What Is Hot Air Stenter Setting Machine

The shape of the Hot Air Stenter setting machine is similar to hot air stenter, only the heating system requirements are different so we always confuse two machines. The hot air stenter setting machine is a high temperature machine, which is different from the hot air stenter, which can’t be ignored, otherwise it will be difficult to adjust the amplitude and the deformation of the cloth edge during operation. Therefore, it should be designed in consideration of the deformation of the fabric during high temperature operation, the expansion of the guide rail, the adaptability of the amplitude modulation screw to high temperature operation, etc.

The heat setting machine is mainly composed of a feeding device, a preheating zone, a high temperature setting zone, a cooling zone and a cloth discharging device. The feeding device is made of a tension frame, a weft feeder, a suction device, an overfeeding device, an automatic control device, an edge detector, etc. The function of the feeding device is to make the fabric perpendicular to each other under a certain tension or a certain relaxed state, and can smoothly enter into the machine. Then the fabric is heated to a certain temperature through the top hot zone to avoid the cold forming fabric directly entering the high temperature setting zone and affecting the setting temperature.

The temperature of the preheating zone should be controlled at around 100℃. The preheated fabric enters into the high temperature setting zone (with steam heating and electric heating device), and the temperature is controlled at 150~230℃, so that the fabric is evenly heated for a certain time. After meeting the setting requirements, the cooling zone is cooled rapidly, and finally, the cloth is discharged. The falling cloth frame was dropped out of the machine. The operation of the fabric in the machine is driven by a chain of crepe chains or needle plates and fabrics. A static eliminator must be installed at the fabric outlet, or a steam vent and a metal screen should be installed in front of the fabric roller to spray a proper amount of steam on the cloth surface to appropriately increase the moisture regain of the fabric and reduce the generation of static electricity.
