Fabric edge control and frequency conversion speed regulation of fabric stenter

- Aug 15, 2018-

The fabric edge control of the fabric stenter is mainly controlled by its 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 inverter motor. The control system adopts all-digital type, and the inverter, PLC, touch screen and display are integrated into one.

The circulating fan of the fabric stenter 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 blowing pipe adopts the punching nozzle type, and the upper and lower wind speed ratios can be adjusted. The control system of the equipment is mainly composed of a color touch screen, a high-performance small H-band two 40-point expansion modules and a high-performance inverter.

The fabric stenter is mainly controlled by the inverter through the agreement of the main shaft, the lower over position, the upper over position and the brush wheel. The common DC bus method reasonably distributes the energy of the equipment during the start and stop process. Consumption increases the stable operation of the equipment and the efficient use of energy.

Stretching finishing means that the fabric of a certain moisture content and the hygroscopic chemical fiber are gradually widened to a predetermined size on a stenter, and simultaneously heated and dried to eliminate part of the internal stress and coordinate the warp and weft state. The process of making the fabric uniform and stable, and improving the weft and the like.
