Abstract
A kind of four roller draft self-twist spinning devices, adopt four roller draft patterns, roller, the surperficial groove had along front leather roller rotation direction of front leather roller simultaneously.The utility model adopts four roller drafts on the one hand, improves total draft multiple, to realize the exploitation of a high self-twisted yarn line; On the other hand, rear roller surface has the groove along front leather roller rotation direction, the rove yarn of feeding can be split further, then better realize the backtwisting effect in first break draft district, improve drawing-off effect, front leather roller surface has the groove along front leather roller rotation direction, the yarn after by drawing-off can be realized split further, to realize the abundant afterturn of yarn, improve the plying effect of bifilar yarn in sth. made by twisting process, improve yarn quality.
Description
Technical field
The utility model relates to spinninging technical field, relates to a kind of four roller draft self-twist spinning devices specifically.
Background technology
Drafting system is the important component part of fine spining machine work, and its performance directly has influence on yarn quality.Fine spining machine general at present all adopts three roller draft forms, comprising the two rubber ring structure of three common rollers and three roller four rubber ring structures that can realize 80 ~ 100 times of high drafts.The two rubber ring structure of three common rollers is divided into two draw zones: front draft zone and first break draft district, and back zone is owing to only adopting simple roller draft, make the friction field at middle part more weak, drafting multiple is generally less than 1.4 times, this is unfavorable to the total drafting multiple improving fine spining machine, and thus its total draft multiple is between 20 ~ 50.In order to solve the low problem of back area draft ability, at Chinese patent " for high-count worsted machine involve device " (number: 96107383) with " fine spining machine four tape drawing mechanism " (number: individually disclose a kind of three roller three-aprons and three roller four tape drawing mechanisms 012439010), preferably resolve the problem that the back area draft ability of three roller form drafters is weak, make total draft multiple to bring up to 100.But, because it adopts three roller forms, also namely only have two draw zones, thus can not realize super draft.For this, at Chinese patent " fine spining machine four apron high draft device " (number: disclose a kind of four apron high draft mechanisms for fine spining machine 200520073617.2), total draft multiple is brought up to 150.
Spinning from sth. made by twisting is a kind of Advanced Spinning Technologies, this technology adopts two rove to feed simultaneously, yarn two ends after drawing-off grip, middle twisting, form two and there is the positive and negative false twisting single thread replaced, abut against together by parallel for two slivers again, rely on the antitorque moment of two slivers voluntarily twisted become to have the bifilar self-twisted yarn from twisting with the fingers the twist.Main employing three roller drafts produced by current self-twisted yarn, easily produce irregular simultaneously and cause bifilar yarn plying effect in sth. made by twisting process bad in drafting process.For this, a kind of four roller super drafts are incorporated into self-twist spinning process by the utility model, roller, the surperficial groove had along front leather roller rotation direction of front leather roller after coordinating simultaneously, develop a kind of four roller draft self-twist spinning devices, improve total draft multiple on the one hand, realize the exploitation of high self-twisted yarn line, the opposing party improves drawing-off effect and the plying effect of bifilar yarn in sth. made by twisting process, improves yarn quality.
Summary of the invention
The purpose of this utility model is that a kind of four roller super drafts are incorporated into self-twist spinning process, develop a kind of four roller draft self-twist spinning devices, improve total draft multiple on the one hand, realize the exploitation of a high self-twisted yarn line, the opposing party improves drawing-off effect and the plying effect of bifilar yarn in sth. made by twisting process, improves yarn quality.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of four roller draft self-twist spinning devices, adopt four roller draft patterns, comprise the first break draft roller pair be made up of rear roller and rear roller, by middle rear roller with in after roller form in first break draft roller pair, front traction roller pair in being made up of middle front roller and middle front leather roller, the front traction roller pair be made up of front roller and front leather roller, first break draft roller to and middle first break draft roller between for first break draft district, middle first break draft roller to and middle front traction roller between be middle draw zone, middle front traction roller to and front traction roller between be front draft zone, described rear roller surface has the groove along front leather roller rotation direction, described front leather roller surface has the groove along front leather roller rotation direction.
In use procedure, by double roving by double horn mouth feeding unit from first break draft roller to feeding, successively through first break draft roller pair, middle first break draft roller pair, middle front traction roller realizes the drawing-off of 3rd district to front traction roller, yarn after drawing-off by front traction roller to output, yarn one end after output by front traction roller to gripping, the other end is by the gripping converging twizzle, grip at two and be provided with a pair between point and not only done gyration but also reciprocating oscillatjng twist roller, yarn is by the rubbing of oscillatjng twist roller, the yarn on oscillatjng twist roller both sides obtains the single thread bar that the twist is contrary, two single thread bars converge twizzle place due to respective untwisting moment of torsion resultant yarn of pooling capital.
The utility model has the advantage of: adopt four roller drafts on the one hand, improve total draft multiple, to realize the exploitation of a high self-twisted yarn line; On the other hand, rear roller surface has the groove along front leather roller rotation direction, the rove yarn of feeding can be split further, then better realize the backtwisting effect in first break draft district, improve drawing-off effect, front leather roller surface has the groove along front leather roller rotation direction, the yarn after by drawing-off can be realized split further, to realize the abundant afterturn of yarn, improve the plying effect of bifilar yarn in sth. made by twisting process, improve yarn quality.
Accompanying drawing explanation
Fig. 1 is four roller draft self-twist spinning apparatus structure schematic diagrames of the present utility model.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the utility model is described further.
As shown in Figure 1, a kind of four roller draft self-twist spinning devices, adopt four roller draft patterns, comprise the first break draft roller pair be made up of rear roller 4 and rear roller 8, by middle rear roller 5 with in after roller 9 form in first break draft roller pair, front traction roller pair in being made up of with middle front leather roller 10 middle front roller 6, the front traction roller pair be made up of front roller 7 and front leather roller 11, wherein, roller 8 surface has the groove along front leather roller rotation direction, and front leather roller 11 surface has the groove along front leather roller rotation direction.
In spinning process, by rove 1 and rove 2 by double horn mouth feeding unit 3 from first break draft roller to feeding, successively through first break draft roller pair, middle first break draft roller pair, middle front traction roller realizes the drawing-off of 3rd district to front traction roller, yarn after drawing-off by front traction roller to output, yarn one end after output by front traction roller to gripping, the other end is by the gripping converging twizzle 13, grip at two and be provided with a pair between point and not only done gyration but also reciprocating oscillatjng twist roller 12, yarn is by the rubbing of oscillatjng twist roller, the yarn on oscillatjng twist roller both sides obtains the single thread bar that the twist is contrary, two single thread bars converge twizzle place due to respective untwisting moment of torsion resultant yarn of pooling capital, then be wound on groove drum 14.
