Description

Technical Field

[0001] This utility model relates to the field of detector technology, and more specifically, to a glass fiber filament breakage detector. Background Technology

[0002] Glass fiber, as a high-performance inorganic non-metallic material, has been widely used in aerospace, wind power generation, automotive lightweighting, building reinforcement, electronics, sports equipment, and many other fields due to its high strength, lightweight, corrosion resistance, good insulation, and strong designability. Its basic form consists of continuous glass monofilaments with diameters ranging from a few micrometers to over twenty micrometers. The core process for modern glass fiber production is the tank furnace drawing method, which involves melting, spinneret forming, high-speed drawing, bundling, and coating processes to finally wind and form the fiber.

[0003] However, during the high-speed, high-temperature, and high-precision fiber drawing process, the accidental breakage (fiber breakage) of single or multiple fibers is an unavoidable problem with serious consequences. If the oiler cannot be lifted in time after a fiber breakage, expensive sizing agent will be sprayed directly onto the equipment or the ground, resulting in waste. Furthermore, the fiber breakage will cause the missing fiber in subsequent bundling, leading to localized thinning and uneven structure of the original fiber bundle. Therefore, the fiber breakage detector is the core monitoring device. However, existing fiber breakage detectors are all fixed between or after the bundler and the oiler. In actual use, as the collecting roller continues to roll, the tension and position of the glass fiber bundle will change. However, the existing fiber breakage detectors cannot move with the changes in the glass fiber bundle, which will lead to inaccurate detection.

[0004] The purpose of this invention is to provide a glass fiber filament breakage detector to solve the problems existing in the prior art. Utility Model Content

[0006] This utility model provides a glass fiber filament breakage detector, comprising:

The universal joint is fixedly connected to the base, the steering part is rotatably connected to the universal joint, and the locking part is located on one side of the steering part and is rotatably connected to the steering part.

[0009] The support mechanism is fixedly connected to the universal joint.

[0010] The pneumatic detection mechanism is locked to the support mechanism.

[0011] Furthermore, the universal joint includes a first universal rod, a first universal ball, a second universal rod, a second universal ball, a first outer ball cage, and a second outer ball cage. One end of the steering part is provided with the first outer ball cage and the second outer ball cage. The first universal rod is fixedly connected to the base. The end of the second universal rod away from the base is fixedly connected to the first universal ball. The first universal ball is located inside the first outer ball cage and is rotatably connected to the first outer ball cage. One end of the second universal rod is fixedly connected to the support mechanism. The end of the second universal rod away from the support mechanism is fixedly connected to the second universal ball. The second universal ball is rotatably connected to the second outer ball cage.

[0012] Furthermore, the steering unit includes a first steering rod, a second steering rod, and a third steering rod. One end of the first steering rod is fixedly connected to the first outer FIBC. The second steering rod is rotatably connected to the first steering rod. The third steering rod is located on the second steering rod and is rotatably connected to the second steering rod. The end of the third steering rod away from the second steering rod is fixedly connected to the second outer FIBC.

[0013] Furthermore, the locking part includes a locking ring and a locking disc. The locking ring is sleeved on the second steering rod and has locking teeth inside. The locking disc is located on one side of the locking ring and is fixedly connected to the locking ring.

[0014] Furthermore, the support mechanism includes a clamping arm, a clamping rod, and a clamping disc. The clamping arm is fixedly connected to the second universal rod. Clamping holes are provided on both sides of the clamping arm. The clamping rod passes through the clamping holes and is rotatably connected to the clamping holes. One end of the clamping rod is fixedly connected to the clamping disc.

[0015] Furthermore, the pneumatic detection mechanism includes a detection box, a nozzle, and a pressure sensor. The detection box is slidably connected to the clamping arm, and a clamping hole is provided at the connection between the detection box and the clamping arm. The clamping hole corresponds to the diameter of the clamping rod.

[0016] Furthermore, a switch assembly is provided on the base, which is used to control the operation of the pneumatic detection mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a stable installation foundation for the entire device through the base, which improves the device's resistance to vibration interference in the operating environment, reduces the impact of external mechanical vibration on detection accuracy, enhances adaptability to ground installation conditions, reduces the risk of detection benchmark deviation caused by uneven foundation, and lays a physical foundation for high-precision detection. The rotational connection between the universal joint and the steering part of the steering mechanism provides multi-degree-of-freedom adjustment capability in three-dimensional space, enabling the pneumatic detection mechanism to make precise position and posture adjustments, ensuring that the detection element, i.e., the nozzle, is always in the optimal working position. The locking mechanism achieves a balance between flexible adjustment and stable locking during operation. Adjustment is easy, and during operation, it prevents accidental displacement caused by equipment operation or external factors, ensuring the reliability of the detection process. As the collecting roller continuously collects the glass fiber bundle, the thickening of the fiber layer causes dynamic changes in the overall trajectory and tension of the fiber bundle. Traditional fixed detectors struggle to adapt to this shift. The steering mechanism allows operators to fine-tune the position of the pneumatic detection mechanism based on the real-time status of the collecting roller, enabling it to dynamically track changes in the fiber bundle's position and adjust the relative distance and angle between the detection point and the fiber bundle. This maintains the optimal spatial relationship between the detection element and the fiber bundle throughout the entire collection cycle, solving the problem of detection accuracy attenuation caused by the collection process and ensuring continuous accuracy in broken fiber detection. The support mechanism connects to the steering mechanism. The bridge connecting the pneumatic detection unit strengthens the overall structural rigidity, and its fixed connection with the steering mechanism forms a stable force transmission path from the base to the detection unit, suppressing potential vibrations of the detection unit itself and ensuring the stability of pneumatic signal acquisition. Simultaneously, the locking connection structure between the pneumatic detection unit and the pneumatic detection mechanism enhances the maintainability and modularity of the equipment, making the assembly and disassembly of the pneumatic detection mechanism more convenient and efficient, shortening the time required for maintenance or replacement. The core advantage of the pneumatic detection mechanism lies in its excellent environmental adaptability and deep adaptation to fiber characteristics. Based on the non-contact detection principle of airflow disturbance, it fundamentally avoids the common problems of dust, wetting agent oil mist, and other contaminants causing shielding, contamination, and failure of optical sensors. The compressed air flow itself also forms a continuous self-cleaning barrier, reducing maintenance requirements and extending the stable operating cycle. In terms of detection performance, the airflow has a significant and direct effect on micron-sized glass fibers, improving the ability to capture minute broken fiber signals. It naturally overcomes the problem of light penetration or reflection recognition that may occur when optical detection is used with transparent or semi-transparent fibers. At the same time, pneumatic signals are relatively less affected by common background noise on the production line, namely equipment mechanical vibration and electromagnetic interference, ensuring the effectiveness and reliability of the signal.

[0027] See Figure 1-3 As shown, this embodiment provides a glass fiber filament breakage detector, including:

[0028] Base 1.

[0029] Steering mechanism 2 includes a universal joint, a locking part and a steering part. The universal joint is fixedly connected to the base 1, the steering part is rotatably connected to the universal joint, and the locking part is located on one side of the steering part and is rotatably connected to the steering part.

[0030] Support mechanism 3 is fixedly connected to the universal joint.

[0031] The pneumatic detection mechanism 4 is locked to the support mechanism 3.

[0032] Specifically, the base 1 is located between the bundler and the oiler. The glass fiber bundle passes through the pneumatic detection mechanism 4. The pneumatic detection mechanism 4 blows a stable low-pressure, low-flow compressed air jet into the glass fiber bundle that passes through it. Behind the glass fiber bundle, that is, at the position directly opposite the nozzle 402 (usually a few millimeters to a dozen millimeters apart), a pressure sensor 403 is installed. The sensor detects whether there is any broken fiber by blowing air into the glass fiber bundle. During normal operation, the fiber bundle blocks the air jet blown out by the nozzle 402, preventing it from directly impacting the sensor on the opposite side. When the airflow is disturbed, deflected, or absorbed by the fiber bundle, the airflow pressure / flow rate signal received by the sensor is weak and stable. When a fiber breaks, a gap appears at that location or the fiber bundle position shifts. The air jet blown out by the nozzle 402 can partially or completely pass through the gap and directly impact the sensor on the opposite side. The sensor detects a sudden increase in airflow pressure / flow rate / impact force. This abrupt signal is identified as a fiber breakage event, and an alarm is output. The steering mechanism 2 can control the pneumatic detection mechanism 4 to make fine adjustments to its position. As the collecting roller continues to collect the glass fiber bundle, the glass fiber bundle on the collecting roller will become thicker and thicker. At this time, the glass fiber bundle will undergo changes in tension and position. The steering mechanism 2 adjusts the position of the pneumatic detection mechanism 4 so that it can more accurately detect whether there is a fiber breakage. The support mechanism 3 is used to connect the pneumatic detection mechanism 4. The pneumatic detection mechanism 4 and the support mechanism 3 are locked together, which makes it easier to repair or replace when needed. The steering mechanism 2 achieves steering through the universal joint, and the locking part can lock the universal joint to prevent it from rotating on its own.

[0033] Understandably, base 1 provides a solid installation foundation for the overall structure. Its stable support characteristics enhance the equipment's resistance to vibration interference during continuous operation and reduce the impact of external mechanical vibration on detection accuracy. Simultaneously, base 1 improves adaptability to ground installation conditions, reducing the risk of detection benchmark shift due to slight unevenness of the foundation, creating a stable physical environment for high-precision detection. Steering mechanism 2 achieves unique dynamic adjustment value through multi-component collaborative design. The fixed connection between the universal joint and base 1 ensures the reliability of initial positioning, while the rotational cooperation between the universal joint and steering mechanism gives the pneumatic detection mechanism 4 flexible adjustment capabilities in three-dimensional space. The dual-state working mode of the locking part (easy rotation during adjustment, stable locking during operation) ensures both the convenience of fine-tuning operations and eliminates spontaneous displacement that may occur during equipment operation. The core advantage of this mechanism lies in solving the problem of fiber bundle shift caused by the thickening of the collection roller: as the number of winding layers of the collection roller increases, the running trajectory and tension distribution of the glass fiber bundle continuously change. Traditional fixed detectors cannot adapt to this dynamic shift, resulting in decreased detection sensitivity. The steering mechanism 2 allows operators to precisely adjust the horizontal position, vertical height, and nozzle 402 tilt angle of the pneumatic detection mechanism 4 according to real-time operating conditions, ensuring it continuously tracks the displacement trajectory of the fiber bundle and maintains the optimal interaction between the airflow and the fiber bundle. This guarantees the accuracy of the detection throughout the entire production cycle. The support mechanism 3, as the connection hub between the steering mechanism 2 and the pneumatic detection unit, enhances the stability of the force transmission path. Its fixed connection with the steering mechanism 2 forms a fixed support frame, suppressing the micro-vibrations caused by airflow reaction or equipment vibration in the pneumatic detection unit, reducing signal noise interference. Simultaneously, the locking connection mode between the support mechanism 3 and the pneumatic detection mechanism 4 significantly improves the maintainability of the equipment, making the disassembly and installation of the detection unit more efficient and faster, shortening downtime for maintenance operations, and avoiding positioning accuracy loss caused by repeated disassembly and assembly. The core advantage of the pneumatic detection mechanism 4 stems from its non-contact detection principle and high environmental adaptability. By spraying low-pressure, stable airflow into the running glass fiber bundle and monitoring the pressure change after the airflow passes through the fiber bundle, this mechanism avoids the inherent defects of traditional detection methods. Its working process is naturally resistant to contaminants such as dust and wetting agent mist—the airflow itself forms a continuous self-cleaning barrier, avoiding the risk of mirror contamination failure common in optical sensors. In terms of detection performance, the airflow has a more direct and sensitive physical response to micron-sized fibers, improving the ability to identify single-filament breaks. Its principle is unaffected by the transparency of fibers, overcoming the inherent problem of signal attenuation in transparent media in optical detection. Simultaneously, the pneumatic signal has stronger anti-interference capabilities against background mechanical vibrations and electromagnetic noise from the production line, ensuring the reliability of signal capture. When a fiber bundle breaks, the abrupt change in the airflow path generates a distinct characteristic signal, which can quickly trigger a precise alarm.

[0034] In some embodiments of this application, the universal joint includes a first universal rod 201, a first universal ball 202, a second universal rod 203, a second universal ball 204, a first outer ball cage 205, and a second outer ball cage 206. One end of the steering part is provided with the first outer ball cage 205 and the second outer ball cage 206. The first universal rod 201 is fixedly connected to the base 1. The end of the second universal rod 203 away from the base 1 is fixedly connected to the first universal ball 202. The first universal ball 202 is located inside the first outer ball cage 205 and is rotatably connected to the first outer ball cage 205. One end of the second universal rod 203 is fixedly connected to the support mechanism 3. The end of the second universal rod 203 away from the support mechanism 3 is fixedly connected to the second universal ball 204. The second universal ball 204 is rotatably connected to the second outer ball cage 206.

[0035] In some embodiments of this application, the steering unit includes a first steering rod 207, a second steering rod 208, and a third steering rod 209. One end of the first steering rod 207 is fixedly connected to the first outer CV joint 205. The second steering rod 208 is rotatably connected to the first steering rod 207. The third steering rod 209 is located on the second steering rod 208 and is rotatably connected to the second steering rod 208. One end of the third steering rod 209 away from the second steering rod 208 is fixedly connected to the second outer CV joint 206.

[0036] Specifically, the position of the steering rod is changed by rotating the omnidirectional ball inside the outer ball cage, and the rotational connection between the first steering rod 207 and the third steering rod 209 and the second steering rod 208 can achieve the effect of axial rotation.

[0037] Understandably, the composite rotational structure of the dual universal joints and the outer ball cage enhances the freedom and stability of spatial posture adjustment. The rotational connection between the first universal joint 202 and the first outer ball cage 205, combined with the rotational connection between the second universal joint 204 and the second outer ball cage 206, forms two independent rotational pivots in three-dimensional space. This allows the motion trajectory at the end of the support mechanism 3 to break through the limitations of a single-point universal joint, enabling large-angle pitch and yaw adjustments while suppressing the risk of mechanical interference caused by excessive rotation of a single joint. The outer ball cage's enveloping constraint on the universal joints enhances the joint's resistance to dust contamination, reduces the probability of jamming caused by external foreign object intrusion, and simultaneously disperses load stress, extending the durability of moving parts. The three-stage steering linkage structure constructs a pose transfer chain through the superposition of multiple degrees of freedom. The fixed connection between the first steering rod 207 and the first outer ball cage 205 establishes the initial reference, and its rotational cooperation with the second steering rod 208 provides axial torsional freedom. The rotational connection between the third steering rod 209 and the second steering rod 208 introduces radial swing freedom. This allows the operator to achieve complex pose adjustment of the pneumatic detection mechanism 4 in space through a single action (such as rotating or moving a specific rod). The three-bar series topology naturally suppresses the lever arm amplification effect of traditional single-bar adjustment, reduces operational jitter during fine-tuning, and improves positioning accuracy. The mechanical coordination of the universal joint and the steering unit solves the core contradiction in the dynamic production environment: the need for fine adjustment. The double universal ball joint structure supports 4 mm-level displacement fine-tuning and milliradian-level angle calibration of the pneumatic detection mechanism, ensuring that the distance and tilt angle between the nozzle 402 and the fiber bundle are always within the optimal detection range. Anti-offset stability: The outer ball cage's enveloping constraint on the omnidirectional ball, combined with the rigid connection between the rods, forms a truss-like structure in the locked state, resisting the interference of continuous tension changes in the fiber bundle caused by the thickening of the collecting roller on the detection position.

[0038] In some embodiments of this application, the locking part includes a locking ring 210 and a locking disc 211. The locking ring 210 is sleeved on the second steering rod 208 and has locking teeth inside. The locking disc 211 is located on one side of the locking ring 210 and is fixedly connected to the locking ring 210.

[0039] In some embodiments of this application, the support mechanism 3 includes a clamping arm 301, a clamping rod 302, and a clamping disc 303. The clamping arm 301 is fixedly connected to the second universal rod 203. Clamping holes are provided on both sides of the clamping arm 301. The clamping rod 302 passes through the clamping hole and is rotatably connected to the clamping hole. One end of the clamping rod 302 is fixedly connected to the clamping disc 303.

[0040] Specifically, the locking part is used to lock the axial rotation capability of the third steering rod 209. The third steering rod 209 is sleeved on the second steering rod 208, and one end of the sleeved part is provided with an annular protrusion. The diameter of the locking ring 210 is slightly larger than the annular protrusion. By rotating the locking disc 211, the locking ring 210 is rotated in the direction of the annular protrusion. Then, the locking teeth in the locking ring 210 lock the annular protrusion, thereby preventing the third steering rod 209 from rotating. The third steering rod 209 is connected to a clamping arm 301, which is used to clamp the pneumatic detection mechanism 4. By rotating the clamping disc 303, the clamping rod can be moved, thereby controlling the two ends of the clamping arm 301 to move inward, realizing the function of locking the pneumatic detection mechanism 4. When it is necessary to replace or repair the pneumatic detection function, simply rotate and open the clamping rod 302 to remove the pneumatic detection mechanism 4.

[0041] Understandably, the locking mechanism of the toothed engagement surface of the locking part improves the reliability of the position fixation. The engagement of the locking teeth inside the locking ring 210 with the annular protrusion of the third steering rod 209 overcomes the limitations of force transmission in traditional friction locking. When the rotating locking disc 211 drives the locking ring 210 to press against the annular protrusion, the locking teeth embed into the surface of the protrusion to form a multi-point mechanical interlock. The retaining force is converted from surface friction to inter-tooth engagement, resisting the interference of continuous fiber bundle tension changes caused by the thickening of the collecting roller on the position of the detection mechanism.

[0042] In some embodiments of this application, the pneumatic detection mechanism 4 includes a detection box 401, a nozzle 402 and a pressure sensor 403. The detection box 401 is slidably connected to the clamping arm 301. A clamping hole is provided at the connection between the detection box 401 and the clamping arm 301. The diameter of the clamping hole corresponds to that of the clamping rod 302.

[0043] In some embodiments of this application, a switch assembly 101 is provided on the base 1, which is used to control the operation of the pneumatic detection mechanism 4.

[0044] Understandably, the sliding connection structure between the detection box 401 and the clamping arm 301 optimizes the equipment maintenance process. Its clamping holes and clamping rod 302 create a physical guiding position, automatically guiding the detection box 401 to the predetermined working position during installation, eliminating positioning deviations caused by manual alignment. The sliding track constrains the lateral freedom of the detection box 401, ensuring its stability under changes in airflow or equipment vibration, reducing the risk of fluctuations in the fiber bundle spacing of the nozzle 402 due to micro-displacement. Simultaneously, maintenance personnel can quickly replace and start the detection mechanism along a fixed trajectory, avoiding operational interference in confined spaces caused by traditional bolt fixing methods. The coaxial arrangement of the nozzle 402 and the pressure sensor 403 within the detection box 401 is the core structure ensuring pneumatic detection accuracy. Pressure changes after airflow passes through the fiber bundle can be transmitted to the sensor, eliminating the pressure response lag and signal attenuation caused by hose connections in traditional split structures. The closed flow channel isolates external airflow disturbances (such as workshop ventilation and airflow caused by personnel movement), enhancing the recognition of micro-pressure difference signals.

[0045] In the above embodiments, the fiberglass filament breakage detector provides a stable installation foundation for the entire device through the base 1, which improves the device's resistance to vibration interference in the operating environment, reduces the impact of external mechanical vibration on detection accuracy, enhances adaptability to ground installation conditions, reduces the risk of detection benchmark deviation caused by uneven foundation, and lays a physical foundation for high-precision detection. The rotational connection between the universal joint and the steering joint of the steering mechanism 2 provides multi-degree-of-freedom adjustment capability in three-dimensional space, enabling the pneumatic detection mechanism 4 to perform precise position and posture adjustment, ensuring that the detection element, i.e., the nozzle 402, is always in the optimal working position. The locking mechanism achieves a balance between flexible adjustment and stable locking during operation. It allows for easy adjustment and prevents accidental displacement due to equipment operation or external factors, ensuring the reliability of the detection process. As the collecting roller continuously collects the glass fiber bundle, the thickening of the fiber layer causes dynamic changes in the overall trajectory and tension of the fiber bundle. Traditional fixed detectors struggle to adapt to this shift. The steering mechanism 2 allows operators to fine-tune the position of the pneumatic detection mechanism 4 based on the real-time status of the collecting roller, enabling it to dynamically track the positional changes of the fiber bundle and adjust the relative distance and angle between the detection point and the fiber bundle. This maintains the optimal spatial relationship between the detection element and the fiber bundle throughout the entire collection cycle, solving the problem of detection accuracy attenuation caused by the collection process and ensuring the continuous accuracy of broken fiber detection. The support mechanism 3 connects the steering mechanism 2 and... The bridge of the pneumatic detection unit strengthens the rigidity of the overall structure. Its fixed connection with the steering mechanism 2 forms a stable force transmission path from the base 1 to the detection unit, suppressing the vibration that the detection unit itself may generate and ensuring the stability of pneumatic signal acquisition. At the same time, the locking connection structure adopted between it and the pneumatic detection mechanism 4 improves the maintainability and modularity of the equipment, making the disassembly and assembly of the pneumatic detection mechanism 4 more convenient and efficient, and shortening the time required for maintenance or replacement. The core advantage of the pneumatic detection mechanism 4 lies in its excellent environmental adaptability and deep adaptation to fiber characteristics. Based on the non-contact detection principle of airflow disturbance, it fundamentally avoids the common problems of dust, wetting agent oil mist and other pollutants causing shielding and contamination failure of optical sensors. The compressed air flow itself also forms a continuous self-cleaning barrier, reducing maintenance requirements and extending the stable operation cycle. In terms of detection performance, the airflow has a significant and direct effect on micron-sized glass fibers, improving the ability to capture minute broken fiber signals. It naturally overcomes the problem of light penetration or reflection recognition that may occur when optical detection is used with transparent or semi-transparent fibers. At the same time, pneumatic signals are relatively less affected by common background noise on the production line, namely equipment mechanical vibration and electromagnetic interference, ensuring the effectiveness and reliability of the signal.
