3D Shoe Upper Knitting Machine

QL-336X QL-352X QL-372X QL-380X QL-436X QL-452X QL-472X QL-480X

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.

Knitting system

Triple system Quadruple system

Knitting speed

Maximum speed is 1.8 m/s without load, with 128 sections of programming sped

Stitch density

128 levels, electronically controlled, using subdivision technology; The stepping motor controls and adjusts the density; The adjustable range is 0-650.

Dynamic stitch

Using high speed stepping motor, the multi-stitch function can be achieved in one line.

Transfer

Simultaneous transfer, front or back, independent of carriage direction. They can split stitch possible without exchanging yarn carriers

Racking system

Motor-driven. 1/2 and 1/4 needle available from any position.Max 2 inches racking to each side.

Sinker

By using the control principle of 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

Positioned on front and back presser(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 devices

Fill safety cover for noise suppression and dust-proofing Infrared security device. Emergency stop switch, Emergency power of device, Operation 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

Yarn break, large knot, fabric pileup, shock detection, piece count,over-torque, program error, Etc.

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.
