Description

Technical Field

[0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a continuous washing-dyeing device and method based on a satellite-type pressing device. Background Art

[0002] As we all know, in the traditional continuous dyeing process, the pre-treatment washing process and the dyeing process are carried out separately, and the pre-treatment washing process must be dried. Otherwise, it is difficult to apply the dye solution in the dyeing process due to the excessive amount of liquid. There are problems such as many equipments, large floor space, and high energy consumption.

[0003] 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 agents are mostly input into the material trough of the padder at the same time. The material trough is generally large, and the reactive dyes are easily hydrolyzed when they meet water in the material trough, and the degree of hydrolysis is more intense under alkaline conditions.

[0004] Alternatively, in order to prevent the active dye from being hydrolyzed under alkaline conditions, some people apply the active dye and the alkali agent separately in two rollers. After applying the active dye in the first roller, it is dried first, and then the alkali agent is applied in the second roller. This method has large equipment and a long process, which is not conducive to energy conservation and environmental protection. In addition, when the active dye enters the alkali agent tank, it will also dissolve / fall into the alkali agent tank and produce hydrolysis.

[0005] Since there is a limit to the amount of liquid that the cloth can carry after being dipped in the solution, under normal circumstances, the maximum amount of liquid that cotton fabric can carry is about 120%. Too much liquid will cause the dye to flow and affect the product quality. At the same time, the higher the liquid amount under alkaline conditions, the more intense the hydrolysis of the reactive dye will be.

[0006] In order to achieve continuous and separate application of reactive dyes and fixing alkali agents in the same padder, it is first necessary to ensure that the amount of dye liquor applied for the first time is low enough so that the fixing alkali agent can be applied to the fabric.

[0007] The hydrolysis of reactive dyes before they are applied to fabrics is one of the important reasons for the low dyeing rate 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.

[0008] In the prior art, 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".

[0009] The previously applied CN210177131U patent for a low liquid-carrying roller can reduce the liquid-carrying amount to a certain extent. However, since two or more rollers are pressed together through the pressure of the roller shaft ends, the pressure of the shaft ends during the pressing process will cause the working surface to bend and deform in the direction opposite to the pressure direction, which can easily cause the product to have uneven thickness or liquid-carrying amount on the left, middle and right. In order to obtain a more uniform liquid-carrying amount, the pressure of the roller cannot be too large. In addition, the bearing capacity of the roller is limited, which can easily lead to uneven liquid-carrying amount. In addition, the number of rollers is limited, and it is difficult to obtain the same liquid-carrying amount on dry and wet cloth. Finally, the liquid-carrying amount of the cloth is still relatively high, which not only increases the energy consumption during subsequent drying, but also limits its scope of application.

[0010] In addition, it can only reduce the amount of liquid on the cloth once, and the amount of liquid reduction is limited.

[0011] In addition, the reactive dyes and alkali agents still need to be processed in two padders, which requires many devices, a long process, difficult tension control, and a large area of ​​land.

[0012] For a long time, the dyeing of reactive dyes has had problems such as excessive floating color, large water consumption / high energy consumption / large equipment / long process, etc. Industry experts have been committed to solving these problems, but there is no ideal technical solution so far.

[0013] For disperse dyes or coatings, a higher amount of liquid not only results in higher energy consumption for subsequent drying, but also causes the dye to migrate disorderly at high temperatures, resulting in uneven dyeing or color spots, affecting product quality. In addition, the traditional pre-dyeing washing and dyeing steps are run independently, with multiple equipment, large land area, high energy consumption, and low efficiency.

[0014] Therefore, in recent years, many industry players have been working hard to explore a process and equipment that can perform continuous pre-treatment washing and dyeing and is energy-saving and environmentally friendly. Summary of the invention

[0020] In one of the schemes of the present invention, an exhaust roller is arranged between two adjacent second rollers, and both ends of the exhaust roller are rotatably arranged on the frame. The exhaust roller is arranged close to the outer circle of the first roller, so that the cloth is separated from the first roller after being pressed by the first roller and the previous second roller, and passes through the exhaust roller at the corresponding position to create a gap between the cloth and the first roller to exhaust air. After passing through the exhaust roller, the cloth enters between the first roller and the next second roller and is pressed again.

[0021] In one of the schemes of the present invention, a continuous water washing and dyeing method based on a satellite type pressing device is also pointed out, which can be used for the continuous water washing and dyeing equipment based on a satellite type pressing device described in any one of the above multiple schemes, and the method comprises: Step 1: Sending the initial fabric to between the first roller and each dry-wet mixing roller through the first fabric sending device, so that the initial fabric and the liquid-containing fabric output from the washing device are mixed in dry and wet conditions, so that the initial fabric is hydrated; wherein the liquid-containing fabric that enters initially is the lead fabric, and the liquid-containing fabric that enters subsequently is the first semi-finished fabric after washing; Step 2, guiding the initial cloth after dry-wet mixing into the washing device through the guide roller assembly, washing and rolling by the rollers corresponding to the last group of the fifth roller assembly and the sixth roller assembly, reducing the amount of liquid for the first time, and obtaining the first semi-finished cloth, wherein the amount of liquid in the first semi-finished cloth is 30-120%; Step 3, guiding the first semi-finished cloth and the initial cloth sent by the first cloth sending device to perform dry-wet mixing through the guide roller assembly, so that part of the moisture of the first semi-finished cloth is transferred to the initial cloth, the liquid content is reduced again, and a second semi-finished cloth is obtained, and the liquid content of the second semi-finished cloth is 20-70%; Step 4, the second semi-finished cloth output from the dry-wet mixed roller enters the liquid storage area between the first roller and the dye liquid roller, and the cloth carrying low liquid water content is subjected to dye liquid padding treatment so that the cloth carries the dye liquid; Step 5, receiving the second semi-finished fabric through a drying, color fixing and shaping device and performing drying and shaping treatment; Step 6: Using the first cloth collecting device to collect the second semi-finished cloth after drying and shaping, perform finished product collection operation.

[0022] In one of the solutions of the present invention, there is further provided between step 1 and step 2: Step 1a, guiding the initial fabric after dry-wet mixing into a water-washing agent applying device through a guide roller assembly, so that the initial fabric is evenly provided with water-washing aid; Step 1b, collecting the initial fabric after the washing aid is applied by a second fabric collecting device, and subjecting the initial fabric to a pre-treatment for a certain period of time, wherein the pre-treatment is static or rotating stacking; Step 1c: conveying the initial cloth to the washing device for washing through a second cloth sending device.

[0023] In one embodiment of the present invention, a water squeezing roller is arranged before the input end of the dry-wet mixing roller. The step 3 comprises: The first semi-finished fabric outputted from the washing device is inputted into the squeezing roller, and the squeezing roller and the first roller are pressed to reduce the moisture content of the first semi-finished fabric for a second time; The first semi-finished cloth output from the squeezing roller is mixed with the initial cloth sent by the first cloth sending device for dry and wet squeezing, so that the moisture content of the first semi-finished cloth is reduced for the third time.

[0024] In one embodiment of the present invention, a leveling roller is arranged behind the last dye liquor roller. The step 5 also includes: The second semi-finished cloth output from the dye liquid roller enters between the first roller and the leveling roller, and the cloth carrying moisture and dye liquid is pressed again to make the cloth carry the dye liquid more evenly.

[0025] In one embodiment of the present invention, step 4 further comprises: The second semi-finished cloth output from the dry-wet mixed nip roller enters the liquid storage area, and the cloth carrying low liquid content is padded with dye solution and fixing agent, so that the cloth carries the dye solution and fixing agent; There are two liquid storage areas, the first liquid storage area contains dye solution, and the second liquid storage area contains auxiliary agent. The dye solution rollers at corresponding positions are divided into two groups, and reactive dyes and fixing agents are applied to the fabric in turn, and the liquid amount of the fabric after dry-wet mixing and before the reactive dye is applied is controlled to be less than 60%, the liquid amount of the fabric after the reactive dye is applied is less than 90%, and the liquid amount of the fabric after the fixing agent is applied is less than 120%.

[0026] The continuous water washing and dyeing equipment and method based on the satellite type pressing device of the present invention can achieve the following technical effects: 1. The continuous dyeing equipment of the present invention is provided with a water lotion applying device, and the water lotion is applied to the cloth before washing, and the cloth is collected and stacked after the water lotion is applied. The long-term stacking can prolong the contact time between the water lotion and the cloth, so that these slurries and oils are fully swollen, which is conducive to easier separation from the cloth during washing, and cleaner cleaning.

[0027] 2. During the operation of the previous roll of fabric entering the washing device, the next roll of fabric is collected by the first fabric collecting device and then transferred to a predetermined position to wait. This waiting time effectively prolongs the contact time between the washing agent and the fabric.

[0028] 3. The present invention combines a water squeezing roller and a dry-wet mixed squeezing roller to ensure that the amount of liquid on the cloth after washing and before dyeing is sufficiently low, so the cloth can be dyed without drying after washing, and the pre-treatment washing process and the dyeing process are organically connected together through a satellite squeezing device, which saves energy and reduces emissions while reducing equipment and site occupation.

[0029] 4. Based on the rolling principle of the satellite rolling device, the first roller of the present invention is provided with multiple groups of dry-wet mixing rollers, multiple dyeing rollers, multiple homogenizing rollers, and multiple water squeezing rollers. Each of the dry-wet mixing rollers, dyeing rollers, homogenizing rollers, and water squeezing rollers is sequentially arranged in a satellite shape around the first roller, and the fabric can be subjected to multiple rolling treatments at each link. The present invention can reduce the amount of fabric liquid before applying the dyeing liquid, and the final dyeing liquid has better permeability and uniformity. At the same time, since multiple rollers are distributed on the outer circle of the first roller, less equipment is required and the tension is easier to control.

[0030] 5. By configuring the second roller as an integral second roller body and a second mandrel, which is different from the traditional roller body having a hollow structure inside, the mechanical strength of the roller is ensured, and by configuring the first pressure devices on the left and right and the second pressure devices on the left and right, the left, middle 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 devices on the left and right can be adjusted independently or simultaneously. When the pressure (liquid carrying rate) of the left, middle and right sides of the product is inconsistent, the pressure (liquid carrying rate) of the left, middle 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 pressure of the left, middle and right sides, which is a significant improvement.

[0031] 6. After the liquid bag or the air bag is pressurized, the second roller body is propped up. When the first roller and the second roller are pressed together, the second roller body will move in the opposite direction of the pressure of the first pressure device due to the reaction force of the first roller, but the second mandrel remains stationary under the pressure of the first pressure device. The through hole can slide in the axial direction of the power transmission bolt to position and guide the second roller body and simultaneously transmit power from the second roller body to the second mandrel, and at the same time, avoid damage caused by the air bag or liquid bag connected to the second mandrel rotating relative to the second roller body.

[0032] 7. Annular tube bags are sleeved on the outer ends of the shaft ends 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 flexural 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.

[0033] 8. 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, and 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. BRIEF DESCRIPTION OF THE DRAWINGS

The continuous dyeing equipment of the present invention is provided with a water lotion applying device 30, which applies water lotion to the cloth before washing, and collects and stacks the cloth after the water lotion is applied. A long time of stacking can prolong the contact time between the water lotion and the cloth, so that the slurry and oil agent are fully swollen, which is conducive to easier separation from the cloth during washing and cleaner cleaning.

[0048] 2. During the operation of the previous roll of fabric entering the washing device 60, the next roll of fabric is collected by the second fabric collecting device 80 and then transferred to a predetermined position for waiting. This waiting time effectively prolongs the contact time between the washing agent and the fabric.

After being output from the washing device 60, the cloth before entering the first roller 221 and the dry-wet mixed roller 2311 is squeezed again, so that the moisture carried by the cloth before entering the first roller 221 and the dry-wet mixed roller 2311 is further reduced, so that the permeability and uniformity of the dye solution on the cloth are better, thereby improving the quality of the product.

[0051] 3. The present invention combines a water squeezing roller and a dry-wet mixed squeezing roller to ensure that the amount of liquid on the cloth after washing and before dyeing is sufficiently low, so the cloth can be dyed without drying after washing, and the pre-treatment washing process and the dyeing process are organically connected together through a satellite squeezing device, which saves energy and reduces emissions while reducing equipment and site occupation.

[0052] Example 4 In traditional technologies, the mechanical strength of the rollers is either 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.

[0053] Therefore, based on the above-mentioned embodiment 1, this embodiment provides a continuous washing-dyeing device based on a satellite-type pressing device, wherein the second roller assembly 23 further includes a third bearing 235, a second pressure device 236, and a second sliding device 237; The second roller 231 includes a second roller body 2301 and a second mandrel 2302 located inside the second roller body 2301. The second mandrel 2302 is sleeved inside the second roller body 2301. The middle part of the second mandrel 2302 is connected to or integrally formed with the inner circle of the second roller body 2301. The outer diameters of both ends of the second mandrel 2302 are smaller than the inner diameter of the second roller body 2301. Both ends of the second roller body 2301 are equipped with left and right second bearings 232 and left and right second bearing seats 238 for supporting the second roller body 2301, and the second bearing seats 238 are connected to the first sliding device 234 and the first pressure device 233; The pressure of the first pressure device 233 is applied to the two ends of the second roller body 2301 through the left and right second bearings 232 toward the first roller 221; Both ends of the second core shaft 2302 are equipped with left and right third bearings 235 and left and right third bearing seats 239 for supporting the second core shaft 2302, and the third bearing seats 239 are connected to the second sliding device 237 and the second pressure device 236; The pressure of the second pressure device 236 is applied to the middle part of the second roller body 2301 through the second mandrel 2302 toward the first roller 221; The first sliding device 234 and / or the second sliding device 237 are slide rails, slider devices or corresponding bearing seat limiting fixing parts; The first pressure device 233 and the second pressure device 236 respectively drive the second roller body 2301 and the second core shaft 2302 to slide following the first sliding device 234 and the second sliding device 237, so that the second roller 231 can be pressed together with the first roller 221 in a detachable manner under the drive of the first pressure device 233 and the second pressure device 236.

[0054] The principle of this embodiment is described as follows: Since the second roller body 2301 and the second mandrel 2302 are connected or integrated; The pressure of the first pressure devices 233 on the left and right respectively acts on the two ends of the second roller body 2301, and the pressure of the second pressure devices 236 on the left and right acts on the middle part of the second roller body 2301 through the middle part of the second mandrel 2302, that is, the pressure of the first pressure devices 233 on the left and right and the pressure of the second pressure devices 236 on the left and right both act on the second roller body 2301 in the same direction, and the second roller body 2301 is subjected to the combined force of the first pressure device 233 and the second pressure devices 236 on the left and right, without pressure loss, so that the second roller body 2301 can obtain a larger pressure, and thus obtain a lower liquid carrying rate; At the same time, since the pressure of the first pressure device 233 on the left and the pressure of the second pressure device 236 on the left and can be adjusted independently or simultaneously, when the pressure (liquid carrying rate) of the left, middle and right sides of the product is inconsistent, the pressure (liquid carrying rate) of the left, middle and right sides of the product can be made consistent by adjusting the pressure of the corresponding parts to ensure product quality.

[0055] In this embodiment, the continuous washing-dyeing equipment based on the satellite-type pressing device has the following technical effects: 1. The mechanical strength of the roller is ensured by configuring the second roller 231 as an integral second roller body 2301 and a second mandrel 2302. By configuring the first pressure devices 233 on the left and the second pressure devices 236 on the left and the right, the left, middle and right parts of the second roller body 2301 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 233 and the pressure of the second pressure devices 236 on the left and the right can be adjusted independently or simultaneously. When the pressure (liquid carrying rate) of the left, middle and right parts of the product is inconsistent, the pressure (liquid carrying rate) of the left, middle and right parts of the product can be consistent by adjusting the pressure of the corresponding parts, thereby ensuring product quality and realizing simple adjustment of the pressure of the left, middle and right parts, which is a significant improvement.

[0056] In one application scenario of this embodiment, the end shaft of the first roller 221 is connected to the power device 2424, the second roller 231 and the end shaft of the first roller 221 are connected with gears, and the power is transmitted to the second roller 231 through the gears; The second pressure device 236 is a hydraulic cylinder or a pneumatic cylinder or an airbag assembly, and the hydraulic station or a compressed air source is connected to the hydraulic cylinder or the pneumatic cylinder or the airbag through a pipeline; Also, since the roller body has a certain yield strength and the pressure of each pressure device cannot be increased infinitely, in order to reduce the pressure of the first pressure device 233 and the second pressure device 236, the outer cylindrical surface of the roller body is pre-machined into a smaller middle-height shape to meet the minimum middle-height requirement, that is, the diameter of the outer cylindrical surface of the first roller body and the second roller body 2301 decreases slightly from the middle to the two ends (for example, the middle height is 0.1mm).

[0057] In one application scenario of this embodiment, the principle and structural composition of each of the fourth roller assemblies 32 and / or the sixth roller assembly 65 are the same as those of the second roller assembly 23; or, each of the fourth roller assemblies 32 and / or the sixth roller assembly 65 is a traditional roller assembly; In one of the application scenarios of this embodiment, the principle and structural composition of each of the third roller assemblies 31 and / or the fifth roller assembly 64 are the same as those of the first roller assembly 22; or, each of the third roller assemblies 31 and / or the fifth roller assembly 64 is a traditional roller assembly.

The left and right sections of the tubular airbag or liquid bag are connected through the inside of the second mandrel 2302, and the air inlet end or the liquid inlet end is arranged at the left end or / and the right end of the second mandrel 2302. 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 mandrel 2302, and uses a pressure regulating device alone; In the pressurized state, the pressure of the tubular airbags or liquid bags at both ends is the same, and the pressure can be adjusted, and 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; The airbag or liquid bag props up the second roller body 2301 after being pressurized, and the pressure of the first pressure device 233 is evenly transmitted to the second roller body 2301 through the second mandrel 2302-the airbag or liquid bag, and then transmitted to the first roller 221. By adjusting the pressure difference between the airbag or liquid bag at both ends and the middle part, the height of the second roller body 2301 is adjusted to offset the flexural deformation of the second roller 231 caused by the first roller 221 and the second roller 231 being pressed together; One or more threaded holes are radially arranged at both ends of the second core shaft 2302, and one or more through holes are radially arranged at both ends of the second roller body 2301. Power transmission bolts are arranged 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 2301 can slide in the axial direction of the power transmission bolts.

[0059] In this embodiment, the continuous washing-dyeing equipment based on the satellite-type pressing device has the following technical effects: 1. After the liquid bag or the air bag is pressurized, the second roller body 2301 is propped up. When the first roller 221 and the second roller 231 are pressed together, due to the reaction force of the first roller 221, the second roller body 2301 will move in the opposite direction of the pressure of the first pressure device 233, but the second mandrel 2302 remains stationary under the pressure of the first pressure device 233. The through hole can slide in the axial direction of the power transmission bolt to position and guide the second roller body 2301 and transmit power from the second roller body 2301 to the second mandrel 2302. At the same time, it avoids the air bag or the liquid bag connected to the second mandrel 2302 from rotating relative to the second roller body 2301 and causing damage.

[0079] Example 8 In the existing equipment, the cloth carrying the dye liquid runs close to the outer circle of the first roller 221, and air sometimes exists between the cloth and the outer circle of the first roller 221. For densely woven cloth, the air is not easy to be discharged, and bubbles are formed at the pressing point of the first roller 221 and the second roller 231. The existence of these bubbles will cause the dye liquid on the surface of the cloth to be unevenly distributed, forming strip marks on the surface of the cloth, affecting the cloth surface effect.

[0080] Therefore, on the basis of the aforementioned embodiment 1, this embodiment provides a continuous washing and dyeing equipment based on a satellite-type pressing device, wherein an exhaust roller 28 is arranged between two adjacent second rollers 231, and both ends of the exhaust roller 28 are rotatably arranged on the frame 21, and the exhaust roller 28 is arranged close to the outer circle of the first roller 221, so that the cloth is separated from the first roller 221 after being pressed by the first roller 221 and the previous second roller 231, and passes through the exhaust roller 28 at the corresponding position, so as to create a gap between the cloth and the first roller 221 to exhaust air, and the cloth after passing through the exhaust roller 28 enters between the first roller 221 and the next second roller 231 to be pressed again.

[0081] In this embodiment, the continuous washing-dyeing equipment based on the satellite-type pressing device has the following technical effects: 1. Through the setting of the exhaust roller 28, the cloth can be separated from the first roller 221 after being pressed by the first roller 221 and the previous second roller 231, and pass through the exhaust roller 28 at the corresponding position, and then enter between the first roller 221 and the next second roller 231, instead of being attached to the surface of the first roller 221. When being pressed again, the extruded bubbles can be discharged from the gap between the cloth and the roller surface of the first roller 221, so that the dye liquid on the surface of the cloth can be evenly distributed, ensuring the dyeing effect of the cloth.

[0082] In one application scenario of the present embodiment, three second rollers 231 are arranged in the circumferential direction of the first roller 221, and the three second rollers 231 are respectively pressed and arranged with the outer circumferential surface of the first roller 221 through the corresponding first pressure devices 233 and the second pressure devices 236. The substrate passes between the first roller 221 and each of the second rollers 231 in sequence, and is continuously pressed and operated three times by the first roller 221 and each of the second rollers 231. The cloth enters the first roller 221, circles and follows the first roller 221, enters between the first second roller 231 and the first roller 221, is pressed for the first time, then leaves the first roller 221, and passes over the first exhaust roller 28, then enters between the second second roller 231 and the first roller 221, is pressed again, and after being pressed, the cloth leaves the first roller 221, passes over the second exhaust roller 28, then enters between the third second roller 231 and the first roller 221, is pressed for the third time, and then is output to the next process for drying, color fixing, shaping, and the like.

[0083] Example 9 like Figure 4 and 5 As shown, on the basis of any one of embodiments 1-8, the first material collecting device 40 is a conveyor belt device, the conveyor belt device at least includes a conveyor belt 401, a conveyor belt support wheel 402 and a conveyor belt 401 power mechanism, and the first material collecting device 40 is arranged between the material from the first roller 221 and the Nth or (NY)th second roller 231 to the material trough 272 or the liquid storage area 27 after the material is led out; The first cloth collecting device 40 is used to allow the cloth to be drawn out from between the first roller 221 and the Nth or (NY)th second roller 231 and then fall from top to bottom onto the conveyor belt 401, and be conveyed forward along with the conveyor belt 401. The linear speed of the conveyor belt 401 is not greater than the speed of the main machine, so that the cloth can be stacked on the conveyor belt 401 after being stretched.

[0084] In this embodiment, the following technical effects are achieved: 1. A large amount of fabric can be stored, and long-term continuous production can be achieved. Moreover, since the conveyor belt 401 is used as the first fabric collecting device 40, the fabric is naturally stacked on the conveyor belt 401, and the fabric is subjected to less tension, which is more suitable for knitted fabric products with greater elasticity.

[0085] Example 10 like Figure 4 and 5As shown, on the basis of any one of Examples 1-8, the first cloth collecting device 40 is a lifting wheel group type sending device, and the lifting wheel group type sending device at least includes a frame 21, a fixed wheel group, a lifting wheel group and a counterweight device 408; the fixed wheel group includes a plurality of fixed wheels 403, each of which is rotatably connected to a fixed beam 404, and the fixed beam 404 is fixedly connected to the frame 21; the lifting wheel group includes a plurality of lifting wheels 405, each of which is rotatably connected to a lifting beam 406, and the lifting beam 406 is slidably connected to the frame 21 through a sliding device, and the sliding device is a sliding wheel 407; each of the fixed wheels 403 and each of the sliding wheels 407 are arranged in a staggered manner front and back, and the fixed beam 404 and the fixed wheels 403 are arranged above the first cloth collecting device 40; The first cloth collecting device 40 is arranged before the material trough 272 after the cloth is led out from between the first roller 221 and the Nth or (NY)th second roller 231; the cloth enters the first cloth collecting device 40 after being led out from between the first roller 221 and the Nth or (NY)th second roller 231, and the cloth crosses through each of the fixed wheels 403 and each of the sliding wheels 407 in sequence; The counterweight device 408 is configured to pull the sliding beam and the sliding wheel 407 to a position above the first cloth collecting device 40, so that under the tension of the cloth, the sliding beam and the sliding wheel 407 move downward following the sliding device, so that the cloth obtains a constant tension; the counterweight device 408 is a pneumatic cylinder or a hydraulic cylinder, which is used to adjust the pressure of the pneumatic cylinder or the hydraulic cylinder to obtain a suitable tension for the cloth.

[0086] In this embodiment, the following technical effects are achieved: 1. In order to store more cloth, more fixed wheels 403 and sliding wheels 407 may be provided, or more rows of fixed wheels 403 and sliding wheels 407 may be provided, or / and the up and down sliding stroke may be lengthened; and a lifting wheel group type sending device is adopted, so that the cloth is always in a state of constant tension on the first cloth collecting device 40, which is more suitable for woven cloth products with less elasticity.

[0087] Embodiment 11 In the existing scheme, the fabric must be treated with sizing or oiling agent during the weaving process before it can be woven normally. In this process, the fabric will carry sizing or lubricating oil, which is not conducive to continuous dyeing and must be removed before dyeing. The traditional way is to first wash the fabric in a traditional washing machine, then dry it, and then dye it. This process has problems such as many equipments, large floor space, and high energy consumption.

[0088] The previously applied "CN115928352A, a constant tension washing machine, a method for reducing the amount of liquid carried and a continuous dyeing method" can reduce the amount of liquid carried after washing. However, since the cloth will inevitably be stretched and lengthened during the washing process, the cloth will pile up before entering the washing tank. Although a cloth storage tank device is provided to stack these cloths, the amount that can be piled up is limited. Under long-term continuous production conditions, the cloth will pile up more and more, and too much cloth will not be able to be piled up. In addition, the tension of the piled cloth is not constant, and it is difficult to stack it neatly, causing the cloth to swing left and right, making it difficult to carry out normal production.

[0089] At the same time, since there is only one second roller assembly in each set of rolling devices, there is only one roller for rolling when rolling water or dyeing liquid, and the final liquid volume is high and the uniformity is poor, which is easy to cause finished product defects. If multiple sets of rolling devices are set up continuously, it will cause problems such as too many equipment and difficult to control tension. In addition, there is no independent device for applying water washing agent in the process flow. Due to continuous production and limited washing time, the slurry and oil agent carried by the cloth are difficult to completely swell into the water, which is easy to cause unclean washing.

[0090] Therefore, this embodiment provides a continuous water washing-dyeing method based on a satellite type pressing device, which can be implemented by the continuous water washing-dyeing device based on a satellite type pressing device of any one of the above embodiments 1-10, and the method includes: Step 1: Sending the initial fabric to between the first roller and each dry-wet mixing roller through the first fabric sending device, so that the initial fabric and the liquid-containing fabric output from the washing device are mixed in dry and wet conditions, so that the initial fabric is hydrated; wherein the liquid-containing fabric that enters initially is the lead fabric, and the liquid-containing fabric that enters subsequently is the first semi-finished fabric after washing; Step 2, guiding the initial cloth after dry-wet mixing into the washing device through the guide roller assembly, washing and rolling by the rollers corresponding to the last group of the fifth roller assembly and the sixth roller assembly, reducing the amount of liquid for the first time, and obtaining the first semi-finished cloth, wherein the amount of liquid in the first semi-finished cloth is 30-120%; Step 3, guiding the first semi-finished cloth and the initial cloth sent by the first cloth sending device to perform dry-wet mixing through the guide roller assembly, so that part of the moisture of the first semi-finished cloth is transferred to the initial cloth, the liquid content is reduced again, and a second semi-finished cloth is obtained, and the liquid content of the second semi-finished cloth is 20-70%; Step 4, the second semi-finished cloth output from the dry-wet mixed roller enters the liquid storage area between the first roller and the dye liquid roller, and the cloth carrying low liquid water content is subjected to dye liquid padding treatment so that the cloth carries the dye liquid; Step 5, receiving the second semi-finished fabric through a drying, color fixing and shaping device and performing drying and shaping treatment; Step 6: Using the first cloth collecting device to collect the second semi-finished cloth after drying and shaping, perform finished product collection operation.

[0091] In this embodiment, the continuous washing-dyeing method based on the satellite-type pressing device has the following technical effects: 1. The fabric can be subjected to the pressing treatment in multiple links. The multiple pressing treatments of the present invention can reduce the amount of liquid on the fabric before applying the dye solution, and finally the permeability and uniformity of the dye solution are better. At the same time, since multiple rollers are distributed on the outer circle of the first roller, less equipment is required and the tension is easier to control.

[0092] 2. It has both pre-treatment washing and dyeing functions, and can continuously perform pre-treatment washing and dyeing of fabrics. It occupies a small area and has low energy consumption in the production process. It is not only energy-saving and environmentally friendly, but also can effectively improve production efficiency.

[0093] Example 12 On the basis of Example 11, the following steps are further provided between step 1 and step 2: Step 1a, guiding the initial fabric after dry-wet mixing into a water-washing agent applying device through a guide roller assembly, so that the initial fabric is evenly provided with water-washing aid; Step 1b, collecting the initial fabric after the washing aid is applied by a second fabric collecting device, and subjecting the initial fabric to a pre-treatment for a certain period of time, wherein the pre-treatment is static or rotating stacking; Step 1c: conveying the initial cloth to the washing device for washing through a second cloth sending device.

[0094] In this embodiment, the continuous washing-dyeing method based on the satellite-type pressing device has the following technical effects: 1. A water-washing agent applying device is provided in the process flow of the present invention, and the water-washing agent is applied to the cloth before washing, and the cloth is collected and stacked after the water-washing agent is applied. The long-term stacking can prolong the contact time between the water-washing agent and the cloth, so that these slurries and oils are fully swollen, which is conducive to easier separation from the cloth during washing, and cleaner cleaning.

[0095] 2. During the operation of the washing device after the previous roll of cloth enters the washing device, the next roll of cloth is collected by the first cloth collecting device and then transferred to a predetermined position to wait. This waiting time effectively prolongs the contact time between the washing agent and the cloth. Since the production is continuous, the first roll of cloth and the last roll of cloth can be waste or reusable cloth rolls.

[0096] Example 13 On the basis of Example 11 or 12, a water squeezing roller is arranged before the input end of the dry-wet mixed squeezing roller. The step 3 comprises: Step 3a, inputting the first semi-finished fabric outputted from the washing device into the squeezing roller, and squeezing the first semi-finished fabric with the squeezing roller and the first roller, so as to reduce the moisture content of the first semi-finished fabric for a second time; Step 3b: performing dry-wet mixing of the first semi-finished cloth outputted from the squeezing roller and the initial cloth sent by the first cloth sending device, so that the moisture content of the first semi-finished cloth is reduced for the third time.

[0097] In this embodiment, the continuous washing-dyeing method based on the satellite-type pressing device has the following technical effects: 1. After being output from the washing device, the first semi-finished fabric before entering the first roller and the dry-wet mixed roller is squeezed again, so that the moisture carried by the fabric before entering the first roller and the dry-wet mixed roller is further reduced, so that the permeability and uniformity of the dye solution on the first semi-finished fabric are better, and the quality of the product is improved; and after multiple squeezing, the liquid content of the fabric is effectively reduced, and the heating time required in the subsequent drying and fixing process steps is shorter, which can effectively reduce energy consumption and be more environmentally friendly.

[0098] Embodiment 14 On the basis of Example 11 or 12, a leveling roller is arranged behind the last dye liquor roller, and step 5 further comprises: The second semi-finished cloth output from the dye liquid roller enters between the first roller and the leveling roller, and the cloth carrying moisture and dye liquid is pressed again to make the cloth carry the dye liquid more evenly.

[0099] In this embodiment, the continuous washing-dyeing method based on the satellite-type pressing device has the following technical effects: 1. After passing through the first roller and the dye liquid roller, the second semi-finished fabric carrying moisture and dye liquid is subjected to a pressing treatment again, so that the second semi-finished fabric carries the dye liquid more evenly, avoids color spots on the second semi-finished fabric, and improves the quality of the product; Embodiment 15 Based on Example 11 or 12, step 4 further includes: The second semi-finished cloth output from the dry-wet mixed nip roller enters the liquid storage area, and the cloth carrying low liquid content is padded with dye solution and fixing agent, so that the cloth carries the dye solution and fixing agent; There are two liquid storage areas, the first liquid storage area contains dye solution, and the second liquid storage area contains auxiliary agent. The dye solution rollers at corresponding positions are divided into two groups, and reactive dyes and fixing agents are applied to the fabric in turn, and the liquid amount of the fabric after dry-wet mixing and before the reactive dye is applied is controlled to be less than 60%, the liquid amount of the fabric after the reactive dye is applied is less than 90%, and the liquid amount of the fabric after the fixing agent is applied is less than 120%.

[0100] In this embodiment, the continuous washing-dyeing method based on the satellite-type pressing device has the following technical effects: 1. Controlling the amount of liquid on the fabric within a predetermined range can effectively reduce the time required for the subsequent drying process and reduce the overall energy consumption of the equipment; at the same time, it can reduce the risk of disordered migration of dyes at high temperatures due to excessive liquid, avoid uneven dyeing or color spots, and ensure product quality.

[0101] Example 16 See also Fig.12 Based on Example 11 or 12, a second washing device and a second set of drying, color fixing and shaping devices are further provided in front of the first cloth collecting device, and step 6 further includes: Step 6a, performing a secondary water washing operation on the fabric after the drying and setting treatment to remove the dye or additive remaining on the surface of the fabric; Step 6b: performing a secondary drying and shaping operation on the fabric after the secondary washing.
