Any machine is composed of many accessories. Generally, sewing machines are composed of four parts: head, base, transmission and accessories.
The head is the main part of the sewing machine. It is composed of four mechanisms of material stabbing, thread hooking, thread take-up and feeding, and auxiliary mechanisms such as thread winding, material pressing, and tooth dropping. The motion of each mechanism is reasonably coordinated, working in cycles, and sewing the sewing materials together.
The base is divided into two forms: table plate and case. The platen of the platen type machine base plays a role of supporting the machine head and is used as a worktable during sewing operations. There are many styles of tabletops, including one bucket or more buckets, folding Tibetan type, cabinet type, writing desk type, etc. The case of the case type machine base plays a role of supporting and storing the machine head, making the sewing machine easy to carry and store.
The driving part of the sewing machine is composed of parts such as a frame, a hand crank or a motor. The frame is the pillar of the machine, supporting the platform and pedals. When in use, the operator steps on the foot pedal, the crank drives the rotation of the pulley, and the belt drives the head to rotate. Most hand cranks or motors are directly mounted on the machine head.
The above are the main parts of the sewing machine. Of course, it still includes many other parts, such as needles, bobbins, knives, oil cans, etc., which are also indispensable.
