Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically a polyester filament dyeing device. Background Technology

[0002] Polyester filament, as an important textile raw material, is widely used in clothing, home textiles, and industrial fields. Its dyeing quality directly affects the color, fastness, and appearance of the final product. Traditional polyester filament dyeing processes typically include unwinding, dyeing, fixing, washing, drying, and rewinding. Each step is often completed by independent equipment, resulting in problems such as fragmented process flow, cumbersome operation, and low production efficiency. Furthermore, uneven yarn tension, uneven dyeing, or damage can easily occur during the transition between different processes.

[0003] Currently, most common polyester filament dyeing equipment adopts a combination of immersion dyeing and mechanical transmission, but in practical use, it still has the following shortcomings:

[0004] Poor dyeing uniformity: Insufficient circulation of dye liquor can easily lead to color spots or uneven dyeing, and impurities and suspended matter in the dye liquor can affect the surface quality of the silk thread.

[0005] Unstable color fixation effect: In the existing technology, after coloring, the yarn is usually wound up directly, and then the relevant color fixation operation is carried out. At this time, the polyester yarn is coiled together in layers, and it is difficult to achieve the effect on the innermost yarn when color fixing is performed.

[0006] Low cleaning efficiency: Traditional water washing methods are difficult to completely remove floating dye and impurities from inside the yarn, and the deep cleaning effect is limited, especially for multi-strand yarns.

[0007] High energy consumption and heavy pollution: Each link operates independently, resulting in low utilization rates of heat energy and water resources, and wastewater discharge lacks timely treatment, leading to a heavy environmental burden.

[0008] Low level of automation: The silk threads rely on manual adjustment during transmission, which can easily lead to problems such as tangling and knotting, affecting continuous production.

[0009] To address these issues, some integrated dyeing equipment has been attempted in the existing technology, such as combining dyeing and color-fixing functions or using ultrasonic-assisted cleaning. However, these devices often still have shortcomings in areas such as dye liquor filtration, heat recovery, and yarn path optimization, making it difficult to achieve efficient, energy-saving, and environmentally friendly continuous production while ensuring dyeing quality. Utility Model Content

[0010] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a polyester filament dyeing device with reasonable structure, integrated functions and convenient operation.

[0015] In the above technical solution, the cleaning mechanism includes a cleaning tank, an ultrasonic generator, a second guide roller, a second rotating shaft, and a second guide wheel. Support feet are fixedly connected to the four corners of the lower end of the cleaning tank. An ultrasonic generator is fixedly connected inside the cleaning tank.

[0016] In the above technical solution, the drying mechanism includes a drying box, a third guide roller, a third guide wheel, a warm air blower, and an exhaust pipe. Several third guide tubes are fixedly connected to the outer walls of both sides of the drying box. A third guide roller is fixedly connected to the drying box on one side of each third guide tube.

The drive motor is fixedly connected to one side of the upper end of the mounting block.

[0018] The beneficial effects of this utility model are:

[0019] This invention integrates multiple processes, including unwinding, dyeing, color fixing, washing, drying, and rewinding, into a single continuously operating device, achieving full automation and integration of the polyester filament dyeing process. This not only significantly reduces changeover time and material handling between processes, greatly improving production efficiency, but also effectively avoids yarn tension fluctuations, damage, or contamination caused by repeated manual handling, ensuring the continuity and stability of the production process.

[0020] Specifically, in the dyeing process, this invention designs a dyeing mechanism with dye liquor circulation and filtration functions. A liquid pump drives the dye liquor flow, which, combined with the wiring conduit, distributes the liquor evenly. Meanwhile, multi-layered, staggered guide rollers extend the immersion path and time of the yarn in the dye liquor. Simultaneously, the filter box effectively removes impurities and suspended matter from the dye liquor. These designs work together to ensure that the polyester yarn can fully and evenly contact the fresh dye liquor, thereby significantly improving the uniformity and color fastness of the dyeing process and effectively preventing quality problems such as uneven coloring and color difference.

[0021] Regarding the color-fixing process, this invention incorporates a separate color-fixing mechanism before washing and drying. This mechanism utilizes high-temperature steam to directly and uniformly fix the color of individual threads in their unfolded state, avoiding the uneven color-fixing effect between the inner and outer layers caused by the traditional process of first winding the threads into a ball before color fixing. This online color-fixing method ensures that heat and steam can fully act on each thread, thereby guaranteeing excellent overall color-fixing effect and consistent quality.

[0022] In the cleaning process, this invention introduces ultrasonic cleaning technology. The high-frequency vibrations generated by the ultrasonic generator create countless microbubbles in the cleaning solution. The impact force generated when these bubbles burst can penetrate deep into the polyester fibers, effectively peeling off and removing deeply attached floating dye and stubborn impurities. Compared with traditional water washing, this method is more thorough and efficient in cleaning, and does not damage the yarn itself, laying a solid foundation for subsequent drying and the high cleanliness of the final product.

[0023] This invention incorporates a warm air blower and a serpentine, meandering yarn path within the drying mechanism. The warm air blower provides continuous hot air, while the staggered arrangement of guide rollers and baffles extends the yarn's travel distance within the drying chamber and ensures thorough contact between the hot air and the yarn surface. This structure significantly improves thermal efficiency and accelerates moisture evaporation, achieving rapid and uniform drying while also reducing energy consumption per unit of product.

[0024] The entire device achieves fully automated continuous operation from unwinding to rewinding. Guided smoothly by pre-set guide rollers and wheels, the various mechanisms work in concert, greatly reducing reliance on manual adjustments. This not only reduces labor intensity and costs but also fundamentally avoids problems such as thread tangling, knotting, or breakage that can occur due to improper manual operation, ensuring the reliability and quality of large-scale continuous production.

[0025] In summary, this invention optimizes and integrates all functional modules of the dyeing process and introduces advanced technologies such as filtration circulation and ultrasonic cleaning to construct a highly efficient, stable, energy-saving, and automated polyester filament dyeing system. It not only significantly improves the dyeing quality and production efficiency of polyester filament but also offers excellent environmental friendliness and ease of operation, aligning with the intelligent and green development direction of the modern textile industry.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] Please see Figure 1-6A polyester filament dyeing device includes an unwinding mechanism 1, a dyeing mechanism 2, a color-fixing mechanism 3, a washing mechanism 4, a drying mechanism 5, and a winding mechanism 6 arranged sequentially along the filament travel direction. The unwinding mechanism 1 is used to draw out the polyester filament, which enters the dyeing mechanism 2 for immersion dyeing. Then, it passes through the color-fixing mechanism 3 for high-temperature steam color fixing. After color fixing, the filament enters the washing mechanism 4 to wash away deep floating dye and impurities. Next, the filament passes through the drying mechanism 5 to dry the moisture. Finally, the polyester filament is rewound by the winding mechanism 6.

[0035] In the above structure, the unwinding mechanism 1 includes a first rotating shaft frame 201, a first rotating shaft 202, and polyester filament reels 203. The first rotating shaft frame 201 is fixedly connected to both sides of the outer wall of the dyeing box 101. The first rotating shaft 202 is rotatably connected between the first rotating shaft frames 201. Several polyester filament reels 203 are slidably connected to the first rotating shaft 202. During operation, the winding mechanism 6 pulls and winds the polyester filament. Under the action of this force, the polyester filament in the polyester filament reel 203 is pulled out and rotated, thereby driving the first rotating shaft 202 to rotate on the first rotating shaft frame 201. The first rotating shaft frame 201 is a detachable design structure, so that the first rotating shaft 202 can be disassembled, thereby facilitating the replacement of the polyester filament reels 203.

[0036] In the above structure, the coloring mechanism 2 includes a dyeing box 101, a first guide roller 102, a first rotating shaft 103, a first guide wheel 104, a liquid pump 105, a filter box 106, and a filter layer 107. First guide tubes 108 are fixedly connected to the outer walls on both sides of the dyeing box 101. First guide rollers 102 are fixedly connected to the dyeing box 101 on one side of the first guide tube 108. Several first rotating shafts 103 are rotatably connected to the dyeing box 101 between the first guide rollers 102. The first rotating shafts 103 are arranged alternately up and down. Several first guide wheels 104 are fixedly connected to the first rotating shafts 103. A box cover plate 109 is provided at the upper end of the dyeing box 101. A filter box 106 is fixedly connected to the lower end of the box cover plate 109. Several filter holes 110 are opened at the lower end of the filter box 106. A filter layer 107 is provided at the bottom of the filter box 106. A wiring conduit 111 is fixedly connected inside the filter box 106 above the filter layer 107. One end of the wiring conduit 111 is fixedly connected to an infusion pipe 112. The infusion pipe 112 passes through the filter box 106 and the box cover plate 109 and is connected to the output end of the liquid pump 105. The liquid pump 105 is fixedly installed on one side of the dyeing box 101. The input end of the liquid pump 105 is connected to a suction pipe 113. The other end of the suction pipe 113 is connected to the bottom of the dyeing box 101. Its working principle is as follows: the polyester yarn passes through the first guide tube 108 on one side into the dyeing box 101, passes around the smooth first guide roller 102 and then passes around the first guide wheel 104 in sequence, so that the polyester yarn is repeatedly immersed in the dye liquor and its immersion time is extended, thereby improving the dyeing effect. Then it passes around the first guide roller 102 on the other side and passes through the first guide tube 108 on the other side out of the dyeing box 101.

[0037] In the above structure, the color-fixing mechanism 3 includes a high-temperature steaming chamber 301, an evaporator 302, a steam conduit 303, and a second guide wire tube 304. Support legs 305 are fixedly connected to the four corners of the lower end of the high-temperature steaming chamber 301. Several second guide wire tubes 304 are fixedly connected to the outer walls of both sides of the high-temperature steaming chamber 301. The evaporator 302 is fixedly connected to the middle of the lower end of the high-temperature steaming chamber 301. The evaporator 302 is connected to the bottom of the high-temperature steaming chamber through several steam pipes. A vent pipe 306 is fixedly connected to the upper end of the high-temperature steaming chamber, and a vent valve 307 is fixedly connected to the vent pipe 306. A drain pipe 308 is fixedly connected to one edge of the bottom of the high-temperature steaming chamber 301. During operation, the dyed polyester yarn flows from one side of the second guide wire tube... The polyester filaments 304 are inserted into the high-temperature steam chamber 301 and then exit from the second guide tube 304 on the other side. During this process, the evaporator 302 generates high-temperature steam and introduces it into the high-temperature steam chamber 301 through the steam conduit 303, so that the polyester filaments in the high-temperature steam chamber 301 can be fixed by high-temperature steam. The steam inside is discharged from the second guide tubes 304 on both sides. If the gap between the second guide tube 304 and the polyester filaments is too small to meet the steam discharge, the internal air pressure of the high-temperature steam chamber 301 will increase. At this time, the excess steam can be discharged through the vent pipe 306 and the vent valve 307. The condensate inside the high-temperature steam chamber 301 is discharged and collected through the drain pipe 308. The collected condensate can be used for subsequent cleaning.

[0038] In the above structure, the cleaning mechanism 4 includes a cleaning tank 401, an ultrasonic generator 402, a second guide roller 403, a second rotating shaft 404, and a second guide wheel 405.

The second rotating shaft 404 is rotatably connected inside the cleaning tank 401 below the second guide roller 403. Several second guide wheels 405 are fixedly connected to the second rotating shaft 404. The polyester yarn after high-temperature color fixing is introduced into the cleaning tank 401 from the second guide roller 403 on one side, and is introduced into clean water through the second guide wheel 405 inside the cleaning tank 401. At this time, the ultrasonic generator 402 is activated to deeply clean the polyester yarn with the generated high-frequency sound waves. Afterwards, it can be led out of the cleaning tank 401 by passing around the second guide roller 403 on the other side.

[0039] In the above structure, the drying mechanism 5 includes a drying chamber 501, a third guide roller 502, a third guide wheel 503, a warm air blower 504, and an exhaust pipe 505. Several third guide tubes 506 are fixedly connected to the outer walls of both sides of the drying chamber 501. A third guide roller 502 is fixedly connected to the drying chamber 501 on one side of each third guide tube 506. Several third rotating shafts 507 arranged in a staggered sequence are rotatably connected within the drying chamber 501 between the third guide rollers 502. A baffle plate 508 is fixedly connected within the drying chamber 501 between the third rotating shafts 507. Fixed... A number of third guide rollers 503 are connected. A heater 504 is fixedly connected to one side of the drying chamber 501, and an exhaust pipe 505 is fixedly connected to the top of the other side of the drying chamber 501. The washed polyester yarn is introduced into the drying chamber 501 from the third guide pipe 506 on one side.

During this process, the path is divided by the baffle plate 508 to extend the ventilation path and thus improve the drying effect. After drying, the polyester yarn passes around the third guide roller 502 on the other side and exits the drying chamber 501 from the third guide pipe 506 on one side.

[0040] In the above structure, the winding mechanism 6 includes a mounting block 601, a second rotating shaft frame 602, a second rotating shaft 603, a take-up spool 604, a transmission wheel 605, a drive wheel 606, and a drive motor 607.
