Standard Integrated Weighing and Packaging Machine

Overcoming Inaccuracy in High-Speed Packaging

Processing granular and powder products often faces the challenge of weight inconsistency and product spillage at high speeds. Conventional systems fail to maintain ±0.3g per bag when running near full capacity, resulting in material loss and production delays.
The SIWP-1500 is engineered to solve this by utilizing multi-head precision weighing and fully automated PLC monitoring. This ensures accurate fills, minimal waste, and reliable operation in continuous industrial environments.

Engineering Logic & Technical Advantages

• Feature 1: Multi-Head Weighing System

  • The Engineering: Equipped with 10 independent load cells, each with a 0.1g resolution.

  • The Impact: Enables rapid selection and combination to achieve ±0.3g accuracy, reducing overfill by up to 4% per production batch.

• Feature 2: Stainless Steel Construction

  • The Engineering: Constructed entirely from SUS304 stainless steel, 3.5mm thick with precision welding (tolerance ±0.2mm).

  • The Impact: Complies with HACCP and FDA standards while resisting abrasive and acidic powders.

• Feature 3: PLC-Controlled Automation

  • The Engineering: Integrated Siemens S7-1500 PLC with real-time monitoring of weighing speed, vibration amplitude, and fill timing.

  • The Impact: Reduces manual intervention by 50%, maintains precise weight control, and enables automatic recipe switching for multiple products.

• Feature 4: High-Speed Bagging Integration

  • The Engineering: Servo-driven vertical bagging unit with 0.2s bag forming cycle.

  • The Impact: Maximizes throughput up to 1500kg/hr, minimizing downtime and labor costs.

• Feature 5: Anti-Caking & Flow Management

  • The Engineering: Vibratory feeders with adjustable amplitude (0–6mm) and inclined screw augers.

  • The Impact: Maintains continuous flow for sticky or hygroscopic powders, avoiding blockage and unplanned halts.

Production Workflow & Integration

The SIWP-1500 integrates seamlessly into high-speed packaging lines:

1. Intake: Receives product from upstream bulk hopper or pneumatic conveyor.

2. Processing: Multi-head weigher dispenses material precisely while monitoring load cells and vibration patterns.

3. Discharge: Automatically forms and seals bags, delivering finished product to downstream conveyors or robotic palletizers, reducing labor dependency.
