Description

Technical Field

[0001] This utility model relates to the field of dyeing equipment technology, and more specifically, to a tension adjustment mechanism for a fabric dyeing machine. Background Technology

[0002] Continuous dyeing machines are core equipment in the textile dyeing and finishing field. Their advantages lie in high efficiency, continuous operation, and standardization. They can complete the dyeing of fabrics without interruption and are especially suitable for processing scenarios with large batches, high capacity, and stable requirements for color fastness and color difference.

[0003] To achieve multi-color or deep dyeing effects, continuous dyeing machines are typically equipped with multiple dyeing vats. This significantly increases the distance the fabric needs to travel from the feed end to the take-up end. During this long-distance transport, the resistance, gravity, and the force of the dye liquor in each dyeing vat vary at different stages of the transport process. This results in the fabric having low tension when it first enters the dyeing machine, fluctuating tension after passing through multiple dyeing vats in the middle section, and high tension near the take-up end due to changes in the take-up speed. This uneven tension can easily cause local wrinkles and stretching deformation in the fabric, directly affecting the dyeing uniformity and the quality of the finished fabric. Furthermore, existing tension adjustment mechanisms mostly use a simple structure of fixed rollers and springs, which can only adjust the overall tension of the fabric and cannot make targeted dynamic adjustments based on the tension differences at the front, middle, and rear ends of the fabric, making it difficult to adapt to the tension requirements of different positions in real time. Therefore, the invention requires a new solution to this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tension adjustment mechanism for a fabric dyeing machine.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: Tension adjustment mechanism of a fabric dyeing machine, such as Figure 1 As shown, the apparatus includes several dyeing chambers 1, with tension regulating chambers 2 located between adjacent dyeing chambers 1. Tension regulating mechanisms 3 are symmetrically arranged on both sides of the inner wall of the tension regulating chamber 2. The tension regulating mechanism 3 includes a traction roller 301, an adjusting roller 302, a tension detection component 4, a drive component 6, and a control panel 303. The traction roller 301 is located between the dyeing chamber 1 and the tension regulating chamber 2. A guide roller is rotatably connected to the bottom of the dyeing chamber 1. The adjusting roller 302 is rotatably connected inside the tension regulating chamber 2. The guide roller and the adjusting roller 302 are located on both sides of the traction roller 301. The height of the traction roller 301 is higher than the height of the guide roller and the adjusting roller 302. The fabric passes through the traction roller 301, the guide roller, the traction roller 301, and the adjusting roller 302 in sequence. The traction roller 301 is driven to rotate by a motor, and the fabric is conveyed by the several traction rollers 301 with a stable traction force.

[0017] like Figure 1 As shown, the tension detection assembly 4 includes a slider 401 and a pressure sensor 402. The two ends of the adjusting roller 302 are rotatably connected to two symmetrically arranged sliders 401. The sensing end of the pressure sensor 402 is fixedly connected to the bottom of the slider 401. The pressure sensor 402 is used to detect the pressure on the slider 401, thereby obtaining the tension of the fabric conveyed to that area. The drive assembly 6 includes a second motor 601, a ball screw 602, a screw nut 603, and a support plate 604. The inner walls of the tension regulating chamber 2 are symmetrically provided with slide rails 7 on both sides. On the side of the two slide rails 7 closest to each other, there are symmetrically formed slide grooves 8 and 9. A protrusion 10 is integrally formed on the side of the slider 401 away from the regulating roller 302, and the protrusion 10 is slidably connected in the slide groove 8. The 2 slide grooves 9 are symmetrically arranged on both sides of the slide groove 8. Two protrusions 11 are integrally formed on the side of the support plate 604 closest to the slide rails 7, and the two protrusions 11 are slidably connected in the 2 slide grooves 9, allowing the slider 401 and the support plate 604 to reciprocate along the height direction on the slide rails 7. like Figure 1 As shown, the support plate 604 has a through hole 13 for the ball screw 602 to pass through. The screw nut 603 is threadedly connected to the ball screw 602. The top surface of the screw nut 603 is fixedly connected to the bottom surface of the support plate 604. The bottom end of the ball screw 602 is connected to the second motor 601. The first protrusion 10 and the second protrusion 11 can restrict the rotation of the slider 401 and the support plate 604, so that when the ball screw 602 rotates, it can drive the screw nut 603 to push the support plate 604 up and down, thereby adjusting the height of the adjusting roller 302. The control panel 303 is electrically connected to the first motor 5, the second motor 601, and the pressure sensor 402. The control panel 303 has preset target tension values ​​for different fabrics. The pressure sensor 402 transmits the detected pressure value to the control panel. The tension plate 303 is compared with the target tension value. When the adjusting roller 302 moves downward, the distance between it and the traction roller 301 is increased, thereby increasing the tension. When the adjusting roller 302 moves upward, the distance between it and the traction roller 301 is decreased, thereby decreasing the tension. By setting several tension detection components 4 and control panel 303, the real-time tension value of each part of the fabric can be detected in real time and compared with the preset target tension value. The position of the adjusting roller 302 is automatically adjusted by the drive component 6 to realize the automatic and precise adjustment of the tension of each part of the fabric, ensuring the tension balance of each part of the fabric and effectively ensuring the dyeing quality of the fabric. The control panel 303 can preset a variety of target tension values ​​corresponding to different fabrics, which can adapt to the tension requirements of fabrics of different materials and thicknesses, and has a wide range of applications.

[0018] like Figure 1As shown, the bottom of the tension regulating chamber 2 is provided with a support block 12. The bottom of the second motor 601 is fixedly connected to the top surface of the support block 12. The bottom of the tension regulating chamber 2 is provided with a drain port 15 for draining liquid that seeps out during fabric conveying. The top surface of the support block 12 is higher than the height of the drain port 15. The support block 12 is raised to prevent liquid from contacting the second motor 601. The top surface of the support block 12 is provided with a telescopic rod 14. The telescopic rod 14 and the ball screw 602 are located on the same vertical horizontal plane. The telescopic rod 14 stretches when the support plate 604 rises and contracts when it falls. The telescopic rod 14 makes the support plate 604 move more smoothly up and down. The top of the ball screw 602 is welded and fixed with a stop block 16 to limit the movement distance of the support plate. The drive assembly 6 adopts a transmission method of motor and ball screw, which has the characteristics of fast response speed and high transmission accuracy. It can quickly respond to tension changes and adjust the position of the driven regulating roller 302 in time to ensure the stability of fabric tension and avoid dyeing problems caused by tension fluctuations.

[0019] Working principle: First, based on the material and thickness of the fabric to be dyed, the corresponding target tension value is selected in the control module. The pressure sensor 402 detects the pressure on the adjusting roller 302 in real time and transmits the detection signal to the control module. When the control module calculates the corresponding tension based on the pressure value, it compares the real-time tension value with the target tension value. When the detected value exceeds the range of the target tension value, the control motor 601 is rotated clockwise, which drives the lead screw nut 603 to move the adjusting roller 302 upward to reduce the tension value to the target value. When the detected value is below the range of the target tension value, the control motor 601 is rotated counterclockwise, which drives the lead screw nut 603 to move the adjusting roller 302 downward to increase the tension value to the target value.

All technical solutions falling within the scope of this utility model's concept are protected.
