[0002] In the field of polyester high -strength silk dyeing, traditional dyeing equipment has many problems. The traditional dyeing equipment usually adopts the way of a large number of dyes soaking to dye polyester high -strength silk, and this way not only wastes dyes, increases dyeing cost, but also easily causes environmental pollution.

[0003] In the dyeing process of traditional equipment, the temperature of dyes is difficult to keep constant, which will affect the quality of dyeing. Unstable temperature can lead to uneven dyeing, dull color, and even dyeing defects.

[0004] In addition, the dyeing efficiency of traditional equipment for polyester high -strength silk is low. The speed of dye penetration into the high -strength silk is slow, and it is difficult to achieve rapid and uniform dyeing. Moreover, the traditional equipment generally does not have the function of dyeing and drying integration, and after dyeing, the polyester high -strength silk needs to be transferred to other equipment for drying, which increases the production process and time cost.

[0018] 2. Innovative heating and distribution system: The upper end of the heating cylinder is connected to the distribution plate and the distribution tube. The distribution tube is connected to the guide tube by rotation. The heated dye is introduced into the guide tube through the distribution plate and the distribution tube. Then, the dye is sprayed into the space between the yarn bobbin and the guide tube and into the interior of the high-strength polyester yarn through the dyeing nozzles on the guide tube. This allows the dye to penetrate quickly and combine evenly, improving dyeing efficiency and quality.

[0019] 3. Dye-saving innovation: The dye is directly sprayed into the inside of the yarn bobbin to dye the high-strength polyester yarn, eliminating the need for large amounts of dye soaking, thus saving dye, reducing dyeing costs and environmental pollution.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-4 The dyeing equipment for colored high-strength polyester yarn shown includes a dyeing tank 1, with a top cover 2 at the upper end of the dyeing tank 1. Multiple yarn bobbins 3 are arranged inside the upper end of the dyeing tank 1, and each yarn bobbin 3 is wound with high-strength polyester yarn. Multiple support legs 4 are fixedly connected to the outer side of the lower end of the dyeing tank 1. A dye tank 5 is arranged on the right side of the dyeing tank 1. A circulation pump 6 is connected to the lower left side of the dye tank 5. A heating cylinder 7 is connected to the left end of the circulation pump 6, and the upper end of the heating cylinder 7 is connected to the interior of the lower center of the dyeing tank 1. A return pipe 8 is connected to the right side of the lower center of the dyeing tank 1, and the return... The right end of tube 8 is connected to the center of the left end of dye barrel 5. Polyester high-strength yarn is wound around the outside of yarn bobbin 3 and put into dyeing barrel 1 for dyeing. Dye is prepared inside dye barrel 5 and introduced into heating cylinder 7 through circulation pump 6 for heating. The heated dye is introduced into dyeing barrel 1 and dyes the polyester high-strength yarn inside dyeing barrel 1. The dye inside dyeing barrel 1 can be guided back into dye barrel 5 through return pipe 8 for circulation heating, ensuring that the temperature of dye inside dyeing barrel 1 remains constant, thereby improving dyeing quality.

[0030] Preferably, a distribution plate 11 is connected to the upper end of the heating cylinder 7, and the distribution plate 11 is located inside the lower end of the dyeing barrel 1. Multiple distribution pipes 12 are connected to the upper end of the distribution plate 11. A guide pipe 13 is rotatably connected inside the distribution pipe 12. A limit ring 14 is fixedly connected to the lower end of the guide pipe 13, and the limit ring 14 is located inside the distribution plate 11 and fits against the inner wall of the upper end of the distribution plate 11. A limit seat 15 is fixedly connected to the middle of the outer side of the cylindrical guide pipe 13, and the limit seat 15 is located at the upper end of the distribution pipe 12 and fits against the outer wall of the upper end of the distribution pipe 12. The yarn spool 3 is sleeved on the upper side of the guide pipe 13 and is located above the limit seat 15. Multiple dyeing nozzles 18 are opened inside the upper side of the guide pipe 13, and the multiple dyeing nozzles 18 are all located at... On the upper side of the limiting seat 15, the dye heated by the heating cylinder 7 is introduced into the distribution plate 11, and then introduced into the interior of multiple guide pipes 13 through multiple distribution pipes 12. The multiple guide pipes 13 spray the dye into the space between the yarn bobbin 3 and the guide pipes 13 through multiple dyeing nozzles 18, and spray the dye into the interior of the polyester high-strength yarn wound around it through multiple dyeing nozzles 18 inside the yarn bobbin 3. The high-temperature dye is sprayed into the interior of the polyester high-strength yarn under high pressure from the inside out, which not only allows the dye to penetrate into the interior of the polyester high-strength yarn quickly, but also causes a certain degree of expansion, allowing the dye to diffuse into the interior of the polyester high-strength yarn more easily. This allows the polyester high-strength yarn to combine with the dye quickly and evenly, thereby improving the dyeing efficiency and dyeing quality of the polyester high-strength yarn.

[0031] Preferably, since the dye can be directly sprayed into the inside of the yarn tube 3 to dye the high-strength polyester yarn, there is no need for soaking in a large amount of dye, which can save more dye, reduce dyeing costs, and reduce environmental pollution.

[0032] Preferably, a fixing nut 19 is threaded onto the upper end of the guide tube 13, and the fixing nut 19 is located at the upper end of the yarn spool 3. Positioning rings 20 are provided inside both the upper and lower ends of the yarn spool 3, and the yarn spool 3 is sleeved on the upper outside of the guide tube 13 through two positioning rings 20. The yarn spool 3, which is wound with high-strength polyester yarn, can be fixed to the upper outside of the guide tube 13 through the limiting seat 15 and the fixing nut 19, and can be positioned with the guide tube 13 through the positioning rings 20 at both ends, so that the yarn spool 3 can be stably fixed outside the guide tube 13, and a gap is left between it and the guide tube 13, so that the dye can be evenly introduced into the multiple dyeing nozzles 18 inside the yarn spool 3 through the gap, ensuring uniform dyeing.

[0033] Preferably, multiple balls 16 are rolledly connected to the inner upper end of the limiting ring 14 and the inner lower end of the limiting seat 15. The limiting ring 14 and the limiting seat 15 are rotatably connected to the inner upper end of the distribution plate 11 and the outer upper end of the distribution pipe 12 respectively through the multiple balls 16. A spiral plate 17 is fixedly connected to the inner lower side of the guide pipe 13. When the dye flows through the inside of the guide pipe 13, the dye can drive the guide pipe 13 to rotate inside the distribution pipe 12 through the spiral plate 17. This causes the dye between the yarn bobbin 3 and the guide pipe 13, as well as the yarn bobbin 3, to rotate. The dye between the yarn bobbin 3 and the guide pipe 13 will be thrown outward under the action of centrifugal force, so that the dye can enter the interior of the high-strength polyester yarn under high pressure and under the action of centrifugal force, thereby improving the efficiency of dye penetration into the interior of the high-strength polyester yarn and the diffusion efficiency, and thus improving the dyeing efficiency.

[0034] Preferably, the left end of the heating cylinder 7 is connected to an air suction pump 9, and a filter element is installed inside the opening at the left end of the air suction pump 9. Valves 10 are installed between the heating cylinder 7, the circulation pump 6, and the air suction pump 9. After dyeing, the valve 10 on the right side is closed, and the valve 10 on the left side is opened. At the same time, the air suction pump 9 is turned on and the circulation pump 6 is turned off. The air suction pump 9 draws air into the cylinder through the opening on the left side and filters the air through the filter element. The filtered air is then introduced into the heating cylinder 7 and finally introduced into the yarn bobbin 3 through the distribution plate 11, the distribution pipe 12, and the guide pipe 13. At this time, the air inside the guide pipe 13 drives the yarn bobbin 3 and the guide pipe 13 to rotate through the spiral plate 17. Heated gas is introduced into the polyester high-strength yarn through multiple dyeing nozzles 18, allowing the dye inside the polyester high-strength yarn to be quickly ejected under centrifugal force. At the same time, the internal moisture is quickly removed under the baking of high-temperature gas. This allows the dyeing tank 1 to quickly dye and dry the polyester high-strength yarn. The gas introduced into the dyeing tank 1 can also quickly press the dye ejected into the dyeing tank 5 through the return pipe 8. At the same time, the gas introduced into the dyeing tank 1 can also enter the dyeing tank 5 through the return pipe 8, and the dye in the dyeing tank 5 absorbs and filters the dye droplets in the gas, reducing environmental pollution.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
