Abstract

The utility model provides a three roving feeding horn mouth devices of symmetry, including last horn mouth and lower horn mouth, it includes well horn mouth to go up the horn mouth, left side horn mouth and right loudspeaker mouth, the leading flank of well horn mouth and the arcwall face that the trailing flank was the indent, left surface and right flank are the plane, the left side horn mouth and the left and right sides of right loudspeaker mouth symmetric distribution at well horn mouth, the left surface of left side horn mouth is the arcwall face of indent, the right flank is plane and coincident with the first left surface of well horn mouth, the third right flank of right loudspeaker mouth is the arcwall face of indent, the left surface is plane and coincident with the first right flank of well horn mouth, lower horn mouth's cross -section is oval, lower horn mouth's the last end section and the well horn mouth of last horn mouth, the lower end section coincidence of left side horn mouth and right loudspeaker mouth. The utility model discloses an adopt including a left side in, the right side threely to being much of the horn mouth, realize three roving and control the symmetrical feeding on both sides from the intermediate sum, improve yarn quality.

Description

A kind of symmetrical three rove feeding bell mouth arrangement

Technical field

This utility model relates to new technical field of spinning, a kind of symmetrical three rove feeding bell mouth arrangement.

Background technology

Compact spinning is a kind of ring spinning new technique, and its principle is to install a fibre deposition device on traditional ring throstle additional, to reduce or to disappear Except twist triangle zone, thus resultant yarn filoplume being greatly reduced, improve yarn strength so that the Yarn break of later process reduces, production efficiency is high. During compact spinning, rove enters draw zone through horn mouth, and the yarn after drawing-off is gathered effect above Nesting Zone, and bell-mouthed peace Holding position have impact on yarn and enters the position of draw zone, thus affects the Nesting Zone compacting effect to yarn, impacts yarn forming performance.Horn mouth Structure can on feeding rove enter draw zone state produce impact, then affect yarn quality.

For above-mentioned phenomenon, this utility model provides a kind of symmetrical three rove feeding bell mouth arrangement, including upper and lower horn mouth, by employing include a left side, In, right three to being much of horn mouth, it is achieved three rove are from the middle and symmetrical feeding of the right and left, thus realize the symmetrical junction of three rove of feeding Stress symmetrically between structure, beneficially rove, improves yarn quality then.

Summary of the invention

The purpose of this utility model is to provide a kind of symmetrical three rove feeding bell mouth arrangement, includes that three, left, center, right are to being much of loudspeaker by employing Mouth, it is achieved three rove are from the middle and symmetrical feeding of the right and left, thus realize the symmetrical structure of three rove of feeding, beneficially between rove Stress symmetrically, improves yarn quality then.

In order to solve the problems referred to above, the technical scheme that this utility model is taked is: a kind of symmetrical three rove feeding bell mouth arrangement, including upper horn mouth With lower horn mouth, described upper horn mouth include middle horn mouth, left horn mouth and right horn mouth, described middle horn mouth include leading flank, trailing flank, One left surface and the first right flank, described in bell-mouthed leading flank and trailing flank be the arcwall face of indent, described in bell-mouthed first left surface Be plane with the first right flank, described in bell-mouthed bore be gradually reduced from top to bottom, during described left horn mouth and right horn mouth are symmetrically distributed in The bell-mouthed left and right sides, described left horn mouth includes the second left surface and the second right flank, the arc that the second left surface is indent of described left horn mouth Shape face, the second right flank of described left horn mouth be plane and with in bell-mouthed first left surface overlap, described right horn mouth includes the 3rd left surface With the 3rd right flank, the 3rd right flank of described right horn mouth is the arcwall face of indent, the 3rd left surface of described right horn mouth be plane and with middle loudspeaker First right flank of mouth overlaps, described under bell-mouthed cross section be oval, described under bell-mouthed upper end section and upper bell-mouthed middle horn mouth, The lower end section of left horn mouth and right horn mouth overlaps, described under bell-mouthed bore be gradually reduced from top to bottom.

During use, the first rove, the second rove and the 3rd rove feed through upper bell-mouthed middle horn mouth, left horn mouth and right horn mouth respectively, and Export after converging by lower horn mouth.

By employing, this utility model includes that three, left, center, right are to being much of horn mouth, it is achieved three rove feed from middle and the symmetrical of the right and left, Thus realize the symmetrical structure of three rove of feeding, beneficially the stress symmetrically between rove, improves yarn quality then.
