This application relates to a feeding device for a polystyrene foam molding machine, belonging to the technical field of plastic processing. It includes a storage cylinder positioned above the foam molding machine body, a collecting hopper below the storage cylinder, a distributing cone installed inside the collecting hopper, and multiple guide pipes fixedly connected around the distributing cone. The openings of the guide pipes are equidistantly arranged around the axis of the distributing cone. The ends of the guide pipes away from the collecting hopper are positioned above the foam molding machine body and spaced apart along the length of the foam molding machine body. Multiple distributing plates are positioned above the foam molding machine body, arranged along the length of the foam molding machine body, and each distributing plate corresponds to and is fixedly connected to one of the guide pipes. A driving assembly is provided on the foam molding machine body to move the distributing plates on the foam molding machine body. This application has the effect of improving the uniformity of raw material distribution within the foam molding machine.

The application relates to the technical field of textile printing and dyeing, and discloses a waterless printing and dyeing process intelligent control method and system.The method comprises the following steps: collecting dye dispersion and fabric fiber density data in a waterless medium, and generating an initial concentration distribution map; inputting a convolutional neural network to identify concentration instability regions and local deviation values; if the deviation exceeds a preset threshold, iteratively optimizing dye injection parameters to obtain an optimized concentration distribution map; segmenting the regions and extracting dye penetration path vectors of high fiber density regions; determining regional adsorption adjustment coefficients through a support vector machine; updating the parameters to obtain a dynamic concentration regulation sequence; iteratively optimizing the final uniform coloring distribution through coloring simulation; and extracting quality indicators to optimize process parameters and determine a production compatibility scheme.The application solves the problem of uneven dye dispersion through multi-dimensional data fusion and intelligent algorithm regulation, and improves coloring uniformity, process stability and production compatibility.
