Abstract

The utility model discloses a kind of duplex rings, this compound steel collar is welded by upper rings and lower rings, upper diameter of ring is large, lower diameter of ring is little, first when changing spinning count and uprising count yarn by middle coarse yarn line without the need to again changing rings, can be used alone rings or be used alone lower rings, improve spinning efficiency; Secondly, also can use by rings up and down simultaneously, yarn is each passed through the steel traveler on lower rings and upper rings, in spinning process due under diameter of ring ratio diameter of ring large, so Yarn twisting hysteresis can be produced at upper rings place during Yarn twisting, rings is not twisted completely to during the Yarn twisting of twist triangle zone part, do not reach original number of twists, reduce yarn moment of torsion, and twisting has been continued from upper rings to lower rings yarn, thus achieve substep twisting, improve yarn quality.

Description

A kind of duplex rings
Technical field
The utility model relates to spinning new technical field, specifically a kind of duplex rings.
Background technology
In ring spinning process, the twisting of yarn is completed by rings and steel traveler jointly with winding, and this is one of ring spinning frame main feature.In spinning process, the twisting realized yarn that cooperatively interacts of rings and steel traveler is shaped, and its effect quality directly has influence on yarn quality and production efficiency.On general fine spining machine, rings all adopts individual layer track structure, and its twisting process is completed to twist triangle zone one step by steel traveler, often makes yarn strength too high, and yarn moment of torsion is excessive, affects yarn quality.Meanwhile, needing again again to change rings from spinning when middle coarse yarn changes high-count yarn spun, affecting spinning efficiency.
For this, the utility model designs a kind of duplex rings, this compound steel collar is welded by upper rings and lower rings, upper diameter of ring is large, lower diameter of ring is little, first when changing spinning count and uprising count yarn by middle coarse yarn line without the need to again changing rings, can be used alone rings or be used alone lower rings, improve spinning efficiency.Secondly, also can use by rings up and down simultaneously, yarn is each passed through the steel traveler on lower rings and upper rings, in spinning process due under diameter of ring ratio diameter of ring large, so Yarn twisting hysteresis can be produced at upper rings place during Yarn twisting, rings is not twisted completely to during the Yarn twisting of twist triangle zone part, do not reach original number of twists, reduce yarn moment of torsion, and twisting has been continued from upper rings to lower rings yarn, thus achieve substep twisting, improve yarn quality.
Summary of the invention
The purpose of this utility model is a kind of duplex rings of design, by upper rings and lower rings, achieve and become substep twisting mode from original step mode of twisting, reduce yarn moment of torsion, improve yarn quality, also can be used alone upper rings or lower rings simultaneously, make spin uprise count yarn by middle coarse yarn line time without the need to again changing rings, improve spinning efficiency.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of duplex rings, comprise rings and lower rings, be welded and fixed by three metal bars between described upper rings and lower rings, the center of circle of described upper rings and lower rings on the same line, the plane at described upper rings and lower rings place is parallel to each other, described upper rings race way diameter is between 40mm-50mm, described lower rings race way diameter is between 35mm-45mm, and between described upper rings and lower rings, interplanar spacing is between 2mm-30mm.
In spinning process, rings of the present utility model is fixed on ring rail, upper rings and lower rings install steel traveler additional respectively.When spinning, yarn realizes substep twisting respectively through two steel travelers, reduces yarn moment of torsion, improves yarn quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model duplex rings
Wherein 1 is upper rings, and 2 is lower rings, and 3 is the steel traveler of upper rings, and 4 is the steel traveler of lower rings, and 5 is metal bar.
Detailed description of the invention
As shown in Figure 1, a kind of duplex rings, comprise rings 1 and lower rings 2, be welded and fixed by three metal bars 5 between upper rings 1 and lower rings 2, the center of circle of upper rings 1 and lower rings 2 on the same line, the plane at upper rings 1 and lower rings 2 place is parallel to each other, upper rings 1 race way diameter is between 40mm-50mm, lower rings 2 race way diameter is between 35mm-45mm, between upper rings 1 and lower rings 2, interplanar spacing is between 2mm-30mm, and upper rings 1 and lower rings 2 install steel traveler 3 and steel traveler 4 respectively.
During use, first duplex steel collar base is fixed on ring rail, during spinning, yarn will be drawn first by the steel traveler 4 on lower rings 2 in spool, the steel traveler 3 upper rings 1 is passed through again from inside, finally be connected with the yarn at front jaw place, in spinning process, two steel travelers all rotate along rings, because upper rings 1 diameter is bigger than normal than lower rings 2 diameter, so Yarn twisting hysteresis can be produced at upper rings place during Yarn twisting, rings 1 is not twisted completely to during the Yarn twisting of twist triangle zone part, do not reach original number of twists, reduce yarn moment of torsion, and twisting has been continued from upper rings 1 to lower rings 2 yarn, thus achieve substep twisting, finally make reel for yarn around on spool.
