Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing technology, and in particular to a fabric color-developing machine. Background Technology

[0002] In modern textile processing technology, digital direct-to-garment printing has been widely used in various fields such as footwear materials and clothing fabrics due to its advantages such as no need for plate making, high pattern precision, and rich color expression. To improve the color saturation of the printed pattern and the adhesion of the ink to the fabric, high-temperature heating is usually required after printing for color development and fixing. This color development process generally needs to be carried out at a high temperature of 190℃ to 250℃ for several minutes to allow the dye in the ink to fully combine with the fibers. However, under high-temperature conditions, different fabric materials (especially polyester or mesh fabrics) are prone to thermal shrinkage, leading to fabric dimensional deformation and pattern position shift, seriously affecting the precision of the printed pattern and the consistency of the finished product's width.

[0003] Existing fabric coloring devices mostly use guide belts or tensioning structures to pull the fabric through the coloring area and use the fabric's own weight or tensioning devices at both ends of the fabric to initially flatten the fabric surface. However, due to the lack of effective control over the edges of the fabric, especially during the heat shrinkage process, they cannot dynamically adapt to changes in the fabric width, which can easily cause fabric wrinkles, local tearing, or pattern misalignment. Utility Model Content

[0025] 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.

[0026] Please refer to Figures 1 to 4 A fabric 3 coloring machine is used to color fabric 3 using high temperature, including a track assembly 1 and a hanging shaft assembly 2;

[0027] The track assembly 1 includes a pin plate 11, a track 12, and an adjusting member 13; the pin plate 11 is connected to the adjusting member 13, the adjusting member 13 is movably connected to the track 12 and symmetrically arranged at both ends of the track 12 in the width direction, and the adjusting member 13 is used to adjust the spacing between the two pin plates 11 in the width direction of the track 12.

[0028] As can be seen from the above description, the beneficial effects of this utility model are as follows: by setting adjustment parts 13 at both ends of the track 12 and cooperating with the hanging shaft assembly 2 to control the travel direction of the track 12, the distance between the needle plates 11 can be dynamically adjusted according to the thermal expansion and contraction of the fabric 3 during the color development process, thereby ensuring that both sides of the fabric 3 are always in a suitable tension state, effectively preventing the fabric 3 from shrinking, wrinkling or tearing due to high temperature, thereby ensuring that the printing area remains stable during the color development process, ensuring the continuity and efficiency of the color development process, and reducing errors and losses.

[0029] Preferably, in this embodiment, the track assembly 1 uses a high-temperature resistant, low-friction Teflon interwoven mesh track 12. The track 12 is made of polytetrafluoroethylene (PTFE, chemical formula (C2F4)). n Made of a material with excellent thermal stability and chemical inertness, the fabric 3 can operate for extended periods within a temperature range of -180℃ to 260℃, fully meeting the high-temperature environmental requirements of the fabric 3 during the coloring process. A significant characteristic of Teflon is its extremely low coefficient of friction. While this facilitates smooth movement of the fabric 3 at high temperatures, it also presents technical challenges, such as difficulty in adhesion and slippage during the initial feeding stage. To improve the stability of the fabric 3 feeding, a guide belt is installed on the surface of the track 12 along the forward direction. This guide belt is made of a material with certain frictional and tensile strength, and one end is fixedly connected to the front end of the track 12. When the equipment is running, the guide belt moves forward with the track 12, providing initial traction for the fabric 3. During operation, the front end of the fabric 3 to be colored is connected to the guide belt. Under the traction of the guide belt, the fabric 3 passes through the clamping area between the pressure roller 4 located above the front section of the track 12 and the needle plate 11 on the track 12. The downward pressure roller 4 is made of elastic bristles or rubber. It applies downward pressure as the fabric 3 passes through this area, causing the edges of the fabric 3 to adhere and be fixed to the needle plates 11 on both sides of the conveyor belt 12. After being accurately clamped and positioned, the fabric 3 smoothly enters the high-temperature treatment zone inside the color-developing machine along with the conveyor belt 12. Through the initial guidance of the guide belt and the positioning structure of the downward pressure roller 4 and needle plates 11, not only is the slippage of the fabric 3 caused by the low friction of the Teflon conveyor belt 12 resolved, but the automation, stability, and precision of the fabric 3 introduction are also achieved, ensuring uniform heating, reasonable tension, and accurate pattern alignment of the fabric 3 during the subsequent color-developing process. Furthermore, rollers 4 for winding and unwinding the fabric 3 are provided at both the inlet and outlet of the color-developing machine, respectively for transferring and collecting the color-developed fabric 3.

[0030] Please refer to Figure 4 In some embodiments, the adjusting member 13 includes an edge track 131 and a telescopic rod 132; the two ends of the telescopic rod 132 are respectively connected to the edge track 131 and one end of the track 12 in the width direction, and the telescopic rod 132 can change its own length to adjust the distance between the edge track 131 and the track 12; the needle plate 11 is connected to one end face of the edge track 131.

[0031] As described above, by using a simple and responsive telescopic rod 132 as the actuator, the lateral position of the needle plate 11 can be quickly and accurately adjusted, thereby adjusting the position of the fixed edge of the fabric 3 to match the tension requirements of fabrics 3 with different widths. This structure reduces reliance on traditional manual adjustment or mechanical slide rail systems, improving the automation level and adaptability of the entire machine. The telescopic rod 132 can be pneumatically or electrically driven and integrated into the edge rail 131, allowing for pre-adjustment or real-time adjustment of the distance between the needle plates 11 on both sides before the fabric 3 enters the coloring zone, adapting to different fabric widths or heat shrinkage states, thus maintaining uniform heating and stable fabric movement.

[0032] Please refer to Figures 2 to 4 Specifically, it also includes a hanging shaft assembly, which includes a support shaft 21 and a transmission component 22. The transmission component 22 is connected to both ends of the support shaft 21 along its length and is connected to the edge track 131 in a transmission connection. The support shafts 21 are staggered at a preset interval.

[0033] As described above, the staggered support shafts 21 provide multi-point guidance and support for the movement path of the track 12, improving the stability of the track 12's operation. Simultaneously, the staggered arrangement of the support shafts 21 causes the track 12 to move in a wave-like motion during its movement, effectively utilizing the coloring space and preventing the coloring machine from becoming too large. Furthermore, the linkage between the transmission component 22 and the edge rail 131 facilitates synchronized edge adjustment and track 12 conveying, ensuring the uniformity of fabric 3 transmission and reducing friction and deviation risks. In some embodiments, by setting 1.2m-2m support shafts 21 that traverse both ends of the coloring machine's housing, staggered vertically with each row or column spaced 0.5-1m apart, the track 12 can complete multiple directional changes along these shafts. The gear structures at both ends of the support shafts 21 engage with the racks of the edge rail 131, achieving synchronized edge adjustment and conveying while ensuring sufficient coloring space and preventing uneven heating of the fabric 3. In addition, the support shafts 21 are rotatably connected to the coloring machine housing, thereby achieving the positioning of the support shafts 21.

[0034] Preferably, the transmission component 22 includes a first transmission part 221 and a second transmission part 222. The first transmission part 221 is connected to the opposite end face of the edge track 131 on which the needle plate 11 is located, and the second transmission part 222 is connected to both the end face of the edge track 131 on which the needle plate 11 is located and the opposite end face.

[0035] As described above, by providing first and second drive units 222 at both ends of the edge track 131, the first drive unit 221 is connected to the opposite end face of the edge track 131 with the needle plate 11, and the second drive unit 222 is connected to both the end face and the opposite end face of the edge track 131 with the needle plate 11. This allows for tensioning of the entire track assembly 1 within the staggered arrangement of the support shafts 21, preventing collapse in a certain area from affecting the color development of the fabric 3, effectively avoiding needle plate 11 offset or uneven fabric 3 stretching due to unilateral force, and improving the accuracy of fabric feeding and fabric flatness. In some embodiments, the support shafts 21 are staggered vertically, with the first drive unit 221 located on the upper support shaft 21 and used to support the track assembly 1, and the second drive unit 222 located on the lower support shaft 21 and used to clamp the track assembly 1.

[0036] Please refer to Figure 5 Preferably, the second transmission part 222 includes a connecting rod 224 and at least two transmission gears 223. The two transmission gears 223 are rotatably connected to both ends of the connecting rod 224, and one end of the connecting rod 224 is connected to the hanging shaft. The two transmission gears 223 are respectively connected to the two end faces of the edge track 131.

[0037] As described above, the connecting rod 224 + double gear structure can achieve simultaneous movement at both ends of the edge track 131 under the drive of the hanging shaft on one side, improving adjustment efficiency and structural symmetry; reducing running deviations and ensuring the linearity and consistency of the needle plate 11 movement. In some embodiments, the connecting rod 224 is a U-shaped connecting rod 224, with its two ends connected to two transmission gears 223 respectively, and one end connected to the hanging shaft; similarly, the first transmission part 221 also uses the aforementioned transmission gear 223, which is rotatably connected to the hanging shaft.

[0038] Please refer to Figure 4 Specifically, the edge track 131 has a transmission groove 133 on both the end face of the needle plate 11 and its opposite end face.

[0039] As can be seen from the above description, by setting transmission grooves 133 on both sides of the edge track 131, a precise transmission channel can be provided to prevent jamming or misalignment during the adjustment process of the needle plate 11, so that the needle plate 11 can move more smoothly and accurately along the predetermined route, thereby improving the operational stability and lifespan of the equipment.

[0040] Please refer to Figure 4In some embodiments, the edge track 131 has a U-shaped cross-section, and the telescopic rod 132 is disposed in the U-shaped groove of the edge track 131. During the adjustment of the telescopic rod 132, the track 12 is at least partially located inside the U-shaped groove of the edge track 131.

[0041] As described above, the U-shaped track structure provides a stable guiding and protective environment, effectively preventing external debris interference or thermal deformation from affecting the mechanism's operation when the telescopic rod 132 is working. It also improves the matching degree between the track 12 and the track, reduces vibration and wear, and enhances the overall stability of the machine. In some embodiments, the edge track 131 of the U-shaped structure is a chain-type transmission structure, where each link is controlled by the telescopic rod 132, and there is a transmission margin between adjacent links to absorb the increased transmission stroke after the telescopic rod 132 is adjusted. The bottom of the track is embedded with the telescopic rod 132, and the sidewalls form sliding guide rails to ensure smooth sliding of the needle plate 11 in the track. Simultaneously, the edge portion of the track 12 is embedded inside the track to cooperate in operation and prevent deviation.

[0042] Please refer to Figure 1 and Figure 3 In some embodiments, the track assembly 1 further includes a drive member 14; the drive member 14 is connected to the edge track 131 and is used to drive the edge track 131 to move.

[0043] As described above, by setting a dedicated drive unit 14 to drive the edge track 131, the movement logic of the fixed part of the fabric 3 can be independently controlled, decoupled from the main movement of the track 12, improving the adjustment response speed and accuracy. This allows the color-changing machine to dynamically adjust the edge fixing points according to actual tension / temperature conditions, preventing deformation of the fabric 3. In some embodiments, gear transmission is used between the drive unit 14 and the track assembly 1. The drive unit 14 consists of two synchronous motors, located at two corners of the track 12.

[0044] In some embodiments, to prevent tearing and pattern deformation of fabric 3 due to heat shrinkage during the high-temperature color development process, an automatic adjustment structure combining pre-shrinkage calculation data and real-time sensor feedback is proposed to ensure that fabric 3 is maintained within a suitable tension range during the color development period. The specific steps are as follows:

[0045] I. Pre-shrinkage calculation stage:

[0046] Before fabric 3 enters the color-developing machine, its heat shrinkage characteristics are pre-evaluated and calculated. This calculation includes, but is not limited to, the following parameters: the material of the yarn used in fabric 3 (such as polyester fiber, nylon, etc.); the textile structure (plain weave, mesh, jacquard, etc.); the required color-developing temperature (usually between 190℃ and 250℃); the heating time and humid heat conditions.

[0047] Based on the above data, the possible width shrinkage rate of fabric 3 during the color development stage is calculated. For example, if a certain type of fabric 3 shrinks by about 5% in 3 minutes under a high temperature of 250℃, the system will predict its width after shrinkage and adjust the initial position of the needle plate 11 on the track 12 based on this, so that its initial set point is slightly larger than the expected width of fabric 3 after shrinkage by about 1cm, so as to form a buffer space.

[0048] II. Automatic Dynamic Adjustment Stage:

[0049] After fabric 3 is fed onto conveyor belt 12, it is clamped on both sides by needle plates 11 and enters the high-temperature zone of the color-developing machine. After one minute of color development, the equipment starts a dynamic adjustment program. One or both of the following two feedback methods can be used in parallel:

[0050] Method 1: Tension feedback adjustment based on load sensor

[0051] High-precision load sensors (force sensors) are installed on the edge tracks 131 on both sides of the track 12 to monitor the lateral tension of the fabric 3 on the needle plate 11 due to heat shrinkage in real time. This tension is collected by the system and compared in real time with the "maximum allowable tension" obtained by the fabric 3 during the pre-shrinking stage.

[0052] When the inward pulling force detected by the sensor gradually increases and approaches or exceeds the set threshold, the system automatically issues a command: controls the edge track 131 to finely shrink towards the center; drives the connected telescopic rod 132 to shorten its length; and the needle plate 11 moves synchronously towards the center to match the actual width of the fabric 3 after shrinkage.

[0053] This method enables automatic tension balance adjustment of fabric 3, preventing fabric 3 from tearing due to excessive tension and improving the integrity and reliability of the finished product.

[0054] Method 2: Width Prediction Adjustment Based on Infrared Temperature Sensor

[0055] As another control strategy, an infrared temperature sensor is installed on the inner side of the edge track 131 or in its adjacent area to monitor the surface temperature of the fabric 3 in real time during the coloring process.

[0056] When the temperature rises and reaches the shrinkage inflection point corresponding to the predicted temperature (e.g., 245℃ corresponds to a 5% shrinkage rate): the control system predicts the actual shrinkage degree of the fabric 3 based on the temperature rise process and the pre-shrinkage model; drives the telescopic rods 132 on both sides to shrink slightly, so that the distance between the needle plates 11 is slightly larger than the estimated width of the fabric 3 by about 0.5cm to 1cm, to ensure that the tension is moderate; to avoid the fabric 3 being too tensile due to the needle plates 11 being too wide or too narrow, which would make it difficult for the fabric 3 to be effectively tensioned.

[0057] This method does not require direct contact with the fabric 3, is suitable for high temperature and high humidity environments, and can quickly respond to temperature changes.

[0058] III. Synchronous Feedback and Security Mechanisms:

[0059] To ensure the stability and safety of the adjustment system, the two sensor signals can be used together and redundantly checked separately. When either sensor detects an abnormal value (such as a sudden change in tension or a temperature exceeding the threshold), the system can immediately stop the operation of the track 12 and issue an alarm signal. After the coloring is completed, the needle removal wheel located at the discharge end runs synchronously to work with the track 12 to peel the fabric 3 off the needle plate 11, preventing the fabric 3 from getting stuck.

[0060] This implementation method can dynamically adapt to the heat shrinkage characteristics of different types of fabric 3 during the color development process, effectively avoid the problem of sudden tension increase caused by excessive rigidity of the fixed structure, improve the equipment's adaptability to multiple types of fabrics, and significantly reduce fabric 3 wear, pattern deformation rate and equipment failure rate.

[0061] In summary, this utility model provides an intelligent color-developing machine for high-temperature fabric color development, possessing the dual advantages of structural innovation and high operational efficiency. It significantly improves existing color-developing technologies by addressing technical challenges such as tension imbalance, pattern misalignment, and inconsistent fabric width caused by fabric heat shrinkage. By incorporating adjustable adjustment components at both ends of the track, working in conjunction with a hanging shaft assembly featuring multi-point support and power transmission, dynamic adjustment of the needle plate spacing along the track width is achieved. This allows for responsive adjustment based on real-time fabric width changes under high-temperature conditions, ensuring the fabric tension remains within a safe range during the color development process. This effectively prevents issues such as localized wrinkles and edge tearing, significantly improving the accuracy of printed patterns and the yield rate of the printed fabric. In particular, the edge track and telescopic rod structure within the adjustment components greatly enhances the adjustment accuracy and response speed of the needle plate position, making it suitable for various fabric widths and materials, and also improving the automation level and flexible production capabilities of the equipment.

[0062] Furthermore, the track adopts a high-temperature resistant, low-friction Teflon interwoven mesh structure, and is equipped with a guide belt and a fixing structure for the pressure roller at the front end of the track. This ensures a smooth, reliable, and precise positioning of the fabric during the feeding process, effectively solving the problem of unstable fabric movement caused by slippage and offset before entering the coloring chamber, and enhancing the effect of initial tension control for fabric fixation. The staggered support shaft structure in the hanging shaft assembly not only improves the stability of the track's movement path but also creates a wave-like path for the fabric within the coloring machine, maximizing the use of the internal space of the machine, improving coloring efficiency, and saving equipment floor space. By arranging the first and second transmission structures at both ends of the edge track and using a connecting rod and double gear linkage, synchronous response and symmetrical adjustment of the edge track during the transmission process are achieved, effectively ensuring the balance and linearity of the needle plate adjustment, and further improving the flatness of the fabric movement.

[0063] Regarding tension control, this invention dynamically adjusts the length of the telescopic rod and the needle plate spacing by pre-calculating the fabric's heat shrinkage characteristics and combining real-time feedback data from a high-precision load sensor or infrared temperature sensor. This ensures the fabric maintains stable tension under different heat shrinkage conditions. This "prediction + feedback + response" collaborative control mode is compatible with various fabric types, heat shrinkage behaviors, and printing process requirements, preventing excessive or insufficient tension while also preventing fabric damage or pattern misalignment. Combined with the synchronized operation of the rear needle ejection wheel and the material output monitoring structure, this invention achieves closed-loop control and an anomaly warning mechanism throughout the entire color development process, ensuring the safety and reliability of the entire machine.

[0064] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
