Application of TETRANCA Frequency Converter in Packaging and Packing Industry
Process requirements:
1, food packaging machine mainly completes the functions of forming, positioning, packaging and sealing.
2, The bag length can be consistent when starting, stopping and adjusting the number of bags.
3, the core control components should have stable performance and fast response.
4, the equipment can work in a dusty environment.
System program:
The system consists of sealing and cutting part, heating part, frequency conversion speed control part, electrical control part and so on. Sealing and cutting part of the main package to complete the horizontal and longitudinal package; heating part of the main cross-seal and longitudinal sealing knife heating, and temperature control; frequency conversion speed control part of the main drive cross-cutting knife sealing and cutting and adjusting the speed of the packaging film stretching speed, and its speed determines the packaging speed of the packaging machine; electrical control part of the main use of PLC and TETRANCA T510 series frequency converter as the core control elements of the packaging machine, signal processing. Carry out signal processing.
According to the encoder feedback signal, the system carries out speed closed-loop control; PLC outputs two PWM waves as the frequency feed source of the two inverters, and the change of PWM wave pulse width regulates the output frequency of the inverter.
System features:
1, the main electrical components using TETRANCA Electric products, has a high cost advantage. T510 inverter unique PWM pulse width to set the frequency function, larger low-frequency torque, fast dynamic response and strong overload capacity.
2, the use of dual frequency conversion stepless speed control, a wide range of adjustment; each sealing temperature using a digital display temperature controller independent control; high sensitivity electric eye automatically tracking the package, the use of touch-screen man-machine interface, intuitive and convenient.
3、The equipment runs stably, seals and cuts accuratel
