Description

Technical Field

[0001] This application relates to the field of yarn breakage detectors, and more particularly to a yarn breakage self-stop detector. Background Technology

[0002] Yarn breakage detectors are automated devices used in the textile industry for real-time monitoring of yarn breakage. They primarily use photoelectric or pressure sensing technology to identify yarn breakage and trigger a shutdown protection mechanism. Their core principles include infrared / laser beam path interruption detection or tension change sensing, combined with a signal processing system to achieve immediate alarms and automatic equipment shutdown. Widely used in textile machinery such as sewing machines and winding machines, they typically have a response time of up to 1 second and a detection accuracy of ±1mm. In conventional yarn breakage self-stop detectors, a connector is inserted into the detection sensor, facilitating power connection to the sensor and control equipment. The sensor has an internal detection port; the yarn is installed on the inner wall of the port. The detector emits infrared light to detect the yarn breakage and triggers an alarm when a breakage occurs, allowing for timely intervention by staff.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional yarn breakage self-stop detectors, in actual use, are easily affected by the yarn tension and installation position, resulting in the yarn being too close or too far from the sensor. This affects the detection effect of the yarn breakage self-stop detector, and the contact with the sensor can easily cause wear on the surface of the yarn, affecting the quality of the yarn.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The yarn breakage self-stop detector provided in this application adopts the following technical solution: A yarn breakage self-stop detector includes a detection sensor and a mounting frame. The detection sensor has a detection port on its surface and a connector is snapped onto its bottom end. The center of the connector is on the same straight line as the center of the detection sensor. An upper detection frame and a lower detection frame are slidably mounted on the inner wall of the mounting frame. A support spring is fixedly connected to one end of each of the upper and lower detection frames. A pressure sensor is fixedly connected to one end of each support spring. One end of the mounting frame is slidably mounted on the surface of the detection sensor, and the cross-section of the mounting frame is L-shaped. One end of the pressure sensor is fixedly connected to the inner wall of the mounting frame. The cross-sections of both the upper and lower detection frames are U-shaped.

[0007] Preferably, the center of the support spring is on the same straight line as the center of the pressure sensor, and the two support springs are symmetrically distributed about the mounting bracket.

[0008] Preferably, pulleys are rotatably installed on the inner walls of both the upper and lower inspection frames, and the dimensions of the pulley surfaces are adapted to the dimensions of the inner walls of the upper inspection frame.

[0010] Preferably, two electric push rods are fixedly connected to the top of the mounting bracket. One end of each electric push rod is fixedly mounted to the surface of the detection sensor. The two electric push rods are symmetrically distributed about the detection sensor, and one end of each electric push rod is electrically connected to one end of the pressure sensor via a wire.

[0011] Preferably, one end of the detection sensor is fixedly connected to two fixing frames, the two fixing frames are symmetrically distributed about the detection sensor axis, and a sliding frame is slidably installed on the inner wall of the fixing frame, one end of the sliding frame is fixedly connected to the surface of the mounting frame.

The two groups of auxiliary wheels are symmetrically distributed about the mounting frame, and the surfaces of the auxiliary wheels are slidably connected to the inner wall of the fixed frame.

[0013] In summary, this application includes the following beneficial technical effects: 1. By connecting the mounting frame to the surface of the detection sensor, an upper and lower detection frame are slidably mounted on the inner wall of the mounting frame. Each end of the upper and lower detection frames is connected to a pressure sensor via a support spring, allowing for the detection of yarn position. This facilitates easy adjustment of the sensor height by the operator.

Pulleys are rotatably mounted on the inner walls of both frames to reduce friction between the frames and the yarn. A slider is fixedly mounted on one end of each frame to improve stability. Compared to existing technologies, this significantly improves the performance of the yarn breakage detector. 2. Two electric push rods can also be installed on the top of the mounting frame. After the pressure sensor detects the yarn position, the electric push rods can be used to move the detection sensor to a suitable position. One end of the detection sensor is fixedly connected to two fixed frames.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses a yarn breakage self-stop detector, referring to... Figure 1 - Figure 2 The system includes a detection sensor 1. During use, a connector 3 is inserted into the detection sensor 1, allowing for easy connection to power and control equipment. The detection sensor 1 has a detection port 2. Yarn is installed on the inner wall of the detection port 2. An infrared detector emits infrared light to detect the yarn breakage and triggers an alarm when a yarn breakage occurs, facilitating timely intervention by staff. A mounting frame 4 is connected to the surface of the detection sensor 1. An upper detection frame 7 and a lower detection frame 8 are slidably mounted on the inner wall of the mounting frame 4. A support spring 6 is fixedly connected to one end of each of the upper and lower detection frames 7 and 8. A pressure sensor 5 is fixedly connected to one end of each support spring 6. When the yarn deviates, it contacts the upper and lower detection frames 7 and 8, and the pressure sensor 5 detects the yarn position, allowing staff to easily adjust the height of the detection sensor 1, effectively improving the performance of the yarn breakage detector.

[0018] Reference Figure 2Support springs 6 are fixedly installed at one end of the upper detection frame 7 and the lower detection frame 8. The support springs 6 push the upper detection frame 7 and the lower detection frame 8 to keep them connected to the periphery of the detection port 2, effectively ensuring the detection effect of the upper detection frame 7 and the lower detection frame 8. The inner walls of the upper detection frame 7 and the lower detection frame 8 are rotatably installed with pulleys 9. The surface of the pulleys 9 is slidably connected to the surface of the yarn. The pulleys 9 reduce the friction between the upper detection frame 7 and the lower detection frame 8 and the yarn, thereby preventing the problem of yarn damage caused by friction between the upper detection frame 7 and the lower detection frame 8 and the yarn. The upper detection frame 7 and the lower detection frame 8 are fixedly installed at one end of the upper detection frame 7 and the lower detection frame 8. The surface of the slider 10 is slidably connected to the inner wall of the mounting frame 4. The slider 10 restricts the movement position of the upper detection frame 7 and the lower detection frame 8, effectively improving the stability of the upper detection frame 7 and the lower detection frame 8.

[0019] Reference Figure 3 - Figure 4 Two electric push rods 11 are installed on the top of the mounting frame 4. The two electric push rods 11 are synchronous push rods, which can realize synchronous operation on both sides. One end of the electric push rod 11 is fixedly connected to the surface of the detection sensor 1, and the other end of the electric push rod 11 is electrically connected to one end of the pressure sensor 5 through a wire. After the pressure sensor 5 detects the yarn position, the electric push rod 11 controls its own length and moves the detection sensor 1 to a suitable position, which effectively reduces the amount of manual operation. Two fixed frames 12 are fixedly connected to one end of the detection sensor 1. A sliding frame 13 is slidably installed on the inner wall of the fixed frame 12. One end of the sliding frame 13 is welded to the surface of the mounting frame 4. The fixed frame 12 and the sliding frame 13 restrict the movement position of the detection sensor 1, thereby ensuring the stability of the movement of the detection sensor 1. Several auxiliary wheels 14 are rotatably installed on the inner wall of the sliding frame 13. The surface of the auxiliary wheels 14 is slidably connected to the inner wall of the fixed frame 12. The auxiliary wheels 14 reduce the friction between the sliding frame 13 and the fixed frame 12, making the movement of the detection sensor 1 more stable.

[0020] The implementation principle of the yarn breakage self-stop detector in this application embodiment is as follows: The mounting frame 4 is connected to the surface of the detection sensor 1. An upper detection frame 7 and a lower detection frame 8 are slidably mounted on the inner wall of the mounting frame 4. A support spring 6 is fixedly connected to one end of each of the upper and lower detection frames 7 and 8. A pressure sensor 5 is fixedly connected to one end of each support spring 6, so that it can contact the upper and lower detection frames 7 and 8 when the yarn deviates, and detect the position of the yarn through the pressure sensor 5. This facilitates the worker's adjustment of the height of the detection sensor 1. The support spring 6 is fixedly mounted to one end of each of the upper and lower detection frames 7 and 8, so that the upper and lower detection frames 7 and 8 can be pushed by the support spring 6. The upper and lower inspection frames 7 and 8 are connected to the periphery of the inspection port 2, effectively ensuring the inspection effect of the upper and lower inspection frames 7 and 8. The inner walls of the upper and lower inspection frames 7 and 8 are rotatably equipped with pulleys 9. The surface of the pulleys 9 is slidably connected to the surface of the yarn, so as to reduce the friction between the upper and lower inspection frames 7 and 8 and the yarn, thereby preventing the problem of yarn damage caused by friction between the upper and lower inspection frames 8 and the yarn. A slider 10 is fixedly installed at one end of the upper and lower inspection frames 7 and 8. The surface of the slider 10 is slidably connected to the inner wall of the mounting frame 4, so as to restrict the movement position of the upper and lower inspection frames 7 and 8, effectively improving the stability of the upper and lower inspection frames 7 and 8.

[0021] Two electric push rods 11 can also be installed on the top of the mounting frame 4. The two electric push rods 11 are synchronous push rods, which can realize synchronous operation on both sides. One end of the electric push rod 11 is fixedly connected to the surface of the detection sensor 1, and the other end of the electric push rod 11 is electrically connected to one end of the pressure sensor 5 through a wire. After the pressure sensor 5 detects the yarn position, the electric push rod 11 controls its own length and moves the detection sensor 1 to a suitable position, which effectively reduces the amount of manual operation. Two fixed frames 12 are fixedly connected to one end of the detection sensor 1. A sliding frame 13 is slidably installed on the inner wall of the fixed frame 12. One end of the sliding frame 13 is welded to the surface of the mounting frame 4. The fixed frame 12 and the sliding frame 13 restrict the movement position of the detection sensor 1, thereby ensuring the stability of the movement of the detection sensor 1. Several auxiliary wheels 14 are rotatably installed on the inner wall of the sliding frame 13. The surface of the auxiliary wheels 14 is slidably connected to the inner wall of the fixed frame 12. The auxiliary wheels 14 reduce the friction between the sliding frame 13 and the fixed frame 12, making the movement of the detection sensor 1 more stable.
