The pulsed spray-painting system of a kind of dyeing machinery and control method thereof
Technical field
The present invention relates to dyeing machinery technical field, it is specifically related to pulsed spray-painting system and the control method thereof of a kind of dyeing machinery.
Background technology
Textile industry is the important industry of Chinese national economy, for a long time, textile industry is the development of national economy, solves that the people wear the clothes, great contribution has been made in the aspect such as foreign exchange earning, and has important status undoubtedly in this industry as the dyeing and finishing industry connecting bridge. Dyeing and finishing industry is textiles deep processing, precision work and the key putting forward added value, is the tie that textile fibres, former yarn, embryo cloth are processed between the finished product entering consumer goods market, plays the vital role promoting product common development.
Bath raio is an important index in dyeing course, and the size of bath raio directly reflects the quality of dyeing quality. Bath raio refers to the dye liquor of preparation and the mass ratio of pollutant when contaminating or exhaust dye dyeing. Production application is often used as the density of dye liquor as 1 process. Bath raio has dividing of size, if 1:20,1:30 is big bath raio; 1:3,1:5 is short liquor ratio. Bath raio, also known as liquid ratio, refers to yarn and the ratio of dye liquor weight. Such as textiles double centner dye liquor 1000 kilograms, then bath raio is 1:10. The shortcoming of tradition equipment for dyeing and finishing is that bath raio is big, current consumption big, process time length many with dye addictive etc. During actual production, spindle is under the state of saturation of drenched water, and dye liquor soaks half creel. Adopting the equipment for dyeing and finishing of ultralow bath ratio dyeing technology, its advantage mainly contains:
(1) dyestuff is saved. In dyeing course, the concentration of the fuel of same amount in different bath raio is different, and dye uptake when it reaches dyeing equilibrium is also different. When carrying out short liquor ratio dyeing when certain consumption dyestuff, in its dye liquor, the concentration of dyestuff is relatively large, dye strength on fabric fibre rises with the increase of dye strength in dye liquor, and dye strength decline remaining in dye liquor, decrease the quantity discharged of dyestuff in discarded dye liquor. Otherwise, bath raio is big, and the fuel concentration in dye liquor is relatively low, and dye strength when fabric fibre contaminates is also lower, thus adds the quantity discharged of dyestuff in useless dye liquor. Therefore, the size of bath raio can directly affect exhaustion rate and the degree of fixation of dyestuff, particularly for conventional reactive dyestuffs. The size of bath raio can directly affect the consumption of auxiliary agent, ionogen. When carrying out short liquor ratio dyeing, not only fabric obtains color depth, decreases the consumption of colour additive simultaneously, decreases the quantity discharged of sewage.
(2) reproducibility is good. Carrying out short liquor ratio when dyeing, the change of bath raio is relatively little, though dyestuff is different to the interdependence of bath raio, but due to bath raio little, the change of fabric dye uptake is little, and aberration is generally within acceptable scope, and namely the circulation ratio of short liquor ratio dyeing is relatively better.
(3) uniform dyeing property is good. During dyeing, the quality of level-dyeing property of fabric depends primarily on the circulation frequency of dye liquor. During dyeing, bath raio reduces, and the cycle index of dye liquor just increases. The circulation frequency of dye liquor is more big, and diffusion and the upper dye chance of dyestuff are just many, so that it may to improve the situation of local uneven dyeing.
(4) short liquor ratio dyeing water saving, energy-conservation. During dyeing, the consumption of water, electricity, steam is all relevant with bath raio, and the little then energy consumption of bath raio is low. Water system and multifunctional intellectual water wash system are washed by many provinces of short liquor ratio chromosome addition, have very significant water-saving result. Short liquor ratio staining technique has significant technical superiority in textile dyeing, heat transfer rate height, master cylinder water level be full of with drain time short, water saving, energy-conservation, greatly shorten dyeing cycle, increase turnout.
Short liquor ratio dyes not only good level-dyeing property, saves the consumption of dyestuff, auxiliary agent, ensure that the circulation ratio of dyeing, and more embodies feature efficient, energy saving standard. Therefore, short liquor ratio dyeing is the main developing direction of dyeing and finishing technique.
Summary of the invention

Embodiment
Below in conjunction with specific embodiment, the invention will be further described, but the protection of the present invention and enforcement are not limited to this, are pointed out that, if having below, part is not described especially in detail, is all that those skilled in the art can refer to prior art understanding or realize.
As shown in Fig. 1 ~ 6, a pulsed spray-painting system for dyeing machinery, mainly comprises flower and spills the parts such as jet pipe 1, nozzle component 2, dye liquor isocon 3, dye liquid pump 4, valve 5, jet pipe bracing frame 6, motor and wheel box 7, worm screw 8, worm gear 9, counting gear 10, sensor 11, power shaft 12.
Such as Fig. 4, described nozzle component 2 comprises star jet pipe 21, pipe core 22, pallet 23, and the spray orifice 24 that star jet pipe 21 upper surface is offered. Such as Fig. 5, described pipe core 22 is hollow cylindrical structure, and dye liquor outlet opening 221 has been offered on its surface; Such as Fig. 6, jet pipe 24 has been offered on a surface of described star jet pipe 21, and the symmetrical center line of star jet pipe is coaxial with pipe core 22, and pipe core 22 is positioned at star jet pipe inside; It is one right that described pallet 23 has, and is separately fixed at the two ends of star jet pipe 21, and pallet vertical is enclosed within pipe core 22 in pipe core axis.
Described nozzle component 2 is coaxially fixedly connected with power shaft 12 by pipe core 22 so that nozzle component 2 rotates along with power shaft 12; Power shaft 12 is fixedly connected with the centre hole of worm gear 9, thus can accept the power from worm gear 9; Exporting rotating speed and the moment of torsion of setting under the control that motor 5 omits in the central controller figure of dyeing machinery, the motion exported drives worm screw 8 to rotate; Worm screw 8 and worm gear 9 do gear motion, thus by transmission of power to worm gear. The other end of nozzle component 2, frame is on jet pipe bracing frame 6, and nozzle component can rotate freely motion.
The yarn or the fabric sleeve that carry out spray-painting are outside at nozzle component 2, owing to yarn or fabric have certain gravity, star jet pipe 21 surface of itself and nozzle component 2 has certain frictional force, and thus when nozzle component 2 is in rotary course, yarn or fabric also move thereupon.
Such as Fig. 2, arrow represents that dye liquor flows to, and dye liquor obtains power under the effect of dye liquid pump 4, and flows in dye liquor isocon 3, and the pipe core 21 and the flower that then enter nozzle component 2 respectively spill in jet pipe 1; Enter the dye liquor of pipe core 22, entered in star jet pipe 22 by the through hole on pipe core 21 surface, and in the rotary motion of nozzle component 22, spray to fabric by the spray orifice 24 on star jet pipe 21 surface; Flower spills and arranges valve 5 on jet pipe 1, enters, for controlling, the dye liquor that flower spills jet pipe; When valve 5 is opened, dye liquor spills, by flower, the through hole offered on jet pipe 1 surface and sprays to fabric.
Described nozzle component 2 and flower spill jet pipe 1 can arrange many covers simultaneously, usually can arrange 1 ~ 10 cover.
As a kind of example, during spray-painting, central controller according to waiting to contaminate the character of fabric, fabric is wound around thickness and the output pressure of coloration requirements setting dye liquid pump 4, thus control is by spray orifice on star jet pipe 21 24 and the dye liquor pressure spending the through hole spilling jet pipe 1, reach the pressure that control dye liquor penetrates fabric; The rotating speed of central controller controls motor 7, thus control the speed of rotation of nozzle component 2, reach the object of control fabric spray-painting concentration.
