Description

Technical Field

[0001] The present invention relates to the technical field of air-spinning textiles, and more particularly to a fiber feeding uniformity assurance and fault warning device for air-spinning equipment. Background Art

[0002] In the textile industry, air-spinning equipment, with its advantages of high spinning efficiency and short process steps, is widely used in the processing and production of various fiber materials. Fiber feed uniformity is a key factor affecting the quality of air-spun products, directly impacting core performance indicators such as yarn strength and evenness. Uneven fiber thickness and large fluctuations in thickness during the feeding process can lead to yarn defects such as thin and thick sections, reducing the yield of finished products and increasing the waste of raw materials. It can also increase wear on equipment components and shorten equipment life.

[0003] At present, the fiber feeding process of traditional air-spinning equipment mostly relies on manual inspection or simple mechanical control, and lacks real-time and accurate detection of key parameters such as fiber thickness and coarseness. In terms of fault warning, the equipment can often only be shut down for maintenance after an obvious fault occurs, and potential problems cannot be predicted in advance, resulting in a long production interruption time and causing large economic losses. In addition, the response speed of existing detection devices is slow, and it is difficult to match high-speed air-spinning equipment, and the analysis and processing capabilities of detection data are limited. It is impossible to adjust the feeding parameters in real time according to the fiber status, and it is difficult to meet the requirements of modern textile production for high efficiency, high quality and stability. Therefore, in order to solve the above problems. The existence of a fiber feeding uniformity assurance and fault warning device for air-spinning equipment is crucial. Summary of the Invention

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] Through the coordinated linkage of the thickness detection mechanism, uniform feeding mechanism, coarseness detection mechanism, drive mechanism, and monitoring and early warning system, a complete fiber feeding quality control and fault prevention system has been formed. Overall, it not only significantly improves the uniformity of fiber feeding and ensures the stable quality of spinning products, but also enables real-time monitoring of equipment operating status and accurate early warning, reducing the occurrence of failures and production losses, while optimizing operating procedures and improving production efficiency and management level.

[0018] The thickness detection mechanism monitors the thickness of the textile thread on the collection roller in real time, while the thickness detection mechanism precisely controls changes in the thickness of the textile thread. Both transmit data in real time to the monitoring and early warning system. The system uses the drive control module to instantly adjust the operating parameters of the uniform feeding mechanism and the drive mechanism. For example, if the thickness of the textile thread deviates, the stepper motor can quickly drive the guide tube to fine-tune and compensate for tension deviations. The linkage response is fast and accurate, effectively avoiding yarn defects caused by uneven feeding and significantly improving the qualified rate of finished products.

[0019] The monitoring and early warning system, through the collaboration of multiple modules, can collect and analyze various types of test data at high frequency. Combined with a three-level early warning mechanism, it can issue different levels of warnings based on the degree of deviation. Minor deviations only prompt a warning, while severe deviations immediately reduce speed. At the same time, the remote early warning unit notifies management personnel, enabling full control of the entire process from potential fault prediction to emergency response. This reduces the number of sudden equipment downtimes and minimizes production losses caused by failures.

[0020] The data analysis module's adaptive learning unit optimizes standard thresholds based on long-term operational data, adapting the device to the production needs of different fiber types. Historical data query and export functions facilitate management personnel to trace production processes and analyze quality issues. The parameter setting module allows operators to quickly adjust parameters based on production needs. This overall improvement in the device's intelligence and production management efficiency provides strong support for modern textile production. BRIEF DESCRIPTION OF THE DRAWINGS

By utilizing the coordination of the first fixed plate 2, the slide rod 20 and other components, the position of the guide tube 22 is accurately adjusted by the stepper motor 23 to ensure uniform feeding of the textile thread 16 and reduce defective products caused by feeding deviation.

[0038] Specifically, the thickness detection mechanism includes four second fixing plates 3 fixedly arranged on both sides of the interior of the fixing frame 13. The four second fixing plates 3 are symmetrically arranged on both sides of the interior of the fixing frame 13, and are respectively located on one side of the bottom of the two uniform feeding mechanisms. A fixing rod 30 is fixedly arranged between the two symmetrically arranged second fixing plates 3, and a detection box 31 is fixedly arranged through the fixing rod 30. Inlet and outlet pipes 32 are fixedly arranged on both sides of the two detection boxes 31. The two textile threads 16 pass through the inside of the two detection boxes 31 through the inlet and outlet pipes 32 respectively. The inside of the two detection boxes 31 is uniform.

[0040] Specifically, the fixing mechanism includes four fourth fixing plates 6 respectively fixedly provided on one side of the four first fixing plates 2, the four fourth fixing plates 6 are symmetrically arranged in pairs, and are respectively located on one side of the bottom of the two collecting rollers 42, two guide rollers 60 are rotatably provided between the two symmetrically arranged fourth fixing plates 6, the textile line 16 slides through between the two guide rollers 60, and two mounting plates 61 are fixedly provided between the two symmetrically arranged fourth fixing plates 6.

[0044] Specifically, the monitoring and early warning system includes a central processing module, which is electrically connected to a data acquisition module, a data analysis module, a parameter setting module, an early warning module, and a drive control module.

The module then associates the timestamp of the collected data with the winding position of the textile thread 16 on the collection roller 42 via an encoder and stores the data. The parameter setting module uses control buttons 11 to preset the standard thickness range, standard thickness range, uniform feeding position deviation threshold, and normal speed range of the drive mechanism for the textile thread 16. These preset parameters are stored in the central processing module's storage unit. The drive control module is electrically connected to the first drive motor 5, the second drive motor 50, and the stepper motor 23. When the real-time data exceeds the preset threshold but does not reach the emergency stop threshold, it can adjust the operating parameters of each motor to correct the feeding status, and the linkage response time with the uniform feeding mechanism does not exceed 0.5 seconds. When the thickness deviation of the textile thread 16 exceeds the standard threshold of 5%, the speed of the stepper motor 23 can be adjusted to make the guide tube 22 reciprocate along the slide rod 20 to fine-tune and compensate for the tension deviation.

[0045] The central processing module of the monitoring and early warning system coordinates various modules, the data acquisition module collects data from angle sensors, distance sensors, etc., the parameter setting module presets the standard through the control button 11, and the drive control module adjusts the first drive motor 5, the second drive motor 50 and the stepper motor 23 to correct the feeding status.

The linkage response is fast, and the feeding deviation of the textile thread 16 can be corrected in time to ensure feeding uniformity.

[0046] Specifically, after receiving real-time data from the data acquisition module, the data analysis module compares and analyzes it with the standard threshold value of the parameter setting module, calculating the deviation value and change trend. It has an internal adaptive learning unit that can automatically optimize the floating range of the standard threshold value based on normal operating data, and the optimized threshold value can be manually modified through the parameter setting module. The central processing module is also electrically connected to the historical data query module. By operating the control button 11, historical detection data, fault records, and warning processing results can be queried by time interval on the display screen 12, and data export is supported;

[0047] The data analysis module compares real-time data with standard thresholds, the adaptive learning unit optimizes thresholds, and the historical data query module realizes data query and export through the control button 11 and the display screen 12, thereby improving the adaptability of data processing. The optimized threshold is more in line with reality. The historical data function facilitates the tracing of the production process, provides support for process improvement, and improves management efficiency.

[0048] Specifically, the early warning module includes an audible and visual alarm unit, a display unit 12, and a remote early warning unit. When the data analysis module determines that the real-time data exceeds the preset threshold, the central processing module controls the audible and visual alarm unit to send a signal, and the display 12 displays the fault type, location, and data deviation information; the remote early warning unit connects to the administrator's mobile terminal through the wireless communication module, and when a level 2 or higher early warning is triggered, it automatically sends a text message or APP push notification containing the fault information;

[0049] The sound and light alarm unit, display screen 12 and remote warning unit of the early warning module sound an alarm when the data exceeds the threshold, display fault information and remotely notify. Multi-mode early warning ensures that staff are aware of abnormalities in a timely manner, and remote notification allows management personnel to grasp the situation at any time, facilitate rapid fault handling and reduce production losses.

[0050] Specifically, the early warning module is provided with a three-level early warning mechanism. The first-level early warning is a slight deviation early warning. When the data deviation value is between 10% and 20% of the standard threshold, only the display screen 12 will give a text prompt; the second-level early warning is a moderate deviation early warning. When the deviation value is between 20% and 30%, the display screen 12 will display a prompt and the sound and light alarm unit will emit an intermittent alarm sound; the third-level early warning is a serious deviation early warning. When the deviation value exceeds 30%, the display screen 12 will display a red alarm message, the sound and light alarm unit will emit a continuous alarm sound, and at the same time, the central processing module will control the relevant mechanisms to slow down through the drive control module;

[0051] The three-level early warning mechanism issues text prompts, intermittent alarms, continuous alarms and deceleration according to the degree of deviation through the display screen 12 and the sound and light alarm unit. Corresponding measures are taken for different deviations to avoid minor anomalies affecting production. In case of serious anomalies, equipment is controlled in time to reduce failure losses and improve operational safety.
