Embodiment Construction

[0018] The invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1~3 As shown, a manual wire feeding mechanism for a keyhole machine includes a puller piece 1 and a rotating shaft 2, the puller piece 1 is provided with two puller holes 3, and the rotating shaft 2 is rotatably connected to the body 4, One end is fixedly connected to one side of the pull-wire sheet 1, and the other end is fixedly connected to the rocker handle 5. After passing the wire 14 through the first hole on the front side of the pull-wire sheet, it goes around the outer side of the pull-wire sheet 1 and passes through the front side of the second hole. Turning the rotating shaft can realize the forward pulling of the thread, so that after the keyhole is completed, a section of thread is reserved for easy cutting.

[0020] Preferably, the above-mentioned puller piece 1 is a bent L-shaped structure with a simple structure...

Abstract

The invention discloses a manual wire feeding mechanism for a buttonholing machine. The manual wire feeding mechanism comprises a wire drawing sheet and a rotating shaft. Two wire drawing holes are formed in the wire drawing sheet, the rotating shaft is rotationally connected on a machine body, one end of the rotating shaft is fixedly connected to one side of the wire drawing sheet, and a cranking handle is fixedly connected to the other end of the rotating shaft. According to the manual wire feeding mechanism, the cranking handle drives the rotating shaft, the rotating shaft drives the wire drawing sheet to rotate, a wire on the wire drawing sheet is sent frontwards by a section of the reserved length accordingly, buttonholing is conveniently shortened after being completed, and the inconvenient clipping technical problem caused by the insufficient reserved length in the prior art is effectively solved; the manual wire feeding mechanism also has the advantages that the structure is simple, operating, using, assembling, disassembling and maintaining are convenient, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and in particular relates to a manual thread feeding mechanism of a buttonhole machine. Background technique [0002] After the buttonhole is completed, the existing buttonhole machine needs to send the thread to the needle to reserve a certain length, and the connecting rod is driven by the motor to realize the thread feeding, but the existing buttonholing machine often leads to insufficient reserved length for thread feeding , It is inconvenient to use scissors to cut, and it is easy to cause the problem of disconnection, and it increases the complexity and energy consumption of the equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a buttonhole machine manual wire feeding mechanism with simple structure, convenient operation and use, convenient wire feeding and long enough reserved length in view of the problems exi...
