Direct drive structure of sewing machine

Abstract

The invention provides a direct drive structure of a sewing machine and belongs to the technical field of sewing machines. The invention solves the problems that the existing direct-drive sewing machine is not ideal enough in the aspects of mounting, operating and maintenance, and the like. The direct drive of the sewing machine comprises a machine head of the sewing machine, wherein a motor locating plate is fixedly arranged on one end surface of the machine head of the sewing machine; a motor stator is fixedly arranged on the motor locating plate through a through hole arranged in the outer ring of the motor stator; a motor rotor is arranged in the motor stator; one end of the rotor is connected with a main shaft of the sewing machine, and the other end of the rotor is fixedly connected with a hand wheel of the sewing machine; the motor stator and the motor locating plate are all arranged in a machine head enclosure; and the hand wheel of the sewing machine extends out of an opening of the machine head enclosure. The direct drive structure of the sewing machine has the advantages of ingenious concept on structure, good heat dissipation effect, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a direct-drive structure of a sewing machine. Background technique [0002] With the continuous improvement of the level of science and technology, sewing machines have gradually realized automation. Originally, the motor of the sewing machine was hung under the sewing machine table. In order to improve this structure, a direct drive sewing machine was developed. [0003] At present, direct drive sewing machines have also been well developed and applied. The structure of the direct drive sewing machine is: a motor is arranged on the rear end of the machine head, one end of the motor shaft is connected to the main shaft, and the other end is connected to the hand wheel. During the assembly process of this structure, the motor needs to be installed on the machine head. At the end, due to the heavy weight of the motor, there are many inconveniences in the assembly process....

AI Technical Summary

Problems solved by technology

The structure of the direct drive sewing machine is: a motor is arranged on the rear end of the machine head, one end of the motor shaft is connected to the main shaft, and the other end is connected to the hand wheel. During the assembly process of this structure, the motor needs to be installed on the machine head. At the end, due to the heavy weight of the motor, there are many inconveniences in the assembly process. At the same time, this direct drive connection is prone to high errors, resulting in unstable rotation of the sewing machine spindle, which is not enough for installation, work or maintenance. ideal
