Specification

1,usage

This is NCR paper production equipment, which can achieve the two-sided coating at the same time. Especially suitable for NCR paper production with the features of high efficiency of production, low energy consumption, stable performance of equipment, low consumption of base paper, and high yield.

Paper Refunding Part and Rewinding part both adopts double rotating arm for automatic continuous Refunding and Rewinding , convenient and fast change, reduce the loss of base paper, convenient roller changes, enhanced the production efficiency, improve the yield, reduce the labor intensity, reduce the production cost

2. Tension Control:

Stable tension control is the guarantee for the equipment normal working. As for the higher speed, lower base paperweight, the main speed of total machine adopts SIEMENSE PLC programmable controller and module can to achieve automate closed-loop digital control And also through rotary encoder, proximity switch and the signal of tension transducer, it can achieve high precision closed-loop control and realize the tension precision within 1kg,furthermore to reduce the probability of paper breaking and improve the ratio of production and yield.

3.Digital Controlling System

The whole machine is driven by alternating current vector VFC of microcomputer. The stability of performance is guaranteed by the application of centralized control system of SIEMENSE PLC programmable controller and digital control module. Man-computer interaction is achieved by industrial man-machine interface, meanwhile the calculation, monitor and machine connection communication are achieved as well. Digital control is guaranteed by high precision and high-speed data calculation, exchange and control are achieved, eventually. This machine has the features of simple operation and high degree of automation. All parameters are adjusted to the best condition before leaving the factory. The only thing you need to do is to input the data of speed and tension, then the whole machine can be automatically and simultaneously controlled.
