The drive system of paper tube making machine  equipment includes website, exploitation department, macro steel, glue mixing, polishing, unwinding, etc. In order to satisfy production requirements, the drive system of paper tube making machine equipment must be able to maintain the speed per hour within a certain business scale, and the speed of each branch can be maintained independently. In order to avoid cracking, bending, wrinkles and embossing of the paper, high-precision speed operation must be carried out for each drive system point, and a certain speed cascade of the paper web must be maintained from flow desizing to paper unwinding, so as to have tensile resistance.

What is more, the DC frequency conversion operation of the drive system of each sub section focuses on the free online speed change and simultaneous follow-up effect of each drive system point. Therefore, the soft starter used in the drive system of each sub section must have the following rules:

The variable speed operation scale of paper tube making equipment is wide, and the output power must be about 90% within the full speed operation scale; Power factor is higher than 0.9; The total frame loss of the input current is less than 3%; Select standard components IGBT with high reliability and mature professional skills; It can reduce the output pulse current, dv/dt noise and torque ripple reasonably; High speed serial transmission of statistical data using communication effects.

The DC frequency conversion operation method of paper tube making machine equipment is a comprehensive operation method based on listening to the opinions of load configuration, static data compensation and support force operation on the basis of speed cascade. Speed cascade is to shape the speed value chain. There are two methods: choose the same method operation card, which is an open loop operation, and the appropriate speed is less than 300n/min for small and medium-sized paper machines; Communication operation refers to the whole process of shaping, installing, and communicating among soft starters. This method can quickly transmit the given value of speed to the soft starter in large digital quantities. The different mechanical equipment changes between the two methods can be operated by the different market share coefficients within the soft starter, so as to conduct constant market share operation at the angular speed of each division in daily dynamic and steady state.
