Problems solved by technology

[0004] In the actual sewing process, it is necessary to cut a long incision on the sewing material before sewing. Since the rotary punching machine can only punch a single hole, the punching speed cannot keep up with the moving speed of the sewing material and cannot meet the requirements. Operating requirements for cutting process

Abstract

The invention discloses a cutter driving mechanism of a sewing machine, which comprises a rotating sleeve arranged on a mounting plate, a cutter mounting seat is fixed on the inner wall of the sleeve, is installed in the cutter mounting seat and can rotate around its own axis and A cutter shaft that moves up and down along the axis, a cutter is fixed below the cutter shaft, and a cutting drive motor for driving the cutter shaft to move up and down is fixed on the mounting plate. The power output shaft of the material cutting drive motor is provided with an eccentric wheel, and the eccentric wheel is equipped with an eccentric wheel bearing. The upper end of the eccentric wheel connecting rod is fixedly connected with the eccentric wheel bearing, and the lower end is connected with the cutter shaft through the material cutting transmission mechanism.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a cutting knife driving mechanism of the sewing machine. Background technique [0002] The utility model patent with the patent number of 201620092308.8 discloses a rotary punching machine, which can enable the sewing machine to have the function of punching the sewing material during the working process, and the punching knife can automatically rotate to punch out different angles of punching on the sewing material. hole. This rotary punching machine is suitable for the process that needs to make holes in the sewing material and then sew. [0003] The rotary punching machine disclosed in the above-mentioned patent includes a sewing machine head, a rotatable driven wheel is installed on one side of the sewing machine head, and a motor that drives the driven wheel to rotate through a transmission mechanism. The shaft center of the driven wheel is formed with a splined connecting rod bushing, ...
