The Breakthrough Development of Key Technology of Weaving Machine ——Weft Insertion
Jul 16, 2018

Various practical needle looms began to appear internationally in the 1950s. For more than half a century, the automatic weaving looms have also been widely used due to the extensive application of electronic information technology, showing the obvious advantages in quality, variety and production efficiency, and quickly replaced the shuttle looms. Mechatronics technology has enabled the production automation of narrow looms to reach a high level, which plays an important role in improving the speed and production efficiency of looms, expanding varieties and improving product quality.

The tape making machine is the development direction of the world loom, and the development of the technological revolution

The narrow fabric weaving loom can best meet the development trend of the weaving process, so the shuttleless loom is the development direction of the world loom. From the development trend of shuttleless looms, breakthroughs have been made in key technologies and links, such as:

Weft insertion: There have been many improvements in jet weft insertion in the past 10 years, such as one main nozzle fixed on the frame and the other main nozzle fixed.

It is fixed on the sley and swings together with the sley, and there is also a pull nozzle that adds a suction nozzle at the exit end of the weft. In recent years, the computer has been used to control electricity.

The magnetic valve is opened and closed, and the solenoid valve is changed from controlling four auxiliary nozzles to controlling two auxiliary nozzles. The number of solenoid valves is almost

Doubled, but the gas consumption is very obvious. Of course, there are still air jet loom that insist on using a solenoid valve to control four.

Auxiliary nozzle. It is considered that the most ideal method is to control one auxiliary nozzle by a solenoid valve, and the distance between the auxiliary nozzles is suitable. When it is increased, it may be more obvious to save energy.
