[0002] In recent years, due to the rapid development of the country, people's demand for storage objects has increased day by day. Due to the large labor base in China, there are more and more textile factories in China. The circular knitting machine will produce a lot of noise due to its own vibration during operation, and will produce a lot of cotton dust and flying catkins. In addition, most of the textile factories in China are large factories and are equipped in batches.

[0003] When multiple machines are operating at the same time, the noise and flying catkins generated are far beyond the national standards. Working in this environment for a long time is extremely harmful to the physical and mental health of workers, and they may suffer from occupational diseases such as hearing loss and pneumoconiosis. In order to solve this situation and provide workers with a good and healthy working environment, we have proposed a noise reduction device for large circular knitting machines.
