Curtain fabric coating machine is mainly used for the surface coating process of film, paper, etc. This machine is to apply a layer of specific function glue, paint or ink to the roll substrate, and then wind it up and wind up. It adopts a special multi-functional coating head, which can realize various forms of surface coating. The rewinding and unwinding of the coating machine is equipped with a full-speed automatic film-bonding mechanism, and the PLC program tension closed-loop automatic control.
The curtain fabric coating machine needs to evenly adhere the glue or ink substance to the surface of the aluminum foil, plastic film or cloth textile. The coating process requirements are relatively high, not only the coating height is required to be uniform, but also the high speed non-stop changeable volume can be realized to improve Productivity.
The curtain fabric coating machine completes the tension control of each stage by the frequency converter, and uses the tension sensor to realize the tension control. The system is simple and stable. The speed of the drive roller inverter is controlled by a PLC or a synchronous controller, and is used as a line speed signal of other inverters. With the addition of S350 closed-loop tension control, it is easy to achieve constant tension during acceleration and deceleration, save space for installing tension roller, reduce mechanical cost, and high-precision control ensures a highly uniform coating effect.
In addition to this digging, the double-position retractable roll of the curtain fabric coating machine has a pre-drive function, which can meet the requirements of high-speed non-stop automatic roll change and increase production efficiency. At the same time, accurate winding control can avoid the bad heart-winding and make the winding effect better.
