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

Moreover, the DC frequency conversion operation of each divisional transmission system focuses on the free online transmission and synchronous tracking effect of each transmission system point. Therefore, the soft starter used in each divisional transmission system must have the following rules:

The variable speed operation scale of automatic paper core 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 amount is less than 3%; Select standardized IGBT components with high reliability and mature professional skills; The practical effect of reducing the component of output pulse current and reasonably reducing dv/dt noise and torque pulsation; Use communication effects for high-speed serial transmission of statistical data.

The method for DC frequency conversion operation of paper tube making equipment is a comprehensive operation method that listens to opinions based on speed cascade, including load configuration, static data compensation, and support force operation. Speed cascade is a comprehensive operation method that aims to shape the speed given value chain. There are two methods: selecting the same method operation card, using this as an open loop operation, and suitable for small and medium-sized paper machines with a speed of less than 300 n/min per hour; Communication operation refers to the entire process of molding, installing, and communicating between each soft starter. This method can quickly transmit the given rate value to the soft starter in large digital quantities. In both methods, different mechanical equipment changes between segments can be operated by different market share coefficients within the soft starter, allowing constant market share operation of the angular velocity of each segment in daily dynamic and steady-state situations.
