Kind Code:
A1
Abstract:
Disclosed is an adjustable moving blade thread-trimming mechanism of a short-thread-end roller-feed sewing machine. The mechanism comprises a kettle shaft middle sleeve (1), a kettle shaft (2), a moving-blade holder (3), a moving blade (4), a fixed blade (5), a rotating shuttle (6) and a machine needle (7), wherein the kettle shaft (2) is installed in the kettle shaft middle sleeve (1); the moving-blade holder (3) is installed on the kettle shaft middle sleeve (1); the moving blade (4) is installed on one side of the moving-blade holder (3); the fixed blade (5) is arranged on one side of the moving blade (4); the rotating shuttle (6) is installed above the kettle shaft (2); and the machine needle (7) is arranged above the rotating shuttle (6). The moving blade and the moving-blade holder of the thread-trimming mechanism are of a split structure, such that machining is convenient, the machining cost is low, the machining precision is easier to guarantee, and the position of the moving blade can be adjusted at will according to requirements, so that installation and adjusting are convenient, thus, the optimal thread hooking and trimming effects are achieved; and when the rotating shuttle is worn, the moving blade can be adjusted, and it is then possible to continue using the rotating shuttle, such that the service life cycle of the rotating shuttle is prolonged, and user costs are reduced.
