to be dyed, and the color information acquisition module 140 acquires the color information of the object to be dyed, wherein the color information to be dyed includes the color depth of the object to be dyed. The exemplary object to be dyed is a ribbon, and the color information acquisition module 140 regularly tests the color information of the ribbon, collects the color information data of the ribbon, and compares the data with the database data of the control module 110, wherein the database data includes information data such as the dyeing pressure value and the dyeing voltage value corresponding to the color information of the dyed object. When the color information data of the ribbon is within the set dye color information threshold interval, the air pressure module 120 does not adjust the air pressure; when the color information data of the ribbon is less than the set dye color information threshold interval lower limit, the pressure of the air pressure module 120 is increased according to the set pressure value to control the dyeing module 130 to reduce the amount of dye soaked in the ribbon to achieve the change of the ribbon color from dark to light; when the color information data of the ribbon is greater than the set dye color information threshold interval upper limit, the pressure of the air pressure module 120 is reduced according to the set pressure value to control the dyeing module 130 to increase the ribbon to absorb the dye and achieve the color darkening. It does not involve the detection and calibration of the mother liquor ratio.

DETAILED DESCRIPTION

[0045] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0046] Example 1. This example shows an automatic retest machine for real-time detection of dyeing and finishing mother liquor ratio, such as Figure 1-2As shown, it includes a frame 1, a manipulator 2, a controller, and an X-axis, a Y-axis, and a Z-axis arranged on the frame 1 for the manipulator 2 to move forward, backward, left, right, up, and down.

[0047] The frame 1 is also provided with a mother liquor area 3 and a stirring and mixing area 4;

[0048] The automatic retesting machine is also provided with a detection colorimetric area 5;

[0049] The mother liquid area 3 is provided with a plurality of mother liquid bottles 32 with dropper syringes 31;

[0050] The stirring and mixing zone 4 is provided with one or more liquid injection stirring devices 41 and water injection ports 44;

[0051] The water injection port 44 is connected to a water pipe, and the water pipe is connected to a flow water injection pump;

[0052] like Figure 6 As shown, if the water injection port 44 is arranged at the bottom of the liquid injection stirring device 41, water is introduced from the bottom;

[0053] like Figure 7 As shown, if the water injection port 44 is set at the mouth of the liquid injection stirring device 41, one end of the water pipe is connected to the manipulator 2, and water is injected from the mouth;

[0054] The detection colorimetric area 5 is provided with a number of colorimetric pipelines 51 corresponding to the number of the liquid injection stirring devices 41, and the front end of the colorimetric pipeline 51 is connected to the liquid injection stirring devices 41;

[0055] The colorimetric pipeline 51 is provided with a peristaltic pump 52 and a colorimetric cell 53;

[0056] The colorimetric area 5 is also provided with a spectrophotometer 54 for testing and analyzing the spectrum line of the mother solution in the cuvette 53, and the spectrophotometer 54 measures the absorbance of the mother solution in the cuvette 53;

[0057] The manipulator 2 , the liquid injection stirring device 41 , the flow injection pump, the peristaltic pump 52 and the spectrophotometer 54 are all controlled by the controller.

[0058] Working principle:

[0059] Extracting mother liquid: the controller controls the manipulator 2 to move to the mother liquid area 3 and align with the target mother liquid bottle 32, extracts a certain unit volume of mother liquid from the dropping syringe 31 corresponding to the mother liquid bottle 32, and then controls the manipulator 2 to move to the stirring and mixing area 4 and align with the target injection stirring device 41;

[0060] Dropping in the mother liquid and performing a one-step dilution: controlling the manipulator 2 to squeeze the dripping syringe 31 to drip the mother liquid into the injection stirring device 41 and injecting the solvent to fully stir and mix for a second dilution.

[0061] The solvent includes at least one of DMF and water.

[0062] During the implementation of the operation, the concentration of the diluted mother liquor is relatively high. If the mother liquor is directly measured by the spectrophotometer 54 to measure the absorbance of the mother liquor in the cuvette 53, the real data of the mother liquor ratio cannot be reflected at all. Therefore, it is necessary to inject water or DMF solvent into the liquid injection stirring device and fully stir and mix the mother liquor for a second dilution. After a long period of repeated testing and demonstration, the automatic re-inspection machine has obtained that the measurement results of the mother liquor concentration of 10PPM to 60PPM are consistent with the ratio parameter range. When the mother liquor concentration is 30PPM, the measurement result is the most stable. Among them, the mother liquor weight per unit scale volume is obtained by squeezing the drip syringe, and the flow water injection pump measures the weight of the solvent for the second dilution. It can be seen that further dilution of the mother liquor in a large proportion can ensure that the spectrophotometer measures the real ratio data.

[0063] Empty the mother liquid from the last test and clean the cuvette: The controller controls the peristaltic pump 52 in the colorimetric pipeline 51 corresponding to the target liquid injection stirring device 41, so that the mother liquid in the stirring device 41 flows through the cuvette 53 and discharges the mother liquid. The liquid flow can clean the cuvette 53 to ensure that the mother liquid from the last test does not remain in the cuvette 53, thereby ensuring the accuracy of this measurement.

[0064] Stop discharging liquid for testing: then control the peristaltic pump 52 to lock the colorimetric pipeline 51 to stop discharging the mother liquid;

[0065] Detecting the ratio parameters of the mother solution: the controller controls the spectrophotometer 54 to measure the absorbance of the mother solution in the cuvette 53 and qualitatively and quantitatively analyze the optical information of the mother solution; using a computer to calculate the ratio parameters of the obtained optical information, and compare it with the standard ratio parameters corresponding to different mother solutions stored in the computer, and feedback the comparison results;

[0066] If the current mother solution is inconsistent with the corresponding standard ratio parameters in the computer database, an error message will be prompted and the comparison result will be displayed.

[0067] In the present invention, the manipulator 2, the liquid injection stirring device 41, the flow water injection pump, the peristaltic pump 52 and the spectrophotometer 54 are all controlled by the same controller. The manipulator extracts the mother liquor, the manipulator drips the mother liquor into the liquid injection stirring device, the flow water injection pump injects the second diluted solvent into the liquid injection stirring device, the liquid injection stirring device stirs the mother liquor, the peristaltic pump controls the flow of the mother liquor in the colorimetric pipeline, and the spectrophotometer 54 measures the mother liquor in the colorimetric dish 53. The whole measurement process is automatically controlled without human intervention. The mother liquor comparison result is detected and fed back in real time. Once an error is prompted, the mother liquor preparation process is stopped in time to detect and avoid wasting resources.

[0068] Example 2. Exemplary, such as Figure 1-3As shown, there are 2-4 liquid injection and stirring devices 41, and the corresponding colorimetric pipelines 51 are 2-4. Each colorimetric pipeline 51 is provided with a corresponding peristaltic pump 52 and a cuvette 53. Each cuvette 53 is arranged on the same platform 55. A cylinder 56 is arranged on one side of the platform 55. The cylinder 56 pushes the platform 55 to align the corresponding cuvette 53 with the spectrophotometer 54 to measure the mother liquor in the corresponding cuvette 53.

[0069] Example of alternate determination of different mother liquors: If the mother liquor in mother liquor bottles No. 1-2 needs to be determined, the manipulator extracts the mother liquor in mother liquor bottle No. 1 and drips it into liquid injection stirring device No. 1, and after diluting it twice, it is fully stirred and mixed. The mother liquor detected last time is emptied in the first colorimetric pipeline 51, and the cuvette is cleaned and the liquid is stopped. The cylinder 56 pushes the platform 55 to align the corresponding cuvette 53 with the spectrophotometer 54, and the mother liquor comparison and ratio parameters are detected and the comparison results are fed back. After the manipulator drips the mother liquor into the liquid injection stirring device No. 1, the process of measuring mother liquor bottle No. 2 is directly started. The mother liquor No. 2 is dripped into the liquid injection stirring device No. 2, and after diluting it twice, it is fully stirred and mixed. The mother liquor detected last time is emptied in the second colorimetric pipeline 51, and the cuvette is cleaned and the liquid is stopped. The cylinder 56 pushes the platform 55 to align the corresponding cuvette 53 with the spectrophotometer 54, and the mother liquor comparison and ratio parameters are detected and the comparison results are fed back. Similarly, if there are mother liquid bottles No. 3-4 or even more mother liquid bottles to be tested, the operation can be performed alternately in this way, and the testing efficiency of different mother liquid bottles is high.

[0070] Example of multiple determinations of the same mother liquor: If the mother liquor in the No. 1 mother liquor bottle needs to be determined twice, the manipulator extracts the mother liquor in the No. 1 mother liquor bottle and drips it into the No. 1 liquid injection stirring device. After diluting it twice, it is fully stirred and mixed. The mother liquor detected last time is emptied in the first colorimetric pipeline 51, and the cuvette is cleaned and the liquid is stopped. The cylinder 56 pushes the platform 55 to align the corresponding cuvette 53 with the spectrophotometer 54, and the mother liquor comparison and ratio parameters are detected and the comparison results are fed back. After the manipulator drips the mother liquor into the No. 1 liquid injection stirring device, the mother liquor is directly dripped into the No. 2 liquid injection stirring device for determination. After diluting it twice, it is fully stirred and mixed. After diluting it twice, the mother liquor detected last time is emptied in the second colorimetric pipeline 51, and the cuvette is cleaned and the liquid is stopped. The cylinder 56 pushes the platform 55 to align the corresponding cuvette 53 with the spectrophotometer 54, and the mother liquor comparison and ratio parameters are detected and the comparison results are fed back. The same mother liquor is measured multiple times to see the difference in parameters twice, and the measurement results are more objective and accurate.

[0071] Example 3. Exemplary, such as Figure 4-5 As shown, the liquid injection stirring device 41 includes a stirring cup 42 and a stirring motor 43, and the stirring motor 43 is controlled by the controller.

[0076] Example 8. Exemplary, such as Figure 2-3 As shown, the end of the colorimetric pipeline 51 is also connected to a waste liquid bucket 56 .

[0080] S3: draining the mother liquid detected last time and cleaning the cuvette: the controller controls the peristaltic pump 52 in the colorimetric pipeline 51 corresponding to the target liquid injection stirring device 41, so that the mother liquid in the stirring device 41 flows through the cuvette 53 and discharges the mother liquid;
