Description

A kind of compact spinning layering negative pressure line device

Technical field

The utility model relates to spinning new technical field, specifically a kind of compact spinning layering negative pressure line device.

Background technology

RING SPINNING technology is current domestic and international application the most a kind of spinning technique, but this technology adds the generation of filoplume due to the existence of twist triangle zone.Therefore, the improvement for ring spinning technology especially its twisting process is that more popular problem is studied in spinning always, and in engineering practice and theoretical research, achieve a series of plentiful and substantial achievement in research, and such as compact spinning, solo spun, dislocation are spun.Especially compact spinning technology, it by increasing a fiber aggregate district before ring throstle draw-gear, make fiber parallel, realize twisting under state closely, be the important reform of ring spinning technical field.Because in resultant yarn process, fiber is stressed more even, obvolvent is tight, thus yarn texture and quality have had the sudden change of matter, use scale at home also expands gradually, especially nearly 5 years, from 2008 less than 1,000,000 ingots, more than 500 ten thousand ingots in 2010, by 2014 more than 2,500 ten thousand ingots, and will to increase at faster speed future.Mainly contain the compact spinning system of five kinds of different structures at present in the world, wherein four producers are that negative-pressure air-flow gathers.Therefore, suction type gather be most widely used in current Advance of Compact Spinning Technology gather form, fiber strip cross-direction shrinkage after it utilizes negative-pressure air-flow to make drawing-off, to gather and closely, and then the fiber at yarn edge is gathered to Sha Gan center effectively, reduce twist triangle zone to greatest extent, thus significantly reduce Yarn filoplume, improve fiber utilization coefficient and yarn strength.In negative pressure type compact spinning, negative-pressure air-suction pipeline of paramount importancely gathers one of parts, and its performance directly has influence on fiber aggregate effect, determines yarn quality.

For this, the utility model provides a kind of compact spinning layering negative pressure line device, comprise upper strata pipeline and lower floor's pipeline, upper strata pipeline comprises upper left pipeline, in upper pipeline and upper right pipeline, lower floor's pipeline comprises lower-left pipeline, in lower pipeline and bottom right pipeline, upper left pipeline is connected by left connecting pipe with lower-left pipeline, in upper pipeline and in time pipeline be connected by middle connecting pipe, upper right pipeline is connected by right connecting pipe with bottom right pipeline, lower-left pipeline, in lower pipeline and bottom right pipeline by horizontal connecting pipe to being communicated with, in the bottom of lower pipeline be connected with paired bye-pass, paired bye-pass comprises left bye-pass and right bye-pass, the quantity of paired bye-pass is identical with the quantity of fine spining machine one side spindle.During spinning, upper left pipeline, in upper pipeline be connected with negative pressure air channel respectively with upper right pipeline, then negative pressure is delivered to lower-left pipeline by left connecting pipe, middle connecting pipe and right connecting pipe, in lower pipeline and bottom right pipeline, lower-left pipeline, in the negative pressure of lower pipeline and bottom right pipe interior by the mutual Homogeneous phase mixing of horizontal connecting pipe, then by negative pressure by lower pipeline be delivered to paired bye-pass, then be delivered in the front roller apparatus for collecting of the corresponding spindle of paired bye-pass, act on yarn, realize gathering before fiber twisting, improve yarn quality.The utility model, by arranging upper and lower two-layer parallel cartridges, coordinates being interconnected of lower floor's pipeline simultaneously, thus reduces duct resistance, realizes the Homogeneous phase mixing of negative pressure, reduces headstock tailstock Negative Pressure Difference, and realizing gathering the stable of negative pressure provides.

Summary of the invention

The purpose of this utility model is to provide can provide the stable a kind of compact spinning layering negative pressure line device gathering negative pressure.

For achieving the above object, the technical scheme that the utility model is taked is, a kind of compact spinning layering negative pressure line device, comprise upper strata pipeline and lower floor's pipeline, described upper strata pipeline comprises upper left pipeline, in upper pipeline and upper right pipeline, described lower floor pipeline comprises lower-left pipeline, in lower pipeline and bottom right pipeline, described upper left pipeline is connected by left connecting pipe with lower-left pipeline, in described upper pipeline and in time pipeline be connected by middle connecting pipe, described upper right pipeline is connected by right connecting pipe with bottom right pipeline, described lower-left pipeline, in lower pipeline and bottom right pipeline by horizontal connecting pipe to being communicated with, in described, descend the bottom of pipeline to be connected with paired bye-pass, described paired bye-pass comprises left bye-pass and right bye-pass, the quantity of described paired bye-pass is identical with the quantity of fine spining machine one side spindle.

The beneficial effects of the utility model are: by arranging upper and lower two-layer parallel cartridges, coordinate being interconnected of lower floor's pipeline simultaneously, thus reduce duct resistance, realize the Homogeneous phase mixing of negative pressure, reduce headstock tailstock Negative Pressure Difference, and realizing gathering the stable of negative pressure provides.
