In the process of production, we need to use a tent fabric coating machine to evenly adhere the glue or the ink-like material to the fabric textile surface. Under normal circumstances, the requirements for the coating process are relatively high. On the one hand, a uniform coating height is required. On the other hand, it is required that the tent fabric coating machine can achieve high-speed, non-stop, rewinding, thereby increasing production efficiency.
In order to achieve such an effect, when using a tent fabric coating machine, it is possible to use a frequency converter to perform tension control at all levels and use a tension sensor to achieve tension control. The system is simple and stable. At the same time, PLC or synchronous controller can also be used to control the speed of the drive roller, and it is also used as the line speed signal of other inverters. Among them, S350 closed-loop tension control easily achieves constant tension during acceleration and deceleration.
Not only that, it can also save the space of the tension roller and reduce the use cost. At the same time, the high-precision control ensures that the coating effect of the tarpaulin fabric coating machine is highly uniform. Moreover, the duplex retracting and unwinding roll configured therein has a pre-driver 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 bad heart-type winding, so that the winding effect is better.
The working principle of the tent fabric coating machine is basically the same, but its performance is generally different for different models and different manufacturers. Means for clamping the frame are usually provided on the vertical frame. Prior to coating, a clean, stretched screen is installed from the front, and some models can also be loaded from the side into the screen.
For example, when the automatic tent fabric coating machine is used in combination with other related processing equipment, such as when connecting cleaning equipment, recycling equipment, drying equipment, and developing equipment, side loading is more convenient. At present, the working process of the tarpaulin fabric coating machine can be roughly divided into: unwinding, preheating, coating, drying, cooling and then winding.
