Description

Technical Field

[0001] The invention relates to the technical field of textile printing and dyeing, and in particular to a heavy-load uniform pressing device, a washing device and a dyeing device. Background Art

[0002] During the dyeing process of fabrics, the fabrics need to be rolled with functional solutions such as dyes, and then the fabrics with functional solutions are heated and dried. In order to save subsequent drying energy consumption, the liquid rate after rolling should be as low as possible under the premise of uniform rolling, which requires the rolling device to be able to achieve heavy-load rolling. There are many traditional rolling methods, most of which are pressed together by two or more rollers through the pressure of the roller shaft end. During the pressing process, the pressure of the shaft end will cause the working surface to bend and deform in the opposite direction of the pressure, which can easily cause the product to have uneven thickness or liquid content on the left, middle and right. In order to obtain a more uniform liquid content, the pressure of the roller cannot be too large, resulting in a high liquid content on the fabric, which not only increases the energy consumption during subsequent drying, but also limits its application range.

[0003] The deformation of the roller directly affects the performance of the product, and the liquid carrying rate (rolling residue rate) directly affects the energy consumption of subsequent drying. So far, there is no ideal way to solve the above technical problems.

[0030] Beneficial effects:

[0031] The heavy-load uniform rolling device of the present invention ensures that the second roller has sufficient mechanical strength because the second roller body and the second mandrel are fixedly connected. The pressures of the third pressure devices on the left and right sides act on the two ends of the second roller body respectively, and the pressures of the fourth pressure devices on the left and right sides act on the middle part of the second roller body through the middle part of the second mandrel, that is, the pressures of the third pressure devices on the left and right sides and the pressures of the fourth pressure devices on the left and right sides both act on the second roller body in the same direction. The second roller body is subjected to the combined force of the third pressure device and the fourth pressure devices on the left and right sides without pressure loss, so that the second roller body can obtain a larger pressure and thus obtain a lower liquid carrying rate.

[0032] At the same time, since the pressure of the third pressure device on the left and the pressure of the fourth pressure device 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.

[0033] In the background technology, the mechanical strength of the roller is either insufficient, or it cannot be adjusted independently on the left, center and right sides, or there are defects such as complex structure and heavy machinery. In addition, in order to achieve uniform rolling, additional pressure needs to be applied to offset the flexible deformation of the roller, so a considerable amount of pressure will be lost.

[0034] The present invention ensures the mechanical strength of the roller by configuring the second roller as an integral second roller body and second core shaft, and by configuring the third pressure devices on the left and right and the fourth pressure devices on the left and right, the left, center and right sides of the second roller body are subjected to force simultaneously, which not only ensures the mechanical strength and pressure of the roller, but also realizes simple adjustment of the left, center and right pressures, which is a significant improvement.

[0069] It should be noted that the present embodiment does not specifically limit the structure of the first roller body 111.

In the present embodiment, the second roller 120 is set to a structure in which the second roller body 121 and the second core shaft 122 are integrated.

[0070] As one of the embodiments of the present invention, the first rolling roller 110 assembly also includes a second bearing 117 and a second pressure device. The first rolling roller 110 includes a first roller body 111 and a first mandrel 112.

The second pressure device can drive the middle part of the first roller body 111 to approach the second roller body through the first mandrel 112.

[0071] The first roller assembly in the present embodiment is also configured to have the same structure as the second roller assembly described above, so that the two first rollers 110 and the second rollers 120 that cooperate with each other for pressing can be adjusted from two directions at the same time when in use, so as to better ensure that the gap between the first roller 110 and the second roller 120 is uniform, and avoid the problem of uneven liquid carrying rate of the cloth 70 caused by deformation of one of the first roller 110 and the second roller 120.

[0072] In order to achieve stable adjustment of the gap between the first roller 110 and the second roller 120, one embodiment of the present invention also includes a plurality of sliding devices, each of the pressure devices is equipped with a sliding device, the sliding device includes a slide rail and a slider, the slider is slidably arranged on the slide rail, each of the pressure devices is equipped with a bearing seat assembly, the bearing seat assembly is fixedly connected to the slider on the corresponding sliding device, the ends of the roller body or the core shaft corresponding to each pressure device are respectively supported by the corresponding bearing seat assembly, the pressure device also includes a pressure driving assembly that can drive the bearing seat assembly to slide along the corresponding slide rail through the slider, and the bearing seat assemblies corresponding to the roller body and the core shaft located on the same side are staggered.

[0073] By staggering the first bearing 114 or the third bearing 126 on the same side to the left and right, interference between the two bearing seats can also be avoided. However, under certain size restrictions, it is necessary to stagger the first bearing 114 and the third bearing 126 on the same side to the left and right when setting the bearing position connector to ensure that the first roller body 111 and the second roller body 121 can contact and press fit.

[0074] See attached Figure 1, for the convenience of description and distinction, in the present invention, the third pressure device 123 corresponds to the third sliding device 124 and the third bearing seat assembly, the fourth pressure device 130 corresponds to the fourth sliding device 131 and the fourth bearing seat assembly, and the second pressure device 115 corresponds to the second sliding device 116 and the second bearing seat assembly, wherein the third bearing seat assembly and the fourth bearing seat assembly are respectively provided at the same end of the second roller body 121, and in addition to the second bearing seat 117 for supporting the first spindle 112 at one end of the first roller body 111, a first bearing seat assembly for supporting the first roller body 111 is also provided, wherein in order to avoid mutual interference between the first bearing seat assembly and the third bearing seat assembly, the first bearing seat assembly and the third bearing seat assembly are arranged in a staggered manner, see the attached Figure 1 .

[0075] It can be seen that since the second roller body 121 and the second mandrel 122 are connected or integrally arranged, it is ensured that the second roller 120 has sufficient mechanical strength;

[0076] The pressure of the third pressure devices 123 on the left and right respectively acts on the two ends of the second roller body 121, and the pressure of the fourth pressure devices 130 on the left and right acts on the middle part of the second roller body 121 through the middle part of the second mandrel 122, that is, the pressure of the third pressure devices 123 on the left and right and the pressure of the fourth pressure devices 130 on the left and right both act on the second roller body 121 in the same direction, and the second roller body 121 is subjected to the combined force of the third pressure device 123 and the fourth pressure devices 130 on the left and right, without pressure loss, so that the second roller body 121 can obtain a larger pressure, and thus obtain a lower liquid carrying rate;

[0077] At the same time, since the pressure of the third pressure device 123 on the left and the pressure of the fourth pressure device 130 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.

[0078] In the background technology, the mechanical strength of the roller is either insufficient, or it cannot be adjusted independently on the left, center and right sides, or there are defects such as complex structure and heavy machinery. In addition, in order to achieve uniform rolling, additional pressure needs to be applied to offset the flexible deformation of the roller, so a considerable amount of pressure will be lost.

[0079] The present invention ensures the mechanical strength of the roller by configuring the second roller 120 as an integral second roller body 121 and second core shaft 122, and by configuring the left and right third pressure devices 123 and the left and right fourth pressure devices 130, the left, center and right sides of the second roller body 121 are subjected to force simultaneously, which not only ensures the mechanical strength and pressure of the roller, but also realizes simple adjustment of the left, center and right pressures, which is a significant improvement.

[0080] Similarly, after receiving the pressure of the fourth pressure device 130, the two ends of the second mandrel 122 will inevitably produce deformation or deformation tendency toward the pressure direction of the fourth pressure device 130, and the fourth sliding device 131 can be set to make the two ends of the second mandrel 122 slide or swing along the fourth sliding device 131. Or the fourth sliding device 131 is a limit device of the fourth bearing seat 137 to prevent the second mandrel 122 from driving the fourth bearing seat 137 to rotate, thereby damaging the fourth pressure device 130.

[0081] In order to achieve continuous pressing of the cloth 70, see the attached Figure 3-8 In one embodiment of the present invention, the second roller assembly is provided with a plurality of second rollers, and the plurality of second rollers are divided into one or more dry-wet mixing rollers 1211, and / or one or more dyeing liquid rollers 1212, and / or one or more homogenizing rollers 1213, and / or one or more water-squeezing rollers. Each of the dry-wet mixing rollers 1211, dyeing liquid rollers 1212, homogenizing rollers 1213, and water-squeezing rollers is sequentially arranged in a satellite shape around the first roller. The plurality of second rollers 120 are respectively pressed and set with the outer cylindrical surface of the first roller 110 through the corresponding third pressure device 123 and the fourth pressure device 130. The substrate passes through the first roller 110 and each of the second rollers 120 in turn, and is continuously subjected to multiple pressing operations by the first roller 110 and each of the second rollers 120.

[0082] Furthermore, the dry-wet mixed rolling roller 1211 is located between the first cloth sending device and the satellite pressing device, and performs dry-wet mixed rolling treatment on the dry cloth and the wet cloth passing between the first roller and each of the dry-wet mixed rolling rollers 1211;

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

[0084] The dye liquid roller 1212 performs dye liquid rolling treatment on the cloth carrying low liquid content moisture after passing through the first roller and the dry-wet mixed rolling roller 1211, so that the cloth carries the dye liquid;

[0085] The leveling roller 1213 is located behind the last dye liquid roller 1212, and performs a pressing process again on the cloth carrying moisture and dye liquid after passing through the first roller and the dye liquid roller 1212, so that the cloth carries the dye liquid more evenly; the cloth pressed by the leveling roller 1213 is output from the satellite pressing device to the next process;

[0086] The squeezing roller is located at the front end of the satellite pressing device and between the last homogenizing roller 1213 or the last dye liquid roller 1212 and the first dry-wet mixed rolling roller 1211. The cloth output from the washing device and before entering the first roller and the dry-wet mixed rolling roller 1211 is squeezed again, so that the moisture carried by the cloth before entering the first roller and the dry-wet mixed rolling roller 1211 is further reduced.

[0087] See attached Figure 5 In one embodiment of the present invention, an exhaust roller 54 is arranged between two adjacent second rollers 120 , and both ends of the exhaust roller 54 are rotatably arranged on the frame 10 , and the exhaust roller 54 is arranged close to the outer circular wall of the first roller 110 .

[0088] After being pressed by the first roller 110 and the previous second roller 120, the cloth 70 is separated from the first roller 110 and passes through the exhaust roller 54 at the corresponding position instead of sticking to the surface of the first roller 110, so that a gap is generated between the cloth 70 and the first roller 110, and then enters between the first roller 110 and the next second roller 120 to be pressed again.

[0089] The cloth 70 carrying the dye liquid is running close to the outer circle of the first roller 110, and sometimes there is air between the cloth 70 and the outer circle of the first roller 110. For the densely woven cloth 70, the air is not easy to be discharged, and then bubbles are formed at the pressing point of the first roller 110 and the second roller 120. The existence of these bubbles will cause the dye liquid on the surface of the cloth 70 to be unevenly distributed, and strip marks will be formed on the surface of the cloth 70, affecting the cloth surface effect.

[0090] By setting the exhaust roller 54, the cloth 70 can be separated from the first roller 110 after being pressed by the first roller 110 and the previous second roller 120, pass through the exhaust roller 54 at the corresponding position, and then enter between the first roller 110 and the next second roller 120, instead of being attached to the surface of the first roller 110. When being pressed again, the extruded bubbles can be discharged from the gap between the cloth 70 and the roller surface of the first roller 110, and the cloth 70 is repeatedly pressed for multiple times before being output.

[0091] For specific settings, see the attached Figure 6 The heavy-load uniform rolling device may further include a first frame 101, a second frame 102, two first roller assemblies, and two second roller assemblies. The first frame and the second frame are adjustably abutted against each other through an Nth pressure device and an Nth sliding device. The two first rollers are rotatably connected to the first frame and the second frame through the first bearing seats at both ends of each frame. The two first rollers follow the corresponding frames and are adjustably abutted against each other in the horizontal direction through the Nth pressure device and the Nth sliding device. One second roller is arranged in the circumferential direction of each of the two first rollers. Four rollers (second roller, first roller, first roller, second roller) are arranged in sequence in the horizontal direction. Each second roller is pressed against the outer circumferential surface of the corresponding first roller by the corresponding third pressure device and the fourth pressure device.

[0092] See attached Fig. 9 One embodiment of the present invention further includes a scraper assembly 30, the scraper assembly 30 includes a tool holder 31, a scraper blade 32 and a pressure plate 33, the scraper blade 32 is pressed and arranged between the tool holder 31 and the pressure plate 33 by the pressure plate 33, the scraper assembly 30 is rotatably connected to the frame 10 through the tool holder 31, the scraper assembly 30 is arranged on the front side of the first roller 110, the blade 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 texture, a liquid storage area 23 is formed between the scraper assembly 30 and the first roller 110, or a material trough 27 is provided below the first roller 110, and the second roller 120 is detachably pressed and arranged outside the circumference of the first roller 110.

[0093] The dye solution is transported to the liquid storage area 23 or the material tank 27 through the liquid feeding device, the first roller 110 drives the dye solution to run, and 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 while being pressed, the dye solution carried on the surface of the first roller 110 is adsorbed and transferred to the cloth 70, and penetrates into the internal structure of the cloth 70 under the pressure of the third pressure device 123 and the fourth pressure device 130, completing the dye rolling process. In order to improve the uniformity of both sides of the cloth 70, multiple groups of the pressing devices described in the present invention can be continuously set to perform single or multiple liquid squeezing operations on one side or both sides of the cloth 70.

[0094] As one of the embodiments of the present invention, the heavy-loaded uniform rolling device includes two or more groups of the heavy-loaded uniform rolling devices described in the present invention, and the two or more groups of the heavy-loaded uniform rolling devices are arranged in sequence front and back, or a heating device is connected to the rear of each group of the heavy-loaded uniform rolling devices to heat / dry / shape the cloth 70 output by the previous group of the heavy-loaded uniform rolling devices.

[0095] Furthermore, a material trough is provided below the second roller through which the cloth first passes, and one or more impregnation wheels are provided in the material trough; or a liquid storage area is provided above the second roller through which the cloth first passes and the first roller. One or more third guide rollers guide the cloth into the material trough or the liquid storage area, and then the cloth is pressed by the first roller and the first of the second rollers to obtain a certain amount of dye solution;

[0096] As the first roller operates, the cloth is again introduced in sequence between the first roller and each 1+Xth second rollers - between the first roller and the NYth second rollers - between the first roller and each Nth second roller, and then the cloth is output from between the first roller and the Nth second roller to the next process for subsequent drying, color fixing, shaping and other treatments.

[0097] In this process, the cloth enters between the first roller and each of the 1+X second rollers to between the first roller and the Nth second roller twice. When the cloth enters for the first time, it does not carry the dye liquid. When it enters for the second time, under the pressing action of each of the second rollers between the 1+Xth second rollers to the Nth second roller, the quantitative dye liquid obtained by the cloth between the first roller and the first second roller is redistributed to the two layers of cloth, and the liquid carrying rate of the cloth when it is finally output is greatly reduced. Moreover, after multiple pressings, the liquid carrying rate of the cloth when it is output is more uniform, and the permeability of the dye liquid in the cloth is also better.

[0098] In the traditional reactive dye dyeing process, the reactive dye and the alkali agent are simultaneously input into a larger trough, and the fabric has a long process in the trough. The reactive dye is easily hydrolyzed when it meets water in the trough, and the degree of hydrolysis is more intense under alkaline conditions. The hydrolyzed reactive dye cannot combine with the fabric and eventually becomes a floating color. The fabric must be washed with a large amount of water after dyeing to obtain better color fastness. Larger troughs and longer processes make it difficult to maintain a balanced concentration of reactive dyes, so it is easy to cause color difference before and after. To solve this problem, see the attached Figure 8The heavy-load uniform pressing device also includes a cloth sending device 50 and a plurality of guide roller assemblies, wherein the guide roller assembly includes 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 second roller 120 through which the cloth 70 last passes, and a plurality of third guide rollers 53, wherein the third guide roller 53 is used to guide the cloth 70 to the material trough 27 or the liquid storage area 23 containing the impregnation liquid, and the cloth 70 sending device 50 is used to send the cloth 70 to the first roller 110 and the second roller 120, and the sent cloth 70 is guided to the first roller 110 and the second roller 120 by the plurality of the third guide rollers 53 and the first guide roller 51 to be pressed between the first roller 110 and the second roller 120.

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

[0100] Also includes a cloth sending device / 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 space between the first roller and each 1+Xth second rollers in sequence (X is an integer equal to or greater than 1);

[0102] The second guide roller is arranged beside the output end of the last of the 1+X second rollers, and guides the cloth from between the first roller and the last of the 1+X second rollers to the third guide roller;

[0103] One or more third guide rollers guide the fabric into a material trough or liquid storage area, and after being impregnated with dye solution, the fabric enters between the first roller and the first of the second rollers to be pressed, and a certain amount of dye solution is obtained after the fabric is pressed;

[0104] As the first roller operates, the cloth enters between the first roller and each 1+Xth second rollers in turn again, and then enters between the first roller and each NYth second roller (Y is an integer greater than or equal to 0), and between the first roller and the Nth second roller in turn. Then, the cloth is output from the rear between the first roller and the Nth second roller to the next process for subsequent drying, color fixing, shaping and other treatments.

[0105] A closed loop structure is formed between the first guide roller / the second guide roller, the third guide roller, the first roller and the second roller, and the first guide roller and the cloth sending device are arranged in the closed loop structure.

[0106] Wherein, at least both ends between the first roller and the NYth of the second rollers are provided with end sealing assemblies and feeding devices, the feeding pipe is provided above the first roller body and the NYth of the second roller bodies, and a second liquid storage area is formed above the first roller body and the NYth of the second roller bodies, and the color-fixing alkali agent is transported to the second liquid storage area through the feeding pipe.

[0107] Between the first roller and the first of the second rollers, the cloth is pressed to obtain a quantitative reactive dye solution, and then passed between the first roller and each of the 1+X second rollers, the cloth is pressed multiple times to obtain a lower liquid carrying rate, preferably 50-60%, at which point the liquid carrying rate of the cloth has not reached saturation and can still carry more solution;

[0108] Then the cloth enters between the first roller and each NY-th second roller in turn to obtain a solution of a color-fixing alkali agent. Preferably, the liquid carrying rate of the cloth at this time is 100-120% (the saturated liquid carrying rate of pure cotton cloth is about 120%). Although a part of the active dye solution carried by the cloth will fall off and dissolve into the liquid storage area, 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 1%-5% of that of a traditional roller. During high-speed operation, the exchange rate of the solution is relatively fast, and the balance of the solution exchange can be quickly reached. Therefore, the shedding and hydrolysis of the active dye in the liquid storage area are limited, and will not have a significant impact on the product quality.

[0109] Then the fabric enters between the first roller and the Nth second roller and is pressed again. After the pressing again, the fabric has a more uniform amount of liquid and better permeability. Finally, the fabric is output from the back between the first roller and the Nth second roller to the next process for subsequent drying, color fixing, shaping and other treatments.

[0110] In this embodiment, the third pressure device and the fourth pressure device of the heavy-load uniform rolling device of the present invention are arranged so that the uniformity between the first roller and the second roller can be adjusted while achieving heavy-load rolling. In addition, the amount of liquid is further reduced by the dry-wet mixed rolling method, which creates conditions for the subsequent continuous application of the color-fixing alkali agent (the color-fixing alkali agent can only be applied to the cloth under the premise of a sufficiently low amount of liquid). In addition, since two groups of the material troughs or liquid storage areas are arranged in the same device, the reactive dye and the color-fixing alkali agent can be continuously applied in the same rolling device, and the alkali agent and the reactive dye will not contact each other before being applied to the cloth, thereby reducing the hydrolysis of the reactive dye and reducing the color difference before and after, and can effectively improve the dye uptake rate, thereby reducing the washing load after the reactive dye is dyed, which is beneficial to energy saving and environmental protection.

[0111] Since a plurality of sets of the third guide rollers must be arranged before the material trough after the cloth is led out from between the first roller and the 1+Xth second rollers, the cloth will inevitably be stretched. With long-term operation, the cloth will accumulate in front of the material trough, affecting normal production.

[0112] To solve this problem, see Appendix Figure 7 , 8 One embodiment of the present invention further includes a cloth storage device, which is configured as a conveyor belt device or a lifting wheel group type cloth storage device or a cloth storage trough device; the input end of the cloth storage device is connected to 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 to the input port of the material trough.

[0113] The conveyor belt device in this embodiment includes: a conveyor belt / conveyor belt support wheel / conveyor belt power device, etc. After the cloth is led out from between the first roller and the NYth second roller, it falls from top to bottom onto the conveyor belt and is transported forward with the conveyor belt. The linear speed of the conveyor belt is not greater than the speed of the main machine. Therefore, after the cloth is stretched, it can be stacked on the conveyor belt in a stacked state, so that more cloth can be stored and long-term continuous production can be achieved.

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

[0115] The lifting wheel group type cloth storage device comprises: a frame / a fixed wheel group / a lifting wheel group / a counterweight device and the like.

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

[0117] The lifting wheel group includes a plurality of lifting wheels, each of which is rotatably connected to a lifting beam, and the lifting beam is slidably connected to the frame via a sliding device, and the sliding device is preferably a pulley.

[0118] The fixed wheels and the sliding wheels are arranged alternately front and back in sequence, and preferably the fixed beam and the fixed wheels are arranged above the cloth storage device;

[0119] The cloth is led out from between the first roller and the 1+Xth second rollers and then enters the cloth storage device, and the cloth crosses through each of the fixed wheels and each of the sliding wheels at one time;

[0120] At the beginning of operation, the counterweight device pulls the sliding beam and the sliding wheel to the upper position of the cloth storage device. As the machine runs, the cloth is gradually stretched. Under the tension of the cloth, the sliding beam and the sliding wheel slowly move downward following the sliding device, so that the cloth obtains a constant tension.

[0121] To obtain a suitable tension, the weight of the counterweight device can be set as required, or the counterweight device can be a pneumatic cylinder or a hydraulic cylinder, and the pressure of the pneumatic cylinder or the hydraulic cylinder can be adjusted to obtain a suitable tension for the fabric.

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

[0123] Due to the adoption of the lifting wheel group type cloth storage device, the cloth is always in a state of constant tension on the cloth storage device, which is more suitable for woven cloth products with less elasticity.

[0124] The cloth storage trough device is a concave arc-shaped or "J"-shaped stainless steel trough. The cloth is led out from between the first roller and the NYth second roller and then falls into the cloth storage trough from top to bottom. After the cloth is stretched, it can be stacked in the cloth storage trough in a stacked state. More cloth can be stored and long-term continuous production can be achieved. However, as the operating time increases, more and more cloth will accumulate in this method, which is not suitable for continuous production of too large an output.

[0125] The second aspect of the present invention discloses a heavy-loaded uniform rolling device, comprising an automatic feeding system, wherein the automatic feeding system is divided into a dye liquor feeding system and an auxiliary agent feeding system, and further comprising a plurality of the heavy-loaded uniform rolling devices according to the first aspect, wherein the plurality of the heavy-loaded uniform rolling devices are arranged side by side.

[0132] The circular sealing plate can be slidably mounted on both ends of the first roller body or the second roller body and is arranged close to the elastic layer.

A plurality of springs are annularly distributed between the circular sealing plate and the spring support member. The circular sealing plate, the spring and the spring support member all rotate with the first roller body or the second roller body.

[0133] Under the elastic force of the spring, the circular sealing plate can slidably contact the end surface of the elastic layer. By adjusting the elastic force of the spring, the sealing degree between the circular sealing plate and the end surface of the elastic layer can be adjusted.

[0134] A liquid storage area is formed above the first roller and the second roller and between the circular sealing plates.

[0135] As one of the embodiments of the present invention, circular grooves are provided on the roller surfaces at the left and right ends of the first roller and the second roller, and the two arcs of the circular arc sealing plate are inserted and matched in the circular grooves corresponding to the first roller and the second roller, and the end sealing components above and on the left and right between the first roller and the second roller together constitute the second liquid storage area.

[0137] As one of the embodiments of the present invention, the sealing plate is made of engineering plastic, preferably a Teflon plate or a carbon fiber plate.

[0138] As one of the embodiments of the present invention, the spring or spring sheet of the axial pressure component and / or radial pressure component is connected with a pressure adjusting bolt, and the pressure of the spring or spring sheet is adjusted by adjusting the bolt. Preferably, the axial pressure component and / or radial pressure component is a spring plunger.

[0139] By providing the axial pressure assembly and the radial pressure assembly, it can be ensured that the end of the second roller or the first roller is tightly sealed, which is beneficial to continuous production.

[0140] As one of the embodiments of the present invention, see the attached Figure 1 The material trough or / and the feeding device are also provided with an ultrasonic oscillation device, which is arranged on the side wall of the material trough, and the ultrasonic oscillation device includes an ultrasonic generator, an amp, a transducer and a vibrator; the amp is electrically connected to the ultrasonic generator, and the amp amplifies or reduces the amplitude of the sound wave generator and transmits it to the transducer, and the piezoelectric ceramic in the transducer converts the electrical energy into mechanical energy of vibration, and then the vibrator transmits the vibration to the solution in the material trough through the side wall steel plate of the material trough; the ultrasonic frequency of the ultrasonic oscillation device is between 20-80KHz, and the input power of each group of ultrasonic oscillation devices is between 2-30KY, preferably the ultrasonic frequency of the ultrasonic oscillation device is 28KHz, and each group of ultrasonic oscillation devices includes 100 vibrators, and the power of each vibrator is 100 watts.

[0141] As one of the embodiments of the present invention, an automatic dyeing liquid batching system is also provided;

[0142] As one of the embodiments of the present invention, the first roller assembly is the same as the second roller assembly or the first roller assembly is a traditional roller assembly.

[0143] The second pressure device 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.

[0144] As one of the embodiments of the present invention, the outer circumference of the first and / or second roller body is covered with an elastic layer, which is one or more of rubber, silicone, nylon, etc., or a fiber layer composed of paper, fabric, etc.

[0145] As one of the embodiments of the present invention, the first roller body is an anilox roller with a concave or convex dot-shaped texture pattern on the surface.

[0146] As one of the embodiments of the present invention, 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 second pressure device and the fourth pressure device, the outer cylindrical surface of the roller body is pre-processed by a machine tool 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 is slightly reduced from the middle to the two ends (for example, the middle height is 0.1mm).

[0148] Furthermore, a trough lifting airbag is connected to the bottom of the trough lifting cylinder. The stroke of the trough lifting cylinder plus the stroke of the trough lifting airbag is the total stroke of the trough. The setting of the trough lifting cylinder can make the trough 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 and between the last impregnation wheel and the second roller more stable.

[0149] Furthermore, the end shaft of the bottom impregnation wheel passes through the material trough, the end shaft of the bottom impregnation wheel is connected to a mechanical seal bearing, and is rotatably connected to the material trough through the mechanical seal bearing, and one of the end shafts of the bottom impregnation wheel is connected to a power device.

[0150] Alternatively, the impregnation wheel at the top is rotatably connected to the frame, and at least one of its end shafts extends out of the trough, and transmits power to the second roller through gears. The trough is connected to a trough lifting device, which is connected to the frame and includes a trough lifting limit device, a lifting guide device, a lifting power device, etc.

[0151] Furthermore, it also includes an impregnated wheel lifting device, which includes a slide groove, which is arranged on the inner wall of the two ends of the material trough, and the end shaft of the impregnated wheel is slidably arranged in the slide groove. Each of the impregnated wheels 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.

[0152] Furthermore, the end shaft of the impregnation wheel is provided with a rolling bearing, and the rolling bearing is arranged to roll or slide in the slide groove.

[0153] The shaft end of the impregnation wheel is rotatably connected to the impregnation wheel lifting device, which drives each impregnation wheel to rise in sequence and stops when it rises to the working position. When the material trough descends, the impregnation wheel lifting device drives each impregnation wheel to descend in sequence.

[0154] As one of the embodiments of the present invention, the end shafts of two adjacent impregnation wheels are movably connected via a hook or a ring, and a certain distance is maintained between the adjacent impregnation wheels via the hook or the ring.

[0155] As one of the embodiments of the present invention, a plurality of pins or screws are arranged at intervals above and below the slide. Except for the lowest impregnation wheel, the remaining impregnation wheels can be fixed on the slide by the pins or screws, and maintain a preset distance between the adjacent impregnation wheels. When the pins or screws are separated from the slide, the impregnation wheels press each other under the action of their own gravity.

[0156] As one of the embodiments of the present invention, in order to facilitate the cleaning of the material trough and the pulling of the material, the material trough is also provided with a flipping device. The material trough is rotatably arranged on the inner side of the frame around the axis of the lowest impregnation wheel, and the material trough can be tilted and flipped by external power.

[0157] As one of the embodiments of the present invention, in order to facilitate the pulling of materials or the selection of whether to dip and dye, the material trough is provided with a material trough lifting device. Under the action of a cylinder or a hydraulic cylinder or manual force, the material trough is lifted and lowered through the guidance of a lever or a slide rail, and the material trough is separated from the working position.

[0158] As one of the embodiments of the present invention, in order to facilitate the cleaning of the material trough and material replacement, the material trough is a movable material trough, and four casters are arranged at the bottom of the material trough. During production, the impregnation wheel group is lowered and immersed in the material trough. When changing materials, the impregnation wheel group is raised to move the material trough away for replacement.

[0159] As one of the embodiments of the present invention, the material tank is also provided with a cooling or heating device of a double-layer sandwich structure, and the functional solution in the material tank is maintained at a preset temperature by injecting steam or heat transfer oil or hot water or cold water into the sandwich.

[0160] As an example, ( Figure 5 / 7) A second group of rollers is also arranged behind the heavy-loaded uniform pressing device of the present invention. The first group of heavy-loaded uniform pressing devices of the present invention applies active dye solution to the fabric to obtain a lower liquid carrying rate, preferably 50-60%. The liquid carrying rate of the fabric is not saturated, so after entering the second group of rollers, the fabric can still carry more solution, preferably 100-120% (the saturated liquid carrying rate of pure cotton fabric is about 120%). The solution in the second group of rollers is a color fixing alkali agent, preferably the alkali agent is arranged above the two rollers of the second group of rollers. The two rollers of the second group of rollers A liquid storage area is formed above the rollers, and the cloth runs downward from above between the two rollers of the second group of rollers. Although a part of the active dye solution applied to the cloth by the heavy-load uniform pressing device of the present invention in the previous group will fall off and dissolve into the liquid storage area, 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 that of the traditional roller. During high-speed operation, the solution exchange rate is fast and the solution exchange equilibrium can be quickly reached. Therefore, the amount of active dye shedding and hydrolysis in the liquid storage area is limited, which will not have a significant impact on product quality.

[0161] A specific application example of the present invention during washing and dyeing is shown in Figure 3 , 4 The heavy-load uniform rolling device at least includes a frame, one first rolling roller assembly, and three second rolling roller assemblies.

[0162] The first roller is rotatably connected to the frame through first bearing seats at both ends thereof, and three second rollers are arranged in the circumferential direction of the first roller. The three second rollers are respectively pressed and rolled with the outer cylindrical surface of the first roller through the corresponding third pressure devices and the fourth pressure devices. The substrate passes between the first roller and each of the second rollers in turn, and is continuously pressed and rolled three times by the first roller and each of the second rollers.

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

[0164] A material trough is provided below the second roller and the first roller, three impregnation wheels are provided in the material trough, and the ultrasonic oscillation device is provided on the side wall of the material trough;

[0165] End sealing components and feeding devices are provided at both ends between the first roller and the second roller, and sealing components are provided at both ends of the second roller and the first roller;

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

[0167] The outer circumferences of the first and second roller bodies are coated with a rubber layer.

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

[0169] The cloth enters the material trough, passes through the impregnation wheels in turn, and the impregnation wheels are pressed together in turn. The last impregnation wheel is pressed together with the first roller. The cloth enters the first roller from the last impregnation wheel, runs around and follows the first roller, enters between the first second roller and the first roller, is pressed for the first time, then separates from the first roller, and passes over the first exhaust roller, then enters between the second second roller and the first roller, is pressed again, the cloth separates from the first roller after being pressed, and passes over the second exhaust roller, then enters between the third second roller and the first roller, is pressed for the third time, and then is output to the next process for drying, color fixing, shaping and other treatments.

[0170] The material trough contains a reactive dye solution, and the cloth carries excess dye solution after being squeezed by each impregnation wheel. After being pressed between the first second roller and the first roller, a quantitative reactive dye solution is obtained. 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 carrying rate, preferably a liquid carrying rate of 50%.

[0171] A color-fixing alkali agent is placed above the second roller and the first roller. When the cloth passes between the second roller and the first roller, it is pressed for the second time to obtain a quantitative mixed solution of active dye and color-fixing alkali agent. At this stage, the pressure between the second roller and the first roller is relatively small, and the cloth can obtain a higher liquid-carrying rate, preferably a liquid-carrying rate of 100%.

[0172] As the machine runs, the cloth enters between the third second roller and the first roller and is pressed for the third time. The third pressing serves to further homogenize the solution carried on the surface of the cloth. Preferably, the pressure is not greater than the pressure during the second pressing to avoid squeezing out the mixed liquid carried by the cloth.

[0173] After the third pressing, the fabric is output to the next process for drying, color fixing, shaping and other treatments.

[0174] During the weaving process, the fabric must be treated with sizing or oil before it can be woven normally. During this process, the fabric will carry sizing or lubricating oil. The presence of sizing or lubricating oil is not conducive to continuous dyeing and must be removed before dyeing.

[0175] 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.
