Description

Technical Field

[0001] This application relates to the field of knitted fabric dyeing technology, and in particular to a color difference correction device for polyester knitted dyed fabric. Background Technology

[0002] In the textile printing and dyeing industry, polyester knitted fabric is widely used in clothing, home textiles, and other fields due to its good elasticity and strong abrasion resistance. Printing and dyeing is an essential processing step in the production and processing of polyester knitted fabric.

[0003] In existing technologies, the dyeing of polyester knitted fabrics mainly employs traditional immersion dyeing processes. During the dyeing process, to ensure dyeing quality, workers need to inspect the dyed polyester knitted fabric for color difference. When color difference is detected, it is usually corrected by re-dyeing or applying dye to specific areas. However, traditional methods of correcting color difference by re-dyeing or applying dye to specific areas are relatively simple, labor-intensive, and time-consuming. They are also prone to causing secondary color differences, resulting in poor dyeing consistency of the polyester knitted fabric and making it difficult to meet production requirements.

[0004] Therefore, we propose a color difference correction device for polyester knitted dyed fabrics to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a color difference correction device for polyester knitted dyed fabric, which has an integrated operation process that can realize the dyeing, color difference detection and uniform dyeing correction of polyester knitted fabric. Moreover, when performing color difference correction, under the synergistic effect of the color difference correction component and the two sets of vibration cloth components, the efficiency and quality of color difference correction and elimination of polyester knitted fabric can be improved, and the dyeing consistency effect can be improved.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a color difference correction device for polyester knitted fabric, comprising a dyeing pool with an open top, wherein the dyeing pool is used to hold a dye solution for dyeing polyester knitted fabric, three guide rollers arranged in a V-shape are rotatably installed in the dyeing pool, and three guide rollers arranged in a V-shape are rotatably installed in the dyeing pool, with the guide rollers I located to the left of the guide rollers II, a U-shaped plate fixedly installed at the top of the dyeing pool between the guide rollers I and II, a high-definition camera fixedly installed at the bottom of the U-shaped plate, and a set of color difference correction components and two sets of vibrating cloth components are provided at the top of the dyeing pool, with the two sets of vibrating cloth components symmetrically distributed in the color difference correction... On the left and right sides of the positive component, the color difference correction component includes a horizontal baffle, a conveying pump, a dye liquor suction pipe, a dye liquor output pipe, a V-shaped spray plate, and multiple nozzles. The horizontal baffle is fixedly installed on the top of the dyeing tank and located on the right side of the U-shaped plate. The conveying pump is fixedly installed on the top of the horizontal baffle. The dye liquor suction pipe is fixedly installed on the suction end of the conveying pump, with the end of the dye liquor suction pipe away from the conveying pump extending into the dyeing tank. The dye liquor output pipe is fixedly installed on the discharge end of the conveying pump, with the end of the dye liquor output pipe away from the conveying pump passing through the horizontal baffle. The V-shaped spray plate is fixedly connected to the end of the dye liquor output pipe away from the conveying pump. Multiple nozzles are evenly distributed on the outer walls of both sides of the V-shaped spray plate, which is located between three guide rollers.

[0007] A further feature of this application is that the number of high-definition cameras is not less than two, and they are distributed at equal intervals.

[0008] A further provision of this application is that two inclined baffles are fixedly installed at the bottom of the horizontal baffle, and the two inclined baffles are symmetrically distributed on the left and right sides of the V-shaped spray plate.

[0009] A further configuration of this application is as follows: the vibrating cloth assembly includes a crossbeam, four telescopic vertical rods, a top plate, multiple springs, a vibrating plate, and a vibrating motor. The crossbeam is fixedly installed inside the dyeing tank. The four telescopic vertical rods slide through the crossbeam and are symmetrically distributed in pairs. The top plate is fixedly installed at the top of the four telescopic vertical rods. The multiple springs are fixedly installed at the top of the crossbeam and are evenly distributed. The tops of the multiple springs are fixedly connected to the bottom of the top plate. The vibrating plate is fixedly installed at the bottom of the four telescopic vertical rods. The vibrating motor is fixedly installed at the top center of the vibrating plate.

[0010] A further provision of this application is that: guide roller three and guide roller four are rotatably installed in the dyeing pool, with guide roller three located on the right side of the vibrating cloth assembly and guide roller four located to the lower right of guide roller three.

[0011] A further configuration of this application is that the tops of the two upper guide rollers 1, 2, and 3 are flush with each other.

[0012] A further feature of this application is that guide rollers are rotatably mounted on both the top left and top right sides of the dyeing pool via brackets.

[0016] This application utilizes the synergistic effect of two sets of vibrating cloth components. During the secondary dyeing process of polyester knitted fabric with color differences, by controlling the vibrating plate to generate high-frequency vertical vibration, the polyester knitted fabric can be continuously and slightly shaken during the secondary dyeing process. This disrupts the surface tension of the dye liquor, promotes the penetration of dye molecules into the fiber interior, and further improves the efficiency and quality of color difference correction and elimination of polyester knitted fabric, thereby enhancing dyeing consistency.

[0024] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figures 1-6 This application provides a color difference correction device for polyester knitted fabric, including a dyeing pool 1 with an open top, which holds a dye solution for dyeing polyester knitted fabric. Three guide rollers 2 arranged in a V-shape are rotatably mounted in the dyeing pool 1, and three guide rollers 3 arranged in a V-shape are also rotatably mounted in the dyeing pool 1. The guide rollers 2 are located to the left of the guide rollers 3. The height of the lowest guide roller 2 is lower than that of the lowest guide roller 3. The level of the dye solution in the dyeing pool 1 is such that the lowest guide roller 2 is submerged in the dye solution, while the lowest guide roller 3 is above the level of the dye solution. A U-shaped plate is fixedly mounted on the top of the dyeing pool 1 between the guide rollers 2 and 3. 4. A high-definition camera 5 is fixedly installed at the bottom of the U-shaped plate 4. There are no fewer than two high-definition cameras 5, which are evenly spaced. By setting up no fewer than two high-definition cameras 5, the dyed polyester knitted fabric can be comprehensively photographed, and the color image data of the polyester knitted fabric surface can be fully captured, avoiding the omission of local color difference detection. It should be noted that the high-definition camera 5 is electrically connected to an external monitor through wires (the wiring method is common knowledge in this field and is a mature technology, which will not be described in detail here). The image captured by the high-definition camera 5 can be displayed on the monitor for the staff to view, thereby judging whether there is a color difference on the surface of the polyester knitted fabric, laying a good foundation for subsequent color difference correction.

[0026] In this embodiment, a set of color difference correction components 6 and two sets of vibration cloth components 7 are provided on the top of the dyeing pool 1. The two sets of vibration cloth components 7 are symmetrically distributed on the left and right sides of the color difference correction components 6. The color difference correction components 6 include a horizontal baffle 61, a delivery pump 62, a dye liquor suction pipe 63, a dye liquor output pipe 64, a V-shaped spray plate 65, and multiple nozzles 66. The horizontal baffle 61 is fixedly installed on the top of the dyeing pool 1 and located on the right side of the U-shaped plate 4. The delivery pump 62 is fixedly installed on the top of the horizontal baffle 61. The dye liquor suction pipe 63 is fixedly installed at the suction end of the delivery pump 62, and the end of the dye liquor suction pipe 63 away from the delivery pump 62 extends into the dyeing pool 1. The dye liquor output pipe 64 is fixedly installed at the discharge end of the delivery pump 62, and the end of the dye liquor output pipe 64 away from the delivery pump 62 passes through the horizontal baffle 61. The V-shaped spray plate 65 is located away from the dye liquor output pipe 64. One end of the V-shaped spray plate 65 is fixedly connected to the conveying pump 62, and the rear side of the V-shaped spray plate 65 is fixedly connected to the rear inner wall of the dyeing tank 1, which can enhance the stability of the V-shaped spray plate 65 during use. Multiple nozzles 66 are evenly distributed on both outer walls of the V-shaped spray plate 65. The V-shaped spray plate 65 is located between three guide rollers 2 3. The conveying pump 62 is used to pump the dye solution in the dyeing tank 1, so that the dye solution enters the V-shaped spray plate 65 through the dye liquor output pipe 64, and finally sprays out from multiple nozzles 66. When a color difference is detected in a certain part of the dyed polyester knitted fabric, when the part of the polyester knitted fabric with a color difference passes between the three guide rollers 2 3, by controlling the operation of the conveying pump 62, the dye solution sprayed from multiple nozzles 66 can be sprayed onto the part of the polyester knitted fabric with a color difference, thereby performing secondary dyeing to effectively correct and eliminate the color difference.

[0027] In this embodiment, two inclined baffles 67 are fixedly installed at the bottom of the horizontal baffle 61. The two inclined baffles 67 are symmetrically distributed on the left and right sides of the V-shaped spray plate 65. With the synergistic effect of the two inclined baffles 67 and the horizontal baffle 61, the dye solution can be prevented from splashing everywhere.

[0028] In this embodiment, the vibrating cloth assembly 7 includes a crossbeam 71, four telescopic vertical rods 72, a top plate 73, multiple springs 74, a vibrating plate 75, and a vibrating motor 76. The crossbeam 71 is fixedly installed inside the dyeing tank 1. The four telescopic vertical rods 72 slide through the crossbeam 71 and are symmetrically distributed in pairs. The top plate 73 is fixedly installed at the top of the four telescopic vertical rods 72. The multiple springs 74 are fixedly installed at the top of the crossbeam 71 and are evenly spaced. The tops of the multiple springs 74 are fixedly connected to the bottom of the top plate 73. The vibrating plate 75 is fixedly installed at the bottom of the four telescopic vertical rods 72. The vibrating motor 76 is fixedly installed at the top center of the vibrating plate 75. The vibration motor 76 is used to operate... The vibration force generated during the process, under the elastic force of the spring 74 and guided by the sliding vertical rod 72 through the crossbeam 71, can control the vibrating plate 75 to generate high-frequency vibration in the vertical direction. This allows the polyester knitted fabric to continuously and slightly shake during the secondary dyeing process, disrupting the surface tension of the dye liquor and promoting the penetration of dye molecules into the fiber. It is particularly effective for dyeing the gaps in the loop structure of the polyester knitted fabric, further improving the efficiency and quality of color difference correction and elimination. Moreover, by operating two sets of symmetrically distributed vibrating cloth components 7 simultaneously, they can act synchronously on both sides of the polyester knitted fabric, avoiding the offset of the polyester knitted fabric caused by unilateral vibration, ensuring uniform vibration across the entire width, and improving dyeing consistency.

[0029] In this embodiment, guide roller 3 8 and guide roller 4 9 are rotatably installed inside the dyeing pool 1. Guide roller 3 8 is located on the right side of the fabric shaking assembly 7, and guide roller 4 9 is located to the lower right of guide roller 3 8. The tops of the two guide rollers 1 2 and the two guide rollers 2 3 are flush with the top of guide roller 3 8. The coordinated action of guide roller 3 8, guide roller 4 9 and two guide rollers 5 10, with guide rollers 5 10 rotatably installed on the top left and top right sides of the dyeing pool 1 via brackets, facilitates the smooth and stable entry and exit of polyester knitted fabric into and out of the dyeing pool 1, and ensures that the polyester knitted fabric will not come into contact with the dyeing pool 1, thus ensuring the smooth dyeing and color difference correction of the polyester knitted fabric.

[0030] In this embodiment, a discharge pipe 11 is fixedly installed on the left side wall of the dyeing pool 1, and a discharge valve 12 is fixedly installed on the discharge pipe 11 to facilitate the discharge of dye solution in the dyeing pool 1 and to facilitate the periodic or as-needed replacement of the dye solution.

[0031] In this embodiment, as Figure 6 As shown, the direction of the two arrows indicates the direction of movement of the polyester knitted fabric.

[0032] With the above structure, when the polyester knitted fabric color difference correction device provided in this application is used, the polyester knitted fabric is introduced into the dyeing pool 1 through the guide roller 510 on the left side, and guided by the three guide rollers 12 arranged in a V shape to form an "S" shaped fabric path. Since the bottom guide roller 12 is immersed in the dye solution, it can be ensured that the polyester knitted fabric is fully soaked in the dye solution to complete the dyeing process. After the dyed polyester knitted fabric leaves the guide roller 2, it enters the area below the U-shaped plate 4. Here, high-definition cameras 5 with equal spacing can take a comprehensive and high-definition real-time picture of the surface of the dyed polyester knitted fabric. The picture captured by the high-definition camera 5 can be displayed on an external monitor so that the staff can watch it and judge whether there is a color difference on the surface of the polyester knitted fabric. When the dyed polyester knitted fabric passes through the area below the U-shaped plate 4 and is judged by the staff to have no color difference, the dyed polyester knitted fabric is guided by three guide rollers 2 3 arranged in a V-shape, and then guided out of the dyeing pool 1 in sequence through guide rollers 3 8, 4 9 and right guide roller 5 10, and can then proceed to subsequent drying and other processes. When the dyed polyester knitted fabric passes under the U-shaped plate 4 and color difference is observed by the staff, the fabric passes through three V-shaped guide rollers 3. During this process, the conveying pump 62 and two vibrating motors 76 are controlled to operate. While the conveying pump 62 is running, dye solution is drawn from the dyeing tank 1 and conveyed through the dye solution output pipe 64 to the V-shaped spray plate 65. The solution is then sprayed onto the color difference areas on the polyester knitted fabric surface through multiple nozzles 66 on both sides for secondary dyeing to effectively correct and eliminate the color difference. Simultaneously, the two vibrating motors 76 operate... In the running state, the corresponding vibrating plates 75 can be controlled to generate high-frequency vibrations in the vertical direction, which can make the polyester knitted fabric continuously and slightly shake during the secondary dyeing process, thereby breaking the surface tension of the dye liquor, promoting the penetration of dye molecules into the fiber interior, further improving the efficiency and quality of color difference correction and elimination of the polyester knitted fabric, and improving dyeing consistency. After the color difference correction is completed in the secondary dyeing (that is, when the dyed part of the polyester knitted fabric moves away from the guide roller 2 3), the conveying pump 62 and the two vibrating motors 76 are stopped, thus realizing the integrated operation process of immersion dyeing, color difference detection and uniform re-dyeing to correct color difference.
