Sewing machine for stitching hot wire and method for preventing hot wire from twisting during use of sewing machine

Abstract

The invention relates to a sewing machine for stitching a hot wire and a method for preventing the hot wire from twisting during the use of sewing machine. The method can be used for preventing the hot wire from twisting when the hot wire is sewn to a sewn object, so as to avoid the phenomenon that the hot wire is broken due to bending. The sewing machine comprises a sewing machine head driving unit, an embroidery frame driving unit and a control unit, wherein the sewing machine head driving unit is used for driving a sewing machine head to move up and down; the embroidery frame driving unit is used for driving an embroidery frame to move transversely or longitudinally; and when the embroidery frame moves to sew the hot wire, the control unit is used for stopping the driving of the sewing machine head and the embroidery frame, driving the sewing machine to rise to a certain height, driving the embroidery frame to move in a set direction, and driving the sewing machine head to fall to sew the hot wire again. The invention has the advantage that the phenomenon that the hot wire is broken due to twisting is eliminated, so as to ensure stable quality.

Description

technical field [0001] The present invention relates to a sewing machine for sewing heating threads and a method for preventing twisting of heating threads using the sewing machine. When the heating thread is sewn on the product, it can prevent the heating thread from being twisted, so that when the heating thread is sewn to the sewing object, the situation of breaking the thread due to bending can be avoided. Background technique [0002] Recently, products such as car mats and warming mats, which are suitable for heat preservation or room heating after arranging heating threads on sewn objects, have been launched on the market. [0003] For example, Japanese Laid-Open Patent Publication JP3190080A describes a detection device for occlusal heating wires, and its publication date is August 20, 1991. In this detecting device for interlocking the heating wire, a switch is provided between a sewing needle that sews the heating wire supplied from the heating wire supply part t...
