The utility model is characterized in that the cylindrical driving rollers comprise four and are respectively arranged in elongated slots of the oblong roller slide blocks 15, 16 and 17 of the oblong roller stool 24, the cylindrical driven rollers 5, 6, 7 and 8 are respectively pressed on the cylindrical driving rollers 1, 2, 3 and 4 through the original cocket centring, the arc-shaped upper pins 12, 13 and 14 are respectively assembled on the cylindrical driven rollers 6, 7 and 8, the appearance surface of the cylindrical driven rollers are respectively sheathed with upper aprons 21, 22 and 23, the oblong roller slide blocks 15, 16 and 17 are provided with the necks of the lower pins to fix the lower pins 9, 10 and 11, the lower pins 10 and 11 are sheathed with lower aprons 19 and 20 through the cylindrical driving rollers 3 and 4, and the lower pin 9 and an apron tension bracket 28 fixed on the roller stool 24 are sheathed with a lower apron through the cylindrical driving roller 2.
Description
One, technical field
The utility model has related to ring spinning frame drawing-off technology, is specially a kind of ring spinning frame four rollers six apron drafting arrangements.
Two, background technology
The traditional drawing-off form of fine spining machine is to adopt three roller double belt drafting mechanisms, have two draw zones, be divided into front draft zone and first break draft district, then draw zone adopts simple roller draft, the middle part friction field of this drawing-off a little less than, space to come the controlling fiber motion by changing roving twist and regulating the back zone often, and back zone drafting multiple is generally less than 1.4 times, if drafting force is excessive, be easy to produce the excessive problem of drafting wave, cause yarn quality to worsen, so this is very unfavorable to improving fine spining machine total draft multiple.Further the present this drawing-off form of research and analysis is difficult to improve the total draft multiple of fine spining machine, so exists the place that is further improved under the prerequisite of ensuring the quality of products.
Three, summary of the invention
The purpose of this utility model provides a kind of ring spinning frame roller six apron drafting arrangements, the proparea drafting multiple that solves present conventional spinning frame is generally at 20～30 times, the total draft ability is generally below 50 times, the back total draft ability that goes beyond the scope is lower, most critical is that back zone drafting multiple is little, is difficult to guarantee the problem of yarn quality.Carry out the drawing-off form improves for this reason: the one, increase a draw zone, and form three draw zones, be to spin big regular roving feeding in order better to adapt to, also be in order to improve the total draft ability of fine spining machine.Combination by three draw zones, can make bigger regular roving feeding be subjected to more rational drawing-off distributes, it is quantitative greatly in order better to adapt to rove designing three draw zones, forming the ladder drawing-off in the high drafting process distributes, emphasis is to prevent in drafting process, cause the sliver merokinesis because of drawing-off is excessive, reduce the weak ring section of details and behind high drafting, produce possibility thick, details, thereby prevent generation thick, details.The 2nd, in, the first break draft district increased up and down cushion rubber respectively, formed positive transmission, thereby guarantee effective control to sliver, add persistent erection, back area draft to the control of fiber movement and to the adaptability of fibre length, make closely contact between the fiber, increased in the sliver, the friction field intensity at rear portion, thereby improved the uniformity of resultant yarn greatly, improve into sliver CV% value.
The technical solution of the utility model realizes in the following manner:
The utility model spins fine spining machine four rollers six apron drafting arrangements by a kind of ingot, by cylindrical active roller 1,2,3,4, cylindrical passive roller 5,6,7,8, rectangle roller stool 24, rectangle roller slide block 15,16,17, sell 12 on the arc, 13,14, dihedral downside pin 9,10,11 and draw-in groove form, it is characterized in that cylindrical active roller is provided with four, be separately positioned on the rectangle roller slide block 15 on the rectangle roller stool 24,16, in 17 the elongated slot, cylindrical passive roller 5,6,7,8 are pressed in cylindrical active roller 1 respectively by original reel cage, 2,3, on 4, cylindrical passive roller 6,7, on 8, be respectively fitted with and sell 12 on the arc, 13,14, its appearance is with upper leather ring 21 respectively, 22,23, at rectangle roller slide block 15,16,17 are provided with fixedly downside pin 9 of downside pin draw-in groove, 10,11, by cylindrical active roller 3,4, downside pin 10,11 are with down apron 19,20.By cylindrical active roller 2, downside pin 9 and the apron tension bracket 28 that is fixed on the roller stool 24 are with down apron.
Increasing the apron device in middle back zone and be in order to strengthen the control to the fiber of motion, to improve bar evenness, having increased a draw zone is in order drawing-off to be distributed more evenly rationally, to improve the total draft ability, finally reaching the purpose that improves yarn quality.
The utility model advantage:
1, improve regular roving feeding, reduce rove and join platform, corresponding drafting, combing, comb and parallel cotton fibers prior to spinning all can reduce joins platform, reduces recruitment, and energy resource consumption is few, reduces production costs greatly.
2, improve yarn quality, particularly become sliver to do CV% value and single thread ultimate strength.
3, solve the difficult problem that high-count yarn spun is joined the high draft multiple, be applicable to high-count yarn spun.
4, to the spinning suiting height of fiber, stable yarn quality is good.
Four, description of drawings
Fig. 1-fine spining machine four rollers six apron drafting arrangement schematic diagrames;
Five, embodiment
The utility model is achieved through the following technical solutions, and specific embodiments is as follows:
With reference to accompanying drawing 1, fine spining machine four sieve six apron drafting arrangements: four rollers initiatively a: roller 1, two rollers 2, three rollers 3, four rollers 4, be separately fixed on roller stool 24 and the roller slide block 15,16,17, roller slide block 15,16,17 can space according to regulating before and after the technological requirement, and can be fixed on the roller stool 24, on the roller slide block 15,16,17 the downside pin draw-in groove is arranged all, fixedly downside pin.Passive roller 5,6,7,8 is pressed in respectively on the active roller 1,2,3,4 by reel cage, three draw zones before, during and after the formation, be respectively fitted with pin 12,13,14 on the passive roller 6,7,8, the outside has put apron 21,22,23, and apron can freely turn round with passive roller.Following apron 18,19,20 is enclosed within respectively outside active roller 2,3,4 and the downside pin 9,10,11, and can freely turn round with roller.The front draft zone is long 18 short 21 apron draft patterns, and following apron 18 is by apron tension bracket 28 tensioning aprons, in, the first break draft district adopts the double-short leather-ring drafting system, also can adopt length apron draft pattern.Rove bar 26 through horn mouths 25 enter successively the back, in, the front draft zone forms spun yarn 27 after through three drawing-offs.
