PVC (polyvinyl chloride) low-foaming board mixing device

Abstract

According to the PVC low-foaming board mixing device provided by the utility model, the feeding hopper, the spiral conveying assembly, the hot mixing machine, the cold mixing machine and the storage bin are arranged, so that the full-process automatic operation of raw materials from automatic feeding, quantitative conveying, staged mixing to final collection is realized, the production efficiency is improved, and the manual intervention is reduced; the spiral conveying assembly is of a double-feeding-screw structure, and feeding is more uniform and efficient; the hot mixing machine and the cold mixing machine are separately arranged, so that the heating premixing and cooling uniform mixing processes of raw materials are effectively realized, the influence of overheating on physical properties is avoided, and the mixing quality is improved; a regeneration hopper is arranged at the top of the cold mixing machine, and regenerated materials are introduced in the cold mixing stage, so that the recycling efficiency is improved, and the performance consistency of finished products is guaranteed; vibration assemblies are arranged on the outer sides of the feeding pipeline, the hot mixing machine shell, the cold mixing machine shell and the storage bin, raw materials can be effectively prevented from being blocked, hung on the wall or bridged, and it is guaranteed that the materials flow smoothly.
