In recent years, as people look for packaging style and quality requirements, printing and packaging technology has a lot of progress, finishing technology is made more vigorous development, and hot stamping machine(commonly known as "bronzing ") as a part of India after finishing, can improve the value-added and technology content of the print.
The material properties of the paper itself is brittle, when winding tension control requirements are very stable, otherwise the paper is easily pulled off, seriously affect the stamping quality. Paper products in the past on the winding tension control plus the widespread use of magnetic clutches, magnetic clutches is based on electromagnetic theory using magnetic transfer torque. Magnetic long-term use will occur in the oxidation and wear, causing a torque smaller, so must be frequently changed, the use of high cost and frequency of maintenance required.
With inverter technology, the world's leading brands in industrial automation subsidiary of Delta - CIMIC through active exploration, successfully bronzing machine winding drive application, equipment maintenance can be done to improve the speed of rolling and accuracy, while reducing the customer's use of cost effective, enhance the competitiveness of tipping machine.
The project uses Delta VE inverter winding machine for tipping control, mainly due to Delta VE using FOC + PG converter can achieve zero-servo control functions, the motor at full load conditions, the motor speed is control is very stable, which effectively address the traditional V / F control at low speed, the speed control instability, leading to severe fluctuations in tension when the Jumbo issue.
According to the charge of the project application CIMIC industry experts, the project control system, while not complex, but the control is very high, thanks to the tension sensor feedback, but the tension sensor to respond faster than the floating roller and allow to adjust the amount is very small, so the required motor speed so quickly, so CIMIC specialists in the motor industry applications to install a 1000-line VE AB phase encoder with frequency control, the motor itself to do FOC + PG control, improve motor response speed and control accuracy.
