Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a winding tensioning force adjusting device of a shuttle line changing platform. Background Art

[0002] The shuttle is a thread-supplying component of existing textile equipment. Its function is to supply thread to the textile machine for automated knitting processing. Usually, a textile machine will store multiple thread-supplying shuttles. When a shuttle with insufficient new thread is replaced, it faces the process problems of opening the shuttle cover, removing the new thread, inserting a new thread wheel, and rewinding the thread and positioning it on the shuttle cover.

[0003] The structure of an existing shuttle includes a bobbin case, a shuttle cover, and a thread pressing plate. The bobbin case is a hollow, spindle-shaped structure with an opening on one side and a cavity inside for placing a thread wheel. The shuttle cover is hinged to block the side wall of the bobbin case opening and is elastically fixed. The shuttle cover has a pre-tightening adjustment hinged thread pressing spring. After inserting a new bobbin into the shuttle and finding the thread end, the thread end of the new bobbin should be wound into the thread groove of the shuttle cover, then passed through the thread threading hole in the side wall of the bobbin case. Finally, the shuttle cover is tightened, and the knob on the thread pressing spring is manually adjusted to adjust the thread tension after the thread end extends through the thread threading hole. However, the above process is currently performed manually, and manual winding, threading, and cover fastening limit production efficiency and waste labor.

[0004] In summary, how to design a winding tension adjustment device for the shuttle line changing platform to realize the sixth process of automatic shuttle line changing, that is, to automatically adjust the tension of the shuttle line after the fifth process of winding and covering is completed, has become a technical problem that needs to be urgently solved by people in this field.
