Description

Technical Field

[0001] The present invention relates to the technical field of polyethylene fiber spinnerets, and specifically to a microstructure regulation system and method for high-strength and high-modulus polyethylene fiber spinnerets. Background Art

[0002] A spinneret is the core component in chemical fiber production. It is in a plate shape with a dense arrangement of spinneret holes on it. The high-polymer melt or solution is extruded through the spinneret holes and forms fibers after cooling and solidification. The circular spinneret is the most commonly used type of spinneret at present.

[0003] The invention patent application with the application number 202010252776.8 discloses an automatic inspection method for the spinneret of a spinning component, including the following inspection steps: 1) obtaining multiple hole size values by measuring multiple holes of the spinneret through a microscope; 2) sending the hole size values to a processing unit through a set value sending module; 3) the processing unit receiving the hole size values and calculating the average value of the hole size values through a calculation module; 4) comparing the average value with a standard value through an error judgment module. If the average value exceeds the error range of the standard value, the processing unit sends out a result signal indicating that the spinneret is unqualified. If the average value does not exceed the error range of the standard value, the processing unit sends out a result signal indicating that the spinneret is qualified. This application aims to solve the problem that "the current inspection method for spinnerets mainly directly judges the quality of the spinneret holes by inspecting the sizes of the spinneret holes through a spinneret microscope. The main disadvantages of this inspection method are that each hole needs to be individually compared and inspected, resulting in low inspection efficiency and low inspection accuracy."

[0004] However, for the quality inspection of spinnerets, most of the existing technologies focus on the production process of spinnerets. During the use of spinnerets, due to mechanical vibration or other external factors, the spinneret may undergo small displacements, and these small displacements may accumulate and affect the accuracy of the fibers ejected from the spinneret. Therefore, a microstructure regulation system and method for high-strength and high-modulus polyethylene fiber spinnerets are proposed. Summary of the Invention

[0005] Aiming at the above-mentioned drawbacks of the existing technology, the present invention provides a microstructure regulation system and method for high-strength and high-modulus polyethylene fiber spinnerets, which can effectively solve the problems of the existing technology.

[0006] To achieve the above purposes, the present invention is realized through the following technical solutions: The present invention discloses a microstructure regulation system for high-strength and high-modulus polyethylene fiber spinnerets, including: A camera module for collecting morphological images of fiber filaments ejected during the operation of a spinneret plate and storing the morphological images of the fiber filaments; a detection module for obtaining the morphological images of the fiber filaments in the camera module, analyzing the similarity and symmetry of the morphological images of each fiber filament, and comprehensively estimating the accuracy of the fiber filaments ejected by the spinneret plate based on the analysis results of the similarity and symmetry; a determination module for setting a qualified determination threshold, receiving the estimation result of the accuracy of the fiber filaments ejected by the spinneret plate in the detection module, and comparing the estimation result with the qualified determination threshold to determine whether the fiber filaments ejected by the spinneret plate are qualified; a monitoring module for receiving and recording the estimation result of the accuracy of the fiber filaments ejected by the spinneret plate in the detection module and monitoring whether there is a regulation tendency of the spinneret plate based on the recorded estimation result; a regulation module for regulating the spatial attitude structure of the spinneret plate; a regulation message generation module for generating a spinneret plate regulation message Further, the camera module is integrated by four high-definition industrial cameras. The four high-definition industrial cameras are equidistantly arranged around the fiber filaments ejected during the operation of the spinneret plate, and the image acquisition perspectives of the four high-definition industrial cameras are all perpendicular to the fiber spinning direction of the spinneret plate; A sensing unit is arranged inside the camera module. The sensing unit is integrated by an audio sensor, and the sensing unit is used to sense the audio spectrum of the operating environment of the spinneret plate; Among them, in the initial operation stage, the camera module operates based on the operation frequency preset by the user at the system end, and coordinates the operation frequency in real time by applying the change of the ambient audio spectrum sensed by the operation of the sensing unit.

[0007] Further, the linear distance between the sensing end of the sensing unit and the spinneret plate is not greater than 0.5 m and there is no obstacle between them, and the sensing end of the sensing unit faces any surface of the spinneret plate; The sensing unit operates continuously based on a fixed frequency, and the fixed frequency used for the operation of the sensing unit is higher than the operation frequency preset by the user at the system end in the initial operation stage. The logical representation of the operation frequency of the camera module coordinated in real time by applying the change of the ambient audio spectrum sensed by the operation of the sensing unit is: ; In the formula: is the difference between the spectrum matrices x and y obtained by short-time Fourier transform of two audio spectra; are the frequency dimension and frame index; is the sensing weighting function; is the mean square error distance; is the cosine distance; Among them, The larger it is, the higher the operation frequency of the camera module. On the contrary, the operation frequency of the camera module approaches the operation frequency preset by the user at the system end, , is a key feature in the spectrum of the nth frame, and the key feature is any one of frequency domain energy, formant position, and Mel Frequency Cepstral Coefficient (MFCC).

[0008] Furthermore, the mean squared error distance and the cosine distance are calculated as follows: ; In the formula; is the total number of frequency bins; , are the amplitude values of two audio signals at the nth frame and the mth frequency bin respectively; where, and When calculating, the mean squared error distance and cosine distance are calculated separately for each frame in the spectrum matrix, and then summed up in the time dimension as the mean squared error distance and cosine distance for final application.

[0009] Furthermore, when the camera module stores the fiber filament morphology images, it distinguishes and stores them based on the source high-definition industrial camera of the fiber filament morphology images, and the fiber filament morphology images stored in each distinguished storage interval are sorted and stored based on the acquisition time sequence; Before the detection module analyzes the similarity and symmetry of each fiber filament morphology image, in the stage of obtaining the fiber filament morphology images, the target is to obtain the fiber filament morphology images stored most recently in each distinguished storage interval in the camera module; When the monitoring module monitors that the estimated results continuously judged as qualified by the judgment module show a continuous downward trend for three consecutive times, it indicates that there is a regulation tendency for the spinneret, otherwise, it indicates that there is no regulation tendency for the spinneret; Among them, when the judgment result of the judgment module is no or the monitoring result of the monitoring module is yes, the regulation module is triggered to run. In the stage when the regulation module is triggered to run, the equipment to which the spinneret belongs stops running, and the equipment to which the spinneret belongs resumes running until the regulation module ends running.

[0010] Furthermore, the estimation logic for the accuracy of the fiber filaments spun by the spinneret in the detection module is as follows: Capture the pixels that match the fiber filament color value in the fiber filament morphology image according to the fiber filament color value, form a fiber filament contour image with all the captured pixels, and analyze the similarity and symmetry of each fiber filament morphology image by applying the fiber filament contour image; Configure weights for the similarity analysis result and symmetry analysis result, multiply the similarity analysis result and symmetry analysis result by their respective corresponding weights and then sum them up, and the sum result is recorded as the accuracy of the fiber filaments spun by the spinneret; Among them, the larger the number of spinneret holes on the spinneret plate, the greater the weight value assigned to the similarity analysis result and the smaller the weight value assigned to the symmetry analysis result. Conversely, the smaller the number of spinneret holes on the spinneret plate, the smaller the weight value assigned to the similarity analysis result and the greater the weight value assigned to the symmetry analysis result. Both weights are non-zero positive numbers, and the sum of the two weights is equal to one.

[0011] Furthermore, the control module is integrated by no less than two gyroscopes and a universal adjustment component. The standard attitude parameters of the spinneret plate are pre-stored in the gyroscopes, and the initial attitude parameters of the spinneret plate and the attitude adjustment movement path are stored in the universal adjustment component. During the operation of the control module, the spinneret plate is driven back to its initial attitude through the universal adjustment component based on the initial attitude parameters of the spinneret plate. After the spinneret plate returns to its initial attitude, it is driven to move based on the attitude adjustment movement path. During the movement of the spinneret plate, the attitude parameters of the spinneret plate are continuously sensed by the gyroscopes. When the sensed real-time attitude parameters of the spinneret plate are consistent with the standard attitude parameters stored in the gyroscopes, the operation of the universal adjustment component is controlled to end, and the current attitude is maintained, indicating the end of the control of the spatial attitude structure of the spinneret plate by the control module. Among them, the attitude parameters include pitch angle, yaw angle, and roll angle, and the attitude adjustment movement path of the spinneret plate consists of several sets of attitude parameters.

[0012] Furthermore, the content of the spinneret plate control message generated by the control message generation module includes: the single control duration of the spinneret plate and the average interval time of continuous control of the spinneret plate.

[0013] Furthermore, the camera module is internally connected to the sensing unit through a wireless network, the camera module is connected to the monitoring module through a wireless network, the detection module is connected to the determination module and the monitoring module through a wireless network, the determination module and the monitoring module are connected to the control module through a wireless network, and the control module is connected to the control message generation module through a wireless network.

[0014] On the other hand, a method for regulating the microstructure of a high-strength and high-modulus polyethylene fiber spinneret plate includes: Collect the morphological images of the fiber filaments ejected from the spinneret plate through a high-definition industrial camera, and store the morphological images; obtain the stored morphological images of the fiber filaments, analyze the similarity and symmetry of the morphological images of the fiber filaments, and estimate the accuracy of the fiber filaments ejected from the spinneret plate in combination with the analysis results of the similarity and symmetry of the morphological images of the fiber filaments; set a qualified judgment threshold, obtain the estimation result of the fiber filament accuracy, compare the estimation result with the qualified judgment threshold, and judge whether the fiber filaments are qualified; continuously record the estimation results of the accuracy of the fiber filaments ejected from the spinneret plate, and monitor in real time whether there is a tendency to adjust the spinneret plate based on the recorded estimation results; when the judgment result is no or the monitoring result is yes, adjust the spatial attitude structure of the spinneret plate; generate the real-time control message of the spinneret plate.

[0015] Adopting the technical solution provided by the present invention, compared with the known prior art, it has the following beneficial effects: The present invention provides a micro-structure control system and method for a high-strength and high-modulus polyethylene fiber spinneret plate. During the execution of the system and method, multiple high-definition cameras are used to collect the morphological images of the fiber filaments around the spinning direction, and the acquisition frequency is dynamically adjusted in combination with the change of the environmental audio spectrum, so as to accurately capture the subtle features of spinning abnormalities; based on the analysis of the similarity and symmetry of the fiber filament contour images, the weights are intelligently configured according to the number of spinneret holes to improve the calculation accuracy and realize the accurate evaluation of the spinning state; when detecting a control tendency such as a continuous decrease in qualified results, the spinneret plate is driven by a gyroscope and a universal adjustment component to adjust its attitude according to a preset path, so that the attitude parameters of the spinneret plate return to the standard values, and the control message generates data such as the control duration, providing a quantitative basis for process optimization, thereby realizing the full-process control and maintenance from dynamic monitoring, intelligent evaluation to accurate control.

And both weights are non-zero positive numbers, and the sum of the two weights is equal to one; The determination module is used to set a qualified determination threshold, receive the accuracy estimation result of the fiber filaments ejected by the spinneret in the detection module, and compare the estimation result with the qualified determination threshold to determine whether the fiber filaments ejected by the spinneret are qualified; The monitoring module is used to receive and record the accuracy estimation result of the fiber filaments ejected by the spinneret in the detection module, and monitor whether there is a regulation tendency of the spinneret based on the recorded estimation result; When the camera module stores the fiber filament morphology images, it differentiates and stores them based on the source high-definition industrial camera of the fiber filament morphology images, and the fiber filament morphology images stored in each differentiated storage interval are sorted and stored based on the acquisition time sequence; Before the detection module analyzes the similarity and symmetry of each fiber filament morphology image, in the stage of obtaining the fiber filament morphology images, the target is to obtain the fiber filament morphology images stored most recently in each differentiated storage interval in the camera module; When the monitoring module monitors that the estimated results continuously judged as qualified by the judgment module for three consecutive times show a continuous downward trend, it indicates that there is a tendency to regulate the spinneret, otherwise, it indicates that there is no tendency to regulate the spinneret; Among them, when the operation judgment result of the judgment module is no or the monitoring result of the monitoring module is yes, the regulation module is triggered to operate.
