Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fabric dyeing, specifically to a fabric dyeing guiding mechanism. Background Technology
[0002] Synthetic fiber fabrics occupy an important position in the textile industry, favored for their superior performance and wide range of applications. As consumers' demands for the color and quality of textiles continue to rise, the dyeing process of synthetic fiber fabrics is receiving increasing attention. Currently, the main dyeing method for synthetic fiber fabrics is immersion dyeing, which involves soaking the greige fabric in a dye solution, allowing the dye to penetrate the fabric. While this method is simple and easy to implement, it suffers from problems such as uneven dye distribution and low dyeing efficiency. To improve dyeing results, some companies have begun to introduce spray dyeing technology, which uses nozzles to evenly spray dye onto the greige fabric.
[0003] Currently, most dyeing guiding mechanisms typically guide the fabric only through the lifting rollers and drive rollers. This has the following drawbacks: the force of the guiding mechanism cannot be automatically adjusted, thus failing to maintain stable tension, causing wrinkles or excessive stretching of the fabric, thereby reducing the uniformity and quality of dyeing. Utility Model Content
[0004] The purpose of this invention is to provide a dyeing guide mechanism for fabrics, which solves the problem that the force of the guide mechanism cannot be automatically adjusted, thus failing to maintain stable tension, causing wrinkles or excessive stretching of the fabric, thereby reducing the uniformity and quality of dyeing.
[0005] To achieve the aforementioned objectives, this utility model employs the following technical solution: a fabric dyeing guide mechanism, comprising a sealed door, the sealed door being rotatably connected to the front side of the outer wall of a dyeing chamber via a hinge, a fabric lifting roller being rotatably mounted inside the dyeing chamber, a PLC controller being fixed to the right side of the outer wall of the dyeing chamber, a drive motor being fixed to the right side of the outer wall of the dyeing chamber, the drive motor being electrically connected to the PLC controller, the output shaft of the drive motor passing through the right side of the outer wall of the dyeing chamber and being fixedly connected to the right end of the fabric lifting roller, and two... A first guide roller is provided. An installation box is fixed inside the dyeing chamber. A transmission roller is movably mounted on the rear side of the installation box. Two tension sensors are fixed on the top surface of the installation box and electrically connected to a PLC controller. Bearing seats are fixed on the top surfaces of both tension sensors. A detection roller is rotatably mounted between the two bearing seats. A first electric push rod is fixed on the top surface of the installation box and electrically connected to the PLC controller. A U-shaped seat is fixed to one end of the telescopic rod of the first electric push rod. A second guide roller is rotatably mounted inside the U-shaped seat.
[0006] Preferably, the top surface of the mounting box has two limiting holes, and limiting posts are slidably inserted into the two limiting holes respectively. The top ends of the two limiting posts are fixedly connected to the bottom surface of the U-shaped seat.
[0007] Preferably, a second electric push rod is fixed inside the mounting box. The second electric push rod is electrically connected to the PLC controller. One end of the telescopic rod of the second electric push rod is fixed to a U-shaped frame, and the transmission roller is rotatably arranged inside the U-shaped frame.
[0008] Preferably, a connecting pipe is fixedly connected to the right side of the outer wall of the dyeing chamber, and a conveying pipe is provided at the right end of the connecting pipe. One end of the conveying pipe penetrates the top surface of the dyeing chamber and extends into the interior of the dyeing chamber. A circulation pump is fixedly connected to the outer wall of the conveying pipe, and a nozzle is fixed at one end of the conveying pipe.
[0009] Preferably, a filter cylinder is detachably provided between the connecting pipe and the conveying pipe, and a filter screen is fixed inside the filter cylinder.
[0010] Preferably, the inner walls of both the connecting pipe and the conveying pipe are provided with internal threads, and the outer wall of the filter cylinder is provided with external threads, and the external threads are threadedly connected to the internal threads.
[0011] Compared with existing technologies, the fabric dyeing guiding mechanism that adopts the above technical solution has the following beneficial effects:
[0012] 1. In operation, the worker guides the fabric into the dyeing chamber through the opening. The fabric end passes through the two first guide rollers to the end of the dyeing chamber. Then, the fabric is pressed against the outer walls of the transmission roller, detection roller, and second guide roller and pulled towards the opening of the dyeing chamber. At this point, the worker passes the fabric end over the lifting roller, ensuring that both the beginning and end of the fabric are at the opening of the dyeing chamber. The worker then sews the beginning and end of the fabric together, forming a closed loop within the dyeing chamber. After sewing, the sealing door is closed. When dyeing is required, the worker starts the drive motor to rotate the lifting roller. Simultaneously, the transmission roller is moved, subjecting the fabric between it and the lifting roller to two traction forces. Meanwhile, the fabric is immersed in dye solution inside the dyeing chamber. During this process, the detection roller and tension sensor monitor the tension changes of the fabric in real time and transmit the information to the PLC controller. Based on the received information, the PLC controller activates the first electric push rod, adjusting the U-shaped seat and the second guide roller to ensure that the tension is always maintained within the ideal range. By using the fabric lifting roller, drive motor, first guide roller, mounting box, transmission roller, tension sensor, bearing seat, detection roller, first electric push rod, U-shaped seat and second guide roller in combination, the guidance of the fabric during the dyeing process is realized. At the same time, the force of the guiding mechanism can be automatically adjusted to maintain stable tension, avoid wrinkles or excessive stretching of the fabric, and improve the uniformity and quality of dyeing.
[0013] Second, during use, the combination of the limiting holes and limiting posts facilitates the limiting of the U-shaped seat and the second guide roller, preventing deviation and swaying, thereby improving the stability of the U-shaped seat and the second guide roller during lifting. When the PLC controller receives information from the tension sensor, it activates the second electric push rod to adjust the U-shaped frame back and forth, which in turn drives the transmission roller to move back and forth, further adjusting the tension of the fabric and avoiding dyeing problems caused by uneven tension.
[0014] Thirdly, during use, by starting the circulation pump, the dye liquor inside the dyeing chamber can be transported to the nozzles through the connecting pipes and delivery pipes, facilitating the dyeing operation of the fabric and further improving the dyeing quality. The use of the filter cartridge and filter screen effectively filters impurities in the dye liquor, preventing nozzle clogging and ensuring smooth nozzle operation. The use of internal and external threads allows operators to easily disassemble and assemble the filter cartridge and filter screen, facilitating cleaning or replacement. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] like Figures 1-3 As shown, a fabric dyeing guide mechanism includes a sealed door 1, which is rotatably connected to the front of the outer wall of a dyeing chamber 2 via a hinge. A fabric lifting roller 3 is rotatably mounted inside the dyeing chamber 2. A PLC controller (Siemens S7-200) is fixed to the right side of the outer wall of the dyeing chamber 2. A drive motor 4 is also fixed to the right side of the outer wall of the dyeing chamber 2 and is electrically connected to the PLC controller. The output shaft of the drive motor 4 passes through the right side of the outer wall of the dyeing chamber 2 and is fixedly connected to the right end of the fabric lifting roller 3. Two first guide rollers 5 are rotatably mounted inside the dyeing chamber 2. A mounting box 6 is fixed inside the dyeing chamber 2 for mounting... A transmission roller 7 is movably mounted on the rear side of the mounting box 6. Two tension sensors 8 are fixed on the top surface of the mounting box 6. The tension sensors 8 are existing technology, and the model of the tension sensors 8 is FMS-T300-10N. The tension sensors 8 are electrically connected to the PLC controller. Bearing seats 9 are fixed on the top surface of both tension sensors 8. A detection roller 10 is rotatably mounted between the two bearing seats 9. A first electric push rod 11 is fixed on the top surface of the mounting box 6. The first electric push rod 11 is electrically connected to the PLC controller. A U-shaped seat 12 is fixed to one end of the telescopic rod of the first electric push rod 11. A second guide roller 13 is rotatably mounted inside the U-shaped seat 12.
[0022] In operation, the worker guides the fabric into the dyeing chamber 2 through its opening. The fabric end is then passed sequentially through the two first guide rollers 5 to the end of the dyeing chamber 2. Next, the fabric is pressed against the outer walls of the drive roller 7, the detection roller 10, and the second guide roller 13, and pulled towards the opening of the dyeing chamber 2. The worker then passes the fabric end over the lifting roller 3, ensuring both ends are at the opening of the dyeing chamber 2. The worker then sews the fabric ends together, forming a closed loop within the dyeing chamber 2. After sewing, the chamber can be closed. When dyeing is required, the operator starts the drive motor 4 to rotate the fabric lifting roller 3. Simultaneously, the transmission roller 7 moves, subjecting the fabric between the lifting roller 3 and the fabric to two traction forces. At the same time, the fabric is immersed in dye solution inside the dyeing chamber 2. During this process, the detection roller 10 and tension sensor 8 monitor the tension changes of the fabric in real time and transmit the information to the PLC controller. Based on the received information, the PLC controller activates the first electric push rod 11, causing the U-shaped seat 12 and the second guide roller 13 to adjust their height, ensuring that the tension is always maintained within the ideal range. Through the coordinated use of the fabric lifting roller 3, drive motor 4, first guide roller 5, mounting box 6, transmission roller 7, tension sensor 8, bearing seat 9, detection roller 10, first electric push rod 11, U-shaped seat 12, and second guide roller 13, guidance is achieved during the fabric dyeing process. The force of the guiding mechanism can be automatically adjusted to maintain stable tension, preventing wrinkles or excessive stretching of the fabric, thus improving the uniformity and quality of dyeing.
[0023] like Figure 2 and Figure 3 As shown, the top surface of the mounting box 6 has two limiting holes 14, and limiting posts 15 are slidably inserted into the two limiting holes 14 respectively. The top ends of the two limiting posts 15 are fixedly connected to the bottom surface of the U-shaped seat 12 respectively.
[0024] In use, the cooperation of the limiting hole 14 and the limiting post 15 helps to limit the U-shaped seat 12 and the second guide roller 13, preventing deviation and shaking, thereby improving the stability of the U-shaped seat 12 and the second guide roller 13 when they are raised and lowered.
[0025] like Figures 1-4 As shown, a second electric push rod 16 is fixed inside the mounting box 6. The second electric push rod 16 is electrically connected to the PLC controller. One end of the telescopic rod of the second electric push rod 16 is fixed to a U-shaped frame 17. The transmission roller 7 is rotatably set inside the U-shaped frame 17. A connecting pipe 18 is fixedly connected to the right side of the outer wall of the dyeing chamber 2. A conveying pipe 19 is provided at the right end of the connecting pipe 18. One end of the conveying pipe 19 penetrates the top surface of the dyeing chamber 2 and extends into the interior of the dyeing chamber 2. A circulating pump 20 is fixedly connected to the outer wall of the conveying pipe 19. A nozzle 21 is fixedly connected to one end of the conveying pipe 19.
[0026] During operation, when the PLC controller receives information from the tension sensor 8, it activates the second electric push rod 16 to adjust the U-shaped frame 17 back and forth, thereby driving the transmission roller 7 to move back and forth, further adjusting the tension of the fabric and avoiding dyeing problems caused by uneven tension. By activating the circulating pump 20, the dye liquor inside the dyeing chamber 2 can be transported to the nozzle 21 through the connecting pipe 18 and the conveying pipe 19, which facilitates the dyeing operation on the fabric and further improves the dyeing quality.
[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a filter cylinder 22 is detachably provided between the connecting pipe 18 and the conveying pipe 19. A filter screen 23 is fixed inside the filter cylinder 22. The inner walls of both the connecting pipe 18 and the conveying pipe 19 are provided with internal threads 24, and the outer wall of the filter cylinder 22 is provided with external threads 25. The external threads 25 and the internal threads 24 are threadedly connected.
[0028] During use, the combination of filter cartridge 22 and filter screen 23 facilitates the filtration of impurities in the dye liquor, preventing clogging of nozzle 21 and effectively ensuring the smooth operation of nozzle 21. The combination of internal thread 24 and external thread 25 allows operators to easily disassemble and assemble filter cartridge 22 and filter screen 23, making it convenient to clean or replace them.
