Three System Shoe Upper Knitting Machine Series

QL-336X QL-352X QL-372X QL-380X

Triple system 3D Shoe Upper Knitting Machine specialized in making shoe uppers with high production efficiency. This series is a fully automatic computer knitting machine without a bottom plate device. It uses digital technology to realize the functions of transfer, tuck, intarsia without dotted lines, jacquard, embroidery, open narrowing, and other regular pattern knitting functions.

It can weave basic knitting weaves, multi-color random jacquard, intarsia, twisted flowers, pick holes, and other weft weaves.

It is also suitable for knitting shoe uppers and other accessories with raw materials such as silk, spun silk, synthetic fiber, wool, rayon, and blended yarn. They are the mainstream machines for the professional production of 3D shoe uppers.

Product Characteristics

Automatic Refueling

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

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.
Main Parameter


QL-336X  QL-352X  QL-372X  QL-380X




Single carriage with the three system

Knitting range


Knitting system

Single carriage with the three system

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


By using the control principle of the cross sinker, more lines of local braiding can be carried out, which plays a positive role in the braiding of complex tissues. Independent signal, subsystem control.

Presser device

One set of presser feet(optional)

Take-up device

128 sections of automatic control, time division adjustment, can be automatically identified according to the width of the pattern automatically adjust the tension, can meet a lot of local weaving, The pulling force requirement of the pattern makes the pulling force of the fabric evenly distributed and the strength is reliable.

Yarn feeder device

The roller feeding device can precisely control the tension of the yarn and ensure the consistency of the whole fabric quality.

Safety device

The whole machine is covered to reduce noise and dust. infrared safety device, emergency stop device, cut off the 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, a touch screen graphical interface transmission mode uses USB and a network, which can be used to store a large number of pattern files and be called out and used at any time according to production needs. Monitoring screens display all kinds of working parameters and knitted mesh values, and they 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 lower format CNT, HCD,000. etc. Support for multi-language operating versions (Chinese, English, Russian, and other languages)

 Data input

Input data through a USB flash drive or computer connection

Blackout memory function

Advanced CMO technology is adopted to realize blackout memory and call recovery weaving functions.

Network function

A high-speed ETHERNET network theoretically enables unlimited computer connection, data uploading and sharing, and real-time monitoring.

Power supply unit

Voltage: AC 220V/380V; Frequency: 50HZ/60HZ; Power: 1.5KW

Size and weight of the machine

QL-352X14G ( Size:2600*800*1700MM; Weight around:880KG)

Specifications And Configurations Should Be Subjected To The Contract.

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.
