The machine head is the main part of the sewing machine. It consists of four mechanisms: piercing, hooking, picking, and feeding, and auxiliary mechanisms such as winding, pressing, and dropping teeth. The movements of each mechanism are reasonably coordinated and work in a cycle to sew the sewing materials together.
The machine base is divided into two types: table and chassis. The table 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 table tops, including one-bucket or multi-bucket folding type, cabinet type, desk type, etc. 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 keep.
The transmission part of the sewing machine is composed of components such as the frame, hand crank, or motor. The frame is the pillar of the machine, supporting the table and foot pedal. When in use, the operator steps on the foot pedal to drive the rotation of the pulley through the crank, and then drives the machine head to rotate through the belt. Most hand cranks or motors are directly installed on the machine head.
The accessories of sewing machine include needle, bobbin, cutter, oil bottle, etc.
