Structural Characteristics and Technical Requirements of Electronic Screw Weighing Feeder

The electronic screw weighing feeder is an automated feeding device that integrates metering, conveying, and control functions. Its main advantages include precise metering, good stability, and simple operation, making it widely applied in industries such as chemicals, food, pharmaceuticals, and light industry. It plays a crucial role in production batching operations, production management and control, and information-based production management.

Structural Characteristics of Electronic Screw Weighing Feeder:

1. Electronic Dynamic Weighing and Automation: It combines electronic dynamic weighing, automated PLC (Programmable Logic Controller), and screw drive mechanisms to achieve continuous metering and control of materials.

2. High-Precision Weighing Sensors and Intelligent Control Instruments: The use of high-precision weighing sensors and intelligent weighing control instruments allows for adaptive error correction, ensuring accurate and stable weighing.

3. Controlled Inlet and Outlet: The inlet, outlet, and conveying pipelines are equipped with pneumatic or electric valves to control the supply and cessation of materials, ensuring stable control accuracy.

4. Compact Structure and Easy Maintenance: The feeder features a compact structure, is easy to operate, and requires minimal maintenance.

5. Sealed Screw Conveyor Design: The screw conveyor is sealed to prevent material leakage and maintain a clean working environment.

6. Flexible Cleaning Configuration: It can be flexibly configured with cleaners to automatically remove adhered materials, preventing repeated weighing.

7. Bearing Mounts on Shell Exterior: Mounting bearings on the exterior of the shell facilitates easy inspection and maintenance.

Technical Requirements for Electronic Screw Weighing Feeder:

1. Metering Accuracy: The metering accuracy should comply with relevant national standards, remaining below 10‰ and maintaining stability.

2. High-Precision and Reliable Components: Weighing sensors and metering control instruments must possess high precision, high reliability, and good stability.

3. Conveying Flow Range and Speed: The conveying flow range and speed should be designed and selected according to production process requirements.

4. Automated Control Functionality: It should have automated control capabilities, enabling data interaction and collaborative operation with other equipment on the production line.

5. Stable Material Flow: The feeder should ensure a uniform and stable material flow, preventing material surges and blockages.

6. Durability and Corrosion Resistance: The feeder should be wear-resistant, corrosion-resistant, and rust-proof to meet industrial environment application requirements.

7. Advanced Instrument Features: The feeder's instrument should have PID (Proportional-Integral-Derivative) regulation and various compensation functions, including automatic calibration, automatic interval adjustment, automatic fault diagnosis, and automatic zero-point tracking to enhance and maintain accuracy.

8. Safety Protection Measures: Adequate safety protection measures should be in place to prevent mechanical failures and personal injuries.

In practical use, the electronic screw weighing feeder offers high production efficiency and economic benefits, finding wide application across various industries. In summary, the electronic screw weighing feeder is not only accurate, stable, and safe but also easy to operate, simple to maintain, and has a long service life, enhancing work efficiency and production quality while creating greater value for enterprises.
