Abstract
The utility model relates to a traction mechanism at the rear district of a spinning machine and includes a front and lower roller, middle and lower roller, back and lower roller, and the corresponding front and upper roller, middle and upper roller and back and upper roller; a front and lower rubber ring is arranged on the middle and lower roller, a front and upper rubber ring is arranged on the middle and upper roller, a back and upper rubber ring is arranged on the back and upper roller, a back and lower rubber ring which rounds a flexible lower pin is arranged on the back and upper roller, and the flexible lower pin includes a lower pin body and is fixed on the lower pin seat of the flexible lower pin body and is through the sliding lower pin connected with the spring and the lower pin seat. As a back and lower rubber ring is arranged in the four-rubber-ring traction mechanism of the spinning machine, the traction capacity is up to 150 times, providing higher quality of finished yarn and more than 100 pieces of super-high spinning.
Description
Technical field
The utility model relates to the drafter of fine spining machine, is particularly relevant to the back area draft mechanism of fine spining machine.
Background technology
Drafting system is the executing agency of fine spining machine work, and its performance directly influences the output of spinning and the quality of resultant yarn.General fine spining machine all adopts three roller double belt drafting mechanisms, there is initiatively bottom roll of three row in this mechanism, wherein front roller than middle roller rotating speed height, middle roller than rear roller rotating speed height, the passive top roller of three row is housed on reel cage, corresponding respectively is pressed on the three row active bottom rolls, and apron is housed respectively on middle top roller and middle bottom roller participates in the proparea drawing-off, this two tape drawing mechanisms, its proparea drawing-off ability is 20-30 times, and drawing-off ability in back zone only is 1.05-2 times, thereby the total draft ability is 50 times.In order to solve the low difficult problem of back area draft ability, the patent No. is 96107383 " drafting system that is used for high-count worsted machine ", the three-apron drafter is disclosed, it is at middle top roller, install apron respectively additional on middle bottom roller and the back top roller, owing on the top roller of back, also install an apron additional, thereby make the total draft ability bring up to 100 times, but owing to below the epithelium posterius circle downside pin is housed, during fine spining machine work, sliver passes through along the downside pin end face, produce relative motion, then upper leather ring is synchronized with the movement with sliver under the drive of sieve on the back, because the relative motion of sliver and downside pin, drawing-off to sliver causes adverse effect, thereby has influence on the further raising of drawing-off ability and drawing-off quality.
Summary of the invention
The purpose of this utility model provides that a kind of drawing-off ability is higher, better fine spining machine four tape drawing mechanisms of yarn quality.
This fine spining machine four tape drawing mechanisms, comprise roller stand, preceding bottom roll is housed on roller stand, middle roller slide block and rear roller slide block, on the middle roller slide block middle bottom roller is housed, the back bottom roll is housed on the rear roller slide block, the preceding apron down of walking around downside pin and tension bracket is housed on middle bottom roller, corresponding to preceding bottom roll, front upper roller is equipped with in the top of middle bottom roller and back bottom roll, middle top roller and back top roller, the anterior epithelium cornea circle of going up pin before walking around is housed on the middle top roller, be equipped with on the back top roller and walk around the epithelium posterius circle that pin is gone up in the back, its design feature is that the back apron down of walking around the elasticity downside pin is housed on the bottom roll of back, and the elasticity downside pin is fixed on the rear roller slide block.
Above-mentioned elasticity downside pin comprises the following shank that is fixed on the rear roller slide block, be fixed on down the following key seat on the shank, one horizontal chamber is arranged at the top of following key seat, install an overhanging spring in this horizontal chamber, in the spring cavity of overhanging section insertion slip downside pin bottom of this spring, the chamber wall in the chamber wall of this spring cavity and horizontal chamber is pegged graft.
Owing to adopted the elasticity downside pin, make back effectively tensioning of apron quilt down, during work, apron is under the drive of back bottom roll under the back, be synchronized with the movement with sliver,, effectively control the motion of back zone fiber with pressure circle that is synchronized with the movement with sliver of the common formation of epithelium posterius circle, realized strengthening the purpose of draw ratio, the drawing-off ability of fine spining machine increased greatly, yarn quality significantly improves.
After fine spining machine was installed this four tape drawing mechanisms, its beneficial effect was:
1, drawing-off ability is higher, grip because two aprons have also been realized in the back zone, so the drawing-off ability of back zone can reach 6-7 doubly, and the total draft ability can realize 150 times;
That 2, has reduced Speed frames joins platform quantity, and the raising of fine spining machine total draft ability makes quantitatively just can strengthening of rove, thus reduced Speed frames join platform quantity, reduced production cost, saved the energy simultaneously;
3, the drawing-off wide accommodation of fine spining machine can both be applicable to production in enormous quantities with the spun yarn that spins different cultivars with a kind of rove, more be applicable to many kinds, small lot batch manufacture;
4, yarn quality is good, because in the proparea and the back zone of spinning, fiber all obtains actively controlling effectively, and particularly floating fiber and short flannel, thereby the bar evenness of yarn is greatly improved, and can spin the superelevation spun yarn more than 100.
