Description

Technical Field

[0001] This application relates to the technical field of textiles, and in particular to a steam box sealing device. Background Art

[0002] In the textile process flow, sometimes it is necessary to send textile fabrics into a steam box for high-temperature steam treatment to improve the finished product quality of the textile fabrics. A transmission shaft is arranged in the steam box, and a sealing ring is arranged on the transmission shaft. The sealing ring can seal the gap between the transmission shaft and the steam box.
