Abstract

The invention relates to a unison feed device of an industrial horizontal-cylinder unison-feed sewing machine. The unison feed device comprises a shell, a belt pulley connected with a power mechanism, a transmission mechanism, a feed rocking bar group and a needle pitch adjusting device. The feed device realizes feed transmission through a feed eccentric cam. The feed eccentric cam is installed on an upper shaft which is driven by the belt pulley and is connected with a fork-shaped connecting bar in a driving way through a drive connecting bar. The tail end of the fork-shaped connecting bar is connected with a needle bar rocking connecting bar through a feed connecting pin and a rocking crank. The upper end of the needle bar rocking connecting bar is connected to the needle bar rocking background crank of the feed rocking bar group. A horizontal feed shaft is installed on a rocking curved bar. The needle pitch adjusting device comprises a needle pitch adjusting seat. A needle pitch adjusting handle and a differential adjusting shaft are installed on the needle pitch adjusting seat. The needle pitch adjusting seat is connected to the fork head of the fork-shaped connecting bar through a feed adjusting sleeve, a sliding sleeve seat and a sliding sleeve shaft. The unison feed device of the industrial horizontal-cylinder unison-feed sewing machine has the advantages that the feed accuracy is improved and the sewing machine can be enabled to satisfy higher processing requirements.

Description

technical field [0001] The invention relates to an industrial horizontal cylinder type comprehensive feeding sewing machine, in particular to an industrial horizontal cylinder type comprehensive feeding sewing machine comprehensive feeding device. Background technique [0002] Horizontal cylinder combined feeding sewing machine is one of the most widely used industrial sewing machines at present. It has powerful functions, strong adaptability, stable operation, and can sew a variety of materials, regardless of whether the surface of the material is smooth, rough, uneven or more. Layer sewing, stable operation, and the structure of the horizontal cylinder sewing machine is precise, so it is suitable for sewing shoes, leather bags, handbags, belts, edges and leather bags, and can also be used for sofa manufacturing and sports equipment. Cylindrical forming and more. [0003] The current horizontal cylinder sewing machines mostly use integrated feeding devices to automatically...
