Description

1ã��usage This model is special equipment for heat-sensitive paper production, Which can realize CB and CF respectively .This machine has characteristic of high efficiency production, low energy consumption, stable performance, lower wastage of base paper, high yield rate. 2ã��Technical characteristics 2.1Tension Control: Stable tension control is the guarantee for the equipment normal working . As for the higher speed, lower base paper weight , the main speed of total machine adopts PLC programmable controller and modulecan to achieve automate closed-loop digital control. And also through rottery encoder, proximity switch and the signal of tension transducer, it can achieve high precision closed-loop control and can realize the tension precision within ***** to reduce the probability of paper breaking and improve the ratio of production and yield. 2.2Error Correction System: This model is used for top grade heat-sensitivity ***** order to ensure the efficiency and finished rate of finished paper follow up-cutting , so we setting the automatic error correction device at the rewinding section. 2.3Digital Controlling System The whole machine is driven by alternating current vector VFC of micro-computer. The stability of performance is guaranteed by the application of centralized control system of 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.High precision and high speed data calculation, exchange and control are achieve, eventually, digital control is guaranteed. This machine has the features of simple operation and high degree of automation. All parameters are adjusted to the best condition before they leave the factory. The only thing you need to do is to enter the data of speed and tension, then the whole machine can be automatically and simultaneously controlled. 2.4 Double-speed twin-roll calendering device To improve the surface quality of finished paperï&frac*4;�to increase the smoothness of finished paper, in addition to maintain the finished product thickness to maximum, the machine adopt double-speed twin-roll calendering device. In the case of a low line pressure to improve the smoothness of paper.
