Description

Technical Field

[0001] This application relates to the field of liquid supply equipment technology, and in particular to a micro-liquid supply equipment for printing and dyeing. Background Technology

[0002] As a crucial link in the textile industry chain, the dyeing and printing industry plays a vital role in endowing fibers, yarns, and fabrics with color, patterns, and specific functions. Its core production processes, especially dyeing, printing, and finishing, heavily rely on the precise and dynamic addition and control of various chemical liquids (including but not limited to dyes, penetrants, leveling agents, fixing agents, pH adjusters, softeners, and functional finishing agents). The precision of these chemical liquid ratios, the stability of their supply, and the uniformity of their mixing are decisive technical factors for the successful implementation of the dyeing and printing process and for ensuring the quality of the final product. They directly and significantly affect many core quality indicators of dyed and printed products, such as color uniformity, color fastness grade, fabric feel and style, assigned special functions, and environmental compliance.

[0003] In related technologies, traditional liquid supply methods mainly rely on manual operation. Operators usually need to manually measure the required liquid using measuring cylinders, balances, or simple containers according to the process formula, and add it by pouring or scooping. The production efficiency is relatively low, and manual measurement may have errors, resulting in fluctuations in the liquid supply and affecting the consistency of dyeing. Therefore, it needs to be improved. Utility Model Content

[0004] To address the issues of low efficiency and susceptibility to errors in traditional manual liquid supply methods, this application provides a micro-liquid supply device for dyeing and printing.

[0005] The micro-liquid supply device for dyeing and printing provided in this application adopts the following technical solution:

[0006] A micro-liquid supply device for printing and dyeing includes a support frame and an integrated housing. At least two sets of metering pumps are installed on the support frame. The integrated housing is located below the support frame and is divided into several independent chambers. Each independent chamber is used to contain different reagents. The multiple sets of metering pumps correspond to several independent chambers. The input end of each metering pump is connected to the corresponding independent chamber. A metering manifold is installed at the output end of each metering pump. The outlet ends of several metering manifolds are connected to a main output manifold. A backwashing mechanism for cleaning the main output manifold is installed on the integrated housing.

[0007] Traditional liquid supply methods rely mainly on manual operation. Operators typically need to manually measure the required liquid using measuring cylinders, balances, or simple containers according to the process formula, and add it by pouring or scooping. This results in relatively low production efficiency, and manual measurement may introduce errors, leading to fluctuations in the liquid supply and affecting dyeing consistency. By adopting the above-mentioned technical solution, which includes a support frame and an integrated housing, multiple metering pumps are installed on the support frame. The integrated housing is divided into several independent chambers, with different agents contained in each independent chamber. The metering pumps are connected to the corresponding independent chambers and connected to the main output manifold through a metering manifold. At the same time, a backwashing mechanism is installed on the integrated housing.

[0008] During the textile printing and dyeing process, different agents required for textile printing and dyeing are added to the independent chambers separated by the integrated box. Each independent chamber contains a specific agent to ensure that the agents do not contaminate each other. According to the process formula requirements of textile printing and dyeing, the types and amounts of agents to be used are determined, and the metering pumps of the corresponding independent chambers are started. The metering pumps start working and extract the agents in the independent chambers according to the set flow rate and speed. The metering pumps accurately measure the extracted agents. The metered agents enter the metering manifold through the output end of the metering pumps. Different agents flow into the main output manifold after passing through their respective metering pumps and metering manifolds, and are finally delivered to the textile printing and dyeing equipment for dyeing. At the same time, after the liquid supply is completed, the backwashing mechanism is started to clean the main output manifold according to the equipment maintenance plan.

[0009] By integrating the housing, metering pump, independent chamber, and metering manifold, an integrated chemical supply is achieved, which greatly improves production efficiency, ensures the accuracy and stability of chemical addition, and guarantees the consistency of dyeing quality. At the same time, the backwashing mechanism helps maintain the main output pipe's cleaning function, which helps maintain the equipment's good operating condition and reduces the impact of chemical residues.

[0010] Optionally, the metering pump is provided with an inlet pipe at its input end, the inlet pipe being connected to a corresponding independent chamber, and a manual control valve for controlling the on / off state is provided on the inlet pipe.

[0011] By adopting the above technical solution, the metering pump is connected to an independent chamber through the inlet pipeline, and a manual control valve is installed on the inlet pipeline. Through the setting of the inlet pipeline and the manual control valve, the manual control valve provides on / off control for the drug extraction process. The valve can be flexibly opened or closed according to actual needs, accurately controlling the start and stop of drug supply, effectively avoiding abnormal drug flow due to unexpected situations, and enhancing the controllability of operation.

[0012] Optionally, the bottom of each of the independent chambers is a conical liquid collection structure, and the inlet end of the liquid inlet pipe extends to the lowest point of the conical liquid collection structure.

[0013] By adopting the above technical solution, the bottom of the independent chamber has a conical liquid collection structure, and the inlet end of the liquid inlet pipe extends to the lowest point of the conical liquid collection structure. The independent chamber structure improves the efficiency of drug utilization. The conical structure can naturally guide the drug in the chamber to converge to the lowest point, ensuring that the liquid inlet pipe can fully extract residual drugs, reducing the accumulation and waste of drugs at the bottom of the chamber, and avoiding problems such as deterioration and pollution caused by drug residues.

[0014] Optionally, the integrated enclosure is provided with an observation window on its side wall, and the surface of the observation window is engraved with a measuring scale for real-time monitoring of the liquid volume in the independent chamber.

[0015] By adopting the above technical solution, a transparent observation window is installed on the integrated housing, and a metering scale is engraved on the observation window. The setting of the observation window and the metering scale provides an intuitive means of liquid monitoring. The metering scale can provide real-time feedback on the liquid volume, which facilitates quick judgment of the remaining amount of the reagent, timely replenishment, and reduces the possibility of production being affected by insufficient reagent.

[0016] Optionally, the output end of the metering pump is provided with a flexible delivery pipe, and the two ends of the flexible delivery pipe are respectively connected to the output end of the metering pump and the metering manifold.

[0017] By adopting the above technical solution, the metering pump is connected to the metering manifold through a flexible delivery pipe; the flexible delivery pipe has good flexibility and bendability, which can effectively adapt to the spatial layout during equipment installation and reduce the installation difficulty.

[0018] Optionally, a sealing joint is provided at the connection between the flexible delivery pipe and the metering manifold.

[0019] By adopting the above technical solution, the sealing joint is installed at the connection between the flexible delivery pipe and the metering manifold. Through the setting of the sealing joint, the sealing joint can effectively fill the tiny gap at the connection between the flexible delivery pipe and the metering manifold, forming a reliable sealing barrier to prevent leakage of the agent during delivery and avoid waste of the agent.

[0020] Optionally, the backwashing mechanism includes a backwashing pipeline and a backwashing pump. The integrated housing is also provided with a clean water chamber. The input end of the backwashing pump is connected to the clean water chamber. One end of the backwashing pipeline is connected to the output end of the backwashing pump. The backwashing pipeline is connected to the end of the main output manifold.

[0021] By adopting the above technical solution, the backwashing mechanism includes a backwashing pipeline and a backwashing pump. When cleaning the main output main pipe, the clean water chamber inside the integrated box stores enough clean water. The backwashing pump is started, and its input end draws clean water from the clean water chamber. The output high-pressure clean water is transported to the end of the main output main pipe through the backwashing pipeline. After the clean water enters the main output main pipe from the end, it flushes the inner wall of the pipe, washing away residual agents, dirt and other impurities attached to the pipe wall.

[0022] The backflushing mechanism effectively removes residual chemicals and dirt adhering to the inner wall of the pipeline, ensuring that the pipeline is clean and unobstructed, avoiding problems such as blockage and corrosion caused by the accumulation of impurities, and ensuring stable subsequent liquid supply quality.

[0023] Optionally, the integrated housing is provided with a support for fixing the main output manifold, and the number of the supports is multiple, which are arranged along the length of the main output manifold.

[0024] By adopting the above technical solution, the main output manifold is installed on the support of the integrated box; the support provides multi-point support for the main output manifold, effectively dispersing the weight of the pipe itself and the stress generated during operation, thus ensuring the stability of the pipe.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By integrating the housing, metering pump, independent chamber, metering manifold, etc., integrated chemical supply is achieved, which greatly improves production efficiency, ensures the accuracy and stability of chemical addition, and guarantees the consistency of dyeing quality. At the same time, combined with the backwashing mechanism to clean the main output pipe, it helps to maintain the equipment in good operating condition and reduce the impact of chemical residue.

[0027] 2. The independent chamber structure improves the efficiency of drug utilization. The conical structure can naturally guide the drug in the chamber to converge to the lowest point, ensuring that the liquid inlet pipeline can fully extract the residual drug, reducing the accumulation and waste of the drug at the bottom of the chamber, and avoiding problems such as deterioration and pollution caused by drug residue.

[0028] 3. The backflushing mechanism effectively removes residual chemicals and dirt adhering to the inner wall of the pipeline, ensuring that the pipeline is clean and unobstructed, avoiding problems such as blockage and corrosion caused by the accumulation of impurities, and ensuring stable subsequent liquid supply quality.

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0033] This application discloses a micro-liquid supply device for printing and dyeing. (Refer to...) Figure 1 The micro-liquid supply device for printing and dyeing includes a support frame 1 and an integrated housing 2. At least two sets of metering pumps 3 are installed on the support frame 1. In this embodiment, it is preferred that the number of metering pumps 3 is four sets, and the four sets of metering pumps 3 are arranged in sequence on the support frame 1.

[0034] Reference Figure 1 and Figure 2 The integrated housing 2 is arranged below the support frame 1. The integrated housing 2 is divided into several independent chambers 4. In this embodiment, the number of independent chambers 4 is the same as the number of metering pumps 3. Each independent chamber 4 is used to contain different drugs. Each metering pump 3 corresponds to a single independent chamber 4.

[0035] Reference Figure 1 Meanwhile, multiple observation windows 10 are installed on the side wall of the integrated housing 2. The observation windows 10 are made of transparent glass, and each independent chamber 4 corresponds to a single observation window 10. At the same time, the surface of the observation window 10 is engraved with a metering scale, which is used to monitor the liquid volume in the independent chamber 4. This provides an intuitive means of liquid monitoring. The metering scale can provide real-time feedback on the liquid volume, making it easy to quickly determine the remaining amount of the reagent and arrange replenishment in a timely manner, reducing the possibility of production being affected by insufficient reagent.

[0036] Reference Figure 1 and Figure 2 The metering pump 3 is equipped with an inlet pipe 8 at its input end, which connects to the corresponding independent chamber 4. A manual control valve 9 is also installed on the inlet pipe 8. In this embodiment, the manual control valve 9 is used to control the on / off state. The manual control valve 9 provides on / off control for the drug extraction process. It can be flexibly opened or closed according to actual needs, accurately controlling the start and stop of drug supply, effectively avoiding abnormal drug flow due to unexpected situations, and enhancing the controllability of operation.

[0037] Reference Figure 1 and Figure 2In this embodiment, the bottom of each independent chamber 4 is a conical liquid collection structure, and the inlet end of the liquid inlet pipe 8 extends to the lowest point of the conical liquid collection structure; this improves the efficiency of drug utilization. The conical structure can naturally guide the drug in the chamber to converge to the lowest point, ensuring that the liquid inlet pipe 8 can fully extract the residual drug, reduce the accumulation and waste of the drug at the bottom of the chamber, and avoid problems such as deterioration and pollution caused by drug residue.

[0038] Reference Figure 1 A flexible delivery pipe 11 is installed at the output end of the metering pump 3. In this embodiment, the flexible delivery pipe 11 can be a metal flexible hose. The end of the flexible delivery pipe 11 away from the metering pump 3 is connected to a metering manifold 5. The outlet ends of several metering manifolds 5 are jointly provided with a main output manifold 6. In this embodiment, the metering pump 3 is used to extract the agent in the independent chamber 4 and perform precise metering. The metered agent enters the metering manifold 5 through the output end of the metering pump 3. Different agents flow into the main output manifold 6 after passing through their respective metering pumps 3 and metering manifolds 5, and are finally delivered to the textile printing and dyeing equipment.

[0039] Reference Figure 1 Meanwhile, a sealing joint 12 is installed at the connection between the metering manifold 5 and the flexible delivery pipe 11. The sealing joint 12 can effectively fill the tiny gap at the connection between the flexible delivery pipe 11 and the metering manifold 5, forming a reliable sealing barrier to prevent leakage of the medicine during delivery and avoid waste of the medicine.

[0040] Reference Figure 1 The integrated housing 2 is equipped with several supports 14. In this embodiment, the supports 14 are used to fix the main output pipe 6. The multiple supports 14 are arranged along the length of the main output pipe 6 to provide multi-point support for the main output pipe 6, effectively dispersing the weight of the pipe itself and the stress generated during operation, and ensuring the stability of the pipe.

[0041] Reference Figure 1 and Figure 2 The integrated housing 2 is also equipped with a backflushing mechanism 7, which is used to clean the main output manifold 6. The backflushing mechanism 7 includes a backflushing pipeline 71 and a backflushing pump 72. A clean water chamber 13 is formed inside the integrated housing 2. In this embodiment, a chamber for accommodating the backflushing pump 72 can be formed inside the integrated housing 2. At the same time, the backflushing pump 72 can also be located outside the integrated housing 2. The input end of the backflushing pump 72 is connected to the clean water chamber 13 through a pipeline. One end of the backflushing pipeline 71 is connected to the output end of the backflushing pump 72. The backflushing pipeline 71 is connected to the end of the main output manifold 6. In this embodiment, the backflushing pipeline 71 can be equipped with a corresponding valve. This effectively removes residual agents and dirt and other impurities attached to the inner wall of the pipeline, ensuring that the pipeline is clean and unobstructed, avoiding blockages and corrosion caused by the accumulation of impurities, and ensuring stable subsequent liquid supply quality.

[0042] The implementation principle of a micro-liquid supply device for textile printing and dyeing in this embodiment is as follows: During the textile printing and dyeing process, different agents required for textile printing and dyeing are added to the independent chambers 4 separated by the integrated housing 2. Each independent chamber 4 contains a specific agent to ensure that the agents do not contaminate each other. According to the process formula requirements of textile printing and dyeing, the types and amounts of agents to be used are determined, and the metering pump 3 of the corresponding independent chamber 4 is started. The metering pump 3 starts working and extracts the agent in the independent chamber 4 according to the set flow rate and speed. The metering pump 3 accurately measures the extracted agent. The measured agent enters the metering manifold 5 through the output end of the metering pump 3. Different agents flow into the main output manifold 6 after passing through their respective metering pumps 3 and metering manifold 5, and are finally delivered to the textile printing and dyeing equipment for dyeing. At the same time, after the liquid supply work is completed, the backwashing mechanism 7 is started to clean the main output manifold 6 according to the equipment maintenance plan.

[0043] By integrating the housing 2, metering pump 3, independent chamber 4, metering manifold 5, etc., integrated chemical supply is achieved, which greatly improves production efficiency, ensures the accuracy and stability of chemical addition, and guarantees the consistency of dyeing quality. At the same time, combined with the backwashing mechanism 7 to clean the main output pipe 6, it helps to maintain the equipment in good operating condition and reduce the impact of chemical residue.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
