Problems solved by technology
Due to the existence of this angle, the distribution of the air volume at the outlet of untwisting air A and the outlet of untwisting air B is uneven, resulting in defects such as unstable untwisting, insufficient untwisting, or even no untwisting on one side
[0005] In the above-mentioned twisting air path, channel i and channel j intersect vertically, resulting in too long air path introduced into the air inlet 15 of the splicing chamber, and the air path is not smooth, resulting in airflow loss and prolonging the time for the airflow to enter the splicing chamber 9 , which directly affects the twisting effect of the yarn

The invention relates to an air twister upper shell stable in untwisting. A twisting chamber, an untwisting air valve chamber, a twisting air valve chamber and air channels communicating the chambers are arranged in the upper shell, wherein the air channels include a channel f for communicating the twisting air valve chamber with the untwisting air valve chamber and a channel g for communicating the untwisting air valve chamber with an untwister, a main air channel and a channel h; and the included angle alpha between the axis of the channel h and the vertical line of the axis of the main channel is 0-3 degrees. In the invention, untwisting air channels are improved according to the theories of the fluid dynamics, the untwisting air flow is reasonably distributed and the yarns are untwisted uniformly and fully; therefore the upper shell meets the untwisting requirements of various yarns.
Description
technical field [0001] The invention relates to an air splicer used in automatic winding machines, doubling machines and two-for-one twisters for splicing yarns and broken ends without joints, in particular to an air splicer upper shell with stable untwisting body. Background technique [0002] The air splicer is an important equipment for producing jointless yarns in the textile industry. It is mainly composed of an air system, an untwisting system and a twisting system. [0003] In the prior art, an air splicer upper housing 5 has a structure such as figure 1 , figure 2 As shown, there are splicing chamber 9, untwisting air valve chamber 17, twisting air valve chamber 18 and air passages communicating with the above-mentioned chambers in the upper housing 5, and the above-mentioned air passages include communicating twisting air valve chambers The e channel and d channel of the chamber 18 and the lower shell, the i channel and the j channel of the communication twistin...
