Abstract

The invention discloses an automatic presser foot lifting and backward and forward sewing device of a sewing machine. The automatic presser foot lifting and backward and forward sewing device comprises a presser foot lifting driver. A first straight rod of the presser foot lifting driver is connected with one end of a pull rope of a pull rope assembly, and the other end of the pull rope is connected with one end of a swing rod. The other end of the swing rod is in contact with one end of a presser foot lifting rear lever which can swing around the lever axis. A presser foot lifting mechanism is connected with the other end of the presser foot lifting rear lever and can be driven to act through swing of the presser foot lifting rear lever. The automatic presser foot lifting and backward and forward sewing device further comprises a backward and forward sewing driver. A second straight rod of the backward and forward sewing driver is connected with one end of a pull rod, and a swing plate seat is connected with the other end of the pull rod. Backward and forward sewing action can be achieved through swing of the swing plate seat. The automatic presser foot lifting and backward and forward sewing device is simple and compact in structure, convenient to install and maintain, low in manufacturing cost and capable of being in comprehensive application with a traditional presser foot lifting and backward and forward sewing mode. The invention further discloses the sewing machine with the automatic presser foot lifting and backward and forward sewing device.

Description

technical field [0001] The invention relates to a component of industrial sewing equipment, in particular to an automatic presser foot lifter and reverse sewing device of a sewing machine. The invention also relates to a sewing machine with automatic presser foot lifter and reverse sewing. Background technique [0002] Industrial sewing machines are becoming more and more automated, while traditional sewing machines require manual operation for lifting the presser foot and reverse sewing, which is not only cumbersome to operate, but also requires a certain level of operation of workers. This mode of operation leads to low production efficiency and high labor costs, which has become increasingly unable to meet people's needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic presser foot lifting and reverse sewing device for sewing machines, which can realize the functions of sewing machine lifting the...
