Shuttle assembly of sewing machine

Abstract

The invention relates to the technical field of sewing machines, and discloses a shuttle assembly of a sewing machine. The shuttle assembly comprises a shuttle sleeve and a rotary shuttle, a positioning block is arranged on the side of the shuttle sleeve, a positioning groove matched with the positioning block is arranged in an inner shuttle rack, a first connector is arranged at the bottom of aninner cavity, a second connector is arranged at the bottom of the shuttle sleeve, and the shuttle sleeve is detachably connected through the first connector and the second connector. Based on the above, during mounting the shuttle sleeve and the inner shuttle rack of the rotary shuttle are positioned through one positioning block, the shuttle sleeve is placed in the inner shuttle rack and is fixedly connected just through the first connector inside the inner cavity and the second connector at the bottom of the shuttle sleeve; the first connector and the second connector are arranged inside theinner cavity and at the bottom of the shuttle sleeve, so that the size of the shuttle sleeve and of the inner shuttle rack can be avoided being increased, and the integrity of the shuttle assembly isguaranteed; adjusting one positioning structure is just required for mounting and demounting; operating is simple, using is facilitated, time and labor are saved, and sewing efficiency of the sewingmachine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine shuttle assembly. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The shuttle assembly of the sewing machine is an important part of the sewing machine. It is used to place the bottom thread to ensure a smooth and reliable supply of the bottom thread. In the sewing machine, the shuttle assembly and the needle play a vital role in forming the stitches. [0003] The shuttle assembly is arranged under the needle plate of the sewing machine, and it includes a rotary hook and a hook cover arranged in the rotary hook. The shuttle cover is used to place the bobbin thread ball, and guide the bobbin thread of the thread ball to come out from the machine shuttle assembly and meet the surface of the machine...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the inner shuttle frame of the existing rotary hook and the shuttle cover are connected and fixed by multiple positioning and locking mechanisms, the structure is complex, the operation is inconvenient, and it is time-consuming and laborious, which is not conducive to improving the sewing efficiency of the sewing machine. efficiency
