Computerized Flat Knitting Machine Develops Towards Multi Needle Distance Special Function.

A comprehensive survey of the fifteenth Shanghai Textile Industry Exhibition

Efficiency is the main feature.

Since the introduction of multi needle distance and "knit wear" by stor, the island has introduced sliding needle technology and multi needle beds. After opening the open head, the computer flat knitting machine has few new models in recent years. As the computerized flat knitting machine has gone from "high-end" to "Popularization", in order to meet the requirements of the popularization of computerized flat knitting machines in China, and in order to compete with the increasingly powerful domestic computerized flat knitting machines, the famous foreign computer flat knitting manufacturers are making a lot of efforts to improve the production efficiency of the machine.

German Stoll company first proposed the concept of fast reentry, claiming that the production efficiency of computerized flat knitting machine could be increased by 15%~20% on the original basis, and later the "HP" series of efficient computers was introduced.

The company also refused to be outdone. In a timely manner, the "quick turning head system" was introduced, and the weaving efficiency was improved. At the same time, the speed of the head held in 1.2 meters per second was increased to 1.4 to 1.6 meters per second in some models by using the sliding needle Technology.

The domestic computerized flat knitting machine has not been breakthroughs in this respect. At this exhibition, the Ningbo Yulin company adopted the Italy Logica control system, and also introduced the HP series computerized flat knitting machine. The computerized flat knitting machine optimized the knitting process to reduce the head reentry time and the width of the head. It was said that the knitting efficiency could be increased by 10% to 12%.

Widely used and popularized multi needle spacing

Stoll international held the first China International Conference in Beijing in 1998.

Japan island fine Knitting Machinery Co., Ltd. exhibited its machines using "multi needles" technology and extra large (LL) needle hooks for knitting coarse needle products.

In the domestic computerized flat knitting machine, the variable needle distance mainly focuses on 3~5~7 needles and 5~7 needle equipment, and can be used to weave products close to 3 pins to 7 needles. The technology has matured (it should be said that 5 knitted products are more mature).

Changshu Jinlong Company has launched the 14 needle multi needle distance computerized flat knitting machine, which can knit 9~14 needles. It should be a breakthrough in the machine number of the domestic multi needle distance computerized flat knitting machine.

Japan's Pine Valley Machinery Co., Ltd. has exhibited its own patented variable stitch computerized flat knitting machine. This device not only makes articles on the size of the needle hook of the machine, but also has a technology of double tooth flaps, that is, when the needle is knitted, two pieces of tooth pieces are installed at every stitch distance, and a piece of tooth piece is knitted by a needle, so that when the 6 needle product is knitted on the 12 needle machine, the coarser yarn can be allowed to be twisted and dewound, closer to the style of the 6 pin computerized flat knitting machine.

Economic machines meet domestic demand

The economical model is not only a demand of the popular computerized flat knitting machine market, but also an important market demand for the use of computerized flat knitting machine instead of manual flat knitting machine in our country.

A few years ago, Changshu Jinlong and other companies first launched the single system computerized flat knitting machine, which became a special product in the computerized flat knitting machine market in China. After several years of development, it has become increasingly mature and the price is becoming cheaper. The price of the single computer flat knitting machine of the general insert type needle bed is around 6~9 yuan, while the single computer flat knitting machine of the milling needle slot has dropped to about 40 thousand yuan to meet the needs of small enterprises.

The single segment needle selection machine introduced by Nantong Tianyuan company has reduced the cost of the machine because of the reduction of machine parts and size, and the price of the machine has been greatly reduced. The price of a 4 system machine is only 80 thousand yuan at the exhibition.

Jiangsu Sheng Xing also exhibited the SXC-132E-1L single segment needle selecting computerized flat knitting machine at the exhibition, which made the machine structure miniaturized, the machine parts reduced and the technical level improved.

The famous brands of computerized flat knitting machines such as stor, Jing Jing and Tan Tan did not produce single computer flat knitting machines, but they also introduced economical flat knitting machines. This exhibition focused on the introduction of CMS502 series economical computerized flat knitting machine. By reducing the size of the needle bed, reducing some of the non main parts and reducing the price of the machine, the competitiveness of the computer flat knitting machine was improved.

The island precision company focused on the introduction of their SSR112-SV flat knitting machine, reducing the width of the needle bed and other measures.

A special function machine is unique.

Although the domestic computerized flat knitting machine is large in scale, many factories and many machines, the homogenization of the machine is obvious. It is basically the same as the design system, the machine structure and the main parts.

Some special function computerized flat knitting machines are still on display by several foreign manufacturers. They are mainly woven and wearable (Quan Chengyi) models and applique models.

German Stoll and Japan island fine company respectively exhibited their CMS830C double needle bed "woven wearable" models and MACH2X153 four needle bed full garment models.

The CMS830C double needle bed "woven and wearable" is a single machine head with variable 2 times coil density adjustment (2 stages) function, optional applique yarn guide and yarn feeder, optional automatic coil control system for knitted knitted fabric.

MACH2X153 four needle bed full garment model single head, with 4 needle beds, 2 of which are knitting needles, 2 needle beds for turning needles, no knitting function, electromagnet direct needle selection, sliding pin type (SlideNeedle) full molding needle, lower head two sections, with controllable presser feet, fixed sink and i-DSCS intelligent numerical control yarn ring system and DSCS numerical control yarn ring system, the maximum speed can reach 1.6 meters / sec, optional air splicer, full needle knitted all ready made products.

The company also displayed their applique computerized flat knitting machines.

The function of the Aries3.130 type computerized flat knitting machine of the Tanger company is the 3 position needle selection and the integrated minute hand function. The unique opening head is used for feeding the yarn directly on the top, and the 32 guide yarn is driven by an independent stepping motor. As an advanced way of feeding yarn, it is unique in the applique computerized flat knitting machine.

Island fine company MACH2SIG123-SC double needle bed, single head, 3 position needle selection, with controllable presser feet, spring type movable sinker, main and auxiliary traction roller, floor, i-DSCS intelligent numerical control yarn ring system and DSCS numerical control yarn ring system, 40 lead Tasia (mosaic) guide yarn, maximum speed of 1.4 m / sec.

Stuart CMS822HP multi pin computer flat knitting machine adopts separable and double head, 2 x 2 system, three needle selecting knitting and turning needle, main and auxiliary traction roller, with bottom plate, it can also braze two pieces of fully molded sheet at the same time. With sinker, single stage contactless needle selection, it can bring 32 guide yarn, optional applique guide and yarn feeder, and optional ASCON automatic coil control system.

In the domestic computerized flat knitting machine, Tianyuan, Nantong, has introduced a completely new computerized flat knitting machine. It has developed the double needle bed "shuttle type" computerized applique flat knitting machine, which has been developed in recent years. It has developed a double needle bed "computer shuttle knitting machine", which adopts the technology of automatic shutting and placing needles, automatically changing the yarn and putting the needle, manually hanging the rib and picking the needle, and the computerized flat knitting machine. The machine adopts the imitation hand applique connection mode, and achieves the connection between adjacent color blocks through the yarn's stranding, making the connection more smooth and without holes.

In addition, as the machine is a double needle bed machine, it can automatically start and weave. It can also combine various patterns and applique of the computerized flat knitting machine when weaving, enriching the pattern weaving ability of the traditional single needle bed applique products.

The machine can also be woven like ordinary computerized flat knitting machine without needing to inlay flowers.

Practicing internal strength from imitation to innovation

Although the exhibition of computerized flat knitting machines is still very hot at this exhibition, there are new manufacturers joining in the manufacture of computerized flat knitting machines. There are more than 10 manufacturers of computerized flat knitting machines with an annual production capacity of more than 5000. However, the reduction of orders in the two quarter of this year has made the manufacturers look at their products and markets again.

This turning point or turning point is also a good thing in a sense, so that the industry can win the fittest, so that enterprises can make new efforts on the basis of practicing internal strength and increasing strength.

There may be three main tasks here: first, the production enterprises of computerized flat knitting machines should strengthen their internal production management, start with standardization of spare parts and assembly, pform from extensive production to fine processing according to the requirements of industrial engineering, make production efficiency higher, produce better product quality, higher reliability, better stability, lower rework rate and lower service cost.

Two is to strengthen product development efforts, on the basis of traditional products, efforts to increase new varieties, expand new functions, in the production efficiency, reliability and adaptability of the machine for further research and development, especially to strengthen the knitting process, mechanical assembly processing and computer control hardware and software aspects of cooperation, so that the design and production of computerized flat knitting machine from imitation to innovation, from knowing it to knowing it, so as to continuously enhance the core competitiveness of products.

The three is to continuously expand and cultivate the technical team, so that the machinery design and manufacture, knitting technology and electronic and computer technicians in the industry will continuously improve their level and experience to meet the needs of product development, design, manufacture and after-sales service.

In short, for China's computerized flat knitting machine industry, through the development and market test in recent years, we already have the economic strength and technological foundation for further development and improvement. Next year's ITMA ASIA+ CITME 2012 international textile machinery exhibition, even if there will not be more computer flat knitting machines exhibitors, more new products will emerge, making our computer flat knitting machine industry go to a new level.
