Description

Technical Field

[0001] This invention relates to the field of blended fabric processing technology, and in particular to a dyeing and finishing process for wool and recycled polyester blended fabrics. Background Technology

[0002] Recycled polyester (recycled polyester fiber) is a fiber made from waste polyester materials through physical or chemical recycling processes. The wool and recycled polyester blended fabric dyeing and finishing process is a technique that blends wool and recycled polyester fibers, and then performs dyeing and finishing treatments through a series of processes. This process aims to combine the softness and warmth of wool with the abrasion resistance and quick-drying properties of recycled polyester to produce high-quality blended fabrics.

[0003] The dyeing and finishing process of wool and recycled polyester blended fabrics mainly includes three steps: pretreatment, dyeing, and finishing. Wool and recycled polyester blended fabrics are widely used in clothing, home textiles and other fields. This fabric not only retains the natural advantages of wool, such as softness and warmth, but also overcomes the disadvantages of pure wool fabrics, such as pilling and shrinkage, through blending, and enhances wrinkle resistance and abrasion resistance.

[0004] In existing technologies, to enhance the color diversity of wool and recycled polyester blended fabrics, it may be necessary to use different colored dyes to dye the wool and recycled polyester blended fibers during the dyeing process. Existing blended fabric dyeing and finishing processes typically employ fiber dyeing devices that generally include a frame, a dyeing cylinder fixed to the frame, a dyeing roller rotatably mounted inside the dyeing cylinder, a feed roller rotatably mounted on the frame and located on one side of the dyeing roller, a take-up roller rotatably mounted on the frame and located on the other side of the dyeing roller, and a pressure roller mounted on the frame and cooperating with the dyeing roller to press the fibers to be dyed. A drive component drives the take-up roller and dyeing roller to rotate, and the dyeing roller is dipped in dye from the dyeing cylinder to dye the fibers. However, the dyeing cylinder is usually large and difficult to adjust, and there is a tendency for dye to be wasted. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a dyeing and finishing process for wool and recycled polyester blended fabrics.

[0006] The above-mentioned technical objective of this invention is achieved through the following technical solution: a dyeing and finishing process for wool and recycled polyester blended fabrics, comprising the following steps: turning and sewing → singeing → desizing → scouring → bleaching → dyeing → washing → softening → setting; after dyeing the fibers, the dyed wool fibers and recycled polyester fibers are woven into a blended fabric; wherein, the dyeing step is performed using a fiber dyeing device, which includes a frame, a cylinder fixed on the frame, a dyeing roller rotatably mounted in the cylinder, a feeding roller rotatably mounted on the frame and located on one side of the cylinder, a take-up roller rotatably mounted on the frame and located on the other side of the cylinder, and a roller set on the machine... The frame is equipped with a lower pressure roller corresponding to the position of the dyeing roller. The frame is also equipped with a lifting assembly for controlling the lower pressure roller to press down and cooperate with the dyeing roller to press the fiber to be dyed, and a power assembly for controlling the rotation of both the dyeing roller and the take-up roller. A bottom plate is attached and fixed to the inner wall of the cylinder near its inner bottom wall. Flexible plate segments that abut against the inner wall of the cylinder are fixed at both ends of the bottom plate. A movable plate is fixed to the side of the flexible plate segment away from the bottom plate. The dyeing roller is located between the two movable plates. The bottom of the dyeing roller is located near the bottom plate. An adjustment mechanism is provided at the bottom of the cylinder for adjusting the angle between the movable plate and the bottom plate. A sealing assembly is provided on the movable plate to maintain the seal between it and the inner wall of the cylinder.

[0007] By adopting the above technical solution, before dyeing the fibers, steps such as turning, singeing, desizing, scouring, and bleaching can remove impurities, sizing agents, and natural pigments from the fabric, leaving the fibers in a clean and fluffy state so that the dye can better penetrate and absorb during subsequent dyeing. The angle between the movable plate and the base plate can be adjusted by the adjustment mechanism. After the position of the movable plate is adjusted, the sealing component maintains the seal between the movable plate and the inner wall of the dyeing cylinder. In this application, the movable plate, flexible plate segment, base plate, and cylinder form an adjustable space for storing dye, which is convenient for workers to adjust according to different dyeing and finishing needs. This changes the problem of difficult-to-adjust the volume of the dyeing cylinder in traditional technologies, which leads to significant dye waste.

[0008] Furthermore, the cylinder body is provided in multiple ways and fits together. An L-shaped plate is fixed between the frame bodies on both sides of the machine frame, which abuts against the bottom of the multiple cylinder bodies. The adjustment mechanism includes an adjustment assembly, which is provided in two sets and is used to adjust the tilt angle of the two movable plates respectively. The adjustment assembly includes a threaded rod that passes through the bottom of the cylinder body and is rotatably connected to the cylinder body, a movable block that is sleeved on the threaded rod and threadedly connected, and a traction rod that is hinged to the side of the movable block and the movable plate that are close to each other. The adjustment mechanism also includes a transmission assembly for driving the two threaded rods corresponding to the same cylinder body to rotate synchronously, and a drive assembly for driving the threaded rods corresponding to different cylinder bodies to rotate synchronously.

[0009] By adopting the above technical solution, the staff can use the drive component to drive the threaded rods corresponding to different cylinders to rotate synchronously, and the transmission component can drive the two threaded rods corresponding to the same cylinder to rotate synchronously. Since the movable block is threadedly connected to the threaded rod, and the movable block is hinged to the movable plate through the traction rod, the traction rod pushes the movable plate to move around the flexible plate segment, thereby allowing the volume of the dye storage space enclosed by the movable plate, the flexible plate segment, the base plate and the cylinder to be adjusted according to the usage requirements.

[0010] Furthermore, the drive assembly includes a lower gear fixed to the lower end of the threaded rod, an electric push rod fixed to the frame, a C-shaped sleeve fixed to the bottom of the cylinder by a fixing rod, and a rack fixed to the push rod end of the electric push rod and slidingly engaged with the C-shaped sleeve. The rack meshes with multiple lower gears. The transmission assembly includes lower synchronous pulleys fixedly sleeved on the threaded rod. The number of lower synchronous pulleys is equal to the number of threaded rods and their positions correspond one-to-one. The transmission assembly also includes a lower synchronous belt for connecting and meshing with the lower synchronous pulleys corresponding to the same cylinder.

[0011] By adopting the above technical solution, when it is necessary to adjust the volume of the dye storage space inside the cylinder, the operator only needs to adjust the electric push rod and make the rack slide back and forth along the C-shaped sliding sleeve. This causes the multiple lower gears meshing with the rack and the threaded rods fixed to the lower gears to rotate. Under the combined action of the lower synchronous pulley and the lower synchronous belt, the multiple threaded rods rotate synchronously, thereby allowing the multiple movable blocks inside the cylinder to be raised and lowered, so as to adjust the tilt angle of the multiple movable plates. The volume of the dye storage space enclosed by the movable plates, flexible plate segments, bottom plate and cylinder can be adjusted according to the usage requirements.

[0012] Furthermore, a feed pipe is fixed and connected to the bottom plate, and the feed pipe passes through the bottom of the cylinder and is fitted with a clearance. A U-shaped groove is provided at the intersection between the top of the movable plate and the side walls on both sides of the movable plate. The sealing assembly includes a U-shaped airbag fixed to it and an air inlet pipe fixed and connected to the top of the U-shaped airbag. Both ends of the U-shaped airbag are closed and hollow inside. A solenoid valve is provided on the air inlet pipe. After the U-shaped airbag is inflated, the outer walls of the U-shaped airbags on both sides of the movable plate abut against the inner walls on both sides of the cylinder.

[0013] By adopting the above technical solution, when adjusting the tilt angle of the movable plate, the solenoid valve is adjusted to release air from the U-shaped airbag. After the angle of the movable plate is adjusted to a suitable degree, the air inlet pipe and the inside of the U-shaped airbag are inflated by the external inflation system, so that the outer wall of the bulging U-shaped airbag is pressed against the inner walls on both sides of the cylinder. This ensures the sealing of the dye storage space enclosed by the movable plate, flexible plate segment, bottom plate and cylinder, thereby improving the stability of the dye storage process.

[0014] Furthermore, an annular flexible ring is attached and fixed to the outer wall of the dyeing roller, and an annular groove is provided on the circumferential surface of the lower pressure roller.

[0015] By adopting the above technical solution, the annular flexible ring is made of flexible materials such as rubber, silicone, or sponge. The lower pressure roller cooperates with the dyeing roller and the annular flexible ring to press and compress the fibers to be dyed. The dye carried by the annular flexible ring can fully dye the fibers. The annular groove design helps to enhance the stability of the fiber dyeing process.

[0016] Furthermore, the lifting assembly includes a horizontal plate fixed to the top of the frame, a guide rod that passes through the horizontal plate and is clearance-fitted, an "I"-shaped plate located below the horizontal plate, a cylinder fixed to the horizontal plate for controlling the lifting of the "I"-shaped plate, and a mounting plate fixed to the bottom of the "I"-shaped plate. The mounting plates are arranged in pairs, and the number of pairs of mounting plates is equal to the number of lower pressure rollers and their positions correspond one-to-one. Multiple lower pressure rollers are connected and fixed in series by a concentric central rod, which passes through multiple pairs of mounting plates and is rotatably connected.

[0017] By adopting the above technical solution, adjusting the cylinder and extending the piston rod controls the downward movement of the "I"-shaped plate, mounting plate, and lower pressure roller. This causes the lower pressure roller to press down on the fiber filaments to be dyed until it engages with the annular flexible ring and presses the fiber filaments firmly, facilitating the dyeing process. Initially, the lower pressure roller is suspended, with a large distance between it and the annular flexible ring, expanding the operating space. This allows the operator to pass the fiber filaments released from the feed roller around the annular groove of the lower pressure roller, and then wind and secure them onto the take-up roller.

[0018] Furthermore, a rotating rod and a take-up rod are rotatably connected to the frame. The rotating rod is concentric with and fixed to multiple dyeing rollers. The number of take-up rollers is equal to the number of dyeing rollers and their positions correspond. The take-up rod is concentric with and fixed to multiple take-up rollers. The power assembly includes a fixed block fixed to the frame, a worm gear rotatably connected to and passing through the fixed block, a worm wheel fixedly sleeved on the rotating rod and meshing with the worm gear, a motor fixed to the fixed block and driving the worm gear to rotate, a driving synchronous pulley fixedly sleeved on the rotating rod, a driven synchronous pulley fixedly sleeved on the take-up rod, and an upper synchronous belt meshing with both the driven synchronous pulley and the driving synchronous pulley.

[0019] By adopting the above technical solution, after the motor works, it drives the worm to rotate, thereby causing the worm wheel meshing with the worm, the rotating rod fixed to the worm wheel, and the driving synchronous wheel fixed to the rotating rod to rotate. The driving synchronous wheel drives the driven synchronous wheel to rotate under the action of the upper synchronous belt, thereby causing the winding rod fixed to the driven synchronous wheel and the winding roller fixed to the winding rod to rotate, so that the winding roller can wind up the fiber filaments.

[0020] Furthermore, there are two bottom plates in the same cylinder, the number of dyeing rollers is equal to the number of bottom plates and their positions correspond, there are two rotating rods and they are symmetrically arranged, the number of central rods is equal to the number of rotating rods and their positions correspond, the central rods and rotating rods are driven by a gear assembly, the gear assembly includes a driving gear fixedly sleeved on the rotating rod and a driven gear fixedly sleeved on the central rod and meshing with the driving gear.

[0021] By adopting the above technical solution, after the motor works and the rotating rod rotates, the drive gear and the dyeing roller rotate synchronously with the rotating rod. When the cylinder controls the lower pressure roller to press against the annular flexible ring, the drive gear drives the driven gear meshing with it, the central rod fixed to the driven gear, and the lower pressure roller fixed to the central rod to rotate, so that the lower pressure roller cooperates with the dyeing roller and dyes the fiber filaments.

[0022] Furthermore, the rotating rod passes through the side wall of the cylinder and maintains a seal through a rotating shaft seal.

[0023] Furthermore, a feeding rod is rotatably connected to the frame, the number of feeding rollers is equal to the number of take-up rollers and their positions correspond, the feeding rod is concentric with and fixed to the multiple feeding rollers, the feeding rod includes a first auxiliary rod rotatably connected to the frame body and a first main rod connected to the first auxiliary rod through a first coupling, the take-up rod includes a second auxiliary rod rotatably connected to the frame body and a second main rod connected to the second auxiliary rod through a second coupling.

[0024] By adopting the above technical solution, once the fiber filaments on the feeding roller are finished being fed, the operator only needs to remove the first coupling and the first main rod to replace the feeding roller with a new feeding roller for the fiber filaments to be dyed. Similarly, once the fiber filaments on the take-up roller are finished being wound, the operator only needs to remove the second coupling and the second main rod to remove the take-up roller.

[0025] In summary, the present invention has the following beneficial effects: Before dyeing the fibers, the process involves steps such as turning, singeing, desizing, scouring, and bleaching to remove impurities, sizing agents, and natural pigments from the fabric, leaving the fibers in a clean and fluffy state so that the dye can penetrate and be absorbed better during subsequent dyeing. The angle between the movable plate and the base plate can be adjusted by the adjustment mechanism. After the position of the movable plate is adjusted, the sealing component can maintain the seal between the movable plate and the inner wall of the cylinder. In this application, the movable plate, flexible plate segment, base plate and cylinder form a space with adjustable volume for storing dye, which is convenient for workers to adjust according to different dyeing and finishing needs. This changes the phenomenon that the volume of the dyeing cylinder is difficult to adjust in traditional technology, resulting in a lot of dye waste. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-8 As shown in the embodiment of this application, a dyeing and finishing process for a wool and recycled polyester blended fabric is disclosed. The process steps are as follows: turning and sewing → singeing → desizing → scouring → bleaching → dyeing → washing → softening → setting. After dyeing the fibers, the dyed wool fibers and recycled polyester fibers are woven into a blended fabric. The dyeing step is performed using a fiber dyeing device, which includes a frame 1, a cylinder 2 fixed on the frame 1, a dyeing roller 3 rotatably installed in the cylinder 2, a feeding roller 4 rotatably installed on the frame 1 and located on one side of the cylinder 2, a take-up roller 5 rotatably installed on the frame 1 and located on the other side of the cylinder 2, and a lower pressure roller 6 set on the frame 1 and corresponding to the position of the dyeing roller 3. The frame 1 is provided with a mechanism for controlling the lower pressure roller 6 to press down to cooperate with the dyeing roller 3 and press the fibers to be dyed. The cylinder 2 includes a lifting assembly 7 and a power assembly 8 for controlling the rotation of both the dyeing roller 3 and the winding roller 5. A base plate 21 is attached and fixed to the inner wall of the cylinder 2 near its inner bottom wall. Flexible plate segments 22 that abut against the inner wall of the cylinder 2 are fixed at both ends of the base plate 21. A movable plate 23 is fixed to the side of the flexible plate segment 22 away from the base plate 21. The dyeing roller 3 is located between the two movable plates 23. The bottom of the dyeing roller 3 is located near the base plate 21. An adjustment mechanism 9 for adjusting the angle between the movable plate 23 and the base plate 21 is provided at the bottom of the cylinder 2 (this application can dye multiple fibers at the same time. For fibers with a large dye requirement, the cylinder 2 does not need to be adjusted accordingly, and the corresponding cylinder 2 does not need to be equipped with an adjustment mechanism 9). A sealing assembly 10 for maintaining the seal between the movable plate 23 and the inner wall of the cylinder 2 is provided on the movable plate 23.

[0030] Before dyeing the fibers, steps such as turning, singeing, desizing, scouring, and bleaching are performed to remove impurities, sizing agents, and natural pigments from the fabric, leaving the fibers clean and fluffy so that the dye can better penetrate and absorb during subsequent dyeing. The angle between the movable plate 23 and the base plate 21 can be adjusted by the adjusting mechanism 9. After the position of the movable plate 23 is adjusted, the sealing component 10 can maintain the seal between the movable plate 23 and the inner wall of the cylinder 2. In this application, the movable plate 23, the flexible plate segment 22, the base plate 21, and the cylinder 2 form a space with adjustable volume for storing dye, which is convenient for workers to adjust according to different dyeing and finishing needs. This changes the phenomenon in traditional technology where the volume of the dyeing cylinder 2 is difficult to adjust, resulting in a lot of dye waste.

[0031] The cylinder body 2 is provided in multiple ways and fits together. The frame body on both sides of the frame 1 is fixed with an L-shaped plate 11 that abuts against the bottom of the multiple cylinder bodies 2. The adjustment mechanism 9 includes an adjustment component 91. The adjustment component 91 is provided in two sets and is used to adjust the tilt angle of the two movable plates 23 respectively. The adjustment component 91 includes a threaded rod 911 that passes through the bottom of the cylinder body 2 and is rotatably connected to the cylinder body 2, a movable block 912 that is sleeved on the threaded rod 911 and threadedly connected, and a traction rod 913 that is hinged to the side of the movable block 912 and the movable plate 23 that are close to each other. The adjustment mechanism 9 also includes a transmission component 92 for driving the two threaded rods 911 corresponding to the same cylinder body 2 to rotate synchronously, and a drive component 93 for driving the threaded rods 911 corresponding to different cylinder bodies 2 to rotate synchronously.

[0032] The drive assembly 93 includes a lower gear 931 fixed to the lower end of the threaded rod 911, an electric push rod 932 fixed to the frame 1, a C-shaped sleeve 933 fixed to the bottom of the cylinder 2 by a fixing rod, and a rack 934 fixed to the push rod end of the electric push rod 932 and slidingly engaged with the C-shaped sleeve 933. The rack 934 meshes with multiple lower gears 931. The transmission assembly 92 includes a lower synchronous pulley 921 fixedly sleeved on the threaded rod 911. The number of lower synchronous pulleys 921 is equal to the number of threaded rods 911 and their positions correspond one-to-one. The transmission assembly 92 also includes a lower synchronous belt 922 for connecting and meshing with the lower synchronous pulleys 921 corresponding to the same cylinder 2.

[0033] When it is necessary to adjust the volume of the dye storage space inside the cylinder 2, the operator only needs to adjust the electric push rod 932 and make the rack 934 slide back and forth along the C-shaped sliding sleeve 933. This causes the multiple lower gears 931 meshing with the rack 934 and the threaded rods 911 fixed to the lower gears 931 to rotate. Under the combined action of the lower synchronous pulley 921 and the lower synchronous belt 922, the multiple threaded rods 911 rotate synchronously, thereby allowing the multiple movable blocks 912 inside the cylinder 2 to be raised and lowered, so as to adjust the tilt angle of the multiple movable plates 23. The volume of the dye storage space enclosed by the movable plates 23, the flexible plate segment 22, the base plate 21 and the cylinder 2 can be adjusted according to the usage requirements.

[0034] A feed pipe 211 is fixed and connected to the bottom plate 21. The feed pipe 211 passes through the bottom of the cylinder 2 and is clearance-fitted. A U-shaped groove 231 is provided at the intersection between the top of the movable plate 23 and the side walls on both sides of the movable plate 23. The sealing assembly 10 includes a U-shaped airbag 101 fixed thereto and an air inlet pipe 102 fixed and connected to the top of the U-shaped airbag 101. Both ends of the U-shaped airbag 101 are closed and hollow inside. A solenoid valve (not shown in the figure) is provided on the air inlet pipe 102. After the U-shaped airbag 101 is inflated, the outer walls of the U-shaped airbag 101 on both sides of the movable plate 23 abut against the inner walls on both sides of the cylinder 2.

[0035] When adjusting the tilt angle of the movable plate 23, the solenoid valve is adjusted to release air from the U-shaped airbag 101. After the angle of the movable plate 23 is adjusted to a suitable degree, the air inlet pipe 102 and the inside of the U-shaped airbag 101 are inflated by the external inflation system, so that the outer wall of the bulging U-shaped airbag 101 is pressed against the inner walls on both sides of the cylinder 2. This ensures the sealing of the dye storage space enclosed by the movable plate 23, the flexible plate segment 22, the bottom plate 21 and the cylinder 2, thereby improving the stability of the dye storage process.

[0036] An annular flexible ring 31 is attached and fixed to the outer wall of the dyeing roller 3, and an annular groove 61 is provided on the circumferential surface of the lower pressure roller 6. The annular flexible ring 31 is made of flexible material, such as rubber, silicone, or sponge. The lower pressure roller 6 cooperates with the dyeing roller 3 and the annular flexible ring 31 to press the fiber filaments to be dyed. The dye carried by the annular flexible ring 31 can fully dye the fiber filaments. The annular groove 61 helps to enhance the stability of the fiber dyeing process.

[0037] The lifting assembly 7 includes a horizontal plate 71 fixed to the frame 1 near its top, a guide rod 72 passing through the horizontal plate 71 and with clearance fitting, an "I"-shaped plate 73 located below the horizontal plate 71, a cylinder 74 fixed to the horizontal plate 71 and used to control the lifting of the "I"-shaped plate 73, and a mounting plate 75 fixed to the bottom of the "I"-shaped plate 73. The mounting plates 75 are arranged in pairs, and the number of pairs of mounting plates 75 is equal to the number of lower pressure rollers 6 and their positions correspond one-to-one. Multiple lower pressure rollers 6 are connected in series and fixed by a concentric central rod 62, which passes through multiple pairs of mounting plates 75 and is rotatably connected.

[0038] After adjusting the cylinder 74 and extending the piston rod, the "I"-shaped plate 73, the mounting plate 75, and the lower pressure roller 6 can be controlled to move downwards. This causes the lower pressure roller 6 to press down on the fiber filaments to be dyed until it engages with the annular flexible ring 31 and presses the fiber filaments tightly, thus facilitating the dyeing operation. In the initial state, the lower pressure roller 6 is suspended, with a large distance between it and the annular flexible ring 31, expanding the operating space. This allows the operator to pass the fiber filaments released from the feed roller 4 around the annular groove 61 of the lower pressure roller 6, and then wind and fix them onto the take-up roller 5.

[0039] A rotating rod 12 and a take-up rod 51 are rotatably connected to the frame 1. The rotating rod 12 is concentric with and fixed to multiple dyeing rollers 3. The number of take-up rollers 5 is equal to the number of dyeing rollers 3 and their positions correspond. The take-up rod 51 is concentric with and fixed to multiple take-up rollers 5. The power assembly 8 includes a fixed block 81 fixed to the frame 1, a worm gear 82 rotatably connected to the fixed block 81, a worm wheel 83 fixedly sleeved on the rotating rod 12 and meshing with the worm gear 82, a motor 84 fixed to the fixed block 81 and driving the worm gear 82 to rotate, a driving synchronous pulley 85 fixedly sleeved on the rotating rod 12, a driven synchronous pulley 86 fixedly sleeved on the take-up rod 51, and an upper synchronous belt 87 meshing with both the driven synchronous pulley 86 and the driving synchronous pulley 85.

[0040] After the motor 84 starts working, it drives the worm gear 82 to rotate, which causes the worm wheel 83 meshing with the worm gear 82, the rotating rod 12 fixed to the worm wheel 83, and the driving synchronous wheel 85 fixed to the rotating rod 12 to rotate. The driving synchronous wheel 85 drives the driven synchronous wheel 86 to rotate under the action of the upper synchronous belt 87, which causes the winding rod 51 fixed to the driven synchronous wheel 86 and the winding roller 5 fixed to the winding rod 51 to rotate, so that the winding roller 5 can wind up the fiber filaments.

[0041] There are two bottom plates 21 in the same cylinder 2. The number of dyeing rollers 3 is equal to the number of bottom plates 21 and their positions correspond. There are two rotating rods 12 and they are arranged symmetrically. The number of central rods 62 is equal to the number of rotating rods 12 and their positions correspond. The central rods 62 and rotating rods 12 are driven by a gear assembly 13. The gear assembly 13 includes a driving gear 131 fixedly sleeved on the rotating rod 12 and a driven gear 132 fixedly sleeved on the central rod 62 and meshing with the driving gear 131.

[0042] After the motor 84 starts working and causes the rotating rod 12 to rotate, the drive gear 131 and the dyeing roller 3 rotate synchronously with the rotating rod 12. When the cylinder 74 controls the lower pressure roller 6 to press against the annular flexible ring 31, the drive gear 131 drives the driven gear 132 meshing with it, the central rod 62 fixed to the driven gear 132, and the lower pressure roller 6 fixed to the central rod 62 to rotate, so that the lower pressure roller 6 cooperates with the dyeing roller 3 and dyes the fiber filaments.

[0043] In this embodiment, the rotating rod 12 passes through the side wall of the cylinder 2 and is kept sealed by the rotating shaft seal 14, so that the rotating rod 12 and the cylinder 2 are kept sealed, reducing the probability of different dyes in adjacent cylinders 2 contaminating each other due to the fluctuation of dye liquid level during the rotation of the dyeing roller 3.

[0044] A feeding rod 41 is rotatably connected to the frame 1. The number of feeding rollers 4 is equal to the number of take-up rollers 5 and their positions correspond. The feeding rod 41 is concentric with and fixed to the multiple feeding rollers 4. The feeding rod 41 includes a first auxiliary rod 411 rotatably connected to the frame body of the frame 1 and a first main rod 412 connected to the first auxiliary rod 411 through a first coupling 15. The take-up rod 51 includes a second auxiliary rod 511 rotatably connected to the frame body of the frame 1 and a second main rod 512 connected to the second auxiliary rod 511 through a second coupling 16.

[0045] Once the fiber filaments on the feed roller 4 have been fed out, the operator only needs to remove the first coupling 15 and the first main rod 412 to replace the feed roller 4 with a new feed roller 4 containing the new fiber filaments to be dyed. Similarly, once the fiber filaments on the take-up roller 5 have been wound up, the operator only needs to remove the second coupling 16 and the second main rod 512 to remove the take-up roller 5.

[0046] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
