Abstract

The invention provides a driving mechanism for thread sewing and presser foot lifting thread-scissoring and a buttonholing machine. The driving mechanism for the thread sewing and the presser foot lifting thread-scissoring comprises a driving motor, a first starting plate, a first transmission piece, a second reset spring, a second transmission piece and a first reset spring, wherein the first starting plate is in transmission connection with the driving motor; the first transmission piece drives a thread sewing component to move; the second reset spring is used for resetting the first transmission piece; the first transmission piece is connected with a thread-loosening connecting rod in a thread sewing component; one end of the first transmission piece is connected with the first starting plate; the other end of the first transmission piece is hinged and fixed; the second transmission piece drives a presser foot lifting thread-scissoring component to move; the first reset spring is used for resetting the second transmission piece; the second transmission piece is connected with a main transmission rod in the presser foot lifting thread-scissoring component; an elongated hole extending along the vertical direction is formed in the second transmission piece; a shaft bolt fixedly connected with the first starting plate penetrates in the elongated hole. According to the driving mechanism and the buttonholing machine, the degree of automation is high; the connection time between every two adjacent actions is shortened; the working efficiency is improved; the labor intensity of workers is decreased greatly.

Description

technical field [0001] The invention relates to a buttonhole machine, in particular to a driving mechanism for thread punching and presser foot lifting and thread trimming and a buttonhole machine using the same as the driving mechanism. Background technique [0002] Buttonhole machine is a very important equipment in clothing machinery. Buttonhole machine is mainly used to process buttonholes in various clothing. . Among them, the flat buttonhole machine is an industrial sewing machine specially used for sewing buttonholes. In addition to the most basic structure of ordinary sewing equipment, it also adds a swing needle (to realize the swing of the needle bar) and a displacement mechanism, a cutter mechanism, a thread trimmer mechanism, and a brake speed change control mechanism. For example, Chinese patent ZL201310230678.4 discloses a flat-head buttonhole machine, which includes a base and a head housing, and an upper shaft is fixed inside the head housing, and one end o...
