Abstract

The invention relates to the technical field of mechanisms of sewing machines, in particular to a cloth feed mechanism of a sewing machine. The cloth feed mechanism of the sewing machine aims to solve the problems that potential safety hazard exists, cost is high and working efficiency is low in the prior art. The cloth feed mechanism for the sewing machine comprises a cloth feed shaft, a feed lifting rock shaft, a cloth feed crank, a feed frame, a second frame, a first cloth feed dog and a second cloth feed dog, wherein the cloth feed crank is provided with double-end drive ends which are perpendicularly and symmetrically arranged by 180 degrees. The cloth feed mechanism of the sewing machine is characterized by further comprising a feed lifting rock shaft crank, the cloth feed shaft and the cloth feed crank connected with the cloth feed shaft are located at the front portion in the cloth feed direction, the feed lifting rock shaft is a swinging shaft and located at the rear portion in the cloth feed direction, the feed lifting rock shaft crank is of a double-crank structure arranged in the cloth feed direction by 180 degrees, the middle of the feed lifting rock shaft crank is connected with the feed lifting rock shaft, the end of the first feed frame is connected with the crank structure at the front portion through a first feed lifting connection rod, and the end of the second feed frame is connected with the crank structure at the rear portion through a second feed lifting connection rod.

Description

Technical field [0001] The invention relates to the technical field of sewing machine mechanisms, in particular to a cloth feeding mechanism for sewing machines. Background technique [0002] In the patent No. "2012200223171", a continuous cloth feeding mechanism for a sewing machine is disclosed. The continuous cloth feeding mechanism includes a cloth feeding shaft, a lifting shaft, a cloth feeding crank, a first bracket, a second bracket, The first feeding dog, the second feeding dog, the first raising link, the second raising link and the raising cam. The lifting cam is a double cam structure arranged symmetrically at 180°, a first lifting link and a second lifting link are arranged on the lifting cam, and the cloth feeding crank includes a vertical 180° symmetrical arrangement The double-headed driving end; the first tooth frame is arranged between one driving end of the cloth feeding crank and the action end of the first lifting link, the second tooth frame is arranged betw...
