Description

Air deformation nozzle with a semi-cylindric block

The nozzle of the utility model is a kind of chemical fibre equipment product, specifically, is to belong to chemical-fibres filaments to be processed to critical component product in the air-texturing yarn feeding device.Chemical-fibres filaments is when the air-texturing jet, and is under the effect of blast injection, separated, being out of shape, entwining forms wire ring and make textured yarn.

For improving the quality of air-texturing, reduce the different and handled easily of ingot potential difference, the air-texturing jet product of new construction is constantly released in countries in the world.Beijing College of Chemical Fibres is in No. 86205282 patent application cases " air-texturing jet " that proposed on July 22nd, 1986, a kind of dribbling shape block body is proposed, and block body can be by the BXMP type nozzle of L shaped bar around the rocking pin swing, concrete structure see Figure of description 1. wherein＜1〉for spherical block body,＜2〉be rocking pin,＜3〉be L shaped bar, in order to make things convenient for spinning-in operation.But it is complicated that the processing and manufacturing of spherical block body and swing mechanism are still disliked, and it is littler that amplitude of fluctuation is also disliked.Have, Shandong Textile Engineering College announced the patent application case of No. 85204341 " the AIRJET TEXTURING YARN nozzles of band hemisphere block body " on September 25th, 1986 again.It adopts hemispherical block body structure, as shown in Figure 2.This utility model nozzle, in order to control the size of the head narrow slit＜6〉between convergent-divergent pipe＜4〉and seal wire pin＜5 〉, adopt the way of rotation adjusting nut＜7〉to realize, the seal wire pin is fixed in to be adjusted on the nut, when the rotation adjusting nut, the seal wire pin is inevitable along with rotation and generation move forward and backward, thereby changes the size of narrow slit between convergent-divergent pipe and the seal wire pin., owing to have the eccentric orfice＜8〉＜being throttle orifice〉of fixed position on the seal wire pin, in order to feed compressed air, when regulating, the rotation of seal wire pin must bring the rotation thereupon of eccentric orfice, and it is different that this will produce the ingot potential difference, is difficult to make high-quality textured yarn.According to 42 pages～43 pages data introductions of " synthetic fiber " magazine in May nineteen eighty-two, in the wire vent direction fixedly the time, the airintake direction of compressed air inlet and wire vent direction are 0 degree or 180 when spending, textured yarn wire ring tension stability, best in quality, so the nozzle of this utility model in use, will produce harmful effect to the quality of textured yarn.

In order to overcome above-mentioned shortcoming, the utility model released have ingot potential difference heteropole little, easy to operate, make a simple retaining silk structure, and can be before regulating nozzle core and back core apart from the time, does not rotate core throttle orifice position before the nozzle, thereby guarantee that the processing air deformation yarn obtains best in quality, device has the air-texturing jet of semicolumn block body.

The utility model is described in detail as follows, and air-texturing jet illustrates its structure and performance in conjunction with Fig. 3 along the center line schematic cross section as shown in Figure 3.The utility model by housing＜10 〉, nozzle after before the core＜11 〉, nozzle core＜12 〉, front and back core distance adjusting mechanism, semicolumn block body＜9〉and the governor motion of regulating block body and filament mouth distance form.Semicolumn block body＜9 〉, the fit with nozzle structure forms asymmetrical bias current field stable, at a high speed, guarantees the textured yarn quality to greatest extent, and control the seal wire direction with it that semicylinder is easy to process, is easy to spinning-in operation.The position of core filament mouth and distance behind block body and the nozzle are adjusted move left and right respectively and are moved up and down by block body set screw＜17〉and screw＜21 〉, and be fixed on housing＜10〉and the guide rail＜20 〉.Block body can be swung significantly around rocking pin＜19 〉, stablizes the position of its swing by spring bearer plate＜18 〉.Spring bearer plate also is fixing by block body set screw＜17 〉.

Spacing for core before the adjusting nozzle and back core, form the field of turbulent flow state so that cooperate the semicolumn block body to adjust compressed air, also to make the compressed-air actuated throttle orifice of feeding＜13〉become 0 degree or 180 degree configurations with filament mouth wire vent direction simultaneously, so processing chute＜A〉on housing, the front end of core before nozzle＜12〉is fixed with sliding pin＜14 〉, sliding pin can only be slided in chute, can not rotate, then core also just can not rotate thereupon move left and right before the nozzle.The front end face of core is made convex shoulder＜B〉before the nozzle, and convex shoulder is slidingly matched with the screw lid＜16〉that has scale, and in screw lid is threaded to promotes convex shoulder and makes that core and back core just contact before the nozzle, and the gap is zero, and scale is " 0 " at this moment.When the screw lid reverse rotation to needed gap, scale value is the distance between the core and back core before the nozzle.Core does not rotate before this adjustment process nozzle, but under compressed-air actuated effect, convex shoulder＜B〉is moved still be close to screw lid, reaches the purpose of adjusting.After adjusting,, prevent that screw lid is loosening to carry on the back mother＜15〉locking.

An embodiment of the present utility model is: the semicolumn block body, the length of cylinder is 20～25mm, radius is 12～13mm, core is 0.4～1.0mm with the distance of back core before the nozzle, the distance of block body and filament mouth is 0.5～1.5mm, the degree of depth of chute is 2.5mm, and the length of sliding pin is the cylindrical of 2mm.

The air-texturing jet of device semicolumn block body process easy to usely, is easy to maintenance, and amplitude of fluctuation is big, makes the chemical-fibres filaments repiece particularly convenient, makes the textured yarn steady quality, and minimizing ingot potential difference is different.The distance of core can be with scale ground to regulate at any time aborning before the nozzle.Through practical proof, this nozzle is applicable to the air deformation yarn of processing 300～4000 dtexs.Process velocity is generally 100～450 meter per seconds.
