Problems solved by technology

When processing on a lockstitch sewing machine, it is necessary to continuously push the fabric forward manually. The speed of pushing the fabric is mainly based on the operator's experience, which leads to unstable product quality. In order to improve the sewing quality, a feeder is usually installed on a higher-end sewing machine. Mechanism, but the existing feeding mechanism and the lockstitch sewing machine are both independently operated and cannot cooperate well. For example, when the sewing machine stops working, the puller still pulls the cloth to move, or when the puller stops working, the sewing machine is thrown in the sewing, which will affect sewing effect
[0003] In order to solve the above problems, the application number is 201210093685.X, which discloses a material pulling device and a presser foot lifting device of a multi-needle machine. The problem that the foot lifting mechanism cannot cooperate, but the structure and function of the multi-needle machine and the lockstitch sewing machine are not the same, so how to solve the problem of cooperation between the material puller and the presser foot on the lockstitch sewing machine is an urgent need in the sewing machine production industry. solved problem

Abstract

The invention relates to the technical field of sewing machines, in particular to a lockstitch sewing machine capable of feeding automatically. The lockstitch sewing machine comprises a lockstitch sewing machine body, a presser foot arranged on the lockstitch sewing machine body, a material puller and a link gear, wherein the material puller comprises a mounting plate, a synchronous pulley, an tension roller, a material pulling roller, a material pulling belt and a stepping motor, the mounting plate is fixed on the lockstitch sewing machine body, the synchronous pulley, the tension roller and the material pulling roller are arranged on the mounting plate and can tension the material pulling belt, the material pulling roller is capable of rotating up and down around the tension roller, and the stepping motor is connected with the synchronous pulley and drives the same to rotate, and the link gear is connected with the presser foot and the material pulling roller so as to drive the material pulling roller to move up and down along with the presser foot. The lockstitch sewing machine is compact in structure and convenient to use, and via linkage matching of the material puller and the presser foot, patterns sewn by the lockstitch sewing machine are uniform and attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a lockstitch sewing machine which can automatically feed materials during sewing. Background technique [0002] Existing, lockstitch sewing machine mainly is to use a sewing thread, forms a kind of stitching on sewing material, makes one or more layers of sewing material interweave or sew up the machine. When processing on a lockstitch sewing machine, it is necessary to continuously push the fabric forward manually. The speed of pushing the fabric is mainly based on the operator's experience, which leads to unstable product quality. In order to improve the sewing quality, a feeder is usually installed on a higher-end sewing machine. Mechanism, but the existing feeding mechanism and the lockstitch sewing machine are both independently operated and cannot cooperate well. For example, when the sewing machine stops working, the puller still pulls the cloth to move, or when th...
