Description

Technical Field

[0001] The utility model relates to the technical field of textile printing and dyeing, in particular to a satellite type pressing device and dyeing equipment. Background Art

[0002] As we all know, the reactive dye dyeing process must be carried out under alkaline conditions. Reactive dyes and alkali agents can only help the reactive dyes to be dyed when they are on the cloth. In the traditional reactive dye continuous pad dyeing process, the reactive dyes and the fixing alkali agent are mostly input into the padding machine's trough at the same time. The trough is generally large, and the reactive dyes are easily hydrolyzed when encountering water in the trough, and the degree of hydrolysis is more intense under alkaline conditions.

[0003] Alternatively, in order to prevent the reactive dye from hydrolyzing under alkaline conditions, some people apply the reactive dye and the alkali agent separately in two padders. After the reactive dye is applied in the first padder, it is dried first, and then the alkali agent is applied in the second padder. This method has large equipment and a long process, which is not conducive to energy conservation and environmental protection. In addition, the reactive dye will dissolve / fall into the alkali agent tank when entering the alkali agent tank, resulting in hydrolysis.

[0004] Since there is a limit to the amount of liquid that the fabric can carry after being dipped into the solution, under normal circumstances, the maximum liquid amount of cotton fabric is about 120%. Excessive liquid amount will cause the dye solution to flow, affecting product quality. At the same time, the higher the liquid amount under alkaline conditions, the more intense the hydrolysis of the reactive dye.

[0005] In order to achieve continuous and separate application of reactive dyes and fixing alkali in the same padder, it is first necessary to ensure that the amount of dye liquor applied for the first time is low enough to enable the fixing alkali to be applied to the fabric.

[0006] The hydrolysis of reactive dyes before they are applied to fabrics is one of the important reasons for the low dye uptake of reactive dyes. The hydrolyzed reactive dyes cannot combine with the fabrics and eventually become floating colors. The fabrics must be washed with a large amount of water after dyeing to achieve better color fastness.

[0007] In the existing technology, some technologies can obtain a uniform amount of liquid by continuous rolling for multiple times, but they cannot actually reduce the amount of liquid in the first rolling, so it is impossible to achieve "continuous and separate application of reactive dyes and fixing alkali agents".

[0008] The previously applied patent CN210177131U, a low-carrying padder, can reduce the amount of liquid carried. However, since two or more rollers are pressed together using pressure from the roller shaft ends, the pressure from the shaft ends during the pressing process can cause the working surface to bend in the direction opposite to the pressure, which can easily result in uneven thickness or liquid carried on the product. To achieve a relatively uniform liquid carry, the roller pressure cannot be too high. In addition, the roller's bearing capacity is limited, which can easily lead to uneven liquid carry. Furthermore, the limited number of rollers makes it difficult to achieve the same liquid carry on dry and wet fabrics. The final liquid carry on the fabric is still relatively high, which not only increases energy consumption during subsequent drying but also limits its scope of application. Furthermore, the reactive dye and alkali agent must still be processed in two padders, which requires more equipment, a longer process, difficult to control tension, and requires a large floor space.

[0009] Dyeing with reactive dyes has always been plagued by problems such as excessive floating color, high water and energy consumption, bulky equipment, and long processes. Industry experts have been working to address these issues, but so far there has been no ideal technical solution. Utility Model Content

[0040] In the width direction of the second core shaft, the tubular air bag or liquid bag is arranged in sections or as a whole;

[0041] When the tubular airbag or liquid bag is arranged in sections, the tubular airbag or liquid bag is divided into at least three sections: left, middle, and right. The left and right sections of the tubular airbag or liquid bag are connected through the interior of the second core shaft, and the air inlet end or the liquid inlet end is arranged at the left end or the right end of the second core shaft.

[0048] One embodiment of the present invention further provides a dyeing apparatus comprising a first fabric delivery device, a satellite-type pressing device as described in any one of the above-mentioned embodiments, a water detergent applying device, a first fabric collecting device, a second fabric delivery device, a water washing device, a drying and fixing device, a second fabric collecting device, and a guide roller assembly; the second roller of the satellite-type pressing device comprises at least one dry-wet mixing roller, a dye liquor roller, and a leveling roller, and the plurality of rollers are sequentially arranged in a satellite shape around the first roller of the satellite-type pressing device;

[0049] The guide roller assembly is provided at the input and output ends of the satellite pressing device and is used to guide the cloth to flow inside the dyeing equipment;

[0050] Furthermore, the dyeing equipment also includes a second washing device and a second drying device. The second washing device and the second drying device are located between the drying, color fixing and setting device and the second cloth collecting device, and are arranged in sequence front to back.

[0051] The satellite-type pressing device and dyeing equipment of the utility model can achieve the following technical effects:

[0052] 1. At least two of the second rollers are respectively pressed against the outer cylindrical surface of the first roller through the corresponding first pressure device, thereby reducing the amount of liquid carried by the fabric after being pressed by the satellite pressing device, so that the fabric has a uniform amount of liquid, better permeability, and reduced hydrolysis of the reactive dye; by using one or both of the material trough or the liquid storage area to separately transport the dye liquor and the auxiliary agent, the reactive dye and the color-fixing alkali agent can be separately applied through a satellite pressing device; and by providing an unfolding device at the input end of the satellite pressing device and a guide wheel and a tension detection device at the output end, the fabric is ensured to remain flat during the input and output process to avoid wrinkles.

[0053] 2. The fabric enters the nip between the first roller and each of the (1+X)th second rollers, and then between the first roller and the Nth second roller twice. The first time the fabric enters, it carries no dye. The second time, under the pressing action of each of the second rollers between the (1+X)th second rollers and the Nth second roller, the dye collected between the first roller and the first second roller is redistributed to the two layers of fabric. This significantly reduces the dye carryover rate of the fabric at the final output. Furthermore, after multiple pressing cycles, the dye carryover rate of the fabric at the output is more uniform, and the dye permeability within the fabric is also improved.

[0054] 3. By setting up multiple groups of the second rolling devices, multiple rolling is achieved between the first roller and the second roller, which improves permeability and uniformity. In addition, this embodiment significantly reduces the amount of liquid through dry-wet mixed rolling, creating conditions for the subsequent continuous application of color-fixing alkali agent. Moreover, since two groups of the material troughs or liquid storage areas are provided in the same equipment, the reactive dye and the color-fixing alkali agent can be continuously applied in the same rolling device. The alkali agent and the reactive dye will not contact before being applied to the fabric, which reduces the hydrolysis of the reactive dye and reduces the color difference before and after. At the same time, it can effectively improve the dye uptake rate, thereby reducing the washing load after reactive dye dyeing, which is beneficial to energy saving and environmental protection.

[0055] 4. Use a conveyor belt as a cloth storage device. The cloth is stacked on the conveyor belt in a natural state. The cloth is subjected to less tension, which is more suitable for knitted fabric products with greater elasticity. Alternatively, use a lifting wheel type cloth storage device. The cloth is always in a constant tension state on the cloth storage device, which is more suitable for woven fabric products with less elasticity.

[0056] 5. Through the setting of the exhaust roller, the cloth can be separated from the first roller after being pressed by the first roller and the previous second roller, pass through the exhaust roller at the corresponding position, and then enter between the first roller and the next second roller, instead of sticking to the surface of the first roller. When being pressed again, the squeezed bubbles can be discharged from the gap between the cloth and the roller surface of the first roller.

[0057] 6. By setting the second roller as an integrated second roller body and second core shaft, unlike the traditional roller with a hollow structure inside the roller body, the mechanical strength of the roller is guaranteed. By setting the first pressure device on the left and right and the second pressure device on the left and right, the left, center and right sides of the second roller body are subjected to force at the same time, which not only ensures the mechanical strength and pressure of the roller, but also the pressure of the first pressure device and the pressure of the second pressure device on the left and right can be adjusted independently or simultaneously. When the pressure (liquid carrying rate) of the left, center and right sides of the product is inconsistent, the pressure (liquid carrying rate) of the left, center and right sides of the product can be made consistent by adjusting the pressure of the corresponding parts, thereby ensuring product quality and realizing simple adjustment of the left, center and right pressures, which is a significant improvement.

[0058] 7. After the liquid or air bladder is pressurized, the second roller is propped up. In conventional rollers, when the first and second rollers are pressed together, the reaction force from the first roller causes both ends of the second roller to flex in directions opposite to the pressure of the first pressure device. The liquid or air bladder ensures uniform force across the entire second roller, preventing flexural deformation. The through hole can slide axially along the power transmission bolt to position and guide the second roller and simultaneously transmit power from the second roller to the second mandrel. This prevents damage to the second roller caused by the air or liquid bladder connected to the second mandrel from rotating relative to the second roller.

[0059] 8. Annular tube bags are sleeved on the outer ends of the shafts away from the first bearing and the second bearing. When the first roller and the second roller are pressed together, the two annular tube bags are also pressed together to offset the flexible deformation of the rollers through torque compensation. The pressing state of the pressure gap between the rollers can be adjusted by adjusting the pressure of each annular tube bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] The input end of the satellite rolling device is provided with an unfolding device 60 and / or a correction and centering device, and the unfolding device 60 is any one or more of an arc plate, an arc roller, an edge stripper, an unfolding wheel or a guide wheel, and the output end of the satellite rolling device is provided with one or both of a guide wheel and a tension detection device 70.

[0092] In this embodiment, the satellite rolling device has the following technical effects:

[0093] 1. At least two of the second rollers 31 are respectively pressed against the outer cylindrical surface of the first roller 21 through the corresponding first pressure devices 33, thereby reducing the amount of liquid carried by the fabric after being pressed by the satellite pressing device, improving permeability, and ensuring that the fabric has a uniform amount of liquid carried, thereby reducing the degree of hydrolysis of the reactive dye; by using one or both of the material trough 41 and the liquid storage area 42 to separately transport the dye liquor and auxiliary agent, the reactive dye and the color-fixing alkali agent can be separately applied through a satellite pressing device; and by providing an unfolding device 60 at the input end of the satellite pressing device and a guide wheel and a tension detection device 70 at the output end, the fabric is ensured to remain flat during the input and output process to avoid wrinkles.

[0094] Example 2

[0095] like Figure 1-5 As shown in FIG8 , based on embodiment 1, as one of the preferred embodiments, it further includes a cloth input mechanism 80 and one or more first guide rollers 11, second guide rollers 12, and third guide rollers 13;

[0096] The first guide roller 11 is provided at the entrance of the cloth, and guides the cloth sequentially between the first roller 21 and the (1+X)th second roller 31 (X is an integer equal to or greater than 1);

[0097] The second guide roller 12 is provided on the side of the output end of the Nth or (NY)th second roller 31 (Y is an integer equal to or greater than 1), and guides the cloth from between the first roller 21 and the Nth or (NY)th second roller 31 to the third guide roller 13;

[0098] One or more third guide rollers 13 are used to guide the fabric into the material trough 41 or the liquid storage area 42, so that the fabric containing the dyeing liquid and / or the auxiliary agent is pressed by the first roller 21 and the first of the second rollers 31 to obtain a fixed amount of dyeing liquid and / or auxiliary agent;

[0099] The first roller 21 and the second roller 31 are configured such that as the first roller 21 rotates, a predetermined amount of dye liquid fabric is sequentially introduced between the first roller 21 and each (1+X)th second roller 31 - between the first roller 21 and the (NY)th second roller 31 - between the first roller 21 and the Nth second roller 31, and is sequentially pressed by the first roller and each second roller. The pressed fabric is then output from between the first roller 21 and the Nth second roller 31 to the next process.

[0100] In this embodiment, the satellite rolling device has the following technical effects:

[0101] 1. The fabric enters the nip between the first roller 21 and each of the (1+X)th second rollers 31, and then between the first roller 21 and the Nth second roller 31 twice. The first time the fabric enters, it carries no dye. The second time, under the pressing action of each of the second rollers 31 between the (1+X)th second rollers 31 and the Nth second roller 31, the dye collected between the first roller 21 and the first second roller 31 is redistributed to the two layers of fabric. This significantly reduces the dye carryover rate of the fabric when it is finally delivered. Furthermore, after multiple pressing cycles, the dye carryover rate of the fabric when it is delivered is more uniform, and the dye permeability within the fabric is also improved.

[0102] In one application scenario of this embodiment, the satellite-type nip device is used to apply a solution and achieve dry-wet mixed nip to further reduce the amount of liquid carried. For dry-wet mixed nip, the fabric must be fed from the 1+X second nip rollers, then enter the material tank containing the impregnation solution, and then be nipped by subsequent nip rollers in sequence. Based on different fabrics, different processes or process requirements, the fabric can be output from any nip roller after the 1+X nip rollers.

[0103] That is, when the second roller assembly 30 is set to two, there are two corresponding second rollers 31 that are sequentially pressed against the outer cylindrical surface of the first roller 21, the first guide roller 11 is set between the cloth input mechanism 80 and the second second roller 31, and the cloth without dyeing solution enters between the first roller and the second second roller 31 from the input end of the second second roller 31 through the first guide roller 11, and the second guide roller 12 is set at the output end of the second second roller 31. After being pressed, the cloth without dyeing solution is output from the output end of the second second roller 31 and is guided by the second guide roller 12 to the first roller 31. Three guide rollers 13, the third guide roller 13 is set at the input end of the storage device 40, so that the cloth without dyeing liquid is allowed to enter the storage device 40 and obtain dye; the cloth with dyeing liquid is passed from the input end of the first second roller 31 to the space between the first roller and the first second roller 31, thereby reducing the liquid content of the cloth with dyeing liquid. Then, the cloth with dyeing liquid and the cloth without dyeing liquid are mixed by dry and wet rolling on the second second roller 31. After the dry and wet mixing, the cloth with dyeing liquid is transported from the output end of the second second roller 31 to the next processing step for subsequent drying, color fixing, shaping and other treatments.

[0104] Example 3

[0105] like Figure 1-5 As shown in FIG8 , based on Example 1, as one of the preferred embodiments, the satellite rolling device includes N second roller assemblies 30 (N is an integer equal to or greater than 3), a material trough 41 is provided below the first second roller 31 and the first roller 21, one or more impregnation wheels 401 are provided in the material trough 41, and / or the liquid storage area 42 is provided above the first second roller 31 and the first roller 21, and the liquid storage area 42 is a first liquid storage area 421;

[0106] The machine further includes a fabric feeding mechanism 80 and one or more first guide rollers 11, second guide rollers 12, and third guide rollers 13. The first guide roller 11 is positioned at the fabric inlet and guides the fabric sequentially between the first roller 21 and the (1+X)th second roller 31 (X is an integer equal to or greater than 1). The second guide roller 12 is positioned beside the output end of the (1+X)th second roller 31 and guides the fabric from between the first roller 21 and the (1+X)th second roller 31 to the third guide roller 13. The one or more third guide rollers 13 are used to guide the fabric into the material trough 41 or the first liquid storage area 421. After being impregnated with dye liquor, the fabric enters the space between the first roller 21 and the first second roller 31 to be squeezed, and a predetermined amount of dye liquor is obtained from the squeezed fabric.

[0107] As the first roller 21 rotates, the cloth enters the space between the first roller 21 and each (1+X)th second roller 31, then enters the space between the first roller 21 and each (NY)th second roller 31 (Y is an integer greater than or equal to 0), and then enters the space between the first roller 21 and the Nth second roller 31. The cloth is then output from the space between the first roller 21 and the Nth second roller 31 to the next process for subsequent drying, color fixing, shaping, and other treatments.

[0108] A closed loop structure is formed between the first guide roller 11 or the second guide roller 12 and the third guide roller 13, the first roller 21 and the second roller 31, and the first guide roller 11 and the cloth feeding mechanism 80 are arranged in the closed loop structure;

[0109] In which, the end sealing assembly 402 and the feed pipe 403 are provided at both ends between at least the first roller 21 and the (NY)th second roller 31, and the feed pipe 403 is provided above the first roller 21 and the (NY)th second roller 31. A second liquid storage area 422 is formed above the first roller 21 and the (NY)th second roller 31, and the dye solution or auxiliary agent is transported to the second liquid storage area 422 through the feed pipe 403.

[0110] In this embodiment, the satellite rolling device has the following technical effects:

[0111] 1. Between the first roller 21 and the first of the second rollers 31, the cloth is pressed to obtain a fixed amount of reactive dye solution. Then, after passing through the first roller 21 and each (1+X)th second roller 31, the cloth undergoes multiple dry-wet mixing and rolling processes to obtain a low liquid carrying rate, preferably 50-60%. At this point, the liquid carrying rate of the cloth has not reached saturation and can still carry more solution.

[0112] The cloth then sequentially enters between the first roller 21 and each (NY)th second roller 31 to obtain a solution of a color-fixing alkali agent. Preferably, the cloth has a liquid carrying rate of 100-120% at this time (the saturated liquid carrying rate of pure cotton cloth is approximately 120%). Although a portion of the reactive dye solution carried by the cloth will fall off and dissolve into the liquid storage area 42, the storage capacity of the liquid storage area 42 is limited, and the cloth's flow rate in the liquid storage area 42 is very short, approximately 1%-5% of that of a traditional padder. During high-speed operation, the solution exchange rate is relatively fast, and the solution exchange equilibrium can be quickly reached. Therefore, the amount of reactive dye shedding and hydrolysis in the liquid storage area 42 is limited, and will not have a significant impact on product quality.

[0113] The fabric then enters the space between the first roller 21 and the Nth second roller 31, where it is pressed again. This further pressing process results in a more evenly distributed liquid content and improved permeability. Finally, the fabric is discharged from the space between the first roller 21 and the Nth second roller 31 to the next process for subsequent drying, color fixing, and shaping.

[0114] 2. By setting up multiple groups of the second rolling devices, multiple rolling is achieved between the first roller 21 and the second roller 31, which improves permeability and uniformity. In addition, this embodiment significantly reduces the amount of liquid through dry and wet mixed rolling, creating conditions for the subsequent continuous application of the color-fixing alkali agent. Moreover, since two groups of the material troughs 41 or liquid storage areas 42 are provided in the same equipment, the reactive dye and the color-fixing alkali agent can be continuously applied in the same rolling device. The alkali agent and the reactive dye will not contact before being applied to the fabric, which reduces the hydrolysis of the reactive dye and reduces the color difference before and after. At the same time, it can effectively improve the dye uptake rate, thereby reducing the washing load after reactive dyeing, which is beneficial to energy saving and environmental protection.

[0115] In one application scenario of this embodiment, the satellite-type rolling device is used to apply two solutions (such as dyes and auxiliaries, respectively) and achieve dry-wet mixed rolling. When the second roller assembly 30 is set to three, there are corresponding three second rollers 31 that are sequentially pressed against the outer cylindrical surface of the first roller 21. The first guide roller 11 is arranged between the cloth input mechanism 80 and the second second roller 31, the second guide roller 12 is arranged at the output end of the third second roller 31, and the third guide roller 13 is arranged at the input end of the storage device 40; a second liquid storage area 422 is provided between the first roller 21 and the third second roller 31;

[0116] The fabric not applied with dye passes through the first guide roller 11 from the input end of the second second roller 31 and enters between the first roller and the second second roller 31 and the third second roller 31. The second guide roller 12 is set at the output end of the third second roller 31. The fabric not applied with dye after pressing is output from the output end of the third second roller 31 and guided by the second guide roller 12 to the third guide roller 13, so that the fabric not applied with dye enters the storage device 40 and obtains dye; the fabric obtained with dye enters the first roller 21 and the third roller 31 from the input end of the first second roller 31. The cloth that has received the dye is passed between the first and second rollers 31 to reduce the liquid content of the cloth that has received the dye, and then the cloth that has received the dye and the cloth that has not been dyed are mixed by dry and wet rolling on the second second roller 31. After the dry and wet mixing, the cloth that has received the dye is transported from the output end of the second second roller 31 to the second liquid storage area 422 and obtains the auxiliary agent. The cloth that has received the auxiliary agent enters between the third second roller 31 and the first roller 21 to reduce the liquid content of the cloth that has received the auxiliary agent, and then is output from the output end of the third second roller 31 to the next processing step for subsequent drying, color fixing, shaping and other treatments.

[0117] Example 4

[0118] like Figure 4 and 5 As shown, based on any one of Examples 1-3, in one of the preferred embodiments, a cloth storage device 90 is further provided, the cloth storage device 90 is a conveyor belt device, the conveyor belt device at least includes a conveyor belt (907), a conveyor belt support wheel (908) and a conveyor belt (907) power mechanism, the cloth storage device 90 is provided between the cloth after it is led out from between the first roller 21 and the Nth or (NY)th second roller 31 to the material trough 41 or the liquid storage area 42;

[0119] The cloth storage device 90 is used to allow the cloth to be drawn out from between the first roller 21 and the Nth or (NY)th second roller 31 and then fall from top to bottom onto the conveyor belt (907), and be transported forward along with the conveyor belt (907). The linear speed of the conveyor belt (907) is not greater than the speed of the main machine, so that the cloth can be stacked on the conveyor belt (907) after being stretched.

[0120] In this embodiment, the satellite rolling device has the following technical effects:

[0121] 1. A large amount of fabric can be stored, and long-term continuous production can be achieved. Moreover, since the conveyor belt (907) is used as the fabric storage device 90, the fabric is naturally stacked on the conveyor belt (907), and the fabric is subjected to less tension, which is more suitable for knitted fabric products with greater elasticity.

[0122] In one of the application scenarios of this embodiment, the dyed fabric after dry-wet mixing is output from the output end of the Nth second roller 31, and the fabric that has only undergone dry-wet mixing but has not been dyed is output from the output end of the Nth or second (NY) second roller 31. The dyed fabric is sandwiched between the outer cylindrical surface of the first roller 21 and the undyed fabric during dry-wet mixing.

[0123] Example 5

[0124] like Figure 4 and 5 As shown, on the basis of any one of Examples 1-3, as one of the preferred embodiments, a cloth storage device 90 is further provided, and the cloth storage device 90 is a lifting wheel group type cloth storage device, and the lifting wheel group type cloth storage device at least includes a frame, a fixed wheel group 91, a lifting wheel group 92 and a counterweight device 93; the fixed wheel group 91 includes a plurality of fixed wheels 901, each of the fixed wheels 901 is rotatably connected to a fixed beam 902, and the fixed beam 902 is fixedly connected to the frame; the lifting wheel group 92 includes a plurality of lifting wheels 903 Each of the lifting wheels 903 is rotatably connected to a lifting beam 904, and the lifting beam 904 is slidably connected to the frame via a sliding device, and the sliding device is provided with a sliding wheel 905; each of the fixed wheels 901 and each of the sliding wheels 905 is staggered in sequence front and back, and the fixed beam 902 and the fixed wheels 901 are arranged above the cloth storage device 90; the cloth storage device 90 is arranged in front of the material trough 41 after the cloth is led out from between the first roller 21 and the Nth or (NY)th second roller 31;

[0125] The cloth is led out from between the first roller 21 and the Nth or (NY)th second roller 31 and enters the cloth storage device 90 , and the cloth sequentially crosses through each of the fixed wheels 901 and each of the sliding wheels 905 ;

[0126] The counterweight device 93 is configured to pull the lifting wheel 903 and the lifting beam 904 to a position above the cloth storage device 90, so that under the tension of the cloth, the lifting wheel 903 and the lifting beam 904 move downward following the sliding device, so that the cloth obtains a constant tension; the counterweight device 93 is a counterweight block or a pneumatic cylinder or a hydraulic cylinder, and the tension of the cloth is changed by adjusting the counterweight block or adjusting the pressure of the pneumatic cylinder or the hydraulic cylinder.

[0127] In this embodiment, the satellite rolling device has the following technical effects:

[0128] 1. In order to store more cloth, more fixed wheels 901 and sliding wheels 905 can be provided, or more rows of fixed wheels 901 and sliding wheels 905 can be provided, and / or the up and down sliding stroke can be lengthened; and a lifting wheel group type cloth storage device is adopted. The cloth on the cloth storage device 90 is always in a state of constant tension, which is more suitable for woven cloth products with less elasticity.

[0129] Example 6

[0130] In the prior art, the fabric carrying the dye liquid is pressed against the outer circle of the first roller 21 and is moved along the outer circle of the first roller 21. Air sometimes exists between the fabric and the outer circle of the first roller 21. For densely woven fabrics, this air is not easy to be discharged, and bubbles are formed at the pressing point of the first roller 21 and the second roller 31. The presence of these bubbles will cause the dye liquid on the surface of the fabric to be unevenly distributed, forming strip marks on the surface of the fabric, which affects the fabric effect.

[0131] Therefore, if Figure 1-5 As shown in FIG8 , on the basis of any one of Examples 1-5, in one of the preferred embodiments, an exhaust roller 14 is provided between two adjacent second rollers 31, and both ends of the exhaust roller 14 are rotatably provided on the frame 10. The exhaust roller 14 is provided close to the outer circle of the first roller 21, so that the cloth is separated from the first roller 21 after being pressed by the first roller 21 and the previous second roller 31, and passes through the exhaust roller 14 at the corresponding position, so as to generate a gap between the cloth and the first roller 21.

[0132] In this embodiment, the satellite rolling device has the following technical effects:

[0133] 1. The arrangement of the degassing roller 14 allows the fabric to pass through the first roller 21 and the preceding second roller 31, then escape from the first roller 21, pass through the corresponding degassing roller 14, and then reenter between the first roller 21 and the next second roller 31, rather than remaining adhered to the surface of the first roller 21. During the next degassing, expelled bubbles can be expelled from the gap between the fabric and the surface of the first roller 21. This repeated process, repeated after the fabric is discharged, prevents the formation of bubbles at the intersection of the first roller 21 and the second roller 31, ensuring that the fabric surface is not affected by bubbles.

[0134] Example 7

[0135] In traditional technologies, either the mechanical strength of the rollers is insufficient, or they cannot be adjusted independently on the left, center, and right sides, or they have defects such as complex structure and bulky machinery. In addition, in order to achieve uniform rolling, additional pressure needs to be applied to offset the flexible deformation of the rollers, so a considerable amount of pressure will be lost.

[0136] Therefore, if Figure 1-5 As shown in FIG8 , based on the above embodiments, in one of the preferred embodiments, the second roller assembly 30 at least includes a second roller 31, a second bearing 32, a third bearing 35, a first pressure device 33, a second pressure device 36, a first sliding device 34, and a second sliding device 37;

[0137] The second roller 31 includes a second roller body 301 and a second mandrel 302 located inside the second roller body 301. The second mandrel 302 is sleeved inside the second roller body 301. The middle portion of the second mandrel 302 is connected to or integrally formed with the inner circle of the second roller body 301. The outer diameters of both ends of the second mandrel 302 are smaller than the inner diameter of the second roller body 301.

[0138] Both ends of the second roller body 301 are equipped with left and right second bearings 32 and left and right second bearing seats 38 for supporting the second roller body 301. The second bearing seats 38 are connected to the first sliding device 34 and the first pressure device 33.

[0139] The pressure of the first pressure device 33 is applied to both ends of the second roller body 301 through the left and right second bearings 32 toward the first roller 21;

[0140] At the same time, left and right third bearings 35 and left and right third bearing seats 39 are provided at both ends of the second core shaft 302 to support the second core shaft 302. The third bearing seats 39 are connected to the second sliding device 37 and the second pressure device 36. The pressure of the second pressure device 36 is applied to the middle part of the second roller body 301 through the second core shaft 302 in the direction of the first roller 21. The first sliding device 34 and / or the second sliding device 37 can be a slide rail, a slider device or a corresponding bearing seat limit fixing member.

[0141] The first pressure device 33 and the second pressure device 36 respectively drive the second roller body 301 and the second core shaft 302 to slide along the first sliding device 34 and the second sliding device 37, so that the second roller 31 is driven by the first pressure device 33 and the second pressure device 36 to be pressed together with the first roller 21 in a detachable manner.

[0142] In this embodiment, the satellite rolling device has the following technical effects:

[0143] 1. Because the second roller 301 and the second mandrel 302 are connected or integrally arranged, the second roller 31 has sufficient mechanical strength. The pressure of the left and right first pressure devices 33 acts on both ends of the second roller 301, and the pressure of the left and right second pressure devices 36 acts on the middle part of the second roller 301 through the middle part of the second mandrel 302. That is, the pressure of the left and right first pressure devices 33 and the pressure of the left and right second pressure devices 36 both act on the second roller 301 in the same direction. The second roller 301 is subjected to the combined force of the first pressure device 33 and the left and right second pressure devices 36, without pressure loss. This allows the second roller 301 to obtain a higher pressure and thus a lower liquid pick-up rate.

[0144] At the same time, since the pressure of the first pressure device 33 on the left and the pressure of the second pressure device 36 on the left and can be adjusted independently or simultaneously, when the pressure (liquid carrying rate) on the left, middle and right sides of the product is inconsistent, the pressure (liquid carrying rate) on the left, middle and right sides of the product can be adjusted by adjusting the pressure of the corresponding parts to achieve consistency in the pressure (liquid carrying rate) on the left, middle and right sides of the product, thereby ensuring product quality.

[0145] 2. By configuring the second roller 31 as an integral second roller body 301 and a second core shaft 302, unlike the traditional roller with a hollow structure inside the roller body, the mechanical strength of the roller is ensured, and by configuring the left and right first pressure devices 33 and the left and right second pressure devices 36, the left, center and right sides of the second roller body 301 are subjected to force at the same time, which not only ensures the mechanical strength and pressure of the roller, but also the pressure of the first pressure device 33 and the pressure of the left and right second pressure devices 36 can be adjusted independently or simultaneously. When the pressure (liquid carrying rate) of the left, center and right sides of the product is inconsistent, the pressure (liquid carrying rate) of the left, center and right sides of the product can be made consistent by adjusting the pressure of the corresponding parts, thereby ensuring product quality and realizing simple adjustment of the left, center and right pressures, which is a significant improvement.

[0146] Example 8

[0147] like Figure 6 、 7As shown, based on the above embodiments, in one of the preferred embodiments, the second roller 31 is an air bag or liquid bag roller, the second roller 31 includes a second roller body 301 and a second mandrel 302 located inside the second roller body 301, the first pressure device 33 is connected to both ends of the second mandrel 302, the second mandrel 302 is sleeved inside the second roller body 301, the outer diameter of the second mandrel 302 is smaller than the inner diameter of the second roller body 301, a tubular air bag or tubular liquid bag is provided between the outer circle of the second mandrel 302 and the inner circle of the second roller body 301, the outer circle of the second mandrel 302 is provided with a spiral groove that cooperates with the tubular air bag or tubular liquid bag, and part of the circumference of the tubular air bag or tubular liquid bag is provided in the spiral groove as it is spirally wound;

[0148] The air bag or liquid bag is a high-pressure resistant oil pipe or high-pressure air pipe; a tube bag hole is provided at the center of the second core shaft 302, and the air inlet end or liquid inlet end of the air bag or liquid bag is connected to the inner end of the tube bag hole, or the air inlet end or liquid inlet end of the air bag or liquid bag leads to the end of the second core shaft 302 through the tube bag hole; the end of the second core shaft 302 is rotatably connected to a high-pressure resistant rotary joint 305, and the air inlet end or liquid inlet end of the air bag or liquid bag is connected to an external pressure regulating device through the rotary joint 305;

[0149] The airbag or liquid bag is pressurized to prop up the second roller 301, and the pressure of the first pressure device 33 is evenly transmitted to the second roller 301 through the second core shaft 302-the airbag or liquid bag, and then evenly transmitted to the first roller 21;

[0150] In the width direction of the second core shaft 302, the tubular airbag or liquid bag is arranged in sections or as a whole.

[0151] In the overall setting state, the pressure of the tubular airbag or liquid bag can only generate overall pressure on the second roller body 301. The magnitude of the overall pressure is adjustable, but the pressure at both ends and the middle part of the second roller body 301 cannot be adjusted independently.

[0152] Therefore, in one application scenario of this embodiment, when the tubular airbag or liquid bag is arranged in sections, the tubular airbag or liquid bag is divided into at least three sections: left, middle, and right. The left and right sections of the tubular airbag or liquid bag are connected through the interior of the second core shaft 302, and the air inlet end or the liquid inlet end is arranged at the left end or the right end of the second core shaft 302. The left and right sections of the tubular airbag or liquid bag share the same pressure regulating device or can be adjusted independently; the air inlet end or the liquid inlet end of the tubular airbag or liquid bag located in the middle is arranged at the right end or the left end of the second core shaft 302, and uses a separate pressure regulating device.

[0153] One or more threaded holes are radially provided at both ends of the second core shaft 302, and one or more through holes are radially provided at both ends of the second roller body 301. The power transmission bolts are fitted in the threaded holes and the through holes. The diameter of the through holes is larger than the diameter of the power transmission bolts. The second roller body can slide in the axial direction of the power transmission bolts.

[0154] In this embodiment, the satellite rolling device has the following technical effects:

[0155] 1. After the liquid or air bladder is pressurized, the second roller 301 is propped up. When the first roller 21 and the second roller 31 are pressed together, the reaction force from the first roller 21 causes the ends of the second roller 301 to flex in opposite directions toward the pressure of the first pressure device 33. The liquid or air bladder ensures uniform force across the entire second roller, preventing flexural deformation. The through hole slides axially along the power transmission bolt, positioning and guiding the second roller 301 while simultaneously transmitting power from the second roller 301 to the second mandrel 302. This prevents the air bladder or liquid bladder connected to the second mandrel from rotating relative to the second roller, potentially causing damage.

[0156] 2. Under the pressurized state, the pressure of the tubular airbags or liquid bags at both ends is the same and the pressure can be adjusted. The pressure of the tubular airbags or liquid bags in the middle can be the same as or different from that at the two ends. After the airbags or liquid bags are pressurized, they prop up the second roller body 301. The pressure of the first pressure device 33 is evenly transmitted to the second roller body 301 through the second core shaft 302-the airbags or liquid bags, and then to the first roller 21. By adjusting the pressure difference between the airbags or liquid bags at both ends and the middle part, the height of the second roller body 301 can be adjusted to offset the flexural deformation of the second roller 31 caused by the pressing of the first roller 21 and the second roller 31.

[0157] Example 9

[0158] like Figure 6 、 7 As shown, in a conventional rolling device, when the first roller 21 and the second roller 31 are pressed together, there is a substrate between the first roller 21 and the second roller 31, and the second roller 31 is subjected to force at both ends, and the middle part thereof will inevitably produce flexible deformation or deformation tendency away from the first roller 21.

[0159] Therefore, on the basis of the above embodiments, in one of the preferred embodiments, both ends of the first roller 21 and at least one of the second rollers 31 are provided with an annular tubular bag 303, and the annular tubular bag 303 is an air bag or a liquid bag. An annular tubular bag support seat 304 is sleeved on the outer end of the shaft end away from the first bearing 22 and the second bearing 32. The outer circle of the annular tubular bag support seat 304 is provided with an annular groove 18, and the air bag or liquid bag sleeve portion is provided in the annular groove 18. The outer circle of the annular tubular bag support seat 304 is matched with the inner circle of the air bag or the liquid bag. The outer diameter size of each annular tubular bag 303 is matched with the outer diameter of the corresponding first roller 21 and the second roller 31. When the first roller 21 and the second roller 31 are pressed together, the two annular tubular bags 303 are also pressed together.

[0160] The first roller 21 and the second roller 31 are connected to the center of the roller 21 and the second roller 31 with a high-pressure resistant rotary joint 305. The air inlet or liquid inlet of the air bag or liquid bag is connected to the corresponding rotary joint 305 through a tube hole 306, and then connected to an external pressure regulating device. The pressure of each air bag or liquid bag can be adjusted independently or as a whole.

[0161] Among them, the second roller 31 is a uniform roller, which is configured to adjust the bending degree of the roller through the pressure of the built-in hydraulic system to offset the flexural deformation of the roller; or, the second roller 31 is an intermediate support roller, which is configured to resist the flexural deformation of the middle part of the roller by supporting the middle part of the roller; or, the second roller 31 is a magnetic adsorption roller, which is configured to resist the flexural deformation of the middle part of the roller by generating adsorption force or pressure through a magnetic field set in the roller.

[0162] In this embodiment, the satellite rolling device has the following technical effects:

[0163] 1. An annular tube bag 303 is sleeved on the outer end of the shaft away from the first bearing 22 and the second bearing 32. When the first roller 21 and the second roller 31 are pressed together, the two annular tube bags 303 are also pressed together, offsetting the flexible deformation of the rollers through torque compensation. The pressing state of the pressure gap between the rollers can be adjusted by adjusting the pressure of each annular tube bag 303.

[0164] In one of the application scenarios of this embodiment, the second rolling roller 31 can also be any one of the following rolling rollers: the rolling roller disclosed in 201720519880.2, the adjustable middle and high pressure roller assembly and rolling device disclosed in 202320117251.2, the rolling device that makes the roller body uniformly stressed disclosed in 202320133925.8, the suspended pressure roller and rolling device disclosed in 202320116952.4, the pressure roller assembly and rolling device with adjustable deflection disclosed in 202320117245.7, and the rolling device provided with a torque balance adjustment device disclosed in 202320116897.9.

[0165] Example 10

[0166] like Figure 9 、 10 As shown, one embodiment of the present invention provides a dyeing device, which includes two or more groups of satellite pressing devices described in any one of the above-mentioned embodiments, and the two or more groups of satellite pressing devices are arranged in sequence front and back, or a heating device is connected to the rear of each group of satellite pressing devices to heat, dry or shape the fabric output by the previous group of satellite pressing devices.

[0167] In this embodiment, the satellite rolling device has the following technical effects:

[0168] 1. The satellite-type pressing device of the first group of the present invention applies the reactive dye solution to the fabric, obtaining a low liquid carrying rate, preferably a liquid carrying rate of 50-60%. The liquid carrying rate of the fabric is not saturated, so after entering the satellite-type pressing device of the second group of the present invention, the fabric can still carry more solution, preferably a liquid carrying rate of 100-120% (the saturated liquid carrying rate of pure cotton fabric is about 120%). The solution in the satellite-type pressing device of the second group is a color fixing alkali agent, preferably an alkali agent is arranged above the two rollers of the satellite-type pressing device of the second group. The upper part between the two rollers of the satellite-type pressing device of the second group is provided with a fixing agent. A liquid storage area 42 is formed, and the cloth runs downward from the upper part between the two rollers of the second group of satellite pressing devices. Although a part of the active dye solution applied to the cloth by the satellite pressing device of the previous group of the present invention will fall off and dissolve into the liquid storage area 42, the storage capacity of the liquid storage area 42 is limited, and the flow of the cloth in the liquid storage area 42 is very short, about one tenth of that of a traditional roller. During high-speed operation, the solution exchange rate is relatively fast, and the solution exchange equilibrium can be reached quickly. Therefore, the amount of active dye shedding and hydrolysis in the liquid storage area 42 is limited, which will not have a significant impact on product quality.

Multiple springs are annularly distributed between the circular sealing plate and the spring support. The circular sealing plate, the spring, and the spring support all rotate with the first roller or the second roller 301.

[0173] Under the elastic force of the spring, the circular sealing plate slidably contacts the end surface of the elastic layer 17. By adjusting the elastic force of the spring, the degree of sealing between the circular sealing plate and the end surface of the elastic layer 17 can be adjusted.

Preferably, the axial pressure assembly and / or radial pressure assembly is a spring plunger.

[0178] In this application scenario, by setting the axial pressure component and the radial pressure component, it can be ensured that the end of the second roller 31 or the first roller 21 is tightly sealed, which is conducive to continuous production.

[0179] In one of the application scenarios of this embodiment, a material trough 41 is provided below the first roller 21, and a reflux hole is provided on the upper part of the material trough 41.

[0181] Example 12

[0182] Based on the embodiment 1 or 11, in one example, the roller body of the first roller 21 is a mesh roller with a concave or convex dot-shaped texture pattern on the surface.

[0183] In this embodiment, since the roller body has a certain yield strength and the pressure of each pressure device cannot be increased indefinitely, in order to reduce the pressure of the second pressure device 36 and the second pressure device 36, the outer cylindrical surface of the roller body is pre-machined into a smaller middle-height shape to meet the minimum middle-height requirements, that is, the diameter of the outer cylindrical surface of the first roller body and the second roller body 301 is slightly reduced from the middle to the two ends (for example, the middle height is 0.1NN).

[0184] In one of the application scenarios of this embodiment, the second roller 31 and the plane where the axis of one of the first rollers 21 is located are inclined, the first roller 21 is arranged below the second roller 31, and the material trough 41 is arranged below the second roller 31 and the first roller 21, and multiple impregnation wheels 401 are arranged in the material trough 41 in parallel and pressed in the vertical direction, the first impregnation wheel 401 is rotatably connected to the material trough 41, and the remaining impregnation wheels 401 are detachably abutted against the first impregnation wheel 401 in sequence through the X-th slide rail, and the last impregnation wheel 401 is detachably abutted against the first roller 21, and the material trough 41 is connected to a material trough 41 lifting slide rail and a material trough 41 lifting cylinder or airbag, and the material trough 41 slides along the material trough 41 lifting slide rail through the material trough 41 lifting cylinder, driving each of the impregnation wheels 401 and the first roller 21 in the material trough 41 to be pressed or separated in sequence.

[0185] Furthermore, a trough lifting airbag is connected to the bottom of the trough 41 lifting cylinder. The stroke of the trough 41 lifting cylinder plus the stroke of the trough lifting airbag is the total stroke of the trough 41. The setting of the trough 41 lifting cylinder can make the trough 41 obtain a larger lifting stroke. Since the airbag can allow a larger deviation, it is relatively stable compared to the cylinder. The setting of the trough lifting airbag can make the pressure between the impregnation wheels 401 and between the last impregnation wheel 401 and the second roller 31 more stable.

[0186] As a further solution in the application scenario, the end shaft of the bottom impregnation wheel 401 passes through the material trough 41, the end shaft of the bottom impregnation wheel 401 is connected to a mechanical seal bearing, and is rotatably connected to the material trough 41 through the mechanical seal bearing, and one of the end shafts of the bottom impregnation wheel 401 is connected to a power device 50.

[0187] Alternatively, the topmost impregnation wheel 401 is rotatably connected to the frame 10, and at least one of its end shafts extends outside the trough 41, transmitting power to the second roller 31 via gears. The trough 41 is connected to a trough lifting device, which is connected to the frame 10 and includes a trough lifting limit device, a lifting guide device, a lifting power device 50, etc.

[0188] As a further solution in the application scenario, it also includes an impregnation wheel lifting device, which includes a slide groove, which is arranged on the inner wall of the two ends of the material trough 41, and the end shaft of the impregnation wheel 401 is slidably arranged in the slide groove. Each of the impregnation wheels 401 is pressed or disengaged in turn by an air pressure or oil pressure lifting device or a manual lever device arranged on the slide groove.

[0189] As a further solution in the application scenario, the end shaft of the impregnation wheel 401 is provided with a rolling bearing, and the rolling bearing is arranged to roll or slide in the chute.

[0190] The shaft end of the impregnation wheel 401 is rotatably connected to the impregnation wheel lifting device, which drives each impregnation wheel 401 to rise in sequence and stops when it rises to the working position. When the material trough 41 descends, the impregnation wheel lifting device drives each impregnation wheel 401 to descend in sequence.

[0191] In one application scenario of this embodiment, the end shafts of two adjacent impregnation wheels 401 are movably connected via a hook or a ring, and a certain distance is maintained between the adjacent impregnation wheels 401 via the hook or the ring.

[0192] In one of the application scenarios of this embodiment, a plurality of pins or screws are arranged at intervals above and below the chute. Except for the bottommost impregnation wheel 401, the remaining impregnation wheels 401 can be fixed on the chute by pins or screws, and maintain a preset distance between the adjacent impregnation wheels 401. When the pins or screws are separated from the chute, the impregnation wheels 401 press each other under the action of their own gravity.

[0193] In one of the application scenarios of this embodiment, in order to facilitate the cleaning of the material trough 41 and the pulling of the material, the material trough 41 is also provided with a flipping device. The material trough 41 is rotatably arranged on the inner side of the frame 10 around the axis of the lowest impregnation wheel 401, and the material trough 41 can be tilted and flipped by applying external power.

[0194] In one of the application scenarios of this embodiment, in order to facilitate the pulling of materials or the selection of whether to dip and dye, the material trough 41 is provided with a material trough lifting device. Under the action of a cylinder, a hydraulic cylinder or manual force, the material trough 41 is guided by a lever or a slide rail to generate a lifting action, and the material trough 41 is moved away from the working position.

[0195] In one of the application scenarios of this embodiment, in order to facilitate the cleaning of the material trough 41 and the replacement of materials, the material trough 41 is a movable material trough 41, and four casters are provided at the bottom of the material trough 41. During production, the impregnation wheel 401 group is lowered and immersed in the material trough 41. When changing materials, the impregnation wheel 401 group is raised and the material trough 41 is removed and replaced.

[0196] In one application scenario of this embodiment, the material tank 41 is also provided with a cooling or heating device with a double-layer sandwich structure, and the functional solution in the material tank 41 is maintained at a preset temperature by injecting steam or heat transfer oil or hot water or cold water into the sandwich.

[0197] Example 13

[0198] On the basis of Example 12, the following operation can also be implemented: the cloth enters the material trough 41, passes through the impregnating wheels 401 in turn, and the impregnating wheels 401 are pressed together in turn. The last impregnating wheel 401 is pressed together with the first roller 21. The cloth enters the first roller 21 from the last impregnating wheel 401, runs around and follows the first roller 21, enters between the first second roller 31 and the first roller 21, the cloth is pressed for the first time, then separates from the first roller 21, and passes over the first exhaust roller 14, then enters between the second second roller 31 and the first roller 21, is pressed again, and after being pressed, the cloth separates from the first roller 21, and passes over the second exhaust roller 14, then enters between the third second roller 31 and the first roller 21, is pressed for the third time, and then output to the next process for drying, color fixing, shaping and other treatments.

[0199] The material trough 41 contains a reactive dye solution. After being squeezed by the impregnation wheels 401, the cloth carries excess dye solution. After being pressed between the first second roller 31 and the first roller 21, a certain amount of reactive dye solution is obtained. At this stage, the pressure between the first second roller 31 and the first roller 21 is set to a relatively high level so that the cloth can obtain a lower liquid carryover rate, preferably a liquid carryover rate of 60%.

[0200] A color-fixing alkali agent is placed above the second roller 31 and the first roller 21. When the cloth passes between the second roller 31 and the first roller 21, it is pressed for the second time to obtain a mixed solution of a certain amount of reactive dye and color-fixing alkali agent. At this stage, the pressure between the second roller 31 and the first roller 21 is set to a relatively small value so that the cloth can obtain a higher liquid-carrying rate, preferably a liquid-carrying rate of 120%.

[0201] As the machine operates, the fabric enters the third nip between the second roller 31 and the first roller 21, where it is nipped a third time. This third nip serves to further homogenize the solution carried on the fabric surface. The pressure is preferably no greater than that of the second nip to prevent the mixed solution from being squeezed out. After the third nip, the fabric is delivered to the next process for drying, color fixing, and shaping.
