Description

A kind of three rove feeding bell mouth arrangement

Technical field

This utility model relates to new technical field of spinning, a kind of 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 three rove feeding bell mouth arrangement, including front horn mouth and rear horn mouth, front horn mouth bag Include upper and lower two horn mouths, add arc yarn-guiding duct at the rear portion of rear bell-mouthed upper port, feed while then realizing three rove.

Summary of the invention

This utility model provides a kind of three rove feeding bell mouth arrangement, by using one to include upper and lower two horn mouths at front horn mouth, at rear loudspeaker The rear portion of the upper port of mouth adds arc yarn-guiding duct, it is achieved feed while three rove, uses arc yarn-guiding duct, it is achieved smoothing of rove Feeding, improves yarn quality.

In order to solve the problems referred to above, the technical scheme that this utility model is taked is: a kind of three rove feeding bell mouth arrangement, including upper horn mouth and under Horn mouth, described upper horn mouth includes upper left horn mouth and upper right horn mouth, described upper left horn mouth and upper right horn mouth symmetrically structural arrangement, institute State upper left horn mouth and include that the first upper port and the first lower port, described first upper port and the first lower port are half elliptic, described upper left horn mouth Bore be gradually reduced along the first upper port to the first lower port direction, described upper right horn mouth includes the second upper port and the second lower port, described Second lower port is half elliptic, and described second upper port is half elliptic, and the bell-mouthed bore of described upper right is along the second upper port to the second lower end Mouth direction is gradually reduced, and described upper left horn mouth and upper right horn mouth are mutually tightly fastened connection by plane side, and described lower horn mouth includes the 3rd Upper port and the 3rd lower port, described 3rd lower port is oval, and the left demifacet of described 3rd upper port is half elliptic, described 3rd upper port The arcwall face that right-half plane is indent, the right-half plane in described 3rd upper port adds arc yarn-guiding duct, the downside of described arc yarn-guiding duct, Left surface and right flank are the arcwall face of indent, and left demifacet and first lower port of described 3rd upper port are tightly fastened connection.

During use, bell mouth arrangement is fixed on the top of rear roller, and first and second rove are respectively from upper bell-mouthed upper left horn mouth and upper right Bell-mouthed first upper port and the feeding of the second upper port, common entrance the 3rd upper port, the 3rd rove after the first lower port and the second lower port The 3rd upper port is entered by the right-half plane of the 3rd upper port through arc yarn-guiding duct, and defeated through the 3rd lower port after converging with first and second rove Go out.

This utility model, by using one to include upper and lower two horn mouths at front horn mouth, adds arc at the rear portion of rear bell-mouthed upper port and leads Yarn channel, it is achieved feed while three rove, uses arc yarn-guiding duct, it is achieved the smooth feeding of rove, improves yarn quality.

Detailed description of the invention

A kind of three rove feeding bell mouth arrangement, including upper horn mouth 1 and lower horn mouth 2, upper horn mouth 1 includes upper left horn mouth 3 and upper right loudspeaker Mouth 4, upper left horn mouth 3 and upper right horn mouth 4 symmetrically structural arrangement, upper left horn mouth 3 includes the first upper port and the first lower port, the One upper port and the first lower port are half elliptic, and the bore of upper left horn mouth 3 is gradually reduced along the first upper port to the first lower port direction, right Upper horn mouth 4 includes the second upper port and the second lower port, and the second lower port is half elliptic, and the second upper port is half elliptic, upper right horn mouth The bore of 4 is gradually reduced along the second upper port to the second lower port direction, and upper left horn mouth 3 and upper right horn mouth 4 are the tightest by plane side Close fixing connection, lower horn mouth 2 includes that the 3rd upper port and the 3rd lower port, the 3rd lower port are oval, and the left demifacet of the 3rd upper port is half Ellipse, the arcwall face that right-half plane is indent of the 3rd upper port, the right-half plane in the 3rd upper port adds arc yarn-guiding duct 5, arc guide The downside of passage 5, left surface and right flank are the arcwall face of indent, and left demifacet and first lower port of the 3rd upper port are tightly fastened connection.

During use, bell mouth arrangement is fixed on the top of rear roller, and first and second rove are respectively from upper left horn mouth 3 He of upper horn mouth 1 First upper port of upper right horn mouth 4 and the feeding of the second upper port, common the 3rd upper port that enters after the first lower port and the second lower port, the 3rd Root rove is entered the 3rd upper port through arc yarn-guiding duct 5 by the right-half plane of the 3rd upper port, and through the 3rd after converging with first and second rove Lower port exports.
