Description: It is the core component for weight detection in fully automatic quantitative packaging machines. It belongs to high-precision force-sensing elements and directly determines the packaging weighing accuracy.
1. Weight Signal Collection: Real-time detection of the material weight in silos and bags, converting physical gravity into standard millivolt-level electrical signals, and transmitting them to the packaging machine's weighing instrument.
2. Quantitative Closed-Loop Control: Works with the control system to achieve staged feeding: fast feeding → slow feeding → precise feeding → stop machine and clamp bag, accurately locking the target net weight (e.g., 25kg, 50kg finished product bags) to prevent overweight or underweight packages.
3. Dynamic Weighing Compensation: Adapts to the impact of material discharge in packaging machines, material drop height, and bag weight shaking, with real-time filtering and anti-vibration to ensure stable weighing during continuous packing.
4. Overload Safety Protection: Equipped with an overload limit structure to prevent damage to the internal strain core caused by full bag impact or accidental heavy pressure.
The overall structure is a single-point cantilever beam. With a single-point bearing structure, a single sensor can complete the weighing of the entire hopper, without the need for multi-point parallel connections.
Internal Strain Elements: High-precision metal foil strain gauges.
