Qi Limin: Production And Use Of New Air-Jet Looms

The main product of Qingdao Tianyi red flag spinning machine is air-jet loom and roving machine. It has more than 10 years of production history and the annual production capacity of the company can exceed 400 million yuan.

At present, the air-jet looms of Tianyi red flag sell well both at home and abroad, with more than 10 thousand market shares.

Tianyi Hongqi's products are located in high-end customers. Now it has formed close cooperation with many well-known enterprises, such as Huafu group, Hengfeng group, Shandong Ruyi home textile company, and so on.

And industry influence.

It is characterized by fast running speed, high production efficiency, less machine material consumption, reasonable weft insertion and safe operation. Therefore, it has become the fastest developing and most promising machine in shuttleless looms, but practice shows that air jet loom energy consumption is the indisputable fact of shuttleless looms.

It has always been a hot topic in the development of air-jet looms.

Air jet looms auxiliary nozzle, main nozzle, air ring cover and WBS, energy saving control of weft insertion system, use of energy saving nozzles and energy saving reeds, beating up and shedding mechanism and air compressor all affect the energy consumption of air-jet looms.

In particular, the consumption of auxiliary nozzle occupies more than 75% of the air consumption of the weft insertion system, and the performance of the auxiliary nozzle is the key to saving energy and reducing consumption.

The outlet nozzle of the auxiliary nozzle is changed from cylindrical to inner conical, which can increase the pressure of the bundle like jet by 50%, and achieve the purpose of saving gas.

At present, the number of solenoid valves that control the auxiliary nozzles is increased, and 5 auxiliary nozzles are changed to 2 or 3 from a previous solenoid valve, so as to achieve the purpose of short distance relay injection for air flow and save energy consumption.

The test saves energy consumption by 10%~15%.

This improvement reduces the energy consumption of customers, but increases the cost of the whole machine.

With the rapid development of the individuation and quality of textile products, the quality requirements of the downstream enterprises of cotton textile have improved.

Due to cost and other factors, cotton textile enterprises will consider making some scientific and reasonable adjustment in raw material blending with cotton spinning.

Therefore, Zhejiang Jinfeng Textile Machinery Co., Ltd. has developed the JZX - "5" comb, sawtooth combined high efficiency comber comb.

According to the performance and sawtooth characteristics of the comb pin, the circular comb design of the high efficiency cotton comber is optimized and the carding ability is further improved.

However, combing fiber needs combing force, and the carding force is not enough, which will cause the fiber bundles not to open, resulting in fiber bundles. Too much combing force will lead to fiber damage, increase short staple, aggravate the abrasion of the needle teeth, even break the needle and break the teeth, and increase the energy consumption of the equipment.

Therefore, the design of the circular needle and saw tooth has been greatly improved. The round comb needles ensure the sharpness and roughness of the front end, and ensure the taper of the rear end. The saw tooth piece adopts the technology of stamping and grinding on both sides of the tooth surface to ensure the smooth tooth tip, tooth root and tooth surface.

At the same time, in order to adapt to the high speed and large quantitative process requirements, avoid inserting, loosening and finishing of the front row sawtooth puncture cotton layer, and better integrate the advantages of the needle cylinder and the sawtooth cylinder to ensure the best puncture effect.

The needle tooth height of the needle bar and the tooth piece is deep and shallow in the front row, which reduces the filling of the fiber to the cylinder and improves the carding effect of the fiber and cylinder.

Such a tin Lin design, consciously Sn forest is divided into two areas, to ensure the high speed of the carding quality, and also can be applied to various types of cotton combed mainframe.

With the increasing demand for semi finished products and yarn in cotton textile enterprises, how to meet the requirements of users and improve the quality and quality of products is a systematic project.

Zhejiang Jinfeng should further improve the quality management network, strengthen the quality control points of the production process, and do well in the production.
