Description

Technical Field

[0001] The present application relates to the technical field of post-desizing treatment of woven fabrics, and in particular to a post-desizing treatment device for woven fabrics. Background Art

[0002] Desizing of woven fabrics is an important textile pretreatment process, which involves soaking and treating the fabric with acidic, alkaline or enzymatic solutions. Its core purpose is to remove the adhesives that are sized on the yarn during the weaving process. These adhesives play a role in stabilizing the warp and weft during the formation of the fabric, but they must be completely removed before further processing, such as scouring, bleaching and dyeing. If desizing is not done, it will not only affect the efficiency and effect of subsequent processing, but may also affect the quality of the final product.

[0003] However, in actual applications, the processing of woven fabrics in cleaning equipment often faces many challenges. One of the most significant problems is that the flexible nature of woven fabrics makes it difficult to effectively fix and support them during the cleaning process. Due to the elasticity and stretchability of the fabric itself, when the cleaning equipment tries to tighten it, the fabric can easily become loose, which not only weakens the processing capacity of the cleaning equipment and reduces the cleaning efficiency, but may also cause damage to the fabric due to unnecessary pulling or squeezing during the cleaning process. This damage may manifest as structural damage to the fabric, displacement of the warp and weft lines, or even serious holes, which seriously affect the quality and service life of the fabric.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0026] The present application discloses a woven fabric desizing post-processing device. Figure 1-Figure 5A woven fabric desizing post-processing device comprises a U-shaped working frame 1, the bottom four corners of the U-shaped working frame 1 are fixed with supporting legs 2, the top is fixed with a U-shaped supporting frame 3, the top of the U-shaped supporting frame 3 is fixed with a water storage tank 4, the inside of the water storage tank 4 is fixed with a partition plate 5, the inside of the U-shaped supporting frame 3 is fixed with two connecting pipes 6, the two connecting pipes 6 are respectively fixed with a plurality of detergent nozzles 7 and water nozzles 8, and the two connecting pipes 6 are connected to the U-shaped supporting frame 3 through pipelines, the bottom of the U-shaped working frame 1 is fixed with a sewage tank 9, and the bottom of the sewage tank 9 is fixed with a drain pipe 10;

[0027] Two mounting grooves 13 are also provided on the U-shaped work frame 1, and two sets of symmetrically distributed conveying rollers 14 are rotatably connected to the two mounting grooves 13. Two second motors 27 for driving the conveying rollers 14 to rotate are installed on the outer wall of the U-shaped work frame 1. The number of the two sets of conveying rollers 14 is three, and they are arranged in a triangle.

[0028] The inside of the U-shaped support frame 3 is located above the U-shaped working frame 1 and is rotatably connected to a soft brush roller 15. The inside of the U-shaped support frame 3 is located above the soft brush roller 15 and is fixed with a first motor 26 for driving the soft brush roller 15 to rotate;

[0029] A first cylinder 18 is fixed on the U-shaped working frame 1 below the soft brush roller 15, the output end of the first cylinder 18 passes through the U-shaped working frame 1 and is fixed with a first U-shaped plate 16, a moving roller 17 is rotatably connected to the first U-shaped plate 16, two support rods 19 are fixed at the bottom of the first U-shaped plate 16, and the two support rods 19 pass through the U-shaped working frame 1; when in use, firstly, by starting the second motor 27, the conveying rollers 14 installed in the mounting grooves 13 on both sides of the U-shaped working frame 1 start to rotate to form a stable cloth transmission path, and at the same time, the first cylinder 18 drives the first U-shaped plate 16 and the moving rollers 17 thereon to move upward, which can ensure that the outer white surface of the cloth is closely attached to the outer wall of the soft brush roller 15, and the triangular layout of the conveying rollers 14 not only enhances the stability of the cloth, but also ensures that the cloth can be evenly stressed during the transmission process to avoid unnecessary wrinkles or distortions;

[0030] As the cloth is transported forward, it first enters the detergent spraying area. The detergent in the water tank 4 is transported to the two connecting pipes 6 through the pipeline, and then evenly sprayed onto the cloth surface by the detergent nozzle 7. This step is to effectively remove the residual slurry and other impurities on the cloth, laying a good foundation for subsequent treatment. The type and concentration of the detergent can be flexibly adjusted according to the cloth material and desizing effect.

[0031] After the detergent spraying is completed, the cloth continues to move forward to the clean water washing area. At this time, the clean water nozzle 8 starts to work and uses the clean water in the water storage tank 4 to thoroughly wash the cloth to remove the detergent residue and excess water. The clean water washing not only improves the cleanliness of the cloth, but also prepares for the subsequent drying process;

[0032] During the cleaning and rinsing process, the soft brush roller 15 is driven by the first motor 26 to slowly rotate, and its soft bristles gently brush the surface of the fabric to further remove stubborn stains and impurities while protecting the fabric from damage. The design of the soft brush roller 15 fully considers the texture and desizing requirements of the fabric, ensuring a double balance between cleaning effect and fabric protection.

[0033] Subsequently, the fabric enters the squeezing area, and driven by the conveying roller 14, the fabric passes through the squeezing channel and is subjected to a moderate squeezing effect, thereby removing excess moisture and shaping the fabric. This squeezing method not only improves the drying efficiency of the fabric, but also helps to maintain the flatness and dimensional stability of the fabric.

[0034] Finally, the fabric that has been thoroughly cleaned, rinsed and squeezed is output from the other end of the device, presenting a clean, flat, dimensionally stable state. The woven fabric desizing post-processing device provided in this application not only improves the cleaning efficiency and effect, but also effectively protects the quality and service life of the fabric, providing strong support for subsequent processing in the textile industry.

[0035] Reference Figure 1 A pair of cover doors 11 are hingedly connected to both sides of the U-shaped support frame 3, and perspective windows 12 are provided on the two pairs of cover doors 11; it is convenient to observe the internal situation of the device during cleaning and maintenance to ensure the safety and efficiency of operation. The perspective window 12 is made of highly transparent and wear-resistant materials, such as tempered glass or special plastics, which can clearly display the working status of the inside of the device and effectively resist corrosion or wear caused by detergents and water.

[0036] Reference Figure 2 , Figure 3 and Figure 4The top of the U-shaped working frame 1 is rotatably connected with a top squeezing roller 20, and a second cylinder 22 is fixed on the U-shaped working frame 1 below the top squeezing roller 20, and a second U-shaped plate 21 is fixed on the output end of the second cylinder 22, and a bottom squeezing roller 23 is rotatably connected to the second U-shaped plate 21.

The second cylinder 22 drives the second U-shaped plate 21 and the bottom squeezing roller 23 thereon to move upward, and together with the top squeezing roller 20, a stronger squeezing effect is formed, further enhancing the dehydration ability of the cloth. This upper and lower double-roller squeezing design not only increases the moisture removal area for the cloth, but also avoids deformation of the cloth during the squeezing process through uniformly distributed squeezing force.

[0037] Reference Figure 2 and Figure 4 The outer wall of the second U-shaped plate 21 is provided with a plurality of through holes 24, and the U-shaped working frame 1 is also provided with a plurality of through holes 24; the through holes 24 provided on the second U-shaped plate 21 and the U-shaped working frame 1 are helpful to collect and discharge the excess water generated during the extrusion process, so as to keep the working environment clean and dry.

[0040] As the cloth is transported forward, it first enters the detergent spraying area. The detergent in the water tank 4 is transported to the two connecting pipes 6 through the pipeline, and then evenly sprayed onto the cloth surface by the detergent nozzle 7. This step is to effectively remove the residual slurry and other impurities on the cloth, laying a good foundation for subsequent treatment. The type and concentration of the detergent can be flexibly adjusted according to the cloth material and desizing effect.

[0041] After the detergent spraying is completed, the cloth continues to move forward to the clean water washing area. At this time, the clean water nozzle 8 starts to work and uses the clean water in the water storage tank 4 to thoroughly wash the cloth to remove the detergent residue and excess water. The clean water washing not only improves the cleanliness of the cloth, but also prepares for the subsequent drying process;

[0042] During the cleaning and rinsing process, the soft brush roller 15 is driven by the first motor 26 to slowly rotate, and its soft bristles gently brush the surface of the fabric to further remove stubborn stains and impurities while protecting the fabric from damage. The design of the soft brush roller 15 fully considers the texture and desizing requirements of the fabric, ensuring a double balance between cleaning effect and fabric protection.

[0043] Subsequently, the fabric enters the squeezing area, and driven by the conveying roller 14, the fabric passes through the squeezing channel and is subjected to a moderate squeezing effect, thereby removing excess moisture and shaping the fabric.

The second cylinder 22 drives the second U-shaped plate 21 and the bottom squeezing roller 23 thereon to move upward, and together with the top squeezing roller 20, a stronger squeezing effect is formed, further enhancing the dehydration capacity of the cloth. This upper and lower double-roller squeezing design not only increases the moisture removal area of ​​the cloth, but also avoids deformation of the cloth during the squeezing process through uniformly distributed squeezing force.

[0045] Finally, the fabric that has been thoroughly cleaned, rinsed and squeezed is output from the other end of the device, presenting a clean, flat, dimensionally stable state.
