DETAILED DESCRIPTION

[0041] The first scraper assembly 7 at least includes a first blade holder 702, a first blade 701 and a first advance and retreat regulating device, the first advance and retreat regulating device is fixed on the frame 1, the first advance and retreat regulating device is connected to the first blade holder 702, the first blade 701 is fixed on the first blade holder 702, the blade edge of the first blade 701 is adjustably pressed on the outer circumferential surface of the first liquid-carrying roller 2, and a first liquid storage area is formed between the first scraper assembly 7 and the first liquid-carrying roller 2;

[0042] The second scraper assembly 8 at least includes a second blade holder, a second blade and a second advance and retreat regulating device, the second advance and retreat regulating device is fixed on the frame 1, the second advance and retreat regulating device is connected to the second blade holder, the second blade is fixed on the second blade holder, the blade edge of the second blade is adjustably pressed on the outer circumferential surface of the second liquid-carrying roller 3, and a second liquid storage area is formed between the second scraper assembly 8 and the second liquid-carrying roller 3;

[0043] The first advance and retreat regulating device and the second advance and retreat regulating device are fixed on the frame 1, the first advance and retreat regulating device is connected to the first knife holder 702, the second advance and retreat regulating device is connected to the second knife holder, and the working surface of the first liquid-carrying roller 2 and the working surface of the second liquid-carrying roller 3 are in contact with the front and back surfaces of the cloth respectively;

[0044] The liquid feeding device at least includes a material barrel 14 and a material receiving trough 6, and a pipeline connected between the material barrel 14 and the first scraper assembly 7 and the second scraper assembly 8. The material receiving trough 6 is arranged on the inner side of the frame 1 and is located below or at both ends of the first pressing device and the second pressing device.

[0045] It should be noted that the pre-treated (de-sizing, de-oiling, etc.) grey cloth to be dyed enters the micro-liquid feeding padder in this embodiment from the inlet guide wheel. The working surface of the first liquid-carrying roller 2 and the working surface of the second liquid-carrying roller 3 are provided with concave portions, which are similar to dots. The size of the dots is preferably 80-120 meshes. The first blade 701 of the first scraper assembly 7 and the second blade of the second scraper assembly 8 are pressed on the surface of the first liquid-carrying roller 2 and the surface of the second liquid-carrying roller 3, respectively. The dye enters the first liquid storage area and the second liquid storage area through the liquid feeding device. When the first liquid-carrying roller 2 and the second liquid-carrying roller 3 are running, the scrapers The dye liquid outside the dots on the surface of the liquid-carrying roller is scraped off, leaving only the dye liquid in the concave part. The grey cloth passes between the first liquid-carrying roller 2 and the first pressing roller 4. The grey cloth is pressed onto the surface of the first liquid-carrying roller 2 by the first pressing roller 4. The dye liquid in the concave part of the first liquid-carrying roller 2 is transferred to the surface of the grey cloth and pressed into the inside of the grey cloth due to the pressing action of the first pressing roller 4 and the first liquid-carrying roller 2. As the machine runs, the grey cloth enters between the second pressing roller 5 and the second liquid-carrying roller 3. As in the above process, the dye liquid in the concave part of the second liquid-carrying roller 3 is pressed into the inside of the grey cloth by the second pressing roller 5, completing the micro-liquid feeding impregnation process.

[0046] It should be noted that the amount of liquid finally obtained by the grey cloth mainly depends on the size and density of the concave parts (dots) on the surface of the liquid roller. According to the usual practice of the anilox roller, the preferred dot is 80-120 mesh. The mesh number is inversely proportional to the amount of liquid. The larger the mesh number, the lower the amount of liquid. In the actual production process, the size of the mesh number and the shape of the concave parts need to be selected according to the actual situation, such as diamond, circle and other shapes.

[0047] It should be further explained that the rotation directions of the first liquid-carrying roller 2 and the second liquid-carrying roller 3 are opposite. It is preferred that the first liquid-carrying roller 2 rotates counterclockwise, while the second liquid-carrying roller 3 rotates clockwise. It is further preferred that gear transmission is adopted between the first liquid-carrying roller 2 and the second liquid-carrying roller 3. At the same time, it should be noted that if the front side of the grey cloth contacts the first liquid-carrying roller 2 when the grey cloth passes through the first pressing device, the back side of the grey cloth contacts the second liquid-carrying roller 3 when the grey cloth passes through the second pressing device. In this way, a certain amount of dye can be obtained on both the front and back sides, so as to achieve the effect of evenly applying the dye on the front and back sides.

[0048] In this embodiment, since a liquid-carrying roller with a concave or convex portion is used to coat and press the substrate on both sides, the amount of liquid entering the substrate can be reduced to a minimum as needed by selecting and changing the mesh size of the screen pattern. In addition, by pressing the pressing 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 rolling has a high amount of liquid on the cloth after pressing, which causes the problem of dye migration in the subsequent high-temperature drying process, thereby 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.

[0049] Further, the first scraper assembly 7 further includes a first left baffle plate and a first right baffle plate 703, the first left baffle plate and the first right baffle plate 703 are respectively located at the two ends of the first liquid-carrying roller 2 and the first blade 701, and are respectively arranged in cooperation with the two ends of the first liquid-carrying roller 2 and the first blade 701, and the first left baffle plate and the first right baffle plate 703 form a first liquid storage area with the first liquid-carrying roller 2 and the first blade 701;

[0050] The second scraper assembly 8 includes a second left baffle and a second right baffle, and the second left baffle and the second right baffle are respectively located at the two ends of the second liquid-carrying roller 3 and the second blade, and are respectively arranged in cooperation with the two ends of the second liquid-carrying roller 3 and the second blade. The second left baffle and the second right baffle form a second liquid storage area with the second liquid-carrying roller 3 and the second blade.

[0051] Optionally, the first left baffle plate and the first right baffle plate 703 are fixed to the two ends of the first blade 701 and the first liquid roller 2 by means of a cylinder, a spring or a magnet adsorption, so as to seal or block the dye liquid from flowing out from the two ends of the first blade 701 and the first liquid roller 2; similarly, the second left baffle plate and the second right baffle plate can also be fixed to the two ends of the second blade and the second liquid roller 3 by means of a cylinder, a spring or a magnet adsorption, so as to seal or block the dye liquid from flowing out from the two ends of the second blade and the second liquid roller 3.

[0052] Furthermore, the first tool holder 702 and the second tool holder are both provided with a through hole 17 along their axial direction, and the first tool holder 702 and the second tool holder are both provided with a plurality of discharge holes 18 along their diameter direction, one end of the discharge hole 18 is connected to the through hole 17, and the other end is arranged toward the liquid storage area, and the through hole 17 is connected to the liquid feeding device.

[0053] Furthermore, a dye liquor stirring device is also provided in the material barrel 14 and / or the receiving trough 6. The dye liquor stirring device is a fan-shaped or spiral stirring device. The dye liquor stirring device is connected to a driving device, and the driving device is a pneumatic motor, a hydraulic motor or an electric motor.

[0054] Furthermore, the liquid feeding device also includes at least one raw material barrel 9, a first pipe 10 and a first pump 11 connecting the raw material barrel 9 and the receiving trough 6 or / and the barrel, a second pipe 12 and a second pump 13 connected between the barrel 14 and the pressing device, a side receiving device, a third pipe 15 and a third pump connected between the receiving trough 6 and the barrel 14;

[0055] The raw material barrel 9 can be arranged above the rolling mill, and can also be arranged on the side of the rolling mill.

[0056] Optionally, the receiving trough 6 is arranged inside the frame 1 and below the rolling device, and the bottom of the receiving trough 6 is arranged in an inclined shape from left to right in the width direction of the first liquid-carrying roller 2, and the bottom of the receiving trough 6 is higher on the left and lower on the right, which is conducive to the circulation of dye liquid and does not leave too much dye liquid at the bottom of the receiving trough 6. A discharge hole is arranged at the bottom on the right side, and one end of the third pipe 15 is connected to the discharge hole, and the other end is connected to the material barrel 14.

[0057] The bottom of the conventional receiving trough 6 is horizontally arranged in the left and right directions, which will cause too much dye liquid to remain at the bottom of the receiving trough 6, causing the dye liquid to precipitate and adhere to the bottom of the trough, which is not conducive to the continuous circulation and stirring of the dye liquid. Through the inclined trough design, the dye liquid flows smoothly and is not easy to precipitate and adhere to the bottom of the receiving trough 6.

[0058] It should be noted that the raw material barrel 9 includes at least one raw material barrel 9 for accommodating dye solution or auxiliary agent solution. These solutions enter the material barrel 14 through the respective first pipes 10 and first pumps 11 through the material receiving trough 6, and are stirred by the dye solution stirring device and then output by the second pipe 12 and the second pump 13 to the first liquid storage area between the first liquid roller 2 and the first scraper assembly 7, and can also be output to the second liquid storage area. When the first liquid-carrying roller 2 rotates, the excess dye is scraped off by the scraper, and a certain amount of dye 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 pressing roller 4, the certain amount of dye on the first liquid-carrying roller 2 is transferred to the surface (front) of the cloth; as the equipment operates, the cloth is transported between the second liquid-carrying roller 3 and the second pressing roller 5. Similar to the previous principle, the certain amount of dye on the second liquid-carrying roller 3 is transferred to the back (reverse) of the cloth. After pressing, the solution evenly penetrates into the interior of the cloth, and in the subsequent high-temperature drying process, the dye will further diffuse into the interior of the cloth, so that the surface and internal dye amounts of the cloth are consistent. The excess dye in the first liquid storage area and the second liquid storage area is refluxed (or overflowed) to the material barrel 14 through the side material receiving device or / and the material receiving trough 6 through the third pipe 15 valve, stirred again, and then the above process is repeated.

[0059] It should be further explained that the excess solution is stored in the first liquid storage area and the second liquid storage area, and when the liquid level is higher than the overflow hole or the overflow inlet, the solution flows back from the overflow hole to the material tank.

[0060] Furthermore, the liquid feeding device includes at least four raw material barrels 9, and at least four first pipes 10 and first pumps 11 connecting the raw material barrels 9 and the material barrels 14;

[0061] The micro-liquid feeding roller also includes a color detection control system, which includes a spectrophotometer, a data processor and a data storage device, and a batching control system; the spectrophotometer, the data storage device, and the batching control system are all electrically connected to the data processor.

[0062] The spectrophotometer is arranged behind the output end of the rolling mill, or above or / and below the rear of the subsequent heating and baking device, to detect the color of the product, compare the color data in the data processor with the data storage, and output an electronic signal to the ingredient control system, which controls the flow rate of each of the first pumps through the ingredient control system to achieve the purpose of controlling the color of the product.

[0063] It should be noted that the color of the finished product is detected by a spectrophotometer and digital information is formed. 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 11) 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 the Datacolor color measurement and matching system.

[0064] Furthermore, it also includes an ultrasonic oscillation device, which includes an ultrasonic generator, an amplitude transformer, a transducer and a vibrator;

[0066] It should be noted that the amplitude transformer amplifies or reduces the amplitude of the sound wave generator and transmits it to the transducer. The piezoelectric ceramics in the transducer can convert electrical energy into mechanical energy of vibration, and then the vibrator transmits the vibration to the dye solution.

[0067] Furthermore, the first liquid-carrying roller 2 and the second liquid-carrying roller 3 are arranged in sequence, the first blade 701 and the second blade are respectively arranged to abut against the first liquid-carrying roller 2 and the second liquid-carrying roller 3 with an adjustable gap, the first pressing roller 4 and the second pressing roller 5 are respectively arranged to be adjustably pressed against the first liquid-carrying roller 2 and the second liquid-carrying roller 3, the first pressing roller 4 is arranged below or to the side of the first liquid-carrying roller 2, and the second pressing roller 5 is arranged below, above or to the side of the second liquid-carrying roller 3.
