Engineered for continuous, high-volume extrusion facilities, this computer-controlled automatic feeding dosing mixing conveying system fundamentally transforms raw material handling. Designed specifically for large-scale PVC processing enterprises manufacturing SPC flooring, PVC pipes, and plastic window profiles, the equipment smoothly adapts to accommodate LVT, WPC, and even specialized rubber production lines. By addressing the severe limitations of the traditional manual mixing process—which remains viable only for low-output, small factories—this system establishes a fully automatic unmanned material processing loop. From the initial raw material feeding and classified storage to proportional dosing, homogeneous mixing, and final finished compound feeding to the extruder, every phase operates with mechanical precision.
The whole set equipment adopts a vacuum closed pneumatic conveying structure to entirely avoid powder dust leakage, maintaining a pristine workshop environment. It supports the synchronous feeding and dosing of virgin PVC raw material, heavy CaCO3 filler, and plastic recycled material. Engineered with seven independent matched functional units, it forms a complete closed-loop production line capable of sustaining a high-throughput processing capacity ranging from 500kg/h up to 2500kg/h. The whole feeding and batching process is strictly controlled by a central computer program, ensuring stable weighing precision and a highly adjustable material formula.
It completely eliminates manual participation in the whole production process, drastically improves workshop production efficiency, and strictly complies with international environmental dust-free production standards. Demonstrating its industrial reliability, this system has been officially put into operation in Eletile Co., Ltd SuZhou factory in 2020, specially used for supporting the full-process automatic feeding, dosing, mixing, and conveying work of their active SPC floor extrusion production line.
The traditional manual mixing and handling mode is only suitable for small plastic factories, plagued by three inherent operational defects that hinder enterprise scaling:
Artificial mixing is extremely easy to make a mistake. Because this is a physically demanding repetition work, the worker is tired easily. As concentration drops throughout a shift, the weighing precision is not assured, directly compromising the structural integrity and visual consistency of the final extruded profiles.
Labour intensity is exceptionally large, requiring a massive headcount to transport and load heavy bulk materials. Consequently, the human cost is unsustainably high from a long term view, severely diminishing overall plant profitability and operational flexibility.
Direct physical contact with volatile chemical raw material and fine airborne powders continually harms the worker’s health. Without a closed-loop system, factories struggle to maintain clean air standards, increasing the risk of compliance violations and respiratory hazards.
The complete PVC automatic mixing conveying system consists of seven highly integrated core parts, each engineered for specific material handling tasks:
Firstly, solve all manual production defects fundamentally. It completely avoids manual weighing error, slashes long-term labor cost expenditure, and prevents the physical damage caused by chemical raw material contact.
Secondly, computer full automatic control. Driven by an advanced PLC system with digital storage for complex formulas, it realizes true unmanned feeding, weighing, dosing, mixing and extruder feeding, reducing on-site worker quantity greatly.
Thirdly, full dust-free closed conveying. Adopt vacuum pneumatic sealed pipeline and silo conveying, ensuring absolutely no dust floating, easily meeting strict workshop environmental protection requirements and occupational health standards.
Fourthly, high and stable dosing precision. Computer fixed material ratio replaces subjective manual operation, utilizing precise load cells to guarantee consistent finished SPC floor and PVC product quality cycle after cycle.
Fifthly, multi-material compatible capability. Support the synchronous processing of PVC new material, dense calcium carbonate filler and irregular recycled plastic material, perfectly meeting factory waste recycling production demands without clogging.
Sixthly, integrated modular design. The seven functional units match perfectly, making the entire plant highly convenient for rapid installation, streamlined debugging and straightforward daily maintenance.
Seventhly, wide industry applicability. Beyond its primary function, it is fully compatible with SPC floor, LVT/WPC flooring, PVC water pipe, plastic window profile and other full-series PVC or rubber product production lines.
Eighthly, mature field application effect. Successfully put into production in 2020 SuZhou factory, demonstrating long-term stable operation, highly suitable for large-volume continuous extrusion production environments.
