Sewing machine and edge aligning device thereof

Abstract

The invention discloses an edge aligning device for aligning edges of upper and lower fabrics. The edge aligning device includes a manipulator; the manipulator includes a manipulator casing; a lower mechanical arm for controlling a lower fabric to move to a predetermined position and an upper mechanical arm for controlling an upper fabric to move to a predetermined position located at one side areconnected to the interior of the manipulator casing; a lower manipulator electromagnetic component for controlling the lower mechanical arm to rotate and an upper manipulator electromagnetic component for controlling the upper mechanical arm to rotate located on the other side are arranged in the manipulator casing. The invention also discloses a sewing machine including the edge aligning device.The edge aligning device can effectively utilize the space, simplify the overall structure, and achieve an efficient fabric edge aligning effect.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to an edge alignment device. The invention also relates to a sewing machine provided with the alignment device. 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 materials. The sewing machine is generally composed of a feeding device, a machine base, a transmission It is made up of four parts with the attachment, and through the reasonable cooperation of the movement of each mechanism, the circular work is used to sew the sewing materials together. [0003] At present, when the sewing machines on the market sew double-layer fabrics, since the edges of the upper and lower layers of fabrics have inconsistent shapes, the edges of the upper and lower layers of fabrics need to be aligned during the sewing process. The existing edge...

AI Technical Summary

Problems solved by technology

Generally speaking, the transmission parts of the above-mentioned edge-to-edge device are too complicated, resulting in low transmission efficiency of the sewing machine, which makes the manufacturing cost of the sewing machine relatively high and the reliability is relatively low. The large space below the board is not conducive to the spatial layout of automatic bobbin changers and other devices

[0004] Therefore, how to avoid the complex structure, low reliability and high manufacturing cost of the sewing machine due to the unreasonable layout of the sewing machine's edge-to-edge device is a technical problem that those skilled in the art need to solve at present.
