Description

Technical Field

[0002] In the traditional textile printing and dyeing process, the fabric needs to be coated with dye or various chemical solutions, and then the fabric with dye is heated, dried, shaped, colored and fixed. There are many traditional coating methods, such as uniform rolling, heavy-load rolling, etc., but these methods are to soak the fabric in the solution and then squeeze out the excess solution by rolling. In this way, the amount of liquid on the fabric after rolling is relatively high, which can easily cause the migration of dyes in the subsequent high-temperature drying process, affecting product quality. In addition, the energy consumption in the drying process is too high, which is not conducive to energy saving and environmental protection.

DETAILED DESCRIPTION

[0037] The embodiment of the invention discloses a printing and rolling coating device and a continuous dyeing machine, which are used to solve the technical problem that the existing cloth has a high amount of liquid after pressing.

[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] See also Figures 1 to 3 , a printing and rolling coating device provided in this embodiment includes:

[0041] Frame 1, printing and rolling assembly, receiving trough 7, first pressure device 5 and second pressure device 6;

[0042] The printing and rolling assembly includes a first printing and rolling die set 15, which includes at least a first liquid-carrying roller 2, a first hydraulic pressure limiting roller 3, and a first rolling roller 4. The first liquid-carrying roller 2 is rotatably arranged on the frame 1, and a recess is arranged on the outer surface of the first liquid-carrying roller 2. The first liquid-carrying roller 2 is a liquid-carrying roller with a steel or ceramic surface, and the first hydraulic pressure limiting roller 3 and the first rolling roller 4 are both elastic rubber-coated rollers;

[0043] The material receiving trough 7 is arranged on the inner side of the frame 1, and the material receiving trough 7 is located below the printing and rolling assembly. The first hydraulic limit roller 3 is rotatably arranged on the frame 1, and the first hydraulic limit roller 3 is connected to the first pressure device 5. The first pressure device 5 can drive the first hydraulic limit roller 3 and the first liquid-carrying roller 2 to be pressed against each other. When the first pressure device 5 drives the first hydraulic limit roller 3 and the first liquid-carrying roller 2 to be pressed against each other, a liquid storage area for the raw material solution is formed between the first hydraulic limit roller 3 and the first liquid-carrying roller 2. The running directions of the first hydraulic limit roller 3 and the first liquid-carrying roller 2 are opposite. The first rolling roller 4 is rotatably arranged on the frame 1, and the first rolling roller 4 is connected to the second pressure device 6. The second pressure device 6 can drive the first rolling roller 4 and the first liquid-carrying roller 2 to be pressed against each other.

[0044] In this embodiment, under the working state, a liquid storage area for the raw material solution is formed between the first hydraulic pressure limiting roller 3 and the first liquid carrying roller 2. The running direction of the first hydraulic pressure limiting roller 3 is opposite to that of the first liquid carrying roller 2. The first hydraulic pressure limiting roller 3 presses the first liquid carrying roller 2 so that the solution on the surface of the first liquid carrying roller 2 is squeezed out and stays in the liquid storage area. Only a certain amount of solution is retained in the recessed part of the first liquid carrying roller 2 and rotates with the first liquid carrying roller 2. The first roller 4 can be driven by the second pressure device 6 to press the liquid carrying rollers against each other. The cloth to be processed passes between the first roller 4 and the first liquid carrying roller 2, and the certain amount of solution retained in the recessed part of the liquid carrying roller will be pressed into the organizational structure of the cloth fiber. Through the above design, the amount of liquid entering the cloth can be reduced to a minimum as needed. With the pressing of the first roller 4, the dye solution can be effectively pressed into the internal structure of the substrate, which well solves the technical problem that the existing cloth has a high amount of liquid after pressing, thereby ensuring product quality.

[0045] Furthermore, it also includes a batching device;

[0046] The batching device includes at least one raw material barrel 17, at least one stirring barrel 23, at least one material receiving barrel 20 and at least one electronic weighing device 19, the bottom of the electronic weighing device 19 is fixed on the frame 1, the material receiving barrel 20 is placed on the electronic weighing device 19, a first pipeline 18 and a first pump are connected between the raw material barrel 17 and the material receiving barrel 20, a fourth valve and a fourth pipeline 21 are connected between the material receiving barrel 20 and the stirring barrel 23, a second pipeline 25 and a second valve leading to the liquid storage area are connected to the bottom of the stirring barrel 23, and a third pipeline 22 and a third pump are connected between the material receiving trough 7 and the stirring barrel 23.

[0047] It should be noted that, in order to prevent the dye solution from settling at the bottom of the receiving trough 7, the bottom of the receiving trough 7 is designed to be inclined from left to right, with the left side higher and the right side lower, and a discharge hole is provided at the lowest point. The third pipe 22 and the valve (or pump) are connected to the discharge hole and then pass into the stirring barrel 23.

[0048] Furthermore, in order to improve the accuracy of measurement, a material receiving bucket 20 and an electronic weighing device 19 are also arranged between the first pipeline 18 and the mixing barrel 23. Preferably, the bottom of the material receiving bucket 20 is a funnel-shaped conical design, and the bottom of the cone is provided with a fourth valve and a fourth pipeline 21. The bottom of the electronic weighing device 19 is fixed on the frame 1, and the material receiving bucket 20 is placed on the electronic weighing device 19. The outlet end of the first pipeline 18 leads to the material receiving bucket 20, and the outlet end of the fourth pipeline 21 leads to the mixing barrel 23.

[0049] The raw material barrel 17 is one or more raw material barrels 17 , and each raw material barrel 17 is correspondingly provided with at least one first pump or valve and a first pipe 18 , the first valve is connected to the bottom of the cone, one end of the first pipe 18 is connected to the first valve, and the other end leads to the material receiving barrel 20 .

[0050] The valve is one or more of an electric valve, a pneumatic valve, a manual valve, a proportional control valve, etc., and the pump is one or more of a gear pump, a vane pump, a diaphragm pump, a metering pump, etc.

[0051] In this embodiment, the number of the raw material barrels 17 can be four, each containing a different dye solution, such as red, yellow and blue primary color dye solutions, and an auxiliary solution. These solutions are respectively input into the stirring barrel 23 through their respective first pipeline 18 valves or / and pumps, and after stirring, they are output from the second pipeline 25 to the first liquid storage area between the first liquid-carrying roller 2 and the first hydraulic pressure limiting roller 3. When the first liquid-carrying roller 2 rotates, the excess dye solution is removed by the first hydraulic pressure limiting roller 3, and a certain amount of dye solution remains on the surface of the first liquid-carrying roller 2. When the cloth passes between the first liquid-carrying roller 2 and the first roller 4, the certain amount of dye solution on the first liquid-carrying roller 2 is transferred to the surface (front) of the cloth.

[0052] Before production, the solution is prepared according to the production instructions. Before preparing the solution, the second valve (or pump) and the fourth valve (or pump) are closed, and the first valve (or pump) is opened. The first valve (or pump) injects the raw material solution into the receiving barrel 20. When the electronic weighing device 19 displays that the weight reaches the predetermined requirement, the first valve (or pump) is closed, and the fourth valve (or pump) is opened. The raw material solution is injected into the mixing barrel 23 through the fourth pipe 21, and the mixer is started to stir until it is evenly stirred.

[0053] The second valve (or pump) is opened, and the uniformly stirred raw material solution is injected into the liquid storage area through the second pipeline 25 .

[0054] As the liquid-carrying roller and the device hydraulic pressure limiting roller rotate, the solution on the surface of the liquid-carrying roller is squeezed out and remains in the liquid storage area. Only the concave points in the working area of ​​the liquid-carrying roller retain a certain amount of solution. As the liquid-carrying roller rotates, the cloth to be processed passes between the roller and the device liquid-carrying roller, and the certain amount of solution retained in the concave points in the working area of ​​the liquid-carrying roller is pressed into the organizational structure of the cloth fiber.

[0055] When the printing and coating device 27 is provided with two printing and coating dies (the second printing and coating die set 16 is described in detail below), the printing and coating operation can be continuously performed on the front and back sides of the fabric. When the first liquid-carrying roller 2 rotates, the excess dye liquid is pressed back to the liquid storage area by the first hydraulic pressure limiting roller 3, and only a certain amount of solution in the concave part remains on the surface of the first liquid-carrying roller 2. When the fabric passes between the first liquid-carrying roller 2 and the first roller 4, the certain amount of dye liquid on the first liquid-carrying roller 2 is transferred to the surface (front) of the fabric; as the equipment is running, the fabric is transported between the second liquid-carrying roller 10 and the second roller 12. The same as the previous principle, the certain amount of dye liquid on the second liquid-carrying roller 10 is transferred to the back (reverse) side of the fabric, and the solution is uniformly infiltrated into the interior of the fabric after pressing. The excess dye liquid in the liquid storage area flows back (or overflows) to the stirring barrel 23 through the side material receiving device or / and the material receiving trough 7 through the valve of the third pipeline 22, and is stirred again, and then the above process is repeated.

[0056] Furthermore, the printing and coating device 27 and the continuous dyeing machine also include an automatic batching control system, which includes a PLC and a human-machine interface, etc. Each of the pumps, valves, and mixers is electrically connected to the automatic batching control system, and the working state of each of the pumps, valves, and mixers is controlled by pre-set batching parameters to achieve the purpose of automatic batching.

[0057] Furthermore, it also includes an ultrasonic oscillation device 24, which includes an ultrasonic generator, an amplitude transformer, a transducer and a vibrator;

[0058] The vibrator is arranged on the side wall of the raw material barrel 17 and / or the side wall of the mixing barrel 23, the amplitude transformer is connected to the ultrasonic generator, the amplitude transformer is connected to the transducer, the transducer is connected to the vibrator, the ultrasonic frequency of the ultrasonic oscillation device is between 20KHz-80KHz, and the input power of each group of ultrasonic vibration devices is between 0.2kW and 10kW.

[0059] It should be noted that, in order to further disperse the raw material solution evenly, the vibrator is arranged on the side wall of the raw material barrel 17 and / or the stirring barrel 23 or connected to the pipeline, and the amplitude transformer is connected to the ultrasonic generator. The amplitude transformer amplifies or reduces the amplitude of the ultrasonic generator and transmits it to the transducer. The piezoelectric ceramic in the transducer converts the electrical energy into mechanical energy of vibration, and then the vibrator transmits the vibration to the dye solution.

[0060] Furthermore, a stirring device is also provided in the raw material barrel 17. The stirring device is a fan-shaped or spiral stirring device. The stirring device is driven by a power device provided outside the barrel to keep the dye liquid in a uniformly dispersed state at all times. The power device is a pneumatic motor, a hydraulic motor or a general motor drive.

[0061] Furthermore, it also includes a third pressure device 13 and a fourth pressure device 14, and the printing and rolling assembly also includes a second printing and rolling die set 16 having the same structure and principle as the first printing and rolling die set 15, and the first printing and rolling die set 15 and the second printing and rolling die set 16 are arranged on the frame 1 in a horizontal direction (process flow direction);

[0062] The second printing and rolling die set 16 at least includes a second liquid-carrying roller 10, a second hydraulic pressure-limiting roller 11, and a second roller 12 rotatably arranged on the frame 1, the second hydraulic pressure-limiting roller 11 is connected to the third pressure device 13, the third pressure device 13 can drive the second hydraulic pressure-limiting roller 11 to press and roll with the second liquid-carrying roller 10, the second roller 12 is connected to the fourth pressure device 14, the fourth pressure device 14 can drive the second roller 12 to press and roll with the second liquid-carrying roller 10;

[0063] The first liquid-carrying roller 2 and the second liquid-carrying roller 10 rotate in opposite directions.

[0064] It should be noted that, preferably, the first printing and rolling die set 15 and the second printing and rolling die set 16 are arranged front and back in the horizontal direction (process flow direction); when the first liquid-carrying roller 2 rotates, the excess dye liquid is squeezed out by the hydraulic pressure limiting roller, and a certain amount of dye liquid remains in the recessed part on the surface of the first liquid-carrying roller 2. When the cloth passes between the first liquid-carrying roller 2 and the first rolling roller 4, the certain amount of dye liquid on the first liquid-carrying roller 2 is transferred to the surface (front) of the cloth; as the equipment runs, the cloth is conveyed between the second liquid-carrying roller 10 and the second rolling roller 12. Similar to the above principle, the certain amount of dye liquid on the second liquid-carrying roller 10 is transferred to the back (reverse) of the cloth. After pressing and rolling, the solution evenly penetrates into the interior of the cloth, and in the subsequent high-temperature drying process, the dye will It further diffuses into the interior of the fabric, so that the amount of dye on the surface and inside of the fabric is consistent, and the excess dye in the liquid storage area flows from the side material receiving device to the material receiving trough 7. It should be noted that the running directions of the first liquid-carrying roller 2 and the second liquid-carrying roller 10 are opposite. Preferably, the first liquid-carrying roller 2 rotates counterclockwise, while the second liquid-carrying roller 10 rotates clockwise. It is further preferred that a gear transmission is used between the first liquid-carrying roller 2 and the second liquid-carrying roller 10. At the same time, when pulling the fabric, it should be noted that if the front side of the grey cloth contacts the first liquid-carrying roller 2 when passing through the first printing and rolling die set 15, then the back side of the grey cloth contacts the second liquid-carrying roller 10 when passing through the second printing and rolling die set 16. Only in this way can a quantitative amount of dye be obtained on both sides, so as to achieve the effect of evenly applying dye on the front and back sides.

[0065] In addition, the first liquid-carrying roller 2 and the second liquid-carrying roller 10 are arranged front and back in the process flow direction, the first limiting hydraulic roller 3 and the second limiting hydraulic roller 11 are respectively arranged to abut against the first liquid-carrying roller 2 and the second liquid-carrying roller 10 with an adjustable gap, the first rolling roller 4 and the second rolling roller 12 are respectively arranged to be adjustably pressed with the first liquid-carrying roller 2 and the second liquid-carrying roller 10, the first rolling roller 4 is arranged below or to the side of the first liquid-carrying roller 2, and the second rolling roller 12 is arranged below, above or to the side of the second liquid-carrying roller 10.

[0066] Further, the first printing and rolling die set 15 and the second printing and rolling die set 16 further include a first left baffle, a first right baffle, a second left baffle, and a second right baffle, respectively; the first left baffle and the first right baffle are respectively located at the two ends of the first liquid-carrying roller 2 and the first hydraulic limiting roller 3, and are respectively arranged in cooperation with the end of the first liquid-carrying roller 2 and the end of the first hydraulic limiting roller 3, and the first left baffle and the first right baffle form a liquid storage area with the first liquid-carrying roller 2 and the first hydraulic limiting roller 3, respectively; similarly, the second left baffle and the second right baffle are respectively located at the two ends of the second liquid-carrying roller 10 and the second hydraulic limiting roller 11, and are respectively arranged in cooperation with the end of the second liquid-carrying roller 10 and the end of the second hydraulic limiting roller 11, and the second left baffle and the second right baffle form a liquid storage area with the second liquid-carrying roller 10 and the second hydraulic limiting roller 11, respectively;

[0067] The baffle mentioned above is arranged in an arc shape in coordination with the outer surfaces of the corresponding hydraulic pressure limiting roller and liquid carrying roller. A through hole is arranged on the side of the baffle, and the through hole is connected to the second pipeline 25 .

[0068] Furthermore, an overflow hole is provided on the side of the baffle mentioned above, and the excess solution is stored in the liquid storage area. When the liquid level is higher than the overflow hole or the overflow inlet, the solution flows from the overflow hole to the receiving trough 7.

[0069] It should be noted that the gram weight of the fabric referred to in this article is the weight of the fabric per square meter, and the unit is g / m2. The amount of liquid carried by the first liquid-carrying roller 2 is the weight of the solution in the recessed portion of the first liquid-carrying roller 2 after the first liquid-carrying roller 2 is pressed by the first hydraulic pressure limiting roller 3, and the unit of the amount of liquid carried is g / m2. The amount of liquid carried by the fabric is the weight of the solution carried by the fabric after printing and rolling coating. The liquid carrying rate is the percentage of the weight of the solution carried by the fabric after the printing and rolling coating device 27 to the weight of the fabric itself. The first liquid-carrying roller 2 can also be called an anilox roller. The amount of liquid carried by the grey fabric finally depends mainly on the size and density of the recessed portion on the surface of the first liquid-carrying roller 2. According to the usual practice of the anilox roller, the preferred recessed portion (dot) is 80 mesh-120 mesh, and the mesh is 100 mesh. The number is inversely proportional to the liquid carrying amount. The larger the mesh number, the lower the liquid carrying amount. In the actual production process, it is necessary to select the size of the mesh number and the depth and shape of the concave points according to the actual situation, such as hexagonal, circular and other shapes. The final liquid carrying amount of the cloth is controlled by selecting the mesh number and shape of the first liquid-carrying roller 2. The theoretical liquid carrying amount of the same first liquid-carrying roller 2 is certain. Theoretically, the liquid carrying amount of cloths of different gram weights after being pressed by the same first liquid-carrying roller 2 and the first rolling roller 4 is also certain. Therefore, the liquid carrying rate of cloths of different gram weights after being coated by the same set of printing and rolling dies will be different. In actual production, different first liquid-carrying rollers 2 should be selected according to different cloths. The actual liquid carrying rate of the cloth is preferably 20-50%, and more preferably 35%.

[0070] The above content is only described by taking the first printing and rolling die set 15 as an example, which is also applicable to the description of the second printing and rolling die set 16 .

[0071] Furthermore, the first pressure device 5 and the second pressure device 6 also include a first stroke limit device, through which the gap distance between the first hydraulic limiting roller 3 and the first rolling roller 4 and the first liquid-carrying roller 2 is controlled. Similarly, the third pressure device 13 and the fourth pressure device 14 also include a second stroke limit device, through which the gap distance between the second hydraulic limiting roller 11 and the second rolling roller 12 and the second liquid-carrying roller 10 is controlled.

[0072] It should be noted that the first pressure device 5, the second pressure device 6, the third pressure device 13, and the fourth pressure device 14 all include an advance and retreat power device and its connecting parts, and the advance and retreat power device is a cylinder, an oil cylinder, a motor or a screw, etc., preferably a cylinder or an airbag.

[0073] Furthermore, it also includes an impurity removal device and an adjustment device, wherein the impurity removal device is a scraper 9 or a brush wheel 8, and the scraper 9 or the brush wheel 8 is installed on the outer surface of the first hydraulic pressure limiting roller 3 and / or the first liquid-carrying roller 2 and / or the first roller 4;

[0074] The blade of the scraper 9 or the outer edge of the brush wheel 8 abuts against the outer surface of the first liquid-carrying roller 2 or / and the first hydraulic pressure limiting roller 3 and / or the first rolling roller 4;

[0075] The scraper 9 at least includes a blade shaft, a blade seat and a blade, wherein the blade is fixed on the blade seat, both ends of the blade seat are connected to the blade shaft, the blade shaft is connected to an adjustment device, and the adjustment device is fixed on both sides of the frame 1;

[0076] The brush wheel 8 at least includes a shaft head, a shaft core connected to the shaft head, and a brush arranged on the outer surface of the shaft core, and the shaft head is connected to the adjusting device.

[0077] It should be noted that in the prior art, a scraper is used to scrape off the excess solution on the surface of the liquid-carrying roller and then a roller is used to press the surface of the cloth. This method easily causes the cloth fiber impurities carried by the cloth to adhere to the surface of the anilox roller. Since the scraper does not rotate, these impurities will be stuck between the scraper and the liquid-carrying roller, and then form strip marks on the surface of the liquid-carrying roller, affecting the quality of the product and being unfavorable for continuous production. In order to solve the above-mentioned problems, the above-mentioned scheme is designed. Through the above-mentioned design, due to the mutual pressing and relative rotation between the first hydraulic pressure limiting roller 3 and the first liquid-carrying roller 2, the impurities carried by the cloth will be taken away by the cloth as the first hydraulic pressure limiting roller 3 and the first liquid-carrying roller 2 operate, and will not be stuck between the first hydraulic pressure limiting roller 3 and the first liquid-carrying roller 2.

[0078] The first liquid-carrying roller 2 and the second liquid-carrying roller 10 mentioned in this embodiment are both liquid-carrying rollers with a double-layer structure, the outer layer of the double-layer liquid-carrying roller is a thick-walled steel pipe, and the inner layer is a thick-walled steel pipe or round steel. The diameter of the middle part of the inner layer is larger than the diameter of the two end parts, and the outer wall of the middle part of the inner layer is connected to the inner wall of the middle part of the outer layer. The two end parts of the outer layer and the inner layer are not directly connected, but are connected by abutting through a retaining ring (or baffle) arranged at the end of the outer layer, or the gap between the inner layer and the outer layer is closed by a sealing ring. The inner layer is connected to the axis, and the axis is not directly connected to the outer layer, but is connected by abutting through a retaining ring (or baffle) arranged at the end of the outer layer. The surface of the outer layer is a steel or ceramic surface, and a recessed portion is provided in its working area. The recessed portion can select a recessed point or line, and the recessed portion forms a pre-designed pattern on the surface of the outer layer;

[0079] Furthermore, the first roller 4 and the second roller 12 in this embodiment are both rollers with adjustable middle height, which are commonly referred to as uniform rollers, and a plurality of chambers are provided in the inner cavity thereof. Hydraulic oil (or air pressure) is introduced into the chambers through an external hydraulic device, and the outer diameter of the roller is adjusted by adjusting the pressure provided by the hydraulic oil as required. Alternatively, the inner cavities of the first roller 4 and the second roller 12 in this embodiment are provided with mutually matching conical sliders, and the relative positions of the conical sliders are adjusted by an external screw rod to adjust the outer diameters of the first roller 4 and the second roller 12.

[0080] Furthermore, in order to make the cloth enter the printing-rolling coating device smoothly, Figure 2 For example, an ironing device is also provided in front of the first liquid-carrying roller 2, and the ironing device includes one or more ironing wheels and a fixing device thereof, a power device, etc. The one or more ironing wheels are arranged in sequence to perform ironing and shaping operations on the cloth before entering the printing-rolling coating device. The preheating wheel is electrically heated, or heated by heat transfer oil or steam, preferably heated by heat transfer oil. The high-temperature heat transfer oil is introduced into the preheating wheel through a rotary joint, so that the preheating wheel is heated by the heat transfer oil, thereby heating the cloth passing through the ironing wheel.

[0081] Embodiment 2

[0082] See also Figures 1 to 7 After the cloth is coated with the raw material solution on one side or both sides by the printing and rolling coating device 27, it needs to be heated, dried and shaped. In this process, various physical and chemical reactions will occur between the various components in the solution and the cloth fibers under certain temperature conditions to achieve the processing purpose. This requires a continuous dyeing machine with the above-mentioned printing and rolling coating device 27 as the core component.

[0083] This embodiment provides a continuous dyeing machine, which includes a cloth sending device 26, a heating and drying setting device 28, a finished product collecting device 29 and at least one printing and rolling coating device 27 as described in the first embodiment;

[0084] The cloth sending device 26, the printing and coating device 27, the heating, drying and shaping device 28, and the finished product collecting device 29 are arranged in sequence.

[0085] Furthermore, the number of the printing and coating devices 27 is two, and the two printing and coating devices 27 are arranged in sequence.

[0086] It should be noted that, by providing two printing and rolling coating devices 27, the cloth can be coated with different components of raw material solutions on one side or both sides. For example, in the dyeing process of reactive dyes, the reactive dyes and alkali agents need to be coated on the cloth together. However, the reactive dyes and alkali agents react easily at room temperature. Therefore, in the dyeing process of reactive dyes, it is necessary to avoid the reaction between the dyes and the alkali agents before the dyes come into contact with the cloth. Since conventional devices such as a roller have a high amount of liquid during coating and cannot perform two consecutive roller coatings, active dyes and alkali agents are usually added to a material tank and then simultaneously rolled onto the fabric. This will cause the remaining active dyes and alkali agents in the material tank to react in the material tank, reducing the utilization rate of the dyes and affecting product quality. To solve this problem, the above-mentioned design is used to successively coat the fabric with dyes and alkali agents and other additives using two consecutive printing and rolling coating devices 27, so that the reaction between the dye and the alkali agent is performed only after the fabric coating is completed, effectively avoiding the hydrolysis reaction of the dye when encountering the alkali agent before contacting the fabric. After two consecutive printing and rolling coatings of the active dye and the alkali agent, the dyes and alkali agents are heated and shaped by the heating, drying and shaping device 28, and are collected as finished products after cooling.

[0087] It should be further explained that the two continuously arranged printing and rolling coating devices 27 can be two independent printing and rolling coating devices 27, or two printing and rolling coating devices 27 continuously arranged on the same frame 1. As far as reactive dyeing is concerned, it is preferred that the two continuously arranged printing and rolling coating devices 27 are two independent printing and rolling coating devices 27, and the two printing and rolling coating devices 27 are arranged before and after the process flow. It is further preferred that a ventilation device (or free diffusion device) is also provided between the two printing and rolling coating devices 27 to allow the reactive dye to freely diffuse into the internal structure of the fabric fiber after the printing and rolling coating is completed, and then the printing and rolling coating of the alkali agent is performed.

[0088] Of course, according to the process requirements, the alkali agent can be printed and applied first, and then the reactive dye can be printed and applied. After applying the alkali agent, the alkali solution can be dried by a heating device (oven, heating wheel, etc.), and then the reactive dye can be applied, and then the heating, drying, shaping and other treatment processes can be carried out.

[0089] The ventilation device includes a frame 1 and guide wheels arranged on the frame 1. Preferably, the guide wheels are divided into upper and lower layers and are staggered. The cloth after printing and rolling the active dye passes through each of the guide wheels in a serpentine shape in turn, which can increase the free diffusion time of the dye in a limited space.

[0090] As far as dyeing with disperse dyes is concerned, it is preferred that the two continuously arranged printing and rolling coating devices 27 are two printing and rolling coating devices 27 continuously arranged on the same frame 1, and the two printing and rolling coating devices 27 successively and continuously print and roll coat the dye solution on the cloth twice (or more times), which can achieve a more uniform coating effect.

[0091] For example, in the dyeing process of polyester-cotton blended fabrics, due to the different compositions of polyester and cotton fabrics, disperse dyes and reactive dyes are needed to dye the polyester and cotton components in the fabric respectively. However, when reactive dyes are used, the solution is in an alkaline state, while conventional disperse dyes require a neutral or acidic solution state. Therefore, the traditional dyeing method needs to be divided into two steps, first dyeing polyester and then dyeing cotton, which will result in complicated processes and low production capacity. To solve this problem, the present embodiment adopts disperse dyes and reactive dyes to perform dyeing processing independently but continuously. The continuous dyeing machine at least includes a cloth sending device 26, a first printing and rolling coating device 27, a first heating, drying and setting device 28, a second heating, drying and setting device 28, a second printing and rolling coating device 27, a third printing and rolling coating device 27, a third heating, drying and setting device 28 and a finished product collecting device 29 in sequence. The first printing and rolling coating device 27, the second printing and rolling coating device 27, and the third printing and rolling coating device 27 print and roll the disperse dye solution, the reactive dye solution and the alkali solution respectively. After the cloth passes through the second heating, drying and setting device 28 and the third heating, drying and setting device 28, the dyeing process of the disperse dye and the reactive dye is completed respectively.

[0092] Furthermore, the heating, drying and shaping device 28 includes a stenter shaping machine or an infrared heating device and a heating wheel group dryer or a steaming box arranged in front and behind. The working temperature of the stenter shaping machine or the infrared heating device is 60-150°C, and the working temperature of the heating wheel group dryer (or steaming box) is 120-220°C.

[0093] It should be noted that the stenter setting machine and the heating wheel group dryer are both common equipment in the textile industry. Since the stenter setting machine runs by pulling the two sides of the cloth through the needle plates (or cloth clamps) set on both sides, the other parts of the cloth will not contact the equipment, so the drying method using the stenter setting machine is also called contactless drying. At the same time, since the stenter setting machine can be set with an overfeed function to meet the gram weight requirements of the finished product, and the cloth can be stretched to a wide width as needed through the needle plates, it can play a role in changing the width and gram weight (weight of cloth per square meter) of the cloth as needed.

[0094] Since the cloth carries a large amount of raw material solution in the early stage of heating and drying, the higher the temperature, the easier it is to cause the migration of these raw material solutions. At the same time, if the cloth with a large amount of solution is contact dried using a heating wheel, the migration phenomenon will be further aggravated, thereby seriously affecting the product quality.

[0095] At the same time, a lot of waste gas will be generated during the production process, especially during the continuous dyeing process of disperse dyes, disperse dyes will sublimate into dye particles under high temperature conditions. These dye particles will adhere to the inside of the equipment. After long-term accumulation, they will form larger particles that fall on the cloth surface and pollute the product. The stenter setting machine is difficult to clean after being contaminated due to its complex internal structure, while the heating wheel set dryer has only smooth heating wheels inside the equipment, which is simple and easy to clean. Therefore, the best way is to use the stenter setting machine for non-contact drying to evaporate most of the water at low temperature, and at the same time, change the width and weight of the fabric as needed through the stenter setting machine, and use the heating wheel set dryer for high temperature heating at high temperature to make the fabric and raw materials reach the temperature required for physical and chemical reactions. Of course, for products that are not prone to migration and are not prone to generating a large amount of waste gas, any heating and drying method can be selected.

[0096] Furthermore, the number of the heating, drying and shaping devices 28 is two, and the printing and coating device 27 and the heating, drying and shaping device 28 are arranged at intervals from each other, such as Figure 7 Show.

[0097] It should be noted that, due to the high speed of continuous dyeing, sometimes the dyeing saturation is insufficient or not bright enough. For this reason, the above-mentioned design can be used to continuously set the two printing and rolling coating devices 27 and the two heating, drying and shaping devices 28, and the cloth is continuously printed and rolled, heated and dried, and then printed and rolled again, and heated and dried to enhance the dyeing saturation.

[0098] Furthermore, it also includes a batching control system and / or a color detection control system, wherein the color detection control system includes a spectrophotometer, a data processor, a data storage device and a batching control system;

[0099] The spectrophotometer is arranged in front of the finished product collecting device 29, and the spectrophotometer, data storage device, and batching control system are all electrically connected to the data processor.

[0100] The color of the finished product is detected by a spectrophotometer and digital information is generated. The measured color is separated into three primary colors by a data processor and a data storage device and compared with the sample color. Then, the control data instruction is output and the working state of each of the first valves (or / and the first pump) is controlled by an electromechanical control system to achieve the purpose of automatic batching and automatic color control. Preferably, the color measurement and color separation instrument, data storage and calculation system, and control system adopt Datacolor color measurement and matching system.

[0101] Furthermore, a humidity detection and control device is also provided behind the printing and coating device 27. The humidity detection and control device includes a humidity measurement sensor, an intelligent adjustment controller and other devices. The humidity of the cloth coming out of the printing and coating device is detected by the humidity detection device, thereby converting the corresponding liquid volume and obtaining the corresponding standard analog voltage or current signal. The controller of the pressure device is controlled by this signal, and then the output pressure of the pressure device is controlled. If the liquid volume of the cloth coming out of the printing and coating device is less than the preset liquid volume, the pressure of the first and / or second pressure device is reduced, otherwise the pressure is increased.

[0102] It should be noted that the humidity detection device is used to detect the amount of liquid on the left, middle and right sides of the cloth coming out of the printing and coating device. If the amount of liquid on the left and / or right sides is different from the amount of liquid in the middle, the pressure of the first and / or second pressure device on the left and / or right sides is controlled respectively through the detection signal, thereby achieving the purpose of controlling the amount of liquid on the left, middle and right sides to be consistent.

[0103] Furthermore, a cooling device is provided between the heating, drying and shaping device 28 and the finished product collecting device 29 , and the cooling device is a cooling wheel set or an air cooling device, which cools the cloth before entering the finished product collecting device 29 .

[0104] Further, one or more of a tension control device, an unfolding device, an electrostatic elimination device, etc. are provided at the entrance of the printing and coating device 27 or / and the entrance of the heating, drying and shaping device 28, and the unfolding device is one or more of an arc unfolding device, an aluminum sheet unfolding device, a spiral unfolding device, etc.;

[0105] Furthermore, in order to adjust and control the operating speed, a tension detection and control device is provided at the exit of the printing and coating device 27 (or at a subsequent workstation). The tension detection and control device is a swing-arm tension controller or a pressure sensor, which controls the rotation speed of the printing and coating device 27 by detecting the tension of the cloth surface.

[0106] Since a single-sided or double-sided coating and pressing of the substrate is performed by using an anilox roller with a recessed portion, the amount of liquid entering the substrate can be minimized as needed by selecting and changing the mesh size of the anilox roller surface. In addition, by the pressing of the roller, the dye solution can be effectively pressed into the internal structure of the substrate, solving the "core-impermeable" problem of the traditional round screen printing method. In addition, the existing method for cloth dipping and padding has a good solution to the problem that the amount of liquid on the cloth after pressing is too high, causing the migration of the dye in the subsequent high-temperature drying process, ensuring product quality, and effectively solving the technical problem of excessive energy consumption in the subsequent drying process, which is beneficial to energy saving and environmental protection.

[0107] Due to the mutual pressing between the first hydraulic limit roller 3 and the first liquid-carrying roller 2, the impurities carried by the cloth will be taken away by the cloth as the first hydraulic limit roller 3 and the first liquid-carrying roller 2 run, and will not be stuck between the first hydraulic limit roller 3 and the first liquid-carrying roller 2. Furthermore, an impurity removal device is installed on the outer surfaces of the first hydraulic limit roller 3 and the first liquid-carrying roller 2 to further ensure the quality of the product.

[0108] The printing-rolling coating device based on the present invention can effectively reduce the amount of liquid coated on the substrate, and solve the problems of uneven dyeing of the cloth surface, poor dyeing rate, insufficient dyeing saturation, etc.

[0109] At the same time, the printing and rolling coating device 27 and the continuous dyeing machine described in the present invention can not only dye disperse dyes and reactive dyes, but also be applied to the finishing of textiles, such as coating softeners, stiffening resins, waterproofing agents, mildew inhibitors, etc., not only can the effect of uniform coating be achieved, but also due to its quantitative liquid volume function, the amount of solution can be reduced to a minimum, saving energy consumption in the drying process and improving production capacity.

[0110] As an expansion of practical application, in addition to quantitative liquid printing-rolling coating on fabrics, the present invention can also be applied to fabric printing operations. One or more groups of the printing and rolling coating device 27 described in the present invention and a continuous dyeing machine are connected and set, and a photoelectric automatic plate registration system is added. The outer cylindrical surface of the liquid-carrying roller is set with various patterns as needed, and monochrome or multi-color, single-sided or double-sided core-through printing operations can be performed, and the application prospects are broad.

[0111] The above is a detailed introduction to a printing and coating device and a continuous dyeing machine provided by the present invention. For a person skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
