Description

Technical Field

[0001] This invention relates to the field of textile dyeing and finishing technology, and specifically to a continuous dyeing production line for filament bundles. Background Technology

[0002] Silk tow is an important form of semi-finished raw material in the textile industry. It is essentially a continuous, loose, parallel, and untwisted aggregate of fibers. Currently, in the textile industry, it is mainly used for dyeing garments, greige fabrics, and yarns, and to a lesser extent, for dyeing wool tops.

[0003] For example, a published Chinese patent, publication number CN206346028U, discloses a continuous dyeing apparatus. It includes a frame, on which a feeding mechanism, a padding mechanism, a drying mechanism, a washing mechanism, and a winding mechanism are sequentially arranged. The padding mechanism includes a padding tank for holding dye liquor, padding rollers, and a spray pipe. The padding tank is fixed to the frame, the padding rollers are rotatably disposed within the padding tank, and the spray pipe is disposed within the padding tank via a swinging structure that allows it to swing back and forth. The spray pipe is located below the padding rollers, and several outlets are opened on the side of the spray pipe, with the outlets facing upwards. One end of the spray pipe is closed, and the other end is connected to a conveying pump via a conveying pipe. The conveying pump is connected to a moving structure that allows it to move horizontally. The continuous dyeing device disclosed in this patent is designed for dyeing greige fabric. The final fabric formed after dyeing greige fabric is a uniform single color, and the color appears to be covered on the surface of the fabric. However, the final fabric formed after dyeing yarn usually needs to show a mixed color effect or yarn-dyed effect, such as checks or stripes, or be able to show a unique sense of color layering, such as denim, where the fabric color appears to be coming through the yarn. The continuous dyeing device disclosed in this patent uses a single box for color fixing and drying, which limits the post-processing length and the dwell time of the dyed product is insufficient, resulting in low dye molecule penetration and poor dyeing effect, which cannot meet the dyeing requirements of deep penetration and internal coloring of yarn. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a continuous dyeing production line for filament bundles, which solves the problem that the existing technology of using single-box color fixing and drying cannot meet the dyeing requirements of deep penetration and internal coloring of filament bundles.

[0005] To achieve the above and other related objectives, the present invention provides a continuous dyeing production line for filament bundles, the production line comprising a storage mechanism, a dyeing mechanism, a color-fixing mechanism, a washing mechanism, a softening mechanism, a drying mechanism, a cooling mechanism, and a stacking mechanism arranged sequentially along the transport direction of the filament bundles; The dyeing mechanism employs a dyeing pool, in which a pair of rotating dyeing rollers are provided, and the filament bundle is wound around the middle of the pair of dyeing rollers. The color-fixing mechanism employs multiple color-fixing boxes, each containing a microwave generator and a steam generator. Both the washing mechanism and the softening mechanism employ multiple processing tanks, each containing two squeezing rollers that rotate vertically in coordination. A drive motor is located on the outside of the processing tank, and the output of the drive motor is connected to one of the squeezing rollers. The drying mechanism employs multiple drying chambers, each equipped with an electric heater and a fan. The cooling mechanism employs multiple cooling boxes, each containing a cold air blower.

[0006] In one embodiment of the present invention, the dyeing pool is provided with a first driving device and a guide roller connected to the output end of the first driving device at one end near the fixing box. After the silk bundle is dyed, it is guided out by the rotation of the guide roller.

[0007] In one embodiment of the present invention, a feed inlet is provided at the upper end of the fixing box near the dyeing mechanism, and a guide roller is fitted directly above the feed inlet.

[0008] In one embodiment of the present invention, the color-fixing box is provided with a folding mechanism. The folding mechanism includes a second driving device, a rotating shaft connected to the output end of the second driving device, and a push rod disposed on the outer periphery of the rotating shaft. The second driving device is mounted on the outside of the color-fixing box, and the rotating shaft is rotatably mounted inside the color-fixing box through a bearing and is located directly below the feed inlet.

[0009] In one embodiment of the present invention, a first transmission mechanism is provided inside the plurality of color-fixing boxes. The first transmission mechanism includes a third driving device, a first driving pulley, a first driven pulley, and a first transmission belt. The first driving pulley and the first driven pulley are rotatably mounted in the color-fixing boxes located at the input end and the output end of the color-fixing mechanism, respectively. The third driving device is mounted outside the color-fixing box located at the input end of the color-fixing mechanism and its output end is connected to the first driving pulley. The first transmission belt is simultaneously sleeved on the first driving pulley and the first driven pulley.

[0010] In one embodiment of the present invention, the treatment tank is provided with a first guide roller, a second guide roller, and a third guide roller. The first guide roller and the second guide roller are fitted together below one side of the squeezing roller located at the lower end, and the third guide roller is fitted together below the other side of the squeezing roller located at the lower end.

[0011] In one embodiment of the present invention, the interiors of the plurality of drying chambers are sequentially connected to the interiors of the plurality of cooling chambers. A second transmission mechanism is provided in both the interiors of the plurality of drying chambers and the plurality of cooling chambers. The second transmission mechanism includes a fourth driving device, a second driving pulley, a second driven pulley, and a second transmission belt. The second driving pulley is rotatably mounted in the drying chamber located at the input end of the drying mechanism. The fourth driving device is mounted outside the drying chamber located at the input end of the drying mechanism and its output end is connected to the second driving pulley. The second driven pulley is rotatably mounted in the cooling chamber located at the output end of the cooling mechanism. The second transmission belt is simultaneously sleeved on the second driving pulley and the second driven pulley.

[0012] In one embodiment of the present invention, the hollow cylindrical fan has a hollow cylindrical air chamber that runs vertically through it, and the filament bundle runs through the hollow cylindrical air chamber.

[0013] In one embodiment of the present invention, both the input end of the drying mechanism and the output end of the cooling mechanism are provided with guide rollers.

[0014] In one embodiment of the present invention, the rotational speed of the rotating shaft is greater than the rotational speed of the guide roller, and the rotational speed of the guide roller is greater than the rotational speed of the first transmission mechanism.

[0015] As described above, the continuous dyeing production line for filaments of the present invention has the following beneficial effects: 1. In this invention, the color-fixing mechanism employs multiple interconnected color-fixing boxes, combined with the synergistic effect of a microwave generator and a steam generator to form a continuous, gradually changing temperature field, which promotes the deep penetration of dye molecules into the interior of the filament bundle. With the rotational folding design of the folding mechanism, the threading time of the filament bundle can be extended under the condition of the same color-fixing mechanism length, thereby extending the color-fixing time of the filament bundle and improving the color-fixing effect of the filament bundle. Compared with traditional single-box color-fixing, it significantly improves the color fastness and color uniformity, meeting the requirements of color mixing and layering of the woven fabric after dyeing the filament bundle. 2. In this invention, both the washing mechanism and the softening mechanism employ multiple treatment tanks. The washing mechanism can repeatedly wash and squeeze the filament bundle, extending the washing time and improving the washing effect. The softening mechanism can soften the filament bundle, improving the filament bundle treatment effect and facilitating the improvement of the quality of subsequent filament bundle-formed textile products. The treatment tank, through the cooperation of the first guide roller, the second guide roller, and the third guide roller, forms a treatment path that can lengthen the filament bundle in a single tank, extending the effective immersion time, reducing the residual rate of auxiliary agents, and improving the softening effect.

[0016] 3. The hollow cylindrical fan in this invention can control the water and disperse the washed filaments. The drying mechanism and the cooling mechanism share the second transmission mechanism, which can form a continuous temperature control chain of hot air gradient and cold air gradual, thereby improving the post-dyeing treatment effect of the filaments.

[0017] 4. This invention innovatively proposes a continuous dyeing production line for filament bundles. Through modular multi-box design, cross-process synchronous transmission, and temperature gradient control, it overcomes the deep penetration problem in continuous dyeing of filament bundles. This production line has no manual intervention breakpoints from material storage to stacking. Relying on the cross-box synchronous drive of the conveyor belt, it reduces the failure downtime rate and has significant industrial application value, enabling a breakthrough in full-process continuous operation.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0028] Please see Figures 1 to 8 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0029] Please see Figures 1-2 , Figure 8 This invention provides a continuous dyeing production line for filament bundles. The production line includes a storage mechanism 1, a dyeing mechanism 2, a color-fixing mechanism 3, a washing mechanism 4, a drying mechanism 5, a cooling mechanism 6, and a stacking mechanism 7 arranged sequentially along the transport direction of the filament bundles. The stacking mechanism 7 is equipped with a stacking trolley, and a swing arm is provided above the stacking trolley. After the filament bundles are discharged from the storage mechanism 1, they are sequentially dyed through the dyeing mechanism 2, the color-fixing mechanism 3, the washing mechanism 4, the drying mechanism 5, and the cooling mechanism 6. After dyeing, they are pulled into the stacking mechanism 7. The dyed filament bundles are stacked layer by layer on the stacking trolley by swinging the swing arm.

[0030] Please see Figures 3-4 The dyeing mechanism 2 employs a dyeing pool 21, within which a pair of rotating dyeing rollers 22 are installed. A filament bundle is wound around the middle of the pair of dyeing rollers 22. A hopper 13 is located on one side of the dyeing pool 21 for storing pigment. This invention includes two dyeing processes. In one process, dye liquor is placed in the dyeing pool 21, with the liquor level not lower than the lower end of the dyeing rollers 22. The filament bundle is fully immersed in the dye from the lower end of one of the dyeing rollers 22, and then the dye liquor is squeezed out from between the two dyeing rollers 22 to achieve dyeing. In the other process, a spraying device is used to hold the dye liquor, which is then sprayed onto the dyeing rollers 22. The filament bundle enters between the pair of dyeing rollers 22, is squeezed, and then fully contacts the dye to achieve dyeing.

[0031] The color-fixing mechanism 3 employs multiple color-fixing boxes 31, each of which is equipped with an independently controlled microwave generator 32 and a steam generator 33. The multiple color-fixing boxes 31 are interconnected. By independently setting the operating frequencies of the microwave generator 32 and the steam generator 33 in each color-fixing box 31, a continuous gradual temperature field can be formed. Continuous color fixing is achieved through the synergistic effect of microwaves and saturated steam, which promotes the deep penetration of dye molecules into the interior of the fiber bundle.

[0032] The dyeing tank 21 is equipped with a first driving device and a guide roller 23 connected to the output end of the first driving device at one end near the fixing box 31. After dyeing, the silk bundle is guided out by the rotation of the guide roller 23. The fixing box 31 near the dyeing mechanism 2 has a feed inlet 311 at its upper end, and the guide roller 23 is positioned directly above the feed inlet 311. The fixing box 31 is equipped with a folding mechanism 10, which includes a second driving device, a rotating shaft 101 connected to the output end of the second driving device, and push rods 102 disposed on the outer periphery of the rotating shaft 101. There are three push rods 102, which are equidistantly arranged around the outer periphery of the rotating shaft 101. The second driving device is mounted on the outside of the fixing box 31, and the rotating shaft 101 is rotatably mounted inside the fixing box 31 via bearings and is located directly below the feed inlet 311. A first transmission mechanism 8 is simultaneously provided inside multiple color-fixing boxes 31. The first transmission mechanism 8 includes a third driving device, a first driving pulley 81, a first driven pulley 82, and a first transmission belt 83. The first driving pulley 81 and the first driven pulley 82 are rotatably mounted in the color-fixing boxes 31 located at the input and output ends of the color-fixing mechanism 3, respectively. The third driving device is mounted outside the color-fixing box 31 located at the input end of the color-fixing mechanism 3, and its output end is connected to the first driving pulley 81. The first transmission belt 83 is simultaneously sleeved on the first driving pulley 81 and the first driven pulley 82. The rotational speed of the rotating shaft 101 is greater than the rotational speed of the guide roller 23, and the rotational speed of the guide roller 23 is greater than the rotational speed of the first transmission mechanism 8. After dyeing, the silk bundle is guided out by the rotation of the guide roller 23 and enters the color-fixing box 31 from the feed inlet 311. The rapid rotation of the guide roller 23 folds the filament bundle via the push rod 102 and continuously transmits it through the first transmission mechanism 8. Specifically, when the rotation speed of the guide roller 23 is equal to N times the rotation speed of the first transmission mechanism 8 (N is an integer, and 2 < N ≤ 30), the filament bundle can be folded up to N layers in the color-fixing mechanism 3. In the actual production line, the rotation speed of the guide roller 23 can be 30 times the rotation speed of the first transmission mechanism 8, N = 30, meaning the filament bundle can be folded up to 30 layers in the color-fixing mechanism 3, achieving a multi-layer folding effect. Under the condition of the same length of the color-fixing mechanism 3, the threading time of the filament bundle can be extended, thereby extending the color-fixing time of the filament bundle and improving the color-fixing effect of the filament bundle. Compared with the traditional single-box color-fixing, it significantly improves the color fastness and color uniformity, meeting the requirements of color mixing and layering of the woven fabric after dyeing the filament bundle.

[0033] Please see Figures 5-6 Both the washing mechanism 4 and the softening mechanism 14 employ multiple treatment tanks 41. Each treatment tank 41 contains two vertically rotating squeezing rollers 42. A drive motor 43 is located on the outside of each treatment tank 41, and its output is connected to one of the squeezing rollers 42. Each treatment tank 41 contains a first guide roller 44, a second guide roller 45, and a third guide roller 46. The first guide roller 44 and the second guide roller 45 are vertically aligned below one side of the lower squeezing roller 42, while the third guide roller 46 is positioned below the other side of the lower squeezing roller 42. Water flows through the treatment tank 41 via the first guide roller 44, the second guide roller 45, and the third guide roller 46. The second guide roller 45 and the third guide roller 46 work together to lengthen the processing path of the filament bundle in a single pool, extending the effective immersion time, reducing the residual rate of auxiliary agents, and improving the softening effect. The arrangement of multiple processing pools 41 allows for repeated washing and squeezing of the filament bundle, extending the washing time and improving the washing effect. In this embodiment, there are 6 processing pools 41. The 4 processing pools 41 closest to the color-fixing mechanism 3 contain washing products to form a washing environment, while the 2 processing pools 41 farther away from the color-fixing mechanism 3 contain softening products to form a softening environment, thereby improving the filament bundle processing effect and improving the quality of subsequent filament bundle-formed textile products.

[0034] Please see Figure 7 The input end of the drying mechanism 5 is equipped with a hollow cylindrical fan 12, which has a hollow cylindrical air chamber that runs vertically through it. The filament bundles pass through the hollow cylindrical air chamber. Specifically, the hollow cylindrical fan 12 also includes at least a motor and an impeller connected to the output end of the motor. Its working principle is based on the air compression technology of a centrifugal compressor. The motor drives the impeller to rotate at high speed. The impeller is designed to rotate at a high speed of up to 50,000 revolutions per minute to generate strong centrifugal force. Through centrifugal action, air is drawn in from the center and compressed and accelerated to the edge to form a high-speed airflow. The hollow cylindrical air chamber is equipped with an annular channel. After the impeller accelerates the drawn-in air to the edge, it uses Bernoulli's principle to blow the air out from the annular gap. The airflow circulates in the annular channel to achieve a continuous ventilation effect. The hollow cylindrical fan 12 is a commonly used industrial blower product, which will not be described in detail here. After washing, the filament bundles pass through the hollow cylindrical air chamber for water control and dispersion before entering the drying mechanism 5.

[0035] The drying mechanism 5 employs multiple drying chambers 51, each of which is equipped with an independently adjustable electric heater 52 and a fan. The electric heater 52 generates heat, and the fan forces hot air into the chamber to dry the filament bundle. The cooling mechanism 6 employs multiple cooling chambers 61, each of which is equipped with an independently adjustable cold air fan 62. The cold air fan 62 blows cold air out of the cooling chamber 61 to cool the filament bundle. Both the input end of the drying mechanism 5 and the output end of the cooling mechanism 6 are equipped with guide rollers 11, which facilitate the continuous conveying of the filament bundle. The interiors of the multiple drying chambers 51 are sequentially connected to the interiors of the multiple cooling chambers 61. A second transmission mechanism 9 is simultaneously provided inside both the drying chambers 51 and the cooling chambers 61. The second transmission mechanism 9 includes a fourth drive device, a second drive pulley 91, a second driven pulley 92, and a second transmission belt 93. The second drive pulley 91 is rotatably mounted in the drying chamber 51 located at the input end of the drying mechanism 5. The fourth drive device is mounted outside the drying chamber 51 located at the input end of the drying mechanism 5, and its output end is connected to the second drive pulley 91. The second driven pulley 92 is rotatably mounted in the cooling chamber 61 located at the output end of the cooling mechanism 6. The second transmission belt 93 is simultaneously fitted onto the second drive pulley 91 and the second driven pulley 92. The drying mechanism 5 and the cooling mechanism 6 share the second transmission mechanism 9, enabling the formation of a continuous temperature control chain with progressively increasing hot air gradients and gradually decreasing cold air, thus gradually cooling the filament bundle while drying it.

[0036] In this invention, the first driving device, the second driving device, the third driving device, and the fourth driving device are not shown in the accompanying drawings. However, those skilled in the art should know that the first driving device, the second driving device, the third driving device, and the fourth driving device can all use a rotary motor as the driving source.

[0037] In summary, this invention innovatively proposes a continuous dyeing production line for filament bundles. Through modular multi-box design, cross-process synchronous transmission, and temperature gradient control, it overcomes the challenge of deep penetration in continuous dyeing of filament bundles. This production line eliminates manual intervention points from material storage to stacking, and relies on cross-box synchronous drive via conveyor belts to reduce downtime due to malfunctions. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
