Abstract
A four roller tension device of the utility model is used on a ring spinning frame. The fiber rods which are drafted and are't twisted are arranged and assembled to be twisted. The tension device is composed of a back draft zone, a front draft zone, an arrangement zone and a gathering zone. A plurality of edge fibers in fringings can be prevented from dissipating by the tension device. The width of the fringing can be retracted. The width of the twist triangle zone at the front jaw can be decreased. The fringings can be twisted under the compact situation. The structure of the fiber is compact, the surface is smooth, hairiness is decreased and the strength is enhanced.
Description
Technical field
The utility model relates to the drafting system on the ring throstle in the field of textiles.
Background technology
In the drafting system of ring throstle, be mainly three roller double belt draftings, be divided into first break draft district and front draft zone, when the thick bar in feeding first break draft district after the drawing-off of front draft zone, at its output jaw place, yarn has become laminated structure, therefore when yarn when spinning is twisted, some edge fibers in its sheet-like fiber bar can be in some way attached in the sliver of having twisted, forms filoplume, and it is dried influence the brute force and the bar of yarn.
Summary of the invention
The purpose of this utility model is the drafting device with four rollers that will provide a kind of ring throstle to use, and it can reduce filoplume, improve brute force under the prerequisite that guarantees spinning quality.
The technical scheme that addresses the above problem is:
A kind of drafting device with four rollers, it comprises first break draft district roller and front draft zone roller in the ring throstle, its improvement is: set up output front roller 16 and collector 15, described collector 15 is flat bell mouth shape, yarn 10 enters collector 15 after passing two rollers 17 of the roller in first break draft district 12 and front draft zone 13, enters output front roller 16 by collector again.
Above-mentioned drafting device with four rollers, the cross sectional shape of described collector 15 be " " or
Type, its inclined-plane angle is 55～90 °.
The utility model changes three roller double belt draftings of ring throstle four roller double belt draftings into, promptly increases drawing-off arrangement set district, the rove bar is behind former three roller drafts, by similar bell mouth shape collector arrangement, arrangement is after twisting again after the processing of output front roller, thereby the minimizing filoplume increases powerful.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is among the figure: 10. rove bar, 11. drafting device with four rollers, 12. first break draft districts, 13. front draft zones, 14. drawing-offs arrangement set district, 15. collectors, 16. output front rollers, 17. 2 rollers, 18. travelling gears.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is given more detailed explanation.
With reference to the accompanying drawings, rove 10 is by in the feeding drafting device with four rollers 11, after roller first break draft district 12, front draft zone 13 drawing-offs, enter drawing-off Distribution Area 14, by the collector 15 that is similar to flat bell mouth shape, after sliver 10 obtains efficient set, enter into twisting apparatus through output front roller 16.Collector in the accompanying drawing is flat bell mouth shape, its head end width and ribbon 10 traverse apart from adapting, have a special device such as airflow apparatus (not shown) can make the sliver 10 after the drawing-off enter collector 15 smoothly in the collector, in the collector 15 the sliver channel cross-section be shaped as " " or
Type, its inclined-plane angle is 55～90 °, and yarn is better gathered.The collector material is engineering plastics compactings or is made by metal material.Output front roller 16 per 6 ingots, one joints by headstock place gear 18, profile of tooth belt wheel driven rotary, or are rotated by the flat belt frictional drive in every joint.Output front roller 16 rotating speeds are a little more than drawing-off two rollers 17 rotating speeds.Make sliver 10 be in tensioning state, and obtain necessarily to augment the drawing-off effect.
Claims (2)
