Sewing machine and fabric flattening device

Abstract

The invention discloses a fabric flattening device. The fabric flattening device includes a rotation shaft, a fabric filtering plate mounted on a sewing station and a rotation shaft mounting seat, wherein a rotation shaft extends transversely through a shaft hole on the rotation shaft mounting seat and is rotatably connected with the rotation shaft mounting seat, the rotation shaft is sleeved witha torsion spring, one end of the torsion spring is fixed on the rotation shaft, the other end is fixed with the rotation shaft mounting seat, one end of the rotation shaft near the fabric filtering plate is equipped with a pressing plate matched with the fabric filtering plate to spread the material, under the torsion force of the torsion spring, the pressing plate fixed on the rotation shaft presses against the fabric filtering plate and is adhered to the fabric filtering plate to form a narrow sewing edge, when the fabric is sown, the rotation shaft is made to rotate to lift the pressing plate to dispose the fabric on the fabric filtering plate, the rotation shaft is loosened so that the fabric is sandwiched between the pressing plate and the fabric filtering plate, when the fabric moves through the narrow sewing edge in the feeding direction, the rolled fabric is flattened by the narrow sewing edge, a turner is facilitated to perform fast and accurate sewing, and sewing efficiencyand the yield are improved. The invention further discloses a sewing machine equipped with the fabric flattening device.

Description

technical field [0001] The invention relates to the technical field of fabric sewing tools, in particular to a fabric flattening device. In addition, the present invention also relates to a sewing machine comprising the above fabric flattening device. Background technique [0002] Sewing is a technique of interweaving or stitching one or more layers of fabrics, and a sewing machine is a tool for fast sewing of fabrics. [0003] At present, the edge of the fabric is easily rolled up during the sewing process, which makes it impossible to sew quickly and accurately, resulting in a large reject rate. In addition, it is difficult for the lathe workers to sew the rolled fabric, resulting in low work efficiency. [0004] Therefore how to solve the problems such as low sewing efficiency and low yield due to fabric roll-up in the sewing process is a technical problem that those skilled in the art need to solve at present. Contents of the invention [0005] The object of the pres...

Problems solved by technology

[0003] At present, the edge of the fabric is easy to roll up during the sewing process, which will cause the inability to sew quickly and accurately, resulting in a large waste rate. In addition, it is difficult for the lathe workers to sew the roll-up fabric, resulting in low work efficiency.

[0004] Therefore how to solve the problems such as low sewing efficiency and low yield rate caused by fabric rolling up in the sewing process is a technical problem that those skilled in the art need to solve at present
