How the conventional continuous yarn two-for-one twister of low price is transformed into the staple fibre yarn two-for-one twister that cladded yarn is suitable for and just becomes the anxious technical issues that need to address in present technique field.
Summary of the invention
The purpose of this invention is to provide a kind of improved continuous yarn two-for-one twister, make it to be applicable to staple fibre yarn twisting.
Above-mentioned purpose of the present invention reaches by the following technical programs:
A kind of improved continuous yarn two-for-one twister is characterized in that: install the back yarn dish on the tensioner of described continuous yarn two-for-one twister additional; Change the taper twisting dish of former continuous yarn two-for-one twister spindle arrangement bottom the dish-type twisting dish of short fiber two-for-one twister into, and all smooth column type thin-walled cage ring of surfaces externally and internally is installed thereon; Described back yarn dish is provided with thread guide eyelet.
A kind of optimal technical scheme is characterized in that: described back yarn dish comprises: the disk that the centre of arc, taper or a plane is with holes, and the diameter in hole and the external diameter of tensioner are complementary, and can rotate flexibly; This disk external diameter is greater than the maximum gauge of yarn package to be twisted; Described thread guide eyelet is equipped with the pass thread-carrier.
The improved continuous yarn two-for-one twister that the present invention proposes has following advantage:
Owing to adopt the enterprise of polyester-cotton blend cladded yarn production uniform underlinen fabric mostly to be the chemical fibre weaving mill, so continuous yarn two-for-one twister that utilizes the chemical fibre weaving mill to have in a large number and generally use, simply transform according to the characteristics of cladded yarn and to make it to meet the requirements, the continuous yarn two-for-one twister floor space that then has small investment, double-deck sided configuration is few, two-for-one twister can change core devices flexibly and realize the general purpose of long filament/staple fibre yarn.And, the doubling twisting of cladded yarn single thread to be transferred to the weaving mill carry out, the working depth of extensible weaving mill overcomes the too high problem of the expense of twisting thread that causes because of the cotton mill twisting apparatus is few.
The present invention proposes the new technology of transforming, the conventional continuous yarn two-for-one twister of low price being transformed into the suitable staple fibre yarn two-for-one twister of cladded yarn through simple.And when not needing to process cladded yarn or other staple fibre yarns, can get back to original configuration immediately, be applied to the twisting of long filament smoothly.
The speed of service of the two-for-one twister through transforming can be near continuous yarn two-for-one twister, and is faster more than 20% than the speed of service of short fiber two-for-one twister, improved production efficiency.Wrap bale of cotton heart yarn strand by above-mentioned through transforming washing of continuous yarn two-for-one twister processing, the twist uniformity is suitable with traditional short fiber two-for-one twister product, can satisfy the performance requirement of strand.
Made full use of the continuous yarn two-for-one twister of chemical fibre weaving mill common configuration, and transformed easy; When needs are applied to two-for-one twister long filament twisting again, can change original assembly, original function can recover; Improvement expenses is low.The characteristics of the double-deck many ingots of bilateral of continuous yarn two-for-one twister position have been utilized, the floor space that can save two-for-one twister in a large number.
The present invention will be further described below by the drawings and specific embodiments, but and do not mean that limiting the scope of the invention.
Description of drawings
Fig. 1 is the tension analysis figure of continuous yarn two-for-one twister commonly used.
Fig. 2 is the structural representation of the improved continuous yarn two-for-one twister of the present invention.
The specific embodiment
As shown in Figure 1, for using the tension analysis figure of continuous yarn two-for-one twister always.Yarn is in the influence of unwinding point 1 to the size of the yarn package to be twisted of the tension force (being called unwinding tension) in tensioner head end 2 this section strokes, mantle friction degree, ingot speed.Contain the reason of the yarn of staple fibre in unwinding section and the friction of yarn body because of cladded yarn etc., the unwinding tension of unwinding tension during much larger than the long filament double twisting, thus the travel path that isolated plant changes yarn need be set, to reduce rubbing action, to reduce and break end; Staple fibre yarn and cladded yarn at tensioner head end 2 to the tension force (drawing tension force) between the storage yarn dish yarn outlet 3, should be less than the drawing tension force of long filament, and will guarantee that the path is smooth; The tension force (balloon tension) that produces when yarn moves with major diameter in the periphery when outside air ring and inboard unwinding yarn clash, very easily produces and breaks end especially with the influence of ingot speed, yarn count, air ring twizzle height.Therefore, special-purpose device need be set avoid air ring to be subjected to unexpected the obstruction, to guarantee carrying out smoothly of cladded yarn double twisting.
As shown in Figure 2, be the structural representation of the improved continuous yarn two-for-one twister of the present invention.To two 60s cladded yarn single thread plying and be wound into and twist with the fingers package, be inserted in the middle of the two-for-one twisting spindles, the top of dish-type twisting dish 5 with doubling frame.And sth. made by twisting package top insertion tensioner 1, tensioner 1 is by reequiping, applied the tensioner of back yarn dish 2.The back yarn dish adopts stalloy to be stamped to form, and has 6 thread guide eyelets 3 symmetrically and the pass thread-carrier is installed.For the bifilar cladded yarn of 60s, pass from outermost thread guide eyelet 3, suitable for reading to tensioner; From through the pressurization pellet shot from a slingshot in the middle of the tensioner, derive again, guide to the coiler device of top along slim cage ring 4 outsides to the thread guide eyelet of dish-type twisting dish below.The coiler device of the strand after the twisting still adopts the coiler device of former continuous yarn two-for-one twister.Other operations are also constant substantially.Adopt improved continuous yarn two-for-one twister as shown in Figure 2, two-for-one twister can turn round with the speed that per minute 9000 changes, and cladded yarn strand quality is good.
