Description
Technical field
The present invention relates to the spiral-flow detwisting air twist splicer in textile machine, specifically a kind of eddy flow untwisting device of twisting with the fingers specialty yarn for S.
Background technology
Air splicer is the weight equipment of producing non junction yarn in textile industry, and air splicer is mainly comprised of air-channel system, untwisting system, twist system.Traditional ring spinning method, yarn has that strong or weak S twists with the fingers or Z twists with the fingers, in order to make these yarns can obtain good untwisting, act on yarn end the air-flow ejecting must and self the twisting with the fingers on the contrary of described yarn.
Untwisting device is arranged on the upper shell of air splicer, and Yarn splicing is anticipated.Untwisting has polytype, and conventional a kind of body of being done by engineering plastics and oscillating rubber sheet form.Due to compressed-air actuated effect, oscillating rubber sheet is patted repeatedly, make the fiber that sucks untwisting device obtain untwisting.Its shortcoming oscillating rubber sheet easily comes off and is aging, directly affects the outward appearance of the untwisting stability of yarn and the tieing of splicing, and has increased the input of cost, has reduced service life; The body that another kind is done by engineering plastics and little copper blowpipe form, need to be by assembling and regulating the angle of copper blowpipe to reach its best untwisting effect.Because body is engineering plastics, in use want regular inspection and replacing, because the body of working of plastics self intensity is low, yielding and not wear-resisting.Due to the continuous action of yarn end, the yarn inlet of untwisting device can produce pit in addition, obvious to the untwisting influential effect of yarn, does not reach the object of expection, for those, have a rigidity or high-twist yarn problem especially serious.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of eddy flow untwisting device of twisting with the fingers specialty yarn for S is provided, this untwisting device long service life, untwisting is effective.
According to technical scheme of the present invention: a kind of eddy flow untwisting device of twisting with the fingers specialty yarn for S, comprise body, on described body, be furnished with the untwisting hole h of level, described body is metal material, on described body, be provided with the charging groove of the untwisting fiber inner crossing with described untwisting hole h, in described body, be furnished with the e passage, f passage and the spray-hole g that are interconnected from bottom to top, described spray-hole g and described untwisting hole h are arranged in the both sides of described charging groove; Described spray-hole g is horizontally disposed, between the extended line of its center line and the center line of described untwisting hole h, forms sharp angle α, and the diameter of described spray-hole g is less than the diameter of described untwisting hole h and the top that described spray-hole g is inscribed within described untwisting hole h.
The material of described body is kirsite.Described sharp angle α is 15 ° ~ 22 °.Described spray-hole g is boring, and its outer end is stopped up by the stifled post of spray-hole.The feed end of described charging groove is provided with the baffle plate being fixed on described body, has the charging breach corresponding with described charging groove on described baffle plate.The material of described baffle plate is stainless steel.Between the center line of the extended line of described f channel centerline and described spray-hole g, form acute angles beta.
Described acute angles beta is 50 ° ~ 60 °.O shape circle is installed in described e passage.The bottom of described body is lined with liner, has the d passage communicating with described e passage on described liner.
Technique effect of the present invention is: in the present invention, untwisting device body is that metal material is one-body molded, intensity and precision are high, are not easy to produce distortion and wearing and tearing, have improved stability in use and the reliability of product, extend service life, reduced maintenance and cost of upkeep; Charging breach on body baffle plate, makes untwisting device can correctly capture reliably the end of the untwisting fiber of wanting processed, has got rid of any phenomenon that does not arrive the operating position of splicing.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ Fig. 5, comprise that spray-hole blocks up post 1, set bolt 2, upper shell 3, liner 4, O shape circle 5, untwisting fiber 6, thread board hold-down screw 7, alignment pin 8, baffle plate 9, baffle plate hold-down screw 10, thread board 11, body 12, charging groove 13 etc.
As shown in Fig. 1 ~ Fig. 3, the present invention is a kind of eddy flow untwisting device of twisting with the fingers specialty yarn for S, comprises body 12, and body 12 is fixed on the upper shell 3 of air splicer by set bolt 2, and be positioned at the outside of thread board 11, thread board 11 is fixed on body 12 by thread board hold-down screw 7.
As shown in Fig. 3 ~ Fig. 5, body 12 is made by metal material, preferably by the moulding of kirsite integrated die-casting.The top of body 12 is furnished with the untwisting hole h of level, and the top of body 12 is provided with the charging groove 13 of the untwisting fiber 6 inner crossing with untwisting hole h.The feed end of charging groove 13 is provided with by baffle plate hold-down screw 10 and is fixed on the baffle plate 9 on body 12, and the material of baffle plate 9 is stainless steel.On baffle plate 9, have the charging breach corresponding with charging groove 13, make untwisting device can correctly capture reliably the end of the untwisting fiber 6 of wanting processed, got rid of any phenomenon that does not arrive the operating position of splicing, especially to there being the yarn of rigidity as more obvious in flax and the thick branch line effect of some multiplies.
In body 12, be furnished with the e passage, f passage and the spray-hole g that are interconnected from bottom to top.Spray-hole g and untwisting hole h are arranged in the both sides of charging groove 13.Spray-hole g is horizontally disposed, between the extended line of its center line and the center line of untwisting hole h, forms sharp angle α, and sharp angle α is 15 ° ~ 22 °, along with the increase of α angle, and can be more obvious for the untwisting effect of high-twist yarn.The diameter of spray-hole g is less than the diameter of untwisting hole h and the top that spray-hole g is inscribed within untwisting hole h.Spray-hole g is boring, and its outer end is stopped up by the stifled post 1 of spray-hole.
F passage is gas storage air bag, between the extended line of f channel centerline and the center line of spray-hole g, forms acute angles beta, and acute angles beta is 50 ° ~ 60 °.
The bottom of body 12 is lined with liner 4, and be positioned on upper shell 3 by alignment pin 8, on liner 4, have the d passage communicating with e passage, the O shape circle 5 sealing is installed in e passage, d passage communicates with c passage or b passage in upper shell 3, and c passage or b passage communicate with the main gas passage of a in air splicer upper shell 3.Compressed air is connected with two untwisting device bodies 12 of spiral-flow detwisting air twist splicer respectively after the main gas passage of a enters respectively b passage in Fig. 2 and c passage.
Operation principle of the present invention and the course of work are as follows: air-flow flows into e passage from d passage, by f passage, enter spray-hole g again, because the aperture of spray-hole g is very little, so produce very large air-flow in course of injection, because spray-hole g and untwisting hole h are inscribed within top mutually, therefore the air-flow by spray-hole g produces powerful swirling eddy at the inwall of untwisting hole h, make S twist with the fingers to yarn obtain good untwisting.
In the present invention, untwisting device body 12 is formed in one, and does not have the error of split assembling generation after machining, and has guaranteed the uniformity of untwisting device product; In addition, the zinc alloy diecasting that body 12 is integrated, is not easy to produce distortion and wearing and tearing, has improved stability in use and the reliability of product, has extended service life, has reduced maintenance and cost of upkeep.
