Problems solved by technology
In the prior art, the core yarn and the outer yarn achieve the effects of different lengths through different yarn passive unwinding speeds. This method will cause yarn breakage or the length effect cannot meet the requirements. At the same time, the passive unwinding method The production speed is greatly restricted, and the yarn passing through the guide wheel is also vulnerable to damage during unwinding

Embodiment Construction
[0018] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.
[0019] Such as figure 1 , figure 2 , image 3 As shown, a yarn wheel wrapping yarn supply air tube includes a Venturi tube 2 and a branch tube 10 sealingly connected with the Venturi tube 2, and the two ends of the Venturi tube 2 are a compression section 4 and an expansion section with trumpet-shaped openings 8. In the middle is the throat section 6 with a small cross-sectional radius. The branch pipe 10 is obliquely connected to the compression section 4 and the throat section 6. The angle between the axis of the branch pipe 10 and the axis of the throat section 6 is an acute angle, preferably 15°-90°. , the airflow in the branch pipe 10...

The invention relates to a yarn wheel type yarn feeding air tube for wrapped yarns. The yarn wheel type yarn feeding air tube for the wrapped yarns comprises a Venturi tube, a branch tube and a yarn wheel arranged at the communication part of the Venturi tube and the branch tube. The yarn wheel type yarn feeding air tube for the wrapped yarns is characterized in that the Venturi tube is provided with a compression section, a throat tube section and an expansion section which are coaxial, the branch tube is communicated with the throat tube section in a sealing mode, and the included angle between the axis of the branch tube and the axis of the compression section is an acute angle. The yarn wheel type yarn feeding air tube for the wrapped yarns overcomes defects in the prior art, the Venturi tube is adopted to be matched with the branch tube with the yarn wheel, the breakthrough mode of air flow driving is adopted to unreel the yarns, damage to the yarns and the phenomenon of broken yarns and the like can be avoided due to the fact that the air flow driving is relatively gentle, and the friction force which is generated at the yarn turning corner when the moving direction of the yarns is changed can be improved and reduced through the yarn wheel.
Description
technical field [0001] The invention relates to a wrapping yarn double-ply yarn distribution device, in particular to a yarn wheel type wrapping yarn supplying air tube. Background technique [0002] Wrapped yarn is a yarn structure in which one or more yarns are used as the core, and another or more yarns are spirally wrapped around the outer circumference of the core. Usually the core yarn is spandex, and the outer yarn is spun yarn. . During production, the feeding speed of the core yarn and the outer yarn is different, the feeding speed of the core yarn is relatively small, and the feeding speed of the outer yarn is relatively large, resulting in different lengths of effect. In the prior art, the core yarn and the outer yarn achieve the effect of different lengths through different yarn passive unwinding speeds. This method will cause yarn breakage or the length effect cannot meet the requirements. At the same time, the passive unwinding method The production speed is ...
