Description

Technical Field

[0001] The present invention relates to the field of dipping equipment, and particularly to a dipping equipment for nylon cloth production that can improve the dipping effect. Background Art

[0002] In the traditional marbling process, unique textures are formed in the dipping of nylon cloth through water transfer printing technology. Its core relies on manual control of the flow of oil-based dyes on the water surface and pattern generation. In the specific process, the operator needs to manually drop the dyes into the water drop by drop, and then use tools such as a painting comb and a needle stick to guide the diffusion of the dyes through actions such as swiping and stirring to generate unique patterns. Finally, the nylon cloth is immersed in the water to complete the transfer printing.

[0003] However, the traditional marbling process has long been limited by the following defects in industrial applications. First, pattern making highly depends on experienced masters to complete manually. The operator needs to repeatedly drag a painting comb on the liquid surface to form specific textures. However, the randomness of manual operation makes it difficult to precisely control the flow state of the dyes, and it is impossible to achieve the directional generation and batch reproduction of textures. For example, differences in the swiping angle and strength of the painting comb will directly affect the diffusion path of the dyes, resulting in uncontrollable fluctuations in the complexity and artistry of the patterns. In addition, manual operation is difficult to standardize, and technical differences between different operators easily lead to uneven product quality, severely restricting the stability of large-scale production. Second, when switching between multiple colors, it is necessary to completely remove the residual oil-based dyes on the liquid surface. Otherwise, the mixing of new and old dyes will cause cross-contamination and affect the dyeing consistency. Currently, this process completely relies on manual completion, and the operator needs to manually scrape off the floating dyes. However, manual scraping is prone to missing the corner areas or not completely removing the tiny dye particles sinking into the water. The residual pollutants not only increase the risk of color difference in subsequent batches, but also lead to dye waste and an increase in wastewater treatment costs. Frequent manual intervention significantly prolongs the production cycle and reduces the overall efficiency. Finally, the fixed discharge port of the traditional dipping equipment cannot automatically adjust according to the change in the liquid surface height, resulting in problems such as dye overflow or incomplete removal during the scraping process, further affecting the production efficiency and dyeing quality.

[0004] Based on the above situation, there is an urgent need to develop a dipping equipment integrating intelligent material leveling, dynamic scraping, and adaptive discharging functions to break through the bottleneck of manual efficiency and achieve the industrial production goals of controllable textures, efficient dye removal, and rapid multi-color switching. Summary of the Invention

Detailed implementation manners

[0029] The following is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention accordingly.

[0030] Embodiment 1: A dipping device for producing nylon cloth that can improve the dipping effect, as Figures 1-5 shown, including a dipping pool 1 for containing drawing liquid and oil-based dyes and providing a dye diffusion environment required for the wet transfer painting process; a valve is installed on the outer wall of the dipping pool 1 to facilitate the discharge of the liquid material and ensure convenient cleaning and maintenance of the equipment; a guide rod 111 is fixedly connected to the outer wall of the dipping pool 1, and a servo motor 11 is installed on the dipping pool 1. The output shaft of the servo motor 11 is fixedly connected to a driving lead screw 12 through a coupling for providing precise power transmission; the driving lead screw 12 is rotatably connected to the guide rod 111, and a moving frame 13 is threadedly connected to the driving lead screw 12 and horizontally slides on the guide rod 111. A moving member 17 is slidably connected to the guide rod 111 and is in contact with the moving frame 13. When the moving frame 13 moves to the right, it will push the moving member 17 to move synchronously. A sliding rod 1501 is slidably connected to the moving member 17, and a first painting comb 15 is slidably connected to the sliding rod 1501. It can slide back and forth on the drawing liquid as the moving member 17 moves horizontally, guiding the diffusion of the dye to generate a unique pattern; symmetrically distributed grooves are formed on the sides of the moving frame 13 and the moving member 17 close to each other, and adsorption magnets 110 are provided in each groove. Through magnetic attraction cooperation, it is ensured that the moving frame 13 and the moving member 17 move synchronously.

[0031] When using the wet transfer painting process to transfer and dip the nylon cloth, an appropriate amount of water, methyl cellulose or ox bile is added to the dipping pool 1 to prepare the drawing liquid to form a stable suspension medium layer. Adjust the height of the drawing liquid to a position where the pins of the first painting comb 15 are slightly submerged to ensure that the painting comb can fully contact the drawing liquid, thereby effectively guiding the diffusion of the dye.

[0032] Precisely drop various oil-based dyes onto the surface of the drawing liquid, and initially diffuse under the action of the suspension medium layer to lay a foundation for subsequent pattern generation. Start the servo motor 11, and its output shaft drives the driving lead screw 12 to rotate forward and backward through the coupling, driving the moving frame 13 to horizontally slide along the guide rod 111. The moving frame 13 drives the moving member 17, the sliding rod 1501 and the first painting comb 15 to move left and right synchronously through magnetic attraction cooperation, realizing precise control of the dye diffusion and ensuring the quality and consistency of pattern generation. The first painting comb 15 slides back and forth on the drawing liquid, guiding the uniform diffusion of the dye to form a unique and consistent pattern. Steadily immerse the nylon cloth into the drawing liquid to complete the transfer and dipping process of the wet transfer painting process, ensuring that the dye pattern is completely transferred to the cloth surface.

[0033] In the ebru process, in order to generate diverse patterns and meet the requirements of their complexity and fineness, it is necessary to flexibly switch between combs with different tooth pitches during the production process. For example, the first comb 15 with a larger tooth pitch is used for the initial stroke, and the second comb 16 with a smaller tooth pitch is used for the second stroke. However, there is currently a lack of an efficient automated structure and operation process to meet this requirement. Existing technologies usually rely on manual replacement or adjustment of the combs, which not only increases the operation difficulty but also may lead to a decrease in pattern consistency. Therefore, it is necessary to design a comb switching mechanism with a higher degree of automation to improve operation convenience, pattern consistency, and production efficiency.

[0034] As Figure 4 and Figure 5 shown, specifically, a rotating lead screw 19 is rotatably connected to the moving member 17 for adjusting the height of the comb. The sliding rod 1501 is threadedly connected to the rotating lead screw 19. When the rotating lead screw 19 is turned, it can drive the sliding rod 1501 threadedly connected thereto to move up and down in the vertical direction, thereby precisely controlling the lifting action of the first comb 15 so that it can smoothly withdraw from or enter the painting liquid.

[0035] In addition, a second comb 16 is slidably connected to the moving member 17, located above the first comb 15, and is distributed in a staggered up and down manner. In order to achieve the linkage between the two combs, symmetrically distributed connecting ropes 18 are connected between the first comb 15 and the second comb 16, and the connecting ropes 18 pass through the moving member 17.

[0036] After the first comb 15 completes the initial stroke, by turning the rotating lead screw 19, the sliding rod 1501 threadedly connected thereto is driven to move upward in the vertical direction. The upward movement of the sliding rod 1501 drives the entire first comb 15 to rise smoothly, so that it completely withdraws from the painting liquid.

[0037] As the first comb 15 withdraws, the connecting ropes 18 are in a slack state. At this time, under the action of its own gravity, the second comb 16 moves downward along the sliding connection track on the moving member 17 and accurately enters the painting liquid. Subsequently, by controlling the servo motor 11 to drive the driving lead screw 12 to rotate, the moving frame 13 together with the moving member 17 and the second comb 16 move back and forth in the horizontal direction. During this process, the second comb 16 completes the second stroke on the painting liquid, further optimizing the dye distribution, and finally generating the target pattern.

[0038] As described in the background art, after the transfer and immersion of the wet transfer painting process on the nylon cloth, the oily dyes remaining on the liquid surface need to be completely removed. However, the existing manual scraping method has the following problems: it is easy to miss the corner areas, resulting in incomplete removal of some residual dyes; manual operation takes a long time and is difficult to meet the actual needs of efficient production. Therefore, to solve the above problems, an automated scraping mechanism needs to be designed, which can efficiently and comprehensively remove the oily dyes remaining on the liquid surface, reduce the waste of the painting liquid itself, and ensure the smooth and reliable cleaning process.

[0039] Specifically, an L-shaped scraper for scraping the residual dyes on the liquid surface is provided on the second painting comb 16. A discharge window for discharging the residual dyes and excess painting liquid is opened on the side wall of the immersion tank 1 near the servo motor 11. A closing plate 112 is slidably connected to the immersion tank 1 near the discharge window. A closing cloth 113 with a certain margin is fixedly connected to the top wall of the discharge window, and its movable end is fixedly connected to the closing plate 112 to ensure that the closing cloth 113 can expand and contract as it moves and maintain a sealed state when the closing plate 112 moves.

[0040] As Figure 3 and Figure 6 As shown, a hollow connecting frame 114 is fixedly connected between the closing plate 112 and the closing cloth 113. A discharge port for discharging the residual dyes is opened on its bottom wall. The connecting frame 114 can slide vertically on the immersion tank 1 to adjust the height matching between the discharge port and the liquid surface. A moving plate 115 is slidably connected inside the connecting frame 114, and the opening and closing of the discharge port are controlled by the horizontal movement of the moving plate 115, so as to flexibly adjust the discharging process.

[0041] After the transfer and immersion of the wet transfer painting process on the nylon cloth, the oily dyes remaining on the liquid surface need to be removed. Initially, the connecting frame 114 is vertically moved to a position flush with the liquid surface. First, the moving plate 115 is pulled to the right to disengage it from the discharge port on the bottom wall of the connecting frame 114, thus opening the discharge channel.

[0042] Continue to turn the rotating lead screw 19 to further move the first painting comb 15 upward. At the same time, the second painting comb 16 moves downward under its own gravity until the horizontal part of the L-shaped scraper on it enters the painting liquid. Then, start the servo motor 11 to drive the driving lead screw 12 to rotate, and drive the moving frame 13 to drive the moving member 17 and the second painting comb 16 to move horizontally to the right together.

[0043] During this process, the L-shaped scraper on the second painting comb 16 will push the upper layer of painting liquid and floating oily dyes into the connecting frame 114 and discharge them out of the immersion tank 1 through the discharge port. When all the residual oily dyes are discharged, the moving plate 115 is pushed back to its original position to re-seal the discharge port of the connecting frame 114 and prevent the painting liquid from continuing to flow out.

[0044] During the material discharging process, some drawing liquid is carried out, resulting in a decrease in the liquid level height. At this time, the connecting frame 114 is moved downward to a position flush with the new liquid level height, and the sealing cloth 113 extends downward accordingly to adapt to the liquid level change. Finally, the servo motor 11 is controlled to rotate reversely, driving the moving frame 13 together with the moving member 17 and the second drawing comb 16 to move leftward and reset, completing the entire cleaning process.

[0045] A T-shaped rod 120 for support and guidance is fixedly connected to the side wall of the dipping pool 1. A transmission rod 116 is slidably connected thereto. The moving plate 115 slides vertically on the transmission rod 116, capable of controlling the opening and closing of the material discharging port of the connecting frame 114. A return spring 121 is connected between the transmission rod 116 and the dipping pool 1. The return spring 121 is wound around the T-shaped rod 120, used to provide elastic force to ensure the automatic reset function of the transmission rod 116 and the moving plate 115. The top of the second drawing comb 16 is fixedly connected with a pressing plate 14, which forms a pressing fit with the transmission rod 116. During the movement of the second drawing comb 16, the transmission rod 116 is pushed by the pressing plate 14, thereby realizing the opening and closing control of the material discharging port by the moving plate 115.

[0046] When the second drawing comb 16 moves to the right, the pressing plate 14 fixedly connected to its top also moves to the right. When the pressing plate 14 contacts the transmission rod 116, it will push the transmission rod 116 to slide to the right, thereby driving the moving plate 115 to move to the right, automatically opening the material discharging port of the connecting frame 114. At this time, the return spring 121 undergoes elastic deformation due to the force.

[0047] When the second drawing comb 16 moves leftward to reset, the pressing plate 14 at its top also moves leftward and disengages from the transmission rod 116. At this time, under the elastic force of the return spring 121, the transmission rod 116 drives the moving plate 115 to move leftward to reset, thereby closing the material discharging port of the connecting frame 114 again.

[0048] A rotating lead screw 119 for driving the connecting frame 114 to move up and down to adapt to the liquid level height is rotatably connected to one side of the dipping pool 1 near the T-shaped rod 120. The connecting frame 114 is threadedly connected to the rotating lead screw 119, and precise height adjustment is achieved through threaded transmission. A one-way gear 118 with a one-way transmission function and preventing reverse rotation is slidably and self-locked in the rotating lead screw 119 to ensure that the system will not have an unexpected reverse action due to an external torque during operation. A connecting rack 117 is fixedly connected to the transmission rod 116. The one-way gear 118 meshes with the connecting rack 117 to form a gear transmission system for converting horizontal motion into vertical motion.

[0049] As described above, when the transmission rod 116 moves to the right, the connecting rack 117 thereon moves to the right accordingly. At this time, the one-way gear 118 and the rotating lead screw 119 remain stationary and do not perform any actions. When the transmission rod 116 drives the connecting rack 117 to move leftward for reset, through the gear transmission system, the one-way gear 118 drives the rotating lead screw 119 to rotate. This rotation drives the connecting frame 114 and the moving plate 115 to move downward through the screw transmission, so that the connecting frame 114 always remains flush with the descending liquid level.

[0050] After completing the transfer and immersion of multiple pieces of nylon cloth and discharging the residual oily dye multiple times, the liquid level drops to the lowest height. At this time, water or the standby painting liquid needs to be replenished into the immersion tank 1 to restore the liquid level to the highest position. To ensure that the connecting frame 114 is flush with the latest liquid level, the staff can operate according to the following steps: manually pull up the one-way gear 118 to disengage it from the meshing state with the connecting rack 117. Rotate the one-way gear 118 in the reverse direction, and its function as a knob drives the rotating lead screw 119 to rotate in the reverse direction, and then drives the connecting frame 114 and the moving plate 115 to move upward through the screw transmission until they are flush with the latest liquid level. Finally, press the one-way gear 118 downward to re-engage it with the connecting rack 117 and restore the automatic adjustment function.

[0051] As Figure 2 As shown, symmetrically distributed baffles 101 are fixedly connected to the immersion tank 1 for restricting the position of the moving member 17 and ensuring its precise stop. When the moving frame 13 drives the moving member 17 to move leftward through the adsorption magnet 110, if the moving member 17 contacts the baffle 101, the baffle 101 plays a limiting role and prevents the moving member 17 from continuing to move leftward with the moving frame 13. As the moving frame 13 continues to move leftward, the magnetic connection between the two groups of adsorption magnets 110 will be disengaged, so that the moving member 17 can drive the first painting comb 15 or the second painting comb 16 to precisely stop at the initial position.

[0052] In this embodiment, the rotating lead screw 19 and the magnetic adsorption linkage structure are adopted to realize the automatic lifting and double-painting comb switching functions of the painting comb, and the seamless connection of the painting combs with different tooth pitches is completed through the cooperation of the connecting pull rope 18 and gravity, which not only simplifies the operation process but also ensures the pattern fineness and batch consistency; combined with the L-shaped scraper, the self-adjusting discharge window and the gear-rack transmission system, the automatic scraping of the residual dye on the liquid surface and the dynamic liquid surface tracking and cleaning are realized, effectively reducing manual intervention and material waste; the design of the closed cloth 113 and the moving plate 115 ensures the discharge sealing performance and avoids the leakage of the painting liquid; the baffle 101 limiting and magnetic adsorption disengagement mechanism precisely controls the reset of the moving member 17, and the self-locking function of the one-way gear 118 is used to improve the system stability, significantly improving the efficiency and quality of the nylon cloth wet transfer and immersion process.

[0053] Embodiment 2: In the wet painting process, if the painting comb only makes horizontal strokes, it is difficult to generate diverse patterns and cannot meet the requirements of pattern complexity and fineness. In addition, the single-direction stroke method limits the improvement of the dyeing effect of the nylon cloth. Therefore, a set of longitudinal stroke methods needs to be added to achieve a more colorful pattern effect and improve the quality of nylon cloth dyeing.

[0054] As Figures 7-9 shown, specifically, the dyeing tank 1 is slidably connected with a sliding frame 2, which slides along the longitudinal direction on the dyeing tank 1. The sliding frame 2 is also slidably connected with a third painting comb 27, which is used to make longitudinal strokes on the oily dye to generate unique patterns and moves longitudinally synchronously with the sliding frame 2.

[0055] When it is necessary to make forward and backward strokes on the dropped oily dye, the sliding frame 2 can be pushed to move forward longitudinally and then reset backward, so as to drive the third painting comb 27 to make reciprocating strokes on the liquid surface of the painting solution. This process can effectively guide the uniform diffusion of the oily dye and form a complex and unique pattern effect.

[0056] In the wet painting process, in order to meet the diversity and accuracy requirements of the strokes of the oily dye, when adding the new longitudinal stroke function, it is necessary to share the existing power source to avoid adding additional power devices, so as to reduce the system complexity and cost; while realizing the horizontal and longitudinal stroke functions, ensure that the strokes in both directions can work efficiently and collaboratively through the same set of power systems; ensure that the reciprocating movement of the third painting comb 27 on the longitudinal sliding frame 2 is accurately controllable and does not affect the normal operation of other components.

[0057] Specifically, a fixed block 22 is fixedly connected to the baffle 101. A guiding frame 21 is rotatably connected to the fixed block 22. A fixed gear 23 is fixedly connected to the guiding frame 21. A fixed rack 24 is fixedly connected to the top of the moving frame 13. The fixed gear 23 and the fixed rack 24 are meshed with each other, which also constitutes a gear transmission system for realizing the effective transmission and direction conversion of power; a rotating frame 25 is rotatably connected to the guiding frame 21, and a reset torsion spring 26 is connected between it and the guiding frame 21, which is used to automatically reset the rotating frame 25 after completing the action. The reset torsion spring 26 is wound around the guiding frame 21 to ensure that the rotating frame 25 can accurately reset and maintain the system stability; a chute is opened on the sliding frame 2, which is used to limit the movement track of the rotating frame 25 and ensure its stable operation. The rotating frame 25 is arranged in the chute of the sliding frame 2 and is used to drive the sliding frame 2 to move longitudinally through its own rotation; the distance between the rotating frame 25 and the moving part 17 is sufficient for the rotating frame 25 to rotate 90° to the left and reset, ensuring that the moving part 17 can smoothly cross the rotating frame 25 and complete the corresponding action.

[0058] When it is necessary to make a back-and-forth movement on the oil-based dye, the moving frame 13 is controlled to move leftward. Since the moving member 17 is blocked by the baffle 101, the moving frame 13 only drives the fixed rack 24 to move leftward. Through the gear transmission system, the fixed gear 23 rotates clockwise, driving the third painting comb 27 to rotate synchronously clockwise. At the same time, since the rotating frame 25 is stuck in the chute of the sliding frame 2, its clockwise rotation will push the sliding frame 2 forward, thus realizing the forward movement of the third painting comb 27.

[0059] When the moving frame 13 moves rightward, the fixed rack 24 moves rightward accordingly, and the fixed gear 23 rotates in the reverse direction, driving the guiding frame 21 to rotate counterclockwise. Through the linkage of the rotating frame 25, the sliding frame 2 and the third painting comb 27 move backward to reset, completing the back-and-forth movement of the third painting comb 27 on the painting liquid to produce the required pattern and enrich the pattern effect.

[0060] When the moving frame 13 pushes the moving member 17 to move left and right, if the moving member 17 contacts the rotating frame 25, the moving member 17 will resist the rotating frame 25, causing it to rotate upward by 90° around the guiding frame 21 to be flattened, so that the moving member 17 can smoothly cross over or avoid the rotating frame 25. At this time, the return torsion spring 26 is twisted and stores energy.

[0061] After the moving member 17 completely crosses over the rotating frame 25, under the elastic force of the return torsion spring 26, the rotating frame 25 automatically rotates downward by 90° to reset and return to the initial state, ensuring the normal operation of subsequent actions.

[0062] In this embodiment, by adding the longitudinal sliding frame 2 and the third painting comb 27, combining the gear-rack transmission and the linkage of the rotating frame 25, the original servo motor 11 power source is reused to achieve horizontal and longitudinal reciprocating movements, significantly improving the pattern complexity and fineness; the cooperation of the chute guiding of the rotating frame 25 and the return torsion spring 26 ensures the accurate longitudinal movement and automatic reset of the sliding frame 2. The avoidance design of the moving member 17 and the rotating frame 25 realizes seamless switching of multi-directional movements, avoids structural interference, expands functions without additional power, has a compact and reliable structure, reduces the transformation cost, meets the diverse dipping requirements, and improves the pattern layering and production efficiency of nylon cloth.

[0063] In the process of the existing painting comb moving the dye, the first painting comb 15, the second painting comb 16 and the third painting comb 27 only move along a straight line, resulting in a single texture of the drawn pattern and lacking rich changes. To solve this problem, a mechanism needs to be designed so that the painting comb can achieve the effect of swinging while moving during the movement, thereby drawing a wavy or other non-linear trajectory, significantly improving the texture richness and pattern diversity of the pattern.

[0064] Such as Figure 7 and Figure 8As shown in the figure, specifically, a first guiding frame 3 and a second guiding frame 31 are fixedly connected to the dipping tank 1, and both of them are provided with wavy sliding grooves for guiding the first painting comb 15 and the third painting comb 27 when they move, so that they can make small swings during the movement; a fixing member 32 is fixedly connected to one side of the first painting comb 15 close to the second guiding frame 31 and one side of the third painting comb 27 close to the first guiding frame 3, and a rotating rod 33 is provided on each fixing member 32. By adjusting the position of the rotating rod 33, the linear movement of the first painting comb 15 or the third painting comb 27 can be converted into a wavy or other non-linear trajectory sliding, thereby enriching the pattern texture.

[0065] When a pattern with richer texture needs to be made, the rotating rod 33 on the first painting comb 15 can be flipped forward by 270° so that it is embedded in the wavy sliding groove of the second guiding frame 31. At this time, when the moving member 17 drives the first painting comb 15 to move horizontally through the sliding rod 1501, since the rotating rod 33 is restricted by the trajectory of the wavy sliding groove, the first painting comb 15 will make small swings back and forth relative to the sliding rod 1501 while moving horizontally, thereby forming a wavy sliding trajectory and significantly improving the richness of the pattern.

[0066] Similarly, the rotating rod 33 on the third painting comb 27 is rotated 270° to the right so that it is embedded in the wavy sliding groove of the first guiding frame 3. When the sliding frame 2 drives the third painting comb 27 to move longitudinally, since the rotating rod 33 is restricted by the trajectory of the wavy sliding groove, the third painting comb 27 will make small swings left and right relative to the sliding frame 2 while moving longitudinally, thereby making the drawn pattern more textured and diverse. When it is necessary to switch to the linear mode, the rotating rod 33 can be rotated in the reverse direction to reset it so that it exits from the wavy sliding groove.

[0067] In this embodiment, by adding a linkage mechanism of a wavy sliding groove and a rotating rod 33, the linear movement of the painting comb is converted into a wavy swing trajectory, effectively breaking through the traditional linear sliding limit; using the original drive system to realize dynamic trajectory switching, greatly improving the pattern layering and artistic expressiveness; the adjustable angle design of the rotating rod 33 is compatible with the free switching between the linear / wavy modes, with a compact structure and convenient operation, significantly expanding the adaptability of the dipping process, reducing the production cost of complex textures, and enhancing the market competitiveness of nylon cloth products.
