Made by twisting that can reduce the twizzle through the arc twizzle time falls into the effect.

Description

A kind of arc yarn guiding hook device

Technical field

The utility model relates to new technical field of spinning, a kind of arc yarn guiding hook device.

Background technology

All the time, RING SPINNING gains great popularity with its wide adaptability to raw material and higher yarn quality.But front during frame spinning twist Roller nip forms twist triangle zone.In twist triangle zone, owing to the stress of yarn inside and outside layer fiber is different, make the fiber in twist triangle zone Shift repeatedly, cause fiber two ends and be often exposed to outer formation filoplume；Tension force suffered by the outside fiber of twist triangle zone is maximum, suffered by inner fabric Tension force is minimum so that in the yarn after twisting, the pretension suffered by fiber is inconsistent, and the strength causing whole yarn is strong less than all single fibers in cross section Power sum；Fiber produces stretcher strain after twisting, there is residual torque in yarn, causes yarn twist unstable, is unfavorable for that rear road processes. Therefore, in the last few years, the transformation for RING SPINNING existed especially about aspects such as filoplume, raising ultimate strength, reduction residual torque are greatly reduced Achieve a series of great achievement in theory and practice, be the most of paramount importance one by installing false-twisting device additional at spinning section, The Hong Kong Polytechnic University It is the most typically to represent that professors Tao Xiaoming etc. turn round appropriate spinning.Its utilize scroll tube produce send out false twisting, affect twist triangle zone fiber Power is distributed, thus improves fiber arrangement in the yarn and form, reduces the internal stress in yarn, reaches the effect of stable yarn twist.

Twizzle is a turning point in ring spinning frame spinning process, transmission, control the spinning stability of air ring, the minimizing to the sliver twist Fuzzy yarn and broken end are most important.Front roller claims spinning section to the yarn section between twizzle, and the strength that it is had claims spinning strength, and spinning is strong Power largely acts on twizzle.Therefore, actual spinning process requiring, twizzle should have wear-resisting, smooth, between yarn and twizzle Coefficient of friction is the least, to reduce the sunken effect of the sth. made by twisting of yarn.

For this, the utility model provides a kind of arc yarn guiding hook device, during spinning, through the yarn of draw twisting through the groove of twizzle extrados Afterwards by bead winding on spool so that in twist transmittance process from bottom to top, fall into effect at the sth. made by twisting that can reduce twizzle through arc twizzle Should.

Summary of the invention

The purpose of this utility model is to provide a kind of can reduction to twist with the fingers the arc yarn guiding hook device falling into effect.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of arc yarn guiding hook device, including twizzle, described twizzle is Arcuate structure, the radian of described twizzle is between π/4 to π/3, and the arc length of described twizzle is between 30-50mm, along described guide Having groove structure on the extrados of hook, the middle part of the intrados of described twizzle is connected with being connected support, and described connection support is fixed on spun yarn On locomotive table top, the angle in described connection support and spinning frame ride face is between 30-45 °.

During use, first arc twizzle is fixed on spinning frame ride face by connecting support, during spinning, through the yarn of draw twisting through leading After the groove structure of yarn hook extrados by bead winding on spool so that in twist transmittance process from bottom to top, through arc twizzle The sth. made by twisting that can reduce twizzle falls into effect.

The beneficial effects of the utility model are: have globoidal structure by employing one and cambered surface includes reeded twizzle, to reduce twizzle Twist with the fingers and fall into effect, improve yarn quality, especially improve yarn strength, reduce broken end.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

Detailed description of the invention

A kind of arc yarn guiding hook device, including twizzle 1, twizzle 1 is arcuate structure, and the radian of twizzle 1 arrives between π/3 in π/4, The arc length of twizzle 1, between 30-50mm, has groove structure 2, the centre of the intrados of twizzle 1 on the extrados along twizzle 1 Position is connected with being connected support 3, connects support 3 and is fixed on spinning frame ride face, connects the support 3 angle with spinning frame ride face at 30-45 ° Between.

During use, first arc twizzle is fixed on spinning frame ride face by connecting support 3, during spinning, passes through the yarn of draw twisting After the groove structure 2 of twizzle 1 extrados by bead winding on spool so that in twist transmittance process from bottom to top, leading through arc The sth. made by twisting that can reduce twizzle during yarn hook falls into effect.
