Description

Technical Field

[0001] This utility model relates to the field of sewing thread oiling, and in particular to a sewing thread oiling device. Background Technology

[0002] In the field of textile machinery, the oiling of sewing thread is a key step in ensuring sewing quality. Existing sewing thread oiling devices typically have the following technical problems: the thread inlet structure of the oiling component is mostly a fixed design, which makes the thread threading process cumbersome and requires the disassembly of a large number of parts to complete the threading operation, which seriously affects production efficiency. The lubricating oil circulation system of traditional oiling devices lacks an efficient filtration mechanism, and impurities such as fiber debris and dust carried by the sewing thread can easily mix into the lubricating oil, causing oil contamination. This not only makes the oiling effect uneven but also accelerates equipment wear.
