Sewing machine components

         The general sewing machine is composed of four parts: machine head, machine base, transmission and accessories. The head is the main part of the sewing machine. It consists of four mechanisms: barbed material, hook thread, thread take-up, feeding, and auxiliary mechanisms such as winding, pressing, and tooth falling. The movement of each mechanism cooperates reasonably and works cyclically to sew the sewing material.

        The base is divided into two forms: table and chassis. The table of the table-type base plays the role of supporting the machine head, and is used as a work table during sewing operation. There are many styles of table tops, including one or more buckets of folding type, cabinet type, writing desk, etc. The chassis of the chassis-type 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 a frame, a hand crank or a motor. The frame is the pillar of the machine, supporting the table and foot pedals. During use, the operator steps on the foot pedal, drives the rotation of the pulley through the crank, and rotates the head of the motor through the belt. Most hand cranks or motors are directly mounted on the machine head.

        Accessories for sewing machines include needles, bobbins, screwdrivers, oil pots, etc.
