- Spinning Or Twisting Of Yarns (AREA)
Abstract
The utility model relates to a four-roller drafting device of a ring spinning machine, which belongs to the ring spinning frame field, and solves the technical problems that hairiness is formed in a twisted sliver, and the formed yarn quality is poor. The utility model mainly comprises a collating bottom roller (11) and a supporting frame (8), wherein, the supporting frame (8) is arranged on a cradle (1), a collector (9) and a collating top roller (10) are arranged on the supporting frame (8), a front bottom pin (12) and the collating bottom roller (11) are arranged on a sliding block (14), the collector (9) and a bottom pin (12) are arranged between a front top roller (7) and a front bottom roller (13) and between the collating top roller (10) and the collating bottom roller (11), and a slit with 0.6 to 1.5 mm is arranged between the collector (9) and the front bottom pin (12). The utility model has the advantages that the device increases the total draft multiple, and ensures the formed yarn quality.
Description
One, technical field
The utility model belongs to the ring throstle field, is 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 in the utility model 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.
The technical solution of the utility model: 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 utility model compared with prior art has following beneficial effect: because the utility model 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.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the accumulator among Fig. 1 and the structural representation of preceding downside pin.
Five, the specific embodiment
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 1.1mm between accumulator 9 and the preceding downside pin 12.1.05-1.1 times of arrangement first break draft, the distance between preceding bottom roll 13 and the arrangement bottom roll 11 is 35mm.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 ganoid pottery.The material of preceding downside pin 12 is ganoid steel.
