Abstract

The utility model relates to a cotton suction duct, including pyriform casing and tail pipe, the inside of pyriform casing is the cavity structure, the pyriform casing includes epitheca face, inferior valve face and positive shell face, evenly be provided with a plurality of holes of inhaling on the positive shell face, pyriform casing and tail pipe be articulated and inside intercommunication through the articulated joint, and the contained angle accessible rotation mode between tail pipe and the pyriform casing is adjusted. The symmetry is provided with the spoiler on the internal surface of epitheca face and inferior valve face, the spoiler is from inhaling the link extension of hole to the pyriform casing. The utility model discloses an each pressure of inhaling of inhaling the hole is the same basically. Still having set up simultaneously the spoiler, can effectively wellly having reduced the vortex that the air flows and forms in narrow and small cavity, reduced flow energy and lose, the contained angle accessible rotation mode between tail pipe and the pyriform casing is adjusted in addition, and then can adjust the orientation of air current, guarantees fixed intensity through the mode of bolt and cross seat in addition.

Description

A kind of cotton suction duct

Technical field

The utility model is related to Weaving device accessory technical field, and in particular to a kind of cotton suction duct.

Background technology

Each sucker of cotton suction duct on conventional spinning frame due to having nothing in common with each other with a distance from middle exhaust duct, so leading Cause blast different, some sucker suction is big, some holes from centre distance farther out, so suction is very little, and (each sucker suction pressure is not Together).And middle the tail pipe of conventional cotton suction duct and extraneous connection are typically connected by fixed sleeving, work generally, due to Use adjustment position, but traditional be typically difficult to dynamic adjustment.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of more preferable cotton suction duct of suction effect.

The technical scheme that the utility model solves above-mentioned technical problem is as follows：

A kind of cotton suction duct, including pyriform housing and tail pipe；The pyriform housing and tail pipe are hinged and internal by articulated joint Connection, the inside of the pyriform housing is cavity structure, and the pyriform housing includes epivalve, hypovalve and positive shell surface, described Multiple suckers are evenly arranged with positive shell surface.

Further, multiple spoilers, the spoiler are symmetrically arranged with the inner surface of the epivalve and hypovalve Extend from sucker to the connection end of pyriform housing.

Further, the header structure that is hinged is the nested Outer cylindrical shell installed and inner cylinder shell, described outer Circular Cylindrical Thin Shells and inner cylinder shell coaxial line and sealing two ends, on the inner cylinder shell oblong openings are provided with, Oblong openings make pyriform housing connect with tail pipe inside.

Further, the utility model is additionally provided with along coaxial line through Outer cylindrical shell and inner cylinder shell Bolt, the two ends of bolt are provided with Philip's head screw seat, and Philip's head screw seat is contacted with the end face lateral surface of Outer cylindrical shell.And spiral shell The position of bolt two ends and contacts side surfaces is provided with Philip's head screw seat.

Further, the pyriform housing 1 and tail pipe 2 adopt any one material in ABS, PP, PVC or PC with the side of injection Formula is manufactured.

1st, the utility model devises pears type cavity, and larger cavity causes each suction inlet to outside suction pipe apart from base This is identical, and centre is without big corner, therefore the suction pressure of each sucker is substantially identical.It is also provided with flow-disturbing simultaneously Plate, effectively middle can reduce the vortex that air is formed in the cavities, reduce energy of flow loss.

2nd, pyriform housing of the present utility model and tail pipe are hinged, and articulated joint adopts the concentric nested mounting means group in the face of cylinder Into the adjusting means of a single-degree-of-freedom, the angle between tail pipe and pyriform housing can be adjusted by rotating manner, Jin Erke The direction of air-flow is adjusted, and ensures fixed intensity by way of bolt and Crux, prevent articulated joint outside The lower deformation of power effect is separated.

3rd, pyriform housing of the present utility model and tail pipe adopt any one material in ABS, PP, PVC or PC with the side of injection Formula is manufactured, and manufacturing cost is little, and using effect is good, and reliability is high.

Specific embodiment

Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit scope of the present utility model.

As shown in figure 1, a kind of cotton suction duct, including pyriform housing 1 and tail pipe 2；The pyriform housing 1 and tail pipe 2 are by hinge Joint is hinged and internal connection, and the inside of the pyriform housing 1 is cavity structure, the pyriform housing 1 include epivalve 11, under Shell surface 12 and positive shell surface 13, in the positive shell surface multiple suckers 14 are evenly arranged with.

As shown in Figure 2 and Figure 3, multiple spoilers 17 are symmetrically arranged with the inner surface of the epivalve 11 and hypovalve 12, The spoiler 17 extends from sucker 14 to the connection end of pyriform housing.

The utility model devises pears type cavity, and larger cavity causes each suction inlet to be to the distance of outside suction pipe It is essentially identical, and centre is without big corner, therefore the suction pressure of each sucker is substantially identical.It is also provided with disturbing simultaneously Stream plate, effectively middle can reduce the vortex that air is formed in the cavities, reduce energy of flow loss.

As shown in figure 4, described be hinged the Outer cylindrical shell 16 and inner cylinder shell 15 that header structure is nested installation, institute Outer cylindrical shell 16 and the coaxial line of inner cylinder shell 15 and sealing two ends are stated, on the inner cylinder shell 15 length is provided with Square aperture 18, oblong openings 18 make pyriform housing 1 connect with the inside of tail pipe 2.
