Description

Technical Field

[0001] The present application relates to the technical field of textile production and processing, and particularly relates to a dyeing device and a dyeing method for textile production and processing. Background Art

[0002] In the process of textile production, the dyeing process is one of the key links determining the product quality. The dyeing uniformity directly affects the appearance effect, color fastness of the textile, and the consumer's use experience. When dyeing textiles, if the dye cannot uniformly penetrate into each fiber, it may lead to uneven dyeing, defects such as stripes, color spots or color differences, resulting in an unsatisfactory dyeing effect, seriously affecting the product quality, and even possibly causing a large number of defective products.

[0003] Currently, traditional textile dyeing devices generally place the fabric in a dyeing tank and perform dyeing by stirring or turning. During stirring, it is mostly driven by a motor to rotate a single-axis or multi-axis stirring rod to stir and dye the fabric placed in the dyeing tank. In this way, during the dyeing process, the fabric is continuously moved through mechanical stirring or vibration to promote the contact between the dye and the fabric. However, due to excessive fabric accumulation, the penetration of the dye is not uniform, and there may be a phenomenon of the dye staying on the fabric surface. Especially when the fabric is relatively dense, it is difficult for the dye to penetrate between each fiber, resulting in color differences in the dyeing effect. For some textiles with relatively soft or fragile textures, mechanical stirring may also cause stretching, damage or fiber damage. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 7 , a dyeing device for textile production and processing, including a dyeing box 1 and a dye tank 2 opened on the top of the dyeing box 1. The dye tank 2 is used to hold the dyeing agent. An unwinding assembly 3 for winding the textile is arranged on the top of the dyeing box 1, and the unwinding assembly 3 is placed on one side of the dye tank 2. A winding assembly 4 for winding the textile is arranged on the side of the top of the dyeing box 1 away from the unwinding assembly 3. The textile wound on the unwinding assembly 3 passes through the inside of the dye tank 2 and then winds around the outside of the winding assembly 4. Two U-shaped support frames 5 are symmetrically and fixedly installed on the top of the dyeing box 1. A support plate 6 is fixedly installed on the inner top wall of the support frame 5. A driving assembly 7 is jointly arranged on the support frame 5 and the support plate 6, and the winding assembly 4 is传动连接 with the driving assembly 7. A stretching assembly 8 for stretching the textile is arranged inside the dye tank 2. The stretching assembly 8 includes a stretching frame 81 slidably installed inside the dye tank 2. A connecting column 82 is fixedly installed on the top of the stretching frame 81. A rolling ball 83传动连接 with the driving assembly 7 is fixedly installed at the top of the connecting column 82. The driving assembly 7 is used to drive the stretching assembly 8 to reciprocate inside the dye tank 2.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 7The driving assembly 7 includes a main shaft 71 rotatably mounted on the side wall of one of the support frames 5, the winding assembly 4 is connected to the main shaft 71 in transmission, a coupling 72 is fixedly connected to one end of the main shaft 71 close to the dye tank 2, a worm 73 is fixedly connected to the output end of the coupling 72, a connecting shaft 74 is rotatably mounted between the two support plates 6, a worm wheel 75 meshing with the worm 73 is fixedly mounted on the outer side of the connecting shaft 74, an adjusting column 76 is also fixedly mounted on the outer side of the connecting shaft 74, a plurality of main slide grooves 77 and slave slide grooves 78 are provided on the outer side of the adjusting column 76, the plurality of main slide grooves 77 and slave slide grooves 78 are staggered, and both ends of the main slide groove 77 The two ends of the stretching frame 81 are symmetrically fixed with two slide bars 84 on the outside, and the inner wall of the dye tank 2 is provided with slide rails 85 which are slidably connected with each slide bar 84. When the main shaft 71 drives the worm 73 to rotate through the coupling 72, the worm 73 drives the worm wheel 75 to rotate through the meshing transmission, thereby causing the adjusting column 76 and the main slide groove 77 and the slave slide groove 78 on the outside of the adjusting column 76 to rotate. When the adjusting column 76 rotates, the sliding between the main slide groove 77 and the slave slide groove 78 and the rolling ball 83 makes the connecting column 82 and the stretching frame 81 movable. As the adjusting column 76 rotates, it moves back and forth inside the dye tank 2, thereby driving the textile to move back and forth in the horizontal direction. When the main slide groove 77 on the outside of the adjusting column 76 pushes the stretching frame 81 and the ball 83 to slide, the slide bar 84 slides inside the lower half of the slide rail 85, and when the ball 83 slides from the main slide groove 77 to the slave slide groove 78, the slide bar 84 is about to slide from the lower half of the slide rail 85 to the upper half of the slide rail 85. At this time, the traction of the slide rail 85 on the slide bar 84 causes the slide bar 84 to move upward, thereby pushing the connecting column 82 and the ball 83 to move upward, and the groove depth of the slave slide groove 78 is greater than the groove depth of the main slide groove 77. The purpose is to provide the rolling ball 83 with space for movement, so that when the stretching frame 81 stretches the textile in the horizontal direction, it can also drive the textile to shake in the vertical direction to a certain extent. When the textile shakes, it can effectively avoid the phenomenon of uneven dyeing caused by local accumulation, ensure that the dye can penetrate into every part of the textile more evenly, and avoid the problem of inconsistent dyeing caused by excessive accumulation of the textile. On the other hand, this vertical shaking also plays a positive role in the distribution of the dye. It can help the dye to be better stirred and mixed on the surface of the textile and in the solution, and avoid the accumulation or agglomeration of the dye in the dyeing liquid.

[0032] See also Figure 3A sliding column 86 is rotatably installed on the top side wall of the dye tank 2, and two traction columns 861 are symmetrically fixedly installed on the bottom side wall of the dye tank 2, and the two traction columns 861 are respectively placed on both sides of the stretching frame 81, and two squeezing columns 87 are fixedly installed on the inner side wall of the dye tank 2, and the squeezing columns 87 are placed on the side of the stretching frame 81 close to the reel 45. The textile entering the dye tank 2 first passes through the top of the sliding column 86 to the bottom of one of the traction columns 861, and then passes through the top of the stretching frame 81 to the bottom of the other traction column 861, so that the traction column 861 assists the textile in stretching when the stretching frame 81 stretches the textile, and finally passes between the two squeezing columns 87 and is fixed on the outside of the reel 45. Before being reeled up by the reel 45, the excess dye on the surface of the textile can be wiped off by the squeezing columns 87 when the textile passes through the two squeezing columns 87. Removing excess dye helps to reduce dye waste, thereby improving the use efficiency of dyes, reducing costs, and avoiding uneven dyeing or color difference.

[0033] See also Figure 5 and Figure 6 The unwinding assembly 3 includes two fixed frames 31 symmetrically fixedly mounted on the top of the dyeing box 1, an unwinding shaft 32 is rotatably mounted between the two fixed frames 31, torsion springs 33 are symmetrically fixedly connected to both ends of the unwinding shaft 32, a ratchet 35 is rotatably mounted on the inner side wall of the fixed frame 31, one end of the torsion spring 33 away from the unwinding shaft 32 is fixedly connected to the ratchet 35, a ratchet pawl 36 meshing with the ratchet 35 is rotatably mounted on the inner side wall of the fixed frame 31, a fixing ring 34 is fixedly mounted on the outer side of the unwinding shaft 32, and when the winding assembly 4 winds up the textile wound on the unwinding shaft 32, the unwinding shaft 32 is forced to rotate, and the unwinding shaft 32 rotates When the torsion spring 33 rotates, it drives the torsion spring 33 to rotate. Therefore, when the textile inside the dye tank 2 is in a certain tightness due to the movement of the stretching frame 81, the elastic force of the torsion spring 33 can make the unwinding shaft 32 rotate in the opposite direction, exerting a certain pulling force on the textile, thereby preventing the textile from accumulating inside the dye tank 2 due to failure to be reeled in in time. At the same time, when the torsion spring 33 rotates, the end away from the unwinding shaft 32 also drives the ratchet 35 to rotate. When the ratchet 35 rotates, the pawl 36 prevents it from reversing. At the same time, the ratchet 35 and the pawl 36 can be used to prevent the torsion spring 33 from reaching the maximum twisting angle when the unwinding shaft 32 rotates to discharge the material, thereby causing the unwinding shaft 32 to be unable to discharge the material normally.

[0034] See also Figure 1 and Figure 2The winding assembly 4 includes two vertical plates 41 symmetrically fixedly installed on the top of the dyeing box 1, and the vertical plates 41 are placed on the side of the dye tank 2 away from the fixed frame 31, and a motor 42 is fixedly installed on the side wall of one of the vertical plates 41 close to the main rotating shaft 71, and the output end of the motor 42 movably passes through the vertical plate 41 and is fixedly connected to the main winding shaft 43, and the main winding shaft 43 is transmission-connected to the main rotating shaft 71, and the end of the main winding shaft 43 away from the motor 42 is fixedly connected to a gearbox 44, and the gearbox 44 changes the speed of the output end by matching the gear ratios between the gears, and a slave winding shaft 45 is fixedly installed at the output end of the gearbox 44, and the main winding shaft 43 is driven to rotate by the output end of the motor 42, and then under the action of the gearbox 44, the slave winding shaft 45 is rotated at a speed less than the speed of the main winding shaft 43 to wind up the textile, and the winding speed is slow to provide time for the textile to fix the color.

[0035] See also Figure 4 and Figure 5The coupling 72 is a magnetorheological fluid transmission. The top of the dyeing box 1 is also provided with an adjustment component 9 for adjusting the moving speed of the stretching component 8. The adjustment component 9 includes a mounting box 91 fixedly mounted on the top of one of the fixed frames 31, and the mounting box 91 is placed above the end of the unwinding shaft 32 away from the fixed ring 34. A sliding rheostat 92 is fixedly installed inside the mounting box 91. The sliding rheostat 92 includes a slide 93 slidably mounted on the top of the mounting box 91. The sliding rheostat 92 is electrically connected to a DC power supply and constitutes a transmission ratio circuit. When the slide 93 slides toward the fixed ring 34, the sliding rheostat 92 is electrically connected to a DC power supply and constitutes a transmission ratio circuit. In the embodiment, the resistance of the sliding rheostat 92 in the transmission ratio circuit increases, the coupling 72 is connected to the transmission ratio circuit and connected in series with the sliding rheostat 92, an inverted L-shaped connecting rod 94 is fixedly installed on the top of the sliding plate 93, a slip ring 95 is fixedly installed on the end of the connecting rod 94 away from the sliding plate 93, the slip ring 95 is sleeved on the outside of the unwinding shaft 32 and is slidably connected to the unwinding shaft 32, a limiting column 96 is fixedly installed on the side of the installation box 91 close to the slip ring 95, and the end of the limiting column 96 away from the installation box 91 movably passes through the connecting rod 94, and a spring 97 is fixedly installed between the installation box 91 and the connecting rod 94. The spring 97 is sleeved on the outside of the limit column 96. When the textile is fixedly wound, one side of the textile fits with the fixed ring 34 and the other side fits with the slip ring 95. The textile squeezes the slip ring 95 to make the connecting rod 94 and the slide 93 slide. When the slide 93 slides on the sliding rheostat 92 toward the side away from the fixed ring 34, the resistance of the sliding rheostat 92 in the transmission ratio circuit decreases, and the current increases. The increase in current enhances the magnetic field strength of the coupling 72. The coupling 72 contains a magnetorheological fluid. The magnetorheological fluid is a fluid that can significantly change its rheological properties under the action of a magnetic field. The smart material has the following properties. As the magnetic field strength of the coupling 72 increases, the viscosity of the magnetorheological fluid is further enhanced, thereby enhancing the bonding strength between the main shaft 71 and the worm 73, increasing the rotation speed of the worm 73, and finally increasing the rotation speed of the worm wheel 75 and the adjusting column 76, thereby increasing the moving speed of the stretching frame 81, thereby matching textiles of different widths. When dyeing textiles of different widths, the dyeing efficiency will not be reduced due to the unchanged moving speed of the stretching frame 81, thereby ensuring that textiles of different widths can achieve efficient and uniform dyeing effects during the dyeing process.

[0036] Working principle:

[0037] 1. When dyeing the textile, one end of the textile is fixed and wound around the outside of the unwinding shaft 32, and the other end enters the interior of the dye tank 2 and passes through the top of the sliding column 86 to the bottom of one of the traction columns 861, and then passes through the top of the stretching frame 81 to the bottom of the other traction column 861, so that the traction column 861 assists the textile in stretching when the stretching frame 81 stretches the textile. Finally, it passes between the two squeezing columns 87 and is fixed on the outside of the secondary reel 45. The main reel 43 is driven to rotate by the output end of the motor 42, and then the secondary reel 45 is rotated at a speed less than the main reel 43 under the action of the gearbox 44 to reel the textile. The reeling speed is slow so that the textile is fixed. The color provides time, from the rotation of the winding shaft 45, the unwinding shaft 32 is forced to rotate, and the rotation of the unwinding shaft 32 drives the torsion spring 33 to rotate. Therefore, when the textile inside the dye tank 2 has a certain degree of tension due to the movement of the stretching frame 81, the elastic force of the torsion spring 33 can make the unwinding shaft 32 rotate in the opposite direction, and exert a certain pulling force on the textile, so as to prevent the textile from accumulating inside the dye tank 2 due to failure to be wound up in time. At the same time, when the torsion spring 33 rotates, the end away from the unwinding shaft 32 also drives the ratchet 35 to rotate. When the ratchet 35 rotates, the pawl 36 prevents it from reversing. At the same time, the ratchet 35 and the pawl 36 can be used to prevent the torsion spring 33 from reaching the maximum twisting angle when the unwinding shaft 32 rotates to discharge the material, causing the unwinding shaft 32 to be unable to discharge the material normally;

[0038] 2. The main winding shaft 43 drives the main shaft 71 to rotate through the transmission connection. When the main shaft 71 drives the worm 73 to rotate through the coupling 72, the worm 73 drives the worm wheel 75 to rotate through the meshing transmission, thereby causing the adjusting column 76 and the main slide groove 77 and the slave slide groove 78 provided on the outer side of the adjusting column 76 to rotate. When the adjusting column 76 rotates, the sliding between the main slide groove 77 and the slave slide groove 78 and the ball 83 enables the connecting column 82 and the stretching frame 81 to reciprocate inside the dye tank 2 as the adjusting column 76 rotates, thereby driving the textile to reciprocate in the horizontal direction. When the stretching frame 81 and the ball 83 are pushed to slide by the main slide groove 77 on the outer side of the adjusting column 76, the slide rod 84 slides inside the lower half of the slide rail 85, and when the ball 83 slides from the main slide groove 77 to the slave slide groove 78, the slide rod 84 is about to slide from the lower half of the slide rail 85 to the slide rail 85 The upper part of the slide rail 85 at this time pulls the slide bar 84 to make the slide bar 84 move up, thereby pushing the connecting column 82 and the rolling ball 83 to move up, and the slot depth of the secondary slide groove 78 is greater than the slot depth of the main slide groove 77, just to provide a space for the rolling ball 83 to move, so that when the stretching frame 81 stretches the textile in the horizontal direction, it can also drive the textile to shake in the vertical direction to a certain extent, and when the textile shakes, it can effectively avoid the phenomenon of uneven dyeing caused by its local accumulation, ensure that the dye can penetrate more evenly into each part of the textile, and reduce the problem of inconsistent dyeing caused by excessive accumulation of textiles. On the other hand, this vertical shaking also plays a positive role in the distribution of the dye, which can help the dye to be better stirred and mixed on the surface of the textile and in the solution, and avoid the phenomenon of accumulation or agglomeration of the dye in the dyeing solution;

[0039] 3. When the textile is fixedly wound, one side of the textile fits with the fixed ring 34, and the other side fits with the slip ring 95. Therefore, the textile squeezes the slip ring 95 to make the connecting rod 94 and the slide 93 slide. When the slide 93 slides on the sliding rheostat 92 toward the side away from the fixed ring 34, the resistance of the sliding rheostat 92 in the transmission ratio circuit decreases, and the current increases. The increase in current enhances the magnetic field strength of the coupling 72. The coupling 72 contains magnetorheological fluid inside. As the magnetic field strength of the coupling 72 increases, the viscosity of the magnetorheological fluid is further enhanced, and the bonding strength between the main shaft 71 and the worm 73 is enhanced, thereby increasing the rotation speed of the worm 73, and finally increasing the rotation speed of the worm wheel 75 and the adjusting column 76, thereby increasing the moving speed of the stretching frame 81, and then matching textiles of different widths. When textiles of different widths are dyed, the dyeing efficiency will not be reduced due to the unchanged moving speed of the stretching frame 81, ensuring that textiles of different widths can achieve efficient and uniform dyeing effects during the dyeing process.

[0040] A dyeing method of a dyeing device for textile production and processing, comprising the following processing steps:

[0041] S1, fix one end of the textile to be processed and wind it around the outside of the unwinding shaft 32, and then pass the other end of the textile around the sliding column 86, the traction column 861 and the stretching frame 81 inside the dye tank 2 in sequence, and finally pass through between the two squeezing columns 87 and be fixedly installed on the outside of the reeling shaft 45;

[0042] S2, during the process of slowly winding the textile by the motor 42, the gearbox 44 and the reel 45, the textile immersed in the dye in the dye tank 2 is reciprocated left and right by the action of the stretching frame 81 under the action of the driving component 7 and the stretching component 8, and the dye can be more evenly covered on the surface of the textile by stretching the textile;

[0043] S3. During dyeing, under the action of the adjusting component 9, the driving component 7 and the stretching component 8 have different operating speeds when dyeing textiles of different widths, thereby being able to change the dyeing speed of the stretching frame 81 according to the width of the textiles, thereby making the dyeing efficiency of the textiles higher.

[0044] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
