Film material tension compensation method based on detection of thickness uniformity of dishwashing bead water-soluble film

PendingCN122364830APrecise separationaccurate responseMembrane tensionFeature vector
This invention relates to a membrane tension compensation method based on the detection of uniformity in the thickness of water-soluble membranes produced by dishwashing pods. Addressing the problem that membrane thickness distribution is sensitive to nonlinear tension disturbances under high-speed operation conditions during water-soluble membrane production, and that traditional thickness control methods struggle to achieve precise closed-loop compensation, this invention proposes a method that continuously collects cross-sectional thickness information of the membrane material, constructs a time-space thickness sequence, extracts thickness gradient topological features, combines a multidimensional tension sensitivity feature vector with a dynamic thickness gradient topological graph, and uses a layer-by-layer sparsely connected lightweight graph convolutional network to infer the tension compensation amount. After median filtering and denoising, the result drives the actuator to adjust in real time, achieving high-precision closed-loop compensation for the uniformity of the water-soluble membrane thickness. This method improves the sensitivity and stability of thickness control under nonlinear disturbance environments, while also possessing both real-time performance and computational efficiency.
