Description

Technical Field

[0001] The utility model relates to the technical field of buttonhole machines, in particular to a thread clamping device of a buttonhole machine. Background Art

[0002] The buttonhole machine is a very important equipment in clothing machinery. It is mainly used to process buttonholes in various types of clothing. It is divided into flat buttonhole machines and eyelet buttonhole machines, and is further divided into two types: finishing and non-finishing. The eyelet buttonhole machine system is generally composed of nine major mechanisms: feeding mechanism, hook mechanism, needle bar mechanism, stretching mechanism, hook and shuttle mechanism, knife feeding mechanism, slide mechanism, and thread dividing mechanism. Each set of mechanisms has its own characteristics and functions and is relatively independent, but they work closely together and coordinate with each other.

[0003] During the thread-releasing process of the buttonhole machine, the thread tensioning force needs to be increased by a thread clamping device. Usually, multiple rollers are installed inside the thread clamping device, and the thread contacts the rollers, so that the entire thread has tension. However, due to the effect of the tension, the entire thread will be subject to a large friction force between the rollers, which can easily cause the thread to break during this process. Therefore, the above problem needs to be improved. Utility Model Content
