Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fabric dyeing equipment, in particular to a micro-nano antibacterial fabric dyeing device. BACKGROUND

[0002] Micro-nano antibacterial fabric is a functional fabric endowed with antibacterial function by micro-nano technology. The fabric takes into account the long-term antibacterial effect and the original characteristics of the fabric, and most of them meet the safety compliance standards. It is widely used in underwear, home textiles, medical protective clothing, sports clothing and other scenes. In the production process of micro-nano antibacterial fabric, in order to meet market demand, micro-nano antibacterial fabric needs to be dyed into different colored fabrics by dyeing equipment. For example, a patent with authorization announcement No. CN210031149U discloses a fabric dyeing machine.

[0003] At present, before the dyeing processing of micro-nano antibacterial fabric, especially after each dye is prepared, a certain specification of micro-nano antibacterial fabric sample needs to be cut for trial dyeing to determine whether the micro-nano antibacterial fabric matches the newly prepared dye. After trial dyeing, the color fastness, dyeing uniformity and other indicators of the micro-nano antibacterial fabric are checked to see if they are qualified. If all the indicators of dyeing are qualified, large-scale dyeing processing is carried out. However, the dyeing equipment in the micro-nano antibacterial fabric production factory is mainly used for large-scale production, and it is difficult to temporarily divert it to the trial dyeing link. In the trial dyeing process, the volume of micro-nano antibacterial fabric is small, so the micro-nano antibacterial fabric sample is mostly dyed by using a simple dyeing method with a stirring barrel when it is dyed with the newly prepared dye. However, in order to ensure that the micro-nano antibacterial fabric sample can be fully mixed and dyed with the dyeing liquid, a large amount of dyeing liquid needs to be prepared by using an excessive amount of dye, which is easy to cause waste of dye. At the same time, the cost of trial dyeing of the micro-nano antibacterial fabric sample is large. In addition, the speed of temperature regulation of the excessive dyeing liquid is slow, for example, it takes a long time to adjust the temperature of the dyeing liquid to the required temperature, which further affects the efficiency and convenience of the dyeing of the micro-nano antibacterial fabric.

[0004] In addition, during the trial dyeing process, as the dyeing time is prolonged, the dye in the dyeing liquid will be greatly reduced due to the continuous adsorption of the micro-nano antibacterial fabric sample. This phenomenon is more significant in the trial dyeing of micro-nano fabric. Because the specific surface area of the micro-nano antibacterial fabric sample is large, its adsorption capacity for dye is stronger, which can accelerate the decay of the concentration of the dyeing liquid. In the later stage of dyeing, the low concentration of the dyeing liquid will lead to insufficient dyeing power, and there will be obvious differences in the dye adsorption rate of different areas of the fabric sample, which will further form obvious color step differences, and finally cause uneven dyeing, which directly affects the accuracy of the trial dyeing result of the micro-nano antibacterial fabric sample.

[0005] Therefore, we propose a micro-nano antibacterial fabric dyeing device to solve the above problems. SUMMARY

[0019] Compared with the prior art, the dyeing device for micro-nano bacteriostatic fabric has the following advantages:

[0020] 1、By setting the dyeing auxiliary mechanism, concentrated dye supply mechanism and driving mechanism, when the micro-nano antibacterial fabric sample is dyed by the newly prepared dye, first place the micro-nano antibacterial fabric sample in the rotating mesh cylinder, and twist on the sealing cover to seal, then inject the appropriate amount of newly prepared dye into the dye cylinder for temporary storage, then inject the appropriate amount of pure water into the hollow base through the liquid inlet one-way valve and L-shaped pipe, then the staff sends instructions to the PLC controller through the touch panel, the PLC controller controls the dyeing auxiliary mechanism, concentrated dye supply mechanism and driving mechanism to work, realizes the dyeing operation of the micro-nano antibacterial fabric sample in the rotating mesh cylinder, the centrifugal force generated by the rotating mesh cylinder can improve the penetration effect of the dyeing liquid, and then improve the dyeing effect, in addition, the dyeing liquid enters the heat insulation cylinder and is detected by the UV-Vis online spectrum sensor, then the UV-Vis online spectrum sensor converts the dyeing concentration into an electrical signal and sends it to the PLC controller, the PLC controller adjusts the valve opening of the electromagnetic valve according to the detection result, regulates the supply of concentrated dye, ensures the dye concentration of the dyeing liquid stable, not only ensures the quality of the dyeing of the micro-nano antibacterial fabric sample, but also reduces the dyeing cost, improves the uniformity of the dyeing of the micro-nano antibacterial fabric sample, and then improves the accuracy of the dyeing result of the micro-nano antibacterial fabric sample.

[0021] 2、By setting the heating assembly, when the micro-nano antibacterial fabric sample is dyed by the dyeing liquid, the micro water pump delivers the dyeing liquid to the metal pipe, and in the process of passing through the heat shield, the electric heating pipe is controlled by the PLC controller to be electrified and work, the electric heating pipe converts electric energy into heat energy, then the heat energy is conducted through the heat conduction net block and the metal pipe to improve the temperature of the dyeing liquid, the dyeing liquid enters the heat insulation cylinder and is measured by the temperature sensor, and the measured temperature value is converted into an electrical signal and sent to the PLC controller, the PLC controller adjusts the heating power of the electric heating pipe to realize convenient regulation of the temperature of the dyeing liquid, so that a small amount of dyeing liquid is quickly heated through the metal pipe, without waiting for all the dyeing liquid in the hollow base to reach the standard temperature before dyeing, thereby effectively improving the efficiency and convenience of the dyeing of the micro-nano antibacterial fabric sample by the dyeing liquid.

[0022] 3. Through the established dye liquor impurity filtration mechanism, after the dye liquor dyes the micro-nano antibacterial fabric sample in the dyeing cylinder, the excess dye liquor is filtered through the impurity filtration mechanism and returned to the hollow base for reuse. The filter gauze layer and support mesh in the impurity filtration mechanism can effectively filter out fiber impurities adhering to the surface of the micro-nano antibacterial fabric sample mixed in with the dye liquor, avoiding the fiber impurities from clogging the micro water pump and metal pipe, ensuring the continuous and stable dyeing process of the micro-nano antibacterial fabric sample. Moreover, the returned dye liquor can be quickly restored to the concentration required for dyeing the micro-nano antibacterial fabric sample by the concentrated dye supply mechanism, so that the micro-nano antibacterial fabric sample can be dyed continuously in a dye liquor environment with the specified dye concentration. This not only ensures the uniformity of dyeing, but also reduces the consumption of concentrated dye and reduces the cost of dyeing the micro-nano antibacterial fabric sample.

[0023] 4. Through the established dyeing auxiliary and driving mechanisms, after the dyeing process is completed, the waste discharge valve is opened to drain the waste dye solution from the device. Then, pure water is continuously injected into the dye cylinder and hollow base of the device, allowing the device to operate in dyeing mode again. The pure water flows within the device, cleaning the areas through which the dye solution flows and cleaning the dye cylinder, achieving self-cleaning of the dye solution channel and preventing dye adhesion from interfering with the next dyeing operation. In addition, the pure water can also clean the dye floating on the surface of the micro-nano antibacterial fabric sample and facilitate subsequent processing of the micro-nano antibacterial fabric sample. After the micro-nano antibacterial fabric sample and the device are cleaned, the PLC controller controls the micro water pump and electric heating tube to operate, while the dual-axis motor continues to operate. The centrifugal force generated by the rotation of the rotating mesh cylinder can spin-dry the micro-nano antibacterial fabric sample, removing excess water and facilitating subsequent drying of the micro-nano antibacterial fabric sample, thus improving the efficiency of subsequent fabric drying.

[0038] The normally closed electromagnetic valve 47, the micro water pump 412, the double-shaft motor 61, the adjustable electromagnetic valve 71, the electric heating pipe 93 and the pressure relief electromagnetic valve 14 are electrically connected with the output end of the PLC controller 18 through wires, and the temperature sensor 413, the pressure sensor 13 and the UV-Vis online spectrum sensor 414 are electrically connected with the input end of the PLC controller 18 through wires, the above-mentioned powered elements and electrical connections are prior art and will not be described here.

[0039] The operation principle of the present application is described as follows: when the micro-nano antibacterial fabric sample is dyed by the newly prepared dye, first, the micro-nano antibacterial fabric sample is placed in the rotating mesh cylinder 46, and the sealing cap 3 is screwed to seal, then a proper amount of newly prepared dye is injected into the dye cylinder 72 for temporary storage, and then a proper amount of pure water is injected into the hollow base 1 through the inlet liquid check valve 12 and the L-shaped pipe 11 (the amount of pure water and newly prepared dye is proportional to the size of the micro-nano antibacterial fabric sample);

[0040] After that, the staff sends instructions to the PLC controller 18 through the touch panel 17, and the PLC controller 18 controls the micro water pump 412, the adjustable electromagnetic valve 71, the double-shaft motor 61 and the normally closed electromagnetic valve 47 to be powered on. After the adjustable electromagnetic valve 71 is powered on, it is turned on (the initial valve opening of the adjustable electromagnetic valve 71 is half of the total valve opening), so that the concentrated dye in the dye cylinder 72 flows into the pure water in the hollow base 1 under the action of gravity, so that the concentrated dye and the pure water are mixed into the dye solution required for the micro-nano antibacterial fabric sample dyeing, at the same time, the bottom driving end of the double-shaft motor 61 drives the stirring blade 64 to rotate, which can ensure that the concentrated dye and the pure water are fully mixed, then the micro water pump 412 transports the dye solution in the hollow base 1 to the hollow cylinder 43 through the metal pipe 411, and the dye solution in the hollow cylinder 43 is sprayed into the micro-nano antibacterial fabric sample through the small spray hole 44, at the same time, the top driving end of the double-shaft motor 61 drives the hollow cylinder 43 to rotate through the first bevel gear 62 and the second bevel gear 63, the hollow cylinder 43 drives the rotating mesh cylinder 46 to rotate, and the rotating mesh cylinder 46 drives the micro-nano antibacterial fabric sample to fully contact with the dye solution sprayed by the small spray hole 44, at this time, the centrifugal force of the rotating mesh cylinder 46 can improve the penetration effect of the dye solution in the micro-nano antibacterial fabric sample, thereby improving the dyeing effect;

[0041] At the same time, part of the dye solution in the hollow cylinder 43 also enters the heat insulation cylinder 41 through the communication hole 45, then the dye solution in the heat insulation cylinder 41 enters the L-shaped sealing tube 48 through the normally closed electromagnetic valve 47 powered on, and finally the dye solution in the L-shaped sealing tube 48 is sprayed out through the nozzle 49. The dye solution sprayed out of the nozzle 49 can pass through the mesh of the rotating mesh cylinder 46 to dye the micro-nano antibacterial fabric sample near the inner wall of the rotating mesh cylinder 46, so as to avoid the situation that the micro-nano antibacterial fabric sample near the inner wall of the rotating mesh cylinder 46 cannot fully contact with the dye solution with qualified concentration, thereby ensuring the dyeing effect of the micro-nano antibacterial fabric sample;

[0042] The dye solution delivered by the micro water pump 412 through the metal pipe 411 enters the heat insulation cylinder 41 and is detected by the detection end of the UV-Vis online spectrum sensor 414 to detect the concentration of the dye. At this time, the detection end of the UV-Vis online spectrum sensor 414 is completely submerged in the dye solution in the heat insulation cylinder 41, ensuring the detection effect. The UV-Vis online spectrum sensor 414 transmits ultraviolet / visible light of a specific wavelength through the dye solution by utilizing the selective absorption characteristics of dye molecules to specific wavelength light, detects the transmitted light intensity, calculates the absorbance through the ratio of "initial light intensity-transmitted light intensity", and then correlates it to the dye concentration. After that, the UV-Vis online spectrum sensor 414 converts the dyeing concentration into an electrical signal and sends it to the PLC controller 18. If the dye concentration does not reach the preset dye concentration threshold of the PLC controller 18, the PLC controller 18 controls the valve opening of the adjustable electromagnetic valve 71 to increase, increasing the supply of concentrated dye, avoiding the interference of low dye concentration of the dye solution in the hollow base 1 with the dyeing quality and affecting the dyeing efficiency. Conversely, if the dye concentration exceeds the preset dye concentration threshold of the PLC controller 18, the PLC controller 18 controls the valve opening of the adjustable electromagnetic valve 71 to decrease, reducing the supply of concentrated dye, avoiding the interference of high dye concentration of the dye solution in the hollow base 1 with the dyeing quality. By online detection of the dye concentration by the UV-Vis online spectrum sensor 414, the stability of the dye concentration can be continuously ensured, especially in the later stage of dyeing of the micro-nano antibacterial fabric sample, the dye concentration of the dye solution does not change, which not only ensures the quality of the dyeing of the micro-nano antibacterial fabric sample, but also avoids the waste caused by excessive dyeing of the dye, reduces the dyeing cost, improves the uniformity of the dyeing of the micro-nano antibacterial fabric sample, and further improves the accuracy of the dyeing result of the micro-nano antibacterial fabric sample;

[0043] When the micro-nano antibacterial fabric sample is dyed by the dye solution, the micro water pump 412 delivers the dye solution into the metal pipe 411, and in the process of passing through the heat shield 91, the electric heating pipe 93 is controlled to be powered on by the PLC controller 18. The electric heating pipe 93 converts electrical energy into heat energy, and then the heat energy is conducted through the heat-conducting mesh block 92 and the metal pipe 411 to increase the temperature of the dye solution. The temperature of the dye solution entering the heat insulation cylinder 41 is measured by the temperature sensor 413, and the measured temperature value is converted into an electrical signal and sent to the PLC controller 18. If the temperature value detected by the temperature sensor 413 does not reach the preset dye temperature threshold of the PLC controller 18, the PLC controller 18 controls the power of the electric heating pipe 93 to increase, so that more electrical energy is converted into heat energy to increase the temperature of the dye solution. Conversely, if the temperature of the dye solution is higher than the preset dye temperature threshold of the PLC controller 18, the PLC controller 18 controls the heating power of the electric heating pipe 93 to decrease, ensuring that the temperature of the dye solution meets the requirements. Moreover, a small amount of dye solution is quickly heated through the metal pipe 411, without the need to wait for the temperature of all the dye solution in the hollow base 1 to meet the requirements before dyeing, thereby effectively improving the efficiency and convenience of the dyeing of the micro-nano antibacterial fabric sample by the dye solution.

[0044] After the dyeing liquid dyes the micro-nano antibacterial fabric sample in the dyeing cylinder 2, the excess dyeing liquid is filtered by the impurity filtering mechanism 8 and then returned to the hollow base 1 for reuse. The filtering gauze layer 84 and the supporting mesh 83 in the impurity filtering mechanism 8 can effectively filter the fiber impurities attached to the surface of the micro-nano antibacterial fabric sample mixed in the dyeing liquid, avoid the fiber impurities from blocking the micro water pump 412 and the metal pipe 411, ensure the continuous and stable dyeing process of the micro-nano antibacterial fabric sample, and make the returned dyeing liquid quickly recover to the required concentration for the dyeing of the micro-nano antibacterial fabric sample through the concentrated dye supplement of the concentrated dye supply mechanism 7, so that the micro-nano antibacterial fabric sample can be continuously dyed in the dyeing liquid environment with the dye concentration meeting the regulations, which not only ensures the uniformity of the dyeing, but also reduces the consumption of the concentrated dye and the cost of the dyeing of the micro-nano antibacterial fabric sample;

[0045] In addition, after the dyeing is completed, the device can also perform cleaning work on the micro-nano antibacterial fabric sample. At this time, the PLC controller 18 controls the adjustable electromagnetic valve 71 to close and opens the waste valve 10 to discharge the unnecessary dyeing liquid in the hollow base 1. The dyeing liquid is transported to the wastewater treatment equipment for treatment through the pipeline, and pure water is continuously injected into the hollow base 1 through the L-shaped pipe 11 and the liquid inlet one-way valve 12, and the pure water is also injected into the dye cylinder 72 through the water pipe, so as to realize the cleaning of the dye cylinder 72 and the adjustable electromagnetic valve 71. Then, the pure water is extracted in the hollow base 1 by the micro water pump 412. At this time, the PLC controller 18 still controls the double-shaft motor 61, the electric heating pipe 93, and the normally closed electromagnetic valve 47 to work, so that the pure water can flush the channel through which the dyeing liquid flows, realize the self-cleaning of the dyeing liquid channel of the device, and the pure water is also sprayed out through the micro spray hole 44 and the nozzle 49 to realize the cleaning of the micro-nano antibacterial fabric sample. In addition, the electric heating pipe 93 can increase the temperature of the cleaning water, and the use of warm water can improve the cleaning effect. When the device is cleaned, the sealing plug 82 of the impurity filtering mechanism 8 is first opened, and the supporting mesh 83 and the filtering gauze layer 84 are taken out for separate cleaning, so as to ensure the cleaning effect and the reliability of the reuse of the impurity filtering mechanism 8;

[0046] After the micro-nano antibacterial fabric sample and the device are cleaned, the PLC controller 18 controls the micro water pump 412 and the electric heating pipe 93 to work, and the double-shaft motor 61 still works. The double-shaft motor 61 rotates the hollow cylinder 43 through the first helical gear 62 and the second helical gear 63, and the hollow cylinder 43 drives the rotating mesh cylinder 46 to rotate. The centrifugal force generated by the rotating mesh cylinder 46 can spin dry the micro-nano antibacterial fabric sample, remove excess water, and provide convenience for the later drying of the micro-nano antibacterial fabric sample, thereby improving the efficiency of the subsequent drying of the fabric;

[0047] In summary, the micro-nano antibacterial fabric dyeing device not only has the functions of dyeing and self-cleaning, but also has the functions of fabric floating layer dye cleaning and spin-drying, and the dyeing process does not need to pass through a large amount of dyeing liquid by excessive dyeing, reduces the dyeing cost, at the same time, the dyeing liquid temperature regulation is convenient, improves the convenience and efficiency of fabric dyeing, and the device also has the functions of online monitoring and regulation of the dye concentration in the dyeing liquid, can ensure the stability of the dye concentration in the dyeing liquid, improve the quality of the micro-nano antibacterial fabric dyeing, and ensure the accuracy of the micro-nano antibacterial fabric sample dyeing result.
