Abstract
The utility model relates to the technical field of textile machinery, in particular to an alternate deflecting yarn twisting device which is parts using air flow to alternately twist yarns in a forward or reverse direction. The alternate deflecting yarn twisting device comprises a yarn channel, an air flow channel and a vortex cavity, and axis of the yarn channel is perpendicular to the axis of the air flow channel. The vortex cavity is in a cylindrical shape and placed below the yarn channel and a certain distance is arranged between the vortex cavity and the yarn channel, and a plurality of lateral air inlets are formed in the upper end of the vortex cavity. Compressed gas enters the air flow channel and the vortex cavity through a main air-in hole and the lateral air inlets. Intermittent deflecting rotational flow of airflow is formed due to a periodical change of the air inflow of the lateral air inlets and an alternate deflecting twist degree is produced by the yarns under the effect of the rotational flow so that hairiness is decreased, end breakage is reduced, yarn strength is increased and yarn quality is improved.
Description
Technical field
The utility model relates to technical field of textile machine, refers in particular to a kind of alternately break-in yarn false-twisted device.
Background technology
In spinning process, Yarn filoplume is very important problem always, and what of filoplume not only affect the quality and performance of yarn itself, and can affect the afterwards operating efficiency of road process of weaving.Too much filoplume produces the generation of broken end phenomenon easily, and the broken end of splicing can produce cotton knot, affects appearance of fabrics.Yarn filoplume can make adjacent yarn mutually twine, and greatly reduces production efficiency.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of alternately break-in yarn false-twisted device is provided, and reduces the situation of filoplume and broken end.
For achieving the above object, the utility model adopts following technical scheme:
A kind of alternately break-in yarn false-twisted device, a kind of textile machine parts that utilize air stream yarn to be carried out forward and reverse alternating twisting, comprise yarn path, gas channel and vortex cavity, it is characterized in that: the axis of yarn path and the axis of gas channel are perpendicular; Vortex cavity is cylindrical shape, is positioned at the top, yarn path and is separated with a segment distance, and its upper end has several side direction air inlets; Compressed Gas enters gas channel and vortex cavity from primary inlet port and side direction air inlet.
The air inflow cyclically-varying of described side direction air inlet makes air-flow form intermittent break-in eddy flow.
The endoporus of described gas channel is communicated with vortex cavity, and is through to the yarn path.
Described yarn path is semi-enclosed, and air-flow can be discharged from axial joint-cutting.
The number of described side direction air inlet is two to six, is preferably three.
The utility model makes yarn produce the alternately twist of break-in turn by intermittent break-in cyclonic action, has reduced filoplume and broken end, has greatly improved spinning quality.
Description of drawings:
Accompanying drawing 1 is the structural representation of utility model.
The specific embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, hereby lift preferred embodiment and cooperate graphic being described in detail as follows:
See also shown in Figure 1, it is the structural representation of the preferred embodiment of the utility model, the utility model is relevant a kind of alternately break-in yarn false-twisted device, a kind of textile machine parts that utilize air stream yarn to be carried out forward and reverse alternating twisting, comprise yarn path 1, gas channel 2 and vortex cavity 3, the axis of the axis of yarn path 1 and gas channel 2 is perpendicular; Vortex cavity 3 is cylindrical shape, is positioned at 1 top, yarn path and is separated with a segment distance, and its upper end has several side direction air inlets 4; The endoporus of gas channel 2 is communicated with vortex cavity 3, and is through to yarn path 1.
Compressed Gas is from primary inlet port 5 and side direction air inlet 4 injected gas circulation roads, and the air inflow of each side direction air inlet 4 is carried out cyclically-varying, makes air-flow form intermittent break-in eddy flow in vortex cavity 3.Eddy flow is twisted continuously to yarn after entering yarn path 1, makes yarn produce the forward and reverse alternately break-in twist, more axial joint-cutting 6 discharges from the yarn path of air stream.Yarn replaces break-in twisting and effectively reduces the filoplume rate, has improved yarn qualities.
Certainly, more than be the utility model preferred embodiments only, be not to limit the scope of application of the present utility model with this, so, allly make equivalent change in the utility model principle and all should be included in the protection domain of the present utility model.
