Stretching definition and control system composition of air stenter machine

- Apr 01, 2019-

The tentering of the air stenter machine means that the fabric of a certain moisture content and the hygroscopic chemical fiber are gradually widened to a predetermined size on the tenter, and simultaneously dried and dried to eliminate part of the internal stress. Coordinate the warp and weft yarns, make the fabric uniform and uniform, and improve the process of weft and so on.


The edge of the air stenter machine is controlled by an infrared edge detector; the transmission system adopts AC frequency conversion speed regulation; the upper and lower super feed, the brush wheel and the cloth are synchronously operated by the synchronous motor and the main drive frequency conversion special motor; the control system It adopts all-digital type, and the inverter, PLC, touch screen and display are integrated into one communication mode. The circulating fan of the tenter setting machine adopts AC frequency conversion speed regulation, and the motor and the fan are directly connected; the temperature of each drying room is automatically controlled separately; the air blowing pipe adopts the punching nozzle type, and the upper and lower wind speed ratios can be adjusted.


The key point to understand is the control system of the air stenter machine, which consists of a color touch screen, a high-performance small PLC and a high-performance inverter. The main shaft of the air stenter machine, the lower over position, the upper over position and the brush wheel are synchronously controlled by the frequency converter through the Modbus protocol. The common DC bus method reasonably allocates the energy consumption of the equipment during the start and stop process, and improves the equipment. Stable operation and efficient use of energy.
