Do You Know What A Knitting Machine Is Made Of

There are many types of knitting machines, but no matter what type of knitting machine, their main structure is basically the same, but knitting is different according to the working requirements of various machines, and the specific structure is different, and there are auxiliary mechanisms for different purposes. . The mechanism of the machine can be roughly divided into two parts, namely the main mechanism and the auxiliary mechanism.

(1) The main mechanism of the knitting machine

1. Loop forming mechanism

The loop-forming mechanism is a mechanism that bends the yarn to form loops and sets the loops together to form a knitted fabric. The main parts are knitting needles, sinkers, cams and yarn guides. These parts are collectively referred to as loop forming parts. They are driven or fixed by the main shaft through their respective transmission mechanisms and cooperate with each other to form a loop.

2. Yarn feeding mechanism

The yarn feeding mechanism is a mechanism that sends the yarn on the bobbin or warp beam to the loop forming machine at a certain tension and speed according to the requirements of the knitting system.

3. Design agencies

The pattern mechanism is called the needle selection mechanism in weft knitting, and its function is to select knitting needles or sinkers according to the requirements of the pattern. The pattern mechanism is called the bar transverse movement mechanism in warp knitting. Its function is to control the bar fixed with the guide needle, and make it move the needle front and needle back transversely in the direction of the needle bed according to the pattern required by the pattern.

4. Transmission mechanism

It is a mechanism that uses the main shaft as the main body, through various transmission parts such as cams, eccentric connecting rods, worm gears and gears, to make various parts of the machine move.

5. Control mechanism

It is an organization that enables organizations to coordinate their work in accordance with the weaving requirements.

6. Pull and take-up mechanism

It is a mechanism that draws the fabric from the weaving area and rolls it into a cloth roll with a certain tension and speed.

 (2) Auxiliary mechanism of knitting machine

1. Deceleration device

 In order to adjust the machine, the knitting machine is equipped with a deceleration device to make the machine run slowly, which is convenient for maintenance and adjustment.

2. Self-stop device

It includes automatic stop devices such as machine failure, safety, yarn breakage, cloth surface defects, excessive or small tension, and package capacity limitation.

3. Various meters

Knitting machines are equipped with machine tachometer, let-off speed meter and counter according to different models.

4. Expansion of institutions

It includes jacquard mechanism, yarn pressing rod, pattern pressing plate, intermittent let-off and multi-speed let-off.
