[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the garment. Fabric production is a complex process of transforming fiber raw materials into finished fabrics, mainly including core steps such as raw material preparation, spinning, weaving, dyeing and finishing, and post-processing.

[0003] In the post-processing stage, woven fabrics often need to be bleached to improve their performance and appearance. However, existing bleaching devices often simply immerse the fabric in the bleaching solution, and it is easy for workers to immerse the fabric in the bleaching solution in a wrinkled state without proper production standards, resulting in poor performance and appearance of the produced fabric. Therefore, we have specially designed a bleaching device for woven fabrics. Utility Model Content

[0016] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] Example 1: This embodiment provides a bleaching device for woven fabrics, including: Rinse tank 1, with inclined structures 11 at both ends of rinsing tank 1, and rinsing tank 1 is filled with rinsing solution. The extension roller assembly includes a fixed roller assembly 21 and a movable roller assembly 22. The fixed roller assembly 21 is disposed in the rinsing tank 1, and the movable roller assembly 22 is connected to a drive device 23. The drive device 23 is disposed on the rinsing tank 1 and drives the movable roller assembly 22 to be submerged in or out of the rinsing tank 1. The feeding mechanism 3 is installed on the rinsing tank 1 and is used to guide the fabric 10 through the rinsing tank 1. The fixed roller group 21 and the movable roller group 22 are arranged alternately.

[0018] As can be seen from this embodiment, a rinsing device for woven fabric 10 includes a rinsing tank 1, a stretching roller group and a feeding mechanism 3; The fixed roller group 21 and the movable roller group 22 are arranged alternately, so that the fabric 10 forms a zigzag transmission path in the rinsing tank 1, which prolongs the contact time and contact area between the fabric 10 and the rinsing solution, avoids the problem of insufficient or excessive bleaching in some areas, and helps to improve the consistency of rinsing quality.

[0019] Furthermore, the staggered rollers exert a bidirectional stretching effect on the woven fabric 10 during the transmission process. Combined with the wetting effect of the rinsing solution, this effectively eliminates the wrinkles of the fabric 10 before bleaching, allowing the fibers of the fabric 10 to fully unfold, ensuring the smoothness of the fabric 10 after bleaching, and reducing the difficulty of subsequent finishing processes.

[0020] The movable roller group 22 can be switched to be submerged in or removed from the rinsing tank 1 via the drive device 23. On the one hand, it can be lifted up during feeding to facilitate the threading of the fabric 10. On the other hand, when the equipment is under maintenance or stopped, the movable roller group 22 can be removed from the rinsing tank 1 to facilitate operation and maintenance and improve the ease of use of the equipment.

[0021] The feeding mechanism 3 works in conjunction with the staggered roller group to guide the fabric 10 through the rinsing tank 1 precisely, avoiding the fabric 10 from shifting, tangling or getting stuck during the transmission process, ensuring the continuous and stable operation of the bleaching process and improving production efficiency.

[0022] The sloping structure 11 at both ends of the rinsing tank 1 can reduce the splashing of rinsing solution when the fabric 10 enters and exits, while creating a stable flow environment for the solution in the tank, avoiding uneven local solution concentration, improving the utilization rate of rinsing solution, and reducing the consumption of water resources and chemical agents.

[0023] By setting up a rinsing tank 1, staggered fixed roller groups 21 and movable roller groups 22, and feeding mechanism 3, the uniformity and stretchability of the bleached fabric 10 are ensured, and the product quality is improved. Furthermore, by combining feeding mechanism 3 and ramp structure 11, production stability and resource utilization efficiency are ensured.

[0024] The overall structure is scientifically and rationally designed, easy to operate and maintain, and can effectively meet the high-efficiency and high-quality production requirements of the 10 bleaching process for woven fabrics. It has good practicality and application value.

[0025] Example 2: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0026] The feeding mechanism 3 includes: Slide rail 31 is provided on both sides of rinsing tank 1; Two electric sliding tables 32 are respectively installed on the slide rails 31 located on both sides of the rinsing tank 1; The clamp 33 is connected between two electric slides 32 and clamps the fabric 10.

[0027] As can be seen from this embodiment, the guiding mechanism includes a slide rail 31, an electric slide table 32, and a clamp 33; The feeding mechanism 3 works in conjunction with the electric slide table 32 via the slide rails 31 on both sides of the rinsing tank 1 to drive the clamp 33 to move smoothly along a fixed track, which can accurately guide the fabric 10 through the rinsing tank 1 along a preset path, thus playing the role of threading.

[0028] The clamp 33 reliably holds the fabric 10, and in conjunction with the uniform speed drive of the electric slide table 32, it pulls the fabric 10 out. After the electric slide table 32 drives the clamp 33 to pull the fabric 10 from one end of the slide rail 31 to the other end, the drive device 23 drives the movable roller group 22 to move downward, and stretches and presses the fabric 10 during the displacement process, so that the fabric 10 forms a tortuous movement path in the rinsing tank 1.

[0029] The electric slide table 32 can be automatically driven, eliminating the need for manual traction of the fabric 10 and reducing the intensity of manual labor; and the clamping and releasing actions of the clamp 33 can be flexibly controlled in accordance with the process rhythm, making it easier to thread the fabric 10 and improving the automation level and production convenience of the equipment.

[0030] Example 3: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] Fixture 33 includes: Fixing plate 331, which is made of a metal sheet that can be magnetically attracted; Magnetic strip 332 is disposed on fixing plate 331. Magnetic strip 332 attracts fixing plate 331 to clamp fabric 10. The fixing plate 331 has a notch 3311, and the magnetic strip 332 is connected to the notch 3311.

[0032] As can be seen from this embodiment, the clamp 33 includes a fixing plate 331 and a magnetic strip 332; The fixing plate 331 is made of a metal sheet that can be magnetically attracted. Together with the magnetic strip 332 set at the notch 3311, it quickly clamps the fabric 10 through magnetic attraction. There is no need for a complex mechanical locking structure. The clamping response is fast and the clamping is strong. It can effectively prevent the fabric 10 from loosening or slipping during transmission, ensuring transmission stability. It can also automatically adjust the adsorption gap according to the thickness of the fabric 10, without the need to manually adjust the clamping force. It can stably clamp thin fabrics 10 and prevent thick fabrics 10 from being squeezed, deformed or damaged due to excessive clamping, thus improving clamping adaptability.

[0033] Furthermore, the design of the notch 3311 provides a precise installation position for the magnetic strip 332, ensuring that the magnetic strip 332 and the adsorption surface of the fixing plate 331 are precisely aligned, thereby enhancing the magnetic force transmission efficiency. At the same time, the overall structure has no complicated transmission parts, and the insertion and removal of the fabric 10 can be completed simply by overcoming the magnetic force, making the operation convenient and reducing the intensity of manual labor.

[0034] Example 4: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0035] The fixed roller group 21 includes: The first rotating roller 211 has a first limiting edge 2111 on both sides of the roller body, and the shafts on both sides of the first rotating roller 211 are connected to the wall of the rinsing tank 1. Turntable 212 is disposed at both ends of the first rotating roller 211 and fixed to the walls on both sides of the rinsing tank 1.

[0036] As can be seen from this embodiment, the fixed roller group 21 includes a first rotating roller 211 and a turntable 212, and a plurality of first rotating rollers 211 are equidistantly arranged in the rinsing tank 1; The first limiting edge 2111 on both sides of the first rotating roller 211 forms an axial constraint, which can laterally limit the woven fabric 10 during the transmission process, prevent the fabric 10 from shifting left or right or moving around on the roller, and ensure that the fabric 10 always passes through the rinsing tank 1 along the preset path and comes into uniform contact with the rinsing solution, thus ensuring the consistency of the bleaching effect.

[0037] Furthermore, the design of the first limiting edge 2111 keeps the contact area of ​​the fabric 10 on the first roller 211 stable, avoids local force concentration caused by the offset of the fabric 10, reduces the risk of stretching deformation or wrinkling of the fabric 10, and at the same time ensures uniform friction between the fabric 10 and the roller, ensures stable tension during the transmission process, and improves the flatness of the fabric 10 after bleaching.

[0038] The turntable 212 is fixed to both sides of the rinsing tank 1 and cooperates with both ends of the first roller 211. On the one hand, it provides double support and fixation for the shaft of the first roller 211, which enhances the structural strength of the first roller 211 after installation and prevents the roller from shaking or deforming under high-speed rotation or the tension of the fabric 10. On the other hand, the fixed connection between the turntable 212 and the tank wall can distribute the force, reduce the wear at the connection between the shaft and the tank wall, and extend the service life of the roller assembly.

[0039] Example 5: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The movable roller assembly 22 includes: The fixing frame 221 includes a main frame 2211 and a secondary frame 2212, with multiple secondary frame bodies 2212 symmetrically arranged in a rib-like pattern on the fixing frame 221. The second rotating roller 222 has a second limiting edge 2221 on both ends of the roller body, and the shafts on both sides of the second rotating roller 222 are connected to the sub-frame 2212. The sub-frame 2212 is located between adjacent first rollers 211.

[0041] As can be seen from this embodiment, the movable roller group 22 includes a fixed frame 221 and a second rotating roller 222; Multiple sub-frames 2212 are symmetrically arranged in a rib-like pattern on both sides of the main frame 2211, and are connected to multiple second rollers 222. The ends of the bent parts of the sub-frames 2212 are provided with shaft holes that connect to the shafts on both sides of the second rotating shaft.

[0042] The main frame 2211 is further combined with the ribbed sub-frame 2212 to form a truss-like stable support system, which disperses the tension of the fabric 10 and the resistance of the solution borne by the second roller 222, and prevents the movable roller group 22 from shaking or deforming when it is raised, lowered or rotated; the connection between the shaft of the second roller 222 and the sub-frame 2212 and the second limiting edge 2221 on both sides of the second roller 222 effectively ensure the smooth rotation of the roller and prevent the fabric 10 from shifting.

[0043] The fixed frame 221 enables multiple second rollers 222 to rise and fall synchronously with the drive device 23. Combined with the precise alignment of the sub-frame 2212 and the first roller 211, the zigzag amplitude of the fabric 10 transmission path can be flexibly changed by adjusting the height of the movable roller group 22 to adapt to the bleaching requirements of woven fabrics 10 of different thicknesses and materials. When inspecting or threading materials, the movable roller group 22 is completely removed from the rinsing tank 1, providing more operating space.

[0044] Furthermore, the staggered second rollers 222 cooperate with the first rollers 211 to form a bidirectional and uniform stretching effect on the fabric 10 during transmission. Combined with the rinsing solution, this effectively stretches the fibers of the fabric 10 and eliminates wrinkles. The uniform distribution of the rib-shaped subframes 2212 ensures that each second roller 222 is subjected to balanced force, guaranteeing stable tension during fabric transmission and reducing the risk of stretching deformation.

[0045] Example 6: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] Connecting columns 4 are provided on multiple sub-frames 2212 located in the middle section of the main frame 2211. Connecting frames 5 are connected to the connecting columns 4 and are connected to the drive device 23.

[0047] As can be seen from this embodiment, the sub-frame 2212 in the middle section of the main frame 2211 is provided with a connecting column 4, and a connecting frame 5 is connected to the connecting column 4, so that the driving force of the driving device 23 acts on the center of gravity area of ​​the movable roller group 22, avoiding tilting and jamming during lifting due to force deviation.

[0048] Furthermore, the force in the middle section can be evenly transmitted to the ribbed subframe 2212 and each second rotating roller 222, ensuring that the movable roller group 22 is simultaneously submerged in or leaves the rinsing tank 1, and ensuring the accuracy of the interleaving with the fixed roller group 21.

[0049] The centralized connection structure (connecting column 4, connecting frame 5) reduces the number of connection points between the drive unit 23 and the movable roller group 22. During assembly, only the middle connecting frame 5 needs to be positioned to complete the drive connection, improving assembly efficiency. In subsequent maintenance, the drive component or movable roller group 22 can be quickly disassembled through the connecting frame 5, reducing maintenance complexity.

[0050] Example 7: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] The connecting frame 5 includes a crossbeam frame 51 and an assembly frame 52. The crossbeam frame 51 has holes at both ends that cooperate with the pins of the connecting column 4. The assembly frame is integrally bent and formed on the upper side of the crossbeam frame 51. The bent part of the assembly frame is provided with a connecting end 521 that connects to the driving device 23.

[0052] As can be seen from this embodiment, the connecting frame 5 includes a crossbeam frame 51 and an assembly frame 52; The two ends of the crossbeam frame 51 are connected to the connecting column 4 by pins through holes. During assembly, only the pins need to be aligned to complete the initial fixation, without the need for complicated alignment procedures, thus improving assembly efficiency. The pin-fitting structure has precise positioning, which can ensure the coaxiality of the connecting frame 5 and the sub-frame 2212 in the middle section of the main frame 2211, avoid the force displacement caused by loose connection, and enhance the connection stability.

[0053] The assembly frame 52 is integrally bent and formed on the upper side of the crossbeam frame 51. The integrally formed structure has no splicing gaps, which greatly improves the overall rigidity and deformation resistance of the connecting frame 5. The bending design makes the assembly frame 52 form a mechanical support structure, which can evenly transmit the driving force of the drive device 23 to each connecting column 4 through the crossbeam frame 51, avoid local stress concentration, and ensure that the load is distributed and transmitted to the entire movable roller group 22.

[0054] The detachable structure with pin engagement makes it easy to disassemble the connecting frame 5 from the main frame 2211. During subsequent maintenance, the connecting frame 5 and the movable roller group 22 can be quickly separated, which facilitates the inspection and replacement of the drive device 23, connecting column 4 or roller group components. The one-piece molded connecting frame 5 has no easily damaged splicing parts, reducing failure points and lowering maintenance frequency and cost.

[0055] Example 8: This embodiment provides a bleaching device for woven fabrics, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] The drive unit 23 is an electric telescopic machine, and a mounting bracket 6 is provided on the outer wall of the rinsing tank 1.

[0057] As can be seen from this embodiment, the drive device 23 is an electric telescopic machine; The electric telescopic machine has precise stroke control capabilities and can accurately adjust the telescopic amount through the electronic control system to achieve precise control of the lifting height of the movable roller group 22, adapting to the folding transmission requirements of different fabrics 10; its operation stability is better than that of pneumatic and hydraulic drives, which can avoid impact and vibration when the movable roller group 22 is lifted and lowered, and ensure the interlacing accuracy with the fixed roller group 21.

[0058] The embodiments of this application have been described above with reference to the accompanying drawings.
