Facing the high-standard requirements of color-coated aluminum plate printing, this device performs poorly in coating thickness control, making it difficult to accurately correct the coating at multiple stages when the coating roller is running at high speed. This easily leads to defective products with excessive thickness. Furthermore, during long-term continuous feeding, if particles settle to the bottom causing sudden changes in local concentration or slight blockage of the pipeline, it greatly interferes with the uniform distribution of the coating on the coating roller surface, resulting in inconsistent output concentrations and uneven coating thickness, leading to problems such as printing color differences and defective products.
