Automatic Quantitative Packaging Machine

The FDCS series automatic quantitative packaging machine can meet the automatic quantitative packaging requirements of ton bags for various powder and granular materials. It features high weighing accuracy, high filling speed, less dust leakage, stable and reliable performance, and convenient operation and maintenance. It is an ideal packaging equipment integrating weighing and bagging for bulk materials. Different feeders are selected according to different material characteristics. The appropriate feeder type is the key to the normal operation of the packaging machine. When placing an order, the material sample and packaging bag must be provided, and the special characteristics of the material during the actual packaging process must be described in as much detail as possible.

Structural Composition (Core Components)

- Bin body: Made of Q235B or stainless steel, cylindrical/square structure, smooth inner wall anti-sticking, volume designed according to production capacity (commonly 1~50m³).

- Weighing system: Including weighing sensors (cantilever beam type/bridge type) and weighing instruments, core for weight signal acquisition and display.

- Feeding device: Equipped with pneumatic butterfly valve/gate valve to control material entry, avoiding metering errors caused by too fast feeding.

- Discharging device: Equipped with screw conveyor and pneumatic discharge valve at the bottom, supporting uniform discharging and adapting to subsequent batching processes.

- Arch-breaking device: Pneumatic arch breaker or vibration motor, solving cement caking and bridging issues, ensuring smooth discharging.

- Control system: Interlocked with the main production line PLC, supporting manual/automatic switching, real-time display of weight, accumulated quantity, batching times and other data.

- Safety devices: Equipped with breather valve and dust filter at the top (preventing dust leakage), and inspection port and level indicator on the bin body (monitoring material level).

Core Features

1. Control System

- FCS+DCS dual-system architecture: Combining fieldbus technology with distributed control, control accuracy up to ±0.1%, far exceeding the ±0.5% of traditional DCS systems.

- Full digital communication: Strong anti-interference capability, stable signal transmission, enabling remote monitoring and parameter adjustment.

- PLC + weighing instrument dual-core control: Ensuring high-speed sampling (200 times/second A/D conversion) and precise control.

2. Performance

- Packaging speed: Depending on the model, up to 150-180 bags/hour (FDCS-5003) to 1200 bags/hour.

- Metering accuracy: Static error ≤±20g, dynamic error ≤±3kg, bag weight pass rate ≥98%.

- Packaging range: 5kg-50kg, can be customized to larger specifications according to requirements.

3. Intelligent Functional Design

- Multi-stage feeding system: Adopting fast, medium and slow three-speed feeding, balancing speed and accuracy.

- Automatic error correction: Automatic compensation for material drop, automatic zero tracking.

- Recipe storage: Can store 10-20 packaging weight parameters, one-click switching for different products.

- Fault self-diagnosis: Real-time monitoring, automatic alarm and display of fault location.

4. Structural and Material Advantages

- Fully enclosed dust-proof design: Equipped with dust collection system, dust emission ≤0.01g/m³, meeting environmental protection requirements.

- Modular design: Easy assembly and disassembly, convenient maintenance, quick replacement of wearing parts.

- Food-grade material: Parts in contact with material use 304 stainless steel, corrosion-resistant, meeting hygiene standards.

Working Principle

1. Manual/automatic bag feeding → Bag clamping mechanism automatically senses and clamps

2. Material conveying → Screw feeder/vibration feeder delivers material to weighing hopper

3. Weighing:

- Fast feeding (50Hz): Quickly approaches target weight

- Medium feeding (25Hz): Precisely approaches

- Slow feeding (15Hz): Micro-compensation to ensure accuracy

4. Weight reached → Discharge door opens, material falls into packaging bag

5. Automatic sealing/bag sewing → Conveyed to next process

6. System resets to zero → Enters next cycle
