Description

Technical Field

[0001] The invention relates to the technical field of dyeing machines, in particular to a half-width air overflow dyeing machine. Background Art

[0002] With the increasing national environmental protection requirements and the continuous increase in energy prices, enterprises have put forward higher requirements for traditional dyeing equipment. Saving water, electricity and dyes are the main features of this dyeing machine.

[0003] Airflow dyeing machines rely on airflow to operate, while overflow dyeing machines rely on water flow nozzles to operate. In the market, both airflow and overflow operate in a rope-like manner. Airflow dyeing machines are designed as O-type machines due to their slow flow rate. Overflow machines are designed as L-type machines due to their high flow rate. O-type machines have a small bath ratio, but are only suitable for cotton interwoven fabrics. Because the cylinder body is O-shaped, the fabrics in the cylinder body are prone to defects such as chicken claw marks and wrinkles due to accumulation and extrusion. It is not suitable for sensitive fabrics with high color requirements, and O-type machines cannot deliver fabrics over long distances. L-type machines have loose fabric accumulation, fewer defects such as chicken claw marks and wrinkles, and full colors, but they use a large amount of water and can easily cause fabric scratches due to rapid movement. Summary of the invention

[0004] The invention mainly solves the problems in the prior art that the dyeing machine runs in a rope-like manner, dyes unevenly, and cannot deliver cloth over a long distance, and provides a half-width air overflow dyeing machine.
