Product Characteristics

Automatic Refueling

In order to make the machine work better, we have developed a 24-hour intelligent system for automatic refueling.


The linear velocity of the head can reach 1.2m/s. The stroke can be adjusted according to the weaving width. Fast response and accurate location can avoid invalid movements and increase production efficiency. Each system is equipped with five functions as rib transfer,weaving, tuck,non-weave, and in. In addition, it is secured by short-circuited electric magnet,motor overcurrent, Locked-Rotor, etc.

Needle Bed

Divided structure, steel sheet made from import high-quality steel precisely punched and finely polished to reduce the resistance with needles and increase the longevity.

Dynamic Stitch

The device by dynamic stitch technology, we achieve the variety of stitches and variety density in one course to improve knitting efficiency and variety.
High-speed and High-efficiency
Increase the carriage return speed and productivity as well as avoid the work of the carriage rail. In the case of 12g, the high-speed return can improve efficiency by more than 20%,compared with the old system.

Positive Yarn Provide

Positive Yarn Providing, successfully Reduce Yarn Resistance, increase Knitting Efficiency.

*roller yarn provider and yarn storage device can be selected according to the model of the machine

Touch Screen

Adopting industrial LCD, graphic interface,color display. On working conditions, ,parameters like weavingpieces, finished pieces, time, velocity,Roller,mesh number, yarn nozzle, etc. could be displayed clearly on the screen. When running,you can adjust parameters freely. This is the most convenient and time-saving device all you need to do is just focus on the fabric and input the command, and then all the parameters and pattern types could be changed.

Knitting system

Single carriage with the double system, the double carriage with the double system (optional); Digital technology is adopted to realize needle turning, hole picking, eye lifting of flat knitting machine.No dotted line jacquard, full needle, open stitch, dark stitch, and other regular pattern weaving functions.

Knitting speed

maximum speed is 1.8 m/s without load, with 128 sections of programming speed.

Stitch density

128 sections electronic control, using subdivision technology; The stepping motor controls and adjusts the density, and the adjustable range is 0-650.


Dynamic stitch

It is realized by a high-speed stepper motor, which supports the realization of multi-segment variable mesh control within a row of patterns, and the realization of a variety of fabric densities in the same line Weaving, rich weaving patterns.


Can be turned back and back at the same time, not affected by the nose direction, minute knitting.

Racking system

Motor-driven, 1/2 and 1/4 needle in any position; Maximum 2 inches on one side.


The stepping motor can adjust the movable sinker, which can be adjusted according to different fabrics to achieve a variety of needling and needling effects.

Quickly turning

An intelligent switching braiding system improves machine weaving efficiency.

Take-down device

128 sections of automatic control, time division adjustment, can be automatically identified according to the width of the pattern force of the fabric evenly distributed and the strength is reliable. The force of the fabric is evenly distributed and the strength is reliable.

Yarn feeder device

1.5G-10G adopts roller feeding device to accurately control the tension of the yarn and ensure the consistency of the whole woven piece quality;

12G- 18g adopts the yarn storage device to accurately control the tension of the yarn and ensure the consistency of the whole woven piece quality;

Safety device

The whole machine is covered to reduce noise and dust, infrared safety device, emergency stop device, cut-off power device, indicator light alarm device.

Refueling device

Automatic refueling: control the refueling time and frequency by setting the time. After the time is up, lubricate the long needle spring needle on the needle plate automatically to reduce the wear of the machine and increase its service life.

Stop motion

Automatic stop for yarn breaking, yarn knot, fabric rewinding, firing pin, number of pieces completed, overload, program error, etc

Control system

the screen uses LCD industrial display, touch screen graphical interface, transmission mode uses USB and network, which can be used l0 store a large number of pattern files, and can be called out and used at any time according to production needs. Monitoring screen: it can display all kinds of working parameters and knitted mesh values, and it can be adjusted at any time when the machine is running, which is convenient for operation and time saving to the greatest extent. Plate-making system and control system (software part) SH upgrade is convenient. Support a variety of flower format CNT, HCD, 000, etc. Support for multi-language operating versions (Chinese, English, Russian, and other languages).

Data input

Computerized flat knitting machine maintenance instruction

To ensure computerized flat knitting machine is in a good situation at any time, reducing wear and increase of the machine life, keep a lower operating and maintenance costs, we need to properly maintain the machine, provide a good working environment. The following points are very important and must be done:
1. Every production unit should be cleaning the needle bed with an air compressor, make sure there is no dust on the needle, yarn feeder, yarn feeder guide rail, out of the carriage, brush…cleaning the workshop regularly.
2. Add lubricant to the needle bed, needle stitch, yarn feeder guide rail, carriage guide rail, keep all the transmission parts lubricated.
3. Machine discontinued using long time or temporary, need to apply with anti-rust oil for the needle bed and other parts at first, the machine also needs to be covered.
4. Please read the instruction manual before using the machine.
