Special anti-breakage feeding device for doubling machine

Abstract

The invention provides a yarn end breakage preventing feeding device special for a doubling winder. The yarn end breakage preventing feeding device is high in feeding efficiency and can effectively prevent filament yarn end breakage. The yarn end breakage preventing feeding device comprises a vertically-arranged rack, wherein a burdening zone is arranged at the lower end of the rack, a plurality of hexagonal burdening discs are evenly distributed in the burdening zone, and supporting bowls with arc-shaped bottoms are arranged in a part of burdening discs. A filament yarn drafting support and a drum yarn drafting support are arranged above the burdening zone, a first tension controller is arranged above the filament yarn drafting support and the drum yarn drafting support, and a second tension controller is arranged on the rack above the first tension controller. A detection device is further arranged between the filament yarn drafting support and the drum yarn drafting support and the first tension controller and is used for monitoring whether filament yarns or drum yarns break or not in real time.

Description

technical field [0001] The invention relates to textile equipment, in particular to a yarn doubling machine feeding device. Background technique [0002] In the spinning process of the doubling machine, the raw materials include filament and package yarn. In order to ensure production capacity, it is necessary to distribute a large number of filament rolls and packages in a small space in an orderly manner. In the prior art, the filament rolls are generally placed on the ground, and the bobbins are arranged through the creel, which occupies a large space and is inconvenient for pulling operations. [0003] In addition, the synthetic fiber filaments used as raw materials are packaged in flat bobbins. Since the filament rolls have a large diameter close to 40cm, and the filaments are very smooth, their friction coefficient is small, and the winding density of the filaments provided by various raw material manufacturers It is not nearly the same, so when parking, the filament...

Problems solved by technology

In the prior art, the filament rolls are generally placed on the ground, and the bobbins are arranged on creels, which takes up a lot of space and is inconvenient for traction

[0003] In addition, the synthetic fiber filaments used as raw materials are packaged in flat bobbins. Since the filament rolls have a large diameter close to 40cm, and the filaments are very smooth, the coefficient of friction is small. In addition, the winding density of the filaments provided by various raw material manufacturers Therefore, when parking, the filament at the free end will slide down from the filament roll due to its own weight. Under the influence of other factors such as wind, the shape of the filament will no longer be regular, and some filaments will drift to the bottom of the filament cake, and the When starting the machine, the filament is interfered by the body of the filament reel, so that the traction is not smooth, and even the filament is broken due to excessive tension, resulting in defects in the gray fabric
