Abstract
This invention relates to fittings of spinnnig machine, especially a metal detwisting tube of the eddy flow detwisting air splice machine. The center of the detwisting tube is axial interpenetrate with the central through hole. On the top we set a fumarole along the circumferential direction and it is reverse to the direction of the yarn twist, and the eccentric is downward sloping. The detwisting tubes are fixed on the both sides of the epitract. Among the outside wall of circle of the detwistnig tube and the inside wall of the epitract and the fumarole onduit, there will form the fan flow hole, the fan flow hole is connected with central through hole by fumarole. There are joint rings on both top and bottmo of the fan flow hole. The detwisting tube has simple structure, and the design is reasonable. The age limit will be long and the performance is aviable, and easy to use and maintain.
Description
Technical field
The present invention relates to workshops accessory, especially a kind of metal back-twist tube that is used for eddy flow untwisting air splicer.
Background technology
Weaving is the important equipment of the knotless yarn of caused by spinning industrial production with air splicer.Eddy flow untwisting air splicer mainly is made of air-channel system, eddy flow untwisting system and twist system.
In the prior art, swirling eddy untwisting mechanism mainly adopts the metal back-twist tube of central through hole, back-twist tube top is offered one and is twisted with the fingers to opposite eccentric downward-sloping fumarole with yarn, the air-flow that is sprayed into by fumarole rotates at a high speed in the back-twist tube central through hole, yarn, line tail are sucked and realize untwisting by eddy flow like this, but it is long that this untwisting mechanism exists the gas circuit of introducing untwisting mechanism, the air-flow that sprays into back-twist tube exists loss and back-twist tube to adopt single little fumarole, thereby causes yarn untwisting instability, inhomogeneous, inadequate defective.
Summary of the invention
There are yarn untwisting instability, inhomogeneous, inadequate deficiency in order to overcome existing swirling eddy untwisting mechanism, satisfy the requirement of the high-quality knotless yarn of processing, the objective of the invention is to design a kind of eddy flow untwisting air splicer metal back-twist tube, and to the suitably improvement of untwisting mechanism gas circuit do, to improve into knot rate and production efficiency.
According to technical scheme provided by the present invention, the center of back-twist tube is the central through hole that connects vertically, and top along the circumferential direction is provided with yarn and twists with the fingers to opposite eccentric downward-sloping fumarole.
Back-twist tube is arranged symmetrically in the left and right sides of upper shell, constitutes air flow chamber between the inner peripheral wall of the outer circle wall on back-twist tube top and upper shell and jet pipe, and fumarole is linked up air flow chamber and central through hole.Fumarole has 1～3 of even layout.Upper and lower part in air flow chamber is furnished with sealing ring.The gas channel that is communicated with jet pipe is set in upper shell.
The invention has the beneficial effects as follows: according to fluid dynamic theory, designed rotation untwisting air splicer back-twist tube, made yarn, line tail in the untwisting chamber, realize even untwisting, adapted to the untwisting requirement of different cultivars yarn.Back-twist tube of the present invention adopts metal material to make, reasonable in design, and long service life, the yarn untwisting is stable, even, reliable.
Description of drawings
Fig. 1 is the structure chart of eddy flow untwisting air splicer with back-twist tube.
Fig. 2 is the untwisting mechanism matching chart in back-twist tube and the air splicer upper shell.
The specific embodiment
Shown in Figure 1: eddy flow untwisting air splicer is basic identical in shape with used in the past back-twist tube with back-twist tube.The inside of this back-twist tube 2 is central through hole 8, this central through hole 8 constitutes the untwisting chamber, along the circumferential direction uniform 1～3 identical the twisting with the fingers to opposite eccentric downward-sloping fumarole 6 in the top of back-twist tube 2 with yarn, line, and shorten the gas circuit of leading to untwisting mechanism, high velocity air in the air flow chamber 4 in the central through hole 8 of spirt back-twist tube 2, forms the eddy flow that moves downward by the fumarole 6 on the back-twist tube 2, yarn, line tail are sucked in the central through hole 8, realize even untwisting.
Shown in Figure 2: the untwisting mechanism in the upper shell 1 of back-twist tube 2 and air splicer cooperates.This untwisting mechanism is made by metal material, be symmetric arrangement in upper shell 1 and arranged on left and right sides, between the inner peripheral wall of the outer circle wall on back-twist tube 2 tops and upper shell 1 and jet pipe 5, constitute air flow chamber 4, the upper and lower part of air flow chamber 4 is furnished with sealing ring 3, gas path layout is made of gas channel 7, fumarole 6, jet pipe 5, air flow chamber 4, total design, layout advantages of simple.
