Description

Technical Field

[0001] The utility model relates to the technical field of coloring mechanisms, in particular to a coloring mechanism for solution-dyed nylon. Background Art

[0002] Solution coloring is to add appropriate colorants into the spinning solution, which is fully mixed, dissolved and filtered. The colorant or colored solution can also be quantitatively injected before entering the spinneret, and then spun into colored fibers after mixing in a static mixer. Coloring and spinning can be carried out simultaneously and continuously, with uniform coloring, good color fastness, high dyeing rate, short production cycle, low cost and less pollution. It is very common in the coloring of nylon, polyester, polypropylene and other fibers.

[0003] The existing liquid dyeing equipment quantitatively injects colorant for coloring before entering the spinneret. After coloring, it is impossible to timely and accurately judge whether the coloring effect meets the coloring requirements, so that the coloring mechanism cannot timely judge whether the coloring is uniform when performing coloring mixing. When the static mixer mixes the colorant with the spinning solution, the colorant adheres to the inner wall of the mixing tube and cannot continue to reach the static mixer for mixing in time, which is easy to affect the color accuracy of the coloring mechanism after coloring. Based on this, the utility model designs a coloring mechanism for liquid-dyed nylon to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a coloring mechanism for solution-dyed nylon to solve the problems in the prior art that the coloring uniformity of the existing solution-dyed nylon coloring mechanism is inconvenient to observe during use and the color accuracy after coloring is not stable enough.

A connecting pipe is fixed through the bottom of the transparent observation tube, and a check valve three is arranged on the connecting pipe.

[0007] Preferably, the output end of the motor rotates and penetrates into the mixing tube, and a stirring rod is fixed to one end of the motor output end extending into the mixing tube, and an auxiliary scraper is fixedly sleeved on the outer side of the stirring rod.

One end of the water pipe away from the mixing tube is externally connected to a clean water tank.

[0009] Preferably, the stirring rod is composed of a rotating rod and a plurality of stirring support rods equidistantly fixed on its outer surface, and a transparent observation window is provided on the front side of the mixing tube.

[0010] Preferably, the auxiliary scraper is arranged in a transversely placed "U" shape, and the outer surface of the auxiliary scraper is arranged in an arc shape that matches the inner wall of the mixing tube and is slidably fitted with the inner wall of the mixing tube.

[0011] Preferably, the connecting tube is fixedly connected to the liquid inlet end of the spinneret, a fixed slot is provided on the inner side of the upper part of the positioning sleeve, and the height of the fixed slot is smaller than the height of the color card, and the height of the color card is smaller than the height from the top surface of the positioning sleeve to the top surface of the transparent observation tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model can fix the color card through the color card comparison structure under the action of the support limit sleeve, so as to facilitate timely and all-round comparison of the spinning solution after coloring. In conjunction with the stirring rod, the mixing effect of the solution is fully improved, and it is convenient to observe the coloring uniformity in time and make adjustments in time, so as to avoid the coloring spinning solution with uneven coloring from entering the spinneret, thereby solving the problem that it is inconvenient to observe the coloring uniformity when using the existing coloring mechanism of the solution-dyed nylon, and improving the coloring effect of the coloring mechanism.

[0014] (2) The auxiliary scraper can be used to prevent the colorant from remaining on the inner wall of the mixing tube when the spinning solution and the colorant are mixed, and the stirring rod can assist in mixing the spinning solution and the colorant, thereby ensuring the color accuracy of the coloring mechanism after coloring. This solves the problem that the coloring mechanism of the existing solution-dyed nylon has colorant remaining on the inner wall during use, affecting the color accuracy after coloring, and further improves the coloring effect of the coloring mechanism.
