Technical Field

The invention relates to a cloth dyeing machine structure, in particular to a nozzle device of an upward-moving cloth dyeing machine and a cloth storage groove structure thereof, which utilize multiple nozzles to reduce the liquid content of cloth to avoid the creasing of the cloth and greatly reduce the bath ratio by means of the angle drop of a slide type cloth storage groove.

Background

The dyeing and finishing industry belongs to the industries with high energy consumption, high water consumption and high pollution, so that how to actively and effectively save energy and reduce emission is a serious and urgent subject; especially, a large amount of water and steam are consumed in the cloth dyeing process, so that how to reduce the bath ratio of the cloth dyeing machine, namely, the water consumption required in cloth dyeing becomes the most core problem to be solved in the dyeing and finishing industry.

The cloth dyeing machine used in the general dyeing and finishing factory mainly circulates the dye liquor and the cloth sprayed by the nozzle in the cloth storage tank to achieve the dyeing effect; the dyeing quality is about 70-80% of the dyeing quality depends on the efficacy of the nozzle, and the dip dyeing of the cloth by the cloth dyeing tank only accounts for about 20-30% of the effect, so that the importance of the nozzle to the dyeing machine is the same as that of an engine in an automobile; furthermore, the cloth has various types according to the quality and density, and the dyeing characteristics are different; therefore, the success or failure of cloth dyeing and the function of the nozzle are great factors.

The existing cloth dyeing machine can be roughly divided into an O-type cloth dyeing machine and a long cloth dyeing machine, as shown in fig. 1, which is a structural schematic diagram of the existing O-type cloth dyeing machine, a cloth storage tank 11 is formed in an O-type trunk 10, cloth 21 is bathed in dye liquor 22 contained in the cloth storage tank 11, and is ejected from a nozzle 13 by the driving of a cloth lifting wheel 12 to push the cloth 21 to pass through a cloth guide pipe 14 and then enter the cloth storage tank 11 formed in the trunk 10, and the cloth dyeing operation can be completed by repeated circulation. Wherein, the nozzle 13 uses a liquid flow/jet flow nozzle, the cloth 21 is easy to be piled and pressed at the bottom of the cloth storage tank 11 to generate wrinkles, and the bath ratio is larger and is between about 1:5 and 1: 8; secondly, the nozzle 13 also uses an aerosol type nozzle, the bath ratio can be greatly reduced to 1:2 to 1:4, but a large amount of electricity is consumed, and the defects of easy color and wrinkle are the biggest defects; in addition, the arrangement of an aerosol nozzle and an air flow nozzle on the front and rear sides of the cloth lifting wheel 12 has the advantages of low bath ratio and low power consumption, however, the bottom of the cloth 21 stack is prone to fine wrinkles, and the smoothness of the cloth 21 is poor.

Fig. 2A to 2B are schematic structural diagrams of a conventional long cloth dyeing machine, the mechanism of which is substantially the same as that of an O-type cloth dyeing machine, and the conventional long cloth dyeing machine includes an L-shaped trunk 10 forming a cloth storage tank 11, a cloth 21 being immersed in a dye solution 22 contained in the cloth storage tank 11, and being driven by a cloth lifting wheel 12, the cloth 21 being ejected from a nozzle 13 to be pushed through a cloth guide pipe 14 and then entering the cloth storage tank 11, and the operation of dyeing the cloth 21 being repeated and circulated. Compared with the O-shaped dyeing machine, the long dyeing machine has the advantages that the cloth 21 is not excessively extruded and crumpled in the cloth storage tank 11, but the bath ratio is 1:8 to 1:10, which is a disadvantage; furthermore, as shown in fig. 2A, the cloth guide 14 is disposed above the outer portion of the body 10, and the cloth guide 14 of fig. 2B is disposed at the upper edge of the inner portion of the body 10, the latter has the advantage that the temperature difference between the dye solution in the cloth guide 14 and the dye solution in the inner portion of the body 10 is reduced, which further contributes to the improvement of the dyeing quality of the cloth 21.

Fig. 3A to 3B are schematic diagrams showing a structure of a conventional cloth dyeing machine with a slide-type cloth storage tank, which includes an L-shaped trunk 10 forming a cloth storage tank 11, a cloth 21 being immersed in a dye solution 22 contained in the cloth storage tank 11, and being driven by a cloth lifting wheel 12 to be ejected from a nozzle 13 to push the cloth 21 to pass through a cloth guide tube 14 and then enter the cloth storage tank 11, so as to repeatedly and cyclically perform a dyeing operation on the cloth 21. Wherein, the cloth storage tank 11 comprises an upper cloth storage tank 111, an inclined sliding layer cloth storage tank 112 and a lower cloth storage tank 113, and the cloth storage tanks have different horizontal inclination angles alpha 1/alpha 2/alpha 3, and the bottom of the cloth storage tank 11 is provided with a porous screen 201 to separate the dye liquor 22 rapidly; the cloth guide pipe 14 in fig. 3B is provided at the upper edge of the inside of the body 10; moreover, compared with the prior long cloth dyeing machine, the cloth dyeing machine adopting the slide type cloth storage groove has slightly improved bath ratio of about 1:4 to 1: 6; when the nozzle 13 adopts an aerosol nozzle, the bath ratio is better; however, the aerosol nozzle makes the cloth easily rub against the wall of the cloth guide tube 14, especially heavy cloth, and the cloth is more likely to be entangled.

The inventor is in the field of cloth dyeing machine manufacture for a long time, and the advantages and disadvantages derived from various configurations of the carcass, the cloth storage tank, the cloth guide pipe and the nozzle are found in the chest; therefore, the fabric dyeing machine needs to save energy and reduce emission, and can solve the problem of wrinkling of the fabric on the premise of effectively reducing the bath ratio and meeting the dyeing characteristics of different fabrics, which is the idea of the inventor and is in urgent need.

The invention mainly aims to provide a cloth dyeing machine structure capable of achieving a low bath ratio so as to meet the benefits of energy conservation and emission reduction.

Another objective of the present invention is to provide a method for effectively solving the problem of cloth wrinkling caused by cloth dyeing, so as to improve the quality of dyed cloth.

It is still another object of the present invention to provide a cloth dyeing machine structure that can select different nozzle types and different cloth guide tube configurations according to different cloth materials, thickness, batch size and dye liquor characteristics.

In order to achieve the purpose, the technical means adopted by the invention is as follows:

a cloth lifting wheel is arranged at the head end of the trunk body, and a liquid collecting pipeline is arranged at the lowest position of the bottom of the trunk body;

a slide type cloth storage groove, which comprises an upper layer cloth storage groove, an inclined sliding layer cloth storage groove and a lower layer cloth storage groove, wherein the upper layer cloth storage groove, the inclined sliding layer cloth storage groove and the lower layer cloth storage groove are respectively coated in the trunk body, have different horizontal inclination angles, and are sequentially and mutually connected to the lower end of the head of the trunk body from the tail of the trunk body, and the bottoms of the respective cloth storage grooves are provided with a multi-pore device so as to quickly separate dye liquor;

a first nozzle is arranged at the front end of the cloth lifting wheel, and a second nozzle is arranged at the rear end of the cloth lifting wheel and is used for spraying dye liquor on the cloth;

an upward-moving cloth guide tube, which is arranged above the slide-type cloth storage groove and is connected to the cloth inlet of the upper-layer cloth storage groove from the second nozzle to form a loop for upward-moving type circular dyeing of the cloth;

a cloth liquid separator installed at the tail end of the cloth guide pipe for separating dye liquid not adsorbed on the cloth;

an air flow type nozzle which is arranged at the rear end of the cloth-liquid separating device and is used for guiding cloth into the slide type cloth storage groove;

thus, when the cloth passes through the cloth lifting wheel, the first nozzle reduces the generation of straight crease marks, the second nozzle performs penetration dyeing on the cloth, and the cloth liquid separator and the airflow nozzle guide the cloth into the slide type cloth storage groove after reducing the adhesion of the dyeing liquid to the cloth; the cloth with reduced liquid content slides in a loose state by virtue of the structure that the slide-type cloth storage groove is inclined downwards, so that the cloth can be prevented from being wrinkled due to extrusion; meanwhile, the dye liquor which is not adsorbed on the cloth flows into the liquor collecting pipeline rapidly by virtue of the porous device and the fall between the upper and lower layer cloth storage tanks, thereby greatly reducing the bath ratio.

Wherein, the horizontal inclination angle of this upper strata cloth storage groove is between 1 ~ 10 degrees, and the horizontal inclination angle of this oblique sliding layer cloth storage groove is between 5 ~ 35 degrees, and the central circular arc radius of the body of cladding is ≧ 700mm, and the horizontal inclination angle of this lower floor cloth storage groove is between 1 ~ 10 degrees, and the central circular arc radius of the body of cladding is ≧ 600 mm.

Wherein, the upper-walking cloth guide pipe is arranged at the upper part of the outer part of the trunk body or at the upper edge of the inner part of the trunk body.

Wherein the first nozzle is a spray ring or an aerosol nozzle and the second nozzle is an overflow/jet nozzle or a throttling nozzle.

Thus, the first nozzle sprays the dye liquor on the cloth, so that the linear crease can be reduced when the cloth passes through the cloth lifting wheel; the second nozzle is used for carrying out permeation dyeing on the cloth and enabling the cloth to quickly enter the upper-walking cloth guide pipe; the cloth liquid separator separates the cloth in the upper-walking cloth guide pipe from the dye liquor and directly guides the separated dye liquor into the liquor collecting pipeline; the airflow type nozzle guides the cloth into the slide type cloth storage groove by pressurized air, and the cloth is enabled to have kinetic energy to slide forwards in a stacking way; in short, the nozzle device comprising the first/second nozzles, the cloth-liquid separator and the air-stream nozzle not only pushes the cloth to perform the circular dyeing, but also further reduces the liquid content of the cloth before the cloth enters the slide-type cloth storage tank. The cloth with reduced liquid content can slide to the lower cloth storage groove quickly in a loose state by virtue of the downward inclined slide type cloth storage groove structure, so that the cloth can be prevented from wrinkling along with the extrusion of the dye liquor; meanwhile, the dye liquor which is not adsorbed on the cloth flows into the liquor collecting pipeline rapidly by virtue of the porous device and the fall between the upper and lower layer cloth storage tanks, thereby greatly reducing the bath ratio.

By means of the characteristics of the previous disclosure, the nozzle device and the cloth storage tank structure of the cloth dyeing machine have the following benefits:

(1) the invention uses the fall between the upper and lower cloth storage tanks in the slide-ladder type cloth storage tank structure and the multi-hole device arranged at the bottom of the cloth storage tank, so that the dye liquor which is not adsorbed on the cloth can be quickly separated from the cloth and flows into the liquid collecting pipeline, thereby greatly reducing the bath ratio.

(2) In the nozzle device, besides the first nozzle and the second nozzle are used for pushing the cloth to be circularly dyed, the liquid separator and the air flow type nozzle are further arranged for reducing the liquid content of the cloth and enabling the cloth to enter the slide type cloth storage groove, and the cloth can rapidly slide to the lower cloth storage groove in a loose state, so that the cloth can be prevented from being wrinkled due to extrusion of a large amount of dye liquid.

(3) The first nozzle comprises any type of spray cloth ring and aerosol type nozzle, and the second nozzle comprises any type of overflow/jet type nozzle and throttle type nozzle; therefore, different nozzle forms can be selected according to different cloth materials, thicknesses, batches and dye liquor characteristics so as to achieve the best cloth dyeing quality.

Detailed Description

First, please refer to fig. 4, which is a schematic view of a nozzle device and a cloth storage tank structure of a cloth dyeing machine according to a first embodiment of the present invention, comprising: an L-shaped trunk 10, the head end of which is provided with a cloth lifting wheel 12, and the lowest part of the bottom of which is provided with a liquid collecting pipeline 15; a slide-type cloth storage tank 11, which comprises an upper cloth storage tank 111, an inclined sliding layer cloth storage tank 112, and a lower cloth storage tank 113, which are respectively coated in the L-shaped trunk 10, have different horizontal inclination angles α 1/α 2/α 3, and are sequentially connected to the lower end of the machine head from the tail of the L-shaped trunk 10, and the bottoms of the respective cloth storage tanks 11 are provided with a multi-aperture device 20; a first nozzle 31 and a second nozzle 34 are respectively disposed at the front and rear ends of the cloth lifting wheel 12; an upward-moving cloth guide tube 14, which is disposed above the slide-type cloth storage tank and is connected to the cloth inlet of the upper-layer cloth storage tank 111 through the second nozzle 34 to form a loop for upward-moving circular dyeing of the cloth 21; a liquid-liquid separator 38 installed at the tail end of the cloth guide pipe 14; an air flow nozzle 39 is installed at the rear end of the liquid-distributing separator 38.

Fig. 5 is a schematic view of a second embodiment of the nozzle device and the cloth storage tank structure of the cloth dyeing machine of the present invention, wherein the upper run cloth guide 14 is disposed at the upper edge of the inside of the L-shaped trunk 10, which is advantageous in that the difference between the dye liquor temperature inside the upper run cloth guide 14 and the dye liquor temperature inside the L-shaped trunk 10 is reduced, which is helpful for improving the dyeing quality of the cloth 21. In the invention, the horizontal inclination angle alpha 1 of the upper layer cloth storage groove 111 is between 1 and 10 degrees, the horizontal inclination angle alpha 2 of the inclined sliding layer cloth storage groove 112 is between 5 and 35 degrees, the central arc R of the coated trunk body is not less than 700mm, the horizontal inclination angle alpha 3 of the lower layer cloth storage groove 113 is between 1 and 10 degrees, and the central arc R of the coated trunk body is not less than 600 mm; the invention forms a slide-type cloth storage groove 11 structure by different inclination angles alpha 1/alpha 2/alpha 3, dye liquor which is not adsorbed on cloth flows into the lower layer cloth storage groove 113 along the height drop of the upper layer/lower layer cloth storage groove 111/113, so that the dye liquor is reduced to stay in the upper layer/inclined sliding layer cloth storage groove 111/112, and the water consumption is greatly reduced; furthermore, the horizontal inclination angle α 1/α 3 of the upper cloth storage tank 111 and the lower cloth storage tank 113 is smaller, so that the cloth can slide into the lower cloth storage tank 113 by virtue of the larger horizontal inclination angle α 2 of the inclined sliding layer cloth storage tank 112, and the cloth is not squeezed to generate wrinkles, thereby greatly improving the cloth dyeing quality.

The porous device 20 of the present invention is installed in the slide-type cloth storage tank 10, as shown in fig. 6A, and includes: an upper porous device 201 disposed at the bottom of the upper cloth storage tank 111, a slant sliding porous device 202 disposed at the bottom of the slant sliding cloth storage tank 112, a lower porous device 203 disposed at the bottom of the lower cloth storage tank 113 and having a horizontal inclination angle β 1/β 2/β 3 respectively corresponding to the horizontal inclination angle α 1/α 2/α 3 of the slide type cloth storage tank 11; basically, during the dyeing process, the cloth moves above the porous device 20 in sequence, wherein the dye solution not adsorbed on the cloth is separated by the contact pressure of the cloth and the porous device 20 and flows into the lower part of the porous device 20 through the pores thereof, and the dye solution can flow into the liquid collecting pipeline 15 rapidly, so the arrangement of the porous device 20 can theoretically improve the use efficiency of the dye solution circulation operation and effectively reduce the use amount of the dye solution. Furthermore, the porous device 20 includes any one of a porous mesh plate 26, a Teflon tube row 27, and a Teflon tube inner mesh 28; the structure of the porous screen 26 is shown in FIG. 6B, and the cross section thereof has a plurality of meshes 261, so that the dyeing liquid can rapidly flow into the lower part of the porous screen 26; the structure of the teflon tube row 27 is shown in fig. 6C, which is formed by co-axially and parallelly weaving a plurality of teflon tubes 271 and the slide-type cloth storage tank 10, gaps 272 are formed between the teflon tubes 271, so that the dye solution can rapidly flow into the lower part of the teflon tube row 27, and the cloth can slide on the teflon tube row 27 more easily due to the smooth surface of the teflon tubes 271; the structure of the teflon inner mesh 28 is shown in fig. 6D, wherein a plurality of teflon tubes 271 are assembled and woven on the porous mesh plate 26, so that the dye solution can rapidly pass through the gaps 272 and the meshes 261, and the cloth can easily slide on the teflon inner mesh 28 due to the smooth surface.

The first nozzle 31 of the present invention is arranged at the front end of the cloth lifting wheel 12, and aims to spray the dye liquor on the cloth, so that the generation of linear crease can be reduced when the cloth passes through the cloth lifting wheel 12; the type of the first nozzle 31 can be one of a spray cloth ring or an aerosol nozzle according to the characteristics of the cloth; FIG. 7A shows a structure of a spraying cloth ring 32, which has a liquid guiding tube 321 and a return tube 322 on its outer edge, and a plurality of spraying holes 323 on its inner edge, so that when cloth passes through the spraying cloth ring, the dye solution will be sprayed onto the cloth from the spraying holes 323; fig. 7B shows a structure of the gas mist type nozzle 33, which sucks gas and dye solution simultaneously by the pressure generated by the fluid to mix them, so that the dye solution forms a gas mist shape when being injected into the nozzle holder, and the sufficient amount of the dye solution is supplied to the nozzle, thereby achieving the effects of reducing the bath ratio and saving energy.

The second nozzle 34 of the present invention is disposed at the rear end of the cloth lifting wheel 12, and is used for performing the penetrating dyeing of the cloth and reducing the friction between the cloth and the tube wall when the cloth rapidly enters the upward-moving type cloth guide tube 14, and the type of the second nozzle 34 may be selected from one of an overflow/jet type nozzle and a throttle type nozzle according to the characteristics of the cloth; when the piece of cloth is cotton, Rayon (Rayon), wool, linen, a/W, T/C, R/L and other cloth with high staple fiber content, the overflow type or jet type dyeing operation is usually adopted, and the structure of the jet type nozzle 35 and the overflow type nozzle 36 is shown in fig. 8A-8C, and the structure presents a waterfall-shaped (water curtain-shaped) liquid flow state with high flow and low jet pressure. Fig. 8B shows a jet nozzle 35, in which the water guide opening is circular, and the dye solution sprayed from the nozzle is in an inverted conical shape and intersects at a point, which makes the cloth string-like, so that a straight crease is easily formed, which is the most defective. Fig. 8C shows a spill nozzle 36, in which the water outlet is rectangular, and the water jet is linear (sheet-like) at the intersection, so that the cloth is less likely to be rope-like, but if a wide cloth is dyed, a linear crease is formed. When the dyed cloth is a cloth with high fiber content such as nylon, Polyester (Polyester), N/T, T/C, T/R, R/T, N/C, etc., a throttling dyeing operation is usually adopted, and fig. 8D shows the structure of a throttling nozzle 37, which presents a high-flow-rate and high-pressure jet-type water-column-shaped liquid flow state.

FIG. 9 shows the structure of the liquid-liquid separator 38 and the air flow nozzle 39; the cloth-liquid separator 38 is installed at the tail end of the upper cloth guiding pipe 14 for separating the cloth in the upper cloth guiding pipe 14 from the dye solution and directly guiding the separated dye solution into the liquid collecting pipe 15; the bottom edge of the cloth-liquid separator 38 is provided with a plurality of flow holes 381 and a flow guide tube 382, since the second nozzle 34 sprays the dye liquid at high pressure to drive the cloth to circulate, part of the dye liquid permeates into the cloth in the upper run cloth guide tube 14, and most of the dye liquid which is not attached to the cloth runs along with the cloth, when the dye liquid flows through the cloth-liquid separator 38, the gravity will make the dye liquid fall into the plurality of flow holes 381 and the flow guide tube 382 and further be guided into the liquid collecting tube 15; the cloth will thus assume a relatively relaxed state after passing through the liquid-liquid separator 38. The air flow type nozzle 39 is installed at the rear end of the cloth liquid separator 38, and since the cloth passes through the cloth liquid separator 38 and the kinetic energy is reduced, in order to allow the cloth to be quickly and circularly dyed, the air flow type nozzle 39 is required to guide the cloth into the slide type cloth storage tank 11 by the pressurized air and to allow the cloth to be stacked and slid forward with kinetic energy.

The nozzle device of the present invention comprises a first nozzle 31, a second nozzle 34, a cloth-liquid separator 38, and an air-flowing nozzle 39, and has the main function of reducing the liquid content of the cloth before the cloth enters the slide-type cloth storage tank, in addition to pushing the cloth to perform the circular dyeing. The cloth with reduced liquid content can slide to the lower cloth storage groove quickly in a loose state by virtue of the downward inclined slide type cloth storage groove structure, so that the cloth can be prevented from wrinkling along with the extrusion of the dye liquor; meanwhile, the dye liquor which is not adsorbed on the cloth flows into the liquor collecting pipeline rapidly by virtue of the porous device and the fall between the upper and lower layer cloth storage tanks, thereby greatly reducing the bath ratio.

The invention utilizes the drop height between the upper and lower cloth storage tanks 111/113 in the structure of the slide-type cloth storage tank 11 and the porous device 20 arranged at the bottom of the tank, so that the dye liquor which is not adsorbed on the cloth can be quickly separated from the cloth and flows into the liquid collecting pipeline 15, thereby greatly reducing the bath ratio. Next, in the nozzle device of the present invention, in addition to using the first/second nozzle 31/34 to push the cloth for circular dyeing, a cloth liquid separator 38 and an air flow nozzle 39 are further installed to reduce the liquid content of the cloth and make the cloth enter the slide-type cloth storage tank 11, so that the cloth slides rapidly toward the lower cloth storage tank 113 in a loose state, thereby preventing the cloth from being wrinkled due to the squeezing of a large amount of dye. Furthermore, the first nozzle 31 of the present invention includes any type of spray ring 32 and aerosol nozzle 33, and the second nozzle 34 includes any type of jet/flood nozzle 35/36 and throttle nozzle 37; therefore, different nozzle forms can be selected according to different cloth materials, thicknesses, batches and dye liquor characteristics so as to achieve the best cloth dyeing quality.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
