Main Material Weighing Bin

The China Main material weighing bin manufactured by FANCHANG Machinery Factory has the core function of achieving high-precision and continuous quantitative conveying of the main raw materials in PVC production. The specific functions are as follows:

1. Precise measurement and batching: Real-time and continuous weight monitoring of PVC resin powder, and accurately transporting the materials to the hot mixing machine at the preset rate according to the formula;

2. Continuous feeding: Based on the "weight loss method" principle, it ensures that while the weighing bin supplies materials to the production line, the system can continue to operate, achieving uninterrupted production;

3. Automatic feeding control: When the material weight in the bin is lower than the set lower limit value, the system automatically starts the feeding device (such as pneumatic conveying, screw feeding machine, etc.) for rapid replenishment; during the replenishment period, the system automatically switches to the "volumetric" compensation mode to ensure stable output flow;

4. Process integration and control: As part of an automated production line, it interacts with the upstream storage bins and the downstream hot mixing machine, accepting instructions from the central control system to achieve full-process automation;

5. Data monitoring and feedback: Real-time monitoring and feedback of key data such as material weight, instantaneous flow rate, cumulative weight, and equipment status, providing a basis for production management and quality traceability.

Product features

Our Main material weighing bin directly performs static weighing of the materials (measuring the weight loss of the entire silo), which is more accurate compared to traditional dynamic weighing; it has strong anti-interference capabilities and measures the total weight of the silo, being less affected by factors such as material properties (such as fluidity, density changes) and mechanical vibrations; it is modular and customizable, allowing the design of silos of different volumes and structures (square, circular) based on the production line capacity and factory space; for PVC powder characteristics (easy bridging, medium fluidity), it is equipped with a dedicated anti-bridging device and discharge device; it has a fully sealed structure, ensuring complete sealing from feeding, weighing to discharging, effectively preventing PVC dust from escaping, meeting environmental protection and occupational health and safety requirements; it reduces material moisture and contamination, ensuring raw material cleanliness; it is intelligent controlled, integrating high-precision weighing sensors and intelligent instruments, using PLC or dedicated controllers, with advanced control algorithms built-in, capable of quickly responding to flow deviations and ensuring stable output; it is equipped with a human-machine interface (HMI), facilitating parameter setting, operation monitoring and fault diagnosis.
