Description

TECHNICAL FIELD

[0001] The utility model relates to the field of device equipment for textile printing and dyeing, concretely to a printing and dyeing material storage device capable of automatically adjusting liquid alkali concentration. BACKGROUND

[0002] In the field of printing and dyeing textiles, the composition of printing and dyeing materials is an important factor affecting the quality of textile products and is of great concern in the industry. The devices designed to temporarily store printing and dyeing materials on the market can store printing and dyeing materials adaptively under certain working conditions. For example, a dye storage device disclosed in a Chinese utility model patent document with application number CN202221709494.7 includes a storage assembly, a support assembly, and a transfer assembly. The storage assembly and the support assembly are arranged on both sides of the transfer assembly, and both the storage assembly and the support assembly can hold dye cartridges. The transfer assembly includes a first sliding member, a second sliding member, and a third sliding member. The third sliding member is arranged horizontally on the second sliding member, and the second sliding member is arranged vertically on the first sliding member. The first sliding member, the storage assembly, and the support assembly are parallel to each other, and the sliding directions of the first sliding member, the second sliding member, and the third sliding member are perpendicular to each other. The third sliding member can take and place dye cartridges on the storage assembly and the support assembly to achieve the effect of taking and placing dye cartridges.

[0003] However, the applicant found that the change in the acidity and alkalinity of printing and dyeing materials has a significant impact on the printing and dyeing effect. Specifically, in reactive dye printing and dyeing, when the pH value is too high (alkalinity is too strong), the dye reacts too quickly with the fiber, which can cause color spots, color differences, and damage to the fiber. When the pH value is too low (acidity is too strong), the dye activity decreases, the dyeing depth is insufficient, and the color is too light. Therefore, the pH value in reactive dye printing and dyeing must be strictly controlled to ensure uniform dyeing, bright color, and good fabric performance. For example, in acid dye printing and dyeing, this dye is mainly used for protein fibers such as wool and silk. Under acidic conditions, the dye combines with the amino groups in the fiber to achieve dyeing. If the pH value is too high (alkaline), the dye's ability to bind to the fiber decreases, the dyeing is not firm and easily fades, and the fiber structure may be damaged. If the pH value is too low (acidity is too strong), although the binding ability is enhanced, the fiber will be damaged and the hand feel will be poor. Therefore, the pH value in acid dye printing and dyeing must be accurately controlled according to the type of fiber and the characteristics of the dye to achieve the desired dyeing effect.

[0004] Therefore, during the storage and placement of printing and dyeing materials, the acidity and alkalinity of the dye in the storage device need to be continuously monitored and adjusted in real time to ensure that the dye with appropriate acidity and alkalinity in the storage device can be supplemented into the interior of the printing and dyeing device at any time to achieve better printing and dyeing results.

[0025] The following specific embodiments are merely an explanation of the utility model, and are not a limitation of the utility model, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.

[0026] The present scheme is realized through the following technical means:

[0027] Embodiment: In the embodiment, a printing and dyeing material storage device capable of automatically adjusting the concentration of liquid alkali is given, which realizes real-time monitoring of the concentration of liquid alkali of the printing and dyeing material in the storage device, and real-time regulation and control of the actual acidity and alkalinity of the printing and dyeing material according to the detected vertical, so as to ensure that the acidity and alkalinity of the printing and dyeing material is in an optimal state, thereby obtaining better textile printing and dyeing processing effect.

[0028] Specifically, referring to the drawings Figure 1 The printing and dyeing material storage device capable of automatically adjusting the concentration of liquid alkali given in the embodiment comprises a hollow liquid storage main box body 1, the internal cavity of the box body is used for storing and placing printing and dyeing material, and a monitoring unit 2 for detecting the acidity and alkalinity state of the internal printing and dyeing material is arranged at the bottom position of the internal space of the box body. For example, the implementation structure of the monitoring unit 2 can be selected to mainly consist of the following components: high-precision pH sensor (such as pH4502C or potential pH sensor of KROHNE), temperature compensation module (using DS18B20 or Pt1000 temperature sensor), signal processing and conversion module (based on AD8605 precision operational amplifier), microcontroller (such as Arduino Uno or STM32F103C8T6), display module (LCD1602 or OLED display screen) and communication module (such as ESP8266 Wi-Fi module or HC-05 Bluetooth module). The device immerses the pH sensor (such as pH4502C) into the liquid, uses the glass electrode to sense the hydrogen ion concentration and generates a potential difference signal related to the pH value. At the same time, the temperature sensor (such as DS18B20) measures the liquid temperature to provide data for subsequent compensation. After amplification and filtering processing, the signal is converted into a digital signal by an analog-to-digital converter (ADC), and then the microcontroller (such as Arduino or STM32) combines the temperature data to perform temperature compensation, calculates the accurate pH value, and displays it in real time through the display module (such as LCD1602), and can send a control signal to another module system through the communication module (such as ESP8266).

[0029] And in the outside of the main liquid storage tank 1 is provided with an acid-base adjustment system 3 which can adjust the printing and dyeing dyes according to the pH value of the printing and dyeing dyes in the tank detected by the monitoring unit 2. Specifically, the acid-base adjustment system 3 contains an external compensation liquid storage barrel 301, an external compensation liquid storage barrel 301, and a suction pump unit 302 arranged on the top of the main liquid storage tank 1, which contains a vacuum driven pump as a power device.

[0030] The compensation liquid storage barrel 301 is connected in turn with the suction pump unit 302 and the liquid inlet valve through the communication hose 303, the liquid inlet valve 5 is connected with the inside space of the main liquid storage tank 1, the top of the liquid inlet valve 5 is also connected with the printing and dyeing liquid main pipe 304, and the bottom of the main liquid storage tank 1 is provided with a discharge valve 101 for controlling the discharge of printing and dyeing dyes.

[0031] When the prepared printing and dyeing liquid enters the chamber inside the box through the aforementioned liquid inlet guide valve 5, the pH value will change to some extent as the storage time increases. This is because the internal chemical composition of the printing and dyeing liquid reacts with carbon dioxide, moisture or other impurities in the environment after being stored in the device for a certain period of time, causing the acid-base balance to change. In addition, changes in the humidity of the storage environment will cause the dye to absorb or release water, thereby affecting the concentration of the acid-base composition. This change in pH value will have many adverse effects on the printing and dyeing process: first, changes in pH value will affect the solubility and stability of the dye, leading to uneven dyeing; second, changes in pH value can cause the maximum absorption wavelength of dye molecules to shift, thereby changing the color of the printed product; in addition, too high or too low a pH value can also damage the fiber, reducing its strength and durability; finally, changes in pH value will affect the binding force between the dye and the fiber, reducing the dyeing fastness. Therefore, in the printing and dyeing process, strict control of the pH value of the dye is a key link to ensure the quality of printing and dyeing. Of course, the change in the pH value here is generally unidirectional, so the pH value of the printing and dyeing liquid can be adjusted and controlled by adding a compensating liquid to ensure that the printing and dyeing liquid is in the best acid-base range when it is discharged. For example, the types of compensating liquid here can be divided into acidic and alkaline. Acidic compensating liquids commonly used are glacial acetic acid, citric acid, formic acid, and acetic acid-sodium acetate or citric acid-disodium hydrogen phosphate buffer system, which are suitable for dyeing processes that require an acidic environment, can stabilize the pH value and improve dyeing uniformity. Alkaline compensating liquids include sodium hydroxide, sodium carbonate and sodium bicarbonate mixed solution, as well as ammonia and ammonium sulfate mixed buffer, commonly used for reactive dye cold pad-batch dyeing or wool dyeing, can adjust the alkaline environment and enhance the level dyeing. In addition, there are also special high-molecular-weight organic acid and inorganic acid composite buffers, such as acid buffer LUFIMOL ABC, suitable for dyeing and post-treatment of various fibers. The selection of these compensating liquids needs to be determined according to the type of dye, the type of fiber and the process requirements to ensure the stability of the printing and dyeing process and the quality of the final product.

[0032] The aforementioned compensating liquid is first placed in the aforementioned compensating liquid storage barrel 301, and when the suction pump unit 302 receives the start signal from the monitoring unit 2, it will start working and pump the compensating liquid in the compensating liquid storage barrel 301 into the box and mix with the printing and dyeing liquid, thereby adjusting the acidity of the printing and dyeing liquid.

[0033] As a preferred structure, since the printing and dyeing material is stored in the box, due to the influence of precipitation and other factors, the acid-base state at different positions is not uniform, which may cause the monitoring unit 2 to make a wrong judgment and improper adjustment. Therefore, in the embodiment, a stirring and mixing system 4 for mixing the compensation liquid with the printing and dyeing material to improve the uniformity of the composition of the printing and dyeing material is arranged in the liquid storage main box 1. Figure 1 As shown in the structure, the driving motor 401 is arranged at the bottom, the driving shaft 402 is connected to the output end of the driving motor 401, and the rotating blade 403 is fixedly arranged on the driving shaft 402, and the rotating blade 403 is arranged in a spiral shape on the driving shaft 402. Under this structure, the rotation of the driving shaft 402 and the rotating blade 403 driven by the driving motor 401 can fully stir the internal printing and dyeing material, thereby ensuring the uniformity of the composition during storage, detection and adjustment.

[0034] For the structure of the liquid inlet guide valve 5, the outer valve body 501 is arranged on the outside, and the inner valve body 502 is arranged in the outer valve body 501. The outer valve body 501 is connected to the liquid storage main box 1 and the printing and dyeing material liquid inlet main pipe 304 in a downward and upward manner. The inner valve body 502 comprises a material inlet 5021 arranged on the side and a material outlet 5022 arranged at the bottom, and an active valve core 5023 capable of controlling the communication between the material inlet 5021 and the material outlet 5022 by lifting movement. The active valve core 5023 is controlled and driven to lift by the electromagnetic drive unit arranged at the top of the inner valve body 502.

[0035] Under this structure, the channel space is formed between the inner valve body 502 and the outer valve body 501, so that the printing and dyeing material cannot enter the cavity of the box. The electromagnetic drive unit in the inner valve body 502 is electrically connected to the monitoring unit 2, and the monitoring unit 2 controls the active valve core 5023 to open the inner valve body 502 when the compensation liquid needs to be pumped in, so that the compensation liquid can smoothly enter the box, and the compensation liquid is prevented from entering the box by itself under non-control working conditions.

[0036] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
