Motor Applications in Multifunctional Packaging Machines

1. Component Overview

The multifunctional packaging machine is a critical piece of equipment in the food processing industry, widely used for automating the packaging of food items like granules, powders, and liquids. This equipment integrates various functions such as conveying, metering, sealing, and cutting into one unit, and is composed of the following parts:

• Conveying System: Uses multiple conveyor belts and rollers driven by synchronized servo motors to ensure accurate product transport.
• Metering Device: Employs load cells and stepper motors to precisely control the material weight in each package, ensuring consistent product weight.
• Forming Device: Uses forming rollers and guide devices in combination with motors to precisely adjust and shape the packaging film.
• Sealing and Cutting System: Electric heating wires and cutting tools, driven by stepper or servo motors, perform sealing and cutting actions.
• Control System: The PLC controller works with a motion controller to integrate operation commands for multi-axis motors, ensuring accurate synchronization of movements.

2. Working Principle

When the machine operates, products are transported by the conveying system into the metering device. After the material is weighed by the electronic scale, the metering motor controls the distribution of material according to preset parameters. The packaging material is formed into a tube shape and delivered to the filling area. Then, the sealing system uses heat sealing and cooling to form a sealed package, and the cutting mechanism precisely divides it into individual packages. Throughout the process, multiple motors work together to synchronize the material flow, packaging material, and mechanical movements to avoid mis-packaging, incomplete packages, and material waste.

3. Role of Motors in the System

The requirements for the motor system in a packaging machine are extremely high, and its role is critical in the following areas:

• High-Precision Synchronous Control: Multiple servo motors work together to control various belts and forming rollers, ensuring seamless synchronization of packaging speed and rhythm.
• Precise Metering Drive: Stepper motors control the metering device, ensuring consistent weight in each bag, reducing food waste and improving product quality.
• Stable Sealing and Cutting: Motors drive sealing wires and cutting tools, with fast and precise movements to avoid bag deformation or damage.
• Durability and Safety: Motors need to be highly dustproof and waterproof (IP54 or above), suitable for the humid, high-temperature environment of food factories and easy to clean and maintain.
• Energy Efficiency and Low Noise: High-efficiency motors and advanced drive technology reduce energy consumption and noise, enhancing the working environment comfort in the factory.

4. Customized Motor Solutions

For the food machinery industry, we offer dedicated servo motor solutions for multifunctional packaging machines. We recommend the GPG-SV85 series high-response servo motors, which provide high-speed, high-torque output and excellent dynamic response capability to meet the needs of multi-axis coordination and complex motion control. Equipped with high-precision encoders, they provide micron-level position feedback to ensure synchronized and precise forming, sealing, and cutting actions. The motors are coated with food-grade protective coatings and corrosion-resistant materials, meeting food safety and hygiene standards, and are designed to work in high-temperature and high-humidity environments. They also support multiple industrial communication protocols, facilitating integration with PLCs, motion controllers, and other devices, enhancing the system's overall intelligence.

Additionally, this solution offers customizable options, allowing for flexible motor parameter adjustments based on packaging material types, product specifications, and production line speeds. This ensures optimal matching, maximizing packaging efficiency and quality. By adopting this solution, food companies can effectively improve automation levels, reduce labor costs, and ensure the efficiency, stability, and food safety of the packaging process.
