The difference between tray type and bobbin type automatic winder.

Zhang Zixiang, the inventor of the patent for yarn storage device of automatic winder, introduced the technical achievement of the patent for yarn storage device of automatic winder. On the basis of ensuring quality and efficiency, the imported automatic winder is equipped with a patented yarn saving device, which can save 1- 1.5 tons a year (taking 18.2 as an example), and the enterprise can increase its income by about 30,000 yuan a year.

Wuhan Qinghong Electronic Equipment Factory is entrusted by Zhang Zixiang, the patent inventor, as an importer (West Germany Murata 7-2.

Popularization and application of patented technology of yarn storage device of automatic winder.

This patented technology is convenient to install and use, safe and reliable, does not flush welding equipment, does not affect workers' operation, and has obvious saving effect.

How to reduce consumption and increase income is one of the goals pursued by today's manufacturers. Although the imported winder has good quality and high efficiency, it is well known that its disadvantage is that it wastes a lot of silk. If this patented technology of yarn saving device is installed, consumption can be greatly reduced, yarn can be saved and efficiency can be improved.

From the practice of dozens of domestic enterprises promoting this patented technology, the effect is remarkable and it is the most effective way to save yarn.

Here is a brief introduction to the patented technical achievements of the yarn-saving device: yarn-saving principle: As we all know, the imported winder produces too much yarn return, which is also a problem that manufacturers who introduce this equipment often discuss and need to solve urgently.

Many years' practice in Zhang Zixiang has found that a large number of yarn rejections from imported winder are mainly caused by the long yarn sucked by each suction port during head changing, splicing and head finding.

Zhang Zixiang invented this patent to save money by reducing the yarn length at the air inlet.

Murata 7-2 machine and West Germany 238 machine are introduced respectively: For Murata 7-2 machine, the waste of yarn returning is mainly on the suction nozzle. When the machine is automatically connected, when the upper suction nozzle is close to the pagoda bobbin, the grooved drum drives the pagoda bobbin to reverse and unwind the yarn, and the yarn is sucked into the upper suction nozzle. Due to the rapid reversal of the pagoda bobbin, the yarn unwinding time is too long, which leads to waste.

The patent reduces the reverse speed of the groove and the length of the air inlet of the upper suction head to reduce the amount of silk return. Generally, the normal suction length is 3.8 meters, and the effect is remarkable if it is changed to 1.8 meters.

For the model 238 machine in West Germany, the waste of rewinding is mainly in the lower suction nozzle.
