Description
Technical field
The utility model relates to a kind of hand air splicer that the caused by spinning industrial production Yarn break connects that is used for, and especially a kind of bobbin winder, doubling frame and two-for-one twister of being applicable to is to yarn, the knotless eddy flow untwisting air splicer of splicing of line broken end.
Background technology
Weaving is the important equipment of the knotless yarn of caused by spinning industrial production with air splicer.Air splicer mainly is made of air-channel system, untwisting system, twist system.
In the prior art, the untwisting system mainly contains two classes: a class is to adopt oscillator, and promptly by a nozzle, an inner chamber is plastics back-twist tube and oscillating rubber sheet formation that places in the back-twist tube inner chamber of rectangular body cavity groove.Its operation principle is that air-flow is blown into yarn, line tail in the untwisting tube chamber, under action of high-speed airflow, the higher-order of oscillation that oscillator plate produces, make yarn realize untwisting, but it is easily aging that this untwisting form exists the oscillating rubber sheet, and the plastics back-twist tube is easy to crack, and service life is short, change frequently the maintenance defect of high cost.Though another kind of employing metal back-twist tube, and utilization makes the yarn untwisting with the yarn sth. made by twisting to opposite air-flow, but it is long to exist the gas circuit of introducing back-twist tube, and it is unreasonable etc. directly air-flow to be blown into back-twist tube, windage loss, back-twist tube structural design, causes untwisting instability, inadequate defective.
Summary of the invention
In order to overcome the deficiency of existing air splicer, the utility model provides the eddy flow untwisting air splicer of a kind of more reasonable structure, more reliable performance, this air splicer is primarily aimed at untwisting system gas circuit, untwisting air flow chamber, back-twist tube and has carried out brand-new design, improve product stability in use and reliability, enlarge the scope of application, increase the service life easy to use and reduction maintenance cost.
According to design provided by the utility model, eddy flow untwisting air splicer comprises a upper shell that case is housed, be equipped with on the upper shell and cut yarn and yarn clamping mechanism, and the splicing cavity of a band gag, middle shell at upper shell bottom connecting band cylinder, middle shell middle part one side is equipped with a manual plate machine, the middle shell bottom connects the lower house that a side has intake interface, it is characterized in that: in upper shell, be provided with swirling eddy untwisting mechanism, in swirling eddy untwisting mechanism, 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 and arranged on 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.Is furnished with sealing ring at back-twist tube that forms air flow chamber and the upper and lower part between upper shell.The gas channel that is communicated with jet pipe is set in upper shell.
The beneficial effects of the utility model are: according to fluid dynamic theory, invented swirling eddy untwisting technology, and made the yarn untwisting evenly, fully by producing the Rotating with Uniform air-flow in the untwisting chamber of back-twist tube, adapted to the untwisting requirement of different cultivars yarn.The utility model untwisting apparatus is made by metal material, and is simple in structure, reasonable in design, and long service life, stable performance, reliable, and easy to use, reduce the maintenance cost.

The specific embodiment
As shown in the figure: the utility model was with traditional used air splicer was basic identical in shape in the past, mainly finish yarn clipping by air-flow by one, cut yarn, the splice air splicer upper shell 4 of action such as broken yarn of swirling eddy untwisting and twisting, an and cylinder body formation that power can be provided and distribute each gas circuit of control that is positioned at upper shell 4 bottoms and is attached thereto, in the upper shell 4 of eddy flow untwisting air splicer, designed swirling eddy untwisting mechanism, at the middle shell 6 that links to each other with upper shell 4, designed gas circuit in the lower house 7, and shortened the gas circuit of leading to untwisting mechanism by the pneumatic circuit layout.Swirling eddy untwisting mechanism comprises that the both sides upper design has the jet pipe 12 of symmetry, the back-twist tube 9 of the band central through hole 15 of bilateral symmetry channel arrangement, the air flow chamber 11 that forms between endoporus that is provided with on back-twist tube 9 top outer circle walls and the upper shell 4 and the jet pipe 12, uniform some identical the twisting with the fingers to opposite eccentric downward-sloping fumarole 13 in the top of the back-twist tube 9 of band central through hole 15 with yarn.The gas channel 14 that is communicated with jet pipe 12 is set in upper shell 4.
Case 5 is installed outside upper shell 4, with the various structures that are provided with on the protection upper shell 4, designed swirling eddy untwisting mechanism on the upper shell 4, a back-twist tube 9 is mainly contained in this mechanism, in back-twist tube 9, be provided with the untwisting chamber 1 that mainly forms by central through hole 15, jet pipe 12 and endoporus as a part of swirling eddy untwisting mechanism are set, formation air flow chamber 11 between jet pipe 12 and back-twist tube 9 top outer circle walls on upper shell 4; Be equipped with to the yarn fixed length, locate and finish cut the yarn effect cut yarn and yarn clamping mechanism, and splicing cavity 2 of broken yarn being twisted into the band gag of an one thread.Middle shell 6 at upper shell 4 bottom connecting band cylinders, to distribute and to control the cylinder body of each gas circuit, middle shell 6 middle parts one side is equipped with a manual plate machine 3 that is used to open and close air-flow, moving once as plate, can finish once the action of all structures, middle shell 6 bottoms connect the lower house 7 that a side has intake interface 8, so that be connected with the tracheae that air-flow power is provided.
The structure of the swirling eddy untwisting mechanism arrangement in the air splicer upper shell 4.Adopted advanced swirling eddy untwisting technology in the utility model, it was with plastics oscillator and the swirling eddy back-twist tube that the oscillating rubber sheet is set commonly used was different in the past, and this untwisting mechanism makes by metal material; Swirling eddy untwisting mechanism in the utility model by the back-twist tube 9 that has central through hole 15, jet pipe 12, and upper shell 4 on the air flow chamber 11 that constitutes between the endoporus, jet pipe 12 and the back-twist tube 9 top outer circle walls that are provided with, the sealing ring 10 that is arranged at air flow chamber 11 upper and lower parts is formed, the untwisting chamber 1 that central through hole 15 wherein forms.This untwisting mechanism is symmetric arrangement in the left and right sides of upper shell 4.The top of the back-twist tube 9 of band central through hole 15 is uniform some identical, the eccentric downward-sloping fumarole 13 opposite with the yarn twist direction, during work, air-flow is in jet pipe 12 enters the air flow chamber 11 of annular, the fumarole 13 spirt untwisting chambeies 1 that high velocity air in the air flow chamber 11 tilts by back-twist tube 9, form the air-flow of rotation at a high speed, flow out downwards in the untwisting chamber 1 that is formed by central through hole 15 by back-twist tube 9, what move downward twists with the fingers to opposite swirling eddy yarn with yarn, the line tail sucks the untwisting chamber 1 that is formed by central through hole 15, in untwisting chamber 1, carry out untwisting, form cotton-shaped, yarn, after the line tail is finished untwisting, be introduced into twist system twisting, in the twisting chamber, broken yarn connected into an one thread.Reach the untwisting purpose, for next step twisting is got ready.
