Sewing machine type

Household sewing machine

In the early days, it was basically a single-needle, hand-operated sewing machine, and later invented an electric-driven sewing machine, which has always been the mainstream in the market. According to its mechanism and stitch form, it can be roughly classified into JA type, JB type, JG type, and JH type. The picture below shows a type of household sewing machine - JG type household electronic multi-function sewing machine.

Industrial sewing machine

Most of the industrial sewing machines are general sewing machines, including sewing machines, chain stitching machines, quilting machines, overlock machines and stretch sewing machines, and the sewing machine has the highest usage rate.


Component

The general sewing machine consists of four parts: the nose, the base, the transmission and the attachment.

The nose is the main part of the sewing machine. It consists of four mechanisms: thorn material, hook line, thread take-up, feeding mechanism and auxiliary mechanisms such as winding, pressing and dropping. The movement of each mechanism is reasonably matched, and the work is cycled to stitch the sewing material.

The base is divided into two forms: platen and chassis. The platen of the platen frame plays the role of supporting the head and is used as a table during sewing operations. The platen has a variety of styles, including a bucket or a multi-bucket, a cabinet, a writing desk, and the like. The chassis of the chassis-type base serves to support and store the head, making the sewing machine easy to carry and store.

The transmission part of the sewing machine consists of a frame, a hand crank or a motor. The frame is the backbone of the machine and supports the table and foot pedals. When in use, the operator steps on the pedal, rotates the pulley through the crank, and rotates through the belt with the motive head. Most of the hand shaker or motor is mounted directly on the handpiece.

Accessories for the sewing machine include needles, bobbins, screwdrivers, oil cans, etc.
