Description

A kind of four roller three rove feed three collecting-spinning devices

Technical field

The utility model relates to spinning new technical field, and specifically a kind of four roller three rove feed three collecting-spinning devices.

Background technology

Drafting system is the important component part of fine spining machine work, and its performance directly has influence on yarn quality.General fine spining machine all adopts three roller draft forms at present, comprising the two rubber ring structures of three common rollers and three roller four rubber ring structures that can realize 80 ~ 100 times of high drafts.The two rubber ring structures of three common rollers are 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 middle part friction field a little less than, drafting multiple is generally less than 1.4 times, this total drafting multiple to raising fine spining machine is unfavorable, thereby its total draft multiple is between 20 ~ 50.In order to solve the problem that back area draft ability is low, in Chinese patent " for the device that involves of high-count worsted the machine " (patent No.: 96107383) with " fine spining machine four tape drawing mechanisms " (patent No.: 012439010) disclose respectively a kind of three roller three-aprons and three roller four tape drawing mechanisms, the weak problem of back area draft ability that preferably resolves three roller form drafters, makes total draft multiple can bring up to 100.But, because it adopts three roller forms, also only have two draw zones, thereby can not realize super draft.For this, in Chinese patent " fine spining machine four apron the high draft devices " (patent No.: disclose a kind of four apron high draft mechanisms for fine spining machine 200520073617.2), total draft multiple is brought up to 150.

At present textile clothing industry in one follow the fashion, diversification and high-quality epoch, people are also improving constantly for the requirement of garment material, although above-mentioned published drafting system has improved total traction multiple greatly, rear roller is that single rove feeding mode makes Yarn color style lower; The front and back district of device relies on roller above and roller frictional influence yarn quality below, but this simple processing mode easily causes coarse sand beam splitting, mixes the inhomogeneous and rear untight situation of fiber strip twisting, cannot meet people's development new demand to textile raw material now, restrict spinning efficiency, affected yarn quality.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of four roller three rove and feeds three collecting-spinning devices.

For achieving the above object, the utility model adopts following technical scheme: a kind of four roller three rove feed three collecting-spinning devices, comprise the cotton bellows of collection, the first break draft roller pair being formed by rear roller and rear roller, middle rear roller with in after the middle first break draft roller pair that forms of roller, the middle front draft roller pair that middle front roller and middle front leather roller form, front roller and front leather roller, the front draft roller pair that resistance twist roller forms, the lever jack position of described rear roller adds three horn mouth feeding units, on described rear roller, install a kind of mechanical type magnetic collector additional, described middle rear roller jaw place adds cuts apart roller arrangement, on described middle front roller, install a kind of mechanical type magnetic collector additional, the cotton bellows of described collection surface arranges two air channels and comprises the first air channel and the second air channel, described the second air channel is connected with narrow slot type negative pressure front roller, the cotton bellows of described collection inside arranges the automatic cotton-sweeping equipment of pressure sensitive, described narrow slot type negative pressure front roller is the steel hollow roller of a diameter 50mm, described steel hollow roller surface is provided with the narrow groove of arranging according to certain rule, air draught assembly is equipped with in its inside.

Adopt after said structure, can realize three rove and feed spinning simultaneously, effectively improve Yarn color style, simultaneously by install a kind of mechanical type magnetic collector additional at rear roller, and be engaged in middle rear roller and install additional and cut apart three rove that roller arrangement realizes feeding in the drawing-off of back zone and evenly mix, on middle front roller, install mechanical type magnetic collector additional, can realize the tight set effect before entering proparea dominant draft of fiber strip after mixing, front roller adopts a kind of major diameter narrow slot type negative pressure hollow roller, the fiber strip that can effectively realize after drawing-off is twisted under compact state, significantly improve yarn quality, on the other hand, adopt the four row drawing rollers can be by two draw zones of original three laura structures: front draft zone and first break draft district, rise to three present draw zones: front draft zone, middle draw zone and first break draft district, effectively improve drafting multiple, total draft multiple is the highest to be brought up to more than 300 times, thereby can realize three kinds of general quantitative rove and feed spinning simultaneously, effectively improve spinning efficiency.
