Publication number: 20200282596Abstract: An interlayer mixing apparatus for texturing man-made stone slabs has a pressing assembly, a coloring component, a stirring assembly, a moving assembly, and a control system. A conveyor belt sequentially conveys a slab to working areas of the pressing assembly, the coloring component, and the stirring assembly which are separately connected to the control system. The pressing assembly presses the slab before the pigment and the slab are stirred, so that the texture boundary on the final product is clearer and more complete. The control system moves the moving assembly to position the stirring assembly according to a texture route, while the stirring assembly performs stirring on a part of the surface of the slab, to stir a pigment layer with a raw material layer on the slab.Type: ApplicationFiled: April 27, 2020Publication date: September 10, 2020Inventors: Jianping Qiu, Shiyang Zhu, Yexin Pan
