Description

Technical Field

[0001] The present application relates to the technical field of dyeing equipment, and in particular to dyeing equipment with high dyeing stability and a dyeing process thereof. Background Art

[0002] In the production and processing of fabrics, it is often necessary to use dyeing equipment to color the fabrics so that the fabrics present a specific color to meet people's daily use needs.

[0003] Most existing dyeing equipment includes a traction device, a dyeing device and a color fixing device, wherein the traction device and the color fixing device are respectively arranged on opposite sides of the dyeing device, and the dyeing device is mostly a dye vat, the inner cavity of which is loaded with dyes for soaking and coloring the fabric. The traction device grabs the fabric and allows the fabric to enter the dye vat for dyeing. Most color fixing devices are heat drying machines, which heat dry the dyed fabric to help fix the color of the fabric.

[0004] However, the dyeing method of the fabric is to simply immerse it in the dye solution, but there is a problem that the dye solution is difficult to fully penetrate into the interior of the fabric, thereby greatly reducing the dyeing stability of the fabric, so there is room for improvement. Summary of the invention

[0005] In order to improve the problem that the dyeing solution is difficult to fully penetrate into the interior of the fabric, the present application provides a dyeing device and a dyeing process with high dyeing stability.

[0006] In the first aspect, the dyeing equipment with high dyeing stability provided by the present application adopts the following technical solution:

[0007] A dyeing device with high dyeing stability comprises a spray-dyeing device, a pressure-dyeing device and an immersion-dyeing device; the spray-dyeing device comprises a liquid-tracing bottom box and two groups of spray-dyeing mechanisms, the two groups of spray-dyeing mechanisms are relatively arranged above the liquid-tracing bottom box, and a spray-dyeing area for allowing fabrics to pass through and spray-dyeing the fabrics is formed between the two groups of spray-dyeing mechanisms; the pressure-dyeing device comprises a bottom supporting mechanism and a top pressing mechanism, the top pressing mechanism is arranged on the liquid-tracing bottom box through the bottom supporting mechanism, so as to perform pressure-dyeing treatment on the fabrics; the immersion-dyeing device comprises an impregnation box, the impregnation box is arranged on one side of the liquid-tracing bottom box, and the inner cavity of the impregnation box is used to fill dye liquid, so as to perform immersion-dyeing treatment on the fabrics.

[0008] By adopting the above technical scheme, the fabric enters the spray dyeing area, and the spray dyeing device sprays the fabric simultaneously through two groups of spray dyeing mechanisms to achieve preliminary dyeing of the fabric. The tracing liquid bottom box collects the dye liquid that cannot be absorbed by the fabric to reduce the waste of dye liquid and the pollution of the environment where the equipment is located; the pressure dyeing device presses the fabric after spray dyeing so that the dye liquid can fully penetrate into the inside of the fabric to improve the dyeing effect of the dye liquid on the fabric; the immersion dyeing device penetrates the fabric with the dye liquid to ensure the adhesion amount of the dye liquid on the fabric, which helps to ensure the dyeing stability of the fabric.

[0009] In a specific possible implementation scheme, each group of all the spray-dyeing mechanisms includes a dye duct, a frame-mounted side panel and a plurality of dye spray heads; the dye duct is arranged on the liquid tracing bottom box through the frame-mounted side panel, and the spray-dyeing area is located between the two dye ducts of the two groups of spray-dyeing mechanisms; all the dye spray heads are arranged on the dye spray pipe, and each of the dye spray heads is connected to the dye duct to spray the dye in the dye duct to the spray-dyeing area.

[0010] By adopting the above technical solution, the dye duct is installed on the liquid tracing bottom box through the rack-mounted side panel, and the dye nozzle sprays the dye in the dye duct onto the fabric to ensure the adhesion range and uniformity of the dye on the fabric, thereby helping to improve the dyeing stability of the fabric.

[0011] In a specific feasible implementation scheme, the bottom supporting mechanism includes a bottom supporting pile and a bottom supporting plate, and the bottom supporting plate is arranged on the liquid tracing bottom box through the bottom supporting pile; the top pressure mechanism includes a top pressure support plate, a plurality of top pressure rollers and a plurality of groups of top pressure springs, and the top pressure support plate is arranged on the bottom supporting plate through a plurality of top pressure springs, and the side wall of the top pressure support plate facing the bottom supporting plate is provided with a plurality of embedded pre-grooves, one of the top pressure rollers is rotatably arranged in the side wall of an embedded pre-groove, and each of the top pressure rollers is against the bottom supporting plate.

[0012] By adopting the above technical scheme, the bottom supporting plate is installed on the liquid tracing bottom box through the bottom supporting pile to receive the fabric after spray dyeing, and the top pressure supporting plate is installed on the bottom supporting plate through the top pressure spring, so that the top pressure roller presses the fabric against the bottom supporting plate. As the fabric moves, the top pressure roller rotates following the displacement of the fabric while pressing the fabric so that the dye on the fabric can be fully infiltrated into the inside of the fabric, so as to improve the adhesion firmness of the dye on the fabric; in addition, the top pressure roller can also squeeze out the dye that is difficult to absorb on the fabric, so that the fabric still has the ability to absorb new dye for coloring in subsequent steps, and by squeezing and re-absorbing the dye, it helps to improve the color fastness of the fabric to the dye absorption, thereby ensuring the dyeing stability of the fabric.

[0013] In a specific feasible implementation scheme, the bottom supporting mechanism also includes a push plate member, a wing connecting plate and a fixed connection assembly, the wing connecting plate is arranged on the top pressure support plate, the push plate member is passed through the bottom supporting plate, and the output end of the push plate member is connected to the top pressure support plate through a fixed connection assembly.

[0014] By adopting the above technical solution, after the output end of the push plate is connected to the wing connecting plate through a fixed connection component, when the output end of the push plate is in a contracted state, the top pressure roller abuts the fabric against the bottom supporting plate to perform pressure dyeing treatment on the fabric; when the output end of the push plate is extended outward, the top pressure support plate is displaced in the direction away from the bottom supporting plate, thereby facilitating the fabric to enter or move away from between the top pressure roller and the bottom supporting plate.

[0015] In a specific possible implementation scheme, the fixing assembly includes a contact plate and a locking bolt, the contact plate is arranged on the output end of the push plate, the contact plate is abutted against the wing connecting plate, and the contact plate is connected to the wing connecting plate through the locking bolt.

[0016] By adopting the above technical solution, the contact plate increases the contact area between the output end of the push plate and the wing connecting plate, and the locking bolt fixes the contact plate and the wing connecting plate, so that the output end of the push plate and the side wing plate can be quickly connected. At the same time, it is convenient for the operator to remove the connection structure between the output end of the push plate and the side wing plate, so that the operator can inspect and replace the equipment.

[0017] In a specific possible implementation scheme, the dyeing device also includes multiple groups of guiding rollers and multiple groups of guide mechanisms; all of the guiding rollers are arranged at intervals in the side wall of the impregnation box, and every two groups of guiding rollers form an auxiliary impregnation area in the side wall of the impregnation box; all of the guide mechanisms are arranged at intervals in the side wall of the impregnation box, and every two groups of guide mechanisms are relatively arranged in an auxiliary impregnation area to assist the dye liquid in impregnating the fabric.

[0018] By adopting the above technical scheme, the two guiding rollers of each auxiliary impregnation area are respectively located at the two ends of the height direction of the impregnation box, so that the fabric entering the inner cavity of the impregnation box moves forward in a serpentine posture along the length direction of the impregnation box, thereby increasing the impregnation time and travel distance of the fabric in the impregnation box, and ensuring the adhesion amount and adhesion effect of the dye solution on the fabric; the guide mechanism disturbs the dye solution in the impregnation box, so that the dye solution flows toward the fabric evenly and frequently, so as to improve the dyeing uniformity and stability of the fabric.

[0019] In a specific possible implementation scheme, each of the guide mechanisms includes a guide motor, a guide column and a plurality of guide blades; the guide motor is arranged in the side wall of the infiltration box, the guide column is arranged on the output end of the guide motor, and all the guide blades are arranged on the guide column at intervals.

[0020] By adopting the above technical solution, the guide motor rotates the output end to make the guide column drive all the guide blades to rotate, and then the dye liquid is disturbed by the guide blades, thereby accelerating the flow speed of the dye liquid in the impregnation box, and making the dye liquid continue to flow to the fabric at a high frequency to fully impregnate the fabric, thereby improving the adhesion amount of the dye liquid on the fabric and the impregnation effect.

[0021] In a specific possible implementation mode, a plurality of upstream flow channels are arranged on each guide vane, and the upstream flow channels located on opposite sides of the guide vane are staggered and distributed on the guide vane.

[0022] By adopting the above technical scheme, the upstream flow channel increases the amount of dye liquid that can be disturbed by a single guide blade, thereby increasing the amount of dye liquid attached to the fabric. When the fabric passes through multiple auxiliary immersion areas, the frequency of dye liquid adhesion to the fabric is increased, which helps to improve the dyeing stability of the fabric. In addition, the upstream flow channel can make the dye liquid flow to the fabric evenly and frequently through diversion, thereby reducing the phenomenon of uneven dyeing caused by concentrated adhesion of the dye liquid to the fabric.

[0023] In a second aspect, the present application also discloses a dyeing process of a dyeing device with high dyeing stability, and the dyeing process includes the following dyeing steps:

[0024] Spray dyeing: The fabric to be dyed passes through the spray dyeing area, and two sets of spray dyeing mechanisms spray dye on the fabric on opposite sides of the fabric at the same time to perform the initial dyeing of the fabric;

[0025] Pressure dyeing: The fabric after spray dyeing passes through the bottom support mechanism and the top pressure mechanism. The top pressure mechanism presses the fabric on the bottom support mechanism to make the dye enter the interior of the fabric.

[0026] Dip dyeing: The fabric after pressure dyeing enters the dipping box, and the dye liquid in the dipping box dips the fabric to dye the fabric again.

[0027] By adopting the above technical solution, operators can dye fabrics efficiently, and the dyed fabrics have the characteristics of uniform dyeing and high dyeing stability.

[0028] In summary, this application has the following beneficial technical effects:

[0029] 1. The fabric is preliminarily dyed by the spray dyeing device, and the pressing dyeing device presses the fabric to fully infiltrate the dye liquid on the fabric into the fabric to improve the firmness of the fabric after coloring; the impregnation device impregnates the fabric through the impregnation box, so that the fabric can achieve the effect of firm coloring and high dyeing stability after multiple dyeing;

[0030] 2. The guiding roller increases the distance and dyeing time of the fabric in the impregnation box, so that the fabric can be fully immersed in the dye liquid for dyeing; the guide motor drives the guide column to rotate, so that the guide blades disturb the dye liquid in the impregnation box, so that the dye liquid flows to the fabric at a high frequency and regularly, which helps to ensure the dyeing stability of the fabric.

[0038] The embodiments of the present application disclose a dyeing device with high dyeing stability.

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] Reference Figure 1The dyeing equipment with high dyeing stability includes a spray-dyeing device 1, a pressure-dyeing device 2 and an immersion-dyeing device 3. Among them, the spray-dyeing device 1 and the immersion-dyeing device 3 are respectively arranged on opposite sides of the pressure-dyeing device 2. The fabric to be dyed migrates through the traction device, and passes through the spray-dyeing device 1, the pressure-dyeing device 2 and the immersion-dyeing device 3 in sequence. The spray-dyeing device 1 is used to spray the dye on the fabric to perform the initial dyeing of the fabric. The pressure-dyeing device 2 presses the fabric so that the dye sprayed on the fabric fully penetrates into the inside of the fabric, and the dye that cannot be absorbed or infiltrated on the fabric is separated from the fabric. The immersion-dyeing device 3 infiltrates the fabric with the dye to dye the fabric again. This process improves the wetting firmness of the dye on the fabric by dyeing the fabric multiple times, which helps to ensure the dyeing stability of the fabric.

[0041] Reference Figure 1 and Figure 2 The spray dyeing device 1 comprises a liquid tracing bottom box 11 and two sets of spray dyeing mechanisms 12, wherein the liquid tracing bottom box 11 is fixed to the ground by bolts. Each set of spray dyeing mechanisms 12 comprises a dyeing liquid conduit 121, a frame-mounted side plate 122 and a plurality of dyeing liquid nozzles 123, wherein one end of the frame-mounted side plate 122 in the length direction is welded to the inner bottom wall of the liquid tracing bottom box 11, and the dyeing liquid conduit 121 is welded to one end of the frame-mounted side plate 122 in the horizontal direction away from the liquid tracing bottom box 11, so that the dyeing liquid conduit 121 is suspended and mounted above the side liquid bottom box. In this embodiment, the two dye liquid ducts 121 of the two groups of spray-dyeing mechanisms 12 are relatively distributed above the liquid tracing bottom box 11 in the vertical direction, the dye liquid duct 121 of one group of spray-dyeing mechanisms 12 is located at a higher position than the dye liquid duct 121 of the other group of spray-dyeing mechanisms 12, and a spray-dyeing area 124 is formed between the two dye liquid ducts 121 of the two groups of spray-dyeing mechanisms 12, and the spray-dyeing area 124 is used for fabrics to pass through.

[0042] Reference Figure 2 , all dye spray heads 123 are respectively arranged on the two dye ducts 121 of the two groups of spraying mechanisms 12, and all dye spray heads 123 located on the same dye duct 121 are evenly and spacedly distributed along the length direction of the dye duct 121, and each dye spray head 123 is connected to the dye duct 121 where it is installed. When the fabric enters and passes through the spraying area 124, the dye spray head 123 sprays the dye in the dye duct 121 evenly, so as to perform spraying operation on both sides of the fabric thickness direction at the same time, so that the fabric is preliminarily dyed. The excess dye sprayed by the dye spray head 123 and the dye seeping from the fabric fall into the inner cavity of the liquid tracing bottom box 11 for unified collection, thereby reducing the waste of dye and the phenomenon of pollution of the equipment location.

[0043] Reference Figure 1 and Figure 3The dyeing device 2 includes a bottom supporting mechanism 21 and a top pressing mechanism 22, wherein the bottom supporting mechanism 21 further includes a bottom supporting pile 211 and a bottom supporting support plate 212. The end of the bottom supporting pile 211 close to the liquid tracing bottom box 11 is welded to the side wall of the liquid tracing bottom box 11, and the bottom supporting pile 211 is welded to the end of the bottom supporting pile 211 away from the liquid tracing bottom box 11.

[0044] Reference Figure 3 The pressing mechanism 22 includes a pressing support plate 221, a plurality of pressing rollers 222 and a plurality of pressing springs 223, wherein the pressing springs 223 may be steel compression springs. One end of all compression springs in the length direction is welded to the side wall of the pressing support plate 221 facing the bottom support plate 212, and all compression springs are divided into two rows and are respectively located at both ends of the length direction of the pressing support plate 221. The other ends of all pressing springs 223 in the length direction are welded to the top wall of the bottom support plate 212, so that the pressing support plate 221 is suspended above the bottom support plate 212.

[0045] Reference Figure 3 The side wall of the top pressure support plate 221 facing the bottom support plate 212 is provided with a plurality of embedded pre-grooves 2211 at intervals, and a top pressure roller 222 is rotatably disposed in the side wall of one of the embedded pre-grooves 2211. In this embodiment, when the compression spring is in a free extension state, the side wall of the top pressure roller 222 abuts against the side wall of the bottom support plate 212 facing the top pressure support plate 221.

[0046] Reference Figure 3 In order to facilitate the fabric to pass between the bottom support plate 212 and the top pressure roller 222, the bottom support mechanism 21 further includes a push plate 213, a wing connecting plate 214 and a fixing assembly 215, wherein the fixing assembly 215 further includes a contact plate 2151 and a locking bolt 2152. In this embodiment, the push plate 213 can be an electric cylinder, the push plate 213 is penetrated and welded on the bottom support plate 212, the contact plate 2151 is welded on the output end of the push plate 213, and the outer circumference of the contact plate 2151 is greater than the outer diameter of the output end of the push plate 213.

[0047] Reference Figure 3 The wing connecting plate 214 is welded to both ends of the top pressure support plate 221 in the length direction. When the output end of the push plate 213 is in a contracted state, the contact plate 2151 contacts the wing connecting plate 214, and the outer circumference of the wing connecting plate 214 is larger than that of the contact plate 2151. The locking bolt 2152 passes through the contact plate 2151 and is screwed on the wing connecting plate 214, so that the contact plate 2151 and the wing connecting plate 214 are fixedly connected as a whole.

[0048] Reference Figure 3As the push plate 213 extends outward from the output end, the top pressure support plate 221 moves away from the bottom support plate 212, the top pressure spring 223 is stretched by the thrust, and the top pressure roller 222 and the bottom support plate 212 are fitted with a gap, so that the fabric enters the gap between the top pressure roller 222 and the bottom support plate 212. When the push plate 213 shrinks the output end, the top pressure roller 222 abuts the fabric against the bottom support plate 212. As the fabric is pulled by external force and displaced between the top pressure roller 222 and the bottom support plate 212, the top pressure roller 222 abuts against the fabric and the bottom support plate 212 while rotating to assist the fabric displacement. In this process, the fabric is pressed so that the dye can fully enter the interior of the fabric to ensure the firmness of the dye on the fabric. At the same time, the pressed fabric can squeeze out the dye that the fabric cannot absorb, so that the subsequent dye can fully infiltrate and color the fabric.

[0049] Reference Figure 1 and Figure 4 The dyeing device 3 includes an impregnation box 31, which is fixed to the ground by bolts and is located on one side of the bottom box 11 to receive the fabric after spray dyeing and pressure dyeing. In this embodiment, the inner cavity of the impregnation box 31 is used to load the dye liquid. After the fabric enters the inner cavity of the impregnation box 31, it is impregnated with the dye liquid to be dyed again, which helps to improve the color fastness of the dye liquid on the fabric and ensures the dyeing stability of the fabric.

[0050] Reference Figure 4 In order to improve the coloring stability of the fabric in the soaking box 31, the soaking and dyeing device 3 also includes a plurality of guide rollers 32. All guide rollers 32 are rotatably arranged in the side wall of the soaking box 31, and two adjacent guide rollers 32 are respectively located at the two ends of the height direction of the soaking box 31, and two adjacent guide rollers 32 form an auxiliary soaking area 33 in the inner cavity of the soaking box 31. In this embodiment, there can be three auxiliary soaking areas 33 in the inner cavity of an soaking box 31. After the fabric enters the inner cavity of the soaking box 31, it passes through the three auxiliary soaking areas 33 in sequence. Since the two guide rollers 32 in each auxiliary soaking area 33 are respectively located at the two ends of the height direction of the soaking box 31, the fabric is serpentinely distributed along the length direction of the soaking box 31. This process increases the travel distance and travel time of the fabric in the soaking box 31, which helps to fully soak the fabric in the soaking box 31 so as to fully color it, thereby ensuring the coloring stability of the fabric.

[0051] Reference Figure 4In order to make the dye liquid fully adhere to the surface of the fabric to color, the dyeing device 3 also includes a plurality of guide mechanisms 34, all of which are arranged in the side wall of the soaking box 31. In this embodiment, there are two guide mechanisms 34 in each auxiliary soaking area 33. When the fabric passes through the two guide rollers 32 in the same auxiliary soaking area 33, the two guide mechanisms 34 in the same auxiliary soaking area 33 are respectively located on both sides of the fabric thickness direction to disturb the dye liquid to flow toward the fabric, so that the dye liquid is fully attached to the fabric.

[0052] Reference Figure 4 and Figure 5 Each group of guide mechanisms 34 includes a guide motor 341, a guide column 342 and a plurality of guide blades 343, wherein the guide motor 341 may be a waterproof motor, which is fixed to the side wall of the infiltration box 31 by bolts, the guide column 342 is coaxially welded to the output end of the guide motor 341, and all the guide blades 343 are uniformly and spacedly welded to the outer peripheral wall of the guide column 342. The guide motor 341 rotates the output end to make the guide column 342 drive all the guide blades 343 to rotate, thereby making the dye liquid flow to the fabric, so as to increase the amount and efficiency of the dye liquid attached to the fabric.

[0053] Reference Figure 5 , a plurality of upstream channels 3431 are also provided on the guide blade 343. In the present embodiment, the upstream channels 3431 may be wavy channels. All upstream channels 3431 are evenly and spacedly distributed along the length direction of the guide blade 343, and the upstream channels 3431 located on both sides of the width direction of each guide blade 343 are staggered with each other. When the guide blade 343 rotates in the dye liquid with the guide column 342, the dye liquid is guided through the upstream channels 3431 to flow toward the fabric evenly and with frequency, so as to reduce the phenomenon of uneven dyeing due to the concentrated attachment of the dye liquid to the fabric. In addition, the staggered upstream channels 3431 can also increase the amount of dye liquid that can be disturbed by a single guide blade 343, increase the amount of dye liquid attached to the fabric, and then pass through the fabric through multiple auxiliary immersion areas 33, increase the frequency of dye liquid attachment to the fabric, and help improve the dyeing stability of the fabric.

[0054] The implementation principle of the dyeing device with high dyeing stability in the embodiment of the present application is as follows: when the fabric passes through the spray dyeing area 124, all the dye liquid nozzles 123 on the two dye liquid ducts 121 spray the dye liquid at the same time to perform spray dyeing operations on both sides of the fabric in the thickness direction.

[0055] The fabric after spraying dyeing enters between the top pressure roller 222 and the bottom support plate 212. The top pressure roller 222 presses the fabric against the bottom support plate 212 and rotates with the displacement of the fabric, thereby fully pressing the dye liquid into the fabric. At the same time, the dye liquid that cannot be absorbed by the fabric in time is pressed outward by the top pressure roller 222, so that the fabric has the ability to continue to absorb the dye liquid for coloring.

[0056] The fabric after pressure dyeing enters the inner cavity of the impregnation box 31, and multiple guide rollers 32 make the fabric move in a serpentine manner in the impregnation box 31, so as to increase the distance and time that the fabric travels in the dye liquid, and improve the adhesion effect of the dye liquid on the fabric. The guide motor 341 rotates the output end to make the guide column 342 drive the guide blade 343 to disturb the dye liquid, so that the dye liquid flows evenly to the fabric, so as to improve the dyeing effect of the dye liquid on the fabric and ensure the dyeing stability of the fabric.

[0057] The present application also discloses a dyeing process of a dyeing device with high dyeing stability, and the dyeing process includes the following dyeing steps:

[0058] Spray dyeing: The fabric to be dyed enters and passes through the spray dyeing area 124 through the traction device, and all the dye nozzles 123 on the two dye ducts 121 spray the dye at the same time, so that the dye is fully soaked on both sides of the fabric in the thickness direction, thereby achieving the initial dyeing of the fabric.

[0059] Pressure dyeing: The fabric after spray dyeing enters between the top pressure roller 222 and the bottom support plate 212. The top pressure roller 222 presses the fabric against the bottom support plate 212 while rotating automatically with the displacement of the fabric. In this process, the top pressure roller 222 presses the fabric against the bottom support plate 212, so that the dye absorbed by the fabric can fully penetrate into the interior of the fabric.

[0060] In addition, as the pressing roller 222 presses the fabric, the dye liquid that cannot be absorbed on the fabric is squeezed outward by the pressing roller 222, thereby enabling the fabric to continue to absorb the dye liquid for further coloring.

[0061] Dyeing: The fabric after pressure dyeing enters the impregnation box 31, and all the auxiliary impregnation areas 33 with guide rollers 32 make the fabric in the impregnation box 31 show a serpentine distribution trend to meander forward. This process increases the travel distance and time of the fabric in the dye solution, improves the adhesion effect of the dye solution on the fabric, and then allows the fabric to be fully impregnated with the dye solution for coloring.

[0062] In addition, the guide motor 341 rotates the output end to cause the guide column 342 to drive the guide blades 343 to disturb the dye liquid, so that the dye liquid can flow toward the fabric evenly and frequently, thereby increasing the amount and frequency of dye liquid adhesion on the fabric, thereby ensuring the dyeing effect of the dye liquid on the fabric, and helping to ensure the dyeing stability of the fabric.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
