Abstract

The utility model provides a S type horn mouth device, the device include preceding horn mouth, well horn mouth and back horn mouth, and preceding horn mouth, well horn mouth and back horn mouth journey S type are connected, and the bore of preceding horn mouth reduces from the front end to the rear end gradually, and the bore of well horn mouth remains unchanged from the front end to the rear end, and the bore of back horn mouth reduces from the front end to the rear end gradually. The utility model discloses a be the horn mouth device of S type, realizes the S type route feeding of roving before getting into the drafting zone of feeding, can realize improving the stability that the roving got into the drafting zone to the tension stationarity control of feeding roving, improves yarn quality then.

Description

A kind of S type bell mouth arrangement

Technical field

The utility model relates to spinning new technical field, specifically a kind of S type bell mouth arrangement.

Background technology

Compact spinning is a kind of ring spinning new technology, and its principle on traditional ring throstle, installs a fibre deposition device additional, to reduce or eliminate twist triangle zone, thus significantly reducing resultant yarn filoplume, improve yarn strength, the Yarn break of later process is reduced, and production efficiency is high.In compact spinning process, rove enters draw zone through horn mouth, yarn after drawing-off is subject to gathering effect above Nesting Zone, and bell-mouthed installation site have impact on the position that yarn enters draw zone, thus affect the compacting effect of Nesting Zone to yarn, yarn forming performance is impacted.Bell-mouthed structure can have an impact to the state that feeding rove enters draw zone, then affects yarn quality.

For above-mentioned phenomenon, the utility model provides a kind of S type bell mouth arrangement, this device comprises front horn mouth, middle horn mouth and rear horn mouth, front horn mouth, middle horn mouth are connected with rear horn mouth journey S type, front bell-mouthed bore reduces gradually from front end to rear end, in bell-mouthed bore remain unchanged from front end to rear end, rear bell-mouthed bore reduces gradually from front end to rear end.The utility model adopts a kind of S-type bell mouth arrangement, realizes the S type route feeding of rove before entering draw zone of feeding, can realize controlling the tension force stationarity of feeding rove, improve the stability that rove enters draw zone, then improve yarn quality.

Summary of the invention

The utility model provides a kind of S type bell mouth arrangement, by adopting a kind of S-type bell mouth arrangement, realize the S type route feeding of rove before entering draw zone of feeding, can realize controlling the tension force stationarity of feeding rove, improve the stability that rove enters draw zone, then improve yarn quality.

In order to solve the problem, the technical scheme that the utility model is taked is: a kind of S type bell mouth arrangement, comprise front horn mouth, middle horn mouth and rear horn mouth, described front horn mouth, middle horn mouth and the S-type connection of rear horn mouth, described front bell-mouthed bore reduces gradually from front end to rear end, in described, bell-mouthed bore remains unchanged from front end to rear end, and described rear bell-mouthed bore reduces gradually from front end to rear end.

During use, rove successively through front horn mouth, middle horn mouth and rear horn mouth, then feeds draw zone, after drawing-off effect, twists resultant yarn after laying out from rove cylinder.

The utility model is by adopting a kind of S-type bell mouth arrangement, realize the S type route feeding of rove before entering draw zone of feeding, can realize controlling the tension force stationarity of feeding rove, improve the stability that rove enters draw zone, then improve yarn quality.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

A kind of S type bell mouth arrangement, comprise front horn mouth 1, middle horn mouth 2 and rear horn mouth 3, front horn mouth 1, middle horn mouth 2 and the S-type connection of rear horn mouth 3, the bore of front horn mouth 1 reduces gradually from front end to rear end, the bore of middle horn mouth 2 remains unchanged from front end to rear end, and the bore of rear horn mouth 3 reduces gradually from front end to rear end.

During use, rove successively through front horn mouth 1, middle horn mouth 2 and rear horn mouth 3, then feeds draw zone, after drawing-off effect, twists resultant yarn after laying out from rove cylinder.

Claims

1. a S type bell mouth arrangement, comprise front horn mouth, middle horn mouth and rear horn mouth, it is characterized in that: described front horn mouth, middle horn mouth and the S-type connection of rear horn mouth, described front bell-mouthed bore reduces gradually from front end to rear end, in described, bell-mouthed bore remains unchanged from front end to rear end, and described rear bell-mouthed bore reduces gradually from front end to rear end.
