Yarn dyeing machine

Abstract

The invention relates to a yarn dyeing machine, which comprises a dyeing box, jet pipes, a circulating pump and spray pipes, wherein a plurality of horizontal jet pipes are arranged in the dyeing box, and can be driven to rotate through a motor; the liquid outlet of the circulating pump is communicated with the jet pipes through a liquid supply pipe; the liquid inlet of the circulating pump is communicated with the bottom of the dyeing box through a reflow pipe; the spray pipes are arranged correspondingly to the jet pipes, and are communicated with the liquid outlet of the circulating pump through another liquid supply pipe; and a liquid supply three-way reversing valve is arranged between the two liquid supply pipes and the liquid outlet of the circulating pump. During dyeing, the circulating pump is used for supplying liquid to the jet pipes, and a dye solution is sprayed onto the inner side faces of yarns through the jet pipes for realizing dyeing. During yarn overturning, the circulating pump is used for supplying liquid to the spray pipes, and the dye solution is sprayed down from above the jet pipes for dyeing the yarns on the jet pipes. The spray pipes and the jet pipes are used for spraying onto the outer sides and the inner sides of the yarns respectively, so that dyeing is uniform, and dyeing efficiency is increased.

Description

Technical field [0001] The invention relates to a yarn dyeing machine, in particular to a yarn dyeing machine with high dyeing efficiency. Background technique [0002] The dyeing machine is an ideal bleaching and dyeing equipment suitable for a wide range of finished products. When the yarn dyeing machine is bleaching and dyeing, the yarn is hung on the horizontally arranged spray tube. Under the action of the circulating pump, the dye solution is sprayed onto the yarn through the spray tube to achieve dyeing. During the bleaching process, the yarn is sprayed at intervals The tube will rotate to overturn the hanging yarn on the jet tube, so as to achieve the goal of even dyeing. Since the dye liquor is located inside the yarn when it is sprayed from the jet pipe, in order to avoid the yarn from being scattered when the yarn is turned over, the circulating pump stops spraying the jet pipe and the dye liquor passes through the bypass pipe and the dyeing box. Conduction, anti-sed...

AI Technical Summary

Problems solved by technology

Since the dye liquid is located inside the yarn when it is sprayed from the injection pipe, in order to avoid the yarn from being scattered when the yarn is turned over, the circulation pump stops supplying liquid to the injection pipe and sprays the dye liquid through the bypass pipe and the dyeing box. Conduction, anti-sedimentation circulation of the dye solution, low dyeing efficiency
