Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing and dyeing, and in particular to a high-efficiency dyeing mechanism. Background Technology
[0002] Fabric dyeing is a crucial step in textile processing, and its uniformity, penetration, and colorfastness directly affect the quality and market competitiveness of the final product. In existing technologies, common fabric dyeing equipment mainly employs fixed clamping or roll-to-roll conveying structures, immersing the fabric in a dyeing tank. However, traditional structures have the following prominent problems:
[0003] First, during the dyeing process, most fabrics are in a static or unidirectional tension state, making it difficult to open the fiber gaps. This leads to uneven dye penetration, easily resulting in defects such as localized light or dark dyeing, or color spots and color differences. It is especially difficult to ensure dyeing consistency when dealing with fabrics with complex structures or high elasticity.
[0004] Secondly, due to the limited dyeing depth, some dyes only adhere to the fiber surface and fail to penetrate the interior, which can easily lead to fading and discoloration after dyeing, affecting color fastness, especially under actual use conditions such as washing and rubbing. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an efficient dyeing mechanism that solves the problems of uneven dyeing and easy fading in traditional dyeing mechanisms.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A high-efficiency dyeing mechanism for dyeing fabrics, including a turntable assembly and a stretching assembly;
[0008] The turntable assembly includes a first driving component, a floating disk, and a driving disk; the first driving component is drivenly connected to the driving disk and is used to control the rotation of the driving disk; the driving disk and the floating disk are coaxially drivenly connected.
[0009] The stretching assembly includes two clamping plates arranged opposite each other, with the fabric passing through the two clamping plates; the two clamping plates are perpendicularly connected to the end face of the floating disk.
[0010] In some embodiments, the floating disk is provided with transmission slots, the number of which is at least two and is evenly distributed along the circumference of the floating disk; the drive disk is provided with transmission rods, the number of which matches the number of transmission slots; the transmission rods are connected to the end face of the drive disk near the floating disk and pass through the transmission slots.

[0024] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0025] Please refer to Figures 1 to 4 A high-efficiency dyeing mechanism for dyeing fabric 3, comprising a turntable assembly 1 and a stretching assembly 2;
[0026] The turntable assembly 1 includes a first driving element 11, a floating disk 12, and a driving disk 13; the first driving element 11 is connected to the driving disk 13 and is used to control the rotation of the driving disk 13; the driving disk 13 and the floating disk 12 are connected coaxially.
[0027] The stretching assembly 2 includes two clamping plates 21 arranged opposite to each other, and the fabric 3 is passed between the two clamping plates 21; the two clamping plates 21 are perpendicularly connected to the end face of the floating disk 12.
[0028] As described above, by combining the turntable assembly 1 and the stretching assembly 2, the fabric 3 is subjected to rotation and stretching during the dyeing process, thereby effectively improving the dyeing uniformity and penetration efficiency of the fabric 3. Specifically, the drive disk 13 in the turntable assembly 1 is driven to rotate by the first drive component 11, causing the floating disk 12, which is coaxially connected to it, to rotate synchronously. This causes the clamping plate 21 on the floating disk 12 to rotate accordingly. The clamping plate 21 holds the fabric 3, forming a relatively stretched motion trajectory during rotation. This effectively unfolds the fiber structure of the fabric 3, increases its surface area, and helps the dye liquor penetrate more fully into the fibers, improving dyeing depth and color fastness. Compared to traditional static clamping dyeing methods, this mechanism can dynamically adjust the posture and stress state of the fabric 3 in the dye liquor, thereby reducing problems such as color spots and color differences.
[0029] Preferably, the first drive unit controls the drive disk 13 to perform bidirectional reciprocating rotation, thereby controlling the clamping plate 21 to swing continuously in two opposite directions, achieving the effect of unfolding the fibers of the fabric 3.
[0030] In some embodiments, the floating disk 12 is provided with transmission slots 121, the number of which is at least two and is evenly distributed along the circumference of the floating disk 12; the driving disk 13 is provided with transmission rods 131, the number of which matches the number of transmission slots 121; the transmission rods 131 are connected to the end face of the driving disk 13 near the floating disk 12 and pass through the transmission slots 121.
[0031] As described above, by setting multiple circumferentially distributed transmission slots 121 on the floating disk 12 and setting a matching number of transmission rods 131 on the drive disk 13, a flexible connection and synchronous transmission between the drive disk 13 and the floating disk 12 are achieved. This structure ensures effective driving of the floating disk 12 by the drive disk 13, and by introducing a floating structure, it reduces sudden impact forces during the driving process, thereby avoiding damage caused by directly pulling the fabric 3. This floating connection mechanism can absorb some of the energy fluctuations during the rotation or tension change of the fabric 3, thus protecting the integrity of the fabric 3 fibers and extending the equipment life. In addition, the transmission rods 131 pass through the slots of the floating disk 12 to form a groove-like fit, which has a certain tolerance adjustment capability and is suitable for fabrics 3 of different thicknesses and elastic coefficients, enhancing the versatility of the device.
[0032] In some embodiments, the turntable assembly 1 further includes a drive shaft 14 and a reset member 15. The first drive member 11 is connected to the drive disk 13 via the drive shaft 14, and the drive shaft 14 is movably connected to the floating disk 12. The reset member 15 is movably connected to the drive shaft 14 and is used to assist the floating disk 12 in resetting.
[0033] As described above, the introduction of the combined structure of the drive shaft 14 and the reset component 15 further optimizes the motion control mechanism of the floating disk 12. The drive shaft 14 connects the first drive component 11 to the drive disk 13, achieving stable and reliable power transmission. The drive shaft 14 and the floating disk 12 are connected movably, granting the floating disk 12 a certain degree of freedom. When the drive stops or needs to return to its initial position, the reset component 15 applies a reverse force to the floating disk 12, assisting it in returning to its initial angle or initial tension state. This design not only avoids the problem of the floating disk 12 continuing to rotate due to inertia after stopping, causing the fabric 3 to become entangled, but also provides higher control accuracy. The movable connection also allows the floating disk 12 to deflect within a certain range when subjected to accidental impacts, effectively absorbing excess energy and preventing damage to the internal structure or the fabric 3, further enhancing the stability and anti-interference capability of the device. This structure is particularly suitable for dyeing conditions with frequent changes in dynamic load, helping to improve the reliability of equipment operation and the consistency of dyeing quality.
[0034] In some embodiments, the reset member 15 includes a torsion spring 151 and an abutment plate 152. The torsion spring 151 is sleeved on the transmission shaft 14 and movably connected to the transmission shaft 14. The abutment plate 152 is fixedly connected to the end face of the floating disk 12 near the drive disk 13. When the abutment plate 152 abuts against the torsion spring 151, it assists the floating disk 12 in resetting.
[0035] As described above, the structure of the reset component 15 is specified. Through the combination of the torsion spring 151 and the abutment plate 152, an elastic system with self-resetting capability is constructed. The torsion spring 151, acting as an energy storage element, undergoes elastic deformation during the rotation of the floating disk 12 driven by the drive shaft 14. After rotation stops, it releases elastic energy, pushing the abutment plate 152 to return the floating disk 12 to its initial position. The abutment plate 152 ensures the stable transmission of the force from the torsion spring 151, and its fixed connection with the floating disk 12 further enhances the reset accuracy. This structure not only boasts advantages in structural compactness but is also easy to adjust and maintain, making it suitable for dyeing various fabric materials.
[0036] In some embodiments, the stretching assembly 2 further includes a second drive member 22, which is tractively connected to the two clamping plates 21 and is used to control the two clamping plates 21 to move closer to or further away from each other.
[0037] As described above, the dynamic clamping control of the fabric 3 is achieved by controlling the approach or distance of the two clamping plates 21 through the second driving component 22. Compared with the traditional fixed clamping method, this structure can flexibly adjust the clamping force and spacing according to the type, thickness, or dyeing process requirements of the fabric 3, thereby improving dyeing adaptability. Especially when dealing with elastic fabrics or multi-layered fabrics 3, it can effectively avoid the problem of fabric 3 deformation due to excessive clamping force or positional displacement due to loose clamping. In addition, the programmable control of the clamping plate 21 through the driving component, combined with steps such as dye injection, preheating, and rotation, can realize automatic cycle control of the integrated dyeing process, reduce manual intervention and the probability of misoperation, and significantly improve the automation level and production efficiency of the dyeing equipment.
[0038] In some embodiments, the end face of the clamp 21 that abuts against the fabric 3 is provided with an atomizing nozzle 211, and the atomizing nozzle 211 is connected to the dyeing liquid pipeline.
[0039] As described above, by setting an atomizing nozzle 211 at the contact end of the clamping plate 21 with the fabric 3 and connecting it to the dye liquor pipeline, the dye liquor can be finely atomized and sprayed onto the surface of the fabric 3 while being clamped. Compared with immersion dyeing, this atomization method has advantages in energy and liquor saving, effectively controls the amount of dye used, and promotes the penetration and diffusion of the dye liquor in the fibers of the fabric 3. It is particularly suitable for multi-layer spray dyeing or multi-color zone dyeing processes. While maintaining the controlled state of the fabric 3, the spray dyeing is completed, effectively improving the local coloring accuracy and overall dyeing uniformity. With the rotational movement of the clamping plate 21, the atomized dye liquor coverage is more uniform, solving the color difference problem caused by the tension or unstable position of the fabric 3 in the traditional spray dyeing process.
[0040] In some embodiments, the clamping plate 21 is provided with a heating module.
[0041] As described above, the heating module located inside the clamping plate 21 can heat the fabric 3 during the dyeing process, enhancing dye activation and accelerating the dyeing rate. The heat causes the fiber micropores to open, making it easier to adsorb dye molecules, thereby increasing dyeing depth and dye fixation rate. Furthermore, the heating process can also be used for setting, making it particularly suitable for dyeing and finishing processes of synthetic fibers or heat-sensitive fabrics. Compared to external large-area heating, this heating module performs heat treatment locally during clamping, significantly reducing energy consumption, improving heating efficiency, and lowering the size and power consumption requirements of the equipment, making it suitable for energy-efficient production systems.
[0042] In some embodiments, the two clamps 21 are corrugated clamps 21 that match each other.
[0043] As described above, by employing corrugated clamps 21 that match each other, the contact area of the fabric 3 is increased, forming a multi-point contact stretching structure, thus avoiding stress concentration or slippage of the fabric 3 caused by linear clamping. Simultaneously, the corrugated structure can form micro-cavities, which is beneficial for the accumulation and slow release of dye or atomized particles, thereby improving dyeing uniformity. For fabrics 3 with textured or three-dimensional structures, the corrugated clamps 21 can better conform to their surface shape, achieving more stable fixation and deeper dyeing, making them particularly suitable for the precise dyeing needs of irregularly shaped and elastic fabrics.
[0044] The embodiments of this utility model are as follows:
[0045] A high-efficiency dyeing mechanism is used for continuous, uniform, and energy-saving dyeing of fabric 3. It mainly comprises two modules: a turntable assembly 1 and a stretching assembly 2. The turntable assembly 1 includes a first drive component 11, a drive disk 13, a floating disk 12, a transmission shaft 14, and a reset component 15. The stretching assembly 2 includes two opposing clamping plates 21, a second drive component 22, an atomizing nozzle 211, and a heating module. The entire mechanism, through a multi-structure linkage design, achieves various effects such as dynamic tensioning of the fabric 3 under the action of dye liquor, uniform dyeing, and intelligent control.
[0046] In terms of specific structure, the first driving component 11 is mounted on one side of the frame to provide power output. Its output end is connected to the driving disk 13 via a drive shaft 14. The driving disk 13, through multiple drive rods 131 set on its end face, engages with the drive holes and slots 121 on the floating disk 12 to achieve synchronous and flexible driving connection to the floating disk 12. The drive holes and slots 121 are evenly distributed around the circumference of the floating disk 12, and the drive rods 131 pass through them. During rotation, they can both drive the floating disk 12 to rotate and allow the floating disk 12 to deflect a certain amount relative to the driving disk 13, absorbing impact force and releasing tension fluctuations in the fabric 3.
[0047] Two clamping plates 21 are fixedly connected to the end face of the floating disk 12. The clamping plates 21 are arranged opposite each other to clamp the fabric 3 to be dyed. The clamping plates 21 are corrugated in shape and cooperate with each other to form a multi-point contact nonlinear clamping interface, which increases the contact area and realizes stable stretching of the fabric 3 during rotation, avoiding problems such as slippage or uneven dyeing at the edges caused by linear clamping. The clamping plates 21 are controlled by the second driving member 22, and their movement direction is perpendicular to the plane of the fabric 3. The clamping force can be adjusted according to the thickness or type of the fabric 3, and the clamping plates 21 can automatically open and close.
[0048] During the dyeing process, the first driving component 11 controls the bidirectional reciprocating rotation of the driving disk 13 and the floating disk 12. The two clamping plates 21 holding the fabric 3 rotate around the central axis with the floating disk 12, enabling the fabric 3 to be continuously stretched and oscillated in the dye bath, significantly improving the penetration efficiency of the dye bath into the fibers of the fabric 3. At the same time, the atomizing nozzles 211 on the clamping plates 21 are connected to the dye bath pipeline to uniformly spray high-concentration dye bath in the form of micro-mist onto the surface of the fabric 3. As the fabric 3 oscillates continuously, a cross-spraying effect is formed, solving the problems of local accumulation and color difference. In addition, the clamping plates 21 are also equipped with a local heating module, which heats the fabric 3 during the spray dyeing process, allowing the fiber molecules to fully open, improving the dye binding rate, and taking into account the requirements of fabric 3 for setting and quick drying, making it suitable for high-fastness and fast-reaction dyeing and finishing processes.
[0049] During operation, as the floating disc 12 rotates under drive, a certain range of sliding is allowed between the transmission slot 121 and the transmission rod 131, which can automatically adjust the angular deviation of the fabric 3 under different tension states, thus playing a buffering role. When the drive stops or the fabric needs to be changed, the torsion spring 151 on the transmission shaft 14 performs its energy storage function, applying a reverse force to the abutment plate 152 connected to the floating disc 12, causing the floating disc 12 to automatically rotate back to its initial position, completing the reset of the clamping plate 21, which facilitates the re-clamping of new fabric 3 or the entry into the next cycle. This structure can significantly reduce manual intervention, reduce the risk of fabric 3 entanglement, and improve the stability of the operation cycle.
[0050] In summary, this utility model provides a high-efficiency dyeing mechanism that achieves dynamic stretching and rotation of fabric in the dye liquor through the coordinated operation of the turntable assembly and the stretching assembly, thereby improving dyeing uniformity and penetration efficiency. A flexible transmission structure is used between the drive disc and the floating disc to avoid fabric damage caused by rigid impacts and adapt to different tension states. The clamping plate has a corrugated structure and is adjusted via a second drive component, effectively unfolding the fabric fibers and adapting to various fabric types. The clamping plate is equipped with atomizing nozzles and a heating module, which can simultaneously complete dye liquor spraying and heating during rotation and stretching, improving dye adsorption rate and adhesion fastness, and achieving energy efficiency. The torsion spring reset mechanism automatically restores the clamping plate position when not in operation, facilitating cyclic operation. The overall structure is compact, the control is precise, and the adaptability is strong, making it suitable for continuous dyeing and finishing of various types of fabrics and possessing significant industrial application value.
