[0080] Similarly, after being pressed by the fourth pressure device 130, the two ends of the second mandrel 122 will inevitably be deformed or tend to be deformed towards the pressure direction of the fourth pressure device 130, and the fourth sliding device 131 can make the two ends of the second mandrel 122 slide or swing along the fourth sliding device 131. Alternatively, the fourth sliding device 131 is a limiting device of the fourth bearing seat 137, which prevents the second mandrel 122 from rotating the fourth bearing seat 137 and further damaging the fourth pressure device 130.

[0081] In order to realize the continuous pressing of the cloth 70, referring to the attached drawings Figures 3-8 In one embodiment of the utility model, the second roller assembly is provided with multiple second rollers, and the multiple second rollers are divided into one or more dry-wet mixing rollers 1211, one or more dye rollers 1212, one or more homogenizing rollers 1213, or one or more water rollers. The dry-wet mixing rollers 1211, the dye rollers 1212, the homogenizing rollers 1213, and the water rollers are arranged in a satellite shape around the first roller in sequence. The multiple second rollers 120 are respectively pressed with the outer cylindrical surface of the first roller 110 through the corresponding third pressure device 123 and the fourth pressure device 130. The base material passes between the first roller 110 and each second roller 120 and is subjected to multiple pressing operations by the first roller 110 and each second roller 120.

[0082] Further, the dry-wet mixing roller 1211 is located between the first cloth sending device and the satellite pressing device, and performs dry-wet mixing processing on the dry cloth and the wet cloth passing between the first roller and each dry-wet mixing roller 1211.

[0083] The dye roller 1212 is located behind the last dry-wet mixing roller 1211 and in front of the first homogenizing roller 1213.

[0084] The dye roller 1212 performs dye pressing processing on the cloth carrying low liquid water after passing through the first roller and the dry-wet mixing roller 1211, so that the cloth carries the dye.

[0085] The homogenizing roller 1213 is located behind the last dyeing roller 1212, and the cloth carrying water and dyeing liquid is subjected to pressure again after passing through the first roller and the dyeing roller 1212, so that the cloth carrying the dyeing liquid is more uniform; the cloth subjected to pressure by the homogenizing roller 1213 is output from the satellite type pressure device to the next process;

[0086] The water-rolling roller is located at the front end of the satellite type pressure device and between the last homogenizing roller 1213 or the last dyeing roller 1212 and the first dry-wet mixed rolling roller 1211, and the cloth is subjected to water-rolling again before entering the first roller and the dry-wet mixed rolling roller 1211 after being output from the water washing device, so that the water carried by the cloth before entering the first roller and the dry-wet mixed rolling roller 1211 is further reduced.

[0087] Referring to the drawings, Figure 5 In an embodiment of the utility model, two adjacent second rollers 120 are provided with an exhaust roller 54, both ends of the exhaust roller 54 are rotatably arranged on the rack 10, and the exhaust roller 54 is arranged close to the outer wall of the first roller 110.

[0088] After the cloth 70 is subjected to pressure by the first roller 110 and the previous second roller 120, the cloth 70 is separated from the first roller 110, passes through the exhaust roller 54 at the corresponding position, and is not attached to the surface of the first roller 110, so that a gap is formed between the cloth 70 and the first roller 110, and then the cloth 70 enters the first roller 110 and the next second roller 120 again and is subjected to pressure again.

[0089] The cloth 70 carrying the dyeing liquid is attached to the outer circle of the first roller 110, and sometimes air exists between the cloth 70 and the outer circle of the first roller 110. For the cloth 70 with a dense weave, the air is not easy to exhaust, and air bubbles are formed at the pressure joint of the first roller 110 and the second roller 120. The existence of the air bubbles causes the dyeing liquid on the surface of the cloth 70 to be unevenly distributed, and strip marks are formed on the surface of the cloth 70, which affects the cloth surface effect.

[0090] Through the arrangement of the exhaust roller 54, after the cloth 70 is subjected to pressure by the first roller 110 and the previous second roller 120, the cloth 70 is separated from the first roller 110, passes through the exhaust roller 54 at the corresponding position, and then enters the first roller 110 and the next second roller 120 again, instead of being attached to the surface of the first roller 110. When the cloth 70 is subjected to pressure again, the air bubbles are exhausted from the gap between the cloth 70 and the roller surface of the first roller 110, and the process is repeated until the cloth 70 is output after being subjected to pressure for multiple times.

[0091] wherein in a specific setting, referring to the attached Figure 6 , the heavy load uniform pressing device can further comprise a first rack 101, a second rack 102, two first roller assemblies, and two second roller assemblies. The first rack and the second rack are adjustably abutted by the Nth pressure device and the Nth sliding device, the two first rollers are respectively rotatably connected with the first rack and the second rack through the first bearing seat at both ends, the two first rollers are adjustably abutted in the horizontal direction by the Nth pressure device and the Nth sliding device following the corresponding rack, and one second roller is arranged in the circumferential direction of each first roller. The four rollers (second roller, first roller, first roller, and second roller) are sequentially arranged in the horizontal direction, and each second roller is pressed on the outer cylindrical surface of the corresponding first roller by the third pressure device and the fourth pressure device.

[0092] referring to the attached Figure 9 , one embodiment of the utility model further includes a scraper assembly 30, the scraper assembly 30 includes a knife holder 31, a scraper blade 32 and a presser foot 33, the scraper blade 32 is pressed and arranged between the knife holder 31 and the presser foot 33 by the presser foot 33, the scraper assembly 30 is rotatably connected with the rack 10 by the knife holder 31, the scraper assembly 30 is arranged at the front side of the first roller 110, the cutting edge of the scraper blade 32 is adjustably pressed on the outer cylindrical surface of the first roller 110, the outer surface of the first roller 110 is provided with a concave-convex textured mesh, the scraper assembly 30 and the first roller 110 form a liquid storage area 23, or the first roller 110 is provided with a trough 27 below, and the second roller 120 is separably and pressingly arranged outside the circumference of the first roller 110.

[0093] The dye solution is transported to the liquid storage area 23 or the trough 27 by the liquid feeding device, the first roller 110 drives the dye solution to rotate, the excess dye solution is scraped off by the scraper blade 32, the cloth 70 passes between the second roller 120 and the first roller 110, and the pressed and rolled cloth 70 carries the dye solution on the surface of the first roller 110 and transfers it to the cloth 70, and the dye solution penetrates into the internal structure of the cloth 70 under the pressure of the third pressure device 123 and the fourth pressure device 130, and the dye rolling process is completed. In order to improve the uniformity of the cloth 70, a plurality of groups of the pressing device of the utility model can be continuously arranged to perform single or multiple dyeing operations on one side or both sides of the cloth 70.

[0094] As one of the embodiments of the utility model, the heavy load uniform rolling device comprises two or more groups of the heavy load uniform rolling device, the two or more groups of the heavy load uniform rolling device are sequentially arranged front and back, or a heating device is connected behind each group of the heavy load uniform rolling device, and the fabric 70 output by the previous group of the heavy load uniform rolling device is heated / dried / processed.

[0095] Further, a trough is arranged below the first second roller through which the fabric passes, and one or more impregnation rollers are arranged in the trough; or a liquid storage area is arranged above the first roller and the first second roller through which the fabric passes.

[0096] With the operation of the first roller, the fabric is sequentially introduced between the first roller and each first+X second roller, between the first roller and the N-Y second roller, and between the first roller and each N second roller, and then the fabric is output from the first roller and the N second roller to the next process for subsequent drying, fixing, setting and the like.

[0097] In this process, the fabric enters between the first roller and each first+X second roller and between the first roller and the N second roller twice, the fabric does not carry the dye liquor when entering for the first time, and the dye liquor obtained by the fabric between the first roller and the first second roller is redistributed on the two layers of fabric under the pressing action of each second roller between the first+X second roller and the N second roller when entering for the second time, so that the liquor retention rate of the finally output fabric is greatly reduced. Moreover, the liquor retention rate of the output fabric is more uniform after multiple pressing, and the penetration of the dye liquor in the fabric is better.

[0098] In the traditional reactive dyeing process, the reactive dye and the alkali agent are simultaneously input into a large trough, and the fabric has a long flow in the trough. The reactive dye is easily hydrolyzed in water in the trough, and the degree of hydrolysis is more intense under alkaline conditions. The hydrolyzed reactive dye cannot be combined with the fabric and finally becomes a floating color, so a large amount of water must be used for cleaning after dyeing to obtain good color fastness. The large trough and long flow are difficult to maintain the balance of the concentration of the reactive dye, so color difference is easily caused. In order to solve this problem, see the attached Figure 8, the heavy load uniform pressing device further comprises a cloth sending device 50 and a plurality of guide roller assemblies, the guide roller assemblies comprise a first guide roller 51 arranged at the entrance of the cloth 70, a second guide roller 52 arranged at the output end of the last second roller 120 through which the cloth 70 passes, and a plurality of third guide rollers 53 for guiding the cloth 70 into the dyeing liquid contained in the trough 27 or the liquid storage area 23, the cloth sending device 50 is used to send the cloth 70 to the first roller 110 and the second roller 120, and the cloth 70 sent out is guided by the plurality of third guide rollers 53 and the first guide roller 51 to the first roller 110 and the second roller 120 for pressing.

[0099] The heavy load uniform pressing device in the embodiment comprises N second roller assemblies (N is an integer equal to or greater than 3), a trough is arranged below the first second roller and the first roller, and one or more impregnation wheels are arranged in the trough, or a liquid storage area is arranged above the first second roller and the first roller, and the liquid storage area is a liquid storage area;

[0100] Further comprising a cloth sending device and one or more first, second and third guide rollers;

[0101] The first guide roller is arranged at the entrance of the cloth and guides the cloth into the first roller and each first+X second roller (X is an integer equal to or greater than 1) in turn;

[0102] The second guide roller is arranged beside the output end of the last first+X second roller, guides the cloth out of the first roller and the last first+X second roller, and leads to the third guide roller;

[0103] One or more third guide rollers guide the cloth into the trough or the liquid storage area, after being impregnated with the dyeing liquid, the cloth is pressed between the first roller and the first second roller, and the cloth is quantitatively dyed after being pressed;

[0104] With the operation of the first roller, the cloth enters the first roller and each first+X second roller in turn again, then enters the first roller and each first+N-Y second roller (Y is an integer greater than or equal to 0) in turn, the first roller and the Nth second roller, and then the cloth is output from behind the first roller and the Nth second roller to the next process for subsequent drying, fixing, shaping and other treatments.

[0105] The first guide roller / second guide roller, third guide roller, first roller and second roller form a closed loop structure, and the first guide roller and the cloth sending device are arranged in the closed loop structure.

[0106] At least two ends between the first roller and the N-Yth second roller are provided with end sealing assemblies and material conveying devices, the material conveying pipe is arranged above the first roller body and the N-Yth second roller body, and the space above the first roller body and the N-Yth second roller body forms a second liquid storage area, and the fixing alkali agent is conveyed to the second liquid storage area through the material conveying pipe.

[0107] After the fabric is pressed between the first roller and the first second roller, a certain amount of reactive dye solution is obtained, and after the fabric passes through the first roller and each 1+Xth second roller, the fabric is subjected to dry-wet mixing and rolling for multiple times to obtain a lower liquid carrying rate, preferably 50-60%, at this time, the liquid carrying rate of the fabric has not reached saturation, and the fabric can still carry more solution;

[0108] Then the fabric enters between the first roller and each N-Yth second roller to obtain a solution of fixing alkali agent, preferably the liquid carrying rate of the fabric at this time is 100-120% (the saturation liquid carrying rate of pure cotton fabric is about 120%), although a part of the reactive dye solution carried by the fabric will fall off and dissolve into the liquid storage area, due to the limited storage capacity of the liquid storage area and the short flow of the fabric in the liquid storage area, which is about 1%-5% of the traditional padder, in the process of high-speed running, the exchange rate of the solution is fast, and the solution exchange can be balanced quickly, so the falling off and hydrolysis of the reactive dye in the liquid storage area is limited, and the product quality is not greatly affected.

[0109] Then the fabric enters between the first roller and the Nth second roller and is pressed again, and the liquid carrying amount of the fabric after being pressed again is more uniform, and the permeability is better. Finally, the fabric is output from the rear of the first roller and the Nth second roller to the next process for subsequent drying, fixing, shaping and the like.

[0110] The third pressure device and the fourth pressure device of the heavy load uniform pressing device are arranged, so that the first roller and the second roller can be adjusted to have a uniform degree while realizing heavy load pressing, and the dry-wet mixing method further reduces the liquid carrying amount, creates conditions for continuous application of fixing alkali agent (only under the premise of a low enough liquid carrying amount, the fixing alkali agent can be continuously applied to the fabric), and because two groups of material grooves or liquid storage areas are arranged in the same device, the reactive dye and the fixing alkali agent can be continuously applied in the same pressing device, the alkali agent and the reactive dye do not contact before being applied to the fabric, the hydrolysis of the reactive dye is reduced, the color difference before and after is reduced, the dye uptake is effectively improved, and the washing load after the fabric is dyed with the reactive dye is reduced, which is conducive to energy saving and environmental protection.

[0111] Because the cloth must be stretched after being guided from the first roller and the first+X second roller to the front of the trough, the cloth will be accumulated in front of the trough after a long time of operation, affecting normal production.

[0112] To solve this problem, see the attached Figure 7 、 8 One embodiment of the utility model also includes cloth storage device, the cloth storage device is set to conveyor belt device or lifting wheel group type cloth storage device or cloth storage tank device; The input end of the cloth storage device is connected with the pressing output end of the first roller assembly and the second roller assembly, and the output end of the cloth storage device is connected with the input port of the trough.

The linear speed of the conveyor belt is not greater than the speed of the main machine, so that the cloth can be stacked on the conveyor belt after being stretched, more cloth can be stored, and continuous production for a long time can be realized.

[0114] Because the conveyor belt is used as the cloth storage device, the cloth is stacked in a natural state on the conveyor belt, the tension on the cloth is small, and the cloth storage device is more suitable for knitted cloth products with greater elasticity.

[0115] The lifting wheel group type cloth storage device includes a frame, fixed wheel groups, lifting wheel groups, counterweight devices, etc.

[0116] The fixed wheel group includes a plurality of fixed wheels, each of which is rotatably connected with a fixed beam, and the fixed beam is fixedly connected with the frame.

[0118] Each of the fixed wheels and the sliding wheels is arranged in front of and behind each other in turn, and the fixed beam and the fixed wheels are preferably arranged at an upper position of the cloth storage device.

[0119] The cloth enters the cloth storage device after being guided from the first roller and the first+X second roller, and the cloth passes through each of the fixed wheels and the sliding wheels in turn.

[0120] In the initial stage of operation, the counterweight device pulls the sliding beam and the sliding wheel to the position above the cloth storage device, and as the machine operates, the cloth is gradually stretched, and under the tension of the cloth, the sliding beam and the sliding wheel slowly move downward along the sliding device, so that the cloth obtains constant tension.

[0121] In order to obtain appropriate tension, the weight of the counterweight device can be set according to requirements, or the counterweight device is a pneumatic cylinder or a hydraulic cylinder, and appropriate tension of the cloth is obtained by adjusting the pressure of the pneumatic cylinder or the hydraulic cylinder.

[0122] In order to store more cloth, more of the fixed wheels and the sliding wheels can be provided, or more rows of the fixed wheels and the sliding wheels can be provided, or / and the up-down sliding stroke can be lengthened.

[0123] Since the lifting wheel group type cloth storage device is adopted, the cloth is always in a state of constant tension on the cloth storage device, and is more suitable for less elastic woven cloth products.

[0124] The cloth storage groove device is a concave arc or a "J" shaped stainless steel groove, and the cloth falls in the cloth storage groove from top to bottom after being guided out from between the first roller and the N-Yth second roller, and after being stretched, the cloth can be stacked in the cloth storage groove, more cloth can be stored, and long-time continuous production can be realized, but this way will accumulate more and more cloth with the increase of operation time, and is not suitable for too large production continuous production.

Figure 5The rear of the heavy load uniform rolling device is further provided with a second group of rolling mills, the previous group of the heavy load uniform rolling device applies active dye solution to the cloth, and lower liquid rate is obtained, preferably the liquid rate is 50-60%, the liquid rate of the cloth is not saturated, so after entering the second group of rolling mills, the cloth can still carry more solution, preferably the liquid rate is 100-120% (the saturated liquid rate of pure cotton cloth is about 120%), the solution in the second group of rolling mills is fixing alkali agent, preferably the alkali agent is arranged above the two rolling mills of the second group of rolling mills, the upper part between the two rolling mills of the second group of rolling mills forms a liquid storage area, the cloth runs downward from the upper part between the two rolling mills of the second group of rolling mills, although the active dye solution applied to the cloth by the previous group of the heavy load uniform rolling device will fall off and dissolve into the liquid storage area, but since the storage capacity of the liquid storage area is limited, and the flow of the cloth in the liquid storage area is very short, about one tenth of the traditional rolling mill, in the process of high-speed running, the exchange rate of the solution is relatively fast, and the solution exchange can be balanced quickly, so the falling off and hydrolysis of the active dye in the liquid storage area is limited, and the product quality is not greatly affected.

[0161] One of the specific application examples of the washing and dyeing in the utility model is seen from Figure 3 、 4 The heavy load uniform rolling device at least comprises a rack, one first roller assembly and three second roller assemblies.

[0162] The first roller is rotationally connected with the rack through first bearing seats at two ends of the first roller, three second rollers are arranged in the circumferential direction of the first roller, and the three second rollers are respectively pressed against the outer cylindrical surface of the first roller through corresponding third pressure devices and fourth pressure devices, and the base material passes between the first roller and each second roller in sequence and is subjected to three times of continuous pressing operation by the first roller and each second roller.

[0163] Further, an exhaust roller is arranged between two adjacent second rollers, both ends of the exhaust roller are rotationally arranged on the rack, and the exhaust roller is arranged close to the outer circle of the first roller.

[0164] A trough is arranged below the second roller and the first roller, three impregnation rollers are arranged in the trough, and an ultrasonic oscillation device is arranged on the side wall of the trough.

[0165] End sealing assemblies and material conveying devices are arranged at both ends between the first roller and the second roller, and sealing assemblies are arranged at both ends of the second roller and the first roller.

[0166] The second pressure device is a hydraulic cylinder assembly, and a hydraulic station is connected with the hydraulic cylinder through a pipeline.

[0167] The outer circumferential surface of the first and second roller bodies is coated with a rubber layer.

[0168] The end shaft of the first roller is connected to a power device, and the second roller and the end shaft of the first roller are connected to a gear, and power is transmitted to the second roller through the gear.

[0169] The cloth enters the trough, passes through the impregnation rollers in turn, and is pressed between the impregnation rollers in turn. The last impregnation roller is arranged in pressing with the first roller. The cloth enters the first roller from the last impregnation roller, circulates around and runs along with the first roller, enters between the first roller and the first second roller, and is pressed for the first time. Then the cloth is separated from the first roller and passes above the first exhaust roller. Then the cloth enters between the first roller and the second second roller and is pressed again. After the cloth is pressed, it is separated from the first roller and passes above the second exhaust roller. Then the cloth enters between the first roller and the third second roller and is pressed for the third time. Then the cloth is output to the next process for drying, fixing, shaping and the like.

[0170] The trough contains an active dye solution. After the cloth is extruded by the impregnation rollers, it carries excess dye solution. After being pressed between the first second roller and the first roller, the cloth obtains a certain amount of active dye solution. At this stage, the pressure between the first second roller and the first roller is relatively large, and the cloth can obtain a lower liquid rate, preferably 50%.

[0171] The space above the second second roller and the first roller contains a fixing alkali agent. When the cloth passes between the second second roller and the first roller, it is pressed for the second time, and obtains a certain amount of mixed solution of active dye and fixing alkali agent. At this stage, the pressure between the second second roller and the first roller is relatively small, and the cloth can obtain a higher liquid rate, preferably 100%.

[0172] With the operation of the machine, the cloth enters between the third second roller and the first roller and is pressed for the third time. The third pressing is to further homogenize the solution carried on the surface of the cloth. Preferably, the pressure is not greater than the pressure of the second pressing, so as to avoid extruding the mixed solution carried by the cloth.

[0173] After the cloth is pressed for the third time, it is output to the next process for drying, fixing, shaping and the like.

[0174] During weaving, the cloth must be treated with sizing or oil agent to enable normal weaving. During this process, the cloth carries sizing or lubricating oil, which is not conducive to continuous dyeing and must be removed before dyeing.
