Abstract
This invention relates to a four-roller drafting device of a ring spinning machine including a finished upper roller, a finished lower roller and a bracket set on a cradle, a collector and the finished upper roller are set on the bracket, a front lower bolt and a finished lower roller are set on a slider, the collector and the lower bolt are set between the front upper roller, the front lower roller, the finished upper roller and the lower roller and a slot of 0.6-1.5 mm is set between the collector and the front lower bolt, which increases total times of drafting and secures yarn quality.
Description
One, technical field
The invention belongs to the ring throstle field, be specifically related to a kind of drafting device with four rollers in ring spinner.
Two, background technology
Ring throstle is a kind of textile machine of using always, is used for the twisting after drawing-off step by step of cotton yarn yarn is spun into required spun yarn, and the common ring spindle spinning frame is when work, and fiber strip is subjected to the influence of roller pressurization at draw zone, makes its cross section be flat.After fiber strip is sent from front roller nip, promptly enter twisting area, high speed rotary is finished the twisting action under the effect of bottom steel traveler, thereby forms so-called " twist triangle zone " at front roller pincers position.Because the existence of twist triangle zone, each fiber unbalance stress in twisting process in the fiber strip, the inside and outside commentaries on classics taken place and claims in fiber, resultant yarn is inhomogeneous, this can influence the intensity of yarn to a certain extent, be apparent that especially it makes the fuzzy yarn of shaping many, the tensile strength of finished product spun yarn is low, and bar is done thickness inequality, of poor quality.Spinning machine is tending towards setting up a beaming device in the draw zone downstream of frame in recent years, make the flat fiber bar that leaves behind the front draft roller nip can gather bunchy through behind this device, by the twisting resultant yarn, eliminate the drawback that " twist triangle zone " exists thus then.Existing beaming device scheme is more.But be complex structure mostly, the parts of use are many, the installation and maintenance inconvenience, and it is very unsuitable especially existing ring throstle to be transformed, and it need be reequiped and change more parts, dismounting inconvenience, cost is higher.The disclosed drafting device with four rollers of CN2670385Y though it has guaranteed to have reduced filoplume under the prerequisite of spinning quality, has improved brute force.But this device yarn becomes laminated structure, can't thoroughly solve the filoplume of formation, influences yarn quality.
Three, summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, and a kind of drafting device with four rollers in ring spinner is provided.It has solved in the sliver of twisting, forms the problem of filoplume, has guaranteed yarn quality, has increased the total draft multiple.
Technical scheme of the present invention: a kind of drafting device with four rollers in ring spinner, it comprises reel cage 1, back top roller 2, back bottom roll 3, middle top roller 4, middle bottom roller 5, front upper roller 7, preceding bottom roll 13, arrangement top roller 10, arrangement bottom roll 11, support 8, it is provided with support 8 on reel cage 1, support 8 is provided with accumulator 9 and arrangement top roller 10, downside pin 12 and arrangement bottom roll 11 before slide block 14 is provided with, accumulator 9 and downside pin 12 are arranged on front upper roller 7, preceding bottom roll 13 and arrangement top roller 10, between the arrangement bottom roll 11, be provided with the slit of 0.6-1.5mm between accumulator 9 and the preceding downside pin 12.Distance between preceding bottom roll 13 and the arrangement bottom roll 11 is 35-40mm.The deviation of centre distance of front upper roller 7 and preceding bottom roll 13 is 2mm.The deviation of centre distance of arrangement top roller 10 and arrangement bottom roll 11 is 2mm.The material of accumulator 9 is any in ganoid steel, metallurgy sintered material, pottery, the glass.The material of preceding downside pin 12 is any in ganoid steel, the alloy profile.
The present invention compared with prior art has following beneficial effect: because the present invention has increased accumulator and preceding bottom pin device, and increased the total draft multiple, be provided with less slit between accumulator and the preceding downside pin, so in the sliver of twisting, make the many problems of fuzzy yarn of shaping obtain effective solution, guaranteed yarn quality.
