Abstract

The utility model discloses a drawing frame. The drawing frame comprises a rack, a sliver feeding cylinder, a sliver guiding roller and a sliver can, wherein the sliver feeding cylinder and the sliver guiding roller are arranged on the head of the rack and the sliver can is arranged on the tail of the rack. A can coiler is arranged on the silver can. The drawing frame further comprises a cotton feeding roller, four to six groups of drafting rollers are arranged in the middle of the rack, the first group of drafting rollers is adjacent to the cotton feeding roller, the last group of drafting rollers is adjacent to a compressing roller, an arc-shaped guide pipe is arranged between the drafting rollers and the compressing roller, one end of the arc-shaped guide pipe is contained in a horn mouth, and a narrow opening of the horn mouth is close to the compressing roller. Cotton is fed by using the cotton feeding roller, the four to six groups of drafting rollers are used for keeping tension, the compressing roller is used for compressing cotton slivers and enables the surfaces of drawn slivers to be smooth and compact, the due strength of the cotton slivers is guaranteed and the quality of yarn is improved.

Description

Drawing frame

Technical field

The utility model relates to cotton spinning apparatus field, is specifically related to a kind of drawing frame.

Background technology

The carded sliver that carding machine is produced, fiber passes through preliminary orientation, stretches the preliminary form that possesses sliver.But comb and parallel cotton fibers prior to spinning carded sliver irregularity is very large, and fiber alignment disorder in the carded sliver, most of fiber becomes hook solid state, if directly this carded sliver is spun into spun yarn, spun yarn is of poor quality.Therefore, further before spinning, needing the comb and parallel cotton fibers prior to spinning carded sliver and closing, improve bar evenness and fiber condition, with repeatedly and the method for closing further realize filamentary mixing, but drawing frame of the prior art is at drawing-off sliver stone, easily causes slender distortion or too unclamps, and causes sliver surface smooth not and smooth, make powerful reduction, affect spinning quality.

Utility model content

This practical new technical problem to be solved is to overcome drawing frame in prior art to be easily out of shape in the time of drawing-off sliver, and causes the smooth not problem in sliver surface, improves spinning quality.

The technical solution of the utility model is as follows:

Drawing frame, comprise frame, be arranged at feeding sliver can and the conducting bar roller of the head of described frame, be arranged at the sliver can of the afterbody of described frame, on described sliver can, be provided with can coiler, also comprise to cotton roller, be provided with 4-6 group drawing rollers at described central rack, wherein first group of drawing rollers vicinity is to cotton roller, the contiguous calender roller of last group drawing rollers, between described drawing rollers and described calender roller, be provided with curved catheter, one end of described curved catheter is placed in horn mouth, and described bell-mouthed slot is close to described calender roller.

By technique scheme, the utility model is fed cotton by utilizing to cotton roller, keeps tension force with 4-6 group drawing rollers simultaneously, calender roller compresses sliver, make the smooth of sliver surface change after drafting closely guarantee the due brute force of sliver, promoted the quality of yarn.

Brief description of the drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural diagrams intention of the disclosed drawing frame of the utility model embodiment.

Numeral and the represented corresponding component title of letter in figure:

1. feeding sliver can; 2. conducting bar roller; 3. give cotton roller; 4. drawing rollers; 5. curved catheter; 6. calender roller; 7, can coiler; 8, sliver can.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment

As shown in Figure 1, drawing frame, comprise frame, be arranged at the feeding sliver can 1 of the head of described frame, conducting bar roller 2, be arranged at the sliver can 8 of the afterbody of described frame, on described sliver can 8, be provided with can coiler 7, be provided with 5 groups of drawing rollers 4 at described central rack, also comprise to cotton roller 3, wherein first group of drawing rollers 4 is contiguous to cotton roller 3, the contiguous calender roller 6 of last group drawing rollers 4, between described drawing rollers 4 and described calender roller 6, be provided with curved catheter 5, one end of described curved catheter 5 is placed in horn mouth, described bell-mouthed slot is close to described calender roller 6, sliver is drawn from feeding sliver can 1 by conducting bar roller 2, actively feed and gather by the cotton roller 3 of giving in frame, evenly enter drawing rollers 4, because first group of drawing rollers 4 are contiguous to cotton roller 3, therefore sliver can keep original tension force and structure in the time entering, can not produce distortion, sliver after drawing-off is drawn as thin slice, then send into curved catheter 5, curved catheter 5 can be to sliver boundling and guiding, sliver is after horn mouth is gathered slivering, calender roller 6 can compress sliver, make the smooth tight of its change, sliver is placed in sliver can 8 through the regular dish of can coiler 7.

Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.

Claims

1. drawing frame, comprise frame, be arranged at feeding sliver can and the conducting bar roller of the head of described frame, be arranged at the sliver can of the afterbody of described frame, on described sliver can, be provided with can coiler, it is characterized in that, also comprise to cotton roller, be provided with 4-6 group drawing rollers at described central rack, wherein first group of drawing rollers vicinity is to cotton roller, the contiguous calender roller of last group drawing rollers, between described drawing rollers and described calender roller, be provided with curved catheter, one end of described curved catheter is placed in horn mouth, described bell-mouthed slot is close to described calender roller.
