Abstract

A electronic elastic cord feeding device for a sewing machine relates to the sewing machine technical field; the end of a stepping motor is connected with an electric control box through an encoder; the front end of the stepping motor is fixed on one side of a fixed cover; the other end of the fixed cover is fixedly provided with a fixed mount; a roller base is arranged in the fixed mount; large and small rollers arranged side by side are arranged in the inner side of the roller base; the stepping motor is connected with the roller base through an universal joint arranged in the fixed cover; the other end of the small roller is connected with a release handle arranged outside the fixed mount; a clutch wrench is fixed on the roller base and connected with the large roller. The electronic elastic cord feeding device for the sewing machine can improve sewing quality, can reduce labor intensity of workers, thus improving cord feeding working efficiency and sewing speed; the desired tightness for the elastic cord can be ensured in long time cord feeding, so the tightness of clothes, fabric and finished product can be the same, and wrinkling is more uniform.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to an electronic elastic band feeding device for sewing machines. Background technique [0002] The tape feeding devices of existing sewing machines are all mechanical, but they have the defects of low tape feeding accuracy and large errors. The tape feeding will become looser or tighter for a long time, which will easily cause defective products. Contents of the invention [0003] The object of the present invention is to provide an electronic elastic belt feeding device for sewing machines, which fills the gap that there is no electronic elastic belt device on the market, improves the sewing quality, reduces the labor intensity of the staff, improves the work efficiency and sewing speed of the belt feeding, and can be used for a long time. It can always maintain the desired tightness of the elastic band when feeding the belt. [0004] In order to achieve the above objec...
