Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing technology, and specifically to a printing and dyeing technology. Background Art

[0002] The printing and dyeing of fabrics is a delicate and complex process that aims to evenly attach colors to fabrics. The printing and dyeing of fabrics not only gives fabrics bright colors, but also significantly improves their visual and tactile effects. Through modern printing and dyeing technologies, fabrics can present a variety of complex patterns and delicate color levels. These technologies include digital printing and screen printing, which can achieve high-precision pattern printing with bright and long-lasting colors. With the development of technology, printing and dyeing operations have become more environmentally friendly and efficient. The use of new dyes and auxiliaries reduces the burden on the environment, while improved processes can better save water and energy. Modern printing and dyeing can also achieve enhanced fabric properties, such as UV resistance, dirt resistance and enhanced wear resistance, so that fabrics are not only improved in appearance, but also improved in functionality. Overall, the progress of printing and dyeing operations not only improves the aesthetic effect of fabrics, but also promotes the goal of sustainable development, in line with the needs of modern consumers for environmentally friendly and high-quality products.

[0003] In the prior art, a Chinese invention patent with the announcement number "CN115110229B" discloses an environmentally friendly dyeing and printing pool for strengthening continuous dyeing and printing, comprising a dyeing and printing pool body, a feed inlet is provided at the top right side of the dyeing and printing pool body, a feed device is provided at the feed inlet, a discharge port is provided at the left side of the dyeing and printing pool body, a discharge device is provided in the discharge port, a swing device is provided below the mutually opposite sides of the feed inlet and the discharge port, two sets of the swing devices are both located inside the dyeing and printing pool body, and a swing device is provided in the middle of the front and rear sides of the dyeing and printing pool body. A filtering device is provided, and the filtering device includes a filter box, a cover plate, a pressure pump, an air inlet pipe, a water inlet pipe, a material placement table, a spray pressure pipe and a protective cover. The filter box is arranged in the middle of the side wall of the printing and dyeing tank body, the cover plate is arranged on the top of the filter box, and the connection between the two is rotatably connected to each other, the pressure pump is arranged on the top of the cover plate, the air inlet pipe is arranged at both ends of the pressure pump and is connected to the inside of the filter box, the water inlet pipe is plugged at both sides of the bottom of the filter box and is connected to the inside of the printing and dyeing tank body, the material placement table is arranged at the bottom of the inner cavity of the printing and dyeing tank body, and a plurality of the spray pressure pipes are provided. The pressure tube is plugged into the surface of the material placement table, and the bottom is connected to the water inlet pipe. The protective cover is sleeved on the bottom of the material placement table. Slide blocks are provided at the corresponding slide grooves on both sides of the protective cover. Openings are provided at the bottoms of the left and right sides of the protective cover. Auxiliary material rollers are provided at the openings. The input ends on both sides of the filter device are plugged into the inside of the printing and dyeing pool body. Slide grooves are provided on both sides of the inner wall of the printing and dyeing pool body corresponding to the plug-in place of the filter device. Water supply devices are provided on the left and right sides of each of the filter devices. The input end of the water supply device is plugged into the inside of the printing and dyeing pool body. The water supply device includes a fixed frame, a water pump, a water suction pipe, a water supply pipe and a liquid collecting cover. The fixed frame is arranged on one side of the outside of the printing and dyeing tank body and is located on the side of the filtering device. The water pump is connected to the top of the fixed frame. One end of the water suction pipe is interconnected with the water pump, and the other end of the water suction pipe is plugged into the interior of the printing and dyeing tank body and is interconnected with the liquid collecting cover. The liquid collecting cover is arranged inside the printing and dyeing tank body and has multiple liquid inlets on the surface. One end of the water supply pipe is interconnected with the other end of the water pump, and the other end of the water supply pipe is connected to the filtering device.

[0004] This technology uses a water circulation method to make the dye liquid in the printing and dyeing tank flow from top to bottom through a pressure pump. The dye liquid is filtered through multiple layers of filters to effectively isolate impurities, thereby improving the filtering effect and extending the service life. However, this technology still has some problems. When the cloth flows in the dye liquid, it will produce impact, pushing the dirt to flow with the dye liquid. Since the pressure pump only extracts the dye liquid from a fixed position in the printing and dyeing tank, this may reduce the filtering effect of the filter box on the dirt. Although the filter box uses multiple layers of filters to filter dirt, the top layer of the filter screen bears the most dirt. Once blocked, it will affect the effect of the entire filtration system, while the bottom layer of the filter screen is not fully put into use. This forces workers to regularly maintain and replace the filter screen, increasing maintenance costs and operating difficulties. In addition, the fabric is dyed only by soaking in the printing and dyeing tank, which prolongs the printing and dyeing time and reduces the dyeing effect. Summary of the invention

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 to Figure 9 As shown, this embodiment proposes a printing and dyeing process, including the following process steps: S100: Pretreatment: washing the fabric to remove dirt and grease, bleaching to remove natural pigments, ensuring that the dye can adhere evenly and improve the dyeing effect; S200: Batching: Accurately prepare dyes and auxiliaries to ensure that the concentration and performance of the mixture meet dyeing requirements; S300: printing and dyeing; the fabric 1 is sent to the printing and dyeing device for printing and dyeing, ensuring that the dye fully penetrates to achieve the desired color effect, and the dye is firmly combined with the fiber through the high temperature to prevent the color from fading or transferring, thereby ensuring the durability of the color; When the fabric 1 is printed and dyed by the printing and dyeing device, the dyeing effect of the fabric 1 is improved, and the dirt generated by the mixing of the fabric 1 and the dyeing liquid is better cleaned, and the dyeing liquids of different depths can be cleaned, so that the dirt will not be accumulated in the printing and dyeing device for a long time, and the exchange effect between the fabric 1 and the dyeing liquid is improved. Secondly, the filtering effect of the dyeing liquid is guaranteed by the filtering component, and each layer of the filter screen 23 in the filtering component can be fully put into use, which reduces the later maintenance cost of the filtering component, that is, reduces the use cost of the equipment; S400: washing: washing the dyed fabric 1 with water to remove excess dye and chemical residues, thereby improving the cleanliness and color uniformity of the fabric 1; S500: Drying: Drying the washed fabric 1 at a controlled temperature to remove moisture and ensure that the dye is stable and the fabric is not deformed:; S600: Post-treatment: finishing the dried fabric 1, such as wrinkle removal and shaping, to improve the appearance and feel of the fabric so that it meets the final use standard; S700: Quality Inspection: Check the dyed fabric1 to ensure that the color is uniform, free of defects, and meets the predetermined quality standards and customer requirements.

[0020] like Figure 1 to Figure 9 As shown, step S300 printing and dyeing includes:

[0021] S310: feeding the fabric 1 into the printing and dyeing device, so that both ends of the fabric 1 are tightened by the unwinder and the winder respectively, and under the synchronous rotation of the unwinder and the winder, the fabric 1 is slowly passed through the printing and dyeing device for printing and dyeing; Through the tensioning effect of the unwinder and the winder on the fabric 1, the fabric 1 can better cooperate with the oscillating component in the printing and dyeing device during the printing and dyeing process, that is, it can better exchange with the dye liquid, that is, the dyeing effect of the fabric is improved, and the dyeing efficiency of the fabric 1 is improved; S320: while the printing and dyeing device is printing and dyeing the fabric 1, the fabric 1 is stretched and beaten, and the dyeing liquid in the printing and dyeing device is circulated and filtered; The stretching effect of the fabric in the oscillating component enables the fibers of the fabric 1 to better exchange with the dye solution. At the same time, the dirt on the fabric 1 can also be better cleaned, ensuring the neatness of the dye solution, so that the same batch of dye solution can be used for dyeing operations with more sections of fabric 1, reducing the cost of use.

[0022] like Figure 1 to Figure 9 As shown, the printing and dyeing device in step 300 includes a printing and dyeing housing 21, the lower side of the printing and dyeing housing 21 is fixedly connected to the return water housing 22, and the return water housing 22 is fixedly connected to a plurality of downwardly inclined filter screens 23, two drain grooves 211 are respectively provided on the side walls of the printing and dyeing housing 21, the printing and dyeing housing 21 and the return water housing 22 are connected through the drain grooves 211, and the uppermost filter screen 23 is lower than the drain grooves 211; One side of the water return housing 22 is fixedly connected to two water pumps 24 that refill the water in the water return housing 22 into the printing and dyeing housing 21. The water inlet pipe of the water pump 24 is connected to the space at the bottom of the water return housing 22. The water outlet pipe of the water pump 24 is connected to the side wall of the printing and dyeing housing 21. The bottom of the water return housing 22 is fixedly connected to the support frame 25. The oscillating assembly for oscillating the fabric 1 is connected to the printing and dyeing housing 21; A driving assembly for driving the oscillating assembly is connected to the upper side of the printing and dyeing housing 21; The oscillation component can oscillate and stretch the fabric 1 immersed in the high-temperature dye solution, which can help the dye to be more evenly distributed in the fabric 1, so that the dye can penetrate deeper into the fiber, reducing color difference and unevenness. The oscillation stretching can increase the contact area between the dye and the fiber of the fabric 1, thereby increasing the adsorption rate of the dye, which helps to improve the dyeing effect and reduce wrinkles after printing and dyeing. The fabric 1 will be straightened during the stretching process, which helps to maintain its flatness and smoothness. The oscillation stretching can increase the penetration speed and uniformity of the dye during the dyeing process, thereby shortening the dyeing time and improving production efficiency. Secondly, the fabric 1 During the printing and dyeing process, the water level of the dye liquid can also be driven to move, so that the dirt mixed in the dye liquid of different depths can be cleaned, and the dirt in the dye liquid can be cleaned better. Finally, when the dye liquid passes through a plurality of downwardly inclined filter screens 23, even when the top filter screen 23 is blocked, the dye liquid can still flow downward along the inclined surface of the filter screen 23, so that the next filter screen 23 performs filtering work, and then the plurality of filter screens 23 can produce a filtering effect, so that the plurality of filter screens 23 can be disassembled, cleaned and used simultaneously, thereby ensuring the filtering effect, and increasing the maintenance cycle of the filter screen 23, thereby reducing the maintenance cost of the equipment.

[0023] like Figure 1 and Figure 4~Figure 8As shown, the oscillation assembly includes two lifting seats 31, each lifting seat 31 is fixedly connected to the upper side of the printing and dyeing housing 21, two limit rods 32 are fixedly connected to the lifting seats 31, a transmission screw 33 is rotatably connected between the two limit rods 32, a transmission block 34 is threadedly connected to the transmission screw 33, and the transmission block 34 is slidably connected to the two limit rods 32; One end of the two transmission blocks 34 facing the inner wall of the printing and dyeing housing 21 is fixedly connected to the first bearing plate 351 and the second bearing plate 352 respectively, each water return seat 36 is slidably connected to the lower end of the first bearing plate 351 and the second bearing plate 352, and the transmission groove 361 is provided on the water return seat 36, and the lower ends of the first bearing plate 351 and the second bearing plate 352 are both in contact with the inner wall of the transmission groove 361; The lower ends of the two water return seats 36 are fixedly connected to the water return plate 37, and the water return plate 37 is tightly in contact with the inner wall of the printing and dyeing housing 21; A buffer component for buffering the fabric 1 immersed in the dye solution under the action of tension is connected between the lower ends of the first bearing plate 351 and the second bearing plate 352; A stirring assembly that cooperates with the buffer assembly to stir the dye liquid in the printing and dyeing housing 21 is connected to both sides of the buffer assembly; The oscillation component can perform oscillation stretching on the fabric 1 in the dye solution through components. Oscillation stretching can help the dye to be more evenly distributed in the fabric 1. This is because during the stretching process, the fibers of the fabric 1 will unfold, allowing the dye to penetrate deeper into the fibers, reducing color difference and unevenness. The oscillation stretching can increase the contact area between the dye and the fibers of the fabric 1, thereby increasing the adsorption rate of the dye, which helps to improve the dyeing effect and make the color brighter and more durable. The dye can penetrate into the fibers of the fabric 1 more evenly, which helps to improve the fastness of the dyeing. In this way, the dyed fabric 1 is not easy to fade or discolor, thereby extending the service life of the fabric 1 and reducing wrinkles after printing and dyeing. The fabric 1 will be straightened during the stretching process, which helps to maintain its flatness and smoothness. In addition, the oscillation stretching can increase the penetration speed and uniformity of the dye during the dyeing process, thereby shortening the dyeing time and improving production efficiency.

[0024] like Figure 1 and Figure 4~Figure 8 As shown, the buffer assembly includes two connecting blocks 41, each connecting block 41 is fixedly connected to the adjacent first bearing plate 351 or second bearing plate 352, each buffer seat 42 is fixedly connected to the upper side of each connecting block 41, two reset plates 43 are fixedly connected to each buffer seat 42, and a partition plate 44 is fixedly connected between the two reset plates 43; The reset column 45 is fixedly connected to the two reset plates 43, and the two linkage plates 46 are sleeved on each reset column 45, and the buffer sleeve 47 is rotatably connected between the coaxial linkage plates 46 on both sides; Two buffer springs 48 are sleeved on each reset column 45, and two ends of each buffer spring 48 are respectively in contact with the partition plate 44 and the linkage plate 46; When the stretching rollers 52 on both sides move the fabric 1 in the opposite direction, that is, the stretching rollers 52 have a stretching effect on the fabric 1, the tension of the fabric 1 itself can drive the two buffer sleeves 47 to move toward each other, and then the stretching effect of the stretching roller 52 on the fabric 1 is reduced by the two moving buffer sleeves 47, preventing the fabric 1 from being damaged due to excessive pulling force, ensuring the tension of the fabric 1 itself, so that the fabric 1 can better exchange with the dye solution, and then when the stretching rollers 52 on both sides move toward each other, that is, the stretching rollers 52 do not have a stretching effect on the fabric 1, the two buffer sleeves 47 maintain the tension of the fabric 1 through the buffer springs 48 on both sides, so that the fabric 1 can smoothly exchange with the dye solution.

[0025] like Figure 2~Figure 7 As shown, the stirring assembly includes two first linkage plates 51, each of which is slidably connected to the upper side of the printing and dyeing housing 21, each of which is rotatably connected to each stretching roller 52, and one end of each stretching roller 52 away from the first linkage plate 51 is rotatably connected to each second linkage plate 53, and each of which is slidably connected to the upper side of the printing and dyeing housing 21; The stirring cylinder 54 with fan blades is rotatably connected between the first linkage plate 51 and the second linkage plate 53 which are coaxially arranged. One end of the stirring cylinder 54 facing the first linkage plate 51 is fixedly connected to the linkage gear 55. The linkage gear 55 is meshed with the linkage rack 56. The linkage rack 56 is fixedly connected to the inner wall of the printing and dyeing housing 21. The second linkage plate 53 is hinged to the transmission plate 57 at one side away from the stirring cylinder 54, and the transmission plate 57 is hinged to the second bearing plate 352 at one end away from the second linkage plate 53; When the coaxially arranged first linkage plate 51 and the second linkage plate 53 move left and right, the stretching roller 52 can drive the fabric 1 wound on the stretching roller 52 to stretch, so that the fabric 1 can better exchange with the dye liquid in the high-temperature dye liquid, thereby improving the dyeing effect of the fabric 1. At the same time, the movement can also drive the relatively moving linkage gear 55 and the linkage rack 56 to move, so that the linkage gear 55 rotates, and then drives the stirring drum 54 coaxially fixedly connected to the linkage gear 55 to rotate. The rotation of the stirring drum 54 can print and dye the inside of the housing 21. The dye liquor is stirred to prevent the dye in the dye liquor from precipitating out easily, and the dirt attached to the fabric 1 can be washed off, thereby ensuring the printing and dyeing of the fabric 1. The dirt in the dye liquor will continue to flow, and then when the liquid level of the dye liquor continues to rise, the dirt of different depths in the dye liquor will be filtered outward through the drain trough 211, thereby ensuring the overall cleanliness of the dye liquor, that is, improving the exchange effect between the dye liquor and the fabric 1. Secondly, the fan blades on the rotating stirring cylinder 54 can also beat the surface of the fabric 1 on one side which is under tension, thereby further improving the exchange effect between the fabric 1 and the dye liquor.

[0026] like Figure 1 and Figure 8 As shown, the driving assembly includes a plurality of bearing seats 61, each bearing seat 61 is fixedly connected to the upper side of the printing and dyeing housing 21, a bearing plate 62 is fixedly connected to the upper side of each bearing seat 61, two first synchronous wheels 63 are rotatably connected to the bearing plate 62, and each first synchronous wheel 63 is coaxially fixedly connected to the adjacent transmission screw 33; The second synchronous wheel 64 is connected between the two first synchronous wheels 63, and the second synchronous wheels 64 are rotatably connected to the upper side of the bearing plate 62, and the synchronous belt 65 is meshed on the second synchronous wheel 64 and the two first synchronous wheels 63; The protective sleeve 66 is fixedly connected to the load-bearing plate 62, the driving motor 67 is fixedly connected to the protective sleeve 66, and the driving shaft of the driving motor 67 is coaxially fixedly connected to the second synchronous wheel 64; The protective cover 66 is used to protect the components between the load-bearing plate 62 and the protective cover 66; Through the transmission of the second synchronous wheel 64 and the two first synchronous wheels 63 and the synchronous belt 65, the transmission screws 33 on both sides are driven to rotate synchronously, so that the return plate 37 can move up and down stably in the printing and dyeing shell 21, thereby reducing the oscillation amplitude of the dye liquid due to the movement of the return plate 37, making the dye liquid tend to be stable, and preventing the dye liquid from affecting the work workshop outside the printing and dyeing shell 21.

[0027] like Figure 2 and Figure 3 As shown, the length of the side wall of the transmission groove 361 is less than half the length of the transmission screw 33; The transmission screw 33 drives the transmission block 34 to move upward more than half the distance before it can move the return water seat 36 upward, and then the water level of the dye pool in the printing and dyeing shell 21 is raised through the return water plate 37, so that the dirt mixed in the dye liquor of different depths can be cleaned, thereby increasing the cleaning effect of the dirt in the dye liquor.

[0028] The principle of this embodiment is: The fabric 1 is fed into the printing and dyeing device for printing and dyeing operation, so that the two ends of the fabric 1 are respectively tightened by the unwinder and the winder, and the fabric 1 is slowly passed through the printing and dyeing device for printing and dyeing under the synchronous rotation of the unwinder and the winder. The unwinder and the winder tighten the fabric 1, so that the fabric 1 can better cooperate with the oscillation component in the printing and dyeing device during the printing and dyeing process. The driving component rotates synchronously with the transmission screws 33 on both sides, thereby driving the buffer seat 42 to move, so that the buffer sleeves 47 on the two buffer seats 42 can pull the fabric 1. When the two buffer seats 42 move in a direction away from the upper side table of the printing and dyeing housing 21, the movement away from the table here includes movement in two directions, downward and upward; When moving downward, due to the tension of the fabric 1 itself, when the fabric 1 is stretched, the fabric 1 is prevented from being damaged by excessive pulling force. The two moving buffer sleeves 47 reduce the stretching effect of the stretching roller 52 on the fabric 1, so that the fabric 1 is always in a straight state. When the coaxially arranged first linkage plate 51 and the second linkage plate 53 move left and right, the stretching roller 52 can drive the fabric 1 wound on the stretching roller 52 to stretch, so that the fabric 1 can better exchange with the dye liquid in the high-temperature dye liquid, thereby improving the dyeing effect of the fabric 1. At the same time, the movement can also drive the relatively moving linkage gear 55 and the linkage rack 56 to move, so that the linkage gear 55 rotates, and then drives the stirring drum 54 coaxially fixedly connected with the linkage gear 55 to rotate. The rotation of the stirring drum 54 can stir the dye liquid in the printing and dyeing shell 21, so that the dye in the dye liquid is not easy to precipitate, and the dirt attached to the fabric 1 can be washed off, so as to ensure the printing and dyeing of the fabric 1, and the dirt in the dye liquid will flow continuously; When moving upward, it means that the first bearing plate 351 and the second bearing plate 352 have abutted against the uppermost inner wall of the transmission groove 361, so the movement of the first bearing plate 351 and the second bearing plate 352 will move the return plate 37, thereby causing the liquid level of the dye to rise continuously, so that the dirt of different depths of the dye is filtered outward through the drain groove 211, thereby ensuring the overall cleanliness of the dye, that is, improving the exchange effect between the dye and the fabric 1. Secondly, the fan blades on the rotating stirring cylinder 54 can also beat the surface of the fabric 1 on one side that is under tension, further improving the exchange effect between the fabric 1 and the dye; In order to achieve the dyeing effect of the fabric 1 in daily life, the driving screw 33 only needs to rotate back and forth halfway, and then when the dye liquor needs to be filtered, the full stroke of the driving screw 33 is put into use.
