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 with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0019] like figure 1 , figure 2 , image 3 As shown, a kind of yarn wheel type wrapping yarn supplying trachea comprises 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 the compression section 4 and the expansion section of the flared opening 8. In the middle is the throat section 6 with a smaller cross-sectional radius. The branch pipe 10 is inclined to the compression section 4 and is in sealing communication with 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 the acute an...

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 double-ply yarn distribution device for wrapping yarn, in particular to a yarn wheel-type wrapping yarn supplying air tube. Background technique [0002] The wrapped yarn is a yarn structure formed by one or more yarns as the core wire, and another or more yarns spirally wrapped around the outer circumference of the core yarn. Usually the core yarn is spandex, and the outer yarn is short fiber 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 the effect of different lengths. In the prior art, the core yarn and the outer yarn achieve the effect of different lengths through different passive unwinding speeds of the yarns. This method may cause yarn breakage or the length effect cannot meet the requirements and other phenomena. At the same time, the pas...
