Structural Characteristics of Hot Air Stenter Machine II


As mentioned in the previous news, the Hot Air Stenter machine is mainly composed of the feeding part, the weft feeder, the chain, the oven body, and the falling cloth. Apart from that, chemical systems and oil furnace heating systems is also included.

4. Oven body.

The hot air setting machine has eight sets of ovens. Under the action of the circulation fan, the air is continuously sprayed on the cloth surface by the fine holes on the star-shaped jet rack. After the hot air contacts the wet cloth, the temperature drops and the humidity rises, discharged from the large hole in the star-shaped jet frame, passing through the filter, continuously circulated after being heated by the heat exchanger which is located below the filter with hot oil. The heat exchanger has many thin fins for efficient heat exchange.

5. Falling cloth and rolling device.

The setting machine can be arranged in two ways, depending on the production needs, in the form of a cloth or a roll. Both methods are driven by a motor to drive the chain. When the cloth is discharged by the roll cloth, the tension stability of the cloth is required to be high, and the cloth needs to pass through a tension adjusting guide roller controlled by the air cylinder. In the case of a cloth-type drop cloth, the cloth does not need to pass through the tension adjusting roller to change through a fixed guide roller.

The working principle of the setting machine is as follows: The unshaped cloth is fed into the machine by the flat stripper, and the machine automatically attaches the two ends of the cloth to the needle board. Both ends of the needle board enter the oven with the mechanical running step, the oven is heated by electric, and the fan is blown. After several consecutive constant temperature ovens of different temperature sections, after entering the tail end and cooling to static electricity, the swing falls into the cloth, and the cloth is crisp and beautiful. Stretching is generally used for chemical fiber products such as polyester.
