Description

A kind of RING SPINNING back zone untwisting device
Technical field
The utility model relates to spinning new technical field, specifically a kind of can being installed in ring throstle first break draft district to realize the device of the further backtwisting of yarn.
Background technology
RING SPINNING technology is current domestic and international application the most a kind of spinning technique, but this technology is because the existence of twist triangle zone makes the quality of yarn not as the quality of match doff line.Because ring spun yarn twist triangle zone is larger, the tail end of limit fiber is difficult for being entered sliver and forming filoplume by winding on the one hand; Simultaneously limit fiber is subject to tension difference larger with center fiber, ruptures, thereby can not make full use of every filamentary brute force and reduce single end strength when different when stretching.Therefore for the research of frame spinning twist triangle zone, become the heat subject of textile limit, and aspect engineering practice and theoretical research, obtaining a series of plentiful and substantial achievements in research.The ring throstle that main flow is used at present all adopts tri-roller double area draft, and wherein preliminary draft and backtwisting effect are mainly played in first break draft, also realizes the drawing-off arrangement effect to feeding yarn, and front draft zone is main drawing area, mainly plays drawing-off effect.Because the rove feeding has certain twist, therefore, first the yarn that enters back zone needs to carry out backtwisting, so that it is more neat to enter the yarn in proparea, then realizes drawing-off more fully.For above-mentioned reasons, back zone drafting multiple is subject to certain limitation, therefore how to realize the further backtwisting effect of back zone to feeding yarn, then improves drawing-off ability and the proparea drawing-off more fully of back zone, improve drawing-off effect, improve yarn quality and become current urgent problem.
For this, the utility model provides a kind of being installed in ring throstle first break draft district and realizes feeding the device of the further backtwisting of yarn.This device is configured in first break draft district, by connecting rod, be fixed on rove feeding horn mouth Traverse Displacement Unit, device is cylindrical structural, comprise outer surface and inner surface, it between outer surface and inner surface, is hollow-core construction, the rear port that outer surface is connected with inner surface is enclosed construction, front port is with certain domatic enclosed construction, at front port, contain negative pressure connector, on the inner surface between front port and rear port, have evenly distributed circular hole, in spinning process, yarn is from horn mouth feeding, enter the inner surface passage of untwisting device, it is hollow-core construction that negative pressure enters between outer surface and inner surface through negative pressure connector, then the circular hole by inner surface acts on yarn, realize the further backtwisting of yarn, improve yarn quality, improve back area draft effect.
Summary of the invention
The purpose of this utility model is to provide a kind of can being installed in ring throstle first break draft district to realize the device of the further backtwisting of yarn.
For achieving the above object, the utility model comprises three roller drafting devices: the front roller drawing-off pair being comprised of front roller and front leather roller, the middle roller drawing-off pair being formed by middle roller and medium rubber roller, the rear roller drawing-off pair being formed by rear roller and rear roller, in described first break draft district, be rear roller drawing-off pair and middle roller drawing-off between add a kind of untwisting device, described untwisting device is fixed on rove feeding horn mouth Traverse Displacement Unit by connecting rod, described untwisting device is cylindrical structural, described cylindrical untwisting device comprises outer surface and inner surface, it between described outer surface and inner surface, is hollow-core construction, the rear port that described outer surface is connected with inner surface is enclosed construction, the front port that described outer surface is connected with inner surface is with certain domatic enclosed construction, at described front port, contain negative pressure connector, on the inner surface between described front port and rear port, have evenly distributed circular hole, the diameter of described inner surface is between 5-10mm, length is between 18-22mm, outer surface diameter is between 10-15mm, length is between 15-17mm, the Circularhole diameter of described inner surface is between 1-2mm.
Further, above-mentioned untwisting device needs negative pressure to realize backtwisting effect, thereby for saving negative-pressure air fan, the saving improvement cost of required interpolation, draws a negative pressure air channel, for untwisting device provides required negative pressure on the cotton bellows of former ring throstle collection.
In spinning process, rove yarn is fed by rear roller from horn mouth, then enter the inner surface passage of untwisting device, negative pressure is drawn in collecting cotton bellows, and by negative pressure connector, entering between outer surface and inner surface is hollow-core construction, and the circular hole by inner surface acts on yarn surrounding then, yarn is backtwisting under the absorption of surrounding negative pressure, then realize yarn at the further backtwisting of back zone, improve yarn quality, improve back area draft effect.
The beneficial effects of the utility model are: by add inside to have the device of negative pressure in back zone, make yarn backtwisting under the absorption of surrounding negative pressure of back zone, then realize yarn at the further backtwisting of back zone, improve yarn quality, improve back area draft effect, can effectively improve the drawing-off ability of back zone, then improve total draft multiple, for high grade yarn, produce and lay the foundation simultaneously.
