The transmission system of the paper tube making machine includes a website, exploitation department, Honggang, glue mixing, polishing, unwinding, and other parts. To meet the production requirements, the transmission system of the paper tube equipment must be able to maintain the speed per hour within a certain operating scale, and the speed of each branch can be independently maintained. To avoid cracking, bending, wrinkles, and imprinting on the paper, it is necessary to carry out high-precision speed operations on each transmission system point, and maintain a certain rate cascade of paper web from flow desizing to paper unwinding, in order to have tensile resistance.

Moreover, the DC variable frequency operation of each sub transmission system emphasizes the free online transmission and synchronous following effect of each transmission system point. Therefore, the soft starter used in each sub transmission system must have the following rules:

The variable speed operation scale of spiral paper tube making machine is wide, and within the full speed operation scale, the output power must be around 90%; The power factor is higher than 0.9; The total frame loss of the input current is less than 3%; Select standardized IGBT components with high reliability and mature professional skills; The actual effect of reducing the component of output pulse current and reasonably reducing dv/dt noise and torque pulsation; High speed serial transmission of statistical data using communication effects.

The method of DC frequency conversion operation for automatic kraft paper tube machine is a comprehensive operation method that listens to opinions on load configuration, static data compensation, and support force operation based on rate cascading. Rate cascading is to shape the rate given value chain, and there are two methods: using the same method to operate the card as an open-loop operation, suitable for small and medium-sized paper machines with a speed less than 300n/min; Communication operation refers to the entire process of shaping and installing communication between each soft starter. This method can quickly transmit the rate given value to the soft starter in large digital quantities. Both methods can be operated by varying market share coefficients within the soft starter, allowing for constant market share operation of the angular velocity of each branch in daily dynamic and steady-state situations.
