Description

Technical Field

[0001] This utility model belongs to the field of stranding machine technology, specifically relating to an intelligent alarm device for single wire allowance and wire breakage in stranding equipment. Background Technology

[0002] Traditional stranding machine alarm systems primarily determine whether to trigger an alarm by detecting the rotation status of the monofilament reel. The principle is that when the monofilament reel stops rotating, the system determines that the monofilament is exhausted or broken, thereby triggering an alarm. However, this method has the following drawbacks: to avoid false alarms, a certain linear speed is required for a response. But in the production process, sometimes the speed is lower than the corresponding speed in order to maintain stable production, which causes the alarm function to fail. The existing technology has the following defects and shortcomings: High false alarm rate: During the production process, the line speed may be lower than the threshold due to process requirements, which may cause the system to fail to respond or make false judgments. Delayed alarm: The alarm function can only be activated after the set linear speed is reached, and the status of the single filament cannot be monitored in real time; Poor stability: The alarm function fails when running at low speeds, affecting production safety and continuity. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: A smart alarm device for single wire excess and wire breakage in stranding equipment, comprising: Several sets of intelligent alarm mechanisms are installed on one side of the splitter board body. The splitter board body is located between the equipment auger and the mold and is used for splitting the wires. The several sets of intelligent alarm mechanisms are distributed in a circular array on one side of the splitter board body. The intelligent alarm mechanism includes a mounting component, an adjustable component, and a pressure sensing device. The mounting component is located on one side of the branch board body. The pressure sensing device is mounted on the mounting component via the adjustable component. The pressure sensing device is in contact with the monofilament contact surface and is used to detect the pressure value generated by the monofilament tension in real time. In conjunction with the signal processing module, the pressure fluctuation frequency and absolute value are judged by dual thresholds to realize insufficient margin warning and immediate alarm for wire breakage. The adjustable component can adjust the position of the pressure sensing device, making it highly versatile.

[0005] Preferably, the adjustable component includes a support frame, an adjusting bolt, and a guide wheel.

The intelligent alarm mechanism 20 includes a mounting component, an adjustable component, and a pressure sensing device. The mounting component is provided on one side of the branch board body 10. The pressure sensing device is installed on the mounting component through the adjustable component. The pressure sensing device is in contact with the monofilament and is used to detect the pressure value generated by the tension of the monofilament in real time. In conjunction with the signal processing module 30, the pressure fluctuation frequency and absolute value are judged by dual thresholds to realize the early warning of insufficient margin and the immediate alarm of wire breakage. The adjustable component can adjust the position of the pressure sensing device, which has high versatility.

Two sets of support frames 22 are respectively set on both sides of the mounting plate 25. The inside of the branch plate body 10 is provided with a threaded hole that mates with the threaded rod 24. The other end of the threaded rod 24 is threaded with a nut. The cooperation between the threaded rod 24 and the nut makes the intelligent alarm mechanism 20 easy to install or disassemble and simple to operate.

[0017] refer to Figures 1-3 As shown, the pressure sensing device is set as a pressure sensor 21.

[0018] refer to Figures 1-3 As shown, a number of branch plate guide wheels 11 are also installed on one side of the branch plate body 10. The number of branch plate guide wheels 11 corresponds to the number of intelligent alarm mechanisms 20. When the wire is running, the single wire first passes through the corresponding branch plate guide wheel 11 and then passes through the surface of the pressure sensor 21 of the intelligent alarm mechanism 20, so that the pressure sensor 21 can detect the pressure value generated by the tension of the single wire.

[0020] This application sets out: Signal processing module: Receives pressure sensor signals and has built-in threshold judgment logic; Balance alarm threshold: Set the pressure fluctuation range (e.g., ±10% of the rated value). When the fluctuation frequency exceeds the set value (e.g., 3 times / second), an alarm is triggered. Disconnection alarm threshold: An alarm is triggered immediately when the pressure value drops to 0 or close to 0; It also includes a power module: to power the sensors and processing modules, supporting 24V DC or 220V AC input.

[0022] The dynamic operation process, usage method, specific process steps, and process parameters created in this application are as follows: Balance alarm: When the monofilament allowance is insufficient, the pressure value fluctuates periodically due to unstable tension (e.g., 5-8Hz).

[0023] The processing module detects that the fluctuation frequency exceeds the set threshold (e.g., 3Hz for 5 seconds), triggers an audible and visual alarm, and sends a warning signal to the host computer.

[0024] Disconnection alarm: When a single filament breaks, the pressure sensor reading drops sharply to 0 or close to 0.

[0025] The processing module immediately triggers the highest priority alarm and locks the alarm status until manually reset.

During production, the pressure sensor monitors the pressure value generated by the tension of the monofilament in real time and transmits the data to the signal processing module; When abnormal situations such as insufficient monofilament or broken thread occur, the alarm module will promptly issue corresponding alarm signals based on the preset threshold judgment logic, and the operator will take corresponding measures to handle the situation according to the alarm prompts. Regularly inspect and maintain the device, including cleaning the pressure sensor surface and checking the wiring connections, to ensure that the device is always in good working order.
