ZF-D200 Series Packaging Machinery Servo Drive Systems

The servo system of textile machinery is one of the core technologies for achieving efficient and precise production in modern textile industry. It achieves high-precision control of textile machinery movement through the collaborative work of servo motors, drivers, controllers, and feedback devices.

1. Core Components

• Servo motor: Adopting permanent magnet synchronous motors or asynchronous motors, with high speed, high torque density, and fast response characteristics, it can adapt to the high-speed and high-precision motion requirements of packaging machinery.
  Driver: Responsible for converting control signals into motor drive signals, supporting three control modes: position, speed, and torque, and possessing functions such as overload protection and fault diagnosis.
  Controller: Based on PLC or dedicated motion control chips, achieve multi axis collaborative control, trajectory planning, and process parameter adjustment, and support fieldbus communication (such as EtherCAT, CANopen).
  Feedback device: Using encoders (such as photoelectric encoders, magnetic encoders) or rotary transformers to provide real-time feedback on motor position and speed information, forming a closed-loop control.

2. Key Features

• High precision control: Through closed-loop feedback and advanced control algorithms, a position accuracy of ± 0.01mm and a speed accuracy of ± 1rpm are achieved, meeting the stringent requirements of packaging machinery for parameters such as film tension, packaging bag length, and sealing position.
  Fast dynamic response: The response time of the servo system is usually less than 5ms, which can quickly adjust the motor speed and torque, and adapt to the frequent start stop and acceleration/deceleration requirements in the packaging process.
  Energy saving and efficient: By adopting vector control and weak magnetic control technology, the motor efficiency can reach over 95%, significantly reducing energy consumption.

3. Applications

• Pillow type packaging machine
  Film feeding control: The servo system drives the film feeding motor to ensure stable film tension and avoid wrinkles or breakage of the packaging bag.
  Sealing control: The horizontal and vertical sealing mechanisms are driven by servo motors to achieve precise control of sealing temperature and pressure, ensuring a firm and aesthetically pleasing seal.
  Cutting control: The servo system controls the position and speed of the cutting blade, achieving precise cutting of packaging bags and reducing material waste.
  Vertical packaging machine
  Measurement filling: The servo system drives the measuring device to ensure precise control of the material filling amount and improve packaging accuracy.
  Bag molding control: The molding machine is driven by a servo motor to achieve rapid molding and stable transportation of packaging bags.
  Shrink packaging machine
  Heat sealing control: The servo system drives the heat sealing knife to achieve precise control of heat sealing temperature and time, ensuring the sealing of the packaging bag.
  Conveyor control: The conveyor belt is driven by a servo motor to ensure smooth operation of the product during the thermal shrinkage process.
  Fully automatic packaging machine
  Binding control: The servo system drives the binding mechanism to achieve fast and secure binding of the strapping tape.
  Tension control: Adjust the tension of the packing belt through a servo motor to avoid the packaging being too loose or too tight.
