Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile dyeing and finishing equipment technology, and in particular to an intelligent tension adjustment device for dyeing and finishing machinery. Background Technology
[0002] Textile dyeing and finishing is a process that uses chemical and physical methods to treat various fibers or fabrics to change their appearance, properties or add specific functions. The dyeing and finishing process mainly includes pretreatment, dyeing, printing and finishing.
[0003] In textile dyeing and finishing processes, fabric tension control plays a crucial role in product quality. Unstable fabric tension can lead to uneven dyeing, wrinkles, and stretching deformation, severely affecting the product's appearance and intrinsic quality. Traditional fabric tension adjustment devices in dyeing and finishing machinery typically employ manual or simple mechanical adjustment methods, which struggle to achieve precise control of fabric tension. Manual adjustment is not only inefficient but also highly dependent on the operator's experience and skill level. Mechanical adjustment lacks flexibility and cannot dynamically adjust based on the fabric's real-time operating status. Furthermore, fabric deviation can occur during dyeing and finishing; if not corrected promptly, this can exacerbate uneven tension and even damage the fabric. Therefore, it is necessary to design an intelligent fabric tension adjustment device for dyeing and finishing machinery to address these issues. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent tension adjustment device for dyeing and finishing machinery.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fabric tension intelligent adjustment device for dyeing and finishing machinery includes a base plate with multiple fixing holes on its upper surface. A support frame is fixedly installed on the upper surface of the base plate. Displacement sensors are fixedly installed on the inner walls of both sides of the support frame via mounting mechanisms. A connecting block is rotatably installed on the inner bottom wall of the support frame via a support frame. A correction roller is rotatably installed at the end of the connecting block via a correction frame. A guide plate is fixedly installed on the outer bottom wall of the correction frame. A sliding rod is slidably installed on the outer wall of the guide plate through a movable opening. An electric actuator is fixedly installed on the inner bottom wall of the support frame. A connecting frame is fixedly installed on the telescopic end of the electric actuator. Both ends of the sliding rod are fixedly connected to the inside of the connecting frame. A screw is rotatably installed on the inner bottom wall of the support frame via a lifting frame. A servo motor connected to the screw is fixedly installed on the upper end face of the lifting frame. A moving block is threadedly installed on the outer wall of the screw via a limiting mechanism. A connecting plate is fixedly connected to the upper end face of the moving block via a connecting mechanism. Two spring telescopic rods are fixedly installed on the upper end face of the connecting plate. The telescopic ends of the two spring telescopic rods are rotatably installed on a tension adjusting roller via an upper top frame. A pressure sensor is fixedly installed on the upper end face of the connecting plate. The telescopic end of the pressure sensor is fixedly connected to the bottom wall of the connecting plate.
[0007] Preferably, the mounting mechanism includes a mounting plate fixedly mounted on the inner wall of the support frame, and the displacement sensor is fixedly mounted on the upper surface of the mounting plate.
[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the lifting frame, and the limiting rod slides through the moving block.
[0009] Preferably, the connecting mechanism includes two connecting rods fixedly installed on the upper end face of the movable block, and the ends of the two connecting rods are fixedly connected to the bottom wall of the connecting plate.
[0010] Preferably, a limiting roller is rotatably installed inside the support frame, and the limiting roller is positioned between the correction roller and the tension adjusting roller.
[0011] Preferably, a controller is fixedly installed on the bottom wall of the support frame, and the controller is electrically connected to two displacement sensors, an electric actuator, a servo motor, and a pressure sensor.
[0012] The beneficial effects of this utility model are:
[0013] 1. By setting up components such as a screw, servo motor, spring telescopic rod, tension adjusting roller and pressure sensor, the pressure sensor monitors the pressure on the tension adjusting roller in real time. When there is a deviation between the pressure value and the preset tension value, the controller controls the servo motor to drive the screw to rotate, so that the moving block moves up and down, thereby driving the tension adjusting roller to finely adjust the tension of the fabric. The spring telescopic rod can also play a buffering role to avoid damaging the fabric due to excessive adjustment.
[0014] 2. By setting up components such as displacement sensors, connecting blocks, electric push rods and slide rods, the displacement sensors monitor the fabric position in real time. Once deviation is detected, the signal is transmitted to the controller. The controller controls the extension and retraction of the electric push rod, which drives the slide rod to move, causing the correction frame to rotate, thereby adjusting the angle of the correction roller and correcting the deviation of the fabric.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-7The intelligent tension adjustment device for dyeing and finishing machinery includes a base plate 1. Multiple fixing holes are provided on the upper surface of the base plate 1. A support frame 2 is fixedly installed on the upper surface of the base plate 1. Displacement sensors 5 are fixedly installed on the inner walls of both sides of the support frame 2 via mounting mechanisms. A connecting block 7 is rotatably installed on the inner bottom wall of the support frame 2 via a support frame 6. A correction roller 9 is rotatably installed at the end of the connecting block 7 via a correction frame 8. A guide plate 10 is fixedly installed on the outer bottom wall of the correction frame 8. A sliding rod 11 is slidably installed on the outer wall of the guide plate 10 through a movable opening. An electric push rod 12 is fixedly installed on the inner bottom wall of the support frame 2. A connecting frame 13 is fixedly installed at the telescopic end of the electric push rod 12. Both ends of the sliding rod 11 are connected to the connecting frame 13. The frame 13 is fixedly connected internally. The bottom wall of the support frame 2 is rotatably mounted with a screw 15 via a lifting frame 14. The upper end of the lifting frame 14 is fixedly mounted with a servo motor 16 connected to the screw 15. The outer wall of the screw 15 is threadedly mounted with a moving block 18 via a limiting mechanism. The upper end of the moving block 18 is fixedly connected with a connecting plate 20 via a connecting mechanism. The upper end of the connecting plate 20 is fixedly mounted with two spring telescopic rods 21. The telescopic ends of the two spring telescopic rods 21 are rotatably mounted with a tension adjusting roller 23 via an upper top frame 22. The upper end of the connecting plate 20 is fixedly mounted with a pressure sensor 24. The telescopic end of the pressure sensor 24 is fixedly connected to the bottom wall of the connecting plate 20.
[0025] Furthermore, the support frame 6 and the connecting block 7 are connected by precision bearings, which allow for flexible rotation and low friction. The electric push rod 12 has a fast response speed and can complete the extension and retraction action in a short time, thereby driving the slide rod 11 to slide quickly within the moving opening of the guide plate 10, realizing timely adjustment of the angle of the correction roller 9, and effectively correcting the problem of fabric deviation.
[0026] The mounting mechanism includes a mounting plate 4 fixedly installed on the inner wall of the support frame 2, and a displacement sensor 5 fixedly installed on the upper surface of the mounting plate 4.
[0027] Furthermore, the surface of the mounting plate 4 is treated with anti-slip material to effectively prevent the displacement sensor 5 from sliding during installation and use. The displacement sensor 5 has high-precision detection capability and can monitor the positional changes of the fabric in real time and accurately, with the accuracy error controlled within a very small range.
[0028] The limiting mechanism includes a limiting rod 17 fixedly installed inside the lifting frame 14, and the limiting rod 17 slides through the moving block 18.
[0029] Furthermore, the fit clearance between the limiting rod 17 and the moving block 18 is precisely designed to ensure that the moving block 18 slides smoothly along the limiting rod 17 while effectively restricting the rotation of the moving block 18, so that the moving block 18 can only move up and down in a straight line under the drive of the screw 15, thereby improving the accuracy of tension adjustment.
[0030] The connecting mechanism includes two connecting rods 19 fixedly installed on the upper surface of the movable block 18, and the ends of the two connecting rods 19 are fixedly connected to the bottom wall of the connecting plate 20.
[0031] Furthermore, the connecting rod 19 is made of high-strength alloy material, which has good tensile and bending resistance, and can stably transmit the displacement of the moving block 18 to the connecting plate 20, ensuring that the position adjustment of the tension adjusting roller 23 is accurate.
[0032] A limiting roller 3 is rotatably installed inside the support frame 2, and the limiting roller 3 is located between the correction roller 9 and the tension adjustment roller 23.
[0033] Furthermore, the surface of the limiting roller 3 is specially treated to have a low coefficient of friction and high wear resistance, which can reduce wear on the fabric surface while limiting and guiding the fabric, thus ensuring the quality of the fabric.
[0034] A controller 25 is fixedly installed on the inner bottom wall of the support frame 2. The controller 25 is electrically connected to two displacement sensors 5, an electric push rod 12, a servo motor 16, and a pressure sensor 24.
[0035] Furthermore, the controller 25 adopts a high-performance microprocessor with powerful data processing and analysis capabilities. It can quickly receive and process signals from various sensors and precisely control the movement of the electric actuator 12 and the servo motor 16 according to the preset program, thereby realizing intelligent adjustment of fabric tension and deviation.
[0036] When using this invention, the operator first places the fabric on top of the correction roller 9, then smoothly pulls the fabric through the bottom of the limiting roller 3, and finally positions the fabric accurately above the tension adjusting roller 23. When the fabric starts running, the displacement sensors 5 on both sides monitor the position of the fabric in real time. Once the fabric is detected to be off-center, the displacement sensor 5 immediately transmits the signal to the controller 25. The controller 25 quickly analyzes the signal data and, based on the direction and degree of the off-center movement, precisely controls the electric push rod 12 to extend and retract. The extension and retraction of the electric push rod 12 drives the slide rod 11 to move through the connecting frame 13. Since the slide rod 11 slides within the moving opening of the guide plate 10, the correction frame 8 can rotate around the connecting block 7, thereby achieving precise adjustment of the angle of the correction roller 9 and quickly correcting the off-center fabric to the normal operating position.
[0037] In terms of fabric tension adjustment, pressure sensor 24 continuously monitors the pressure on tension adjustment roller 23. This pressure value directly reflects the current tension of the fabric. When the pressure value detected by pressure sensor 24 deviates from the preset tension value, it immediately transmits this deviation signal to controller 25. After receiving the signal, controller 25 quickly processes and analyzes the data, and then controls servo motor 16 to rotate accordingly. Servo motor 16 drives screw 15 to rotate. Screw 15 causes moving block 18 to move precisely up and down under the limiting constraint of limit rod 17 through the thread action. The movement of moving block 18 is transmitted to connecting plate 20 through connecting rod 19. Connecting plate 20 then drives tension adjustment roller 23 to move up and down through spring telescopic rod 21 and upper top frame 22, thereby finely adjusting the tension of the fabric to ensure that the fabric tension is always stable within the preset optimal value range.
[0038] The ingenious design of the spring telescopic rod 21 plays an important buffering role in the entire tension adjustment process. It can effectively avoid excessive adjustment during tension adjustment, prevent unnecessary damage to the fabric, and protect the integrity and quality of the fabric. The setting of the limiting roller 3 further enhances the stability of the fabric during operation, and plays a good role in limiting and guiding the fabric, ensuring that the fabric can run smoothly along the predetermined path.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
