Product Overview
PVC additives auto weighing system is a high-precision intelligent automatic batching equipment specially developed for PVC extrusion production lines. It replaces traditional manual weighing operations to achieve full-automatic quantitative weighing, batching and feeding of various powder and granular additives such as stearic acid, wax, titanium dioxide and carbon black. The whole machine adopts 304 stainless steel for material contact parts to avoid contamination. Equipped with imported Mettler Toledo weighing sensor and Siemens intelligent control system, the equipment features high precision, stable operation and large production capacity. It supports simultaneous weighing of multiple ingredients, stores up to 30 production formulas, and provides dual automatic/manual operation modes. The system effectively solves the problems of low manual batching efficiency, large error, easy pollution and unstable product quality, realizes dust-free, standardized and intelligent batching production, and is the core supporting equipment for modern PVC plastic production.
Application and introduction
The PVC additives auto weighing system is professionally developed to replace traditional inefficient and error-prone manual weighing processes. It is specially designed for PVC extrusion production lines to realize fully automatic quantitative weighing and batching of various common powder and granular additives, including stearic acid, wax, titanium dioxide, whitener, carbon black and other auxiliary materials. The system can accurately weigh the required dosage of each additive for a single production batch independently, effectively eliminating weighing errors, formula deviation and unstable product quality caused by manual operation. Adopting fully enclosed automatic feeding and metering structure, it completely avoids material leakage and dust flying, maintaining a tidy, dust-free and standardized workshop environment. This intelligent batching equipment supports simultaneous automatic weighing of 5 to 12 kinds of additives with high comprehensive precision, making it an ideal supporting system for high-standard PVC extrusion production.
