Description

Technical Field

[0001] This application relates to the field of fabric processing technology, and in particular to a large-scale fabric pre-dyeing and drying equipment. Background Technology

[0002] As people's living standards continue to improve, the fabric products we encounter daily, such as clothing and home textiles, are not only required to be aesthetically pleasing but also to have higher functional requirements, such as better durability, corrosion resistance, or a unique feel. To meet these demands, fabrics must undergo a series of meticulous pretreatments before final dyeing. A key step is removing impurities through washing and impregnating the fabric with specific chemical auxiliaries to impart predetermined properties. This invention provides an efficient and continuous solution for this crucial pretreatment stage, aiming to improve fabric processing efficiency and quality stability.

[0003] In current production practices, factories typically use dedicated, independent equipment for pretreatment. For example, industrial washing machines are used for intensive cleaning of the fabric. This equipment, through high-pressure water jets or mechanical rubbing, effectively removes sizing agents, oil stains, and impurities adhering to the fabric during the weaving process, thus providing a clean canvas for subsequent processes and ensuring uniformity and vibrancy in printing and dyeing. Similarly, dedicated auxiliary agent padding equipment, through precisely controlled roller pressure, allows auxiliaries to penetrate evenly into the fabric fibers, effectively improving the fabric's physicochemical properties.

[0004] However, this distributed production model relying on multiple independent machines has inherent technical flaws. The core problem lies in the physical isolation between processes, leading to production interruptions. Specifically, after the fabric is processed in the washing machine, it must be unloaded, transferred, and then reinstalled on the auxiliary agent impregnation machine. This series of non-productive auxiliary operations not only consumes a significant amount of manpower and time but also severely disrupts production continuity, resulting in low overall processing efficiency. More importantly, if the wet fabric carrying a large amount of water is directly impregnated with auxiliary agents to simplify the process, the concentration of the auxiliary agents will be rapidly diluted, causing serious instability in product quality. Therefore, existing technologies present an irreconcilable contradiction between ensuring product quality and improving production efficiency, which is precisely the key technical problem that this invention aims to solve.

[0005] In response to the aforementioned technologies, a large-scale fabric pre-dyeing washing and drying treatment device is provided. Summary of the Invention

[0018] 1. This application, by setting up a cleaning tank, conveying rollers, and a water circulation system consisting of a circulating pump and spray pipes, can continuously and efficiently spray and clean the fabric. The wastewater after cleaning enters the screening tank through the drain pipe, where it is purified by a filtration assembly consisting of a filter screen and filter layer, removing impurities from the water. The purified water then flows back to the storage tank through a connecting pipe, thereby realizing the recycling of water resources and saving production costs. The design of the spring and the insert rod ensures the sealing and filtration effect of the filtration assembly, while the valves facilitate the control and maintenance of the water circuit.

[0019] 2. This application provides a dedicated working area for coating fabric with additives by setting up a fixed box. The drive assembly, consisting of a drive motor, belt, rotating roller, etc., can automatically and evenly coat the additives in the box onto the fabric surface. Subsequently, the pressure roller squeezes the fabric, which can effectively remove excess liquid and control the liquid rate. This not only ensures the uniformity of additive impregnation but also avoids waste of additives, realizing automated and standardized coating operations.

[0020] 3. This application achieves efficient drying of fabrics by setting up a drying component; during operation, the air pump draws in air, which is heated by the heating tubes in the heating chamber to form high-temperature hot air. The hot air is then transported to the air collection box and sprayed out at high speed from evenly distributed air jet holes, directly acting on the surface of the fabric to quickly remove moisture. This design, through centralized heating and uniform air supply, ensures that the drying process of the fabric is both fast and uniform, significantly improving drying efficiency.

The system controls the opening and closing of the drain pipe 14 to control wastewater discharge and facilitates water circulation management. The screening box 16 provides installation space for the filter assembly and collects wastewater discharged from the cleaning box 2. The filter assembly filters the wastewater discharged from the cleaning box 2, removing impurities and suspended solids to purify the water and achieve water recycling, thus reducing production costs. The connecting pipe 23 transports the filtered clean water from the screening box 16 back to the storage tank 6 and is a key pipe in the water circulation loop. The control valve 24 controls or cuts off the flow of filtered water back to the storage tank 6, facilitating maintenance of the circulation system.The connecting pipe 23 is fixedly connected to the rear side of the water storage tank 6; the support frame 17 provides stable support for the entire filter assembly; the fixing frame 18 is used to install and fix the filter screen 19 and the filter layer 20, and its sliding connection design facilitates the subsequent replacement and cleaning of the filter screen 19 and the filter layer 20; the filter screen 19 is used for preliminary filtration of wastewater, intercepting larger impurities and fibers in the water flow to prevent them from clogging the subsequent filter layer 20; the filter layer 20 is used for fine filtration of the water filtered by the filter screen 19, removing smaller suspended particles and further improving the cleanliness of the water; the insertion rod 21, together with the spring 22, presses and fixes the filter screen 19 and the filter layer 20. The elastic pressure provided by the spring 22 ensures that the filter screen 19 and the filter layer 20 always remain tightly fitted during operation, preventing wastewater from leaking from the edges and ensuring the filtration effect.

A drive assembly is fixedly connected to the upper side of the support frame 27. The drive assembly is used to coat the fabric. The drive assembly is rotatably connected to the rear side inside the fixed box 25. The drive assembly includes a drive motor 28. The drive motor 28 is fixedly connected to the upper side of the support frame 27. A drive wheel 29 is fixedly connected to the output end of the drive motor 28. A driven wheel 31 is connected to the drive wheel 29 through a belt 30. A rotating shaft 32 is fixedly connected inside both the drive wheel 29 and the driven wheel 31. A rotating roller 33 is fixedly connected to the outside of the rotating shaft 32.

[0032] The fixed box 25 is used to hold the additives and provide installation space for the pressure roller 26 and the drive assembly, allowing the fabric to be impregnated and coated with the additives within this space. The pressure roller 26 is used to squeeze the fabric soaked in the additives, removing excess additive liquid from the fabric, so that the additives can be more evenly distributed in the fabric fibers, and controlling the liquid content of the fabric to prevent additive waste. The support frame 27 is used to support and fix the drive assembly, especially to provide a stable mounting platform for the drive motor 28, ensuring stable output of driving force. The drive assembly is used to drive the rotating roller 33 to rotate, thereby coating or assisting in the conveying of the fabric with additives, and is the core part of realizing the automation of the additive addition process. The drive assembly is rotatably connected to the rear side of the fixed box 25. The drive motor 28 provides power to the entire drive assembly. The drive wheel 29, in conjunction with the belt 30 and the driven wheel 31, transmits the rotational power generated by the drive motor 28 to the rotating roller 33. The belt 30, as a flexible transmission component, connects the drive wheel 29 and the driven wheel 31, transmitting torque smoothly and buffering loads and absorbing vibrations. The rotating shaft 32 serves as the axis of power transmission, transmitting the rotational motion of the wheel to the fixed rotating roller 33, ensuring the reliability of power transmission. The rotating roller 33 rotates under the drive of the rotating shaft 32, and its surface directly contacts the fabric. Through rotation, it lifts the additives at the bottom of the fixed box 25 and coats them onto the fabric surface, achieving the effect of uniformly coating the fabric with additives.

[0033] refer to Figure 1 , Figure 2 and Figure 6 The base plate 1 has fixed brackets 34 on both sides of the upper part. The upper rear side of the fixed bracket 34 has a vacuum pump 35 fixedly connected. The output end of the vacuum pump 35 is fixedly connected to an air supply pipe 36.

The heating box 37 is fixedly connected to the front end of the air supply pipe 36. The inside sides of the heating box 37 have fixed plates 38 fixedly connected. The side of the fixed plates 38 that is close to each other is fixedly connected to a heating pipe 39. The front side of the heating box 37 is fixedly connected to a conveying pipe 40.

[0034] The mounting bracket 34 supports and secures components of the drying system, such as the air pump 35 and the air collection box 41, providing a stable structural foundation for the drying process. The air pump 35 draws in outside air and pressurizes it, providing a continuous and stable air source for the entire hot air drying system and serving as the power source for generating the drying airflow. The air delivery pipe 36 transports the high-pressure airflow generated by the air pump 35 to the subsequent drying components, serving as a channel connecting the power source and the heating unit. The drying components heat the airflow and deliver it to the air collection box 41, forming the core component for generating high-temperature hot air and ultimately achieving rapid drying of the fabric. The air collection box 41 collects and evenly distributes the high-temperature hot air from the drying components, using its internal structure to heat... The air guide jet nozzle 42 ensures that hot air is blown evenly onto the fabric. The jet nozzle 42 is used to spray the high-temperature hot air in the air collection box 41 onto the fabric surface in the form of a high-speed airflow, thereby removing the moisture from the fabric and achieving the effect of efficient and uniform drying of the fabric. The heating box 37 is used to provide a closed installation and working space for the heating tube 39, so that the airflow can be concentrated through the heating area, improving the heating efficiency. The heating tube 39, together with the heating box 37, heats the airflow, achieving the effect of converting room temperature air into high-temperature hot air. The heating tube 39 is electrically heated and generates heat after being powered on. The conveying pipe 40 is used to transport the high-temperature hot air generated in the heating box 37 to the air collection box 41, and is a channel connecting the heating unit and the hot air distribution unit.

[0036] The buckle 11 is used to fix the water pipe 10 in the designated position of the cleaning tank 2, which plays a supporting and limiting role, preventing the water pipe 10 from being displaced due to water flow impact or equipment vibration, and ensuring the stability of the pipeline system. The driving wheel 29 and the driven wheel 31 are rotatably connected to the front sides of the fixed box 25, which supports the rotation of the driving wheel 29 and the driven wheel 31 and determines their relative positions, providing a structural basis for the installation of the belt 30 and stable transmission. The spring 22 can apply a continuous elastic force to the insertion rod 21, and the pressure is transmitted to the filter screen 19 and the filter layer 20 through the insertion rod 21, achieving automatic clamping. The effectiveness of the filter material ensures the airtightness of the filter. A drying component is located on the left side of the washing tank 2. This component is used to pre-dry the fabric that has just been washed, removing most of the moisture it carries. This prevents moisture from being carried into the subsequent coating component, thus preventing the dilution of the auxiliary agent concentration and ensuring the coating quality. The coating component is used to impregnate and coat the fabric with auxiliary agents after the first drying process, thereby improving the fabric's performance. A drying component is located on the left side of the coating component. This component is used to perform the final drying treatment on the wet fabric after the auxiliary agent coating, bringing the fabric to the required dry state for subsequent winding or dyeing processes.
