Another type of drive also is to adopt same servomotor that power is provided, and adopts band connection simultaneously synchronously to drive two rollers, comes assurance speed synchronous by the diameter machining accuracy of applicator roll and carry-over pinch rolls fully.Because the restriction of domestic level of processing, in full accord being difficult to of processing diameter of two rollers reaches; After the wearing and tearing of applicator roll or carry-over pinch rolls, just can't satisfy synchronism, do not regulate way, reconditioning again, replacing two rollers, its difficulty, consuming time and cost is all very big yet.
And as Fig. 2, the separately-driven mode of domestic employing is many, and namely 2 two rollers of applicator roll 1 and carry-over pinch rolls adopt two servomotor 5 drive respectively.This kind mode just arranges parameter in man-machine interface and regulates two roller speed theory synchronously, saved the trouble of artificial debugging buncher 6, reconditioning, roll change, but the speed of servomotor 5 also is theoretic synchronous relatively synchronously, its absolute synchronization also can't satisfy the control requirement of foil 11 tension force between two rollers, can influence the coating precision equally.
