Problems solved by technology

[0004] Existing artificial quartz stone companies prepare artificial quartz stone water pattern plates through multiple roller rolling. Due to more manual intervention, the prepared water pattern plates have poor naturalness and uneven water pattern uniformity on the entire plate surface, which is difficult to produce. Achieve batch stability and consistency, low output, resulting in less supply of artificial quartz stone water pattern plates and high prices
At present, there is no process to prepare artificial quartz stone water pattern plate by extrusion molding at home and abroad.

Abstract

The invention discloses a screw extrusion machine, and belongs to the field of man-made stone plates. The machine comprises a cylinder, the cylinder is outside provided with a motor and is inside provided with a screw conveying shaft, one end of the screw conveying shaft stretches out of the cylinder and is connected with the motor via a shaft coupling, the upper side of the cylinder is provided with a material inlet, and the right end of the cylinder is provided with an extrusion discharge port. The invention also discloses a preparation method for a man-made quartz-stone corrugated plate. The method comprises the following steps: preparing ingredients, mixing the ingredients, extruding, distributing the ingredients, compacting, solidifying, setting a thickness, and polishing. By employing extrusion molding for preparing the man-made quartz-stone corrugated plate, the prepared man-made quartz-stone corrugated plate possesses natural, smooth and well-uniform plate surface textures, the water-wave texture is relatively fine and smooth compared with the water-wave texture formed through roller rolling, and the prepared corrugated plate possesses batch stability consistency. Also, production efficiency is improved, manpower cost is saved, and the preparation method is applicable to large-scale industrialized production.

Description
