Description

Technical Field

[0001] The utility model relates to a novel dyeing machine, belonging to the field of textiles. Background Art

[0002] Traditional denim yarn needs to be scoured and cleaned with water before dyeing; during dyeing, it needs to go through 5 to 10 dyeing tanks for dyeing; after dyeing, it needs to go through 2 to 3 water washes. The whole process is relatively complicated, with many steps and processes, and the color effect is relatively single, which cannot meet the needs of the market. With the change of lifestyle, consumers' pursuit of denim clothing has changed greatly. In addition to traditional indigo dyes and sulfur dyes, denim fabrics of various colors are also sought after by people.

[0003] Indigo dyes and sulfur dyes are dyed by dip-dyeing, while new dyes have more ways to dye.

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0026] Reference Figures 1 to 4The embodiment of the present application provides a new dyeing machine, including a dyeing chamber 7, a recovery tank 9 and a dye master tank 8. The dyeing chamber 7 is provided with a yarn guide roller for tightening the yarn bundle 5, a turntable 72 whose sputtering range covers the yarn bundle 5, a replenishing mechanism for adding dye liquid to the turntable 72, and a spraying mechanism higher than the turntable 72 and aimed at the inner wall of the dyeing chamber 7. The bottom of the dyeing chamber 7 is provided with a residual liquid collection part 74 discharged to the recovery tank 9. The dye master tank 8 is used to add dye to the secondary dye liquid. The new dyeing machine is also provided with a return pipe 6 for pumping the secondary dye liquid back to the replenishing mechanism. It should be noted that Figure 1 , Figure 2 and Figure 4 Only to clearly show the internal structure of the dyeing chamber 7, the size ratio of each component may not be the same as that of the actual machine. For example, compared with the attached figure, in the actual machine, the yarn bundle 5 is thinner and denser. For another example, the attached figure is a shortened version, and the actual machine is more than ten meters long, and more than ten or twenty turntables 72 are lined up on the same horizontal plane of the dyeing chamber 7.

[0027] The characteristic of splash dyeing is that the yarn bundle 5 is dyed randomly. Therefore, in the embodiment of the present application, the splashed dye still will not all hit the yarn bundle 5, and the excess dye will also hit the inner wall of the dyeing bin 7. However, the present application is provided with a spray mechanism, which can continuously rinse the inner wall of the dyeing bin 7, keep the inner wall of the dyeing bin 7 moist, and have continuously flowing water to prevent the dye from adhering to the inner wall of the dyeing bin 7. The spray water and excess dye naturally flow to the residual liquid collection part 74. The excess dye consists of two parts, one is the part that hits the inner wall of the dyeing bin 7, which is washed down by the spray water, and the other is the part that neither hits the yarn nor the inner wall of the dyeing bin 7, which falls directly into the residual liquid collection part 74. The residual liquid collection part 74 is discharged to the recovery tank 9. At this time, the dye is equivalent to being diluted, and dye needs to be added with the help of the dye master tank 8. Specifically, refer to Figure 1 A water inlet interface 763 connected to the spray mechanism in the dyeing chamber 7 is provided on the side of the dyeing chamber 7 for connecting tap water.

[0028] Reference Figure 4 The spray mechanism includes a water supply pipe 76 and a duckbill nozzle 761 arrayed on the water supply pipe 76, and the duckbill nozzle 761 is aimed at the inner wall of the dyeing chamber 7. The duckbill nozzle 761 can form a water curtain with a lower water flow rate, which is conducive to washing the inner wall of the dyeing chamber 7 with less water and reducing the dilution of excess dye.

[0029] In some embodiments, an adjustment tank (not shown) can be added so that the flow rate of the secondary dye solution in the recovery tank 9 can be discharged to the adjustment tank in a controllable manner. The dye master tank 8 adds dye to the adjustment tank, and the concentration of the secondary dye is controlled in the adjustment tank. One end of the recovery pipeline 6 is connected to the adjustment tank, and the other end is connected to the replenishment mechanism.

[0030] exist Figure 3In the embodiment shown, the concentration of the secondary dye solution is adjusted directly in the recovery tank 9. The dye master tank 8 directly adds dye to the recovery tank 9, and the input end of the back-drawing pipeline 6 is connected to the recovery tank 9, and the output end is connected to the replenishment mechanism.

[0031] In actual production, the speed of the yarn bundle 5 is constant, and the amount of dye liquid carried away by the yarn bundle 5 is stable, that is, the amount of dye and solvent water carried away by the yarn bundle 5 is stable. Therefore, as long as the spray power and the feed amount of the dye master tank 8 are set consistent with the consumption, the concentration of the secondary dye liquid and the liquid level of the recovery tank 9 can be kept stable.

[0032] Reference Figure 3 In the optimized embodiment, tap water enters through the water inlet pipe 764, is divided into two, and enters the two water supply pipes 76 in parallel. The new dyeing machine also includes a controller 3, a spray mechanism is connected to a water inlet valve 762, a lift pump 61 is connected in series in the middle of the back-drawing pipeline 6, the input end of the back-drawing pipeline 6 is connected to the recovery tank 9, the dye mother tank 8 is connected to the recovery tank 9 through the feeding valve 81, and a dye concentration sensor 4 is arranged in the recovery tank 9. The controller 3 is electrically connected to the dye concentration sensor 4, the water inlet valve 762, the feeding valve 81, and the lift pump 61. The dye concentration in the recovery tank 9 is monitored in real time by the dye concentration sensor 4 and fed back to the controller 3. The controller 3 adjusts the amount of water used for spraying, the amount of dye added, and the power of the lift pump 61 accordingly. It should be noted that Figure 3 The dashed lines in the diagram represent electrical or signal connections.

[0033] Preferably, a liquid level meter is also provided in the recovery tank 9. The controller 3 adjusts the spray water consumption, dye dosage and the power of the booster pump 61 in real time according to the data of the dye concentration sensor 4 and the liquid level meter, and can also maintain the stability of the secondary dye concentration and the liquid level of the recovery tank 9.

[0034] More preferably, the controller 3 also controls the rotation speed of the yarn guide roller, so as to keep the liquid level of the recovery tank 9 and the concentration of the secondary dye solution stable in combination with the traveling speed of the yarn bundle 5, the amount of water used for spraying, the amount of dye added and the power of the booster pump 61.

[0035] In the existing splash dyeing technology, the turntable 72 is usually immersed in the dye liquid, the initial velocity of the dye liquid is low, the distance of the throw is short, and the turntable needs a large rotation speed to work. In the embodiment of the present application, the supplementary mechanism includes a dye liquid spray pipe 75 aimed at the top surface of the turntable 72, and the dye liquid spray pipe 75 is higher than the turntable 72 and lower than the spray mechanism. The dye liquid comes out of the dye liquid spray pipe 75 and is ejected to the top surface of the turntable by gravity and water pressure, which can splash farther, which is conducive to the turntable 72 working at a lower rotation speed. Specifically, a turntable base 721 is horizontally placed in the dyeing chamber 7, and the rotating shaft of the turntable 72 penetrates into the interior of the turntable base 721. The rotating shaft is connected to a pulley in the turntable base 721, and the pulleys of multiple turntables 72 are uniformly driven by a belt, and the belt drive is connected to a motor (not shown) outside the dyeing chamber 7.

[0036] More preferably, the top surface of the turntable 72 is a downwardly concave arc surface, so that when the dye liquid is ejected from top to bottom to the downwardly concave top surface of the turntable, it can splash farther.

[0037] Specifically, the dye liquid spray pipes 75 correspond to the turntable 72 one by one, and a plurality of dye liquid spray pipes 75 are connected in parallel to a dye liquid supply pipe 751 , and the dye liquid supply pipe 751 is connected to the re-suction pipeline 6 .

[0038] Reference Figures 2 to 4 The yarn guide rollers include a first yarn guide roller 771 for guiding the yarn bundle 5 to enter the dyeing chamber 7 from the top of the dyeing chamber 7, and a second yarn guide roller 772 for guiding the yarn bundle 5 to turn and leave the dyeing chamber 7 obliquely upward from one side of the dyeing chamber 7. The yarn bundle 5 leaves the dyeing chamber 7 obliquely upward, which is conducive to allowing the dye liquid that has not completely penetrated into the yarn to flow down along the yarn bundle 5 under the action of gravity, thereby improving the penetration rate of the yarn and recovering excess dye liquid.

[0039] Specifically, the yarn bundle 5 between the first yarn guide roller 771 and the second yarn guide roller 772 is vertical, and the turntable 72 rotates horizontally. The turntable 72 is lower than the first yarn guide roller 771 and higher than the second yarn guide roller 772.

[0040] Reference Figure 3 and Figure 4 It can be seen that in order to make the yarn bundle 5 tilt upward when leaving the dyeing chamber 7, a second yarn guide roller 772 needs to be located under an inner wall of the dyeing chamber 7, and the inner wall has a water curtain for washing, which can easily wash away the dye just dyed. Figure 2 A water retaining groove 71 is provided at the bottom end of the side wall, and the water retaining groove 71 spans the entire length of the second yarn guide roller 772. Both ends of the water retaining groove 71 are provided with guide parts 711 that discharge to the residual liquid converging part 74 to prevent the water curtain from splashing onto the yarn guide roller or yarn.

[0041] Reference Figure 4 The residual liquid converging portion 74 includes a guide plate 741 and a filter plate 742. The guide plate 741 is inclined inward from top to bottom, and the filter plate 742 is arranged at the lower end of the guide plate 741. The filter plate 742 is used to filter the yarn hairiness to prevent the yarn hairiness from clogging the replenishing mechanism.
