Description

Technical Field

[0001] The invention relates to the technical field of textile printing and dyeing production, in particular to a continuous dyeing and finishing device and a dyeing and finishing process for colored cotton fabrics. Background Art

[0002] A continuous dyeing and finishing device for colored cotton fabrics is a high-efficiency equipment designed specifically for dyeing and finishing cotton fabrics. The main function of the device is to achieve continuous and uniform dyeing of cotton fabrics and to perform necessary finishing during the dyeing process to improve the quality, appearance and performance of the cotton fabrics. Specifically, the continuous dyeing and finishing device introduces the cotton fabric into the dyeing tank in a continuous manner through a series of carefully designed components and mechanisms. In the dyeing tank, the cotton fabric is in full contact with the dyeing liquid, and the pigment in the dyeing liquid gradually penetrates into the fibers of the cotton fabric, so that it obtains the desired color.

[0003] In the dyeing and finishing process of cotton yarn, initial wetting is a crucial step, which lays a solid foundation for the subsequent dyeing process. However, when the traditional dyeing and finishing device uses a nozzle to spray liquid on the cotton yarn, although it can achieve a basic wetting effect, it exposes some limitations in actual operation. Specifically, the spray speed of the traditional device is often constant, which makes it difficult to adjust in real time according to the actual forward speed of the cotton yarn on the roller. When the forward speed of the cotton yarn is too fast or too low, the contact time and coverage area of the spray volume with the cotton yarn will change, resulting in the wetness of the liquid on the cotton yarn surface. Inconsistency. This uneven wetness will cause uneven dyeing effect in the later dyeing process, affecting the overall appearance and quality of the fabric. In addition, the traditional dyeing and finishing device also has a relatively simple way of processing cotton yarn in the dyeing tank. In most cases, the cotton yarn simply passes through the dyeing tank in a straight line. When the size of the dyeing tank is constant, if you want to increase the contact time between the dyeing liquid and the cotton yarn, you can only do so by reducing the forward speed of the cotton yarn. However, when a large amount of dyeing and finishing work needs to be done, this speed reduction approach will undoubtedly greatly reduce the working efficiency of the device and affect production progress and capacity.

[0004] Furthermore, we disclose a continuous dyeing and finishing device and dyeing and finishing process for colored cotton fabrics to solve the problems in the prior art of being unable to adjust the spray speed in real time and insufficient contact time of the cotton yarn in the dyeing tank resulting in uneven dyeing and low work efficiency.

[0015] A continuous dyeing and finishing process for colored cotton fabrics, using the above-mentioned continuous dyeing and finishing device for colored cotton fabrics, comprises the following steps: S1: Check whether the sprinkler assembly, adjustment assembly, and shaking assembly are installed correctly and connected firmly. Pass the cotton yarn through the three wheels in the adjustment assembly according to the set path and inject an appropriate amount of dyeing liquid into the dyeing tank. S2: Start the first cylinder, and drive the support seat to move up and down through its output end, adjust the tension of the cotton thread, and ensure that the cotton thread fits on the outer wall of the sprinkler wheel and can move with it when the sprinkler wheel rotates; S3: Start the second cylinder, and its output end pushes the fixed block downward, driving the pressure rod to move downward. The pressure rod pushes the pressure plate downward to compress the return spring. The lever rotates under the constraints of the sliding sleeve and the connecting rod, pushing the rotating rods on both sides to move upward. The center point between the three rotating rods changes in height, forming an inverted equilateral triangle.

At the same time, because the degree of deflection of the rotating plate is related to the rotation speed of the watering wheel, and the rotation speed of the watering wheel is directly related to the movement speed of the cotton yarn, the watering assembly can adjust the spray volume in real time according to the dyeing and finishing speed of the cotton yarn, ensuring uniform and consistent wetness on the surface of the cotton yarn, effectively solving the problem of uneven dyeing caused by the inability to adjust the spray speed in real time in traditional devices. In addition, the watering assembly has a simple and reliable structure and is easy to maintain and service, reducing production costs and difficulty of use.

[0017] An adjustment component is provided, which realizes dynamic adjustment of the positions of the three rotating rods through a second cylinder and a series of mechanical transmission mechanisms, so that the length of the cotton thread can be increased when the size of the dyeing tank remains constant. This design effectively solves the problem that in traditional dyeing and finishing devices, the cotton thread advances slowly in the dyeing tank in order to ensure the contact time, thereby reducing the working efficiency of the device. By increasing the length of the cotton thread in the dyeing liquid, the contact time between the dyeing liquid and the cotton thread can be extended, and the dyeing effect can be improved. At the same time, the structure of the adjustment component is relatively simple and the operation is convenient. It can adjust the length of the cotton thread in the dyeing tank according to actual needs, and has high flexibility and practicality. In addition, the adjustment component can also be used in conjunction with the shaking component to jointly improve the overall performance and dyeing effect of the dyeing and finishing device.

[0018] A shaking component is provided, which produces an effective shaking effect through the movement of the push plate, so that the dyeing liquid in the dyeing pool can be kept uniform, avoiding the occurrence of pigment deposition. This design effectively improves the utilization rate of the dyeing liquid, so that the cotton fabric can absorb the dyeing liquid more evenly, and improves the dyeing effect. At the same time, the structure of the shaking component is relatively simple, the operation is reliable, and the maintenance is convenient, which reduces the operating cost of the dyeing and finishing device.

[0024] like Figures 1 to 8 As shown, a continuous dyeing and finishing device for colored cotton fabrics includes a dyeing tank 1 filled with dyeing liquid, a bracket 2 fixedly connected to one side of the upper end surface of the dyeing tank 1, and a watering assembly provided on the bracket 2 for wetting the surface of the cotton yarn, an adjustment assembly provided in the inner middle portion of the dyeing tank 1 for increasing the length of the cotton yarn in the dyeing liquid, a shaking assembly provided at the lower end of the inner middle portion of the dyeing tank 1 for shaking the dyeing liquid in the dyeing tank 1, and a drain pipe 8 for draining liquid provided in the middle portion of the lower end surface of the dyeing tank 1; The continuous dyeing and finishing device for colored cotton fabrics greatly improves the dyeing and finishing efficiency and dyeing effect. First, the device is provided with a watering assembly, which drives the watering wheel 7 to rotate through the movement of the cotton yarn, and uses centrifugal force to deflect the rotating plate 10 to realize automatic spraying of the liquid. It is energy-saving and efficient and can adjust the spraying amount in real time according to the dyeing and finishing speed of the cotton yarn, ensuring that the surface wetness of the cotton yarn is uniform and consistent, effectively solving the problem of uneven dyeing in traditional devices. Secondly, the device is equipped with an adjustment assembly, which dynamically adjusts the position of the three rotating rods 18 through the second cylinder 9 and a series of mechanical transmission mechanisms, so that the length of the cotton yarn can be increased and extended when the size of the dyeing tank 1 is constant. The contact time between the dyeing liquid and the cotton yarn is prolonged, and the dyeing effect is improved. At the same time, the component has a simple structure, easy operation, and high flexibility and practicality. Finally, the device is also provided with a shaking component, which produces a shaking effect through the movement of the push plate 15, keeps the dyeing liquid uniform, avoids pigment deposition, and improves the utilization rate of the dyeing liquid and the dyeing effect. The shaking component is used in conjunction with the adjustment component to further improve the overall performance and dyeing efficiency of the dyeing and finishing device, and provide strong support for the continuous dyeing and finishing production of colored cotton fabrics. These innovative designs not only reduce production costs and difficulty of use, but also significantly improve the working efficiency and dyeing quality of the dyeing and finishing device.

[0025] Further, such as Figures 1 to 5 As shown, a first cylinder 3 is provided on one side of the middle of the bracket 2, and the output end of the first cylinder 3 passes through the bracket 2 and is fixedly connected to the support base 4. A through hole 11 is opened in the middle of the support base 4, and the sprinkler assembly includes a sprinkler wheel 7 that is engaged and rotatably connected to one side of the support base 4. The sprinkler wheel 7 is located at one end of the support base 4 and is fixedly connected to a clamping block 12. The sprinkler wheel 7 is engaged and rotatably connected to the support base 4 through the clamping block 12. The middle part of the outer wall of the sprinkler wheel 7 is in an inner arc shape, and a plurality of rotating plates 10 are evenly spaced and rotatably connected to the middle part of the outer wall of the sprinkler wheel 7. The rotating plate 10 is crescent-shaped, and the outer wall of the rotating plate 10 is Both ends of the side are fixedly connected with a rotating shaft 13, and the rotating plate 10 is rotatably connected to the sprinkler wheel 7 through the rotating shaft 13. A torsion spring 14 is provided at the connection between the rotating shaft 13 and the sprinkler wheel 7. The outer corners of the rotating plate 10 are provided with rounded corners. The rounded corners can ensure that the rotating plate 10 is sealed when it is not rotating and does not affect the normal rotation of the rotating plate 10. The end face of the support seat 4 away from the sprinkler wheel 7 is fixedly connected with a delivery pipe 5. The delivery pipe 5 is connected to the sprinkler wheel 7 through a through hole 11. The outer wall of the delivery pipe 5 is provided with a sliding block 6 at the connection between the bracket 2, and the sliding block 6 is slidably connected to the bracket 2; When in use, the cotton thread is attached to the outer wall of the watering wheel 7 and the support seat 4 is driven up and down by the first cylinder 3 to adjust the tension of the cotton thread. When the cotton thread moves forward with the movement of the production line, it will drive the watering wheel 7 to start rotating. Since the middle part of the outer wall of the watering wheel 7 is designed with an inner arc, and multiple crescent-shaped rotating plates 10 are evenly spaced and connected to the outer wall, when the watering wheel 7 rotates, the rotating plates 10 will be deflected by the centrifugal force. These rotating plates 10 are rotatably connected to the watering wheel 7 through the rotating shaft 13. , and a torsion spring 14 is sleeved at the connection. The function of the torsion spring 14 is to provide a restoring force after the rotating plate 10 is deflected by centrifugal force, so that the rotating plate 10 can quickly return to its position when the centrifugal force disappears. At the same time, the delivery pipe 5 is connected to the sprinkler wheel 7 through the through hole 11 on the support seat 4 to deliver the liquid to the inside of the sprinkler wheel 7. When the rotating plate 10 is deflected by centrifugal force, the liquid will leak out through the gap between the rotating plate 10 and the outer wall of the sprinkler wheel 7 and spray onto the cotton thread attached to the sprinkler wheel 7, thereby achieving the wetting of the cotton thread.

[0026] Further, such as Figures 6 and 7 As shown, the adjustment component includes three rotating rods 18 arranged in the middle of the dyeing tank 1, and the middle parts of the three rotating rods 18 are fixedly connected to the rotating wheel 21. The center points of the three rotating rods 18 are connected to form an equilateral triangle, and the rotating rod 18 in the middle is located above the other two rotating rods 18. Both ends of the rotating rod 18 are engaged and rotatably connected with sliders 29. Slide grooves 17 are provided on both sides of the inner wall of the dyeing tank 1. The side of the slider 29 away from the rotating rod 18 is slidably connected to the dyeing tank 1 through the slide groove 17. The lower end of the slider 29 is fixedly connected to a telescopic spring 28, and the lower end of the telescopic spring 28 is fixedly connected to the inner bottom surface of the dyeing tank 1. The adjustment component also includes a support plate 16 fixedly connected to one side of the middle part of the upper end surface of the dyeing tank 1, and a second Cylinder 9, the output end of the second cylinder 9 passes through the support plate 16 and is fixedly connected to a fixed block 19, the fixed block 19 is sleeved on the rotating rod 18 located in the middle, and the middle part of the lower end surface of the fixed block 19 is fixedly connected to a pressure rod 20, and the inner bottom surface of the dyeing tank 1 is fixedly connected to a return spring 26 at the lower end position of the pressure rod 20, and the upper end of the return spring 26 is fixedly connected to a pressure plate 22, and both ends of the pressure plate 22 are rotatably connected to a shift rod 23, and the middle outer walls of the two shift rods 23 are slidably connected to a sliding sleeve 25, and one side of the sliding sleeve 25 is engaged and rotatably connected to a connecting rod 24, and the end of the connecting rod 24 away from the sliding sleeve 25 is fixedly connected to the dyeing tank 1, and the ends of the two shift rods 23 away from the pressure plate 22 are respectively arranged at the lower ends of the rotating rods 18 on both sides and conflict with the rotating rods 18; When in use, the cotton thread is first passed through the three rotating wheels 21 according to the set path. The three rotating wheels 21 are respectively fixed to the middle parts of the three rotating rods 18. In the initial state, the center points of the three rotating rods 18 are connected to form an equilateral triangle. Then, the second cylinder 9 is started, and its output end pushes the fixed block 19 to move downward. The fixed block 19 is sleeved on the rotating rod 18 located in the middle and moves downward accordingly, driving the pressure rod 20 to move downward as well. The lower end of the pressure rod 20 conflicts with the pressure plate 22 connected to the return spring 26, and pushes the pressure plate 22 downward to compress the return spring 26. Both ends of the pressure plate 22 are rotatably connected to the driving rod 23, and the middle outer wall of the driving rod 23 is slidably connected to the sliding sleeve 25. One side of the sliding sleeve 25 is engaged and rotatably connected to the connecting rod 24. The connecting rod 24 is fixedly connected to the dyeing tank 1, and when the pressing plate 22 moves downward, the driving rod 23 rotates under the constraints of the sliding sleeve 25 and the connecting rod 24. The end thereof away from the pressing plate 22 will move outwards and contact the lower ends of the rotating rods 18 on both sides. Since the driving rod 23 conflicts with the rotating rod 18, the rotation of the driving rod 23 will push the rotating rods 18 on both sides to move upwards, that is, slide along the slide groove 17. At the same time, the slider 29 slides on the rotating rod 18 and compresses the telescopic spring 28. In this way, the center point heights between the three rotating rods 18 are all changed. After adjustment, the center points of the three rotating rods 18 become an inverted equilateral triangle. However, since they are still connected to the cotton thread through the rotating wheel 21, and the rotating wheel 21 can rotate around the rotating rod 18, the cotton thread will be tightened and form a larger arc, thereby increasing the length in the dyeing liquid. When the second cylinder 9 stops working, the return spring 26 will push the pressing plate 22 to move upwards, and the driving rod 23 will rotate accordingly and release the pressure on the rotating rod 18. The rotating rod 18 returns to its initial position under the action of the telescopic spring 28.

[0027] Further, such as Figure 8 As shown, the shaking assembly includes two push plates 15 arranged on both sides of the middle part of the bottom surface of the dyeing tank 1, the lower end surface of the push plate 15 fits with the inner bottom surface of the dyeing tank 1, and the cross-section of the push plate 15 is in the shape of an arch bridge. The middle parts of the upper end surfaces of the two push plates 15 are fixedly connected to a movable plate 30, and one end surface of the movable plate 30 is fixedly connected to a connecting spring 32. The end of the connecting spring 32 away from the movable plate 30 is fixedly connected to the dyeing tank 1, and the end of the movable plate 30 away from the connecting spring 32 is fixedly connected to a triangular plate 33. The end surface of the triangular plate 33 away from the connecting spring 32 is inclined. The shaking assembly also includes a fixed rod 27 fixedly connected to one side of the middle part of the pressure plate 22, and the lower end of the fixed rod 27 is rotatably connected to a roller 31. The outer wall of the roller 31 conflicts with the inclined surface of the triangular plate 33, and the inclined surface of the triangular plate 33 is located on both sides of the roller 31 and is fixedly connected to a limit strip to limit the roller 31. The shaking assembly mainly relies on the cooperation of the pushing plate 15, the movable plate 30, the connecting spring 32, the triangular plate 33, the fixed rod 27 and the roller 31. During the dyeing process, when the pressure plate 22 in the adjustment assembly moves up and down, the fixed rod 27 fixedly connected to one side of the middle of the pressure plate 22 will also move up and down accordingly. The lower end of the fixed rod 27 is rotatably connected to the roller 31, and the outer wall of the roller 31 conflicts with the inclined surface of the triangular plate 33. When the pressure plate 22 moves down, the fixed rod 27 also moves downward. The roller 31 rolls downward along the inclined surface of the triangular plate 33, generating a thrust to one side on the triangular plate 33, causing the triangular plate 33 to move to that side. The triangular plate 33 is fixedly connected to the movable plate 30, so that the movable plate 30 will also move to the same side, and at the same time compress the connecting spring 32 to store elastic potential energy. When the handle 31 is moved, the fixed rod 27 also moves upward, and the roller 31 rolls upward along the inclined surface of the triangular plate 33. At this time, the connecting spring 32 releases the stored elastic potential energy, pushing the movable plate 30 to move in the opposite direction to complete the reset. The movement of the movable plate 30 drives the two push plates 15 with an arch bridge-shaped cross-section to move on the bottom surface of the dyeing tank 1. The movement of the push plates 15 produces a shaking effect, which disturbs the dyeing liquid in the dyeing tank 1, thereby avoiding the deposition of pigment in the dyeing tank 1 and ensuring the uniformity of the dyeing liquid. At the same time, the existence of the limit bar ensures that the roller 31 will not separate from the inclined surface of the triangular plate 33 during the rolling process, thereby ensuring the stable operation of the shaking component. In actual use, the lower end of the dyeing tank 1 will be set to a cone for the convenience of discharging, and the lower end of the push plate 15 should also fit the lower end inner wall of the dyeing tank 1.

[0028] An embodiment of the present invention further provides a continuous dyeing and finishing process for colored cotton fabrics, which uses the above-mentioned continuous dyeing and finishing device for colored cotton fabrics, comprising the following steps: S1: Check whether the sprinkler assembly, adjustment assembly and shaking assembly are installed correctly and connected firmly, pass the cotton yarn through the three wheels 21 in the adjustment assembly according to the set path, and inject an appropriate amount of dyeing liquid into the dyeing tank 1; S2: Start the first cylinder 3, and drive the support base 4 to move up and down through its output end, adjust the tension of the cotton thread, and ensure that the cotton thread fits on the outer wall of the watering wheel 7 and can move with it when the watering wheel 7 rotates; S3: Start the second air cylinder 9, and its output end pushes the fixed block 19 to move downward, driving the pressure rod 20 to move downward as well. The pressure rod 20 pushes the pressure plate 22 downward to compress the return spring 26. The shifting rod 23 rotates under the constraints of the sliding sleeve 25 and the connecting rod 24, pushing the rotating rods 18 on both sides to move upward. The center point height between the three rotating rods 18 changes, forming an inverted equilateral triangle. The cotton yarn is tightened and forms a larger arc, increasing its length in the dyeing liquid. S4: During the dyeing process, when the pressing plate 22 in the adjustment assembly moves up and down, the fixed rod 27 fixedly connected to the pressing plate 22 also moves up and down. The roller 31 at the lower end of the fixed rod 27 rolls along the inclined surface of the triangular plate 33, pushing the triangular plate 33 and the movable plate 30 to move. The movement of the movable plate 30 drives the push plate 15 to move on the bottom surface of the dyeing tank 1, generating a shaking effect, so that the dyeing liquid remains uniform. S5: When the cotton yarn moves forward with the movement of the production line, it drives the watering wheel 7 to start rotating. When the watering wheel 7 rotates, the centrifugal force deflects the rotating plate 10, and the liquid leaks out through the gap between the rotating plate 10 and the outer wall of the watering wheel 7, and is sprayed onto the cotton yarn to achieve wetting; S6. The cotton yarn is fully contacted with the dyeing liquid and dyed. After dyeing is completed, the dyeing liquid in the dyeing tank 1 is discharged through the drain pipe 8.

[0029] The continuous dyeing and finishing process of colored cotton fabrics adopts the above-mentioned method, compared with the existing technology: by adjusting the coordinated work of the rotating wheel 21, the support seat 4 and the sprinkler wheel 7 in the component, the tension and position stability of the cotton thread during the dyeing process can be ensured, and the uniformity and consistency of the dyeing can be improved. Secondly, the pressure plate 22 and the rotating rod 18 mechanism driven by the second cylinder 9 can dynamically adjust the curvature of the cotton thread, increase its immersion length in the dyeing liquid, thereby improving the dyeing efficiency and effect. In addition, the shaking components driven by the pressure plate 22 when it moves up and down, such as the roller 31, the triangular plate 33 and the push plate 15, make the dyeing liquid uniform, avoiding the problems of dye precipitation and uneven concentration. Finally, the ingenious design of the sprinkler wheel 7 and the rotating plate 10 realizes continuous wetting of the cotton thread, further improving the permeability and fastness of the dyeing. In summary, this process step not only improves the dyeing quality, but also enhances production efficiency and stability, bringing significant technological progress to the textile dyeing industry.
