Components of a sewing machine
General sewing machines are composed of four parts: head, base, transmission and accessories.
The machine head is the main part of the sewing machine. It is composed of four mechanisms: barbed material, hook thread, thread take-up and feeding mechanism, and auxiliary mechanisms such as thread winding, material pressing, and tooth-dropping.
The base is divided into two forms: platen and chassis. The platen of the table-type machine base plays the role of supporting the machine head and is used as a workbench during sewing operations. There are many styles of tabletops, such as one-bucket or multi-bucket folding Tibetan type, cabinet type, writing table and so on. The chassis of the chassis-type machine base plays the role of supporting and storing the machine head, making the sewing machine easy to carry and store.
The transmission part of the sewing machine is composed of parts such as a frame, a hand crank or a motor. The frame is the backbone of the machine, supporting the deck and footrests. When in use, the operator steps on the pedal, drives the rotation of the pulley through the crank, and drives the head to rotate through the belt. Most hand cranks or motors are directly mounted on the nose.
Accessories for sewing machines include needles, bobbins, screwdrivers, oilers, etc.
