I. Technical Requirements
Coating machine need to glue or ink material evenly adhered to the surface of aluminum foil, plastic film or cloth fabric, the coating process requirements are relatively high, not only require coating height uniformity and to be able to achieve high speed and no downtime to improve production efficiency.
II. Programme advantages
1, by the frequency converter to complete the tension control at all levels, the use of tension sensors to achieve tension control, the system is simple and stable. Using PLC or synchronous controller to control the speed of drive roller inverter, and as the line speed signal of other inverter.
2, S350 closed-loop tension control (inductive vector control) easy to achieve the acceleration and deceleration process of tension constant, save the installation of tension roll space, reduce mechanical costs, while high-precision control to ensure that the coating effect is highly uniform.
3, dual-station retractable roll has the pre-drive function, can meet the high speed of automatic volume change, improve production efficiency needs. At the same time, accurate coiling control can avoid the bad heart-type rewinding, so that the effect of rewinding is better.
