Abstract
Description
Technical Field
[0001] This application relates to the field of reed spinning technology, and in particular to a real-time vibration compensation device for reed spinning based on inertial sensors. Background Technology
[0002] The high-speed reed divider is an important component of textile machinery. During high-speed operation, due to manufacturing errors, installation errors, and inconsistent wear of various parts, the overall mass distribution is easily uneven, resulting in an imbalance. This imbalance causes the reed divider to generate severe vibration and noise during operation, which not only affects the quality of textile products but also shortens the service life of the reed divider and related components, increasing equipment maintenance costs.
[0003] Currently, some traditional solutions involve adding counterweights to the reed for balance adjustment. However, this method has significant limitations. Fixed counterweights cannot be adjusted in real time according to the actual operation of the reed, making it difficult to achieve precise dynamic balance. Moreover, when the working state of the reed changes, such as when the speed changes or when processing different types of fabrics, the balancing effect of the fixed counterweights will be greatly reduced, failing to meet the high requirements of dynamic balance for high-speed reeds. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a real-time vibration compensation device for reeds based on inertial sensors, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0005] To achieve the above objectives, this application adopts the following technical solution: a real-time vibration compensation device for a split reed based on an inertial sensor, comprising two support plates and a split reed body. Square grooves are formed on both sides of the two support plates, and connecting grooves are formed on both sides of the square grooves. A compensation component is installed inside the square grooves. Two brackets are installed on the outer side of the support plates, and a wiring plate is installed in the middle of the two brackets. Multiple wiring holes are formed on the inner wall of the wiring plate. Buffer components are installed on both sides of the wiring plate. An inertial sensor body is installed above the split reed body. An adjustment component is installed between the two support plates.
[0006] In a preferred embodiment, the compensation component includes a damping tube, one end of a buffer spring is fixedly connected to the inner wall of the damping tube, and one end of the buffer spring is fixedly connected to a movable column. Two magnetic strips are installed on the outer edge of the movable column, and a reed body is connected to the outer side of the movable column. The movable column and the magnetic strips are slidably connected to the inner wall of the damping tube.
[0007] By adopting the above technical solution, the buffering force of the buffer spring can be used to effectively alleviate the force of the reed body during movement, further ensuring the stability of the reed body during yarn feeding, and effectively buffering the vibration force during equipment operation, ensuring the stability of the reed body, and further ensuring that the yarn inside the reed body will not shift and become tangled.
[0008] In a preferred embodiment, a magnetic plate is installed on the inner wall of the connecting groove, and the magnetic plate and the magnetic strip have the same magnetic pole on the side that are close to each other.
[0009] By adopting the above technical solution, the repulsive force of magnetic similarity can be used to buffer the vibration force of the reed body from both sides of the damping tube. Furthermore, it can be combined with buffer springs to reduce the vibration force of the reed body from different directions.
[0010] In a preferred embodiment, the wiring board has elongated slots on both sides, and movable blocks are installed on the outer walls of the two brackets. One end of a return spring is fixedly connected to the upper and lower sides of the movable blocks, and the ends of the two return springs away from the movable blocks are fixedly connected to the inner wall of the elongated slots. The movable blocks are slidably connected inside the elongated slots.
[0011] By adopting the above technical solution, the routing plate can be stably set on one side of the reed body. Furthermore, when the yarn passes through the inner wall of the routing hole, the position of the routing plate can be slightly adjusted by the elastic force of the return spring, which will prevent the yarn from twisting. The movable state of the routing plate can ensure the adaptability of the yarn during routing.
[0012] In a preferred embodiment, the adjustment assembly includes a frame, a motor is mounted on the outer side of the support plate, a lead screw is fixedly connected to the power output shaft of the motor, a slider is threadedly connected to the outer edge of the lead screw, and the inertial sensor body is mounted on the top of the slider.
[0013] By adopting the above technical solution, the drive motor can drive the lead screw to rotate, which in turn can drive the slider to slide on the inner wall of the frame. Furthermore, the position of the inertial sensor body can be adjusted, and the inertial sensor body can be used to monitor the tilt angle and state of the yarn at different positions.
[0014] In a preferred embodiment, a ring is installed on the inner wall of the frame, and the end of the lead screw away from the motor is rotatably connected to the inner wall of the ring.
[0015] By adopting the above technical solution, the lead screw can be used to limit the rotation, thereby ensuring the stability of the lead screw during rotation and preventing it from shifting or swaying at will.
[0016] In a preferred embodiment, the wiring board is positioned corresponding to the reed body.
[0017] By adopting the above technical solution, the yarn can be pre-sorted before entering the reed body using the yarn guide plate and yarn guide holes, making it more convenient to thread the yarn through the reed and better maintaining the stable tension of the yarn.
[0018] The beneficial effects of this application are:
[0019] This inertial sensor-based real-time vibration compensation device for reed splitters effectively mitigates the force of the reed body during movement by using a buffer spring. This further ensures the stability of the reed body during yarn feeding and effectively buffers the vibration force during equipment operation, preventing the yarn inside the reed body from shifting and tangling. Furthermore, the magnetic plate and magnetic strip can buffer the vibration force of the reed body from both sides of the damping tube. In addition, the buffer spring can be used to reduce the vibration force of the reed body from different directions, improving the overall shock absorption.
[0020] This inertial sensor-based real-time vibration compensation device for reeds uses a drive motor to rotate a lead screw, which in turn causes a slider to slide along the inner wall of a frame. Furthermore, the position of the inertial sensor body can be adjusted, allowing the inertial sensor body to monitor the tilt angle and state of the yarn at different positions.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0029] Reference Figure 1-5 The real-time vibration compensation device for a split reed based on an inertial sensor includes two support plates 1 and a split reed body 9. Square grooves 2 are provided on both sides of the two support plates 1, and connecting grooves 3 are provided on both sides of the square grooves 2. Compensation components are installed inside the square grooves 2. Two brackets 10 are installed on the outer side of the support plates 1, and a wiring plate 11 is installed in the middle of the two brackets 10. Multiple wiring holes 12 are provided on the inner wall of the wiring plate 11. Buffer components are installed on both sides of the wiring plate 11. An inertial sensor body 20 is installed on the top of the split reed body 9. An adjustment component is installed between the two support plates 1.
[0030] See Figure 1 - Figure 3 The compensation component includes a damping tube 5, with one end of a buffer spring 6 fixedly connected to the inner wall of the damping tube 5. A movable column 7 is fixedly connected to one end of the buffer spring 6. Two magnetic strips 8 are installed on the outer edge of the movable column 7, and a reed body 9 is connected to the outer side of the movable column 7. Both the movable column 7 and the magnetic strips 8 are slidably connected to the inner wall of the damping tube 5. This allows the buffering force of the buffer spring 6 to effectively alleviate the force of the reed body 9 during movement, further ensuring the stability of the reed body 9 during yarn feeding and effectively buffering the vibration force during equipment operation, ensuring the stability of the reed body 9. Furthermore, it ensures that the yarn inside the reed body 9 will not shift or become entangled.
[0031] See Figure 2 and Figure 3 A magnetic plate 4 is installed on the inner wall of the connecting groove 3. The magnetic plate 4 and the magnetic strip 8 are on the same magnetic pole on the side that are close to each other. This allows the repulsive force of the magnetic poles to be used to buffer the vibration force of the reed body 9 from both sides of the damping tube 5. Furthermore, it can be used in conjunction with the buffer spring 6 to reduce the vibration force of the reed body 9 from different directions.
[0032] See Figure 4The wiring board 11 has long slots 13 on both sides. The outer walls of the two brackets 10 are equipped with movable blocks 14. The upper and lower sides of the movable blocks 14 are fixedly connected to one end of the return springs 15. The ends of the two return springs 15 away from the movable blocks 14 are fixedly connected to the inner wall of the long slots 13. The movable blocks 14 are slidably connected to the inside of the long slots 13, so that the wiring board 11 can be stably set on one side of the reed body 9. Furthermore, when the yarn passes through the inner wall of the wiring hole 12, the position of the wiring board 11 can be slightly adjusted by the elastic force of the return springs 15, so as not to cause the yarn to twist. The movable state of the wiring board 11 can ensure the adaptability of the yarn when it is being routed.
[0033] See Figure 5 The adjustment assembly includes a frame 16, a motor 17 mounted on the outer side of the support plate 1, a lead screw 18 fixedly connected to the power output shaft of the motor 17, a slider 19 threadedly connected to the outer edge of the lead screw 18, and an inertial sensor body 20 mounted on the top of the slider 19, so that the motor 17 can drive the lead screw 18 to rotate, thereby causing the slider 19 to slide on the inner wall of the frame 16. The position of the inertial sensor body 20 can be adjusted, and the inertial sensor body 20 can be used to monitor the tilt angle and state of the yarn at different positions.
[0034] See Figure 5 A ring is installed on the inner wall of the frame 16. The end of the lead screw 18 away from the motor 17 is rotatably connected to the inner wall of the ring, which can be used to limit the lead screw 18 during rotation, thereby ensuring the stability of the lead screw 18 during rotation and ensuring that it will not arbitrarily shift or swing in position during rotation.
[0035] See Figure 1 - Figure 4 The position of the thread guide plate 11 corresponds to that of the split reed body 9, so that the thread guide plate 11 and the thread guide hole 12 can be used to pre-sort the yarn before the yarn enters the split reed body 9, making it easier for the yarn to pass through the reed and better maintaining the tension of the yarn.
[0036] Working principle:
[0037] First, the yarn can be passed through the threading hole 12 before entering the reed body 9, which allows for pre-arrangement of the yarn, making it easier to pass through the reed and better maintaining stable yarn tension. The traction force of the yarn passing through the threading hole 12 causes the threading plate 11 to swing up and down, and the moving block 14 can slide up and down inside the long groove 13 to exert a squeezing force on the return spring 15, further adjusting the state of the threading plate 11 to adapt to different yarn directions. Furthermore, when the yarn passes through the reed body 9, the buffer spring 6 can be used to... The buffer force effectively alleviates the force of the reed body 9 during movement, further ensuring the stability of the reed body 9 during yarn feeding, and effectively buffering the vibration force during equipment operation, ensuring that the yarn inside the reed body 9 will not shift and become tangled, and can drive the motor 17 to drive the lead screw 18 to rotate, which in turn can drive the slider 19 to slide on the inner wall of the frame 16, further adjusting the position of the inertial sensor body 20, and thus using the inertial sensor body 20 to monitor the tilt angle and state of the yarn at different positions.
