Description

Technical Field

[0001] This invention relates to the field of textile dyeing and finishing technology, specifically to an integrated equipment for rinsing and dyeing cotton knitted fabrics. Background Technology

[0002] Cotton knitted fabrics are widely used in clothing such as underwear, T-shirts, and loungewear due to their excellent moisture absorption, breathability, and wearing comfort. The processing of cotton knitted fabrics typically involves several wet treatment steps, including scouring and bleaching (desizing, refining, and bleaching), washing, and dyeing, to remove pectin, waxes, pigments, and impurities from the natural fibers and to impart the desired color to the fabric.

[0003] In traditional processing methods, scouring, bleaching, washing, and dyeing processes are typically completed in separate, independent machines. Specifically, the fabric first undergoes alkaline-oxygen scouring and bleaching treatment in scouring and bleaching equipment (such as a scouring pan or continuous scouring and bleaching machine). Then, the roll or rope-shaped fabric is transferred to washing equipment for multiple hot water washes to remove residual alkali and impurities. Finally, it is transferred to a dyeing machine (such as an overflow dyeing machine or an airflow dyeing machine) for dyeing. Each process involves intermediate steps such as unloading, stacking, handling, and reloading, leading to low production efficiency, high labor costs, and the fabric being prone to quality defects such as wrinkles, abrasions, and weft skew during multiple transfers.

[0004] To address the aforementioned issues, some existing technologies attempt to integrate scouring and dyeing processes. However, these technologies still have several shortcomings in practical applications. First, scouring and bleaching typically require high-temperature alkaline conditions, while dyeing requires maintaining a specific temperature depending on the dye type. The two processes have significantly different requirements for process temperature, liquid chemical composition, and processing time. Existing integrated equipment struggles to independently and precisely control the temperature and chemical environment of each area, leading to substandard scouring and bleaching results or colorfastness. Second, cotton knitted fabrics undergo significant changes in size and tension during scouring and bleaching due to fiber swelling and chemical reactions. Dyeing, on the other hand, requires the fabric to maintain uniform and stable tension to facilitate even dye penetration. Existing equipment lacks independent adjustment and dynamic compensation mechanisms for the fabric transfer speed in each processing section, easily causing fabric accumulation or excessive stretching between processes, affecting processing uniformity. Third, if residual alkaline solution adhering to the fabric surface after scouring and bleaching is not fully removed before entering the dyeing area, it will alter the pH value of the dye solution, leading to dye hydrolysis or a decrease in dye uptake. Existing equipment lacks efficient residual solution isolation and removal methods at process junctions, affecting dyeing quality.

[0005] Furthermore, cotton knitted fabrics have better extensibility and elasticity than woven fabrics, making them more sensitive to fabric tension during continuous wet finishing processes. Achieving independent yet coordinated transmission control of the scouring, bleaching, washing, and dyeing zones within integrated equipment, while ensuring a smooth transition of the fabric between each processing zone, is a pressing technical challenge in the continuous dyeing and finishing of cotton knitted fabrics. Summary of the Invention

[0006] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide an integrated washing and dyeing equipment for cotton knitted fabrics, so as to solve the problems of low efficiency and quality damage caused by frequent transfer between processes in the existing segmented processing, as well as uneven fabric tension and poor processing effect caused by the mismatch of speeds in each processing segment.

[0007] The technical solution adopted by the present invention to achieve the above objectives is: an integrated washing and dyeing equipment for cotton knitted fabrics, comprising:

[0008] The mounting box is equipped with a scouring and bleaching area, a washing area, and a dyeing area arranged from top to bottom. The fabric being processed passes through the scouring and bleaching area, the washing area, and the dyeing area in sequence for corresponding processing.

[0012] A take-up and release assembly is assembled to the fabric storage area and is used to take up and release the fabric to adjust the fabric to adapt to the speed difference between the scouring and bleaching area, the washing area, and the dyeing area.

[0013] Based on the above technical solutions, in order to ensure that the bleaching and rinsing components can be stably assembled and operated in the bleaching and rinsing area, and to achieve effective transfer and bleaching of the fabric, the following technical solutions are provided.

[0014] The bleaching and rinsing assembly includes an aeration roller, a lifting bracket, and a vibrating roller. The aeration roller is rotatably mounted to the bleaching and rinsing area and arranged horizontally. The lifting bracket is slidably mounted in the bleaching and rinsing area and arranged above the aeration roller. The vibrating roller is rotatably mounted on the lifting bracket and arranged vertically. The aeration roller and the vibrating roller are arranged alternately in the horizontal direction. The fabric entering the bleaching and rinsing area is sequentially transported around the aeration roller and the vibrating roller.

[0015] Based on the above technical solutions, in order to ensure that the aeration roller can drive the fabric to be transported stably and to achieve stable aeration in the scouring and bleaching area, the following technical solutions are provided.

[0016] An axial passage is provided at the axis of the aeration roller. A steam supply connector that is rotatably connected to the end of the aeration roller is fixedly installed on the mounting box. The axial passage is connected to the steam supply connector. A transmission sprocket A is also coaxially fixed to the end of the aeration roller. The transmission sprockets A on two adjacent sets of aeration rollers are connected by a chain. One set of aeration rollers is also connected to a drive motor A. The outer wall of the aeration roller is provided with air distribution grooves distributed in a reversing array. The aeration roller is also provided with radial passages distributed in a ring array. The radial passages are connected to the axial passage and the air distribution grooves.

[0017] Based on the above technical solutions, in order to ensure that the lifting support can drive the vibrating roller to move back and forth vertically in the scouring and bleaching area, thereby assisting in the efficient scouring and bleaching treatment of the fabric, the following technical solutions are provided.

[0018] The practice area is equipped with a guide seat, and a guide shaft is fixedly connected to the lifting bracket to maintain a sliding combination with the guide seat. The guide shaft is equipped with a return spring at both ends that abut against the lifting bracket and the guide seat respectively.

[0019] The practice float assembly also includes multiple sets of camshafts rotatably mounted to the practice float area and arranged in a horizontal direction. The lifting bracket abuts against the camshafts. Each set of camshafts has a transmission sprocket B fixedly connected to its end. Adjacent sets of transmission sprockets are connected to each other via a chain. One set of camshafts is also connected to a drive motor B.

[0020] Based on the above technical solutions, in order to ensure that the cleaning components can be stably assembled in the cleaning area and to realize the washing and dehydration treatment of the fabric after scouring and bleaching, the following technical solutions are provided.

[0021] The cleaning area is provided with multiple sets of sequentially arranged water storage tanks. The cleaning assembly includes a cleaning roller, a transmission roller, and a roller A arranged in each set of water storage tanks. The roller A is arranged on the upper downstream side of the water storage tank and is used to dehydrate the fabric. The transmission roller is used to drive the fabric to be continuously transported in each set of water storage tanks. The cleaning roller is arranged in the water storage tank and is used to clean the fabric.

[0022] Based on the above technical solutions, in order to ensure the stable operation of the cleaning roller and the transmission roller so as to achieve effective transmission and cleaning of the fabric, the following technical solutions are provided.

[0023] Each set of cleaning rollers has a drive sprocket C fixedly connected to its end. The drive sprockets C on two adjacent sets of cleaning rollers are connected by a chain. One set of cleaning rollers is also connected to a drive motor C. Each set of transmission rollers has a drive sprocket D fixedly connected to its end. The drive sprockets D on two adjacent sets of transmission rollers are connected by a chain. One set of transmission rollers is also connected to a drive motor D.

[0024] Based on the above technical solutions, in order to ensure that the dyeing components can be stably assembled in the dyeing area and to achieve effective dyeing of the fabric transferred there, the following technical solutions are provided.

[0025] The dyeing assembly includes an upper support roller and a lower support roller rotatably mounted in the dyeing area. Both the upper and lower support rollers include multiple sets evenly arranged in the horizontal direction. The upper and lower support rollers are arranged alternately in the horizontal direction. Each set of upper support rollers is fixedly connected to a drive sprocket E at its end. The drive sprockets E on two connected sets of upper support rollers are powered by a chain. One set of upper support rollers is also powered by a drive motor E.

[0026] Based on the above technical solutions, in order to ensure the effective removal of excess dye from the dyed fabric, the following technical solutions are provided.

[0027] A collection trough is also provided on the downstream side of the dyeing zone. The dyeing assembly also includes multiple sets of rollers B assembled in the collection trough. The rollers B are used to remove excess dye from the fabric and collect it into the collection trough.

[0028] Based on the above technical solutions, in order to ensure that the take-up and release components can be stably assembled in the corresponding fabric storage area, and to realize the take-up and release adjustment of the fabric stored therein to cope with the speed difference in each processing component, the following technical solutions are provided.

[0029] The take-up and release assembly includes a sliding bracket, a movable roller, a fixed roller, and a hydraulic telescopic cylinder. Multiple sets of sliding brackets arranged side by side are slidably installed in each of the fabric storage areas. The hydraulic telescopic cylinder is fixedly installed on the mounting box and maintains a power connection with the sliding bracket. A movable roller is rotatably installed on each set of sliding brackets. The fixed roller is rotatably installed in the fabric storage area. The fabric is arranged sequentially around each set of movable rollers and fixed rollers.

[0030] Based on the above technical solutions, in order to ensure the effective removal of excess residual liquid from the fabric after scouring and bleaching, and to ensure efficient cleaning by downstream cleaning components, the following technical solutions are provided.

[0031] A roller C is rotatably installed in the fabric storage area located on the side below the bleaching and washing area. The roller C is arranged parallel to the fixed roller, and the fabric passes through the gap between the roller C and the fixed roller.

[0032] The beneficial effects of this invention are:

[0033] 1. By setting up scouring, bleaching, washing, and dyeing zones arranged sequentially from top to bottom within the mounting chassis, the fabric passes through each zone sequentially to complete the scouring, bleaching, washing, and dyeing processes. All functional components are integrated into the same equipment, eliminating the need for fabric unloading, handling, and reloading between processes. Compared to traditional segmented processing methods, this effectively shortens the production cycle, reduces manual intervention, and avoids quality defects such as wrinkles, abrasions, and weft skew caused by multiple fabric transfers. It is particularly suitable for efficient, high-quality dyeing and finishing of cotton knitted fabrics.

[0034] 2. In the scouring and bleaching zone, high-temperature steam is continuously supplied to the high-temperature alkaline / hydrogen peroxide treatment solution via aeration rollers, achieving precise heating and temperature maintenance to meet the high-temperature alkaline environment required for scouring and bleaching. The dyeing zone, on the other hand, receives dye liquor at a specific temperature independently, and the arrangement of upper and lower support rollers ensures thorough dyeing of the fabric. The treatment solutions in each zone are independently circulated and replenished, without interference, effectively avoiding problems such as incomplete scouring and bleaching or decreased color fastness caused by cross-process conditions, ensuring optimal treatment results for each step.

[0035] 3. Due to the different time requirements of each process—scouring, bleaching, washing, and dyeing—the fabric transfer speeds of each functional component vary. This invention includes a fabric storage area downstream of the scouring and washing zones. A hydraulic telescopic cylinder in the take-up and release component drives the movable roller to move relative to the fixed roller, allowing for real-time take-up and release of the fabric stored in the storage area based on the speed difference between the upstream and downstream components. This ensures the fabric maintains a stable tension or appropriate relaxation state throughout its flow across each processing zone, preventing fabric accumulation, wrinkling, or excessive stretching due to speed mismatch, and guaranteeing a uniform and stable processing effect in each area.

[0036] 4. The scouring and bleaching assembly employs a horizontally alternating arrangement of aeration rollers and vibrating rollers. While driving stable fabric transport, the aeration rollers continuously release high-temperature steam into the treatment solution, maintaining the alkali solution and hydrogen peroxide at effective operating temperatures. The lifting bracket drives the vibrating rollers in a vertical reciprocating motion, causing the fabric to undergo continuous cyclical changes in tension and relaxation. This synergistic effect of steam impact and mechanical vibration effectively loosens and removes pectin, waxes, and natural pigments adhering to and within the cotton fibers. The scouring and bleaching effect is superior to simple chemical impregnation or simple mechanical rubbing, and the processing time is significantly shortened.

[0037] 5. The washing area is equipped with multiple sets of sequentially arranged water tanks. The fabric is washed with hot water in multiple stages, and mechanical cleaning is carried out in conjunction with the brushes distributed in a reversible array on the washing rollers. This can effectively remove residual alkali and impurities adhering to the fabric. The roller C downstream of the scouring and bleaching area and the roller A above each water tank perform multi-stage squeezing and dehydration during the fabric's movement. This effectively reduces the liquid carryover rate of the fabric entering the dyeing area, prevents residual alkali from being carried into the dye liquor with the fabric, and avoids pH fluctuations in the dye liquor and dye hydrolysis, thus ensuring dyeing reproducibility and color fastness.

[0038] 6. A collection trough located downstream of the dyeing zone is equipped with multiple sets of rollers B. When the dyed fabric passes through rollers B, the excess dye liquor adsorbed between the fibers is removed under the squeezing action and collected in the collection trough. This avoids waste and subsequent washing burden caused by excess dye liquor being carried out with the fabric. Furthermore, the recovered dye liquor can be mixed and reused in the dyeing zone, reducing dye consumption and production costs, and meeting the requirements of green and clean production.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0051] Example 1

[0052] Please see Figures 1-3 An integrated washing and dyeing equipment for cotton knitted fabrics, comprising:

[0053] The mounting box 1 is equipped with a scouring and bleaching area 11, a washing area 12, and a dyeing area 13 arranged from top to bottom. The fabric 6 being processed passes through the scouring and bleaching area 11, the washing area 12, and the dyeing area 13 in sequence for corresponding processing. A fabric storage area 14 is also provided at the downstream end of the scouring and bleaching area 11 and the washing area 12.

[0054] The bleaching and rinsing component 2 is assembled into the bleaching and rinsing area 11 and used to bleach and rinsing the fabric 6.

[0055] Cleaning component 3 is assembled in the cleaning zone 12 and used to clean and dehydrate the fabric 6 after scouring and bleaching.

[0056] Dyeing component 4 is assembled into dyeing zone 13 and used to dye the cleaned fabric 6.

[0057] The take-up and release assembly 5 is assembled to the fabric storage area 14 and is used to take up and release the fabric 6 to adapt the fabric 6 to the speed difference between the scouring and bleaching area 11, the washing area 12, and the dyeing area 13.

[0058] The integrated rinsing and dyeing equipment provided in this solution can effectively improve the dyeing efficiency of knitted fabric 6. The installation chassis 1 ensures the stable assembly and operation of all functional components and provides containers for water, chemicals, and dyes required during the process. With the cooperation of corresponding chemicals and functional components, the fabric 6 is transferred, bleached, washed, and dyed.

[0059] When fabric 6 enters the bleaching zone 11 for bleaching treatment with the help of the bleaching component 2, high-temperature alkali and hydrogen peroxide that are continuously replenished are added to the bleaching zone 11. Fabric 6 is transported under the drive of the bleaching component 2 and the pectin, wax and pigment contained on it are cleaned.

[0060] When the fabric 6 enters the cleaning zone 12 and is cleaned by the cleaning component 3, hot water is added to the cleaning zone 12. The fabric 6 is then transported in the cleaning zone 12 by the cleaning component 3. The hot water is used to clean the residual alkali and impurities attached to the fabric and to dehydrate the attached residual water.

[0061] When fabric 6 enters dyeing zone 13 and is dyed using dyeing component 4, dye solution of a specific temperature is added to dyeing zone 13, and then dyeing component 4 drives fabric 6 to be transferred and immersed in dye solution so that dye solution is evenly attached to the fibers of fabric 6 to achieve efficient dyeing of fabric 6.

[0062] During actual operation, the residence time of fabric 6 in scouring and bleaching zone 11, washing zone 12, and dyeing zone 13 is different due to process requirements. Therefore, the transmission speed of fabric 6 by scouring and bleaching component 2, washing component 3, and dyeing component 4 is not the same. Therefore, the retraction and release component 5 is used to adjust the retraction and release to keep fabric 6 in a taut state when it flows through each processing zone, thereby ensuring that fabric 6 can stably achieve the corresponding processing in each zone.

[0063] Example 2

[0064] Please see Figures 2-6 To ensure that the bleaching assembly 2 can be stably assembled and operated in the bleaching zone 11, and to achieve effective transfer and bleaching of the fabric 6, the following technical solution is provided.

[0065] The rinsing and bleaching assembly 2 includes an aeration roller 21, a lifting bracket 22, and a vibrating roller 23. The aeration roller 21 is rotatably installed in the rinsing and bleaching area 11 and arranged in the horizontal direction. The lifting bracket 22 is slidably installed in the rinsing and bleaching area 11 and arranged above the aeration roller 21. The vibrating roller 23 is rotatably installed on the lifting bracket 22 and arranged in the vertical direction. The aeration roller 21 and the vibrating roller 23 are arranged alternately in the horizontal direction. The fabric 6 entering the rinsing and bleaching area 11 is transported by passing around the aeration roller 21 and the vibrating roller 23 in sequence.

[0066] The aeration roller 21 is used to continuously transmit high-temperature steam to the scouring and bleaching zone 11 to heat the alkaline solution and hydrogen peroxide added to the scouring and bleaching zone 11 to a specific temperature. Under the active operation of the aeration roller 21, it can also drive the fabric 6 to be stably transmitted downstream. The lifting bracket 22 is used to drive the vibrating roller 23 to move up and down in the vertical direction, thereby continuously adjusting the tension and relaxation of the transmitted fabric 6. Under the combined action of the high-temperature steam output by the aeration roller 21, the fabric 6 can be limited to change tension, thereby effectively cleaning the pectin, wax and original pigments attached to the fabric 6.

[0067] To ensure that the aeration roller 21 can drive the fabric 6 to be transported stably and to achieve stable aeration of the scouring and bleaching zone 11, the following technical solution is provided.

[0068] An axial passage 211 is provided at the axis of the aeration roller 21. A steam supply connector 212, which is rotatably connected to the end of the aeration roller 21, is fixedly installed on the mounting housing 1. The axial passage 211 is connected to the steam supply connector 212. A transmission sprocket A213 is also coaxially fixed to the end of the aeration roller 21. The transmission sprockets A213 on two adjacent sets of aeration rollers 21 are connected by a chain. One set of aeration rollers 21 is also connected to a drive motor A214. An air distribution groove 215 is provided on the outer wall of the aeration roller 21 in a reversing array. A radial passage 216 is also provided in the aeration roller 21 along a circular array. The radial passage 216 is connected to the axial passage 211 and the air distribution groove 215.

[0069] Each of the two sets of aeration rollers 21 at the edge is equipped with a set of drive sprockets A213, while each set of aeration rollers 21 in the middle is equipped with two sets of drive sprockets A213, so that the drive sprockets A213 on the adjacent two sets of aeration rollers 21 can be connected by a chain, thereby ensuring that the combination of each drive sprocket A213 and the chain has a sufficiently large wrap angle.

[0070] When the drive motor A214 is working, it can drive each set of aeration rollers 21 to operate stably, thereby driving the fabric 6 wrapped around it to be transported stably. High-temperature steam can be stably supplied to the axial passage 211 through the steam supply connector 212. When the aeration rollers 21 are rotating, high-temperature steam can always be transported to the axial passage 211, and then transported to the scouring and bleaching area 11 through the radial passage 216 and the air distribution groove 215. While heating the alkali solution and hydrogen peroxide to maintain their temperature, it can also limit the opening of the fabric 6 under pressure to facilitate efficient scouring and bleaching of the fabric 6.

[0071] To ensure that the lifting support 22 can drive the vibrating roller 23 to move back and forth vertically in the scouring and bleaching zone 11, thereby assisting in the efficient scouring and bleaching treatment of the fabric 6, the following technical solution is provided.

[0072] The practice area 11 is equipped with a guide seat 15. A guide shaft 221 is fixedly connected to the lifting bracket 22 and maintains a sliding combination with the guide seat 15. The guide shaft 221 is equipped with a return spring 222 at both ends, which abut against the lifting bracket 22 and the guide seat 15 respectively.

[0073] The practice float assembly 2 also includes multiple sets of camshafts 24 that are rotatably mounted to the practice float area 11 and arranged in the horizontal direction. The lifting bracket 22 is in contact with the camshafts 24. Each set of camshafts 24 has a transmission sprocket B241 fixedly connected to its end. Adjacent sets of transmission sprockets are connected by a chain. One set of camshafts 24 is also connected to a drive motor B242.

[0074] The cooperation between the guide seat 15 and the guide shaft 221 ensures that the lifting bracket 22 drives the vibrating wheel to move stably up and down in the vertical direction. When the drive motor drives each set of camshafts 24 to operate synchronously through the combination of the transmission sprocket B241 and the chain, the lifting bracket 22 and the vibrating roller 23 are driven to move up and down in the vertical direction in cooperation with the camshaft 24 and the return spring 222. While the vibrating roller 23 provides a guiding transmission function for the fabric 6, it can also periodically adjust the tension of the fabric 6 to better clean the pectin, wax and pigments attached to the fibers of the fabric 6.

[0075] Example 3

[0076] Please see Figure 2 , Figure 3 , Figure 7 To ensure that the cleaning component 3 can be stably assembled in the cleaning zone 12 and to realize the washing and dehydration treatment of the fabric 6 after scouring and bleaching, the following technical solution is provided.

[0077] The cleaning zone 12 is provided with multiple sets of sequentially arranged water storage tanks 16. The cleaning assembly 3 includes a cleaning roller 31, a drive roller 32, and a roller A33 arranged in each set of water storage tanks 16. The roller A33 is arranged on the upper and lower side of the water storage tank 16 and is used to dehydrate the fabric 6. The drive roller 32 is used to drive the fabric 6 to be continuously transported in each set of water storage tanks 16. The cleaning roller 31 is arranged in the water storage tank 16 and is used to clean the fabric 6.

[0078] High-temperature clean water is continuously supplied to the water storage tank 16. Multiple sets of water storage tanks 16 are used to continuously and in multiple steps clean the conveying fabric 6. The outer periphery of the cleaning roller 31 is equipped with bristles arranged in a reversing array. When the cleaning roller 31 operates, the bristles effectively contact the fabric 6 to clean away residual alkali and impurities. The rollers A33 are arranged in two parallel sets and are meshed together by reversing gears A331 to ensure that the two sets of rollers A33 always operate in opposite directions at the same speed, thereby effectively squeezing the fabric 6 passing through them to remove residual water adsorbed on the fabric 6.

[0079] To ensure the stable operation of the cleaning roller 31 and the transmission roller 32, so as to achieve effective transmission and cleaning of the fabric 6, the following technical solution is provided.

[0080] Each set of cleaning rollers 31 has a drive sprocket C311 fixedly connected to its end. The drive sprockets C311 on two adjacent sets of cleaning rollers 31 are connected by a chain. One set of cleaning rollers 31 is also connected to a drive motor C312. Each set of transmission rollers 32 has a drive sprocket D321 fixedly connected to its end. The drive sprockets D321 on two adjacent sets of transmission rollers 32 are connected by a chain. One set of transmission rollers 32 is also connected to a drive motor D322.

[0081] The transmission sprocket C311 and its associated chain C ensure that each group of cleaning rollers 31 always rotates in the same direction at the same speed, and the drive motor C312 drives each group of cleaning rollers 31 to operate stably, thereby achieving efficient cleaning of the fabric 6. The transmission sprocket D321 and its associated chain D ensure that each group of transmission rollers 32 always rotates in the same direction at the same speed, and the drive motor D322 drives each group of transmission rollers UN to operate stably, thereby achieving stable transfer of the fabric 6 in each group of water storage tanks 16.

[0082] Each roller A33 can be equipped with an independent motor drive, or it can be connected to the washing roller 31 or the transmission roller 32 through transmission components such as sprockets and belts, thereby driving each roller A33 to operate stably to achieve effective dehydration of the fabric 6.

[0083] Example 4

[0084] Please see Figure 2 , Figure 3 , Figure 8 To ensure that the dyeing assembly 4 can be stably assembled in the dyeing zone 13 and to effectively dye the fabric 6 transferred thereto, the following technical solution is provided.

[0085] The dyeing assembly 4 includes an upper support roller 41 and a lower support roller 42 rotatably mounted in the dyeing zone 13. Both the upper support roller 41 and the lower support roller 42 include multiple sets evenly arranged in the horizontal direction. The upper support roller 41 and the lower support roller 42 are arranged alternately in the horizontal direction. The end of each set of upper support roller 41 is fixedly connected to a transmission sprocket E411. The transmission sprockets E411 on two connected sets of upper support roller 41 are powered by a chain. One set of upper support roller 41 is also powered by a drive motor E412.

[0086] The arrangement of the upper support roller 41 and the lower support roller 42 can ensure that the fabric 6 transmitted to the dyeing zone 13 is stably supported, so as to ensure that the dye added in the dyeing zone 13 can fully immerse the fabric 6. Setting the upper support roller 41 and the lower support roller 42 at different height positions can ensure that the fabric 6 and the upper support roller 41 have sufficient wrap angle.

[0087] When the drive motor E412 operates and drives each set of upper support rollers 41 to operate stably and synchronously through the combination of the transmission sprocket E411 and the chain, it can drive the fabric 6 to move stably in the dyeing area 13.

[0088] To ensure the effective removal of excess dye from the dyed fabric 6, the following technical solution is provided.

[0089] Downstream of the dyeing zone 13, there is also a collection trough 17. The dyeing assembly 4 also includes multiple sets of rollers B43 assembled into the collection trough 17. The rollers B43 are used to remove excess dye from the fabric 6 and collect it into the collection trough 17.

[0090] Each set of rollers B43 is also provided with two pairs arranged side by side. The end of each roller B43 is fixed with a reversing gear B431. The reversing gears B431 on the two pairs of rollers B43 arranged side by side are connected by meshing to achieve the same speed and reverse rotation. They are also connected to the upper support roller 41 through a directly connected motor or transmission components such as sprockets and pulleys. After the dyed fabric 6 passes through the gap between the two pairs of rollers B43, the excess dye can be squeezed out and collected into the collection tank 17 under pressure.

[0091] Example 5

[0092] Please see Figure 2 , Figure 3 , Figure 9 , Figure 10 To ensure that the take-up and release assembly 5 can be stably assembled in the corresponding fabric storage area 14, and to adjust the take-up and release of the fabric 6 stored therein to cope with the speed difference in each processing assembly, the following technical solution is provided.

[0093] The take-up and release assembly 5 includes a sliding bracket 51, a movable roller 52, a fixed roller 53, and a hydraulic telescopic cylinder 54. Multiple sets of sliding brackets 51 arranged side by side are slidably installed in each set of fabric storage areas 14. The hydraulic telescopic cylinder 54 is fixedly installed on the mounting box 1 and maintains a power connection with the sliding brackets 51. Movable rollers 52 are rotatably installed on each set of sliding brackets 51. Fixed rollers 53 are rotatably installed in the fabric storage area 14. The fabric 6 is arranged sequentially around each set of movable rollers 52 and fixed rollers 53.

[0094] The fabric 6 can be arranged in an S-shape in multiple layers in the fabric storage area 14 to achieve effective storage of the fabric 6 in the fabric storage area 14, and under the guidance of the movable roller 52 and the fixed roller 53, the fabric 6 can be continuously and stably transported downstream in the fabric storage area 14.

[0095] When the hydraulic telescopic cylinder 54 extends or retracts, it can drive the sliding bracket 51 and the movable roller 52 to slide effectively within the stroke range, thereby causing the movable roller 52 to move closer to or away from the fixed roller 53. When the movable roller 52 moves closer to the fixed roller 53, it can reduce the amount of fabric 6 in the fabric storage area 14 to cope with the situation where the downstream component's operating speed is greater than the upstream component's operating speed.

[0096] To ensure the effective removal of excess residual liquid from the fabric 6 after scouring and bleaching, and to ensure efficient cleaning by the downstream cleaning components 3, the following technical solutions are provided.

[0097] A roller C55 is also rotatably installed in the fabric storage area 14 located on the side below the bleaching area 11. The roller C55 is arranged parallel to the fixed roller 53, and the fabric 6 passes through the gap between the roller C55 and the fixed roller 53.

[0098] Both the roll C55 and the corresponding fixed roll 53 are equipped with reversing gears C56 that maintain meshing connection, thereby ensuring that the roll C55 and the fixed roll 53 achieve equal speed and reverse rotation, and are powered by the aeration roll 21 through directly assembled motors or transmission components such as sprockets and pulleys, so as to effectively squeeze the fabric 6 and remove excess residual liquid.

[0099] In each area of ​​the mounting housing 1, there are also rotating guide rollers 18 to ensure that the fabric 6 is stably transmitted and flows in each area.

[0100] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
