Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing, and in particular to a nano-processed fabric antifouling and antibacterial production device and process. Background Art

[0002] With the continuous improvement of modern living standards, people have increasingly stringent requirements for the quality of textiles, especially the anti-fouling and antibacterial properties of fabrics, which have received more and more attention. In daily life, various types of textiles are frequently exposed to the external environment, easily stained and become a breeding ground for bacteria, which not only affects their aesthetics, but also may pose a potential threat to human health. For example, common textiles such as clothing and home textiles are difficult to remove stains after long-term use, and they produce odors due to bacterial breeding. This has prompted the textile processing industry to urgently need effective means to improve the anti-fouling and antibacterial capabilities of fabrics to meet consumers' urgent needs for high-quality and healthy textiles.

[0003] However, the current traditional technologies for antifouling and antibacterial treatment of fabrics have many shortcomings. On the one hand, some treatment processes mainly rely on manual operation. In the coating spraying process of the fabric, it is difficult to ensure that the coating can be evenly covered on the surface of the fabric, which is prone to uneven spraying and inconsistent thickness, thus affecting the stability of the antifouling and antibacterial effect. On the other hand, the curing process often adopts a single drying method, such as relying solely on natural drying or conventional heating and drying. It is not only time-consuming and greatly reduces production efficiency, but also for some special nano-scale coatings, it is impossible to give full play to its performance advantages, resulting in unsatisfactory curing effect of the coating. In addition, the traditional process lacks an effective real-time monitoring and dynamic adjustment mechanism, making it difficult to ensure the quality consistency of each batch of products. Once a quality problem occurs, it is difficult to detect and correct it in time.

[0004] In view of the limitations of the existing technology in the antifouling and antibacterial treatment of fabrics, there is an urgent need for a more efficient, highly automated treatment technology and corresponding production equipment that can ensure stable product quality. The coating spraying can be accurately controlled to achieve uniform and appropriate coverage, and the coating can be quickly cured using an efficient curing method, and the product quality can be guaranteed by means of a real-time monitoring and adjustment mechanism, so as to overcome the drawbacks of traditional processes and meet the growing development needs of high performance, high quality, and environmental protection in the field of textile processing. Therefore, the efficient and automated fabric antifouling and antibacterial treatment device and process proposed in the present invention came into being. Summary of the invention

[0005] The present invention focuses on the technical field of antifouling and antibacterial treatment of fabrics, and aims to innovatively propose an efficient and highly automated production device and corresponding process, so as to meet the high performance requirements of the textile processing field for fabrics with excellent antifouling and antibacterial properties, conform to the green development trend of modern industry, and realize the organic combination of efficient production and environmental protection.

[0006] In today's textile processing industry, as people's requirements for fabric quality continue to increase, the antifouling and antibacterial properties of fabrics are increasingly attracting attention. However, traditional treatment methods often have many problems such as low efficiency, excessive manual intervention, unstable treatment effects, and possible adverse effects on the environment. Based on this situation, the present invention is committed to developing a new production device and process to solve these existing pain points and provide a better solution for textile processing.

[0007] Device structure

[0008] (I) Conveying components

[0009] The device of the present invention is equipped with four conveying brackets, and the tops of these conveying brackets are connected by means of the same hinged rotating shaft. Rollers are sleeved on the outer circumference of the rotating shaft, and a conveyor belt is evenly tensioned and installed on the rollers, thereby forming a stable cloth conveying infrastructure. Vertical plates are installed on both sides of the conveyor belt, which have multiple functions. On the one hand, they can fix other components in the device and ensure the stability of the entire device structure; on the other hand, they provide reliable guiding support for the cloth during the conveying process, ensuring that the cloth can move smoothly along the established route and enter the subsequent processing link.

[0010] (II) Spraying components

[0011] The spray box is located above the conveyor belt, and its installation stability is ensured by a fixed connection with the mounting plate. Inside the spray box, multiple guide rods and guide seats are arranged, and both ends rely on the mounting plate to provide support, further enhancing the overall stability. The bottom of the guide seat is connected to the nozzle, which is connected to the delivery pump through a hose to achieve the delivery of paint. The movement of the nozzle is driven by a reciprocating screw, and the position can be flexibly adjusted with the help of the drive assembly, so that a uniform spraying operation can be achieved on the surface of the fabric. In addition, the paint storage tank is arranged on the outside of the conveying assembly, and is equipped with a stirring rack inside. The stirring rack is driven by a combined transmission assembly and can operate synchronously with the spraying operation, effectively preventing the precipitation of paint particles, ensuring that the paint is always in a uniform state, and providing a guarantee for high-quality spraying.

[0012] (III) Curing components

[0013] The curing component is mainly composed of two parts. One is the UV lamp and reflector installed at the outlet of the spray box. The UV lamp can provide ultraviolet light to promote the curing reaction of the coating, while the reflector can reflect the light to the surface of the fabric, significantly improving the efficiency of light utilization, so that all parts of the fabric surface can receive sufficient light to ensure the uniformity of curing; the second is the air outlet arranged inside the spray box, which is interconnected with the air duct connected to the hot air blower. The hot air blower can deliver hot air to the spraying area, and the hot air is evenly blown to the surface of the fabric through the air outlet. On the basis of ultraviolet light curing, it further accelerates the drying and curing process of the coating, greatly shortening the overall curing time.

[0014] (IV) Central Control System

[0015] The central controller is the core control unit of the entire device. It accurately controls each component of the device through electrical connections. For example, it can adjust the conveying speed according to actual production needs, set the movement range of the nozzle, control the start and stop of the UV lamp and the hot air blower, and other operations. At the same time, the system also uses various sensors to collect various data in real time, such as conveying status, spraying uniformity, curing effect and other key information, and feeds these data back to the central controller so that it can make corresponding adjustments in time according to the feedback results, thereby ensuring the stable and efficient operation of the entire production process.

[0016] Process steps

[0017] (1) Fabric preparation and transportation

[0018] First, the fabrics to be processed are placed neatly and orderly on the conveyor belt, and then the central controller sets the appropriate conveying speed according to the characteristics of the fabrics and production requirements, so that the fabrics can enter the subsequent spraying area in a uniform and stable state. The power source of the conveyor belt is the motor, which drives the shaft to rotate synchronously through the sprocket and the transmission chain, thereby realizing continuous, stable and uninterrupted conveying of the fabrics, laying a good foundation for the subsequent processing process.

[0019] (II) Paint preparation and spraying

[0020] Before the spraying operation, the nano-coating in the paint storage tank will be continuously stirred by the stirring rack to avoid the precipitation of nano-particles, so as to keep the paint in a uniform and good state at all times. Then, the paint in the storage tank is transported to the nozzle through the hose under the action of the delivery pump. The nozzle will slide along the guide rod, and its sliding power comes from the reciprocating screw. Through this coordination method, it can ensure that the paint is evenly distributed on the surface of the fabric. In addition, the spraying amount is not fixed, but is automatically and accurately adjusted by the central controller according to the thickness of the fabric and the specific requirements of the coating. At the same time, the spraying speed will also be matched with the delivery speed in real time to ensure that there will be no overlapping areas when spraying on the surface of the fabric, and no parts that need to be processed will be missed, so as to maximize the spraying quality.

[0021] (III) Coating curing

[0022] When the fabric is finished spraying, it will immediately enter the curing stage. At this time, the fabric passes through the irradiation area of ​​the UV lamp, and under the action of ultraviolet light, the coating begins to undergo a curing reaction. The presence of the reflector will reflect the light emitted by the UV lamp to the surface of the fabric, further enhancing the light intensity and the uniformity of curing, so that the coating can be more firmly and evenly cured on the fabric. At the same time, the hot air blower transports hot air into the spray box through the air duct, and the hot air is evenly blown onto the surface of the fabric through the air outlet, which works synergistically with the ultraviolet light curing, greatly accelerating the drying and curing process of the coating, effectively shortening the overall production time and improving production efficiency.

[0023] (IV) Quality monitoring and adjustment

[0024] In the entire production process, sensors play a vital role. They monitor key quality indicators such as spray thickness and curing effect in real time, and feed back these monitored data to the central controller in a timely manner. After receiving the feedback results, the central controller will quickly make corresponding adjustments, such as adjusting the movement speed of the nozzle, the amount of paint sprayed, and the curing time. Through such a dynamic adjustment mechanism, it ensures that the coating quality of each batch of fabrics can maintain a high degree of consistency, thereby ensuring the stability and reliability of product quality.

[0025] (V) Finished product collection

[0026] After curing, the fabric will be conveyed by the conveying component under continuous conveying, and then it can be wound and collected with the help of a winding device, or cut and collected according to specific specifications through cutting equipment, thus completing the production process of the entire fabric antifouling and antibacterial treatment.

[0027] Beneficial Effects

[0028] The fabric antifouling and antibacterial treatment process proposed by the present invention has many significant advantages. First, it realizes the integrated operation of multiple key links such as fabric conveying, spraying, and curing, greatly reducing the degree of manual intervention, not only improving production efficiency, but also reducing the risk of unstable quality caused by differences in manual operation; second, the curing method combining UV lamp and hot air can greatly shorten the drying time of the coating, speed up the production rhythm, and improve production efficiency; third, through the close cooperation of the central controller and the sensor, the entire production process can be dynamically adjusted, and the parameters of each link can be timely optimized according to the real-time monitoring data, which effectively ensures the consistency and reliability of product quality; fourth, the nano coating used in this process has a high utilization efficiency, and compared with traditional coatings, it can reduce pollution to the environment, which is in line with the trend of green development of modern industry and has good environmental protection benefits and sustainable development value.

[0029] In summary, the production device and process of the present invention have demonstrated unique advantages in the field of antifouling and antibacterial treatment of fabrics, and are expected to bring positive impetus to the textile processing industry. BRIEF DESCRIPTION OF THE DRAWINGS
