Product Overview
Rubber and PVC additives auto weighing system is a high-precision intelligent auxiliary batching equipment developed for PVC, rubber and plastic extrusion industries. Aiming at the problems of low efficiency, large error, easy dust pollution and unstable manual batching quality in traditional production, the equipment realizes full-automatic precise weighing and batching of various powder and granular additives such as stearic acid, wax, titanium dioxide and carbon black. The system adopts screw quantitative feeding mode, matched with imported Mettler Toledo high-precision weighing sensors and Siemens intelligent control system, with the highest control accuracy up to ±5g. It supports simultaneous weighing of 3-12 kinds of additives, with stable and efficient feeding speed. The whole machine adopts 304 stainless steel silos and international brand electrical accessories, featuring reliable performance, simple installation and convenient operation. It can effectively avoid manual weighing errors, stabilize product quality, improve workshop cleanliness, and is an essential supporting equipment for standardized and high-precision production of PVC and rubber products.
Application and introduction
The rubber and PVC additives auto weighing system is a professional intelligent batching equipment independently developed to replace traditional inefficient manual weighing operations. It is specially designed for PVC and rubber extrusion production lines, focusing on automatic and precise weighing of various small-dose auxiliary materials commonly used in plastic and rubber processing. The system is applicable for a wide range of additives including stearic acid, wax, titanium dioxide, whitener, carbon black and other powdery and granular ingredients. It can automatically complete quantitative weighing according to single-batch production formula requirements, thoroughly avoiding weighing errors, formula deviation and product quality instability caused by manual operation. Meanwhile, the fully closed automatic feeding and weighing structure effectively prevents material dust leakage, maintaining a clean, dust-free and standardized production workshop environment. The system supports automatic weighing of 5 to 12 kinds of powder or granular additives at one time, with extremely high weighing precision, and the overall weighing accuracy is controlled within 10g, meeting the high-precision batching requirements of high-end PVC and rubber products.
