Technical Field
[0001] This invention relates to the field of clothing technology, and in particular to a clothing dyeing apparatus. Background Technology
[0002] In the garment manufacturing process, dyeing is a crucial step in giving garments a variety of colors, directly affecting their appearance, color stability, and market competitiveness. With the rapid development of the garment industry, the market's requirements for the uniformity of dyeing, dyeing efficiency, dye utilization rate, and the integrity of finished garments are increasing.
[0003] Currently, most existing garment dyeing equipment uses a single stirring structure or static soaking method to achieve dyeing operations, which presents many problems that urgently need to be solved in practical applications:
[0004] Insufficient dyeing uniformity: Traditional dyeing equipment uses a relatively simple stirring method, mostly rotating and stirring in a fixed direction, which leads to uneven mixing of the dye liquor in the dyeing chamber and easy to cause local concentration differences. At the same time, the garment is prone to pile-up and tangling during the dyeing process, making it difficult for the dye liquor to fully contact the inside and between the fabrics, resulting in uneven dyeing depth and obvious color difference. This defect is more prominent for garments with special structures such as heavy fabrics and knitted fabrics.
[0005] Clothing is easily damaged and deformed: The clothing support structure of existing devices is mostly fixed, which is difficult to adapt to clothing of different sizes and styles. During support, it is easy to cause local compression or pulling of clothing. Moreover, when the mixing component comes into direct contact with clothing, the impact force is often too large or the contact method is improper, which often leads to wear and tear, pilling, or even damage and deformation of clothing fabric, affecting the quality of finished clothing.
[0006] Low dye utilization: During the dyeing process, dyes tend to deposit at the bottom of the dyeing chamber due to gravity. Existing circulation systems are mostly simple extraction structures, which cannot achieve efficient circulation and uniform distribution of dye liquor. This not only wastes dye and increases production costs, but also increases the difficulty of subsequent cleaning due to dye deposition, resulting in greater environmental pressure.
[0007] Limited stirring effect: Traditional stirring components have a fixed movement pattern and can only achieve stirring in one dimension. The relative movement intensity between the dye liquor and the clothing fabric is insufficient, making it difficult for the dye liquor to fully penetrate into the fabric fibers, resulting in prolonged dyeing time and low production efficiency. At the same time, some devices lack dynamic adjustment of the dye liquor flow direction, which further reduces the sufficiency of dyeing.
[0008] Poor operational flexibility: The existing equipment has an unreasonable design for garment hanging, lifting, and position adjustment structures, which makes it impossible to flexibly adjust the soaking depth and posture of the garments according to the dyeing process. In addition, the batch size for a single dyeing operation is limited, making it difficult to adapt to the needs of large-scale production. Furthermore, the inconvenience of adjusting the support structure also results in poor compatibility of the equipment with different sizes of garments, limiting its applicability.
[0009] In view of the shortcomings of the existing technology, there is an urgent need for a garment dyeing device that can achieve uniform mixing of dye liquor, full dyeing of garments, reduced fabric damage, and improved dye utilization, so as to meet the high quality and high efficiency requirements of garment production and promote the optimization and upgrading of the dyeing process.

[0019] Preferably, the surface of the stirring paddle is provided with several through holes, the diameter of which is 1-3 mm.
[0020] Preferably, the surface of the garment support rod is covered with an anti-slip rubber layer, the thickness of which is 0.5-1mm.
[0021] The beneficial effects of the present invention are as follows: (1) The dyeing uniformity is significantly improved: Through the synergistic effect of multi-dimensional stirring and the dynamic adjustment structure of the garment, the problem of uneven dyeing depth in traditional dyeing is completely solved. In the rotating stirring component, the rotating shaft drives the cover and the rolling roller to revolve, while the reciprocating motion component drives the rack to move back and forth. Through gear meshing, the rotating rod and the stirring paddle rotate alternately in opposite directions. With the 1-3mm through holes on the surface of the stirring paddle, the dye liquor is mixed in a three-dimensional manner. The turntable drives the garment to rotate at a uniform speed under the drive of the second motor. The lifting component can flexibly adjust the soaking depth of the garment to avoid the fabric from accumulating and tangling. In addition, the diversion and guiding effect of the grid (2-5mm mesh) ensures that the dye liquor is fully contacted inside and outside the garment fabric and between the fabrics. Even for heavy, knitted and other special structure garments, uniform dyeing can be achieved throughout the entire area, and the color difference is significantly reduced.
[0022] (2) The integrity of the garment is fully protected: In view of the defects of existing devices that are prone to damaging the fabric, the design of the support and contact structure has been optimized. The surface of the garment support rod is covered with a 0.5-1mm anti-slip rubber layer, which not only enhances the support stability, but also avoids direct friction damage to the fabric; the garment support component is driven by a fourth motor to rotate the shaft, and the positive and negative spiral threads drive the relative movement of the moving plate. The opening angle of the support rod can be adjusted by the connecting rod, which can accurately adapt to different sizes and styles of garments and avoid deformation caused by local compression or pulling; the pressing roller adopts a movable connection design, which gently presses the garment to assist in dyeing without hard impact, effectively preventing fabric wear, pilling or damage, and ensuring the quality of the finished garment.
[0023] (3) The utilization rate of dyes is greatly improved, and the environmental pressure is reduced: The structure of the circulation system is optimized to solve the problem of dye deposition and waste. The tapered tube at the bottom of the lower dyeing chamber can efficiently collect the deposited dyes. The pump pumps the bottom dye liquor to the upper end for recycling through the connecting pipe, forming a closed loop circulation, reducing the waste of dyes caused by deposition and reducing production costs. At the same time, the full circulation of dye liquor reduces the amount of residual dyes, reduces the difficulty of subsequent cleaning, reduces the pressure of wastewater treatment, and is more in line with environmental protection requirements.
[0024] (4) Upgraded stirring efficiency and shortened dyeing cycle: Breaking through the limitations of traditional single-dimensional stirring, a multi-form synergistic stirring system is constructed. The rotating stirring component integrates the triple functions of revolution, reciprocating rotation of the stirring paddle, and pressing of the rolling roller, which not only enhances the flow intensity of the dye liquor, but also breaks the dye liquor boundary layer on the fabric surface, promoting the penetration of the dye liquor into the fiber interior; the through-hole design of the stirring paddle can reduce stirring resistance and increase the dye liquor circulation speed. Compared with the traditional static soaking or single stirring method, the dyeing time is significantly shortened and the production efficiency is greatly improved.
[0025] (5) Enhanced operational flexibility and compatibility, adapting to large-scale production: Optimized garment hanging and adjustment structure, improving the applicability and production volume of the device. 4-6 lifting components are evenly distributed on the lower surface of the turntable, allowing multiple garments to be dyed at once, meeting the needs of large-scale production; the lifting components precisely adjust the garment height through screw transmission, and dynamically adjust the garment posture in conjunction with the turntable rotation, allowing for flexible optimization of the soaking state according to the dyeing process; the adjustable design of the garment support components enables the device to adapt to different specifications and styles of garments, with strong compatibility and reduced equipment replacement costs.
[0026] (6) Stable and durable structure with long service life: Key components are made of high-quality materials and have a reasonable structural design to ensure long-term stable operation of the device. The grid is made of corrosion-resistant metal material, which can withstand the erosion of dye liquid and extend its service life; all rotating parts are connected by bearings, and with the sliding structure such as moving wheels and sliders, mechanical wear is reduced and the operational stability is improved; the buffer design of components such as springs and pneumatic cylinders reduces mechanical impact, further ensuring the durability of the overall structure of the device and reducing maintenance costs.
[0027] (7) Optimized operating energy consumption and enhanced practicality: While multiple components work together, energy consumption is also controlled. The through-hole design of the stirring paddle and the efficient reflux structure of the circulation system reduce the load on power components such as motors and liquid pumps, thus reducing energy consumption; the high degree of integration of each component of the device and the simple operation process eliminate the need for complex manual intervention, thereby reducing labor intensity and human error, and improving the stability and practicality of the dyeing process.

Detailed Implementation
[0039] like Figures 1 to 3As shown, this specific embodiment adopts the following technical solution: a garment dyeing device, including a lower dyeing chamber 1, an upper dyeing chamber 2, a circulation component, an opening 7, a cylinder 8, a grid 9, a rotating agitator component, a bearing 11, a first gear 28, a first motor 29, a second gear 30, a second motor 31, a third gear 32, a T-shaped rotating shaft 33, a fourth gear 34, a turntable 35, a lifting component, and a garment support component; wherein, the lower dyeing chamber 1 and the upper dyeing chamber 2 are fixedly connected to form a closed dyeing space, the lower dyeing chamber 1 is used to store dye liquor, and the upper dyeing chamber 2 provides an installation carrier for the power component and the adjustment component; the circulation component set at the lower end and side of the lower dyeing chamber 1 can realize the closed-loop circulation of dye liquor and avoid dye deposition; the opening 7 at the center of the upper end of the lower dyeing chamber 1 facilitates the entry and exit of garments from the dyeing area, the cylinder 8 fixed at the upper end of the chamber provides a limited space for garment dyeing, and the grid 9 on both sides of the cylinder 8 has a mesh diameter of 2-5mm and is made of corrosion-resistant metal material, which can play a diversion and guiding role for the dye liquor and improve the uniformity of dye liquor flow. A rotating agitator is movably connected to both sides of the lower dyeing chamber 1 and the upper dyeing chamber 2 via bearings 11, which is used to achieve multi-dimensional stirring of the dye liquor. The first gear 28 at the top of the rotating agitator meshes with the second gear 30 at the output end of the first motor 29 at the middle of the upper surface of the upper dyeing chamber 2, and the first motor 29 drives the rotating agitator to revolve. A T-shaped rotating shaft 33 is movably connected to the top of the upper dyeing chamber 2. The fourth gear 34 at the outer end of the shaft meshes with the third gear 32 at the output end of the second motor 31. After the second motor 31 is started, it can drive the turntable 35 at the end of the T-shaped rotating shaft 33 to rotate at a constant speed. 4-6 lifting components are evenly distributed in a circular array on the lower surface of the turntable 35. The garment support components connected to the movable ends of the lifting components are used to fix and support the garment. Through the coordinated action of the lifting components and the turntable 35, the soaking depth and posture of the garment can be dynamically adjusted.
[0040] like Figures 4 to 7As shown, the rotary agitation assembly includes a rotary shaft 10, a cover 12, a pressing roller 13, a rotating rod 14, a stirring paddle 15, a rack 23, a gear 24, and a reciprocating motion assembly. The rotary shaft 10 is movably connected between the lower dyeing chamber 1 and the upper dyeing chamber 2 via a bearing 11, serving as the core support structure of the rotary agitation assembly. The cover 12, fixed at the end of the rotary shaft 10, provides installation protection for the pressing roller 13. Two mutually spaced pressing rollers 13 are movably connected at the lower end of the cover 12, which gently press the garment during the revolution of the rotary shaft 10, assisting in the penetration of the dye liquor, without any hard impact, thus avoiding damage to the fabric. The lower end of the rotating shaft 10 is movably connected to the rotating rod 14 via the bearing 11. The stirring paddle 15 fixed at both ends of the rotating shaft 10 has through holes with a diameter of 1-3mm on its surface, which can reduce stirring resistance and improve the mixing effect of the dye liquor. The gear 24 at the middle end of the rotating rod 14 meshes with the rack 23 at the output end of the reciprocating motion component. The reciprocating motion component fixed at the upper end of the rotating shaft 10 drives the rack 23 to move back and forth. Through the meshing transmission of the gear 24 and the rack 23, the rotating rod 14 and the stirring paddle 15 are driven to rotate alternately in the forward and reverse directions. In conjunction with the revolution of the rotating shaft 10, the three-dimensional stirring of the dye liquor is realized.
[0041] like Figures 4 to 7 As shown, the reciprocating motion assembly includes a groove 16, a slider 17, a moving wheel 18, a slide rod 19, a mounting block 20, a limiting block 21, a spring 22, a pneumatic cylinder 25, a pull rope 26, and a roller 27. The grooves 16 on both sides of the upper end of the chamber of the rotating shaft 10 provide a sliding track for the moving wheel 18, and the roller 27 is used to change the direction of force on the pull rope 26. The pneumatic cylinder 25 fixed at the top of the chamber of the rotating shaft 10 provides power for the reciprocating motion, and the pull rope 26 fixed at its output end passes through the roller 27 and then interacts with the slider. 17 is fixedly connected; the movable wheels 18 on both sides of the slider 17 are slidably connected in the groove 16 to ensure that the slider 17 moves smoothly; the slide rod 19 fixed at the end of the slider 17 passes through the mounting block 20 and is fixed to the rack 23, and the mounting block 20 plays a guiding and supporting role for the slide rod 19; the spring 22 between the limiting block 21 at the middle end of the slide rod 19 and the mounting block 20 realizes the reset of the slide rod 19 when the pneumatic cylinder 25 contracts, thereby driving the rack 23 to reciprocate, and finally realizes the alternating forward and reverse rotation of the stirring paddle 15.
[0042] like Figure 8As shown, the lifting assembly includes a lifting assembly housing 36, a third motor 37, a first bearing seat 38, a lead screw 39, and a lifting block 40. The lifting assembly housing 36 is fixedly connected to the lower surface of the turntable 35, providing protection and installation space for the internal components. The third motor 37 at the upper end of the chamber of the lifting assembly housing 36 provides power for the lifting action, and the first bearing seat 38 at the lower end supports the lead screw 39 to ensure stable rotation of the lead screw 39. One end of the lead screw 39 is fixed to the output end of the third motor 37, and the other end is movably connected to the first bearing seat 38. The lifting block 40 is slidably connected inside the lifting assembly housing 36, and its middle end is connected to the lead screw 39 by a thread. After the third motor 37 is started, it drives the lead screw 39 to rotate forward and backward, and through the threaded transmission, it drives the lifting block 40 to slide up and down along the lifting assembly housing 36, thereby adjusting the height of the garment support assembly and realizing flexible control of the garment soaking depth.
[0043] like Figures 9 to 10 As shown, the garment support assembly includes a garment support assembly housing 41, a fourth motor 42, a rotating shaft 43, a forward spiral thread 44, a reverse spiral thread 45, a first movable plate 46, a second movable plate 47, a first connecting rod 48, a second connecting rod 49, a connecting block 50, a garment support rod 51, and a second bearing seat 52. The garment support assembly housing 41 is fixed to the side of the lifting block 40, and the fourth motor 42 at the top provides power for adjusting the support structure. The second bearing seat 52 at the top and bottom of the garment support assembly housing 41 supports the rotating shaft 43. The rotating shaft 43 is fixedly connected to the output end of the fourth motor 42, and its two ends are forward spiral threads 44, reverse spiral threads 45, first movable plate 46, second movable plate 47, first connecting rod 48, second connecting rod 49, connecting block 50, garment support rod 51, and second bearing seat 52. The spiral thread 44 and the reverse spiral thread 45 are threadedly connected to the first moving plate 46 and the second moving plate 47, respectively. When the fourth motor 42 drives the rotating shaft 43 to rotate, the spiral thread 44 and the reverse spiral thread 45 drive the first moving plate 46 and the second moving plate 47 to move relative to or in opposite directions. In turn, the first connecting rod 48 and the second connecting rod 49, which are hinged on both sides, push the connecting block 50 to move, so as to open or close the garment support rod 51 to adapt to different sizes and styles of garments. The surface of the garment support rod 51 is covered with a 0.5-1mm thick anti-slip rubber layer, which not only enhances the stability of garment support, but also avoids direct friction damage to the fabric.
[0044] like Figure 2 As shown, the circulation assembly includes a pump 3, an outlet hole 4, a tapered tube 5, and a connecting tube 6. The pumps 3 on the left and right sides of the lower dyeing chamber 1 provide power for the dye liquor circulation. The outlet holes 4 on both sides of the lower end of the lower dyeing chamber 1 facilitate the flow of dye liquor from the bottom. The tapered tubes 5 fixed on both sides of the lower surface are located directly below the outlet holes 4, which can efficiently collect the deposited dye. The input end of the pump 3 is connected to the tapered tube 5 through the connecting tube 6, and the output end is connected to the upper end of the lower dyeing chamber 1 through the connecting tube 6. After the pump 3 is started, the dye liquor containing deposited dye at the bottom of the lower dyeing chamber 1 can be pumped to the upper end to form a closed loop circulation, improve the dye utilization rate, and reduce waste and environmental pressure.
[0045] The grille 9 is made of corrosion-resistant metal and has a mesh size of 2-5mm. The number of lifting components fixedly connected to the lower surface of the turntable 35 is 4-6 and they are evenly distributed along the center of the turntable 35. The surface of the stirring paddle 15 is provided with several through holes with a diameter of 1-3mm. The surface of the clothing support rod 51 is covered with an anti-slip rubber layer with a thickness of 0.5-1mm.
[0046] The usage of this invention is as follows: Before use, a comprehensive inspection of the device is conducted to confirm that the sealing performance of the lower dyeing chamber 1 and the upper dyeing chamber 2 is good, that the liquid pump 3 and the connecting pipe 6 of the circulation component are not blocked or leaking, that all transmission components such as bearings 11, gears 24, and the first gear 28 are adequately lubricated, and that the first motor 29, the second motor 31, the third motor 37, the fourth motor 42, and the pneumatic cylinder 25 are operating normally. Then, according to the size and style of the garment to be dyed, the fourth motor 42 is started, and its output end drives the rotating shaft 43 to rotate. Using the forward thread 44 and the reverse thread 45 at both ends of the rotating shaft 43, the first moving plate 46 and the second moving plate 47 are driven to move closer or further apart. Through the first connecting rod 48 and the second connecting rod 49, the connecting block 50 is pushed to move, so that the garment support rod 51 opens to the appropriate angle. Using the 0.5-1mm thick anti-slip rubber layer on the surface of the support rod, the garment to be dyed is stably fixed on the garment support rod 51 to prevent the garment from slipping or unevenly stressed in some areas.
[0047] During the dyeing preparation stage, the third motor 37 is started, and its output end drives the lead screw 39 to rotate in the first bearing seat 38. Through the threaded transmission, the lifting block 40 slides down along the lifting component cover 36, driving the garment support component and the fixed garment through the opening 7 at the upper end of the lower dyeing chamber 1 and into the cylinder 8. According to the dyeing process requirements, the soaking depth of the garment can be precisely adjusted in real time by the forward and reverse rotation of the third motor 37 to ensure that the garment is completely immersed in the dye solution or reaches the preset soaking height. Then, the third motor 37 is turned off.
[0048] During the dyeing process, a pre-concentrated dye solution is injected into the dye tank 8, with the amount of dye solution sufficient to cover the garment without overflowing. Simultaneously, the first motor 29, the second motor 31, and the pump 3 are started: the first motor 29 drives the second gear 30 to rotate, which, through meshing with the first gear 28, drives the rotating shaft 10 to revolve around the bearing 11, thereby driving the housing 12 and the internal pressing roller 13 and stirring paddle 15 to revolve. During this rotation, the pressing roller 13 gently presses the garment, aiding in dye penetration. Simultaneously, the pneumatic cylinder 25 inside the rotating shaft 10 is activated, pulling the slider 17 via the pull rope 26. Combined with the resetting action of the spring 22, this drives the slide rod 19 to move the rack 23 back and forth along the groove 16. The rack 23 meshes with the gear 24, causing the rotating rod 14 and stirring paddle 15 to rotate alternately in both directions. The 1-3mm through holes on the surface of the stirring paddle 15 reduce stirring resistance and achieve three-dimensional mixing of the dye liquor; the second motor 31 drives the third gear 32 to rotate, and through the meshing transmission with the fourth gear 34, drives the T-shaped rotating shaft 33 and the turntable 35 to rotate at a uniform speed. The 4-6 lifting components evenly distributed on the lower surface of the turntable 35 synchronously drive the garment to rotate, avoiding the accumulation and entanglement of the fabric; the liquid pump 3 pumps the dye liquor containing deposited dye collected at the bottom of the lower dyeing chamber 1 through the tapered pipe 5 to the upper end of the lower dyeing chamber 1 through the connecting pipe 6, forming a closed loop circulation. The grid 9 with 2-5mm mesh on both sides of the cylinder 8 plays a diversion and guiding role for the circulating dye liquor, ensuring that the dye liquor is fully in contact with the inside and outside of the garment fabric and between the fabrics.
[0049] During the dyeing process, the height of the lifting component can be adjusted by the third motor 37 to change the immersion depth of the garment, or the speed of the first motor 29 and the second motor 31 can be adjusted to optimize the stirring intensity and the rotation speed of the garment, so as to ensure that even heavy, knitted and other special-structure garments can be dyed evenly throughout.
[0050] After dyeing is completed, first turn off the first motor 29, the second motor 31 and the liquid pump 3 to stop the stirring and circulation. Then start the third motor 37 in reverse to drive the lifting block 40 to move the garment support assembly and the dyed garment upwards, and move them out of the cylinder 8 through the opening 7 to the preset position.
