What is the composition of the electric sewing machine

Sewing machine is a sewing machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that a layer or layers of sewing material are intertwined or sewn together. Sewing machine can sew cotton, linen, silk, wool, man-made fibers and other fabrics and leather, plastic, paper and other products, sewing out of the seam neat and beautiful, flat and firm, sewing speed, easy to use.

There are many ways to categorize sewing machines, the more common is to distinguish by stitch and use. Sewing machine stitch can be summarized into two categories: lockstitch and chainstitch. Lock stitch is the most common, it consists of two sewing threads, intertwined with each other like a rope, the intertwining point in the middle of the sewing material. From the cross-section of the stitch, the two threads are interlocked like two locks, and are thus called lock stitch. This kind of stitch is used in cotton, woolen fabrics or leather with small shrinkage, and the shape of the front side and the back side are the same, like a dotted line. The stitch is densely distributed and the fastness of sewing generally exceeds that of hand sewing.

Chain stitch is made by the thread of the sewing thread of the loop self-connecting or interconnecting, commonly used single-thread chain, double-thread chain and three-thread overlock stitch. This type of stitch is characterized by elasticity and can be stretched along with the sewing material without breaking the thread, and is suitable for sewing garments made of elastic fabrics or overlocking products and blanks that are easily loosened.

The general sewing machine consists of four parts: the head, the seat, the drive and the accessories.

The head is the main part of the sewing machine. It consists of four mechanisms, namely, stabbing, hooking, picking and feeding, and auxiliary mechanisms, such as winding, pressing and dropping teeth, etc. The movements of the mechanisms work reasonably well together and circulate the work to sew the sewing material together.

The machine base is divided into two forms: table plate and chassis. The table plate of the machine base plays the role of supporting the head of the machine, and is used as a worktable during sewing operation. There are many kinds of table boards, including one or more buckets of folding type, cabinet type, writing desk type, etc. The chassis type of machine base has two types: one is for the head of the machine and the other is for the sewing machine. The chassis of the chassis-type machine base plays the role of supporting and storing the machine head, so that the sewing machine is easy to carry and storage.

The transmission part of the sewing machine consists of the frame, hand crank or motor and other components. The frame is the pillar of the machine, supporting the table plate and foot pedal. When in use, the operator steps on the foot pedal, through the crank to drive the rotation of the pulley, and through the belt to drive the machine head rotation. Most of the hand cranks or electric motors are mounted directly on the machine head.

Accessories for sewing machines include needles, bobbins, openers, oil jugs, and so on.
