What are the main components of an industrial sewing machine?

​

Industrial sewing machine (industrial sewing machine) is a sewing machine suitable for sewing workpieces for mass production in sewing factories or other industrial sectors. Industrial sewing machines are used in factories that require sewing machines for clothing, shoes and hats, etc.

1. Take-up mechanism

When the sewing machine is sewing, in the process of forming stitches, it plays a role in conveying, recovering needles and threads and tightening stitches.

Mainly can be divided into the following:

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

2. Connecting rod thread take-up mechanism: a mechanism driven by a four-bar linkage mechanism to move the thread take-up mechanism

3. Slider thread take-up mechanism: a mechanism driven by the crank slider mechanism to move the thread take-up mechanism

4. Rotary thread take-up mechanism: a mechanism that uses one or two discs or other shaped components equipped with thread take-up pins to perform thread take-up movement with a rotating motion

5. Needle bar thread take-up mechanism: a mechanism that fixes the thread passing or clamping device on the needle bar, or directly fixes the thread take-up bar mounted on the needle bar.

2. Feeding mechanism

When the sewing machine is sewing, it is the mechanism for delivering the sewing material. Its classification is: forward feeding mechanism; reverse feeding mechanism; horizontal feeding mechanism; lower feeding mechanism; upper feeding mechanism; needle feeding mechanism; upper and lower compound feeding mechanism; upper and needle compound feeding mechanism; ; Upper, needle and lower integrated feeding mechanism; Differential feeding mechanism; Roller feeding mechanism.

3. thread hooking mechanism

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

4. Take-up lever stroke

The threading hole on the thread take-up lever is the distance between the two extremes in one cycle of movement

5. Needle bar stroke

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

6. Sewing speed

The number of needle punches per minute of the sewing machine, the unit is: needles/min, the maximum sewing speed: the maximum number of needle punches that the sewing machine can withstand under normal sewing conditions; working sewing speed: the sewing machine can withstand continuous safe operation under normal sewing conditions the highest sewing speed.

Seven, suture thread

Thread for sewing. Generally, it is made of cotton thread, chemical fiber thread, metal wire, etc. The main categories are: needle thread; shuttle thread; looper thread; stretch thread; covered thread

Eight, stitch stich

A sewing machine needle is a unit formed by one or more sutures that are self-connected, mutually or interwoven on the sewing material each time the sewing material is passed.

Nine, presser foot presser

A member that exerts pressure on the surface of the sewing material. Presser feet can be divided into lockstitch sewing machine presser feet, overlock sewing machine presser feet, and special machine presser feet according to their sewing machine performance. Presser feet are divided into ordinary presser feet and special presser feet according to their functions.

There are many types of special presser feet, such as curling presser feet, feeding presser feet, double-needle presser feet, etc.

10. material trimming device

During sewing, cut off the sewing material unit. There is a device for cutting off the waste edge of the sewing material in the overlock sewing machine and the lockstitch sewing machine with a knife.

There is a device for cutting waste leather in the sewing machine for sewing leather. In the automatic sewing machine, there is a device for cutting sewing materials such as thread tape and decorative tape.

11. Hole opening device punching winder

A device for making holes in the sewing material during sewing.

There is a device for opening keyhole holes in the keyhole machine. There is a device for opening pattern holes in the embroidery machine.

12. Other devices

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