Industrial sewing machine is a kind of sewing machine suitable for mass production of workpieces in sewing factories other industrial departments. Industrial sewing machines are used in clothing, shoes, hats other factories that need sewing machines.

1、 When sewing, the thread take-up mechanism sewing machine plays the role of conveying, recovering tightening stitches in the process of forming stitches. It can be classified as follows:

1. Cam thread take-up mechanism: the mechanism that the cam drives the thread take-up rod to move

2. Connecting rod thread take-up mechanism: a mechanism driven by a four-bar mechanism

3. Sliding rod thread take-up mechanism: it is a mechanism driven by crank sliding rod mechanism

4. Rotary thread take-up mechanism: a mechanism for thread take-up movement, which consists of one two discs other shaped components with thread take-up pins

5. Needle bar thread take-up mechanism: it is composed of thread passing clamping device fixed on needle bar, thread take-up mechanism directly fixed on needle bar.

2、 Feeding mechanism

A mechanism for delivering sewing material when a sewing machine is sewing. Its classification is: forward feeding mechanism; backward feeding mechanism; transverse feeding mechanism; lower feeding mechanism; upper feeding mechanism; needle feeding mechanism; upper lower composite feeding mechanism; upper needle composite feeding mechanism; needle lower composite feeding mechanism; upper, needle lower composite feeding mechanism; upper, needle lower composite feeding mechanism; differential feeding mechanism; roller feeding mechanism.

3、 Hooking mechanism

When a sewing machine is sewing, after the needle belt guides the thread through the loop formed by the sewing material, a mechanism that hooks the loop to form a stitch. Its classification mainly includes: rotary hook mechanism; rotary hook mechanism; rotary hook mechanism; swing hook mechanism; swing hook mechanism; looper hook mechanism; thread hook mechanism; fork needle hook mechanism.

4、 Trip of take-up pole

The distance between two threading holes on the take-up pole in a cycle of motion

5、 Needle rod stroke

The distance of a point on the needle bar between two positions of needle bar movement

6、 Sewing speed

The number of needle punches per minute of the sewing machine, unit: needle / min; sewing speed: the number of needle punches that the sewing machine can bear under normal sewing conditions; working sewing speed: the sewing speed that the sewing machine can bear continuous operation under normal sewing conditions.

7、 Stitches

Sewing thread. Generally made of cotton thread, chemical fiber thread, metal wire, etc. The main categories are: needle thread; shuttle thread; curved needle thread; stretch thread; covering thread

8、 Trace

When the needle of a sewing machine passes through the sewing material each time, it is a unit formed by one more stitches, which are self connected, mutually connected interweaved on the sewing material.

9、 Presser foot

A component that exerts pressure on the surface of a seam. According to the performance of sewing machine, presser foot can be divided into flat sewing machine presser foot, wrapping sewing machine presser foot special machine presser foot. According to its function, presser foot can be divided into ordinary presser foot special presser foot. There are many kinds of special presser foot, such as crimping presser foot, feeding presser foot, double needle presser foot, etc.

10、 Cutting device

In the sewing process, the cutting device is used. There is a device for cutting the waste edge of sewing material in the overlock sewing machine flat sewing machine with knife. In a sewing machine for sewing leather, there is a device for cutting waste leather. In the automatic sewing machine, there is a device for cutting sewing materials such as thread belt decorative belt.

11、 Opening device

A device for opening holes in sewing material during sewing. A device for opening a lock hole in a keyhole machine. A device with flower holes in an embroidery machine.

12、 Other devices

Other devices include: automatic thread pulling device, automatic thread cutting device, automatic needle stop device, oil suction device, lubricating device, etc.
