Problems solved by technology

[0004] In order to overcome the shortcomings of unstable, uneven and insufficient yarn untwisting existing in the existing rotating air untwisting mechanism, and meet the requirements for processing high-quality knot-free yarns, the purpose of the present invention is to design a swirling air untwisting air The metal untwisting tube is used for the splicer, and the air path of the untwisting mechanism is properly improved to improve the knot forming rate and production efficiency

Embodiment Construction

[0010] As shown in Figure 1: the untwisting tube used in the swirl untwisting air splicer is basically the same in appearance as the untwisting tube used in the past. The inside of the untwisting tube 2 is a central through hole 8, which constitutes an untwisting chamber, and the upper part of the untwisting tube 2 is evenly distributed along the circumferential direction with 1 to 3 same eccentric directions opposite to the twist direction of the yarn and thread. The air injection hole 6 is inclined downward, and the air path leading to the untwisting mechanism is shortened. The high-speed airflow in the air flow chamber 4 passes through the air injection hole 6 on the untwisting pipe 2, and is sprayed into the central through hole 8 of the untwisting pipe 2, forming a direction The swirling flow of the downward movement sucks the yarn and thread tail into the central through hole 8 to realize uniform untwisting.

Abstract

This invention relates to fittings of spinnnig machine, especially a metal detwisting tube of the eddy flow detwisting air splice machine. The center of the detwisting tube is axial interpenetrate with the central through hole. On the top we set a fumarole along the circumferential direction and it is reverse to the direction of the yarn twist, and the eccentric is downward sloping. The detwisting tubes are fixed on the both sides of the epitract. Among the outside wall of circle of the detwistnig tube and the inside wall of the epitract and the fumarole onduit, there will form the fan flow hole, the fan flow hole is connected with central through hole by fumarole. There are joint rings on both top and bottmo of the fan flow hole. The detwisting tube has simple structure, and the design is reasonable. The age limit will be long and the performance is aviable, and easy to use and maintain.

Description

technical field [0001] The invention relates to a spinning machine accessory, in particular to a metal untwisting tube for a swirl untwisting air splicer. Background technique [0002] The air splicer for textile is an important equipment for the textile industry to produce knot-free yarn. The swirling untwisting air splicer is mainly composed of air system, swirling untwisting system and twisting system. [0003] In the prior art, the rotating air flow untwisting mechanism mainly adopts a metal untwisting tube with a central through hole, and an eccentric and downwardly inclined air jet hole opposite to the twist direction of the yarn is set on the upper part of the untwisting tube. It rotates at a high speed in the through hole in the center of the untwisting tube, so that the yarn and thread tail are sucked by the swirling flow to realize untwisting. The loss and untwisting tube adopts a single small air jet hole, which causes the defects of unstable, uneven and insuffi...
