Due to poor fluidity and easy agglomeration of chemical ultra-fine powders (such as nano-silicon powder, titanium dioxide), the measurement error of traditional ton bag packaging equipment often exceeds ±1.5%, bringing huge cost losses to enterprises. A fine chemical enterprise once had 500 bags of products returned by customers because the actual weight of each 1-ton powder bag deviated by 15kg, resulting in a direct loss of over 2 million yuan; another enterprise had a raw material loss rate of 3% due to inaccurate measurement, wasting over 1 million yuan annually. The Automatic Ton Bag Powder Packaging Machine stabilizes the measurement precision at ±0.1% through dual-sensor collaborative control technology, completely solving the deviation pain point.
The core of the equipment's precision control comes from three technical guarantees. Firstly, the dual-sensor weighing system: the main sensor has a precision of 0.01g, and the auxiliary sensor performs real-time calibration to dynamically capture changes in material weight. After feedback to the PLC system, it automatically switches between "coarse feeding + fine feeding" modes. Coarse feeding quickly conveys 90% of the material, and fine feeding performs fine-tuning at the 0.1g level to eliminate overweight caused by "impact feeding". Secondly, anti-adhesion residue design: all parts in contact with materials are coated with Teflon, combined with a 60Hz high-frequency vibration feeding device to completely remove wall residues and ensure accurate feeding volume each time. Thirdly, intelligent reweighing verification: after each bag is packaged, it automatically enters the reweighing link. If the error exceeds ±0.1%, it immediately triggers the feeding or discharging program to ensure 100% qualification of delivered products.
