Description
Art
The present invention relates to textile machine auxiliary equipment field, especially, be a kind of for weft yarn spray
Penetrate position and keep structure.
Background technology
After loom is formed shed open by shedding mechanism, with arrow shaft, injection fluid, projectile shuttle or shuttle
The motion that weft yarn introduces shed open Deng weft carrier is referred to as wefting insertion, and weft yarn is sprayed extremely by the shower nozzle of loom
Bu Wei mechanism, it is necessary to carry out beating-up after completing wefting insertion action, beating is on loom,
Rely on reciprocally swinging before and after reed, push the weft yarn introducing shed open one by one to fell, with warp thread
Interweave, form the process meeting the fabric that design requires, while having beaten up, weft yarn two ends
Cutting mechanism just weft yarn is sheared, the weft yarn after cutting off is carried out drawing next time by weft carrier again
Latitude action.
When cutting mechanism cuts off weft yarn, ejection end there is also stretching weft threads to the weft yarn of beating end
Tension force, therefore after breakage of weft, owing to weft yarn itself exists certain elasticity, weft yarn can resilience
To carrier (such as on shower nozzle) or the weft yarn state sagging owing to gravity is in, therefore,
When the shower nozzle of ejection end carries out wefting insertion next time, the jet head of injection breaks can be because of the latitude of bending
Yarn and lose bigger kinetic energy, jet more can be made to splash, have a strong impact on the quality of beating.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of weft yarn eject position and protect
Holding structure, this weft yarn eject position keeps structure the weft yarn after cutting off can be made to have preferably throw
Latitude attitude.
The technical solution adopted for the present invention to solve the technical problems is:
This weft yarn eject position keeps structure to include the elastic solenoid being arranged on weft yarn jet,
Described elastic solenoid is coaxially disposed with weft yarn jet and one end is fixed on the spray of described weft yarn
On loophole, described elastic solenoid by a movement controller by the power on/off to elastic solenoid
Realize shrinking and elongation, described movement controller elasticity of elongation solenoid after weft yarn is cut off,
Weft yarn shrinks elastic solenoid while carrying out wefting insertion.
As preferably, the outer circumference of described elastic solenoid is evenly equipped with at least two and elastic helical
The slide rail that coil axis is parallel, described elastic solenoid is provided with the cunning coordinated with described slide rail
Hole, the non-weft yarn jet end of described elastic solenoid is fixing with described slide rail to be connected, described cunning
Rail is slidably arranged in weft yarn jet, and arranging of slide rail effectively controls described elastic solenoid
Movement locus keeps straight line.
As preferably, described elastic solenoid is passed through spring by the slip ring of integrated some circle loop
Concatenation forms, and described slide opening is arranged on the periphery wall of described slip ring, by some circle loop
Overlap, the speed that elastic solenoid is shunk after energising can be increased, be beneficial to improve spray and knit speed.
As preferably, it is coated with tubular elastomeric film between described elastic solenoid or slip ring, pipe
Shape elastic membrane arrange can support shute further, make weft yarn keep straight line attitude.
It is an advantage of the current invention that:
The characteristic extended after utilizing described elastic solenoid energising after-contraction, power-off, makes elastic spiral shell
Coil completes to shrink the action of elongation, the elastic solenoid that after making beating, the weft yarn of fracture is stretched
Adjust to linear state, the obstacle that when reducing injection, weft yarn is formed because of bending, improve beating
Quality.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
In the present embodiment, refering to Fig. 1 and Fig. 2, this weft yarn eject position keeps structure to include
It is arranged on the elastic solenoid 100 of weft yarn jet 400, described elastic solenoid 100 and latitude
Yarn jet 400 is coaxially disposed and one end is fixed on described weft yarn jet 400, described
Elastic solenoid 100 by a movement controller by the power on/off of elastic solenoid 100 is realized
Shrinking and elongation, described movement controller is elasticity of elongation solenoid after weft yarn 10 is cut off,
Weft yarn 10 shrinks elastic solenoid while carrying out wefting insertion.
Described movement controller, with traditional logic circuit, the action sensor of loom is to bullet
Property solenoid 100 is controlled.
Above-mentioned weft yarn eject position keeps structure, and the outer circumference of described elastic solenoid 100 is uniform
There are four slide rails 200 paralleled with elastic solenoid axis, described elastic solenoid is arranged
There are the slide opening 210 coordinated with described slide rail 200, the non-weft yarn jet of described elastic solenoid
Holding be connected fixing with described slide rail 200, described slide rail 200 is slidably arranged in weft yarn jet
In 400.
Above-mentioned weft yarn eject position keeps structure, and described elastic solenoid is by integrated some circle wires
The slip ring of circle 130 is formed by spring 120 concatenation, and described loop 130 is by described spring
Setting up electrical connection, described slide opening 210 is arranged on the periphery wall of described slip ring,
Refering to Fig. 1 and Fig. 3, between described slip ring, it is provided with the pipe in the space closed between slip ring
Shape elastic membrane 300, described tubular elastomeric film 300 can use traditional elastomeric material to make.
The working method of above-mentioned weft yarn eject position holding structure and principle:
Refering to Fig. 4, when weft yarn jet 400 sprays weft yarn 10, due to the jet of injection
Weft traction 10 advances, and therefore the loop 130 in slip ring is energized, due to magnetic pole opposite sex phase
The principle inhaled, shrinks (i.e. elastic solenoid is shunk), the contraction of elastic solenoid between slip ring
Can avoid affecting jet and the motion of weft yarn 10, the elastic solenoid simultaneously shunk also reduces
The pressure born because of beating, after having beaten up, weft yarn 10 is sheared mechanism and cuts off, therefore
Loop 130 power-off in slip ring, due to the resilience of spring 120, elastic solenoid elongation,
Post-rift weft yarn 10 is kept linear state, waits that weft yarn jet 400 sprays again.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, all
Within protection scope of the present invention should being included in.
