[0002] Dyeing means dyeing with color, also known as coloring, which refers to using chemical or other methods to affect the substance itself to make it colored. When the fiber is immersed in a dye aqueous solution at a certain temperature, the dye moves from the water phase to the fiber. At this time, the amount of dye in the water gradually decreases. After a period of time, it reaches a state of equilibrium. This process is dyeing.

[0003] In the prior art, for dyeing of cloth, generally a single piece of cloth is immersed in dyeing liquid for dyeing.

Compared with the single-piece continuous dyeing in the prior art, the dripping loss of the dyeing liquid can be effectively reduced while ensuring the dyeing efficiency.

[0008] As a further improvement of the present application, multiple rows of fixed roll columns are arranged on the inner wall on the same side of the dyeing tank, and the axial lengths of the multiple rows of fixed roll columns gradually increase from top to bottom, and the ends of the fixed roll columns in the upper row are located on the side of the U-shaped groove on the fixed roll columns in the next row away from the center of the dyeing tank.

[0009] As a further improvement of the present application, during dyeing, the cloth to be dyed is wound together with the spacer cloth air cushion on a reel to form a sandwich cloth roll, and the axial length of the wound interlayer on the upper row of carrier rolls is greater than the axial length of the wound interlayer on the lower row of carrier rolls.

The water outlet of the micro water pump is fixed and communicated with the radial hollow bar through a flexible pipe.

[0011] As a further improvement of the present application, the outer end of the radial hollow bar extends to the outside of the outermost layer of the sandwich cloth roll, and the ends of the two radial hollow bars on the two fixed roll columns face oppositely.

[0012] As another improvement of the present application, a water pressure detection component is installed at one end of the radial hollow bar facing the interlayer cloth roll, and the water pressure detection component includes two hidden pressure strips respectively located on both sides of the multiple nozzles and a sensing bag fixedly connected between the two hidden pressure strips. The hidden pressure strip is a hollow structure, and a plurality of pressure sensors corresponding to the plurality of sensing bags are installed inside the hidden pressure strip.

[0013] As another improved supplement of the present application, the force sensing end of the pressure sensor faces the contact piece, the contact piece is an elastic sealing structure, and the sensing bag is a hollow elastic airbag structure bulging outward.

[0014] A method for dyeing cloth using a dyeing device for textile cloth processing comprises the following steps:

[0017] S3, pour dyeing liquid into the dyeing tank until the liquid level submerges all the interlayer cloth rolls, and the control center extracts the gas in the cloth spacer air cushion into the air storage cavity through the intelligent inflation and deflation component, so that the bulged cloth spacer air cushion is deflated, and the multiple layers of cloth in the interlayer cloth roll are relaxed, and there are gaps between each layer of cloth;

[0018] S4, then controlling the dye acceleration bars on both sides of the carrier roll to rotate around the fixed roll column, and starting the micro water pump at the same time, so that the dyeing liquid enters the dye acceleration bar and is sprayed toward the end surface of the interlayer cloth roll through multiple nozzles, and the sprayed dyeing liquid quickly enters the inner part of the interlayer cloth roll along the gap between each layer of cloth, thereby accelerating the penetration of the dyeing liquid into the cloth;

[0019] S5. The intelligent inflation and deflation components are continuously controlled to repeat the inflation and deflation process of the air cushion of the fabric separation sheet, so that each layer of fabric is continuously squeezed back and forth to achieve a full dyeing effect.

[0020] In summary, through the arrangement of multiple loading rolls, it is possible to put the cloth in a roll into a dyeing tank for immersion dyeing, wherein there is an interlayer between each layer of cloth on the loading roll, and the multi-layer cloth can be relaxed by adjusting the interlayer, and there is a gap between the two layers, so that the dyeing liquid can smoothly dye the inner layer of the cloth. Compared with the continuous dyeing of a single piece in the prior art, the dripping loss of the dyeing liquid can be effectively reduced while ensuring the dyeing efficiency; in addition, with the arrangement of the dye acceleration strip, the dyeing liquid can also be assisted to be sprayed toward the inside of the interlayer cloth roll, thereby accelerating the penetration of the dyeing liquid in the inner layer of the cloth, and at the same time, with the arrangement of the water pressure detection component, the spraying intensity of the dyeing liquid toward the cloth can also be monitored, thereby achieving targeted regulation, so that the dyeing effect of the rolled cloth is better and the efficiency is higher.

DETAILED DESCRIPTION

[0035] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0036] The first implementation method:

[0037] Figure 1and Figure 2 A dyeing device for textile fabric processing is shown, comprising a dyeing tank 1 with a control center and a base 21 located on one side of the dyeing tank 1, the upper end of the base 21 is connected to an L-shaped support rod 22 through an electric turntable, the lower end of the L-shaped support rod 22 away from the base 21 is fixedly connected to an electric push rod 23, the upper end cover of the dyeing tank 1 is provided with a tank cover 11, the tank cover 11 is fixedly connected to the electric push rod 23, and the upper end of the dyeing tank 1 is also fixedly connected to a plurality of evenly distributed exhaust pipes 12, which can be used to balance the air pressure inside and outside the dyeing tank 1.

[0038] like Figure 3 The front and rear inner walls of the dyeing tank 1 are fixedly connected with a plurality of opposite fixed coil columns 4, such as Figure 5 and Figure 6 A U-shaped groove 401 with an upward opening is cut on the fixed roll column 4, and a dye acceleration bar 5 is connected to the fixed roll column 4 through an electric rotating shaft. A material loading roll 3 is set between two opposite fixed roll columns 4, and the two ends of the material loading roll 3 are respectively located in the two U-shaped grooves 401. The dye acceleration bar 5 includes a rotating ring 51 connected to the outside of the fixed roll column 4 through an electric rotating shaft, a radial hollow bar 52 fixedly connected to the end of the rotating ring 51 away from the axis, and a plurality of nozzles 53 are installed on the nozzle 53. A plurality of micro water pumps are installed in the dyeing pool 1, and the water outlet of the micro water pump is connected to the fixed roll column 4 through an electric rotating shaft. The flexible tube is fixed and communicated with the radial hollow bar 52. When dyeing, the cloth is wound on the carrier roll 3, and then the carrier roll 3 is set between two fixed roll columns 4, so that the rolled cloth can be immersed in the dyeing liquid as a whole, and then the dyeing liquid can be sprayed into the cloth roll through a micro water pump, thereby accelerating the uniform contact between the multi-layer cloth and the dyeing liquid, thereby effectively ensuring the dyeing effect under this dyeing method. Compared with the dyeing method of immersing a single piece of cloth, it can not only ensure the dyeing efficiency, but also effectively and significantly reduce the loss of dyeing liquid.

[0039] like Figure 4 , multiple rows of fixed roll columns 4 are arranged on the inner wall of the same side of the dyeing tank 1, and the axial lengths of the multiple rows of fixed roll columns 4 gradually increase from top to bottom, and the ends of the fixed roll columns 4 in the upper row are located on the side of the U-shaped groove 401 on the fixed roll columns 4 in the lower row away from the center of the dyeing tank 1, so that when multiple loading rolls 3 are set up in the dyeing tank 1, the upper fixed roll columns 4 are not easy to block the lower fixed roll columns 4, which is convenient for the upper and lower rows of distributed dyeing of multiple rolls of cloth, and effectively ensures the dyeing efficiency; when dyeing, the cloth to be dyed is wound together with the cloth spacer air cushion 32 on the reel 31 to form a sandwich cloth roll, and the axial length of the winding interlayer on the upper row of loading rolls 3 is greater than the axial length of the winding interlayer on the lower row of loading rolls 3, so that cloths of different widths can be dyed synchronously in the dyeing tank 1, and can adapt to cloths of different sizes.

[0040] Correspondingly, the distance between the plurality of reels 31 is also shortened from top to bottom, and is exactly the distance between the inner walls of two opposite U-shaped grooves 401 .

[0041] The outer end of the radial hollow bar 52 extends to the outside of the outermost layer of the sandwich cloth roll, which effectively ensures that when the radial hollow bar 52 rotates with the rotating ring 51 to spray the dyeing liquid on the sandwich cloth roll, the ends of the sandwich cloth roll can be fully sprayed with the dyeing liquid, and the ends of the two radial hollow bars 52 on the two fixed roll columns 4 are in opposite directions. During dyeing, both of them spray the dyeing liquid toward the sandwich cloth. The misalignment of the two can reduce the influence of the relatively sprayed dyeing liquids on each other, make the dyeing liquid have a longer movement range inside each layer of the sandwich cloth roll, and achieve a better dyeing effect on the cloth.

[0042] like Figure 7 The material carrying reel 3 includes a reel 31 and a spacer air cushion 32 connected to the outer end of the reel 31, an air storage cavity 301 is excavated inside the reel 31, the spacer air cushion 32 includes an adaptive isolation layer 322 located outside the reel 31 and a positioning strip 321 fixedly connected to the end of the adaptive isolation layer 322, the positioning strip 321 is fixedly embedded in the reel 31, and a plurality of intelligent charging and discharging components 302 are also fixedly embedded in the reel 31, and the plurality of intelligent charging and discharging components 302 are fixedly connected to the positioning strip 321 and communicate with the air storage cavity 301 and the positioning strip 321, and the control center can control the adaptive isolation layer 322 through the intelligent charging and discharging components 302. Regarding the gas inside the separation layer 322, when winding, air is inflated into it to make the adaptive isolation layer 322 swell. At this time, after the cloth is wound, there is a certain space between the two adjacent layers of cloth due to the swollen adaptive isolation layer 322. When dyeing, the intelligent inflation and deflation component 302 is controlled to extract the gas in the adaptive isolation layer 322, that is, to deflate it. At this time, the adaptive isolation layer 322 gradually deflates and forms a sheet by swelling, and the thickness is greatly reduced. At this time, a gap is generated between the two adjacent layers of cloth, and the wound cloth is in a relaxed state, and the color-changing liquid enters, so that the cloth can still quickly and fully contact with the dyeing liquid for dyeing when it is wound.

[0043] In addition, it is worth noting that when unloading after dyeing, the box's adaptive isolation layer 322 can be inflated so that the air can squeeze the wound fabric and accelerate the dripping of the adsorbed dyeing liquid, thereby effectively avoiding excessive dyeing liquid being carried away from the dyeing tank 1 and dripping when unloading.

[0044] A method for dyeing cloth using a dyeing device for textile cloth processing comprises the following steps:

[0045] S1, such as Figure 8 In the figure, a represents a sandwich cloth roll, and b represents cloth. First, the cloth to be dyed is wound together with the spacer cloth air cushion 32 on the reel 31 to form a sandwich cloth roll. Before winding, the control center first inflates the spacer cloth air cushion 32 through the intelligent inflation and deflation component 302 to put the spacer cloth air cushion 32 in an inflated state, so that there is a sandwich of bulging spacer cloth air cushion 32 between each layer of cloth formed after winding;

[0046] S2, the control center controls the electric push rod 23 to shorten so that the pool cover 11 is separated from the dyeing pool 1, and then controls the L-shaped support rod 22 to rotate and drive the pool cover 11 away from the dyeing pool 1, so that the upper end of the dyeing pool 1 is opened, and then the material loading roll 3 with the interlayer cloth roll is placed on the multiple pairs of fixed roll columns 4 in sequence from bottom to top;

[0047] S3, such as Fig. 9 , pour dyeing liquid into the dyeing pool 1 until the liquid level submerges all the interlayer cloth rolls, and the control center extracts the gas in the cloth spacer air cushion 32 to the air storage chamber 301 for storage through the intelligent gas charging and discharging component 302, so that the bulged cloth spacer air cushion 32 is deflated, and at this time, the multiple layers of cloth in the interlayer cloth roll are relaxed, and there are gaps between each layer of cloth;

[0048] S4, then control the dye acceleration bars 5 on both sides of the carrier roll 3 to rotate around the fixed roll column 4, and start the micro water pump at the same time, so that the dyeing liquid enters the dye acceleration bar 5 and is sprayed toward the end surface of the interlayer cloth roll through multiple nozzles 53, and the sprayed dyeing liquid quickly enters the inner part of the interlayer cloth roll along the gap between each layer of cloth, thereby accelerating the penetration of the dyeing liquid into the cloth;

[0049] S5. The intelligent inflation and deflation component 302 is continuously controlled to make the air spacer air cushion 32 repeat the inflation and deflation process, so that each layer of fabric is continuously squeezed back and forth to achieve a full dyeing effect.

[0050] In summary, through the arrangement of multiple loading rolls 3, it is possible to put the cloth in a rolled form into the dyeing tank 1 for immersion dyeing, wherein there is an interlayer between each layer of cloth on the loading roll 3, and the multi-layer cloth can be relaxed by adjusting the interlayer, and there is a gap between the two layers, so that the dyeing liquid can smoothly dye the inner layer of the cloth. Compared with the continuous dyeing of a single piece in the prior art, the dripping loss of the dyeing liquid can be effectively reduced while ensuring the dyeing efficiency; in addition, with the arrangement of the dye acceleration strip 5, the dyeing liquid can also be assisted to be sprayed toward the inside of the interlayer cloth roll, thereby accelerating the penetration of the dyeing liquid in the inner layer of the cloth, and at the same time, with the arrangement of the water pressure detection component, the spraying intensity of the dyeing liquid toward the cloth can also be monitored, thereby achieving targeted regulation, so that the dyeing effect of the rolled cloth is better and the efficiency is higher.

[0051] The second implementation method:

[0052] Based on the first embodiment, this embodiment adds a water pressure detection component, and the rest of the parts are consistent with the first embodiment.

[0053] Fig.10 and Fig.11As shown, a water pressure detection component is installed at one end of the radial hollow strip 52 facing the sandwich cloth roll, and the water pressure detection component includes two hidden pressure strips 61 respectively located on both sides of the multiple nozzles 53 and a sensing capsule 62 fixedly connected between the two hidden pressure strips 61. The hidden pressure strip 61 is a hollow structure, and a plurality of pressure sensors 63 corresponding to the plurality of sensing capsules 62 are installed inside the hidden pressure strip 61. A plurality of contact pieces 601 corresponding to the pressure sensors 63 are also cut on the hidden pressure strip 61. The force sensing end of the pressure sensor 63 faces the contact piece 601, and the contact piece 601 is an elastic sealing structure, as shown in FIG. Fig.12 The sensing capsule 62 is a hollow elastic airbag structure that bulges outward. During the dyeing process, when the dye acceleration strip 5 is controlled to rotate, the pressure sensor 63 is arranged in the hidden pressure strip 61, which can reduce a certain error and prevent the water pressure from causing a large impact on it. During detection, the two radial hollow strips 52 can be controlled to be in the same direction, and then the multiple nozzles 53 are controlled to spray the dyeing liquid toward the end surface of the sandwich cloth roll. After the dyeing liquid enters the cloth interlayer, it continues to move toward the dye acceleration strip 5 on the other side. At this time, the sensing capsule 62 on the surface of the dye acceleration strip 5 receives the impact force directly opposite to it, driving the deformation amplitude of the sensing capsule 62 to increase, and then squeezing the contact piece 601, thereby triggering the pressure sensor 63 to change its pressure data. The greater the injection speed of the dyeing liquid, the greater the pressure change amplitude generated by the pressure sensor 63 on the opposite side, and vice versa. Based on this, the control center can adjust the pumping speed of the micro water pump to the dyeing liquid, thereby making the injected dyeing liquid more penetrable in the sandwich cloth roll, and the dyeing speed and effect are stronger.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
